Description
Technical field
The utility model relates to the device of a kind of water conservancy, water transport industry field water conservancy diversion, thereby realizes the floating flexible fluid-directing device of clearing sands with converging flow, beach protection and siltation promotion, river course (navigation channel) regulation in particular for the local flow-shape that changes river course, marine site.
Background technology
Normal engineering measure change current (trend), the sediment movement track of adopting in water conservancy, the water transport industry is to realize functions such as the short silt of beach, river course (navigation channel) regulation.Yet these engineering measures at present adopt rigid material to build more, such as stone, sandbag, concrete, steel structure etc., and typical section structure such as Fig. 3, the label 4 shown in the figure is described rigid materials; This engineering measure not only cost is high, and it is big that section takies water surface area, and careless slightly will causing than havoc ecological environment on every side, remedies difficulty.Therefore, engineering circle is being explored easy more light and handy, cheap guiding device always.
Find by prior art documents, Chinese invention patent publication number CN 1687530A, open day is on October 26th, 2005, application for a patent for invention numbers 200510026599.7, denomination of invention is: riverbed and sea bed silt are held back, the device of short alluvial protection against erosion, this patent be a kind of silt is slowed down and holds back on the spot realize the beach face alluvial, prevent the device that washes away, it comprises floating curtain, buoyancy aid, crosses screen window mouth, anchor member, buoyancy aid is located at floating curtain upper limb, cross the bottom that the screen window mouth is located at floating curtain, anchor member is located at floating curtain lower edge.During use, by floating curtain and the acting in conjunction of crossing the screen window mouth, form cross eddy at floating curtain back side, make the upstream come husky bed-sit being trapped after crossing the screen window mouth, silt is held back, the purpose of short alluvial protection against erosion thereby reach.Its weak point is: 1) because the bottom was provided with the screen window mouth, in force tidal bore power river mouth, marine site and the lower sea area of sand content, silt is not easy to deposit in the vortex of crossing screen window mouth back side, does not realize that silt holds back purpose; 2) because floating curtain is being connected on buoyancy aid and the anchor member of globality, cross the below that the screen window mouth is arranged at floating curtain, caused the local tensile strength of floating curtain sharply to reduce, buoyancy aid produces pulling force upwards under wave and tidal bore effect, is very easily crossing the generation tear failure of screen window mouth place; 3) the short silt effect that produces of this device only one of floating curtain back side more among a small circle in, and be that form with the husky bank in a kind of part exists, fundamentally can't resolve the purpose of protection against erosion.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming that exists in the above-mentioned prior art, and provide a kind of floating flexible fluid-directing device, this device is to be mechanism by changing large-scale current (trend) movement locus, and then realize the flow field state of change river course, ocean, realize functions such as clearing sands with converging flow, beach protection and siltation promotion, river course (navigation channel) regulation.
The technical solution adopted in the utility model is: it includes float, water conservancy diversion curtain, base, and described water conservancy diversion curtain upper limb is connected with float, and water conservancy diversion curtain lower edge is fixed in base.
Described float is the hollow seal body of floatability in water, and the quantity that this float is arranged and spacing are determined greater than the gross weight of float and water conservancy diversion curtain according to the uplift pressure that makes progress that float is submerged in the water to be produced fully; Described float is arranged continuously or is equidistantly arranged according to the water conservancy diversion direction.
Described float is 1～4m by the spacing of equidistant layout.
The flexible curtain structure that described water conservancy diversion curtain selects for use tensile strength to constitute greater than the making a concerted effort of current and tidal wave uplift force, by porous or grid or closing membrane.
The base that connects under the described water conservancy diversion curtain is the heavy beam of bar shaped or pile or damascene structures.
Adopt colligation between described water conservancy diversion curtain and the float or twine or welding or bonding connection, described water conservancy diversion curtain and base employing be cast-in-place buries underground or throws and bury underground or weld, or is adhesively fixed.
The beneficial effects of the utility model are: 1) cheap, technology is simple, helps the protection of ecological environment; 2) do not influence flood passage safety; 3) mechanism by water conservancy diversion changes whole flow field, realizes effects such as clearing sands with converging flow, beach protection and siltation promotion, river course (navigation channel) regulation, has good stable; 4) structure has good flexible, and it is strong to adapt to deformability; 5) be applicable to the estuary coast zone that tidal bore power and Wave power are powerful, the self structure stability is superior.
