[0044] Combination Figures 1 to 10 As shown, this utility model proposes a rainwater harvesting and utilization device for sponge cities. This device can collect and filter rainwater, and finally transport the purified rainwater to various water-using devices 6 through a water pump 5, thus realizing the effective utilization of rainwater. The device mainly includes a temporary storage tank 1, a rainwater collection unit 2, a filter box 3, a water storage tank 4, and a water pump 5.

[0045] Combination Figure 1As shown, the temporary storage tank 1 serves as a preliminary storage container for rainwater, ensuring that a large amount of rainwater can be temporarily stored during heavy rainfall, thus avoiding resource waste caused by direct discharge of rainwater. A water inlet is provided at the top of the temporary storage tank 1, which is connected to the rainwater collection unit 2 so that the collected rainwater can smoothly enter the temporary storage tank 1.

[0046] Combination Figure 2 As shown, the rainwater collection unit 2 mainly includes components such as umbrella blades 21, support handles 22, risers 23, and connecting rods 24. Among them, the riser 23 is vertically arranged with openings at both the top and bottom. The bottom end of the riser 23 is connected to the interior of the temporary storage box 1 so that rainwater can flow smoothly into the interior of the temporary storage box 1.

[0047] Combination Figure 3 As shown, multiple support handles 22 are evenly distributed on the umbrella blade 21. The ends of the support handles 22 are all connected to the top of the riser 23, making the outer contour of the umbrella blade 21 resemble an inverted umbrella. This structural design increases the rainwater collection area and improves the rainwater collection efficiency. To enhance the stability of the umbrella blade 21, a connecting rod 24 is added to the bottom of the umbrella blade 21. One end of the connecting rod 24 is connected to the side wall of the riser 23, and the other end is connected to the middle of the support handle 22, forming a stable triangular support structure. This allows the umbrella blade 21 to withstand the impact of rainwater and also has good wind pressure resistance.

[0048] Meanwhile, the surface of the umbrella blade 21 is also coated with a waterproof coating to further improve its weather resistance and ensure that it can still maintain good working condition even in long-term rainfall.

[0049] The connecting rod 24 and support handle 22 of the rainwater harvesting unit 2 are made of high-strength lightweight alloy material. This material is lightweight, high-strength, and corrosion-resistant, which can effectively extend the service life of the rainwater harvesting unit 2 and ensure that the device can work normally under harsh weather conditions.

[0050] Combination Figure 2 As shown, combined with Figure 1 and Figure 2 As shown, a water outlet is provided on the side wall of the temporary storage tank 1. This outlet is connected to the filter tank 3 via a water supply pipe, ensuring that rainwater in the temporary storage tank 1 can smoothly enter the filter tank 3 for filtration and purification. An electronic valve 14 is installed on the water supply pipe, which can adjust the flow rate of rainwater entering the filter tank 3.

[0051] Combination Figure 1 and Figure 2As shown, a weighing tray 12 is installed at the bottom of the temporary storage box 1, which can monitor the weight of rainwater inside the temporary storage box 1 in real time. Simultaneously, a support base 11 is installed at the bottom of the weighing tray 12. The support base 11 enhances the stability and load-bearing capacity of the entire device, ensuring that the device remains stable during prolonged use and large-scale rainwater collection, preventing tipping or damage. Furthermore, the support base 11 is made of anti-slip material, increasing friction with the ground and ensuring the stability and safety of the device even in windy and rainy weather.

[0052] Combination Figure 1 and Figure 2 As shown, a controller 13 is mounted on the support base 11. The controller 13 is connected to the weighing tray 12 and the electronic valve 14 via signal cables. The weighing tray 12 transmits weight information to the controller 13, which automatically adjusts the opening degree of the electronic valve 14 based on the received weight information and other relevant parameters, such as rainfall and the working status of the filter box 3, thereby precisely controlling the flow rate of rainwater entering the filter box 3. This design not only improves the automation level of rainwater collection and utilization but also effectively avoids resource waste or low treatment efficiency caused by excessive or insufficient rainwater.

[0053] Combination Figures 4 to 6 As shown, the filter box 3 is equipped with filter plates 322 and other filtration structures inside, which can effectively filter and purify the rainwater entering the filter box 3.

[0054] Combination Figure 7 and Figure 8 As shown, the filter box 3 has an upper pressure plate 321 and a lower pressure plate 323 horizontally arranged inside. The upper pressure plate 321 is located directly above the lower pressure plate 323. Both the upper and lower pressure plates 321 and 323 have through holes at corresponding positions, allowing rainwater to flow downwards. A filter plate 322 is installed between the upper and lower pressure plates 321 and 323. This filter plate 322 has a multi-layer structure, including a coarse filter layer, a fine filter layer, and an activated carbon layer, which can filter rainwater step by step, effectively removing impurities, particulate matter, and harmful substances from the rainwater, thus improving the purification effect. Furthermore, the filter plate 322 is detachable, facilitating regular cleaning or replacement by staff to ensure the continuous and efficient operation of the filter box 3.

