Abstract

The invention relates to a hydraulic high-speed free piston linear generator and belongs to the field of energy power. The hydraulic high-speed free piston linear generator mainly comprises a free piston internal combustion engine, a hydraulic transmission mechanism and a linear generator, wherein the hydraulic transmission mechanism comprises a first hydraulic piston, a first hydraulic cavity, afirst hydraulic pump, a high-pressure oil pipe, a second hydraulic cavity, a second hydraulic piston and a second hydraulic pump; the connection relation in the hydraulic transmission mechanism is that: the first hydraulic piston is arranged in the first hydraulic pump, the second hydraulic piston is arranged in the second hydraulic pump, and the first hydraulic pump is communicated with the second hydraulic pump through the high-pressure oil pipe, so that the hydraulic transmission mechanism is formed; two free pistons of the internal combustion engine and the first hydraulic piston form a piston component through connecting rods; and an active cell of the linear generator is connected with the second hydraulic piston through another connecting rod. By adopting the hydraulic transmissionmechanism, the cutting speed of a motor active cell is increased and the working efficiency is improved; and the speed of the motor active cell is n times higher than the motion speed of the piston.

Description

technical field

[0001] The invention relates to a hydraulic high-speed free-piston linear generator, which belongs to the field of energy and power. Background technique

[0002] The general structure of the existing internal combustion generators is that the reciprocating internal combustion engine is connected with the rotating electrical machine through the crank connecting rod mechanism, including two types of thermal cycles of two strokes and four strokes. The disadvantages are complex structure, large volume, low thermal efficiency, and exhaust pollution. There are many things. Especially because the linear motion of the piston cannot directly realize the rotational power output, so it depends on the crank connecting rod mechanism to convert. The traditional crankshaft is mainly composed of crank, crank throw and crank pin. Its main feature is the stepped shaft section. During the working process, the piston The reciprocating inertial force and moment of inertia cause...
