Abstract
The invention provides a double-layer flow guiding and intercepting oil containment boom. The double-layer flow guiding and intercepting oil containment boom comprises a short freeboard, a high freeboard and a double float with a trapezoidal cross section. Both the short freeboard and the high freeboard are arranged on the double float. Both the short freeboard and the high freeboard are arranged in the direction perpendicular to the trapezoidal cross section of the double float. Both the short freeboard and the high freeboard protrude out of the top face and the bottom face of the double float. The length of the part, protruding out of the top face of the double float, of the short freeboard is smaller than that of the part, protruding out of the top face of the double float, of the high freeboard. The length of the part, protruding out of the bottom face of the double float, of the short freeboard is smaller than that of the part, protruding out of the bottom face of the double float, of the high freeboard. Oil gathering grooves are formed in the outer side of the top face and the outer side of the bottom face of the double float in an enclosed mode through the short freeboard, the high freeboard and the double float. By the application of the technical scheme, the trapezoidal double float design not only greatly increases buoyancy force but also improves the system stability of the oil containment boom, enhances the anti-sinking and anti-flat-toppling capacity of the oil containment boom and guarantees smooth development of the oil containment boom and emergency rescue work.
Description
Technical field
The present invention relates to technical field of petroleum industry, to dam the oil fence in particular to the double-deck water conservancy diversion of one.
Background technology
In oil product and hazardous chemical leak of liquid (following unified abbreviation oil spilling) emergence technology field, the oil fence is spill containment equipment that is the most important, that be most widely used.Oil fence effect whether play by this body structure, water volume flow rate, wind speed, wave etc. in many ways factor affect.
The oil fence nearly all at present all adopts single float or single airbag design to originate as main buoyancy, and employing is gone alone side of a ship design and splashed and oil spilling escape under water to prevent water surface oil spilling.First this design cannot provide sufficient buoyancy, and center, hurdle and freeboard are at same plane, in flow velocity or the larger water body of stormy waves, because buoyancy deficiency is easily submerged to below the water surface, because crank easily occurs flat, cannot float by oil film gravity and tension force effect and lose efficacy.Secondly when oil spillage is larger, oil film thickness can increase sharply, and under wind wave action, oil spilling is easy to splash and even breaks through oil fence encirclement continuation diffusion; Moreover, along with the continuous increase of oil film thickness, the turbulent flow of especially high flow rate generation, can make oil spilling be sheared below oil film and escape from freeboard.In addition nearly all at present oil fence only can realize the effect containing oil spilling, the removing of oil product also needs the equipment such as supporting oil skimmer or oil scavenge pump to realize, not only do not make full use of resource, and once the removing of oil product is not carried out in time, continuous accumulation along with oil is easy to that the oil fence occurs and lost efficacy and oil spilling escape, and serious consequence occurs.
Therefore, invention one can provide powerful buoyancy and overstable center of gravity, and can effectively prevent oil spilling from waterborne and escape under water, and the oil fence simultaneously possessing oil pumping oil absorptive function is extremely necessary.The domestic report not yet having such device at present.
Summary of the invention
Main purpose of the present invention is to provide a kind of double-deck water conservancy diversion to dam the oil fence, easily below the water surface is submerged to solve the oil fence of the prior art due to buoyancy deficiency, because crank easily occurs flat, by the problem that oil film gravity and tension force effect cannot float and lose efficacy.
To achieve these goals, according to an aspect of the present invention, provide a kind of double-deck water conservancy diversion to dam the oil fence, comprise: short freeboard, two floats of high freeboard and trapezoid cross section, short freeboard and high freeboard are all arranged on two float, short freeboard and high freeboard are all arranged along the direction of the trapezoid cross section perpendicular to two float, short freeboard and high freeboard all protrude from end face and the bottom surface of two float, the length that short freeboard protrudes from the end face of two float is less than the length that high freeboard protrudes from the end face of two float, the length that short freeboard protrudes from the bottom surface of two float is less than the length that high freeboard protrudes from the bottom surface of two float, short freeboard, high freeboard and two float all surround oil-collecting groove with outer side bottom surface outside the end face of two float.
Further, the trapezoid cross section of two float is isosceles trapezoid.
Further, the distance of the middle section of short freeboard and the two float of high freeboard distance is equal.
Further, two float comprises two prismatoids be connected, and the bottom of two prismatoids connects as one, and the upper end of the connecting portion of two prismatoids forms the kerve of circular arc, and short freeboard and high freeboard are arranged on two different prismatoids.
Further, short freeboard and overrisen freeboard plane overlap with the middle section of two prismatoids respectively.
Alternatively, the end face of two float offers the kerve of circular arc, and kerve is arranged along the direction perpendicular to the trapezoid cross section of two float, and short freeboard and high freeboard are separately positioned on the both sides of kerve.
Further, the double-deck water conservancy diversion oil fence that dams also comprises stream guiding tube, and stream guiding tube is interposed in the kerve of two float, and stream guiding tube designs for opening, the shape of stream guiding tube and the shape of kerve suitable.
Further, the double-deck water conservancy diversion oil fence that dams also comprises many steel rib plates, and many steel rib plates are arranged in kerve at intervals, and the two ends of steel rib plate are fixed on two float.
Further, the double-deck water conservancy diversion oil fence that dams also comprises sealing side of a ship blanket, on the bottom surface that sealing side of a ship blanket is arranged on two float and between short freeboard and high freeboard.
Further, the overrisen part protruding from the bottom surface of two float offers sluicing counterweight hole.
Apply technical scheme of the present invention, trapezoidal pair of float design not only considerably increases buoyancy, and adds the stability of oil fence system, improve the anti-sinking of the oil fence, anti-flat fall ability, ensure carrying out smoothly of the oil fence and emergency management and rescue work.
