Description

Technical Field

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

[0002] In modern urban construction and environmental protection, rainwater harvesting devices are receiving increasing attention. These devices can not only effectively collect and utilize rainwater resources, but also reduce the burden on urban drainage systems and mitigate the environmental impact of surface runoff. In rainwater harvesting devices, filters are an indispensable component, as they can filter out debris such as leaves and sand from rainwater, ensuring the quality of the collected rainwater.

[0003] However, existing rainwater harvesting devices are prone to filter clogging by debris during use, which reduces the filtration efficiency and can even affect the normal operation of the entire rainwater harvesting system. Currently, although some rainwater harvesting devices use cleanable filter designs, this is usually achieved by manually or mechanically moving the cleaning device on the filter. During the cleaning process, debris inside the filter pores is not completely removed, and it is difficult to remove very thin debris such as leaves and plastic bags that greatly affect the collection efficiency. Additional steps or tools are often required for cleaning, increasing the complexity and cost of maintenance.

[0004] In view of this, a rainwater harvesting device is proposed. Utility Model Content

Detailed Implementation

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0035] Please see Figure 1-13 .

[0036] This utility model rainwater collection device includes a collection box 1 and a drain pipe 101 opened at the bottom of the collection box 1. A filter component 2 is detachably installed on the top of the collection box 1. The filter component 2 includes a mounting frame 21, a filter screen 22 fixedly connected to the top of the mounting frame 21, and a cleaning plate 23 for cleaning the filter screen 22 slidably arranged at the bottom of the mounting frame 21. Multiple push-out blocks 231 adapted to the aperture of the filter screen 22 are fixedly connected to the cleaning plate 23. A cleaning comb 3 is slidably arranged on the collection box 1. The comb on the cleaning comb 3 is staggered from the multiple push-out blocks 231. When the push-out blocks 231 are pushed out from the filter screen 22, the cleaning comb 3 removes the debris originally inside or above the aperture of the filter screen 22 by moving. This arrangement allows the push-out blocks 231 to push out stones and other debris stuck in the aperture of the filter screen 22 and remove them through the cleaning comb 3. It can also lift up and clean very thin debris such as leaves that are difficult to clean.

[0037] It should be noted that when setting up, the aperture size of the filter screen 22 is the same as the cross-sectional size of the ejector block 231. In addition, the distance between the apertures of the filter screen 22 is the same as the distance between two adjacent ejector blocks 231, while the size of the cleaning comb 3 is slightly smaller than the distance between two adjacent ejector blocks 231.

[0038] Secondly, both sides of the mounting bracket 21 are fixedly connected to first sliders 24 with a T-shaped cross section. The top of the collection box 1 is provided with a first groove 25 that matches the size of the two first sliders 24. Both sides of the cleaning comb 3 are fixedly connected to second sliders 4 with a T-shaped cross section. The collection box 1 is provided with a second groove 5 that matches the size of the two second sliders 4. A motor 6 is fixedly connected to the collection box 1. Gears 7 are rotatably connected to both sides of the collection box 1. The two gears 7 are fixedly connected to each other by a connecting rod 9. The output end of the motor 6 is fixedly connected to either of the two gears 7. Both sides of the cleaning comb 3 are fixedly connected to racks 8. The two racks 8 are meshed with the two gears 7 respectively. This arrangement enables the cleaning comb 3 to move smoothly, improves cleaning efficiency, and reduces the difficulty of manual operation. It can automatically clean the filter screen 22 when it becomes clogged in heavy rain.

[0039] Specifically, in its initial state, the top of the ejector block 231 overlaps with the bottom of the filter screen 22 and is offset from the aperture of the filter screen 22. Movable blocks 19 are fixedly connected to both sides of the cleaning plate 23. The mounting bracket 21 has tracks 20 for limiting the movement of the movable blocks 19. Figure 6 and Figure 9 As shown, the track 20 is L-shaped, and its shape is the same as the movement path of the movable block 19. This arrangement ensures that the track 20 can limit the movable block 19 and the cleaning plate 23, and ensures that the ejector block 231 can be accurately aligned with the aperture of the filter screen 22 when it rises.

