Background

A snow maker is a device for making artificial snow, and is generally used in a large amount in places such as a ski resort and an ice rink. The snow making machine is usually used in low temperature environment, and the snow making principle is that high pressure water and high pressure air are sprayed out through a nucleon to form snow nuclei with small grain size, and then the high pressure water is sprayed out from a nozzle in an atomized manner and is collided with the snow nuclei to form snowflakes, so that the snow making is realized.

Therefore, the nozzle and the nuclear device are used as core components for realizing atomization of the snow making machine, and the respective atomization performances and the mutual matching relationship of the nozzle and the nuclear device can directly influence the snow making effect. In the prior art, when the snow making machine is developed and produced, the requirements on the spray head and the nuclear device are designed and produced according to the knowledge of fluid dynamics flow field theory and the like, and the designed and produced product is directly assembled on the snow making machine and then the actual effect is detected. Because the whole circle of spray heads and the nucleon devices are required to be arranged on the whole periphery of the outlet of the air duct on the snow making machine, the detection mode has the defects of higher cost, inconvenient use and the like.

Thus, when the test system is used, the nozzle is arranged on the nozzle module, the nuclear device is arranged on the nuclear device module, then the water pressure and the air pressure of the working condition of the test system can be simulated through the water supply system and the air supply system, and the actual working condition of the test system is restored (usually, the required air pressure is stabilized at about 0.8MPa, and the water pressure is stabilized at about 3 MPa); and then, the particle size issuing data and the particle size speed field data of the water mist sprayed by the atomizing member can be detected by a particle size tester to obtain the particle size range and the Sott average particle size of the water mist, and the atomizing cone angle size of the water mist sprayed by the atomizing member can be obtained by shooting pattern data by a camera. Therefore, the atomizing performance of the nozzle and the nuclear device can be detected, so that whether the nozzle and the nuclear device are qualified or not and whether the required matching atomizing effect is achieved or not can be judged.

Like this, the test jig structure is very simple but all very stable equilibrium including the fixed atress of installation of each component such as atomizing component installation module, particle size tester and camera, and the water pipe and the trachea of connection can overlap joint downwardly extending again in the left and right sides of top installation frame, avoid the interference to the detection. During detection, the atomization component downwards sprays water mist from the middle part of the front end of the top mounting frame above the atomization component, an atomization flow field is formed in the middle position of the middle mounting frame, and then data detection is realized by means of a particle size tester and a camera. Therefore, the structure can facilitate the installation and fixation of each component, and has the characteristics of simple, stable and reliable integral structure and contribution to realizing detection.

Further, the lower surface of the middle part of the front side of the top mounting frame is provided with a ferromagnetic component and forms a module mounting station, and the upper end surface of the atomization component mounting module is made of ferromagnetic materials.

Like this, the structure is very simple and make things convenient for atomizing component installation module to fix on the installation station with the mode installation of ferromagnetic actuation, like this in the testing process, when needing to dismantle the atomizing constitution installation module of changing, the operation is very convenient and fast. Meanwhile, during testing, because the atomizing component sprays downwards, the mounting module can be upwards and firmly attracted and fixed on a mounting station under the action of the spraying reaction force, and cannot fall off, so that the stability of the test can be ensured. Certainly, during concrete implementation, fixing of the installation module on the installation station can be achieved in a binding mode and the like, so that the installation module can be conveniently detached and replaced during detection.

Further, the rear end of the middle mounting frame as a whole projects rearward along the support frame by a distance of 3m and a camera is mounted at the middle position thereof.

Therefore, the flow field effect shot by the camera can be better ensured.

