Abstract
A floating cylinder (2) is driven up and down by sea water waves (1 ). Said floating cylinder (2) actuates a submersed non return valve (7) and a flexible tube (8) and pumps water in a fixed tube (5) up to a water tank (4).
Description
USING SEA WAVES TO GENERATE POWER
Technical Field:
Power Generation
Background Art:
Nothing
Disclosure of Invention;
Using the sea waves to push up quantity of water (Q) to height (H) which can be used to fall down to produce power.
WATER PULLING SET TWPS)
Drawing (1-1) is showing the (WPS) as a set, and drawing (1-2) is showing the items consisting the (WPS).
1 - wave ( 1 ) is pushing up the floating cylinder (Fl) -it is an empty closed cylinder - for height (W)
2- When (Fl) go up it pull the movable part (3) up -(Fl) is connected to movable part (3) with the coupling (4)
3- Movable part (3) is sliding on the fixed pipe (5) which allows sliding up and down as per drawing.
4- The lowest part of the moving part is item (6) , it is connected to the non return valve item(7) .it pull item (7) up and item (7) push item(8) - the diaphragm- up.
5- When item (8) go up the water pressure increases. The pressure close item (J) and open item (9) which are fixed to the pipe forcing the water to go up in the pipe (H) height.
6- When (F) goes down -after the wave pass- all the moving parts go down and the pressure inside the diaphragm go down making item (7) open and item (9) closed and water go in.
7- Repeating this gives quantity of water (Q) at height (H).
The (WPS) is related to some parameters:
- The floating cylinder (F) its diameter (Dl) and its length
(L).
-the wave height (W).
ASSAMTIONS:
L (the cylinder length) = 400 cms
D 1 (the cylinder diameter) = 100 cms
D2 (the fixed pipe diameter) = 50 cms W ( the wave height) — 60 cms
Nl ( number of ^ waves in min.) = 10 wave N2 ( number of WPS in system) = 4 wps
__ TT(Pl)2 XL
= 12571 kg
This force is the act of the wave on the cylinder.
Force 1 is the same force pushing the water in the fixed pipe up with height (H).
ττ(D2)2 XH Force 1 = 12571 kg = ±m Q
12571X1000
H = ^n ^n = 1599 cms
TT XSO XSO
To know the quantity of water (Q)
π(D2)2 XΪV jτXSOxSO xόG Q = 1000 1000
=471 litre
Considering 10 waves / min
471 X10
Q = — ^ = 78.5 1/3
So we have (Q) = 78.5 LfS
at height (R) = 16 M
Note 1 :
Item (10) is a submersed balloon connected to the moving part. The force of this balloon is nearly equal to the load of the moving part.
(Force of balloon is little less than the load of moving part to allow it to go down)
Note 2:
The height (H) in design should be little less then the result of (H) in the equation to allow (F) to go up.
HOW TO USE:
A STEEL BASE (PLATFORM) TO BE IN THE SEA IN A PLACE WITH SUTABLE WAVES AS PER DRA WING (2). FIXED ON THE BASE THE (WPS) WHICH IS PULLING WATER TO THE COLLECTING TANK AS DRA WING (3) THE WATER DROPES FROM THE TANK (Q). THE TANK HIGHT IS (H). THE (Q5 H) IS PRODUCING ELECTRICTY BY A WATER TURBIN AND ELECTRIC GANERATOR.
EXAMPLE FOR 75 KW POWER STATION:
L = 600 cms Dl = 80 cms D2= 45 cms W= 80 cms Nl = 12 wave/min
