DETAILED DESCRIPTION

[0040] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] With reference to Figure 1 , Figure 2 and Figure 4 , the present application provides an embodiment: a road drainage structure, comprising a shell 1, the shell 1 is closed, effectively preventing foreign matter from entering the inside of the drainage device, ensuring the stable operation of each mechanism, providing reliable external protection for the overall drainage structure, the top of the shell 1 is fixedly connected with a processing mechanism 2, the processing mechanism 2 can perform multi-level processing on rainwater, starting from the road surface layer 201, efficiently allowing the rainwater to penetrate and be purified, greatly improving the water quality, the bottom of the processing mechanism 2 is slidingly connected with a water conveying mechanism 3, the water conveying mechanism 3 can smoothly convey the processed rainwater to a designated location, and the sliding connection mode of the water conveying mechanism 3 and the processing mechanism 2 facilitates disassembly and maintenance when necessary.

[0042] The outer side of the water conveying mechanism 3 is slidingly connected with the docking mechanism 6, which makes the pipeline connection of the water conveying mechanism 3 more convenient. Through the cooperation of the limiting ring one 601 and the limiting ring two 602, the installation and disassembly of the pipeline can be easily realized, and the sealing performance of the connection can also be ensured. The outer side of the water conveying mechanism 3 is fixedly connected with the connecting mechanism 4, which plays a role in stably connecting the automatic detection device 5, ensuring that the automatic detection device 5 is stably installed on the outer side of the water conveying mechanism 3, and then continuously and accurately monitoring the water conveying situation. The end of the connecting mechanism 4 away from the processing mechanism 2 is fixedly connected with the automatic detection device 5. The automatic detection device 5 can monitor the operating condition of the water conveying mechanism 3 in real time. Once an abnormality occurs, it can be fed back in time to ensure the normal operation of the drainage device. The inside of the shell 1 is provided with a personnel access port 7, which facilitates the entry of workers into the inside of the shell 1. When the water conveying mechanism 3 or other internal components have problems, maintenance and repair can be carried out through this access port.

[0043] Specifically, the road drainage structure is cooperated by multiple key parts. The shell 1 is in a closed state, which can effectively block foreign matter from the outside, providing reliable protection for the stable operation of each mechanism of the drainage device. The processing mechanism 2 connected at the top can efficiently infiltrate and purify rainwater through multiple layers of structures such as the pavement layer 201, improving water quality. The water conveying mechanism 3 is slidingly connected to the bottom of the processing mechanism 2, which not only smoothly conveys the treated rainwater to the designated location, but also facilitates disassembly and maintenance due to the sliding connection. The docking mechanism 6 on the outer side of the water conveying mechanism 3 uses limiting ring one 601 and limiting ring two 602 to make pipeline connection convenient and ensure good sealing at the connection. The connecting mechanism 4 on the outer side of the water conveying mechanism 3 stably connects the automatic detection device 5, enabling it to be stably installed on the outer side of the water conveying mechanism 3 and to monitor the water conveying situation in real time and accurately. Once an abnormality occurs, it can be fed back in time. The personnel access port 7 provided in the inside of the shell 1 provides convenience for workers to enter the inside for repair of the water conveying mechanism 3 and other components, ensuring that the drainage device is always in a normal operating state.

[0044] The connecting mechanism 4 includes a fixed column 401, which provides a stable support frame for the entire connecting mechanism 4, ensuring the stability and reliability of the connection, so that components such as the connecting column 404 can work normally inside. The inside of the fixed column 401 is provided with a clamping groove 403, which is the moving track and positioning point of the limiting block 405. The precise design of the clamping groove 403 ensures that the limiting block 405 can be accurately clamped in, realizing the stable connection of the automatic detection device 5 and the water conveying mechanism 3. The inside of the fixed column 401 is slidingly connected with the connecting column 404, which smoothly slides inside the fixed column 401, providing convenience for the disassembly and installation operation of the automatic detection device 5, enabling efficient maintenance and replacement work to be carried out.

[0045] The outer side of the connecting column 404 is fixedly connected with a limiting block 405. The limiting block 405 is driven by the connecting column 404 and is firmly fixed on the water conveying mechanism 3 by cooperating with the clamping groove 403, so as to prevent the device from loosening or shifting during operation. The inner part of the fixing column 401 is fixedly connected with a jacking assembly 402. When the automatic detection device 5 is installed, the jacking assembly 402 pushes the jacking plate 4023 by using the elastic force of the spring 4022, so that the limiting block 405 can be tightly clamped at the corner of the clamping groove 403, further enhancing the tightness and stability of the connection.

