Description

Technical Field

[0001] The invention belongs to the technical field of road surface drainage, and in particular relates to a road surface drainage device for urban construction planning. Background Art

[0002] Pavement drainage plays a vital role in urban construction planning. It not only directly affects the infrastructure function of the city, but also has a profound impact on the quality of life and public safety of residents. If the water on the road surface is difficult to drain normally for a long time, it will accumulate and infiltrate on the road surface, which may cause the roadbed to settle and deform, and increase the risk of road collapse. Therefore, a good road drainage system can ensure that rainwater and other liquids are quickly discharged to avoid puddles and puddles caused by accumulated water, which is not only conducive to vehicle driving safety, but also prolongs the service life of the highway. In addition, in the face of extreme weather such as heavy rain, efficient drainage facilities can drain accumulated water in time to prevent the road surface from being flooded, thereby reducing vehicle damage, casualties and property losses.

[0003] The most critical reason for road waterlogging is the blockage of road drainage outlets. Currently, drainage devices installed on the road are mostly one-piece drainage structures such as grates installed at the drainage outlets. In order to improve the drainage effect, the drainage holes on the grates are often large in size. Therefore, dead branches and leaves of roadside trees or mud and gravel on the ground often enter the drainage channel through the drainage holes on the grates. After long-term use, the debris accumulated in the drainage channel will cause siltation, affecting the drainage performance. Workers are required to enter the drainage channel regularly to clean up the debris, which brings inconvenience. In order to facilitate the cleaning of debris, the existing drainage device will install a filter net or a filter tank under the grate. When cleaning, the grate is directly opened to take out the filter net or the filter tank to remove the debris. Although this device can intercept impurities from entering the drainage channel and avoid clogging the drainage channel, if a large amount of debris is accumulated in the filter net or the filter tank, it will affect the drainage flow rate of the drainage outlet per unit time, and the drainage speed will slow down. In the face of extreme weather such as heavy rain or rainstorms, it is easy to cause the road surface to be flooded, affecting the driving of vehicles. Even if some sections of the road cannot be removed in time, it is easy to cause torrents, causing damage to some infrastructure on the road surface or personnel safety risks. For example, the Chinese patent with the publication number CN219157401U provides a double-layer bridge drainage hole grate, including a cover plate, a plurality of first drainage holes are opened on the cover plate, a sleeve is provided at the bottom of the cover plate, a water filter net is provided at the bottom of the sleeve, the water filter net is hemispherical, the center position of the filter net is raised toward the direction of the cover plate, and a plurality of second drainage holes are opened on the water filter net. In the device, the cover plate and the first drainage hole on the cover plate form a structure similar to a traditional grate, and a hemispherical water filter net is arranged at the bottom of the grate, which can intercept and block the debris entering from the first drainage hole. Although the water filter net can disperse the impurities on the surrounding side of the water filter net after intercepting the debris by using the hemispherical structure to reduce the obstruction to the water flow, when there are too many impurities, the water filter net will still be blocked to varying degrees, resulting in a smaller drainage flow rate, and the accumulated water on the road surface cannot be removed in time, causing the road surface to be flooded. Another example is a Chinese patent with publication number CN219808459U, which provides a road drainage device, including a drainage pipe, a pipe cover is hinged on the side of the top end of the drainage pipe, and a lifting mechanism is provided inside the drainage pipe; the lifting mechanism includes a concave opening opened on both sides of the inner wall of the drainage pipe, the inner walls of the concave openings are slidably connected with protrusions, the inner wall of the drainage pipe is inserted and connected with a filter screen frame, one end of the protrusion is fixedly connected to the filter screen frame, a movable opening is opened on one side of the inner wall of the concave opening, the inner wall of the movable opening is inserted and connected with a first connecting rod, and the bottom of the outer wall of the first connecting rod is hinged with a second connecting rod.During the use of the device, the garbage is blocked into the filter frame through the filter frame. Compared with the patent CN219808459U, when there is too much garbage, the water flow acts on the float to push the folding rod to move the fixed bar along the through-hole and raise it, so that the marking arrow exposes the pipe cover, and promptly reminds the staff to clean up the garbage. However, when the staff does not find or arrive, the blockage of the filter frame will still cause the drainage flow to become smaller, and the accumulated water on the road surface cannot be removed in time, causing the road surface to be flooded. Another example is the invention patent with the publication number CN110984335B, which provides a drainage filtration system for a municipal engineering road, including a drainage pipe arranged under the road; a vertical shaft connecting the drainage pipe and the road surface and having a manhole cover installed on the top; a symmetrical vertical plate detachably installed between the inner walls of the vertical shaft; a flow limiting device installed between the relative inner sides of the vertical plate near the wellhead to limit the amount of debris entering the vertical shaft; a separation device horizontally installed on the side of the vertical plate away from the wellhead to separate the debris and sewage passing through the flow limiting device, wherein the separation device includes a sieve plate horizontally installed on the vertical plate and a sieve installed in the sieve mouth, and a net bag is also arranged on the upper side of the sieve. The device uses the sieve plate, the sieve and the net bag to filter rainwater or other sewage flowing into the drainage pipe to ensure smooth water flow inside the drainage pipe, but after a large amount of impurities accumulate on the sieve plate, the sieve and the net bag, the unit flow of water flowing to the drainage pipe will be reduced, the drainage speed will be slowed down, and the normal drainage performance will be affected, causing the accumulation of surface water on the road surface, flooding the road surface, affecting vehicle driving, and even causing damage to infrastructure or bringing risks to pedestrian safety.

