Description

Technical Field

[0001] The present invention relates to the technical field of permeable pavement technology, and in particular to an anti-blocking permeable pavement structure and a method for detecting its anti-blocking effect. Background Art

[0002] As a new type of environmentally friendly and ecological road material, permeable pavement has the property of water permeability. When it rains, it can quickly eliminate the ponding on roads and squares, and has been widely used in urban roads, squares, parking lots and other places. However, in the actual use process, the water seepage holes of the existing permeable pavement are easily blocked by sundries, resulting in a significant decline in the water permeability performance and seriously affecting the drainage effect. At present, although a filter plate can be used to intercept sundries, the filter plate itself will still be blocked after long-term use, and it needs to rely on manual cleaning or high-pressure water flushing for maintenance regularly. This not only has a large operation difficulty, but also has a high maintenance cost and low efficiency. Summary of the Invention

[0003] In view of the above-mentioned defects existing in the prior art, the present invention provides an anti-blocking permeable pavement structure and a method for detecting its anti-blocking effect to solve the problems of easy blockage and high maintenance cost of the permeable pavement.

During use, not only can sundries be prevented from entering the water seepage holes and causing blockage of the water seepage holes, but also the sundries accumulated on the filtering component can be timely discharged through the collection hopper, the first slag discharge channel and the second slag discharge channel, so as not to affect the normal use of the filtering component, greatly reducing the manual maintenance frequency and lowering the maintenance cost.

[0012] Optionally, a plurality of slide grooves are provided on the inclined surface of the connecting block, and the number of the telescopic members matches the number of the slide grooves.

[0013] Optionally, a plurality of the first filter plates are provided, and the number of the collecting buckets matches the number of the first filter plates.

[0014] Optionally, a plurality of contact blocks are provided, and the number and position of the toggle rods are adapted to the multiple contact positions.

[0015] Optionally, the first filter plate is disposed at a chamfered angle close to another side of the fixing frame.

[0016] Optionally, the rotating shaft is provided with a transmission tooth, and the first telescopic column is provided with a transmission groove meshing with the transmission tooth.

[0017] Optionally, the filter assembly further includes: a second filter plate, movably arranged below the first filter plate; and a dredging assembly, arranged below the second filter plate; wherein the second filter plate is connected to the second telescopic column and can move synchronously with the second telescopic column, and the second filter plate can contact the dredging assembly driven by the second telescopic column, so that the dredging assembly dredges the mesh of the second filter plate. By setting the second filter plate, a double filtering protection is formed with the first filter plate, which can further prevent debris from entering the seepage holes and significantly reduce the risk of blockage. With the automatic cleaning of the dredging assembly, the fluidity of the second filter plate can be guaranteed, the long-term stable drainage performance of the road surface can be ensured, and the maintenance frequency can be reduced.

[0018] Optionally, the dredging component includes: a fixing plate, one side of which is connected to the fixing frame and the other side is connected to the inner wall of the water permeable hole; the second filter plate is connected to the second telescopic column through a connecting rod, a baffle is arranged on one side of the second filter plate, the baffle is attached to the fixing frame, one end of the connecting rod is connected to the second telescopic column, and the other end passes through the installation groove and is connected to the baffle. The connecting rod is slidably matched with a sliding groove formed in the installation groove, and a second spring is connected between the connecting rod located in the installation groove and the bottom wall of the installation groove.

[0019] Optionally, a drain pipe is also communicated between the fixing frame and the first slag discharge channel; an inlet and an outlet are arranged on the fixing frame; wherein, the outlet is located at the bottom of the fixing frame, and a buoyancy switch assembly for closing the outlet is arranged on the outlet. When the rainwater depth in the fixing frame exceeds a preset depth, the buoyancy switch assembly is opened so that the rainwater in the fixing frame passes through the outlet and enters the drain pipe.

[0020] Optionally, a guide column is installed at the outlet of the fixing frame. The guide column includes a vertically arranged communication port and a horizontally arranged diversion port which are communicated with each other; the buoyancy switch assembly includes: a fixed seat arranged on one side of the guide column; a sleeve with a closed top and an open bottom covering the guide column; a lever, one end of which is hinged to the fixed seat and the sleeve, and the other end is hinged to a floating ball; wherein, in the initial state, the floating ball approaches the bottom of the fixing frame under the action of gravity so that the sleeve closes the guide column. When the rainwater depth in the fixing frame exceeds the preset depth, the sleeve is released from closing the guide column under the action of the floating ball and the lever.

[0021] When the water permeable holes are filled with rainwater, the rainwater in the water permeable holes can enter the collection hopper to wash the first slag discharge channel and the second slag discharge channel and discharge sundries. At the same time, by adding a drain pipe and realizing the opening and closing control through the floating ball switch assembly, when the water permeable holes are filled with rainwater, it can be quickly discharged into the first and second slag discharge channels through the collection hopper and the drain pipe at the same time, significantly increasing the drainage volume. The increase in water flow increases the water pressure in the slag discharge channel, enhances the impact force on sundries, makes the slag discharge smoother, and effectively prevents the channel from being blocked. At the same time, when the collection hopper is blocked by sundries and the drainage is not smooth, the drain pipe can be used as an alternative drainage path, and the filtered rainwater flow is used to assist in dredging the slag discharge channel to ensure drainage under extreme conditions and greatly reduce the maintenance requirements.

