Description
Technical field
The invention belongs to sports equipment technical fields, and in particular to a kind of anti-suction people's structure of swimming pool draining.
Background technique
Swimming pool is the place that people are engaged in swimming exercise, and people can be movable inside or play.For example, in inflammation
In the summer of heat, swimming pool is that children's favorite likes one of place played.However while people swim and play,
Under cover many safety problems.For example, " swimming pool the inhales people " accident to happen occasionally in recent years, reason are:In swimming pool
Water circulation system is installed, which is arranged swimming pool discharge outlet in bottom of pond, and bottom of pond draining can generate very strong negative pressure, and being easy will
People is drawn to drainage pipeline, and so as to cause the generation for accidentally inhaling safety accident, especially child is even more difficult to save oneself because suction is big.By
This security risk caused by the swimming-pool water circulatory system seriously threatens the life security of swimmer, while also seriously affecting
Swim this movement for body-building and leisure carry out in a deep going way.
In order to solve the shortcomings of the prior art, people have carried out long-term exploration, propose miscellaneous solution
Scheme.For example, Chinese patent literature discloses a kind of anti-suction people device [application number of swimming pool water return outlet:
201620272278.9], including be arranged in vacuum detecting mechanism at water return outlet, air hole valve and the control back water pump,
The master controller of vacuum detecting mechanism, air hole valve sum;The back water pump is arranged in close in the water return pipeline
Swimming pool bottom;The air hole valve is arranged by the water return outlet and original state is to close.
Above scheme solves the problems, such as that easily people is sucked for existing swimming pool water return outlet to a certain extent, but the program
The release of water return outlet suction is mainly realized by detection water return outlet vacuum degree, sensitivity is poor, and it is stranded to be easy to happen human body
But the phenomenon that water return outlet is not completely plugged, bad adaptability can not be suitable for common swimming pool.
Summary of the invention
