Description

Rainwater storage system for fire fighting of high-rise building

Technical Field

The application relates to the field of rainwater is accomodate, especially relates to a rainwater system of accomodating for high-rise building fire control.

Background

At present, the condition of water source shortage can be effectively relieved through rainwater collection and cyclic utilization, so that the rainwater utilization is a necessary engineering project for a plurality of buildings in recent years, and a rainwater recycling system in a building area adapts to the current situation and the demand of a city with good water-saving benefit and environmental ecological benefit, and is an important direction for future water resource utilization.

In the rainwater collection system, rainwater is generally guided by using drainage ditches and then collected, however, in the rainwater collection process, rainwater in the case of large rain can be collected, and for light rain, the rainwater is difficult to flow to the drainage ditches due to low flow and light weight, so that the rainwater is difficult to collect, and the inventor thinks that the rainwater collection system needs to be improved.

Disclosure of Invention

Also can collect the rainwater in order to rain when rainfall is less, this application provides a rainwater storage system for high-rise building fire control.

The application provides a pair of rainwater storage system for high-rise building fire control adopts following technical scheme:

the utility model provides a rainwater storage system for high-rise building fire control, includes a plurality of collecting assembly, the collecting assembly is including the collecting box that is used for collecting the rainwater, collecting box top opening, the collecting assembly is including being used for leading to close collecting box open-ended seal the piece and be used for the drive seal the piece and open automatically collecting box open-ended driving piece, the both sides of the roof of collecting box still are equipped with the guiding gutter respectively, the guiding gutter is opened there is the water inlet, the bottom of water inlet with the collecting box roof flushes, seal a lateral wall and form the water guide face of slope and partly outstanding the collecting box roof, the collecting box intercommunication has the feed pipe, feed pipe and building fire-fighting water pipe intercommunication.

By adopting the technical scheme, when rainwater is small, the sealing block seals the opening of the collecting box, rainwater flows to the water inlet after falling on the top wall of the collecting box, and then rainwater can be collected, and part of rainwater falls on the water guide surface of the sealing block and flows downwards to the top wall of the collecting box along the water guide lower surface, so that rainwater deposited on the top wall of the collecting box is converged and drives the rainwater on the top wall of the collecting box to flow to the water inlet due to inertia, the situation that the rainwater is difficult to continue flowing after falling on the top wall of the collecting box when the rainwater is small is favorably reduced, the rainwater is more easily flowed to the water inlet, and the effect of collecting rainwater when the rainwater is small can be achieved; meanwhile, the sealing block blocks the opening of the collecting box, which is favorable for reducing the condition that rainwater flows into the collecting box and is deposited on the bottom wall of the collecting box, when the rain is heavy, the rainwater flows into the collecting box, the water guide groove walls on the two sides can block the rainwater, the condition that the rainwater flows out of the collecting box from the two sides of the collecting box is reduced, the rainwater can flow into the collecting box more easily, when the rain stops, the sealing block blocks the opening of the collecting box again, and the rainwater in the collecting box is difficult to evaporate in the flowing process to the water supply pipe.

Preferably, a water filtering membrane is sleeved in the collecting box, and the edge of the water filtering membrane penetrates through the top end opening of the collecting box and extends out of the collecting box.

Through adopting above-mentioned technical scheme, when rain is great, carry more sand and dust easily in the rainwater and blown to half empty rubbish by the strong wind, when rubbish and sand and dust follow the rainwater and flow to the collecting box in, rubbish and sand and dust can be blockked by the drainage membrane to make comparatively clean rainwater flow and collect to the feed pipe, be favorable to purifying the rainwater of collecting.

Preferably, the driving piece comprises a guide rod arranged in the collecting box and a spring sleeved on the guide rod, the sealing block slides on the guide rod, one end of the spring is fixedly connected with the guide rod, the other end of the spring is fixedly connected with the bottom end of the sealing block, and when the sealing block seals the opening of the collecting box, the spring is in a compression state.

Through adopting above-mentioned technical scheme, when rain is great, the rainwater promotes the length direction gliding of seal piece along the guide bar, make seal piece and collecting box opening separation, thereby make the rainwater can flow to the collecting box in from the gap between seal piece and the collecting box opening part perisporium, when the seal piece glides down in the promotion of rainwater, because the flow that flows on the seal piece is nearly average, consequently the seal piece receives the gravity of the rainwater that flows on its upper surface and keeps gliding to the state of separating with the collecting box roof, make the rainwater sustainable flow collect in the collecting box.
