JP2002303243A - Wave power air compressor - Google Patents

Abstract

PROBLEM TO BE SOLVED: To send air into the depth under seawater more efficiently by a wave power air compressor as it was found that air hardly reached the depth because of the upward/downward movement of waves when observed a laver net in a laver farm on a laver fishing boat in the Ariake Sea in November 2000. SOLUTION: In order to increase the concentration of oxygen in seawater, a large number of wave force air compressors should be set at the request of laver producers because there are about 3.8 million supports of laver culture racks in the Ariake Sea during the laver season.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION An intake check valve and an exhaust check valve are provided on a pipe above a cylinder whose lower part is open. The intake / exhaust check valve is above the water surface, the open part is submerged, and a hose that sends air into the water is connected to the pipe on the exhaust valve side. For the cylinders, build and install a support for a laver culture shelf, a cultured raft or a dedicated support. The cylinder is designed to have a buoyancy so that the columns and raft do not float. The open area should be of the required length so that it is below the nori cultivation net, cultured sea radish, exhaust hose and air outlet. When the wave is concave, the air outlet is located above the water level inside the cylinder and in the water outside the cylinder. When a wave is generated on the water surface and the water surface acts downward inside the cylinder, the exhaust valve closes and the inside of the cylinder becomes negative pressure, and the intake valve opens to suck in the outside air. When the water level inside the cylinder acts downward, the water acts as a piston and becomes a suction process. When the water level inside the cylinder acts upwards, the suction valve closes and the air inside the cylinder is compressed. At this time, the inside of the cylinder becomes positive pressure, the exhaust valve opens, and the air goes through the exhaust valve bipe hose and is discharged into the water from the air exhaust port located above the water surface inside the cylinder, and the water acts as a piston, and the compression and exhaust process Becomes Due to the wave unevenness, suction, compression, and exhaust are repeated, and the air flow is discharged into the water from the intake valve, the cylinder, the exhaust hose, and finally to the outlet.

2. Description of the Related Art Heretofore, there has been no example in which the outside air is fed into water by the unevenness of waves to reduce the oxygen concentration in the water and contribute to the growth of aquaculture.

[0003]

All living organisms in the water sustain life with oxygen. When the underwater ecological form collapses and the oxygen concentration in the water decreases, the water decays and the underwater organisms die. By sending air into the ecologically distorted water, the oxygen concentration in the water increases, which purifies the water and prevents it from rotting, giving vitality to the creatures in the water. We want to regain the vitality of the aquaculture whose vitality has weakened due to the low oxygen concentration and to increase production.

[0004]

[Means for Solving the Problems] In the sea where it is difficult to obtain a power source, a large number of wave-powered air compressors are installed on the support of a nori culture shelf, a culture raft or a dedicated kui to move bubbles to the lower side of the culture. Send using Airstone.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The apparatus of the present invention was installed on a support of a nori culture shelf with a check valve for intake and exhaust above the water surface and an open part 2 m long underwater.

[0006]

EXAMPLE A performance test was conducted on March 24, 2001 at a seaweed farm in Fukuoka Prefecture, Ariake Sea.

[0007]

According to the present invention, the compressor is activated even by the wave that comes to the stern when the ship is running, and the air bubbles are released into the water.

Claims (1)

[Claims] 1. A negative pressure is generated by providing a pipe inside a cylinder, above a receiving cylinder, by using a cylinder having an open lower portion as a piston by using water flowing in and out of the open portion by an uneven action of waves. A check valve for intake that opens when positive pressure is closed and a check valve that closes when negative pressure is generated opens when positive pressure is applied. is there.
