Description

Rotary aerator for use in large water area fishponds

The utility model belongs to the fishery machinery field.

Breed fish in the fish pond, shrimp, often need be to water body oxygenation, and for the method for fishing pool oxygenation has a variety ofly, dividing by the oxygenation principle has electrochemical oxygenation, biochemical oxygenation, photochemical oxygenation, magnetization oxygenation and mechanical enhancement etc.Wherein mechanical enhancement uses at most, and the form of mechanical enhancement has vane type, propeller type, Waterwheel-type, jetting type, water jet, inflatable etc. several.In the majority from the type of service of above aerator with the Fixed Point Operation form, and the less employing of mobile operation form is also less to the research of mobile operating oxygenation.The weak point of aerator Fixed Point Operation is: load area is little, and oxygenation is inhomogeneous.The Fixed Point Operation aerator load water surface is generally 5-10 mu, in this scope apart from aerator than the far water territory, when summer, cultivation density was higher.Oxygen dissolving value under critical value, at this moment mainly moves about to aerator and keeps its life by fish, shrimp, has influenced the growth of fishes and shrimps like this.Even cause a large amount of fishes and shrimps death.And at aerator place waters 10m ²-20m ²In the scope, disorderly flow region for biphase gas and liquid flow, the water body dissolved oxygen is abundant in the zone, but because the strong disorderly effect fishes and shrimps that flow are difficult to enter this district, again owing to water body dissolved oxygen in this zone is very abundant, continue difficulty of dissolved oxygen, thus not the oxygen part that is absorbed by liquid with the form effusion water surface of air.In this case, on the problem that solves big water surface fishing pool oxygenation, the effort that any raising separate unit fixed operation formula aerator oxygen transfer rate solves problem is all got half the result with twice the effort, and uses many aerators, causes the new problem that scale of investment is big, installation and maintenance work increases the weight of, energy consumption is big again.In view of above situation, the home and abroad has worked out several aerators that can mobile oxygenation.

Russian Patent SU411813 proposes a kind of usefulness one cover connecting rod and adjusts the position of aerator in water, realize the purpose of mobile oxygenation, but oxygenation area is still limited, and complex structure is adjusted inconvenience.How Chinese patent CN85200914 jetting type fishing pool aerating machine, CN2039504 all be that the water effect that pushes away or the ejector injection high-speed gas-liquid mixture generation reaction force that utilizes screw to rotate to produce moves aerator with injecting type oxygen-increasing sprinkling ship, CN2039902 " suctions-pressures " formula aerator (ship) and the CN87213445 Jet-flow oxygen increasing device etc. of aerating vessel, CN2072324 band rudder, these aerators have need the manpower controlling party to; The installation rudder that has is controlled the course, but this control blindness is very big, and the effect of wind, wave is easy to make aerator to hit bank and maybe can not walks by design route.Moreover these aerator majorities are installed on the hull and use diesel engine to be used as power, and cause complex structure, and cost height, diesel oil easily pollute the problem of the water surface.The floating type voluntarily Jet-flow oxygen increasing machine that Chinese patent CN87211114 announces, control the motion of the aerator main body of forming by immersible pump, ejector with rope, this device is easy to the influence of wind-engaging, wave and other subtle disruption, and problems such as rope, cable and body winding take place, be difficult to reach the degree of normative operation.The wind-force self-propulsion type aerator that Chinese patent CN87209266 announces is formed its complex structure, wind mill and hull cost height by wind mill, the miscible pump of gas-liquid, dissolving, two-stage De Laval noz(zle) and water inlet pipe air inlet pipe, hull and rudder etc.Because the unidirectional of wind-force, there is being wind weather wind-force to make its cisco unity malfunction to the bank that whole unit blows to down wind, and when calm weather, wind mill can not produce power again, as use diesel engine to be used as power, the cost of complete equipment is higher, and exists the problem of contaminated by diesel oil water quality.The rotary aerator of two-wheel that Chinese patent CN86206535 announces is delivered to the rotation that is fixed on centre of gyration place electromotor on the impeller automatic aerator of two balanced configurations with angular wheel and two transmission arms, impeller automatic aerator in its wheel rotation also wraparound commentaries on classics center this device that revolves round the sun increased by two cover bevel gears, two power transmission shafts and axle sleeve than general aerator, cost increases more, and the revolution radius can not be too big, and oxygenation area improves limited.Automatic shift jet gas injection type aerator and rotary type impeller automatic aerator that Chinese patent CN87204059 and CN2035751 announce, its aerator main body all can rotate around fixed point, have enlarged oxygenation area and have solved the problem of making aerator power with electric energy.But also there are a lot of problems.The former, its rotation electricity bolt end that connects electric rotation controller is a rotating disc type, this version is unfavorable for installing rolling bearing.If the employing sliding bearing need come lubricating bearings with lubricating oil, easy polluted water and often to annotate the lubricating oil operation extremely inconvenient.Its electric rotation controller that connects is mounted on the timber, and the installation of timber is again a problem like this, and piling is relatively more difficult in water.When fishing pool bottom soil property was softer, it is dark that timber is squeezed into earth 05m, can not guarantee system stability and work safely.Because the effect of centrifugal force, wind-force and the surge power produced is rotated at aerator main body wraparound commentaries on classics center, timber connects electric rotation controller and falls into the water in case tiltedly fall, and will produce short circuit, and damage equipment is electrocuted the serious consequence of fish, shrimp.The latter, its revolute pair is by being fixed on copper electricity ring in three roads on the electric ring seat mandrel and three brush formed on its housing.Its three is fixed on brush on the housing.Like this, owing to make morpheme error such as the concentricity cause and circularity and, also just can not guarantee normally to transmit electric power, burn electromotor easily because the wearing and tearing of the electricity ring that wearing and tearing cause, brush all make the electricity ring can not contact well with brush.Its revolute pair is installed on the floating drum of location in addition, and the location floating drum is fixed in the water by three fixed legs and three tension ropes.Three fixed legs are difficult to fix with water-bed earth.In addition because the variation of the water surface elevation that rainwater causes causes the fluctuation of float-level height to make the effect of three fixed legs and floating drum conflicting.Three tension ropes are difficult to install in the big water surface fishing pool, act on also very limited.

At the problem that big water surface fishing pool oxygen increasing equipment exists, the utility model proposes a kind of being easy to and make, cost is low, installs easy to adjustly, and the unit load area is the big water surface fishing pool oxygen-increasing device of 10-80 mu.