Furthermore, one end of the upper part of the nozzle module along the left and right direction protrudes outwards to form a connector with external threads, the other end of the upper part of the nozzle module is provided with a connector with internal threads, the external threads of the connector are matched with the internal threads of the connector, the lower end of the nozzle module is provided with a downward nozzle interface, the nozzle interface is provided with internal threads matched with the external threads of the nozzle mounting end, and the connector, the connector and the nozzle interface on the nozzle module are communicated with each other through inner cavities; the utility model discloses a nuclear ware installation, including nuclear ware module, the one end evagination of nuclear ware module upper portion along left right direction is formed with a connector of outband screw thread, the external screw thread of the connector of nuclear ware module matches and connects the cooperation soon with the internal thread of the connector of nozzle module fixedly, the evagination of the other end of nuclear ware module lower part is formed with a trachea connector, nuclear ware module lower extreme is provided with a nuclear ware interface downwards, the nuclear ware interface has the internal thread that matches with the external screw thread of nuclear ware installation end, the inside trachea connector direction that just link up of nuclear ware interface is provided with a chamber of gathering gas, the air inlet is located the chamber of gathering gas after the nuclear ware installation, the chamber of gathering gas upper end passageway and the connector of nuclear ware module communicate with each other, the installation end upper portion inserts the cooperation in the chamber of gathering gas.

Like this, the connector of nozzle module and the connector of nucleon ware module all can realize and water supply system water pipe's general connection, and the trachea connector of nucleon ware module can be connected with air supply system. Therefore, in the atomization component mounting module, the nozzle module and the nuclear device module are detachably arranged, and can be independently mounted after being detached respectively so as to respectively detect the respective atomization effects of the nozzle module and the nuclear device module; the nozzle module and the nuclear device module can be assembled and then installed on a module installation station to detect the atomization effect after the nozzle module and the nuclear device module are matched. And the connection with the air supply system and/or the water supply system can be conveniently and rapidly realized under various conditions. The operability of the test is greatly improved, the operation steps are simplified, and the test efficiency is improved.

Furthermore, the connector plug is further included, and an external thread matched with the internal thread of the connector is arranged on the connector plug.

Like this, when carrying out nozzle module test alone and need plug the connector, adopt connector end cap to carry out shutoff operation convenient and fast more.

Furthermore, the nozzle modules are provided with two connectors, the connectors of the nozzle modules on the outer sides are fixedly butted with the water pipes, the connectors of the nozzle modules on the outer sides are fixedly butted with the connectors of the nozzle modules in the middle, and the connectors of the nozzle modules in the middle are butted with the connectors of the nuclear device modules.

Therefore, the atomization matching effect between the two nozzles and the nuclear device can be conveniently detected.

Furthermore, the lower ends of the nozzle module and the nuclear device module are arranged in a ladder mode, so that the dislocation distance between the installed nuclear device and the nozzle is consistent with the actual installation dislocation distance.

Therefore, the actual positions of the simulated nozzle and the nuclear device during installation are detected, and the accuracy and the applicability of the detection result can be better ensured.

Further, nozzle module lower part still is provided with nozzle interface adjustment mechanism, and nozzle interface adjustment mechanism includes that a solid-state just wholly is the installation cover of tube-shape, and the installation cover inner chamber is provided with the internal thread that matches with nozzle installation end external screw thread and constitutes the nozzle interface, adjustment mechanism can adjust the inclination of installation cover.

Like this, rely on adjustment mechanism to adjust installation cover inclination, and then can realize the regulation to nozzle installation angle, and then can realize the detection to the cooperation atomization effect between the nozzle of different angles and the nucleon ware. Thus, when the test device is used for product design test, the inclined matching angle of the optimal atomization effect between the nozzle and the nuclear device can be detected. When the device is used for detecting the product quality, the actual installation angle between the nozzle and the nuclear device can be better simulated for detection, and the product quality can be more accurately reflected.

