[0001] This invention relates to the technical field of permeable asphalt, and in particular to a permeable asphalt road drainage device and drainage method thereof. Background Technology

[0002] Currently, drainage asphalt pavement uses large-pore asphalt mixture as the surface layer, allowing rainfall to penetrate into the drainage functional layer and draining the rainwater, thereby eliminating many factors that cause inconvenience to driving and significantly improving the safety of driving in rainy weather.

[0003] The prior art can be referenced in Chinese Patent No. CN206956494U, which discloses a permeable asphalt road drainage device, including a permeable asphalt layer, a permeable layer, a waterproof bonding layer, and a road base. The permeable asphalt layer is laid with permeable asphalt mixture, with a porosity of 18-22% and a thickness of 3-5 cm. The permeable layer is laid with crushed stone with a particle size of 15-20 mm. Drainage boxes are set on both sides of the bottom end of the permeable layer. The drainage boxes are laid along the extension direction of the road surface. One lateral end face of the drainage box is connected to the curb stones set on both sides of the road surface. The drainage box is a cavity, and the curvature of its upper and lower end faces is consistent with the road surface. Multiple through holes are set on the upper end face and the end face connected to the curb stone.

[0004] However, when dust or debris falls onto the permeable asphalt layer, it can cause blockage, thereby reducing the permeability of the permeable asphalt layer. Summary of the Invention

[0005] In order to improve the permeability efficiency of permeable asphalt layers, this application provides a permeable asphalt road drainage device, which adopts the following technical solution:

[0006] A permeable asphalt road drainage device includes a permeable asphalt layer, a permeable layer at the bottom of the permeable asphalt layer, a first conveying pipe inside the permeable layer, a plurality of second conveying pipes connected to the first conveying pipe, a plurality of third conveying pipes connected to the second conveying pipes, the third conveying pipes being connected to the permeable asphalt layer, a piston chamber being formed inside the permeable layer, the piston chamber being connected to the first conveying pipe, a piston plate being slidably disposed inside the piston chamber, the piston plate cooperating with the side wall of the piston chamber, and a drive mechanism for driving the piston plate to compress air being disposed inside the piston chamber.

[0007] By adopting the above technical solution, when dust or debris in the air falls into the gaps in the permeable asphalt layer, the piston plate is driven by the drive mechanism to move and compress the air. The air enters the first conveying pipe from the piston chamber in sequence, and then is conveyed from the first conveying pipe to multiple second conveying pipes. The air is then conveyed from the second conveying pipes to multiple third conveying pipes, and finally the air is compressed from the third conveying pipes into the gaps in the permeable asphalt layer. This makes it easier to impact the debris in the gaps in the permeable asphalt layer to the outside, thereby improving the permeability efficiency of the permeable asphalt layer.

[0008] Preferably, the driving mechanism includes a plurality of first springs, one end of the first spring is fixedly connected to the piston plate, the other end of the first spring is fixedly connected to the inner wall of the piston chamber, and the piston chamber is provided with a driving assembly for driving the piston plate to move toward the first spring.

[0009] By adopting the above technical solution, when it is necessary to drive the piston plate to move and compress air, the piston plate is first driven to move towards the first spring by the drive assembly. At this time, the first spring is in a compressed state. When the drive assembly is removed from driving the piston plate to move towards the first spring, the piston plate can be easily driven to move and compress air under the elastic force of the first spring.

[0010] Preferably, the driving assembly includes a driving rod fixedly connected to the piston plate, a rack on the driving rod, a rotating shaft rotatably mounted on the inner wall of the piston chamber, a gear driven on the rotating shaft, the gear engaging with the rack, a ratchet driven on the rotating shaft, a pawl on the inner wall of the piston chamber engaging with the ratchet, a rotating component for driving the gear to rotate on the permeable layer, and a separating component for driving the rack to separate from the gear on the driving rod.

When it is necessary to cancel the driving effect of the driving component on the gear, the gear and rack can be separated by the separating component.

