Description

Technical Field

[0001] This invention relates to the field of rainwater and sewage separation technology, specifically to a smart road rainwater and sewage separation system for sponge cities. Background Technology

[0002] Sponge city is a new generation of urban stormwater management concept. It refers to the ability of a city to absorb, store, infiltrate, and purify rainwater when it rains, and release and utilize the stored water when needed, so as to realize the free migration of rainwater in the city. Rainwater and sewage separation, as a drainage system, refers to the separation of rainwater and sewage, which are transported by separate pipelines for discharge or subsequent treatment. It is also a fundamental solution to improve urban infrastructure, solve urban flooding and waterlogging, and eliminate black and odorous water bodies.

[0003] Existing technologies for rainwater and sewage separation in sponge cities involve designing two types of pipes: sewage pipes and rainwater pipes. One end of the sewage pipe is connected to an industrial or household drainage pipe, while the other end of the rainwater pipe is installed at the road sewer. Connecting the sewage and rainwater pipes together achieves rainwater and sewage separation, thereby improving water transport efficiency. However, urban road drainage systems typically only have sewers for rapid rainwater treatment to prevent urban flooding. This method, because it does not involve sewage pipes and only treats rainwater discharge, is economical to implement and can meet the needs of most main roads in cities.

[0004] However, this approach is not suitable for all roads. For example, roads with a large number of street vendors promoted by the government, night markets, and roadside restaurants are often used as sewage pipes. However, these roads were not designed with sewage treatment in mind. This sewage often contains a lot of grease and condiments, and rainwater treatment generally does not have steps to treat grease and condiments. As a result, the discharge of this sewage will affect the ecological environment of rivers and easily cause urban flooding during rain, affecting the lives of surrounding residents and traffic.

[0005] In view of the above, in order to overcome the above technical problems, the present invention designs a smart road rainwater and sewage separation system for sponge cities, which solves the above technical problems. Summary of the Invention

[0006] The technical objective of this invention is to provide a method for separating rainwater and sewage for roads near residential areas, especially those with domestic sewage discharge, to improve road pipe blockage and increase rainwater discharge efficiency with minimal changes to existing paving.

[0007] To achieve the above-mentioned technical objectives, the present invention provides the following technical solution:

[0008] This invention provides a smart road stormwater and sewage separation system for sponge cities, comprising a protective cover, a protective shell, a stormwater and sewage co-flow pipe, a connecting pipe, a rainwater direct flow pipe, a sewage discharge pipe, and a rainwater discharge pipe. The protective cover is installed on top of the protective shell, which strengthens the overall structural integrity and prevents upper-layer pressure from affecting the protective shell. The stormwater and sewage co-flow pipe and the rainwater direct flow pipe are installed on the side of the protective shell. The stormwater and sewage co-flow pipe is responsible for all water discharge during periods of no rain or low rainfall. The rainwater direct flow pipe is responsible for transporting rainwater from the stormwater and sewage co-flow pipe into the interior of the protective shell during periods of heavy rainfall. The connecting pipe is installed on... Between the two, the connecting pipe is used when there is heavy rainfall, rainwater will fill the combined rainwater and sewage pipe, and a portion of it will enter the rainwater direct pipe through the connecting pipe. The sewage discharge pipe is installed below the protective shell, and the rainwater discharge pipe is installed on the other side of the protective shell. It also includes a diversion mechanism and an adjustment mechanism. The diversion mechanism is installed inside the protective shell, and the adjustment mechanism is installed in the middle of the diversion mechanism. The high flow of sewage mixed with the rainwater enters the rainwater cavity through the connecting pipe and the rainwater direct pipe. Under the influence of the rising water level, the float drives the rotating gear to rotate at a certain angle, so that the rotating rod drives the control cover to cover the through hole.

[0009] The regulating mechanism includes a fixed housing, a float, a connecting pipe, a rotating assembly, a control cover, and an adjusting slider. The fixed housing is mounted on the side of the diversion mechanism, the float is mounted below the fixed housing, and the connecting pipe is mounted in the middle of the diversion mechanism. The connecting pipe connects the rainwater chamber, the transition chamber, and the collecting chamber, allowing rainwater to flow out through the rainwater drain pipe and initially intercepting and filtering solids in the water. Two connecting pipes are provided, and interception strips are installed in a circular array on the side of the connecting pipes. The interception strips are used to intercept and filter solids and guide the water flow through the connecting pipes.

