Abstract
Description
Technical Field
[0001] This invention relates to the field of municipal engineering technology, specifically to a rapid drainage device and method for municipal roads. Background Technology
[0002] With the acceleration of urbanization, the area of paved municipal roads continues to expand, and the amount of rainwater infiltration has decreased significantly. Extreme rainfall can easily cause road flooding. Traditional rainwater drainage systems mostly rely on fixed pipe networks, which have problems such as long water collection paths and slow drainage flow rates. Moreover, the pipe networks are easily blocked by debris such as mud and fallen leaves, further reducing drainage efficiency. Road flooding can not only cause traffic paralysis, but also damage road structures, soak surrounding facilities, and threaten the safety of pedestrians and vehicles. Existing drainage devices are mostly single diversion structures, lacking an integrated design for rapid water collection, anti-blockage and silt removal, making it difficult to meet the emergency drainage needs under short-term heavy rainfall.
[0003] As urban transportation hubs, municipal roads require extremely high stability and timeliness in their drainage systems. Currently, most cities employ gravity-flow drainage, which is significantly limited by terrain and pipe network slopes, leading to water accumulation in low-lying areas and intersections. Furthermore, traditional drainage devices suffer from poorly designed filter structures, frequently resulting in blockages due to debris accumulation, and are difficult and costly to maintain and clean. In addition, existing drainage methods largely rely on manual initiation or passive drainage, lacking proactive response mechanisms and failing to quickly adapt to changes in rainfall intensity. With the increasing frequency of extreme rainfall events, traditional drainage technologies are struggling to cope with the growing risk of urban flooding. There is an urgent need for a device and supporting methods that integrate rapid water collection, blockage prevention, and efficient drainage to enhance the emergency drainage capacity of municipal roads. Summary of the Invention
[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a rapid drainage device and method for municipal roads, so as to solve the problems that the drainage devices in the prior art are prone to clogging, difficult to clean, overly dependent on manual labor, lack an active response mechanism, and cannot automatically adapt to changes in rainfall intensity.

[0010] Furthermore, the water tank is equipped with a high-pressure nozzle, which sprays high-pressure water at the outlet of the waste storage box.
[0011] In an embodiment of the present invention, a rotating blade is movably installed on the inner top of the processing box corresponding to the position of the buffer box, and a brush is fixedly installed on the side of the rotating blade near the buffer box; the rotating blade is a corrosion-resistant oblique rotating blade, and the brush is a corrosion-resistant soft brush.

[0013] In an embodiment of the present invention, a connecting block for fixed connection with an external structure is fixedly installed on the outside of the water storage tank.
[0014] This invention also provides a method for rapid drainage of rainwater from municipal roads. This method uses the aforementioned rapid drainage device for municipal roads and specifically includes the following steps:
[0015] S1. Installation preparation: Install the device at a low-lying, flood-prone spot on the road or at a rainwater collection point, ensuring that the water inlet trough on the top of the buffer box is flush with or slightly lower than the road surface; connect the first interface to the municipal rainwater pipe network and the second interface to the sewage pipe network or connect to the garbage collection equipment; turn on the power and start the control system, so that the rain sensor, water level sensor, flow sensor, and pressure sensor enter the standby monitoring state.
[0016] S2, Rainwater Buffering and Collection: During rainfall, the rain gauge monitors the rainfall intensity in real time, and the rainwater enters the buffer tank through the inlet trough for slow flow. The flow sensor monitors the inlet flow rate in real time.
[0017] S3. Pre-treatment of large debris separation: The buffered rainwater flows into the treatment tank and flows along the guide plate. The debris in the water is guided by the guide plate to the garbage storage box. At the same time, the water flow impacts the rotating blades, which drive the brush to rotate synchronously, breaking up the tangled debris and cleaning the tank wall.
[0018] S4. Waste compression and dehydration: When the debris in the waste storage box accumulates to the preset amount, the control system drives the telescopic column to drive the pressure plate to compress the waste, and the squeezed water flows back to the processing box through the filter plate.
[0019] S5. Water Filtration: After separating large debris, rainwater enters the filter box through the water pipe, where it passes through the filter plate to trap mud, sand, and small particulate impurities, thus completing solid-liquid separation.
