Fig. 1 is a first embodiment of the present invention. As shown in fig. 1, the first pipe 1 is a circular pipe. The first pipeline 1 is a structure with two open ends, one end of the first pipeline 1 is positioned on the atmosphere side, and the other end of the first pipeline 1 extends to a position below the liquid level. Wherein, the bottom of the liquid level is provided with a sealed energy collecting device which is connected with the pipe orifice of the first pipeline 1 under the liquid level.

Specifically, a downcomer is mounted to the surface of the energy collection device. Wherein, three way connection is installed to the one end of downcomer, and three way connection's horizontal mouth of pipe is submerged by the upper reaches surface of water completely, and three way connection's perpendicular mouth of pipe extends to the atmosphere side. An air inlet pipe is arranged at the vertical pipe orifice, and the pipe orifice of the air inlet pipe is an air inlet hole of a sewer pipe. More specifically, when the upstream water flow flows into the energy collecting device through the sewer pipe, the air is rapidly downward flows into the energy collecting device through the water flow entrainment from the air inlet hole, and the air mixed with the water flow forms high-pressure potential energy in the energy collecting device, so that the high-pressure potential energy is provided for the first pipeline 1 to lift water upwards. Wherein, the difference between the upstream water level and the downstream water level is not less than 0.5 m.

Specifically, a first intake pipe 2 is formed at an intermediate position of the first duct 1. Wherein, the hole site of first intake pipe 2 one end is located below the liquid level, and the hole site of the first intake pipe 2 other end is located above the liquid level. The air inlet above the liquid level is used for receiving a pressure air source, and the device for providing the air source can be a common air pump or a manual air pump and the like. An air source is input into the first pipeline 1 through an air inlet, the water column in the first pipeline 1 is pushed to move towards the port on the air side through air pressure in the first pipeline, and the water column in the first pipeline gushes out from the port on the upper portion of the first pipeline 1.

Fig. 2 shows a second embodiment of the present invention. As shown in fig. 2, the water pumping device has a container 5 for containing water and a negative pressure container 6. Specifically, the container 5 and the negative pressure container 6 form a storage air pressure space for receiving the high pressure gas output by the energy collecting device, converting the high pressure gas into pumping power and conveying the liquid in the container 5 to a place with higher terrain.

A circular drain pipe 8 is installed at the junction of the negative pressure container 6 and the container 5. The pipe diameter of the drain pipe 8 is not limited, and is determined according to the actual drainage requirement.

Specifically, a circular negative pressure air exhaust pipe 7 is arranged at the top of the negative pressure container 6; the other end of the negative pressure exhaust tube 7 is provided with an air exhaust device. The air extractor vacuumizes the air pressure in the negative pressure container 6 through the negative pressure exhaust tube 7, so that the negative pressure strength in the negative pressure container 6 is increased, and the hydraulic lift of the drain pipe 8 can be increased.

In this embodiment, to enhance the flow monitoring of the pumping device, a sensor may be installed in the negative pressure tank 6. Specifically, the inductor is used for detecting the flow of the water column in the second pipeline 3, and the air exhaust device arranged at one end of the negative pressure exhaust tube 7 can be regulated and controlled by detecting the flow of the water column, so that the negative pressure in the negative pressure container 6 is within a controllable range, and the working efficiency of the water exhaust device can be improved.