[0046] Specifically, the fixing column 401 builds a stable support frame, so that the connecting column 404 and other components can operate without worry. The clamping groove 403 in the inner part is the key to providing a track and positioning for the limiting block 405, ensuring that it is accurately clamped and stably connected with the water conveying mechanism 3. The connecting column 404 can slide smoothly in the fixing column 401, greatly facilitating the disassembly and installation of the automatic detection device 5 and improving the maintenance efficiency. The limiting block 405 on the outer side of the connecting column 404 moves with it and cooperates with the clamping groove 403 to prevent the device from loosening and shifting. When installed, the jacking assembly 402 pushes the jacking plate 4023 by the elastic force of the spring 4022, helping the limiting block 405 to be tightly clamped at the corner of the clamping groove 403, further strengthening the tightness and stability of the connection, and comprehensively ensuring the reliable operation of the automatic detection device 5.

[0047] The jacking assembly 402 includes a fixed plate 4021, which provides a stable base support for the jacking assembly 402 and is tightly fixed in the inner part of the fixing column 401, ensuring that the entire jacking assembly 402 will not shift during operation and providing a reliable basis for the operation of the spring 4022 and the jacking plate 4023. The outer side of the fixed plate 4021 is fixedly connected to the inner part of the fixing column 401. This fixing method makes the fixed plate 4021 and the fixing column 401 form a stable whole, ensuring that the jacking assembly 402 can always maintain the correct position when the connecting column 404 slides and other operations, effectively playing its role. One side of the fixed plate 4021 is fixedly connected with a spring 4022, which is the core elastic element of the jacking assembly 402 and has the key functions of storing energy and releasing energy. When the automatic detection device 5 is installed, the spring 4022 is compressed by external force to store elastic potential energy, and at the appropriate time, the spring 4022 releases energy to provide a pushing force for the jacking plate 4023.

[0048] The other end of the spring 4022 is fixedly connected with a jacking plate 4023, which is driven by the spring 4022 and can convert the energy released by the spring 4022 into the driving force for pushing the connecting column 404. The design enables the jacking plate 4023 to accurately push the limiting block 405 to a specific position of the clamping groove 403 when the automatic detection device 5 is installed, so as to realize close connection. The outer side of the jacking plate 4023 is slidingly connected to the inside of the fixed column 401. The sliding of the jacking plate 4023 in the fixed column 401 ensures that it can move along a specific trajectory, accurately transmit the force of the spring 4022 to the connecting column 404, and remain stable during the sliding process without deviation or jamming, thereby ensuring the smoothness of the entire connection process. The end of the jacking plate 4023 away from the spring 4022 is slidingly connected to the inside of the connecting column 404. This connection forms an effective force transmission path between the jacking plate 4023 and the connecting column 404. When the spring 4022 releases energy to push the jacking plate 4023, the jacking plate 4023 can accurately apply this force to the connecting column 404, thereby moving the limiting block 405 to the corner of the clamping groove 403, realizing stable connection of the automatic detection device 5.

[0049] Specifically, the fixed plate 4021 is firmly fixed to the inside of the fixed column 401 to provide stable support for the entire jacking assembly 402, ensuring that the jacking assembly 402 is stable in position during the sliding of the connecting column 404 and other operations, and plays its due role. The spring 4022 is the core elastic element. When the automatic detection device 5 is installed, it is compressed by external force to store elastic potential energy and releases energy at the right time to provide a pushing force for the jacking plate 4023. The jacking plate 4023, driven by the spring 4022, converts the energy of the spring 4022 into the driving force for pushing the connecting column 404, accurately pushes the limiting block 405 into a specific position of the clamping groove 403, and slides on the outside of the fixed column 401 along a specific trajectory to stably move and accurately transmit the force of the spring 4022, avoiding deviation and jamming to ensure smooth connection. The other end of the jacking plate 4023 is slidingly connected to the inside of the connecting column 404 to form an effective force transmission path, so that the force of the spring 4022 is accurately applied to the connecting column 404 to move the limiting block 405 to the corner of the clamping groove 403, realizing stable connection of the automatic detection device 5.

[0050] The processing mechanism 2 comprises a road surface layer 201 capable of rapidly guiding rainwater infiltration, greatly reducing the formation of road surface water, effectively ensuring the safe passage of vehicles and pedestrians in rainy days, and the bottom of the road surface layer 201 is fixedly connected with a permeation layer 202 which can preliminarily filter rainwater, intercept larger particle impurities, and simultaneously uniformly disperse rainwater, laying a good foundation for subsequent deep purification, the bottom of the permeation layer 202 is fixedly connected with a filter layer 203 which further purifies water quality, removes residual fine impurities and part of pollutants in rainwater, and improves rainwater cleanliness, the bottom of the filter layer 203 is fixedly connected with a water storage layer 204 which can temporarily store rainwater treated by multiple layers, plays a buffering role, and ensures that rainwater can flow into the next layer stably according to requirements, and the bottom of the water storage layer 204 is fixedly connected to the top of the shell 1, and this connection mode stably places the water storage layer 204 on the shell 1, ensures the continuity and stability of the rainwater treatment and transmission process, and enables the drainage device to operate reliably.