The transmission shaft 33 is rotatably connected to the support arm 35. The end of the support arm 35 away from the transmission shaft 33 is fixedly connected to the corresponding side plate 34. The impeller 32 is fixed on the transmission shaft 33. The blades 321 on the impeller 32 close to the guide plate 31 are placed on the lower side of the guide plate 31, so that the water flow out of the guide plate 31 acts on the blades 321 to realize the rotation of the transmission shaft 33.

[0047] See also Figures 3 to 6As shown, the impurity removal component 4 includes a transmission belt 41, a cleaning brush 42, a collection tank 43 and two rotating rods 44. The two rotating rods 44 are respectively arranged at the two ends of the filter plate 2, the rotating rods 44 are parallel to the transmission shaft 33, and the two transmission shafts 33 are spaced apart from the ends of the filter plate 2. The rotating rods 44 are rotatably connected to the two side plates 34. Then, the transmission belt 41 is wrapped around the two rotating rods 44, and the transmission belt 41 and the rotating rods 44 are connected through a pulley. Preferably, the diameter of the pulley is greater than the thickness of the filter plate 2, so that the filter plate 2 is placed inside the transmission belt 41. A plurality of cleaning brushes 42 are further arranged. The cleaning brush 42 is evenly distributed on the transmission belt 41 in the horizontal direction, and the cleaning brush 42 is fixedly connected to the transmission belt 41, and the collecting trough 43 is placed on the side of the filter plate 2 away from the transmission shaft 33, and a plurality of filtering holes are opened on the bottom wall of the collecting trough 43; preferably, during installation, on the one hand, a minimum spacing is designed between the upper end of the guide plate 31 in the inclined direction and the filter plate 2, and the minimum spacing can adapt to the operation of the transmission belt 41 and the cleaning brush 42; on the other hand, at least two transmission belts 41 are preferably set, and during installation, the two transmission belts 41 are arranged on both sides of the filter plate 2, so as to ensure the stability of the cleaning brush 42, and facilitate the cleaning of the debris on the filter plate 2. Further, for the design requirements, it is necessary to ensure that the filter plate 2 is in a horizontal state.

[0048] See also Figure 3 and Figure 5 As shown, the transmission part 5 can be preferably a combination of a chain 51 and a sprocket 52, or a combination of a pulley and a belt. In order to ensure the stability of the transmission, the device preferably combines a chain 51 and a sprocket 52.

