At the same time, the system is designed with multiple low-maintenance structures: the filter screen of the purification guide mechanism is quick-release type; the rainwater guide and discharge module can be integrally lifted to the ground through the sliding cooperation of the pull-out circular frame and the pull-out sliding groove, so that the guide and discharge rain chain and related components can be cleaned, realizing "maintenance without going down the well", and greatly improving the safety and convenience of operation. In addition, the backwashing module can periodically flush the filter purification wall to maintain its permeability. This all-round maintenance design effectively reduces the operating cost of the whole life cycle, achieves efficient recycling of rainwater resources, saves energy and protects the environment, and has significant benefits. The purified rainwater is stored in the storage cavity and recycled through the water resource utilization mechanism. The pressurized water supply line can be directly connected to the garden sprinkler system, and the quick connector of the water supply line can supply water to the watering truck. This design converts the originally directly discharged rainwater into a stable alternative water source for municipal purposes such as urban greening and road watering, directly reducing the consumption of tap water, realizing the recycling of water resources at the municipal scale, and having significant water-saving, environmental and economic benefits.

DETAILED DESCRIPTION
[0029] REFERENCE Figures 1 to 13 As shown in the drawings, a municipal road accumulated water prevention rainwater guide and drainage and purification utilization device comprises a guide and drainage channel mechanism 200 arranged on one side of a municipal road 100 for collecting surface rainwater; A guide and drainage well pipe 400 is arranged on one side of the guide and drainage channel mechanism 200 and communicates with the guide and drainage channel mechanism 200; An overflow guide and drainage assembly 600 is arranged at the bottom of the guide and drainage well pipe 400 for realizing rainwater overflow drainage, in particular for preventing well water level from being too high to flow back to the road surface when the rainfall is too large; The purification water storage mechanism 800 is buried below the ground, and is used for filtering and storing the introduced rainwater. The purification flow guide mechanism is used for connecting the drainage well pipe 400 and the purification water storage mechanism 800, and introducing the middle-layer rainwater after preliminary precipitation into the purification water storage mechanism 800. The water resource utilization mechanism 900 is in communication with the purification water storage mechanism 800, and is used for reusing the purified rainwater, and realizing resource utilization.
[0030] Further preferably, the drainage channel mechanism 200 comprises: The drainage channel assembly 210 is arranged at one side of the municipal road 100, and is used for preliminarily collecting the road surface water and guiding the rainwater to the drainage round channel 300. The curb drainage assembly 220 is arranged on the road curb, and is cooperated with the drainage channel assembly 210, and realizes the centralized drainage and foreign matter blocking of the rainwater through the water accumulation groove 222 and the containing turning groove 223. The drainage round channel 300 is arranged on the ground, and is located directly below the curb drainage assembly 220, and the drainage well pipe 400 is located directly below the drainage round channel 300, so as to ensure that the rainwater is smoothly transferred to the underground drainage system. The rainwater drainage module 500 is arranged in the drainage round channel 300 and the drainage well pipe 400, and is used for collecting the rainwater collected by the drainage channel assembly 210 and introducing the rainwater into the drainage well pipe 400, and preliminarily filtering the rainwater and blocking the larger particle garbage.
[0031] Further, the drainage channel assembly 210 comprises: The rainwater guide groove 211 is arranged at one side of the municipal road 100, and a flow guide inclined angle in communication with the drainage round channel 300 is arranged at the bottom surface of the rainwater guide groove 211; and the bottom of the rainwater guide groove 211 is provided with a 1-5% bidirectional slope, so that the initial rainwater is self-flowed into the drainage round channel 300 by gravity without pump, and the instantaneous water depth is reduced. The rainwater cover groove 212 is arranged directly above the rainwater guide groove 211. The plurality of drainage cover plates 213 are arranged on the rainwater guide groove. The rotating base 214 is arranged at the road curb. The rotating cover plate 215 is cooperated with the drainage cover plate 213. The rotating unit 216 is arranged on the rotating base 214, and is cooperated with the rotating cover plate 215.
