Description

A kind of oil fence equipment with supporting structure

Technical field

The utility model belongs to marine environmental protection field, and in particular to a kind of oil fence equipment with supporting structure.

Background technique

The oil fence is referred to as oil boom in America and Europe, also known as oil barrier (oil barrier), is a kind of for intercepting water Face oil spilling reduces oil spilling diffusion, convenient for recycling oil spilling and reduces oil spilling to the equipment of the pollution of environment.

The development of the oil fence is earlier than nineteen fifty.The emergency that the oil fence is considered as in emergency circumstances when most beginning to use is arranged It applies, is mainly provided to the so-called petroleum bases such as oil plant, oil storage institute.The oil fence is as the convenient and fast tool for reducing pollution and gradually Gradually be taken seriously is at the end of the sixties, the beginning of the seventies.With the continuous development of the oil fence, the type of the oil fence is more and more, but The structure of the single oil fence is essentially identical.In addition to special designing, the chief component of the single oil fence are as follows: Fu Ti ﹑ skirt Body and counterweight.Floating body is also referred to as float, provides buoyancy for the entire oil fence, can float across the sea；Skirt body is the oil fence It is located at underwater part in overall structure, is the main part that total blocks oil；Counterweight chain is located at oil fence bottom, rises and increases The effect for adding total weight keeps the oil fence sagging vertically, unlikely to be submerged by water, and is generally made of the biggish material of density. The oil fence in practical sea area is joined end to end by the single oil fence one by one, and spill containment is lived, and encloses oily effect to play.

The oil fence currently used in the market is divided into the Solid Float Type Oil Containment oil fence, Inflatable oil fence, outer by structure difference The tension type oil fence, fence type oil boom, riverbank oil fence and fence post for preventing oil storage container fromb eing.The material of the oil fence imitates the oil spilling of the oil fence Fruit plays a part of can not ignore, and the common oil fence mainly uses the materials such as polypropylene, polyethylene, polyvinyl chloride (PVC), the material Material has certain flotation property, performance of cleaving, and can prevent oil spilling from spreading.Therefore, in actual use, the common oil fence Type has the Solid Float Type Oil Containment PVC oil fence, the solid float rubber oil fence, inflation rubber oil encircling rail, riverbank oil fence and prevents The fiery oil fence, the first two oil fence are the oils fence often laid, and the third oil fence is generally as Emergency use, seashore and Fence post for preventing oil storage container fromb eing also plays an important role in respective field.With the development of spread goods, advanced composite material (ACM) is continuous It comes out, substantially increases the oily efficiency of blocking of the oil fence, such as the novel adsorption oil fence, the decanter type oil fence, high stable formula are enclosed Oil barrier etc., but in practical situations, due to the effect of the more outside cause such as stormy waves, oil spilling Chang Huicong oil fence root edge stream It loses, boom failure occurs.In this case, the binary oil fence just comes into being.The binary oil fence is with two oils fence It is separated by a certain distance made of being connected and blocks oily structure, the principle of the binary oil fence is: due to water currents, in first oil fence A biggish whirlpool can be generated below, it can contain the oil spilling of first oil fence loss, make it between two oils fence Steady flow, meanwhile, oil spilling is also intercepted by second oil fence.In this way, the binary oil fence can intercept most oil spillings, Oily effect is blocked with good.

Foreign countries are on the high side for the design scheme of the oil fence.K-F.V.Wong et al. did sinusoid in open type water channel and enclosed Oil barrier blocks oily experiment.Because it lacks vertical barrier, it is highly prone to the influence of stormy waves etc., then makes oil fence efficiency It reduces.Then on this basis, to avoid the upper model problem, they have made other two kinds of models again, one is Add a vertical barrier under the sinusoid oil fence, another kind design is airfoil type, i.e., the oil fence of multiple vertical screen-wall.K- F.V.Wong and E.Barin et al. did the flexible oil fence system that a kind of oil spilling is collected in open type water channel, the system by One inclination oil fence and three traditional oil fence compositions, the skirt body for tilting the oil fence are fabricated from a flexible material, oil fence benefit Make skirt solid offsetting with the energy of incoming flow and obtains ideal tilt angle.J Lane et al. is in the bay Ohmsett also to a kind of new The oil fence system of design is tested, and oil fence system is made of three oils fence, and the first two oil fence is normal size, The skirt length of the third oil fence is long 1.5 times of the first two oil fence skirt, and experimental result is shown, in flow rate of water flow lower than 1.5 seas In/constantly, oil fence system can achieve 86.5% and block oily efficiency.Norway is also had developed a kind of novel using nylon fabric The oil fence, when oil spill accident occurs, this oil fence can sprawl rapidly 2 kilometers of length, can prevent within a short period of time Oil spilling diffusion.

The failure of the oil fence refers to oil spilling at the top of the oil fence or bottom is escaped, to make to block showing for oily efficiency reduction As.The monomer oil fence and the binary oil fence are two kinds of forms relatively common in current spill response, and two kinds of oils fence are using Biggish interception function all is played to oil spilling in the process, but all there is disadvantages for each.The monomer oil fence is in use process The easy run-off the straight of effect of middle wind-engaging, wave, oil spilling will escape from oil fence bottom or go out at the top of the oil fence.Binary encloses When in use, the greasy dirt overflowed from the previous oil fence can generate eddy effect to oil barrier, and the presence of two oils fence, which exacerbates, encloses Eddy effect between oil barrier can thus generate a large amount of oil droplets, and a large amount of aggregations of oil droplet can make oil fence overload, thus Generate entrainment failure.

So the utility model is studied the problem of easily tilting to the monomer oil fence, for the oil fence structure into Row transformation, makes the oil fence keep stable in water.
