Description

Technical Field

[0001] This invention belongs to the technical field of waterway cleaning equipment, and relates to a device that can clean up garbage and silt in roads and agricultural drainage channels, especially a drainage channel cleaning vehicle that can clean and transport silt and garbage in drainage channels. Background Technology

[0002] During the rainy season, when heavy rains occur, urban roads often experience flooding due to inadequate drainage or rainwater accumulating in low-lying areas. Roads become submerged, making it difficult or even impossible for vehicles to pass. One of the causes of urban flooding is blocked drainage channels. Therefore, regularly cleaning drainage channels plays a crucial role in ensuring smooth drainage and reducing urban flooding.

[0003] In the prior art, Chinese patent with publication number CN110747923A discloses a device for diverting and dredging agricultural irrigation ditches, including a body. The body has a working chamber, and the bottom wall of the working chamber has symmetrically arranged through cavities. A collection chamber is arranged between the through cavities. A connecting pipe is fixedly connected between the collection chamber and the top wall of the working chamber. A second hydraulic pipe is arranged on the top wall of the collection chamber, and a first hydraulic pipe is arranged on the top wall of the working chamber. A transverse pipe is arranged on the top walls of the first hydraulic pipe and the second hydraulic pipe. A sludge pumping device for pumping up sludge is arranged between the second hydraulic pipe and the collection chamber.

[0004] Currently, urban areas have relatively few surface drainage channels, with most existing beneath roads. The limited number of drainage outlets or collection points results in insufficient drainage capacity, easily leading to road flooding and preventing the timely collection of large amounts of rainwater. Much rainwater flows into sewage pipes, increasing the total amount and cost of sewage treatment and hindering the full utilization of freshwater resources. Furthermore, the cleaning of a small portion of surface drainage channels relies primarily on manual labor, which suffers from low efficiency and time-consuming processes. Summary of the Invention

The bottom slope of the fourth-level source water collection channels, the third-level main road water collection channels, and the second-level surface regional water collection channels is the same as the road slope.

[0016] Compared with existing technologies, the drainage cleaning vehicle designed in this invention has a reasonable main structure, enabling it to clean, collect, and transport blockages such as fallen leaves, garbage, and silt in drainage channels. This overcomes the shortcomings of low efficiency and long processing time associated with manual cleaning.

[0039] like Figure 3 , 4As shown in Figures 7 and 8, the telescopic breaking plow 3 consists of a plow head 22 and a plow plate box 23. The plow head 22 is installed at the front end of the plow plate box 23, as shown in Figures 7 and 8. Figure 1 As shown, the plowshare 22 is composed of a plowshare inclined plate and a plowshare flat plate combined at an obtuse angle. The plowshare inclined plate has protrusions to facilitate breaking up deposited debris. The plowshare flat plate is kept level with the ground. The plowshare 22 can be replaced after wear. The plowshare box 23 includes an outer plowshare box plate 231, an inner plowshare box plate 232, a plowshare box bottom plate 233, and a front opening 234. Figure 8 As shown, a plow box 23 has a bottom plate 233 at its bottom, which is installed on the upper side of the front end of the inclined conveyor belt 17. Plow box side plates are symmetrically arranged on both sides of the bottom plate 233. Each side plate consists of an outer side plate 231 and an inner side plate 232. A plow box rail groove is provided between the outer side plate 231 and the inner side plate 232. The transmission guard plates 8 on both sides of the inclined conveyor belt 17 are limited in the plow box rail groove. The plow box 23 can extend and retract along the front of the transmission guard plates 8 on both sides of the inclined conveyor belt 17. An "eight"-shaped front opening 234 is provided at the front of the plow box 23, which facilitates the collection of garbage in the waterway. The rear end of the plow box side plate of the plow box 23 is connected to the hydraulic expansion joint 5. Figure 7 , 8 As shown, the hydraulic telescopic joint 5 is equipped with a lower telescopic arm 21 and an upper telescopic arm 24 on each side. The front part of the lower telescopic arm 21 is fixedly connected to the lower end of the outer side plate 231 of the plow plate box 23, and the front end of the upper telescopic arm 24 is fixedly connected to the rear end of the outer side plate 231 of the plow plate box 23.

