Abstract
Disclosed is a hydraulic accelerating and reversing technology. Two hydraulic cylinders and a hydraulic motor form an accelerating system, and reciprocation rotation is converted into unidirectional rotation. The accelerating system is composed of a reciprocating power input rod, the hydraulic cylinders, the hydraulic motor, a plurality of check valves, overflow valves and pipelines and a liquid tank.
Description
Technical field
The present invention is the seawave power generation technology (patent No.: supplementing 201210152840.0), belongs to new energy development field.The speedup system of above-mentioned seawave power generation technology can adopt machinery speed increasing device and hydraulic speed increasing gear, but machinery speed increasing device is expensive, and weight is large.For this reason, propose to utilize oil hydraulic cylinder and oil hydraulic motor to form a kind of speedup reversing mechanism, alleviated structure weight, cost reduces greatly.The economic feasibility of above-mentioned seawave power generation technology is guaranteed.
Background technique
Due to the low frequency of wave, the power frequency ratio that general wave device absorbs is lower, in order to reach the generating rotating speed of generator requirement, all needs to carry out speedup.
At present, conventional speeder has: cylindrical gears speedup box, planetary gearbox and oscillating tooth speedup box etc., speed increasing ratio scope is generally 1-400.These speeders are machinery speed increasing device, at wind-powered electricity generation and machinery industry, are widely used.But after these speeders are applied on Wave power generation device, due to the low frequency of wave, the speed increasing ratio needing is very large, the progression of speedup is increased, box weight is large, expensive.
For this reason, the present invention proposes to adopt oil hydraulic cylinder and oil hydraulic motor to form speedup system, when meeting speedup commutation, and alleviator weight, reduce equipment manufacturing cost, guaranteed the seawave power generation technology seawave power generation technology (patent No.: economic feasibility 201210152840.0).
Summary of the invention
The present invention is the seawave power generation technology (patent No.: supplementing 201210152840.0), proposition forms speedup commutation system by oil hydraulic cylinder and oil hydraulic motor, by reciprocating power input bar, two oil hydraulic cylinders, an oil hydraulic motor, some one-way valves, relief valve, pipeline and liquid pool form, and above-mentioned hydraulic equipment forms oil hydraulic circuit.When input bar reciprocating rotation, drive the reciprocating motion of the pistons of oil hydraulic cylinder, promote liquid and form reciprocal pressure, then by hydraulic tubing, one-way valve adjustment, input to oil hydraulic motor, make oil hydraulic motor obtain single direction rotation.Within the unit time, oil hydraulic cylinder discharge capacity is several times of oil hydraulic motor discharge capacity, will obtain the speedup of several times, reaches the object of speedup.
This system is contemporary replaced seawave power generation technology (patent No.: the effect of tuning gear-box 201210152840.0), cancelled the tuning gear-box in this device, make device lighter and economical.
Accompanying drawing explanation
Fig. 1 is the oil hydraulic circuit that oil hydraulic cylinder and oil hydraulic motor form;
Embodiment
In Fig. 1, system is comprised of power input bar 1, oil hydraulic cylinder 2, oil hydraulic motor 3, liquid pool 4 and one-way valve 5, one-way valve 6, one-way valve 7, one-way valve 8, relief valve 9.
Input bar 1 middle part is hinged on fulcrum, and two ends are hinged with the piston rod of oil hydraulic cylinder 2 respectively, and oil hydraulic cylinder 2 bottom-hinged are on fulcrum.
When input bar 1 rotates counterclockwise, the piston compression of oil hydraulic cylinder in left side, liquid flows out from left side pipeline (chain line), by one-way valve 5, flows through oil hydraulic motor 3, in influent pond 4.The piston of right side oil hydraulic cylinder stretches, and liquid flows into the oil hydraulic cylinder of right side by one-way valve 8 from liquid pool 4.Now one-way valve 6 and one-way valve 7 are closed.
Otherwise, when input bar 1 clockwise rotates, the piston compression of the oil hydraulic cylinder on right side, liquid flows out from right side pipeline (dotted line), by one-way valve 6, flows through oil hydraulic motor 3, in influent pond 4.The piston of left side oil hydraulic cylinder stretches, and liquid flows into the oil hydraulic cylinder of right side by one-way valve 7 from liquid pool 4.Now one-way valve 5 and one-way valve 8 are closed.
And so forth, be no matter which oil hydraulic cylinder compression, the flow direction by oil hydraulic motor is consistent, makes oil hydraulic motor rotate direction identical, has reached the object of commutation.
The effect of relief valve 9, is when in-cylinder pressure surpasses the design pressure of setting, and opens relief valve decompression, to protect hydraulic system not destroy.
