Description

Technical Field

[0001] This application relates to the field of drainage technology for municipal road construction, and in particular to a drainage system for municipal road construction. Background Technology

[0002] In municipal road construction, drainage devices are crucial for ensuring construction progress and road safety. Although existing drainage devices have improved their performance through various designs, significant shortcomings remain in practical applications. To address filter clogging, some drainage devices employ motor-driven cleaning brushes for automatic cleaning. For example, Chinese patent CN218264224U discloses an improved municipal road construction drainage device that uses a quick-connect mechanism for easy disassembly and assembly of the drainage cover and a motor-driven cleaning brush for cleaning the filter. However, this solution still has significant drawbacks in practical applications. The design of installing the motor inside the drainage cylinder exposes it to a harsh environment of high humidity and water accumulation for extended periods. Even with a waterproof motor, the motor and connected wiring will still age and corrode due to prolonged moisture. Damage to the insulation layer can lead not only to motor failure but also to electrical leakage, posing a serious threat to the lives of construction workers and pedestrians. Furthermore, the damp and confined space... The limited space in the drainage cylinder makes routine maintenance and line upkeep of the motor extremely difficult. Maintenance personnel must expend significant time and effort, sometimes even requiring the dismantling of parts of the device to complete the repairs, greatly increasing maintenance costs and technical complexity. In terms of energy consumption, the motor-driven cleaning method relies on a continuous power supply. In municipal road construction scenarios, numerous drainage devices are required to operate for extended periods, consuming substantial amounts of electricity. This not only increases construction costs but also contradicts the current development concepts of green environmental protection, energy conservation, and emission reduction, failing to meet the needs of sustainable development projects. The structural design of the drainage device also has shortcomings. Traditional drainage covers are mostly fixed with bolts. When cleaning the inside of the drainage cylinder, operators must use tools to disassemble each bolt individually, a cumbersome and time-consuming process. Frequent disassembly can cause thread wear, leading to a decrease in the seal between the drainage cover and the drainage cylinder, affecting the normal operation of the drainage device. Therefore, the existing technology has certain defects and deficiencies, necessitating design improvements. Summary of the Invention

[0009] Optionally, the cleaning mechanism includes an inner ring and a cleaning brush assembly. The inner ring is placed on top of the inner limiting ring.

[0010] Optionally, the filter screen is generally conical in shape, and the top of the filter screen is connected to the bottom of the cleaning mechanism.

[0011] Optionally, the drive mechanism includes an inner frame and a high-torque screw. The inner frame is fixedly installed on the inner side of the base ring.

[0014] In summary, this application includes the following beneficial technical effects: This drainage system uses the pressure of traffic participants as its power source. When vehicles drive over the buffer strip at intersections, the pressure is converted into the rotational power of the cleaning mechanism through the connecting components. This drives the cleaning brush to clean the conical filter screen, effectively removing dirt such as leaves and mud. After cleaning, a high-elasticity reset spring pushes the mechanism to reset, preparing it for the next cleaning. This system does not require electricity, avoiding problems such as leakage and aging of traditional electric devices in humid environments, significantly improving operational stability. At the same time, the automated cleaning mechanism reduces the frequency of filter clogging and extends the maintenance cycle. Compared with traditional devices, it greatly reduces manual maintenance costs and operational difficulty. This system organically integrates road safety protection and drainage functions, achieving both vehicle deceleration from speed bumps and efficient drainage. The road surface water guide channel and anti-skid groove work together to quickly divert rainwater. The conical filter screen, combined with the rotating cleaning brush, forms a dual anti-clogging mechanism. The anti-skid groove of the intersection buffer zone increases friction to prevent vehicles from slipping. The arc-shaped top design reduces impact vibration and water residue. The internal high-elasticity return spring has both return and buffer functions, protecting the internal structure and extending the service life of the equipment, thus comprehensively improving the safety and drainage efficiency of municipal road construction. This drainage system adopts a modular assembly structure, which greatly improves the convenience of maintenance. The inner ring and the inner limit ring are embedded and form a detachable connection. When maintenance is required, the operator does not need complicated tools. He only needs to pull the intersection buffer strip and the matching main sleeve out of the drainage channel to separate the drainage system from the road surface. Further disassembling the main sleeve allows for the quick removal of the inner ring and its top cleaning mechanism, drive mechanism and connecting components, enabling unobstructed cleaning and replacement of the filter screen. This design simplifies the cumbersome maintenance process of traditional drainage devices, greatly shortens maintenance time, and reduces the difficulty of manual operation. Whether it is daily inspection or deep cleaning, it can be completed efficiently, effectively ensuring the continuous and stable operation of the municipal road construction drainage system.

