Detailed Implementation

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1-4 As shown, a mining underground drainage device includes a mobile vehicle 1. A water pump 2 is installed at one end of the top of the mobile vehicle 1, and a sedimentation tank 5 is detachably connected to the other end of the top of the mobile vehicle 1. A second outlet pipe 8 is connected to the top of the side wall of the sedimentation tank 5 near the water pump 2. A second inlet pipe 7 is connected to the middle end of the side wall of the sedimentation tank 5 away from the water pump 2. A first inlet pipe 4 is connected to the end of the water pump 2 near the second outlet pipe 8. A first outlet pipe 3 is connected to the end of the water pump 2 away from the first inlet pipe 4. A first connecting pipe 10 is provided at the end of the second inlet pipe 7 away from the sedimentation tank 5. The first connecting pipe 10 is located away from the inlet pipe. One end of the second 7 is fitted with a soft rubber tube 12. The end of the soft rubber tube 12 away from the second 7 is fitted with a connecting pipe 11. The outer wall of the connecting pipe 11 away from the soft rubber tube 12 is threaded with an internal threaded cylinder 14. The end of the internal threaded cylinder 14 away from the connecting pipe 11 is fixed with a filter screen 15. The top of the sedimentation tank 5 is equipped with a sealing plate 6. The bottom four corners of the sealing plate 6 are all fixed with pressure columns 61. The lower part of the pressure columns 61 is in contact with a mesh filter plate 62. The four corners of the inner wall of the sedimentation tank 5 located above the second 7 are all fixed with corner blocks 51. The top of the mobile vehicle 1 is fixed with an accessory box 9.

[0023] Specifically, the pressure column 61 and the filter plate 62 are respectively inserted into the sedimentation tank 5. The outer dimensions of the filter plate 62 match the inner dimensions of the top of the sedimentation tank 5. The bottom of the filter plate 62 contacts the top of the corner block 51. The sealing plate 6 and the top of the sedimentation tank 5 are detachably connected by bolts for easy disassembly and assembly.

[0024] Specifically, the two ends of the flexible tubing 12 are heat-fused to connecting tube 10 and connecting tube 2 11, respectively.

[0025] Specifically, several handles 13 are fixed to the outer wall of the connecting tube 2 11 near the soft rubber tube 12. The flexibility of the soft rubber tube 12 allows the staff to hold the handles 13 so that the connecting tube 2 11 can be aimed at the water accumulation area for precise suction.

[0026] Specifically, the inlet pipe 4 and the outlet pipe 8, as well as the inlet pipe 7 and the connecting pipe 10, are detachably connected by flange assemblies for easy assembly and disassembly.

[0027] Specifically, the sediment tank 5 is located below the water inlet pipe two 7 in a right trapezoidal shape, and the accumulated water discharged from the water inlet pipe two 7 can impact the inclined surface of the inner side wall of the sediment tank 5, so as to fall down.

[0028] Working principle: after the water pump 2 works, water is pumped through the connecting pipe two 11, and first needs to pass through the filter screen 15 for preliminary filtration. The preliminarily filtered sewage enters the inside of the sediment tank 5. The liquid level of the sewage in the sediment tank 5 gradually rises. In the rising process, some relatively large particles larger than the filter screen 15 can be deposited at the bottom of the sediment tank 5, thereby achieving an auxiliary filtering effect. With the rising of the liquid level, the sewage can overflow the filter screen plate 62 until the top of the sediment tank 5. The filter screen plate 62 can filter the rising sewage again, so that the impurities in the sewage passing through the water pump 2 can be greatly reduced, thereby achieving a better protection effect on the water pump 2. The sediment tank 5 and the sealing plate 6 are detachably connected through bolts. When the bolts are detached, the upward movement of the sealing plate 6 can drive the pressure column 61 to be extracted from the sediment tank 5, so that the filter screen plate 62 can be extracted from the sediment tank 5. The filter screen plate 62 can be replaced. The inner threaded cylinder 14 can be directly separated from the connecting pipe two 11 by rotating, and the clogged filter screen 15 can be replaced, so that the filtering effect is maintained. The filter screen plate 62 for replacement, the inner threaded cylinder 14 and the filter screen 15 can be directly placed in the accessory box 9, so as to be stored after replacement and disassembly.

[0029] The water storage tank can be placed in the electric locomotive on the nearby track. The accumulated water discharged from the water outlet pipe one 3 can be discharged into the water storage tank for storage. The full accumulated water can be directly transported to the discharge area by the movement of the electric locomotive on the track, so that the accumulated water does not need to be on the moving vehicle 1, thereby avoiding the increase of the weight of the moving vehicle 1.

Those skilled in the art should understand that the utility model is not limited to the above examples.
