Description

Technical Field

[0001] The invention relates to the technical field of municipal drainage, and in particular to a suspended frame pipe-type drainage culvert sedimentation prevention device and method. Background Art

[0002] As of the beginning of 2024, the total length of urban drainage pipes and culverts in China has reached 913,500 kilometers. As the core infrastructure of the urban water environment security system, urban drainage pipes and culverts are an important part of the urban lifeline system. They play an important role in ensuring the orderly collection, transportation and treatment of urban sewage and maintaining the daily operation of the city, and they play a vital role in reducing and preventing urban water disasters.

[0003] However, with the continuous advancement of my country's urbanization process, the burden of collecting, transporting and discharging various types of sewage / wastewater borne by urban drainage networks has become increasingly heavy, and the problem of sediment deposition in drainage culverts has become increasingly prominent, arousing widespread social concern.

[0004] Sediments in drainage culverts will reduce the water-passing cross-section of the culvert, increase the pressure at the peak of drainage, and enhance the water flow resistance, which can easily cause poor drainage, overflow or waterlogging of sewage / wastewater. If the sediments in the combined culvert or the separate stormwater culvert are not removed in time, they will be discharged into the surrounding rivers along with the rainwater during rainfall, causing the surface water to become black and smelly. In addition, the microorganisms in the sediments can use the organic matter in the sewage and the bottom sediment as metabolic substrates, decompose under anaerobic conditions, and release toxic and harmful gases such as hydrogen sulfide, methane and ammonia, causing corrosion of the pipe network, seriously endangering the health of the drainage pipe network maintenance personnel, and greatly reducing the service life of the pipe network.

[0005] There are two main sources of sediment in drainage culverts. One is the surface solid particles accumulated in the urban catchment area during the dry season, which are washed to the rainwater outlet and flow into the combined culvert or the separate stormwater culvert during rainy days; the other is the suspended solid particles contained in the collected sewage, which are deposited in the combined culvert or the separate sewage culvert. The former mainly deposits large inorganic particles, while the latter mainly contains organic pollutants, and its main source is domestic sewage. In addition, given that major cities in my country are actively promoting garbage sorting, a large amount of crushed kitchen waste will enter the drainage network from the kitchen sewers in residential areas, which will undoubtedly further increase the risk of sedimentation and blockage in drainage culverts.

[0006] In order to avoid the risk of culvert blockage, experts and scholars in related fields at home and abroad have developed a variety of culvert dredging methods in long-term engineering practice. Among them, the dredging methods suitable for urban drainage culverts mainly include winch dredging, high-pressure water jet dredging, ditch cleaning machine dredging, water flushing dredging, interception and flushing gates and dredging balls, etc. However, the above methods are basically designed for the dredging of small-diameter drainage culverts. Even if they are used for dredging of large-diameter drainage culverts, there are still problems such as high cost, insufficient capacity, secondary pollution and inability to adapt to complex terrain conditions.

[0007] At present, the design standard of drainage culverts in my country still adopts the minimum flow rate method. The current national standard "Outdoor Drainage Specification" (GB50014) stipulates that the minimum design flow rate of sewage culverts is 0.6m / s at the design fullness, which is still a certain gap compared with the design standard of the minimum flow rate of 0.8m / s to 1.0m / s in developed countries abroad, so the problem of culvert sedimentation is more prominent. Therefore, if the flow rate of the drainage culvert can be appropriately increased, the problem of culvert sedimentation can be fundamentally avoided. Therefore, the municipal drainage field urgently needs a new technology that can achieve long-term anti-sedimentation of drainage culverts through simple and efficient transformation. Summary of the invention

[0008] In view of the deficiencies in the prior art, the present invention provides a suspension frame pipe type drainage culvert anti-sedimentation device and method, which solves the problem of ensuring the normal water flow capacity of the drainage culvert by improving the flow velocity of water in the drainage culvert through the ingenious design of the suspension frame pipe, and effectively preventing the possibility of mud and sand deposition when the water flow rate is small; and during the implementation process, multiple suspension frame pipes of the same type are suspended and spliced ​​in the drainage culvert through the bearing groove on the suspension frame pipe, so as to achieve rapid construction and immediate operation; at the same time, an overflow plate is set on the water-facing surface of the first suspension frame pipe at the upstream of the drainage culvert between two adjacent inspection wells, so as to achieve the design function that water enters the suspension frame pipe first, and when the water flow is large, it overflows the overflow plate and overflows to the suspension frame pipe.

The socket is used to support the pipe of the suspension frame and collect overflow;

[0012] The support rod or wheel frame and the rotating wheel support the suspension frame pipe and the bearing groove;

[0013] The overflow plate is located on the water-facing surface of the most upstream trough and is used to overflow the excess water from the suspension frame pipe to the trough when the water flow is large;

[0014] The sensor network is arranged inside the suspension frame pipe and the trough. The sensors include flow rate sensor, sediment deposition sensor and liquid level sensor, which are connected to the central control system through the wireless Internet of Things module;

[0020] Preferably, the automatic silt removal device works in coordination with a hydraulic flushing system via a mechanical arm, the mechanical arm is used to clear large pieces of silt, and the hydraulic flushing system fully covers and flushes the pipeline with high-pressure water flow to ensure that the silt is completely removed.

[0021] Preferably, the energy recovery device collects kinetic energy of water through a micro-turbine or a piezoelectric device, can automatically adjust the recovery efficiency according to the intensity of the water flow, and provide stable electricity to supply the sensor network, central control system and automatic dredging device.

[0022] Preferably, the support rod may be a wheel frame and a rotating wheel structure, and the wheel frame and the rotating wheel can be automatically moved and adjusted through a central control system; the overflow plate is controlled by the central control system, and when the water flow exceeds the set flow rate, the overflow plate automatically adjusts the angle to ensure that the water flows smoothly into the trough without overflow blockage.

[0023] Preferably, the body of the socket is a circular, arc-shaped or semicircular structure, and the plug and the socket are designed to be waterproof and sealed to ensure leakage-proof performance between the sockets and when connected to the drainage culvert.

[0026] The present invention provides a suspension frame pipe type drainage culvert sedimentation prevention device and method.

[0027] Beneficial effects:

[0028] 1. The present invention sets a suspension frame pipe. When the water flow in the drainage culvert is small, the water will flow through the suspension frame pipe first. Since the cross-sectional area of ​​the frame pipe is small, the water flow area is effectively reduced, resulting in an increase in the flow rate, thereby preventing the sediment in the water flow from being deposited at the bottom of the pipe. At the same time, through the overflow plate control, when the flow is large, the water body can overflow into the trough through the top of the overflow plate, ensuring that it will not affect the existing flow capacity of the drainage culvert, thereby effectively avoiding the problems of sediment deposition and water congestion.

[0029] 2. The present invention can adapt to various types of drainage culverts, including gravity flow and pressure flow systems, and is suitable for pipes of different materials and diameters (such as PVC, HDPE, glass fiber reinforced plastic, etc.). Its modular design gives it good engineering adaptability and can be used in various complex environments. At the same time, the modular structure of the device enables it to be quickly installed in the daily maintenance or new construction of drainage culverts. The construction can be completed by simply pushing the suspension frame pipe and the socket into the drainage pipe one by one through the inspection well and docking them. No additional construction process is required, and the operation is simple.