[0032] Further, the curb drainage assembly 220 comprises: A drainage curbstone 221 is arranged on the road curbstone and located directly above the rotating base 214. A water accumulation drainage groove 222 is formed in the side of the drainage curbstone 221 facing the rainwater guide groove 211 and is connected to the guide drainage groove 300. A containing rotation groove 223 is formed in the side of the drainage curbstone 221 facing the rainwater guide groove 211 and cooperates with the rotating cover plate 215. A water accumulation cover groove 224 is formed in the top of the drainage curbstone 221 and cooperates with the rainwater guide and drainage module 500. A water accumulation blocking sill 225 is arranged on the water accumulation drainage groove 222 and cooperates with the purification water storage mechanism 800.
[0033] The water accumulation blocking sill 225 cooperates with the rotating cover plate 215 to block larger garbage such as branches, bricks, baffles and sundries to the outside.
[0034] Specifically, the rotating cover plate 215 cooperates with the guide cover plate 213 and rotates on the rotating base 214 through the rotating unit 216. The rotating unit 216 includes a rotating shaft assembly for supporting the rotating cover plate 215 and a rotating drive mechanism. The rotating unit 216 is one of manual operation, trigger automatic operation or semi-automatic operation. The manual operation drives the rotating shaft to rotate through a handle or a wrench to open or close the rotating cover plate 215. The trigger automatic operation activates the rotating drive mechanism to automatically rotate the rotating cover plate 215 through a water level or pressure trigger device. The semi-automatic operation rotates the rotating cover plate 215 through a trigger spring or gravity mechanism by manually releasing a locking device.
[0035] The rotating unit 216 further includes a spring mechanism arranged on the rotating shaft. The spring mechanism automatically provides a rotating force when the locking device is manually released, so that the rotating cover plate 215 is smoothly opened, and is reset by gravity or spring when closed.
[0036] In addition, the trigger condition of the trigger automatic operation includes that the water level reaches a set threshold or the water pressure reaches a set threshold. The rotating unit 216 is provided with a sensor to detect the water level or pressure and drive the rotating cover plate 215 to open through a mechanical link or a micro driver when triggered. The working logic is that it is closed to intercept large floating objects on the road surface at ordinary times, and is opened or the opening degree is increased to accelerate the drainage of road surface water during heavy rain. Further preferably, the rainwater guide and drainage module 500 includes: A water accumulation cover plate 510 is arranged in the water accumulation cover groove 224 and a stable connecting piece 530 is arranged at the bottom end of the water accumulation cover plate 510. A first connecting frame assembly 540 is located directly below the drainage curbstone 221 and is in the same plane as the guide cover plate 213. The second connecting bracket assembly 550 is located directly below the first connecting bracket assembly 540 and is in the same plane as the bottom end of the rainwater guide groove 211. The preliminary filtering assembly 560 is arranged in the guide circular groove 300. The rainwater guide chain 570 is connected to the stable connecting member 530 at the top end and is fixedly connected to the overflow guide assembly 600 at the bottom end, and sequentially penetrates the first connecting bracket assembly 540, the second connecting bracket assembly 550, and the preliminary filtering assembly 560.
[0037] The rainwater guide module 500 is located in the guide circular groove 300 and the guide well pipe 400, and through the combination of multiple components, the collected rainwater is concentrated, filtered, and blocked, and is finally guided into the underground guide well pipe 400. The design ensures that the rainwater can be smoothly discharged when the rainfall is large or the road waterlogging is serious, and at the same time, prevents garbage from entering the downstream pipeline.