[0020] S6. Clean water storage monitoring: Filtered clean water flows into a water storage tank for temporary storage, and a water level sensor monitors the water level in the water storage tank in real time.
[0021] S7, Intelligent Drainage and Flood Control:
[0022] Normal mode: When the water level reaches the preset high water level, the control system starts the drainage pump to discharge the rainwater in the water storage tank into the municipal rainwater pipe network through the first interface;
[0023] Forced drainage mode: When the rain sensor detects that the rainfall intensity exceeds the threshold, or the flow sensor detects that the inflow rate exceeds the preset value, the control system starts in advance or increases the power of the drainage pump to carry out forceful drainage.
[0024] Alarm mode: When the pressure sensor detects that the municipal pipe network pressure is too high or the drainage is blocked, the control system triggers an alarm and activates the emergency plan;
[0025] S8. Waste transfer and disposal:
[0026] When the garbage storage box is full or a single drainage cycle is completed, the telescopic plate retracts and opens the outlet to transfer the compressed garbage into the garbage bin, and then the telescopic plate resets; the shredder inside the garbage bin shreds and reduces the volume of the garbage; sanitation workers regularly remove the shredded garbage residue through the second interface;
[0027] S9. Maintenance and Reset: After the flood drainage is completed, the control system stops the drainage pump; regularly clean the sediment on the filter plate, check the working status of each component, and restore the device to standby state.
[0028] As can be seen from the above embodiments, the municipal road rainwater rapid drainage device provided by the present invention has at least the following benefits: This rapid drainage device effectively solves the problem of easy clogging in traditional drainage devices through multi-stage filtration and intelligent processing. After rainwater is slowed down by the buffer tank, large debris is guided by the guide plate to the garbage temporary storage box. The rotating blades and brushes break up the tangled debris, and the telescopic column pushes the pressure plate to compress and dehydrate the garbage, reducing its volume while avoiding secondary clogging. The shredder further processes the garbage residue, greatly improving storage and transportation efficiency. This integrated design realizes full-process automation of debris separation, compression, and shredding, significantly reducing maintenance frequency and ensuring continuous unobstructed drainage channels.
[0029] Furthermore, this municipal road stormwater rapid drainage device significantly improves emergency drainage response speed and adaptability through a multi-sensor collaborative intelligent drainage control strategy. Rainfall, water level, flow rate, and pressure sensors monitor environmental data in real time, intelligently switching between conventional and forced drainage modes based on rainfall intensity, and triggering alarms when pipe network pressure is too high. This drainage device combines a buffer tank for flow stabilization with a high-efficiency filtration structure, greatly accelerating rainwater throughput efficiency. This dynamic control mechanism effectively overcomes the limitations of traditional gravity drainage due to terrain constraints, achieving a leap from passive drainage to active intervention, providing rapid and adaptive drainage protection for low-lying urban road sections and intersections.

Detailed Implementation
[0040] Various exemplary embodiments of the present invention will now be described in detail. This detailed description should not be considered as a limitation of the present invention, but rather as a more detailed description of certain aspects, features, and embodiments of the present invention.
[0041] Various modifications and variations can be made to the specific embodiments described in this specification without departing from the scope or spirit of the invention, as will be apparent to those skilled in the art. Other embodiments derived from this specification will also be obvious to those skilled in the art. This application specification and embodiments are merely exemplary.
[0042] This invention provides a rapid rainwater drainage device for municipal roads, such as... Figure 1-5As shown, the drainage device includes a housing 1, a connecting box 2 fixedly installed on one side of the housing 1, and a drainage mechanism 3 fixedly installed inside the housing 1. The drainage mechanism 3 includes a buffer tank 315, a treatment tank 306, a filter tank 304, and a water storage tank 301 arranged sequentially from top to bottom. The buffer tank 315 is fixedly installed on top of the treatment tank 306 and communicates with the treatment tank 306. The top of the buffer tank 315 has a water inlet trough, and a flow sensor 316 is fixedly installed inside it for real-time detection of rainwater flow and uploading to the control system.
