High-efficiency fluid power generation device

Abstract

The invention relates to the technical field of power generation devices, and discloses a high-efficiency fluid power generation device. The high-efficiency fluid power generation device comprises a main cylinder body and two air cylinders, wherein side surfaces of two ends of a medium cylinder communicate with side surfaces of two ends of a piston cylinder through connecting tubes respectively; a piston is arranged in the piston cylinder; piston rods which are coaxially connected with the air cylinders are respectively arranged at two ends of the piston; liquid inlet one-way valves are respectively arranged at two ends of the medium cylinder; a liquid outlet channel is formed in the middle of the medium cylinder; liquid outlet one-way valves are respectively arranged on two sides of the liquid outlet channel; the outer end of the liquid outlet channel is connected with a liquid collecting cylinder; a liquid outlet tube is arranged on a side surface of the liquid collecting cylinder; a flow guide cover is arranged at the outer end of the liquid outlet tube; a turbine is arranged in the flow guide cover; a generator is arranged on the outer side of the main cylinder body; the turbine is connected with the generator through a turbine shaft; and the main cylinder body is filled with a liquid medium. The air cylinders drive the medium to flush on the turbine so as to drive the generator to generate power, the global stability is good, and the power generation efficiency is high.

Description

technical field [0001] The invention relates to the technical field of power generation devices, in particular to a high-efficiency fluid power generation device. Background technique [0002] Electric vehicles refer to vehicles that use electric energy to drive electric motors as power systems in whole or in part. It includes fuel cell electric vehicles (FCEV), hybrid electric vehicles (HEV) and pure electric vehicles (BEV). Due to the limited energy storage of batteries at present, pure electric vehicles have the problem of short driving range after one charge. Consider using a method of adding a range extender to pure electric vehicles to cooperate with the vehicle power battery to work under different working conditions, and increase the range of pure electric vehicles. The mileage of the car. The range extender is an additional energy storage component installed on the pure electric vehicle to increase the mileage of the pure electric vehicle. The range extender itself...

Problems solved by technology

The range extender is an additional energy storage component installed on the pure electric vehicle to increase the mileage of the pure electric vehicle. The range extender itself is a power generation device. The range extender usually includes a gasoline engine and a generator. The cylinder of the gasoline engine moves to drive The crank connecting rod mechanism makes the generator rotate to generate electricity. However, in the current power generation system with the structure of the cylinder and the crank, the crank bears a large impact force during the movement and reversing of the piston, which leads to energy loss and heat generation. Thereby reducing energy utilization, but also lead to reduced cylinder life

For example, the Chinese patent application publication number: CN103715828A, published on January 19, 2014, discloses a generator set for a vehicle-used power generation range extender. The generator set of this range extender uses a crank to connect the output mechanism, which consumes a lot of energy , large energy loss, and low generator efficiency
