As shown in Figure 1, the construction of can coastal limit taking advantage of a situation of bed rearrangement sea wave power station is so that utilize Wave energy more easily.Wave 12 in the sea 14 moves up and down buoyant member 16.Buoyant member 16 links to each other with an end of steel chain 18, and the other end of steel chain 18 links to each other with load 20.Steel chain 18 is installed on the axle 22 by the ratchet 24 that is fixedly mounted on the axle 22.Steel chain 18 must constitute the form of bicycle chain, thereby when buoyant member 16 moved downward, steel chain 18 was with ratchet 24 engagements and drive ratchet 24.When buoyant member 16 moved upward, steel chain 18 can be thrown off and can not be driven ratchet.By this set, moving downward of buoyant member 16 will make axle 22 rotate in the direction of arrow A shown in Figure 1, and moving upward of buoyant member 16 will not make axle 22 carry out any rotation.

Axle 22 also has gear 26, and gear 26 cooperates with endless belt conveyer 28, thereby moves when making a rotation of spools 22 can cause line belt 28.Because 22 directions in arrow A of axle are rotated, so 28 direction motions of line belt in arrow B.A plurality of additional gear 26 ', be used for the motion of guide conveyor 28 along the path setting of line belt 28.For line belt 28 is moved more smoothly along its path, gear 26 " by line belt 28 " cooperates with gear 26, " rotates synchronously on same direction thereby make gear 26 and 26.In gear 26 " rotation help at line belt 28 through gears 26 " time, move downward.

Along line belt 28 a plurality of water pots 30 that move with line belt 28 are set.When water pot 30 moved into and shifts out sea 14 subsequently, water pot 30 had been filled seawater.When water pot 30 moves on to 30 ' time of position, water (with below with the mode of describing) is poured wet pit 32 into, and the position of wet pit 32 is than power station 34 height.The water pot 30 of turned letter water is sent the sea back to by line belt 28, also begins to send the water operation again thereby make water pot 30 fill water once more.

In order to obtain optimum efficiency, wet pit 32 had stored enough water before water flows into power station 34 downwards by water pipe 36.When water flow to power station 34 downwards, water was led to one or more turbine (not shown) and makes turbine rotation produce electric energy, and electric energy is transferred to the end user by electric wire 38 again.The potential energy of water is converted to the kinetic energy of water in the wet pit 32 when flowing through water pipe 36.The kinetic energy of water is converted into the kinetic energy of turbine again, is converted into the electric energy that is transferred to the end user subsequently again in a conventional manner.

Buoyant member 16 can be made by timber, metal, plastics, glass fibre, and can be arbitrary shape.As shown in Figure 3, buoyant member 16 can constitute square prism, has thickness identical upper strata 40 and lower floor 42, and wherein lower floor 42 is filled with water or other suitable liquid, and upper strata 40 is filled with air.The ratio of width of buoyant member (w) and length (l) and height (h), promptly w: l: h is preferably 1: 2: 1.Best, roughly 1/3 the height of buoyant member 16 exceeds the sea level.

The test that concerns between the weight of the water that has carried out the weight of relevant buoyant member and can transmit.As shown in Figure 2, ratchet 24 and gear 26 big or small identical, weight M is by line belt 28 ' cooperate with spools 22.Test result is as shown in table 1.

Buoyant member 16		Weight (M)
Buoyant member 16		Weight (M)		Weight (pound)	Displacement (x) (inch)	Weight (pound)	Displacement (y) (inch)
????5	????6	????1	????5	Weight (pound)	Displacement (x) (inch)	Weight (pound)	Displacement (y) (inch)
????5	????6	????1	????5	????5	????8	????0.5	????7
????5	????7	????0.75	????6	????5	????8	????0.5	????7

Have been found that most preferred ratio is 10: 1.5 between the weight of buoyant member 16 and weight (M), promptly 20: 3.The weight that this means buoyant member 16 is 1000kg, weight (M) that then can lifting 150kg, i.e. water.The frequency of supposing the upper and lower motion of wave is 15 times/minute, can obtain 2,250kg (15 * 150kg) the water of making a concerted effort to transmit.

As Fig. 4, shown in 5A and the 5B, bar 50 has two water pots 30, and each is near an end of bar 50.Two place's recess (not shown) are arranged on bar 50, respectively be used to hold the hook 52 that is connected on each water pot 30.Also be provided with the safety lock (not shown), be used for hook 52 is fastened to bar 50.By this set, water pot on being fastened to bar 50 safely in distaff 50 freely swing.Usually, water pot 30 presents the direction shown in Fig. 5 A and 5B, thereby when water pot 30 was filled water, water can not spill.As can be seen: bar 50 is fastened on the line belt 28, thereby makes bar 50 (and water pot 30) with line belt 28 motions.

Shown in Fig. 6 A and 6B, two blocks 54 are arranged in water pot 30 routes on the wet pit 32.Can be clearly shown that from Fig. 6 B the top edge of block 54 is positioned on water pot 30 bottoms.When water pot 30 contacts with block 54 and because travelling forward of line belt 28 and when further moving, water pot 30 is toppled over and poured the water of splendid attire into wet pit 32.Further travelling forward of line belt 28 crossed block 54 with the pulling water pot.

Since most of parts of the present invention all with contact with sea water, then require these parts made by the material of seawater corrosion by being difficult for, as stainless steel.

The present invention can also carry out various modifications certainly.As, can adopt buoyant member, and adopt different gear structures, so that improve the efficient of this equipment and send outlet capacity more than one.