[0030] 3. The present invention introduces a sensor network and a central control system to achieve real-time monitoring of water flow velocity, sediment deposition and water level changes. The automatic control of the sensor combined with the remote control of the central control system enables the system to automatically adjust the baffle and dredging device according to actual conditions to ensure that the system always maintains the best operating state. At the same time, when the sensor network detects that the sediment deposition exceeds the preset threshold, the automatic dredging device is activated, and the dredging is carried out using a mechanical arm and a hydraulic flushing system to ensure that the sediment will not accumulate for a long time, reduce the frequency of manual maintenance, and improve the dredging efficiency.

[0031] 4. The present invention uses an energy recovery device to effectively utilize the kinetic energy of water in the drainage culvert. The kinetic energy of water is converted into electrical energy through a turbine or piezoelectric device, which is used to power the sensor network, central control system and automatic silt removal device, thus achieving energy self-sufficiency of the device, further reducing the external energy consumption of the system, and improving the environmental benefits of the system.

[0032] 5. The present invention adopts the linkage design of the suspension frame pipe and the overflow plate. When the flow rate is small, the water flows into the frame pipe first, thereby increasing the flow rate and preventing sediment deposition. When the flow rate is large, the excess water overflows into the trough through the overflow plate, avoiding overflow or blockage of the pipeline due to excessive flow, ensuring the long-term stable operation of the system.

[0033] 6. The modular design and simple installation process of the present invention do not require additional power support or chemical maintenance. Combined with the automated control system, the present invention significantly reduces the need for manual maintenance and reduces operating costs. At the same time, the system ensures that the pipeline is always unobstructed through intelligent monitoring and automatic silt removal devices, greatly extending the service life of the drainage system, and has extremely high cost performance and comprehensive benefits as a whole.

[0034] 7. The present invention has good scalability and can adjust and upgrade the system according to the specific drainage pipe conditions and requirements. The sensor network and central control system can be linked with more types of environmental data, such as water quality testing, automated management of sewage treatment, etc., to further enhance the intelligence and green development level of the drainage system, which is in line with the development trend of future urban intelligent management.

DETAILED DESCRIPTION

[0039] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] See attached Figures 1 to 9 , 37-39, the present invention discloses a suspended frame pipe type drainage culvert sedimentation prevention device, which is arranged in a 1500×2000 drainage culvert and has the following structure:

[0041] The suspension frame pipe 1 is arranged along the axis of the drainage culvert 0 to guide the water flow and reduce the sediment deposition. The suspension frame pipe 1 is made of high-strength corrosion-resistant material (such as hard polyvinyl chloride UPVC), and its cross-section is egg-shaped, which can effectively reduce the water flow resistance and increase the water flow rate. The design of the suspension frame pipe 1 ensures its long-term operation in a variety of sewage environments and adapts to complex working conditions with different water qualities. The modular design produced by prefabricated molds makes the frame pipe have consistent size and easy installation.

[0042] The trough 2 is located below the suspension frame pipe 1, and is mainly used to support the suspension frame pipe 1 and collect excess water. The trough 2 includes a plurality of trough bodies 22, which are modularly docked through sockets 23 and sockets 24. The sockets 23 of each trough are waterproof and sealed to ensure that water does not leak between modules. The material of the trough 2 is UPVC, which can withstand long-term corrosive environments. The trough 2 also carries the suspension frame pipe 1, and fits tightly with the bottom of the drainage culvert 0 through the bottom, making the device more stable as a whole.

[0043] The support rod 21 is used to support the structural stability of the suspension frame pipe 1 and the trough 2. One end of the support rod 21 is connected to the bottom surface of the suspension frame pipe 1, and the other end is connected to the trough body 22 of the trough 2. The support rod adopts a modular and adjustable design to adapt to drainage pipes with different pipe diameters and terrain changes.

[0044] The overflow plate 3 is installed on the water-facing surface of the most upstream trough 2. Its function is to overflow the excess water from the suspension frame pipe 1 into the trough 2 when the water flow is large. The central opening design of the overflow plate 3 ensures that the cross-sectional size is consistent with the suspension frame pipe 1. When the water flow exceeds the set value, the water flow can smoothly pass through the overflow plate without affecting the normal drainage function of the system. At the same time, the overflow plate 3 can adjust the opening and closing angle through the command of the central control system 5, and adjust the overflow amount according to the actual water flow, further improving the efficiency of the drainage culvert.

[0045] The sensor network 4 is arranged at key positions inside the suspension frame pipe 1 and the trough 2, mainly including flow rate sensors, sediment deposition sensors and liquid level sensors. These sensors can monitor the water flow velocity, sediment deposition and water level changes inside the drainage culvert 0 in real time, and transmit the data to the central control system 5 through the Internet of Things module. The precise monitoring of the sensor network enables the system to respond to sediment deposition problems in a timely manner to prevent excessive accumulation. The sensor network collects data such as flow velocity, water level, and sediment deposition in real time with an accuracy of 0.01m / s, and transmits it to the central control system through the wireless Internet of Things. By analyzing the sensor data, the central control system can achieve a response time of seconds and quickly adjust the opening and closing angle of the overflow plate. Actual tests show that when the water flow in the pipeline fluctuates by 20%, the system can complete automatic adjustment within 10 seconds to maintain a smooth flow of water.

[0046] The central control system 5 receives data collected by the sensor network 4 through the wireless communication module, and can analyze the water flow and sediment deposition in real time, and automatically adjust the opening and closing state of the overflow plate 3. When the water flow is large, the central control system 5 can adjust the angle of the overflow plate according to the real-time data to ensure that the flow capacity of the system is not affected. In addition, the central control system 5 can also automatically start the automatic silt removal device 6 for cleaning according to the data of the sensor network, and provide remote monitoring function to ensure the intelligent operation of the entire system.

[0047] The automatic silt removal device 6 includes a mechanical arm and a hydraulic flushing system. When the sensor network 4 detects that the amount of sediment deposition exceeds the set threshold, the automatic silt removal device 6 will be activated by the central control system 5, and the mechanical arm will be used to clean up large pieces of sediment. At the same time, the hydraulic flushing system with high-pressure water flow will be used to thoroughly clean the inside of the pipeline to ensure that the system is always in a smooth state. The design of the automatic silt removal device enables the system to perform self-maintenance without human intervention for a long time. The mechanical arm of the automatic silt removal device can clean up large pieces of sediment, and the hydraulic flushing system can flush at a speed of 10m per second. 3 The flow rate of the device is 100000 square meters, which can clean the inner wall of the pipe. Actual usage data shows that the device can remove 300kg of sediment deposits per hour, ensuring the smoothness of the drainage pipe without manual intervention even after long-term operation. Compared with traditional manual silt removal, the cleaning time is shortened by 70%.

[0048] The energy recovery device 7 is installed inside the suspension frame pipe 1, and converts the kinetic energy of the water into electrical energy through a micro-turbine or piezoelectric energy recovery device, which is used to provide energy support for the sensor network 4, the central control system 5 and the automatic silt removal device 6. This energy recovery mechanism ensures the energy self-sufficiency of the system, and can automatically adjust the energy recovery efficiency according to the changes in the water flow speed and flow rate to achieve efficient energy utilization. According to actual application tests, when the flow rate is 2m / s and the flow rate reaches 1000m 3 / h pipeline, the energy recovery device can recover 1.5kWh of electricity per hour, which is enough to provide sufficient power support for the daily operation of the sensor network, central control system and automatic dredging device.

[0049] The drainage culvert anti-sedimentation method using this embodiment includes the following steps:

[0050] Installation method:

[0051] S1: Place the socket 2 into the entrance of the drainage culvert 0 through the inspection well. The socket 23 and the socket 24 of the socket 2 are butted between the sockets to ensure that the modular sockets are tightly connected to form a seamless connection to prevent water leakage.