The drive plate drives the first inclined block to rotate. When the first inclined block abuts against the gear, the first inclined block drives the gear to rotate. At this time, under the reset action of the reset component on the drive plate, the drive plate rotates in the opposite direction. At this time, the first inclined block abuts against the gear. Under the cooperation of the first inclined surface and the gear, the first inclined block moves away from the gear, which makes it easier for the drive plate to rotate to the initial position. Repeating the above steps makes it easier to drive the gear to rotate.

[0014] Preferably, the rotating component includes a linkage block, a second sliding groove is formed on the permeable asphalt layer, the linkage block is slidably disposed on the inner wall of the second sliding groove, the second sliding groove is connected to the linkage groove, a linkage rod is fixedly connected to the linkage block, and the linkage rod can cooperate with the drive plate; a plurality of third springs are disposed in the second sliding groove, one end of the third spring is fixedly connected to the linkage block, and the other end of the third spring is fixedly connected to the inner wall of the second sliding groove.

[0015] By adopting the above technical solution, when a vehicle passes over the permeable asphalt layer, the vehicle crushes the linkage block and drives the linkage block to move downward in the vertical direction. The linkage block drives the linkage rod to move downward in the vertical direction, and the linkage rod abuts against the drive plate, which facilitates the rotation of the drive plate.

[0019] By adopting the above technical solution, when it is necessary to drive the rack and gear to separate, the second inclined block is first driven to move by the driving component, the second inclined block drives the connecting block to move, and the connecting block drives the rack to move, which facilitates the separation of the rack and gear. At this time, the fifth spring is in a compressed state. When the driving component stops driving the second inclined block to move, the rack is reset under the elastic force of the fifth spring.

[0021] By adopting the above technical solution, when it is necessary to drive the second inclined block to move, the drive rod is first driven to move downward in the vertical direction by the drive assembly, and the drive rod drives the abutment block to move downward in the vertical direction. When the abutment block abuts against the inner wall of the piston chamber, the abutment block moves upward in the vertical direction relative to the second inclined block. At this time, under the cooperation of the second inclined surface and the abutment block, it is convenient to drive the second inclined block to move.

[0022] This application provides a drainage method for a permeable asphalt road drainage device, which adopts the following technical solution:

[0023] S1: When a vehicle passes over the permeable asphalt layer, the vehicle crushes the linkage block and drives the linkage block to move downward in the vertical direction. The linkage block drives the linkage rod to move, and the linkage rod drives the drive plate to rotate.

[0026] S4: The first delivery pipe delivers air to multiple second delivery pipes, which then deliver the air to multiple third delivery pipes. Finally, the air is compressed from the third delivery pipes into the gaps in the permeable asphalt layer, which facilitates the impact of debris in the gaps of the permeable asphalt layer to the outside.

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

[0028] 1. When dust or debris in the air falls into the gaps in the permeable asphalt layer, the piston plate is driven by the drive mechanism to move and compress the air. The air enters the first conveying pipe from the piston chamber in sequence, and then is conveyed from the first conveying pipe to multiple second conveying pipes. The air is then conveyed from the second conveying pipes to multiple third conveying pipes, and finally the air is compressed from the third conveying pipes into the gaps in the permeable asphalt layer. This makes it easier to impact the debris in the gaps in the permeable asphalt layer to the outside, thereby improving the permeability efficiency of the permeable asphalt layer.

[0029] 2. When it is necessary to drive the piston plate to move closer to the first spring, the rotating component drives the gear to rotate in the forward direction, and the gear drives the rack to move, which facilitates the movement of the piston plate closer to the first spring; at the same time, the ratchet and pawl can prevent the gear from rotating in the reverse direction. When it is necessary to cancel the driving effect of the drive component on the gear, the gear and rack can be separated by the separation component.

