Description
Technical field：
The invention belongs to mariculture technology field, it is related to a kind of for anti-down streaming automatic feeding water unidirectional control device
The travelling ball of floating, particularly a kind of floating being applied to the automatic defeated unidirectional control device for filling seawater of seawater-culture pond are moved about
Ball, the global density of spheroid are less than the density of seawater, and using the tide energy of seawater, spheroid floats movement with the flowing of seawater,
Seawater is flowed into pond, and can effectively prevent that seawater flows backwards to outside pond when sea level fluctuationses are less than pool inner water position.
Background technology：
Sea-farming is the important component of aquatic products industry, is to utilize the waters such as shallow sea, beach, bay, pond cultivation sea
Foreign-water produces the production activity of Economic animals and plants, and its object cultivated is mainly fish, Shrimp waste, shellfish and algae etc., because extra large
The advantages of water cultivation is with the energy some economic values of centralized development higher marine animal and plant, so sea-farming extensively should
With.Currently used traditional cultural method has cage culture and pond culture, although cage culture conveniently moving, investment it is small,
It is to be had a great influence by stormy waves, easily contaminated, the product of cultivation is easily escaped, attached microbial, reduces breeding efficiency；Support in pond
A kind of mode of production for referring to that aquatic products Economic animals and plants cultivation is carried out using hand excavation or natural pond is grown, which needs
Using mode water fillings into pond such as artificial or water pump extractions, pond is stored into full water and carries out breeding production, also need timing concern pond
Interior SEA LEVEL VARIATION both takes manpower and materials, is also consumed by electric energy, waste of resource, this breeding way changes waterside number so as to water storage again
Less, limited with extraneous water coke slurry, water quality is poor, and the survival rate of aquatic products Economic animals and plants is relatively low.Therefore, seek to design a kind of use
In the travelling ball of the floating of anti-down streaming automatic feeding water unidirectional control device, density is placed in less than the travelling ball of the floating of density of sea water
In anti-down streaming automatic feeding water unidirectional control device, unidirectional control device is connected in sea with culturing pool, utilizes sea sea
The tide energy of water, as the tide rises, seawater is flowed to culturing pool, when ebb tide, float travelling ball and block passage, seawater can not flow backwards
Return greatly through the country, get through automatically daily, current exchange inside and outside progress, keep water cleaning, fishes and shrimps survival rate are improved, by tidal fluctuations
Caused sea water potential energy carries out auto-irrigation, reduces labor intensity, saves the energy and manpower.
The content of the invention：
The shortcomings that it is an object of the invention to overcome prior art to exist, propose that design one kind is entered automatically for anti-down streaming
The travelling ball of the floating of water unidirectional control device, to solve the problems, such as that artificial storage causes labor intensity big, overcomes traditional pond to support
Grow and change that waterside number is less, water quality is poor, the defects of causing the survival rate of aquatic products Economic animals and plants relatively low, solve traditional water pump water storage
Consume the energy it is big the problem of, effectively utilize nature tide energy, increase and utilize regenerative resource.
In order to realize foregoing invention purpose, the drift of the present invention for anti-down streaming automatic feeding water unidirectional control device
Swim dynamic ball, and its agent structure includes foam core, spherical shell, antirust coat, nylon mesh layer and rubber layer；Foam core is diameter 50