[0017] The following is in conjunction with the appendix Figures 1-10 This application will be described in further detail.

[0018] This application discloses a drainage system for municipal road construction. For example... Figures 1-10 As shown, the road surface 1 is included. A drainage channel 2 is provided in the middle of the road surface 1. Water leakage channels 3 are provided in a linear arrangement at equal intervals inside the drainage channel 2. Filter devices 6 are inserted inside the water leakage channels 3. Support columns 4 are fixedly installed on the top of the filter devices 6. Roadway buffer strips 5 are fixedly installed on the top of the support columns 4. A main drainage pipe 9 is buried at the bottom of the road surface 1. The input end of the main drainage pipe 9 is connected to the bottom of each water leakage channel 3. The filter device 6 includes a main sleeve 61, which is inserted into the drainage trough 3. The drainage trough 3 is cylindrical in shape. A sealing and limiting ring 62 is fixedly installed on the top of the main sleeve 61, covering the outside of the drainage trough 3. A filter assembly 63 is fixedly connected to the bottom of the main sleeve 61. An inner limiting ring 64 is fixedly installed in the middle of the main sleeve 61. A cleaning mechanism 65 is placed on the top of the inner limiting ring 64. A drive mechanism 66 is fixedly installed on the top of the cleaning mechanism 65. A connecting assembly 67 is fixedly installed on the top of the drive mechanism 66. The top of the connecting assembly 67 is connected to the bottom of the intersection buffer strip 5. When the municipal road construction drainage system is running, rainwater from the road surface 1 quickly flows into the central drainage trough 2 through the inclined guide channels 8 on both sides, and then flows into the filter device 6 through the equally spaced drainage channels 3. When a vehicle runs over the intersection buffer strip 5, the pressure is transmitted to the connecting assembly 67 through the support column 4, driving the connecting column 673 and the ten The lowering of the frame 671 and cross seat 672 causes the slip ring 656 to slide down along the inner wall of the main sleeve 61, while the high-torque screw 662 generates axial displacement. Since the high-torque nut 665 forms a circumferential limit with the annular rail 663 through the movable ring 664, according to the principle of screw transmission, the linear motion of the high-torque screw 662 is converted into the rotational motion of the high-torque nut 665. The high-torque nut 665 drives the outer connecting plate 6521, the inclined plate 6522 and the cleaning brush plate 6523 to rotate. The cleaning brush plate 6523, which is in close contact with the outer surface of the conical filter screen 632, removes dirt such as leaves and mud through friction, realizing automatic cleaning. The high-elasticity return spring 655 stores energy when compressed and releases elastic potential energy after the vehicle leaves, pushing the slip ring 656 and the connecting component 67 to reset, preparing for the next cleaning cycle. The filtered rainwater is discharged into the urban drainage system through the bottom of the main sleeve 61 and the main drainage pipe 9, completing the drainage process.

