Description

Technical Field

[0001] This application relates to the field of rainwater harvesting and treatment technology, specifically to a rainwater reuse flushing system. Background Technology

[0002] The rational collection and utilization of rainwater can replenish groundwater, reduce urban flood peaks, and effectively control surface water pollution, which is of great practical significance for improving the urban ecological environment and alleviating water scarcity.

[0003] In some common scenarios in life, some areas of residential communities or municipal roads are low-lying. When heavy rainfall occurs, the water on the road cannot be drained in time. This not only leads to severe water accumulation on the road, but also wastes a lot of rainwater resources. Prolonged waterlogging can also affect the service life of the road. How to make full use of this rainwater is a problem that technicians need to solve. Utility Model Content

[0004] The purpose of this application is to provide a rainwater reuse flushing system to solve the defects in the prior art where rainwater in some low-lying areas is not effectively utilized, resulting in resource waste.

[0005] To achieve the above objectives, this application employs the following technical solution:

[0006] A rainwater reuse flushing system, comprising

[0007] Safety diversion well;

[0008] A pretreatment unit, connected to any one of the interfaces in the safety diversion well, is used for preliminary filtration of rainwater flowing out of the safety diversion well.

[0009] Rainwater collection unit; the rainwater collection unit is connected to the outlet of the pretreatment unit and is used for secondary treatment and purification of the rainwater flowing into the pretreatment unit;

[0010] A brick-built valve well is provided, wherein a valve assembly connected to the rainwater collection section is provided inside the brick-built valve well to control the flow rate of rainwater discharged from the rainwater collection section.

[0011] In a further embodiment of this application, the pretreatment unit includes a sewage interception device and a diversion device, which are connected together. The sewage interception device is connected to any interface in the safety diversion well, and the diversion device is connected to the rainwater collection unit. The sewage interception device is used to intercept large-volume garbage in the rainwater flowing into the safety diversion well, and the diversion device is used to divert the initial rainwater.

[0012] In a further embodiment, the sewage interception device includes a sewage interception well and a collection frame. The collection frame is placed at the bottom of the sewage interception well and is connected to a winding device on the ground via a rope, or the rope is connected to the opening of the sewage interception well.

[0013] In a further embodiment, the diversion device includes a diversion well, the side wall of which is provided with a first outlet and a second outlet of different heights, and a baffle is radially installed on the inner wall of the diversion well via a torsion spring. The baffle is placed on the inner wall of the diversion well between the first outlet and the second outlet, and a float is tied to the baffle.

[0014] In a further embodiment of this application, the rainwater collection unit includes a collection tank, in which a sewage discharge well and a rainwater transfer well are installed. The sewage discharge well is located near the pretreatment unit and is used for discharging sludge from the collection tank. The rainwater transfer well is used for discharging rainwater from the collection tank.

[0015] In a further embodiment, a first pump body is installed at the bottom of the sewage well, and a grating is fixed around the first pump body. The first pump body is connected to the sludge tank through a sewage pipe. A second pump body is installed at the bottom of the rainwater transfer well, and a grating is fixed around the second pump body. The second pump body is connected to the brick-built valve well through a lift pipe.

[0016] In a further embodiment, the collection pool is buried underground, and the foundation of the collection pool includes a first concrete layer, a second concrete layer, and a membrane layer arranged from bottom to top. The collection pool is surrounded by a closed brick wall.

[0017] A further embodiment of this application also includes a control cabinet, which is signal-connected to the pretreatment unit, the rainwater collection unit, and the brick-built valve well.

[0018] The beneficial effects of this application are as follows:

[0019] The system in this application includes a pretreatment section and a rainwater collection section. The pretreatment section first performs initial pretreatment on the rainwater to remove larger impurities (garbage) and guides the initial rainwater flow to ensure the cleanliness of the rainwater entering the rainwater collection section. The rainwater collected in the collection section is then purified through sedimentation. Finally, the discharged rainwater can be used for watering flowers, washing cars, and sprinkling roads. The system can effectively purify rainwater for use, which not only reduces the drainage pressure on municipal drainage pipes but also effectively collects rainwater and reuses it, turning waste into treasure and alleviating water shortages.

[0020] The diversion device uses a float in conjunction with an elastically set baffle. The float rises and controls the opening and closing of the baffle based on the amount of water in the diversion well, thereby changing the direction of the water flow and ensuring the cleanliness of the rainwater entering the rainwater collection section as much as possible.

[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this application or its application or use.

[0027] like Figure 1 As shown, this embodiment discloses a rainwater reuse flushing system, which includes a safety diversion well 6, a pretreatment section, and a rainwater collection section connected by a DN300 pipe, and a brick-built valve well 5 connected to the rainwater collection section. The safety diversion well 6 is connected to a rainwater collection pipe 01, which guides the collected rainwater into the safety diversion well 6. Typically, the safety diversion well 6 has multiple outlets in multiple directions. The pretreatment section is connected to any one of the outlets in the safety diversion well 6 for preliminary filtration of the rainwater flowing out of the safety diversion well 6 (removing garbage bags, leaves, etc.). The rainwater collection section is connected to the outlet of the pretreatment section for secondary treatment and purification of the rainwater flowing into the pretreatment section, resulting in cleaner rainwater and improving the cleanliness of subsequent rainwater. The brick-built valve well 5 is connected to the rainwater collection section for transferring the secondary purified rainwater from the collection section to the external discharge.

