System complexity and cost: Some systems may be too complex and have high installation and maintenance costs, which limits their popularity and application. Utility Model Content

[0003] The utility model provides a rainwater collection system for greening irrigation, which can solve the problems of limited filtering efficiency, overly complex system and high installation and maintenance costs of existing rainwater collection systems.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a rainwater collection system for greening irrigation, comprising a safety diversion well and a rainwater collection pool, the safety diversion well is located on one side of the upper part of the rainwater collection pool, the bottom of one side of the safety diversion well is connected to the rainwater collection pool through a water inlet pipe of the collection pool, the upper side of the safety diversion well is connected to the rainwater pipe network of the residential area, the bottom of the safety diversion well is also connected to the municipal rainwater pipe network, a filter screen and a liquid level sensing control valve are arranged in the water inlet pipe of the collection pool, a pool sewage pump and a rainwater lifting pump are installed at the bottom of the rainwater collection pool, the pool sewage pump is connected to the outdoor sewage well, and the rainwater lifting pump is connected to the greening water supply pipe network of the residential area.

[0005] Preferably, the liquid level sensing control valve comprises a stop valve for controlling the on-off of the water inlet pipe of the collection tank and a float ball matching the stop valve.

[0006] Preferably, the bottom of the rainwater collection pool forms a low-surface trough and a high-surface portion, the pool sewage pump is installed in the low-surface trough, and the rainwater lifting pump is arranged on the upper side of the high-surface portion.

[0007] Preferably, inspection well covers are provided on the tops of the safety diversion well and the rainwater collection pool.

[0008] Preferably, the safety diversion well and rainwater collection pool are both arranged on the lower side of the green ground of the community, and the inspection well covers are exposed above the green ground of the community.

[0009] Compared with the prior art, the beneficial effects of the utility model are:

[0010] The structure is simple. The safety diversion well will initially filter the impurities in the rainwater in the rainwater pipe network during the rainy period through the filter mesh, and discharge the initially filtered rainwater to the rainwater collection pool for collection; when the rainfall during the rainy period is too heavy, the water level in the rainwater collection pool reaches the predetermined water level, and the collection pool inlet pipe automatically closes to prevent excessive rainwater from being discharged into the rainwater collection pool, and the rainwater is discharged to the municipal rainwater pipe network through the other end. The rainwater collection pool is equipped with a pool sewage pump and a rainwater lifting pump. After the rainwater collected in the pool is naturally precipitated, it is discharged to the greening water supply network through the rainwater lifting pump. The impurities precipitated in the pool are regularly discharged to the community sewage network through the pool sewage pump. Adding a rainwater collection system at the end of the community water supply network to collect rainwater during the rainy period for use in water facilities with lower water quality requirements such as greening irrigation will help reduce dependence on groundwater and other water sources, while reducing water bill expenditures, and has good use and promotion value.

[0015] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0016] like Figure 1-2As shown, the utility model solves the problems of limited filtering efficiency, overly complex system and high installation and maintenance cost of the existing rainwater collection system. The following technical scheme is provided: a rainwater collection system for greening irrigation, comprising a safety diversion well B and a rainwater collection pool A, wherein the safety diversion well B is located on one side of the upper part of the rainwater collection pool A, and the bottom of one side of the safety diversion well B is connected to the rainwater collection pool A through the collection pool inlet pipe 5, and the upper side of the safety diversion well B is connected to the community rainwater pipe network 1, and the bottom of the safety diversion well B is also connected to the municipal rainwater pipe network 2, and the collection pool inlet pipe 5 is provided with a filter 10 and a liquid level sensing control valve 4, and the bottom of the rainwater collection pool A is installed with a pool sewage pump 6 and a rainwater lifting pump 9, and the pool sewage pump 6 is connected to the outdoor sewage well, and the rainwater lifting pump 9 is connected to the community greening water supply pipe network C.

[0017] Specifically, the safety diversion well B is a 1500mm*1500mm*2000mm brick-built square well, with a 100mm thick concrete cushion at the bottom, a reinforced concrete manhole cover 3 on the top and an inspection port. The rainwater collection pool A is a 7000mm*4000mm*4500mm brick-built square well. The size of the pool can be set according to its own needs and site conditions, with a 100mm thick concrete cushion at the bottom, a reinforced concrete manhole cover 3 on the top and an inspection port, and the interior is waterproofed.

[0018] The pool sewage pump 6 can adopt a 1.5KW sewage pump, and two can be set, one for use and one for backup. The rainwater booster pump 9 can adopt a 3KW booster pump, and two can be set, one for use and one for backup. When greening irrigation operations are required, the rainwater booster pump is turned on to utilize the rainwater collected in the rainwater collection pool.

[0019] In this embodiment, the liquid level sensing control valve 4 includes a stop valve for controlling the on and off of the collection pool water inlet pipe 5 and a float matched with the stop valve. The float can be connected to the switch of the stop valve through a connecting rod. The float can extend to the inside of the rainwater collection pool A.