[0051] Specifically, the road surface layer 201 can rapidly guide rainwater infiltration, reduce road surface water, and ensure traffic safety, the permeation layer 202 below can preliminarily filter rainwater, intercept larger particle impurities, and uniformly disperse rainwater, preparing for subsequent purification, the filter layer 203 further purifies water quality, removes fine impurities and part of pollutants, and improves rainwater cleanliness, rainwater treated by multiple layers flows into the water storage layer 204 which plays a buffering role, enabling rainwater to flow into the next layer stably according to requirements, the bottom of the water storage layer 204 is fixed to the top of the shell 1, the stable connection mode ensures the continuity and stability of the rainwater treatment and transmission process, and enables the entire drainage device to operate reliably and efficiently.

[0052] The water conveying mechanism 3 comprises a drainage pipeline one 301 responsible for transporting treated rainwater over a long distance, and can efficiently and rapidly transport a large amount of rainwater to a designated location by virtue of its large pipe diameter and smooth inner wall design, ensuring the timeliness of drainage, and the two ends of the drainage pipeline one 301 are both slidably connected with a drainage pipeline two 303, and this sliding connection mode greatly improves the flexibility of the water conveying mechanism 3, when it is necessary to repair, replace or adjust the pipeline layout according to actual drainage requirements, the drainage pipeline two 303 can be easily detached from the drainage pipeline one 301, which is convenient to operate and does not affect the normal operation of the entire drainage device;

[0053] The top of the second drainage pipeline 303 is fixedly connected with the water inlet pipe 302, which can accurately guide the rainwater in the water storage layer 204 into the second drainage pipeline 303. The connection position and angle are carefully designed to ensure that the rainwater can smoothly flow into the pipeline at a suitable flow rate and flow volume, avoiding affecting the drainage efficiency due to excessive or insufficient water flow. The outer side of the water inlet pipe 302 is slidingly connected to the inside of the water storage layer 204. This sliding connection allows the water inlet pipe 302 to not only stably maintain its position in the water storage layer 204, but also to be slightly adjusted when necessary, such as when the water storage layer 204 is slightly deformed due to external factors. The water inlet pipe 302 can still maintain a good connection state, ensuring that the rainwater continuously and stably flows from the water storage layer 204 to the water conveying mechanism 3, maintaining the stable operation of the drainage device.

[0054] Specifically, the first drainage pipeline 301 has a large diameter and smooth inner wall, allowing it to transport a large amount of treated rainwater over a long distance quickly, ensuring timely drainage. Its two ends are slidingly connected to the second drainage pipeline 303. This design improves the flexibility of the water conveying mechanism 3, facilitating local pipeline maintenance, replacement, or layout adjustment without affecting overall drainage. The water inlet pipe 302 at the top of the second drainage pipeline 303 is designed with a clever connection position and angle, allowing it to accurately guide the rainwater from the water storage layer 204 into the second drainage pipeline 303, ensuring smooth flow at a suitable flow rate and flow volume, avoiding affecting the drainage efficiency. The outer side of the water inlet pipe 302 is slidingly connected to the water storage layer 204, allowing it to not only stably maintain its position, but also to be slightly adjusted when the water storage layer 204 is slightly deformed, maintaining a good connection and ensuring that the rainwater continuously and stably flows to the water conveying mechanism 3, maintaining the stable operation of the drainage device.

[0055] Referring to Figures 1 to 3 The docking mechanism 6 includes a limiting ring one 601, which is an important component for ensuring stable pipeline connection. Through clever structural design, it cooperates with other components to provide reliable support and constraints for pipeline connection. The outer side of the limiting ring one 601 is fixedly connected with a connecting block 605, which tightly connects the limiting ring one 601 and the limiting ring two 602, forming an organic whole. This ensures that the two limiting rings can work together and play a role in pipeline docking and subsequent use. The other end of the connecting block 605 is fixedly connected with the limiting ring two 602, which cooperates with the limiting ring one 601 to position and fix the first drainage pipeline 301 and the second drainage pipeline 303, ensuring the accuracy and stability of pipeline connection. The inside of the limiting ring two 602 is provided with two sliding grooves 604, which provide a precise installation track for the first drainage pipeline 301, allowing it to smoothly slide in and achieve quick and accurate docking, greatly improving installation efficiency.

