FR2816969A1 - Floating modular barrage has rigid tubular construction with male and female end couplings and lugs for fastening skirt - Google Patents

Abstract

The barrage is made from a series of rigid sealed and buoyant tubular modules with male and female end couplings for joining a series of modules together. Each module has two orifices with sealed caps for optional filling, and the end couplings are in the form of two or three projections which slot together and are fastened by a rod inserted through holes in the projections. The underside of each module has lugs for fastening a rigid security skirt along at least part of the barrage.

Description

<Desc / Clms Page number 1>

 The present invention relates to a floating device making it possible to deflect any floating object or material on the surface of a liquid in order to protect a structure or a site while ensuring maximum reliability of the device itself as well as a space requirement and a minimum weight facilitating transport, installation, repair and mobility of the whole.

 The versatility of the device also allows the construction of a floating assembly composed of a minimum of four interconnected elements forming a very stable floating support that can be used as decking or fish tank etc ...

 The prior techniques being carried out by systems of large bulk, of a very high weight requiring the use of important material that it is for the transport, the installation, the repair, the mechanical reliability and the rapid re-use of the systems.

 The device according to the invention makes it possible to remedy all these drawbacks on account of the meticulous and practical study of the smallest detail of construction.

 The device being made of polyethylene in order to benefit from the following advantages: - acceptance of significant rage.

 - no corrosion problem.

 - no pneumatic deformation.

 - UV stability.

 - stability to hydrocarbons.

 - possibility of colors.

 - positive buoyancy of polyethylene.

 The device consists of modular elements linked together by a profiled male / female articulation system, held by an oversized rod (2) in order to increase the friction surfaces due to the horizontal and vertical movements (less stressed) as well as the resistance of each element of the device.

 Each cylindrical element (1) makes it possible to dissuade the possible circulation on the device put in place as well as to endow any sharp angle which can cause a blocking of object or offering a point of wear therefore of weakness.

 Each float joint of profiled and rounded shape can accept a maximum angle of 90.

 Each element fitted in the lower part with five tabs provided with a bore (4) allows the fixing of a protective skirt (5) and the ballasting.

 Each element equipped with two plugs (3) allowing access to the interior volume and the possibility of fixing a safety cable by eye bolt.

 The dimensions of an element allow easy storage and transport is facilitated.

 Each modular element is provided with two orifices allowing a possible filling of the element, closable by hermetic plugs (3), positioned on the same longitudinal axis in the upper part.

 Each plug (3) closing one of the orifices can accommodate a screwed stainless steel peg.

 The oversized connecting rods in the shape of a "T" (2) are stopped in the lower part by a washer and a retaining screw in order to guarantee the holding of the assembly and to dissuade any harmful player.

The accompanying drawings illustrate the invention:
Figure 1: shows in section, one of the element of the invention.

 Figure 2: shows in section, the device in place with these two options (5) (6).

 Figure 3: shows the mooring system of the device at its two ends.

 With reference to this drawing, the device comprising several identical elements composed of a molded body (1) one end of which is provided with a female part and the other with a male part.

 The female interlocking end consists of three extensions of the rigid planar structure, each provided with an orifice placed on a common axis allowing the introduction of a securing rod (2), the male interlocking end consisting of two extensions of the rigid planar structure, each provided with an orifice placed on a common axis allowing the passage of the securing rod.

 The mooring system in Figure 3, which can undergo much greater mechanical stresses, is made of anticorrosive materials of the aluminum or stainless steel style.

 The two yokes in Figure 3 in the shape of a "U", the two parallel dishes of which are each provided with an orifice placed on a common axis allowing the introduction of a fixing rod in the shape of a "T".

 The clevis of the mooring system in Figure 3 made from the male end of an element is similar to the clevis used on the female part.
