A floating large-scale seaweed cultivation device

Abstract

The invention discloses a floating large-scale seaweed cultivation device, which includes a raft frame, a fixed pile and a rod. The raft frame includes a main floating pipe and a flexible connection auxiliary floating pipe assembly. The flexible connection floating pipe assembly includes several auxiliary floating pipes and springs. A partition is fixed inside the auxiliary floating tube, and the partition divides the inner space of the auxiliary floating tube into two spring chambers. The spring chamber is provided with a spring seat, and the lower end of the spring sleeve is placed on the spring seat. There is a connecting rod in the spring chamber. One end of the rod is fixedly connected with the spring seat, and the other end passes through the auxiliary floating tube. The end of the connecting rod outside the auxiliary floating tube and the positions near the ends on both sides of the main floating tube are equipped with shackles. The tube and the main floating tube are connected by tension springs, the two ends of the main floating tube are connected with pile ropes, the pile ropes are connected with the fixed piles, the resting rod is fixed on the auxiliary floating pipe, the rod is provided with a seedling rope, and the two ends of the seedling rope It is fixedly connected with the main floating pipe, and the seedling rope is hung under the rod. The invention has good stability, can avoid mutual entanglement and collision between the raft frame and the seedling rope, reduces the rate of seedling drop, and has strong wind and wave resistance.

Description

technical field [0001] The invention relates to a seaweed cultivation device, in particular to a floating large seaweed cultivation device. Background technique [0002] With the development of the metal mining industry, a large amount of heavy metals such as arsenic, lead, zinc, cadmium, and copper are discharged into seawater. Once heavy metals are absorbed into the food chain, they will eventually accumulate in organisms and eventually endanger human health. The marine environment, especially The heavy metal pollution in coastal waters has become a problem that human beings must face all over the world. In addition, my country's mariculture industry has developed vigorously, and the mariculture industry has gradually transitioned from the original sporadic free-range culture to intensive cage culture. This transformation of the breeding mode has played a very positive role in the economic development of the farming industry; at the same time, due to the high breeding den...

Problems solved by technology

[0004] Now the large-scale seaweed cultivation usually adopts a fixed raft frame (the raft frame is rigidly connected). It is prone to impact and entanglement, which can easily cause seedling drop
