The driving block 18 drives the limiting component 22 to unlock the cleaning component 23, so that the scraper block 2304 is ejected, thereby cleaning the sponge plate 1506, which is beneficial to further improve the cleaning effect of the device.

[0039] See also Figure 2 In order to improve the degree of automation in the use of the device, the box body 4 in this embodiment includes a shell 401 fixed to the top of the rotating seat 3, and a filter plate 402 is slidably connected between the inner cavity walls on the left and right sides of the shell 401 and penetrates to the back thereof.

[0040] It can also be seen that, by sliding the movable column 409 on the connecting seat 408, it is helpful to limit the top support plate 407, so that it is helpful to lift the protective cover 5 through the top support plate 407 and flip it backwards, thereby realizing the opening of the top plate of the outer shell 401. Through the coordinated setting of the sensor 6, it is helpful to pop out the protective cover 5, which is beneficial to improve the degree of automation of the use of the device.

[0041] A Y-shaped sliding channel is provided on the opposite side of the two connecting seats 408, and the moving column 409 is slidably connected to the connecting seat 408 through the sliding channel. A top support plate 407 is fixed on the opposite side of the left and right moving columns 409, and a Z-shaped linkage rod 406 is fixed between the two top support plates 407.

[0042] The structural setting of the linkage rod 406 facilitates the stable flipping of the protective cover 5, which facilitates the stable use of the device. The setting of the sliding channel facilitates the rotation of the bottom movable column 409 around the top movable column 409, thereby realizing the cover opening function and facilitating the stable use of the device.

[0045] See also Figure 3In order to clean the display screen 24, the active component 15 in this embodiment includes a water tank 1501 fixed to the connecting block 17. The top of the water tank 1501 is open and the bottom is inclined. A fixed column 1502 movably connected to the bottom of the water storage tank 19 is fixed on the inner bottom wall of the water tank 1501.

[0046] The bottom setting of the water tank 1501 helps to increase the water pressure in the water tank 1501, which helps to quickly discharge the water, quickly wet the sponge board 1506, and improve the cleaning efficiency of the device.

[0047] A water passing hole is provided on the back of the water passing tank 1501, and a water outlet hole is provided at the bottom of the water storage tank 19.

A threaded column 1504 that penetrates into the inner side of the water passing tank 1501 is movably connected to the back of the water passing tank 1501.

[0048] It is not difficult to find that the plug-in setting and the fitting setting of the sealing disk 1503 are conducive to the stability of the water in the water storage tank 19, and the setting of the water outlet hole is conducive to the outflow of water, which is conducive to the stable use of the device.

[0049] The outer side of the threaded column 1504 is threadedly connected to a locking plate 1505 located on the inner side of the water tank 1501, and the bottom of the threaded column 1504 is fixed with a sponge board 1506 that fits the back of the water tank 1501, and the back of the sponge board 1506 is located in the same plane as the front of the display screen 24.

[0050] In this embodiment, the threaded column 1504 is locked by the locking disk 1505, which is conducive to fixing the sponge board 1506, and at the same time realizes the disassembly and replacement function of the sponge board 1506, which is conducive to further improving the stability of the device.

[0051] See also Figures 5 to 6 In order to improve the stability of the device, the limiting assembly 22 in this embodiment includes a fixed shell 2201 fixed to the front side of the shell 401, a movable shell 2202 is slidably connected to the inner side of the fixed shell 2201, a pressure block 2203 adapted to the driving block 18 is fixed on the side of the movable shell 2202 away from the fixed shell 2201, and a spring 2204 is fixed on the inner cavity wall of the movable shell 2202 close to the pressure block 2203.

[0052] In addition, the provision of the elastic spring 2204 is helpful for supporting the limiting rod 2206, thereby facilitating the limiting rod 2206 to limit the cleaning component 23, thereby facilitating the stable use of the device.

[0053] A connecting column 2205 is fixed on the inner cavity wall of the movable shell 2202 away from the pressing block 2203 , and a limiting rod 2206 penetrating to the outside of the fixed shell 2201 is slidably connected to the inner side of the connecting column 2205 . An inclined block is fixed on the side of the limiting rod 2206 away from the movable shell 2202 .

[0054] The setting of the inclined block facilitates the cooperation with the cleaning assembly 23, thereby realizing the displacement of the limiting rod 2206, thereby facilitating the flip block 2302 to be located on the back of the limiting rod 2206, thereby realizing the resetting of the cleaning assembly 23, which is conducive to the stable use of the device.