[0043] A guide plate 307 is fixedly installed inside the processing bin 306. The guide plate 307 is inclined and has a smooth surface. Its bottom end corresponds to the opening above the waste storage box 308, which is used to guide waste into the waste storage box 308. At the same time, water also flows into the waste storage box 308. In this embodiment, the smooth inclined guide plate is made of a wear-resistant and corrosion-resistant smooth material, and its inclination angle is precisely matched with the material conveying path inside the processing bin. On the one hand, the smooth surface can significantly reduce the adhesion resistance of waste residue, avoiding waste from sticking and accumulating on the guide plate surface and forming blockages; on the other hand, the inclined structure can use gravity to guide the waste, which has been dispersed by the rotating blades and cleaned by the brush, to slide smoothly towards the waste bin, improving the efficiency of waste transfer. At the same time, it can also help to guide some water flow and avoid local water accumulation. Through the material and structural design of the smooth inclined guide plate, the problem of waste residue accumulation in the processing bin is solved, the transfer rhythm of waste to the subsequent collection stage is accelerated, the smooth flow of materials inside the processing bin is ensured, and the maintenance workload of manually cleaning the guide plate is reduced.
[0044] In addition, a filter plate 311 is fixedly installed at the bottom of the waste storage box 308 and is connected to the lower part of the treatment box 306, which is used to guide the water in the waste and the water that enters the upper part of the treatment box 306 through the buffer box 315 into the lower part of the treatment box 306.
[0045] The filter box 304 is fixedly installed at the bottom of the treatment box 306. A filter plate 305 is fixedly installed at the bottom of the filter box 304. A water guide pipe communicating with the filter box 304 is provided at the bottom of the treatment box 306 to guide the water in the treatment box 306 into the filter box 304 through the water guide pipe.
[0046] A water storage tank 301 is fixedly installed at the bottom of a filter box 304 and is interconnected with it via a filter plate 305. Water in the filter box 304 flows into the water storage tank 301 through the filter plate 305. Additionally, the water storage tank 301 is connected to a water tank 318 in a connecting box 2 via a water pump pipeline, allowing accumulated rainwater to be pumped into the water tank 318. In this embodiment of the invention, a water level sensor 302 is fixedly installed inside the water storage tank 301 for real-time monitoring of the water level inside the water storage tank 301.
[0047] A trash can 320 is fixedly installed inside the connecting box 2. The trash can 320 corresponds to the outlet position of the trash storage box 308 and is used to store and discharge trash.
[0048] A rain sensor 4 for monitoring rainfall is fixedly installed on the top of the outer casing 1, and a pressure sensor 319 for monitoring pipeline pressure is installed inside the connection box 2.
[0049] In a specific embodiment of the present invention, a telescopic column 309 is movably installed on the inner side of the waste storage box 308, that is, the telescopic column 309 is installed on the side near the middle of the processing box 306, and the extension direction is towards the side wall of the processing box 306. A pressure plate 310 is fixedly installed on the outer end of the telescopic column 309, and the telescopic column 309 can drive the pressure plate 310 to extend towards the side wall of the processing box 306.
[0050] In addition, a telescopic plate 312 extending vertically is movably installed on the side of the waste storage box 308 away from the pressure plate 310. When the telescopic plate 312 is opened, it connects the waste storage box 308 and the waste bin 320, and is used to push the waste into the waste bin 320 using the telescopic column 309 and the pressure plate 310, waiting for further processing.
[0051] Furthermore, a second interface 6 is fixedly installed at the bottom of the trash can 320. The second interface 6 extends to the outside of the connecting box 2 and is used to export the trash inside the trash can 320 to the outside of the connecting box 2.
[0052] Furthermore, a shredder 321 is fixedly installed inside the trash can 320 to shred the trash inside the trash can 320, making it easier to export and transfer the trash.
[0053] In a specific embodiment of the present invention, the water tank 318 inside the connecting box 2 is located on top of the garbage bin 320. A pressure sensor 319 is fixedly installed on the inner top of the water tank 318 to detect the pipeline pressure and upload the pressure value to the control system.