[0022] Optionally, the anti-blocking permeable pavement structure further includes a water absorption component; a water storage cavity is further provided on the pavement body, and the water storage cavity is communicated with the water seepage holes through a channel; the water absorption component includes: a water absorption rod, one end of which is located in the water storage cavity and the other end passes through the pavement body and communicates with the external environment; a water absorption and expansion rubber, which is arranged at the bottom of the water storage cavity; a weight pressing plate, which is connected to the water absorption rod and contacts the upper side of the water absorption and expansion rubber; wherein, the pavement body is provided with a mounting hole for accommodating the water absorption rod. When the water absorption and expansion rubber is not expanded, a receiving groove is formed between the top of the water absorption rod and the mounting hole. After the water absorption and expansion rubber absorbs water and expands, the top of the water absorption rod is flush with the top of the mounting hole. Through the setting of the water storage cavity, rainwater can be stored, the whole can be moistened by the water absorption rod after absorbing water, and the rainwater can be evaporated into the external environment, thereby increasing the humidity near the surface of the pavement and achieving the effect of dust reduction. On sunny days, the receiving groove can play a role in dust collection and storage. After the rainwater absorbed by the water absorption rod evaporates, the dust in the receiving groove agglomerates, avoiding a large amount of dust when people and vehicles pass by. On rainy days, under the push of the top of the water absorption rod, the hardened agglomerated dust can be broken and moved outside the pavement body; after the hardened agglomerated dust is broken, it is not only easier to be washed away by rainwater, but also not easy to block other holes in the pavement.

[0023] Optionally, the second slag discharge channel is arranged in the permeable base layer.

[0024] Optionally, the diameter of the water seepage holes is smaller than the diameter of the permeable holes. The diameter of the water seepage holes is smaller than that of the permeable holes, which can ensure that in case of light rainfall, the rainwater can also fill the permeable holes, so that the rainwater in the permeable holes enters the collection hopper to wash the first slag discharge channel and the second slag discharge channel.

[0025] A method for detecting the anti-blocking effect of an anti-blocking permeable pavement structure includes the following steps:

[0026] Step S1: Detect the penetration speed of the anti-blocking permeable pavement structure in the unblocked state to obtain the initial penetration speed;

[0027] Step S2: Apply the blocking material on the surface of the anti-blocking permeable pavement structure so that the blocking material plugs the upper part of the permeable holes of the anti-blocking permeable pavement;

[0028] Step S3: Dry and solidify the blocking material;

[0029] Step S4: Detect the penetration speed of the anti-blocking permeable pavement structure in the blocked state to obtain the blocked penetration speed;

[0030] Step S5: Repeat Step S2 and Step S3;

[0031] Step S6: Roll a roller on the surface of the anti-blocking permeable pavement in the blocked state;

[0032] During the process of rolling with the roller, the clogging substances in the water permeable holes can be broken;

[0033] Step S7: Simulate rainfall to make rainwater gather on the surface of the anti-clogging water permeable road surface;

[0034] Step S8: Detect the infiltration speed of the anti-clogging water permeable road surface to obtain the dredged infiltration speed;

[0035] Step S9: Compare the initial infiltration speed, the clogged infiltration speed and the dredged infiltration speed to obtain the anti-clogging effect of the anti-clogging water permeable road surface.

[0036] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0037] 1. Through the setting of the driving component, the sundries on the filtering component can be automatically removed, thereby avoiding the blockage of the filter plate and ensuring the long-term smoothness of the water permeable holes. Specifically, during use, when people or vehicles pass by on the road surface, the first telescopic column will move downward, so that the filter plate in the water permeable hole rotates towards the collecting hopper to pour out the sundries or the second telescopic column drives the scraper to scrape and clean the sundries on the first filter plate. The sundries enter the slag discharge channel through the collecting hopper and are discharged centrally, realizing the automatic removal of sundries. This can not only prevent sundries from entering the water seepage holes and causing blockage of the water seepage holes, but also timely discharge the sundries accumulated on the filtering component through the collecting hopper, the first slag discharge channel and the second slag discharge channel, so as not to affect the normal use of the filtering component, greatly reducing the manual maintenance frequency and lowering the maintenance cost.

[0038] 2. Through the transmission mode of the cooperation of the telescopic rod, the spring, the roller and the sliding groove, the movement of the scraper is stable and the cleaning effect is good.

[0039] 3. Through the setting of the second filter plate, a double filtration protection is formed with the first filter plate, which can further prevent sundries from entering the water seepage holes and significantly reduce the blockage risk. With the automatic cleaning of the dredging component, the fluidity of the second filter plate can be guaranteed, ensuring the long-term stable drainage performance of the road surface and reducing the maintenance frequency.