[0028] In use, after rain, the rainwater flowing on the ground enters the safety diversion well 6 along the rainwater collection pipe 01. As the water level rises, the rainwater in the safety diversion well 6 enters the pretreatment section along the pipe. The pretreatment section performs two "lifting and storage" treatments on the incoming rainwater to ensure that the rainwater entering the rainwater collection section has a high degree of cleanliness. Finally, the rainwater settles in the rainwater collection section to obtain the clear upper layer of rainwater. After being pressurized, the rainwater can be used through the brick-built valve well 5 (usually for watering green plants, flushing toilets, and sprinkling roads, etc.).

[0029] Continue to observe the appendix Figure 1 In this embodiment, the pretreatment unit includes a sewage interception device 7 and a diversion device 8. The sewage interception device 7 and the diversion device 8 are also connected by a pipe. The sewage interception device 7 is connected to any one of the outlets in the safety diversion well 6. The diversion device 8 is connected to the rainwater collection unit through a pipe. The sewage interception device 7 includes a sewage interception well and a collection frame. The collection frame is placed at the bottom of the sewage interception well and is connected to the well opening by a rope. The collection frame is designed to accommodate large impurities such as leaves or garbage bags brought in by the rainwater, so as to intercept large garbage in the rainwater flowing into the safety diversion well 6. After long-term use, the collection frame needs to be cleaned manually. At this time, a rope is needed to lift the collection frame out of the well. In some embodiments, a winding device is installed at the well side to lift the collection frame. The winding device usually uses a winding motor in conjunction with a winding roller.

[0030] In this embodiment, the diversion device 8 includes a diversion well. The side wall of the diversion well is provided with a first outlet and a second outlet of different heights. A baffle is radially installed on the inner wall of the diversion well via a torsion spring. The baffle is placed on the inner wall of the diversion well between the first outlet and the second outlet. A float is tied to the baffle. The diversion device 8 is a relatively conventional product, which is briefly described here. If necessary, a rainwater diversion and filtration device with product model JZQL-200 can be used. During use, since the initial water flow is small and contains a large amount of impurities, the rainwater at this stage needs to be discarded during rainwater collection. The working principle of the diversion device 8 is to determine whether to let the rainwater flow into the rainwater collection section based on the flow rate when the rainwater enters. When the water volume is small, the baffle is in the open state, and the rainwater flows directly out from the lower second outlet. When the water volume is large, the continuously rising water level drives the float to rise and pull the baffle to close, and the rainwater flows into the rainwater collection section from the higher first outlet.

[0031] Observe again Figure 1In this embodiment, the rainwater collection unit includes a collection tank 1, in which a sewage discharge well and a rainwater transfer well are installed. The sewage discharge well is located near the pretreatment unit and is used to discharge sludge from the collection tank 1. The rainwater transfer well is used to discharge rainwater from the collection tank 1. A first pump body 2 is installed at the bottom of the sewage discharge well, and a grating 4 is fixed around the first pump body 2. The first pump body 2 is connected to the sludge tank through a sewage discharge pipe 02. A second pump body 3 is installed at the bottom of the rainwater transfer well, and a grating 4 is fixed around the second pump body 3. The second pump body 3 is connected to the brick-built valve well 5 through a lift pipe 03.

[0032] As attached Figure 1 and 2 As shown, in this embodiment, the collection pool 1 and each well are located underground. When installing the collection pool 1, excavation is carried out first. To prevent the foundation pit from collapsing, steel sheet piles must be driven before excavation. The second step is to compact the foundation. A 10cm layer of C15 plain concrete (first concrete layer 11) is laid on the compacted plain soil layer. Then, a 25cm thick layer of C30φ12@250 double-layer bidirectional reinforced concrete (second concrete layer 12) is laid. A membrane layer 13 is also laid on the surface of the upper second concrete layer 12. The collection pool 1 is placed stably on the surface of the membrane layer 13. At this time, a brick wall 14 is built around the collection pool 1, and a protective board is erected on the top.

[0033] In this embodiment, a valve assembly is installed in the brick-built valve well 5. One end of the valve assembly is connected to the second pump body 3, and the other end is connected to the output pipe 04. The opening and closing degree of the ball valve in the valve assembly is adjusted to regulate the water output of the output pipe 04, so that this part of the rainwater can be utilized. The valve assembly is a conventional technology, such as the ball valve switch and flow meter, which will not be described in detail here.

[0034] In some embodiments, the design has been optimized by adding a control cabinet 9, and the control cabinet 9 is wired to the rainwater collection unit and the brick valve well 5, which facilitates automated drainage and increases the practicality of the device.

[0035] Specific usage:

[0036] Rainwater flows into the rainwater collection pipe 01 and enters the interceptor 7 for filtering large impurities. It then flows into the diversion device 8. When the rainwater flow is low, it drains directly from the second outlet at the bottom into the sewage outlet. When the rainwater flow is high, it flows from the higher second outlet into the collection tank 1. After a period of sedimentation, the second pump 3 is activated to transfer the clear liquid from the upper layer to the valve assembly in the brick-built valve well 5. The final outflow is controlled by adjusting the opening and closing of the valve. The system periodically activates the first pump 2 to discharge the sludge deposited in the collection tank 1, ensuring the normal operation of the device. This system can solve the problem of road flooding caused by insufficient municipal drainage capacity, while also collecting and purifying rainwater, allowing for its reuse and turning waste into treasure.