Therefore, based on the device, the invention actually discloses a design method of an atomization component of the snow making machine, namely after determining the respective model sizes of the nozzle and the nuclear device (the respective model sizes of the nozzle and the nuclear device can be correspondingly determined according to the model size of the snow making machine per se according to experience), the nozzle and the nuclear device are parallelly installed together and connected into a water supply system and a gas supply system, the working condition of the water supply system and the gas supply system is simulated for testing, the deviation angle size between the nozzle and the nuclear device is correspondingly adjusted (can be adjusted according to the size of 1-3 degrees each time) in each test, the coupled atomization flow field condition is detected and recorded, and when the particle size distribution range of the coupled water mist flow field is the minimum, the installation angle size between the nozzle and the nuclear device is the optimal matching design angle size of the nozzle and the nuclear device of the model. Thus, the snowflake making machine obtained by the design method can make snowflake effects with the most uniform and stable particle size and the highest efficiency, and can obtain the best snowflake making effect.

Specifically, as an optimized structure form of the nozzle interface adjusting mechanism, the nozzle interface adjusting mechanism further comprises a crimping block, the edge of the crimping block is detachably fixed at the lower end of the nozzle module by means of screws, an opening is formed in the middle of the crimping block and faces the opening at the lower end of the inner cavity of the nozzle module, the outer drums of the opening of the crimping block and the opening at the lower end of the inner cavity of the nozzle module are integrally formed into an integrally circular mounting cavity in the left-right direction (namely the direction of a vertical plane where the nuclear instrument and the nozzle are located after the nuclear instrument is mounted), the outer drums of the outer surface of the mounting sleeve are matched in the left-right direction, the mounting sleeve is tightly pressed and fixed in the mounting cavity, and the lower end of the mounting sleeve is provided with a section of part exposed out of the crimping block.

Like this, because installation cavity and installation cover surface all are the circular and installation cover lower extreme that match have one section to expose in the part of crimping piece, so after loosening the screw, can rotate the direction of installation cover, adjust inclination, then rely on the screw to compress tightly fixedly again. Therefore, the adjusting device can conveniently and quickly adjust the installation angle between the nozzle and the nuclear device, and has the advantages of simple structure, quick, convenient and reliable adjustment and the like.

Further, an elastic material layer is arranged on the outer surface of the mounting sleeve and/or the inner surface of the mounting cavity.

Therefore, sealing can be better realized, and the pressing and fixing effects on the mounting sleeve can be guaranteed.

As another structure form of the nozzle interface adjusting mechanism, the upper end and the lower end of the mounting sleeve are connected with the nozzle module through flexible sealing materials, the periphery of the mounting sleeve is made to enclose an adjusting area capable of deforming flexibly, magnetorheological fluid is filled in the adjusting area, and electromagnets are further mounted at the left end and the right end of the adjusting area (namely the direction of a vertical plane where the nuclear reactor and the nozzle are located after the nuclear reactor is mounted).

Thus, when installed therein, the magnetorheological fluid should be within the range of the action of the magnetic field of the electromagnet. When the electromagnet is powered off, the magnetorheological fluid is fluid, and the deflection angle of the installation sleeve in the left and right directions can be freely adjusted; after the angle of the mounting sleeve is adjusted in place, the electromagnet is switched on, and the magnetorheological fluid becomes hard under the action of the magnetic field to fix the angle of the mounting sleeve. Therefore, the deviation angle between the installed nozzle and the nuclear device can be conveniently and quickly adjusted by utilizing the characteristics of the magnetorheological fluid. Meanwhile, a section of flexible sealing material is connected between the upper end of the mounting sleeve and the nozzle module in the structure; therefore, the structure can also realize the adjustment of the mounting sleeve in the height direction and the angle difference in other directions according to the requirement. Therefore, when the device is used for quality detection, the actual conditions of the angle deviation (including the angle deviation in the horizontal direction and the angle deviation in the vertical direction) and the height deviation between the nozzles and the nuclear instrument of different product types can be better simulated; greatly improving the quality detection effect. When the device is used for designing an atomization component product, the device can also adjust the nozzle and the nuclear device to be in different angle deviations in the vertical direction and the horizontal direction and to be in different distance conditions in the height direction in each test, atomization flow field data after coupling in different conditions are detected and recorded, and when the particle size distribution range of the coupling water mist flow field is the minimum, the size of the installation angle and the height difference (namely the difference in the front-back direction) between the nozzle and the nuclear device are the optimal matching position of the nozzle and the nuclear device of the type. This results in a relative position between the nozzle and the nucleator that produces the maximum snowmaking effect (including data on the magnitude of the horizontal declination angle, the magnitude of the vertical declination angle, and the magnitude of the height-wise distance). Ensuring that the designed snowmaker has the best snowmaking effect.

