For the inexhaustible natural energy resources that utilizes wave to have, special proposition the present invention.

Main points of the present invention are to have proposed energy with wave to change the method for electric energy into and designed to realizing the concrete structure of the required device of this method.The present invention mainly is made up of the automatic adjustment system of buoyancy aid, spring, connecting rod, generator, substrate, fixing rod and substrate location.Substrate is fixed on the fixing rod and can keeps certain distance by the adjustment of automatic adjustment system and the surface of water, and generator then is fixed in the substrate, and the rotor of generator links to each other with connecting rod, and buoyancy aid and spring are being controlled the motion of connecting rod.When crest arrived, buoyancy aid made the rotor relative stator motion of generator make generator produce electric energy by the connecting rod transmission.Simultaneously, buoyancy aid does work to spring; When crest trough later comes interim, spring releases energy and makes the connecting rod return, and make the rotor of generator make generator for electricity generation once more with respect to stator movement, like this, along with ceaselessly transmitting of wave, generator just can ceaselessly generate electricity, if a plurality of such generator set is worked simultaneously, then can obtain bigger electric energy, finish task proposed by the invention.

Below in conjunction with accompanying drawing the present invention is elaborated

Fig. 1 is installation, the work schematic representation of single generator set.

Fig. 2 is that a plurality of generators are formed the arrangement mode of series in water.

Fig. 3 is translational electric generator structure (wherein (a) is sectional view, (b) is plan view).

Fig. 4 is a Lever type translation electric generator structure.

Fig. 5 is the rotary type generator Structure.

Fig. 6 is that the side view of several critical pieces of rotary type generator ((e) is the erection drawing of spiral spring wherein; (f) be electric machine structure; (g) be the mounting structure of connecting band).

The present invention has a substrate (4) that mainly is made of three slotted-angle shelvings, its two ends are enclosed within on the fixing rod (5), fixing rod (5) is processed with screw thread at the outer surface at certain position, and every end of substrate (4) all can be moved up and down and be moved by motor (6) the drive displacement nut (7) of each end outside thread along fixing rod (5).Be fixed with one that can move up and down with it and stretch out the quite movable rod (8) of height (wave can not wet top) of the water surface on the termination of substrate (4), fixing the enable switch of two motor (6) on movable rod (8), one for moving down switch (9).Another removes pass (10) on being, move down switch (9) and be the two poles of the earth in switching circuit loop, (because seawater conduction) connected in the loop when under water at ordinary times, motor (6) is not worked, when the water surface moves down, move down switch (9) when surfacing (11), switching circuit moves down with drive displacement nut (7) rotation because of the actuating motor that opens circuit (6) that moves down switch (9), until moving down till switch (9) immerses in the water; On remove the two poles of the earth that pass (10) then is one group of switching circuit not under water, no current is not worked by, motor (6) at ordinary times, when going up, the water surface (11) is dipped into when removing pass (10), switching circuit is connected, actuating motor (6) drives in displacement nut (7) rotation and moves, until on remove pass (10) and can not contact with water, like this, no matter the water surface goes up or the whereabouts, and substrate (4) two ends can both be adjusted.Substrate (4) is descended and water surface maintenance certain distance at the water surface (11).In addition, on remove pass (10) and move down on the masthead of the movable rod (8) that the lead of switch (9) should can not arrive from seawater and directly stretch down, with anticreep out of control, and the distance between two switches should rationally be determined according to the size of wave amplitude.

Generator (3) is installed in the substrate that can adjust up and down automatically (4), and by connecting rod (2) with produce the spring action campaign of A to power, keep afloat by buoyancy aid (1) by buoyancy aid (1) for the rotor of generator (3).Its water-immersed degree of depth should be as far as possible little, but the buoyancy that it is produced in water should be the A of spring more than the twice of the size of power, between buoyancy aid (1) and the connecting rod (2) is that hinge is connected, can do the inclination of several angle with the fluctuating of wave,, be arranged with in the substrate (4) a plurality of generator set (its orientation preferably with the wave propagation direction (B to, as Fig. 2) Vertical direction become a small angle, and make each buoyancy aid (1) B to distance be not the integral multiple of wave wavelength as far as possible, in order to avoid each buoyancy aid (1) because of the effect of wave synchronously to substrate (4) application of force).This system is when crest transmits, and buoyancy aid (1) is with the wave come-up, and it makes generator (3) produce electric energy by the rotor relative stator motion that connecting rod (2) drives generator (3), and to producing the spring acting of A to power; After the crest, trough comes temporarily, produces A and releases energy to the spring of power, make connecting rod (2) move down return, and drive the rotor relative stator motion of generator (3) once more and make generator (3) generating.Like this, native system constantly produces electric energy along with constantly transmitting of wave and has finished task proposed by the invention.

In addition, generator (6) can adopt multiple structure, below several structures is described:

Structure one: translational generator (as Fig. 3)

This structure is the bottom that permanent magnet (13) (rotor of generator (3)) directly is connected connecting rod (2), and coil (12) (stator of generator (3)) divides more than three groups.And the axial height of every group of coil (12) equals the movement travel usefulness of the axial length of magnet (13) with not unrestrained useless permanent magnet (13), connecting rod (2) is subjected to the effect of buoyancy aid (1) and extension spring (14), when no wave, permanent magnet (13) is parked in the stage casing of several groups of coils (12), when wave, buoyancy aid (1) and extension spring (14) make permanent magnet (13) move up and down in turn, thereby make coil (12) produce electric energy.

Structure two: Lever type translation generator (as Fig. 4)

Though structure one is simple, but the rotor stroke is shorter, can adopt Lever type translation generator for overcoming this shortcoming, its structure is that buoyancy aid (1) is done swinging up and down of certain radian by connecting rod (2) and extension spring (14) control one shrinking connecting-rod (16) around rationed marketing (15), shrinking connecting-rod (16) is the telescopic cooperating structure of a stock and long sleeve, it passes the guide way (18) (its permeance property bad) of guiding groove (19) manipulation in sleeve (17) of opening on sleeve (17) wall and moves up and down, the permanent magnet (13) that is connected guide way (18) bottom is moved up and down in coil (12), thereby produce electric energy (coil (12) also will be divided into and isometric some groups of permanent magnet (13), but total length is longer than structure one).

Structure three: rotary type generator (as Fig. 5 and Fig. 6)

This structure is that the rotor-permanent magnet (25) of generator (3) is contained in by bearing fixing on the axle (21) between two supporting rods (22), stator-coil (26) correspondence is contained on the fixing electric machine casing (23), supporting rod (22) and electric machine casing (23) are fixed in the substrate (4), two of spiral spring (24) is contained in respectively in axle (21) and the substrate (4), buoyancy aid (1) then directly by around the good connecting band of Qu Xingneng (20) around the axle (21) of ining succession, like this, buoyancy aid (1) does work to permanent magnet (25) in turn by connecting band (20) and spiral spring (24) under the effect of wave.Make its positive and negative rotation respectively, thereby make coil (26) produce electric energy (equal diameters of permanent magnet of this motor (25) and coil).

For example:if the crest of wave is higher than 50 centimetres in trough, the wave transmission cycle is 5 seconds, and the upper pulling force that buoyancy aid (1) is produced in wave is about 3000 kilograms, the A of spring is about 1500 kilograms to active force, then at this moment buoyancy aid (1) and spring are 1500 watts to the power that generator (3) is done work, reasonably select the permanent magnet and the coil of generator (3) for use, just can make generator (3) send electric energy about 1 kilowatt.If in a marine site, have 1,000 such generator set, 1000 kilowatts of this moment. of then just can obtain the generated energy of
