Description

one

The invention relates to shipbuilding, in particular, to devices designed to catch oil products from salient waters.

Oil-harvesting devices for catching oil products from the surface of polluted water areas are known, which contain a receiver: oil and a trap and are attached to the vessel with the possibility of controlling their depth.

The purpose of the invention is to increase the efficiency of oil recovery and to ensure the automatic maintenance of the trawl at a given depth in any mode of the treated surface of the water area.

This is achieved by the fact that, in the proposed device, the trap is made in the form of two conical nozzles fixed on the oil receiver, between which the chamber of immersion sensors is located, connected to the trawl depth regulator, and the trap cavity is covered by a protective net. In front of the oil receiver, there is a mesh surge suppressor connected to the receiver in the lower part by means of a system of adjustable brackets, and in the upper part - with the edge of the conical nozzles by adjustable struts, so that the surge suppressor can be installed at any angle to the surface of the aquatory. The tops of the conical nozzles of the trap are connected to the receiving pipelines of the oil recovery system of the ship, where the oil is separated from the water by special AND devices.

FIG. 1 shows a schematic view of the described oil intake trawl, top view; ia fit. 2 is a section along A-A in FIG. one; in FIG. 3-section along BB in FIG. one;

The oil trawl consists of oil receiver 1 smoothly transferring into a tongue 2, behind which shutter 3 is located, and trap 4. Trap 4 ends up with two symmetrically located conical nozzles 5, to the tops of which 6 flexible hoses 7 are connected, connecting them with oil-intake devices the vessel.

The tops 8, welded to the top of the trap 4, are connected to the actuating device for the trawl dredging on the vessel. Between the conical nozzles of the b trap 4 in the center there is a chamber 9 of the immersion depth of the wedge-shaped trawl, and crackers 10 are attached to its ends, with the help of which

the trawl is moved between the hulls of the catamaran vessel along rails. The cavity of the trap 4 is closed by a protective grid M, behind which is a perforated pipe 12. In front of the trap 4, using a system of adjustable brackets 13 and 14, as well as adjustable straps 15, there is a mesh surge suppressor 16, which is an S-shaped sheet. The sensor chamber 9 is divided by a waterproof wall 17, in which — one above the other — sensors 18 for depth and pressure, are associated with trawl depth regulators. The front part of chamber 9 is deaf and is a vertical broken knife 19, which cuts symmetrically the iHOTOiK mixture IB of the trawl into two equal parts. Inside the front of chamber 9, there is located the additional 20, in which a nozzle 21 with a specific hydraulic resistance is mounted, connecting the front part of chamber 9 with the treated medium through a soothing tank 22 protected by a mesh 23. The upper part of chamber 9 is connected to the atmosphere by a vent pipe 24 .

During operation of the oil intake trawl, oil 1 is buried automatically by a certain amount using the immersion depth sensors associated with the actuator. The mesh surge suppressor 16 is installed at a certain height relative to the oil receiver 1 with adjustable brackets 13 and 14 and adjustable braces 15, and its inclination is chosen depending on the state of the water surface of the water area. Under the action of the velocity head of oil contamination, water flows through the oil receiver 1, the tongue 2 enters the trap 4 and is blocked by the gate S. The flow in the trap 4 is divided into two equal parts along the conic nozzles 5 and the flexible receptacles hoses 7 are supplied to the oil collecting systems of the vessel. The mixture entering the trap 4, the passage through the protective grid AND, is cleared of debris and dirt with the help of compressed air or pressurized water supplied from the systems of the ship to the perforated pipe 12; the protective net 11 is periodically cleaned of debris and dirt. The chamber 9 is connected to the atmosphere by a pipe 24, and a pressure-reducing vessel 22, protected from contamination by a net 23, and a nozzle 21, built in to the bottom 20, with a certain hydraulic resistance ensuring smooth start-up with the treated water area.

by means of sensors .18 of the depth of the actuator of the system on the descent or (the rise of the trawl without jerks taking into account the wave. These structural elements are sensitive to changes in the vessel’s draft and hydrostatic

pressure of the liquid column on the wave, but not sensitive to an instantaneous random change in the hydrostatic liquid column of the treated surface of the water area.

Subject invention

The oil trawl containing the oil receiver and the trap mounted on the vessel with the ability to control its depth, characterized in that, in order to improve the efficiency of oil collection and provide automatic maintenance of the trawl at a given depth, the trap is made in the form of two conical nozzles attached to the oil receiver between which is placed

the chamber of immersion depth sensors associated with the trawl depth controller, with the trap cavity closed by a protective net, in front of the oil receiver is installed a mesh surge suppressor connected to the receiver in

the lower part through the system of adjustable brackets, and in the upper part - with the edge of the conical nozzles by means of adjustable straps, while the tops of the conical nozzles of the trap are connected to each other