Therefore, the transmission part 5 formed by the sprocket 52 and the chain 51 can realize that the transmission shaft 33 drives the rotating rod 44 to rotate, and the combination of the sprocket 52 and the chain 51 can ensure that the rotation directions of the transmission shaft 33 and the rotating rod 44 are consistent, that is, after the water flow on the guide plate 31 acts on the impeller 32 to drive the transmission shaft 33 to rotate, the two rotating rods 44 drive the transmission belt 41 on the upper side of the filter plate 2 to always move toward the side of the collection trough 43 under the cooperation of the pulley, so that the transmission belt 41 can carry the cleaning brush 42 to clean the impurities on the filter plate 2 into the collection trough 43.

[0049] See also Figure 5 and Figure 8As shown, further, in order to ensure the normal drainage performance of the drainage device, a water trough 6 is opened on the guide plate 31 along the inclined direction, and the side walls of the guide plate 31 on both sides of the notch of the water trough 6 are inclined, and the lower end of the water trough 6 is placed on the upper side of the impeller 32. After the water flow falls from the filter plate 2, it passes through the inclined side walls on both sides of the notch of the water trough 6, which can fully converge the water flow in the water trough 6, so that the water flow can act more concentratedly on the impeller 32, so that the impeller 32 can fully utilize the power of the water flow to drive the transmission shaft 33 to rotate continuously, so as to facilitate the indirect driving of the transmission belt 41 to continue to operate, so that the cleaning brush 42 removes the debris on the filter plate 2, maintains the drainage performance of the device, and avoids the reduction of the unit drainage flow.

[0050] See also Figure 3 and Fig.11 As shown, further, in order to ensure the normal drainage performance of the drainage device, a baffle 9 is provided on the side of the guide plate 31 close to the impeller 32. The upper end of the baffle 9 is fixedly connected to the two side plates 34, and a gap is provided between the lower end and the guide plate 31. The lower end of the baffle 9 is placed between the transmission shaft 33 and the guide plate 31. The baffle 9 is used to guide the water flowing out of the water tank 6 to the same side of the impeller 32. The baffle 9 can ensure that the water flow on the guide plate 31 is all forced onto the blades 321 on the side of the impeller 32 close to the guide plate 31, thereby ensuring that the water flow pushes the impeller 32 to move stably in one direction, so that the cleaning brush 42 continues to work to clean the filter plate 2, maintain the cleanliness of the filter plate 2, and maintain the normal water filtering performance of the filter plate 2.

[0051] See also Figure 4 and Figure 7As shown, further, in order to ensure the normal drainage performance of the drainage device. The cleaning brush 42 is further structurally designed, specifically: the cleaning brush 42 is composed of bristles 421 and a collecting groove 422, the notch of the collecting groove 422 faces the filter plate 2, the collecting groove 422 is fixed on the transmission belt 41, and the collecting groove 422 is made of a filter screen, the bristles 421 are fixed on the bottom wall of the collecting groove 422 along the length direction of the collecting groove 422, and the bristles 421 extend from the notch of the collecting groove 422 on one side away from the bottom wall of the collecting groove 422 to contact the filter plate 2. Preferably, the side walls of the collecting groove 422 located on both sides of the bristles 421 are designed in an inverted eight-character shape. The design of the collecting groove 422 can be used to collect impurities cleaned from the filter plate 2 by the cleaning brush 42 when the cleaning brush 42 turns to the bottom of the filter plate 2, reducing the impurities falling from the cleaning brush 42 during the cleaning process at the bottom of the filter plate 2 and being carried to the position of the impeller 32 by the water flow, affecting the normal operation of the impeller 32. Preferably, when the collecting tank 422 is turned to the upper side of the filter plate 2, the impurities collected at the bottom are placed on the upper side of the filter plate 2, and then the bristles 421 are used to clean them into the collecting tank 43. Furthermore, the bristles 421 are preferably made of nylon or PBT (polybutylene terephthalate) material with good resilience, which can extend the effectiveness of the use of the bristles 421.

