Embodiment 1
[0045] The present embodiment provides a kind of underground reservoir water level monitoring device, such as figure 1 As shown, it includes a water tank 200, a connecting pipe 301, a U-shaped pipeline 302 and a water level measuring assembly. Wherein the connecting pipe 301 runs through the connecting hole at the bottom of the dam body 100 of the underground reservoir, and the connecting pipe 301 is a cylindrical casing with a diameter of 180 mm, and the connecting hole is 200 mm away from the bottom of the reservoir. The U-shaped pipeline 302 is located in the underground water reservoir and the opening is set downwards. Its first end is used as a water inlet, and its second end communicates with the first end of the connecting pipe 301. The U-shaped pipe 302 opens Set downwards, when part of the gravel is inhaled, it will settle down under the action of gravity when passing through the downward section of the U-shaped pipeline opening, so as to prevent impurities and gravel...
Embodiment 2
[0053] The present embodiment provides a kind of underground reservoir water level monitoring device, on the basis of each scheme of the embodiment, also includes:
[0054] The high water level probe 402 is arranged in the water tank 200, and when the water level in the water tank is equal or exceeds its position, it outputs the first signal indicating that the water level is too high; it can use a pressure sensor, and its position can be It is set manually based on historical experience. Drainage pump controller 400, its first input end receives the signal output by the high water level probe 402, when receiving the first signal, the output end outputs a drainage control signal; A drainage through hole is provided; the drainage pump 401 can be a multi-stage pressure pump, its pumping end is connected to the drainage hole, and its control terminal receives the signal output from the output terminal of the drainage pump controller 400. After the control signal, start and run a...
Embodiment 3
[0064] This embodiment provides a method for monitoring the water level of an underground reservoir by the underground reservoir water level monitoring device described in Embodiment 1 or Embodiment 2. During specific application, a connecting hole can be punched directly at the bottom of the goaf underground reservoir dam body, the height of the connecting hole can be about 250mm, and the diameter of the connecting hole matches the diameter of the connecting pipe. Place the U-shaped pipe of the device in Embodiment 1 or Embodiment 2 in the underground reservoir and set the opening downward, extend the first end of the connecting pipe into the connecting hole, communicate with one end of the U-shaped pipe, and connect the other end of the connecting pipe One end directly extends into the inside of the water tank. Thus, the water in the underground reservoir enters the water tank through the connecting pipe, that is, the water tank and the underground reservoir are connected th...
