Abstract

An automatic cut-out switch, especially for use in a swimming pool recycling/filtering circuit, consists of an inverted T-shaped PVC housing situated above a pumping unit and through which the water passes between an inlet (3) and an outlet (4). The vertical section of the housing contains a float (9) equipped with a permanent magnet to actuated a flexible blade switch situated on a cover which closes the vertical section. In the event of an interruption in the flow through the housing, e.g. due to a drowning person blocking the suction outlet in the swimming pool, the float drops and the magnet actuates the switch to shut off the pump via a low tension relay.

Description

La présente invention concerne un dispositif de coupure instantanée de l'alimentation électrique des moteurs de pompes, notannnent ceux de recyclage des eaux de piscines. L'interruption de cette alimentation, en cas de danger, s'effectue manuellement. Hors, le manque de rapidité de cette interruption est souvent dramatique. Accidents par noyades dans les piscines publiques et privées par obturation de la bonde de fond. (17)
Le dispositif selon l'm vention permet de remédier à ce risque.The present invention relates to a device for instantaneous cut-off of the electrical supply to the pump motors, in particular those for recycling swimming pool water. The interruption of this supply, in the event of danger, is carried out manually. However, the lack of speed of this interruption is often dramatic. Accidents by drowning in public and private swimming pools by closing the bottom drain. (17)
The device according to the invention makes it possible to remedy this risk.

I1 comporte en effet, selon une première caractéristique, un équipage mobile constitué d'un aimant permanent encapsulé dans un flotteur oscillant sur un axe à l'intérieur d'un boîtier PVC en forme de T à incorporer sur la canalisation d'aspiration d'un système de pompage. I1 in fact comprises, according to a first characteristic, a movable assembly consisting of a permanent magnet encapsulated in a float oscillating on an axis inside a T-shaped PVC casing to be incorporated on the suction pipe of a pumping system.

Avec le flotteur s'élève ou s'abaisse l'aimant permanent de sollicitation du contact d'un interrupteur à lame souple situé extérieurement et connecté à une source de courant basse tension qui assure par 1 'intermédiaire d'un relais l'alimentation électrique de la pompe. With the float, the permanent magnet for soliciting the contact of a switch with a flexible blade located externally and connected to a low voltage current source which supplies the electrical supply by means of a relay is raised or lowered. of the pump.

Le dispositif fonctionne suivant un principe physique : plein ou vide dû au passage dynamique, statique ou absence de fluide liquide. Si la bonde de fond est obstruée par une personne en cours de noyade, l'équipage mobile bascule sur son axe dès l'absence de fluide et coupe la commutation de l'interrupteur à lame souple. The device works according to a physical principle: full or empty due to dynamic, static passage or absence of liquid fluid. If the bottom drain is obstructed by a person in the process of drowning, the moving equipment switches on its axis as soon as there is no fluid and cuts off the switching of the flexible blade switch.

Les dessins annexes illustrent l'invention :
La figure (1) représente en coupe le dispositif de l'invention.The accompanying drawings illustrate the invention:
Figure (1) shows in section the device of the invention.

La figure (2) représente le flotteur (9), le corps (1) du boîtier en forme de T intégrant le tube capillaire (16) l'écrou (8) le tampon (7} En référence à ces dessms du boîtier en forme de T, la figure (3) représente un schéma d f inplantatation du dispositf d'arrêt sur la canalisation d'asplration dans laquelle circule le fluide liquide (2).  Figure (2) shows the float (9), the body (1) of the T-shaped housing integrating the capillary tube (16) the nut (8) the buffer (7} With reference to these dessms of the shaped housing of T, FIG. (3) represents a diagram of implantation of the stop device on the suction pipe in which the liquid fluid (2) circulates.

L'orifice vertical (5) du boîtier (1) dans lequel navigue l'équipage mobile oscillant (6) est mis en dépression par l'intermédiaire d'un tube capillaire (16) débouchant dans l'orifice (4). The vertical orifice (5) of the housing (1) in which the oscillating moving element (6) navigates is placed under vacuum by means of a capillary tube (16) opening into the orifice (4).

La face supérieure du flotteur(9) intègre le palier (14) de l'axe (10) et l'aimant (11) de sollicitation de l'interrupteur à lame souple (12) connecté en basse tension. The upper face of the float (9) integrates the bearing (14) of the axis (10) and the magnet (11) for biasing the flexible blade switch (12) connected at low voltage.

Le bottier PVC en forme de T est relié à la canalisation d'aspiration par les orifices horizontaux (3) et (4) en amont de la source de pompage (13) qui transite le fuide liquide (2). The T-shaped PVC casing is connected to the suction pipe by the horizontal orifices (3) and (4) upstream of the pumping source (13) which transits the liquid fluid (2).

L'orifice verticaL (5) dans lequel est installé l'équipage mobile oscillant (6) est obturé par un tampon (7) intégrant l'interrupteur à lame souple (12) scellé extérieurement en un point précis de sollicitation par l'aimant du flotteur (11). Ce tampon coopère avec l'écrou (8) d'assemblage sur le boîtier (1) et le joint (15) d'étanchéité. The vertical opening (5) in which the oscillating moving element (6) is installed is closed by a buffer (7) integrating the flexible blade switch (12) sealed externally at a precise point of stress by the magnet of the float (11). This pad cooperates with the nut (8) for assembly on the housing (1) and the seal (15).

En cas d'obstruction, la remise en marche de l'alimentation électrique de la pompe (13) s'effectue manuellement par action sur le relais de commutation basse tension. In the event of an obstruction, the power supply to the pump (13) is restarted manually by action on the low voltage switching relay.

Le dispositif selon l'invention peut s'appliquer à la sécurité des installations de puisage dans le cas d'un iSnque d'eau.  The device according to the invention can be applied to the safety of drawing-off installations in the case of a water supply.
