[0023] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

The side of the support block 2 is fixedly connected to a side plate 3. The side of the side plate 3 is fixedly connected to a front plate 4. An observation glass 5 is hinged inside the front plate 4. The top of the support block 2 is fixedly connected to a fixed block 6. The internal rotation of the fixed block 6 is connected to a screw 7. The top of the screw 7 is fixedly connected to a forward and reverse motor 8, and the external thread of the screw 7 is sleeved with a slider 9. The internal sliding connection of the slider 9 is a positioning rod 12. The bottom of the forward and reverse motor 8 is fixedly connected to the top of the fixed block 6. The top of the positioning rod 12 is fixedly connected to the bottom of the fixed block 6. The internal sliding connection of the side plate 3 is the fixed plate 1. 0, a cleaning block 11 is fixedly connected to the bottom of the fixed plate 10, and a fixing column 14 is fixedly connected to one side of the top of the fixed plate 10, the external thread of the screw 7 is adapted to the internal thread of the slider 9, and the screw 7 and the positioning rod 12 are parallel to each other, the cleaning block 11 is made of sponge material, and the front of the cleaning block 11 is in close contact with the back of the observation glass 5. When debris adheres to the back of the observation glass 5, turn on the forward and reverse motor 8, the screw 7 will rotate, the screw 7 will drive the slider 9 to move, and the slider 9 will drive the cleaning block 11 to move through the fixed plate 10, thereby cleaning the debris on the back of the observation glass 5 to avoid the problem of debris blocking the line of sight.

[0025] In addition, the other side of the top of the fixed plate 10 is fixedly connected to the limiting plate 13, the side of the fixed column 14 is slidably connected to the limiting rod 15, the outside of the limiting rod 15 is fixedly connected to a movable plate 17, and the side of the movable plate 17 is fixedly connected to a return spring 16, one end of the return spring 16 is fixedly connected to the side of the inner cavity of the fixed column 14, and the inside of the return spring 16 is slidably connected to the outside of the limiting rod 15, the movable plate 17 is located inside the fixed column 14, and the top and bottom of the movable plate 17 are both slidably connected to the top and bottom of the inner cavity of the fixed column 14, and a limiting groove 18 is opened inside the slider 9, and the limiting groove 18 is adapted to the limiting rod 15. When the cleaning block 11 needs to be replaced after being used for a long time, first pull the limit rod 15 to the left. The limit rod 15 will cause the return spring 16 to elastically deform through the movable plate 17, and the limit rod 15 will move, so that the limit rod 15 is separated from the limit groove 18 opened on the side of the slider 9. At this time, the fixed plate 10 can be pulled to separate the fixed plate 10 from the slider 9, thereby facilitating the disassembly and replacement of the cleaning block 11, which brings convenience to the use of the device.

[0026] Working principle: When debris adheres to the back of the observation glass 5, turn on the forward and reverse motor 8, the screw 7 will rotate, the screw 7 will drive the slider 9 to move, and the slider 9 will drive the cleaning block 11 to move through the fixed plate 10, thereby cleaning the debris on the back of the observation glass 5. After the cleaning block 11 has been used for a long time, when the cleaning block 11 needs to be replaced, first pull the limit rod 15 to the left, the limit rod 15 will cause the return spring 16 to elastically deform through the movable plate 17, and the limit rod 15 will move, so that the limit rod 15 is separated from the limit groove 18 opened on the side of the slider 9. At this time, the fixed plate 10 can be pulled to separate the fixed plate 10 and the slider 9, thereby facilitating the disassembly and replacement of the cleaning block 11, which brings convenience to the use of the device.
