The present invention relates to an apparatus for improving the seabed environment, and relates to an apparatus capable of improving the seabed environment by inhaling substances from the seabed and purifying and discharging materials other than fish and shellfish.

As for the seabed environment improving device, a marine shellfish harvesting device serving as a seabed tidal flat improvement is disclosed in Korean Patent Publication No. 468487, and a seabed environment improving device serving as a fish and shellfish harvesting function in Korean Utility Model Publication No. 398151.

The accompanying Figure 1 shows a vessel equipped with a conventional subsea environment improvement apparatus approaching the oyster farm.

As shown in Figure 1, the conventional apparatus for improving the seabed environment, the compressor 11 and the mixing cylinder 22 is installed in the vessel and the discharge hose (3), suction hose (2), discharge hose (8) connected to the seabed And a towing rope (1a) to tow them, and an excavator body (1), a duct (2b), a drilling blade (5), a discharge pipe (9) and a harrow plate (10) located on the seabed.

When the excavator body (1) connected to the hull by the towing rope (1a) is dropped on the seabed to reach the mud flat, the hull is advanced. When the excavator body 1 is towed at 2 to 6 knots per hour, the excavator body 1 is inclined at about 45 °, and the excavator blade 5 fastened to the excavator body 1 in the horizontal direction is also inclined.

Subsea tidal flats and fish and shellfish dug by excavation blade (5) are supported by high pressure air blown out from the blowing hose (3) connected to the compressor (11) through the suction hose (2) through the duct (2b) without water pressure After being sucked in, it is placed on the filtration net installed in the hull. Of those that do not pass through the filter net, fish and shellfish are collected separately by hand, and objects beneficial for tidal flats are ground with tidal improvers (ocher, bovine, quicklime, elvan, shells, etc.), along with those that have passed through the filter net. The mixing vessel 22 is mixed.

The mixed in the mixing vessel 22 is discharged to the seabed tidal flat through the discharge hose (8) and the discharge pipe (9), the harrow plate (10) mounted to the rear of the discharge pipe (9) to embed the discharge into the seabed tidal flat Do the work.

Vessels equipped with such a seabed improvement system cannot enter aquaculture farms. Furthermore, since the excavator body 1 is towed by the ship, it cannot enter near the seabed corresponding to the position of the farm. If a ship equipped with a subsea environment improvement system to improve the subsea environment of the farm is forcibly entered the farm, the result is that the farm is destroyed.

The farm is a place that requires environmental improvement than anywhere else for healthy fish, seaweed, crustaceans, etc., but it is difficult to improve the environment under the sea in the conventional seabed environment improvement device.

In addition, the conventional subsea environment improvement device has a problem that can not be used smoothly in the seabed with a lot of stones or rocks.

The present invention is to solve the problems as described above, it is possible to improve the subsea environment of the farm without harming the farm, and to provide a subsea environment improvement device that can contribute to high quality aquatic farming.

It is also an object of the present invention to provide a subsea environment improvement apparatus that can be used in any subsea environment including a rocky or rocky area without being affected by the flow of seawater.

As shown in FIG. 2, the apparatus for improving the seabed environment according to the present embodiment includes a high pressure air supplier 11; A purifier 30 having an inlet 31 and an outlet 32; A suction hose (3) having an upper end connected to the high pressure air supply (11) and ejecting the high pressure air from the lower end to the seabed, and an upper end connected to the inlet port (31) and having a lower end near the lower end of the ejection hose (3). (2), the hose portion 40 including a discharge hose (8) connected to the discharge port (32). In FIG. 2, an illustration of a weight installed in the middle of the hose part 40 is omitted, which will be described later with reference to FIG. 6.

The high pressure air supply 11 includes a compressor, an air lift pump, or the like. A compressor is a mechanical device that compresses gas and raises pressure. The high pressure air supplier 11 is installed to supply high pressure air to the jet hose 3, and may be connected to the upper end of the jet hose 3 through a distribution tube 14 for the jet hose having a control valve 16. .

A duct 2b may be connected to the lower end of the suction hose 2. It is dug up by the high pressure air jetted from the lower end of the jet hose 3 which is located at the bottom of the seabed, and the floating seabed tidal flats and fish and shellfish are sucked into the suction hose 2 through the duct 2b without water pressure. By forming a plurality of holes in the upper plate of the duct 2b, it is possible to minimize buoyancy and air pressure received by the duct 2b, and to smoothly and stably maintain the lift of the buoyant through the suction hose 2.

The buoyant sucked through the suction hose 2 is introduced into the purification unit 30 through the inlet 31 connected to the upper end of the suction hose 2.

The purifying unit 30 may include a filtering net 18 for filtering the buoyant coming from the inlet 31 and a mixing chamber 22 in which beneficial ones for improving tidal flat are mixed. Fish and shellfish that have not passed through the filter net 18 can be collected separately by hand, and the remainder can be introduced into the grinders 19 and 19a together with a tidal improver (ocher, bovine and quicklime, ganban rock, shells, etc.). .

The filter net 18 can be formed in a double structure up and down, so that bulky ones such as fish and shellfish can be caught on the upper filter net 18 without manual labor. The grinders 19 and 19a may also be formed in a double structure so that coarse grinding is performed in the first grinder 19 and fine grinding is performed in the second grinder 19a.

The pulverized product which has passed through the grinders 19 and 19a flows into the mixing chamber 22 via the conveyance path 20 connected with the inlet of the mixing chamber 22. Those that have passed through the filter net 18 also flow into the mixing chamber 22 via the inlet chamber 17 and the drainage channel 17a.

The mixing chamber 22 may be connected to the high pressure air supply 11 by a mixing distribution pipe 12 having a control valve 16. The high pressure air ejected from the mixing distribution pipe 12 by the high pressure air supply 11 helps to mix the pulverized matter passed through the grinders 19 and 19a and those passed through the inlet chamber 17 well.
