Description

Technical Field

[0001] This utility model relates to the field of rainwater diversion technology, specifically to a rainwater diversion control device. Background Technology

[0002] Rainwater diversion and control equipment diverts rainwater to different interception wells or treatment units through guiding structures (drainage plates, float valves, etc.), and then discharges it according to actual needs. By setting up sensors to monitor parameters such as rainfall, water quality, and water level in real time, and combining with an intelligent control system to dynamically adjust the diversion path, it can greatly reduce the sewage treatment load, improve drainage efficiency, and promote the recycling of water resources.

[0003] Currently, rainwater diversion and control equipment typically uses self-cleaning grilles, rotary filters, or high-pressure washing equipment. These devices achieve automatic cleaning through mechanical scraping or water flushing to reduce debris accumulation and solve the clogging problem to some extent.

[0004] However, in the actual operation of rainwater diversion and control equipment, debris such as leaves and plastics can still clog the grid or valves of the interception well, resulting in a reduction in the water delivery of the pipes connected to the interception well, obstruction of water flow, and long-term blockage can cause equipment damage, increase maintenance costs, and even affect the stability of the drainage system. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a rainwater diversion control device to reduce the blockage of the interception well's grille or valve by debris such as leaves and plastic, thereby reducing maintenance costs and improving the stability of the drainage system.

[0006] The technical solution adopted by this utility model to solve the technical problem is as follows: a rainwater diversion and control device, including a rainwater collection tank and a first pipe fitting. One end of the first pipe fitting is fixedly connected to a first intercepting well. A guide hood is fixedly connected to the upper side of the inner wall of the first intercepting well. A spiral guide groove is fixedly connected to the bottom side of the guide hood. A negative pressure traction pipe is fixedly connected to the central axis of the spiral guide groove. A return frame is fixedly connected to one side of the negative pressure traction pipe. A traction pump is fixedly connected to the side of the return frame away from the first intercepting well. A baffle is set inside the return frame at the bottom side of the traction pump. A return pipe is fixedly connected to one side of the bottom end of the return frame. A second pipe fitting is fixedly connected to the side of the first intercepting well away from the traction pump. One end of the second pipe fitting is fixedly connected to a sediment treatment frame. A third pipe fitting is fixedly connected to one side of the sediment treatment frame. One end of the third pipe fitting is fixedly connected to a second intercepting well. A monitoring well is set between the second intercepting well and the sediment treatment frame. A PLC controller is set to one side of the monitoring well. The monitoring well is fixedly connected to the third pipe fitting.

[0007] As a preferred technical solution of this utility model, an operation slot is provided on one side of the upper end of the return frame, and a sealing plate is inserted into the operation slot. A distance sensor is fixedly connected to the sealing plate near the side of the baffle. By setting the distance sensor to monitor the water level in the return frame, it is easy to understand the blockage of the baffle, thereby reminding and handling the operator.

[0008] As a preferred technical solution of this utility model, a receiving strip is fixedly connected to the side of the return frame near the traction pump. The receiving strip is in contact with the baffle. A recess is provided on the side of the return frame near the first intercepting well, and the recess corresponds to and contacts the other side of the baffle. By setting the receiving strip in conjunction with the recess on the return frame, the baffle can be received, thereby facilitating the filtration of large leaves and plastic impurities.

[0009] As a preferred technical solution of this utility model, a check valve is provided on the bottom side of the return frame. The upper end of the check valve is fixedly connected to the return pipe. By setting the check valve, misoperation can be reduced and water can be prevented from flowing back from the return pipe into the return frame.

[0010] As a preferred technical solution of this utility model, the mud and sand treatment frame is in contact with a baffle frame. The baffle frame is open on the side near the second pipe fitting. Filter screens are evenly arranged on the baffle frame. A handle is fixedly connected to the upper end of the baffle frame. By setting the baffle frame and filter screen, mud and sand can be further treated, and the treatment of mud and sand can be facilitated, thus improving the convenience of treatment.

[0011] This utility model has the following advantages: by using the first intercepting well in conjunction with the return frame and the negative pressure traction structure, it can treat larger impurities in the water (such as leaves, plastics, etc.). Then, the rainwater flows into the sediment treatment frame and works with the baffle to treat the sediment in the water, which can improve the sediment treatment effect and further reduce the blockage problem caused by the flow of rainwater in the intercepting well.

[0016] The present invention will be further described below with reference to the accompanying drawings.

