[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Example: Reference Figure 1-4The unmanned supermarket monitoring device shown in the figure includes a mounting plate 1, a protective cover 3, screws, a slider 4 and a camera 20. It should be noted that in this embodiment, the mounting plate 1, the slider 4 and the camera 20 can be installed in a manner that refers to the technical content adopted in an unmanned supermarket monitoring structure disclosed in a Chinese patent with a publication number of CN212776449U in the prior art, which will not be repeated here. An annular cavity is provided on the mounting plate 1, and an annular plate 2 is movably installed in the annular cavity. The protective cover 3 is installed on the side of the annular plate 2 by screws, and the side of the mounting plate 1 is provided with a A matching annular hole, a tooth groove 8 is provided on the inner wall of the circumference of the annular plate 2, a motor 5 is installed on the side of the mounting plate 1, and an active cavity connected to the annular cavity is provided on the mounting plate 1. A rotating rod 6 is rotatably installed on the relative inner wall of the active cavity. One end of the rotating rod 6 is installed on the output shaft of the motor 5. A gear 7 is sleeved on the rotating rod 6, and the gear 7 is meshed with the tooth groove 8. An L-shaped block 12 is provided on the right side of the mounting plate 1, and a semi-arc scraper 13 is detachably installed on the bottom inner wall of the L-shaped block 12. An elastic extrusion mechanism matched with the L-shaped block 12 is provided on the mounting plate 1, and the elastic extrusion mechanism is installed in cooperation with the slider 4.

[0023] By means of the above structure, when in use, the camera 20 is first monitored at different heights through the slider 4. When the camera 20 rises, the L-shaped block 12 will rise through the slider 4 and the elastic extrusion mechanism, and then the semi-arc scraper 13 will rise to avoid it, thereby avoiding obstruction to the camera 20 and affecting the monitoring effect. When the protective cover 3 needs to be cleaned, the semi-arc scraper 13 is first made to fit with the surface of the protective cover 3, and then the motor 5 is started. The output of the motor 5 will cause the rotating rod 6 to rotate. The rotation of the rotating rod 6 will cause the annular plate 2 to rotate through the gear 7 and the tooth groove 8. The rotation of the annular plate 2 will cause the protective cover 3 to rotate, and then different surfaces of the protective cover 3 will contact the semi-arc scraper 13, thereby cleaning the surface of the protective cover 3, and the semi-arc scraper 13 is always above the camera 20 to avoid obstruction during cleaning, which is convenient for use.

[0024] like Figure 2 As shown, the elastic extrusion mechanism includes a movable groove opened on the side of the mounting plate 1, a movable block 10 is movably arranged in the movable groove, an L-shaped block 12 is installed on the top of the movable block 10, a movable block 15 is installed on the side of the movable block 10, a through cavity adapted to the movable block 15 is opened on the mounting plate 1, a movable plate 16 is installed on the side of the movable block 15, a through hole adapted to the movable plate 16 is opened on the side of the mounting plate 1, an L-shaped extrusion plate 17 is installed on the side of the slider 4, and an elastic unit is arranged on the top of the movable block 10. The advantage of such an arrangement is that, through the arrangement of the movable block 10, the movable block 15, the movable plate 16 and the L-shaped extrusion plate 17, it is convenient for the semi-arc scraper 13 to avoid.

[0025] Specifically, when the camera 20 rises, the slider 4 rises, and the rising of the slider 4 will cause the L-shaped extrusion plate 17 to rise. The rising of the L-shaped extrusion plate 17 will squeeze the movable plate 16 to make it rise. The rising of the movable plate 16 will cause the moving block 10 to rise through the movable block 15. The rising of the moving block 10 will cause the L-shaped block 12 to rise, and then the semi-arc scraper 13 will rise to avoid it, thereby avoiding blocking the camera 20 and affecting the monitoring effect.

[0026] like Figure 2 As shown, the elastic unit includes a spring 11 installed on the top of the moving block 10, and the other end of the spring 11 is installed on the top inner wall of the moving groove. The advantage of this arrangement is that, through the arrangement of the spring 11, when the L-shaped extrusion plate 17 does not squeeze the movable plate 16, the moving block 10 is not subjected to force. The moving block 10 is not subjected to force and will be reset under the elastic action of the spring 11, thereby resetting the semi-arc scraper 13.

[0027] like Figure 2 As shown, a guide rod 9 is installed on the relative inner wall of the movable groove, and a guide hole is opened on the top of the movable block 10. The guide rod 9 passes through the guide hole. The advantage of this arrangement is that the guide rod 9 plays a certain guiding role, so that the movable block 10 moves in the horizontal direction.

[0028] like Figure 2 As shown, a pull rope is installed on the side of the moving block 10, and a limit ring 18 is installed on the other end of the pull rope, and a limit rod 19 is installed on the side of the mounting plate 1. The advantage of this arrangement is that through the arrangement of the limit ring 18 and the limit rod 19, it is convenient to limit the moving block 10 and prevent it from resetting, thereby facilitating avoiding the obstruction caused by the semi-arc scraper 13 when removing the protective cover 3.

[0029] like Figure 2 As shown, a buffer pad is arranged at the bottom of the moving block 10. The advantage of such arrangement is that the buffer pad can play a certain buffering role and reduce the vibration generated when the moving block 10 is reset.

[0030] like Figure 1 As shown, a mounting hole is provided at the top of the L-shaped block 12, in which a fixing bolt 14 is movably installed, and a threaded hole is provided at the top of the semi-arc scraper 13, in which the end of the fixing bolt 14 is threadedly installed. The advantage of this arrangement is that the semi-arc scraper 13 can be easily disassembled and replaced through the arrangement of the fixing bolt 14, thereby avoiding damage caused by long-term use and affecting the cleaning effect.

[0031] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
