Liftable multi-layer laver culture raft frame

Abstract

The invention discloses a liftable multilayer laver culture raft frame which comprises a buoy, one side of the buoy is fixedly connected with a connecting plate, one side of the connecting plate is provided with a clamping groove, the inner wall of the clamping groove is connected with a clamping plate in a clamped mode, the top of the clamping plate is provided with a positioning hole, and the inner wall of the positioning hole is rotatably connected with a positioning shaft. And one side of the buoy is fixedly connected with a fixed rod. The liftable multilayer laver culture raft frame is provided with a buoy, a fixing rod, a solar panel, an electric control system device box, a motor, a rope coiling device, a waterproof rope, a rope ring, a supporting disc, a supporting rod, a waterproof pad, a fixed pulley, a first traction rope and a culture net curtain. The waterproof rope can pull the supporting rod to move, the supporting rod can drive the culture net curtain to ascend and descend, the net curtain can be completely pulled out of the water surface, laver drying and exposing are fully completed, mixed algae are killed, and then damage to laver is reduced.

Description

technical field [0001] The invention relates to the technical field of laver culture, in particular to a liftable multi-layer laver culture raft. Background technique [0002] The cultivation of seaweed has the characteristics of short production cycle, simple production operation, no damage to feed, low production cost, high profit and high risk. It is an important way for coastal areas to make full use of coastal beaches, develop production, and get rid of poverty and become rich. The vast majority of seaweed culture rafts are single-layer culture and cannot be controlled to achieve dry dew to kill algal diseases. At the same time, the existing pillar-type and semi-floating seaweed culture rafts are generally exposed to drying and dew are limited by tides. Change, only in the shallow sea area, the breeding range is limited, multi-layer culture cannot be carried out, and the seaweed is very diseased and rotten. At the same time, the existing seaweed culture raft frame is ge...

Problems solved by technology

[0004] The object of the present invention is to provide a kind of liftable multi-layer laver culture raft frame, to solve the problem that the existing laver culture raft frame proposed in the above-mentioned background technology generally cannot control the raising and lowering of the culture raft frame to realize dry dew, and cannot carry out multi-layer culture at the same time. It is not possible to utilize diseased and rotten seaweed, and it is not convenient to connect individual farming raft units into rows according to the size of the farming sea area
