Description

Technical Field

[0001] The present invention belongs to the technical field of gas extraction, and in particular relates to a device and method for controlling the conduction state of an extraction pipe. Background Art

[0002] There are tens of thousands of gas extraction boreholes and extraction pipes in coal mines. Mechanical valves are installed on the extraction pipes to adjust the conduction status of the extraction pipes. Currently, manual adjustment is mainly relied on. Due to the large number of borehole extraction pipes, the labor intensity is high and the adjustment frequency is low. When leakage, blockage and other problems are detected in the borehole, the borehole cannot be closed remotely in time. At the same time, it is impossible to reasonably adjust the conduction status of each borehole extraction pipe in a timely manner according to the extraction situation of each borehole. There are problems such as unreasonable negative pressure distribution, which affects the extraction efficiency and effect.

[0003] If a group of electric or pneumatic valves are installed on the borehole extraction pipeline, the conduction state of the extraction pipe is controlled by remotely controlling the state switching of the electric or pneumatic valves. Although automation can be achieved, the electric valves require a large number of electronic control wiring; existing pneumatic valves also mostly use solenoid valves to control the action, which requires a large number of wiring and PLC or CPU control points. In coal mines, especially in gas extraction sites, there are strict controls on live equipment (for example, cables are not allowed to be laid above the extraction pipeline). Even for mining explosion-proof electrical equipment, due to the large number of drill holes, if a large number of them are installed and used, there will be a great risk of explosion failure and safety hazards. In addition, a large number of wiring and debugging make the system construction more complicated and the later maintenance inconvenient. In addition, mining explosion-proof electrical equipment is generally sold at a high price, and the system cost is high, making it difficult to promote and apply on a large scale.

[0004] In order to solve the above problems, there is an urgent need for a device and method for controlling the conduction status of extraction pipes to achieve remote automatic control of the conduction status of a large number of borehole extraction pipes, without the need for a large number of live equipment or wiring. The system is easy to install and maintain, low in cost, and suitable for popularization and application. Summary of the invention

11. A method for controlling the conduction state of a pumping pipe, characterized in that: The method is implemented using the extraction pipe conduction state control device according to claim 8 or 9, comprising the following steps: Step 1: Install each gas-controlled valve on each borehole extraction pipeline, and connect each pneumatic valve to the gas source through each gas line valve; Step 2: When the conduction state of a certain borehole extraction pipeline needs to be adjusted, the remotely controlled mobile control platform moves along the track to the gas circuit valve position corresponding to the gas control valve on the borehole extraction pipeline; Step 3: The remote control actuator performs an action, pushes the control rod of the gas circuit valve, switches the gas circuit valve to the conduction state of the first gas circuit valve outlet, and the high-pressure gas flows through the first gas circuit valve outlet to the first gas inlet of the gas control valve, driving the gas control valve to perform an action, thereby realizing the control of the conduction state of the drilling hole extraction pipeline; Step 4: At the same time, the actuator and the air circuit valve control rod are attracted by magnetic force. If the air control valve is to perform a reverse action, the actuator can be controlled to perform a reverse action, driving the air circuit valve control rod to switch the second air circuit valve outlet to a conducting state, and the high-pressure gas flows through the second air circuit valve outlet to the second air inlet of the air control valve, driving the air control valve to perform a reverse action; Step 5: After the control is completed, the mobile control platform is controlled to move along the track to the next position, the actuator is separated from the air circuit valve control rod, the air circuit valve is automatically reset, and the air control valve stops moving; Step 6: Repeat steps 2 to 5 to achieve remote control of the conduction status of each borehole extraction pipeline.
