Power conversion device

Abstract

The invention relates to a power conversion device, comprising a shell, a piston group and a crankshaft mechanism, wherein the shell is a rectangular tubular structure with two ends open; the two opposite inner walls of the shell are working surfaces and other two opposite inner walls thereof are sliding surfaces; each piston in the piston group has two working surfaces, two sliding surfaces and two combined surfaces; the pistons are arranged in parallel with the combined surfaces adjacent to each other to form the piston group; the piston group in the shell is arranged along the axle direction of the shell; each piston is provided with an independent piston rod with the same length; the crankshaft mechanism is arranged on the outer part of the shell; the crankshaft mechanism is composed of a crankshaft and a crank; the number of the crank throws on the crankshaft is equal to the number of the pistons in the piston group; each crank is connected with the corresponding piston rod. The advantages of the invention are as follows: the power conversion device combines the advantages of a reciprocating piston cylinder and a turbine; the power conversion device has characteristics of simple structure, simple manufacturing process and high power conversion ratio; the power conversion device can achieve large scale for equipments through modularization combination.

Description

technical field [0001] The invention relates to a power conversion mechanical device, which can efficiently convert fluid pressure and mechanical rotational force to each other, and belongs to the mechanical field capable of power conversion. Background technique [0002] According to the purpose, the power conversion mechanical device is divided into two categories: engine and propeller (pump); according to the structure, there are mainly two types of turbine (propeller) and reciprocating piston cylinder. These two different structures of power conversion devices can be used to manufacture Engine and propeller (pump). For example: reciprocating piston cylinders are used in both internal combustion engines and piston pumps; turbines (propellers) are used in wind and water engines as well as propellers and pumps. [0003] The principles and technologies of the above-mentioned power conversion devices have been publicly popularized in contemporary society, and mechanical equi...

AI Technical Summary

Problems solved by technology

The turbine is mainly composed of a casing, a rotor and blades. The advantage is that the structure is simple, and the cost of manufacturing high-power machinery is low. The disadvantage is that the power conversion is relatively low.

The reciprocating piston cylinder device is mainly composed of crankshaft, piston, and cylinder. The advantage is that the power conversion ratio is relatively high, but the structure is complicated, the machining accuracy of the components is high, and the manufacturing cost of large equipment is high.
