Problems solved by technology

The ability of existing cage culture to resist wind and waves is relatively poor, and the ability to resist typhoon is relatively poor; meanwhile, the cages are generally square and connected together, causing the water flow in the cage to be not smooth, the external seawater is difficult to enter the inside of the cage, and the outside of the cage is lacking. To protect the frame, the stability of the cage is not high; in addition, the artificial dependence of the existing cage culture is relatively large

Embodiment 1

[0025] see Figure 1-5As shown, the anti-wind and wave type breeding net cage device includes a net cage frame 1, and the net cage frame 1 is evenly distributed with connecting ropes 9 connected with sinkers 30. 1 is provided with criss-cross sub-grids 6 to form a plurality of breeding areas. The buoy 2 includes the upper floating block 202 and the upper floating block 201 with built-in air pumps respectively. The trachea b28 is connected, and the upper floating block 202 and the upper floating block 201 are also provided with a flexible pipe 204 to connect with the floating ball 203, and buoys are evenly distributed on the outer peripheral surface of the net cage frame, so that the net cage can be suspended in water for fish fry cultivation. There are criss-cross sub-grids, which can realize the cultivation of fry in the net cage according to different specifications. At the same time, the buoys are set to include the upper floating block and the upper floating block with bui...

Embodiment 2

[0031] Such as Figure 6-7 As shown, the optimization scheme of this embodiment on the basis of Embodiment 1 is: sub-grid 6, including plastic round tube 12, a plurality of magnetic strips 11 are fixedly installed on the upper end of plastic round tube 12, and the adjacent magnetic strips 11 Magnetic mutual repulsion, plastic round pipe 12 one side is provided with the electromagnet rod 10 that is arranged in parallel, and plastic round pipe 12 lower end is connected with main net clothing 15, and electromagnet rod 10 lower end is connected with secondary net clothing 13, and electromagnet rod 10 one end is provided with crank connection Rod 7, is provided with electric control button 8 on crank connecting rod 7. A plurality of magnetic strips are fixedly installed on the upper end of the plastic round tube, and the magnetism between the adjacent magnetic strips repels each other. There is an electromagnet rod arranged in parallel on one side of the plastic round tube, so that...

Embodiment 3

[0037] The working principle of the anti-wind and wave breeding net cage device of the present invention is: place the device in a designated breeding area for fish fry cultivation, start the water pump 3, pump the water in the net cage out and spray it into the net cage again through the jet pipe 17 distributed on the steel pipe 16 In this process, the water outside the net cage can increase the flow rate of water into the net cage in a short time, promote the material exchange between the various water layers in the net cage, and make the distribution of nutrients in the net cage even. The fixed bar 5 that is provided with inclination further strengthens the intensity of net cage framework, increases the wind and wave resistance ability of net cage, night, fixed bar 5 built-in introduction insect light source 22 projections in water, can attract microorganisms in the water to enter in the net cage, so that For fry foraging, after 2-3 breeding cycles, by controlling the electr...

Abstract

The invention discloses a wind and wave resistant type aquaculture net cage device, which comprises a net cage framework. Connection ropes are uniformly distributed on upper and lower surface of the net cage framework and connected with sinkers, floats are uniformly distributed on the outer periphery of the net cage framework, and the net cage framework is internally provided with criss-cross partition grids to form a plurality of aquaculture areas. Each float comprises a first upper floating block and a second upper floating block, wherein air pumps are arranged in the upper floating blocks which are communicated through an air inlet pipe a and an air inlet pipe b. The floats uniformly distributed on the outer periphery of the net cage framework enable a net cage to suspend in water to realize fish fry aquaculture; by the criss-cross partition grids in the net cage framework, specification based aquaculture of fish fry in the net cage can be realized. By arrangement of the floats, thedevice has functions of automatic turning and own sinking and floating control.

Description

technical field [0001] The invention belongs to the technical field of aquaculture, and in particular relates to a wind and wave-resistant breeding cage device. Background technique [0002] my country's marine resources are very rich. With the development of economy and the continuous improvement of users' living standards, the demand for marine aquatic resources continues to increase. As a healthy food, fresh aquatic products have become a favorite of large, medium and small cities, restaurants and the general public. One of the preferred varieties. However, due to overfishing after the 1970s and 1980s, fish resources were seriously damaged, and with the continuous development of industrialization, offshore pollution further increased the decline of natural fish resources. Therefore, it is impossible to meet the market demand for seafood by relying on natural fishing methods alone, nor can it guarantee the sustainable development of marine fisheries. [0003] In order to ...