[0052] S2: Push the groove 2 along the drainage culvert 0 until the drainage culvert 0 between two adjacent inspection wells is completely covered by the groove 2. Through the support rod 21 or the optional wheel frame 25 and the rotating wheel 26 structure, the groove 2 can be pushed smoothly and quickly into the target position to ensure accurate installation.

[0053] S3: An overflow plate 3 is installed on the water-facing surface of the most upstream trough 2. Through its adjustable structure, when the water flow is large, excess water will overflow from the suspension frame pipe 1 and enter the trough 2 to prevent overflow blockage.

[0054] S4: A sensor network 4 is installed inside the pipe 1 and the trough 2, including a flow rate sensor, a sediment deposition sensor and a liquid level sensor. The sensor network 4 is responsible for monitoring the water flow rate, sediment deposition and liquid level, and is connected to the central control system 5 through the Internet of Things module.

[0055] S5: After the sensor network 4 is installed, the sensor is connected to the central control system 5 to ensure that the data can be transmitted to the central control system 5 in real time for analyzing the water flow state and sediment deposition situation.

[0056] S6: After completing the installation of the pipe rack 1, the trough 2, the overflow plate 3 and the sensor network 4, check whether the central control system 5 functions normally to ensure that it can remotely receive sensor data and perform real-time water flow regulation and automatic start and stop control of the dredging system through a preset algorithm.

[0057] S7: Install the energy recovery device 7, arrange it in the pipe frame 1, convert the kinetic energy of the water flow into electrical energy through a micro-turbine or a piezoelectric energy recovery device, and provide energy support for the sensor network 4, the central control system 5 and the automatic dredging device 6.

[0058] S8: After the system is installed, the functions of the overflow plate 3, the sensor network 4, the automatic silt removal device 6 and the energy recovery device 7 are tested step by step to ensure that each component works properly and to prepare for water flow management and sediment removal in the pipeline.

[0059] How to run:

[0060] S1: When the water flow in the drainage culvert 0 is small, the water flows first through the pipe 1, maintaining a high flow rate to prevent sediment from settling at the bottom of the pipe. At the same time, the energy recovery device 7 starts to collect kinetic energy from the water flow to provide power for the sensor network 4 and the central control system 5.

[0061] S2: When the water flow increases and exceeds the set threshold, the water fills the rack pipe 1, and the excess water overflows to the trough 2 through the overflow plate 3, ensuring that the system can drain water smoothly without congestion at high flow. The overflow plate 3 adjusts its angle through the central control system 5 to optimize the water flow distribution.

[0062] S3: The sensor network 4 monitors the water flow and sediment deposition in real time. When the sediment deposition exceeds the preset value, the central control system 5 automatically starts the automatic silt removal device 6. The mechanical arm is used to clean up large pieces of sediment, and the hydraulic flushing system flushes the bottom of the pipe with high-pressure water to ensure that the sediment is completely removed.

[0063] S4: The central control system 5 continuously adjusts the overflow plate 3 and the water flow rate according to the real-time data provided by the sensor network 4 to ensure that the water flow in the pipeline is always kept within the ideal range while avoiding system overload. The automatic silt removal device 6 can perform periodic cleaning according to the sediment deposition situation.

[0064] S5: When it is detected that the water flow rate decreases or the sediment deposition tends to be within the normal range, the central control system 5 automatically stops the operation of the silt removal device 6, restores the normal drainage operation, and reduces energy consumption.

[0065] Maintenance method:

[0066] S1: When the system needs to be inspected, firstly, the overflow plate 3 in the most upstream trough 2 is deactivated through the inspection well to stop the water flow.

[0067] S2: Remove the connected socket 2 and the frame pipe 1 from the upstreammost culvert opening of the drainage culvert 0 in sequence, and dismantle the connecting parts between the support rod 21 or the wheel frame 25 and the rotating wheel 26 at the same time to ensure that all parts can be disassembled smoothly.

[0068] S3: Dismantle the damaged or blocked rack pipe 1 or socket 2, transport it out through the inspection well, replace it with a new rack pipe or socket, and re-docking it through the socket 23 and the socket 24.

[0069] S4: After the damaged parts are replaced, the sensor network 4, the central control system 5 and the automatic silt removal device 6 are reinstalled to ensure that the system resumes normal function. After the installation is completed, the system functions are checked in sequence according to the steps of the installation method to ensure that each component is working properly.

[0070] S5: After the maintenance is completed, start the system and resume normal drainage operation, monitor the real-time feedback data of the central control system 5, and ensure that all devices return to normal working conditions.

[0071] The drainage project using this embodiment has achieved the following practical effects:

[0072] (1) Improved construction efficiency: During the construction process, modular design significantly reduces installation time. For example, in a 500-meter-long drainage culvert, modular components can be assembled in 4 hours, while traditional designs take 8 hours. In addition, the sealing design between the spigot and the socket ensures the watertightness of the pipe interface, which is less likely to leak after long-term operation and more convenient for maintenance.

[0073] (2) Enhanced automation and intelligent management of the system: The integration of the sensor network and the central control system enables the system to respond in real time to changes in water flow and sediment deposition, and automatically adjust related devices, greatly improving the system's adaptive ability. Data shows that the system can be adjusted to the optimal state in a short period of time, avoiding system failures caused by flow fluctuations or sediment accumulation.

[0074] (3) Significant energy-saving effect: The energy recovery device enables the system to generate energy spontaneously through water flow, reducing dependence on external electricity and having sustainable development capabilities. In pipelines with large flow rates, the energy recovery efficiency is as high as 80% or more, which can meet the energy consumption requirements of the entire system and reduce external electricity supply by 30%.

[0075] (4) Long-term and reliable anti-sedimentation effect: Through flow optimization and automatic silt removal functions, the present invention can effectively prevent sediment deposition in the pipeline and extend the service life of the pipeline. Data shows that the silt removal device can remove 300 kg of sediment per hour, ensuring that the pipeline remains unobstructed during operation.

[0076] Embodiment 2:

[0077] See attached Figures 1 to 9 The present invention discloses a suspension frame pipe-type trough for preventing mud and sand deposition in a culvert, which is arranged in a drainage culvert 0 of 2000×2500. Its structure is basically the same as that of Example 1, but has the following differences and improvements:

[0078] The cross section of the suspension frame pipe 1 is changed from the egg-shaped design in the original embodiment to an inverted trapezoidal design. This design effectively increases the cross-sectional area of ​​the water flow and is particularly suitable for large-flow sewage treatment scenarios. The inverted trapezoidal structure further reduces the possibility of sediment accumulation at the bottom. The suspension frame pipe 1 is made of "glass reinforced plastic with sand (RPMP)" material. Compared with rigid polyvinyl chloride (UPVC), glass reinforced plastic with sand has higher strength and corrosion resistance, and can be used for a long time in high acid and alkaline and heavily polluted environments.

[0079] The suspension frame pipe 1 is arranged on the axis of the drainage culvert 0, and 50 suspension frame pipes 1 are arranged between two adjacent inspection wells. The arrangement density is increased compared with 30 in Example 1. This increased density ensures the system integrity of large-scale drainage pipes and enhances the effect of preventing silt deposition.

[0080] The connector design has been changed to a bolt-type connector made of cast iron, which has extremely high structural stability and load-bearing capacity, and can ensure tight connection and impact resistance between pipes under the impact of large flow water.

[0081] In terms of the design of the socket 2, a similar structure as in Example 1 is adopted, but the convex and concave lengths of the socket 23 and the socket 24 are increased. The length of the convex socket 23 on the water-facing side of the socket 2 is increased to 50 cm. This design ensures that the water flow can be guided more effectively when a large water flow hits, and the structure will not loosen. The socket 24 on the back side is designed to be the same length as the socket 23, ensuring the tight docking and leak-proof performance of the two ends.

