Some embodiments, the present application provides a flatness detecting apparatus, referring to fig. 1, including: at least two movable support, flexible pipe 140, liquid level detection subassembly, treater, each movable support includes support main part 110 and stock solution pipe 120, the bottom of each support main part 110 is used for contacting with the face 130 that awaits measuring, store liquid 121 in each stock solution pipe 120, flexible pipe 140 is used for communicating each other between all stock solution pipes 120, liquid level detection subassembly is arranged in detecting the height of liquid 121 liquid level in each stock solution pipe 120, liquid level detection subassembly is connected to the treater, the treater calculates the roughness according to the height data of liquid level.

Illustrative embodiments, the levelness detection principle of the present application will be described in detail below by taking a levelness detection apparatus having two movable brackets as an example. When the surface 130 to be detected is a horizontal ground, the detection device is vertically placed on the surface 130 to be detected, the movable support can freely move in the vertical direction in the detection device, and when the surface 130 to be detected has a protrusion or a recess, the support main body 110 can freely move upwards or downwards when contacting the surface 130 to be detected, so that the whole movable support is driven to move, and the corresponding liquid storage tube 120 can also move. The support main body 110 and the liquid storage tube 120 can be fixedly connected, or can be connected through a flexible connecting piece or a gear or other transmission mechanism, and the corresponding liquid storage tube 120 can be moved only by the movement of the support main body 110. Because liquid 121 is stored in liquid storage tubes 120, and liquid storage tubes 120 are connected through flexible tube 140, a communicating vessel structure is formed between two liquid storage tubes 120, and the liquid level heights in two liquid storage tubes 120 are always in the same horizontal plane. However, since the liquid level of the liquid storage tube 120 is different, the relative height of the liquid level in the liquid storage tube 120 is also different, and the displacement change of the liquid storage tube 120 relative to the initial position can be obtained by calculation according to the height difference of the rising or falling of the liquid level and the parameters such as the diameter of the liquid storage tube 120, and the parameters such as the diameter of the liquid storage tube 120 are fixed parameters which are preset, so that the flatness of the surface to be measured 130 can be obtained only by detecting the height change of the liquid level.

The initial height of the liquid level in the liquid storage tube 120 can be the liquid level when the movable supports are all at the same level, or the specific position in the specific liquid storage tube 120 can be arbitrarily designated as the initial height, and only the corresponding change is needed during data processing.

The liquid level detecting assembly is used for detecting the liquid level in each liquid storage tube 120, and the detection mode can be selected at will. For example, the distance detecting sensor 151 is used, and the distance between the distance detecting sensor 151 and the liquid level is calculated according to the transmission speed and the transmission time of the signal by using the light wave or the sound wave which is reflected by the liquid level and is transmitted and received. The position of the distance detection sensor 151 is fixed in the detection device, and the length of the liquid storage tube 120 is known, so that the height of the liquid level in the liquid storage tube 120 can be calculated. Alternatively, the liquid 121 in the liquid storage tube 120 may be stained by using the image detection sensor 152, and the height information of the liquid level may be obtained by acquiring the image information of the side surface of the liquid storage tube 120 and performing image processing. The sensor detection type of the liquid level detection assembly can be set to be multiple, multiple sensors are used for detecting liquid level height information together, and the accuracy of detecting the liquid level height can be improved.

The liquid level detection assembly sends the detected liquid level height information to the processor in a wired or wireless communication mode, the processor processes the information according to a preset calculation program, and can output the height difference of each sampling point relative to the reference level height or process multiple groups of sampling data to obtain a detection result so as to quantitatively reflect the flatness of the surface to be detected 130.

Referring to fig. 2, any number of movable supports may be provided to increase the sampling density of the surface 130 to be measured. The arrangement mode of the movable supports can be selected at will. When all the movable supports are transversely arranged on the same straight line, the obtained flatness is the flatness of the transverse section on the plane of the surface 130 to be measured, the flatness of different transverse sections can be obtained by moving the flatness detection device in the longitudinal direction and sampling, and the obtained flatness of different transverse sections can only reflect the transverse flatness of the surface 130 to be measured, so that the flatness of the whole plane of the surface 130 to be measured cannot be obtained by correlating the flatness of different transverse sections. The flatness of a group of longitudinal sections can be detected simultaneously by arranging a movable support in the longitudinal direction of the surface 130 to be detected during movement, and the flatness of different transverse sections can be related, so that the flatness of the whole plane can be obtained. The liquid storage tube 120 of the longitudinal movable support can be communicated with the liquid storage tube 120 of the transverse movable support through the flexible tube 140 to jointly form a communicating device structure, or the liquid storage tube 120 can be arranged on the central movable support and communicated with the liquid storage tube 120 on the longitudinal movable support to form another independent communicating device, and the same technical effect can be achieved. The longitudinal movable support can also be arranged in a plurality of numbers so as to improve the accuracy of the measuring result.