When the device is used for detection, the performance parameters of the water mist flow field sprayed by a single nozzle and a single nuclear device in respective working states can be respectively detected, and whether the requirements are met or not is judged; and then matching a single nozzle and a single nucleon device which meet the requirement, detecting the performance parameters of the coupling water mist flow field sprayed out in the working state, and if the particle size distribution range of the detected coupling water mist flow field is larger than the maximum value of the particle size distribution range of the single nucleon device and is smaller than the maximum value of the particle size distribution range of the single nozzle, judging that the nozzle and the nucleon device meet the matching requirement.

Therefore, the performance detection of the nozzle and the nuclear device can be independently completed, and the coupling detection is carried out on the nozzle and the nuclear device which meet the performance. According to the principle of snowmaking of the snowmaking machine, the water mist flow field sprayed by the nozzle and the water mist flow field sprayed by the nuclear device can simultaneously generate the crushing function and the fusion function of water mist droplets when being coupled and collided. And during coupling, if the Sott average diameter of the water mist flow field is reduced, the collision crushing effect between the liquid drops is stronger than the mutual fusion, otherwise, the mutual fusion effect is larger than the collision crushing effect. Therefore, if the water mist flow field of the nozzle is coupled with the water mist flow field of the nuclear device, more water mist droplets with small particle sizes sprayed by the nuclear device can be enlarged after being fused, and if the water mist droplets with relatively large particle sizes sprayed by the nozzle can be crushed by collision as much as possible, the snow making effect can be better improved. Therefore, by adopting the detection method, the quality of the matching snow making effect between the nozzle and the nuclear device can be detected, and whether the detected nozzle and the nuclear device are matched appropriately or not can be judged. Therefore, a better judgment method can be provided for the design and the actual effect detection of the snow making machine.

More specifically, the device may specifically include the following steps:

1) completing the atomization characteristic detection of a single nozzle; installing a nozzle to be detected on a test frame, connecting a water pipe of a water supply system into the nozzle and providing working water pressure to enable the water pipe to spray water mist, adopting a camera to pick up images and inputting the images into a computer to calculate and obtain the size of an atomization cone angle of a water mist flow field of the nozzle, comparing the size of the atomization cone angle of the nozzle with a preset value, and judging that the quality of the nozzle does not meet the requirements if the size of the atomization cone angle of the nozzle does not meet the preset value; if the spray cone angle of the nozzle meets the requirement, detecting the particle size distribution range of the spray flow field of the nozzle by using a particle size analyzer, obtaining the Sott average particle size, comparing the Sott average particle size of the nozzle with a preset value, if the Sott average particle size of the nozzle does not meet the preset value, judging that the quality of the nozzle does not meet the requirement, and if the Sott average particle size of the nozzle meets the requirement, executing the next step;

2) completing the atomization characteristic detection of a single nucleon; installing a nuclear device to be detected on a test jig, respectively connecting a water pipe of a water supply system and an air pipe of an air supply system into the nuclear device, providing working water pressure and air pressure to enable the nuclear device to spray water mist, adopting a camera to pick up images and inputting the images into a computer to calculate to obtain the size of an atomizing cone angle of a water mist flow field of the nuclear device, comparing the size of the atomizing cone angle of the nuclear device with a preset value, and judging that the quality of the nuclear device does not conform to the preset value if the requirements are not met; if the atomization cone angle of the nuclear device meets the requirement, detecting the particle size distribution range of the water mist flow field of the nuclear device by a particle size analyzer, obtaining the Sott average particle size, comparing the Sott average particle size of the nuclear device with a preset value, if the Sott average particle size of the nuclear device does not meet the preset value, judging that the quality of the nuclear device does not meet the requirement, and if the Sott average particle size of the nuclear device meets the requirement, executing the next step;

