A kind of steel column pile type laver cultivation device in shallow water area

Abstract

The invention provides a steel pile type laver culture device in a shallow water area and belongs to the field of laver culture devices. The device includes steel piles uniformly distributed on a seabed, and each steel pile is sleeved with at least two floating rings; a culture net which is horizontally distributed is connected to the floating rings at the topmost ends of the steel piles, and suspension rods which are horizontally distributed are connected to the floating rings at the bottommost ends of the steel piles; net pieces and drying assemblies both of which are perpendicular to the culture net are uniformly distributed between the culture net and the suspension rods. By means of the device, the effect of thoroughly drying the laver is great, the stability of the device is high, the seedling drop rate is low, the growth rate of the laver during culture is calculated, and the manual work intensity can also be effectively reduced.

Description

technical field [0001] The invention belongs to the field of laver cultivation devices, and in particular relates to a steel column pile type laver cultivation device in a shallow water area. Background technique [0002] Seaweed is an important economic food, delicious and nutritious. According to the analysis of the Institute of Chemistry, Chinese Academy of Sciences, seaweed contains 31.3% of protein necessary for human body, 30.2% of water-soluble polysaccharides, 0.7% of fat and vitamin B 1 B 2 (and the trace elements zinc, manganese, iron, copper, etc. necessary for the human body), in addition to eating, it also has the effect of preventing and curing diseases, and is also an important raw material for the emerging agar industry. Zilai breeding has the characteristics of short production cycle, simple production operation, no damage to feed, low production cost and high income. It is an important way for coastal areas to make full use of coastal tidal flats, develop ...

AI Technical Summary

Problems solved by technology

[0003] There are many ways of cultivating laver, among which the fully floating raft culture laver is widely used, the methods of fully floating raft culture laver include "U" type full floating raft dry out culture method, tripod type full floating raft dry out culture method and overturning full floating rafts to dry out the breeding methods, and these methods have the following defects: the first, the above-mentioned breeding methods all need manual operation, labor intensity is high, difficult to operate at sea, and the time of drying also needs to be artificially controlled, which is very difficult. Difficult to grasp in time, affecting the growth of laver; second, poor resistance to wind and waves

The manually operated drying device is only fixed on the buoy in the laver cultivation area. As the laver field floats as a whole, there is no connection and fixed control between itself and the seabed. Therefore, the impact load on the root cable of the laver field is heavy, and the resistance to wind and waves is poor. , the floating raft made by manual operation, when supporting the net curtain, only supports the two end points of the net curtain. The force on the two points of the floating raft is unstable, and it is easy to roll over or tilt under the impact of wind and waves. It is not suitable for use in sea areas with strong wind and waves. The device Its own wind and wave resistance is also poor; third, the work is not thorough

When the manual operation is done, the wind and waves will cause the device to be unstable. Therefore, the center of gravity of these devices must be lowered. Under the action of the waves, the laver will not be dried completely; fourth, the mechanized vegetable picking cannot be carried out, and the efficiency is low.
