Description

Technical Field

[0001] This application relates to the field of rainwater diversion, and in particular to a rainwater diversion well for urban roads. Background Technology

[0002] Sponge city is a new generation of urban stormwater management concept. It refers to a city that can be like a sponge, with good elasticity in adapting to environmental changes and coping with natural disasters caused by rainwater. When it rains, it can absorb, store, infiltrate, and purify water, and release and utilize the stored water when needed, so as to realize the free migration of rainwater in the city.

[0003] Currently, rainwater diversion wells are frequently used in the treatment of rainwater in sponge cities to facilitate the diversion of rainwater. Existing rainwater diversion wells generally achieve basic diversion effects in practical applications. However, to filter rainwater during use, filter screens are typically installed inside the wells to prevent excessive impurities in the rainwater from clogging the pipes during discharge.

[0004] However, due to the long-term filtration of rainwater, too many impurities will accumulate on the filter screen. Once too many impurities accumulate, the drainage speed of rainwater will decrease. As a result, when the rainfall is heavy, the diversion well will not be able to drain the rainwater in time, causing the rainwater to overflow the diversion well and accumulate on the road. Summary of the Invention

[0005] To address the problem that excessive accumulation of impurities reduces the drainage rate of rainwater, causing the diversion well to overflow and accumulate on the road during periods of heavy rainfall, this application provides a rainwater diversion well for urban roads.

[0006] This application provides a stormwater drainage well for urban roads, employing the following technical solution:

[0007] A stormwater drainage manhole for urban roads includes: a drainage manhole and a manhole cover on top of the drainage manhole. A filter screen is fixedly installed inside the drainage manhole. A receiving plate is fixedly fitted outside the drainage manhole. A waste bin is slidably fitted outside the drainage manhole and placed on the receiving plate. A sewage outlet and a clearance hole are respectively opened through the two opposite inner sidewalls of the drainage manhole. Two notches corresponding to and connected to the sewage outlet and the clearance hole are opened through the waste bin. A sweeping mechanism is provided between the drainage manhole and the waste bin.

[0008] By adopting the above technical solution, during rainfall, the sweeping mechanism will automatically clean the impurities on the filter screen. The impurities can be pushed into the waste bin for storage through the sewage outlet and clearance hole. This not only cleans the impurities on the filter screen so that the diversion well can quickly discharge rainwater during heavy rainfall, thus preventing it from overflowing and accumulating on the road, but also stores the impurities in the waste bin. This eliminates the need for workers to frequently walk to the road and open each manhole cover to clean the impurities on the filter screen, thereby reducing manpower consumption.

[0009] Optionally, the sweeping mechanism includes a sweeping assembly, which includes a push plate, a push rod, a limiting frame, a waist-shaped ring, a connecting column, a rotating disk, and a rotating shaft. The rotating shaft is rotatably installed inside the waste bin and is coaxially fixed with the rotating disk. One end of the connecting column is fixed to the rotating disk, and the other end passes through the waist-shaped ring. The limiting frame is fixed in the notch near the clearance hole. One end of the push rod is fixed to the waist-shaped ring, and the other end passes through the limiting frame and is fixed to the push plate.

[0010] By adopting the above technical solution, the drive shaft drives the rotating disk to rotate, and because it is connected to the limit of the waist ring, the push rod will drive the push plate to reciprocate in the horizontal direction, so that the push plate can clean the impurities on the filter screen.

[0011] Optionally, the sweeping mechanism further includes a transmission assembly, which includes a transmission rod, a drive gear, and a driven gear. One end of the transmission rod is rotatably mounted inside the waste bin, and the other end passes through the side wall of the waste bin. The drive gear is coaxially sleeved on the transmission rod, and the driven gear is coaxially sleeved on the rotating shaft. The drive gear and the driven gear mesh with each other.

[0012] By adopting the above technical solution, the drive rod is rotated, and the rotation of the drive rod will sequentially drive the rotation of the driving gear and the driven gear. The rotation of the driven gear can drive the rotating shaft to rotate.

[0013] Optionally, the push-purge mechanism further includes a drive assembly, which includes a guide plate, a rotating rod, and a blade. The guide plate is fixed inside the diversion well and is inclined. The rotating rod is rotatably installed inside the diversion well and penetrates the side wall of the diversion well. The blade is fixed to the rotating rod. The rotating rod and the transmission rod are connected by a connecting assembly.

