[0002]

2. Description of the Related Art Conventionally, various shapes and structures of a fishing reef, such as a concrete block type or a synthetic resin or concrete assembly skeleton type, are known. It has achieved tremendous results in the propagation of marine animals and plants.

[0003]

However, conventional fishing reefs are intended to promote the habitat of fish or the adhesion and propagation of seaweed, and are expected to have a considerable effect in areas with seawater flow. I have. However, in sea areas where seawater tends to stagnate (for example, in bays where the tide is low), the environment is unsuitable for the propagation of fish and seaweed due to the influx of organic matter, lack of oxygen, lack of nutrient sources, etc. There was a problem that the effect of can not be mined. In the case of lack of oxygen, the propagation of aerobic microorganisms becomes impossible, the decomposition of organic substances by anaerobic microorganisms occurs, the generation of harmful substances (for example, hydrogen sulfide and other nitrogen compounds), and the propagation of fish and seaweed. Could be inhibited.

[0004]

However, the present invention provides a fishing reef with a pumping cylinder or a deep sea eutrophic seawater within a fishing reef.
Pumping to create convective convection and improve the environment within the reef
Thus, the above-mentioned conventional problems have been solved.

That is, the present invention relates to a three-dimensional fishing reef composed of rods.

[0010]

[Action] The present invention because it produces a forced circulation convection per the reef, it is possible to activate the organisms within the reef.
In addition, since not only oxygen but also nutrient sources are evenly distributed, fishing areas, marine pastures and seaweed breeding water areas are averaged over the entire area.

[0011] Since the pumping device fixed to the reef, installation and other work is almost identical to the installation of the reef. Due to the generation of currents, the distribution, distribution and spread of feed and nutrients is easy.

Embodiment 1 The present invention will be described with reference to FIGS.

The assembled fishing reef 2 is constructed by combining the synthetic resin rods 1, 1, and an intermittent air pumping device 3 is installed at the center of the assembled fishing reef 2. The assembling reef 2 assembles the large and small rods 1 and 1 manufactured in advance as needed to form a three-dimensional reef 2 having a predetermined shape, and if necessary, connects the respective reefs appropriately to provide a huge reef group (fishing reef water area). . The intermittent air pumping device 3 includes a pumping cylinder 4 and an air chamber 5 fitted and installed at a lower portion thereof. The air chamber 5 has an inner cylinder 6 loosely fitted to the pumping cylinder 4 with a predetermined gap therebetween. It comprises an outer cylinder 7 which is loosely fitted to the outside, and a partition cylinder 8 provided at an intermediate portion between the inner cylinder 6 and the outer cylinder 7. Vent holes 9 and 10 are provided at the lower end of the inner cylinder 6 and the upper end of the partition cylinder 8, and a vent 11 with the air chamber 5 is formed in the lower part of the pumping cylinder 4. In FIGS. 1 and 2, reference numeral 12 denotes a surface plate for fixing the pumping device, reference numeral 13 denotes a fixed leg, reference numeral 14 denotes a fixed plate of a fishing reef, and reference numeral 15 denotes a guide rod of the pumping cylinder 4.

As shown in FIG. 5, for example, the practice reef is installed on a relatively shallow seabed 32 (continental shelf), and is used by a compressor (not shown) installed on land or on the sea (on board). When the pressurized air is supplied to the air chamber 5 via the arrow 16 as shown by an arrow 17, the water level in the air chamber 5 falls as shown by an arrow 18 in FIG. Thus the water level is 1
When the air pressure reaches 0, the air in the air chamber 5 becomes arrows 19, 20,
As shown in FIG. 21, it passes through each of the ventilation holes 9, 10, 11 and enters the pumping cylinder 4, becomes an air bullet 22, and shows an arrow 23 for buoyancy.
Rise like. When the air bullets 22 rise, the water in the pumping cylinder 4 also rises with this, so that water is absorbed from the lower part of the pumping cylinder 4 as indicated by an arrow 24. Therefore, the recirculation of arrows 25, 26, 27, 28, and 24 is generated around the pumping cylinder 4. Therefore, the seawater with a large amount of dissolved oxygen near the water surface 31 mixes with the rising water and descends, so that the dissolved oxygen amount averaged over a relatively short time (1 to 7 days). This means that the water temperature becomes constant, the nutrient sources become uniform, the breeding of seaweeds 35, 35, and the like becomes prosperous. Is established. The propagation of microorganisms
It will provide harmless organic substance harmlessness and fish breeding.

Embodiment 2 In the embodiment of FIG. 6, the upper end of a suction pipe 29 is directly connected to the lower end of a water pumping cylinder 4, and the lower end of the suction pipe 29 is laid in a deep sea eutrophic layer 30. .

In this case, if pressurized air is supplied from the hose 16 as indicated by an arrow 17, as in the first embodiment, air bullets intermittently rise in the pumping cylinder 4, and the Water bottle 4
The seawater in the suction pipe 29 also flows in the direction of the arrow 33, and is discharged from the upper end of the water pumping cylinder 4 in the direction of the arrows 34, 34. On the other hand, the seawater in each reef 2, 2 since the upper and lower reflux as described above, eutrophic seawater eventually deep sea is diffused into the reef and the reef zone, effectively as a nutrient source for fish and seaweed Will be used.

The installation position, diameter, length, etc., of the pumping cylinder for sucking up nutrients in the above embodiment are determined as appropriate in consideration of the specifications of the fishing reef and the fishing reef area. In the figure, 31 is the sea surface, 32
Is the sea floor.

[0018]

According to the present invention, since a forced circulation environment is provided in each fishing reef , there is an effect of promoting the reproduction of fish and seaweed and stabilizing an ecosystem. In addition, since nutrient sources in the deep sea are supplied to the inside and outside of the reef and diffused, there is an effect that a large amount of nutrients or feed can be provided at low cost.

Next , since the intermittent air pumping device is combined in the reef, seawater inside and outside the reef is forcibly circulated and the environment inside the reef is reduced.
If the system is operated continuously, it will be possible to generate reflux near the reef, and the entire sea area where the reef is located
The there is a Ru effect that can improve the environment.
