Swimming pool drain stepping self-closing structure

Abstract

The invention relates to a tread type self-enclosed structure of a swimming pool outfall. The tread type self-enclosed structure of the swimming pool outfall solves the technical problem that the safety is poor when an existing swimming pool draining away water. The tread type self-enclosed structure of the swimming pool outfall comprises an outfall, a circular groove, an integrated water-stop capsule body, outside circular capsule bodies, inside capsule bodies and a telescopic support connecting rod, wherein an outside tread area and an inside tread area arranged annularly are correspondinglyarranged on the periphery of the circumference direction of the outfall in sequence, and shape changing capsule bodies are arranged in the outside tread area and the inside tread area. The outside circular capsule bodies correspondingly communicate with the shape changing capsule body of the outside tread area through a first one-way communication assembly, and the inside capsule bodies correspondingly communicate with the shape changing capsule body of the inside tread area through a second one-way communication assembly. The tread type self-enclosed structure of the swimming pool outfall has the advantages that the shape changing capsule bodies generate shape changing when feet tread on a pedal when someone closes to the outfall, at the same time, inner gas or fluid is conveyed into theintegrated water-stop capsule body to enable the integrated water-stop capsule body to bulge to slow down the water discharge or close directly the outfall, and the occurrence of an aspiration safetyaccident can be avoided.

Description

technical field [0001] The invention relates to the technical field of swimming pools, in particular to a stepping-type self-sealing structure for a swimming pool drain. 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 sport of sw...

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.
