Treading self-sealed type swimming pool drainage suction prevention structure

Abstract

The invention relates to a treading self-sealed type swimming pool drainage suction prevention structure which solves the technical problem that an existing swimming pool is poor in safety during drainage. The treading self-sealed type swimming pool drainage suction prevention structure comprises a drainage opening, a drainage pipeline, a water inlet, a water outlet, a manual water valve, treadingareas, a mounting groove, a waterproof type movable mounting structure, treading plated, deformation capsules and a conjoined water blocking capsule. The conjoined water blocking capsule extends inwards along the circumferential inner side of the drainage opening, a telescopic supporting connection rod is arranged on the lower side of the conjoined water blocking capsule, and different inner cavities of the conjoined water blocking capsule communicate with deformation capsules located in the different treading areas in a one-way mode. The treading self-sealed type swimming pool drainage suction prevention structure has the advantages that when people approach to the drainage opening and tread the treading plated, the deformation capsules deform and meanwhile gas or liquid in the deformation capsules is conveyed into the conjoined water blocking capsule, so that the conjoined water blocking capsule bulges to decrease the water discharging amount or directly close the drainage opening,mistaken suction accidents can be avoided, and the personal safety of a swimmer can be effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of swimming pools, in particular to a stepping self-enclosing swimming pool drainage and anti-suction structure. Background technique [0002] A swimming pool is a place where people engage in swimming, where people can move or compete. For example, in the hot summer, the swimming pool is one of the children's favorite places to play. However, when people swim and play, many safety problems are hidden. For example, in recent years, there have been accidents of "swimming pool sucking people". The reason is that a water circulation system is installed in the swimming pool. Suction to the drain pipe, resulting in aspiration accidents, especially for children, because of the strong suction, it is difficult to save themselves. This potential safety hazard caused by the swimming pool water circulation system seriously threatens the life safety of swimmers, and also seriously affects the deep development of the ...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned scheme solves the problem that the existing swimming pool backwater is easy to attract people to a certain extent, but this scheme mainly realizes the release of the suction of the backwater by detecting the vacuum degree of the backwater, and needs to rely on vacuum detection equipment. When the vacuum detection equipment When the detection accuracy is low or when a fault occurs, it is easy to cause the human body to be trapped but the water return port is not completely blocked. The adaptability is poor and it cannot be applied to ordinary swimming pools.
