Description

Technical Field

[0001] The present invention relates to the technical field of road drainage, and in particular to a road drainage structure that can be used in industrial parks and residential areas. Background Art

[0002] Currently, existing road drainage systems within industrial parks and residential areas involve ditches dug within the road, which are connected to the municipal drainage system. Curbs are installed on both sides of the road, and drainage outlets are opened on the side of the curb facing the road. The outlets are connected to the drainage ditches and are equipped with gratings. During rainy days, accumulated water on the road flows to the drainage outlets. After filtering through the gratings, it can filter out large impurities carried by the water before being discharged into the drainage ditch and finally discharged through the municipal drainage system to rivers, oceans, and other water bodies.

[0003] This type of road drainage structure has the following problems: first, when the intensity of rainfall is high, the water accumulated on the sidewalk along the roadside cannot be quickly drained into the drainage ditch; second, because the pores of the grille are large, it can only filter out large impurities, so small impurities will still enter the drainage ditch with rainwater, such as plant materials, sand and gravel, various garbage, etc., which cannot be filtered by the grille. After entering the drainage ditch, they will be deposited at the bottom of the drainage ditch. In southern my country, due to abundant rainfall, small impurities accumulate in the drainage ditch at a very fast rate, resulting in a significant reduction in the cross-sectional area of the drainage ditch and a significant reduction in drainage efficiency. When heavy rain comes, it is easy to cause waterlogging. In addition, the desilting construction process of the drainage ditch will also affect the normal drainage function of the drainage ditch. Summary of the Invention

[0004] In view of this, an object of the present invention is to provide a road drainage structure that is beneficial to improving road drainage efficiency and can be used in industrial parks and residential areas.

[0005] The technical solution adopted by the present invention to solve the technical problem is:

A plurality of water-guiding gaps are arranged at intervals on the upper surface of the curbstone, and each water-guiding gap corresponds to a grille.

[0008] In a preferred embodiment of the present invention, the filter plate is located at the port at the head end of the water trough and is inclined toward the side where the first drainage ditch is located. A filter residue removing device capable of removing filter residue on the filter plate is provided in the road body.

[0009] The top end of the filter press is fixed with a first end in contact with the filter screen, and the bottom end of the filter press is fixed with a first end in contact with the filter screen.

[0010] In a preferred embodiment of the present invention, the transmission structure includes a first rotating block hinged in the embedded tube and located below the movable push rod, a first connecting rod connected between the movable push rod and the first rotating block, and a second connecting rod connected between the first rotating block and the top pressure plate.

[0011] In a preferred embodiment of the present invention, a cover plate is provided at the upper end of the embedded tube, a through hole is provided on the cover plate to avoid the movable push rod, and a flexible cover is provided on the upper surface of the cover plate to shield the through hole and the upper end of the movable push rod.

[0012] In a preferred embodiment of the present invention, the filter residue removing device includes a frame fixed in the first drainage ditch, a cleaning frame installed on the frame, a cleaning brush arranged on the cleaning frame, and a residue removal power device capable of driving the cleaning brush to move back and forth to clean the filter plate.

[0013] In a preferred embodiment of the present invention, the cleaning rack is movably arranged on a frame, and a retractable power device capable of driving the cleaning rack to move upward to a retracted state is provided on the frame.

[0014] In a preferred embodiment of the present invention, the frame is provided with a sliding frame and a guide structure parallel to the filter plate, the retraction and extension power device includes a retraction and extension driver capable of driving the sliding frame to slide along the guide structure, the sliding frame and the cleaning frame are connected by a plurality of third connecting rods, the frame is provided with a guide chute and a guide column, the guide column has a guide surface parallel to the guide structure, and the cleaning frame is provided with a roller located at the lower end of the guide chute, when the sliding frame slides obliquely upward along the guide structure, the roller on the cleaning frame moves out from the upper end of the guide chute and moves obliquely upward along the guide surface, so that the cleaning frame moves to a retracted state.

[0015] In a preferred embodiment of the present invention, the third connecting rods are divided into two rows, and the number of third connecting rods in each row is at least two.

