Description

Technical Field

[0001] This utility model relates to a purification device, specifically a sponge city water storage tank purification device, and belongs to the technical field of purification devices. Background Technology

[0002] Sponge city, a new generation of urban stormwater management concept, refers to a city's ability to adapt to environmental changes and cope with natural disasters caused by rainwater, much like a sponge. It can also be called a "water-resilient city." A sponge city's storage tank is a rainwater harvesting facility used to collect and store rainwater. The storage tank can temporarily retain peak rainwater runoff, allowing it to gradually drain after the maximum flow has decreased. This achieves the goals of mitigating peak stormwater runoff, improving rainwater utilization, controlling initial rainwater pollution of receiving water bodies, and playing a positive role in drainage scheduling between drainage areas.

[0003] In the construction of sponge cities, rainwater storage tanks are indispensable. Currently, these tanks require purification devices to filter and purify the collected rainwater. However, these devices are easily clogged by debris such as leaves, causing the purification process to stall. Furthermore, debris can enter the purification devices, affecting their effectiveness. Existing technologies often employ the following methods to address this issue:

[0004] (1) Add pretreatment facilities: Set up pretreatment facilities, such as sedimentation tanks or filters, in front of the water storage tank to remove large particulate impurities in the rainwater, such as leaves.

[0005] (2) Regular cleaning and maintenance: Regularly check the operation of the water storage tank and purification device, and clean and maintain them in a timely manner, including removing debris from the water storage tank and cleaning the purification device.

[0006] (3) Add a filtration device: Add a filtration device, such as a filter screen or filter cloth, at the inlet of the water storage tank to further remove impurities entering the water storage tank.

[0007] While the above methods can be effective to some extent, the newly added filter device will still become clogged during pre-treatment filtration and cannot be automatically cleaned.

[0008] To address this, a water purification device for sponge city reservoirs is proposed. Utility Model Content

[0032] The gear ring 17 is fixedly connected to the upper surface of the water storage tank 11 by three mounting brackets 24. The water inlet filter cartridge 16 is fixedly connected to the upper surface of the water storage tank 11. The conical cap 22 is fixedly connected to the upper surface of the water inlet filter cartridge 16. The gear 18 is fixedly connected to the top of the outer side wall of the rotating shaft 19. The top of the rotating shaft 19 is fixedly connected to the output shaft of the drive motor 15. The adjacent ends of the two cleaning brushes 14 are symmetrically fixedly connected to the bottom of the outer side wall of the rotating shaft 19. The controller 13 is installed on the inner side wall of the waterproof box 23. The mounting ring 21 is fixedly connected to the lower surface of the water storage tank 11. The lower surface of the rotating ring 12 is rotatably connected to the upper surface of the gear ring 17.

[0033] In one embodiment, the drive motor 15 is mounted on the upper surface of the rotating ring 12, and the outer side wall of the gear 18 is meshed with the inner side wall of the gear ring 17. Thus, when the drive motor 15 drives the rotating shaft 19 to rotate, the rotating ring 12 rotates.

[0034] In one embodiment, the waterproof box 23 is installed on the upper surface of the rotating ring 12, and the drive motor 15 is located inside the waterproof box 23. The waterproof box 23 can protect the drive motor 15 and the controller 13.

[0035] In one embodiment, bristles are provided on the lower surface and at the far ends of the two cleaning brushes 14. The bristles at the bottom of the cleaning brush 14 are attached to the upper surface of the water storage tank 11, and the bristles at the end of the cleaning brush 14 are attached to the outer wall of the water inlet filter cartridge 16. Thus, the water inlet filter cartridge 16 and the water storage tank 11 can be cleaned by the cleaning brushes 14.

[0036] In one embodiment, a main body assembly 301 is installed on the lower surface of the water storage tank 11. The main body assembly 301 includes an inner filter cylinder 31, a coarse sand layer 32, a fine sand layer 33, a water filter sand layer 34, a purification cylinder 35, and a water storage tank body 36.

[0037] The water storage tank 11 is installed on the upper surface of the main body 36 of the water storage tank. The inner filter cylinder 31 is threaded to the inner side wall of the mounting ring 21. The inner filter cylinder 31 is located inside the purification cylinder 35. The purification cylinder 35 is threaded to the outer side wall of the mounting ring 21. The inner filter cylinder 31 and the purification cylinder 35 are installed by threaded connection, which is convenient for cleaning and replacement.

[0038] In one embodiment, a coarse sand layer 32, a fine sand layer 33, and a filter sand layer 34 are laid sequentially from top to bottom inside the purification cylinder 35, and rainwater can be purified through the coarse sand layer 32, the fine sand layer 33, and the filter sand layer 34.

[0039] In one embodiment, the electrical output terminal of the controller 13 is electrically connected to the electrical input terminal of the drive motor 15 via a relay. The electrical input terminal of the controller 13 is connected to an external power supply to power the drive motor 15. The model of the controller 13 is: OHR-PR10.

[0040] When this utility model is in operation: rainwater gathers at the center of the water storage hopper 11, and after being filtered by the inlet filter 16, it flows into the interior of the main body 36 of the water storage tank. The inlet filter 16 can filter large particles such as leaves in the rainwater. Then, the rainwater is filtered a second time by the inner filter 31 to prevent impurity particles from flowing into the purification cylinder 35. Then, the rainwater is purified by the coarse sand layer 32, the fine sand layer 33 and the filter sand layer 34. The purified rainwater flows into the bottom of the main body 36 of the water storage tank.

[0041] The controller 13 sets the timer for the drive motor 15, which in turn drives the rotating shaft 19 to rotate. The rotating shaft 19 drives two cleaning brushes 14, which rotate around the rotating shaft 19. This cleaning brushes 14 can clean impurities on the surface of the water tank 11 and impurities filtered by the inlet filter cartridge 16, preventing impurities from clogging the inlet filter cartridge 16. At the same time, the rotating shaft 19 also drives the gear 18 to rotate. The gear 18 meshes with the gear ring 17 through its teeth. Since the position of the gear ring 17 is fixed, the rotating ring 12 rotates under the cooperation of the drive motor 15, the rotating shaft 19, the gear 18, and the gear ring 17. The rotating shaft 19 rotates around the axis of the rotating ring 12 while rotating on its own axis. Thus, the cleaning brushes 14 can achieve a comprehensive cleaning of the water tank 11 and the inlet filter cartridge 16, improving the cleaning effect.
