Description

Downstream type negative pressure eliminating system for swimming pool

Technical Field

The utility model relates to a following current formula swimming pool structure, especially a following current formula swimming pool negative pressure elimination system.

Background

In the design of a swimming pool, an indoor swimming pool usually adopts a counter-flow or mixed-flow circulation mode, a balance water tank is arranged in a swimming pool machine room, and a circulating water pump absorbs water from the balance water tank, so that the condition that a water suction pipe of the circulating water pump is directly connected with a water return port at the bottom of the swimming pool is avoided; however, in order to prevent the dirty water from flowing back to the swimming pool, the outdoor swimming pool usually adopts a forward flow type circulation mode, and cannot be provided with a balance water tank due to the limitation of the field. The conventional way of outdoor swimming pool sets up the moisturizing case at outdoor to the swimming pool moisturizing, and the circulating water pump suction pipe is direct to be connected with swimming pool bottom of the pool return water mouth, at the circulation in-process, causes swimming pool bottom of the pool water sucking mouth negative pressure easily, in case someone presses close to the return water mouth, will form very strong suction, takes place the incident of casualties, has great potential safety hazard, and this is also the outdoor swimming pool often appears drowned casualties's direct reason in return water mouthful department.

Although the new national regulations require that a button with a glass protective cover for emergently stopping the operation of the circulating water pump is arranged on the wall close to the seat of the safety rescuer on the bank, the hidden danger that people are injured by negative pressure at the water return port cannot be completely eliminated. In the prior art, an alarm is given only by detecting the vacuum degree of the recovery port, for example, a swimming pool water return port anti-human-sucking device with patent number CN201620272278.9 and publication date 20161012 comprises a vacuum detection mechanism, a vent valve and a master controller, wherein the vacuum detection mechanism, the vent valve and the master controller are arranged at the water return port; 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. The device is provided with vacuum detection mechanism, can detect the vacuum of swimming pool return water mouth at any time to trigger alarm device and send out the police dispatch newspaper, can effectively help stranded personnel to break away from danger, simple structure, extensive application. However, the device only plays a role in detection and alarm, negative pressure still exists in the swimming pool water return port, and the negative pressure cannot be eliminated, so trapped people adsorbed by the swimming pool water return port still exist, and potential safety hazards are caused. Therefore, the problem that the negative pressure of the water return port cannot be effectively eliminated exists in the prior art.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a following current formula swimming pool negative pressure elimination system. The utility model has the characteristics of simple structure effectively eliminates down flow swimming pool return water mouth negative pressure.

The technical scheme of the utility model: a negative pressure eliminating system for a downstream swimming pool comprises a water return pipe extending downwards at a water return port of the downstream swimming pool, an adjusting water tank is arranged below an outlet of the water return pipe, an air gap is reserved between an outlet of the water return pipe and an overflow liquid level of the adjusting water tank, and the adjusting water tank is connected with a water supply port of the downstream swimming pool through a circulating water pump to form circulation.

In the aforesaid one kind of concurrent swimming pool negative pressure elimination system, the height of the air gap is not less than 100mm.

In the forward flow swimming pool negative pressure eliminating system, the water return pipe is provided with a control valve.

In the downstream swimming pool negative pressure eliminating system, a water outlet of the regulating water tank is connected with the circulating water pump through a plurality of shunt pipes respectively, and a purifying device is arranged on the shunt pipes and positioned at the water absorption front end of the circulating water pump.

In the negative pressure eliminating system for the concurrent swimming pool, the purifying device comprises a hair collector.

In the negative pressure eliminating system for the forward flow swimming pool, the effective volume of the regulating water tank is not less than one twelfth of the circulating water volume of the forward flow swimming pool per hour.

In the negative pressure eliminating system for the forward flow swimming pool, the water outlet flow rate of the water return port is equal to the circulation flow rate of the forward flow swimming pool.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses a regulating reservoir has newly increased between the return water mouth of following current formula swimming pool and circulating water pump to set up the wet return that extends to regulating reservoir in return water mouth department, leave air gap between the bottom of wet return and regulating reservoir's the overflow liquid level, realize the air and cut off, thereby make no longer lug connection between return water mouth and the circulating water pump, but be the disconnected state, the water that return water mouth department flows belongs to the gravity effluent, circulating water pump's negative pressure can not transmit the return water mouth, the event has eliminated the negative pressure of return water mouth department.
