In addition, the terms "first", "second", and "third" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance. The present invention is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-6 As shown, a fully automatic unattended monitoring device for a bucket wheel machine proposed by the present invention comprises a protective shell 1 and a monitoring camera 2, wherein the monitoring camera 2 is fixedly installed in the protective shell 1, and a cleaning mechanism 3 is provided in the protective shell 1 close to the front of the lens of the monitoring camera 2, and a plurality of electric heating tubes 4 are provided on the side of the protective shell 1 close to the front of the lens of the monitoring camera 2, so as to keep the temperature at the lens at a high state, thereby avoiding condensation of water vapor, avoiding the generation of frost and fog, and effectively ensuring the monitoring clarity of the monitoring camera 2; the cleaning mechanism 3 comprises a driving motor 5, a limiting rod 6, a threaded rod 7 and a movable cleaning plate 8, wherein the driving motor 5 is fixed on the inner wall of the protective shell 1, one end of the threaded rod 7 is rotatably arranged on the inner wall of the protective shell 1 away from the driving motor 5, and the other end of the threaded rod 7 is fixedly connected to the driving motor 5, and the bottom of the movable cleaning plate 8 is threadedly connected to the threaded rod 7, and the limiting rod 6 passes through the top of the movable cleaning plate 8 and is fixed on the inner wall of the protective shell 1, and an adjustable component 9 is provided on the movable cleaning plate 8.

[0025] like Figure 3-6 As shown, the adjustable component 9 includes a connecting box 10, a winding motor 11, an unwinding motor 12 and a cleaning cloth 13. The connecting box 10 is fixed on the outer wall of the movable cleaning plate 8 close to the monitoring camera 2. A vertically arranged protruding plate 16 is provided on the outer wall of the connecting box 10. The winding motor 11 and the unwinding motor 12 are symmetrically arranged under the bottom wall of the connecting box 10 on both sides of the protruding plate 16. A winding shaft 14 is fixedly connected to the winding motor 11, and an unwinding shaft 15 is fixedly connected to the unwinding motor 12. The top ends of the winding shaft 14 and the unwinding shaft 15 are rotatably arranged under the bottom wall of the connecting box 10, and both ends of the cleaning cloth 13 are wrapped around the protruding plate 16 and are tightened and wound around the winding shaft 14 and the unwinding shaft 15.

[0026] like Figure 3 , 4 As shown, the cross-section of the raised plate 16 is arc-shaped, which reduces friction and facilitates winding, while reducing the use area of ​​the cleaning cloth 13, so that the cleaning cloth 13 can be fully utilized. The cleaning cloth 13 at the raised plate 16 is close to the lens of the surveillance camera 2, and the cleaning cloth 13 wipes the lens clean.

[0027] like Figure 6 As shown, a plurality of pressure sensors 23 are provided vertically on one side of the unwinding shaft 15 away from the cleaning cloth 13. When the cleaning cloth 13 is unwound, the pressure sensor 23 cannot detect the pressure and transmits the signal to the terminal or mobile phone to replenish the new cleaning cloth 13. Both the unwinding shaft 15 and the winding shaft 14 are detachable for easy replacement.

[0028] like Figure 1 , 2As shown, a through hole 17 is provided on the side wall of the protective shell 1 close to the electric heating tube 4, and a support plate 18 is provided on the through hole 17. A rotating motor 19 is fixed on the support plate 18, and a fan blade 20 is provided on the rotating motor 19. The rotating motor 19 drives the fan blade 20 to rotate, blowing heat to the front of the monitoring camera 2, so that the heat is evenly distributed and the heating speed is accelerated.

[0029] like Figure 1 As shown, a space is left between the top wall of the surveillance camera 2 and the top wall of the protective shell 1, and a temperature sensor 21 and a control box 22 are provided under the top wall of the protective shell 1 near the front and rear of the surveillance camera 2 lens. The temperature sensor 21, the electric heating tube 4, the rotating motor 19, the driving motor 5, the winding motor 11 and the unwinding motor 12 are all electrically connected to the control box 22.

[0030] When in use, the monitoring camera 2 is installed on a monitoring bracket near the bucket wheel machine. The monitoring camera 2 can monitor the working status of the bucket wheel machine. When the lens of the monitoring camera 2 is contaminated with dust and needs to be cleaned, the driving motor 5 is started, the driving motor 5 drives the threaded rod 7 to rotate, the threaded rod 7 drives the movable cleaning plate 8 to move, and the movable cleaning plate 8 drives the cleaning cloth 13 to move, and the dust at the lens of the monitoring camera 2 is wiped clean. After one wiping is completed, the unwinding motor 12 and the winding motor 11 rotate in the same direction at the same time, and the winding shaft 14 brought by the winding motor 11 is opposite to the winding shaft 14. After wiping, the cleaning cloth 13 is rolled up, and the unwinding motor 12 drives the unwinding shaft 15 to unwind, and a new cleaning cloth 13 is placed on the raised plate 16, which is convenient for cleaning again, ensuring that a clean and effective cleaning cloth 13 can be used for each cleaning, which greatly improves the quality and effect of lens cleaning and extends the service life of the lens. When the cleaning cloth 13 is unrolled, the pressure sensor 23 cannot detect the pressure, and transmits the signal to the terminal or mobile phone, and the reel 14 and the unwinding shaft 15 and the used cleaning cloth 13 are removed, and a new cleaning cloth 13 is replaced;

[0031] When the temperature sensor 21 detects that the temperature drops, it controls the electric heating tube 4 to heat up, and the rotating motor 19 drives the fan blades 20 to rotate, blowing the heat to the front of the monitoring camera 2, so that the heat is evenly distributed, the heating speed is accelerated, and the lens is effectively prevented from frosting, ensuring normal imaging in a low temperature environment, so that it can run stably and smoothly under extremely cold conditions, and improving the reliability and efficiency of cleaning.

[0032] The present invention and its embodiments are described above, and such description is not restrictive. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if ordinary technicians in the field are inspired by it, without departing from the purpose of the invention, they can design a structure and embodiment similar to the technical solution without creativity, which should belong to the protection scope of the present invention.