[0054] In addition, a first interface 5 is fixedly installed on the top of the connecting box 2. The first interface 5 is connected to the connection port of the municipal rainwater pipe network. An interface cover is movably installed on the top of the first interface 5 to protect the interface. In this embodiment, the interface cover adopts a hinge + buckle movable installation structure, which can be tightly closed when not in drainage conditions, thus preventing external dust, fallen leaves and other debris from entering the interior of the first interface 5 and avoiding blockage of the interface channel. At the same time, it can seal the connection gap between the interface and the municipal pipe network, reducing the diffusion of odors from the pipe network. During drainage operations, the interface cover can be automatically opened with the water flow pressure, and can also be remotely controlled to open via the control module, without hindering the discharge and flow of rainwater into the municipal pipe network. In this embodiment, the interface cover is hinged and rotated inside the pipe of the first interface, and it can be flipped open along the water flow direction.
[0055] Furthermore, the water tank 318 is equipped with a high-pressure nozzle, which can spray high-pressure water at the outlet of the waste storage box 308. The water in the water tank 318 is used to spray and clean the waste, and help flush the waste into the waste bin 320.
[0056] In a specific embodiment of the present invention, a rotating blade 313 is movably installed on the inner top of the processing box 306 corresponding to the position of the buffer box 315, and a brush 314 is fixedly installed on the side of the rotating blade 313 near the buffer box 315.
[0057] The rotating blade 313 is a corrosion-resistant, angled blade, and the brush 314 is a corrosion-resistant soft brush. The angled blade is made of corrosion-resistant engineering plastic or stainless steel, which helps resist the erosion of mud and pollutants carried by rainwater, preventing rust and damage after long-term use and extending the blade's lifespan. Furthermore, the angled blade shape efficiently breaks up large pieces of waste entering the treatment tank during rotation, preventing waste accumulation and clogging of subsequent pipes, and also helps guide water flow to the water pipes at the bottom of the treatment tank, improving rainwater transport efficiency. Through the material and structural design of the corrosion-resistant angled blade, the durability of the blade itself is enhanced, reducing the frequency of maintenance and replacement; the effect of waste breaking up and water flow guidance within the treatment tank is strengthened, further improving the device's anti-clogging capability and the smoothness of rainwater treatment.
[0058] This corrosion-resistant soft brush is made of a flexible, acid- and alkali-resistant material. On one hand, it resists the erosion of various corrosive pollutants carried by rainwater, and is not prone to aging or damage over long-term use. On the other hand, the soft bristles, when brushing with the rotating blades, can closely conform to the inner wall of the treatment tank and the surface of the rotating blades, efficiently cleaning attached garbage residue and silt, without scratching or abrading internal components, ensuring the integrity of the parts. Through the material and shape design of the corrosion-resistant soft brush, the service life of the brush is extended, reducing the maintenance cost of component replacement; it also achieves efficient cleaning of the internal parts of the device, reducing the risk of garbage residue clogging, and avoiding damage to other components during the cleaning process, making the garbage treatment process in the treatment tank more stable and reliable.
[0059] In a specific embodiment of the present invention, a connecting block 303 for fixed connection with an external structure is fixedly installed on the outside of the water storage tank 301.
[0060] In addition, a conduit 317 is fixedly installed on the side of the buffer box 315.
[0061] The top of the buffer tank 315 is equipped with a water inlet trough for easy water delivery. The inlet trough features a wide-mouth, gently sloping design, which expands the coverage area for water accumulation in low-lying areas and accelerates the initial water collection speed. Simultaneously, the gentle slope within the trough weakens the impact of incoming rainwater, preventing direct impact on the internal components of the buffer tank and avoiding damage. It also provides stable flow conditions for the subsequent initial separation of rainwater and waste. Through the wide-mouth collection and gentle flow guidance of the inlet trough, the buffer tank can more efficiently collect road surface water, while ensuring a smoother and more orderly processing flow after the rainwater enters the device, including waste separation and rainwater filtration, reducing component failures or decreased processing efficiency caused by water flow impact.
[0062] This invention provides a method for rapid drainage of rainwater from municipal roads. This drainage method utilizes the aforementioned rapid rainwater drainage device for municipal roads, and the specific steps include:
[0063] Step S1, Installation Preparation: Install the device at a low-lying, flood-prone spot on the road or at a rainwater collection point, ensuring that the top water inlet of the buffer box 315 is flush with or slightly lower than the road surface; connect the first interface 5 to the municipal rainwater pipe network and the second interface 6 to the sewage pipe network or connect to the garbage collection equipment; turn on the power and start the control system, so that the rainfall sensor 4, water level sensor 302, flow sensor 316, and pressure sensor 319 enter the standby monitoring state.