[0040] 4. When the water holes are filled with rainwater, the rainwater in the water holes can enter the collection bucket to flush the first and second slag discharge channels and discharge debris. At the same time, by adding a drainage pipe and realizing the opening and closing control through the float switch assembly, when the rainwater in the water holes is full, it can be quickly discharged into the first and second slag discharge channels through the collection bucket and the drainage pipe at the same time, significantly increasing the drainage volume. The increase in water flow increases the water pressure in the slag discharge channel, enhances the impact force on the debris, makes the slag discharge smoother, and effectively prevents the channel from being blocked. At the same time, when the collection bucket is not drained smoothly due to the accumulation of debris, the drainage pipe can be used as a backup drainage path, and the filtered rainwater flow can be used to assist in dredging the slag discharge channel, ensuring that drainage can still be achieved under extreme conditions, greatly reducing maintenance requirements.

[0041] 5. Rainwater can be stored by setting up the water storage chamber. After the water is absorbed by the water absorption rod, the whole road is moistened and can evaporate the rainwater into the external environment, thereby increasing the humidity near the road surface and achieving the effect of dust reduction. On sunny days, the holding tank can play the role of dust collection and storage. After the rainwater absorbed by the water absorption rod evaporates, the dust in the holding tank will clump, avoiding a large amount of dust when people and vehicles pass by. On rainy days, under the push of the top of the water absorption rod, the hardened clumped dust can be broken and moved outside the road body; after the hardened clumped dust is broken, it is not only easier to be washed away by rainwater, but also not easy to block other holes in the road surface.

[0059] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0060] Example 1

[0061] like Figure 1and Figure 2 As shown, an embodiment of the present invention provides an anti-blocking and water-permeable pavement structure, which includes a pavement body 1, a collecting bucket 2 and a filtering component 3.

[0062] The pavement body 1 is provided with a water-permeable hole 11 and a water-seepage hole 12. The water-permeable hole 11 is located above the water-seepage hole 12, and the two are coaxially arranged and interconnected. After passing through the water-permeable hole 11 and the water-seepage hole 12, rainwater can enter the water-permeable base layer 15 located below the pavement body 1. The filter assembly 3 is arranged in the water-permeable hole 11 to filter large debris in the rainwater to prevent the water-seepage hole 12 from being blocked due to the debris entering the water-seepage hole 12.

[0063] The pavement body 1 is also provided with a first slag discharge channel 13 and a second slag discharge channel 14. The first slag discharge channel 13 has a collecting bucket 2 at the upper end, and the other end extends to the upper part of the second slag discharge channel 14 and is connected thereto. The collecting bucket 2 is provided on the inner wall of the water permeable hole 11, and one end of the collecting bucket 2 extends into the water permeable hole 11 and is located below the outlet end of the filter assembly 3.

[0064] When in use, when rainwater fills up the water-permeable hole 11, the rainwater in the water-permeable hole 11 can enter the collecting bucket 2 to flush the first slag discharge channel 13 and the second slag discharge channel 14 to discharge debris. Optionally, the diameter of the seepage hole 12 is smaller than the diameter of the water-permeable hole 11, so that it can be ensured that when there is a small amount of rainfall, the rainwater can also fill up the water-permeable hole 11, so that the rainwater in the water-permeable hole 11 can enter the collecting bucket 2 to flush the first slag discharge channel 13 and the second slag discharge channel 14 to discharge debris.

[0065] Optionally, the second slag discharge channel 14 is arranged on the permeable base layer 15 .

[0066] Example 2

[0067] The present invention provides an anti-blocking and water-permeable pavement structure. Based on Example 1, Figure 6 and Figure 7 As shown, in this embodiment, the filter assembly 3 adopts a filter plate 31 , the structure of the filter plate 31 is adapted to the water permeable hole 11 , and is movably arranged in the water permeable hole 11 .

[0068] Furthermore, the anti-blocking and permeable pavement structure further includes a driving assembly 4. The driving assembly 4 is arranged above the filter plate 31, and is used to drive the filter plate 31 to be inclined toward the collecting bucket 2, so as to pour the debris on the filter plate 31 into the collecting bucket 2.

[0069] As an implementation scenario, in this scenario, the driving assembly 4 includes a first telescopic column 41 , a first elastic column 42 , a rotating shaft 43 and a toggle rod 44 .

[0070] The first telescopic column 41 is longitudinally movable and arranged in the pavement body 1, and the first elastic column 42 is connected to the bottom of the first telescopic column 41, and is used to extend the upper end of the first telescopic column 41 outside the pavement body 1. One end of the rotating shaft 43 is transmission-connected to the first telescopic column 41, and the other end is rotationally connected to the inner wall of the water-permeable hole 11. The rotating shaft 43 is arranged close to the filter plate 31, and one end of the toggle rod 44 can contact the upper surface of the filter plate 31 and rotate the filter plate 31 toward the collection bucket 2. When the toggle rod 44 rotates away from the filter plate 31 along with the rotating shaft 43, the filter plate 31 can rotate in the reverse direction to reset.

