Embodiment 1

[0017] Embodiment 1: refer to Figure 1 to Figure 3 , the anti-current and anti-wave culture raft, including the culture rope raft 1, wherein: any end of the culture rope raft 1 is connected with two force lines 2, and the free end of the force line 2 is connected with an auxiliary self-sinking pile body 6; this embodiment There is also a fixed pulley on the secondary self-sinking pile body 6, but the effect of this fixed pulley is little, can omit. A fixed pulley 4 is provided in the middle part of the force network 2, and the fixed pulley 4 is connected with a main self-sinking pile body 5; the part of the force network 2 located between the fixed pulley 4 and the auxiliary self-sinking pile body 6 is also connected with an inflatable floating body device.

[0018] The inflatable floating body device includes a traction float 3 and an inflatable tube 31; the traction float 3 is connected with a force line 2 rope; the traction float 3 is connected with an inflatable tube 31 c...

Embodiment 2

[0022] Embodiment 2: refer to Figure 4 , Most of the structures of the anti-current and anti-wave culture raft are the same as in Embodiment 1. On the basis of Embodiment 1, the inflatable floating body device of this embodiment is slightly different. Inflatable floating body device comprises traction float 3, balance pulley 7 and inflation pipe 31; The inflation pipe 31 that traction buoyant ball 3 is inflated. The function of the balance pulley 7 is to make the force line 2 between the main self-sinking pile body 5 and the auxiliary self-sinking pile body 6 form an approximate isosceles triangle shape with the seabed, which can balance the action angle of the force line 2 tension force, so that the main body The stresses of the self-sinking pile body 5 and the auxiliary self-sinking pile body 6 are dispersed and made more even.

Abstract

The invention discloses a flowing and wave resisting cultivating raft, comprising a cultivation rope raft; wherein any end of the cultivation rope raft is connected with two lacing lines, and the free end of the lacing line is connected with an assisting self-drowning pile body; a fixed pulley is arranged at the middle part of the lacing line and is connected with a main self-drowning pile body; an inflatable floating body device is connected at the part of the lacing line, between the fixed pulley and the assisting self-drowning pile body, and the inflatable floating body device in water hasdifferent angles according to the air-filling proportion of the inflatable floating body device, so as to further improve the anti-flowing performance; in addition, under the wave action, the inflatable floating body device is combined with the fixation of the main self-drowning pile body and the assisting self-drowning pile body, so as to lead the lacing line to slide on the fixed pulley and buffer part of wavy force; therefore, the flowing and wave resisting effect of the invention is improved greatly compared with the prior art; in addition, the operation is convenient, the raft is suitable for the usage in the production, and the safety is high.

Description

technical field [0001] The invention relates to a raft-type culture facility, in particular to a current-resistant and wave-resistant culture raft. Background technique [0002] At present, marine aquaculture activities are mainly concentrated in the waters within the 20-meter isobath near the coast, and the aquaculture activities in the sea areas between -20 and -40-meter isobaths are almost blank. The main reason is that these sea areas have high winds and strong currents. , The waves are fast, and it is not easy to set up raft farming equipment. With the decline of per capita resources year by year, the development of terrestrial agriculture is facing the dual pressure of dwindling arable land and increasing population, which poses a serious threat to food security. Therefore, there is an urgent need to carry out research on anti-wind and wave technology in high sea state waters and large-scale ecological breeding technology, integrated innovation and industrialization d...
