Energy-gathering hydraulic pressurization generating unit

Abstract

The invention discloses an energy-gathering hydraulic pressurization generating unit, which can make water and air pressurized. The generating unit comprises a water guiding system for storing the water, a power pressurization system for converting water energy into pressure energy, a buffering pressurization system for storing the pressure energy and a generating system for generating electricity by using the pressure energy, wherein the systems are connected with one another sequentially; the power pressurization system comprises a power water tank, a pressure object and a pressure cylinder which are connected with one another sequentially; the power water tank is used for receiving the water stored in the water guiding system; a water drainage device which is used for sealing the bottom of the water tank and has a water drainage effect is arranged at the bottom of the power water tank; the pressure cylinder comprises an internal pressure piston and an air inlet hole or a water inlet hole at the bottom; and a check valve is arranged at the air inlet hole or the water inlet hole. By the generating unit, the water energy is converted into the pressure energy, and the pressure energy is converted into mechanical energy for electricity generation, so that the influences of geographic environment factors is reduced to the minimum extent, and conversion efficiency is high; the power pressurization system has a simple structure and low construction cost and is developed flexibly; and the buffering pressurization system can sufficiently gather the energy and has high safety.

Description

technical field [0001] The invention relates to hydroelectric power generation, in particular to an energy-gathering hydraulic pressurized generating set utilizing water energy and air energy for pressurization. Background technique [0002] Hydropower generation is to use rivers, lakes, etc. to flow water with potential energy from high places to low places, convert the potential energy contained in it into kinetic energy of water turbines, and then use water turbines as the driving force to drive generators to generate electricity. Because traditional hydropower needs to use the potential energy of water, it has strict requirements on the terrain, and the water must be at a high place to have enough potential energy conversion to generate electricity, which brings the following disadvantages: [0003] 1. It is impossible to build a large capacity due to terrain constraints, and the capacity of a single unit is about 300MW; 2. The construction period is long and the constru...

Problems solved by technology

[0003] 1. It is impossible to build a large capacity due to terrain constraints, and the capacity of a single unit is about 300MW; 2. The construction period is long and the construction cost is high; 3. Because it is located in a natural river or lake area, it is vulnerable to Fengshui disasters and affects other water conservancy 4. It is not easy to increase the capacity after the plant is built; 5. Ecological damage: the erosion of water flow below the dam is intensified, the change of the river and the impact on animals and plants, etc.; Fertile alluvial soils are reduced by erosion