[0071] During use, when a person or vehicle passes by on the pavement body 1, the first telescopic column 41 is pressed and moves downward. After the pressure on the first telescopic column 41 is released, the first telescopic column 41 moves upward and resets under the reset force of the first elastic column 42, so that the upper end of the first telescopic column 41 re-extends outside the pavement body 1. When the first telescopic column 41 is pressed and drives the rotating shaft 43 to rotate, one end of the toggle rod 44 contacts the filter plate 31 and causes the filter plate 31 to rotate toward the collection bucket 2, thereby pouring the debris into the collection bucket 2, and the debris enters the second slag discharge channel 14 after passing through the first slag discharge channel 13, and then is guided to a designated location for collection (such as outside the permeable base layer 15), so as to avoid affecting the normal use of the filter plate 31 due to the accumulation of debris on the filter plate 31. In this embodiment, through the setting of the filter plate 31, when there are too many debris or under the action of the toggle rod 44, the debris accumulated on the filter plate 31 will be poured into the collection bucket 2, which can effectively prevent the seepage hole 12 from being blocked.

[0072] Optionally, the middle portion of the filter plate 31 is rotatably connected to the inner wall of the water permeable hole 11 via a rotating rod.

[0073] Optionally, the rotating shaft 43 is arranged near the left part of the filter plate 31. In the initial state, the weight of the right part of the filter plate 31 is greater than the weight of the left part of the filter plate 31. Specifically, the rotating shaft 43 is arranged horizontally and rotationally at the upper part of the water permeable hole 11, and is connected to the first telescopic column 41 through the rotating shaft 43 to convert the longitudinal movement of the first telescopic column 41 into the rotational movement of the rotating shaft 43 around its own axis, so that when the toggle rod 44 can rotate with the rotating shaft 43, during the rotation process, one end of the toggle rod 44 can contact the filter plate 31, so that the filter plate 31 faces the collection bucket 2 of the first slag discharge channel 13 to pour the debris into the collection bucket 2. As an implementation scenario, illustratively, a transmission tooth can be arranged on the rotating shaft 43, and the first telescopic column 41 has a transmission groove 411 meshing with the transmission tooth; the transmission tooth meshes with the transmission groove 411 to convert the longitudinal movement of the first telescopic column 41 into the rotational movement of the rotating shaft 43 around its own axis. The toggle rod 44 can not only rotate the filter plate 31 downward to pour out the debris, but also play a role in breaking up the plate-crusted objects.

[0074] In one embodiment, the driving assembly 4 further includes a plurality of crushing teeth 45 arranged on the outer wall of the rotating shaft 43. The crushing teeth 45 rotate with the rotating shaft 43. During the rotation, the crushing teeth 45 can crush the caked blockages to dredge the water permeable holes 11, thereby achieving the effect of preventing blockages.

[0075] Embodiment 3

[0076] Since the surface of the filter plate 31 in Embodiment 2 is still prone to adhering to sundries after long-term use, which affects the fluidity of the filter holes.

[0077] On the basis of Embodiment 1, the embodiment of the present invention provides an anti-blocking permeable road surface structure. As Figures 1 - 5 shown, in this embodiment, the filtering assembly 3 includes a fixed frame 32, a first filter plate 33, a second telescopic column 34, a second elastic column 35, a connecting block 36, a scraper 37 and a telescopic member 38.

[0078] In this embodiment, the anti-blocking permeable road surface structure further includes a driving assembly 4, and the second telescopic column 34 can move downward under the drive of the driving assembly 4.

[0079] Specifically,

[0080] The fixed frame 32 is arranged in the water permeable hole 11. The first filter plate 33 is arranged outside the fixed frame 32. One side of the first filter plate 33 is fixedly connected to the outer wall of the fixed frame 32, and there is a gap between the other side and the inner wall of the water permeable hole 11. This gap forms a slag discharge port for discharging impurities. The collecting hopper 2 is arranged below this gap. During use, the impurities on the first filter plate 33 enter the collecting hopper 2 through the slag discharge port.

[0081] The top of the fixed frame 32 has a material guiding inclined surface 321. The material guiding inclined surface 321 is inclined from top to bottom, and the lower inclined end of the material guiding inclined surface 321 faces the first filter plate 33 below.

[0082] The second elastic column 35 is arranged inside the fixed frame 32, and the second telescopic column 34 is connected to the second elastic column 35. The connecting block 36 is fixed to the outer wall of the second telescopic column 34. The scraping plate 37 is arranged above the first filter plate 33, and the bottom of the scraping plate 37 is in close contact with the upper surface of the first filter plate 33. The connecting block 36 and the scraping plate 37 are movably connected through the telescopic member 38. The driving assembly 4 is arranged above the second telescopic column 34 and can push the second telescopic column 34 to move downward. When the second telescopic column 34 moves downward, through the cooperation of the connecting block 36 and the telescopic member 38, the scraping plate 37 can be pushed to move towards the slag discharge port to clean the sundries attached to the first filter plate 33. The sundries are pushed into the collection hopper 2, then enter the second slag discharge channel 14 through the first slag discharge channel 13, and finally are guided to the designated position for collection (such as outside the permeable base layer 15). When the pressure on the second telescopic column 34 is released, the second telescopic column 34 moves upward and resets under the action of the second elastic column 35, and the scraping plate 37 also returns to the initial position (close to the fixed frame) under the action of the telescopic member 38 and the connecting block 36.