[0017] The present invention has the beneficial effect of effectively draining sewage and rainstorms from roads. Typically, rainwater on sidewalks first collects in a sump. Then, rainwater in the sump flows through the water-guiding notches in the curbstones to the locations of the grates, where it flows directly through the grates into the first drain ditch, preventing it from flowing to other locations on the motorway and causing significant water accumulation. Rainwater on the motorway primarily flows through the grates into the first drain ditch, but can also flow through the first water filter holes in the manhole cover into the second drain ditch. Due to the larger pores in the grates on the first drain ditch, it can function similarly to conventional drains. During periods of high rainfall, such as heavy rain or torrential downpours, some rainwater from the first drain ditch can flow through the sump into the second drain ditch. In this case, both drains drain together, improving drainage efficiency. Due to the filtering effect of the manhole cover and filter plate, silt accumulates much less rapidly in the second drain ditch than in the first. During periods of heavy rainfall, the manhole cover on the second drain ditch can be opened, allowing the less silted second drain ditch to serve as the primary drainage channel, further improving drainage efficiency. In addition, during the dredging construction in the first drainage ditch, the second drainage ditch can play a normal drainage role and will not cause insufficient drainage efficiency due to the construction.

If the specific posture changes, the directional indication will also change accordingly. In addition, the descriptions of "preferred", "sub-preferred", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "preferred" or "sub-preferred" may explicitly or implicitly include at least one such feature.

[0032] Example 1

[0033] Reference Figure 1 The present embodiment discloses a road drainage structure that can be used in industrial parks and residential areas, including a road body 1, wherein the upper surface of the road body 1 has a motor vehicle lane 101 and a sidewalk 102 higher than the motor vehicle lane 101, and a curbstone 8 is provided between the motor vehicle lane 101 and the sidewalk 102. The road body 1 is characterized in that a first drainage ditch 11, a second drainage ditch 12 and a water trough 13 are provided inside the road body 1, the head end of the water trough 13 is connected to the first drainage ditch 11, and the end of the water trough 13 is connected to the second drainage ditch 12. The upper parts of the first drainage ditch 11 and the second drainage ditch are The apparatus has multiple openings. A grille 2 having grille holes 21 is provided at the opening of the first drainage ditch 11. The grille 2 has grille holes 21. The grille is located at the edge of the motor vehicle lane 101 near the curb 8. A manhole cover 3 is provided at the opening of the second drainage ditch 12. The manhole cover 3 has multiple first water filter holes 31. A filter plate 4 is provided at the end of the water trough 13 or inside the water trough 13. The filter plate 4 has multiple second water filter holes 41. The sizes of the first and second water filter holes 31, 41 (i.e., the cross-sectional area of the two water filter holes) are both smaller than the size of the grille holes 21 (i.e., the cross-sectional area of the grille holes 21). The first and second water filter holes 31, 41 are generally circular holes, but can also be provided as other hole shapes such as square holes. The first water filter holes 31 are arranged in an array on the manhole cover 3, and the second water filter holes 41 are also arranged in an array on the filter plate 4. The grille holes 21 are generally long square holes. The sizes of the grille holes 21 can be 24*100mm, 20*100mm, etc. Correspondingly, the apertures of the first water filter holes 31 and the second water filter holes 41 can be set to 10mm, 8mm, 6mm, etc.

[0034] A water collecting trough 103 is provided on one edge of the sidewalk 102 near the curbstone 8. The upper surface of the curbstone 8 is higher than the bottom surface of the water collecting trough 103. A plurality of water guiding notches 81 are provided at intervals on the upper surface of the curbstone 8. The bottom surface of the water guiding notches 81 is lower than the bottom surface of the water collecting trough 103 or the bottom surfaces of the two are at the same height. Each water guiding notch 81 corresponds to a grille 2, and the outlet of the water guiding notch 81 is located above the corresponding grille 2.

[0035] The manhole cover 3 is generally located in the middle of the motor vehicle lane 101 , or at the edge of the motor vehicle lane 101 away from the curb 8 .

[0036] The sidewalk 102 can be a cement base with an asphalt pavement, and the fine grooves on the asphalt pavement can improve drainage efficiency. The curbstone 8 can be a reinforced concrete structure or a natural stone such as marble or granite.

[0037] The motor vehicle lane 101 is generally a two-way two-lane or two-way four-lane road with an overall width of about 7-30 meters; it is an asphalt or cement pavement, the width of the sidewalk 102 is generally 1-3 meters, and the width of the sump 103 is generally 70-150 mm and the depth is generally 20-30 mm.

