Description

TECHNICAL FIELD The present invention relates to a pump device for pumping and sending water by utilizing wave energy generated in the surface of the ocean or lake.

[Problems to be Solved by Conventional Techniques and Inventions] A pump device for pumping and sending water is indispensable for realizing ocean purification, facility water for fish farms, marine farms, industrial water, drinking water and salt production plants. It is something.

There are various types such as an internal combustion engine, an electric motor, a steam turbine, and an air turbine that are currently used as a power source of such a pump device, but most of these energy sources are fossil fuels such as oil and coal. Either it is used or it uses nuclear energy.

However, such fossil fuels such as petroleum coal are thought to have limited reserves, are valuable raw materials resources for the chemical industry, etc. It should be avoided as much as possible to use it as a power source. Also, for the eternal descendants,
It is necessary to preserve this resource as much as possible.

Therefore, the present invention has been devised in order to effectively solve such a problem, and its main purpose is to effectively pump and pump water such as seawater without using the power source as described above. It is intended to provide a novel wave pump that can be operated.

[Means and Actions for Solving the Problems] In order to solve the above problems, the present invention floats on a water surface,
A float that moves up and down with the rise and fall of the water surface, a saddle fixed to the water bottom below the float, a ring body swingably supported by this saddle, and the ring body swing direction. A cylinder oscillatably supported in the intersecting direction, a piston reciprocally provided in the cylinder and partitioning and forming a pump chamber in an upper part of the cylinder;
While connecting the chain connecting the float and the piston, the pump chamber in the cylinder and the water storage side,
When the piston rises, it connects the water pipe that sends water in the pump chamber to the reservoir side through the check valve and the pump chamber in the cylinder, and when the piston descends, the pump chamber is connected through the check valve. And a water supply pipe for sucking water in.

Since the present invention is configured as described above, first, when the float floating on the water surface rises as the water surface rises, that is, as the waves rise, the piston connected to this float via a chain rises. Move in a direction of compressing the pump chamber in the cylinder, which increases the water pressure in the pump chamber. Then, the check valve of the water supply pipe connected to this cylinder is opened, and the water in the pump chamber passes through this water supply pipe and is sent to the water reservoir provided on the water surface or the like. Next, when the float descends as the wave descends, the chain slackens and the piston descends due to the weight of the piston, and the pressure in the pump chamber decreases. Then, the check valve of this water supply pipe closes and water supply to the water storage section and its backflow stop, and at the same time,
The check valve provided on one of the water supply pipes connected to this opens, and after the water flows into the pump chamber from this water supply pipe,
As the float rises again, as described above, the water taken into the pump chamber passes through the water supply pipe and is sent to the water reservoir. Then, by repeating such a vertical movement of the float, the water at the tip of the water supply pipe is sequentially sent to the water storage section side.

In addition, as described above, this cylinder is pivotally supported in the ring body pivotally supported by the saddle in a direction intersecting with the pivot direction of the ring body. Can be moved in almost all directions. Therefore, even if the float floating on the water surface moves from directly above the cylinder due to the tidal current or wind, the axis of the cylinder oscillates in the direction of the float and follows it, so that the attractive force of the chain accompanying the rise of the float While effectively transmitted to the piston side, the bending action of the piston rod is also reduced.

Further, a water passage is formed inside the ring body, and the water passage and the pump chamber are communicated with each other via a shaft portion that swingably supports the cylinder on the ring body, and the water passage, the water supply pipe, and the water supply pipe. By connecting the ring body to the saddle through a shaft portion that swingably supports the saddle, the communication of the water supply pipe and the water supply pipe with the pump chamber of the cylinder can be easily performed without adversely affecting the swing of the cylinder. To be done.