[0055] Combination Figure 7 and Figure 8 The filter plate 322 has a first rack 324 on both sides of the top. The filter box 3 also has a first drive motor 325 inside. The cylinder end of the first drive motor 325 is connected to the inner wall of the filter box 3, and the output end of the first drive motor 325 is connected to the middle position of the first gear 326. The first gear 326 and the first rack 324 mesh with each other.

[0056] This invention uses a first drive motor 325 to power a first gear 326, which in turn drives a first rack 324 to move, thereby moving the filter plate 322 between the upper pressure plate 321 and the lower pressure plate 323. This design allows the filter plate 322 to move easily horizontally, facilitating cleaning or replacement by staff, ensuring the device is in optimal working condition, and guaranteeing effective rainwater purification.

[0057] Combination Figure 5 and Figure 6 As shown, a grid 31 is provided inside the filter box 3 and above the upper pressure plate 321. The grid 31 can perform preliminary filtration of rainwater entering the filter box 3, remove larger impurities and particles, protect the filter plate 322 from damage, and relatively extend the service life of the filter plate 322.

[0058] Combination Figure 9 and Figure 10 As shown, an upper baffle 331 and a lower baffle 332 are provided inside the filter box 3 and below the lower pressure plate 323. Both the upper baffle 331 and the lower baffle 332 have multiple through holes, so that the rainwater filtered by the filter plate 322 can flow smoothly downward.

[0059] The bottom of the lower baffle 332 is provided with a second rack 335, and the inside of the filter box 3 is also provided with a second drive motor 333. The cylinder end of the second drive motor 333 is connected to the inner wall of the filter box 3, and the output end of the second drive motor 333 is connected to the middle position of the second gear 334. The second gear 334 meshes with the second rack 335.

[0060] This invention utilizes a second drive motor 333 to power a second gear 334, which in turn moves a second rack 335 and a lower baffle 332. This allows adjustment of the position of the lower baffle 332 relative to the upper baffle 331, enabling the selection of the number of open holes and thus controlling the flow rate and volume of rainwater to meet rainwater treatment needs under different conditions. This design not only enhances the adaptability of the device but also ensures that the device maintains optimal operating conditions under varying rainfall amounts and treatment requirements.

[0061] Combination Figure 1 As shown, the water storage tank 4 is connected to the outlet of the filter tank 3 and is used to store the filtered and purified rainwater. The outlet of the water storage tank 4 is connected to the inlet of the water pump 5, and the outlet of the water pump 5 is connected to multiple water-using devices 6 so that the purified rainwater can be transported to each water-using device 6 for use.

[0062] Combination Figure 1As shown, the water storage tank 4 is made of high-strength, corrosion-resistant materials, has a large storage capacity and good insulation performance, ensuring that the purified rainwater will not deteriorate or become contaminated during long-term storage. The water pump 5 is a high-performance, low-noise pump that can provide stable water flow and pressure, ensuring that the purified rainwater can be smoothly delivered to various water-using devices 6.

[0063] Combination Figure 1 As shown, the top of the water storage tank 4 has a feed inlet. This inlet design allows users to easily add purifying agents or other chemical agents to the tank to further enhance the rainwater purification effect. In practical applications, users can select appropriate purifying agents to add based on the rainwater quality and treatment needs, thereby ensuring the safety and stability of the output water quality. A sealing cap is also provided at the feed inlet to prevent impurities and contaminants from entering the water storage tank 4, ensuring water quality safety.

[0064] Combination Figures 1 to 10 As shown, this utility model proposes a rainwater harvesting and utilization device for sponge cities. By adding an inverted umbrella-shaped rainwater collection unit 2 to the top of the temporary storage tank 1, the rainwater collection speed can be effectively improved. The rainwater is initially stored in the temporary storage tank 1, then filtered and purified by the filter tank 3, and finally the purified rainwater is transported to various water-using devices 6 by the water pump 5, realizing the effective utilization of rainwater. This utility model uses structural components such as the grid 31 and filter plate 322 added in the filter tank 3 to perform multi-stage filtration of rainwater, effectively improving the purification effect of rainwater and ensuring that the output water quality meets the usage requirements. At the same time, the filter plate 322 is detachable. The first drive motor 325 provides power to drive the filter plate 322 to move laterally, which is convenient for staff to clean or replace regularly, ensuring the continuous and efficient operation of the filter tank.

[0065] This utility model has a high degree of intelligence. By setting a weighing tray 12 at the bottom of the temporary storage box 1, the weight of rainwater in the temporary storage box 1 can be monitored in real time, which makes it convenient for staff to understand the rainwater collection situation in a timely manner. The opening degree of the electronic valve 14 is automatically adjusted according to the rainfall and the amount of water in the temporary storage box, thereby controlling the flow rate of rainwater entering the filter box 3, improving the efficiency of rainwater collection and utilization, and has high practicality.

[0066] Of course, the above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
