Description
Technical Field
The invention relates to the technical field of swimming pools, in particular to a treading self-sealing type swimming pool drainage anti-suction structure.
Background
Swimming pools are places where people engage in swimming sports, and people can move or play games inside. For example, in hot summer, swimming pools are one of the favorite playgrounds of children. However, many safety problems are hidden while people play swimming. For example, in recent years there have been "swimming pool suck" accidents occurring because: a water circulation system is arranged in the swimming pool, a swimming pool water outlet is arranged at the bottom of the swimming pool, strong negative pressure can be generated when water is drained from the bottom of the swimming pool, people are easily sucked to the water drainage pipeline, and therefore safety accidents are caused by mistake suction, and especially children are difficult to save themselves due to large suction force. The potential safety hazard caused by the water circulation system of the swimming pool seriously threatens the life safety of the swimmers and also seriously influences the deep development of the swimming sport for fitness and leisure.
In order to solve the defects of the prior art, people have long searched for and put forward various solutions. For example, chinese patent document discloses a device for preventing people from being sucked at a return port of a swimming pool [ application No.: 201620272278.9], including a vacuum detection mechanism, a vent valve arranged at the water return port, and a master controller for controlling the water return pump, the vacuum detection mechanism, the vent valve and the like; the water return pump is arranged in the water return pipeline and is close to the bottom of the swimming pool; the air vent valve is arranged beside the water return port and is closed in an initial state.
Above-mentioned scheme has solved the problem that current swimming pool return water mouth easily inhales the people to a certain extent, but this scheme mainly realizes the release of return water mouth suction through detecting return water mouth vacuum, need rely on vacuum test equipment, when vacuum test equipment detects the precision low or breaks down, takes place the human body easily and is stranded but the phenomenon that the return water mouth does not block up completely, and adaptability is poor, can't be applicable to ordinary swimming pool.