[0038] The first drainage ditch 11 and the second drainage ditch 12 are parallel to each other, and both can independently discharge rainwater into the municipal drainage system and eventually into water bodies such as rivers and oceans. The drainage principle of this drainage structure is as follows: under normal circumstances, rainwater on the sidewalk 102 will first be collected in the sump 103; then, the rainwater in the sump 103 will flow to the location of each grille through the water-guiding notch 81 on the curb 8, and then directly pass through the grille 2 and fall into the first drainage ditch 11, preventing the rainwater from flowing to other locations of the motor vehicle lane 101 and causing a large amount of water accumulation on the motor vehicle lane 101. The rainwater on the motor vehicle lane 101 mainly falls into the first drainage ditch 11 through the grille 2, and can also fall into the second drainage ditch 12 through the first water filter hole 31 on the manhole cover 3. Since the pores of the grille 2 on the first drainage ditch 11 are relatively large, it can play the same drainage role as a conventional drainage ditch. When the rainfall intensity is high, such as during heavy rain or rainstorms, some of the rainwater in the first drain ditch 11 can flow through the gutter 13 into the second drain ditch 12. At this time, the two drains drain water together, which helps improve drainage efficiency. Due to the filtering effect of the manhole cover 3 and the filter plate 4, the rate of silt accumulation in the second drain ditch 12 is much lower than that in the first drain ditch 11. When the rainfall is extremely heavy, the manhole cover 3 on the second drain ditch 12 can be opened. At this time, the second drain ditch 12 with less silt can serve as the main drainage force, further improving drainage efficiency. In addition, during the desilting construction in the first drain ditch 11, the second drain ditch 12 can play a normal drainage role and will not cause drainage efficiency to be insufficient due to construction.

[0039] Example 2

[0040] Figures 2 to 7 Embodiment 2 of this embodiment is disclosed. This embodiment has a similar structure to Embodiment 1, but differs from it in the following two points:

[0041] Difference 1: In this embodiment, a plurality of transverse water channels 104 are spaced apart on the sidewalk 102. The ends of all transverse water channels 104 are connected to the water collection trough 103, and each transverse water channel 104 is perpendicular to the water collection trough 103. The width of each transverse water channel 104 is smaller than that of the water collection trough 103. The provision of transverse water channels 104 can further improve drainage efficiency on the sidewalk 102.

[0042] Difference 2: Based on Example 1, this embodiment adds a filter residue removal device capable of removing filter residue on the filter plate 4.

[0043] In this embodiment, the filter plate 4 is located at the port at the head end of the water channel 13 and is inclined toward the side where the first drainage ditch 11 is located. The angle between the filter plate 4 and the horizontal plane can be 55 degrees, 60 degrees, 70 degrees, etc.

[0044] In a preferred embodiment of the present invention, a filter plate frame 51 is fixed at the port at the head end of the water trough 13, the lower end of the filter plate 4 is hinged to the filter plate frame 51, and the filter plate 4 is connected to the first elastic member 52. The elastic force exerted by the first elastic member 52 on the filter plate 4 makes the upper end of the filter plate 4 abut against the inner wall of the first drainage ditch 11. A vertical hole 14 is provided between the top wall of the water trough 13 and the upper surface of the road body 1. An embedded pipe 16 is fixed in the vertical hole 14. The filter residue removal device includes a top pressure plate 61 and a movable push rod 62, and the head end of the top pressure plate 61 is connected to the embedded pipe 1 6 or the road body 1 is hinged, and the movable push rod 62 is installed on the embedded tube 16 so as to be movable up and down. The upper end of the movable push rod 62 is higher than the upper surface of the road body 1. A second elastic member 63 is provided in the embedded tube 16, which can drive the movable push rod 62 to reset upward after the movable push rod 62 is pressed down. A transmission structure is provided between the movable push rod 62 and the top pressure plate 61. When the movable push rod 62 moves downward, the top pressure plate 61 rotates forward. When the top pressure plate 61 rotates forward, its end presses the filter plate 4 to separate the upper end of the filter plate 4 from the inner wall of the first drainage ditch 11.

