A piston type water energy converter

Abstract

The invention provides a piston type water energy converter. The piston type water energy converter comprises at least two parallel cylinder bodies. The cylinder bodies share one crankshaft. The upper portion of each cylinder body is detachably connected with a cylinder cover. Each cylinder cover is provided with a water inlet valve and a water outlet valve. When a piston in one cylinder body is located at the upper stopping point, the corresponding water inlet valve is opened, high-pressure water flow is injected into the cylinder body to push the piston to move downwards for acting, the piston is connected with the crankshaft with one end connected with a flywheel, and the flywheel externally outputs kinetic energy; and when the piston moves downwards to a lower stopping point, the water inlet vale is closed, and meanwhile the water outlet valve is opened. Then, the piston in the other cylinder body is located at an upper stopping point, the piston moves downwards to do outward acting, the piston in the cylinder body moves upwards to the upper stopping point to discharge the low-pressure water flow, and circularly, the potential energy of water is converted into mechanical energy; and the power generating efficiency of a mini-type hydroelectric generator and voltage stability during load changing are improved.

Description

technical field [0001] The invention belongs to the field of hydropower generation, and in particular relates to a piston type water energy converter. Background technique [0002] The mainstream hydroelectric generators that are widely used now are in the form of impact type and counterattack type. Hydro turbine power generation uses the water turbine as the prime mover to convert water energy into electrical energy. When the water flows through the water turbine, the water energy is converted into mechanical energy. , the rotating shaft of the turbine drives the rotor of the generator, which converts mechanical energy into electrical energy and outputs it. It is the main power equipment for generating electrical energy in hydropower stations. The efficiency of large-scale generating units such as the turbines of the Three Gorges Hydropower Station can reach 90%, but the efficiency of micro-hydroelectric turbines averages about 70%, and the conversion efficiency is still un...

AI Technical Summary

Problems solved by technology

Micro-hydraulic generators are generally used in mountainous areas. Due to the high price of automatic water flow regulators, micro-hydraulic generators are generally not equipped with automatic water flow regulators. Manual water flow regulators are used to stabilize the voltage.

[0004] Therefore, it is very necessary to develop a low-cost and high-efficiency water energy converter to solve the problem of unstable power generation of micro-hydroelectric generators