[0030] 3. When the drive gear needs to rotate, the drive plate is first driven to rotate forward by the rotating component. The drive plate drives the first inclined block to rotate. When the first inclined block abuts against the gear, the first inclined block drives the gear to rotate. At this time, under the reset action of the reset component, the drive plate rotates in the opposite direction. At this time, the first inclined block abuts against the gear. Under the cooperation of the first inclined surface and the gear, the first inclined block moves away from the gear, which makes it easier for the drive plate to rotate to the initial position. Repeating the above steps makes it easier to drive the gear to rotate. Attached Figure Description

Detailed Implementation

[0037] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0038] This invention discloses a permeable asphalt road drainage device, such as... Figure 1 and Figure 2As shown, the system includes a permeable asphalt layer 1 with a square cross-section. A permeable layer 11 with a square cross-section is located at the bottom of the permeable asphalt layer 1. A first conveying pipe 12 is installed within the permeable layer 11, extending along the width of the permeable asphalt layer 1. Multiple second conveying pipes 13 are connected to the first conveying pipe 12, extending along the length of the permeable asphalt layer 1. Multiple third conveying pipes 14 are connected to the second conveying pipes 13, extending vertically. The third delivery pipe 14 is connected to the permeable asphalt layer 1. A piston chamber 15 is provided in the permeable layer 11. The piston chamber 15 has a square cross-section and extends vertically. The piston chamber 15 is connected to the first delivery pipe 12. A piston plate 16 is provided in the piston chamber 15. The piston plate 16 has a square cross-section and slides vertically on the inner wall of the piston chamber 15. The piston plate 16 cooperates with the side wall of the piston chamber 15. A drive mechanism 2 for driving the piston plate 16 to compress air is provided in the piston chamber 15.

[0039] When dust or debris in the air falls into the gaps in the permeable asphalt layer 1, the piston plate 16 is driven by the drive mechanism 2 to move and compress the air. The air enters the first conveying pipe 12 from the piston chamber 15, and then is conveyed from the first conveying pipe 12 to multiple second conveying pipes 13. The second conveying pipes 13 then convey the air to multiple third conveying pipes 14, and finally the air is compressed from the third conveying pipes 14 into the gaps in the permeable asphalt layer 1. This facilitates the impact of debris in the gaps in the permeable asphalt layer 1 to the outside, thereby improving the permeability efficiency of the permeable asphalt layer 1.

[0040] like Figure 2 As shown, the drive mechanism 2 includes four first springs 211, which are arranged vertically. One end of each first spring 211 is fixedly connected to the bottom of the piston plate 16, and the other end is fixedly connected to the inner wall of the piston chamber 15. A drive assembly 22 is provided inside the piston chamber 15 to drive the piston plate 16 towards the first springs 211. When it is necessary to drive the piston plate 16 to move and compress air, the drive assembly 22 first drives the piston plate 16 towards the first springs 211, at which point the first springs 211 are compressed. When the drive assembly 22 is removed from driving the piston plate 16 towards the first springs 211, the elastic force of the first springs 211 facilitates the movement of the piston plate 16 and the compression of air.

[0041] like Figure 2 , Figure 3 and Figure 4As shown, the drive assembly 22 includes a drive rod 221 with a square cross-section. The drive rod 221 is fixedly connected to the bottom of the piston plate 16. A rack 222 is provided on the drive rod 221, which is arranged vertically. A rotating shaft 223 is rotatably mounted on the inner wall of the piston chamber 15 via a bearing. The rotating shaft 223 has a circular cross-section and is arranged along the width direction of the permeable asphalt layer 1. A gear 224 is driven and connected to the rotating shaft 223, and the gear 224 is sleeved and fixed to the rotating shaft 223. On the outer wall of shaft 223, gear 224 can engage with rack 222. A ratchet 225 is connected to the rotating shaft 223 for transmission. The ratchet 225 is sleeved and fixed on the outer wall of the rotating shaft 223. A pawl 226 is rotatably provided on the inner wall of piston chamber 15. The pawl 226 can engage with ratchet 225. A rotating component 23 for driving gear 224 to rotate is provided on permeable layer 11. A separating component 24 for driving rack 222 to separate from gear 224 is provided on drive rod 221.

[0042] When it is necessary to drive the piston plate 16 to move closer to the first spring 211, the rotating component 23 drives the gear 224 to rotate in the forward direction, and the gear 224 drives the rack 222 to move, thereby facilitating the movement of the piston plate 16 closer to the first spring 211. At the same time, the ratchet 225 and the pawl 226 can prevent the gear 224 from rotating in the reverse direction. When it is necessary to cancel the driving effect of the driving component 22 on the gear 224, the separation component 24 can be used to drive the gear 224 to separate from the rack 222.

