Description

Technical Field

[0001] The present application relates to a rainwater collection device, in particular to a sponge city diversion type rainwater pollution prevention collection system. Background Art

[0002] Sponge city is a new generation of urban stormwater management concept, which means that the city has good "elasticity" in adapting to environmental changes and coping with natural disasters caused by rain. It absorbs, stores, infiltrates and purifies water when it rains, and releases and utilizes the stored water when needed.

[0003] In the prior art, people set up a collection box on the roof surface to collect rainwater, so as to use the collected rainwater to irrigate plants on sunny days. However, in real life, due to the influence of wind and rain, sometimes branches, plastic bags and other debris will be carried into the collection box, causing the collection box to be blocked.

[0004] Based on this, people set up filters at the mouth of the collection box to block debris such as branches and plastic bags; however, the long-term accumulation of debris on the surface of the filter will also affect the normal collection of rainwater, and the debris on the filter needs to be cleaned frequently, which needs to be improved. Summary of the invention

[0005] In order to automatically clean and collect debris to maintain normal collection of rainwater, the present application provides a sponge city diversion rainwater pollution prevention and collection system.

[0006] The present application provides a sponge city diversion type rainwater pollution prevention and collection system adopts the following technical solutions: A sponge city split-flow rainwater pollution-blocking collection system comprises a collection box, a water storage tank and a connecting pipe for connecting the collection box and the water storage tank, wherein a rotating drum is rotatably installed in the collection box, and the outer wall of the rotating drum abuts against the inner wall of the collection box; the collection box is provided with a driving member for driving the rotating drum to rotate, the middle part of the rotating drum has a cavity, the connecting pipe is connected with the cavity and abuts against the inner wall of the cavity; The outer wall of the rotating drum is circumferentially spaced with a plurality of collecting grooves connected to the cavity, and the upper wall of the connecting pipe is provided with a plurality of filter holes for connecting to the collecting grooves; a debris box is arranged at the bottom of the collecting box, and the debris box is used to collect debris in the collecting grooves.

[0007] By adopting the above-mentioned technical solution, when rainwater flows into the collection box, the starting drive drives the drum to start rotating. As the drum rotates, the rainwater will be evenly guided to each collection trough; when the rainwater flows through the collection trough, larger debris will be intercepted in the collection trough, and the clean rainwater will flow into the connecting pipe through the filter holes on the upper wall of the connecting pipe, and then flow into the water storage tank for use.

[0008] When the collection trough of the drum rotates downward and connects to the debris box, the debris falls into the debris box by its own weight and is collected regularly in the debris box, thereby maintaining smooth and efficient operation of the system. The rotation of the drum can scrape the debris on the surface of the filter holes and collect them in the debris box, which automatically cleans and collects the debris, thereby maintaining normal collection of rainwater. Only the debris box needs to be cleaned regularly, reducing maintenance workload.

[0009] Optionally, a filter plate is provided in the debris box, and the debris box is connected to the water tank through a transfer pipe.

[0010] By adopting the above technical solution, the debris dropped from the collection box into the glove box contains some rainwater. At this time, the rainwater can flow into the bottom wall of the collection box through the filter plate and into the water storage tank through the transfer pipe, thereby improving the rainwater collection effect.

[0012] By adopting the above technical solution, the first gear is connected to the scraper through the sliding assembly, so that when the drum rotates, the scraper will slide along the upper wall of the filter plate, scrape off the debris accumulated on the filter plate, and create a gap between the debris and the filter plate, thereby maintaining the filtering effect of the filter plate.

[0013] Optionally, the sliding assembly includes a third gear, a sliding frame and a sliding wheel, the third gear is rotatably installed on the collection box and meshes with the first gear; one end of the sliding frame is fixed to the scraper, and two opposite inner walls of the sliding frame are provided with tooth grooves; the sliding wheel is fixed to the axis of the third gear and is passed through the sliding frame; the outer wall of the sliding wheel is provided with a tooth portion, and the tooth portion is used to mesh with the tooth grooves on the opposite side walls of the sliding frame.

[0014] By adopting the above technical solution, when the third gear is driven to rotate by the first gear, the sliding wheel fixed to its axis will also rotate; because the outer wall tooth portion of the sliding wheel is meshed with the tooth groove on one side of the inner wall of the sliding frame, the rotation of the sliding wheel will be converted into the linear sliding of the sliding frame. At the same time, because one end of the sliding frame is fixed to the scraper, the scraper is driven to scrape off the upper surface of the filter plate; and when the tooth portion is meshed with the tooth groove on the other side of the sliding frame, the sliding direction of the sliding frame is reversed, so that the scraper can move back and forth on the upper surface of the filter plate.

