[0026] Example 2:

[0027] Based on Embodiment 1, this utility model is as follows: Figures 1-3 As shown, a slider 15 is threadedly connected to the surface of a reciprocating lead screw 14, a movable frame 7 is fixedly mounted on the surface of the slider 15, a cleaning scraper 5 is fixedly mounted on the upper end of the movable frame 7, a guide slide rod 8 is fixedly connected to the middle end of the front surface of the housing 1, and the surface of the movable frame 7 is slidably connected to the surface of the guide slide rod 8.

[0028] In this technical solution, the slider 15, the movable frame 7, and the cleaning scraper 5 are arranged so that the slider 15 can be moved during the rotation of the reciprocating screw 14. The movement of the slider 15 can drive the movable frame 7 and the cleaning scraper 5 to move, so that the cleaning scraper 5 can further clean the surface of the transparent glass plate 6 under the action of movement, effectively improving the cleaning effect of the surface of the transparent glass plate 6. The guide rod 8 is arranged to support and guide the movable frame 7, so as to prevent the movable frame 7 from rotating or tilting during the movement.

[0029] Example 3:

[0030] Based on Embodiment 1, this utility model is as follows: Figures 1-4 As shown, a support plate 16 is fixedly connected to the left end of the top of the outer surface of the water tank 9. The left end of the reciprocating screw 14 is movably connected to the upper end of the support plate 16 through a bearing. A filling pipe 10 is fixedly connected to the upper end of the back of the water tank 9. A protective cover is threadedly connected to the top of the filling pipe 10. An air inlet check valve 12 is fixedly installed in the middle of the top of the water tank 9. The surface of the piston 24 is slidably connected to the inner cavity of the conveying cylinder 19. A rubber ring 21 is fixedly connected to the middle of the piston 24. The surface of the rubber ring 21 is slidably connected to the inner cavity of the conveying cylinder 19. Heat dissipation holes 3 are provided on the upper ends of both sides of the outer surface of the shell 1. The shape of the heat dissipation holes 3 is rectangular. A support column 2 is fixedly connected to the middle of the bottom of the outer surface of the shell 1. An installation plate is fixedly connected to the bottom of the support column 2.

[0031] In this technical solution, the support plate 16 is used to support the left end of the reciprocating screw 14, preventing the reciprocating screw 14 from tilting due to force. The filling pipe 10 facilitates the replenishment of water to the water tank 9. The air inlet check valve 12 allows outside air to enter the water tank 9 during the water extraction process, preventing negative pressure from forming inside the water tank 9. The rubber ring 21 effectively improves the sealing between the piston 24 and the conveying cylinder 19. The heat dissipation hole 3 allows the heat generated by the smart camera 11 during operation to be dissipated to the outside. The support column 2 and the mounting plate support the bottom of the housing 1 and facilitate installation and fixation by personnel using bolts.

[0032] The working principle of this utility model is as follows: The entire device is installed on one side of the personnel entrance / exit gate, so that the lens of the smart camera 11 faces the personnel entering through the gate. This allows the smart camera 11 to capture and recognize images of the clothing worn by the personnel, effectively improving the safety management level of the construction site. (It should be noted that, as existing technology, the smart camera 11 can analyze the captured image data using AI and match it with standard clothing data to determine whether it meets the requirements, and can issue an early warning when personnel are not dressed according to regulations.) The housing 1 and the transparent glass plate 6 provide both storage and protection for the smart camera 11. When dust covers the transparent glass plate 6 and obstructs the lens of the smart camera 11, the drive motor 13 is activated. The mechanism drives the reciprocating screw 14 and the L-shaped rotating rod 17 to rotate. The rotation of the L-shaped rotating rod 17 passes through the through slot on the movable frame plate 18, causing the movable frame plate 18, the upright rod 20, and the piston 24 to reciprocate vertically. The movement of the piston 24 allows water to be drawn from the water tank 9 through the conveying cylinder 19 and the first one-way valve 22, and then transported to the cleaning nozzle 4 through the second one-way valve 23. At the same time, the water is sprayed onto the surface of the transparent glass plate 6 through the cleaning nozzle 4, causing the dust attached to the surface of the transparent glass plate 6 to fall off under the action of the water. This achieves the purpose of automatically cleaning the dust covering the lens of the smart camera 11, effectively preventing dust from affecting the clarity of the monitoring and recognition image, and ensuring that the monitoring and recognition operation can be carried out stably.

[0033] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
