Abstract

Provided is a hydraulic rocker arm plate wave power device. The hydraulic rocker arm plate wave power device is composed of a generator, a double-rotor hydraulic motor, a guide pipe, a two-way hydraulic pump, a rocker arm, a blade plate, and a floating pipe rack. The double-rotor hydraulic motor is arranged on a generator shaft. The double-rotor hydraulic motor is communicated with a high pressure oil tank and a low pressure oil tank through a conduit, and the double-rotor hydraulic motor is also communicated with the two-way hydraulic pump through another conduit. The rocker arm and the blade plate are arranged on the two-way hydraulic pump. The impact force from waves to the blade plate drives the two-way hydraulic pump to pump oil to the tube, and then pushes the double-rotor hydraulic motor to drive the generator to produce electricity. All the parts are mounted in the floating pipe rack to work in a sealed mode. Both front-back translation force and up-down vibration force make a rocker arm plate drive an oil pump to pump oil, and push the double-rotor hydraulic motor to drive the generator to produce electricity. When the hydraulic rocker arm plate wave power device is installed, the hydraulic rocker arm plate wave power device is dragged into water and an anchor is dropped, and the electricity can be produced.

Description

Hydraulic rocker Lamb wave electric installation

Technical field: a kind of hydraulic rocker Lamb wave electric installation that utilizes wave power to generate electricity.Large-scale electronic product.

Background technique: existing wave power generation technology has many, and wherein 20 multinomially carried out sea trial.Apparatus for generating electricity by wave force mainly is divided into two kinds: mode of vibration (wave up-down vibration); Translating type (wave translation).Mode of vibration comprises 4 kinds, water column type, buoyant form, fixed, movable type.Movable is exactly the low water head generating.Commonly used is vibration water column type, the similar air compressor of its energy conversion principle.Transfer process is divided into 3 types substantially: the air energy: wave energy is converted to air, then drives turbo machine drive generator; Mechanical energy: wave power is converted to mechanical energy by the oil pressure actuated motor and drives generator; Water potential: the bucket that floats on the surface is elected in ashore reservoir by wave, utilizes the water-head on reservoir and sea to generate electricity.A kind of wave energy receiving machine is separately arranged, and application number 56104768A, this device are a kind of semicircle vertical impeller machines that is mounted to longitudinal arrangement with arc-like sheet on a vertical shaft, can receive in the ocean in the wave from peripheral direction and hit power.But this device only has half work, and second half is wasted work.Thereby useful work is very little.Drive generator with air, oil pressure, transfer process is complicated, and efficient is low, and this class device adopts can area too littlely, is difficult to obtain high-power electric.Similar bucket passes through ashore water lift warehouse-in of wave power, and the recycling water-head is generated electricity and produced little effect especially.Scan wave power generation all, the common factor that is difficult to promote the use of is: 1, the complicated efficient of conversion program is too low; 2, can only utilize a certain power (vibration or translation be a kind of power wherein) of wave; 3, cost is too high without the actual development meaning.4, can not be durable in use.How to reduce the conversion process of wave energy, the energy area is adopted in simplified structure, reduction cost, expansion, and improving working life is the precondition that the mankind utilize the wave energy of cleaning on a large scale.

Summary of the invention: a kind of hydraulic rocker Lamb wave electric installation is provided, and it is made of generator, double rotor fluid power motor, pressure-oil tank, low-pressure reservoir, conduit, bidirectional hydraulic pump, rocking arm, impeller, float tube frame.Load onto the double rotor fluid power motor on the main shaft of generator, for generator provides power, two soft conduits of double rotor fluid power motor communicate with pressure-oil tank, low-pressure reservoir and bidirectional hydraulic pump respectively.Rocking arm and impeller are housed on the piston of bidirectional hydraulic pump, and the end of impeller is upturned 20 °-30 °.Rocking arm and impeller can half-twist-180 °.Generator, double rotor fluid power motor, pressure-oil tank, low-pressure reservoir, conduit, bidirectional hydraulic pump, rocking arm conduit are installed in the float tube frame of sealing.Some groups are so installed vertical tandem or laterally arranged side by side, and all sealing is arranged on float tube frame interior (except impeller).Use the activity of soft rubber sleeve secure seal in the activity space of rocking arm and the relative movement of float tube frame freely.Impeller can rotate 180 °, and the end of impeller is upturned 20 °-30 °.Overall water displacement is slightly larger than gross weight, and is across the sea more floating in the time of making overall work.

No matter from the place ahead of impeller or during the rear impact impeller, impeller is subject to the power of up-down vibration or the power of front and back translation can make rocking arm rotate up when wave power.Different according to the peak valley height of wave, the rocking arm angle of swing is also different, and maximum can be 180 ° to the rear from the place ahead rotation.When rotating a certain angle, be subjected to the effect of energy-storaging spring that impeller is resetted.The proportion of impeller must not be too little, should be slightly less than 1, can continue work done when impeller is fallen after rise.When impeller, when rocking arm moves up and down, the pushing piston to-and-fro motion.The valve at bidirectional hydraulic oil pump two ends is realized work done pump oil along with the motion switch of piston.

High pressure oil enters pressure-oil tank by conduit, and oil and the pressurized air of certain reserves is arranged in pressure-oil tank, and the elasticity of air can continue oil pump is interrupted in short-term, guarantees that more stable high pressure oil is to double rotor fluid power motor fuel feeding.High pressure oil promotes the work done of double rotor fluid power motor rotor and drives coaxial generator generating.Low pressure oil after work done is through low-pressure reservoir (normal pressure) and the circulation of bidirectional hydraulic pump.

Beneficial effect: 1, cover the corrugated in certain marine site with (plastic-steel) impeller of cheapness, can adopt on a large scale energy.2, cheap without static investment; 3, moving element all seals, and is durable in use; 4, simply only installing to drop anchor, chain can obtain electric power; 5, auto-alignment wave direction.
