The invention relates to the technical field of cage culture, in particular to a chain type net changing device and method for circulating water cage culture in a seawater pond.
Background
China is a fishery big country, aquaculture becomes the main fishery of aquatic product production, particularly aquaculture industry, and is a main guarantee for animal protein supply, but the status of the fishery big country in the world is established on an extensive production mode, and does not meet the requirement of sustainable development, in the process of fishery supply side innovation, the quality is improved, the efficiency is increased, the production mode of the aquaculture industry by using a circulating water net cage expands the new space of fishery development, and the aquaculture density and the quality of aquaculture products can be effectively improved. The two ends of the circulating water net cage culture device are surrounded by the filter screens, the requirement of seawater circulation and circulation in the net cage is met, algae and other microorganisms easily grow on the filter screens at the two ends of the net cage, the filter screens are easily blocked, the growth and accumulation of aquatic organisms for a long time can deteriorate the water quality in the box body, the water circulation in the box body is seriously hindered, the culture environment is worsened, the water body is aggravated, the oxygen content is reduced, and the growth rate and the survival rate of cultured fishes are influenced.
In order to solve the problems, various net cage culture devices are provided in the prior art. For example, the chinese patent application No. CN201820163596.0 provides a device for net cage cultivation, which can use ocean current energy or wind energy to drive a washing mechanism to drive a brush to clean the netting of a square net cage, and the netting cleaning mechanism is suitable for any square net cage with any length-width ratio, and has high cleaning efficiency, good effect and low use cost, but the power such as wind energy is not used for pond net cage cultivation to drive the brush to clean the netting, and the washing mechanism increases the complexity of the net cage structure.
Also, for example, chinese patent application No. CN201910880292.5 provides an automatic floating-in-sea cage culture system, in which an air pump is used to pump air into each set of air floating sleeves at the lower end of a hollow pile, and each set of air floating sleeves is inflated to expand to drive the whole culture cage structure to float, so that the floating-in-sea adjustment of the cage can be realized, and the floating impurities attached to the cage can be cleaned by a micro pump and a water pump. However, the method has two problems, on one hand, the whole aquaculture net cage structure is driven to float upwards by inflating and expanding the air flotation sleeve, so that the requirement on the support strength is extremely high, and the method limits the size of the net cage. On the other hand, the cleaning period is greatly limited, cleaning can be carried out only once in one culture period, and microorganisms attached to the net cage during each cleaning period still cause great pollution to the water quality of the net cage.
The invention further provides a modularized semi-submersible type marine fish culture platform as the Chinese patent with the application number of CN201910236932.9, which comprises a main structure, net wheels, net clothes, a rotating mechanism and a driving mechanism, wherein the rotating mechanism comprises the driving mechanism, the net wheels and a rotating shaft, the net clothes are fixed between every two net wheels, the net clothes are hung at two side ends of the adjacent net wheels, the net wheels of the modularized rotating unit are supported at the central part of the main structure through the rotating shaft, and the net clothes are driven to rotate through the net wheels. The invention adopts a net wheel structure, in order to ensure that the area of the whole net can be sunned in turn, the sea fish culture water level is intelligently lower than the central shaft of the net wheel, and the space utilization rate is only 50 percent; if the seawater level is higher than the central axis of the net wheel, the phenomenon that the net clothes in the central area of the net wheel cannot be sunned by the sun to cause blockage exists.
In view of the above, the inventor of the present invention has made an intensive conception aiming at many defects and inconveniences caused by the imperfect structural design of the above-mentioned net cage culture apparatus, and has actively researched, improved and tried to develop and design the present creation.
