Description

Technical Field

[0001] This utility model relates to the field of XXX technology, and in particular to a water control and drainage device for coal mine geological engineering. Background Technology

[0002] Coal mining disrupts the balance of the original strata, leading to frequent geological disasters in coal mines. Coal mine water hazards are one of the main hazards threatening safe production in coal mines, including roof water inrush, floor water inrush, water hazards in old workings, and karst water hazards. These water hazards can not only cause mine flooding but also result in casualties and property damage. By carrying out water prevention and drainage work, the frequency of water hazard accidents can be effectively reduced, ensuring the safety of coal mine production.

[0003] Chinese patent discloses a drainage device for water control in coal mine geological engineering (publication number CN218581654U). This patented technology collects seeping water through a water collection hopper. When the water is discharged, it enters the drain pipe through the water collection hopper. When the water enters the drain pipe, it drives the impeller to rotate, which in turn drives the rotating shaft to rotate. The rotating shaft drives the turntable and cleaning brush to rotate, and the cleaning brush cleans the coal mine residue and stones on the top surface of the filter screen to prevent clogging of the filter holes. However, because the height of the filter screen is lower than the height of the water collection hopper port, although the cleaning brush can clean the coal mine residue and stones on the top surface of the filter screen, as the amount of coal mine residue and stones on the top surface of the filter screen gradually increases, the cleaning brush has difficulty in discharging the coal mine residue and stones accumulated on the top surface of the filter screen to the outside of the water collection hopper port, resulting in poor anti-clogging effect.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-4 This utility model provides a technical solution for a water control and drainage device for coal mine geological engineering: it includes a water collection tank 1, a stainless steel filter screen 5 connected to the top of the water collection tank 1, a drain pipe 6 connected to the bottom of the water collection tank 1, wing plates 22 connected to both sides of the water collection tank 1, a pair of bearing seats 3 connected to the top of the wing plates 22, a reciprocating screw 4 rotatably connected inside the pair of bearing seats 3, a drive mechanism provided at the left end of the reciprocating screw 4, a ball nut pair 13 sleeved on the outside of the reciprocating screw 4, a fixing sleeve 15 fixedly connected to the outside of the ball nut pair 13, a side plate 12 connected to one side of the fixing sleeve 15, a shell 11 connected to both sides of the side plate 12, and a shovel plate 10 connected to the front of the shell 11.

[0024] Both sides of the wing plate 22 are connected to mounting bases 2. Anchor rods are added and inserted into the mounting bases 2, extending to the roof of the coal mine, to facilitate the fixing of the device.

[0025] like Figure 1and Figure 2 As shown, the drive mechanism includes a motor 14, the top of which is fixedly connected to the wing plate 22. One end of the output shaft of the motor 14 is connected to a first pulley 8. A belt 7 is sleeved on the outer side of the first pulley 8, and a second pulley 9 is connected to the inner side of the belt 7. The inner ring of the second pulley 9 is fixedly connected to the left end of the reciprocating screw 4. When the motor 14 is turned on, the first pulley 8 is rotated. Through the connection of the belt 7, the second pulley 9 and the reciprocating screw 4 are rotated, which in turn causes the outer ball nut pair 13 and the fixing sleeve 15 to slide left and right. This causes the shovel plates 10 on both sides of the side plate 12 to slide left and right, removing the coal mine residue and stones above the stainless steel filter screen 5 and discharging them through both sides of the water collection tank 1.

[0026] like Figure 1 and Figure 2 As shown, a third through hole 23 is provided on the left side of the wing plate 22, and the belt 7 passes through the interior of the third through hole 23.

[0027] like Figure 3 and Figure 4 As shown, ten positioning slots 19 are horizontally opened on the front side of the outer shell 11. A back plate 16 is connected through the inside of the positioning slots 19. The right side of the back plate 16 is fixedly connected to the shovel plate 10. A second through hole 21 is opened on the left side of the back plate 16. A positioning mechanism is set inside the second through hole 21. The bolts 17 and nuts 18 can be removed from the outer shell 11 and the back plate 16 to facilitate the removal of the shovel plate 10 for maintenance and replacement. Conversely, the bolts 17 can be inserted into the outer shell 11 and the back plate 16 to complete the fixed connection between the back plate 16 and the shovel plate 10.

[0028] like Figure 3 and Figure 4 As shown, the positioning mechanism includes a bolt 17, one end of which passes through the interior of the outer shell 11 and the back plate 16 and is threaded with a nut 18. By setting the bolt 17 and the nut 18, it is convenient to position the shovel plate 10.

[0029] like Figure 3 and Figure 4 As shown, the outer casing 11 has corresponding first through holes 20 on both sides. One end of the bolt 17 passes through the interior of a pair of first through holes 20. By rotating the nut 18, the bolt 17 and nut 18 can be easily removed from the outer casing 11, making it easy to remove the shovel plate 10 for maintenance and replacement. This helps to ensure the normal use of the shovel plate 10 and facilitates maintenance and replacement.

[0030] like Figure 3 and Figure 4 As shown, the position of the first through hole 20 corresponds to the position of the second through hole 21, which facilitates the insertion of the bolt 17 into the interior of the first through hole 20 and the second through hole 21.

[0031] The working principle of this utility model is as follows: By setting a stainless steel filter screen 5, which is located at the top of the water collection tank 1, it is convenient to filter coal mine residue and stones in the seeping water. Then, by starting the motors 14 on both sides, the reciprocating screw 4 is rotated, which causes the outer ball nut pair 13 and the fixing sleeve 15 to slide left and right, thereby causing the shovel plates 10 on both sides of the side plate 12 to slide left and right, removing the coal mine residue and stones above the stainless steel filter screen 5 and discharging them through both sides of the water collection tank 1. This helps to prevent coal mine residue and stones from accumulating on the stainless steel filter screen 5 and causing blockage. When the shovel plate 10 is damaged and needs to be replaced, the bolt 17 and nut 18 can be easily removed from the outer shell 11 and the back plate 16 by rotating the nut 18, making it easy to remove the shovel plate 10 for maintenance and replacement. This helps to ensure the normal use effect of the shovel plate 10 and facilitates maintenance and replacement.

[0032] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model are implemented according to conventional methods in the art, unless otherwise specified or limited.
