Description

Technical Field

[0001] The utility model relates to the technical field of rainwater collection and reuse, in particular to a siphon rainwater collection and reuse system. Background Art

[0002] Siphonic rainwater drainage uses the Bernoulli equation to calculate the pressure in the drainage pipe, changes the pressure change in the drainage pipe by changing the diameter of the pipe and pipe fittings, forms a full pipe flow, and quickly drains water under the action of pressure. The roof siphonic rainwater drainage system is generally suitable for large factories and large public buildings. The usual sponge city construction in building communities requires that the gravity flow discharge system on the roofs of residential, office, and teaching buildings should disconnect the rainwater riser and lead it to sunken green spaces, bioretention facilities and other facilities, which can effectively control the total runoff, runoff peak, and runoff pollutants. However, the siphonic rainwater drainage system generates siphon force to accelerate the drainage speed of rainwater. An energy dissipation well must be set up at the outlet of the house, and the water directly enters the rainwater pipe network through the energy dissipation well and then discharges into the municipal rainwater pipe network, which fails to control the runoff and absorption of rainwater.

[0003] At present, the common practice is to use roof siphon rainwater to directly enter the park rainwater pipe network, and set up a large water storage tank before entering the municipal rainwater pipe network to meet the annual runoff control rate of rainwater. In this way, the roof rainwater will pass through a long pipe network, which will cause water pollution and increase the cost of rainwater purification. Secondly, a larger water storage tank will require a larger area.

[0004] In the prior art, there is a rainwater collection and treatment system that uses physical and chemical principles for purification, and passes through multiple structures such as reservoirs, sedimentation tanks, activated carbon mechanisms, and pure water reservoirs, and uses water pumps to lift and recycle the rainwater multiple times. It has the problems of high energy consumption, large land area, and lengthy process.

[0005] Therefore, the inventor, relying on his many years of experience and practice in related industries, proposes a siphon rainwater collection and reuse system to overcome the defects of the prior art. Utility Model Content

[0033] Figures 1 to 4 As shown, the utility model provides a siphon rainwater collection and reuse system, comprising:

[0034] Roof siphon rainwater system for siphoning and collecting roof rainwater;

[0035] An energy dissipation well 7 for hydraulic buffering, the outlet of the roof siphon rainwater system is connected to the energy dissipation well 7; the energy dissipation well overflow pipe 9 is connected to the energy dissipation well 7, and the inlet of the energy dissipation well overflow pipe 9 is lower than the outlet of the roof siphon rainwater system;

[0036] A water storage tank 10 is provided below the energy dissipation well 7; the energy dissipation well 7 is connected to the water storage tank 10 through a well-pool connecting pipe 8 which is inclined downward; the inlet of the well-pool connecting pipe 8, the outlet of the roof siphon rainwater system and the inlet of the energy dissipation well overflow pipe 9 are all located at the upper part of the water storage tank 10, and the inlet of the well-pool connecting pipe 8 is provided below the outlet of the roof siphon rainwater system and the inlet of the energy dissipation well overflow pipe 9; the water storage tank 10 is connected to a water storage tank overflow pipe 13, and the overflow water level of the energy dissipation well 7 is the same as that of the water storage tank 10; the water storage tank 10 is connected to a water pump 14.

[0037] The sizes of the energy dissipation well 7 and the water reservoir 10 are determined according to different scales of use.

[0038] The utility model is an improvement on the conventional roof siphon rainwater. The rainwater collected by the roof siphon rainwater system first enters the energy dissipation well 7, which plays a certain role in water flow buffering and sedimentation. After reaching a certain water level, the rainwater enters the reservoir 10. After the reservoir 10 is full of water, it can be used for greening irrigation and road cleaning through the water pump 14. The energy dissipation well 7 has the same overflow water level as the reservoir 10, ensuring that it overflows to the rainwater pipe network after the reservoir is full of water (existing technology). At the same time, it can also overflow directly to the rainwater pipe network through the energy dissipation well 7, ensuring that the rainwater can be discharged in time. The utility model is mainly used in siphon rainwater collection and reuse systems, and can also be used for rainwater collection and reuse in other systems.

[0039] Aiming at the practical problem that the discharge volume of the existing roof siphon rainwater system is greater than that of the gravity roof rainwater drainage system, and thus directly enters the energy dissipation well and is discharged into the rainwater pipe network, the utility model establishes a siphon rainwater collection and reuse system, which can effectively achieve the total amount of rainwater annual runoff control, and at the same time effectively collect and reuse it for greening irrigation and road cleaning, etc., to avoid waste of water resources. The system is simple to operate, low in cost, saves energy consumption, improves the waste of rainwater resources, has a good rainwater purification effect, and can effectively improve the utilization rate of rainwater.

[0040] The utility model can effectively solve the problem of siphon rainwater utilization, greatly reduce the pollution degree in the process of rainwater discharge, and is flexible to set up and occupies a small area. The system achieves the purpose of rainwater recycling through a simple and efficient method, and is expected to be widely used in actual projects.

Multiple connecting pipes 3 are connected through a suspension pipe 4, and are led to the outdoors through a rainwater riser 5, and finally enter the energy dissipation well 7 through a riser buried pipe 6. The huge siphon negative pressure suction force and the high potential energy of the rainwater riser 5 cause the rainwater to fall quickly, and hydraulic buffering is performed in the energy dissipation well.

[0044] When the rainwater reaches a certain water level in the energy dissipation well 7, it flows into the water storage tank 10 by gravity through the energy dissipation well 7 and the well pool connecting pipe 8.

When the energy dissipation well 7 and the water tank 10 both reach the overflow water level, they are discharged into the rainwater pipe network through the energy dissipation well overflow pipe 9 and the water tank overflow pipe 13 by gravity flow respectively.

[0046] Furthermore, the slopes of the vertical pipe buried pipe 6, the well-pool connecting pipe 8, the energy dissipation well overflow pipe 9 and the water storage tank overflow pipe 13 are all greater than or equal to 0.3%.

[0047] In a specific embodiment, the inlet of the well pool connecting pipe 8 is 200 mm lower than the outlet of the roof siphon rainwater system; the inlet of the energy dissipation well overflow pipe 9 is 100 mm lower than the outlet of the roof siphon rainwater system.

Sediment in rainwater can enter the groove 12 through the inclined plate 11, effectively purifying rainwater.

[0049] An inclined plate 11 is arranged at the bottom of the water reservoir 10 and connected to the groove 12, which plays a good role in sedimentation and purification. The pollutants accumulated in the groove 12 can be cleaned by regular suction.

[0050] Further, if Figure 1 , Figure 4As shown, a pump stop water level marking unit 15 is provided on the side wall of the water storage tank 10. The purified rainwater can be lifted and recycled by a variable frequency mobile pump, and the pump stop water level marking unit 15 stops lifting water to prevent the sludge at the bottom of the pool from being.

[0051] In a specific embodiment, the dimension of the pump stop water level marking unit 15 above the highest point of the inclined plate 11 is greater than 300 mm.

[0052] Furthermore, the water pump 14 is a variable frequency mobile pump. When the water reservoir 10 is full of water, the water can be used for greening irrigation and road cleaning through the variable frequency mobile pump.
