Technical Field

The utility model relates to an aquaculture, artifical fish shelter, marine ranch technical field specifically are a porous many gaps of pentagon three-layer iron frame type collection fish shelter.

Background

In fishery production and management, in some cases, fish schools need to be induced and concentrated together through artificial fish reefs or artificial devices, for example, in a range of a marine ranch water area with a certain limited space range, in order to classify and manage fish schools into young fishes, juvenile fishes, sub-adult fishes, adult fishes and parent fishes, a nursery, a breeding farm, a fishing farm and a breeding farm need to be respectively set up. In a fishing farm, artificial members or artificial reefs with good fish gathering effect are required to be set aiming at sub-adult fish and adult fish groups.

SUMMERY OF THE UTILITY MODEL

Problem to prior art existence, the utility model provides a porous many gaps of pentagon three-layer iron frame type collection fish reef to solve above-mentioned at least one technical problem.

The technical scheme of the utility model is that: the utility model provides a porous many gaps of pentagon three-layer iron frame type fish collection reef, includes a fish reef main part, its characterized in that, the fish reef main part includes three dead levers, install three-layer frame from last to lower in proper order on the dead lever, every layer of frame is crisscross arranges, the frame is the pentagon, the apex angle department of frame all is equipped with annular metalwork, the dead lever passes annular metalwork, just the dead lever with annular metalwork swing joint, three dead levers pass three annular metalwork in the annular metalwork of five apex angles of every layer of frame respectively;

every side of frame is fixed with an extension frame respectively, it is the iron-made frame of right angled triangle structure to extend the frame, it includes a long right angle limit, short right angle limit and an hypotenuse to extend the frame, long right angle limit with the side laminating of frame, long right angle limit with short right angle edge covers there is the separate layer, just the water conservancy diversion hole has been seted up to the central authorities of separate layer.

The utility model discloses an induced purpose of concentrating shoal of fish, through frame rack construction, the structure is complicated, and the space is numerous, be fit for a large amount of shoals and perch wherein, extend the frame and can carry out classification management with inferior adult fish with cutting apart the layer, provide the biggest possibility reef cubical space in limited water, because the space is three-dimensional, hold the greater amount shoal of fish, simultaneously with reef body control at the three-layer, can avoid the fish reef to receive stormy waves effect and take place to topple over and overturn, find the balance in structural stability and attracting fish gathering fish effect.

Preferably, the three fixing rods are respectively provided with a limiting block, and the limiting blocks are positioned between the two adjacent layers of frames. Thereby certain gaps can be generated, the friction between every two layers of frames is prevented, and the circulation of seawater can be facilitated.

Preferably, the limiting block is an elastic rubber block with a notch, a fixing channel is arranged in the center of the elastic rubber block, and the inner diameter of the fixing channel is consistent with the outer diameter of the fixing rod.

The utility model discloses an optimized the structure of stopper, can be convenient for take the installation, make things convenient for putting up of frame.

Further preferably, the partition layer comprises a metal mesh, and the metal mesh is covered with concrete. Thereby generating rough surface, facilitating the propagation of algae and providing nutrient substances for fish.

Preferably, the long right-angle edge is provided with two diversion holes, and the short right-angle edge is provided with one diversion hole. Therefore, the sub-adult fish can be introduced into the center of the frame, so that the classification management is convenient, and external nutrient substances are conveniently brought to the center of the frame in a flowing mode.

Further preferably, the frame is in a regular pentagon shape, and the three fixing rods are arranged in a triangular structure. The stabilizing effect is good under this structure, is difficult to be scraped down by the wave.
