Description
Technical field
The present invention relates to technical field of petroleum industry, dam the oil fence in particular to a kind of double-deck water conservancy diversion.
Background technology
In oil product and hazardous chemical liquid leakage (unifying abbreviation oil spilling below) emergence technology field, the oil fence is the most
Spill containment equipment that is important, being most widely used.Whether oil fence effect is played by this body structure, water volume flow rate, wind speed, ripple
The multi-party factor such as wave affects.
The almost all of oil fence adopts single float or single airbag design to originate as main buoyancy at present, adopts
Go alone side of a ship design and escaped with oil spilling under water with preventing water surface oil spilling from splashing.Design this first cannot provide the buoyancy of abundance,
And hurdle center and freeboard are in same plane, in the larger water body of flow velocity or stormy waves, as buoyancy deficiency is easily submerged to water
Below face, as crank is susceptible to put down, cannot be floated by oil film gravity and tension force effect and be failed.Secondly in oil spilling
When measuring larger, oil film thickness can increase sharply, and under wind wave action, oil spilling is easy to splash or even break through the oil fence and surround continue
Diffusion；Moreover, the turbulent flow that being continuously increased with oil film thickness, especially high flow rate are produced, can make oil spilling in oil
Sheared below film and escaped under freeboard.In addition the almost all of oil fence can only be realized containing the work of oil spilling at present
With, the removing of oil product also needs to the realization of the equipment such as supporting oil skimmer or oil scavenge pump, does not only make full use of resource, once and
Being removed without of oil product is carried out in time, as the continuous accumulation of oil is easy to oil fence failure and oil spilling is escaped, is occurred tight
Weight consequence.
Therefore, invention one kind can provide powerful buoyancy and overstable center of gravity, and can effectively prevent oil spilling from waterborne
Escape under water, the oil fence for being provided simultaneously with oil pumping oil absorptive function is extremely necessary.Not yet there is the report of such device the country at present
Road.
The content of the invention
Present invention is primarily targeted at provide a kind of double-deck water conservancy diversion dam the oil fence, to solve of the prior art to enclose oil
Hurdle is easily submerged to below the water surface due to buoyancy deficiency, as crank is susceptible to put down, is made by oil film gravity and tension force
With the problem that cannot float and fail.
To achieve these goals, the oil fence according to an aspect of the invention, there is provided a kind of double-deck water conservancy diversion dams, bag
Include：Double floats of short freeboard, high freeboard and trapezoid cross section, short freeboard and high freeboard are arranged on double floats, short freeboard and height
Freeboard is arranged along the direction perpendicular to the trapezoid cross section of double floats, short freeboard and high freeboard protrude from the top surface of double floats and
Bottom surface, short freeboard protrude from the length that the length of the top surface of double floats protrudes from the top surface of double floats less than high freeboard, short freeboard
The length for protruding from the bottom surface of double floats is less than the length that high freeboard protrudes from the bottom surface of double floats, and short freeboard, high freeboard are double
Oil-collecting groove is surrounded with outer side bottom surface on the outside of the top surface of float.
Further, the trapezoid cross section of double floats is isosceles trapezoid.
Further, the distance of the middle section of short freeboard and the double floats of high freeboard distance is equal.
Further, double floats include two prismatoids being connected, and the bottom of two prismatoids connects as one, two
The upper end of the connecting portion of prismatoid forms the kerve of circular arc, and short freeboard and high freeboard are arranged on different two prismatoid
On.
Further, short freeboard and overrisen freeboard plane are overlapped with the middle section of two prismatoids respectively.
Alternatively, the top surface of double floats offers the kerve of circular arc, and kerve is along perpendicular to the trapezoid cross section of double floats
Direction arrange, short freeboard and high freeboard are separately positioned on the both sides of kerve.
Further, double-deck water conservancy diversion dams the oil fence also including stream guiding tube, and stream guiding tube is interposed in the kerve of double floats
In, stream guiding tube is open design, and upward, the shape of stream guiding tube is adapted opening direction with the shape of kerve.
Further, double-deck water conservancy diversion dams the oil fence also including many steel rib plates, and many steel rib plates are set at intervals
Put in kerve, the two ends of steel rib plate are fixed on double floats.
Further, double-deck water conservancy diversion dams the oil fence also including sealing side of a ship blanket, seals the bottom surface that side of a ship blanket is arranged on double floats
Go up and be located between short freeboard and high freeboard.
Further, sluicing is offered with repeated hole on the part of the overrisen bottom surface for protruding from double floats.
Using technical scheme, trapezoidal pair of float design not only considerably increases buoyancy, and increased and enclose oil
The stability of hurdle system, improves the anti-sinking of the oil fence, anti-flat ability, it is ensured that it is smooth that the oil fence and emergency management and rescue work
Carry out.