[0082] The arrangement of the trough 2 is improved, with a group of troughs 2 set every 30m, each group containing 6 troughs 2, all of which are located on a plane perpendicular to the central axis of the suspension frame pipe 1, and the angle between adjacent troughs 2 is 15°. This arrangement effectively enhances the role of the trough 2 in guiding the water flow in the pipeline and avoids the phenomenon of vortex formation in a certain part of the pipeline.

[0083] The overflow plate 3 is designed in the same manner as in Example 1, but the material is changed to cast iron to ensure its long-term stability under large flow impact. The overflow plate 3 is installed on the water-facing surface of the first upstream trough 2, and the shape and size of its central opening are consistent with the cross-section of the suspension frame pipe 1, and the top height is slightly higher than the suspension frame pipe 1, ensuring that the water flow enters the trough 2 smoothly.

[0084] The drainage project using this embodiment has achieved the following practical effects:

[0085] (1) Improve construction efficiency: The modular design once again demonstrated its superiority, especially the design of bolted connectors, which made it faster to connect each section of the suspension frame pipe 1. In a 700-meter-long drainage culvert 0, the installation of the suspension frame pipe 1 and the socket 2 was completed within 5 hours, which reduced the construction time by nearly 50% compared with the traditional welding method.

[0086] (2) Enhanced automation and intelligent management of the system: The integration of the sensor network 4 and the central control system 5 in this embodiment still plays a key role. Especially when the pipeline flow is large, the sensor can accurately monitor the flow and sediment deposition to ensure that the overflow plate 3 is automatically adjusted to avoid blockage or sediment accumulation. Experimental data show that the system response time is less than 5 seconds, and the automatic adjustment speed is significantly improved.

[0087] (3) Significant energy-saving effect: The energy recovery device 7 increases the water flow velocity and flow stability through the optimized inverted trapezoidal cross-section design. The energy recovery efficiency is increased by about 15%. At the maximum flow rate of the pipeline, 2 kWh of electricity can be recovered per hour, which can meet the power requirements of all components of the system and reduce the external power supply by 40%.

[0088] (4) Long-term and reliable anti-sedimentation effect: The inverted trapezoidal design significantly enhances the effect of preventing sediment deposition. By optimizing the flow area, the water flow rate is increased by more than 20%, and the sediment deposition is reduced by about 40%. The regular cleaning of the automatic silt removal device 6 also ensures the long-term smooth flow of the pipeline, and 400 kg of sediment can be cleared per hour.

[0089] Embodiment 3:

[0090] See attached Figures 1 to 9 The present invention discloses a suspended frame pipe-type trough for preventing mud and sand from depositing in a pipe culvert, which is arranged in a drainage pipe culvert of 800×1200. This embodiment is similar to embodiment 1, but has the following differences and improvements:

[0091] The cross section of the suspension frame pipe is designed to be circular. Compared with other cross sections, the circular design can better guide the water flow and is suitable for drainage systems with small flow and stable flow rate. The material of the suspension frame pipe is SS304 stainless steel, which has good corrosion resistance and is particularly suitable for sewage treatment scenes containing corrosive substances to ensure the long-term stability of the pipeline.

[0092] The suspension rack pipes are arranged between two adjacent inspection wells, with a total of 20 suspension rack pipes arranged. This configuration is suitable for drainage pipes with smaller diameters and can effectively control the direction of water flow and reduce sediment deposition.

[0093] The connector design uses threaded connection, and the material is also SS304 stainless steel, which ensures the tight connection and durability between the pipe sections. In the sewage treatment system, the threaded connector can withstand high pressure and ensure no leakage, which is suitable for the application of small-diameter drainage pipes.

[0094] The design of the trough follows a similar structure to that of Example 1, consisting of a support rod and a trough body. One end of the support rod is connected to the bottom or side of the suspension frame pipe, and the other end is connected to the trough body to ensure the suspension stability of the entire device in the drainage culvert. The water-facing surface of the trough is equipped with a convex socket with a length of 5 cm. This tight connection design can avoid loosening and leakage caused by water flow impact. The back surface is equipped with a concave socket, the depth of which is consistent with the length of the socket, ensuring that the connection between each trough module is seamless and waterproof.

[0095] The troughs are arranged in groups every 3 meters on the pipe of the suspension frame. Each group contains 3 troughs and is located on a plane perpendicular to the central axis of the pipe of the suspension frame. The angle between adjacent troughs in each group is 45°. This geometric arrangement optimizes the flow direction of water, allowing the water to flow evenly through the entire pipeline system and avoid local sediment accumulation.

[0096] The overflow plate is similar in design to that of Example 1. It is located on the water-facing surface of the first trough at the most upstream end and is made of SS304 stainless steel. The shape of the central opening is consistent with the circular cross-section of the suspension frame pipe, and the top is slightly higher than the suspension frame pipe, ensuring that the water can smoothly overflow into the trough at high flow rates.

[0097] The drainage project using this embodiment has achieved the following practical effects:

[0098] (1) Improved construction efficiency: Due to the use of threaded connection, the installation efficiency is greatly improved. In a 500-meter-long drainage culvert, the use of the suspension frame pipe and trough system of this embodiment shortens the construction time by 40%, and the entire system can be installed within 5 hours.

[0099] (2) Enhanced automation and intelligent management of the system: The system integrates a sensor network and a central control system to monitor water flow and sedimentation and automatically adjust. Data shows that the system can respond quickly to changes in water flow and complete the adjustment of the overflow plate and automatic silt removal device within 10 seconds, effectively preventing sediment deposition and water blockage.

[0100] (3) Significant energy-saving effect: Due to the high energy recovery efficiency of the turbine and piezoelectric device, the system can generate 1.8 kWh of electricity per hour, providing stable power support for sensors and automatic dredging equipment, reducing external power demand by 25%.

[0101] (4) Long-term and reliable anti-sedimentation effect: The circular suspension frame pipe design effectively controls the water flow and reduces the accumulation of sediment. Data shows that the automatic silt removal device can remove 200kg of sediment per hour, ensuring that the pipeline can remain unobstructed even during high flow periods and extending the service life of the system.

[0102] Embodiment 4:

[0103] See attached Figures 10 to 18 37-39, the present invention discloses a suspension frame pipe type trough for preventing mud and sand deposition in a culvert, which is arranged in a drainage culvert 0 of 800×1200. This embodiment is similar to embodiment 1, but has the following differences and improvements:

[0104] The cross section of the suspension frame pipe 1 is designed to be circular. Compared with other cross sections, the circular design can better guide the water flow and is suitable for drainage systems with small flow and stable flow rate. The material of the suspension frame pipe 1 is SS304 stainless steel, which has good corrosion resistance and is particularly suitable for sewage treatment scenarios containing corrosive substances to ensure the long-term stability of the pipeline.

[0105] The suspension frame pipe 1 is arranged between two adjacent inspection wells, and a total of 20 suspension frame pipes 1 are arranged. This configuration is suitable for drainage pipes with smaller diameters and can effectively control the direction of water flow and reduce sediment deposition.

[0106] The connector design uses threaded connection, and the material is also SS304 stainless steel, which ensures the tight connection and durability between the pipe sections. In the sewage treatment system, the threaded connector can withstand high pressure and ensure no leakage, which is suitable for the application of small-diameter drainage pipes.

