Description
Technical field
The present invention relates to the water bloom blue-green algae harvest technical field, more specifically relate to a kind of cofferdam device of anti-high stormy waves interception bloom blue algae, especially be fit to break out in lake and the reservoir and surround and seize behind the bloom blue algae and collect.
Background technology
In recent years, because industrial boom, population increase, urbanization increases the weight of, severe environmental pollution, the Eutrophic Extent aggravation of the many water bodys of China, cause the amount reproduction of algae, particularly blue-green algae, some water body even serious blue-green alga bloom occurs, but quality and the availability of water body directly affected, and endangering livestock and human health.In In Middle And Lower Reaches of Changjiang River lake and reservoir blue-green alga bloom occur in a large number the 4-10 month, especially maximum at the generation of the high temperature season blue-green alga bloom of the 7-9 month.A large amount of bloom blue algaes that occur are serious environment pollution, harm drinking-water water source on the one hand.For alleviating these pollution, eliminate the blue-green algae peculiar smell, be necessary the blue-green alga bloom of a large amount of outbursts is removed effectively.Adopt mechanical means to remove blue-green alga bloom, both do not had the such impact of chemistry and biology method, and can directly sweep off the blue-green alga bloom on lake or the reservoir water surface.Therefore, at a large amount of Growth seasons of blue-green alga bloom, adopting mechanical method that the blue-green alga bloom of bulk deposition is removed effectively is to prevent from worsening propagation and secondary pollution, and reduces thus Nutrition level, is very necessary thereby can reach the purpose of improving environment.Domestic have Jiangsu in Taihu Lake, Anhui in Chaohu, Kunming dropped into very large fund and manpower at reservoirs such as Dian Chi and Microcystins in The Dianshan Lake, the Yangtze River Gorges and gathered in the crops, effect is not very good, wherein one of the main reasons is exactly in the water bloom blue-green algae harvest process, often owing to the wind direction reason causes the water surface bloom blue algae floating indefinite everywhere, or after wind-force blows to blue-green alga bloom in a place and concentrates, wind direction changes in the results process, again algal tufa is blowed to that other are local or dispel, caused larger difficulty to results.Therefore, Many researchers utilize fence the blue-green alga bloom that breaks out is tackled or to be surrounded and seize at lake surface or reservoir.But the interception fence of surrounding and seize is often scraped fence during such as larger stormy waves disconnected easily.Affect interception result.How about make the fence of interception blue-green algae under high stormy waves condition, remain intact harmless.The report that does not also have to find to have document or patented technology about this respect both at home and abroad.The invention reside in the cofferdam that makes a kind of anti-high stormy waves interception bloom blue algae, bloom blue algae is effectively tackled.Make it not be subjected to the impact of high sea under high stormy waves condition, it is harmless that fence is remained intact, thereby greatly improved blue-green algae interception and efficiency of crop.
Summary of the invention
The objective of the invention is to be to provide a kind of cofferdam device of anti-high stormy waves interception bloom blue algae, this cofferdam device, simple in structure, easy and simple to handle, the efficient of catching bloom blue algae is high, and cost is low, has solved a large amount of accumulation problems of the algal tufa in the water bloom blue-green algae harvest.
In order to achieve the above object, the present invention adopts following technical measures:
Water body cofferdam device mainly contains the compositions such as foaming buoyancy aid, infantees, skirt body, reinforcing band, counterweight.Utilize the foaming buoyancy aid, make the buoyancy aid infantees in the buoyancy aid outside with corrosion-proof and high-strength degree synthetic rubber infantees, staying 500mm below the buoyancy aid infantees is the skirt curtain, a high-intensity nylon tape or rope is set as reinforcing band in the middle of the skirt curtain, adopts metal pair hook joint head to connect between the reinforcing band.Use iron chains as counterweight in skirt curtain 3 lower ends, fix with steel plate at the interface at two ends, every cofferdam, make a call to two row Φ 1.5cm holes on the steel plate, every row makes a call to 5 holes, wears in the manhole with nylon rope to connect, and is then connecting with the metal pair hook joint head on the reinforcing band.The cofferdam is connected with anchor with anchor line two joints, anchor is thrown into lakebed, and fence prevents cofferdam distortion, every 30m-40m on the both sides, cofferdam to throwing a pair of anchor.After anchor is thrown into lakebed, usefulness anchor line 8 and cofferdam integrated connection on the anchor, stretching fixing downwards, make it to become soft cofferdam.General every of water body cofferdam is 20 meters, and every has 13 of polyethylene foam buoyancy aids.Spacing between float forms compliant section, guarantees snakelike flowability and the rider of enclosure.The lower end that reinforcing band is set in the middle of the skirt body is furnished with iron chains.Guarantee that enclosure can freely move both vertically with the great waves the tide is flowing and ebbing all the time in water.Reinforcing band counterweight chains etc. are as the longitudinal stress member.Being connected between bar and the bar adopts the claim-reduction locking device or adopts American metal pair hook joint head.It is integrated that whole cofferdam is formed.(seeing accompanying drawing 1), water body cofferdam hermetically sealed adopts corrosion-proof and high-strength degree synthetic rubber infantees to make the buoyancy aid infantees, and the skirt body adopts highly corrosion resistant, and high strength enclosure cloth is used the iron chains counterweight.The below fixes with anchor.
The present invention compared with prior art has the following advantages and effect:
Compare with traditional interception bloom blue algae device, interception bloom blue algae device can effectively be tackled bloom blue algae, has solved the problem of interception bloom blue algae, can improve the amount of algae 90% that the interception bloom blue algae gathers.Easy to carry.Simple in structure, easy to use, with low cost, can effectively in the muddy water bodys such as river, tackle bloom blue algae, it is strong that the water body cofferdam has a capacity of anti-storm, good stability, operation is convenient, and high efficiency suits to lay in the water midium or long term.