[0083] Further, the telescopic member 38 includes a telescopic rod 381, a connecting ring 382, a first spring 383 and a roller 384.

[0084] One side of the connecting block 36 away from the telescopic member 38 is fixedly connected to the second telescopic column 34, and the other side has an inclined surface 361. The inclined surface 361 is arranged to expand from the lower end to the upper end, and a chute is arranged on the inclined surface 361. One end of the telescopic rod 381 is installed with a roller 384 through a mounting plate, the roller 384 is slidably connected to the chute, and the other end of the telescopic rod 381 penetrates through the fixed frame 32 and is connected to the scraping plate 37.

[0085] During use, when the second telescopic column 34 moves under the action of the driving assembly 4, the connecting block 36 will also move synchronously with the second telescopic column 34. Thus, under the action of the roller 384 and the first spring 383, the telescopic rod 381 will be driven to extend or retract. Thereby, the telescopic rod 381 drives the scraping plate 37 to move on the upper surface of the first filter plate 33 to remove the sundries on the first filter plate 33 and improve the fluidity of the first filter plate 33.

[0086] Optionally, a plurality of chutes can be arranged on the inclined surface of the connecting block 36, that is, when the connecting block 36 is arranged, its length can be greater than the width of the second telescopic column 34. Correspondingly, the number of telescopic members 38 is adapted to the number of arranged chutes, and the plurality of chutes are arranged at equal intervals, which is beneficial to improving the stability of the movement of the scraping plate 37 and improving the sundries removal effect.

[0087] Optionally, the cross-section of the connecting block 36 is in a triangular structure or a trapezoidal structure, and its long side is located at the top.

[0088] Optionally, the first filter plate 33 is disposed at a chamfered angle on one side of the slag discharge port. The collecting hopper 2 is connected to the outlet of the first filter plate 33 .

[0089] Optionally, a plurality of first filter plates 33 are provided, and accordingly, the number of collecting buckets 2 matches the number of first filter plates 33. Figure 1 As shown, in this scenario, two first filter plates 33 are provided, and the fixed frame 32 is provided in the middle position of the water permeable hole 11, with its two ends connected to the inner wall of the water permeable hole, and there is a gap between the two sides and the water permeable hole 11, and the gap forms two filtration channels, and two material guide slopes 321 facing both sides are formed on the top of the fixed frame 32, and the lower end of the material guide slope 321 is inclined toward the filtration channel, and a first filter plate 33 is respectively provided in the two filtration channels, and a collecting bucket 2 is respectively provided at the slag discharge port of the two first filter plates 33. As another implementation scenario, in this scenario, four first filter plates 33 are provided, and the fixed frame 32 is connected to the middle position of the water permeable hole 11 through a support rod. Gaps are formed on the four side walls of the fixed frame 32 and the inner wall of the water permeable hole to form four filtration channels. Four material guide slopes 321 inclined in four directions are formed on the top of the fixed frame 32. The lower end of the material guide slope 321 is inclined toward the filtration channel. A first filter plate 33 is respectively provided in the four filtration channels, and a collection bucket 2 is respectively provided at the slag discharge port of the four first filter plates 33.

[0090] Example 4

[0091] On the basis of Embodiment 3, in this embodiment, the driving assembly 4 includes a first telescopic column 41 and a first elastic column 42 , a rotating shaft 43 and a toggle rod 44 .

[0092] The first telescopic column 41 is longitudinally movable and arranged in the pavement body 1, and the first elastic column 42 is connected to the bottom of the first telescopic column 41, and is used to extend the upper end of the first telescopic column 41 outside the pavement body 1. One end of the rotating shaft 43 is transmission-connected to the first telescopic column 41, and the other end is rotationally connected to the inner wall of the water-permeable hole 11. The toggle rod 44 is connected to the outer wall of the rotating shaft 43, and the second telescopic column 34 can move downward under the action of the toggle rod 44.

[0093] In one embodiment, the rotating shaft 43 is arranged above the fixed frame 32 and close to the fixed frame 32. The top of the second telescopic column 34 or the connecting block 36 is connected to the contact block 341 through a support rod. One end of the support rod is connected to the second telescopic column 34, and the other end passes through the fixed frame 32 and is connected to the contact block 341. The position of the contact block 341 corresponds to the position of the toggle rod 44. When in use, one end of the toggle rod 44 can contact the contact block 341 at the top of the second telescopic column 34 and move the second telescopic column 34 downward. When the toggle rod 44 rotates away from the contact block 341 with the rotating shaft 43, the second telescopic column 34 can move upward and reset under the action of the second elastic column 35.

[0094] In another embodiment, the rotating shaft 43 can also be set in the fixed frame 32, that is, the rotating shaft 43 is located between the rotating shaft 43 and the second telescopic column 34. When the toggle rod 44 rotates with the rotating shaft 43, it can directly contact the top of the second telescopic column 34 or contact the set contact block to move the second telescopic column 34 downward.

