Description

A High Stability Artificial Fish Reef

technical field

The invention relates to the technical field of fish reefs, in particular to an artificial fish reef with high stability.

Background technique

In recent years, although my country's fishery has developed by leaps and bounds, the traditional marine fishery is still in the extensive stage. Due to overfishing and environmental pollution, especially the high-intensity operation of lethal fishing gear such as bottom trawling, the ecological environment of my country's offshore fishery has deteriorated. Resource decay. In view of the above problems, it is imperative to take measures to improve the marine environment and resources. Among them, putting artificial reefs in the offshore to improve the marine ecological environment has achieved good results. Putting artificial reefs is very important for restoring and protecting offshore fishery resources, improving The coastal ecological environment has played a very important role.

Although there are many kinds of existing artificial reefs, they are mainly aimed at providing places for fishes to breed, grow, bait, and shelter enemies. The emergence of thermoclines and haloclines slows down the vertical exchange of water bodies and forms an anoxic layer on the seabed, which easily leads to the death of aquatic organisms such as sea cucumbers. At the same time, some artificial reefs require high stability when they are placed, while artificial The use stability of fish reefs on the seabed is low, and the use function of artificial fish reefs on the seabed cannot be guaranteed. Therefore, how to improve the upwelling effect of the artificial reef and improve the stability of the artificial reef is a problem that we should further solve.

Contents of the invention

The purpose of the present invention is to provide a high stability artificial fish reef, which can provide necessary and safe habitats for the gathering, baiting, breeding, growth and avoiding enemies of aquatic organisms such as fish, and it can also generate upwelling, which can Change the distribution of the flow field in the sea area, drive the exchange of nutrient salts from the bottom layer with the upper water body, provide nutrients for the reproduction and growth of plankton in the upper water body, create a good habitat for marine organisms, enhance the reproduction and breeding capacity of plankton, and form a pole. An excellent bait field, attracting the gathering and retention of migratory fish, and achieving a better fish gathering effect. At the same time, it can also reduce the difficulty of putting artificial fish reefs in, ensure the use of artificial fish reefs on the seabed, and improve the quality of artificial fish reefs. Reef stability for the purpose of protecting, adding value to fishery resources and increasing catches.

The purpose of the present invention is achieved through the following technical solutions: it is composed of a fish reef body, ribs and support columns, the fish reef body is a regular triangular pyramid structure, and each cone top of the fish reef body is inlaid with a length For equal support columns, the included angle between any two support columns is 120°, ribs are arranged between the support columns, and the ribs are connected to the edges of the fish reef body.

Salient feature of the present invention is:

The fish reef body of a high-stability artificial fish reef is a regular triangular pyramid structure, which can effectively use the ocean current. When the ocean current flows through the fish reef body, the cone structure can effectively reduce the loss of water flow power, which is conducive to increasing the height of the upwelling , so that the nutrients deposited on the seabed rise, drive the bottom nutrient salt to exchange with the upper water body, provide nutrients for the reproduction and growth of plankton in the upper water body, create a good habitat for marine organisms, and achieve a better fish gathering effect. A large-scale back vortex is formed on the side and back of the reef body, providing various flow field environments for different fish.

A high-stability artificial reef is provided with ribs between the supporting columns, which can reduce the horizontal flow of water to both sides of the reef, further reducing the loss of water flow force on the outer side of the reef body, thereby improving the rise The flow and height of the current cause the nutrients deposited on the sea floor to rise.

A kind of high-stability artificial fish reef. Each conical top of the fish reef body is inlaid with support columns of equal length. When any three support columns are used as supports, the structure and functions of the artificial fish reef on the seabed are the same, and can Reduce the difficulty of putting artificial reefs in, while ensuring the use function of artificial reefs on the seabed, and improving the stability of artificial reefs.

Detailed ways

Below by embodiment, technical solution of the present invention is described further in conjunction with accompanying drawing:

Referring to Fig. 1, a high-stability artificial fish reef provided by the embodiment of the present invention is composed of a fish reef body 1, ribs 2 and support columns 3, and the fish reef body 1 is a regular triangular pyramid structure, so Each cone top of the fish reef body 1 is inlaid with support columns 3 of equal length, the angle between any two support columns 3 is 120°, and ribs are arranged between the support columns 3 2. The ribs 2 are connected to the edges of the fish reef body 1 .

Referring to Figure 1, when the artificial reef is placed on the seabed, when any three supporting columns are used as supports, the structure and functions of the artificial reef on the seabed are the same, which reduces the difficulty of artificial reef when it is placed, and at the same time ensures that the artificial fish The use function of the reef on the seabed improves the stability of the artificial reef.

See Figure 1 and Figure 2. When the seabed water flows through the side of the fish reef body, an ascending water flow will be formed. The cone structure can effectively reduce the loss of water flow power, which is conducive to increasing the height of the upwelling. The function of upward diversion reduces the horizontal flow of water to both sides of the reef body, which can further reduce the loss of water flow power on the side of the reef body, thereby further increasing the flow and height of the upwelling, so that the nutrients deposited on the seabed rise, Drive the exchange of bottom nutrient salts with the upper water body, create a good habitat for marine organisms, which is conducive to adding value and optimizing fishery resources, saving rare and endangered species and protecting biodiversity. The vortex provides various flow field environments for different fish.

See Figure 3. The water flow inside the ribs at the bottom of the artificial reef is relatively slow, which provides a necessary and safe habitat for juvenile fish to gather, grow and avoid enemies. At the same time, the inside of the ribs is conducive to the attachment of fish eggs, which is beneficial to fish aquatic organisms to achieve the purpose of protecting, adding value to fishery resources and increasing catches.
