[0033] A concrete cushion is arranged at the bottom of the rainwater collection pool, a reinforced concrete manhole cover is poured at the top, and a maintenance opening 12 is arranged. A waterproof layer is arranged inside. Water inlets 7 and outlets 8 are opened on both sides at the upper end, and a rainwater lift pump 10 is arranged at the bottom. The water outlet pipe 11 of the rainwater lift pump passes through the outlet and is connected to the park greening water supply pipe network.
[0034] There are two rainwater lift pumps, and one of them is used as a standby rainwater lift pump.
[0035] Both the safety diversion well and the rainwater collection pool are brick - built square well structures.
[0036] The floating ball control valve 9 includes a floating ball 13 and a water - cut-off valve 14.
[0037] Taking the pipe network construction of a certain park project as an example, the device of this solution is described in detail.
[0038] In this embodiment, the size of the safety diversion well is a brick - built square well of 1500mm * 1500mm * 2000mm. A 100 - mm - thick concrete cushion is provided at the bottom, and a reinforced concrete manhole cover is cast at the top with a maintenance opening. A rainwater inlet is provided on the left side inside, and water outlets are provided on both the right - rear sides: the left side is connected to the rainwater inlet, and after the rainwater enters the safety diversion well and precipitates, it flows into the rainwater composite filtration device from the right - side water outlet. A filter mesh is provided at the right - side rainwater outlet. After filtering the floating substances in the rainwater through the filter mesh, it then enters the rainwater composite filtration device through the rainwater pipe network and is discharged into the rainwater collection pool. A float water - cut - off valve is provided on the right side. When the water volume in the collection pool reaches the established water level, the water - cut - off valve automatically closes, so that the rainwater is discharged into the municipal rainwater pipe network from the rear - side water outlet to achieve the function of safe diversion. The rear - side rainwater outlet is connected to the municipal drainage pipe network and is higher than the right - side water outlet. When the water level of the pool reaches the predetermined water level, the water - cut - off valve automatically closes, and the excess rainwater flows into the municipal drainage system through the rear - side rainwater outlet to avoid pool overflow.
[0039] The size of the rainwater collection pool is a brick - built square well of 8000mm * 6000mm * 4000mm. The size of the pool can be set according to its own needs and on - site conditions. A 100 - mm - thick concrete cushion is provided at the bottom, and a reinforced concrete manhole cover is cast at the top with a maintenance opening; waterproof treatment is done inside. An inlet is provided at the upper end inside to connect to the right - side water outlet of the rainwater composite treatment device; Two 1.5 - KW rainwater lift pumps (one standby) are installed at the bottom of the pool. When greening irrigation operations are required, the rainwater lift pumps are turned on to effectively utilize the rainwater collected in the rainwater collection pool.
[0040] The specific principle and application process of this rainwater collection device are as follows:
[0041] The key to this solution is to implement an efficient rainwater treatment device, which is designed specifically to meet the needs of urban park greening irrigation; This device includes a safety diversion well, a composite filtration device, and a dedicated rainwater collection pool. The three work together to optimize the process of rainwater capture and utilization.
[0042] First of all, the safety diversion well plays a role of preliminary precipitation and filtration when receiving rainwater, using natural precipitation to effectively remove sludge and larger - particle impurities in the water. This process ensures the quality of the rainwater entering the collection pool and provides a preliminarily purified water source for subsequent treatment. The precipitated rainwater then enters the rainwater composite filtration device through the right - side water outlet, and in the rainwater composite filtration device, special treatment is carried out on the impurities in the rainwater, thereby improving the overall filtration efficiency.
[0043] Subsequently, the rainwater treated by the composite filtration device is guided to the rainwater collection pool. When the amount of collected rainwater reaches the preset safe water level of the pool, the float control valve in the safety diversion well will be automatically activated, closing the right outlet to prevent more rainwater from flowing in and preventing the system from overloading; the remaining rainwater is then diverted to the municipal rainwater pipe network through the rear outlet. This not only protects the collection system from excessive rainwater but also reduces the burden on the municipal drainage system.
[0044] In addition, a dedicated lift pump is installed in the rainwater collection pool to pump the treated clean rainwater into the irrigation system of the park greening water supply pipe network.
[0045] Through this series of design processes, this device not only effectively utilizes natural rainfall resources, reduces the dependence on traditional water sources, but also significantly optimizes the burden on the urban drainage system, making an important contribution to environmental protection and the sustainable development of urban greening. The implementation of this system provides a sustainable and environmentally friendly water resource management solution for urban parks.
[0046] The intelligent rainwater collection system includes the rainwater collection device. Among them, a water level and water quality sensor is installed in the safety diversion well, and a control panel is installed near the rainwater collection pool. The control panel is electrically connected to the water level and water quality sensor respectively.
[0047] One output terminal of the control panel is electrically connected to the control terminal of the float control valve.
[0048] Based on the rainwater collection device, this system includes an intelligent monitoring system. A water level and water quality sensor is installed in the safety diversion well to monitor the collection and quality status of rainwater in real time, and the system is adjusted in real time through a control panel located near the collection pool. The control panel makes the operation of the system more convenient and ensures the efficient management of water resources.
[0049] Pump design: The collection pool is equipped with a lift pump for transporting clean rainwater to the park irrigation system when needed.
[0050] Compared with the prior art, this rainwater collection system not only simplifies the installation and maintenance processes through optimized design and intelligent monitoring, but also improves the utilization efficiency of rainwater and the environmental adaptability of the system, significantly reducing the operating cost and effectively supporting the sustainable greening needs of urban parks.
[0051] The introduction of this intelligent system not only enhances the functionality of the rainwater collection system but also greatly improves its operation convenience and real-time response ability.
