Abstract

The invention relates to a device preventing crabs and borers from ascending the stakes in mussel beds. It is frustoconical in shape and is easily fitted with one or two flat-headed nails. The component according to the invention is intended particularly for the protection of mussels.

Description

La présente invention concrrne une pièce technique destinée à empêcher les crabes ( Carcinus Maenas ) et les perceurs (famille des
Muricidées Purpura Nucella Papillus Océnébra) de monter sur les pieux pour moules de Bouchot.The present invention concretes a technical piece intended to prevent crabs (Carcinus Maenas) and piercers (family of
Muricidae Purpura Nucella Papillus Océnébra) to climb on the piles for Bouchot mussels.

Traditionnellement cette protection est effectuée par des bandes de plastique (fig.2) coupées en frange mais qui ne protège les moules que très faiblement car 8 à 12 kg de moules sont mangées par les crabes et perceurs. Traditionally, this protection is carried out by plastic strips (fig. 2) cut into fringes but which protects the mussels only very weakly because 8 to 12 kg of mussels are eaten by crabs and piercers.

Le dispositif (fig.1) selon l'invention permet de remédier à cet inconvénient car de forme tronconique, les perceurs et crabes se heutent à un barrage d'où la protection à 100% des moules de Bouchot. The device (fig. 1) according to the invention overcomes this drawback because of frustoconical shape, the piercers and crabs hoot at a dam hence the 100% protection of Bouchot mussels.

Selon une forme de réalisation, cette pièce est injectée en matière plastique (polyétilène, polystirène, polypropilène, A.B.S., P.V.C.  According to one embodiment, this part is injected in plastic material (polyetilene, polystirene, polypropilene, A.B.S., P.V.C.

polycarbonate) en une seule opération de moulage par injection.polycarbonate) in a single injection molding operation.

La figure I représente en coupe la forme de la pèce tronconique. Figure I shows in section the shape of the frustoconical part.

La figure 2 représente ce qui existe actuellement. Figure 2 shows what currently exists.

La forme de la pièce représentée par la figure 1 représente us entonnoir, ayant les dimensions approximative suivantes:Hauteur du tronc(1) 75mm, diamètre du tronc(2) 15vmm,hauteur du cne(3)l7Omm, diamètre du cône(4)260mm.  The shape of the part shown in Figure 1 represents us funnel, having the following approximate dimensions: Height of the trunk (1) 75mm, diameter of the trunk (2) 15vmm, height of the cone (3) l7Omm, diameter of the cone (4) 260mm.

La pièce est fixée sur les pieux par un ou deux doux à tête plate. La pièce selon l'invention est particulièrement destinée à la protection des moules de Bouchot. The part is fixed on the piles by one or two soft with flat head. The part according to the invention is particularly intended for the protection of Bouchot mussels.

De plus le dispositif selon l'invention est souple et résistant aux intempéries et marées, supportant le poids des vagues et algues, celui-ci se déformant apr ces efforts mécaniques. In addition, the device according to the invention is flexible and resistant to bad weather and tides, supporting the weight of waves and algae, the latter being deformed after these mechanical forces.

Le dispositif est conçu pour que la pièce reprenne à tout instant sa forme initiale de protection. The device is designed so that the part resumes its initial form of protection at all times.

Le dispositif présente en outre une paroi lisse destinée à empe- cher toute accroche des particules et autres.  The device also has a smooth wall intended to prevent any attachment of particles and the like.
