Description
Technical field
The present invention relates to a kind of hydraulic accumulation energy cylinder (or tank), particularly a kind of " the box-like hydraulic accumulation energy cylinder of magnetic spring-go (or tank) ".
Technical background
Its energy storage of hydraulic elastic energy storage cylinder (or tank) of development substantially all derives from the single energy " spring " at present, and the size of energy storage capacity depends on the elastic force of spring.But well-known, spring is fatal weakness of ubiquity all, that be exactly spring energy-storage be not the constant force energy storage---the initial pressure of-spring and the pressure difference that upper limit (UL) is pressed are sizable.Take Compress Spring as example, in elastic limit, when Compress Spring is compressed to the highlyest when spacing, the potential energy of its storage is more than the several times of initial elastic force.Like this, when elastic energy accumulation cylinder (or tank) is used for acting, certainly will just produce so obvious drawback: namely along with the progressively release of transmission fluid, elastic force is pressed also can become more and more less, the power that transmission fluid spreads out of also can be inevitably by dying down by force, the process utmost point that elastic energy accumulation cylinder (or tank) discharges transmission fluid is similar to the process that storage battery discharges electric energy, it so is the huge waste to loaded cylinder (or tank) confined space and transmission fluid, so, also just formed the intrinsic huge drawback of hydraulic elastic energy storage cylinder (or tank).Thereby alone spring (or other elastic material) realizes that hydraulic elastic energy storage certainly will affect the using effect of elastic energy accumulation cylinder (or tank).How to overcome this intrinsic drawback of elastic energy accumulation existence or how to realize in the finite volume of hydraulic elastic energy storage cylinder (or tank) that larger energy storage is that pendulum also is the major issue that need to need to be resolved hurrily in relevant researcher key subjects in front at present.
Experiment showed, in hydraulic elastic energy storage cylinder (or tank), depend merely on the quality that changes spring and pressure and mode and can't solve above-mentioned intrinsic drawback, only that is to say to can't resolve this root problem with a kind of mode of spring.Want in the finite volume of loaded cylinder (or tank), to realize higher energy storage, it " initially presses and maximal pressure " pressure reduction to change shortcoming greatly to overcome alone spring energy-storage, except improving spring-mass and optimizing the resilience energy memory structure, also must must be by means of the implantation of other energy.
" magnetic force " must be good application than clean energy resource as a kind of in actual life.At present, in world's fossil energy exhausted today progressively, magnetic force is the same with elastic force also to be to be worth us to promote and one of extraordinary clean energy resource of paying close attention to.Research finds, " magnetic force " and " elastic force " effectively to opposite application feature, and when namely two magnetic poles of magnetic force were away from must be more, gravitation or repulsion were less, otherwise then gravitation or repulsion are larger.If the two is used with, make it to produce composite force and jointly be applied in the same hydraulic accumulation energy cylinder (or tank), only just can overcome well with spring or only use the intrinsic drawback of magnetic force energy storage, and produce have complementary advantages, the mutual good energy storage effect of gram of disadvantage.So, magnetic force can be applied in the hydraulic elastic energy storage cylinder (or tank) simultaneously? experimental results show that it is fully passable.
After in elastic energy accumulation cylinder (or tank), implanting magnetic force, can from overcoming to a great extent the drawback that elastic force can successively decrease when discharging transmission fluid, can make elastic energy accumulation cylinder (or tank) produce the ideal effect of a kind of compound potential energy and composite power.The principle of its acting is: in elastic limit, spring is transmitted hydraulic pressure to the highest when spacing, and elastic force potential energy is the strongest, this moment two magnetic poles of attracting each other away from, thereby magnetic force is the most weak; Along with the progressively release of transmission fluid, elastic force can be more and more less, and two magnetic poles of attracting each other are more and more close, so magnetic force is just increasing, the maximum value of magnetic force is just in time corresponding with the minimum value of elastic force, and the maximum value of elastic force is corresponding with the minimum value of magnetic force.Like this, the adverse effect of the two just in time remedied mutually elastic force and magnetic force separately deficiency and reached a kind of more perfect composite power energy storage mode.
Summary of the invention

The objective of the invention is to realize by the following method: be somebody's turn to do by " the box-like hydraulic accumulation energy cylinder of magnetic spring-go (or tank) ", reach the hydraulic pressure cavity that is formed by cylinder (or tank) cylinder, piston, sap cavity cylinder (or tank) lid and the elastic force chamber formation that is formed by cylinder (or tank) cylinder, piston, bullet chamber cylinder (or tank) lid by cylinder (or tank) cylinder, piston, spring.Piston and sap cavity cylinder (or tank) cover be provided with can adelphotaxy magnetic pole, or piston and play chamber cylinder (or tank) cover be provided with can repulsive interaction magnetic pole.
For improving better the foregoing invention purpose, also can come in the following manner to be realized: magnetic pole all relative cylinder barrel vertically arranges; At piston and sap cavity cylinder cap or play to arrange on the cylinder cap of chamber and attract each other or single magnetic pole of repulsive interaction, also can correspondingly arrange and attract each other or many magnetic poles of repulsive interaction; Piston and sap cavity cylinder cap or bullet chamber cylinder cap can directly be made by magnet; The sap cavity mouth is arranged on the circle centre position of sap cavity cylinder cap and with one heart, liquid pressure injection Guan Keyu liquid releasing tube shares same sap cavity mouth; The elastic force chamber is a closed chamber, for adding the pressure in the strong elastic chamber, can be filled with pressurized gas.
