[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0028] Embodiment 1:

[0029] Reference Figure 1-5 A dust removal device for a coal mine camera comprises a camera body 1, and also comprises: a bracket 201, which is rotatably connected to the camera body 1; a shell 202, which is fixedly connected to the bracket 201; a motor 203, which is fixedly connected to the shell 202, and the output end of the motor 203 passes through the shell 202; an electric push rod 204, which is fixedly connected to the output end of the motor 203, and the telescopic end of the electric push rod 204 faces the lens of the camera body 1; a rotating plate 4, which is fixedly connected to the telescopic end of the electric push rod 204; a plurality of groups of bristles 5, which are all fixedly connected to the rotating plate 4, and the bristles 5 are used to clean the lens of the camera body 1, a partition plate 205 is fixedly connected in the shell 202, a motor 102 is connected to the camera body 1, the output end of the motor 102 is fixedly connected to the bracket 201, a mounting seat 101 is fixedly connected to the camera body 1, and the motor 102 is fixedly connected to the mounting seat 101.

[0030] When the device is in use, Figure 1 As shown, it is located above the camera body 1 to reduce the entry of dust and avoid affecting the photography of the camera body 1. Since there is a lot of dust underground, if the subsequent accumulation of dust affects the photography ability of the camera body 1, the motor 102 can be started, and the bracket 201 can be rotated by the rotation of the motor 102, and then moved to Figure 2 In the position shown, the shell 202 is facing the lens, and then the electric push rod 204 is extended to move the rotating plate 4, thereby making the bristles 5 close to the lens, and then the motor 203 can be started to rotate the rotating plate 4. At this time, the bristles 5 rotate accordingly, and the dust accumulated on the lens is cleaned by the bristles 5, which is convenient for the use of the camera body 1.

[0031] After cleaning, reset to Figure 1 The location is convenient for next use.

[0032] Embodiment 2:

[0033] Reference Figure 1-5A dust removal device for a coal mine camera is basically the same as Example 1, and further: a groove is provided on the rotating plate 4, a spring member 401 is connected in the groove, a knocking block 402 is slidably connected in the groove, the knocking block 402 is connected to the spring member 401, and a plurality of groups of protrusions 206 are provided in the shell 202, and the protrusions 206 are used to contact the knocking block 402 to generate vibration.

[0034] Before cleaning, the rotating plate 4 can be moved by the electric push rod 204. Figure 4 As shown, the protrusion 206 is close to the inside. When the rotating plate 4 moves to the protrusion 206, it can stop moving and start the motor 203. The rotating plate 4 is rotated by the rotation of the motor 203. At this time, the rotation of the rotating plate 4 will make the knocking block 402 constantly contact with the protrusion 206. With the cooperation of the spring part 401, knocking vibrations will be continuously generated. These vibrations will be transmitted to the bristles 5, causing some dust that contacts the bristles 5 in daily environment to fall off, which is convenient for subsequent cleaning.

[0035] Embodiment 3:

[0036] Reference Figure 1-5 A dust removal device for a coal mine camera is basically the same as Example 1, and further: a water pipe 3 is connected to the bracket 201, the liquid outlet end of the water pipe 3 is connected to the shell 202, the water pipe 3 is used to discharge water to clean the bristles 5, and the water pipe 3 must be connected to the external water supply.

[0037] After the lens is cleaned, the housing 202 can be moved downward, with the opening of the housing 202 facing upward, water is discharged from the water pipe 3, and the electric push rod 204 moves the rotating plate 4 to the position of the protrusion 206, and then the rotating plate 4 can be rotated to enhance the cleaning effect through water and vibration to clean the bristles 5. After the cleaning is completed, the water injection can be stopped and the position can be restored to Figure 1 Place it in the middle and wait for it to dry naturally for next use.

[0038] You can also wash the lens with water before cleaning it, using the wet bristles 5 to clean the lens, but this will cause water droplets to remain on the lens surface, and there is a situation where the dried water droplets affect the camera effect.

[0039] The utility model can clean the lens of the camera body 1 through the rotatable bristles 5 when in use. At the same time, the bristles 5 can be self-cleaned through the arrangement of the knocking block 402 and the protrusion 206. The arrangement of the water pipe 3 can also increase the cleanliness of the bristles 5 to a certain extent, which is convenient for use in coal mines.

[0040] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent substitutions or changes within the technical scope disclosed by the present invention according to the technical solution and inventive concept of the present invention, which should be covered by the protection scope of the present invention.
