Description

Artificial fish reef with box body structure

Technical Field

The utility model belongs to artificial fish reef field, concretely relates to box structure's artificial fish reef.

Background

The artificial fish reef is a structure artificially arranged in the sea, and aims to improve the ecological environment of the sea area, build a good environment for the inhabitation of marine organisms, provide places for the propagation, growth, bait making and enemy sheltering of fishes and the like, and achieve the purposes of protecting, proliferating and improving the harvest yield. At present, the construction of artificial fish reefs is widely carried out at home and abroad to repair the habitats and fisheries of offshore marine organisms, and a better effect is achieved.

The fish reef is a seabed reef or other protrusion suitable for inhabitation, growth and propagation of fish clusters. The peripheral sea current brings organic matters on the seabed and nutrient salts near the seabed to the upper layer of the sea water, promotes mass propagation and growth of various bait organisms, provides a good inhabitation environment and a cable bait propagation place for fishes and the like, and leads the fishes to gather to form a fishing ground. The method is characterized in that a proper sea area is usually selected, stones, trees, waste vehicles and ships, waste tires, reinforced cement prefabricated blocks and the like are put in the sea area to form the artificial reef, so that the bottom layer and the middle and upper layer fish resources with inhabitation and migration properties can be trapped and increased, and a relatively stable artificial fish reef fishing ground is formed.

The artificial fish reef has larger mass which is usually more than 50 tons, and can promote the upwelling when thrown into the sea, so as to bring the low-temperature and rich-nutrition seawater on the sea bottom. However, the conventional artificial fish reef is a cubic box body, and a plurality of through holes are formed in the box body. The surface area of the top part is small, and more nutrient substances cannot be attached.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an artificial fish reef of box structure to solve the less problem of prior art top area.

In order to achieve the purpose, the basic scheme of the utility model provides an artificial fish reef with a box body structure, which comprises a box body, wherein the top of the box body is hemispherical, the bottom of the box body is flat, the top of the box body is provided with a first through hole, the bottom of the box body is provided with a second through hole, and the first through hole and the second through hole are vertically aligned; the side surface of the box body is provided with a plurality of third through holes, the inner wall of the box body is provided with a plurality of transplanting holes, and seaweed is transplanted in the transplanting holes.

The first optimization scheme is as follows: a spoiler is arranged below the seaweed and fixed inside the box body.

And the second optimization scheme is as follows: the top of the box body is provided with a plurality of gathering holes, and the gathering holes are uniformly distributed on the top of the box body.

And the optimization scheme is three: the opening of the transplanting hole is fixedly connected with a sealing plate for sealing the transplanting hole, and an exposing hole is formed in the sealing plate.

And the optimization scheme is four: the bottom of the box body is fixedly connected with a vertical fixing rod, dispersing blades are connected to the fixing rod in a rotating mode, the dispersing blades are arranged in an inclined mode, and the fixing rod is vertically arranged in the center of the top of the box body.

The beneficial effect of this scheme lies in: 1. the design of this scheme hemisphere has increased the surface area at box top, can be depended on by more nutrient substance, attracts more fishes, promotes and lures the collection effect.

2. First through-hole and the vertical alignment of second through-hole in this scheme make the box sink in the sea, and rivers pass first through-hole and second through-hole smoothly, have reduced the resistance that the box received, have promoted the speed that the box descends. The product of the flow velocity of water flow around the box body and the thickness or the width of the box body can more easily reach 100cm/s, namely, a better back vortex area serving as a fish shelter site, a bait station and a breeding farm can be more easily formed near the box body.

3. The algae that sets up in this scheme on the one hand can gush when the box whereabouts and upwelling form the back and adsorb more nutrient substance, and on the other hand reduces the damage of roe as the adnexed ovum base of fish, promotes fish reproduction rate.

Drawings

Fig. 1 is a schematic structural view of an artificial fish reef with a box body structure according to an embodiment of the present invention;

FIG. 2 is a cross-sectional view of the present solution;

fig. 3 is a schematic structural diagram of the present scheme in embodiment 2.

Detailed Description

The present invention will be described in further detail with reference to the following embodiments:

reference numerals in the drawings of the specification include: the device comprises a third through hole 1, a first through hole 2, a box top 3, a second through hole 4, a gathering hole 5, a box bottom 6, seaweed 7, a transplanting hole 8, a spoiler 9, a fixing rod 10 and dispersing blades 11.

Example 1: the artificial fish reef with the box body structure comprises a box body, wherein the top part 3 of the box body is hemispherical, the bottom part 6 of the box body is flat, and the top part 3 and the bottom part of the box body are riveted into a whole. 3 integrated into one piece in box top has first through-

hole

2, and 6 integrated into one piece in bottom half has second through-hole 4, and first through-hole 2 and the vertical alignment of second through-hole 4 make rivers can be smooth pass the box, reduce the sunken resistance of box. A plurality of third through holes 1 are integrally formed in the side face of the box body, and the third through holes 1 are located on two sides of the box body which is not fixed.

A plurality of transplanting holes 8 are integrally formed in the inner wall of the box body, and seaweed 7 is transplanted in the transplanting holes 8. Fixedly connected with the shrouding that seals transplant hole 8 is transplanted to 8 opening parts screw thread, and integrated into one piece has the exposure hole on the shrouding for expose marine alga 7. The spoiler 9 is arranged below the seaweed 7, and the spoiler 9 is fixed inside the box body. The box top 3 integrated into one piece has a plurality of gathering holes 5, and gathering holes 5 evenly distributed are at box top 3 for deposit more nutrient substance at box top 3.

Example 2: on the basis of the embodiment 1, as shown in fig. 3, the bottom 6 of the box body is fixedly connected with a vertical fixing rod 10, the fixing rod 10 is rotatably connected with a rotating sleeve, the rotating sleeve is fixedly connected with a dispersing blade 11, the dispersing blade 11 is obliquely arranged, and the fixing rod 10 is vertically arranged on the center of the top 3 of the box body. When the box body sinks, the water flow pushes the inclined dispersing blades 11 to rotate, the water flow is dispersed around in the box body, so that nutrient substances in the water flow are fully contacted with algae and attached to the algae 7.

It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention.