[0010] The vertical cross-sectional shape of the interception bar is trapezoidal. The trapezoidal design can improve the interception efficiency. The interception bar is tapered away from the connecting pipe to ensure water flow efficiency and avoid urban flooding. The rotating component is installed on the side of the fixed housing. The control cover is installed at one end of the rotating component. The adjusting slider is installed on the top of the control cover. The adjusting slider is used to divert and discharge the water flow in the transition cavity under the action of the control cover, reducing the direct impact of the water flow on the control cover and improving the structural stability of the control cover.

[0011] The fixed housing includes a fixed bracket, a circular shell, a rotating gear, a rectangular shell, and a vertical slide groove. The fixed bracket is installed on the side of the diversion mechanism, the circular shell is installed on the fixed bracket, and the fixed bracket is symmetrically arranged about the central axis of the circular shell to balance the torque on both sides and improve the installation stability. The rotating gear is installed inside the circular shell and drives the rotating component to rotate. The rectangular shell is installed on the side of the circular shell, and a vertical slide groove is opened on the inner side of the rectangular shell away from the circular shell.

[0012] A rectangular connecting block is installed above the float, and a rack is installed on the top of the connecting block. The rack can drive the gear to rotate, causing the rotating component connected to its other end to rotate at a certain angle, thereby realizing the control of the cover plate. A vertical slider is installed on the side of the rack. The horizontal cross-sectional shape of the vertical slider is trapezoidal, and the trapezoidal vertical slider has a better limiting effect.

[0013] The rotating assembly includes a rotating rod, a positioning block, a limiting block, and a fixing block. One end of the rotating rod is mounted on the side of the fixed housing. The rotating rod is L-shaped, which can convert vertical rotation into a swing motion at a certain angle. The positioning block is mounted on the other end of the rotating rod. The limiting block is mounted on both sides of the positioning block and is used to limit the range of motion of the control cover. The fixing block is mounted between the positioning block and the limiting block. The fixing block has a star-shaped cross-section, which can effectively fix the tilt of the control cover.

[0014] The control cover includes a connecting protrusion, a fixing groove, a sealing ring, and a pressure balancing notch. The connecting protrusion is installed on the top of the control cover, and the fixing groove is located on the side of the connecting protrusion, securing the control cover. The sealing ring is installed on the bottom of the control cover, enhancing its sealing performance to prevent water leakage. The pressure balancing notch is located on the bottom of the control cover. When the control cover is opened, negative pressure can make it difficult to open; the pressure balancing notch balances the pressure on both sides, ensuring the normal operation of the control cover. The pressure balancing notch is located on the center line of the two connecting protrusions and is V-shaped. The V-shaped pressure balancing notch quickly balances the internal and external pressures, and its larger opening faces outwards, facilitating gas flow.

[0015] The adjusting slider has a mounting boss on its side, and a ball rod is mounted on the side of the mounting boss. The ball rod is used for multi-angle movement to drive the mounting boss to move. The other end of the ball rod is equipped with a mounting block. The mounting block causes the adjusting slider to move under the action of the control cover plate. The bottom of the adjusting slider is set as an arc surface, and the arc surface matches the shape of the fixing ring.

[0016] The diversion mechanism includes a partition plate, a transition cavity, a rainwater cavity, a collecting cavity, a fixing ring, a through hole, and a mounting hole. The partition plate is installed inside the protective shell and is used to divide the internal cavities of the protective shell, thereby designing different cavities to cope with different situations and improve work efficiency. The partition plate is designed with a "T" shape, which facilitates the detailed division of rainwater and sewage diversion, ensuring the treatment of sewage during normal times and rapid discharge during rainfall. The transition cavity is the area where rainwater and sewage flow through the same pipe. The transition cavity is mainly the area through which sewage passes when rainfall is low or there is no rainfall. A sewage discharge pipe is connected to the bottom of the transition cavity, and this part of the sewage will flow into the sewage treatment plant for treatment.

