[0024] Through the setting of the above structure, first adjust the second telescopic rods 9 on both sides to a suitable and identical length, and then simultaneously attach the positioning rollers 91 on both sides to the wall to ensure that the second telescopic rods 9 remain perpendicular to the wall. That is, at this time, the detection end of the optical rangefinder 44 will be perpendicular and equidistant to the wall at any work position, thereby ensuring the accuracy of flatness detection.

[0026] Through the arrangement of the above structure, the lifting motor 32 is turned on to drive the vertical screw rod 31 to rotate, and when the lifting plate 4 moves upward by one detection station, the lifting motor 32 stops, and then the translation motor 45 is operated to drive the horizontal screw rod 42 to rotate, so that the translation sleeve 43 carries the optical rangefinder 44 to perform flatness detection on the wall surface in the horizontal area of ​​this station. When the detection of this station is completed, the lifting motor 32 continues to drive the lifting plate 4 to move upward by one station, and then performs flatness detection on the wall surface in the horizontal area of ​​this station. This reciprocating process realizes comprehensive detection of the wall, effectively improving the detection efficiency.

[0027] Reference Figures 1-8 , wherein, the air guide portion includes a piston plate 61, the piston plate 61 is slidably connected to the piston box 6, and both sides of the piston plate 61 are fixedly connected to the inner magnetic plate 611, the outer wall of the translation sleeve 43 is fixedly connected to the outer magnetic plate 62, the outer magnetic plate 62 and the inner magnetic plate 611 are parallel to each other and magnetically attracted to each other, a cleaning brush 52 is fixedly connected to the upper part of the side wall of the cleaning plate 5, a dust extraction hole 53 is opened at the lower part of the side wall of the cleaning plate 5, the dust extraction hole 53 is connected to the inner cavity of the cleaning plate 5, a dust suction groove 54 is opened in the first telescopic sleeve 51, and the suction The dust trough 54 is connected to the inner cavity of the cleaning plate 5, and an exhaust pipe 63 is fixed and connected to the side wall of the piston box 6. The other end of the exhaust pipe 63 is connected to the inner cavity of the dust suction trough 54, and a one-way valve is provided in the exhaust pipe 63; the bottom of the movable seat 1 is fixedly connected to a counterweight box 7, the counterweight box 7 is loaded with clean water, and an exhaust pipe 71 is fixedly connected to the counterweight box 7, the input end of the exhaust pipe 71 is connected to the inner cavity of the piston box 6, and the output end of the exhaust pipe 71 passes through below the clean water liquid level, and a one-way valve is provided in the exhaust pipe 71.

[0028] It should be noted that the one-way valve in the exhaust pipe 63 can only allow the airflow around the cleaning plate 5 to enter the piston box 6; the one-way valve in the exhaust pipe 71 can only allow the gas in the piston box 6 to enter the counterweight box 7.

[0029] Through the arrangement of the above structure, first, the cleaning brush 52 is attached to the wall by adjusting the first telescopic sleeve 51, and then during the rising process of the lifting plate 4, the cleaning brush 52 will scrape the wall to remove the floating dust and impurities attached to the wall, ensuring the cleanliness of the wall to be tested, reducing the influence of dust and impurities on the test results, and improving the accuracy of the test; and in the process of movement of the translation sleeve 43, the magnetic attraction between the outer magnetic plate 62 and the inner magnetic plate 611 will cause the inner magnetic plate 611 to pull the piston plate 61 to slide in the piston box 6, and in this process, negative pressure suction and positive pressure thrust will be generated in the inner cavities on both sides of the piston box 6 at the same time. First, the negative pressure suction will open the one-way valve in the exhaust pipe 63 The negative pressure is transmitted along the exhaust pipe 63 and the dust suction groove 54 to the dust suction groove 54, and the air flow around the cleaning plate 5 is sucked away along the dust suction hole 53, that is, the floating dust particles scraped down by the cleaning brush 52 are sucked away, and finally enter the piston box 6 with the air flow. As the translation sleeve 43 slides back and forth, the negative pressure suction force in the piston box 6 will be converted into positive pressure thrust, and the one-way valve in the exhaust pipe 71 will be opened. At this time, the air flow carrying floating dust sucked into the piston box 6 will be pushed along the exhaust pipe 71 to below the clean water level in the counterweight box 7, and then the gas will float to the counterweight box 7, and the floating dust will be retained in the water body, thereby realizing the interception and collection of floating dust, and effectively improving the air environment quality in the detection area.

[0030] Reference Figure 2-Figure 8 , wherein the top of the moving seat 1 is located just above each set of moving wheels 2 and is fixedly connected to an inflatable cylinder 8, a telescopic rod 81 is slidably connected to the inflatable cylinder 8, a locking groove 21 is opened on the top of the moving wheel 2, the bottom end of the telescopic rod 81 passes through the locking groove 21 and is fixedly connected to a locking arc plate 22, a first spring 82 is fixedly connected between the telescopic rod 81 and the inner wall of the inflatable cylinder 8, the two sets of inflatable cylinders 8 located on the short side of the moving seat 1 are connected by a first conduit 83, and the two sets of inflatable cylinders located on the long side of the moving seat 1 are connected The cylinders 8 are connected through a second conduit 84. The top of the inner cavity of the counterweight box 7 is fixed and connected with an inflation tube 85. The other end of the inflation tube 85 is connected with the second conduit 84, and the inflation tube 85 is fixed and connected with a pressure relief tube 86. A solenoid valve is provided in the pressure relief tube 86. The solenoid valve of the pressure relief tube 86 can be opened after the detection is completed to discharge the high-pressure airflow in each group of inflation cylinders 8, and under the rebound action of the first spring 82, the locking effect on the moving wheel 2 is released to facilitate the replacement of the detection area.