In some embodiments, the flatness detecting apparatus further includes a displacement detecting module, the displacement detecting module is configured to detect a moving distance of the flatness detecting apparatus on the surface 130 to be measured, and the liquid level detecting assembly performs equal-interval sampling according to the moving distance. The displacement detection module can detect out the distance that roughness detection device removed for roughness detection device just gathers the liquid level information that liquid level detection subassembly gathered once after removing preset sampling distance, along with roughness detection device's removal, gathers the multiunit sampling result that obtains the equidistant. Sampling results obtained by sampling with the same interval distance are more uniform, and sampling distances of different sizes can be set according to different flatness detection requirements. The displacement detection module can be set as an existing sensor for detecting displacement by adopting light beams or a positioning system for detecting displacement, and can be set randomly according to actual needs.

In some embodiments, at least one of the holder main bodies 110 is provided with a roller 160 at a bottom end thereof, and the bottom end of each of the holder main bodies 110 is adapted to contact the surface 130 to be measured via the roller 160. Through setting up gyro wheel 160, reduce the frictional force between movable support and the face 130 that awaits measuring, conveniently carry out the roughness under the great scene of face 130 area that awaits measuring, like the condition such as road, square, airport runway and detect. In some other embodiments, a striker or the like may be provided on a smooth surface having a small area.

In some embodiments, the displacement detection module includes an encoder 170, the encoder 170 is connected to the rotating shaft of the roller 160, and the displacement detection module is configured to calculate a moving distance of the flatness detection apparatus on the surface 130 to be measured according to detection data of the encoder 170. The encoder 170 may be directly connected to the rotating shaft of the roller 160, or the rotation of the roller 160 is transmitted to the encoder 170 through a gear or a transmission chain, and the distance that the roller 160 moves on the surface 130 to be measured can be detected through the specific structure of the encoder 170 connected to the roller 160, the diameter of the roller 160, and other parameters, so as to complete the function of sampling at equal intervals.

In some embodiments, the liquid level detection assembly comprises at least two liquid level detection sensors, each liquid level detection sensor is disposed on each of the liquid storage tubes 120 and is used for detecting the level of the liquid 121 in each of the liquid storage tubes 120. When the distance between the liquid storage tubes 120 is relatively long, a liquid level height detection sensor is arranged at a corresponding position on each liquid storage tube 120 for accurately detecting the height of the liquid level. In some other embodiments, for example, in the case where different reservoirs 120 are relatively close to each other, one image sensor may be used to perform the function of detecting the liquid level of multiple reservoirs 120.

In some embodiments, the liquid level detection sensor includes: at least one of an ultrasonic ranging sensor, a laser ranging sensor, an infrared ranging sensor, a liquid level sensor and an image liquid level detection sensor. The liquid 121 with high reflectivity can be selected according to the detection principles of different sensors, or a floatable marker can be arranged on the liquid level, so that the position of the liquid level is more obvious. The liquid level sensor may employ liquid level detectors of different principles, such as a float ball type liquid level transmitter, a magnetic liquid level transmitter, a drop-in type liquid level transmitter, an electric inner float ball type liquid level transmitter, an electric float level transmitter, a capacitive type liquid level transmitter, a magnetostrictive liquid level transmitter, a servo liquid level transmitter, and the like.

The detecting frame 180 is provided with a height detecting component 181 for measuring the vertical distance between the detecting frame 180 and the surface 130 to be detected. Through the height that detection frame 180 and support main part 110 are fixed, and the distance to between the liquid storage pipe 120, can convert the height data that height detection subassembly 181 detected into liquid level height data through calculating, unified calculation when making things convenient for subsequent data processing.

Referring to fig. 4, when the flatness of the whole plane of the surface 130 to be detected needs to be detected, the movable bracket may not be arranged in the longitudinal direction, and the detecting frame 180 may be directly arranged in the longitudinal direction, so that the same technical effect may be achieved. In some other embodiments, the detecting frame 180 and the movable frame may be disposed in the longitudinal direction, and the number of the detecting frames and the movable frame may be set arbitrarily.