[0014] By adopting the above technical solution, when rainwater flows into the diversion well, it flows down the guide plate after being filtered by the filter screen. Due to the setting of the guide plate, the rainwater will hit the blade, so that the blade always turns to one side and drives the rotating rod to rotate. Then, due to the setting of the connecting component, the rotating rod can drive the transmission rod to rotate.

[0015] Optionally, the connecting assembly includes a connecting rod and a connecting spring. The end wall of the transmission rod has a receiving hole, and the end wall of the rotating rod has a connecting hole. One end of the connecting rod is disposed in the receiving hole, and the other end is disposed in the connecting hole. The top of the connecting rod is provided with a guide surface, and the connecting spring is fixed between the connecting rod and the bottom of the receiving hole.

[0016] By adopting the above technical solution, when the waste bin is fitted onto the diversion well, the receiving hole and the connecting hole are coaxial, and the connecting rod can be pushed into the connecting hole by the elastic force of the connecting spring to complete the connection between the rotating rod and the transmission rod. When the rotating rod rotates, the transmission rod can rotate accordingly. When it is necessary to clean the impurities in the waste bin, the waste bin can be lifted upward from the diversion well. At this time, the connecting rod can be pressed into the receiving hole by the setting of the guide surface, so that the waste bin can be easily removed from the diversion well.

[0017] Optionally, a rain-collecting assembly is provided in the diversion well. The rain-collecting assembly includes a rain-collecting part and a sliding part. The rain-collecting part includes a rain-collecting plate, a stopper plate, and a rubber sleeve. The rain-collecting plate is fixed in the diversion well and located between the filter screen plate and the guide plate. A water outlet hole is formed through the rain-collecting plate. The stopper plate is fixed in the diversion well, and when the weight of the rainwater above the rain-collecting plate is small, the stopper plate is inserted into the water outlet hole. The rubber sleeve is fitted on the stopper plate and abuts against the inner wall of the water outlet hole. The sliding part is disposed between the rain-collecting plate and the inner wall of the diversion well.

[0018] By adopting the above technical solution, when the weight of rainwater above the rain cover is small, the plug is inserted into the water outlet so that the rainwater accumulates above the rain cover instead of flowing directly onto the guide plate.

[0019] Optionally, the sliding part includes: a slider and a return spring. The inner sidewall of the diversion well is provided with a groove. The slider is slidably connected in the groove and can slide in the vertical direction. The slider is fixedly connected to the rain cover plate. The return spring is fixed between the slider and the inner bottom wall of the groove.

[0020] By adopting the above technical solution, during rainfall, rainwater continuously accumulates on the rain catcher plate. As the weight of the rainwater increases, the slider will slide downwards in the vertical direction, thus squeezing the return spring. When the weight of the rainwater reaches a certain value, the plug plate will separate from the water outlet hole, and the rainwater on the rain catcher plate will flow towards the guide plate. If the weight of the rainwater decreases, the return spring will push the slider upwards in the vertical direction, so that the plug plate can be inserted back into the water outlet hole, thereby sealing the water outlet hole.

[0021] Optionally, the bottom of the waste bin is provided with a base plate, a rotating rod is rotatably installed on the inner side wall of the waste bin, and a stirring blade is fixedly installed on the rotating rod. A linkage assembly is provided between the base plate and the transmission rod.

[0022] By adopting the above technical solution, when the transmission rod rotates, the base plate will rotate due to the linkage component. During the rotation of the base plate, the stirring blade can come into contact with the impurities on the base plate, thereby scraping the impurities on the base plate so that the impurities on the base plate are not easy to accumulate together, and can be evenly spread on the base plate, thus greatly increasing the impurity storage capacity.

[0023] Optionally, the linkage assembly includes: a first gear, a second gear, a third gear, a fourth gear, and a linkage rod. The inner sidewall of the waste bin is provided with a clearance groove. The end of the transmission rod away from the rotating rod is rotatably installed in the clearance groove and is coaxially fixed with the first gear. The linkage rod is rotatably installed in the clearance groove, with one end coaxially fixed with the second gear and the other end coaxially fixed with the third gear. The fourth gear is sleeved on the base plate. The first gear meshes with the second gear, and the third gear meshes with the fourth gear.

