When the moving block 11 continues to move upward, it drives the first mounting plate 13, the first electric push rod 14 and the first cleaning block 15 to move to the top of the mounting block 8 through the movable opening at the top of the mounting block 8.

When the cleaning is completed, the first mounting plate 13, the first electric push rod 14 and the first cleaning block 15 are moved to the inside of the mounting block 8, and then moved to the movable opening through the electric telescopic plate 26. The magnetic connection of the magnetic block 27 fixes the telescopic end of the electric telescopic plate 26 at the movable opening to block the top of the mounting block 8, so as to prevent rainwater from dripping into the inside of the mounting block 8, affecting the movement of the moving block 11, and making it inconvenient for the first cleaning block 15 and the second cleaning block 19 to clean.

[0037] like Figures 6 to 8 As shown, dust collecting boxes 28 are fixedly installed on both sides of the second electric push rod 17 and on one side of the second mounting plate 16, two dust suction pumps are arranged on one side of the dust collecting box 28, and two dust collecting pipes 29 are fixedly installed on one side of the dust suction pump.

[0039] like Figures 6 to 8 As shown, a water tank 30 is fixedly installed on the top of the fixed plate 7 and on one side of the top of the mounting block 8, a collecting port is opened on the top of the water tank 30, a filter plate 31 is arranged inside the water tank 30, two connecting pipes 32 are fixedly installed on one side of the bottom end of the water tank 30, a delivery pipe 33 is fixedly installed on one side of the top of the two connecting pipes 32, a nozzle 34 is fixedly installed on one side of the delivery pipe 33 and the bottom of the connecting pipe 32, a first control valve is fixedly installed on one end of the two connecting pipes 32 near the water tank 30, one end of the two connecting pipes 32 passes through one side of the mounting block 8 and extends downward to the inside of the chute, and the bottom end thereof passes through the left slider 12 and extends to one side of the second cleaning block 19, a second control valve is arranged on one side of the two connecting pipes 32 near the second cleaning block 19, the delivery pipe 33 is located on one side of the first cleaning block 15 and it is located on the top of the moving block 11, and the two nozzles 34 are respectively located on one side of the first cleaning block 15 and the second cleaning block 19

[0040] The rainwater is collected into the water storage tank 30 through the collecting port for storage, and filtered through the filter plate 31 to filter out large particles of impurities in the rainwater, and then the first control valve is started to transport the filtered water through the connecting pipe 32, and the water is directed to the first cleaning block 15 through the nozzle 34 through the conveying pipe 33, and the first cleaning block 15 after cleaning is rinsed, so that the impurities and dust adhering to the first cleaning block 15 are cleaned, and then the second control valve is started to transport the water inside the connecting pipe 32 to the nozzle 34 at the bottom of the connecting pipe 32, and the filtered rainwater is sprayed on the second cleaning block 19 to clean the second cleaning block 19, so that the first cleaning block 15 and the second cleaning block 19 are cleaned after cleaning the lens 5, which is convenient for the subsequent cleaning of the first cleaning block 15 and the second cleaning block 19, thereby improving the use effect of the first cleaning block 15 and the second cleaning block 19, thereby further improving the use effect of the monitoring body 3 and the three-dimensional laser scanning device 4.

[0041] Working principle: When the monitoring body 3 is used in a humid or cold environment, the heating block 21 inside the groove is started to heat, and the fan 22 is started to rotate, so that the hot air generated by the heating block 21 is blown to the inside of the lens 5. The fan 22 makes it easy to evenly distribute the hot air inside the lens 5 to heat the inside of the lens 5, and the air circulation inside and outside the lens 5 of the monitoring body 3 is maintained through the through hole 6, which can avoid excessive temperature difference between the inside and outside of the lens 5, thereby reducing the possibility of water vapor condensation, and the air is filtered through the filter 20, so that impurities and dust in the air are removed.

When the slider 12 moves to the bottom of the slide slot, the moving block 11 moves to the movable opening at the bottom of the mounting block 8, and the second mounting plate 16 drives the second electric push rod 17, the connecting block 18 and the second cleaning block 19 to move to the side of the lens 5, and correspond to the lens 5. By starting the second electric push rod 17 to push The movable connecting block 18 and the second cleaning block 19 are moved to the lens 5, so that the second cleaning block 19 is fitted with the lens 5, and the threaded rod 10 is driven to rotate by the motor 9, so that the movable block 11 drives the second mounting plate 16 and the second electric push rod 17, the connecting block 18, and the second cleaning block 19 to move up and down, so that the second cleaning block 19 can clean the lens 5, clean the dust, raindrops, and frost adhered to the outside of the lens 5, so that the outside and the inside of the lens 5 are cleaned.

When the second electric push rods 17 push the connecting block 18 and the second cleaning block 19 to fit the lens 5, the dust collecting pipe 29 is stretched, and the dust collecting pipe 29 horizontally arranged above corresponds to the two through holes 6 above the lens 5, and the dust collecting pipe 29 inclined below corresponds to the two through holes 6 below the lens 5. The dust suction pump is started so that the dust collecting pipe 29 cleans the dust and impurities adhered to the filter screen 20 inside the through hole 6, and collects them through the dust collecting box 28 to prevent excessive accumulation of impurities and dust on the filter screen 20, which affects the air circulation inside the through hole 6 and the lens 5, and is not conducive to the defrosting and defogging effect of the lens 5.

[0042] When the lens 5 is cleaned, the second electric push rod 17 drives the connecting block 18 and the second cleaning block 19 to move to the bottom of the movable opening, and then the motor 9 drives the threaded rod 10 to rotate, so that the moving block 11 drives the slider 12 to move upward, so that the second mounting plate 16 drives the second electric push rod 17, the connecting block 18 and the second cleaning block 19 to move to the inside of the mounting block 8. When the moving block 11 continues to move upward, it drives the first mounting plate 13, the first electric push rod 14 and the first cleaning block 15 to move to the top of the mounting block 8 through the movable opening at the top of the mounting block 8.