The hydraulic telescopic joint 5 is equipped with a force feedback system, which is a prior art technology. Excavators or pile drivers are equipped with hydraulic pressure sensors or load sensors. When encountering hard rocks, the resistance increases sharply, and the system automatically stops. Equipping excavators or pile drivers with hydraulic pressure sensors or load sensors is a key technical means to realize the force feedback system. It is used to monitor the working load and hydraulic system status in real time, and to automatically control or warn based on this, so as to improve work efficiency, safety and equipment life.

[0040] The power drive unit uses an independently installed drive motor, which is mounted on the upper rear end of the inner support frame 14. The drive motor is connected to the inner end shaft of the inclined conveyor belt drive wheel 35 of the inclined conveyor belt 17. The drive motor drives the inclined conveyor belt drive wheel 35 to rotate counterclockwise. Figure 10 , 11As shown, an inclined drive belt gear 27 is mounted on the outer end shaft of the inclined conveyor belt drive wheel 35. The inclined drive belt gear 27 meshes with the driven gear 28 of the transverse drive belt. The driven gear 28 of the transverse drive belt adopts a straight bevel gear or bevel gear structure. The driven gear 28 of the transverse drive belt is equipped with steering gear teeth 58 for power steering. The driven gear 28 of the transverse drive belt drives the transverse conveyor belt 15 to transport garbage from the outside to the compartment 1. The two ends of the shaft of the driven gear 28 of the transverse drive belt are respectively limited by the rear support plate 11 and the front support plate 29. The power of the power drive unit may be provided by the rear wheels, such as... Figure 10 As shown, a horizontal drive belt drive gear 52 is mounted on the inner end shaft of the inclined conveyor belt drive wheel 35. The horizontal drive belt drive gear 52 is connected to the intermediate external gear 53 via a transmission chain. An intermediate internal gear 54 is coaxially mounted on the inner side of the intermediate external gear 53. The shafts of the intermediate external gear 53 and the intermediate internal gear 54 are mounted on the lower end of the inner rear vertical beam 40 of the inner support frame 14. When the cleaning section is driven down to the lower end by the lifter 2, the intermediate internal gear 54 meshes with the drive gear 55. A power driven wheel 56 is coaxially mounted on the inner side of the drive gear 55. Figure 1 As shown, the shafts of the drive gear 55 and the driven wheel 56 are mounted at the lower rear end of the carriage 1; Figure 10 As shown, the driven wheel 56 is connected to the driving wheel 57 via a conveyor belt, as... Figure 1 As shown, the drive wheel 57 is mounted coaxially with the rear wheel axle. When the cleaning unit is driven down to the lower end by the lifter 2, the internal gear 54 and the drive gear 55 mesh together. When the drainage cleaning vehicle moves forward, the drive wheel 57 rotates with the rear wheel axle. The drive wheel 57 drives the driven wheel 56 to rotate via the conveyor belt. The drive gear 55, which is coaxial with the driven wheel 56, rotates accordingly. The drive gear 55 drives the internal gear 54 to rotate. The external gear 53, which is coaxial with the internal gear 54, rotates accordingly. The external gear 53 drives the horizontal transmission belt drive gear 52 to rotate via the chain. The horizontal transmission belt drive gear 52 drives the inclined conveyor belt 17 to run. The horizontal transmission belt drive gear 52 and the inclined transmission belt gear 27 rotate coaxially. The inclined transmission belt gear 27 drives the horizontal transmission belt driven gear 28 to rotate, thereby driving the horizontal conveyor belt 15 to run.

[0041] The cleaning method for agricultural irrigation canals, drainage ditches, and other waterways is as follows: Surface drainage channels are regularly cleaned using drainage channel cleaning vehicles to ensure unobstructed drainage; the specific cleaning steps are as follows:

[0042] Step 1: Lowering the excavator to the drainage channel: Activate the hydraulic telescopic device 5. The telescopic excavator 3 tilts and extends downwards. The hydraulic telescopic device 5 is equipped with a force feedback system (equipped with a hydraulic pressure sensor or load sensor). When the agricultural irrigation canal or drainage ditch is constructed of cement, bricks, etc., the telescopic excavator 3 will stop descending when it reaches the bottom of the waterway due to increased resistance, and the telescopic excavator 3 will automatically rise 2-3 cm. When the agricultural irrigation canal or drainage ditch is an excavated trench, the depth to which the telescopic excavator 3 descends to the drainage channel is manually selected.

