FR2851268A1 - Floating barrier for stopping pollution e.g. algae pollution, in sea water, has polypropylene band perpendicularly riveted to polyvinyl chloride tubes including fence below whole length of tubes - Google Patents

Abstract

The device has vertical round poly vinyl chloride (PVC) tubes (1) of diameter 32 millimeter and height 2 meters. A polypropylene band (2) of 70 centimeter X 1 millimeter perpendicularly riveted on the tubes. A fence (3) of height 1.2 meters is provided below the whole length of the tubes. The assembly of tubes is supported by three floaters (4) and is held vertically by a ballast (6) at the base of each tube.

Description

Floating dam to stop all pollution

  The present invention relates to a floating dam intended to stop at sea or in fresh water, any pollution (oil spill, green tide, etc.) the dams existing to date, are heavy, and very long to implement, This dam is made of vertical pvc tubes, (1) diameter: 32mm every 1 ml; these tubes measure approximately 2 m high, and are held together by a strip of P.P. (polypropylene) cm in height, thickness: 1 mm (2) riveted 15 perpendicularly, over the entire length of the dam. advantages of P.P. resistance to hydrocarbons at U V, positive buoyancy Below this strip, is riveted on the tubes, a strip of plastic mesh, (3) 1 m 20 high, also, over the entire length of the dam.

  The purpose of this grating is to stop the floating fuel pellets between two waters. 25 The dam is made up of elements 21 m long each supported by three 6 m by 20 cm wide floats (4) Construction of the 25 mm X 200 mm floating foam floats (12) bonded to a sheet of expanded polystyrene 4 mm thick (9). On the inside of the float, an additional strip of foam is glued, thickness: 25 mm x 5 cm (11). On the outside of the float is riveted an aluminum square 30mmX30mmx 6 mi forming a stiffener (15). The 5 floats are attached to each tube, by a metal bracket (10) fixed to the P.E.

  To hang these brackets, a "Jen alu (7) 7cm high is riveted on the sides of the tube. These floats are easily removable for storage, thanks to small locks (8) fixed on the side dup" é, which prevent the square to come out of its housing.

  This assembly is held vertical, thanks to 15 weights, consisting of chains (6), hooked to the base of each tube. These weights are removable to be able to roll up the dam for storage.

  An element of 21 m consists of a part 20 of lm, without float, followed by 6 m with float, and this, renewed 3 times, to arrive at 21 m. The part of 1 m without float, allows to fold the whole. The parts without float, include a removable stiffener (5), by removing them, the 21 m element is transformed into an 18 m element to create a passage for boat between two elements.

  The elements are assembled together, by easily removable junctions. These junctions are composed in high parts, of studs (13) crossed by an easily removable pin, and at the base, by a metal part (14) specially designed to assemble the two tubes.

  Note for convenience, the elements can measure 49 ml, but can still be folded every 6 ml The height of the float is calculated to allow the dam to protrude, 40 cm above the water surface, but can very be modified during production, according to demand.

  The advantage, too, is that the sets can be launched and folded up for storage from the beach.

Claims (12)

  1) Device for stopping any pollution (sea tide, green tide) at sea or in fresh water, characterized by an assembly of vertical round tubes (1) with a diameter of 32 mm and a height: 2 m arranged every 1 ml, on which is riveted perpendicularly, a strip of PP of 70 cm x 10 1 mm and also below, a mesh of lm2O high (3) over the entire length of the assembly. This assembly is supported by 3 floats (4) and held vertical by weights (6) at the base of each tube.   2) Device according to claim 1 characterized in that the vertical tubes (1) are made of round PVC of 32mm and measure 2 m 3) Device according to claim 1 characterized in that the tubes are assembled by a strip of P.P. 700 mm x 1 mm (2) riveted on the tubes in the upper part, over the entire length of the device.   4) Device according to claim 1, characterized in that a strip of plastic mesh lm20 high (3) is riveted on the tubes in the lower part, over the entire length of the device.   5) Device according to claim 1 characterized in that the device is held in the flotation state, by 3 floats (4) of 6m x 20 cm 6) Device according to claim 5 characterized in that the floats are composed of a foam (12) of thickness: 25mm bonded to the interior, is bonded a second layer of foam 25 mm x 50 mm (11).   7) Device according to claim 6 characterized in that the rigidity of the float is obtained by a 30x30 mm aluminum square (15) riveted to the outer edge of the P.E.   8) Device according to claim 5 characterized in that the floats are hung perpendicular to the tubes, by metal brackets 10 (10) fixed to the floats.   9) Device according to claim 2 characterized in that a 'U "aluminum, 7 cm high (7), is riveted to each tube, to hang the floats, ce'U" also includes on the side, a small 15 latch (8) to prevent the float bracket from coming out of its housing.   10) Device according to claim 1 characterized in that the device consists of a part of 1 m without float followed by 6 m 20 with float and this renewed 3 times for an element of 21 m or 7 times to make an element of 49 m.   11) Device according to claim 8 characterized in that the part of lm without float, 25 allows to fold the whole. This part is held taut, by a removable stiffener (5). By removing this stiffener, you can reduce the length of the assembly, to let a boat pass.   12) bispositif according to claim 1 30 characterized in that the tubes which are at the junction of two elements, are assembled by a stud, and pin, (13) in the upper part, and by a metal part in the lower part (14) .