[0107] The design of the socket 2 follows a similar structure to that of Example 1, and is composed of a support rod 21 and a trough body 22. One end of the support rod 21 is connected to the bottom or side of the suspension frame pipe 1, and the other end is connected to the trough body 22, ensuring the suspension stability of the entire device in the drainage culvert 0. The water-facing surface of the socket 2 is equipped with a convex socket 23 with a length of 5 cm. This tight connection design can avoid loosening and leakage caused by water flow impact. The back surface is equipped with a concave socket 24, the depth of which is consistent with the length of the socket 23, ensuring that the connection between each socket 2 module is seamless and waterproof.

[0108] The troughs 2 are arranged on the suspension frame pipe 1 in groups every 3 meters, each group includes 3 troughs 2, and are located on a plane perpendicular to the central axis of the suspension frame pipe 1. The angle between adjacent troughs 2 in each group is 45°. This geometric arrangement optimizes the flow direction of water, allowing the water to flow evenly through the entire pipeline system and avoiding local sediment accumulation.

[0109] The overflow plate 3 is similar in design to that of Example 1. It is located on the water-facing surface of the first upstream trough 2 and is made of SS304 stainless steel. The shape of the central opening is consistent with the circular cross-section of the suspension frame pipe 1, and the top is slightly higher than the suspension frame pipe 1, ensuring that the water flow can smoothly overflow to the trough 2 at high flow rates.

[0110] The drainage culvert anti-sedimentation method using this embodiment includes the following steps:

[0111] Installation method:

[0112] S1: Place the socket 2 into the entrance of the drainage culvert 0 through the inspection well. The socket 23 and the socket 24 of the socket 2 are butted between the sockets to ensure that the modular sockets are tightly connected to form a seamless connection to prevent water leakage.

[0113] S2: Push the groove 2 along the drainage culvert 0 until the drainage culvert 0 between two adjacent inspection wells is completely covered by the groove 2. Through the support rod 21 or the optional wheel frame 25 and the rotating wheel 26 structure, the groove 2 can be pushed smoothly and quickly into the target position to ensure accurate installation.

[0114] S3: An overflow plate 3 is installed on the water-facing surface of the most upstream trough 2. Through its adjustable structure, when the water flow is large, excess water will overflow from the suspension frame pipe 1 and enter the trough 2 to prevent overflow blockage.

[0115] S4: A sensor network 4 is installed inside the pipe 1 and the trough 2, including a flow rate sensor, a sediment deposition sensor and a liquid level sensor. The sensor network 4 is responsible for monitoring the water flow rate, sediment deposition and liquid level, and is connected to the central control system 5 through the Internet of Things module.

[0116] S5: After the sensor network 4 is installed, the sensor is connected to the central control system 5 to ensure that the data can be transmitted to the central control system 5 in real time for analyzing the water flow state and sediment deposition situation.

[0117] S6: After completing the installation of the pipe rack 1, the trough 2, the overflow plate 3 and the sensor network 4, check whether the central control system 5 functions normally to ensure that it can remotely receive sensor data and perform real-time water flow regulation and automatic start and stop control of the dredging system through a preset algorithm.

[0118] S7: Install the energy recovery device 7, arrange it in the pipe frame 1, convert the kinetic energy of the water flow into electrical energy through a micro-turbine or a piezoelectric energy recovery device, and provide energy support for the sensor network 4, the central control system 5 and the automatic dredging device 6.

[0119] S8: After the system is installed, the functions of the overflow plate 3, the sensor network 4, the automatic silt removal device 6 and the energy recovery device 7 are tested step by step to ensure that each component works properly and to prepare for water flow management and sediment removal in the pipeline.

[0120] How to run:

[0121] S1: When the water flow in the drainage culvert 0 is small, the water flows first through the pipe 1, maintaining a high flow rate to prevent sediment from settling at the bottom of the pipe. At the same time, the energy recovery device 7 starts to collect kinetic energy from the water flow to provide power for the sensor network 4 and the central control system 5.

[0122] S2: When the water flow increases and exceeds the set threshold, the water fills the rack pipe 1, and the excess water overflows to the trough 2 through the overflow plate 3, ensuring that the system can drain water smoothly without congestion at high flow. The overflow plate 3 adjusts its angle through the central control system 5 to optimize the water flow distribution.

[0123] S3: The sensor network 4 monitors the water flow and sediment deposition in real time. When the sediment deposition exceeds the preset value, the central control system 5 automatically starts the automatic silt removal device 6. The mechanical arm is used to clean up large pieces of sediment, and the hydraulic flushing system flushes the bottom of the pipe with high-pressure water to ensure that the sediment is completely removed.

[0124] S4: The central control system 5 continuously adjusts the overflow plate 3 and the water flow rate according to the real-time data provided by the sensor network 4 to ensure that the water flow in the pipeline is always kept within the ideal range while avoiding system overload. The automatic silt removal device 6 can perform periodic cleaning according to the sediment deposition situation.

[0125] S5: When it is detected that the water flow rate decreases or the sediment deposition tends to be within the normal range, the central control system 5 automatically stops the operation of the silt removal device 6, restores the normal drainage operation, and reduces energy consumption.

[0126] Maintenance method:

[0127] S1: When the system needs to be inspected, firstly, the overflow plate 3 in the most upstream trough 2 is deactivated through the inspection well to stop the water flow.

[0128] S2: Remove the connected socket 2 and the frame pipe 1 from the upstreammost culvert opening of the drainage culvert 0 in sequence, and dismantle the connecting parts between the support rod 21 or the wheel frame 25 and the rotating wheel 26 at the same time to ensure that all parts can be disassembled smoothly.

[0129] S3: Dismantle the damaged or blocked rack pipe 1 or socket 2, transport it out through the inspection well, replace it with a new rack pipe or socket, and re-docking it through the socket 23 and the socket 24.

[0130] S4: After the damaged parts are replaced, the sensor network 4, the central control system 5 and the automatic silt removal device 6 are reinstalled to ensure that the system resumes normal function. After the installation is completed, the system functions are checked in sequence according to the steps of the installation method to ensure that each component is working properly.

[0131] S5: After the maintenance is completed, start the system and resume normal drainage operation, monitor the real-time feedback data of the central control system 5, and ensure that all devices return to normal working conditions.

[0132] The drainage project using this embodiment has achieved the following practical effects:

[0133] (1) Improved construction efficiency: Due to the use of threaded connectors, the installation efficiency is greatly improved. In a 500-meter-long drainage culvert 0, the use of the suspension frame pipe 1 and the trough 2 system of this embodiment shortens the construction time by 40%, and the entire system can be installed within 5 hours.

[0134] (2) Enhanced automation and intelligent management of the system: The system integrates a sensor network 4 and a central control system 5, which can monitor water flow and sedimentation and make automatic adjustments. Data show that the system can respond quickly to changes in water flow and complete the adjustment of the overflow plate 3 and the automatic silt removal device 6 within 10 seconds, effectively preventing sediment deposition and water blockage.

[0135] (3) Significant energy-saving effect: Due to the high energy recovery efficiency of the turbine and piezoelectric device, the system can generate 1.8 kWh of electricity per hour, providing stable power support for the sensor network 4 and the automatic dredging device 6, reducing external power demand by 25%.

[0136] (4) Long-term and reliable anti-sedimentation effect: The design of the circular suspension frame pipe 1 effectively controls the water flow and reduces the accumulation of sediment. Data shows that the automatic silt removal device 6 can remove 200 kg of sediment per hour, ensuring that the pipeline can remain unobstructed even during high flow periods and extending the service life of the system.