[0043] Step 2: Waterway garbage cleaning and transportation: The front plow head of the telescopic breaking plow 3 breaks up the silt, fallen leaves, garbage and other sediments deposited in the waterway. The sediments are pushed upward along the telescopic breaking plow 3 through the plow plate box 23 into the inclined conveyor belt 17. The inclined conveyor belt 17 transports the sediments upward to the transverse conveyor belt 15. The sediments are then transported to the carriage 1 via the transverse conveyor belt 15.

[0044] Step 3: Waterway Cleaning and Turning: When the drainage cleaning vehicle moves to the end of a drainage channel, the hydraulic telescopic device 5 controls the telescopic breaking plow 3 to tilt upward and retract. The lifting device 2 of the drainage cleaning vehicle raises the telescopic breaking plow 3 to the upper end face of the drainage channel (the lower end face of the telescopic breaking plow 3 of the cleaning part is 2-3 cm higher than the upper end face of the drainage channel). After the drainage cleaning vehicle turns, clean the remaining waterways according to steps 1-3 until all waterways are cleaned.

[0045] Example 2:

[0046] The drainage cleaning vehicle described in Example 1 is equipped with a tilting unit 4 to form a water collection channel cleaning vehicle, which is used for cleaning urban road water collection channels 62; the tilting unit 4 includes a tilting outer shell and a tilting inner frame, and a tilting lifting head 45 is provided at the front of the tilting inner frame, such as... Figure 12 As shown, the tilting head 45 has a smooth, sloping structure that slopes upwards from the front outer end to the rear inner end. A tilting head fixing plate 61 is provided on the inner wall of the tilting head 45, as... Figure 5 As shown, the flip head fixing plate 61 is fixedly connected to the outer front wall of the inner lower crossbeam 37 of the inner support frame 14, and the rear end of the inner lower crossbeam 37 is fixedly connected to the front end of the inner inclined beam 43; as Figure 12 As shown, the outer rear end of the tilting head 45 is connected to the front end of the tilting vertical plate, and the rear part of the tilting vertical plate is fixedly connected to the outer end of the tilting front fixed plate 20. The upper end of the tilting front fixed plate 20 is connected to the outer support frame 7 and the inner support frame 14; the rear end of the tilting vertical plate is connected to the outer front end of the tilting return head 60, and the tilting return head 60 has a smooth slope structure that slopes downward from the inner front end to the outer rear end; as shown... Figure 5 , 10As shown, the upper end of the flip-up inner frame is fixedly connected to the inner end of the upper cover plate 18 (the upper edge of the flip-up inner frame and the inner edge of the upper cover plate 18 have the same shape). The upper cover plate 18 is the upper shell plate of the flip-up outer shell. A front flip-up plate 44 is provided at the front end of the flip-up outer shell. The inner wall of the front flip-up plate 44 is fixedly connected to the front end of the inner lower crossbeam 37. The upper end of the front flip-up plate 44 is fixedly connected to the front end of the upper cover plate 18. The outer wall of the front flip-up plate 44 is fixedly connected to the front end of the flip-up outer side plate 59. The flip-up outer side plate 59 is fixedly connected to the outer end of the upper cover plate 18. The flip-up outer side plate 59 is connected to the flip-up inner frame. The gap between the vertical plates of the frame forms a vertical retaining channel for the flipping section. The width of this vertical retaining channel is greater than the thickness of the rainwater cover 65 installed on the upper part of the water collection channel 62. An inclined protrusion 81 is provided on the middle and rear part of the inner wall of the outer flipping plate 59. The inclined protrusion 81 is an arc-shaped gentle slope that slopes inward and backward. The inclined protrusion 81 assists the rainwater cover 65, which is being raised, in changing from an upright state to a horizontal state. The rear end of the outer flipping plate 59 is fixedly connected to the outer end of the rear flipping plate 39, and the upper end of the rear flipping plate 39 is fixedly connected to the rear end of the upper cover plate 18. Figure 1 As shown, the upper end face of the rear end of the upper cover plate 18 is fixedly connected to the lower end of the support connecting plate 13. A monitoring camera is installed on the rear side wall of the front flip plate 44 of the flipping part 4. The monitoring camera is used to observe the distance between the lower end of the flipping part 4 and the water collection channel when the cleaning part is lowered. The image display of the monitoring camera is set in the cab.

