Description

Water surface impeller

Technical field

The utility model relates to a kind of water surface impeller, mainly is applicable to the waters of mobile relative mistake, increases the water body flowability of water meter.

Background technology

Early summer in 2007, blue-green algae is broken out in waters such as China Taihu Lake, Chaohu in succession, becomes the focus that various circles of society pay close attention to for the moment.At present, body eutrophication is very general in China.Annual high temperature season, at the mobile relatively poor Hu Ku of water body, the higher local waters of water temperature blue-green algae just often may occur and assemble, and is called " wawter bloom " phenomenon.The outburst of wawter bloom big area directly causes aquatic attitude system equilibrated to destroy, and the growth of aquatic animals and plants is multiplied have devastating impact human safe drinking water around also usually influencing.

Along with social economy's high speed development and quickening of urbanization process, the water surrounding development is subjected to interference of human activities very violent, and normally keeping with the contradiction of mankind's activity of aquatic attitude system is very outstanding, and it is complicated more that the formation reason of wawter bloom becomes.For many years, because China's industrial or agricultural water consumption is huge, the water pollutant discharging is obvious to the lasting storage effect of the pollution of water body, for flood control, cut dirt, water resources utilization etc. to river course, Hu Ku carried out a large amount of curving cut-off, engineerings such as shop fixtures sclerosis, the water intaking that stops, self purification of water body and self-reparing capability can not be born the pollution load of warehouse-in far away, and therefore the wawter bloom phenomenon has become the unbalance a kind of common sign of aquatic attitude.

Studies show that wawter bloom is the coefficient result of multiple condition, these factors comprise:

1. water volume flow rate is less than 0.05 meter per second;

2. total nitrogen is greater than 0.2mg/L, and total phosphorus is greater than 0.02mg/L;

3. temperature is at 25 ℃--and 28 ℃, intensity of illumination is when the 350-500 μ E left and right sides;

4. the chlorophyll content in the water is more than 45.0～48.0 μ g.Chla/L;

5. subatmospheric can induce algae to float in a large number, gathers on the water surface, thereby forms wawter bloom.

The fundamental way of preventing and treating wawter bloom is to reduce pollutant emission, increase warehouse-in clean water, maintenance and the optimum aquatic attitude system of reparation.The various emergence control measures of taking at present then mainly launch around some factors that can manually improve, cultivate or the like as plug-flow, aeration, temperature exchange, bacterial classification.In the lake, river, carry out the artificial water cycle of sufficient intensity, can destroy the natural condition that wawter bloom takes place.Wherein the method for plug-flow allows water body flow, and increases the water body flowability of the following about 500mm scope of water meter, keeps the range of influence water body to be in permissible velocity and turbulent flow, suppresses the frustule growth, avoids frustule to assemble, and takes place thereby prevent and treat wawter bloom.And the present device of realizing the water surface plug-flow that also is not used in.

Summary of the invention

The purpose of this utility model just provides a kind of water surface impeller, so that produce the current that need at the water surface, satisfies water surface mobile needs.

The technical solution of the utility model is: comprise buoyancy aid assembly, plug-flow pipe, submersible machine and impeller, the plug-flow pipe is housed below the buoyancy aid assembly, in this plug-flow pipe submersible machine is housed, on the output shaft of this submersible machine impeller is housed; On described buoyancy aid assembly, ground tackle is housed.

On described buoyancy aid assembly, generator is installed, is provided with rain cover above the generator, be provided with the oil removal dish at the low side of this generator at this.

Described buoyancy aid assembly links beam by at least two buoyancy aids and at least two buoyancy aids and constitutes, and each buoyancy aid is parallel to be set up in parallel, and the buoyancy aid binding beam with arranged transversely on described buoyancy aid is fixedly connected.

Described buoyancy aid assembly is made of a buoyancy aid.

The water inlet of described plug-flow pipe is tubaeform extension mouth, and the water outlet aperture of this plug-flow pipe is less than water inlet.

The utility model has the advantages that: the direct impeller of its electric motor, plug-flow efficient height; Adopt water surface plug-flow mode, disturbance region is efficiently concentrated; Utilize the power supply of onboard generators or external source, the position is flexible, but layout area is wide; The portable installation, it is fixing to cast anchor, and not influenced by the depth of water and regional location; Can improve the water body dissolved oxygen concentration, promote the exchange of surface water and swallow interlayer, reduce sea surface temperature, the dilution nutrient concentrations.
