Abstract

This invention relates to environmental protection. The purpose of the invention is to increase the efficiency of the device by providing localization of the oil spot and pushing it to the oil receiver. The device includes a two-drum winch 3 installed on ice 2 reservoirs, and the oil receiver 22, lowered under the ice. Two branches of floating boom obstacles 7 are wound on the drums of the winch 3, at the ends of which are fixed shuttles 12 and 13 of ferromagnetic material with loops to connect them with the pin. The boom is passed under the ice and bends around the vertical roller guides 17, 18 fixed in ice along the contour of the oil spot. Electromagnetic washers 16 are located on the ice surface, interacting with shuttles 12 and 13 and providing installation of booms under ice and localization of the oil spot. To ensure that the oil is pushed to the oil receiver 22, the guides 17 and 18 are removed and the booms are wound onto drums with pins connected to the shuttles. At the end of the collection of oil from under the ice pin removed. The device provides efficient collection of oil spills from under ice in open water areas over large areas. 2 Il. J

Description

The invention relates to devices for collecting oil, in particular from the surface of ice-covered water.

The aim of the invention is to improve the efficiency of the device by providing localization of the oil spot and pushing the oil to the oil receiver.

The invention is illustrated in the drawing. Figure 1 shows a longitudinal section of the device; figure 2 is a view in plan.

The oil recovery device consists of a base plate 1 installed by a non-ice pit2. On the plate 1 is placed winch 3 with drums 4, 5, with a drive 6. On

The reels 4, 5 are wound with a boom boom 7 consisting of two elastic blades 8, 9 with float chambers 10, 11, at the ends of which are shuttles 12 and 13, made of magnetic material with loops 14 and pin 15, of two electromagnets 16 , made in the form of washers, vertical roller guides 17, 18, horizontal rollers 19, 20, from a hose 21 to an oil receiver 22 connected to a pump 23 communicated with a storage tank 24. The ice hole of the water body is indicated by the positions 25, 26 27

The device works as follows.

ABOUT

ate yoo yu

The location of the oil spill beneath the ice is marked up, and ice holes 25.26 are executed there, 27. Vertical guides 17.18 are installed in the ice hole. A winch 3 with a drive 6 is installed above the ice-hole 24, with horizontal rollers 19, 20. In the ice-hole 26, the intake 22 is lowered, the hose of which 21 is connected to the pump 23 and the storage tank 24.

Electromagnets 16 are lowered onto the ice surface and are connected to their power source (not shown). The drive 6 of the winch 3 is turned on, rotating the drums 4, 5. At the same time, elastic webs 8, 9 with float chambers 10,

11, on the ends of which are fixed shuttles

12.13, will be unwound, skipped over a horizontal roller 20, onto vertical guides 17, moving from a horizontal position to a vertical one. The electromagnets 16 are brought into position above the shuttles 12, 13 under the ice and turn on and capture the shuttles with their magnetic fields.

When electromagnets 16 move along the ice surface and simultaneously wind the boom 7 from the drums 4, 5 of the winch 3, the shuttles 12, 13 will follow under the ice cover 2 and tow the branches of the boom 7 on each side of the marked area 17, 18. Driving the electromagnets 16 shuttles 12, 13 to the hole 27, their loops 14 are connected and secured with a pin 15. The drive 6 of the winch 3 and the electromagnets 16 are turned off. By briefly turning on the drive 6 of the winch 3, the boom 7 is tensioned on the winding, after which the winch is turned off. The vertical guides 18 are removed from under the ice cover, releasing the boom 7, which, due to the buoyancy of the float chambers 10,11, is floating, pressed against the inner surface of the ice cover 2.

In this arrangement, the device is prepared for the collection of oil located inside the boom-contoured section.

The oil is collected as follows.

The pump 23 is turned on, and the oil is pumped out through the oil receiver 22 through the hose 21 by the pump 23 into the storage tank 24. The drive 6 of the winch 3 is turned on, transmitting the rotation to the drums 4, 5, which will wind the boom 7, pulling it out of the hole 25. 7, freed from vertical

the guides 18 will move under the ice cover 2 to the vertical guides 17, pushing the oil to the ice hole 26 where it is sucked through the oil receiver 22.

When the boom 7 passes through the space from the vertical guides 17 to the horizontal, the roller 20 will rotate from the vertical to the horizontal position, which is finally formed by the horizontal roller 19. The boom 7 is wound onto the drum 4, 5 in

horizontal position.

After the boom has reached the hole in the ice hole 26, the extreme vertical guides 17 are removed from under the ice cover, the pump stops

23, the oil receiver 22 and the hose 21 are removed from the ice hole 26. The booms continue to be wound on the drums 4.5 of the winch 3, until the shuttles 12,13 fit into the ice hole 25. The pin 15 is removed from the loops 14, disconnected the shuttles 12, 13. The remaining portions of the boom 7 are wound on the drums 3, 5 and the winch 3 is stopped by turning off the drive 6. The device moves to

new place of work.

Further operation of the device continues in the order set forth.

Compared to devices of this type, the proposed technical solution provides a more efficient collection of oil by ensuring the localization of oil spots spilled under the ice cover, as well as pushing it to an oil receiver. The proposed device can be used not only for collecting oil, but also for other substances floating under the ice cover.

The use of the device provides environmental protection and economic

advisable in open water.