[0015] Optionally, a plurality of partition rods are rotatably mounted on the scraper, and a plurality of support rods are obliquely arranged on the partition rods.

[0016] By adopting the above technical solution and arranging the separation rod, the debris on the filter plate can be dispersed to prevent the debris from agglomerating into a mass and causing blockage, so as to maintain the filtering effect of the filter plate.

[0017] Optionally, an ejection groove is formed on the outer bottom wall of the connecting tube, and the ejection groove is used to be connected with the collecting groove; an ejection plate is slidably installed in the ejection groove, and the connecting tube is provided with a movable component for driving the ejection plate to slide.

[0018] By adopting the above technical solution, the movable component drives the ejection plate to move in the ejection groove, so that the debris attached to the outer wall of the connecting pipe can be shaken off into the debris box, thereby improving the collection effect of the debris in the collection box.

[0019] Optionally, the movable assembly includes an ejector rod, a drive plate and a reset member, the drive plate is rotatably mounted on the inner wall of the connecting pipe through a rotating shaft; the inner wall of the connecting pipe is provided with a water collecting pipe for communicating with the filter hole, and one end of the drive plate covers an end of the water collecting pipe away from the filter hole; A sliding seat is slidably installed on the outer wall of the driving plate, one end of the ejection rod is rotatably installed on the sliding seat, the ejection groove is provided with an ejection hole, the other end of the ejection rod is passed through the ejection hole and connected to the ejection plate; the reset member is used to drive the driving plate to cover the water collecting pipe opening again.

[0020] By adopting the above technical solution, in the initial state, the driving plate covers the opening of the water collecting pipe, and the ejection plate is located at one end of the ejection groove close to the water collecting pipe.

[0021] When rainwater enters the connecting pipe through the filter holes, the rainwater first enters the water collecting pipe; as the amount of rainwater increases, the water level in the water collecting pipe gradually rises, generating pressure on the driving plate; and when the water pressure in the water collecting pipe reaches a certain level, the driving plate rotates around the rotating shaft, gradually exposing the opening of the water collecting pipe, allowing rainwater to flow into the connecting pipe; because the ejector rod is connected to the driving plate through the sliding seat, the ejector plate slides in the ejection groove and moves toward one side of the collecting groove.

[0022] When rainwater reduces the water pressure on the driving plate, the driving plate is driven by the reset member to cover the opening of the water collecting pipe to wait for the water level in the water collecting pipe to rise again, thereby causing the ejection plate to reciprocate in the ejection groove.

[0023] Optionally, the reset member is configured as a spring, the spring is sleeved on the outer wall of the ejector rod, and the two ends of the spring are respectively connected to the inner wall of the ejector groove and the ejector plate; the elastic force of the spring is used to drive the driving plate to cover the water collecting pipe.

[0024] By adopting the above technical solution, the elastic force of the spring is in a compressed or rope-pulling state, providing power for the reset of the driving plate, so that the ejection plate can reciprocate in the ejection groove.

[0025] Optionally, the driving plate is provided with a rubber pad for abutting against the water collecting pipe.

[0026] By adopting the above technical solution, the rubber pad can be set to increase the sealing performance of the driving plate covering the opening of the water collecting pipe, so that the water collecting pipe can collect rainwater, so that the rainwater in the water collecting pipe exerts pressure on the driving plate.

[0027] In summary, the present application includes at least one of the following beneficial technical effects: 1. By setting up a rotating drum, the rotation of the rotating drum can scrape off the debris on the surface of the filter holes and collect them in the debris box, which can automatically clean and collect the debris, thereby maintaining the normal collection of rainwater. It only needs to clean the debris box regularly, reducing the maintenance workload; 2. By setting the ejector plate, the movable assembly drives the ejector plate to move in the ejector groove, so that the debris attached to the outer wall of the connecting pipe can be shaken off into the debris box, thereby improving the collection effect of the debris in the collection box; 3. By setting the scraper and the partition rod, when the scraper slides on the upper surface of the filter plate, a gap can be created between the debris and the filter plate, and the partition rod can disperse the debris on the filter plate to prevent the debris from agglomerating and causing blockage, so as to maintain the filtering effect of the filter plate.

