[0020] Furthermore, the driving structure includes a first motor 200 and a second motor 201, the first motor 200 and the second motor 201 are both mounted on the hydraulic oil tank 100, an oil pump 202 is mounted on the first motor 200 and the second motor 201, the two oil pumps 202 are both located in the hydraulic oil tank 100, the output ends of the first motor 200 and the second motor 201 are respectively connected to the driving shafts of the two oil pumps 202, the oil extraction ends of the two oil pumps 202 are both connected to the oil extraction pipes 203, the two oil extraction pipes 203 are both connected to the oil extraction filters 204, and the two oil pumps 20 2 are connected to the oil outlet ends of the two tubular check valves 205, the two tubular check valves 205 are connected to the same connecting pipe 206, the connecting pipe 206 is connected to one end of a delivery pipe 207, the other end of the delivery pipe 207 is connected to a three-way pipe 208, the three-way pipe 208 is connected to one end of an oil delivery pipe 209, the other end of the oil delivery pipe 209 is connected to a first oil circuit block 210, the first oil circuit block 210 is connected to a plurality of oil delivery pipes 211, the first oil circuit block 210 is connected to a plurality of manual reversing valves 212, the three-way pipe 208 is connected to the second oil circuit block 2 13, the second oil circuit block 213 is connected to the top side of the hydraulic oil tank 100, one end of a plurality of connecting pipes 214 is connected to the second oil circuit block 213, the other end of the connecting pipe 214 is connected to the first oil circuit block 210, the connecting pipe 214 is connected to a shunt pipe 215, and a plurality of oil circuit solenoid valves 216 are connected to the second oil circuit block 213. When the manual reversing valve 212 is in the closed state, the first motor 200 is driven to extract the hydraulic oil in the hydraulic oil tank 100 through the oil extraction pipe 203 and the oil extraction filter 204, and then the hydraulic oil is output through the tubular check valve 205. It is sent to the connecting pipe 206, and then transported to the delivery pipe 207 through the connecting pipe 206, and then enters the second oil circuit block 213 through the three-way pipe 208. The flow direction of the oil can be controlled by controlling the oil circuit solenoid valve 216, so that the oil can be transported through different connecting pipes 214 and then flow out through the diverter pipe 215. When the oil circuit solenoid valve 216 is closed, the hydraulic oil flows through the oil delivery pipe 209 to the first oil circuit block 210, and the flow direction of the oil is controlled by manually adjusting the manual reversing valve 212, so that it is delivered to the hydraulic equipment through different oil delivery pipes 211.

If the accumulator 301 leaks oil during long-term storage, the pressure sensor will sense it and automatically start the motor to inject hydraulic oil into the accumulator 301. When both the first motor 200 and the second motor 201 fail or the oil circuit leaks, the accumulator solenoid valve 304 on the accumulator 301 can be opened, so that the stored liquid starts to flow out, the pressure drops, and the oil supply to the hydraulic station is supplemented.

By controlling the manual reversing valve 212, the hydraulic oil can flow through the return oil pipe 400 to the return oil filter 401, and return to the hydraulic oil tank 100 after being filtered by the return oil filter 401, thereby achieving filtering and cleaning of the hydraulic oil.

[0023] The working principle is as follows: when in use, the oil delivery pipe 211 and the diversion pipe 215 can be connected to the hydraulic drive equipment of the mine waterproof and fireproof door respectively. When the manual reversing valve 212 is in the closed state, the first motor 200 is driven to extract the hydraulic oil in the hydraulic oil tank 100 through the oil extraction pipe 203 and the oil extraction filter 204, and then the hydraulic oil is transported to the connecting pipe 206 through the tubular one-way valve 205.

When the oil circuit solenoid valve 216 is closed, the hydraulic oil flows to the first oil circuit block 210 through the oil delivery pipe 209, and then the oil flow direction is controlled by manually adjusting the manual reversing valve 212, so that it is transported to the hydraulic equipment through different oil delivery pipes 211, providing power for the opening and sliding of the gates, ditch doors and movable slide rails in the mine, and multiple The mechanical structure operates in a certain logical sequence, and the oil circuit pressure sensor 302 can detect the oil pressure of the hydraulic station. When the first motor 200 fails or the pressure is insufficient, it can be switched to the second motor 201 for continued use. During use, the accumulator 301 can be connected to the oil circuit of the equipment through a pipeline. The first motor 200 or the second motor 201 can be used to flush hydraulic oil into the accumulator 301, and liquid or gas can be pressed into the accumulator 301. The pressure sensor in the accumulator 301 will monitor the increase in pressure and ensure that the pressure does not exceed the set pressure. When the liquid or gas in the container reaches the set pressure, the accumulator solenoid valve 304 automatically closes to store energy. If the accumulator 301 leaks oil during long-term storage, the pressure sensor will sense it and automatically start the motor to flush hydraulic oil into the accumulator 301. When both the first motor 200 and the second motor 201 fail or the oil circuit leaks, the accumulator solenoid valve 304 on the accumulator 301 can be opened to make the stored liquid start to flow out, the pressure drops, and the oil is replenished to the hydraulic station to keep its pressure constant.
