Overturn prevention unit in solar aeration system

Technical Field

The invention belongs to the technical field of environment, and relates to an overturn-preventing unit in a solar aeration system.

Background

China is a large alga breeding country, the main alga breeding yield accounts for more than 80 percent of the world, and the alga breeding method is an important economic component of China. However, in recent years, the temperature of seawater has been increased and the cultivation method has become inappropriate, so that problems such as large-scale diseases of the seaweed occur during harvesting, and the quality and yield of the seaweed are reduced. The bottom layer low-temperature water body rich in nutrient salt is very suitable for the growth of seaweed. Scientific research shows that: the bottom layer seawater is lifted to the surface layer of the ocean by the seabed aeration, so that the surface layer oligotrophic salt seawater can be enriched, the ocean primary productivity is stimulated, and the ocean fishery yield and the carbon sink are increased. The technology is applied to the seaweed culture area, and can solve the problem of a large amount of rottenness of the seaweed in the harvest period of spring, thereby achieving the effects of improving the water environment and increasing the yield of the seaweed; meanwhile, the bottom layer of eutrophic salt seawater is brought into the true light layer, the growth of microalgae and the like is promoted, the primary productivity is improved, and the seawater is natural bait for fishes, shrimps, shellfishes and the like, is transmitted through a food chain and is beneficial to resource maintenance. In addition, the water in the low-temperature bottom layer can effectively reduce the water temperature in the surface layer, and a good temperature condition is created for the growth of the seaweed.

In addition, in the process of culturing the seaweed, along with the gradual increase of the fresh weight of the seaweed, the culturing raft frame sinks gradually, so that the seaweed at the bottom of the culturing raft cannot obtain sufficient light, and the yield and the quality of the seaweed are reduced.

The invention discloses a Chinese patent of an air-charging and exhausting type buoy lifting shellfish culture raft frame, with an authorization number of CN201733717U, and discloses a system for adjusting a culture raft frame by using an air-charging and exhausting mode. The floating pontoon is inflated to adjust the buoyancy, so that the height of the cultivation raft is changed in the cultivation process, and sufficient illumination is ensured.

The above techniques do not address how to implement an offshore aeration system. The existing aeration systems are all used on land, such as aeration of fish ponds, lakes, riverways and the like. The aeration systems cannot be used in mariculture areas at present, wherein the biggest limitation is that the marine environment is complex, the common aeration systems are easy to overturn and the like, and the function is single, so that how to design a stable and reliable aeration device which works for a long time is one of the key points for improving the problems of the mariculture areas.