[0064] Step S2, Rainwater Buffering and Collection: During rainfall, the rain sensor 4 monitors the rainfall intensity in real time, and the rainwater enters the buffer tank 315 through the inlet trough for slow flow. The flow sensor 316 monitors the inlet flow rate in real time.
[0065] Step S3, pre-treatment of large debris separation: The buffered rainwater flows into the treatment tank 306 and flows along the guide plate 307. The debris in the water is guided by the guide plate 307 to the garbage storage box 308. At the same time, the water flow impacts the rotating blade 313 to rotate, which drives the brush 314 to rotate synchronously, breaking up the tangled debris and cleaning the guide plate 307 and the tank wall to prevent blockage.
[0066] Step S4, Waste Compression and Dehydration: When the debris in the waste storage box 308 accumulates to a preset amount, the control system drives the telescopic column 309 to move the pressure plate 310 to compress the waste. The squeezed-out water flows back to the processing box 306 through the filter plate 311. This process can be run intermittently automatically or according to the pressure signal.
[0067] Step S5, Water Filtration: After separating large debris, the rainwater enters the filter box 304 through the water pipe, and the filter plate 305 intercepts mud, sand and small particulate impurities, completing the solid-liquid separation.
[0068] Step S6, Clean water storage monitoring: The filtered clean water flows into the water storage tank 301 for temporary storage, and the water level sensor 302 monitors the water level in the water storage tank 301 in real time.
[0069] Step S7, Intelligent Drainage and Flood Control:
[0070] Normal mode: When the water level reaches the preset high water level, the control system starts the drainage pump to discharge the rainwater in the water storage tank 301 into the municipal rainwater pipe network through the first interface 5, so as to achieve rapid flood drainage.
[0071] Forced drainage mode: When the rain sensor 4 detects that the rainfall intensity exceeds the threshold, or the flow sensor 316 detects that the inflow rate exceeds the preset value, the control system starts or increases the power of the drainage pump in advance to carry out preventive forceful drainage.
[0072] Alarm mode: When the pressure sensor 319 detects that the municipal pipe network pressure is too high or the drainage is blocked, the control system triggers an alarm and starts the emergency plan.
[0073] Pressure sensor 319 connects to the municipal rainwater pipe network at the first interface 5 via a pressure tapping pipeline to collect water pressure in the pipe network in real time. When the pressure is abnormal, it transmits an abnormal signal to the control system.
[0074] Step S8, Waste Transfer and Processing:
[0075] When the temporary waste storage box 308 is full or a single drainage cycle is completed, the telescopic plate 312 retracts and opens the outlet, transferring the compressed waste into the waste bin 320. The telescopic plate 312 then resets, ready for the next collection. The shredder 321 inside the waste bin 320 shreds and reduces the volume of the waste, greatly facilitating storage and subsequent transportation. Sanitation workers regularly remove the shredded waste residue through the second interface 6.
[0076] Step S9, Maintenance and Reset: After the drainage is completed, the control system stops the drainage pump. Regularly clean the sediment on the filter plate 305, check the working status of each component, and restore the device to standby mode.
[0077] Among them, step S1, interface docking and sensor standby, is the basis for operation; step S2, buffer tank flow stabilization and flow sensor data supply; step S3, rotating blade brush linkage anti-clogging; step S4, garbage compression and volume reduction and filtered water return; step S5, filter plate to block silt; step S6, water level monitoring to trigger drainage; step S7, multi-mode adaptation to rainfall intensity; step S8, automated garbage collection; and step S9, regular maintenance to ensure device stability.
[0078] Through this set of steps, the rapid drainage device achieves a closed loop for rainwater treatment, solves the problem of easy blockage in traditional drainage systems, adapts to different rainfall scenarios, and achieves the goals of rapid drainage and efficient garbage removal.
[0079] In summary, this municipal road rapid rainwater drainage device effectively solves the problem of easy clogging in traditional drainage devices through multi-stage filtration and an intelligent waste treatment system. After rainwater is slowed down by the buffer tank 315, large debris is guided by the guide plate 307 to the waste storage box 308. The rotating blades 313 and brushes 314 rotate and break up tangled debris. The telescopic column 309 pushes the pressure plate 310 to compress and dehydrate the waste, reducing its volume and preventing secondary clogging. The shredder 321 further processes the waste residue, greatly improving storage and transportation efficiency. This integrated design realizes full automation of the process of debris separation, compression, and shredding, significantly reducing maintenance frequency and ensuring continuous unobstructed drainage channels. It is especially suitable for complex road conditions with a mixture of leaves and mud.
