Description

Wave-powered water pump 73048

By cleavage separated from application 832723 -utbruten frän ensökan 832723.

The invention relates to a water pump which is powered by the wave motion of a lake or the sea.

For example, a wave pump is known, in which the pump is attached to a pier or the like and in which the work required for pumping is performed by a float at the end of the arm leaving the pump. The problem with such a pump, in particular, is that it requires a very high wave to operate and is thus best suited for use on the seafront.

The state of the art is also represented by Finnish Patent No. 50809 and German Patent Publication No. 1900544.

In the former, the work is accomplished by the so-called through space cells. The cell consists of horizontal and vertical elements. Raken-15 they form a rather large cell, and it is only suitable for use in power plants, ie as very large units in the Power Seas. The latter invention is also based on the utilization of vertical movement, i.e. it has stem floats which are sent up and down by the water. This operation also requires 20 large waves, and it cannot be properly utilized, for example::: In Finnish inland waters.

- · - [The device according to the invention is characterized by what appears; . ·. from the characterizing part of the claim. The device starts to work in a very small wave, about 10 cm high, when 25 devices are most often available, for example, on summer lakes and there are no villas in summer cottages. The maximum power is reached in a wave of about 40 cm, in which case, in practical experiments, about 1 liter of water is pumped per minute to a height of more than ten meters. The wave pump according to the invention is powered by the horizontal movement of the waves, the operating principle of which is substantially different from that of the prior art devices described above. The same wave motion causes, for example, the reeds to sway.

In the following, the structure of the pump will be explained in detail with reference to the accompanying drawings. Figure 1 shows the pump in the pumping stage and Figure 2 in the suction stage.

The wave pump comprises a working cylinder (5A), plates (4A), (4B) located at the ends of its cylinder part and 5 piston rods, flow ports (1A), (1B) with float valves, a float (2B), a clamping wire (9A) and a clamping point, e.g. platform (10A).

The plates (4A) and (4B) are fixed to the cylinder (5A) at an angle so that the plates are tilted as if in the direction of the wind. The wind direction is from left to right in the situation shown in the pictures. In the situation according to Figure 1, the corrugated brush (3A) is in front of the plate (4A), whereby water flowing from left to right pushes the plate (4A) with it. In this case, a compressive force is generated in the cylinder and the piston (5A) and the piston is pushed onto the cylinder si-15, whereby the water inside the cylinder is forced to flow through the non-return valve of the flow channel (1B) to the application. The non-return valve of the second flow channel (1A) is then closed. At the same time, the water mass (7B) moving from right to left pushes the plate (4B) forward, whereby the pumping-20 ho is kind of doubled.

In Fig. 2, the corrugated ridge (3A) has taken the plate (4A), whereby the right-to-left water mass (7B) on the right side of the plate pushes the plate to the left. In this case, the working cylinder performs the suction movement by sucking water through the non-return valve of the flow channel 25 (1A). The valve of the second flow channel (1B) is then closed. At the same time, the wave (3A) pushes the plate (4B) forward, whereby the pumping power is improved.

A prerequisite for the proper operation of the device is, in particular, that the plate (4B) is, as shown, in an oblique position relative to the cylinder 30 (5A). The flow of water in the wave takes place from the bottom up towards the ridge of the wave, from where the water flows as if along the sides of the brush down to the left and right. Thus, in the situation of Figure 1, a force resultant is applied to the plate (4B), which is formed by upward and leftward flows and forces the plate to move from right to left. If the plate were at right angles to the cylinder (5A), the force component resulting from the vertical flow would obviously have no effect.

Correspondingly, in the situation according to Fig. 2, the water flowing from the top of the corrugation brush meets the plate (4B) approximately perpendicularly, whereby the force pushing the piston to the right is at its maximum. The plate (4A) should also preferably be in an oblique position, as shown in Figure 5. In this case, in the situation according to Fig. 1, the flow of water from left to right meets the plate approximately perpendicularly, whereby the force is also greatest. In practice, the best result is obtained when the plate (4B) is at an angle of about 45 ° to the cylinder (5A) and the plate (4B) is at an angle of a few degrees with respect to the cylinder (5A), as shown in the figure. By changing the angle of the plates, it is also possible to influence the pressure and flow rate of the pumped water. The more upright the plates are, i.e. the closer the angle between the plates and the cylinder is to the right angle, the higher the pressure and the lower the flow and the shorter the working movement of the cylinder piston. Correspondingly, the flow rate increases, and the pressure decreases the more oblique the plates are.

The invention has been described above with reference to a preferred embodiment thereof. However, this is in no way intended to limit the invention to this example only, but many modifications are possible within the scope of the inventive idea defined by the following claim.