[0024] By adopting the above technical solution, when the transmission rod rotates, the rotation of the transmission rod will sequentially drive the rotation of the first gear, the second gear, the linkage rod, the third gear, the fourth gear and the base plate. The rotation of the base plate will facilitate the stirring blades to scrape the impurities on the base plate.

[0025] Optionally, the inner bottom wall of the waste bin is provided with multiple receiving grooves, and ball bearings are provided in the receiving grooves. The bottom plate abuts against the ball bearings. The inner side wall of the waste bin is provided with a limiting groove. A limiting block is fixedly provided on the inner wall of the bottom plate, and the limiting block is slidably connected in the limiting groove.

[0026] By adopting the above technical solution, the ball bearings can reduce the friction force on the base plate when it rotates, so that even as impurities in the waste bin continue to increase, the base plate can still rotate, thus preventing the base plate from becoming unable to rotate due to excessive weight of impurities.

[0027] In summary, this application includes at least one of the following beneficial effects:

[0028] 1. The sweeping mechanism will automatically clean the impurities on the filter screen, and the impurities can be pushed into the waste bin for storage through the sewage outlet and clearance hole. This not only cleans the impurities on the filter screen, but also allows the diversion well to quickly discharge rainwater during heavy rainfall, thus preventing it from overflowing and accumulating on the road.

[0029] 2. During rainfall, rainwater continuously accumulates on the rain catch plate. As the weight of the rainwater increases, the slider will slide downwards in the vertical direction, thus squeezing the return spring. Once the weight of the rainwater reaches a certain value, the stopper plate will separate from the water outlet, and the rainwater on the rain catch plate will flow towards the guide plate.

[0030] 3. When the transmission rod rotates, the base plate will rotate due to the linkage component. During the rotation of the base plate, the stirring blades can come into contact with the impurities on the base plate, thereby scraping the impurities on the base plate so that they do not easily accumulate together and can be evenly spread on the base plate, thus greatly increasing the impurity storage capacity.

[0037] This application provides a stormwater diversion well for urban roads.

[0038] See Figure 1 A typical urban road rainwater diversion well may include: a diversion well 1 and a manhole cover 11 covering the top of the diversion well 1. In this embodiment, the diversion well 1 is square. A sewage pipe 12 and an outlet pipe 13 are connected to the diversion pipe, and the outlet pipe 13 is located above the sewage pipe 12. The sewage pipe 12 is used to discharge initial rainwater; the outlet pipe 13 is used to discharge later clean rainwater, so as to facilitate the utilization of rainwater and achieve the effect of saving water resources.

[0039] See Figure 2 and Figure 3A partition block is fixedly installed inside the diversion well 1. The top wall of the partition block has a through hole, and the bottom wall of the partition block has a pair of inclined surfaces, which are symmetrically arranged. A float is installed inside the diversion well 1, located on the inner bottom wall. A fixing plate, shaped like an "L," is fixedly installed on the inner side wall of the diversion well 1. A float plate is slidably connected to the fixing plate and slides vertically. The float plate abuts against the inner side wall of the diversion well 1, sealing the discharge pipe 13. As the rainfall duration and amount increase, the sewage pipe 12 will be under load. Consequently, rainwater will accumulate in the diversion well 1, causing the water level to gradually rise. As the water level in the diversion well 1 rises, the float and float plate will float upwards. After floating, the float will engage between the two inclined surfaces to seal the through hole; after floating, the float plate will open the discharge pipe 13, allowing clean rainwater to be discharged through the discharge pipe 13.

[0040] See Figure 3 A filter screen 17 is fixedly installed inside the diversion well 1. The filter screen 17 can filter rainwater, thereby improving the quality of rainwater. A receiving plate 18 is fixedly sleeved on the outside of the diversion well 1. A waste box 2 is slidably sleeved on the outside of the diversion well 1 and placed on the receiving plate 18, that is, the waste box 2 can be removed from the diversion well 1. In this embodiment of the application, the top of the waste box 2 is provided with a cover so that the waste box 2 can be opened later to clean the impurities inside the waste box 2.

