Problems solved by technology

[0003] Garden rainwater collection often does not attract people's attention, but it can also recycle a large amount of rainwater. After purification, it can be used in all aspects of family life. A large amount of sediment is attached to hinder the circulation of rainwater, slow down the filtration speed of rainwater, thereby reducing the efficiency of rainwater collection, and cannot maximize the collection and purification of rainwater. In addition, considering that the pollution degree of initial rainwater is the largest, it should be To design a device for treating initial rainwater, it is also necessary to consider that the rainfall in different time periods is different. In view of the above problems, it is necessary to design a new garden rainwater treatment device

Embodiment 1

[0040] Such as figure 1 As shown, this embodiment provides a garden rainwater collection and utilization system, including a water collection system, an initial rainwater collection system, a sedimentation system, a filtration system, a water storage system, and a central controller.

[0041] Specifically, such as figure 2 As shown, the water collection system includes a water collection tank 1, and a preliminary screening device 11 and a first water level sensor 12 located in the water collection tank 1, such as Figure 5 As shown, the preliminary screening device 11 includes a screen cloth 111 and a rotating motor 112. The two ends of the screen cloth 111 are connected to the side wall of the water collection tank 1 by a rotating shaft 113, and the rotating shaft 113 at one end is connected to the rotating motor 112, and the rotating shaft 113 at the other end is connected to the collecting tank 1. The side wall of the water tank 1 rotates and cooperates. The first water l...

Embodiment 2

[0048] This implementation provides a method for collecting and utilizing rainwater in a courtyard, which is realized by using the system for collecting and utilizing courtyard rainwater in Embodiment 1, including steps:

[0049] S1. Before it rains, if there is no water in the water collection tank 1, the first water level sensor 12 sends a signal that the water level is 0 to the central controller, and the central controller closes the first valve 61, the second valve 71, the third valve 14, fifth valve 25;

[0050] S2. When it started to rain, the rainwater in the courtyard was collected into the main pipe 13 through the ground pipes and culverts, and the rainwater flowed into the water collection tank 1 through the main pipe 13. After being simply filtered by the screen 111, the rainwater was first stored in the water collection tank 1. The first water level sensor 12 collects the information of the water level in the water collection tank 1, and transmits the above inform...

Embodiment 3

[0057] This implementation provides a method for collecting and utilizing rainwater in a garden, which is realized by using the system for collecting and utilizing rainwater in a garden in Embodiment 1. The steps of the method are basically the same as those in Embodiment 2, and the similarities will not be repeated here. The difference is that:

[0058] In S5: the central controller judges whether the rain stops according to the information transmitted by the first water level sensor 12, and judges whether the last reservoir 5 is full of water according to the information transmitted by the third water level sensor 51, as Figure 4 As shown, if the water level line of the last reservoir 5 does not reach the top of the reservoir 5 and the rain has stopped, the central controller closes the third valve 14 and opens the first valve 61 simultaneously, and the central controller also opens the fifth valve 25. The water in the lower water storage tank 23 enters the second coarse fil...

Abstract

The invention discloses a courtyard rainwater collection and utilization system and method. The system comprises a water collection system, an initial rainwater collection system, a precipitation system, a filtering system, a water storage system and a central controller. The water collection system comprises a water collection tank and a first water level sensor, and a third valve is arranged at the bottom of the water collection tank. The initial rainwater collection system comprises an initial water storage tank which is connected with the third valve through a drainage pipe, a fourth valve is arranged in the initial water storage tank and divides the initial water storage tank into an upper water storage tank and a lower water storage tank, a second water level sensor is arranged in the lower water storage tank, a fifth valve is further arranged at the bottom of the lower water storage tank, and the fifth valve is connected with the filtering system through a drain pipe. The water storage system comprises a reservoir and a third water level sensor. Initial rainwater is treated according to actual conditions, courtyard rainwater is collected and utilized to the maximum extent, the rainwater in the reservoir is used for cleaning a primary screening device, and accumulated silt and impurities are prevented from hindering circulation of the rainwater.

Description

technical field [0001] The invention belongs to the technical field of rainwater treatment, and in particular relates to a garden rainwater collection and utilization system and method. Background technique [0002] Water is an irreplaceable and extremely precious natural resource. Many regions in the world are on the verge of water resource depletion, and China is also a country with poor water resources. When the traditional way of water resource development can no longer increase the water source, recycling rainwater has become an economical and practical way of water resource development, which not only saves tap water, but also benefits the ecological balance. [0003] Garden rainwater collection often does not attract people's attention, but it can also recycle a large amount of rainwater. After purification, it can be used in all aspects of family life. A large amount of sediment is attached to hinder the circulation of rainwater, slow down the filtration speed of ra...
