[0057] The implementation principle of the explosion-proof device of a mine-integrated base station in this application is as follows: An explosion-proof part 120 is arranged inside the explosion-proof housing 100. The explosion-proof part 120 divides the interior of the explosion-proof housing 100 into two cavities. One of the cavities is used to install circuit components. The explosion-proof housing 100 and the circuit components as a whole form a base station. A quick-connect joint 200 is installed on the side wall of the explosion-proof housing 100, and the quick-connect joint 200 is placed in the other cavity, so that the quick-connect joint 200 is separated from the circuit components, and at the same time the quick-connect joint 200 is electrically connected to the circuit components. Therefore, during use, there is no need to open the explosion-proof housing 100 for line connection. It only needs to connect the external line to the quick-connect joint 200, realizing the quick connection of the line. At the same time, the line can be quickly replaced, the operation process is convenient, and the safety of the operation process is enhanced.