[0047] like Figure 13 , 14 As shown, the water collection channel 62 is installed on both sides of the urban road. A cover plate shaft groove 63 is provided on one side of the upper end of the water collection channel 62. The cover plate shaft groove 63 is located on the outer side of the road. A cover plate shaft 67 for a rainwater cover 65 is installed in the cover plate shaft groove 63. The width of the groove 63 is larger than the diameter of the cover plate shaft 67 to facilitate the installation of the cover plate shaft 67 into the cover plate shaft groove 63. Figure 14As shown, with the axis of the cover plate shaft groove 63 as the vertex, the angle between the upper edge of the cover plate shaft groove 63 and the vertical plane containing the axis of the cover plate shaft groove 63 is the upper deflection angle 'a' of the groove opening; the angle between the lower edge of the cover plate shaft groove 63 and the horizontal plane containing the axis of the cover plate shaft groove 63 is the lower deflection angle 'b' of the groove opening. The angle value of the upper deflection angle 'a' of the groove opening is 0-3 degrees larger than the angle value of the lower deflection angle 'b' of the groove opening. The lower intersection point of the connection between the cover plate shaft 67 and the main plate of the rainwater cover 65 is the lower intersection point of the shaft and the cover plate. With the axis of the cover plate shaft 67 as the vertex, the angle between the horizontal plane containing the axis of the cover plate shaft 67 and the lower intersection point of the shaft and the cover plate is the axis deflection angle. The deflection angle is equal to the lower deflection angle b of the groove. The angle between the upper deflection angle a and the lower deflection angle b of the groove limits the angle so that the cover shaft 67 is not easy to detach from the cover shaft groove 63. A cover groove 64 is provided on the other side of the upper end of the water collection channel 62. The cover groove 64 is used to support the rainwater cover 65. When the rainwater cover 65 is horizontally installed on the upper end of the water collection channel 62, the cover shaft groove 63 and the cover groove 64 jointly support the rainwater cover 65. The main body of the rainwater cover 65 is provided with water permeable holes 66. The water permeable holes 66 are used to collect rainwater from the road and enter the water collection channel 62, and to prevent fallen leaves and other garbage from entering the water collection channel 62.

[0048] Example 3:

[0049] The stormwater collection and recycling vehicle described in Example 2 is used for cleaning the stormwater collection channels of an urban stormwater harvesting and recycling system. This system includes a four-level source stormwater collection channel 68, a three-level main road stormwater collection channel 69, a two-level regional stormwater collection channel 70, a first-level urban water supply pipeline 71, a drainage pipe 72, a filtration and sedimentation tank 73, an upstream dam 74, a reuse pipeline 75, a coarse screen 77, a downstream dam 78, a pumping device 79, a suburban reservoir 80, and a solar power system. The four-level source stormwater collection channel 68 is located on secondary urban roads... Along both sides of secondary roads and street blocks, rainwater covers 65 are installed on the upper side of the fourth-level source drainage channel 68. These covers prevent rainwater debris such as dead branches, fallen leaves, and garbage from entering the drainage channel. A filter layer is installed on one side of the green belt above the fourth-level source drainage channel 68 to intercept blockages such as dead branches, fallen leaves, gravel, and coarse sand. The outlet of the fourth-level source drainage channel 68 connects to the third-level main road drainage channel 69. A stainless steel grating is installed at the outlet of the fourth-level source drainage channel 68 to intercept blockages such as dead branches, fallen leaves, gravel, and garbage within the channel. The connection point between the fourth-level source drainage channel 68 and the third-level main road drainage channel 69 is located at the intersection of the urban secondary arterial road, branch road, street road, and urban main road. The third-level main road drainage channel 69 is located on both sides of the urban main road, with rainwater covers 65 installed on its upper side. A filter layer is installed on one side of the green belt above the third-level main road drainage channel 69. The third-level main road drainage channel 69 passes through the urban secondary arterial road, branch road, and street road. A stainless steel grating is installed at the outlet of the third-level main road drainage channel 69 to intercept dead branches. Blockages caused by fallen leaves, gravel, coarse sand, etc., are prevented. The outlet of the tertiary main road drainage channel 69 within the same area is connected to the secondary regional drainage channel 70 of the same area. Depending on the size of the area, one or more secondary regional drainage channels 70 are set up within the area. The secondary regional drainage channels 70 are set up on the ground surface on both sides of the main road within the area, and rainwater covers 65 are installed on the upper side of the secondary regional drainage channels 70. Alternatively, the secondary regional drainage channels 70 can be set up directly underground on both sides of the main road, and the outlet of the secondary regional drainage channels 70 is connected to the urban river or the primary urban water supply pipeline 71.When the outlet of the secondary area water collection channel 70 is connected to the primary urban water transmission pipeline 71, the primary urban water transmission pipeline 71 is installed underground in the city or utilizes the existing urban underground pipe network. A filtration and sedimentation tank 73 is installed at the outlet of the primary urban water transmission pipeline 71. The filtration and sedimentation tank 73 is divided into two parts by a coarse screen 77 with a bar spacing of 25-45mm. Rainwater collected by the secondary area water collection channel 70 enters the first half of the filtration and sedimentation tank 73. The screen in the filtration and sedimentation tank 73 intercepts larger blockages such as dead branches, fallen leaves, gravel, coarse sand, and garbage in the secondary area water collection channel 70. The second half of the filtration and sedimentation tank 73 is used for sedimentation of silt. A drainage outlet is opened in the second half of the filtration and sedimentation tank 73, and a fine screen is installed at the drainage outlet. The bar spacing of the grating is 10-20mm. The fine grating is used to intercept suspended matter such as leaves and grass clippings. The drainage outlet of the filter sedimentation tank 73 is connected to the drainage pipe 72. Rainwater from the primary urban water supply pipeline 71 flows into the suburban reservoir 80 through the filter sedimentation tank 73 and the drainage pipe 72. When the outlet of the secondary regional water collection channel 70 connects to the urban river, a filter sedimentation tank 73 is installed at the outlet of the secondary regional water collection channel 70. The filter sedimentation tank 73 installed at the outlet of the secondary regional water collection channel 70 is connected to the urban river through the drainage pipe 72. The urban river is connected to the suburban reservoir 80. A downstream dam 78 is installed in the urban river to control whether the water in the urban river is discharged into the suburban reservoir 80. The suburban reservoir 80 is a natural lake or artificial lake. Reservoirs, such as the suburban reservoir 80, are located in lower-lying areas downstream of urban rivers. These suburban reservoirs also function as wetland parks, planting aquatic plants such as reeds and cattails to further purify the water. Each suburban reservoir 80 is equipped with a pumping device 79, which uses submersible pumps or axial flow pumps. The pumping device 79 is connected to a return pipeline 75, which is a pressure pipeline laid along the riverbank or riverbed, transporting water upstream from the downstream intake point to the upstream section of the urban river. An upstream dam 74 is installed on the return pipeline 75, featuring fountains or cascading aeration tanks to increase dissolved oxygen and enhance the landscape. Multiple water intake stations are established along the return pipeline 75 within the urban area, drawing water for road watering and dust suppression, as well as for urban greening irrigation. A solar power supply system is installed in the urban waterways. The solar power supply system includes solar panels 76 and an energy storage and distribution device. The solar panels 76 are installed on the upper side of the urban waterways and are arranged along the waterways. The solar panels 76 are used to generate electricity and reduce the evaporation of river water in summer. The solar panels 76 are connected to the energy storage and distribution device, which supplies power to the riverside landscape lights and the pumping device 79. When the solar energy storage is sufficient, it directly supplies power using solar energy. When the solar energy storage is insufficient or there are continuous cloudy or rainy days, it automatically switches to the mains power to ensure uninterrupted operation of the system. Water collection wells are set in front of the drainage outlets of the four-level source water collection channel 68, the three-level main road water collection channel 69, and the two-level regional water collection channel 70. The water collection wells are used to settle silt and other blockages to prevent the drainage outlets from being blocked.The bottom slope of the fourth-level source drainage channel 68, the third-level main road drainage channel 69, and the second-level surface area drainage channel 70 is the same as the road slope.