[0055] The limiting rod 2206 is fixed to the side of the elastic spring 2204 away from the movable shell 2202, and the action blocks 2207 are fixed on the inner cavity walls on the upper and lower sides of the movable shell 2202. The inner side of the limiting rod 2206 is movably connected with a connecting rod 2208 that runs through the upper and lower sides thereof. The upper and lower sides of the connecting rod 2208 are fixed with movable blocks 2209 that fit with the action blocks 2207. The upper and lower action blocks 2207 and the movable blocks 2209 are both flipped mirror images.

[0056] In this embodiment, the setting of the movable block 2209 and the action block 2207 facilitates the displacement of the limit rod 2206 through the interference of the action block 2207, thereby achieving control over the cleaning component 23, which is beneficial to the stable use of the device.

[0058] Moreover, the provision of the supporting spring 2303 is helpful in supporting the flip block 2302, thereby facilitating the flip block 2302 to be ejected, thereby enabling the sponge plate 1506 to be cleaned by the scraping block 2304, thereby improving the cleaning effect.

A placement opening is provided at the front of the shell 401, and the cleaning component 23 is located in the placement opening.

[0060] In this embodiment, the structural setting of the reset block 2306 is conducive to squeezing the inclined block, thereby realizing the movement of the limit rod 2206, thereby facilitating the reset of the flip block 2302, thereby facilitating the hiding of the scraper block 2304, and thereby facilitating the improvement of the stability of the device.

[0061] The electrical components appearing in the text are all electrically connected to the controller and the power supply. The control method of the present invention is controlled by the controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power supply is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0062] The working principle of the above embodiment is:

[0063] (1) The driving motor 7 supplies energy to drive the driving gear 8 to rotate. Through the meshing action, the rotation of the rotating column 10 is realized, thereby driving the rotating seat 3 to rotate, realizing the change of the orientation of the display screen 24, which is beneficial to the improvement of the use effect of the device. Through the setting of the sensor 6, the external weather environment is monitored. When it rains outside, the rotating motor 403 is started, thereby driving the rotating plate 404 to rotate, thereby realizing the stable rise of the top moving column 409 through the rotation action and the limited sliding action of the moving column 409 and the connecting seat 408. When the top moving column 409 moves to the top of the connecting seat 408, the hinged action of the hinged plate 405 is used to realize the rotation of the top support plate 407 around the top moving column 409, thereby driving the protective cover 5 to open, and the falling rainwater is filtered out through the filter plate 402. The filter is performed to collect rainwater. When the display screen 24 needs to be cleaned, the water pump 21 is started to guide the water in the housing 401 into the water storage tank 19 through the water pipe 20. After a certain amount of water is transmitted, the servo motor 11 is started to rotate the worm 12 to drive the threaded rod 14 to rotate, thereby driving the connecting block 17 to descend, thereby driving the fixed column 1502 to be drawn out of the water storage tank 19, thereby leaking the water in the water storage tank 19 into the water tank 1501, and the water flows into the sponge board 1506 through the water hole to wet the sponge board 1506. Subsequently, the sponge board 1506 is driven to continue to descend by the servo motor 11, thereby lifting and wiping the front of the display screen 24. The rainwater is automatically collected and the display screen 24 is cleaned by the wet sponge board 1506, thereby improving the cleaning effect.

[0064] (2) When the sponge plate 1506 needs to be cleaned, the connecting block 17 is further moved downward, and the driving block 18 and the pressing block 2203 are squeezed to drive the movable shell 2202 to move, and the connecting rod 2208 is moved by squeezing the action block 2207 and the movable block 2209, thereby driving the limit rod 2206 to move away from the front of the flip block 2302, and the flip block 2302 is ejected by the elastic force of the supporting spring 2303, so that the outer surface of the rising sponge plate 1506 is scraped by the scraping block 2304, thereby scraping off the impurities, and then the hook plate 16 contacts the front of the flip block 2302. After that, it is hooked up and the inclined block is squeezed by the reset block 2306, thereby driving the limit rod 2206 to retract, so that the limit rod 2206 contacts the front of the flip block 2302, thereby realizing the retraction of the cleaning component 23. When the scraper block 2304 needs to be cleaned, the flip block 2302 is slid to one side by squeezing the top support spring 2303, so that the plug column 2301 is disengaged from the flip block 2302, thereby realizing the removal of the flip block 2302. At the same time, the sponge plate 1506 can be cleaned by unlocking the thread of the locking disk 1505. By cleaning the cleaning tool, it is beneficial to improve the cleaning effect.
