[0002] The goaf in a coal mine refers to the cavity or cavity left after the underground coal, coal gangue, etc. have been mined during the coal mining operation. Usually, after the coal mining operation is completed, a goaf will be left. If further deep mining is required, the goaf is generally moderately reinforced, and protective measures such as bolt fixation and wooden pile support are adopted. In a short time, the goaf in the coal mine will not collapse.

[0003] However, when the goaf is excavated to a certain depth, a large amount of accumulated water will appear in the goaf. In order to ensure the smooth progress of mining, the excess accumulated water needs to be drained out. However, most of the existing drainage methods are manually controlled. If the staff forgets or delays to turn on or off, the accumulated water will not only delay the mining construction, but may also cause accidents such as collapse when the accumulated water is serious.

[0023] The inner wall of the rotating seat 202 is rotatably connected to a swing rod 203, and the end of the swing rod 203 away from the rotating seat 202 is fixedly connected to a first buoyancy ball 204, the inner wall of the drainage box 201 is fixedly connected to a pressure switch 205, the upper surface of the water pump body 1 is fixedly connected to a power cord 5, the bottom surface of the water pump body 1 is fixedly connected to a water collecting tank 6, and the bottom surface of the water collecting tank 6 is fixedly connected to the upper surface of the buoyancy switch 213. The power cord 5 is provided to provide power supply to the water pump body 1, and the water collecting tank 6 is used to collect and suck away water.

[0024] The inner wall of the pressure switch 205 is slidably connected with a collision column 206, and the right side of the collision column 206 is fixedly connected with a spring 207. The end of the spring 207 away from the collision column 206 is fixedly connected to the inner wall of the pressure switch 205. The bottom surface of the water collecting tank 6 is fixedly connected with a filter screen 7, and the upper surface of the water collecting tank 6 is fixedly connected with a first connecting pipe 10. The filter screen 7 is provided to filter stone particles, and the first connecting pipe 10 is convenient for connecting to the output pipeline.

[0025] A rubber sheet 208 is clamped on the left side of the pressure switch 205, and a mounting ring 209 is fixedly connected to the left side of the rubber sheet 208. The end of the impact column 206 away from the rubber sheet 208 passes through the pressure switch 205 and the drainage box 201 in sequence and is fixedly connected to a linkage block 210. Three supporting legs 8 are fixedly connected to the bottom surface of the filter screen 7, and a placement pad 9 is fixedly connected to the bottom surface of each supporting leg 8. The cooperation of the supporting legs 8 and the placement pad 9 can prevent the water pump body 1 from sinking into deeper soil.

[0026] A contact 211 is fixedly connected to the left side of the linkage block 210, and a sealing plug 212 is fixedly connected to the left side of the linkage block 210.

[0028] The working principle of the utility model is as follows: when in use, the water pump body 1 is electrically connected through the power line 5, and the power provided by the water pump body 1 is used to collect water in the water collecting box 6, and then the water is transported to the inside of the drainage box 201 through the first connecting pipe 10, the hose 11 and the second connecting pipe 12. At this time, the buoyancy generated by the first buoyancy ball 204 can drive the swing rod 203 to float, and the floating of the swing rod 203 can open the two water flow ports reserved by the rotating seat 202, so that water can flow out from the reserved water flow ports. If the water supply flow rate is greater than the drainage flow rate at this time, the inside of the drainage box 201 will be filled with water. At this time, the rubber sheet 208 is pushed up by the water pressure, and the rubber sheet 208 is pushed up to push the collision column 206 to move. The movement of the collision column 206 can drive the linkage block 210 to move. At this time, the two contacts 211 are disconnected, and the sealing plug 212 is also opened from the closed state. At this time, water flows out from the drainage port 13;

[0029] If the water volume decreases at this time, the second suspended ball no longer presses against the waterproof trigger switch 214. The decrease in water volume will also reduce the water inside the drainage box 201. At this time, the pressure decreases, and the rebound force of the spring 207 is used to push the impact column 206 back, thereby driving the linkage block 210, the contact 211 and the sealing plug 212. At this time, the contact 211 contacts the waterproof trigger switch 214 to form a closed-loop control to stop the water pump body 1 from rotating and stopping water, thereby achieving the effect of automatic water pumping start and stop, and achieving the purpose of the intelligent coal mine goaf area water drainage pipeline automatic energy-saving drainage device, which can achieve the purpose of fully automatic water pumping start and stop without personnel supervision.
