This invention, by using a rubber scraper in conjunction with a nozzle that sprays cleaning agent onto the surface of the protective cover, effectively cleans mineral powder with strong adhesion to the protective cover surface compared to existing technologies that only use a scraper to clean the surface, thereby improving the cleaning effect on the protective cover.

[0004] The aforementioned camera has a cleaning effect, but existing cameras are prone to displacement due to collisions with debris in complex working environments, and are difficult to restore. Furthermore, the camera is difficult to install, and repeated disassembly and reassembly are required when adjusting the image. Therefore, there is a need to provide an intrinsically safe camera for mining. Utility Model Content

[0005] The purpose of this invention is to provide an intrinsically safe camera for mining, in order to solve the problems of existing cameras being misaligned due to collisions with debris and difficult to restore, as well as the complexity of image adjustment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intrinsically safe camera for mining, comprising a fixed plate, a camera, and a rubber pad, wherein a buffer mechanism is provided between the camera and the rubber pad; the buffer mechanism includes two slide rods, the two slide rods are respectively fixedly mounted on both sides of the camera, and buffer springs are fixedly mounted at both ends of the two slide rods, and a slide block is slidably mounted in the middle of the two slide rods, a fixed shaft is fixedly mounted through the slide block, three traction springs are fixedly mounted in the middle of the fixed shaft, and a connecting seat is sleeved on the outside of the fixed shaft, and a first fixed cap and a second fixed cap are respectively threaded onto the upper and lower ends of the fixed shaft.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1) This intrinsically safe camera for mining uses a fixed shaft, a first fixed cap, and a second fixed cap to connect and reinforce the slide and connecting seat in sequence, thereby realizing the installation of the buffer mechanism. The buffer spring can effectively provide lateral buffer for the camera, and the traction spring can effectively provide rotational buffer for the camera. Both can restore the position of the camera without external impact, solving the problem that existing cameras are easily displaced by collisions with foreign objects and are difficult to restore.

[0015] 2) This intrinsically safe camera for mining uses controls the sliding release of the first and second locking teeth to limit the first and second locking plates. Benefiting from the fact that the first locking plate is perpendicular to the second locking plate, the horizontal and vertical angles of the camera can be adjusted. After the camera angle is adjusted, the first and second locking teeth are released so that they can be inserted into the first and second locking plates under the action of the first and second support springs, respectively. This improves the debugging efficiency of the camera and eliminates the need to repeatedly disassemble and reassemble the camera. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1

[0023] Combination Figures 1-3A mining intrinsically safe camera includes a fixed plate 1, a camera 2, and a rubber pad 3. A buffer mechanism 4 is provided between the camera 2 and the rubber pad 3. The buffer mechanism 4 includes two slide rods 401, which are respectively fixedly installed on both sides of the camera 2. Buffer springs 402 are fixedly installed at both ends of the two slide rods 401. A slide block 403 is slidably installed in the middle of the two slide rods 401. A fixed shaft 404 is fixedly installed through the slide block 403. Three traction springs 405 are fixedly installed in the middle of the fixed shaft 404. A connecting seat 406 is sleeved on the outside of the fixed shaft 404. A first fixed cap 407 and a second fixed cap 408 are threaded onto the upper and lower ends of the fixed shaft 404, respectively.

[0024] All four buffer springs 402 are of the same length and are tightly attached to the slide block 403. The buffer springs 402 can effectively buffer the camera 2. Due to the connection between the buffer springs 402 and the slide block 403, the slide block 403 will always be located in the middle of the slide rod 401 when there is no external impact. The lower part of the slide block 403 has a strip groove, and the fixed shaft 404 is adapted to the strip groove to ensure that the slide block 403 and the fixed shaft 404 are relatively stationary. The upper part of the connecting seat 406 has three U-shaped grooves, and three traction springs 405 are adapted to the three U-shaped grooves respectively. In use, when the control connecting seat 406 is sleeved on the fixed shaft 404, the traction springs 405 are further matched and connected to the connecting seat 406. Due to the traction effect of the three traction springs 405, the slide block 403 rotates relative to the connecting seat 406 when the camera 2 is impacted. The traction springs 405 not only provide a buffering effect, but also pull the connecting seat 406 to reset. Bolt sets are provided on both outer sides of the connecting seat 406, and the rubber pad 3 and the connecting seat 406 are fixedly connected by two bolt sets. Example 2

