[0071] The working principle of Embodiment 1 of this application is as follows:

[0072] The driving motor 326 drives the scraper 31 to swing reciprocally, and the squeegee 42 on the mounting plate 41 is pressed against the outer surface of the window sash 21 through the pressing spring 44, so as to timely scrape the rain on the window sash 21; at the same time, when there is a lot of dust on the window sash 21, the cleaning agent is sprayed onto the window sash 21 through the nozzle 333, and then the driving motor 326 drives the scraper 31 to swing reciprocally, and the squeegee 42 on the mounting plate 41 is pressed against the outer surface of the window sash 21 through the pressing spring 44, and the dust on the window sash 21 is scraped off under the action of the cleaning agent, so as to reduce the influence of dust and rain on the outdoor camera for collecting environmental sanitation images.

[0073] Embodiment 2

[0074] Refer to Figure 2 and Figure 5 , the difference between this embodiment and Embodiment 1 is that, since the squeegee 42 is in frictional contact with the window sash 21 for a long time, it needs to be replaced every once in a while to ensure the scraping effect of the squeegee 42. To improve the replacement efficiency of the squeegee 42, the scraper 31 can be taken out from the rotating shaft 321. An installation groove 411 is provided at one end of the mounting plate 41 close to the window sash 21. The squeegee 42 includes an installation portion 421 and a scraping portion 422. The scraping portion 422 is fixedly installed on the installation portion 421. The installation portion 421 extends along both the length and width directions of the scraping portion 422. The installation portion 421 is snap-fitted into the installation groove 411, and the scraping portion 422 is located at one end of the installation portion 421 away from the bottom of the installation groove 411.

[0075] Refer to Figure 5, the installation part 421 is detachably arranged on the mounting plate 41 through the locking assembly 5. The locking assembly 5 includes a cover ring 51 and a locking bolt 52. The cover ring 51 passes through the scraping part 422 and abuts against the extended position of the installation part 421, and the cover ring 51 is located on the side of the installation part 421 away from the installation groove 411. The cover ring 51 locks the installation part 421 in the installation groove 411. The locking bolt 52 passes through the cover ring 51 and is threadedly installed on the mounting plate 41. There are multiple groups of locking bolts 52, and the multiple groups of locking bolts 52 are installed at intervals on the installation to detachably lock the cover ring 51 on the mounting plate 41.

[0076] The working principle of Embodiment 2 of this application is as follows:

[0077] When the scraping strip 42 needs to be replaced, take out the scraping plate 31, loosen the multiple groups of locking bolts 52 and take out the cover ring 51, replace the new rubber strip and snap it into the installation groove 411, then pass the cover ring 51 through the scraping part 422 and abut it against the installation part 421, lock the cover ring 51 on the mounting plate 41 through the locking bolt 52, and finally install the scraping plate 31 on the rotating shaft 321 to realize the replacement of the scraping strip 42.

[0078] Embodiment 3

[0079] Refer to Figure 6 and Figure 7 , the difference between this embodiment and Embodiment 1 is that in order to reduce the influence of rain, fog, dust, mosquitoes and the like entering the housing 2 on the camera, the inside of the housing 2 is kept sealed. However, since the working environment temperature of the camera is too high or too low, it will seriously affect the service life of the camera. Therefore, it is necessary to keep the temperature inside the housing 2 within a certain range; in this embodiment, a temperature control mechanism 6 for controlling the temperature inside the housing 2 is provided on the housing 2.

[0080] Refer to Figure 6 and Figure 7 , the temperature control mechanism 6 includes a cooling component 7, a heating component 8 and a thermostat. The cooling component 7 is arranged on the housing 2, and the cooling component 7 is used to cool the internal space of the housing 2. A cooling through hole 22 for cooling is fixedly opened on the housing 2, and both ends of the cooling through hole 22 communicate with the outside. The cooling component 7 includes a heat sink 71 and a fan 72. The heat sink 71 includes a partition plate 711 and multiple groups of fins 712. The multiple groups of fins 712 are installed at intervals on the partition plate 711. The multiple groups of fins 712 are used to increase the contact area and improve the heat conduction effect. The partition plate 711 is fixedly installed on the housing 2, and the partition plate 711 is hermetically connected to the housing 2. The multiple groups of fins 712 are all located inside the housing 2 to absorb the heat inside the housing 2; one end of the partition plate 711 away from the fins 712 is located in the cooling through hole 22, so that the heat sink 71 absorbs the heat inside the housing 2 and conducts it into the cooling through hole 22.

[0081] Reference Figure 6 and Figure 7 The fan 72 is fixedly installed on the housing 2. The fan 72 is located inside the cooling through hole 22. The fan 72 is used to accelerate the gas flow inside the cooling through hole. When it is necessary to cool the housing 2, the fan 72 is started to increase the gas flow rate inside the cooling through hole 22, and then the heat introduced into the cooling through hole 22 by the heat sink 71 is discharged from the cooling through hole 22 in time, finally realizing the cooling of the inside of the housing 2.

[0082] Reference Figure 6 and Figure 7 The heating component 8 is a plurality of heating plates 81 installed on the housing 2 at intervals. The plurality of heating plates 81 are used to heat the internal space of the housing 2 to raise the temperature of the internal space of the housing 2. At the same time, a placement frame 9 for placing a dryer is snap-fitted inside the housing 2. Since the outside temperature is much lower than the internal temperature of the housing 2, the water vapor inside the housing 2 is likely to condense on the inner side wall of the window sash 21, thereby reducing the shooting effect of the camera. By placing a desiccant in the placement frame 9, the water vapor content in the air inside the housing 2 is reduced, and then the probability of water vapor condensing on the window sash 21 is reduced, improving the shooting effect of the camera.

[0083] Reference Figure 6 and Figure 7 The thermostat is arranged on the housing 2. The thermostat is used to detect the temperature inside the housing 2. The thermostat is electrically connected to the fan 72 and the heating plate 81. The thermostat is used to control the start and stop of the fan 72 and the heating plate 81. When the thermostat detects that the temperature inside the housing 2 is higher than the maximum temperature value, the fan 72 is started to cool the inside of the housing 2. When the thermostat detects that the temperature inside the housing 2 is within the safe range value, the fan 72 and the heating plate 81 are turned off. When the thermostat detects that the temperature inside the housing 2 is lower than the minimum temperature value, the heating plate 81 is turned on to heat the inside of the housing 2. Through the combined action of the thermostat, the fan 72 and the heating plate 81, the temperature inside the housing 2 is controlled within the safe range value, thereby improving the service life of the camera.

[0084] The working principle of Embodiment 3 of this application is as follows:

[0085] The thermostat detects the temperature inside the housing 2 and selectively turns on the fan 72 or the heating plate 81 according to the detection result to reduce or increase the temperature inside the housing 2, so as to keep the housing 2 in a sealed state while keeping the temperature inside the housing 2 within a certain range, improving the service life of the camera inside the housing 2.

[0086] The above are all preferred embodiments of the present application, and do not limit the protection scope of the present application.