[0041] See Figure 3 , Figure 4 and Figure 5 The inner walls of the diversion well 1 are respectively provided with a sewage outlet 15 and a clearance hole 16. The inner wall of the waste bin 2 near the diversion well 1 has a pair of notches 21 that are connected to and correspond one-to-one with the sewage outlet 15 and the clearance hole 16. A sweeping mechanism is provided between the diversion well 1 and the waste bin 2. During rainfall, the sweeping mechanism will automatically clean the impurities on the filter screen 17. The impurities can be swept into the waste bin 2 through the sewage outlet 15 and the clearance hole 16 for storage. This not only cleans the impurities on the filter screen 17, so that the diversion well 1 can quickly discharge rainwater during heavy rainfall, thus preventing it from overflowing and accumulating on the road, but also stores the impurities in the waste bin 2. This eliminates the need for workers to frequently walk to the road and open each manhole cover 11 to clean the impurities on the filter screen 17, thereby reducing manpower consumption.

[0042] See Figure 3 , Figure 4 and Figure 5 The sweeping mechanism includes: sweeping component 3, transmission component 4 and drive component 5.

[0043] See Figure 3 and Figure 4 The push-broom assembly 3 includes: a push plate 31, a push rod 32, a limiting frame, a waist-shaped ring 33, a connecting post 34, a rotating disk 35, and a rotating shaft 36. The rotating shaft 36 is rotatably installed inside the waste bin 2, located at any notch 21 and vertically positioned. The rotating disk 35 is coaxially fixed with the rotating shaft 36. One end of the connecting post 34 is fixed to the top wall of the rotating disk 35, and the other end passes through the waist-shaped ring 33. The limiting frame is fixed in the notch 21 near the clearance hole 16. One end of the push rod 32 is fixed to the waist-shaped ring 33, and the other end passes through the limiting frame and is fixed to the push plate 31. The initial position of the push plate 31 is located in the notch 21 near the clearance hole 16. The limiting frame can limit the push rod 32, thereby enabling the push rod 32 to reciprocate stably in the horizontal direction.

[0044] See Figure 3 The transmission assembly 4 includes a transmission rod 41, a driving gear 42, and a driven gear 43. One end of the transmission rod 41 is rotatably mounted inside the waste container 2 and located below the rotating shaft 36, while the other end passes through the side wall of the waste container 2 near the diversion well 1. The driving gear 42 is coaxially sleeved on the transmission rod 41, and the driven gear 43 is coaxially sleeved on the rotating shaft 36, with the driving gear 42 and the driven gear 43 meshing with each other.

[0045] See Figure 3 and Figure 5 The drive assembly 5 includes a guide plate 51, a rotating rod 52, and a blade 53. The guide plate 51 is fixed inside the diversion well 1 and located below the filter screen plate 17. The guide plate 51 is inclined, with one end of the guide plate 51 away from the inner sidewall of the diversion well 1 tilting downwards. The rotating rod 52 is rotatably installed inside the diversion well 1 and is horizontally arranged. One end of the rotating rod 52 passes through the sidewall of the diversion well 1 and is connected to the transmission rod 41 through the connecting assembly 6, while the other end is fixed to the blade 53. In this embodiment, multiple blades 53 are provided, and the multiple blades 53 are evenly distributed along the circumference of the rotating rod 52. The guide plate 51 is located above the blades 53.

[0046] When the waste bin 2 is installed on the diversion well 1, the rotating rod 52 is coaxial with the transmission rod 41. When rainwater flows into the diversion well 1, the rainwater flows down onto the guide plate 51 after being filtered by the filter screen 17. Due to the setting of the guide plate 51, the rainwater will hit the blade 53, so that the blade 53 always rotates to one side, driving the rotating rod 52 to rotate.

[0047] The rotation of the rotating rod 52 sequentially drives the transmission rod 41, the driving gear 42, the driven gear 43, the rotating shaft 36, and the rotating disk 35 to rotate. The rotation of the rotating disk 35 drives the push rod 32 to reciprocate in the horizontal direction, thereby pushing the push plate 31 to reciprocate on the filter screen 17 to clean impurities on the filter screen 17. The entire cleaning process requires no electrical equipment, thus achieving energy savings.

