[0021] In order to make the content of the utility model more easily and clearly understood, the utility model is further explained in detail below according to specific implementation examples and in combination with the drawings.

[0022] As Figures 1 to 5As shown, the embodiment provides a mine-used intrinsic safety camera with automatic cleaning function, which comprises a cover plate 1 and a box body 2, one end of the cover plate 1 is hinged to one side of the box body 2, the cover plate 1 and the box body 2 are fixedly connected through a quick opening structure 5, the quick opening effect of the cover plate 1 can be realized, the installation mode of screw fixed connection is avoided, and the cover plate 1 is very fast and convenient to open and close. The camera module 6 and the circuit board 7 are installed in the box body 2, the lens glass 3 and the wiper assembly 4 are arranged on the front side wall of the box body 2. The lens of the camera module 6 directly faces the lens glass 3 to monitor the video of the underground working site, and the circuit board 7 is powered, communicates, transmits and electrically controls. When dust and stains appear on the lens glass 3 to affect shooting, the lens glass 3 is cleaned by the wiper assembly 4.

[0023] As shown in Figure 1 , 2 , the quick opening structure 5 of the embodiment comprises a hasp lock 51 and a lock tongue 52, a pair of hasp locks 51 are arranged on the left and right side walls of the box body 2 respectively, and a pair of lock tongues 52 matched with the hasp locks 51 are arranged on the left and right side walls of the cover plate 1. The hasp lock 51 of the embodiment adopts a Haitan DK604-1-2 type hasp lock 51, and the lock tongue 52 is used in combination with the hasp lock 51. The key is inserted into the hasp lock 51 and rotated to unlock, and then the hasp is separated from the lock tongue 52 to unlock the cover plate 1.

[0024] As shown in Figure 3 , the front side wall of the box body 2 of the embodiment is provided with a fan-shaped groove 21, and the lens glass 3 is also fan-shaped and is glued in the fan-shaped groove 21.

[0025] As shown in Figure 3 , 5 , the wiper assembly 4 of the embodiment comprises a motor 41, a wiper base 42, a wiper handle 43, a first wiper strip 44 and a second wiper strip 45. The motor 41 is arranged in the box body 2, the wiper base 42 is arranged on the front side wall of the box body 2, and the motor 41 drives the wiper base 42 to rotate. The wiper handle 43 is connected with the wiper base 42, and the first wiper strip 44 is fixed on the wiper handle 43. As shown in Figure 4 , the first wiper strip 44 is provided with a mounting groove 441, and the second wiper strip 45 is inserted into the mounting groove 441.
