[0027] In this implementation scheme: The existing device {publication (announcement) number}: CN220646030U discloses a drainage pipeline for preventing and controlling water in coal mines. To solve the technical problems existing in this prior art, as disclosed in the background art above, "when the above design is in use, although the smaller coal and impurities in the water are collected at the bottom of the drainage seat, so that the coal and impurities can be uniformly processed at the drainage seat, and it is more convenient to clean the coal and impurities in the pipeline, but when cleaning the impurities inside the drainage seat, the drainage operation needs to be stopped to clean out the impurities. This process reduces the work efficiency." In combination with the use, this problem is obviously a real and relatively difficult problem to solve. In view of this, to solve this technical problem, a filter cleaning assembly 3 is added to this application document.

[0028] Furthermore:

[0031] The partition 305 divides the interior of the connection cover 301 into chamber 1 and chamber 2, and filter screens 306 are provided in both chamber 1 and chamber 2. Two sets of bottom plates 307 are provided, and the two sets of bottom plates 307 are used to block chamber 1 and chamber 2 respectively.

[0032] A first connecting pipe 302 is connected and fixed between the first pipeline 1 and the connecting cover 301. One end of the first connecting pipe 302 passes through the outside of the connecting cover 301 and extends into the second chamber of the connecting cover 301. A control valve 1 303 is fixedly installed inside the first connecting pipe 302 near one end of the first pipeline 1. A control valve 2 304 is fixedly installed inside the first pipeline 1 near one end of the connecting cover 301.

[0033] A third connecting pipe 311 and a second connecting pipe 310 are fixedly installed between the connecting cover 301 and the second pipe 2 respectively;

[0034] One end of the second connecting pipe 310 and the third connecting pipe 311 are both connected to the second pipeline 2, and the other ends of the second connecting pipe 310 and the third connecting pipe 311 pass through the connecting cover 301 and extend to chamber one and chamber two of the connecting cover 301 respectively. A control valve three 312 is fixedly installed in the interior of the second connecting pipe 310 near one end of the second pipeline 2, and a control valve four 313 is fixedly installed in the interior of the third connecting pipe 311 near one end of the second pipeline 2. The first connecting pipe 302 is connected to the first pipeline 1.

[0035] In this embodiment: when the drainage pipe for preventing and controlling water in a coal mine is used, the control valve 1 303 is first rotated to block the first connecting pipe 302, and the control valve 2 304 is opened at the same time, so that water directly enters the chamber 1 of the connecting cover 301 through the first pipe 1, and then the control valve 312 is opened to release the blockage of the second connecting pipe 310 entering the second pipe 2, and then the control valve 4 313 is rotated to block the third connecting pipe 311;

[0036] Then the water is transported to the connection cover 301 through the first pipe 1, and the drainage is filtered by the filter screen 306 inside the chamber 1. The filtered water enters the second connection pipe 310 and is discharged to the inside of the second pipe 2 for transportation;

[0037] When it is necessary to clean the impurities in Chamber 1, then rotate Control Valve 1 303 to release the blockage of the first connecting pipe 302. At the same time, rotate Control Valve 4 313 to release the blockage of the third connecting pipe 311. Then rotate Control Valve 2 304 so that the first pipe 1 enters the connecting cover 301 for blockage. At the same time, rotate Control Valve 3 312 to block the second connecting pipe 310. At this time, water enters the first connecting pipe 302 through the first pipe 1, is discharged into Chamber 2 of the connecting cover 301, and passes through the third connecting pipe 311 and is conveyed into the second pipe 2. At this time, the bottom plate 307 of Chamber 1 can be opened to clean the impurities in Chamber 1 of the connecting cover 301. Through this operation, when cleaning the impurities inside the connecting cover 301, the drainage operation does not need to be stopped, and the cleaning can be carried out, improving the drainage efficiency of the pipeline and the use effect of the device, meeting the actual use requirements;

[0038] When cleaning the filter screen 306 inside Chamber 1, Control Valve 3 312 can be opened. At this time, a part of the water conveyed into the second pipe 2 can enter the second connecting pipe 310 and be discharged into the connecting cover 301, so as to wash the impurities attached to the filter screen 306, thereby improving the cleaning effect and meeting the actual use requirements.

[0039] Furthermore;

At the same time, through the setting of the second sealing gasket 309, the sealing performance between the bottom plate 307 and the partition plate 305 can be increased, so as to effectively avoid water leakage from the gap between the bottom plate 307 and the partition plate 305 when cleaning the impurities in a group of chambers.

[0045] Working principle and usage process of the present utility model: For the drainage pipeline used in coal mine water control and prevention, during use, first rotate control valve 1 (303) to block the first connecting pipe (302). At the same time, open control valve 2 (304), and water directly enters chamber 1 of the connecting cover (301) through the first pipeline (1). Subsequently, open control valve 3 (312) to release the blockage of the second connecting pipe (310) from entering the second pipeline (2). Then rotate control valve 4 (313) to block the third connecting pipe (311). Subsequently, water is transported through the first pipeline (1) to the connecting cover (301) and filtered by the filter screen (306) inside chamber 1. The filtered water enters the second connecting pipe (310) and is discharged into the second pipeline (2) for transportation. When it is necessary to clean the impurities in chamber 1, then rotate control valve 1 (303) to release the blockage of the first connecting pipe (302). At the same time, rotate control valve 4 (313) to release the blockage of the third connecting pipe (311). Then rotate control valve 2 (304) to make the first pipeline (1) enter the connecting cover (301) for blockage. At the same time, rotate control valve 3 (312) to block the second connecting pipe (310). At this time, water enters the first connecting pipe (302) through the first pipeline (1), is discharged into chamber 2 of the connecting cover (301), and is transported to the second pipeline (2) through the third connecting pipe (311). At this time, the bottom plate (307) at the bottom of chamber 1 can be opened to clean the impurities in chamber 1 of the connecting cover (301). Through this operation, when cleaning the impurities inside the connecting cover (301), the drainage operation does not need to be stopped for cleaning, which improves the drainage efficiency of the pipeline and the usage effect of the device, meeting the actual usage requirements. When cleaning the filter screen (306) inside chamber 1, control valve 3 (312) can be opened. At this time, a part of the water transported to the second pipeline (2) can enter the second connecting pipe (310) and be discharged into the connecting cover (301), so as to flush the impurities attached to the filter screen (306), thereby improving the cleaning effect and meeting the actual usage requirements.