[0056] The outer side of the drain pipe 301 is slidingly connected in the inner side of the sliding groove 604. This sliding connection method not only facilitates installation, but also enables the drain pipe 301 to be closely attached to the limiting ring 602 after installation, further enhancing the firmness of the connection, effectively preventing the pipe from being displaced under the impact of water flow. The inner side of the limiting ring 601 is fixedly connected with the sealing ring 603, which is the key to ensuring the sealing of the pipe connection. When the limiting ring 601 is flipped and cooperates with the limiting ring 602 to complete the pipe butt joint, the sealing ring 603 can be closely attached to the outer side of the drain pipe 301, effectively preventing rainwater leakage and ensuring good sealing of the drainage device. The outer side of the sealing ring 603 is slidingly connected to the outer side of the drain pipe 301. This design enables the sealing ring 603 to be flexibly slid along the outer side of the drain pipe 301 under the drive of the limiting ring 601, accurately reaching the pipe butt joint and achieving seamless sealing, greatly improving the waterproof performance of the drainage device and ensuring smooth drainage work.

[0057] Specifically, the limiting ring 601 provides support and constraint for pipe connection in cooperation with other components through ingenious structure. The connecting block 605 closely connects the limiting ring 601 and the limiting ring 602, so that they can work together during pipe butt joint and use. The limiting ring 602 cooperates with the limiting ring 601 to accurately position and fix the drain pipe 301 and the drain pipe 302, ensuring accurate and stable connection. The sliding groove 604 in the limiting ring 602 provides an installation track for the drain pipe 301, facilitating its quick and accurate sliding into the track and improving installation efficiency. After installation, the drain pipe 301 can be closely attached to enhance the firmness of the connection and prevent pipe displacement. The sealing ring 603 is crucial. When the limiting ring 601 is flipped and cooperates with the limiting ring 602 to complete the butt joint, it can be closely attached to the outer side of the drain pipe 301, effectively preventing rainwater leakage. It can be flexibly slid to the butt joint under the drive of the limiting ring 601, achieving seamless sealing and improving the waterproof performance of the drainage device to facilitate smooth drainage work.

[0058] Working principle: when the heavy rain, rain will pass through the road layer 201 and road layer 201 is made of water permeable paving materials, allowing rainwater to quickly infiltrate the lower layer, the lower layer of road layer 201 is the infiltration layer 202 and the infiltration layer 202 is composed of gravel or other porous materials, can be used for preliminary filtration and dispersion of rainwater, when the rainwater passes through the infiltration layer 202 will reach the filter layer 203 and the filter layer 203 is composed of fine sand or activated carbon and other materials, can further purify water quality, finally the rainwater will enter the inside of the water storage layer 204, the water storage layer 204 is used for temporarily storing rainwater after processing by the previous layer, at this time the rainwater in the water storage layer 204 will enter the inside of the drain pipe one 301 and the drain pipe two 303 through three water inlet pipes 302, at this time the rainwater can be transmitted through the drain pipe one 301, and when the drain pipe one 301 or the drain pipe two 303 needs to be repaired or replaced, the staff can enter the inside of the shell 1 through the personnel access 7 through a specific position, at this time the bolt which limits the limiting ring one 601 and the limiting ring two 602 is rotated, so that the limitation of the limiting ring one 601 and the limiting ring two 602 is cancelled, at this time the limiting ring one 601 can be turned over, at this time the drain pipe two 303 can be taken out from the inside of the sliding groove 604, so as to repair or replace it, when it is needed to install the drain pipe two 303 back, the drain pipe two 303 can be placed in the inside of the sliding groove 604, the limiting ring one 601 is turned back, and the bolt is rotated tightly.

[0059] When the automatic detection device 5 needs to be replaced, the automatic detection device 5 can be rotated, so that the automatic detection device 5 drives the connecting column 404, and the connecting column 404 is connected with a plurality of limiting blocks 405 on the outside, so that the connecting column 404 drives the limiting blocks 405, and the limiting blocks 405 are separated from the inside of the clamping groove 403, and then the automatic detection device 5 can be disassembled from the outside of the second drain pipe 303 or the first drain pipe 301. When a new automatic detection device 5 needs to be installed, the outside of the limiting block 405 is aligned with the inside of the clamping groove 403 in the inside of the fixed column 401, and the limiting block 405 is slid into the clamping groove 403, so that the pressing plate 4023 is pressed, and when the connecting column 404 cannot slide in the inside of the fixed column 401, the connecting column 404 is rotated, so that the limiting block 405 slides to the corner of the clamping groove 403, and then the connecting column 404 is released, so that the compressed spring 4022 releases the pressure to provide the elastic force to the connecting column 404, and the connecting column 404 is driven outward, so that the connecting column 404 drives the limiting block 405, and the limiting block 405 slides at the corner of the clamping groove 403, so that the limiting block 405 is connected more tightly in the inside of the clamping groove 403.
