Abstract
Description
Technical Field
[0001] This utility model relates to the field of pump room technology, specifically an automatic control device for coal mine pump rooms. Background Technology
[0002] A coal mine pumping station, also known as an underground pumping station, refers to an underground chamber equipped with drainage equipment to remove underground water inflow. The number of pumping stations depends on the amount of underground water inflow and the drainage height. It is possible to set up only one at the lowest mining level, or to set up one every few stages to relay the water inflow of the entire mine. Both of these methods must be determined after technical and economic analysis. In mines developed using adits, underground water inflow can flow directly out of the adits, and there is no need to set up pumping stations.
[0003] Existing coal mine pumping stations are equipped with automatic water pipe opening and closing devices for ease of operation. However, since these automatic control devices are external components, they cannot be promptly repaired when problems occur. The water pipes must be stopped before replacement or repair can be performed, thus affecting the operation of the pumping station's pipelines and reducing the applicability of the automatic control devices. Therefore, we propose an automatic control device for coal mine pumping stations. Utility Model Content
[0004] The purpose of this utility model is to provide an automatic control device for coal mine water pump rooms, so as to solve the problem mentioned in the background art that when the automatic control device malfunctions, remedial measures cannot be taken in time, and the water pipes need to be stopped before replacement and maintenance can be carried out.
[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic control device for a coal mine water pump room, comprising a mounting plate, a control box, and a mounting box. The control box is located inside the mounting plate, and the mounting box is fixedly connected to the top of the control box. A sealing groove is formed inside the control box. A connecting pipe is fixedly connected to the inside of the control box via a flange. An electromagnetic main valve is fixedly connected to the ends of the connecting pipe via a flange. A sealing plate is provided inside the mounting box. A sealing valve plate is provided below the sealing plate in the mounting box. A connecting rod is fixedly connected to the top of the sealing valve plate. The sealing valve plate extends into the inner cavity of the sealing groove. A connecting column is fixedly connected to the inside of the mounting box. Limit grooves are formed on both sides of the inside of the connecting column. A plug rod is inserted into the inside of the connecting column.
[0006] Preferably, a water pipe is fixedly connected inside the mounting plate, and the water pipe is fixedly connected to the outside of the control box via a flange.
[0007] Preferably, a flow sensor is installed inside the connecting pipe on the left, and a pressure sensor is installed inside the connecting pipe on the right.
[0008] Preferably, a transition pipe is fixedly connected between the bottoms of the two control boxes via a flange, and an electromagnetic auxiliary valve is fixedly connected to the middle section of the transition pipe via a flange.
[0009] Preferably, the connecting rod has an insertion hole on its lower inner side, one end of the connecting rod is inserted into the insertion hole, the top end of the connecting rod passes through the mounting box and extends to the top of the mounting box, and a pressure spring is sleeved on the upper outer side of the connecting rod, and a fixing block is fixedly connected to the top end of the connecting rod.
[0010] Preferably, the bottom end of the pressure spring is fixedly connected to the top of the mounting box, and the top end of the pressure spring is fixedly connected to the fixing block.
[0011] Preferably, a limiting block is fixedly connected to the outer side of the insertion rod, the limiting block is located inside the limiting groove, an electromagnetic adsorption plate is fixedly connected to the other end of the insertion rod, and a protective shell is fixedly connected to the top of the mounting box and to the outside of the connecting rod.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: The automatic control device for coal mine water pumping stations has a control box installed on the two side cylinder connecting pipes of the electromagnetic main valve, and the control box is connected to the water pipe. An installation box is provided on the control box, and the sealing valve plate of the installation box extends into the sealing groove inside the control box. The sealing valve plate is connected by a connecting rod, which applies tension to a pressure spring. The connecting rod is positioned by inserting a plug rod into a socket hole. The plug rod is controlled to move and extend by an electromagnetic adsorption plate. When the two electromagnetic adsorption plates are adsorbed together, the plug rod unlocks from the socket hole. Under the action of the pressure spring, the sealing valve plate moves downward, sealing the control box and the electromagnetic main valve. When the electromagnetic auxiliary valve is activated and the transition pipe is opened, water flows through the water pipe. This allows for timely remediation, replacement, or repair of the control device after a problem occurs without affecting the normal operation of the water pumping station, thus improving its applicability.