[0017] Please refer to the following: Figure 1-3 The rainwater diversion and control device shown includes a rainwater collection tank 1 and a first pipe fitting 2. One end of the first pipe fitting 2 is fixedly connected to a first intercepting well 3. The rainwater collection tank 1 is connected to multiple first intercepting wells 3 through multiple first pipe fittings 2. A guide hood 4 is fixedly connected to the upper side of the inner wall of the first intercepting well 3. The guide hood 4 can guide the water entering from the rainwater collection tank 1, thereby causing the rainwater to move along the spiral guide channel 5 to the bottom of the first intercepting well 3. The bottom side of the guide hood 4 is fixedly connected to the spiral guide channel 5, and the spiral guide channel 5 has two sides. The inner wall is equipped with a guardrail to enhance the guidance of rainwater. Simultaneously, the spiral guide channel 5 creates a swirling flow through tangential water intake. The central area experiences low pressure due to centrifugal force, causing water to move downwards along the spiral guide channel 5 and pushing heavy particles to settle at the bottom of the well. Under the continuous action of the water flow, sediment enters the sediment treatment frame 12 for filtration. By separating and filtering impurities of different sizes, the likelihood of clogging of the grid and mesh structure can be reduced. A negative pressure traction pipe 6 is fixedly connected to the central axis of the spiral guide channel 5. A return frame 7 is fixedly connected to one side of the first intercepting well 3. A traction pump 8 is fixedly connected to the side of the return frame 7 away from the first intercepting well 3. The traction pump 8 draws air to create a negative pressure state between the return frame 7 and the negative pressure traction pipe 6, thereby achieving the traction of leaves, plastic and other impurities located in the center. A baffle 9 is installed inside the return frame 7 at the bottom side of the traction pump 8. A return pipe 10 is fixedly connected to one side of the bottom of the return frame 7. A second pipe fitting 11 is fixedly connected to the side of the first intercepting well 3 away from the traction pump 8. The second pipe fitting 11 is lower than the third pipe fitting 13. One end of component 11 is fixedly connected to a sediment treatment frame 12, and a third pipe fitting 13 is fixedly connected to one side of the sediment treatment frame 12. One end of the third pipe fitting 13 is fixedly connected to a second intercepting well 15. A monitoring well 14 is provided between the second intercepting well 15 and the sediment treatment frame 12. A PLC controller is provided on one side of the monitoring well 14 (the PLC control cabinet is also connected to sensors for monitoring water quality and rainfall, and can achieve the diversion control of rainwater through integrated control). The monitoring well 14 is fixedly connected to the third pipe fitting 13.

[0018] The return frame 7 has an operation slot 16 on one side of its upper end. A sealing plate 17 is inserted into the operation slot 16. A distance sensor 18 is fixedly connected to the side of the sealing plate 17 near the baffle 9. By setting the sealing plate 17 and the distance sensor 18, the situation of leaves, plastic and other materials blocking the baffle 9 can be monitored.

[0019] Among them, a receiving strip 21 is fixedly connected to the side of the return frame 7 near the traction pump 8. The receiving strip 21 is in contact with the baffle 9. A recess is provided on the side of the return frame 7 near the first intercepting well 3. The recess corresponds to and is in contact with the other side of the baffle 9. By setting the receiving strip 21 and the recess, the baffle 9 can be received and disassembled.

[0020] Among them, a check valve 22 is provided on the bottom side of the return frame 7. The upper end of the check valve 22 is fixedly connected to the return pipe 10. By setting the check valve 22, the impact on the return pipe 10 during negative pressure traction can be reduced.

[0021] The mud and sand treatment frame 12 is in contact with a baffle 19. The baffle 19 is open on the side near the second pipe 11. Filter screens are evenly arranged on the baffle 19. A handle 20 is fixedly connected to the upper end of the baffle 19. By setting a movable baffle 19, the mud and sand entering the mud and sand treatment frame 12 can be filtered.

[0022] Among them, the first pipe fitting 2, the second pipe fitting 11 and the third pipe fitting 13 are all equipped with electrically controlled valves, which are used to control the direction of rainwater.

[0023] Working principle: Rainwater is collected in the rainwater collection tank 1 and then enters multiple first intercepting wells 3 through the first pipe 2. Under the action of gravity, the water rotates and moves downward. Lighter impurities such as leaves and plastics move to the bottom center of the first intercepting well 3, while heavier impurities such as sand and soil enter the sediment treatment frame 12 through the second pipe 11. After being filtered by the baffle frame 19, the water is further filtered and then enters the second intercepting well 15 through the monitoring well 14. When the return frame 7 or the sediment treatment frame 12 is blocked, it can be cleaned manually by disassembly.

[0024] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0025] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0026] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