[0017] The rainwater chamber is the area connected to the direct rainwater pipe. The rainwater chamber primarily treats rainwater during rainfall, which is then transported through a connecting pipe into the rainwater drainage pipe for treatment before being discharged. The collecting chamber is the area composed of a partition plate and an outer shell. The collecting chamber discharges rainwater into the rainwater drainage pipe. In the event of damage to the connecting pipe or control cover, drainage can also be achieved through the connecting pipe installed in the transition chamber and the collecting chamber. It should be noted that the connecting pipe here should be placed at a high position to avoid interfering with the normal operation of the transition chamber. The fixing ring is installed at the inlet of the combined rainwater and sewage pipe. The through hole is opened on the partition plate below the transition chamber, and then discharged through the sewage drainage pipe. The mounting hole is opened on the partition plate.

[0018] The lower part of the fixed ring is equipped with a fixed plate. The vertical cross-sectional shape of the fixed plate is a fan-shaped ring. The outer diameter of the fan-shaped fixed ring is the same as the radius of the arc surface. Thus, during the sliding of the fixed block, the water flow of the fixed ring can be adjusted, so that it is diverted to both sides under the interception of the fixed block, thereby reducing the direct impact of the water flow on the control cover plate.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention separates daily sewage discharge and rainwater discharge by setting up an adjustment mechanism and a diversion mechanism, which not only ensures the efficiency of sewage treatment, but also improves the drainage efficiency during rainfall, enhances the water absorption of sponge cities, and avoids urban flooding.

[0021] 2. This invention, by setting an adjustment mechanism, intelligently adjusts the opening and closing of the through hole according to the rainfall, thereby achieving rainwater and sewage separation. In the case of heavy rainfall, it adopts dual-channel drainage to improve drainage efficiency and ensure the drainage capacity of the sponge city.

[0022] 3. By setting up a connecting pipe, the present invention intercepts solid debris in rainwater and sewage, effectively reducing the risk of pipe blockage and improving the stability of pipe flow; and by setting up an adjusting slider, the water flow is split into two sides to avoid direct impact contact between the water flow and the tilted control cover.

[0038] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0039] like Figures 1 to 12 As shown, a smart road stormwater and sewage separation system for sponge cities includes a protective cover 1, a protective shell 2, a stormwater and sewage co-flow pipe 3, a connecting pipe 4, a rainwater direct flow pipe 5, a sewage discharge pipe 6, and a rainwater discharge pipe 7. The protective cover 1 is installed above the protective shell 2, which is used to strengthen the overall structural strength and prevent upper pressure from affecting the protective shell 2. The stormwater and sewage co-flow pipe 3 and the rainwater direct flow pipe 5 are installed on the sides of the protective shell 2. The stormwater and sewage co-flow pipe is responsible for all water discharge when there is no rain or low rainfall. The rainwater direct flow pipe 5 is responsible for transporting rainwater from the stormwater and sewage co-flow pipe 3 into the interior of the protective shell 2 during heavy rainfall. The connecting pipe 4 is installed between the two. Channel 4 is used when there is heavy rainfall. Rainwater will fill the rainwater and sewage combined pipe 3, and a part of it will enter the rainwater direct pipe 5 through the connecting bridge pipe 4. The sewage discharge pipe 6 is installed below the protective shell 2, and the rainwater discharge pipe 7 is installed on the other side of the protective shell 2. It also includes a diversion mechanism 8 and an adjustment mechanism 9. The diversion mechanism 8 is installed inside the protective shell 2, and the adjustment mechanism 9 is installed in the middle of the diversion mechanism 8. The high flow of sewage mixed flows into the rainwater cavity 83 through the connecting bridge pipe 4 and the rainwater direct pipe 5. Under the influence of the rising water level, the float ball 92 drives the rotating gear 913 to rotate at a certain angle, so that the rotating rod 941 drives the control cover plate 95 to cover the through hole 86.