[0019] Please refer to Figures 5-10The drive mechanism 66 includes an inner frame 661 and a high-torque screw 662. The inner frame 661 is fixedly installed on the inner side of the base ring 654. An annular rail 663 is fixedly connected inside the inner frame 661. A movable ring 664 is slidably connected inside the annular rail 663. A high-torque nut 665 is fixedly connected to the inner side of the movable ring 664. The high-torque screw 662 is fixedly connected to the bottom of the connecting assembly 67. The high-torque nut 665 is threaded to the outer surface of the high-torque screw 662. The cleaning brush assembly 652 includes a connecting plate 6521. The connecting plates 6521 are arranged in a ring at equal intervals and fixedly connected to the high-torque screw. On the bottom outer side of the mother 665, a sloping plate 6522 is fixedly connected to the bottom of the connecting plate 6521. A cleaning brush plate 6523 is fixedly installed on the outer end of the sloping plate 6522. The inner side of the cleaning brush plate 6523 is in close contact with the outer surface of the filter screen 632. The connecting assembly 67 includes a cross 671, which is fixedly installed on the inner side of the slip ring 656. A cross seat 672 is fixedly connected to the top of the cross 671. A connecting post 673 is fixedly connected to the top of the cross seat 672. A high-torque screw 662 is fixedly connected to the middle of the bottom of the cross 671. The top of the connecting post 673 is connected to the intersection buffer strip. The bottom of section 5 is connected. During the application of this equipment, when a vehicle runs over the roadway buffer strip 5, the pressure is transmitted to the cross seat 672 and the cross 671 through the connecting column 673, causing the slip ring 656 to slide down inside the main sleeve 61. At the same time, the high-torque screw 662, which is fixed in the middle of the bottom of the cross 671, generates axial displacement. Since the high-torque nut 665 is slidably connected to the annular rail 663 inside the inner frame 661 through the movable ring 664, its vertical movement is limited but it can rotate circumferentially. According to the principle of screw transmission, the linear motion of the high-torque screw 662 is converted into the rotational motion of the high-torque nut 665. When 665 rotates, it drives the connecting plates 6521, which are arranged in a ring at equal intervals on the outer side of the bottom, to rotate. The connecting plates 6521 cause the cleaning brush 6523 to rotate synchronously through the inclined plate 6522. The cleaning brush 6523, which is in close contact with the outer surface of the conical filter screen 632, effectively removes the dirt attached to the screen by using the friction generated by the rotation. After the vehicle leaves, the high-elasticity return spring 655 releases its elastic potential energy, pushing the slip ring 656 and the connecting assembly 67 to reset. The high-torque screw 662 moves upward, and the high-torque nut 665 rotates in the opposite direction, so that the cleaning brush 6523 returns to its initial position, ready for the next cleaning.

[0020] Please refer to Figures 5-10The cleaning mechanism 65 includes an inner ring 651 and a cleaning brush assembly 652. The inner ring 651 is placed on top of the inner limiting ring 64. A support shaft 653 is fixedly installed on the top of the inner ring 651 in a ring-like arrangement at equal intervals. A base ring 654 is fixedly installed on the top of the support shaft 653. A high-elasticity return spring 655 is fixedly connected to the top of the base ring 654 in a ring-like arrangement at equal intervals. A slip ring 656 is fixedly installed on the top of the high-elasticity return spring 655. The slip ring 656 is slidably connected to the upper inner part of the main sleeve 61. A connecting assembly 67 is fixedly installed on the slip ring 656. Inside ring 656, drive mechanism 66 is fixedly installed inside base ring 654. Cleaning brush assembly 652 is fixedly connected to the bottom of drive mechanism 66. Filter screen 632 is generally conical in shape, with its top connected to the bottom of cleaning mechanism 65. During application, when a vehicle runs over the road buffer strip 5, pressure is transmitted to slip ring 656 through connecting assembly 67. Slip ring 656 slides downward inside the main sleeve 61, compressing the high-elasticity return spring 655. Slip ring 656 moves downward, causing it to be fixed to the base ring 654. The inner drive mechanism 66 descends synchronously, and the high-torque screw 662 in the drive mechanism 66 moves axially. Based on the principle of screw transmission, the high-torque nut 665, which is threadedly connected to the high-torque screw 662, rotates. The high-torque nut 665 drives the cleaning brush assembly 652 connected to its bottom to rotate. The cleaning brush plate 6523, which is in close contact with the outer surface of the conical filter screen 632, removes the dirt attached to the screen through rotational friction. After the vehicle drives away, the compressed high-elasticity return spring 655 releases its elastic potential energy and pushes upward. The moving slip ring 656 resets, and the slip ring 656 drives the inner ring 651, the base ring 654 and the drive mechanism 66 to move upward through the support shaft 653. The high-torque screw 662 rises accordingly, and the high-torque nut 665 rotates in the opposite direction to return the cleaning brush assembly 652 to its initial position. During this process, the inner ring 651 placed on top of the inner limit ring 64 plays a supporting and positioning role, ensuring that the cleaning mechanism 65 moves stably in the vertical direction, while ensuring that the cleaning brush assembly 652 and the filter screen 632 always remain in contact, so as to achieve a continuous and effective automatic cleaning function.