[0095] Optionally, multiple contact blocks 341 may be provided, and correspondingly, multiple toggle rods 44 may also be provided. Exemplarily, the upper surfaces of the two connecting blocks 36 are respectively connected with multiple contact blocks through supporting rods, and two sets of driving components are respectively provided above the two connecting blocks 36, and multiple toggle rods 44 corresponding to the contact blocks are respectively provided on the rotating shafts of the two sets of driving components, so that when the multiple toggle rods 44 are driven by the rotating shaft 43, they can simultaneously apply pressure to the second telescopic column 34.

[0096] Optionally, the rotating shaft 43 is transversely and rotatably arranged at the upper part of the water permeable hole 11, and is connected to the first telescopic column 41 through the rotating shaft 43, so as to convert the longitudinal movement of the first telescopic column 41 into the rotational movement of the rotating shaft 43 around its own axis. As an implementation scenario, for example, a transmission tooth can be arranged on the rotating shaft 43, and the first telescopic column 41 has a transmission groove 411 meshing with the transmission tooth; the transmission tooth and the transmission groove 411 mesh, so as to convert the longitudinal movement of the first telescopic column 41 into the rotational movement of the rotating shaft 43 around its own axis.

[0097] When in use, when a person or vehicle passes by the pavement body 1, the first telescopic column 41 is pressed and moves downward. After the pressure on the first telescopic column 41 is released, the first telescopic column 41 moves upward and resets under the reset force of the first elastic column 42, so that the upper end of the first telescopic column 41 re-extends outside the pavement body 1. When the first telescopic column 41 is pressed and drives the rotating shaft 43 to rotate, one end of the toggle rod 44 contacts the second telescopic column 34 and moves the second telescopic column 34 downward. When the second telescopic column 34 moves downward, the connecting block 36 also moves synchronously with the second telescopic column 34, so that the telescopic rod 381 is extended under the action of the roller 384 and the first spring 383, so that the scraper 37 scrapes the debris on the upper surface of the first filter plate 33 to the slag discharge port and falls into the collection bucket 2. Finally, the debris enters the second slag discharge channel 14 after passing through the first slag discharge channel 13, and then is guided to a designated location for collection (such as outside the permeable base layer 15). In this embodiment, the scraper 37 is provided to effectively prevent the first filter plate 33 from being affected in normal use due to the accumulation of debris on the first filter plate 33 .

[0098] In another embodiment, the driving assembly 4 may also only include the first telescopic column 41. The first telescopic column 41 is longitudinally movably arranged in the pavement body 1, and its bottom is directly connected to the top of the second telescopic column 34. Under the action of the second telescopic column 34 and the second elastic column 35, the upper end of the first telescopic column 41 can be extended outside the pavement body 1. When people or vehicles pass by on the pavement body 1, the first telescopic column 41 is pressed and moves downward, which can drive the second telescopic column 34 to move downward synchronously.

[0099] In other embodiments, the driving assembly 4 may also use a driving motor to intermittently drive the second telescopic column 34 to move. Exemplarily, in this embodiment, the driving element includes a driving motor and a rotating shaft connected to the power output end of the driving motor, and a toggle rod is fixed to the outer wall of the rotating shaft. The driving motor is started intermittently, and the rotating shaft drives the toggle rod to rotate under the drive of the driving motor, and the second telescopic column can move downward under the drive of the toggle rod.

[0100] Example 5

[0101] On the basis of Example 3 or Example 4, in this embodiment, the filter assembly 3 further includes a second filter plate 39, which is movably arranged below the first filter plate 33, and a dredging assembly 5 is fixedly arranged below the second filter plate 39. The second filter plate 39 can move synchronously with the second telescopic column 34, and when the second filter plate 39 moves downward, it can contact the dredging assembly 5 below, and the dredging assembly 5 dredges the mesh of the second filter plate 39. In this embodiment, by setting the second filter plate 39, it is possible to further prevent debris from entering the seepage hole 12 and clogging it, and the dredging assembly 5 can ensure the fluidity of the second filter plate 39.

[0102] Optionally, the dredging component 5 includes a fixing plate 51 and a dredging member 52 disposed on the fixing plate 51. One side of the fixing plate 51 is connected to the side wall of the fixing frame 32, and the other side is connected to the inner wall of the water permeable hole 11.

[0103] Optionally, the second filter plate 39 is connected to the second telescopic column 34 through a connecting rod 391. An installation groove 322 is formed on the side wall of the fixing frame 32 on one side of the second filter plate 39. One end of the connecting rod 391 is connected to the second telescopic column 34, and the other end passes through the installation groove 322 and is connected to the second filter plate 39. The connecting rod 391 is in sliding fit with the installation groove 322. A second spring 392 is connected between the connecting rod 391 located in the installation groove 322 and the bottom wall of the installation groove 322.

[0104] Optionally, a sliding groove for the connecting rod 391 to slide is formed on the installation groove 322. A baffle 393 is connected between the second filter plate 39 and the connecting rod 391. The baffle 393 is hermetically attached to the sliding groove, and the length of the baffle 393 is greater than the length of the sliding groove. A through groove is formed at one end of the fixing plate 51 close to the fixing frame 32. The baffle 393 can pass through the through groove when moving downward with the connecting rod 391.

