Description

Technical Field

[0001] This utility model relates to the field of mine drainage, specifically a mine drainage anti-clogging device. Background Technology

[0002] Mine drainage refers to the removal of groundwater and surface water that enters the mine during the construction and production process. It is one of the important means to overcome water hazards. In the absence of a thoroughly dredged water-bearing deposit, drainage must be relied upon to create a good working environment for mining operations and the health and safety of workers, so as to ensure the smooth progress of production.

[0003] In existing technologies, to prevent excessive water accumulation in mine shafts from flooding tunnels, causing floods, landslides, mudslides, and other geological disasters, mine shafts are generally drained. However, when draining mine shafts naturally, the presence of coal dust, silt, and other particulate matter in the mine can cause these substances to enter the drainage pipes with the water flow. Over time, the drainage pipes can become clogged with silt and other substances, affecting the water flow and thus the drainage efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention proposes a mine drainage anti-clogging device. This is because the presence of coal dust, silt, and other particulate matter in the mine during natural drainage can lead to blockages in the drainage pipes over time, affecting water flow and drainage efficiency.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a mine drainage anti-clogging device, including a water pump, the input end of the water pump is fixedly connected to a first drainage pipe, a second drainage pipe is provided on one side of the first drainage pipe, and a filter mechanism is provided on one side of the second drainage pipe.

[0006] The filtration mechanism includes a connecting pipe, the inner cavity of which is fixedly connected to the surface of a second drain pipe. An installation groove is formed on the surface of the connecting pipe, and the surface of the first drain pipe is fixedly connected to the inner cavity of the installation groove. An external sleeve is threaded onto the surface of the connecting pipe. A filter sleeve is installed within the inner cavity of the external sleeve. A support frame is fixedly connected to the bottom of the external sleeve, and a motor is fixedly connected to the inner cavity of the support frame. A support rod is installed within the inner cavity of the filter sleeve, with its bottom extending through to the bottom of the external sleeve. The bottom of the support rod is fixedly connected to the surface of the motor's output shaft, and a scraper is fixedly connected to the top of the support rod.

[0007] Preferably, the inner cavity of the outer sleeve is fixedly connected to a first sealing ring, and the surface of the support rod is provided with a second sealing ring, the bottom of which is fixedly connected to the inner cavity of the outer sleeve.

[0008] Preferably, the scraper has a hollow groove on its surface, and a brush is fixedly connected to the inner cavity of the hollow groove.

[0009] Preferably, a first hollow block is fixedly connected to the surface of the filter sleeve, and a second hollow block is fixedly connected to the inner cavity of the outer sleeve. Bolts are threadedly connected to the inner cavities of the first and second hollow blocks.

[0010] Preferably, a fixing block is rotatably connected to the surface of the support rod, a reinforcing rod is fixedly connected to the surface of the fixing block, and the bottom of the reinforcing rod is fixedly connected to the inner cavity of the outer sleeve.

[0011] Preferably, a connecting rod is fixedly connected to the surface of the external sleeve, and a ring is fixedly connected to one side of the connecting rod.

[0012] Preferably, the surface of the motor is provided with a protective shell, and the bottom of the protective shell is fixedly connected to the inner cavity of the support frame.

[0013] The advantages of this utility model are:

[0014] This invention solves the problem of mine water being drawn through the first and second drainage pipes by placing a second drainage pipe in water and starting a water pump. The water is then transported through the second drainage pipe to a connecting pipe. A filter sleeve inside the connecting pipe filters the water, causing impurities such as mud and sand to be deposited on the inner cavity and surface of the outer sleeve. The filtered water is then transported through an installation groove to the first drainage pipe. A motor is started to rotate a support rod, which in turn rotates a scraper. The scraper scrapes the inner wall of the filter sleeve, removing the impurities. The water is filtered through the filtration mechanism, leaving the mud and sand impurities inside the outer sleeve. After drainage is complete, the outer sleeve can be removed, and the mud and sand impurities deposited at the bottom of the outer sleeve can be poured out. This solves the problem of coal dust, mud, and other particulate matter in mines causing blockages in natural drainage systems, which hinder water flow and reduce drainage efficiency.

[0026] The filter mechanism 4 includes a connecting pipe 401, the inner cavity of which is fixedly connected to the surface of the second drain pipe 3. The surface of the connecting pipe 401 is provided with an installation groove 402. The surface of the first drain pipe 2 is fixedly connected to the inner cavity of the installation groove 402.

[0034] Working Principle: When using this device, workers drain water from mine shafts by placing the second drainage pipe 3 into the water. Then, pump 1 is started to draw water from the mine shaft through the first drainage pipe 2 and the second drainage pipe 3, achieving the drainage effect. Simultaneously, the water from the mine shaft is transported through the second drainage pipe 3 to the inner cavity of the connecting pipe 401. During this process, the filter sleeve 404 inside the connecting pipe 401 filters the water through its own filter holes, causing impurities such as mud and sand to be deposited into the inner cavity of the outer sleeve 403 and on the surface of the filter sleeve 404. The mounting groove 402 on the surface of the connecting pipe 401 connects to the opening of the first drainage pipe 2. The water filtered by the filter sleeve 404 is then transported through the mounting groove 402 to the first drainage pipe 2. During the drainage process, the motor 406 is started, and the output end of the motor 406 drives the support rod 407 to rotate. When the support rod 407 rotates, it drives the scraper 408 to rotate as well. The rotating scraper 408 scrapes the inner wall of the filter sleeve 404, removing the impurities attached to the inner wall of the filter sleeve 404 and preventing the impurities from clogging the filter holes of the filter sleeve 404 and blocking the water flow. At this time, the water is filtered through the filter mechanism 4, and the mud and other impurities in the water are filtered and left in the inner cavity of the outer sleeve 403. After the drainage is completed, the connecting pipe 401 is threadedly connected to the outer sleeve 403, and the outer sleeve 403 can be removed to pour out the mud and other impurities deposited at the bottom of the outer sleeve 403. This solves the problem that when natural drainage is carried out in mines, there are coal dust, mud and other particles in the mine. These substances will enter the drainage pipe with the water flow, and over time the drainage pipe is easily blocked by mud and other substances, which will hinder the water flow and affect the drainage efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