[0021] Please refer to Figures 1-7The intersection buffer strip 5 has an isosceles triangle shape on its sides and an arc-shaped top. Anti-slip grooves 7 are linearly arranged at equal intervals on both sides of the intersection buffer strip 5. The bottom of the anti-slip grooves 7 connects the intersection buffer strip 5 and the drainage trough 2. Water guide channels 8 are located on both sides of the drainage trough 2 at the top of the road surface 1. The water guide channels 8 are inclined downwards towards the drainage trough 2. The filter assembly 63 includes an inner mounting cylinder 631, which is fixedly installed at the bottom of the main sleeve 61. A filter screen 632 is fixedly installed inside the inner side of the inner mounting cylinder 631. During the application of this device, the water guide channels 8 on both sides of the drainage trough 2 at the top of the road surface 1 guide rainwater at a specific angle, using gravity to quickly and efficiently divert the accumulated water on the road surface 1 to the drainage trough 2 in the middle. The drainage troughs 3, evenly distributed within the drainage trough 2, are connected to the filter device 6. Rainwater flows through the drainage channels... Water trough 3 enters the main sleeve 61. The inner sleeve 631 at the bottom of the main sleeve 61 and the filter screen 632 on its inner side intercept and filter impurities such as leaves and mud carried in the rainwater, ensuring that the discharged water is relatively clean. The filtered rainwater is discharged into the urban drainage system through the main drainage pipe 9. The side of the intersection buffer strip 5 is designed as an isosceles triangle with a rounded transition at the top. When a vehicle passes over it, this structure can effectively reduce the vehicle speed and reduce the impact and vibration when the vehicle runs over it. At the same time, the rounded top can prevent water accumulation. The anti-slip grooves 7 on both sides of the buffer strip are arranged linearly, and their bottoms penetrate the buffer strip and are connected to the drainage trough 2. On the one hand, the anti-slip grooves 7 increase the roughness of the road surface 1, effectively improving the friction when the vehicle brakes and reducing the risk of slipping. On the other hand, they can promptly introduce the water accumulated on the buffer strip into the drainage trough 2, assisting the entire drainage system to drain water quickly and ensuring that the water accumulated on the road surface 1 is removed in a timely manner.