The upper wall of the second pipe 32 is provided with a plurality of filter holes 33 for communicating with the collecting tank 41. The two ends of the first pipe 31 are respectively connected with the second pipe 32 and the water storage tank 2. When debris and rainwater enter through the collecting port 11, the rainwater enters the second pipe 32 through the filter holes 33 and enters the water storage tank 2 through the first pipe 31. The debris is retained in the collecting tank 41 and changes position with the rotation of the drum 4.

[0041] Reference Figure 5A debris box 7 is provided at the bottom of the collection box 1, and the debris box 7 is used to collect debris retained in the collection groove 41; the debris box 7 is provided with a filter plate 71, and the debris box 7 is provided with a transfer pipe 77 for connecting the debris box 7 and the first pipe 31. The debris dropped into the debris box 7 from the collection box 1 contains some rainwater, and the rainwater can flow into the bottom of the collection box 1 through the filter plate 71; and then enter the water storage tank 2 through the transfer pipe 77, thereby improving the rainwater collection effect of the device.

[0042] A scraper 72 is slidably installed on the upper surface of the filter plate 71, and the slide is connected to the first gear 51 through a sliding assembly 8; a plurality of partition rods 73 are rotatably installed on the upper surface of the scraper 72, and a plurality of support rods 74 are provided on the partition rods 73; when the scraper 72 slides on the upper surface of the filter plate 71, a gap can be created between the debris and the filter plate 71, and the partition rods 73 can disperse the debris on the filter plate 71 to prevent the debris from agglomerating and causing blockage, so as to maintain the filtering effect of the filter plate 71.

[0043] Reference Figure 6 The sliding assembly 8 includes a third gear 81, a sliding frame 82 and a sliding wheel 83. The third gear 81 is rotatably installed in the collection box 1 and meshes with the first gear 51; the two ends of the sliding wheel 83 are respectively connected to the axis of the third gear 81 and the collection box 1, and the outer wall of the sliding wheel 83 is provided with a tooth portion 84.

The opposite side walls of the sliding frame 82 are provided with tooth grooves 85 for engaging with the sliding part.

[0045] When the third gear 81 is driven to rotate by the first gear 51, the sliding wheel 83 fixed to its axis will also rotate; because the outer wall tooth portion 84 of the sliding wheel 83 is meshed with the tooth groove 85 on one side of the inner wall of the sliding frame 82, the rotation of the sliding wheel 83 will be converted into the linear sliding of the sliding frame 82. At the same time, because one end of the sliding frame 82 is fixed to the scraper 72, the scraper 72 is driven to scrape the upper surface of the filter plate 71; and when the tooth portion 84 is meshed with the tooth groove 85 on the other side of the sliding frame 82, the sliding direction of the sliding frame 82 is reversed, so that the scraper 72 can move back and forth on the upper surface of the filter plate 71.

[0046] The implementation principle of the sponge city diversion type rainwater pollution prevention and collection system in the embodiment of the present application is: When rainwater flows into the collection box 1, the starter motor 53 drives the drum 4 to start rotating. As the drum 4 rotates, the rainwater will be evenly guided to each collection slot 41. When the rainwater flows through the collection slot 41, larger debris will be intercepted in the collection slot 41, and the clean rainwater will flow into the water collection pipe 36 through the filter hole 33. As the amount of rainwater increases, the water level in the water collection pipe 36 gradually rises, generating pressure on the drive plate 63. When the water pressure in the water collection pipe 36 reaches a certain level, the drive plate 63 rotates around the rotating shaft 66, gradually exposing the opening of the water collection pipe 36 and flowing into the second pipe 32.

[0047] Since the ejection rod 62 is connected to the driving plate 63 through the sliding seat, the ejection rod 62 can slide in the ejection hole 35, thereby driving the ejection plate 6 to slide in the ejection groove 34, so as to eject the debris when the collecting groove 41 of the rotating drum 4 is rotated to the bottom; and the elastic force of the spring can drive the driving plate 63 to cover the ejection groove 34 again, and the ejection plate 6 can slide in the ejection groove 34 for many times over and over again, so as to shake off the debris attached to the ejection plate 6, thereby improving the collection effect of the debris in the collection box 1.

[0048] The rotation of the drum 4 can scrape off the debris on the surface of the filter hole 33 and collect it in the debris box 7, which automatically cleans and collects the debris, thereby maintaining normal collection of rainwater. It only needs to clean the debris box 7 regularly, reducing the maintenance workload.

[0049] The above are preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