[0052] See also Figure 3 and Fig.10 As shown, in order to improve the cleaning effect of the filter plate 2, the debris can be cleaned more thoroughly and the normal drainage performance of the device can be ensured. Slots 7 are provided on the opposite side walls of the two side plates 34. The two slots 7 are arranged opposite to each other. The two ends of the filter plate 2 are respectively inserted into the corresponding slots 7. A shaking mechanism 8 is provided between one of the slots 7 and the transmission shaft 33. The output end of the shaking mechanism 8 is connected to the filter plate 2 to drive the filter plate 2 to shake horizontally between the two side plates 34. Figure 5 , Figure 8 , Fig. 9 and Fig.10As shown, specifically, the shaking assembly includes a shaped wheel 81, a movable plate 82 and a plurality of elastic members 84. The shaped wheel 81 is fixedly mounted on the transmission shaft 33, and an inclined surface is provided on the side of the shaped wheel 81 facing the impeller 32; one end of the movable plate 82 abuts against the inclined surface of the shaped wheel 81, and the other end is fixedly connected with a plurality of connecting rods 83, and the plurality of connecting rods 83 are evenly distributed along the length direction of the slot 7, and one end of the connecting rod 83 away from the movable plate 82 penetrates into the slot 7 and is fixedly connected to the filter plate 2; a plurality of elastic members 84 are arranged between the filter plate 2 and the side wall of the slot 7, and the movable plate 82 realizes the lateral reciprocating shaking of the filter plate 2 through the rotation of the shaped wheel 81 and the cooperation of the elastic members 84. During the rotation of the transmission shaft 33, the shaped wheel 81 will be synchronously driven to rotate, so that different positions on the inclined surface of the shaped wheel 81 contact the movable plate 82, so that the lateral distance difference between different positions of the inclined surface and the elastic member 84 are used to achieve lateral reciprocating motion between the two side plates 34, and the elastic member 84 is used to generate a certain lateral shaking effect, so that the bristles 421 of the cleaning brush 42 can better clean out the impurities embedded in the mesh, ensure the cleanliness of the filter plate 2, and keep the water flow rate on the filter plate 2 good with the shaking effect. At the same time, the slot 7 can be used to limit the filter plate 2 to prevent it from detaching from the side plate 34 during the left and right reciprocating motion. At the same time, the design of the slot 7 is also convenient for the removal of the filter plate 2.

[0053] See also Figure 3 As shown, further, in order to ensure the normal drainage performance of the drainage device, the impeller 32 includes a plurality of blades 321, and the blades 321 are arranged in an arc shape, and the arc mouth of the blades 321 always faces the water tank 6 when it rotates to the lower side of the water tank 6. The blades 321 arranged in an arc shape can be better pushed by the water flow, so that the impeller 32 fully utilizes the power of the water flow to maintain the rotation of the transmission shaft 33, and then the cleaning brush 42 continuously cleans the filter plate 2. In addition, the blades 321 arranged in an arc shape can also ensure that the water flow on the blades 321 flows out completely when the blades 321 rotate to the bottom of the transmission shaft 33, avoiding the increase of pressure resistance.

Preferably, a drainage port is provided at the bottom of the wind shield 10. The design of the wind shield 10 can avoid the wind force in the drainage channel from causing resistance to the rotation of the impeller 32, thereby ensuring the normal operation of the impeller 32.

[0055] See also Figure 4As shown, further, in order to ensure the normal drainage performance of the drainage device. A stabilizing rod 11 is fixedly connected to the side of each cleaning brush 42 away from the bristles 421, and the side plates 34 are provided with guide grooves 12 on the upper and lower sides of the filter plate 2. The two ends of the guide grooves 12 are in the shape of an eight-shaped opening 13. When the stabilizing rod 11 moves to the upper and lower sides of the filter plate 2, it slides in the corresponding guide groove 12. During use, the cooperation of the guide groove 12 and the stabilizing rod 11 can ensure the stability of the cleaning brush 42 moving on the upper and lower sides of the filter plate 2, and avoid the cleaning brush 42 from tilting, which affects the cleaning effect of the debris on the filter plate 2. The design of the eight-shaped opening 13 at the end of the guide groove 12 can ensure that the stabilizing rod 11 smoothly enters the guide groove 12 when it turns to the upper or lower side of the filter plate 2.