[0040] During the initial road construction, the stormwater and sewage combined pipe 3 was connected to the urban road sewer system. The sewage discharge pipe 6 led to the sewage treatment plant, and the stormwater direct pipe 5 led to the stormwater treatment station and discharged. The protective shell 2 was installed underground, and then the protective cover 1 was installed on the protective shell 2.

[0041] like Figure 2 As shown, the adjustment mechanism 9 includes a fixed housing 91, a float 92, a connecting pipe 93, a rotating assembly 94, a control cover 95, and an adjusting slider 96. The fixed housing 91 is installed on the side of the diversion mechanism 8 and is used to drive the rotating assembly 94 to rotate. The float 92 is installed below the fixed housing 91 and is used to detect the water level inside the rainwater chamber 83. As the water level inside the rainwater chamber 83 rises, the float moves upward under the action of buoyancy, driving the rotating assembly 94 to rotate. The connecting pipe 93 is installed in the middle of the diversion mechanism 8 and is used to connect the rainwater chamber 83, the transition chamber 82, and the collecting chamber 84, so that rainwater can flow out through the rainwater drain pipe 7 and perform preliminary interception and filtration of solids in the water. Two connecting pipes 93 are provided, and interception bars 931 are installed in a circular array on the side of the connecting pipes 93. 31 is used to intercept and filter solids and guide water flow through the connecting pipe 93. The vertical cross-sectional shape of the intercepting bar 931 is trapezoidal. The trapezoidal design can improve the interception efficiency. The intercepting bar 931 is tapered away from the connecting pipe 93 to ensure water flow efficiency and avoid urban flooding. The rotating component 94 is installed on the side of the fixed housing 91. The rotating component 94 is used to rotate and drive the control cover plate 95 to rotate a certain angle. The control cover plate 95 is installed at one end of the rotating component 94. The control cover plate 95 is used to adjust the fixed ring 85 set inside the transition cavity 82. The adjusting slider 96 is installed on the top of the control cover plate 95. The adjusting slider 96 is used to divert and discharge the water flow in the transition cavity 82 under the drive of the control cover plate 95, reduce the direct impact of the water flow on the control cover plate 95, and improve the structural stability of the control cover plate 95.

[0042] Rainwater first enters the transition chamber through the combined rainwater and sewage pipe 3. Excess rainwater enters the rainwater direct pipe 5 through the connecting bridge pipe 4, and then enters the rainwater chamber 83. The water level in the rainwater chamber 83 continues to rise. Under the buoyancy of the rainwater chamber 83, the float 92 drives the rack 922 to move upward. The rotating gear 913 rotates under the meshing of the rack 922, driving the rotating rod 941 to rotate at a certain angle. The control cover 95 fixed at one end of the rotating rod 941 moves downward, thus fitting against the through hole 86 and closing the through hole 86. Rainwater can then be diverted from the connecting pipe 93 in the transition chamber into the collecting chamber 84, realizing rapid drainage through the dual pipes in the case of heavy rainfall. The rainwater in the collecting chamber 84 is discharged through the rainwater drain pipe 7.

[0043] like Figure 3 and Figure 4 As shown, the fixed housing 91 includes a fixed bracket 911, a circular shell 912, a rotating gear 913, a rectangular shell 914, and a vertical slide groove 915. The fixed bracket 911 is installed on the side of the diversion mechanism 8 and is used to fix the fixed housing 91. The circular shell 912 is installed on the fixed bracket 911 and is used to install the rotating gear 913. The fixed bracket 911 is symmetrically arranged about the central axis of the circular shell 912 to balance the torque on both sides and improve the installation stability. The rotating gear 913 is installed inside the circular shell 912 and is used to rotate under the drive of the rack 922, thereby driving the rotating assembly 94 to rotate. The rectangular shell 914 is installed on the side of the circular shell 912 and is used to facilitate the movement of the rack 922. A vertical slide groove 915 is provided on the inner side of the rectangular shell 914 away from the circular shell 912. The vertical slide groove 915 provides a limiting function during the sliding of the rack 922.