[0048] See Figure 5 The connecting assembly 6 includes a connecting rod 61 and a connecting spring 62. The end wall of the transmission rod 41 near the rotating rod 52 has a receiving hole 411, and the end wall of the rotating rod 52 near the transmission rod 41 has a connecting hole 521. One end of the connecting rod 61 is disposed within the receiving hole 411, and the other end is disposed within the connecting hole 521. The connecting rod 61 is square in shape. One end of the connecting spring 62 is fixed to the end wall of the connecting rod 61 away from the rotating rod 52, and the other end is fixed to the bottom of the receiving hole 411. The connecting spring 62 is used to push the connecting rod 61 into the connecting hole 521, thereby completing the connection between the transmission rod 41 and the rotating rod 52.

[0049] See Figure 5 A guide surface 611 is provided on the top wall of the end of the connecting rod 61 away from the connecting spring 62. The guide surface 611 is inclined and the end away from the connecting spring 62 is inclined downward. The end of the guide surface 611 near the connecting spring 62 is lower than the opening of the connecting hole 521. The guide surface 611 facilitates pressing the connecting rod 61 into the receiving hole 411. When the waste box 2 is sleeved on the diversion well 1, the receiving hole 411 and the connecting hole 521 are coaxial. Through the elastic force of the connecting spring 62, the connecting rod 61 can be pushed into the connecting hole 521 to complete the connection between the rotating rod 52 and the transmission rod 41. When the rotating rod 52 rotates, the transmission rod 41 can rotate accordingly.

[0050] When it is necessary to clean the impurities in the waste bin 2, the waste bin 2 can be lifted upward from the diversion well 1. At this time, the connecting rod 61 can be pressed into the receiving hole 411 through the setting of the guide surface 611, so that the waste bin 2 can be removed from the diversion well 1.

[0051] See Figure 3 Furthermore, a bottom plate 25 is provided at the inner bottom of the waste bin 2, and the bottom plate 25 can rotate on its own. A rotating rod 26 is rotatably installed on the inner side wall of the waste bin 2 near the diversion well 1, and the rotating rod 26 is vertically arranged. A stirring blade 261 is fixedly provided at the bottom end of the rotating rod 26, and the stirring is also located above the bottom plate 25.

[0052] See Figure 3A linkage component 9 is provided between the base plate 25 and the transmission rod 41. When the transmission rod 41 rotates, the base plate 25 will rotate through the linkage component 9. During the rotation of the base plate 25, the stirring blade 261 can come into contact with the impurities on the base plate 25, thereby scraping the impurities on the base plate 25 so that the impurities on the base plate 25 are not easy to accumulate together, so that they can be evenly spread on the base plate 25, thereby greatly increasing the impurity storage capacity.

[0053] See Figure 3 The linkage assembly 9 includes a first gear 91, a second gear 92, a third gear 93, a fourth gear 94, and a linkage rod 95. A clearance groove 23 is provided on the inner wall of the waste bin 2 on the side away from the diversion well 1. The end of the transmission rod 41 away from the rotating rod 52 is rotatably installed in the clearance groove 23 and is coaxially fixed with the first gear 91. The linkage rod 95 is rotatably installed in the clearance groove 23 and is vertically arranged. One end of the linkage rod 95 near the transmission rod 41 is coaxially fixed with the second gear 92, and the other end is fixed with the third gear 93.

[0054] See Figure 3 The fourth gear 94 is fixedly sleeved on the base plate 25, and the first gear 91 meshes with the second gear 92, and the third gear 93 meshes with the fourth gear 94. In this embodiment, the first gear 91 and the second gear 92 are bevel gears, and the third gear 93 and the fourth gear 94 are spur gears. When the transmission rod 41 rotates, the rotation of the transmission rod 41 will sequentially drive the rotation of the first gear 91, the second gear 92, the linkage rod 95, the third gear 93, the fourth gear 94, and the base plate 25. The rotation of the base plate 25 will facilitate the stirring blade 261 to scrape the impurities on the base plate 25.

[0055] See Figure 3 In addition, the inner bottom wall of the waste bin 2 is provided with multiple receiving grooves 24, and ball bearings 241 are provided in the receiving grooves 24. The ball bearings 241 abut against the bottom wall of the bottom plate 25. The ball bearings 241 can reduce the friction force on the bottom plate 25 when it rotates. As impurities in the waste bin 2 continue to increase, the bottom plate 25 can also rotate, so that the bottom plate 25 is not likely to fail to rotate due to excessive weight of impurities.