[0080] Furthermore, through a multi-sensor collaborative intelligent drainage control strategy, the emergency drainage response speed and adaptability are significantly improved. Rainfall, water level, flow rate and pressure sensors 319 monitor environmental data in real time. The system can intelligently switch between conventional drainage and forced drainage modes based on rainfall intensity and trigger an alarm when the pipeline pressure is too high. Combined with the flow stabilization and high-efficiency filtration structure of the buffer tank 315, the rainwater throughput efficiency is greatly accelerated. This dynamic control mechanism effectively overcomes the shortcomings of traditional gravity drainage which is constrained by terrain, and realizes a leap from passive drainage to active intervention, providing rapid and adaptive drainage protection for low-lying urban road sections and intersections.
[0081] The above description is merely an illustrative embodiment of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention.

10. A method for rapid drainage of rainwater from municipal roads, characterized in that, The method of using the municipal road stormwater rapid drainage device according to any one of claims 1-9 includes: S1. Installation preparation: Install the device at a low-lying, flood-prone spot on the road or at a rainwater collection point, so that the top water inlet of the buffer box (315) is flush with or slightly lower than the road surface; connect the first interface (5) to the municipal rainwater pipe network and the second interface (6) to the sewage pipe network or connect to the garbage collection equipment; turn on the power and start the control system, so that the rain sensor (4), water level sensor (302), flow sensor (316), and pressure sensor (319) enter the standby monitoring state; S2, Rainwater buffer collection: During rainfall, the rain sensor (4) monitors the rainfall intensity in real time, and the rainwater enters the buffer tank (315) through the inlet trough for slow flow. The flow sensor (316) monitors the inlet flow rate in real time. S3, pretreatment of large debris separation: after buffering, the rainwater flows into the treatment tank (306) and flows along the guide plate (307). The debris in the water is guided by the guide plate (307) to the garbage storage box (308). At the same time, the water flow impacts the rotating blade (313) to rotate, which drives the brush (314) to rotate synchronously, breaking up the tangled debris and cleaning the tank wall. S4. Waste compression and dehydration: When the debris in the waste storage box (308) accumulates to the preset amount, the control system drives the telescopic column (309) to drive the pressure plate (310) to compress the waste, and the squeezed water flows back to the processing box (306) through the filter plate (311). S5. Filtration and purification: After the rainwater is separated from large debris, it enters the filter box (304) through the water pipe and is filtered by the filter plate (305) to trap mud, sand and small particulate impurities, thus completing the solid-liquid separation. S6. Clean water storage monitoring: Filtered clean water flows into the water storage tank (301) for temporary storage, and the water level sensor (302) monitors the water level in the water storage tank (301) in real time; S7, Intelligent Drainage and Flood Control: Normal mode: When the water level reaches the preset high water level, the control system starts the drainage pump to discharge the rainwater in the water storage tank (301) into the municipal rainwater pipe network through the first interface (5); Forced drainage mode: When the rain sensor (4) detects that the rainfall intensity exceeds the threshold, or the flow sensor (316) detects that the inflow rate exceeds the preset value, the control system starts or increases the power of the drainage pump in advance to carry out forceful drainage. Alarm mode: When the pressure sensor (319) detects that the municipal pipeline pressure is too high or the drainage is blocked, the control system triggers an alarm and starts the emergency plan; S8. Waste transfer and disposal: When the garbage storage box (308) is full or the single-cycle drainage cycle is over, the telescopic plate (312) retracts and opens the outlet, transferring the compressed garbage into the garbage bin (320), and the telescopic plate (312) resets; the shredder (321) in the garbage bin (320) shreds and reduces the volume of the garbage; sanitation workers regularly remove the shredded garbage residue through the second interface (6); S9. Maintenance and Reset: After the drainage is completed, the control system stops the drainage pump; regularly clean the sediment on the filter plate (305), check the working status of each component, and restore the device to standby state.