[0105] During use, when the second telescopic column 34 moves downward under the action of the driving component 4, the second filter plate 39 can be synchronously driven to move downward through the connecting rod 391. When the second filter plate 39 moves downward, the lower dredging member 52 can pass through the mesh holes of the second filter plate 39 to dredge it. The dredging member 52 is adapted to the size of the mesh holes of the second filter plate 39, such as using a dredging needle.

[0106] In an embodiment, the baffle 393 can be abutted against or telescopically connected to the first filter plate 33 in the initial state. In this way, when the second telescopic column 34 is not pressed and restored, the baffle 393 can contact the first filter plate 33 when moving upward with it, thereby generating vibration for the first filter plate 33 and ensuring the fluidity of the first filter plate 33.

[0107] In an embodiment, the elastic column can adopt a sliding sleeve, and the telescopic column is slidably connected to the sliding sleeve through a telescopic spring.

[0108] Embodiment 6

[0109] Based on Embodiments 3-5, the embodiment of the present invention provides an anti-blocking and permeable pavement structure. In this embodiment, a drain pipe 6 is also connected between the fixed frame 32 and the first slag discharge channel 13. An inlet is opened on the side wall of the fixed frame 32, and the permeable holes 11 are connected to the inside of the fixed frame 32 through the inlet. The bottom of the fixed frame 32 has an outlet. One end of the drain pipe 6 is connected to the outlet, and the other end is connected to the first slag discharge channel 13. A buoyancy switch assembly 7 is provided on the outlet. When the depth of rainwater in the fixed frame 32 is equal to or slightly greater than the surface of the collection hopper 2, the buoyancy switch assembly 7 is opened, and the rainwater in the fixed frame 32 enters the drain pipe 6 through the outlet. By adding the drain pipe 6, on the one hand, when the permeable holes 11 are filled with rainwater, the rainwater in the permeable holes 11 can be discharged to the first slag discharge channel 13 and the second slag discharge channel 14 through the collection hopper 2 and the drain pipe 6 at the same time, thereby increasing the amount of water entering the first slag discharge channel 13. The increase in the amount of water is beneficial to increasing the water pressure in the slag discharge channel, that is, it can increase the impact force on the slag discharge channel, making it easier to discharge the sundries. On the other hand, when the collection hopper 2 is blocked or the drainage effect is not good, at this time, since the liquid in the fixed frame 32 is filtered, the drain pipe 6 can be used as a standby drainage pipeline to dredge the slag discharge pipeline with the drain pipe 6.

[0110] Optionally, a guide column 323 is installed on the outlet of the fixed frame 32. The guide column 323 includes a circulation port 3231 and a diversion port 3232. The circulation port 3231 is vertically arranged, and its lower end is connected to the drain pipe. The diversion port 3232 is horizontally arranged and connected to the upper end of the circulation port 3231, that is, the circulation port 3231 and the diversion port 3232 form a "T" - shaped structure.

[0111] As an implementation scenario, in this scenario, the buoyancy switch assembly 7 includes: a fixed seat 71, a sleeve 72, a lever 73 and a floating ball 74.

[0112] The fixed seat 71 is arranged on one side of the guide column 323. The top of the sleeve 72 is closed and the bottom is open. The inner diameter of the sleeve 72 is adapted to the outer diameter of the guide column 323. When the sleeve 72 covers the guide column 323, it can close the diversion port 3232. The top of the sleeve 72 is hinged to the lever 73 through a hinge shaft, and one end of the lever 73 is also hinged to the fixed seat 71 beside the sleeve 72 through a hinge shaft. The other end of the lever 73 is hinged to the floating ball 74.

[0113] During use, in the initial state, the floating ball 74 is located at the bottom position of the fixed frame 32 under the action of gravity. At this time, under the action of the floating ball 74, the end of the lever 73 far from the sleeve 72 is located at the bottom position of the fixed frame 32 to close the guide column 323. Refer to Figure 3The lever 73 shown is in a horizontal state to close the diversion column 323. Alternatively, the floating ball 74 is located on the inner bottom surface of the fixed frame 32 and the lever is in an inclined state. When the rainwater stored in the fixed frame 32 increases and the buoyancy of the water is greater than the gravity of the floating ball 74, the floating ball 74 rises as the liquid level rises. The rising floating ball 74 drives the lever 73 to swing upward, so that the sleeve 72 releases the closure of the diversion column 323, so that the inner cavity of the fixed frame 32 is communicated with the diversion port 3232 of the diversion column 323, and the rainwater in the fixed frame 32 is discharged into the drain pipe 6 through the diversion port 3232 and the circulation port 3231. As the rainwater in the fixed frame 32 decreases, the floating ball 74 resets under the action of gravity. When setting, the opening force of the sleeve 72 can be set by the difference between the buoyancy and the gravity of the floating ball 74, and the gravity of the floating ball can be adjusted by adding a counterweight to control the floating ball to start floating when the water level is equal to or higher than the collection hopper 2 to open the diversion column 323.

[0114] Optionally, the position of the water inlet on the fixed frame 32 can be set close to the first filter plate 33. When in use, when the rainwater in the water permeable holes 11 approaches the collection hopper 2, the rainwater in the water permeable holes 11 can enter the fixed frame 32 through the water inlet.

