The appearances of the phrase "in one embodiment" in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments.

Example 1

Referring to fig. 1 to 5, the present embodiment provides an automatically adjustable optical cable cross-connecting cabinet, including a cabinet 100 and an adjusting assembly 200, wherein the top of the cabinet 100 includes a top plate 101, the top plate 101 is provided with a heat dissipation hole 101a, and the heat dissipation hole 101a may also be disposed on a side panel of the cabinet 100; the adjusting assembly 200 comprises a containing part 201 installed on the lower side surface of the top plate 101, a central shaft 202 located in the containing part 201, and a cover plate 203 connected with the central shaft 202, wherein the cover plate 203 covers the heat dissipation holes 101 a; the accommodating part 201 is cylindrical, and the central shaft 202, the cover plate 203, the accommodating part 201 and the heat dissipation holes 101a are all coaxially arranged; when the temperature inside the cabinet 100 is too high, the internal gas pressure increases, and the cover plate 203 is pushed open, so that the internal air with too high temperature can be discharged.

Further, a temperature sensor 102 is arranged in the box 100, the temperature sensor 102 is connected to a processor 103, the processor 103 is a CPU and is used for determining and analyzing the temperature of the box 100, the processor 103 is connected to a driving module 104, the driving module 104 is a micro motor, information of the processor 103 is transmitted to a storage module 105 for storage, the driving module 104 is installed on the top plate 101 and is connected with a first gear 106, the processor 103 controls the on/off of the driving module 104, and the driving module 104 drives the first gear 106 to operate.

The outer end face of the heat dissipation hole 101a is circumferentially provided with a groove 101b, the groove 101b is arc-shaped and concentric with the heat dissipation hole 101a, the bottom of the groove 101b and the top plate 101 form a slope 101c, the cover plate 203 is provided with an adjusting pin 203a, and the adjusting pin 203a can be embedded into the groove 101 b. When long-time heat dissipation is needed, the cover plate 203 is rotated to enable the adjusting pin 203a to slide out of the groove 101b and abut against the surface of the top plate 101, namely, a gap between the cover plate 203 and the top plate 101 can be opened, namely, the heat dissipation holes 101a can dissipate heat; accordingly, the cover plate 203 is rotated to insert the adjusting pin 203a into the groove 101b, thereby performing an automatic heat dissipation and pressure discharge process.

Preferably, the cover plate 203 is provided with the second gear 203b along one circle along the circumference, the second gear 203b is meshed with the first gear 106, the tooth width of the first gear 106 is larger than the sum of the tooth width of the second gear 203b and the height of the adjusting pin 203a, and because the second gear 203b is meshed with the first gear 106, manual rotation of the cover plate 203 is not needed; specifically, when heat dissipation is not needed in the box body, the cover plate 203 covers the heat dissipation hole 101a, and when the internal temperature rises and the pressure is too high, the cover plate 203 is automatically pushed open to perform air exhaust and heat dissipation; however, if the temperature inside the box body is increased all the time, the cover plate 203 needs to be opened frequently, and then the temperature sensor 102 transmits the temperature information to the processor 103, and after the temperature information is judged by the processor 103, the driving module 104 is opened to drive the first gear 106 to rotate, so as to drive the cover plate 203 to rotate, and at this time, the adjusting pin 203a slides out of the groove 101b and butts against the surface of the top plate 101, so as to open the gap between the cover plate 203 and the top plate 101, that is, the heat dissipation hole 101a can dissipate heat.

It should be noted that, when the processor 103 determines that the temperature in the box 100 exceeds x degrees celsius for n minutes continuously, the processor 103 activates the driving module 104 to perform long-term heat dissipation, and when the processor 103 determines that the temperature in the box 100 has decreased to a safe range, the driving module 104 is activated to close the gap between the cover 203 and the top plate 101.

Further, the accommodating part 201 comprises a cylinder 201a and a sealing plate 201b hermetically connected with one end of the cylinder 201a, the cylinder 201a is divided into an air inlet part 201a-1 connected with the top plate 101 and an accommodating part 201a-2 connected with the sealing plate 201b, the air inlet part 201a-1 is provided with an air inlet 201c, the air inlet part 201a-1 is connected with the top plate 101 through welding or bolts, one end of a central shaft 202 is connected with a piston 204, the piston 204 is located in the accommodating part 201a-2, a one-way ventilation assembly 300 is installed on the piston 204, and the one-way ventilation assembly 300 is a one-way valve; a partition plate 205 is installed between the air inlet 201a-1 and the accommodating part 201a-2 in the accommodating part 201, a first through hole 205a is formed in the center of the partition plate 205, a second through hole 205b is formed in the partition plate 205 along the circumference, and the central shaft 202 penetrates through the first through hole 205a, namely, one end of the central shaft 202 is connected with the piston 204, and the other end of the central shaft is connected with the cover plate 203.

Further, a first elastic member 206 is disposed between the partition 205 and the piston 204, the first elastic member 206 is preferably a pressure spring, a gas space M is formed between the piston 204 and the sealing plate 201b, and the volume of the gas space M changes when the piston 204 moves in the accommodating portion 201 a-2.