[0031] Through the setting of the above structure, the gas that continuously enters the counterweight box 7 will enter each group of inflation cylinders 8 along the inflation tube 85, the second conduit 84 and the first conduit 83, so that the air pressure in the inflation cylinder 8 continues to increase, and finally pushes the telescopic rod 81 to slide downward, so that the locking arc plate 22 fits onto the moving wheel 2, realizing the locking of the moving wheel 2, improving the overall stability of the moving base 1 during the detection process, and thus ensuring the accuracy of the detection.

[0032] Reference Figure 3 、 Figure 4 、 Figure 6 and Figure 8 , wherein a backflush pipe 87 is fixedly connected to the top of the mounting plate of the optical rangefinder 44 , the output end of the backflush pipe 87 is directed toward the detection end of the optical rangefinder 44 , the other end of the backflush pipe 87 is connected to the second conduit 84 , and a pressure valve is provided on the backflush pipe 87 .

[0033] Through the arrangement of the above structure, when the air pressure in the second conduit 84 continues to increase and exceeds the opening threshold of the pressure valve, the pressure valve will be pushed open and enter the back-blowing pipe 87, so that the air flow blows along the back-blowing pipe 87 toward the detection end of the optical rangefinder 44, thereby effectively cleaning the detection end of the optical rangefinder 44, avoiding the adhesion of dust and impurities, improving the clarity of the detection of the optical rangefinder 44, and thus ensuring the accuracy of the final detection.

[0034] Example 2: Reference Figures 1-8 , which is basically the same as the first embodiment, on the basis of the first embodiment, a method for detecting the flatness of the interior wall of a building is proposed, and the steps are as follows: Step 1: Adjust the optical rangefinder 44 to a position perpendicular to the wall to be measured; Step 2: driving the optical rangefinder 44 to slide in the horizontal and vertical directions to complete the comprehensive detection operation; Step 3: During the inspection process, clean the wall surface that needs to be inspected later; Step 4: During the detection process, the moving wheel 2 is locked; Step 5: During the detection process, the detection end of the optical rangefinder 44 is cleaned.

[0035] Reference Figures 1-8In the present invention, when in use, first adjust the second telescopic sleeves 9 on both sides to an appropriate and identical length, then simultaneously attach the positioning rollers 91 on both sides to the wall surface, ensuring that the second telescopic sleeves 9 are perpendicular to the wall surface, that is, the detection end of the optical rangefinder 44 is perpendicular to the wall surface and equidistant at any position at this time, thereby ensuring the accuracy of the flatness detection, and by adjusting the first telescopic sleeve 51, the cleaning brush 52 is attached to the wall surface; next, start the lifting motor 32 to drive the vertical screw rod 31 to rotate, and when the lifting plate 4 moves upward by one detection position, the lifting motor 32 stops, and then the translation motor 45 is operated to drive the horizontal screw rod 42 to rotate, so that the translation sleeve 43 carries the optical rangefinder 44 to perform flatness detection on the wall surface in the horizontal area of ​​this position. After the detection of this position is completed, the lifting motor 32 continues to drive the lifting plate 4 to move upward by one position, and then performs flatness detection on the wall surface in the horizontal area of ​​this position again, and so on and so forth, thereby achieving comprehensive detection of the wall, effectively improving the detection efficiency.

[0036] During the rising process of the lifting plate 4, the cleaning brush 52 will scrape the wall surface and remove the floating dust and impurities attached to the wall surface, ensuring the cleanliness of the wall surface to be tested, thereby improving the accuracy of the detection. During the movement of the translation sleeve 43, the magnetic attraction between the outer magnetic plate 62 and the inner magnetic plate 611 will cause the inner magnetic plate 611 to pull the piston plate 61 to slide in the piston box 6. In this process, negative pressure suction and positive pressure thrust will be generated in the inner cavities on both sides of the piston box 6 at the same time. First, the negative pressure suction will open the one-way valve in the exhaust pipe 63, and the negative pressure will be transmitted to the dust suction groove 54 along the exhaust pipe 63 and the dust suction groove 54. The airflow around the cleaning plate 5 is sucked away along the dust extraction hole 53, that is, the floating dust particles scraped down by the cleaning brush 52 are sucked away, and finally enter the piston box 6 with the airflow. As the translation sleeve 43 slides back and forth, the negative pressure suction in the piston box 6 is converted into positive pressure thrust, and the one-way valve in the exhaust pipe 71 is opened. At this time, the airflow carrying floating dust sucked into the piston box 6 will be pushed along the exhaust pipe 71 to below the clean water level in the counterweight box 7, and then the gas will float up to the counterweight box 7, while the floating dust will be retained in the water body, thereby realizing the interception and collection of floating dust, and effectively improving the air environment quality in the detection area.

[0037] In addition, the gas that continuously enters the counterweight box 7 will enter each group of inflation cylinders 8 along the inflation tube 85, the second conduit 84 and the first conduit 83, so that the air pressure in the inflation cylinder 8 continues to increase, and finally pushes the telescopic rod 81 to slide downward, so that the locking arc plate 22 fits onto the moving wheel 2, thereby locking the moving wheel 2, improving the overall stability of the moving seat 1 during the detection process, and thus ensuring the accuracy of the detection. When the air pressure continues to increase and exceeds the opening threshold of the pressure valve, it will push open the pressure valve and enter the backflush pipe 87, so that the air flow blows along the backflush pipe 87 toward the detection end of the optical rangefinder 44, thereby effectively cleaning the detection end of the optical rangefinder 44, avoiding the adhesion of dust and impurities, and improving the clarity of the detection of the optical rangefinder 44, thereby ensuring the accuracy of the final detection.
