Description

FIELD OF THE INVENTION

The invention relates to the protection of the environment and is intended to collect oil spills and oil products under the ice cover of flowing water bodies.

State of the art

A device for the localization of an oil slick from a water surface from under the ice (1. Idrisov R.Kh., Vekilov E.Kh., Niyazov R.S. Bon boom. USSR author's certificate No. 1807166, 1993), which consists of chambers filled with air, united by a common cloth with an apron, attached to it by a sleeve filled with air and distributed weighting materials, cable suspension of the cloth, hoses, pump and compressor.

The disadvantages of this device include the low efficiency of collecting oil and oil products, due to the discreteness of contacting the plate with the surface of the ice cover, the possibility of oil flow through ridges formed by inflatable chambers, as well as the long period of preparatory work associated with the need to make two ice holes of considerable length in the ice cover.

The closest in essence to the claimed invention is a device for collecting oil and oil products from a water surface under ice cover (2. Truskov PA, Samoilov BV Device for collecting oil and oil products from a water surface under ice cover. Patent No. 2166583 Published: 05/10/2001). The device comprises a panel immersed beneath the ice cover with a sleeve filled with air attached to it and distributed weighting materials, a pump, compressor, hoses, a cable rope suspension and a hollow metal rod having neutral buoyancy in water. The sheet is made of absorbent oil and oil products of a hydrophobic material that can acquire a flat shape due to the free folding of the sheet in a horizontal position and having a density lower than the density of the water, which is equipped with a sleeve filled with water. Both air and water filled hoses and distributed weighting agents are located along the contour of the panel. The weights are made with the possibility of ensuring, in the absence of filling the hoses, respectively, with air and water, close to the neutral buoyancy of the assembly, and when filling the hoses, respectively, with air and water, the positive buoyancy of the assembly.

The disadvantage of this invention is the collection of oil and petroleum products from a fixed location.

Disclosure of invention

The objective of the present invention is the collection of oil and oil products from under the ice in bodies of water with a flowing stream.

The technical result achieved in solving the problem lies in the collection of oil under ice over large areas and the reduction of oil spill collection time.

The essential features characterizing the invention

Restrictive: the collection of oil and oil products with a sorbent panel located in a horizontal position under the ice.

Distinctive: a strip of material bearing the function of a water sail is attached to the oil adsorbent placed in a mesh cover with floats.

The implementation of the invention

This goal is achieved by the fact that a strip of material with a load distributed along the bottom is attached to the sorbing material for oil collection, placed in a flexible mesh shell with floats, carrying the function of a water sail, which allows catching and absorbing a stain of oil carried away by the flow from extended areas with downstream spill site.

The sorbent element can be made of the material "Ecosorb" (TU 8397-230-00302327-01).

Brief Description of the Drawing

The drawing shows a General view of a device that allows you to collect oil and oil products under ice 1 and contains a flexible mesh shell 2, which is placed oil sorbent 3 with floats 4. A strip of material 5 with a load 6 distributed along the bottom is attached to the edge of the shell.

The device operates as follows

In the event of an emergency, a device having a sorbent cloth with a water sail, through a lane at the site of an emergency spill, falls under the ice and straightens. With the expansion of the strip 5 under the influence of loads 6 goes down and begins to perform the function of a water sail. The speed of the oil slick adjacent to the bottom surface of the ice due to friction is lower than the speed of the water flow in the river. Therefore, a device lowered under ice begins to collect oil both in the place of an emergency spill, and after passing through a spot, it can catch and absorb it thanks to a water sail. The speed of the device under the ice is regulated by the height of the strip 5 and can be pre-determined based on the speed of the water flow. The device is removed from under the ice by hooks located in the lanes downstream.

Thus, the device allows for a short time to eliminate the consequences of accidental oil spills in the winter under the ice of flowing reservoirs, preventing a large spread of oil spills from the accident site.

Claims (1)
