Description

Technical Field

[0001] This utility model relates to the field of rainwater harvesting and reuse structural design, and in particular to building roof structures for rainwater harvesting and reuse. Background Technology

[0002] In today's increasingly water-scarce environment, rainwater, as a precious natural resource, is receiving increasing attention in the construction industry for its collection and reuse. Building rooftops, as ideal locations for rainwater harvesting, can effectively alleviate urban water supply pressure and reduce water costs through rational structural design. They can also reduce the burden of rainwater runoff on urban drainage systems, which is of great significance for building a green and sustainable built environment. This water resource utilization method is widely used in various types of buildings, from ordinary residences to commercial complexes, all actively exploring and implementing efficient rainwater harvesting and reuse solutions.

[0003] Currently, some existing technologies in rainwater harvesting and reuse building roof structures use simple filter screens to treat collected rainwater. However, these filters are often complex to install and fix, and replacing them often requires multiple tools and a cumbersome process. For example, some filters are fixed in confined and inaccessible spaces, requiring workers to spend considerable time and effort removing surrounding components to reach the filter for replacement, increasing maintenance and time costs. Furthermore, after prolonged use, dirt and silt easily accumulate at the bottom of the collection device, making cleaning equally inconvenient. Some devices lack dedicated cleaning structures, or their cleaning structures are poorly designed, resulting in a labor-intensive and resource-intensive cleaning process that may even lead to partial damage to the device. Therefore, designing a rainwater harvesting and reuse building roof structure that facilitates filter replacement and easy cleaning of dirt and silt has become an urgent technical problem to be solved. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a rainwater harvesting and reuse building roof structure, which aims to solve the problem that existing rainwater harvesting and reuse building roof structures cannot quickly replace the filter screen.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A rainwater harvesting and reuse roof structure includes a rainwater collection box, a rain storage box fixedly connected to the right side of the rainwater collection box, an installation frame fixedly connected to the bottom side of the inner wall of the rain storage box, an installation groove on the top side of the installation frame, a filter screen installed inside the installation groove, a limit strip connected to the rear side of the rain storage box via a fixing component, a limit groove on the bottom side of the limit strip, the top of the filter screen located inside the limit strip, a lifting plate installed inside the rainwater collection box, and movable plates installed at both ends of the bottom side of the rainwater collection box, the rear end of the right side of the left movable plate and the front end of the left side of the right movable plate are connected to the bottom side of the lifting plate via a connecting component, and a sediment collection groove is provided on the top side of the lifting plate.

[0007] Furthermore, the fixing component includes a rotating plate, the bottom side of which is connected to the top side of the rain storage tank via a rotating shaft, the limiting strip is slidably connected inside the rotating plate, and the rear side of the rotating plate is rotatably connected to a limiting block.

[0008] Furthermore, a fixing groove is provided on the front side of the rain storage box, the front end of the limiting strip is located inside the fixing groove, and a receiving frame is fixedly connected to the rear end of the rain storage box.

[0009] Furthermore, the connecting assembly includes a second rotating shaft, the top side of which is fixedly connected to the bottom side of the lifting plate, a connecting rod rotatably connected to the bottom side of the second rotating shaft, and a third rotating shaft rotatably connected to the bottom side of the connecting rod. The two adjacent sides of the third rotating shafts at both ends are fixedly connected to the rear end of the right side of the left movable plate and the front end of the left side of the right movable plate, respectively.

