Embodiment

[0012] Example: refer to Figure 1 to Figure 2 , combined lifting type raft culture device, including the floating tube 1 connected with the floating ball 2, wherein: the bottom of the floating tube 1 is suspended with the breeding cage 4 arranged along the floating tube 1 through the limit rope 5; the top of the breeding cage 4 A floating block 6 is provided; a sinker 3 is provided at the bottom of the breeding cage 4 . During use in sea areas, the floating tube 1 can effectively prevent the front and back extrusion of the breeding cage 4, the reduction of the breeding space, and the overturning of the cage body caused by the traditional rope method. The breeding space of the breeding cage 4 can be basically kept constant, and the spatial position is relatively stable, and the uneven distribution of the cultured shellfish due to the front and rear extrusion of the breeding cage 4 is avoided, thereby affecting the output. This design has larger aquaculture capacity and stable...

Abstract

The invention discloses a combined elevation and raft type cultivation device which comprises a floating pipe connecting with floating balls, wherein cultivation cages arranged along the floating pipe are hung below the floating pipe through limiting ropes; a floating block is arranged at the top end of each net cage; and a sinker is arranged at the bottom of each net cage. When the combined elevation and raft type cultivation device is used in sea area, the floating pipe can effectively avoid the problems that the cultivation cages are extruded forwards and backwards, the cultivation space is reduced, and the cultivation cage bodies are turned over, which are caused by using the traditional rope approach; the combined elevation and raft type cultivation device allows the cultivation spaces of the cultivation cages to be kept constant and the spacial position state of the cultivation cages to be relatively stable, so as to avoid production decline caused by uneven distribution of cultivation cages due to forward and backward extrusion when shellfishes are cultivated; the combined elevation and raft type cultivation device has a large capacity and a stable aquaculture water space; and the combined elevation and raft type cultivation device has the advantages that the structure is firm, the spatial state is stable, the process is simple and the cost is low, has a certain resistance to wind and waves, and can realize manual adjustment of lighting in a natural sea area.

Description

technical field [0001] The invention relates to a raft type culture device arranged in water, in particular to a combined lifting type raft type culture device. Background technique [0002] Appropriate development of shallow sea shellfish farming can not only provide a large amount of high-quality seafood for human beings, but also effectively control marine eutrophication and prevent red tides. It has significant ecological and environmental benefits and is a win-win human production activity. In addition, marine raft culture in waters with a water depth of -20 to -40 meters is conducive to the restoration and protection of offshore fishery resources. Therefore, the development of deep-water raft farming has important strategic significance and significant economic, social and ecological benefits to my country's food safety, ecological environment protection and improvement of people's living standards. In the prior art, the laver culture raft with floating bamboo as the ...
