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 can be raised and lowered against wind and waves. The net cage includes a bag net, a buoy 2, a frame 1 and an anchoring device 6. Aquaculture can be carried out in the bag net. The bag net has a cover that can be opened and closed, and the sinking frame , the net cover is closed to prevent the fish from escaping, the buoy 2 is a hollow plastic bucket, the bag net and the buoy 2 are fixed on the frame 1, the frame 1 floats by the buoyancy of the buoy 2, the frame 1 is connected with the mooring device 6 at the bottom of the water, and the mooring device 6 It can be an anchor hook or a cement pile, etc. After the frame 1 is connected with the mooring device 6, the frame can be prevented from drifting away with the waves.

[0031] Described net cage also comprises hoisting device 4 and lifting rope 5, and hoisting device 4 and net cage frame 1 are connected by rope 3, and one end of hoisting rope 5...

Embodiment 2

[0041] Such as Figure 4 , Figure 5 As shown, the anti-wind and wave deep-water net cage can be raised and lowered. The clip of the locking mechanism is cylindrical, and other structures are the same as in the first embodiment. At both ends of the piece 410, since the clamping piece 410 is cylindrical, when the lifting rope 5 is clamped, the clamping piece 410 can rotate.

Embodiment 3

[0043] Such as Figure 6 As shown, the anti-wind and wave deep-water net cage can be raised and lowered. Except for the locking mechanism, other structures are the same as in Embodiment 1. In this embodiment, the cavity of the locking mechanism and the clip 41 are pyramid-shaped in similar shape, and the clip 41 is relatively small in size, so that the clip 41 can move up and down in the cavity. The upper end of the clip 41 is connected to one end of the control rope I71, and the lower end of the clip 41 is connected to one end of the control rope II72. Pulling the other end of the control rope I71 or the control rope II72 can make the clip 41 move in the cavity, block or Release the lifting rope 5.

[0044] The limit block 42 is fixed on the control rope II72, and 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 smaller than the depth of the cavity. When the clamp 41 moves upward and th...

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 submersible anti-wind and wave deep-water net cage. Background technique [0002] Marine cage culture is a highly intensive farming method that applies the intensive intensive culture technology to large water surfaces with superior environmental conditions to obtain high yields. The advantages are: quick investment and high output, but also high risks. The main risk is that there are often typhoons in the coastal areas of our country, causing damage to 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 wash...