[0044] like Figure 3 As shown, a rectangular connecting block 921 is installed above the float 92. The connecting block 921 is used to install a rack 922 above the float 92. The rack 922 is installed on top of the connecting block 921. When the float 92 is buoyed by the rising water level in the rainwater chamber, the rack 922 can drive the gear to rotate, causing the rotating component 94 connected to its other end to rotate by a certain angle, thereby controlling the control cover 95. A vertical slider 923 is installed on the side of the rack 922. The vertical slider 923 is used to keep the rack 922 vertical during its upward movement. The horizontal cross-sectional shape of the vertical slider 923 is trapezoidal. The trapezoidal vertical slider 923 has a better limiting effect.

[0045] like Figure 5 As shown, the rotating assembly 94 includes a rotating rod 941, a positioning block 942, a limiting block 943, and a fixing block 944. One end of the rotating rod 941 is installed on the side of the fixed housing 91. The rotating rod 941 is L-shaped, which can convert vertical rotation into a swing motion at a certain angle. The positioning block 942 is installed at the other end of the rotating rod 941 and is used to assist in limiting the two sides of the control cover 95. The limiting block 943 is installed on both sides of the positioning block 942 and is used to limit the range of motion of the control cover 95. The fixing block 944 is installed between the positioning block 942 and the limiting block 943. The cross-sectional shape of the fixing block 944 is star-shaped, which can provide good fixation for the tilting of the control cover 95.

[0046] like Figure 6 As shown, the control cover 95 includes a connecting protrusion 951, a fixing groove 952, a sealing ring 953, and a pressure balancing notch 954. The connecting protrusion 951 is installed on the top of the control cover 95 and is used to fix the control cover 95 to the rotating rod 941. The fixing groove 952 is opened on the side of the connecting protrusion 951 and is used to cooperate with the fixing block 944 to fix the control cover 95. The sealing ring 953 is installed on the bottom of the control cover 95 and is used to improve the sealing performance of the control cover 95, thereby preventing water from overflowing. The pressure balancing notch 954 is opened on the bottom of the control cover 95. When the control cover 95 is opened, it may be difficult to open due to negative pressure. The pressure balancing notch 954 can balance the air pressure on both sides to ensure the normal operation of the control cover 95. The pressure balance gap 954 is located on the center line of the two connecting protrusions 951, and the pressure balance gap 954 is set in a "V" shape. The "V" shaped pressure balance gap 954 can quickly balance the internal and external pressure. The larger opening of the "V" shaped pressure balance gap 954 is set outward, which facilitates gas flow.

[0047] When there is little or no rainfall, the control cover 95 maintains a distance from the through hole 86. Sewage enters the transition chamber from the rainwater and sewage co-flow pipe 3 and is intercepted and diverted by the regulating plate 964 to reduce the impact on the control cover 95. When there is a lot of rainfall, the control cover 95 covers the through hole 86 and blocks the through hole 86 so that the incoming rainwater can only enter the collection chamber 84 through the connecting pipe 93.

[0048] like Figure 7 , Figure 8 and Figure 9 As shown, a mounting boss 963 is installed on the side of the adjusting slider 96. The mounting boss is used to connect the ball rod 962 and the adjusting slider 96. The ball rod 962 is installed on the side of the mounting boss. The ball rod 962 is used for multi-angle movement to drive the mounting boss to move. A mounting block 961 is installed at the other end of the ball rod 962. The mounting block 961 is used to connect with the control cover plate 95, so that the adjusting slider 96 can move under the drive of the control cover plate 95. The bottom of the adjusting slider 96 is set as an arc surface, and the arc surface matches the shape of the fixing ring 85.

[0049] like Figure 10 and Figure 11As shown, the diversion mechanism 8 includes a partition plate 81, a transition cavity 82, a rainwater cavity 83, a collecting cavity 84, a fixing ring 85, a through hole 86, and a mounting hole 87. The partition plate 81 is installed inside the protective shell 2 and is used to divide the cavities inside the protective shell 2, thereby designing different cavities to cope with different situations and improve work efficiency. The partition plate 81 is set as a "T" shape, which is conducive to the detailed division of rainwater and sewage diversion, and provides a guarantee for the treatment of sewage on a daily basis and rapid discharge during rainfall. The transition cavity 82 is the area where rainwater and sewage are connected to the same flow pipe 3. The transition cavity 82 is mainly the area where sewage passes through when there is little rainfall or no rainfall. The sewage discharge pipe 6 is connected to the bottom of the transition cavity 82, and this part of the sewage will flow into the sewage treatment plant for treatment.