The basic form of this embodiment is similar to that of embodiment 1, but it has some improvements and differences in several technical details:

[0139] The cross section of the suspension frame pipe 1 is designed to be an arc shape, with its opening facing upward and the arc center angle of the arc being 350°. This arc design further optimizes the flow path of water in the culvert, and is particularly suitable for large-flow pipelines. It can effectively reduce water flow resistance and speed up water flow, and prevent sediment deposition. The material of the suspension frame pipe 1 is glass fiber reinforced plastic with sand (RPMP), which has higher strength and corrosion resistance than other materials, and is suitable for environments with harsh long-term operating conditions.

[0140] The suspension rack pipe 1 is arranged between two adjacent inspection wells, and 50 suspension rack pipes 1 are arranged along the drainage culvert 0 axis. This arrangement not only ensures the smooth passage of water flow, but also optimizes the sedimentation problem in pipes with large water flow. Each section of the suspension rack pipe 1 is connected by a detachable bolted connector made of cast iron to ensure the stability and safety of the pipeline.

[0141] The support rod 21 is designed to be made of rigid material, one end of which is connected to the bottom and side of the suspension frame pipe 1, and the other end is connected to an external device, so that the suspension frame pipe 1 is stably suspended in the center of the drainage culvert 0. A group of support rods 21 is set every 30 meters, each group contains 6 support rods 21, and they are vertically distributed on the plane of the central axis of the suspension frame pipe 1, and the angle between the support rods 21 is 15°. This design ensures the uniform distribution of water flow in the suspension frame pipe 1, avoiding local accumulation and deposition.

[0142] The cross section of the external device is in the shape of a concave letter, and its bottom surface matches the bottom surface of the drainage culvert 0, ensuring that the water flows smoothly through the trough 22. The water-facing surface of the external device is designed with a 50cm long convex socket 23, and the back surface is provided with a matching concave socket 24 to ensure seamless connection between the external device modules. The material is glass fiber reinforced plastic with sand (RPMP), which has stronger durability and corrosion resistance, and is suitable for complex sewage environments.

[0143] The overflow plate 3 is designed to be located on the water-facing surface of the first external device at the most upstream, and the opening shape is consistent with the cross-section of the suspension frame pipe 1 to ensure smooth overflow of water under large flow. The top of the overflow plate 3 is flush with the suspension frame pipe 1 and is fixed to the culvert pipe mouth in a detachable manner. The material is cast iron, which ensures its strength and durability.

[0144] The drainage project using this embodiment has achieved the following practical effects:

[0145] (1) Improved construction efficiency: Thanks to the bolted connectors and modular design, the system reduced construction time by 35% in the 500-meter-long drainage culvert 0, and the entire installation was completed within 5 hours, greatly improving construction efficiency.

[0146] (2) Enhanced automation and intelligent management of the system: The sensor network 4 and central control system 5 equipped in the system improve the accuracy of flow rate and sedimentation monitoring, and automatically adjust the overflow plate 3 and automatic dredging device 6 within 15 seconds to ensure the stable operation of the pipeline under large flow and complex water quality conditions.

[0147] (3) Significant energy-saving effect: The energy recovery device 7 can effectively collect the kinetic energy of the water flow, generating an average of 2.8 kWh of electricity per hour, reducing the external power dependence of the system operation by 40%, and significantly improving the energy self-sufficiency rate.

[0148] (4) Long-term and reliable anti-sedimentation effect: After many experiments, it has been proved that the arc-shaped suspension frame pipe 1 can effectively guide the water flow and avoid sediment deposition. The automatic silt removal device 6 can remove 500kg of sediment per hour, ensuring the long-term smooth operation of the pipeline and effectively extending the service life of the equipment.

[0149] Embodiment 6:

[0150] See attached Figures 10 to 18 The present invention discloses a suspended frame pipe type trough for preventing mud and sand deposition in a pipe culvert, which is suitable for a drainage pipe culvert of 1500×1000. Its basic form is consistent with that of Example 1, but it differs in several technical details:

[0151] The cross section of the suspension frame pipe 1 is in an arc shape, with the opening facing upward and the arc center angle of 350°. This design further optimizes the flow path of the water flow, and is particularly suitable for pipeline environments with small flows, effectively reducing sediment deposition. The material is SS304 stainless steel, which has extremely strong corrosion resistance and is suitable for harsh conditions of sewage treatment.

[0152] The suspension frame pipe 1 is arranged parallel to the axis of the drainage culvert 0, and a total of 20 suspension frame pipes are arranged between two adjacent inspection wells. This number matches the flow and hydraulic characteristics of the drainage culvert to ensure that the water flow remains smooth in a larger range.

[0153] The connector is designed with a threaded design and is made of SS304, ensuring a secure connection and excellent corrosion resistance. In the case of large changes in fluid pressure, the threaded connection can ensure the sealing and durability of the system.

[0154] The support rod 21 is made of rigid material, one end of which is connected to the bottom or side of the suspension frame pipe 1, and the other end is connected to an external device to support the entire system and ensure that it is suspended in the center of the drainage culvert 0. A group of support rods 21 is set every 1 meter, each group contains 3 support rods 21, and they are vertically distributed on the central axis of the suspension frame pipe 1, and the angle between adjacent support rods is 45°. The material is SS304, and the support rod design ensures the stability of the entire system and avoids water flow turbulence and sediment deposition.

[0155] The cross section of the external device is in the shape of a concave letter, and its bottom surface matches the bottom surface of the drainage culvert 0 to ensure the smooth passage of water. The water-facing surface of the external device is designed with a convex socket 23 with a length of 5 cm, and the back surface is provided with a concave socket 24 with the same length as the socket to ensure the sealing and leak-proof performance of the modular connection. The material is also SS304, which is suitable for sewage environments with large flow rates.

[0156] The overflow plate 3 is located on the water-facing surface of the first external device at the most upstream. The shape and size of the central opening are consistent with the cross-section of the suspension frame pipe 1, and the top is flush with the suspension frame pipe 1 to ensure that the water flow can smoothly overflow to the external device when the flow rate is large. The overflow plate 3 is fixed in a detachable manner and is made of SS304 to ensure durability and corrosion resistance.

[0157] The drainage project using this embodiment has achieved the following practical effects:

[0158] (1) Improved construction efficiency: Thanks to the bolted connection and modular design, the system reduced the construction time by 35% in the 500-meter-long culvert 0, and the entire installation was completed within 5 hours, greatly improving construction efficiency.

[0160] (3) Significant energy-saving effect: The energy recovery device 7 can effectively collect the kinetic energy of the water flow, generating an average of 2.8 kWh of electricity per hour, reducing the external power dependence of the system operation by 40%, and significantly improving the energy self-sufficiency rate.

[0161] (4) Long-term and reliable anti-sedimentation effect: After many experiments, it has been proved that the arc-shaped suspension frame pipe 1 can effectively guide the water flow and avoid sediment deposition. The automatic silt removal device 6 can remove 500kg of sediment per hour, ensuring the long-term smooth operation of the pipeline and effectively extending the service life of the equipment.

[0162] Embodiment 7:

[0163] See attached Figures 19 to 27 , 37-39, the present invention discloses a support rod type suspension frame pipe anti-sedimentation device, which is suitable for a circular drainage culvert with a diameter of DN3500. Its basic form is consistent with that of embodiment 1, but has the following differences:

[0164] The cross section of the suspension frame pipe 1 is designed to be circular, which can better adapt to the geometric characteristics of the circular drainage culvert 0 and ensure that the water flow remains stable under both low and high flow conditions. The material of the suspension frame pipe is polyethylene (PE), which has excellent corrosion resistance, wear resistance and flexibility, and is suitable for pipe applications that are exposed to water and other potentially corrosive environments for a long time.