[0056] See also Fig.12 As shown, further, in order to ensure the normal drainage performance of the drainage device, a bristle cleaning tooth 14 is provided above the aggregate trough 43 and between the rotating rod 44 and the filter plate 2, and the bristle cleaning tooth 14 is fixedly connected to the side plate 34. The bristle cleaning tooth 14 is preferably set as a rake tooth structure, so that when the cleaning brush 42 runs to the opening of the aggregate trough 43, the impurities adhering to the bristles 421 are cleaned up under the action of the bristle cleaning tooth 14, so as to avoid the impurities from falling on the guide plate 31 when they turn to the bottom of the filter plate 2, thereby affecting the subsequent rotation of the impeller 32.

[0057] The implementation method of this device:

[0058] See also Figures 1 to 12As shown, when used, the original installation opening of the grate 1 on the drainage channel is not changed. After assembling the filter plate 2, power assembly 3, impurity removal assembly 4 and transmission part 5 at the bottom of the grate 1, the bottom integral component of the grate 1 is placed inside the drainage channel through the installation opening of the grate 1, and one side of the impeller 32 is placed at the rear side of the water flow direction of the drainage channel to ensure that the water flowing down from the guide plate 31 flows along with the water flow in the drainage channel. In order to facilitate the cleaning of impurities in the aggregate trough 43, a cleaning cover plate can be set on the side of the installation opening of the grate 1 in the drainage channel. When in use, the cover plate is opened to take out the aggregate trough 43 for cleaning, which is convenient and quick. During use, after rainwater enters the drainage channel from the drainage hole on the grate 1, it first passes through the filter plate 2 to intercept the sand, leaves and some solid garbage carried in the rainwater, and the filtered water flow will fall on the inclined guide plate 31. The guide plate 31 uses the inclined structure on both sides to converge the water flow into the water trough 6 in the middle of the guide plate 31. At this time, the water flow in the water trough 6 will flow to the impeller 32 along the inclined direction. Due to the arc-shaped structure of the baffle plate 9 and the blades 321 on the impeller 32, the impact of the water flow can fully act on the blades 321 on one side of the transmission shaft 33, thereby driving the transmission shaft 33 to rotate. The transmission shaft 33 then uses the cooperation of the transmission part 5, the pulley and the transmission belt 41 to make the cleaning brush 42 located on the upper side of the filter plate 2 run to the side of the collection trough 43 under the drive of the transmission belt 41, and when the cleaning brush 42 runs to the bottom of the filter plate 2 The bristles 421 can also be used to push out impurities in the mesh from the bottom of the filter plate 2, so that the cleaning brush 42 can be used to fully push the impurities intercepted on the filter plate 2 into the collection trough 43 for collection. Under the continuous fluidity of the water flow, the cleaning brush 42 can be kept continuously cleaning the filter plate 2, and then the transmission shaft 33 rotates while synchronously driving the special-shaped wheel 81 to rotate, so that different positions on the inclined surface of the special-shaped wheel 81 contact the movable plate 82, so that the lateral distance difference between the different positions of the inclined surface and the cooperation of the elastic member 84 are used to realize the lateral reciprocating motion between the two side plates 34, and the elastic member 84 is used to generate a certain lateral shaking effect, so that the bristles 421 of the cleaning brush 42 can better clean out the impurities embedded in the mesh, thereby ensuring the cleanliness of the filter plate 2; keeping the water flow rate on the filter plate 2 normal, and maintaining the normal drainage performance of the device.
