Abstract

A wave power generator comprises a housing 1 inside which there is a counterweight 3, when the housing rocks due to wave action, relative movement between the housing and the counterweight cause gears to rotate and drive a generator. The housing has a tip cylinder 12 and a hollow section on his back, both reacting to restore the housing to its equilibrium position after displacement by a wave. The housing is fixed by mooring cables 22 through a universal joint. Details of the drive (ratchets, epicycle gear box, grip rollers, clutch and coil springs) are disclosed (figures 3 and 4). <IMAGE>

Description

Wave power generator The present invention related to converting energy of ocean wave to useful electrical energy.
many devices have been designe and proposed in' the past but the devices become complicated and expensive the propose of this invention is to convert the move ment of waves with a very simple way to electrical current.
Detailed description of apparatus.
In- acrdance with the drawings the apparatus is comp rive; an heart shape housing Fig 1 part 1, which is connected to a cylinder 2 and from the tip to another cylinder 40, both is closed with a cap 36 and 12 inside of main cylinder is a butterflyX1shape counterweight 3 which is rotate,aroundathe shaft 10 with a series of fixed bearings 11 ,nearip 100 degree.
Inside of the counterweight there is a chamber which all the gears, mechanism and generator is working, when this housing is floated om the surface- of' water due to the shape and location oft centre of gravity of apparatus will stay nearly 10 to 15 degree inclained see fig 1 by adding more weight to the location of P' or P we can adjust to reach the above position, now if the wave push the 'wing or head of the apparatus the weight of p' which will immerse ins the water come lighter and the housing will rotate around the counterweight 3 until goes up to a certain degree which the hollow part C immerse in the water then the back side of apparatus come lighter and due to the weight of p' and aleo shortage oft the wave will force the apparatus to come back to his normal position see fig 2, we can fill the counterweight cages 3 and the tip cylinder 40 with water or with some concrete.
As we described before both side of main cylinder 2 is covered with blank cap '36 inside of both cover there is two big spur gears 4 which is attached to the cover, when the housing is rotate around the counterweight 3 , this two big spur gears will rotate and mechanicaly will runl two small spur gears 5 im both side, see fig 3 (schematic of gearing mechanism) this two small gears is fixed in motionless counterweight, by adding' in one side gear 6 and gear 33, we can obtain one way rotational movement im both up and down of housing, connected to the gear 6 in one side and gear 5 jin other side to the shaft 34 there is two disks 14 and 15, which will run a series of pawls 26 and 27 between this two disk is fixed two ratchets 29 and 32 and also one winding gear 8 with fixed pawl 31 and ratchet 28 , all this parts is in one piece, when two outside ratchets rotate they will rotete and wind the middle spur gear 8, this gear will rotate gear 9 and afterward the winding coil spring 16 to store mechanical energy, then through slip clutch 17 and to the epyciclic gear box 18 to increase the speed and thereafter to the generator 19 to produce electricity. See Fig. 1 and 4 Instead of that three ratchets we can use freewheel with grip rollers see fig 3 side part.
Also instead of winding coil spring we can use compression type spring 46 with differential gears 45 Bee fig 4.
Electrical outlet of generator can pass through hollow part of main shaft 24 and to the rotational brush to the outside of apparatus. See Fig. 1 To prevent the apparatus to move beyond the working position, first the shape and location of the centre of gravity of apparatus will keep the housing in working position second if apparatus passed his normal position the hollow part of the housing C immerse in the water and react to bring apparatus again in normal position, and afterwards there is two stop bars 25 which will hit mooring cable 22 it both side and stop further movement, we can also use two cushion with the stop see fig 2 parts 25, this two cushion with the shape of "VOLUTE "will come off centre and effect the apparatus to immerse more' int water therefore will force the apparatus again to come in his normal position.
Both side of main shaft 10 is covered with the caps 13 and all the parts and mechanism is working inside of a sealed housing, also because is working with very low speed therefore we can lubricated properly to have a long life service.
Apparatus is partly immersed in the water and attached in both side to the mooring cables 22 with the universal joint 21 which will hold the apparatus in one position in the sea' or as described before can passed over the two cushion 38 to prevent over movement.
Mooring cables 22 is attached with the degree 30 or less to the sea bed therefore apparatus can goes up and down when the tide change.
FIG. 1 Show the side and sectional view of apparatus im normal position.
FIG. 2 Sketch showing the apparatus during the action of wave.
FIG. 3 Show the schematic prespective view of gearing mechanism.
FIG. 4 Show the schematic prespective view of energy storage device with differential gears.
