A limiting groove is formed on the inner wall of the connecting pipe, and a limiting ring is movably installed inside the limiting groove. A locating groove is formed on the inner wall of the connecting pipe near the limiting groove, and a locating ring is movably installed inside the locating groove. A movable pipe is fixedly installed at one end of the locating ring. This drainage device for coal mine goaf areas, as described in this utility model, uses a suction pipe to drive the movable pipe to rotate, causing the movable pipe to drive the locating ring to rotate inside the locating groove, thus preventing the drainage pipe from folding and quickly eliminating any folds in the drainage pipe, thereby ensuring water flow.

[0003] The existing technical solutions described above have the following drawbacks: In order to facilitate the movement of the water pump, the water pump is installed on a mobile cart. When the water pump is started, it will generate strong vibration force, which will cause the mobile cart to move, making it impossible for the water pump to work at a fixed point and reducing the stability of the water pump. Utility Model Content

[0004] To address the problems mentioned in the background art, the purpose of this utility model is to provide a drainage device for coal mine goaf areas, which has the advantage of stable operation. It solves the problem that when a water pump is installed on a mobile cart for convenient movement, the water pump will generate strong vibration when it is started, causing the mobile cart to move and making it impossible for the water pump to work at a fixed point, thus reducing the stability of the water pump.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a drainage device for a coal mine goaf, comprising a flatbed cart, a mounting frame fixedly connected to the top of the flatbed cart, a water pump fixedly connected to the top of the mounting frame, positioning toothed plates on both sides of the bottom of the flatbed cart, vertical rods fixedly connected to the front and rear sides of the top of the positioning toothed plates, the top of the vertical rods extending through to the top of the flatbed cart, and a control mechanism fixedly connected to the top of the vertical rods.

[0006] In a preferred embodiment of this utility model, the control mechanism includes a motor, which is fixedly connected to the bottom of the cart. The output end of the motor extends through to the top of the cart. A rotating plate is fixedly connected to the output end of the motor. Transmission plates are movably connected to both sides of the rotating plate. A push block one is fixedly connected to the outer side of the transmission plate. A push block two is provided at the bottom of the push block one. The bottom of the push block two is fixedly connected to the top of the vertical rod. The inner wall of the mounting bracket is in contact with the top of the push block one.

[0007] As a preferred embodiment of this utility model, the front and rear sides of the push block two are provided with limit strips, and the bottom of the limit strips is fixedly connected to the top of the flatbed cart.

[0008] As a preferred embodiment of this utility model, a tension spring is fixedly connected to the top of the positioning tooth plate, and the top of the tension spring is fixedly connected to the bottom of the flatbed cart.

[0009] As a preferred embodiment of this invention, the bottom of the motor is fixedly connected to a hanger, and the top of the hanger is fixedly connected to the bottom of the flatbed cart.

[0010] As a preferred embodiment of this invention, a stabilizing sleeve is fitted onto the surface of the vertical rod, and the top of the stabilizing sleeve is fixedly connected to the bottom of the flatbed cart.

[0011] As a preferred embodiment of this invention, a reinforcing block is fixedly connected to the bottom of the vertical rod, and the bottom of the reinforcing block is fixedly connected to the top of the positioning tooth plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a positioning toothed plate that can engage with the ground, allowing the cart to be stably positioned. The vibration force generated by the water pump cannot cause the cart to shift off the ground. When the cart needs to be moved, the motor is started, which drives the rotating plate to rotate. The rotating plate drives the transmission plate to move inward, and the transmission plate drives the push block one to move inward. Push block two loses the downward pressure from push block one, and the vertical rod and positioning toothed plate lose the downward pressure. After the positioning toothed plate loosens and separates from the ground, the cart can then move the water pump to a new position. This design has the advantage of stable operation, as the vibration force of the water pump cannot move the cart, thus improving the stability of the water pump.

[0014] 2. By setting up a control mechanism, this utility model can control the positioning tooth plate, avoiding the inability of the positioning tooth plate to press down stably, which would make it difficult for the positioning tooth plate to engage with the bottom, thus improving the working effect of the positioning tooth plate.

[0015] 3. By setting a limiting strip, this utility model can make the push block two slide stably, avoid the push block two from shaking during the sliding movement, and thus improve the sliding stability of the push block two. Attached Figure Description

The bottom of the push block 65 is fixedly connected to the top of the vertical rod 5. The inner wall of the mounting bracket 2 is in contact with the top of the push block 64.

