Description

Technical Field

[0001] The utility model relates to the technical field of drainage devices, in particular to a drainage device for a hydraulic support. Background Art

[0002] A hydraulic support is an important device used in underground mine mining operations. It is mainly used to support the roof of the mine and maintain the stability of the working face. It uses a hydraulic system to provide the necessary supporting force to ensure the safety and stability of the mine. During the mine mining process, the hydraulic support often encounters the problem of water accumulation. Therefore, the drainage device is crucial for the hydraulic support.

[0003] After retrieval, a drainage device for a hydraulic support and a hydraulic support with the publication number CN219865089U include an emulsion motor; a speed increaser connected to the emulsion motor; and a water pump connected to the speed increaser. The hydraulic support includes the drainage device described above; a first base connected to the drainage device; and a monitoring device connected to the first base. In this application, a drainage device is provided in the base of the hydraulic support, and a monitoring device for monitoring the water level of the working face is also provided. When the water level of the working face exceeds the set water level, the hydraulic support control system is turned on to supply liquid to the drainage device, causing the drainage device to start draining; the drainage device of this application is small in volume and does not occupy extra space underground in the mine. It uses the emulsion drive system of the hydraulic support to drive the drainage device, which is convenient to use and makes the drainage underground in the mine more convenient;

[0004] Based on the above patent, the drainage device starts draining by turning on the hydraulic support control system to supply liquid to the drainage device; the drainage device of this application is small in volume and does not occupy extra space underground in the mine. It uses the emulsion drive system of the hydraulic support to drive the drainage device, which is convenient to use and makes the drainage underground in the mine more convenient. However, when this device is in use, it is not convenient to replace the filter screen. Sediment and impurities in the water will gradually accumulate on the surface of the filter screen, resulting in blocked water flow and reduced drainage efficiency. Poor drainage will cause the water level to rise, thus affecting the stable operation of the hydraulic support. Moreover, after the water in the base is drained, there may be a situation where silt accumulates in the base. After long-term accumulation, it will affect the stability of the base and the supporting force of the hydraulic support, causing wear and corrosion to the components of the entire drainage device and the hydraulic support, thereby affecting the service life. Therefore, this application proposes a drainage device for a hydraulic support. Summary of the Utility Model

[0025] Further, the support body 2 is fixedly supported by the base 1. By opening the valve, the water accumulated in the base 1 can be discharged through the drain pipe 3. The square opening 4 limits the first fixing block 6. The first fixing block 6 fixedly supports the coarse filter screen 5. By placing the coarse filter screen 5 in the base 1, during the drainage process, the coarse filter screen 5 can filter and intercept the sediment and impurities in the water, preventing the sediment from blocking the drain pipe 3. The L-shaped rod 16 is fixedly supported by the shaft seat 15, and the limiting groove 19 limits the L-shaped rod 16.

[0026] Refer to Figure 3 , wherein grooves 9 are formed in the inner walls of the front and rear sides of the right end of the fixed seat 8. Both sides of the grooves 9 are connected to the connecting plate 12 through a plurality of first springs 10. The outer walls of both sides of the connecting plate 12 are arranged on the inner walls of the grooves 9. One ends of the outer walls of the first springs 10 are fixedly connected to the inner walls of the grooves 9, and the other ends of the first springs 10 are fixedly connected to the outer walls of the connecting plate 12.

[0030] Working principle: First, place the coarse filter screen 5 in the base 1 through the square opening 4. Then, press the connecting plate 12 to drive the connecting rod 11 and the clamping block 13. The connecting plate 12 enters the groove 9, and the clamping block 13 enters the through groove 7. The first fixing block 6 moves downward under the action of gravity, causing a dislocation between the through groove 7 and the clamping block 13, realizing the connection between the first fixing block 6 and the fixing seat 8. After that, open the valve on the front side of the drainage pipe 3 to drain the water in the base 1 through the drainage pipe 3. The sediment and impurities in the water can be filtered and intercepted by the coarse filter screen 5. When it is necessary to clean the silt in the base 1 later, pull the connecting blocks 22 on both sides to drive the clamping column 23 and the limiting plate 24 to move. The limiting plate 24 moves in the sliding groove 20, driving the clamping column 23 to disengage from the through hole 17 of the L-shaped rod 16. Then, rotate the L-shaped rod 16 so that the L-shaped rod 16 makes an arc movement with the connection point of the shaft seat 15 and the L-shaped rod 16 as the center of the circle, so that one end of the L-shaped rod 16 can disengage from the limiting groove 19, and the baffle 14 and the base 1 can be disassembled and separated, facilitating the staff to clean the silt in the base 1.
