Description

Technical Field

[0001] This utility model belongs to the field of rainwater harvesting technology, specifically, it relates to a self-cleaning roof rainwater harvesting device. Background Technology

[0002] Rooftop rainwater harvesting, as a common method of rainwater collection, provides a certain amount of water resources for non-potable purposes such as irrigation and toilet flushing around buildings.

[0003] After prolonged use, the filters of existing rooftop rainwater harvesting devices are prone to clogging, affecting rainwater collection efficiency. Manual cleaning is time-consuming and labor-intensive. In addition, some devices cannot effectively remove impurities carried in rainwater in the early stages of rainwater collection, resulting in poor water quality and high subsequent purification costs.

[0004] In view of this, this utility model is hereby proposed. Utility Model Content

[0035] Example 1

[0036] Please refer to Figure 1-5 A self-cleaning roof rainwater collection device includes: a main body 1; a guide shell 2 installed on one side of the main body 1; a filter screen 3 installed on the upper side of the guide shell 2; a collection pipe 4 installed on the lower side of the guide shell 2; a filter shell 5 installed on one side of the main body 1; a filter perforated plate 6 installed on the lower side of the inner wall of the filter shell 5; a drain pipe 7 fixedly connected to the lower side of the filter perforated plate 6; a cleaning mechanism 8 installed inside the filter shell 5; a sewage pipe 9 fixedly connected to one side of the filter shell 5; and a collection box 10 fixedly connected to one side of the main body 1. One end of the collection pipe 4 is connected to one side of the filter shell 5, and one end of the sewage pipe 9 is connected to one side of the collection box 10. A cleaning door 11 is rotatably fitted on one side of the collection box 10. Two spring clips 12 are installed on one side of the cleaning door 11, and two mating blocks 13 that cooperate with the spring clips 12 are installed on one side of the collection box 10. A protective shell 14 is installed on one side of the filter shell 5, and multiple heat dissipation grooves 15 are opened on the lower side of the protective shell 14. A guide plate 16 that cooperates with the collection pipe 4 is installed on the lower side of the inner wall of the guide shell 2.

[0037] Implementation Process: During rainfall, rainwater from the roof flows under gravity towards the guide shell 2 installed on one side of the main building 1. The filter screen 3 on the upper side of the guide shell 2 first filters and intercepts larger impurities in the rainwater, such as leaves and branches, preventing them from entering the subsequent collection system and causing blockages. The rainwater that has undergone preliminary filtration quickly collects along the guide plate 16 on the lower side of the inner wall of the guide shell 2 and flows into the filter shell 5 through the collection pipe 4. The guide plate 16 can effectively guide the rainwater to the collection pipe 4, improving the rainwater collection efficiency. After entering the filter shell 5, the rainwater first falls on the filter perforated plate 6, which further filters the smaller particulate impurities remaining in the rainwater. The purified rainwater passes through the filter... The perforated plate 6 is discharged through the drain pipe 7. The cleaning door 11 on one side of the collection box 10 is rotatably fitted to facilitate the periodic opening and cleaning of the collected impurities. The two spring clips 12 on the cleaning door 11 cooperate with the two mating blocks 13 on one side of the collection box 10 to ensure the sealing of the cleaning door 11 when it is closed, preventing impurities from leaking out. The protective shell 14 installed on one side of the filter shell 5 protects key components such as the drive motor 86 from direct splashing of rainwater or collision with foreign objects that could damage the motor. The multiple heat dissipation slots 15 on the lower side of the protective shell 14 can dissipate the heat generated by the drive motor 86 during operation in a timely manner, ensuring the normal and stable operation of the motor and extending the service life of the equipment.

[0038] Benefits of implementation: The dual filtration structure, with filter screen 3 and filter plate 6 working together, can effectively remove impurities of different sizes from rainwater, greatly improving the degree of rainwater purification and providing a higher quality water source for subsequent rainwater utilization.

[0039] Example 2

[0040] The cleaning mechanism 8 includes a drive disc 81 rotatably fitted on the inner wall of the filter housing 5. Multiple arc-shaped filter housings 82 are mounted on the outer side of the drive disc 81. Flexible scrapers 83 are fixedly connected to the outer sides of the arc-shaped filter housings 82. An installation groove 84 is formed on one side of the inner wall of the filter housing 5. A cleaning brush 85 is mounted on one side of the inner wall of the installation groove 84. A drive motor 86 is mounted on one side of the filter housing 5. The output end of the drive motor 86 is fixedly connected to one side of the drive disc 81. The flexible scraper 83 engages with the upper side of the filter plate 6 and the inner wall of the filter housing 5. The cleaning brush 85 engages with the arc-shaped filter housings 82.

[0041] Implementation process: The drive motor 86 starts, and its output end drives the drive disc 81 to rotate on the inner wall of the filter shell 5. Multiple arc-shaped filter shells 82 mounted on the outside of the drive disc 81 rotate synchronously. The flexible scraper 83, fixedly connected to the outside of the arc-shaped filter shell 82, moves close to the upper side of the filter plate 6 and the inner wall of the filter shell 5 during rotation. On one hand, the flexible scraper 83 scrapes away impurities that may clog the filter holes on the filter plate 6, causing them to fall back to the bottom of the filter shell 5, preventing clogging and affecting the filtration effect. On the other hand, it also cleans the dirt and other impurities attached to the inner wall of the filter shell 5, ensuring the rainwater collection path is unobstructed. When the arc-shaped filter shell 82 rotates past the mounting groove 84, The cleaning brush 85 installed on one side of the inner wall of the mounting groove 84 will contact the arc-shaped filter shell 82 to scrub away any impurities that may adhere to the surface of the arc-shaped filter shell 82, preventing impurities from accumulating on the arc-shaped filter shell 82, and further ensuring the continuous and efficient operation of filtration and cleaning. Impurities accumulated at the bottom of the filter shell 5 can be discharged through the drain pipe 9. One end of the drain pipe 9 is connected to the filter shell 5, and the other end is connected to one side of the collection box 10. The discharged impurities are collected in the collection box 10 to avoid secondary pollution to the environment. The filtered and purified rainwater is finally collected through the drain pipe 7 to a suitable water storage facility or directly used for non-potable irrigation, toilet flushing, and other purposes, realizing the effective utilization of rainwater.

[0042] Benefits of implementation: The unique cleaning mechanism 8 design, with the drive disc 81, arc-shaped filter housing 82 and flexible scraper 83 working together, automatically cleans the filter components in real time, ensuring that the filtration system always maintains a high filtration efficiency, reducing manual maintenance costs and cleaning frequency, and solving the problems of easy clogging and difficult cleaning of traditional rainwater collection devices.