[0050] The method for collecting and utilizing rainwater using an urban rainwater harvesting and recycling system is as follows:

[0051] (1) Branch water collection: In the urban area, a four-level source water collection channel 68, a three-level main road water collection channel 69, a two-level regional water collection channel 70, a filtration and sedimentation tank 73, and a first-level urban water transmission pipeline 71 are set up to construct an urban rainwater collection and recycling system; rainwater from urban secondary roads, branch roads, and street roads flows into the four-level source water collection channel 68;

[0052] (2) Third-level main road water collection: rainwater from the city's main roads and the fourth-level source water collection channel 68 flows into the third-level main road water collection channel 69;

[0053] (3) Secondary regional water collection: Select two or more urban main roads as urban regional main roads, and set up secondary regional water collection channels 70 along the urban regional main roads. The rainwater from the urban main roads and the tertiary main road water collection channels 69 flows into the secondary regional water collection channels 70.

[0054] (4) Secondary area water collection, filtration and sedimentation: A filtration and sedimentation tank 73 is set at the outlet of the secondary area water collection channel 70. The rainwater collected by the secondary area water collection channel 70 enters the filtration and sedimentation tank 73 for filtration and sedimentation. The filtration and sedimentation tank 73 is cleaned regularly and after rain.

[0055] (5) Primary urban water collection: Rainwater from secondary regional water collection channel 70 flows into urban rivers or primary urban water transmission pipeline 71, and rainwater from urban rivers or primary urban water transmission pipeline 71 flows into suburban reservoir 80.

[0056] (6) Water collection and reuse: Using pumping device 79 and return pipeline 75, the stored water of suburban reservoir 80 is transported upstream from the downstream water intake point to the upstream of the urban river. During the dry season, the urban river is replenished with water. Multiple water intake stations are set up in sections of the return pipeline 75 in the urban area. Water is taken from the water intake stations and used for road watering and dust suppression as well as urban greening irrigation.

[0057] (7) Green energy supply: The urban river is equipped with a solar power supply system, which supplies power to the riverside landscape lights and water pumping devices.

[0058] (8) Water collection channel cleaning: Use a water collection channel cleaning vehicle to periodically clean the surface water collection channels to ensure smooth drainage.

[0059] The method for collecting and utilizing rainwater using an urban rainwater harvesting and recycling system is as follows:

[0060] (1) Branch water collection: A four-level source water collection channel 68, a three-level main road water collection channel 69, a two-level regional water collection channel 70, a filter sedimentation tank 73, and a first-level urban water transmission pipeline 71 are set up in the urban area to construct an urban rainwater collection and recycling system. The bottom slope of the four-level source water collection channel 68, the three-level main road water collection channel 69, and the two-level regional water collection channel 70 on the ground surface is the same as the road slope. The four-level source water collection channel 68 is set up on both sides of the secondary arterial roads, branch roads, and street roads in the city. The four-level source water collection channel 68 is equipped with a flip-type rainwater cover 65. A filter layer is set up on one side of the green belt above the four-level source water collection channel 68. When it rains, the rainwater collected by the green belt is filtered through the filter layer and flows into the four-level source water collection channel 68 through the rainwater cover 65. The rainwater from the secondary arterial roads, branch roads, and street roads in the city flows directly into the four-level source water collection channel 68 through the rainwater cover 65.

[0061] (2) Three-level main road water collection: Three-level main road water collection channels 69 are set on both sides of the main road of the city. The three-level main road water collection channels 69 are equipped with flip-type rainwater covers 65. A filter layer is set on one side of the green belt above the three-level main road water collection channels 69. The four-level source water collection channel 68 is connected to the three-level main road water collection channel 69. The elevation of the bottom surface of the three-level main road water collection channel 69 is lower than that of the bottom surface of the four-level source water collection channel 68. When it rains, the rainwater collected by the green belt is filtered through the filter layer and flows into the three-level main road water collection channel 69 through the rainwater cover 65. The rainwater of the main road of the city flows directly into the three-level main road water collection channel 69 through the rainwater cover 65. A stainless steel grating is set at the outlet of the four-level source water collection channel 68. The rainwater collected by the four-level source water collection channel 68 is filtered by the stainless steel grating to remove leaves, garbage and other blockages and flows into the three-level main road water collection channel 69.