3) installing the nozzles and the nuclei meeting the detection requirements in the first step and the second step on a test frame in parallel according to the spacing requirements, connecting the nozzles and the nuclei into a common water supply system, and connecting the nuclei into an air supply system, so that the nozzles and the nuclei jointly spray water mist under the conditions of working water pressure and working air pressure, and forming a coupling water mist flow field; and detecting the particle size distribution condition of the coupling water mist flow field by using a particle size analyzer, and if the particle size distribution range of the coupling water mist flow field is detected to be larger than the maximum value of the particle size distribution range of the single nucleon device and is smaller than the maximum value of the particle size distribution range of the single nozzle, judging that the nozzle and the nucleon device meet the matching requirement.

Thus, whether the performance of the single nozzle and the nuclear device is qualified or not and whether the coupling matching effect is qualified or not can be judged better.

Further, the number of nozzles may be adjusted to one or two for respective detection in the third step.

Therefore, one nozzle is matched with one nuclear device in part of the snow making machine, and two nozzles are matched with the nuclear device in part of the snow making machine, so that the matched snow making effect under two different conditions can be conveniently detected.

Further, during the third step of detection, the mutual inclination angles between the nozzle and the nuclear device can be sequentially adjusted, detection is performed, the condition that the particle size distribution range of the coupling water mist flow field is the minimum is selected as the optimal value in the inclination angles meeting the requirements, and the corresponding inclination angle is recorded.

Therefore, because the nozzles and the nucleon devices in part of the snow making machine are in inclined fit, when the particle size distribution range of the coupling water mist flow field is small, the made snowflakes are more uniform, and the snow making quality is more stable and reliable. Therefore, the method can test the optimal inclination angle between the nozzle and the nuclear device, and provides a basis for product design.

Further, during the third step, the front-back difference between the nozzle and the nuclear reactor can be adjusted in sequence, detection is performed, the condition that the particle size distribution range of the coupling water mist flow field is the minimum is selected as the optimal value in the front-back difference meeting the requirements, and the corresponding front-back difference is recorded.

Therefore, because the positions of the nozzles and the nucleon devices in part of the snow making machines are different from each other, when the particle size distribution range of the coupling water mist flow field is small, the made snowflakes are more uniform, and the snow making quality is more stable and reliable. Therefore, the mode can test the optimal front-back dislocation distance between the nozzle and the nuclear device, and provides a basis for product design.

In conclusion, the invention has the advantages that the atomization effect and the matching effect of the atomization component of the snow making machine can be tested more conveniently and rapidly, so that the product development improvement and the product quality inspection judgment can be realized.

Thus, when the test device is used for product design test, the inclined matching angle of the optimal atomization effect between the nozzle and the nuclear device can be detected. When the device is used for detecting the product quality, the actual installation angle between the nozzle and the nuclear device can be better simulated for detection, and the product quality can be more accurately reflected.

Therefore, based on the device, the invention actually discloses a design method of an atomization component of the snow making machine, namely after determining the respective model sizes of the nozzle and the nuclear device (the respective model sizes of the nozzle and the nuclear device can be correspondingly determined according to the model size of the snow making machine per se according to experience), the nozzle and the nuclear device are parallelly installed together and connected into a water supply system and a gas supply system, the working condition of the water supply system and the gas supply system is simulated for testing, the deviation angle size between the nozzle and the nuclear device is correspondingly adjusted (can be adjusted according to the size of 1-3 degrees each time) in each test, the coupled atomization flow field condition is detected and recorded, and when the particle size distribution range of the coupled water mist flow field is the minimum, the installation angle size between the nozzle and the nuclear device is the optimal matching design angle size of the nozzle and the nuclear device of the model. Thus, the snowflake making machine obtained by the design method can make snowflake effects with the most uniform and stable particle size and the highest efficiency, and can obtain the best snowflake making effect.

