Abstract

The principle is shown in figure 1, where a wave enters from the left towards the float (10) which is lifted up and the wave proceeds inside the channel (1). Via the lever (9), which is stored in (13), the damper (3) is forced down and closes the channel (1). Figures 1 and 5 show the closed channel position. A shock results in a pressure increase in the wave, so that the check valve (5) opens and water flows through the opening (6) into the container (2). When the pressure decreases in the duct, the valve (5) will close the opening (6). The weight arm (9) goes down so that the damper (3) opens the channel again. This is repeated for every major wave that comes. Another alternative to the damper opening mechanism is shown in Figure 6. Here, the damper is thought to be opened and closed by a hydraulic cylinder (13). The actuator (5) may also be controlled by a hydraulic cylinder. The interconnection of (15) and (5) can then be programmed and controlled, for example, by means of a wave register. When the pressure is large enough in the container (12), the solenoid valve (11) opens and the water goes to a turbine for power production, possibly the water goes to a reservoir.

Description

Background

Transforming wave energy, for example into electrical energy, is an environmentally friendly process that comes under the term renewable energy. During the conversion, there is no emission of environmentally harmful substances such as C02(g). Arriving at good solutions is very important and extensive interest in the conversion of wave power has been expressed. The literature describes a large number of proposals for wave power plants, but as of today there are few solutions that can be considered economically profitable. The present invention relates to a device for transforming wave energy into mechanical or electrical energy is stated in patent claim 1. The invention further develops the principle of a shock sieve, which was invented in 1796 by the Frenchman Joseph Michel Montgolier. The present invention relates to a system that regulates an impact sieve that converts wave energy into pressure energy.

Detailed description of the invention

The principle can be seen from subsequent figures, figure 1 illustrates that water from a wave enters the channel (1) and enters a container (2) with the help of regulation units. When a wave enters the channel (1) from the left, the float (10) is lifted up at the same time as the outlet of the channel (1) is closed by a damper (3). The float (10) is fitted to a weight bar (9) at one end and a damper at the other end of the riser which is stored in (13), i.e. when the float (10) goes up, the damper (3) is forced down and closes the channel (1). The damper (3) goes down into a guide slot (14). See Figure 1 and Figure 5 which show the position when the channel is closed. The slot (11) is made to prevent the barbell from getting stuck. When the damper (3) is down, a shock occurs which causes a pressure increase in the wave, the valve (5) is opened and water flows through the opening (6) into the container (2). When the pressure decreases in the channel, the valve (5) will close the opening (6). The water in the container (2) goes out through a pipe (4) to a turbine or a higher reservoir. The pipe (4) is connected to a non-return valve which prevents water from returning through the pipe (4) into the container (2). The weight arm (9) moves so that the damper (3) opens the channel again and the valve (5) closes. This is repeated for each large wave that comes. The mechanism for opening and closing the valve (5) is a shaft (7) which is connected to the valve (5) at one end and a crank (8) at the other. The shaft (7) passes through the wall of the container (2), where a packing box seals around the shaft (7). The crank (8) is connected to a slot on the weight arm (9). Another alternative to the damper's opening mechanism is shown in Figure 6. Here, it is thought that the damper is opened and closed by means of a hydraulic cylinder (13). A pressure gauge (15) can be used to control the hydraulic cylinder, which can also be programmed and controlled, for example, using a wave recorder. The hydraulic cylinder can also help to reduce the time to close and open respectively damper (3) and valve (5).

Claims (1)

Claim 1. Device for transforming wave energy into mechanical or electrical energy, where the principle of the invention is a device that converts kinetic wave energy from ocean waves into potential pressure energy, this is done by guiding waves into a rectangular or circular channel (1), where the channel (1) is equipped with a closing device, a damper, (3) which can quickly close the entire channel cross-section, and this causes the kinetic energy to transfer to pressure energy where the increase in pressure causes the check valve (5) to open and lead the water into a container (2) that is filled and the water is pushed out via a pipe (4) where a non-return valve is fitted, when the pressure in the channel (1) is lower than the pressure in the container (2) the valve (5) closes, the channel is then completely open and a new wave can enter, the procedure is continuously repeated and transfers the water to a turbine that drives a generator for the production of electrical energy. Claim 2. Device according to claim 1 where the channel (1) can be closed and opened by means of two stored weight rods (9) which at one end are connected to a damper (3) and the other connected to a float (10), due to the buoyancy from the wave, which is on its way into the channel, the float (10) will be lifted up, and the damper (3) will go down and close the channel cross-section and a bottom valve (5) will be opened so that water flows into the container (2). Claim 3. Device according to claim 1 where the channel (1) and the valve (5) can be opened and closed using a hydraulic cylinder (13)
