Description
Technical field
The utility model belongs to technical field of aquaculture, is specifically related to a kind of device that contributes to blowdown and have oxygen-supplying function.
Background technology
In technical field of aquaculture, oxygen content in water body concerns to the growing state severity of aquatic, slight hypoxia may cause the fishes and shrimps of cultivation to occur the morbid state such as floating head, when serious, even there is the phenomenon of full pool death, therefore breeding water body is carried out to the conventional method that artificial oxygenation operation is aquaculture field always.Existing aerator has vane type, Waterwheel-type, jetting type, water jet, inflatable, suction-type aerator etc., wherein application paddle aerator rather widely, its general principle is all to stir water body by impeller, fresh air in atmosphere is dissolved in water, thereby reach the object of oxygenation; Upper water is pressed to lower floor by the impeller of rotation simultaneously, both fresh air conveying gone down, again by the toxic emission at the bottom of the pool out; When heat, the upper and lower water layer temperature difference is large, stirs water body and also can make water temperature balance.
But, irregularly shaped due to culturing pool, and raiser to lay aerator position undesirable, and inevitable a large amount of food-residue animal excrements that produce of culturing pool etc. have had a strong impact on Water quality when actual cultivation operation, make existing oxygen increasing equipment in use have some intrinsic shortcomings: 1, the following shallow-layer of water surface place has obtained oxygen, water body bosom but severe depletion of oxygen causes aquatic livestock floating head even dead.2, oxygen increasing equipment can only be controlled circulating of water body, but can not control the whirlpool point of water body, and residual spot thing can not be deposited in to centrality sewage draining exit place conventionally, cause and can not in time residual spot thing be discharged outside culturing pool, to such an extent as to water quality environment worsens.3, the electric motor that is arranged on the water surface contacts and easily causes short circuit or damage with water body for a long time, while placement for a long time, also can get rusty, be not easy maintenance, has increased the financial burden of repairing, purchase.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of device that contributes to blowdown and have oxygen-supplying function, in dissolved oxygen amount, aquatic livestock ight soil, residual feed etc. in breeding water body can also be concentrated on to the position of specifying and be discharged outside culturing pool promoting water body to circulate to increase in breeding water body.
In order to realize foregoing invention object, the technical scheme that the utility model is taked is as follows:
Contribute to blowdown and have the device of oxygen-supplying function, comprise motor and screw, driven by motor screw rotates, it is characterized in that, described screw, perpendicular to culturing pool bottom, is Reducing screw shape structure, blade around central shaft along vertical direction helical form to downward-extension; Oar face external diameter maximum topmost, downwards continuous progressive dwindling.
Further, described motor is arranged on the water surface, and motor is connected with screw by connecting axle; Screw is fixedly connected with connecting axle lower end; On the oar face of screw, some through holes are set.
Further, described oxygen-increasing device also comprises bracing or strutting arrangement, and described bracing or strutting arrangement comprises bracing frame and support bar; Support bar is more than three, and evenly circle distribution is in connecting axle surrounding; Bracing frame is sleeved on connecting axle, and above-below direction position limits, and periphery is fixedly connected with support bar.
Further, between above-mentioned bracing frame and connecting axle, tumbler is set.
Further, described connecting axle top arranges mounting platform, fixes for the installation of motor case body.
Further, the water depth of described connecting axle length and culturing pool adapts, and its lowermost end is arranged on innermost sewage draining exit place at the bottom of culturing pool.
The beneficial effects of the utility model are mainly: 1, start screw and will produce large-area whirlpool, directly drive water circulation to produce the effect of waterfall water oxygenation, a large amount of bubbles that the lip-deep perforation of screw simultaneously produces while rotation can increase water body dissolved oxygen well, thereby solve the inadequate problem of water body depths dissolved oxygen, reduce the loss that aquatic livestock is caused because of anoxic.2, unique screw shape, when rotation, top large scale blade has ensured the generation of whirlpool, the structure that shrink bottom can not stirred large-area impurity at the bottom of pond; The moment that screw stops operating, the residue in culturing pool can be deposited in to centrality screw below; And oxygen-increasing device is arranged on bosom at the bottom of culturing pool, namely sewage draining exit place, makes to be deposited on that the dirt of screw below is convenient discharges along sewage draining exit, has ensured the water quality of breeding water body.3, motor power device case is arranged on the water surface, has avoided electric motor to contact with water body for a long time, can postpone its service life, the financial burden that reduces maintenance and repair and again buy.4, simple in structure, between all parts, can be connected and fixed by screw etc., install, safeguard, remove, transport, deposit etc. all more for convenience.