[0062] (3) Secondary regional water collection: The city is divided into two or more regions, and two or more urban arterial roads are selected as urban regional arterial roads. The urban regional arterial roads should meet the conditions of being low-lying within the region and having many intersections with other urban arterial roads within the region (e.g., the urban regional arterial road intersects with other urban arterial roads within the region more than 5 times); the outlet of the tertiary arterial road water collection channel 69 is equipped with a stainless steel grating. During rainfall, the rainwater collected by the tertiary arterial road water collection channel 69 flows into the secondary regional water collection channel 70 after being filtered by the stainless steel grating to remove leaves, garbage and other blockages; the secondary regional water collection channel 70 is set on the surface of both sides of the main road within the region or on both sides of the underground main road. The bottom end of the secondary regional water collection channel 70 faces the sea. The elevation is lower than the bottom surface elevation of the secondary main road drainage channel 69; when the secondary regional drainage channel 70 is located on the ground surface on both sides of the urban main road, a rainwater cover 65 is installed on the upper part of the secondary regional drainage channel 70, and a filter layer is installed on one side of the green belt above the secondary regional drainage channel 70. Rainwater collected by the tertiary main road drainage channel 69 flows into the secondary regional drainage channel 70, and rainwater collected by the green belt flows into the secondary regional drainage channel 70 through the rainwater cover 65 after being filtered by the filter layer. Rainwater from the main road flows directly into the secondary regional drainage channel 70 through the flip-type rainwater cover 65; when the secondary regional drainage channel 70 is located underground on both sides of the main road, rainwater collected by the tertiary main road drainage channel 69 flows into the secondary regional drainage channel 70.

[0063] (4) Secondary area water collection, filtration and sedimentation: A filtration and sedimentation tank 73 is set at the outlet of the secondary area water collection channel 70. The filtration and sedimentation tank 73 is divided into two parts by a coarse screen 77. The spacing between the bars of the coarse screen 77 is 25-45mm, which intercepts large-volume garbage such as tree branches and plastic bags. The rainwater collected by the secondary area water collection channel 70 enters the front half of the filtration and sedimentation tank 73. The screen of the filtration and sedimentation tank 73 intercepts the blockages such as dead branches, fallen leaves, gravel, coarse sand, and garbage in the secondary area water collection channel 70. A drain outlet is opened in the rear half of the filtration and sedimentation tank 73. A fine screen is installed at the drain outlet. The spacing between the bars of the fine screen is 10-20mm. The fine screen is used to intercept suspended matter such as leaves and grass clippings. The rainwater collected by the secondary area water collection channel 70 enters the filtration and sedimentation tank 73 for filtration and sedimentation. The filtration and sedimentation tank 73 is periodically cleaned and cleaned after rain.

[0064] (5) Primary urban water collection: The secondary regional water collection channel 70 is connected to the urban river through the filtration and sedimentation tank 73, or the outlet of the secondary regional water collection channel 70 is connected to the primary urban water transmission pipeline 71. The primary urban water transmission pipeline 71 is set underground in the city or utilizes the existing urban underground pipe network. The rainwater from the urban river or the primary urban water transmission pipeline 71 flows into the suburban reservoir 80. The rainwater from the primary urban water transmission pipeline 71 or after being filtered by the filtration and sedimentation tank 73 flows into the suburban reservoir 80. The suburban reservoir 80 is set in a lower-lying area downstream of the city.

[0065] (6) Water collection and reuse: A pumping device 79 is installed in the suburban reservoir 80. The pumping device 79 is connected to the return pipeline 75. The return pipeline 75 is installed along the river. The pumping device 79 transports the water in the reservoir from the downstream water intake point to the upstream of the river in the city. A fountain or waterfall aeration pool is set up in the upstream of the river to replenish the river in the city during the dry season. In the city, multiple water intake stations are set up in sections of the return pipeline 75. Water is taken from the water intake stations and used for road watering and dust suppression as well as urban greening irrigation.

[0066] (7) Green energy supply: The urban river is equipped with a solar power supply system. The solar panels 76 of the solar power supply system are installed on the upper side of the urban river. The solar panels 76 are arranged along the river. The solar panels 76 are used to generate electricity and reduce the evaporation of river water in summer. The solar panels 76 are connected to the energy storage and distribution device. The energy storage and distribution device supplies power to the riverside landscape lights and the pumping device 79. When the solar energy storage is sufficient, the solar energy is used to directly supply power. When the solar energy storage is insufficient or there are continuous cloudy and rainy days, the system will automatically switch to the mains power to ensure uninterrupted operation.