[0043] like Figure 2 and Figure 3 As shown, the rotating component 23 includes a drive plate 231, which is square in shape. A linkage groove 232 is provided on one inner wall of the piston chamber 15. The linkage groove 232 has a square cross-section and extends vertically. The drive plate 231 is rotatably mounted on the inner wall of the linkage groove 232 via a bearing. A first sliding groove 233 is provided on the side of the drive plate 231 near the gear 224. The first sliding groove 233 has a square cross-section and extends along the length of the drive plate 231. A first inclined block 234 is provided on the inner wall of the first sliding groove 233. The first inclined block 234 is slidably mounted on the inner wall of the first sliding groove 233 along the length of the drive plate 231.

[0044] like Figure 2 , Figure 3 and Figure 5As shown, a first inclined surface 235 is provided on the side of the first inclined block 234 near the gear 224. The first inclined surface 235 can cooperate with the gear 224, and the first inclined block 234 can cooperate with the gear 224. A second spring 236 is provided in the first sliding groove 233. The second spring 236 is arranged along the length direction of the drive plate 231. One end of the second spring 236 is fixedly connected to the first inclined block 234, and the other end of the second spring 236 is fixedly connected to the inner wall of the first sliding groove 233. A rotating component 25 for driving the drive plate 231 to rotate is provided on the permeable asphalt layer 1, and a resetting component 26 for driving the drive plate 231 to reset is provided in the linkage groove 232.

[0045] When it is necessary to drive the gear 224 to rotate, the drive plate 231 is first driven to rotate in the forward direction by the rotating member 25. The drive plate 231 drives the first inclined block 234 to rotate. When the first inclined block 234 abuts against the gear 224, the first inclined block 234 drives the gear 224 to rotate. At this time, under the reset action of the reset member 26 on the drive plate 231, the drive plate 231 rotates in the reverse direction. At this time, the first inclined block 234 abuts against the gear 224. Under the cooperation of the first inclined surface 235 and the gear 224, the first inclined block 234 moves away from the gear 224, so that the drive plate 231 can rotate to the initial position. Repeat the above steps to facilitate the rotation of the gear 224.

[0046] like Figure 2 and Figure 4 As shown, the rotating component 25 includes a linkage block 251 with a square cross-section. A second sliding groove 252 is provided on the permeable asphalt layer 1. The second sliding groove 252 has a square cross-section and extends vertically. The linkage block 251 is slidably disposed on the inner wall of the second sliding groove 252 in the vertical direction. The second sliding groove 252 is connected to the linkage groove 232. A linkage rod 253 is fixedly connected to the bottom of the linkage block 251. The linkage rod 253 has a circular cross-section and is arranged vertically. The bottom end of the linkage rod 253 can cooperate with the top of the drive plate 231. A plurality of third springs 254 are provided in the second sliding groove 252. The third springs 254 are arranged vertically. One end of the third spring 254 is fixedly connected to the linkage block 251, and the other end of the third spring 254 is fixedly connected to the inner wall of the second sliding groove 252.

[0047] When a vehicle passes over the permeable asphalt layer 1, the vehicle crushes the linkage block 251 and drives the linkage block 251 to move downward in the vertical direction. The linkage block 251 drives the linkage rod 253 to move downward in the vertical direction. The linkage rod 253 abuts against the drive plate 231, which facilitates the rotation of the drive plate 231. The third spring 254 is in a compressed state. After the vehicle passes, the linkage block 251 moves upward in the vertical direction under the elastic force of the third spring 254, which facilitates the reset of the linkage block 251.

[0048] like Figure 2 and Figure 4 As shown, the reset component 26 includes a fourth spring 261, which is arranged vertically. One end of the fourth spring 261 is fixedly connected to the bottom of the drive plate 231, and the other end is fixedly connected to the inner wall of the linkage groove 232. When it is necessary to drive the drive plate 231 to reset, the fourth spring 261 facilitates the reset under its elastic force.

