Description

Technical Field

[0001] This utility model relates to the field of electromechanical equipment technology, specifically to an electromechanical device for underground drainage in coal mines. Background Technology

[0002] Coal mine drainage refers to the process of draining mine water that flows out of the mine during coal mining to ensure safe production and the safety of workers. The task of mine drainage is to discharge the mine water flowing out of the mine to the surface through the drainage system to prevent water-related accidents. If the mine water cannot be drained in time, it may cause the mine to be flooded, seriously affecting production and even causing casualties. Therefore, the mine drainage system is one of the important facilities to ensure safe production in the mine.

[0003] Given the importance of underground drainage work in coal mines, corresponding water and electrical equipment is required. The most common water and electrical equipment is the water pump, which is responsible for pumping out the water accumulated underground. However, the underground work area is sometimes large, so the length of a single pipeline is often insufficient, which affects the drainage effect. Utility Model Content

[0004] The purpose of this utility model is to provide an electromechanical device for drainage in coal mines, in order to solve the problem mentioned in the background art that the water pump is responsible for pumping out the water in the mine. However, the working area in the mine is sometimes large, so the length of the single pipe is often insufficient, which affects the drainage effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electromechanical device for underground drainage in coal mines, comprising a support plate, a pump body, and a motor. An end cover is fixedly installed on the left side of the pump body. An outlet is connected to the top of the pump body, and an inlet is connected to the bottom of the pump body. A pumping pipe is connected to the tail end of the inlet. A connector is fixed to the side of the pumping pipe, and a mating flange is fixed to the side of the connector. Mounting holes are provided on both the upper and lower inner sides of the mating flange, and locking pins are inserted into the mounting holes. Locking nuts are connected to both ends of the locking pins. A sealing ring is fixed between the two mating flanges. The side of one mating flange is connected to the pumping pipe, and the side of the other mating flange is connected to a connecting pipe. Branch pipes are connected to the front and rear ends of the pumping pipe. An internal threaded groove is fixed to the inner wall of the branch pipe near the port. A connecting post is connected to the internal threaded groove, and a sealing plate is fixed to the end face of the connecting post.

[0006] As a further technical solution of this utility model, a top flange is installed on the top of the water outlet, and pre-reserved holes are distributed in a ring in the top flange.

[0007] As a further technical solution of this utility model, the inner threaded groove and the connecting post form a threaded connection, and the lateral dimension of the sealing plate is larger than the internal dimension of the branch pipe.

[0008] As a further technical solution of this utility model, the branch pipes are evenly distributed in three groups at both ends of the pumping pipe, and the pumping pipe and the branch pipes are interconnected.

[0009] As a further technical solution of this utility model, the sealing ring is annularly designed, and the mounting holes are evenly distributed in annularly within the mating flange.

[0010] As a further technical solution of this utility model, the outer sides of the locking pin are fixed with external threads, and the external threads are threaded with locking nuts.

[0011] As a further technical solution of this utility model, two support frames are fixed to the top of the support plate, and a reinforcing plate is fixed to the side of one support frame. One right-angled side of the reinforcing plate is fixed to the support frame, and the other right-angled side of the reinforcing plate is fixed to the top of the support plate.

[0012] As a further technical solution of this utility model, the support plate has second connecting holes on both sides for connection, and the front end of the support frame has a groove, the top surface of the groove is connected to the first connecting hole.

[0013] Compared with the prior art, the beneficial effects of this utility model are: this kind of electromechanical equipment for underground drainage in coal mines not only improves the pipeline connection capability, but also improves the drainage extraction capability and support capability of the electromechanical equipment.

[0014] (1) By fixing the top flange at the top of the outlet and the reserved holes are evenly distributed in a ring inside the support frame, the position of the top flange can be connected to the pipeline later. At the same time, after the inlet is connected to the pumping pipe, the pumping pipe can pump water normally, or a connecting pipe can be added so that the connecting flange on the side of the connecting pipe is flush with the connecting flange on the side of the pumping pipe. After they are flush, the positions of the two mounting holes correspond one by one. Then, after inserting the clip, the locking nut is used to lock the assembly. Therefore, the pipeline connection capability is improved during the operation.

[0015] (2) By distributing the branch pipes in front of and behind the pumping pipe and connecting them to each other, auxiliary pipes can be connected to the branch pipes according to the drainage needs. When connecting, the internal thread groove is used to make threaded connection. Therefore, the drainage capacity can be improved by arranging them on the side. When the branch pipes are not needed, the connecting column and the internal thread groove are locked by rotating the sealing plate. This improves the overall drainage capacity during operation.

[0016] (3) Two sets of support plates are arranged at the front and rear positions of the pump body for support. At the same time, a second connecting hole is opened on both sides of the support plate to facilitate subsequent position fixing. A support frame is fixed at the top of the support plate, and a reinforcing plate is added to the side of the support frame to improve the support effect. A groove is opened on the front end face of the support frame. The opening of the groove facilitates connection and fixing with the pump body through the first connecting hole, thereby improving the overall support capacity. Attached Figure Description