[0010] Furthermore, the rain collection box is equipped with a sliding rod inside.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1 and Figure 5This utility model provides an embodiment of a rainwater harvesting and reuse roof structure, including a rainwater collection box 1. A rainwater storage box 3 is fixedly connected to the right side of the rainwater collection box 1. An installation frame 18 is fixedly connected to the bottom side of the inner wall of the rainwater storage box 3. An installation groove is opened on the top side of the installation frame 18, and a filter screen 15 is installed inside the installation groove. A limiting strip 2 is connected to the rear side of the rainwater storage box 3 through a rotating plate 10. A limiting groove 14 is opened on the bottom side of the limiting strip 2. The top of the filter screen 15 is located inside the limiting strip 2. A lifting plate 16 is installed inside the rainwater collection box 1. Movable plates 17 are provided at both the left and right ends of the bottom side of the rainwater collection box 1. The rear end of the right side of the left movable plate 17 and the front end of the left side of the right movable plate 17 are connected by a rotating shaft 2. 20 is connected to the bottom side of the lifting plate 16. The top side of the lifting plate 16 is provided with a sludge collection groove 19. The front side of the rain storage box 3 is provided with a fixing groove 8. The front end of the limiting strip 2 is located inside the fixing groove 8. The rear end of the rain storage box 3 is fixedly connected with a receiving frame 9. The interior of the rain storage box 1 is provided with a sliding rod 21. The left side of the sliding rod 21 is fixedly connected to the left side inside the rain storage box 1. The right side of the sliding rod 21 is fixedly connected to the right side of the mounting frame 18. The sliding rod 21 passes through two moving plates 17. The front side of the rain storage box 1 is provided with a through groove 5. The front end of the moving plate 17 is fixedly connected with a slider 7. The slider 7 is located inside the through groove 5. The bottom right side of the rain storage box 3 is provided with a drain pipe 4. The front end of the rain storage box 1 is slidably connected with a fixing piece 6.

[0026] Specifically, when putting it into use, the first step is to install the device on the roof. Once it rains, rainwater will flow into the rainwater collection tank 1 through the opening at the top. After flowing into the rainwater collection tank 1, the rainwater will immediately pass through the filter screen 15 and then enter the rainwater storage tank 3. The filtered rainwater can then be discharged and used as needed.

[0027] Reference Figure 2-4 The bottom side of the rotating plate 10 is connected to the top side of the rain storage box 3 through the rotating shaft 13. The limiting strip 2 is slidably connected inside the rotating plate 10, and the rear side of the rotating plate 10 is rotatably connected to the limiting block 11.

[0028] Specifically, over time, the impurities trapped by the filter screen 15 will gradually affect the filtration effect, at which point it needs to be replaced. Replacing the filter screen requires no complicated tools; simply rotate the limiting block 11 to release the restriction on the limiting strip 2. Next, pull the front end of the limiting strip 2 out of the fixing groove 8, and then rotate the rotating shaft 13, causing the rotating plate 10 and the limiting strip 2 to rotate together, inserting the rear end of the limiting strip 2 into the receiving frame 9. At this point, the restriction on the filter screen 15 is released, and replacement can be easily completed.

[0029] Reference Figure 1 , Figure 5 and Figure 6The top side of the second rotating shaft 20 is fixedly connected to the bottom side of the lifting plate 16. The bottom side of the second rotating shaft 20 is rotatably connected to the connecting rod 12. The bottom side of the connecting rod 12 is rotatably connected to the third rotating shaft 22. The two ends of the third rotating shaft 22 are respectively fixedly connected to the rear end of the right side of the left moving plate 17 and the front end of the left side of the right moving plate 17.

[0030] Specifically, after long-term use, a large amount of dirt and sludge will accumulate in the sludge collection tank 19. To clean these impurities, simply push the sliders 7 at both ends. The sliders 7 will drive the two moving plates 17 to move synchronously. The two moving plates 17 will then lift the lifting plate 16 through the connecting rod 12, so that the lifting plate 16 leaves the interior of the rainwater collection box 1. At this time, the dirt and sludge in the sludge collection tank 19 can be thoroughly cleaned.

[0031] Working principle: In use, the device is first installed on the roof. When it rains, rainwater enters the rainwater collection box 1 through the opening on the top side of the collection box 1. After entering the rainwater collection box 1, the rainwater is filtered by the filter screen 15 and then enters the rainwater storage box 3, where the filtered rainwater is discharged. When the filter screen 15 needs to be replaced, the limiting block 11 can be rotated to release the limiting strip 2, and then the front end of the limiting strip 2 can be moved out of the fixing groove 8. Then, the rotating shaft 13 can be rotated to drive the rotating plate 10. The limit bar 2 is rotated and its rear end is inserted into the receiving frame 9, thereby releasing the limit on the filter screen 15, so that the filter screen 15 can be replaced. At the same time, after a long period of use, there will be a lot of dirt and sludge inside the sludge collection tank 19. By moving the sliders 7 at both ends, the two moving plates 17 can be moved, thereby lifting the lifting plate 16 through the two connecting rods 12 and making the lifting plate 16 leave the inside of the rainwater collection box 1, so that the dirt and sludge inside the sludge collection tank 19 can be cleaned.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