[0049] like Figure 5 As shown, the separating component 24 includes multiple fifth springs 241. The fifth springs 241 are arranged along the length direction of the drive rod 221. A mounting groove 242 is provided on the side wall of the drive rod 221 near the gear 224. The mounting groove 242 has a square cross-section and extends along the length direction of the drive rod 221. The rack 222 is slidably disposed on the inner wall of the mounting groove 242 along the length direction of the drive rod 221. One end of the fifth spring 241 is fixedly connected to the side of the rack 222 away from the gear 224, and the other end of the fifth spring 241 is fixedly connected to the inner wall of the mounting groove 242. A connecting block 243 is fixedly connected to one side of the rack 222. The connecting block 243 is square. A second inclined block 244 is fixedly connected to the connecting block 243. The second inclined block 244 has a square cross-section. A driving member 27 for driving the second inclined block 244 to move along the length direction of the drive rod 221 is provided on the drive rod 221.

[0050] When it is necessary to drive the rack 222 to separate from the gear 224, the second inclined block 244 is first driven to move by the driving member 27. The second inclined block 244 drives the connecting block 243 to move, and the connecting block 243 drives the rack 222 to move, thereby facilitating the separation of the rack 222 from the gear 224. At this time, the fifth spring 241 is in a compressed state. When the driving member 27 stops driving the second inclined block 244 to move, the rack 222 is reset under the elastic force of the fifth spring 241.

[0051] like Figure 2 and 5As shown, the driving component 27 includes an abutment block 271, which is square in shape. A through hole 272 is provided at the bottom of the driving rod 221. The through hole 272 has a square cross-section and extends vertically. The through hole 272 communicates with the mounting groove 242. The abutment block 271 is slidably disposed on the inner wall of the through hole 272 in the vertical direction. A second inclined surface 273 is provided on the side of the second inclined block 244 near the abutment block 271, and the abutment block 271 can cooperate with the second inclined surface 273. The side wall of the through hole 272 is provided with... A reset groove 274 is provided, the cross-section of which is square and extends vertically. A reset plate 275 is slidably disposed in the reset groove 274 along the vertical direction. The reset plate 275 is square and is fixedly connected to one side of the abutment block 271. A sixth spring 276 is provided in the reset groove 274. The sixth spring 276 is disposed vertically, one end of which is fixedly connected to the inner wall of the reset groove 274, and the other end of which is fixedly connected to the reset plate 275.

[0052] When it is necessary to drive the second inclined block 244 to move, the drive rod 221 is first driven to move downward in the vertical direction by the drive assembly 22. The drive rod 221 drives the abutment block 271 to move downward in the vertical direction. When the abutment block 271 abuts against the inner wall of the piston chamber 15, the abutment block 271 moves upward in the vertical direction relative to the second inclined block 244. At this time, under the cooperation of the second inclined surface 273 and the abutment block 271, it is easy to drive the second inclined block 244 to move.

[0053] This invention also discloses a drainage method for a permeable asphalt road drainage device, comprising the following steps:

[0054] S1: When a vehicle passes over the permeable asphalt layer 1, the vehicle crushes the linkage block 251 and drives the linkage block 251 to move downward in the vertical direction. The linkage block 251 drives the linkage rod 253 to move, and the linkage rod 253 drives the drive plate 231 to rotate.

[0055] S2: The drive plate 231 drives the gear 224 to rotate, the gear 224 drives the rack 222 to move, the rack 222 drives the drive rod 221 to move downward in the vertical direction, and the drive rod 221 drives the piston plate 16 to move downward in the vertical direction. At this time, the first spring 211 is in a compressed state.

[0056] S3: When the drive rod 221 drives the abutment block 271 to abut against the inner wall of the piston chamber 15, the abutment block 271 drives the second inclined block 244 to move, the second inclined block 244 drives the rack 222 to move, and when the rack 222 separates from the gear 224, the drive rod 221 moves upward in the vertical direction under the elastic force of the first spring 211 and compresses air into the first delivery pipe 12;

[0057] S4: The first delivery pipe 12 delivers air to multiple second delivery pipes 13, and then the second delivery pipes 13 deliver air to multiple third delivery pipes 14, and finally compresses the air from the third delivery pipes 14 into the gaps of the permeable asphalt layer 1, thereby facilitating the impact of debris in the gaps of the permeable asphalt layer 1 to the outside.