[0115] Embodiment 7

[0116] The embodiment of the present invention provides an anti-blocking permeable road surface structure. On the basis of any of the above embodiments, refer to Figure 2 or Figure 7 As shown, the anti-blocking permeable road surface structure further includes a water absorption component 8.

[0117] Specifically,

[0118] A water storage cavity 16 is further provided on the road surface body 1, and the water storage cavity 16 is communicated with the side wall of the water seepage hole 12 through a channel 17.

[0119] The water absorption component 8 includes a water absorption rod 81. An installation hole matching the water absorption rod 81 is provided on the road surface body 1 above the water storage cavity 16. One end of the water absorption rod 81 is located in the water storage cavity 16, and the other end is communicated with the external environment through the installation hole. The water storage cavity 16 serves to store a small amount of rainwater. After the water absorption rod 81 absorbs water, it becomes wet as a whole and can evaporate the rainwater into the external environment, thereby increasing the humidity near the surface of the road surface body 1 and achieving the effect of dust reduction.

[0120] Furthermore, the water absorption component 8 further includes a water absorption expansion rubber 82 and a weight pressing plate 83. The water absorption expansion rubber 82 is arranged at the bottom of the water storage cavity 16, and the water absorption expansion rubber 82 expands when it encounters water; the weight pressing plate 83 is fixed to the lower part of the water absorption rod 81 and is in contact with the upper side of the water absorption expansion rubber 82.

[0121] During use, on sunny days, the water-absorbing and swelling rubber 82 is not swollen, and the top of the water-absorbing rod 81 is located near the lower surface of the road surface body 1 (that is, the top of the water-absorbing rod 81 is located near the lower part of the top of the installation hole). The top of the water-absorbing rod 81 and the installation hole together form a receiving groove 18, and the receiving groove 18 functions to collect and store dust. After the rainwater absorbed by the water-absorbing rod 81 evaporates, the dust in the receiving groove 18 agglomerates, preventing a large amount of dust from being generated when people and vehicles pass by. On rainy days, rainwater can enter the water storage cavity 16, and the water-absorbing and swelling rubber 82 absorbs water and swells, causing the counterweight pressing plate 83 to drive the water-absorbing rod 81 to move upward a certain distance, so that the top of the water-absorbing rod 81 is flush with the top of the installation hole. When the rainwater in the water storage cavity 16 is consumed on sunny days, the agglomerated dust in the receiving groove 18 is likely to harden and adhere to the inner wall of the receiving groove 18. Under the push of the top of the water-absorbing rod 81 (the water-absorbing and swelling rubber 82 absorbs water and swells, causing the counterweight pressing plate 83 to drive the water-absorbing rod 81 to move upward a certain distance), the hardened agglomerated dust can be broken and moved outside the road surface body 1; after the hardened agglomerated dust is broken, it is not only easier to be washed away by rainwater, but also not easily block other holes in the road surface body 1.

[0122] Embodiment 8

[0123] The water permeability effect of the permeable road surface can be evaluated by the seepage velocity measured by Darcy's law of permeability. This embodiment provides a method for detecting the anti-blocking effect of the anti-blocking permeable road surface structure. This anti-blocking effect detection method can be used to detect the anti-blocking permeable road surface structure described in the above embodiments to assist in the design and research of the anti-blocking permeable road surface. The specific steps of this anti-blocking effect detection method are as follows:

[0124] Step S1: Detect the seepage velocity of the anti-blocking permeable road surface structure in the unblocked state to obtain the initial seepage velocity;

[0125] Step S2: Apply the blocking material on the surface of the anti-blocking permeable road surface structure so that the blocking material blocks the upper part of the water permeable holes 11 of the anti-blocking permeable road surface structure;

[0126] Step S3: Let the blocking material dry and harden;

[0127] Step S4: Detect the seepage velocity of the anti-blocking permeable road surface structure in the blocked state to obtain the blocked seepage velocity;

[0128] Step S5: Repeat Step S2 and Step S3;

[0129] Step S6: Roll a roller on the surface of the anti-blocking permeable road surface structure in the blocked state;

[0130] During the process of rolling with the roller, the hardened blocking material in the water permeable holes 11 can be broken;

[0131] Step S7: Simulate rainfall to cause rainwater to gather on the surface of the anti-blocking permeable pavement structure, so as to restore the anti-blocking ability of the anti-blocking permeable pavement structure;

[0132] Step S8: Detect the penetration speed of the anti-blocking permeable pavement structure to obtain the unclogging penetration speed;

[0133] Step S9: Compare the initial penetration speed, the blocked penetration speed, and the unclogging penetration speed to obtain the anti-blocking effect of the anti-blocking permeable pavement structure.

[0134] In Step S1, Step S4, and Step S8, when detecting the penetration speed, a device based on the measurement principle of Darcy's law of permeability is used for detection.

[0135] By adopting the above anti-blocking effect detection method, the initial penetration speed, the blocked penetration speed, and the unclogging penetration speed of the anti-blocking permeable pavement structure can be compared, so as to obtain an evaluation of the anti-blocking effect of the anti-blocking permeable pavement structure, thereby assisting in the design and research of the anti-blocking permeable pavement structure.