[0050] like Figure 10 As shown, the rainwater cavity 83 is the area connected to the rainwater direct pipe 5. The rainwater cavity 83 mainly treats rainwater during rainfall, which is then transported to the rainwater drainage pipe 7 through the connecting pipe 93 and discharged after treatment. The collecting cavity 84 is the area composed of the partition plate 81 and the outer shell. The collecting cavity 84 discharges rainwater into the rainwater drainage pipe 7. In the event of damage to the connecting pipe 4 or the control cover plate 95, drainage can also be carried out through the connecting pipe 93 installed in the transition cavity 82 and the collecting cavity 84. It should be noted that the connecting pipe 93 should be placed in a high position to avoid interfering with the normal operation of the transition cavity. The fixing ring 85 is installed at the pipe opening of the rainwater and sewage combined pipe 3. The through hole 86 is opened on the partition plate 81 below the transition cavity 82. The through hole 86 is used to discharge sewage downwards and then discharge it through the sewage drainage pipe 6. The mounting hole 87 is opened on the partition plate 81 and is used to install the connecting pipe 93.

[0051] like Figure 7 and Figure 9 As shown, a fixing plate 851 is installed on the lower part of the fixing ring 85. The vertical cross-sectional shape of the fixing plate 851 is a fan-shaped ring. The outer diameter of the fan-shaped fixing ring 85 is the same as the radius of the arc surface. Thus, during the sliding of the fixing block 944, the water flow of the fixing ring 85 can be adjusted, so that it is diverted to both sides under the interception of the fixing block 944, thereby reducing the direct impact of water flow on the control cover plate 95.

[0052] In the process of working, during the early stage of road construction, the rainwater and sewage pipe 3 is connected to the urban road sewer system. The sewage discharge pipe 6 leads to the sewage treatment plant, and the rainwater direct pipe 5 leads to the rainwater treatment station and is discharged. The protective shell 2 is installed underground, and then the protective cover 1 is installed on the protective shell 2.

[0053] On sunny days or when rainfall is light: sewage (which may be mixed with some rainwater) enters the transition cavity 82 through the rainwater and sewage co-flow pipe 3. At this time, the control cover 95 is placed at an angle directly above the through hole 86, and the adjusting plate 964 is at the top of the through groove 852. After passing through the fixing ring 85, the sewage enters the transition cavity 82 from both sides of the adjusting plate 964, and then flows down through the through hole 86 and is discharged from the sewage discharge pipe 6.

[0054] When rainfall is heavy: rainwater first enters the transition chamber through the combined rainwater and sewage pipe 3. Excess rainwater enters the rainwater direct pipe 5 through the connecting bridge pipe 4, and then enters the rainwater chamber 83. The water level in the rainwater chamber 83 continues to rise. Under the buoyancy of the rainwater chamber 83, the float 92 drives the rack 922 to move upward. The rotating gear 913 rotates under the meshing of the rack 922, driving the rotating rod 941 to rotate at a certain angle. The control cover 95 fixed at one end of the rotating rod 941 moves downward, thus fitting against the through hole 86 and closing the through hole 86. Rainwater can be diverted from the connecting pipe 93 in the transition chamber into the collecting chamber 84. This achieves rapid drainage through dual pipes when rainfall is heavy. The rainwater in the collecting chamber 84 is discharged through the rainwater drain pipe 7.

[0055] The foregoing description is merely illustrative of this disclosure, and modifications may be made to the invention in light of the above detailed description. The terminology used in the appended claims should not be construed as limiting the invention to the specific embodiments disclosed in the specification. Rather, the scope of the invention will be fully defined by the appended claims, which will be interpreted according to established principles of claim interpretation.
