Automatic drainage mechanism for floor drains and trap boxes

Abstract

An automatic drainage mechanism for floor drains and trap boxes, which is equipped with a grid, a protection ring that surrounds the edge of a core helping to seal and blocking the return of odors and insects, an upper support, a set of magnets, a lower support, a retaining grid that helps block the passage of small animals and a base. Thus, the drainage mechanism, by means of the upper support with the set of magnets and with the lower support create the spring effect in the core, since the set of magnets is divided into arranged on the upper support and arranged on the lower support, in which the magnets are arranged in opposite ways, but with the same polarities facing each other, generating a repulsion between the upper and lower supports.

1 . An automatic drainage mechanism for floor drains and trap boxes, in which the drainage mechanism is provided with a grid, a core, a set of magnets, a lower support and a base, characterized by the drainage mechanism comprising an upper support being configured by a first edge, at least two first beams that project from the inner face of the first edge towards the geometric center of the upper support in which a guide pin is arranged; the first edge comprising at least one guide projection and each first beam comprising at least one first housing for magnets and set of magnets; the lower support being configured by a second edge, at least two second beams that project from the inner face of the second edge towards the geometric center of the lower support, in which a guide hole is arranged to receive the guide pin of the upper support; the second edge comprising at least one guide channel to receive the guide projection of the first edge of the upper support; each second beam comprising at least one second housing for magnets and set of magnets. 
     
     
         2 . The automatic drainage mechanism for floor drains and trap boxes, according to  claim 1 , characterized by the core being surrounded, at the edge thereof, by a protective ring; each first beam comprising a first through-hole for maintenance, which is arranged over each first housing; each first beam comprising a stopper of the core; the first edge comprising at least one stroke limiter) and at least one locking projection of the core; each second beam comprising a structural rib and a second through-hole for maintenance, which is arranged over each second housing; the drainage mechanism comprising a retaining grid for blocking the passage of small animals.
