Description

Technical Field

[0001] This utility model relates to the field of urban ecological engineering technology, specifically to a sponge city garden ecological purification device. Background Technology

[0002] Sponge cities absorb, store, infiltrate, and purify rainwater during rainfall, and release and utilize the stored water when needed, enabling rainwater to migrate freely within the city and improving the efficiency of rainwater utilization. In this process, plants are an important component of sponge city construction. Traditional plant planting devices do not have the functions of absorbing, storing, and purifying water, and therefore fail to fully realize the efficient utilization of rainwater. For this reason, we provide plant planting devices for sponge cities.

[0003] For example, the device, named "Sponge City Water Storage Inlet Filtration Device" under announcement number CN211447205U, includes a water storage well, connectors, a filter assembly, and a propeller. Two sets of connectors are provided, each set positioned on either side of the top of the water storage well. Each set of connectors has a first mounting groove and a second mounting groove at its top and bottom, respectively. The drainage cover extends to the first mounting groove on both sides.

[0004] During the use of the above-mentioned device, the filter plates are difficult to disassemble, which is time-consuming and laborious, increasing the difficulty and time consumption of maintenance. The filter plates will accumulate a large amount of pollutants, reducing filtration efficiency and affecting the effect of ecological restoration. Therefore, we propose a sponge city garden ecological purification device to solve the problems mentioned above. Utility Model Content

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This invention features a handle. Applying force to the handle moves the locking block, causing it to detach from the slot and thus releasing the filter screen from its fixation. Applying force to the filter screen allows for easy removal for maintenance. This process is convenient and easy to use, greatly improving the device's practicality. It enables rapid installation and maintenance of the filter screen, reducing maintenance difficulty and time. It overcomes the drawbacks of traditional devices where filter plate disassembly is cumbersome, time-consuming, and increases maintenance difficulty and time, leading to the accumulation of pollutants on the filter plate, reduced filtration efficiency, and negatively impacting ecological restoration.
