Problems solved by technology

The main risk is that there are often typhoons in the coastal areas of our country, resulting in the destruction of the cages.
[0003] Most of the existing cages are floating cages with simple structures and poor wind and wave resistance
In order to prevent the net cage from being damaged by the impact of wind and waves, a lift-type anti-wind and wave deep-water net cage has emerged. The net of the net cage can be submerged in the water, but its main frame is still floating on the water surface. When a typhoon strikes, the main frame is easily washed away; Although other liftable net cages can realize the lifting function, the operation is cumbersome, so it is necessary to design a net cage that can prevent typhoon attacks and is easy to operate

Embodiment 1

[0030] Such as figure 1 , figure 2 , image 3 As shown, the deep-water net cage that can be raised and lowered against wind and waves includes a sac net, a pontoon 2, a frame 1 and an anchoring device 6, and can be used for aquaculture in the sac net. The sac net has an openable and closable net cover, and the sinking frame When the net cover is closed to prevent fish from escaping, the buoy 2 is a hollow plastic bucket, and the net and the buoy 2 are fixed on the frame 1. The frame 1 floats by the buoyancy of the buoy 2, and the frame 1 is connected to the mooring device 6 at the bottom of the water. It can be an anchor hook or a cement pile. After the frame 1 is connected to the anchoring device 6, the frame can be prevented from drifting away with the waves.

[0031] The cage also includes a lifting device 4 and a lifting rope 5. The lifting device 4 and the cage frame 1 are connected by a rope 3. One end of the lifting rope 5 is fixed on the lifting device, the other end is a...

Embodiment 2

[0041] Such as Figure 4 , Figure 5 As shown, the lifting and anti-wind and wave deep-water net cage, the locking member of the locking mechanism is cylindrical, and the other structure is the same as the first embodiment. Both ends of the cylindrical clamping member 410 can directly extend out of the chute 43, and the control rope 7 is connected to the card At both ends of the member 410, since the clamping member 410 is cylindrical, when the lifting rope 5 is clamped, the clamping member 410 can rotate.

Embodiment 3

[0043] Such as Image 6 As shown, the wind and wave resistant deep-water net cage can be raised and lowered, and the other structure is the same as the first embodiment except for the locking mechanism. In this embodiment, the cavity of the locking mechanism and the clamping member 41 are pyramids with similar shapes, and the clamping member 41 has a small volume so that the clamping member 41 can move up and down in the cavity. The upper end of the clamping member 41 is connected with one end of the control rope I 71, and the lower end of the clamping member 41 is connected with one end of the control rope II 72. Pulling the other end of the control rope I 71 or the control rope II 72 can make the clamping member 41 move in the cavity, jam or Loosen the lifting rope 5.

[0044] The limit block 42 is fixed on the control rope Ⅱ 72. The limit block 42 is close to the lower end of the clamp 41. The distance between the limit block 42 and the lower end of the clamp 41 is less than t...

Abstract

A deepwater net cage capable of being lifted and resisting wind waves comprises a bag net, a float bowl, a frame and an anchoring device. The bag net and the float bowl are fixed on the frame, and the frame floats by means of buoyancy of the float bowl and is connected with the anchoring device at a water bottom. The deepwater net cage further comprises a lifting device, the lifting device is connected with the frame of the net cage, and a lifting rope and a locking mechanism are arranged on the lifting device. The locking mechanism comprises a cavity, a clamping piece located in the cavity and a control rope. A fixed end of the control rope is fixed on the lifting device, a free end of the lifting rope penetrates through the cavity of the locking mechanism after penetrating through the anchoring device, the lifting device can move towards the anchoring device by pulling the free end of the lifting rope, the frame is driven to move downwards, and the frame rises by means of the buoyancy of the float bowl when the lifting rope is loosened. Two ends of the cavity are provided with openings for the lifting rope to penetrate, the clamping piece is connected with the control rope, the clamping piece can move up and down in the cavity by respectively pulling one end of the control rope, the lifting rope in the cavity can be clamped after the clamping piece moves downwards, and the lifting rope can be loosened when the clamping piece moves upwards. The deepwater net cage is simple and convenient to operate and labor-saving.

Description

Technical field [0001] The invention relates to an aquaculture device, in particular to a wind and wave resistant deep-water net cage that can be sunk into the water. Background technique [0002] Marine cage aquaculture is a highly intensive aquaculture method that applies dense-release intensive culture technology to larger water surfaces with superior environmental conditions to achieve high yields. The advantages are: rapid investment returns, high output, but also high risks. The main risk is that typhoons frequently hit the coastal areas of our country, causing the destruction of the cages. [0003] Most of the existing cages are floating row cages with simple structure and poor resistance to wind and waves. In order to avoid the impact of wind and waves from destroying the cages, a lift-type anti-wind and wave deep-water cage has appeared. The net of the cage can sink into the water, but its main frame is still floating on the water. When a typhoon strikes, the main frame i...