[0022] The implementation principle of a drainage system for municipal road construction according to an embodiment of this application is as follows: This system uses the traffic pressure of road users as the core power source. When a vehicle travels to the buffer strip 5 at the intersection, the vertical pressure on the buffer strip forms a stable force transmission path through the connecting component 67: the connecting column 673 transmits the pressure downward to the cross 671 and the cross seat 672, driving the slip ring 656 to move precisely downward along the inner wall of the main sleeve 61; at the same time, the high-torque screw 662 at the bottom of the cross 671 synchronously generates axial displacement. Since the high-torque nut 665 forms a circumferential limiting structure with the annular rail 663 through the movable ring 664, its vertical movement freedom is restricted. According to the mechanical principle of screw transmission, the linear motion of the high-torque screw 662 is efficiently converted into the rotational motion of the high-torque nut 665. During the motion conversion process, the high-torque nut 665 drives the outer fixed connecting plate 6521, inclined plate 6522 and cleaning brush 6523 to rotate synchronously. The inner side of the cleaning brush 6523 is in close contact with the outer surface of the conical filter screen 632. Through the friction generated by the rotation, various dirt such as leaves, mud, and plastic bags attached to the surface of the screen are effectively removed. During the cleaning operation, the high-elasticity return spring 655 is in a compressed and stored energy state. When the vehicle leaves and the pressure is released, the high-elasticity return spring 655 quickly releases its elastic potential energy, pushing the slip ring 656 and connecting component 67 to accurately reset, preparing for the next cleaning cycle. This power conversion mechanism completely abandons the electric drive mode, avoiding the risk of leakage, circuit aging and short circuit failure that are prone to occur in traditional electric cleaning devices in humid environments. It significantly improves the system's operational stability and equipment service life, and is particularly suitable for application scenarios where municipal roads are exposed to rainwater for a long time. This system constructs a complete treatment system including rainwater collection, filtration, and self-cleaning. The water guide channels 8 on both sides of the road surface 1 adopt a scientific tilt angle design. Based on the principle of fluid mechanics, it can quickly and efficiently divert rainwater from the road surface 1 to the central drainage channel 2. The anti-slip drainage channel 7 can also assist in the drainage function. At this time, the water is evenly distributed to each filter device 6 through the equally spaced drainage channels 3. The conical filter screen 632 in the filter component 63 breaks through the structural limitations of traditional flat filter screens. The conical surface setting can increase the effective filtration area and improve the interception ability of impurities in rainwater. At the same time, the slope characteristics of the conical structure allow the intercepted dirt to slide off naturally under the action of gravity, reducing the adhesion and accumulation of impurities. Combined with the periodic rotation cleaning of the cleaning brush 6523, a dual anti-clogging mechanism combining physical interception and dynamic cleaning is formed to ensure the long-term stable operation of the drainage system. The intersection buffer strip 5 retains the traditional deceleration function while innovating its structure. The anti-slip grooves 7 designed on the side are regularly distributed. On the one hand, by increasing the roughness of the road surface 1, it effectively improves the friction of the vehicle during braking and reduces the risk of slippage. On the other hand, the grooves are directly connected to the drainage channel 2, which can drain the water on the buffer strip in time and avoid the risk of vehicle loss of control due to water accumulation. The top of the buffer strip adopts an arc transition design, which not only reduces the impact and vibration when the vehicle runs over it and reduces the damage to the surrounding structure, but also prevents water residue. The high-elasticity return spring 655 installed inside has a dual function. It not only undertakes the return function of the cleaning mechanism 65, but also acts as a mechanical buffer element to absorb the impact force when the vehicle runs over it, protect the internal transmission structure, and extend the overall service life of the equipment. In terms of equipment maintenance, the system adopts a modular assembly design. The inner ring 651 and the inner limiting ring 64 are embedded to form a detachable connection structure. When maintenance is required, the operator only needs to pull the intersection buffer strip 5 and the matching main sleeve 61 out of the drainage tank 3 as a whole to separate the drainage system. Further disassembling the main sleeve 61 allows for the quick removal of the inner ring 651 and its top cleaning mechanism 65, drive mechanism 66 and connecting component 67, enabling unobstructed cleaning and replacement of the filter screen 632. This design simplifies the complex maintenance process of traditional drainage devices, greatly shortens maintenance time, and reduces the difficulty of manual operation and maintenance costs. In terms of engineering practicality, the system optimizes resource utilization through functional integration. Traditional municipal construction requires the separate installation of speed bumps and drainage devices. This system combines the two into one, reducing the space occupied on the road surface and lowering the overall cost of material procurement, installation, construction, and subsequent maintenance. The automated cleaning mechanism significantly improves the operational stability of the drainage system, effectively reduces the frequency of filter clogging, and extends the maintenance cycle. It is particularly suitable for municipal road projects with long construction cycles and frequent drainage needs, ensuring construction progress and road traffic efficiency. In terms of safety performance enhancement, the anti-slip design and efficient drainage function of the intersection buffer strip 5 work synergistically. The anti-slip groove 7 and the arc top design have been professionally tested and verified, which can effectively improve vehicle braking stability and reduce the risk of driving in rainy weather. The efficient drainage system can quickly drain the water accumulated on the road surface 1 under heavy rainfall conditions, avoiding safety hazards such as blurred vision and vehicle skidding and loss of control caused by water accumulation, and providing reliable safety protection for the construction area and surrounding roads. In terms of environmental protection and sustainable development, the system innovatively adopts a non-electric drive mode, reducing energy consumption and carbon emissions at the source, which is in line with the concept of green construction. The modular design enables each component to be replaced independently. Key components such as the filter screen 632 and the cleaning brush 6523 adopt standardized interfaces, which greatly improves replacement efficiency, reduces resource waste caused by the overall scrapping of equipment, and reduces the environmental impact of municipal engineering throughout its entire life cycle, which is in line with the current development trend of low-carbon operation and maintenance in urban construction.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