[0045] In the above scheme, the transmission structure includes a first rotating block 64 hinged within the embedded tube 16 and located below the movable push rod 62, a first connecting rod 65 connected between the movable push rod 62 and the first rotating block 64, and a second connecting rod 66 connected between the first rotating block 64 and the top pressure plate 61. The first connecting rod 65 is hinged to the movable push rod 62, the first connecting rod 65 is hinged to the first rotating block 64, and the second connecting rod 66 is hinged to the first rotating block 64. The lower end of the second connecting rod 66 is hinged to the middle of the top pressure plate 61, which serves to amplify the stroke. A horizontal plate 67 is fixed within the embedded tube 16. The horizontal plate 67 is provided with a guide hole 671. The movable push rod 62 extends through the guide hole 671 and slidably engages with the horizontal plate 67. The movable push rod 62 is provided with a limit plate 621 located above the horizontal plate 67. The second elastic member 63 is a compression spring disposed between the horizontal plate 67 and the limit plate 621. A spring mounting slot 511 is provided at the top of the filter plate frame 51. The first elastic member 52 is a compression spring disposed in the spring mounting slot 511, with the end of the compression spring abutting against the filter plate 4. To further enhance the smoothness of the up-and-down movement of the movable push rod 62, the guide holes in the cross plate 67 can be replaced with guide sleeve mounting holes, into which linear bearings guiding the movable push rod 62 are mounted.

[0046] In the above solution, the lower end of the filter plate 4 is higher than the bottom of the first drain ditch 11. The working principle of cleaning the filter residue on the filter plate 4 is as follows: when a car passes the area above the movable push rod 62, it will press the movable push rod 62 downward, at which time the second elastic member 63 is compressed. Then, during the downward movement of the first push rod, the first rotating block 64 is driven to rotate through the first connecting rod 65, and then the top pressure plate 61 is driven to rotate downward counterclockwise through the second connecting rod 66. Figure 3 and Figure 5 When the top pressure plate 61 rotates downward, it squeezes the filter plate 4, causing it to rotate counterclockwise to the open position. At this point, the first elastic member 52 is compressed. After the car passes, the movable push rod 62 returns upward under the elastic force of the second elastic member 63, driving the top pressure plate 61 to rotate upward clockwise to the reset position. Next, under the elastic force of the first elastic member 52, the filter plate 4 rotates clockwise to the reset position. During this process, the upper end of the filter plate 4 impacts the inner wall of the first drain ditch 11, shaking the filter residue off the filter plate 4 to the bottom of the first drain ditch 11, thereby achieving a cleaning effect. The filter plate 4 is preferably made of a high-strength material such as fiberglass or alloy steel to withstand impact forces for a long time.

[0047] In the above solution, the elastic coefficient of the second elastic member 63 is greater than that of the first elastic member 52, generally designed to be 3-10 times that of the first elastic member 52. This allows the movable push rod 62, first connecting rod 65, second connecting rod 66, first rotating block 64, and top pressure plate 61 to be reset primarily by the elastic force of the second elastic member 63. Furthermore, the reset speed of the top pressure plate 61 is greater than that of the filter plate 4. When the upper end of the filter plate 4 strikes the inner wall of the first drainage ditch 11, it encounters little resistance from the top pressure plate 61. This solution also has the following advantages: Because the first elastic member 52 is used only to reset the filter plate 4, it is easy to conduct experiments and select a compression spring with an appropriate elastic coefficient as the first elastic member 52 during the early stages of construction verification. In addition, when the movable push rod 62 is pressed down by the car, the elastic resistance of the second elastic member 63 can limit the speed of the top pressure plate 61. When the top pressure plate 61 presses onto the filter plate 4, the first elastic member 52 can also play a buffering role and absorb part of the impact force.

[0048] In some schemes of this embodiment, the above-mentioned transmission structure can also adopt other structural forms, such as omitting the second connecting rod 66 and the first rotating block 64, lengthening the first connecting rod 65, and directly hinged the lower end of the first connecting rod 65 to the middle part of the top pressure plate 61.

