Embodiment 1

[0026] This embodiment is a low water head energy harvesting device, such as figure 1 shown. This embodiment includes: a water diversion pipe 2 arranged at the upstream 1 of the water flow, the water diversion pipe is provided with an air intake facility 3, and the water diversion pipe is connected to a gas-collecting facility 10 arranged at a water level 8 lower than the water flow downstream. The outlet of the water diversion pipe is arranged at the bottom of the gas-gathering facility, and the bottom or bottom of the gas-gathering facility is also provided with a water outlet 9, and the top or top of the gas-gathering facility is provided with an air outlet 6, and the gas outlet Connect air collecting pipe 5 on.

[0027] The basic idea of ​​this embodiment is: use the pressure difference between the upstream and downstream to collect and pressurize the air, then collect the pressurized air, and use the compressed air as the energy transfer medium. The minimum height diffe...

Embodiment 2

[0039] This embodiment is an improvement of the first embodiment, and is a refinement of the first embodiment regarding the water flow head. The water head of the water flow described in this embodiment is not less than 0.5 meters.

[0040] The water head of the water flow described in this embodiment is not less than 0.5 meters, that is, the energy of the water head at a height of half a meter can be collected to form compressed air.

Embodiment 3

[0042] This embodiment is an improvement of the second embodiment, and is a refinement of the second embodiment regarding the air intake facility. The air intake facility described in this embodiment is an air intake pipe.

[0043] There are many options for the position and installation method of the air intake pipe installed on the water diversion pipe. For example: the outlet of the intake pipe can be set on the pipe wall of the water pipe, such as figure 2shown. can also be as figure 1 As shown, the outlet is at the central axis of the water pipe, and the orientation of the outlet is consistent with the direction of water flow.

Abstract

The invention relates to a low water head energy collecting device and a low water head energy collecting method. The low water head energy collecting device comprises a water diversion pipe arranged at the water flow upstream, wherein a gas inlet facility is arranged on the water diversion pipe; the water diversion pipe is connected with a gas collecting facility arranged at the position lower than the water level at the water flow downstream; an outlet of the water diversion pipe is formed in the lower part of the gas collecting facility; a water outlet is further formed in the lower part or the bottom of the gas collecting facility; a gas outlet is formed in the upper part or the top of the gas collecting facility; a gas collecting pipe is connected with the gas outlet; a pressure control valve is arranged on the gas collecting pipe. According to the low water head energy collecting device disclosed by the invention, the gas inlet facility is arranged on the water diversion pipe, plenty of air is doped into the water flow; in the water flow falling process, the potential energy in the water flow is converted into flowing energy of air; the gas collecting facility is used for collecting air in the water flow, and converting the kinetic energy of air into compressed air, so as to convert the potential energy in the water flow into the energy for compressing air as far as possible, and improve the energy conversion efficiency; the low water head energy collecting device can efficiently develop the low water head hydraulic power energy, reduces consumption of the fossil energy source, and facilitates protection of the ecological environment.

Description

technical field [0001] The invention relates to a low water head energy collection device and method, which is a hydraulic device and method, and a device and method for producing secondary energy by using low water head energy. Background technique [0002] Rivers and lakes in nature, especially in plain areas, have a lot of low water head (water head less than 5 meters). The traditional way to collect energy is to build dams and form reservoirs, gather low water heads into industrially usable water heads, and then set up power generation A device that converts the energy of a water head into secondary energy. This method not only requires a lot of investment, but also destroys the local ecological environment, flooding a large amount of land in the upper reaches of the river, drying up the river in the lower reaches, and causing secondary disasters such as earthquakes and heavy rains. Traditional industrial power generation methods are difficult to use low water head to g...
