Description

Reinforced concrete fish reef

Technical Field

The utility model relates to an aquatic product farming equipment.

Background

In aquatic product cultivation, fish cultivation is very important one, and in order to improve the breed income, people generally adopt artificial fish reef form to breed, artificial fish reef is just artificial sets up a plurality of fixed object in the sea, and the fish that supplies to breed perchs and lives. The artificial fish reef has a plurality of forms, and is generally made of cement, has a plurality of open holes and is similar to cement members of cement frames of buildings. It has the following disadvantages: although the cement member has many holes, each surface is relatively smooth, the fish eggs and fish fry attached to the surface are washed away by the seawater which flows continuously under the action of wind waves, only the fish eggs and fish fry hidden at the corners can survive, and the feed and marine plankton for eating the fish eggs and fish fry are difficult to preserve. Because the existing artificial fish reef is not suitable for fish survival, the fish culture benefit is very low.

Disclosure of Invention

An object of the utility model is to provide a be fit for stable growth of roe and fry and breed the reinforced concrete fish reef that the benefit is high.

The utility model mainly comprises a base and a fish cage. The base is a cement member which is made of cement and has a certain height, the height of the base is determined according to the seabed condition of the working position of the base, and if the seabed is a stone, the height of the base is consistent with the structural strength of the member; if the seabed is sand, the height of the base is increased properly to prevent the seabed from being completely buried by the sand. The upper surface and the lower surface of the base are both planes, which can be a complete plane or a combination of a plurality of planes; it can be solid or hollow, and is preferably frame-shaped to adapt to rugged seabed. The shape of the base can be designed into various shapes, such as rectangle, circle, polygon or other shapes designed according to the use site. Be equipped with a plurality of pre-buried metal connecting pieces on the base, these pre-buried metal connecting pieces correspond and interconnect with the metal connecting piece on the fish cage metal framework lower shed respectively, and it can be if the welding links firmly, also can adopt connecting piece swing joint to fix metal frame and constitute whole fish reef frame on the base. The fish cage mainly includes: metal frame, kelp seedling rope and screen cloth. The metal frame is a lower opening groove-shaped frame consisting of a plurality of connected metal section bar grids, and the size of the lower opening is less than or equal to the external size of the base. The metal frame can be made into various shapes, such as a cube shape, a cylinder shape, a polygon prism shape or a special shape designed according to the landform. However, the side surface of the metal frame is provided with at least one grid, namely an access hole, in which the horizontal metal frame is not arranged in the middle for the diver to enter and exit. Preferably, the metal frame is provided with a reinforcing rib. On the metal frame tank bottom face is the metal section bar of fish reef frame top surface, be fixed with a plurality of kelp seedling ropes discontinuously, the molding of this kelp seedling rope designs as required, and length is less than the metal frame height, and kelp seedling rope lower extreme is the free end. Preferably, the top of the metal frame is covered with a polyethylene mesh having a mesh size smaller than that of the fishing gear to prevent the fishing gear from entering. In addition, the outer side surface of the metal frame is covered with side mesh cloth which covers the partial outer side surface of the metal frame, so that the normal flow of seawater is not influenced, and a part of ocean current and wind waves can be blocked, so that the living environment of marine products in the metal frame is more stable.

The utility model discloses assemble earlier on the land, be about to a plurality of kelp seedling ropes and be interrupted the system on the metal section bar of metal crate bottom, cover the screen cloth respectively again on metal crate top and side and fixed with the net rope, then arrange the metal crate opening in on the base, make metal crate's metal connecting piece and the pre-buried metal connecting piece of base link firmly. And hoisting the assembled fish reef to a ship and putting the fish reef at a specified position positioned by a GPS satellite. The bottom surface of the base is placed on the seabed directly or on other fixed objects.

Compared with the prior art, the utility model have following advantage: a plurality of sea area seedling ropes are like the protection forest, in addition, the effect of screen cloth, can slow down the speed that flows through fish reef water, a stable living environment of perching and foraging has been built for the fish of breeding, more importantly can adhere to the ovum of fish on it, and still adhere to many marine plankton of marine alga, supply them to eat, make it become natural incubator, propagate the growth, can self-propagating autotrophy carries out virtuous circle, form a natural growth chain, can reduce the breed cost like this, the output of fish is high again simultaneously, high quality.

In the figure: 1. the device comprises a base, 2 parts of a pre-buried metal connecting piece, 3 parts of a fish cage, 4 parts of a metal frame, 5 parts of an access hole, 6 parts of a cross-shaped reinforcing rib, 7 parts of a corner reinforcing rib, 8 parts of a kelp seedling rope, 9 parts of a kelp seedling rope ear, 10 parts of a net cloth, 11 parts of a side net cloth.

Detailed Description

In the schematic three-dimensional schematic diagram of the reinforced concrete fish reef shown in fig. 1, a base 1 is a frame-shaped cement member which is made of cement and has a certain height, the upper surface and the lower surface of the base are both planes, the base is rectangular, a plurality of pre-embedded metal connecting pieces 2 are discontinuously arranged on the base, as shown in fig. 2, the pre-embedded metal connecting pieces are respectively welded with metal connecting pieces on the lower opening of a fish cage 3, namely the metal frame, and the metal frame is fixed on the base to form the whole fish reef frame. The metal frame 4, as shown in fig. 3, is a 4m × 3m × 2.5m cubic lower opening groove-shaped frame composed of a plurality of connected 18mm screw steel grids, and the size of the lower opening is smaller than the external size of the base. Two opposite side surfaces of the metal frame are respectively provided with a grid, namely an access hole 5, in which a horizontal metal frame is not arranged in the middle for a diver to enter and exit.
