[0035] The implementation principle of the embodiment of the present application is as follows: in the tape transport system at the waterproof gate of the underground metal mine, the water level sensor 12 installed in the load-bearing wall 1 will monitor the water depth in the load-bearing wall 1 in real time. When the water level exceeds the set threshold, a signal will be sent to the ground control terminal. At this time, the control terminal will send a signal to the cylinder controller 71 and the motor controller 114 to control the booster pump in the hydraulic cylinder 72 and the drive motor 111 in the drive mechanism 11. The motor controller 114 will first control the drive motor 111 to drive the drive wheel 112 to rotate, and drive the connecting frame a8 to move. The connecting frame a8 will drive the mobile conveyor 3 to move along the steel rail 10 through the connecting rod 9 at the bottom, so that the mobile conveyor 3 is misaligned with the incoming conveyor 2 and the outgoing conveyor 4. , the mobile conveyor 3 will move to one side of the incoming conveyor 2 to prevent affecting the closing of the door panel 6, and then the cylinder controller 71 will control the hydraulic cylinder 72 to push the slider 73 to move, the slider 73 will slide in the slide groove of the door panel 6, and push the door panel 6 to rotate around the connecting shaft 74, so as to isolate the incoming conveyor 2 from the outgoing conveyor 4, and realize the linkage closure of the mobile conveyor 3 and the door panel 6. When the water level sensor 12 detects that the water level is lowered, it will control the door panel 6 to open through the control terminal, and reset the mobile conveyor 3, connect the incoming conveyor 2 and the outgoing conveyor 4, and the ore can be transported normally at this time. When the incoming conveyor 2 is transporting ore, in order to clean the conveyor belt of the incoming conveyor 2 and prevent the ore from getting stuck, Into the conveyor belt, by setting a transmission mechanism 13 at the end of the connecting roller 139 of the incoming ore conveyor 2, the incoming ore conveyor 2 will drive the bevel gear a131 to mesh with the bevel gear b132 when it is running, thereby driving the bevel gear b132 and the transmission rod 133 to rotate, and when the transmission rod 133 rotates, it will drive the toggle rod 135 and the protrusion a136 to rotate, and the protrusion a136 will slide in the strip groove inside the connecting frame 137, thereby toggling the connecting frame 137 to move back and forth, and the moving rod 138 on one side of the connecting frame 137 will also move synchronously and drive the cleaning roller 14 to move back and forth. When the cleaning roller 14 moves, the inside will slide on the outside of the connecting rod 151, and the protrusion b152 at the end of the connecting rod 151 will slide in the spiral groove 1 inside the cleaning roller 14. 53, thereby guiding the cleaning roller 14 when it reciprocates and making it rotate reciprocally. Since the end of the cleaning roller 14 is movably connected to the moving rod 138 through a rotating shaft, it can rotate normally. The ball 154 on the outside of the connecting rod 151 can reduce the friction force of the cleaning roller 14 when it moves. When the cleaning roller 14 that moves and rotates synchronously contacts the conveyor belt in the incoming mine conveyor 2, it will increase the friction force with the conveyor belt, thereby cleaning its surface. When maintaining the water level sensor 12, by pushing the connecting block 16 to move, the connecting block 16 will move the push plate 20 on one side, so that the push plate 20 squeezes the spring 21 on one side. When the connecting block 16 moves, the block a22 and the block b23 at the bottom will also move.When the block b23 is disengaged from the card slot inside the connecting plate 17, the water level sensor 12 can be moved upward to drive the block a22 to disengage from the card slot inside the connecting plate 17. When the connecting block 16 moves upward, it will squeeze the rotating plate 18 to shrink the spring sheet 19 on its top. Then the water level sensor 12 can be pulled to drive the connecting block 16 to disengage from the inside of the connecting plate 17. After the maintenance is completed, the connecting block 16 on one side of the water level sensor 12 can be inserted into the connecting slot inside the connecting plate 17. When the wedge-shaped surface of the block a22 contacts the connecting plate 17, it will drive the connecting block 16 to move upward, squeeze the rotating plate 18, and the connecting block When 16 continues to move, it will squeeze the push plate 20 and the spring 21 on one side thereof. When the card block a22 contacts the limit groove, it will move down and fall into the limit groove. At this time, the water level sensor 12 can be released, and the spring 19 will also reset to push the rotating plate 18 to rotate, and the connecting block 16 will be limited once. The spring 21 will push the connecting block 16 through the push plate 20 to drive the card block b23 to engage with the card groove inside the connecting plate 17, completing the secondary limit of the connecting block 16, so that the position of the water level sensor 12 is fixed. In this way, the water level sensor 12 in the tape transportation system at the waterproof gate of the metal mine can be disassembled and maintained through the above operation.
