Abstract

PURPOSE:To purify water by producing relatively high pressurized air in comparison to the height of wave using wave motion energy and feeding it into water. CONSTITUTION:A float 1 of a wave pump A is caused to rock to generate power utilizing wave motion energy to actuate a piston 5 in a cylinder 4 provided underwater. Water in the cylinder is delivered through a pipe 7. The moment the water is sent into a medium tank 10, water level in a water column 11 rises to a level greatly higher than the height of the wave, whereby the air in the column 11 is pressurized. Pressurized air thus produced passes through a check valve 16 and is delivered from a pressurized air delivery pipe 15 at the bottom of the water to the outside. The delivered air effects aeration actions due to the differences in specific gravities between water and air, so that oxygen is fed into the water and flows of water are generated at the bottom of the water, causing thereby purification of the water.

Description

[Detailed Description of the Invention] [Industrial Field of Application] This invention relates to a device that uses wave energy to purify water. The purpose of this invention is to use the inexhaustible kinetic energy of waves to generate pressurized air and send this air into the water to purify water. [Conventional technology] The power source for conventional purification equipment is electric power or an internal combustion engine, but most of these utilize energy sources such as oil, coal, and nuclear power. [Problems to be solved by the invention However, these resources will be used up in the near future, and it is necessary to treat these resources with care.

In other words, it is necessary to use natural energy such as wind, wave power, and sunlight if it is available. Next, ria coastlines, the backs of closed bays, and lake waters tend to become polluted and turn into sludge every year. Therefore, a time will come in the near future when these vast bays, inland seas, fish farms, or lakes will have to be purified. Also, regarding the problem of creating pressurized air using the power of waves, there are some devices that are currently in practical use in the field of wave power generation devices that use air turbines to create pressurized air. This uses the water surface, which moves up and down due to waves, and the air chamber to create pressurized air directly. In other words, if this is a head higher than the wave height, high pressure air cannot be created.
In other words, there was a problem in that air could not be sent to the deep ocean floor and lake bottom, making it impossible to purify them. In order to solve these problems, the present invention aims to purify water by using wave energy to create pressurized air at a relatively high pressure compared to the wave height and sending this into the water.

[Means and operations for solving the problem] In order to achieve the above object, wave energy is used to agitate the float of a wave pump, and this power is used to operate a piston in a cylinder installed underwater, By this operation, the working medium liquid flowing in and out of the cylinder is guided to the medium tank installed at the bottom of the water via a pipe, etc., and the liquid level in the water column pipe installed at the top of this medium tank can be greatly fluctuated. In other words, with this operation, air is sucked in from the air suction port provided at the top of the suction buoy, and by the action of the check valve, this air is sent into relatively deep water as pressurized air in a certain direction, thereby creating aeration. It can purify water by creating an action. [Embodiments] Examples of the present invention will be described below with reference to the drawings. Fig. 1 is a vertical sectional view showing the configuration of an aeration purification device using a wave pump, and what is shown on the left side of this figure is a vertical sectional view showing the configuration of the wave pump.
This figure shows float 1 of wave bomb A placed on the water surface.
The base block 2 is placed on the bottom of the water, and the saddle 3, cylinder 4, and piston 5 are installed on top of it as shown in the diagram.
Next, this piston, piston rod 6 and float 1
are connected with a chain 8 or the like. If the float 1 is agitated by waves in this state, the piston 5 will reciprocate within the cylinder 4. That is, the water in the cylinder 4 is sent out or sucked into the cylinder 4 via the pipe 7 by the action of the piston 5. Next, the drawing shown on the right side of this figure is a longitudinal sectional view showing the configuration of the pressurized air generator iB in the aeration purification device. In this figure, an air suction buoy 9 is first floated on the water surface, a medium tank 10 is placed at the bottom of the water, and an underwater pipe 1l with a fluctuating liquid level is installed above it.
Furthermore, as explained above, this submersible pipe serves as a pipe between the air suction pipe floating on the water surface and the medium tank provided at the bottom of the water. Next, a U-shaped pipe 12 is installed above the air suction port buoy 9, and one side of this pipe is equipped with the aforementioned buoy 9, and the other side is equipped with a check valve 13, a suction filter 14, etc. as shown in the figure. Assume that there is. Further, the pressurized air take-off pipe 15 is also provided as a U-shaped pipe above the buoy 9, and one side of this pipe connects to the buoy 9 via a check valve 16, and the other side connects this buoy vertically to the inside of the water column pipe 11. It is assumed that the water column penetrates in the direction of the water and is lowered to the bottom of the water, where it is drawn out from the water column pipe 11. That is, the water column pipe 11 is a double pipe system in which this pipe is the outer pipe and the pressurized air extraction pipe 15 is the inner pipe. This operation will be explained below. Now, suppose a wave comes and float 1 moves upward, lifting piston 5,
Assume that water in cylinder 4 is fed through pipe 7. That is, it is assumed that at the same time that this water is sent into the medium tank 10, the liquid level in the water column pipe rises significantly compared to the wave height. This is determined by the wave height and the shape of the float 1, as well as the pressure-receiving area of the piston 5 and the balance of the water column pipe l1, but the air in the water column pipe is pressurized and becomes pressurized air that passes through the check valve 16 and is applied. The compressed air is discharged from the bottom of the water to the outside from the pipe 15. This released air causes an aeration effect due to the difference in specific gravity between water and air and rises through the water. In other words, this action not only supplies oxygen to the oxygen-deficient water at the bottom of the water, but also causes the water at the bottom to flow, thereby purifying the water. Next, when the wave passes and the float 1 descends and the piston 5 is pulled down, the water in the tube 7 is drawn into the cylinder 4. In other words, the water in the W tank 10 is drawn into the cylinder 4 via the pipe 7. Therefore, in order to greatly lower the water level in the water column pipe 11, air is sucked into this pipe.
and is sucked into this tube from the outside via the filter 14. By repeating the above process, pressurized air is sent to the bottom of the water, and the contaminated water near the bottom is purified by aeration.
However, due to the structure of the device, the air suction loboy 9 is a floating type in this figure, but it can also be a fixed type with its feet raised from the bottom of the water. Therefore, it is conceivable to fix the water column pipe 11 and the pressurized air outlet pipe 15 with steel pipes or the like instead of using hoses or the like. In addition, the pressurized air take-off pipe 15 should be provided externally instead of having a double pipe structure inside the buoy 9 and the water column pipe 11.
If a double pipe system is used, the air suction lobe 9 will be floated by waves, causing friction between the outer pipe hose and the inner pipe hose. Therefore, the inside of the pipe is constantly cleaned and it is thought that seawater and lake water deposits are less likely to adhere to it. Next, it seems desirable that the water column pipe 1l and the pressurized air extraction pipe 15 should be suction hoses that can withstand vacuum. [Effects of the Invention] As explained above, the present invention makes it possible to create high-pressure pressurized air by utilizing wave energy and using a piston and cylinder as an intermediate medium mechanism. Therefore, water in relatively deep bodies of water can be purified. The present invention makes it possible to purify lake water with sludge on the bottom, as well as closed bays, fish farms, port facilities, etc., by relatively easily using natural energy without using power sources such as electricity.