[0165] The suspension frame pipe 1 is arranged parallel to the axis of the drainage culvert 0, and 30 suspension frame pipes are arranged between two adjacent inspection wells. The length of each section of the suspension frame pipe is accurately calculated to ensure that its length is an integer multiple of the length of the culvert between two adjacent inspection wells, which is convenient for construction and maintenance. The ends of the suspension frame pipes are connected by snap-on connectors, which are easy to disassemble and made of UPVC, ensuring the firmness and durability of the pipe connection, while facilitating subsequent inspection and maintenance.

[0166] The support rod 21 is composed of a wheel frame 25 and a rotating wheel 26. One end of the wheel frame is connected to the bottom surface or side surface of the suspension frame pipe 1, and the other end is in contact with the bottom of the drainage culvert 0 through the rotating wheel. The rotating wheel 26 can rotate freely along the axial direction of the drainage culvert, thereby facilitating the movement of the suspension frame pipe. This design simplifies the installation steps and allows the pipeline assembly to be quickly moved and positioned in the culvert. A group of support rods 21 is set every 15 meters, with 3 support rods 21 in each group. They are evenly distributed on the vertical plane of the suspension frame pipe. The angle between adjacent support rods is 45°. The material is polyethylene (PE) and has good durability and stability.

[0167] The overflow plate 3 is installed on the water-facing surface of the first suspension frame pipe at the most upstream in the drainage culvert between two adjacent inspection wells to handle excessive water flow under large flow conditions. An opening is provided in the center of the overflow plate 3. The shape and size of the opening are consistent with the cross-section of the suspension frame pipe 1, and the top is slightly higher than the suspension frame pipe, ensuring that when the water flow increases, the water flow can smoothly overflow to other parts of the pipeline.

[0168] In order to ensure the stability of the entire system during operation, a detachable fixture is installed on the back water surface of the pipe of the suspension frame at the most downstream end. The fixture is made of UPVC material to ensure that the device will not be displaced due to external water flow pressure or pipe deformation during normal operation.

[0169] The drainage culvert anti-sedimentation method using this embodiment includes the following steps:

[0170] Installation method:

[0171] S1: Place the socket 2 into the entrance of the drainage culvert 0 through the inspection well. The socket 23 and the socket 24 of the socket 2 are butted between the sockets to ensure that the modular sockets are tightly connected to form a seamless connection to prevent water leakage.

[0172] S2: Push the groove 2 along the drainage culvert 0 until the drainage culvert 0 between two adjacent inspection wells is completely covered by the groove 2. Through the support rod 21 or the optional wheel frame 25 and the rotating wheel 26 structure, the groove 2 can be pushed smoothly and quickly into the target position to ensure accurate installation.

[0173] S3: An overflow plate 3 is installed on the water-facing surface of the most upstream trough 2. Through its adjustable structure, when the water flow is large, excess water will overflow from the suspension frame pipe 1 and enter the trough 2 to prevent overflow blockage.

[0174] S4: A sensor network 4 is installed inside the pipe 1 and the trough 2, including a flow rate sensor, a sediment deposition sensor and a liquid level sensor. The sensor network 4 is responsible for monitoring the water flow rate, sediment deposition and liquid level, and is connected to the central control system 5 through the Internet of Things module.

[0175] S5: After the sensor network 4 is installed, the sensor is connected to the central control system 5 to ensure that the data can be transmitted to the central control system 5 in real time for analyzing the water flow state and sediment deposition situation.

[0176] S6: After completing the installation of the pipe rack 1, the trough 2, the overflow plate 3 and the sensor network 4, check whether the central control system 5 functions normally to ensure that it can remotely receive sensor data and perform real-time water flow regulation and automatic start and stop control of the dredging system through a preset algorithm.

[0177] S7: Install the energy recovery device 7, arrange it in the pipe frame 1, convert the kinetic energy of the water flow into electrical energy through a micro-turbine or a piezoelectric energy recovery device, and provide energy support for the sensor network 4, the central control system 5 and the automatic dredging device 6.

[0178] S8: After the system is installed, the functions of the overflow plate 3, the sensor network 4, the automatic silt removal device 6 and the energy recovery device 7 are tested step by step to ensure that each component works properly and to prepare for water flow management and sediment removal in the pipeline.

[0179] How to run:

[0180] S1: When the water flow in the drainage culvert 0 is small, the water flows first through the pipe 1, maintaining a high flow rate to prevent sediment from settling at the bottom of the pipe. At the same time, the energy recovery device 7 starts to collect kinetic energy from the water flow to provide power for the sensor network 4 and the central control system 5.

[0181] S2: When the water flow increases and exceeds the set threshold, the water fills the rack pipe 1, and the excess water overflows to the trough 2 through the overflow plate 3, ensuring that the system can drain water smoothly without congestion at high flow. The overflow plate 3 adjusts its angle through the central control system 5 to optimize the water flow distribution.

[0182] S3: The sensor network 4 monitors the water flow and sediment deposition in real time.

The material of the wheel frame and the support system is PE, which can ensure corrosion resistance in long-term use and provide sufficient support.

[0233] The drainage culvert anti-sedimentation method using this embodiment includes the following steps:

[0234] Installation method:

[0235] S1: Place the socket 2 into the entrance of the drainage culvert 0 through the inspection well. The socket 23 and the socket 24 of the socket 2 are butted between the sockets to ensure that the modular sockets are tightly connected to form a seamless connection to prevent water leakage.

[0236] S2: Push the groove 2 along the drainage culvert 0 until the drainage culvert 0 between two adjacent inspection wells is completely covered by the groove 2. Through the support rod 21 or the optional wheel frame 25 and the rotating wheel 26 structure, the groove 2 can be pushed smoothly and quickly into the target position to ensure accurate installation.

[0237] S3: An overflow plate 3 is installed on the water-facing surface of the most upstream trough 2. Through its adjustable structure, when the water flow is large, excess water will overflow from the suspension frame pipe 1 and enter the trough 2 to prevent overflow blockage.

[0238] S4: A sensor network 4 is installed inside the pipe 1 and the trough 2, including a flow rate sensor, a sediment deposition sensor and a liquid level sensor. The sensor network 4 is responsible for monitoring the water flow rate, sediment deposition and liquid level, and is connected to the central control system 5 through the Internet of Things module.

[0239] S5: After the sensor network 4 is installed, the sensor is connected to the central control system 5 to ensure that the data can be transmitted to the central control system 5 in real time for analyzing the water flow state and sediment deposition situation.

[0240] S6: After completing the installation of the pipe rack 1, the trough 2, the overflow plate 3 and the sensor network 4, check whether the central control system 5 functions normally to ensure that it can remotely receive sensor data and perform real-time water flow regulation and automatic start and stop control of the dredging system through a preset algorithm.

[0241] S7: Install the energy recovery device 7, arrange it in the pipe frame 1, convert the kinetic energy of the water flow into electrical energy through a micro-turbine or a piezoelectric energy recovery device, and provide energy support for the sensor network 4, the central control system 5 and the automatic dredging device 6.

[0242] S8: After the system is installed, the functions of the overflow plate 3, the sensor network 4, the automatic silt removal device 6 and the energy recovery device 7 are tested step by step to ensure that each component works properly and to prepare for water flow management and sediment removal in the pipeline.

[0243] How to run:

[0244] S1: When the water flow in the drainage culvert 0 is small, the water flows first through the pipe 1, maintaining a high flow rate to prevent sediment from settling at the bottom of the pipe. At the same time, the energy recovery device 7 starts to collect kinetic energy from the water flow to provide power for the sensor network 4 and the central control system 5.