[0049] Furthermore, a cover plate 68 is provided at the upper end of the embedded tube 16. This cover plate 68 has a perforation that blocks access to the movable push rod 62. A flexible cover 69 is provided on the upper surface of the cover plate 68 to conceal the perforation and the upper end of the movable push rod 62. The flexible cover 69 is made of materials such as high-strength rubber or high-strength nylon cloth. It can be elastic or a plastically deformable high-strength cloth. Combined with the cover plate 68, it prevents external dust, sand, gravel, and garbage from entering the vertical hole 14. When the movable push rod 62 is raised, its upper end supports the middle portion of the lower surface of the flexible cover. The highest point of the flexible cover protrudes above the upper surface of the road surface, for example, 2-3 cm above the road surface. When the movable push rod 62 is depressed, the upper surface of the flexible cover is flush with the road surface. For roads with few vehicles, the top pressure plate 61 can also be driven by a worker stepping on the upper end of the movable push rod 62. In this case, the second elastic member 63 should be a compression spring with a lower elastic coefficient.

[0050] Example 3

[0051] Figures 8 to 12 Example 3 of this embodiment is disclosed. This embodiment has a similar structure to Example 2, but the difference is that the filter residue removal device in this embodiment is more complex and has more functions than the filter residue removal device in Example 2.

[0052] In this embodiment, in addition to the structure disclosed in Example 2, the filter residue removal device further includes a filter residue brush mechanism. The filter residue brush mechanism includes a frame 71 fixed in the first drain ditch 11, a cleaning frame 72 mounted on the frame 71, a cleaning brush 73 disposed on the cleaning frame 72, and a residue removal power device capable of driving the cleaning brush 73 to reciprocate to clean the filter plate 4.

[0053] The bristles of the cleaning brush 73 are preferably wire, with the free ends of the bristles abutting the side of the filter plate 4 facing the first drain ditch 11. The slag removal power unit can utilize a motor 741 as its power source. The output end of the motor can be connected to a pulley-belt structure or a chain-sprocket mechanism. The cleaning brush 73 is mounted on a corresponding belt 742 or chain. The motor 741 is controlled to rotate forward and reverse to drive the cleaning brush 73 in a reciprocating motion. Generally, only a few to a dozen passes are required to clean the filter plate 4. Alternatively, the slag removal power unit can utilize an electric cylinder as its power source to drive the reciprocating motion of the cleaning brush 73.

[0054] The cleaning rack 72 is movably arranged on the frame 71 , and the frame 71 is provided with a retractable power device capable of driving the cleaning rack 72 to move upward to a retracted state.

[0055] As a further optimization scheme of the above scheme, a sliding frame 75 and a guide structure parallel to the filter plate 4 are provided on the frame 71. The retraction and extension power device includes a retraction and extension driver 76 capable of driving the sliding frame 75 to slide along the guide structure. The sliding frame 75 is connected to the cleaning frame 72 by a plurality of third connecting rods 77. A guide chute 711 and a guide column 712 are provided on the frame 71. The guide column 712 has a guide surface 7121 parallel to the guide structure. The guide chute 711 and the guide surface 7121 form an acute angle. The cleaning frame 72 is provided with a roller 78 located at the lower end of the guide chute 711.

[0056] Preferably, the third connecting rods 77 are arranged in two rows, with each row comprising two or three third connecting rods 77. The distance between the two hinge points on all third connecting rods 77 is substantially the same, and all third connecting rods 77 are parallel. When the rollers 78 on the cleaning frame 72 are positioned at the lower end of the guide chute 711, the bristles of the cleaning brush 73 abut against a side surface of the filter plate 4. At this point, the cleaning brush 73 is driven back and forth by the slag removal power unit to remove the filter residue from the filter plate 4. The retractable actuator 76 is preferably an electric cylinder. When the cleaning frame 72 needs to be retracted, the retractable actuator 76 drives the sliding frame 75 to slide upward along the guide structure. The rollers 78 on the cleaning frame 72 then move upward along the guide chute 711, exit the upper end of the guide chute 711, and then move upward along the guide surface 7121, ultimately moving the cleaning frame 72 to the retracted position. When the cleaning frame 72 is retracted, it facilitates cleaning and replacement of the cleaning brush 73 and facilitates cleaning of the filter plate frame 51.

[0057] This road drainage structure is generally used for roads in industrial parks and residential areas. For some municipal roads with high drainage requirements, the drainage structures therein can also be designed with reference to this road drainage structure.
