Description

Technical Field

[0001] The utility model relates to the technical field of intelligent water drainage devices, in particular to an intelligent water drainage device for coal mine aquifers. Background Technique

[0002] During coal mining, the water sources causing water disasters mainly come from two aspects. One is the water-rich aquiferous rock stratum enriched in the roof of the coal seam. During the coal seam tunneling process, a caving zone or disturbed fissures are generated, resulting in a water-conducting channel in the roof of the coal seam and causing waterlogging in the tunneling coal seam roadway. The other is the high-pressure aquiferous rock stratum in the floor of the coal seam. During the coal seam tunneling process, the overlying pressure of the aquiferous rock stratum decreases, resulting in the destruction of the original in-situ stress balance state and the generation of disturbed fissure water-conducting channels, thus causing waterlogging in the coal mine. Therefore, it is necessary to extract the water liquid in the aquifer.

[0003] In the prior art, a Chinese patent with the publication number of CN 220909763 U discloses a mine aquifer water drainage device, including a coal seam, an aquifer, and a borehole arranged between the coal seam and the aquifer.

[0019] In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "front", "upper", "lower", "left", "right", "vertical", "horizontal", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention.

[0020] The following combines the attached Figures 1-4 The present invention will be further described.

[0021] In order to solve the problems existing in the background technology, the present application proposes the following technical solution: an intelligent water drainage device for coal mine aquifers, including a water pump 1. The input end of the water pump 1 is fixedly connected to a first water pipe 2, and the output end of the water pump 1 is fixedly connected to a second water pipe 3. The bottom of the first water pipe 2 is fixedly connected to a fixed pipe 5. The water pump 1 is used to pump out the water liquid in the aquifer.

[0022] In a further design, a support frame 22 is fixedly connected to the outside of the fixed pipe 5, and a fixed cylinder 12 is fixedly connected to the outside of the support frame 22. An adjusting sleeve 9 is slidably connected in the fixed cylinder 12. The adjusting sleeve 9 is slidably sleeved on the outside of the fixed pipe 5. A floating component and a monitoring component are arranged in the adjusting sleeve 9. An adjusting component for controlling the lifting of the adjusting sleeve 9 is arranged outside the fixed pipe 5.

[0023] In a specific design, in order to facilitate water pumping, a plurality of through holes are arranged on the outside of the fixed cylinder 12. A rubber skin 18 is fixedly connected between the fixed cylinder 12 and the adjusting sleeve 9. Through the arrangement of the rubber skin 18, when the adjusting sleeve 9 is lifted and adjusted, the rubber skin 18 can be synchronously driven to expand or be received, realizing the communication between the adjusting sleeve 9 and the fixed cylinder 12, so that the water liquid can only enter the fixed cylinder 12 and the adjusting sleeve 9 through the through holes on the outside of the fixed cylinder 12.

[0024] Among them, the floating component in this embodiment includes a guide block 14 fixedly connected in the adjusting sleeve 9, a floating rod 16 slidably connected through the guide block 14, and a floating block 17 fixedly connected to the bottom of the floating rod 16. A measuring plate 15 is fixedly connected to the top of the floating rod 16.

[0025] Among them, the monitoring component includes a laser distance sensor 23 fixedly connected to the inner top of the adjusting sleeve 9 and a control box 4 fixedly connected to the outside of the water pump 1. A controller is provided in the control box 4. The laser distance sensor 23 and the water pump 1 are both electrically coupled to the controller. After the fixed pipe 5 is placed into the coal mine aquifer and the water liquid in the aquifer surges into the fixed cylinder 12, it will push the floating block 17 and the floating rod 16 upward. The laser distance sensor 23 measures the distance between it and the measuring plate 15. When the set distance is reached, the controller turns on the water pump 1, and the water pump 1 pumps water to extract the water liquid in the aquifer.

[0026] For the convenience of adjustment, the adjustment component provided in this embodiment includes a motor 7 and a threaded rod 8. A fixing plate 6 is fixedly connected to the outside of the fixed pipe 5, and a motor 7 and a guide rod 13 are fixedly connected to the outside of the fixing plate 6. The output end of the motor 7 is fixedly connected to the threaded rod 8. A connecting frame 10 and a connecting plate 11 are fixedly connected to the top of the adjusting sleeve 9. The guide rod 13 penetrates and is connected to the connecting plate 11, and the threaded rod 8 is threadedly connected to the connecting frame 10. By starting the motor 7 to drive the threaded rod 8 to rotate, the threaded rod 8 drives the adjusting sleeve 9 to perform lifting adjustment through the connecting frame 10.

[0027] To prevent impurities from clogging the water pump 1, a rotating rod 19 is rotatably connected in the fixed cylinder 12. An impeller 20 is fixedly connected to the outside of the rotating rod 19. The rotating rod 19 is located in the fixed pipe 5, and multiple groups of crushing knives 21 are fixedly connected to the outside of the rotating rod 19. When the liquid enters the fixed pipe 5, by hitting the impeller 20, it will also drive the impeller 20 and the rotating rod 19 to rotate. The rotating rod 19 drives the crushing knives 21 to rotate, and the crushing knives 21 can crush the impurities mixed in the water liquid to prevent clogging of the water pump 1.

[0028] The usage method of this embodiment is as follows:

[0029] Place the fixed pipe 5 into the coal mine aquifer. After the water liquid in the aquifer surges into the fixed cylinder 12, it will push the floating block 17 and the floating rod 16 upward. The laser distance sensor 23 measures the distance between it and the measuring plate 15. When the set distance is reached, the controller turns on the water pump 1, and the water pump 1 pumps water to extract the water liquid in the aquifer;

[0030] When the water liquid enters the fixed pipe 5, by hitting the impeller 20, it will also drive the impeller 20 and the rotating rod 19 to rotate. The rotating rod 19 drives the crushing knives 21 to rotate, and the crushing knives 21 can crush the impurities mixed in the water liquid to prevent clogging of the water pump 1;

[0031] When the water liquid in the aquifer decreases and the floating rod 16 drops, the measured distance by the laser distance sensor 23 increases. When the set distance is reached, the controller turns off the water pump 1 to realize the on-off of the intelligent water pump 1.

[0032] In addition, the motor 7 can be started to drive the threaded rod 8 to rotate, so that the adjusting sleeve 9 of the fixed cylinder 12 can be lifted and lowered outside the fixed cylinder 12, and the distance between the floating rod 16 and the fixed cylinder 12 can be adjusted. With such a setting, different water level monitoring heights can be set according to different aquifers.

[0033] In the description of the present invention, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0034] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, the scope of the present invention is defined by the appended claims and their equivalents.
