Abstract

A float (1) is mounted in a metal shaft (2) which supports, at its base, a weight (3). The shaft is supported via two guides which permits free movement of the shaft. The assembly is fitted to a pipe by a semicircular coupler (6) which is clamped onto a flat metal plate (4) which allows the shaft to run up its side. The top of the shaft is connected via a mobile joint to a pointer which is pivoted a small way along a needle fixed to the coupler. The pointer is positioned against a card so that its movement can be readily observed. When the pipe is full it will be at a different position with respect to the float than when it is not full. ADVANTAGE - Replaces pressure gauges and their attendant pipes and mountings.

Description

JAUGE DE CHARGE POUR MATERIAUX
TANSPORTES DANS L'EAU PAR TUYAUX FLOTTANTS
La présente invention concerne un dispositif pour contrôler la charge transportée par le tuyau de refoulement d'une drague suceuse en exploitation sur l'eau.LOAD GAUGE FOR MATERIALS
TANSPORT IN WATER BY FLOATING PIPES
The present invention relates to a device for controlling the load transported by the delivery pipe of a suction dredge in operation on water.

Le contrôle de charge est traditionnellement effectué à l'aide de manomètres de pression (1 ou plusieurs) ayant leur pri- se sur le tuyau de refoulement. Ce dispositif présente l'inconvé-nient d'être mis en défaut d'une part, par l'obstruction du tuyau d'aspiration lors d'éboulements sous l'eau et d'autre part, par obstruction des conduits assurant la bonne marche des manomètres ceux-ci se chargeant de boues et sables. The load control is traditionally carried out using pressure gauges (1 or more) having their grip on the discharge pipe. This device has the disadvantage of being faulty on the one hand, by the obstruction of the suction pipe during landslides underwater and on the other hand, by obstruction of the conduits ensuring proper functioning manometers, these being loaded with mud and sands.

Le dispositif selon l'invention permet de remédier à'ces inconvénients. Le principe de base résulte d'une constatation visuelle et physique. Sous l'effet de la charge, circulant dans le tuyau de refoulement, reliant la drague en exploitation sur le plan d'eau et le bassin de stockage de matériaux, les flotteurs maintenant le tuyau de refoulement au-dessus de l'eau,.s'enfon- cent de façon plus ou moins importante, ce phénomène, application intrinsèque du principe d'Archimède (tout corps placé dans l'eau subit une poussée égale au poids du-volume d'eau déplacé) presentait l'inconvénient de ne pas être suffisamment important pour être utilisé de façon qualitative.L'astuce residait donc dans l'amplification du mouvement en translation, en mouvement de rotation par un dispositif (fléau pointeau). The device according to the invention overcomes these drawbacks. The basic principle results from a visual and physical observation. Under the effect of the load, circulating in the discharge pipe, connecting the dredge in operation on the water body and the material storage basin, the floats holding the discharge pipe above the water. sinking more or less, this phenomenon, intrinsic application of the principle of Archimedes (any body placed in water undergoes a thrust equal to the weight of the volume of water displaced) had the disadvantage of not not be important enough to be used qualitatively.The trick therefore resided in the amplification of the movement in translation, in rotation movement by a device (needle flail).

Le dispositif selon l'invention se compose d'un flotteur (1) monté sur une tige métallique (2) dont la longueur varie selon le type et l'installation de la drague. La tige supporte à sa base, sous le flotteur, un poids (3) qui sert au tarage du dispositif. Un support (4) (dans le plan vertical sur le dessin derrière la tige) sur lequel sont fixés deux guides (5) qui permet tent la libre translation de la tige (2). Une bride (6) assure la fixation au dispositif sur le tuyau de refoulement de la drague suceuse. Un fléau (7) fixe au sommet delta tige (2) par une liaison mobile (8) permet de transformer par l'intermédiaire d'un pointeau (9) fixé sur la bride (6) le mouvement de translation en rotation et d'amplifier le mouvement. Le mouvement du fléau est visualisé sur un panneau (10) étalonné. Le point 0 déterminé quand le tuyau est plein d'eau des qu'il passe des matériaux dans le tuyau la charge augmente et le fléau descend. Dans les cas de mauvaise visibilité du panneau un appareillage électrique transforme et transmet les mouvements de l'appareil sur un cadran dans la cabine de l'opérateur. Le dispositif selon l'invention est particulièrement destiné à contrôler la charge d'un matériau transporté par le tuyau de refoulement d'une drague suceuse à refoulement flottant.  The device according to the invention consists of a float (1) mounted on a metal rod (2) whose length varies according to the type and installation of the dredge. The rod supports at its base, under the float, a weight (3) which is used to calibrate the device. A support (4) (in the vertical plane in the drawing behind the rod) on which are fixed two guides (5) which allow the free translation of the rod (2). A flange (6) secures the device to the suction pipe of the suction dredger. A beam (7) fixed at the top of the rod (2) by a mobile link (8) makes it possible to transform, via a needle (9) fixed on the flange (6), the movement of translational rotation and amplify the movement. The movement of the beam is displayed on a calibrated panel (10). The point 0 determined when the pipe is full of water as soon as materials pass through the pipe, the load increases and the beam descends. In the event of poor visibility of the panel, electrical equipment transforms and transmits the movements of the device on a dial in the operator's cabin. The device according to the invention is particularly intended for controlling the load of a material transported by the delivery pipe of a suction suction dredge with floating delivery.