[0040] In addition, the staggered arrangement of the ejector block 231 and the filter screen 22 in the initial state is to avoid the ejector block 231 affecting the normal filtration effect of the filter screen 22.

[0041] Furthermore, a first electric push rod 14 is fixedly connected to the collection box 1. An L-shaped connecting plate 15 is fixedly connected to the extended end of the first electric push rod 14. A third slider 17 is fixedly connected to the connecting plate 15. A third sliding groove 18, matching the size of the third slider 17, is provided on the collection box 1. A second electric push rod 16, arranged laterally, is fixedly connected to the connecting plate 15. Two mounting strips 10 are slidably arranged on the collection box 1. Multiple limiting blocks 11 are fixedly connected to the mounting strips 10. A limiting groove 12, matching the size of the multiple limiting blocks 11, is provided at the bottom of the cleaning plate 23. Block 11 and limiting groove 12 are used to clamp the mounting strip 10 to the cleaning plate 23. A drive rod 13 is fixedly connected between the two mounting strips 10. The drive rod 13 is detachably connected to the extended end of the second electric push rod 16. The first electric push rod 14 is used to adjust the horizontal position of the cleaning plate 23 and the ejector block 231, and the second electric push rod 16 is used to adjust the vertical position of the cleaning plate 23 and the ejector block 231. This arrangement enables precise positioning of the cleaning plate 23 and the ejector block 231 through the precise control of the two electric push rods, thereby improving the automation and accuracy of cleaning.

[0042] It should be noted that, in specific settings, protective covers can be added to the first electric push rod 14, the second electric push rod 16, and the motor 6 to prevent rainwater from affecting the normal operation of the device. In addition, the power source for the electric push rod and the motor 6 can be a solar panel or other device.

[0043] Furthermore, the extension distance of the first electric push rod 14 is the same as the height of the ejector block 231, and the extension distance of the second electric push rod 16 is the same as the distance by which the ejector block 231 and the filter screen 22 are misaligned. When the cleaning plate 23 moves the ejector block 231 to the highest point, the highest height of the ejector block 231 is slightly lower than the highest height of the groove of the cleaning comb 3, to prevent debris from getting stuck on the cleaning comb 3.

[0044] Secondly, both the collection box 1 and the mounting frame 21 are provided with channels 201 for the vertical movement of the mounting strip 10. The channel 201 is designed to facilitate the movement of the mounting strip 10 and also allows the device to adapt to filter screens 22 of different thicknesses, increasing the versatility of the device.

[0045] In addition, the length of the rack 8 is greater than the length of the filter screen 22 to ensure that it can clean all parts of the filter screen 22. This setting ensures that the cleaning comb 3 can cover the entire length of the filter screen 22, achieving comprehensive cleaning and ensuring the cleaning effect of the cleaning comb 3 in conjunction with the ejector block 231 on the filter screen 22.

[0046] When the device is working, if the filter screen 22 becomes clogged, the second electric push rod 16 first drives the drive rod 13 to move, causing the cleaning plate 23 to move the ejector block 231 to the area below the corresponding aperture of the filter screen 22. Then, the first electric push rod 14 drives the drive rod 13 to rise, causing the ejector block 231 to be ejected from the aperture of the filter screen 22. At this time, smaller debris such as pebbles in the aperture of the filter screen 22 is ejected, and larger debris such as leaves above the filter screen 22 that are difficult to clean are lifted up. Then, the motor 6 starts and drives the cleaning comb 3 from one end of the filter screen 22 to the other end through the meshing of the gear 7 and the rack 8, cleaning both the larger and smaller debris together. Then, the motor 6 reverses and the cleaning comb 3 resets and cleans again. Finally, the first electric push rod 14 and the second electric push rod 16 retract in sequence, and the entire device resets and re-enters the rainwater collection state.

[0047] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
