Description

Large integrated floating cage

technical field

The invention relates to a deep water net cage, in particular to a large integrated floating net cage.

Background technique

The breeding cage is composed of four parts: cage frame system, net clothing system, mooring system and supporting facilities system. Wherein the mooring system is the foundation of the cage in the water, once the mooring fixing system has problems in windy and wave weather, it will cause the whole cage to be damaged due to uneven stress. At present, there are three common cage mooring forms at home and abroad: one is the traditional multi-point mooring; the other is the surface grid mooring; the third is the underwater grid mooring. The traditional multi-point mooring system is simple in form. At present, this method is mostly used in coastal floating deep-water cages in my country. In multi-point mooring, there are three types of anchors according to different sea areas. One is pile anchors, which are relatively cheap and suitable for shallow water and sandy bottom sea areas; the other is cement anchors, which are moderately priced and suitable for sandy or Sea areas with sandy bottom; the third is iron anchors, which are more expensive and suitable for sea areas with more complicated seabeds.

Contents of the invention

The purpose of the present invention is to provide a large-scale integrated floating net cage with firm structure, convenient net replacement, stable space state, good wind and wave resistance effect and convenient fishing from the prior art.

The technical solution adopted by the present invention to solve the above-mentioned technical problems is: a large-scale integrated floating net cage, including an inflatable floating frame, wherein: a net is hung on the lower side of the floating frame; a support tube is provided at the bottom of the net; sinkers are evenly distributed; the support pipe is connected with a bottom frame anchor rope; the floating frame is connected with a top anchor rope; The double anchoring system has the top anchoring rope and the bottom frame anchoring rope in pairs, so that the position of the support tube can be relatively stable and located directly below the floating frame, so that the breeding capacity inside the net is relatively stable, and can Reduce the tension of the net clothing on the side, especially the traction rope, to prevent the entire cage from being damaged due to strong waves.

In order to optimize the above-mentioned technical scheme, the measures taken also include: a net is hung on the lower side of the floating frame; a support pipe is provided at the bottom of the net; sinkers are evenly distributed on the support pipe; anchor ropes are connected to the bottom frame of the support pipe; The frame is connected with a top anchor rope; the bottom of the top anchor rope and its paired bottom frame anchor rope are jointly connected on an anchor body. The double anchoring system has the top anchoring rope and the bottom frame anchoring rope in pairs, so that the position of the support tube can be relatively stable and located directly below the floating frame, so that the breeding capacity inside the net is relatively stable, and can Reduce the tension of the net clothing on the side, especially the traction rope, to prevent the entire cage from being damaged due to strong waves. The floating frame has an external frame body surrounded by two semicircular frames and two side frames; and, the two side ends of the side frames are connected through the main support frame; the middle part of the side frame is connected through the auxiliary support frame; The middle part of the secondary support frame and the main support frame is connected via a longitudinal connecting frame. The outer frame surrounded by the two semicircular frames and the two side frames has a side with a small cross-sectional area, so it can be directly facing the direction of tidal water flow, so as to achieve the effect of wind and flow resistance. The main support bracket is used to stabilize the semi-circular frame. The auxiliary support frame and the longitudinal connection frame are used to strengthen the frame surrounded by the side frame and the main support frame. When catching fish, first loosen the knots of the nets at both ends, slide along the main frame to the center, and then start catching fish through the fish suction pump. Uniformly distributed traction ropes are also arranged between the floating frame and the supporting pipe; the supporting pipe is located inside the projection surface of the floating frame. The traction rope distributes the traction force on the support pipe to the floating frame, and since the traction rope forms an inverted truncated cone shape, the traction force of the whole net clothing when the floating frame rises and falls is reduced. When changing the net, loosen the knot at one end, move the old net to the center, replace it with a new net, connect the old and new net, loosen the other end of the old net, move the fish to the new net, and take out the old net. Net, complete the net clothing replacement. A floating ball is connected near the middle of the top anchor rope; a floating ball is connected near the middle of the bottom frame anchor rope. The floating ball can pull the traction direction of the top anchor rope and the bottom frame anchor rope to the possible horizontal direction so far, so as to optimize the traction effect on the horizontal swing of the floating frame and the support pipe. The length of the floating frame is 50 to 90 meters. The preferred length is 70 meters, which is close to the wavelength of general waves. Therefore, the wave force borne by each part of the cage within a wavelength can cancel each other out, and because of the large size of the cage, vertical fluctuations will not cause greater damage to the cage. The wind and wave performance is better. Adopting the traditional circular structure will cause disadvantages such as too large span, unstable structure, and unmanageable. In terms of flow resistance, because the two ends are designed as inclined structures, it can play a role in diverting flow and improve the flow resistance performance.

Because the present invention adopts the net clothes hanging on the lower side of the floating frame; the bottom of the net clothes is provided with a support pipe; the support pipe is evenly connected with sinkers; ; The bottom of the top anchor rope and its paired bottom frame anchor rope are jointly connected on an anchor body. The double anchoring system has the top anchoring rope and the bottom frame anchoring rope in pairs, so that the position of the support tube can be relatively stable and located directly below the floating frame, so that the breeding capacity inside the net is relatively stable, and can Reduce the tension of the net clothing on the side, especially the traction rope, to prevent the entire cage from being damaged due to strong waves. Therefore, the present invention has the advantages of solid structure, convenient net change, stable space state, good anti-wind and wave effect, and convenient fishing.
