[0031] See also Figure 1-Figure 4 The present application provides a rainwater collection and treatment device, including a rainwater collector 1, a three-way valve 2, a sediment water treatment box 3, a turbid water treatment box 4, and a water storage tank 5; when in use, it is placed in some main flow channels where rainwater passes, such as drainage ditches, under the drainage pipes on the edge of the house, etc. The rainwater collector 1 is funnel-shaped to facilitate the inflow of rainwater.

[0032] A water outlet pipe is constructed at the lower end of the rainwater collector 1, and a three-way valve 2 is provided on the water outlet pipe; one water outlet end of the three-way valve 2 is connected to the sediment water treatment tank 3 through a pipeline, and the other water outlet end is connected to the turbid water treatment tank 4 through a pipeline; the water outlet of the sediment water treatment tank 3 is connected to the turbid water treatment tank 4 through a pipeline, and the water outlet of the turbid water treatment tank 4 is connected to the water storage tank 5 through a pipeline.

[0033] During operation, rainwater flows in from the upper port of the rainwater collector 1 and then flows out from the outlet pipe. The outflowing rainwater is distributed through the three-way valve 2. For the rainwater with a high sediment content in the early stage of rain, it is introduced into the sediment water treatment tank 3 for treatment after passing through the three-way valve 2. After removing large particles of debris in the water, it is introduced into the turbid water treatment tank 4 for treatment to remove small particles of debris in the outlet water; for the rainwater with a low sediment content in the middle and late stages of rain, it is directly introduced into the turbid water treatment tank 4 for treatment after passing through the three-way valve 2 to remove small particles of debris in the outlet water. The rainwater treated in the turbid water treatment tank 4 is finally introduced into the water storage tank 5 for storage.

[0034] This specific embodiment removes large particles of debris in the water through the sediment water treatment tank 3, removes small particles of debris in the water through the turbid water treatment tank 4, and then introduces it into the water storage tank 5 for storage, effectively avoiding secondary pollution caused by the fermentation of debris in the water, which is beneficial to improving the water quality and storage time of rainwater and facilitating subsequent use. At the same time, through the three-way valve 2, the initial rainwater that has just flowed is first introduced into the sediment water treatment tank 3 to remove large particles of debris in the water, and then introduced into the turbid water treatment tank 4 to remove small particles of debris in the water, which is beneficial to improving the service life of the turbid water treatment tank 4.

[0035] Optionally, in some specific embodiments, the setting heights of the sediment water treatment tank 3, the turbid water treatment tank 4, and the water storage tank 5 are sequentially lowered so that the collected rainwater can rely on gravitational potential energy to flow through the sediment water treatment tank 3, the turbid water treatment tank 4, and the water storage tank 5 in sequence. There is no need to use mechanical equipment such as water pumps to drive the rainwater to flow along a specific route, which is beneficial to reducing the use cost of the device.

[0036] Optionally, in some specific embodiments, the three-way valve 2 adopts an electric three-way valve, the three-way valve 2 is electrically connected to the controller, and the controller is also connected to a turbidity detector for detecting the turbidity of the water outlet from the rainwater collector 1. When working, the turbidity detector detects the turbidity of the collected rainwater in real time and transmits it to the controller. The controller controls the opening direction of the three-way valve 2 according to the input signal, and then controls the flow direction of the collected rainwater. No manual adjustment is required, thereby reducing the labor intensity of the staff and making it more convenient to use.

[0037] Optionally, in some specific embodiments, a porous partition 31 is vertically arranged in the sediment water treatment box 3, and the porous partition 31 divides the internal cavity of the sediment water treatment box 3 into a sedimentation chamber 32 and a preliminary filtration chamber 33, and the preliminary filtration chamber 33 is connected to the water outlet of the sediment water treatment box 3; the preliminary filtration chamber 33 is filled with pebbles.

[0038] After rainwater flows into the sediment water treatment box 3, it is first deposited in the sedimentation chamber 32 to remove sediments with large mass such as sediment, and then enters the preliminary filter chamber 33 through the porous partition 31 to remove suspended matter such as leaves floating in the water, and then passes through the preliminary filter chamber 33 to remove solid debris such as sediment suspended in the water, thereby achieving the purpose of removing large particles of debris in the water.

[0039] A debris baffle 34 with holes is installed obliquely in the sedimentation chamber 32. When there are debris in the sediment water treatment box 3 and rainwater starts to flow in, the debris baffle 34 is flushed, so that the debris on it gathers under the debris baffle 34. As the water level in the sediment water treatment box 3 rises, the floating objects in the rainwater gradually rise, and the debris below the debris baffle 34 is blocked by the debris baffle 34, so that these debris cannot float on the water surface, effectively preventing these debris from clogging the porous partition 31, and effectively ensuring the filtering performance of the preliminary filtering chamber 33.

[0040] Optionally, in some specific embodiments, a support frame 41 is horizontally arranged in the turbid water treatment box 4, and a gauze layer 42, an activated carbon layer 43, and a quartz sand layer 44 are arranged on the support frame 41 from bottom to top. When rainwater is introduced into the turbid water treatment box 4, it passes through the quartz sand layer 44, the activated carbon layer 43, and the gauze layer 42 in sequence. The solid suspended matter in the rainwater is further removed by the quartz sand layer 44, and then the chemical pollutants are removed by the activated carbon layer 43. Finally, it flows out after passing through the gauze layer 42. The cleanliness of the rainwater is effectively guaranteed through multi-layer filtration.

[0041] Optionally, in some specific embodiments, the water storage tank 5 includes a fixed base 51, a connecting tube 52, a movable cover 53, and a flexible liner 54; the flexible liner 54 is made of rubber, and its side is corrugated so that the internal space of the flexible liner 54 can be expanded and reduced; the fixed base 51 is configured with a bottom tube extending upward in the vertical direction, the upper end of the bottom tube is slidably connected to the lower end of the connecting tube 52, and the upper end of the connecting tube 52 is slidably connected to the movable cover 53, and the fixed base 51, the connecting tube 52 and the movable cover 53 constitute A water storage chamber, in which a flexible lining 54 is arranged; when rainwater is introduced into the water storage tank 5, as the water level rises, the flexible lining 54 gradually expands, driving the connecting tube 52 and / or the movable cover 53 to continuously move upward, thereby increasing the volume of the water storage chamber; when draining water, the connecting tube 52 and / or the movable cover 53 are driven downward under the action of gravity, squeezing the flexible lining 54, thereby increasing the water outlet pressure, which is beneficial to increasing the drainage speed. At the same time, the overall volume of the water storage tank 5 becomes smaller, which is beneficial to the transportation and storage of the water storage tank 5.

[0042] Optionally, in some specific embodiments, the connecting tube 52 is sleeved on the outer side of the bottom tube and the movable cover 53 to achieve sliding connection between the three. The inner side surfaces of the bottom tube and the movable cover 53 are provided with a slide groove, and the inner side surface of the connecting tube 52 is provided with a protrusion matching the slide groove to prevent relative rotation between the fixed base 51, the connecting tube 52 and the movable cover 53; a block is provided at the top of the slide groove to prevent separation between the fixed base 51, the connecting tube 52 and the movable cover 53.

[0043] The embodiments of the present application have been described above, and the above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments. The selection of terms used herein is intended to best explain the principles of the embodiments, practical applications, or improvements to the technology in the market, or to enable other persons of ordinary skill in the art to understand the embodiments disclosed herein.