Specifically, referring to fig. 2, the nozzle interface adjusting mechanism in this embodiment further includes a pressure-welding block 26, an edge portion of the pressure-welding block 26 is detachably fixed at the lower end of the nozzle module by screws, an opening is provided at a middle position of the pressure-welding block 26 facing an opening at the lower end of the inner cavity of the nozzle module, an outer drum of the opening of the pressure-welding block 26 and the opening at the lower end of the inner cavity of the nozzle module integrally forms an integrally circular mounting cavity in the left-right direction (i.e., the direction of the vertical plane where the nuclear reactor and the nozzle are located after the nuclear reactor is mounted), an outer drum of the outer surface of the mounting sleeve 25 is in a matching circular shape in the left-right direction, the mounting sleeve 25 is pressed and fixed in the mounting cavity, and the lower end of the mounting sleeve has a section exposed out of the pressure-welding block.

Like this, because installation cavity and installation cover surface all are the circular and installation cover lower extreme that match have one section to expose in the part of crimping piece, so after loosening the screw, can rotate the direction of installation cover, adjust inclination, then rely on the screw to compress tightly fixedly again. Therefore, the adjusting device can conveniently and quickly adjust the installation angle between the nozzle and the nuclear device, and has the advantages of simple structure, quick, convenient and reliable adjustment and the like.

Wherein, the outer surface of the mounting sleeve 25 and/or the inner surface of the mounting cavity is provided with an elastic material layer.

Therefore, sealing can be better realized, and the pressing and fixing effects on the mounting sleeve can be guaranteed.

As another practical structure form of the nozzle interface adjusting mechanism, referring to fig. 4, the upper and lower ends of the mounting sleeve 25 (the mounting sleeve of the present embodiment structure may be a straight cylinder for convenient processing) are connected with the nozzle module by using a flexible sealing material 27, and the periphery of the mounting sleeve is made to enclose a flexible deformable adjusting area 27, the adjusting area 28 is filled with magnetorheological fluid, and the left and right ends of the adjusting area 28 (i.e. the direction of the vertical plane where the nuclear instrument and the nozzle are located after the nuclear instrument is mounted) are further provided with electromagnets 29.

Thus, when installed therein, the magnetorheological fluid should be within the range of the action of the magnetic field of the electromagnet. When the electromagnet is powered off, the magnetorheological fluid is fluid, and the deflection angle of the installation sleeve in the left and right directions can be freely adjusted; after the angle of the mounting sleeve is adjusted in place, the electromagnet is switched on, and the magnetorheological fluid becomes hard under the action of the magnetic field to fix the angle of the mounting sleeve. Therefore, the deviation angle between the installed nozzle and the nuclear device can be conveniently and quickly adjusted by utilizing the characteristics of the magnetorheological fluid. Meanwhile, a section of flexible sealing material is connected between the upper end of the mounting sleeve and the nozzle module in the structure; therefore, the structure can also realize the adjustment of the mounting sleeve in the height direction and the angle difference in other directions according to the requirement. Therefore, when the device is used for quality detection, the actual conditions of the angle deviation (including the angle deviation in the horizontal direction and the angle deviation in the vertical direction) and the height deviation between the nozzles and the nuclear instrument of different product types can be better simulated; greatly improving the quality detection effect. When the device is used for designing an atomization component product, the device can also adjust the nozzle and the nuclear device to be in different angle deviations in the vertical direction and the horizontal direction and to be in different distance conditions in the height direction in each test, atomization flow field data after coupling in different conditions are detected and recorded, and when the particle size distribution range of the coupling water mist flow field is the minimum, the size of the installation angle and the height difference (namely the difference in the front-back direction) between the nozzle and the nuclear device are the optimal matching position of the nozzle and the nuclear device of the type. This results in a relative position between the nozzle and the nucleator that produces the maximum snowmaking effect (including data on the magnitude of the horizontal declination angle, the magnitude of the vertical declination angle, and the magnitude of the height-wise distance). Ensuring that the designed snowmaker has the best snowmaking effect.
