Description

The utility model relates to environmental protection during the technical operation of oil trunk pipelines, namely, to means for localizing oil or oil products spilled on the water surface for subsequent trawling them to the extraction (sorption) site.

Permanent buoyancy booms (BZPP) are designed to localize and prevent the spread of oil, oil products and other pollutants in flowing and non-flowing water bodies (rivers, lakes, canals, ponds) with flow speeds up to 2.5 m / s and wavelengths up to 0, 3 m in the ice-free period.

It is known (RU, patent No. 39899 U1) a boom barrier, which includes separate sections, consisting of cylindrical floats, equipped with a skirt in the lower part with a ballast in the form of a chain skirt located in the pocket. The disadvantages of this design are the use of inflatable floats, as well as the use as a ballast chain.

It is known (SU, copyright certificate No. 1361244 A1) a boom barrier for collecting oil from the surface of the water, comprising interconnected sections of elastic material, each of which contains a float made in the form of an air cavity, the middle part connected to the float in the form of a vertical screen and located at the bottom of the cable section. This device, equipped with guides arranged in the form of through pockets located on a vertical screen, is intended mainly for collecting oil and has a rather complicated structure. The use of air floats increases the likelihood of product failure, and also requires the use of auxiliary equipment for supplying air to the floats.

The closest in the set of similar essential features is the fencing adopted for the prototype (RU, copyright certificate No. 1465488 U1) to prevent oil and oil products from spreading over the water surface, including separate hermetically connected sections with cylindrical floats enclosed in an apron shell (skirt from rubberized oil-resistant fabric), along the lower edge of which a traction rope is laid. The main disadvantages of the known boom barriers that prevent the following basic and additional technical results from being obtained: the long installation time of the boom and its high probability of failure due to the use of inflatable floats; Significant weight of the structure due to the large section length (50 m); the performance of the mechanical seal of the shell in the form of a rolled sheet with an external lacing.

The task, the claimed utility model is aimed at solving the bark, is to modernize the existing boom barriers to localize oil or oil products spilled on the water surface

The main technical result that can be obtained by realizing useful is to increase the reliability and stability of the boom.

The specified technical result is achieved due to the fact that the boom includes hermetically connected sections with cylindrical floats in the form of rolls of foam polyethylene enclosed in a fabric sheath with a skirt, while galvanized cables are laid along the upper and lower edges of each section, and on the lower cable fixed lead weights.

Due to the placement of the power element (upper cable) in the surface of the boom and ballast (lower cable) - in the underwater, as well as an additional uniform load of the lower cable, the stability of the whole structure is increased, which allows it to be used at river flow rates of more than 2.5 m / from.

The increase in water pressure on the underwater part of the boom at river flow speeds of more than 1 m / s leads to a break in the chain link at the attachment point of the float chamber to the connecting unit of the sections and, accordingly, damage to the shell of the float chamber. Replacing a chain traditionally used as a lower power element with a galvanized cable increases the reliability of the fence.

The implementation of the floats in the form of enclosed in a shell (float chamber) rollers made of foamed polyethylene eliminates the failure of the device as a result of possible damage to the shell.

When the length of one section is not more than 10 meters, the weight of the boom is reduced (additional technical result), and the connection of adjacent sections using a quick-disconnect Z-shaped lock connection reduces the time (additional technical result) of the assembly and deployment of the boom on the water.

The fabric shell sections of the utility model are made, as a rule, of PVC material, although it is possible to use any other fabrics resistant to oil and oil products. Technological seams are performed by heat welding.

In special cases of the execution of the fence, the used cables are placed in special pockets of the fabric shell, and lead weights on the lower cable are fixed with bolts.

The essence of the utility model is illustrated by drawings:

- figure 1: boom section;

- figure 2, 3: types of castle joints.

Below, on a specific, but not the only possible example of the design of the BZPP "Barrier-50" design, information is provided that confirms the possibility of implementing a utility model with the achievement of the above technical result.

BZPP consist of separate sections with a length of 10 m each, interconnected by quick locks. The section can conditionally be divided into an upper, above-water part located above the waterline and preventing the oil film from being thrown over the boom, and a lower, underwater part, located below the waterline and preventing the entrainment of oil.

The outer fabric shell 1 of the standard section is made of PVC material, the technological seams of the section are made by heat welding. The table shows the main dimensions and technical data of one section.

In the upper part of the section are hermetically sealed by heat sealing cylindrical floats 2, made in the form of air cavities (float chambers), where the rolls of foamed polyethylene are inserted. Floats provide buoyancy to the boom.

Above the floats, on the upper edge of the section in a special pocket, a galvanized metal cable 3 is laid, which is a power element that removes the load from the action of waves, wind of the currents from the fabric shell of the section, including when towing the boom.

Each float is equipped with a skirt 4 (screen, apron, part of the section web below the float) with ballast in the form of a galvanized cable 5 laid along the lower edge of the section with lead weights 6, ensuring the vertical position of the section when placed on water. Lead load is attached to the lower cable 5 in pairs with three bolts with immersion of the bolt head, the weight of each pair of goods is 2.2 kg. There is a longitudinal groove in the cargo for the cable.

The adjacent boom sections are interconnected (Fig. 2) by a quick-disconnect Z-type ASTM (American Society for Testing and Materials - American international voluntary organization that develops and publishes standards for materials, products, systems and services) with an aluminum lock joint 7, which it is additionally fixed with two retaining fingers 8. When installing booms on rivers with a high flow velocity (more than 1.5 m / s) by means of these fingers, a deflecting wing can be attached to the lock.

When setting up a boom barrier on rivers with high flow rates, it is recommended to use anchor systems to give higher stability and ensure the vertical position of the BZPP.

The warranty period of operation of this BZPP is 12 months. from the date of commissioning, but not more than 36 months. from the date of manufacture.