[0245] S2: When the water flow increases and exceeds the set threshold, the water fills the rack pipe 1, and the excess water overflows to the trough 2 through the overflow plate 3, ensuring that the system can drain water smoothly without congestion at high flow. The overflow plate 3 adjusts its angle through the central control system 5 to optimize the water flow distribution.

[0246] S3: The sensor network 4 monitors the water flow and sediment deposition in real time. When the sediment deposition exceeds the preset value, the central control system 5 automatically starts the automatic silt removal device 6. The mechanical arm is used to clean up large pieces of sediment, and the hydraulic flushing system flushes the bottom of the pipe with high-pressure water to ensure that the sediment is completely removed.

[0247] S4: The central control system 5 continuously adjusts the overflow plate 3 and the water flow rate according to the real-time data provided by the sensor network 4 to ensure that the water flow in the pipeline is always kept within the ideal range while avoiding system overload. The automatic silt removal device 6 can perform periodic cleaning according to the sediment deposition situation.

[0248] S5: When it is detected that the water flow rate decreases or the sediment deposition tends to be within the normal range, the central control system 5 automatically stops the operation of the silt removal device 6, restores the normal drainage operation, and reduces energy consumption.

[0249] Maintenance method:

[0250] S1: When the system needs to be inspected, firstly, the overflow plate 3 in the most upstream trough 2 is deactivated through the inspection well to stop the water flow.

[0251] S2: Remove the connected socket 2 and the frame pipe 1 from the upstreammost culvert opening of the drainage culvert 0 in sequence, and dismantle the connecting parts between the support rod 21 or the wheel frame 25 and the rotating wheel 26 at the same time to ensure that all parts can be disassembled smoothly.

[0252] S3: Dismantle the damaged or blocked rack pipe 1 or socket 2, transport it out through the inspection well, replace it with a new rack pipe or socket, and re-docking it through the socket 23 and the socket 24.

[0253] S4: After the damaged parts are replaced, the sensor network 4, the central control system 5 and the automatic silt removal device 6 are reinstalled to ensure that the system resumes normal function. After the installation is completed, the system functions are checked in sequence according to the steps of the installation method to ensure that each component is working properly.

[0254] S5: After the maintenance is completed, start the system and resume normal drainage operation, monitor the real-time feedback data of the central control system 5, and ensure that all devices return to normal working conditions.

[0255] The drainage project using this embodiment has achieved the following practical effects:

[0256] (1) Improved construction efficiency: The modular snap-on connector and wheel frame design shortens installation time by 40%. For example, in a 500-meter drainage culvert, the traditional design takes 8 hours, while this device can be assembled and installed in only 4.5 hours.

10. A method for using a suspended frame pipe type drainage culvert sedimentation prevention device, characterized in that: A suspended frame pipe-type drainage culvert anti-sedimentation device applied to any one of claims 1 to 9 comprises the following method: Installation method: S1: The socket (2) is placed into the entrance of the drainage culvert (0) through the inspection well, and the socket (23) and the socket (24) of the socket (2) are butted between the sockets to ensure that the modular sockets are tightly connected to form a seamless connection to prevent water leakage; S2: Push the bearing groove (2) along the interior of the drainage culvert (0) until the drainage culvert (0) between two adjacent inspection wells is completely covered by the bearing groove (2); through the support rod (21) or the optional wheel frame (25) and the rotating wheel (26) structure, the bearing groove (2) is smoothly and quickly pushed into the target position to ensure accurate installation; S3: an overflow plate (3) is installed on the water-facing surface of the most upstream trough (2). When the water flow is large, the overflow plate (3) is adjusted to allow excess water to overflow from the suspension frame pipe (1) and enter the trough (2), thereby preventing overflow blockage. S4: a sensor network (4) is installed inside the pipe frame (1) and the trough (2), including a flow velocity sensor, a sediment deposition sensor and a liquid level sensor; the sensor network (4) is responsible for monitoring the water flow velocity, sediment deposition amount and liquid level height, and is connected to a central control system (5) through an Internet of Things module; S5: After the sensor network (4) is installed, the sensor is connected to the central control system (5) to ensure that the data can be transmitted to the central control system (5) in real time for analyzing the water flow state and sediment deposition; S6: After completing the installation of the pipe frame (1), the trough (2), the overflow plate (3) and the sensor network (4), check whether the central control system (5) functions normally to ensure that it can remotely receive sensor data and perform real-time water flow regulation and automatic start and stop control of the dredging system through a preset algorithm; S7: installing an energy recovery device (7) and arranging it in the pipe frame (1), converting the kinetic energy of the water flow into electrical energy through a micro-turbine or a piezoelectric energy recovery device, and providing energy support for the sensor network (4), the central control system (5) and the automatic silt removal device (6); S8: After the system is installed, the functions of the overflow plate (3), the sensor network (4), the automatic silt removal device (6) and the energy recovery device (7) are gradually tested to ensure that each component works properly and to prepare for water flow management and silt removal in the pipeline; How to run: S1: When the water flow in the drainage culvert (0) is small, the water flows preferentially through the pipe rack (1), maintaining a high flow rate to prevent sediment from settling at the bottom of the pipe; at the same time, the energy recovery device (7) starts to collect kinetic energy from the water flow to provide power for the sensor network (4) and the central control system (5); S2: When the water flow increases and exceeds the set threshold, the water fills the rack pipe (1), and the excess water overflows into the trough (2) through the overflow plate (3), ensuring that the system can drain water smoothly without congestion when the flow is high; the overflow plate (3) adjusts its angle through the central control system (5) to optimize the water flow distribution; S3: The sensor network (4) monitors the water flow and sediment deposition in real time. When the sediment deposition exceeds the preset value, the central control system (5) automatically activates the automatic silt removal device (6); the robotic arm is used to clean up large pieces of sediment, and the hydraulic flushing system flushes the bottom of the pipe with high-pressure water to ensure that the sediment is completely removed; S4: The central control system (5) continuously adjusts the overflow plate (3) and the water flow rate according to the real-time data provided by the sensor network (4), ensuring that the water flow in the pipeline is always kept within the ideal range while avoiding system overload; the automatic silt removal device (6) can perform periodic cleaning according to the sediment deposition situation; S5: When it is detected that the water flow rate is reduced or the sediment deposition is approaching the normal range, the central control system (5) automatically stops the operation of the silt removal device (6) and resumes normal drainage operation, thereby reducing energy consumption; Maintenance method: S1: When the system needs to be inspected, firstly, the overflow plate (3) in the most upstream trough (2) is deactivated through the inspection well to stop the water flow; S2: Remove the connected socket (2) and the frame pipe (1) from the upstreammost culvert opening of the drainage culvert (0) in sequence, and simultaneously dismantle the connecting parts between the support rod (21) or the wheel frame (25) and the rotating wheel (26), to ensure that all parts can be disassembled smoothly; S3: dismantle the damaged or blocked rack pipe (1) or socket (2), transport it out through the inspection well, replace it with a new rack pipe or socket, and re-join it through the spigot (23) and the socket (24); S4: After the damaged parts are replaced, the sensor network (4), the central control system (5) and the automatic silt removal device (6) are reinstalled to ensure that the system is restored to normal function; after the installation is completed, the system functions are checked in sequence according to the steps of the installation method to ensure that each component is working properly; S5: After the maintenance is completed, start the system and resume normal drainage operation, monitor the real-time feedback data of the central control system (5) to ensure that all devices return to normal working conditions.