[0025] See Figure 4 and Figure 5 A positioning mechanism 5 is provided between the fixing plate 1 and the rubber pad 3. The positioning mechanism 5 includes a first buckle plate 501, a first support rod 502 is rotatably installed in the middle of the first buckle plate 501, a first base 503 is fixedly installed in the middle of the first support rod 502, a first support spring 504 is fixedly installed on one side of the first base 503, a first buckle tooth 505 is fixedly installed at one end of the first support spring 504, a second buckle plate 506 is fixedly installed at one end of the first support rod 502, a second support rod 507 is rotatably installed in the middle of the second buckle plate 506, a second base 508 is fixedly installed in the middle of the second support rod 507, a second support spring 509 is fixedly installed on one side of the second base 508, and a second buckle tooth 510 is fixedly installed at one end of the second support spring 509.

[0026] The first buckle tooth 505 and the second buckle tooth 510 are respectively embedded and slidably mounted on the first support rod 502 and the second support rod 507. The first buckle tooth 505 and the second buckle tooth 510 are respectively adapted to the first buckle plate 501 and the second buckle plate 506. The first buckle plate 501 is perpendicular to the second buckle plate 506. The rubber pad 3 is fixedly connected to the second support rod 507, and the rubber pad 3 and the connecting seat 406 are fixedly connected by two bolt sets. In use, by controlling the first buckle tooth 505 to move forward along the first support rod 502, the buckle tooth 505 will be released. The restriction on the first buckle plate 501 can be quickly adjusted to change the elevation angle of the camera 2. By controlling the second buckle tooth 510 to move forward along the second support rod 507, the restriction on the second buckle plate 506 will be released, allowing the lateral angle of the camera 2 to be quickly adjusted. Once the angle of the camera 2 is adjusted, the first buckle tooth 505 and the second buckle tooth 510 can be released so that they can be embedded in the first buckle plate 501 and the second buckle plate 506 respectively under the action of the first support spring 504 and the second support spring 509, thus completing the positioning of the camera 2.

[0027] In actual operation, slide 403 and connecting seat 406 are sequentially controlled to be sleeved on fixed shaft 404, and traction spring 405 is fastened to connecting seat 406. First fixed cap 407 and second fixed cap 408 are used to fix them to both ends of fixed shaft 404, thus completing the installation of buffer mechanism 4. Among them, buffer spring 402 can effectively buffer camera 2. Benefiting from the connection between buffer spring 402 and slide 403, slide 403 will always be located in the middle of slide rod 401 when there is no external force collision. Benefiting from the traction of three traction springs 405, slide 403 rotates relative to connecting seat 406 when camera 2 is collided. Traction spring 405 not only provides buffering effect, but also pulls connecting seat 406 to reset.

[0028] When the first buckle tooth 505 moves forward along the first support rod 502, the restriction on the first buckle plate 501 is released, allowing the elevation angle of the camera 2 to be quickly adjusted. When the second buckle tooth 510 moves forward along the second support rod 507, the restriction on the second buckle plate 506 is released, allowing the lateral angle of the camera 2 to be quickly adjusted. Once the angle of the camera 2 is adjusted, the first buckle tooth 505 and the second buckle tooth 510 are released, allowing them to be embedded in the first buckle plate 501 and the second buckle plate 506 respectively under the action of the first support spring 504 and the second support spring 509, thus completing the positioning of the camera 2.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