[0038] The core function of the rainwater guide chain 570 is that after the rainwater is collected from the center of the water accumulation cover plate 510 and falls to the top end of the rainwater guide chain 570, it is no longer directly impacted on the well bottom in the form of a large flow column, but is attached to the surface of the chain link to form a water film by the surface tension and gravity of the water, and slowly slides down along the chain body spiral. This greatly reduces the water flow speed, reduces the erosion of the well bottom structure, and promotes the natural sedimentation of heavier particles in the water. In addition, the irregular structure of the chain link will produce micro-disturbance when the water flows, which helps to prevent impurities from adhering and accumulating on the chain body, and has a certain self-cleaning ability. At the same time, this disturbance can make the water flow have more contact with the air, achieving preliminary aeration. In addition, as a connecting structure, the upper water accumulation cover plate 510 and the bottom filtering cylinder 660 are connected as a whole, which is convenient for overall maintenance. Further, the first connecting bracket assembly 540 comprises: The connecting bracket ring seat 541 is provided with a connecting bracket through groove matched with the rainwater guide chain 570; The surrounding sleeve ring 542 is arranged on the connecting bracket ring seat 541 in a surrounding manner; A plurality of connecting supports 543 are uniformly arranged on the connecting bracket ring seat 541 along the circumferential direction of the connecting bracket ring seat 541 and are located in the surrounding ring groove of the surrounding sleeve ring 542; And a plurality of connecting chains 544, one end of which is connected with the connecting support 543, and the other end thereof is connected with the guide circular groove 300 through a screw rod; Further, the structure of the second connecting bracket assembly 550 is consistent with that of the first connecting bracket assembly 540; Specifically, the first and second continuous rack assemblies 540 and 550 are arranged vertically to form a stable "double bearing" support frame. The working principle is that the continuous rack through groove in the center of the continuous rack ring seat 541 provides a precise vertical channel for the rain chain guide 570, limiting its horizontal swing. The connecting chain 544 is anchored in the inner wall of the guide circular groove 300 by a screw rod, firmly suspending the entire continuous rack assembly at a predetermined position. Its core function is to ensure that the rain chain guide 570 is always in a state of tension and centering, avoiding collisions and entanglements with the well wall or other components due to water flow impact or its own weight, and ensuring the stability of its flow guiding function. The surrounding sleeve ring 542 plays a protective role, preventing foreign objects from getting stuck in the moving parts.
[0039] Further, the preliminary filtering assembly 560 includes a filter cylinder 561, and the top end of the filter cylinder 561 is provided with a fall prevention ring plate 562 matched with the guide circular groove 300; and the bottom end of the filter cylinder 561 is provided with a filter through groove 563 matched with the rain chain guide 570.
[0040] The preliminary filtering assembly 560 filter cylinder (561) is located at the bottom of the guide circular groove 300, which is the last rough filtration barrier before the rainwater enters the guide well pipe 400. Specifically, the filter cylinder 561 wall is provided with fine pores that can intercept medium and small particle solids such as sand and small organic matter passing through the accumulated water cover plate 510. The fall prevention ring plate 562 is crucial, as it rests on the mouth of the guide circular groove 300, preventing the filter cylinder 561 from falling into the well pipe due to water flow impact or chain traction, while facilitating manual lifting from the ground for cleaning or replacement.
[0041] Further preferably, the accumulated water cover plate 510 includes: An accumulated water ring plate 511 is arranged directly below the drainage curb 221, and the accumulated water ring plate 511 is provided with an accumulated water ring seat 512 matched with the accumulated water cover groove 224; A closed cover plate 520 is arranged at the accumulated water ring seat 512, and the closed cover plate 520 is provided with a water permeation groove; Further, the closed cover plate 520 includes: A connecting circular plate 521 is provided with the water permeation groove, and the connecting circular plate 521 is provided with a connecting screw matched with the accumulated water ring seat 512; A connecting circular frame 522 is arranged at the center of the connecting circular plate 521, and the stable connecting piece 530 is arranged on the connecting circular frame 522; A plurality of guide inclined plates 523 are arranged at the bottom end of the connecting circular plate 521 along the circumferential direction of the connecting circular frame 522, and one end of the guide inclined plates 523 is connected with the connecting circular frame 522 and is arranged corresponding to the water permeation groove.
[0042] The primary function of the water-permeable groove on the closure cover plate 520 is to intercept large floating objects such as plastic bags and large leaves to prevent them from directly entering the system and causing blockage. The guide inclined plate 523 is one of the key innovations. Its working principle is to change the free-fall trajectory of the water flow. After the rainwater permeates through the water-permeable groove, it will naturally drip onto the inclined surface of the guide inclined plate 523. Using the wall effect of fluid mechanics and gravity, the water flow will converge along the surface of the inclined plate and be directed to the central connecting circular frame 522 area. This allows the originally scattered water flow to be concentrated, creating conditions for efficient water diversion of the "rain chain 570" and avoiding the disorderly impact and splashing of the water flow on the well wall.
[0043] Further, the stable connecting piece 530 includes a pull-out circular frame 531 arranged on the connecting circular frame 522, and a pull-out sliding groove 532 is arranged on the pull-out circular frame 531.