Further, the central shaft 202 is provided with a discharge hole 202a, and the discharge hole 202a has a flow rate smaller than that of the one-way vent assembly 300, wherein one end of the discharge hole 202a opens into the air space M and the other end opens to the outside of the air space M.

Preferably, a screw hole 202b communicated with the air release hole 202a is formed in one end, connected with the cover plate 203, of the central shaft 202, an adjusting sealing bolt 207 is arranged in the screw hole 202b, an adjusting cone 207a is arranged at one end of the adjusting sealing bolt 207, the adjusting cone 207a is conical, the diameter of the bottom surface of the adjusting cone 207a is not larger than that of the air release hole 202a, and the adjusting cone 207a can be embedded into the air release hole 202 a. Therefore, the adjusting sealing bolt 207 can adjust the depth of the adjusting cone 207a into the air release hole 202a, and further adjust the flow rate of the air release hole 202a, and when the adjusting cone 207a is deeper into the air release hole 202a, the smaller the space between the adjusting cone 207a and the air release hole 202a is, the smaller the flow rate can pass through.

The implementation mode and the working principle of the embodiment are as follows: when the temperature inside the box 100 is normal, the gas pressure is normal, and at this time, the cover plate 203 covers the heat dissipation holes 101a without heat dissipation, and meanwhile, foreign matters such as external dust can be prevented from entering the box 100; when the temperature in the case 100 rises, the pressure inside increases under the sealed condition, and when the pressure in the case 100 is greater than the elastic force of the first elastic member 206, the first elastic member 206 is compressed and the cover plate 203 is lifted, the heat dissipation hole 101a is opened, and at this time, the piston 204 moves upward, the volume of the air space M becomes larger, the air enters the air space M through the one-way ventilation assembly 300, when the heat dissipation hole 101a is opened, the internal overheated air is exhausted, when the air having an excessively high temperature inside the cabinet 100 is exhausted, in order to prevent the temperature inside the cabinet 100 from being rapidly increased again, the cover plate 203 is slowly dropped, because the gas in the gas space M can only be discharged through the discharge hole 202a, and the flow rate of the discharge hole 202a is much smaller than that of the one-way venting assembly 300, the piston 204 will be slowly reset, meanwhile, the reset time of the cover plate 203 can be adjusted by adjusting the sealing bolt 207 according to actual conditions. It should be noted that the first elastic member 206 has a small elastic force, so that it can ensure that the cover plate 203 is lifted up once the temperature inside the cabinet 100 rises.

Example 2

Referring to fig. 1 to 7, a second embodiment of the present invention is based on the previous embodiment, and is different from the previous embodiment in that: the sealing plate 201b is provided with an exhaust fan 400, the inner side surface of the top plate 101 is also provided with a guide pipe 500, and the accommodating part 201 is positioned in the guide pipe 500. The exhaust fan 400 is fixed on the sealing plate 201b, and when heat is dissipated, the exhaust fan 400 is turned on to accelerate heat dissipation and exhaust, and the flow guide pipe 500 mainly plays a role in flow guide.

Further, two conductive pieces 205c are disposed outside the first through hole 205a, the conductive pieces 205c are conductors, both the conductive pieces 205c are in contact with the surface of the central shaft 202, and the conductive pieces 205c can be attached to the surface of the central shaft 202 by a spring. The two conductive blocks 205c are connected to the exhaust fan 400 and the external power supply 600, respectively, by wires; an annular groove 202d is formed in the surface of one end of the central shaft 202 connected to the piston 204, and a conductive ring 208 is sleeved on the surface of the annular groove 202d, that is, the central shaft 202 itself is not conductive, and the conductive ring 208 is a conductor, and it should be noted that the height of the conductive ring 208 is not greater than the distance between the conductive block 205c and the sealing plate 201 b. That is, when the internal pressure or temperature of the box 100 is normal, the cover plate 203 covers the heat dissipation holes 101a, the central shaft 202 is located at a relatively lower position, the two conductive blocks 205c are in contact with the non-conductive central shaft 202, the circuit of the exhaust fan 400 is open and not powered, when the internal pressure of the box 100 increases or the temperature increases, the cover plate 203 moves upward, that is, the central shaft 202 moves upward, and at this time, the two conductive blocks 205c are in contact with the conductive ring 208 at the lower end of the central shaft 202 to form a passage for opening the exhaust fan 400 to operate.

It should be noted that, a plurality of mounting holes 204b are provided on the piston 204, two ends of the mounting hole 204b extend towards the axis to form a limiting boss 204c, the one-way ventilation assembly 300 is located in the mounting hole 204b, the one-way ventilation assembly 300 includes a movable partition plate 301 close to the partition plate 205 and a second elastic member 302 connected with the movable partition plate 301, and the diameter of the movable partition plate 301 is greater than the diameter of the limiting boss 204c and smaller than the diameter of the mounting hole 204 b. Accordingly, the gas in the case 100 can enter into the gas space M through the unidirectional ventilation assembly 300, and the gas in the gas space M can be discharged only through the discharge hole 202 a.

Preferably, the shape of the cover plate 203 is a cone, that is, the cover plate 203 has an umbrella-shaped structure covering the heat dissipation holes 101a, so as to facilitate the gas to lift the cover plate 203.