[0067] (8) Drainage channel cleaning: The surface drainage channel 62 is cleaned regularly using a drainage channel cleaning vehicle to ensure smooth drainage; the specific cleaning steps are as follows:

[0068] Step 1: Cleaning the end of the water collection channel: During cleaning, first open three or more rainwater covers 65 at the end of the water collection channel 62. The rainwater covers 65 are opened vertically by rotating through the cover shaft 67. Manually clean the debris in the water collection channel 62 at the location of the opened rainwater covers 65. After cleaning the debris, move the water collection channel cleaning vehicle. Using the monitoring camera installed on the tilting part 4 of the water collection channel cleaning vehicle, ensure that the tilting head 45 is positioned above the opened rainwater covers 65.

[0069] Step 2: The cleaning unit is lowered into the water collection channel: The water collection channel cleaning vehicle lowers the cleaning unit, and the descent of the cleaning unit is controlled by the monitoring camera installed on the tilting part 4 of the water collection channel cleaning vehicle; when the front of the tilting head 45 falls to the water collection channel 62, the descent of the cleaning unit stops. At this time, the upper end of the front end of the tilting head 45 is lower than the lower end of the horizontally closed rainwater cover 65, and the lower end of the tilting head 60 is close to the upper end of the water collection channel 62. The upright rainwater cover 65 is located inside the tilting part 4.

[0070] Step 3: Lower the excavator to the water collection channel: Activate the hydraulic telescopic device 5, and the telescopic excavator 3 tilts and extends downward. The hydraulic telescopic device 5 is equipped with a force feedback system (the force feedback system uses an existing hydraulic pressure sensor or load sensor). When the telescopic excavator 3 descends to the bottom of the water collection channel 62, it stops descending and automatically rises 2-3 cm. The water collection channel cleaning vehicle moves forward and flips up the front end of the lifting head 45 to the lower end of the unopened rainwater cover 65.

[0071] Step 4: Flipping and resetting of rainwater cover 65: As the water collection channel cleaning vehicle moves forward, the closed rainwater cover 65 rotates sequentially from a horizontal to a vertical state along the inclined surface of the flipping head 45 with the cover shaft 67 as the pivot. Then, the water collection channel cleaning vehicle continues to move forward, and the raised rainwater cover 65 enters the vertical holding narrow channel of the flipping part. Finally, the raised rainwater cover 65 rotates from the vertical holding narrow channel of the flipping part to the flipping return head 60. The raised rainwater cover 65 rotates sequentially from the vertical state to the horizontal state along the inclined surface of the flipping return head 60 with the cover shaft 67 as the pivot. The rear end of the inner side wall of the flipping outer side plate 59 of the flipping part is provided with an inclined protrusion 81. The inclined protrusion 81 is an arc-shaped gentle slope that protrudes inward and outward. The inclined protrusion 81 assists the raised rainwater cover 65 in changing from the vertical state to the horizontal state.

[0072] Step 5: Waterway garbage cleaning and transportation: As the closed rainwater cover 65 is raised as the waterway cleaning vehicle moves forward, the front plow head of the telescopic breaking plow 3 breaks open the silt, fallen leaves, garbage and other sediments deposited in the waterway 62. The sediments are pushed upward along the telescopic breaking plow 3 through the plow plate box 23 into the inclined conveyor belt 17. The inclined conveyor belt 17 transports the sediments upward to the transverse conveyor belt 15. The sediments are then transported to the carriage 1 via the transverse conveyor belt 15.

[0073] Step 6: Waterway Cleaning and Turning: When the waterway cleaning vehicle moves to the end of a waterway 62, the hydraulic telescopic device 5 controls the telescopic breaking plow 3 to tilt upward and retract. The lifting device 2 of the waterway cleaning vehicle raises the telescopic breaking plow 3 to the upper end face of the waterway 62 (the lower end face of the telescopic breaking plow of the cleaning part is 2-3 cm higher than the upper end face of the waterway). The waterway cleaning vehicle continues to move straight, so that all the rainwater covers 65 located in the turning part 4 are finally reset to the horizontal closed state after the "horizontal-vertical-horizontal" change process. After the waterway cleaning vehicle turns, the remaining waterways 62 are cleaned according to steps 1-6 until all surface waterways 62 are cleaned. The garbage in the truck compartment 1 is transferred to the garbage disposal site.