[0024] As a technical optimization of this utility model, by setting the control mechanism 6, the positioning tooth plate 4 can be manipulated, avoiding the inability of the positioning tooth plate 4 to press down stably, which would make it difficult for the positioning tooth plate 4 to engage with the bottom, thus improving the working effect of the positioning tooth plate 4.

[0025] refer to Figure 2 Limiting strips 7 are provided on both the front and rear sides of push block 2 65, and the bottom of the limiting strips 7 is fixedly connected to the top of the board car 1.

[0026] As a technical optimization of this utility model, by setting the limiting strip 7, the push block 2 65 can slide stably, avoiding the push block 2 65 from shaking during the sliding movement, which would cause the push block 2 65 to loosen, thus improving the sliding stability of the push block 2 65.

[0027] refer to Figure 4 A tension spring 8 is fixedly connected to the top of the positioning tooth plate 4, and the top of the tension spring 8 is fixedly connected to the bottom of the board carriage 1.

[0028] As a technical optimization of this utility model, by setting a tension spring 8, the positioning tooth plate 4 can be pulled to automatically reset and move, avoiding the need for manual reset after the positioning tooth plate 4 is pushed and cannot automatically return to its original position, thus improving the ease of use of the positioning tooth plate 4.

[0029] refer to Figure 3 The bottom of the motor 61 is fixedly connected to the hanger 9, and the top of the hanger 9 is fixedly connected to the bottom of the flatbed 1.

[0030] As a technical optimization of this utility model, by setting the hanger 9, the connection between the motor 61 and the flatbed 1 can be reinforced, so as to prevent the motor 61 and the flatbed 1 from breaking during use, prevent the motor 61 and the flatbed 1 from being unable to cooperate, and improve the use effect of the motor 61 and the flatbed 1.

[0031] refer to Figure 4 A stabilizing sleeve 10 is fitted onto the surface of the vertical rod 5, and the top of the stabilizing sleeve 10 is fixedly connected to the bottom of the flatbed trolley 1.

[0032] As a technical optimization of this utility model, by setting the stabilizing sleeve 10, the vertical rod 5 can slide stably, avoiding shaking during the sliding movement of the vertical rod 5, which would cause the vertical rod 5 to loosen, thus improving the sliding stability of the vertical rod 5.

[0033] refer to Figure 4 A reinforcing block 11 is fixedly connected to the bottom of the vertical rod 5, and the bottom of the reinforcing block 11 is fixedly connected to the top of the positioning tooth plate 4.

[0034] As a technical optimization of this utility model, by setting the reinforcing block 11, the connection between the vertical rod 5 and the positioning toothed plate 4 can be reinforced, so as to prevent the vertical rod 5 and the positioning toothed plate 4 from breaking during use, prevent the vertical rod 5 and the positioning toothed plate 4 from not being able to cooperate, and improve the use effect of the vertical rod 5 and the positioning toothed plate 4.

[0035] The working principle and usage process of this utility model are as follows: In use, the positioning toothed plate 4 is pressed down in the figure. At this time, the positioning toothed plate 4 can engage with the ground, so that the pallet 1 can be stably positioned. The vibration force generated by the water pump 3 cannot cause the pallet 1 to shift on the ground. When it is necessary to move the pallet 1, the motor 61 is started. The motor 61 drives the rotating plate 62 to rotate. The rotating plate 62 drives the transmission plate 63 to move inward. The transmission plate 63 drives the push block 1 64 to move inward. The push block 2 65 loses the downward pressure of the push block 1 64. The vertical rod 5 and the positioning toothed plate 4 lose the downward pressure. After the positioning toothed plate 4 is loosened, it separates from the ground. The pallet 1 can then drive the water pump 3 to move its position.

[0036] In summary, the drainage device for the goaf of this coal mine, through the coordinated use of the trolley 1, mounting frame 2, water pump 3, positioning toothed plate 4, vertical rod 5, and control mechanism 6, solves the problem that when the water pump is mounted on a mobile trolley for easy movement, the pump generates strong vibrations when it starts, causing the trolley to move and preventing the pump from operating at a fixed point, thus reducing the stability of the pump.
