[0013] A device for adjusting the liquid level of a water pool by using the siphon principle comprises a compressed air inlet valve 1, a pressure gauge 2, a compressed air filter 3, a vacuum generator 4, a vacuum breaking door 5, a vacuum generator exhaust pipe 6, a vacuum pumping pipe 7 and a water pool connecting pipe 8, wherein the water pool connecting pipe 8 spans over two water pools, and the pipes at both ends of the water pool connecting pipe 8 are respectively extended to below the liquid levels of the two water pools; the vacuum pumping pipe 7 is welded to the middle part of the water pool connecting pipe 8 and the other end of the vacuum pumping pipe 7 is connected to the negative pressure end of the vacuum generator 4; the air outlet end of the vacuum generator 4 is connected to the vacuum generator exhaust pipe 6, the air inlet end of the vacuum generator 4 is connected to the air outlet of the compressed air filter 3, the air inlet of the compressed air filter 3 is connected to the compressed air inlet valve 1, the pressure gauge 2 is arranged on the air inlet pipe of the compressed air filter 3, and the vacuum breaking door 5 is arranged on the water pool connecting pipe 8.

[0014] The water pool connecting pipe 8 is installed across the two water pools through a plurality of pipe supports 9 to prevent the water pool connecting pipe 8 from sinking.

[0015] The water pool connecting pipe 8 is arranged on the two water pools at a slope of 3‰.

[0016] A pressure gauge 2 is welded on the air inlet pipe of the compressed air filter 3 to indicate the air inlet pressure, which is used to adjust the vacuum pumping speed. The air inlet of the compressed air filter 3 is connected to the compressed air inlet valve 1 to control the start and stop of the vacuum generator 4.

[0017] A vacuum breaking door 5 is welded on the water pool connecting pipe 8 to stop the equipment.

[0018] In the embodiment, when the utility model is started, the vacuum breaking door 5 is closed.

As the air in the water pool connecting tube 8 is discharged, the liquid levels of the two water pools will gradually fill the water pool connecting tube 8, and a siphon will be formed between the two water pools. When the vacuum generator exhaust pipe 6 starts to discharge water, the compressed air intake valve 1 is closed to achieve automatic water level adjustment.

[0019] When the utility model is stopped, the vacuum breaking door 5 is opened, the vacuum in the pool connecting pipe 8 is broken, and the utility model is stopped.