[0056] See Figure 3 The inner wall of the waste bin 2 near the diversion well 1 has a limiting groove 22 along the circumference of the waste bin 2. A limiting block 251 is fixedly installed on the inner wall of the bottom plate 25, and the limiting block 251 is slidably connected in the limiting groove 22. The limiting block 251 can limit the bottom plate 25 so that the bottom plate 25 can rotate more stably and is less prone to tilting.

[0057] See Figure 3An annular baffle 252 is fixedly provided on the top wall of the end of the base plate 25 away from the limiting block 251, and the end of the baffle 252 away from the base plate 25 abuts against the inner side wall of the waste bin 2 away from the diversion well 1. The baffle 252 can prevent impurities from falling into the fourth gear 94, thereby preventing the base plate 25 from being unable to rotate.

[0058] See Figure 5 Furthermore, a rain-collecting component is installed inside the diversion well 1. When the rainfall is small, the rainwater will not flow directly down the guide plate 51, but will accumulate on the rain-collecting component. When the rainwater reaches a certain weight, the rain-collecting component will automatically release the rainwater, which will make it easier to hit the blade 53 and drive the blade 53 to rotate, making it easier to clean the filter screen 17 and drive the bottom plate 25 to rotate.

[0059] See Figure 5 The rain-catching assembly includes: a rain-catching part 7 and a sliding part 8.

[0060] See Figure 5 The rain-collecting section 7 includes a rain-collecting plate 71, a stopper plate 72, and a rubber sleeve 73. The rain-collecting plate 71 is fixed inside the diversion well 1 and located between the filter screen plate 17 and the guide plate 51. A water outlet hole 711 is provided through the top wall of the rain-collecting plate 71. The stopper plate 72 is fixed inside the diversion well 1. When the weight of the rainwater above the rain-collecting plate 71 is small, the stopper plate 72 is inserted into the water outlet hole 711 so that the rainwater accumulates above the rain-collecting plate 71 and does not flow directly onto the guide plate 51.

[0061] See Figure 5 The rubber sleeve 73 is fitted onto the plug plate 72 and is tightly pressed against the inside of the water outlet 711. The rubber sleeve 73 can improve the sealing between the plug plate 72 and the inner wall of the water outlet 711, so that rainwater is less likely to leak onto the guide plate 51.

[0062] See Figure 5 The sliding part 8 includes a slider 81 and a return spring 82. The two inner sidewalls of the diversion well 1 are provided with grooves 14. The slider 81 is slidably connected within the grooves 14 and can slide vertically. The slider 81 is fixedly connected to the sidewall of the rain catch plate 71. One end of the return spring 82 is fixed to the bottom wall of the slider 81, and the other end is fixed to the inner bottom wall of the groove 14. During rainfall, rainwater continuously accumulates on the rain catch plate 71. As the weight of the rainwater increases, the slider 81 will slide downwards vertically, thus squeezing the return spring 82. Until the weight of the rainwater reaches a certain value, the stopper plate 72 will separate from the water outlet 711, allowing the rainwater on the rain catch plate 71 to flow onto the guide plate 51.

[0063] If the weight of the rainwater decreases, the return spring 82 will push the slider 81 to slide upward in the vertical direction, so that the plug plate 72 can be inserted into the water outlet 711 again, thereby sealing the water outlet 711.

[0064] The working principle of a rainwater diversion well for urban roads in this application is as follows: When rainwater flows into the diversion well 1, the rainwater is filtered by the filter screen 17 and then flows onto the guide plate 51; due to the setting of the guide plate 51, the rainwater will hit the blade 53, so that the blade 53 always rotates to one side, driving the rotating rod 52 to rotate.

[0065] The rotation of the rotating rod 52 will sequentially drive the transmission rod 41, the driving gear 42, the driven gear 43, the rotating shaft 36 and the rotating disk 35 to rotate. The rotation of the rotating disk 35 will drive the push rod 32 to reciprocate in the horizontal direction, thereby pushing the push plate 31 to reciprocate on the filter screen plate 17 to clean the impurities on the filter screen plate 17.

[0066] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
