Embodiment 1

[0012] Embodiment 1: refer to figure 1 , combined lifting type raft farming device, including the rope 4 that is connected in the shape of a well, wherein: the force lines 42 of the working part of the rope 4 are arranged in parallel; The inflatable floating tube 1 is parallel to the force line 42; the inflatable buoy 11 is connected to the inflatable buoy 11 through a hose; the end of the force line 42 is connected to the buoy 3. The inflatable buoys 11 are arranged at both ends of the force grid 42 and combined with the pull of the densely distributed equal-length breeding slings 2, the inflatable floating tube 1 can be parallel to the force grid 42, and the inflatable buoy 11 can inflate or inject water into the inflatable buoy tube 1 The operation can make the inflatable floating tube 1 rise and sink independently, so as to realize the light control of the breeding objects in the natural sea area, and has a certain anti-wind and wave effect. Due to the application of the ...

Embodiment 2

[0013] Embodiment 2: refer to Figure 2 to Figure 3 , combined lifting type raft farming device, including the rope 4 that is connected in the shape of a well, wherein: the force lines 42 of the working part of the rope 4 are arranged in parallel; The inflatable floating tube 1 is parallel to the force line 42; the inflatable buoy 11 is connected to the inflatable buoy 11 through a hose; the end of the force line 42 is connected to the buoy 3. The end of the force line 42 also has a mooring buoy 41 . The mooring buoy 41 can make the force grid 42 always in a horizontal state, so that the spatial structure of the entire mooring system is stable, the force is uniform, the buffering effect is good, and it has high strength. Since the cost of materials used in the whole system is low, the realization cost is low, and there are no too many special components, thereby creating favorable conditions for large-scale promotion.

Abstract

The invention discloses a combined lifting type raft culture device. The combined lifting type raft culture device comprises ropes which are connected in a gridding shape, wherein the manropes of working portions of the roes are symmetrically distributed. Two groups of cultural lifting ropes which are symmetrically distributed between the manropes are connected with air-filled floating pipes, and the air-filled floating pipes are parallel to the manropes. Air-filled buoys are connected through flexible pipes, and end portions of the manropes are connected with floating balls. Due to the fact that the air-filled buoys are arranged at two ends of each manrope and are combined with pulling of densely distributed cultural lifting ropes with the same length , the combined lifting type raft culture device achieves that the air-filled floating hoses are parallel to the manropes, conducts air filling or water injecting operations on the air-filled floating pipes through the air-filled floating buoys, enables the air-filled floating pipes to independently ascend and descend so as to achieve illumination control of the cultural objects in a natural sea area and possess a certain anti-wave effect. The combined and lifting raft culture device has the advantages of being firm in structure and stable in space state, possesses the certain anti-wave effect, can achieve manual illumination adjustment in the natural sea area and is simple in craft and low in cost.

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 shell algae farming can not only provide a large amount of high-quality seafood for humans, 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 fram...
