Description

Technical Field

[0001] The invention relates to the technical field of road maintenance, and in particular to a road pavement water permeability detection device. Background Art

[0002] When the road surface is soaked in water for a long time, water will gradually fill into the gaps in the road surface, affecting the adhesion of the materials in the road surface. Under the repeated action of vehicle loads, cracks or potholes will appear on the road surface. Therefore, after the road is built, it is necessary to test the road surface for water seepage.

[0003] For example, Chinese invention CN116698705A discloses a road surface water seepage detection device for road construction. The water seepage detection device automatically opens the exhaust pipe during the measurement process by setting a measuring component, and seals the exhaust pipe when the exhaust pipe is filled with water. At the same time, the exhaust pipe can be driven to open after the detection is completed, so as to discharge the water in the exhaust pipe.

[0004] As shown in the above-mentioned referenced documents, the road pavement water permeability detection device in the prior art is currently unable to effectively remove the debris and dust in the road surface area to be detected to the outside of the detection area before the water permeability detection operation during actual use. The debris remaining in the detection area will affect the road pavement water permeability detection.

[0005] If manual cleaning is used to clean the road surface to be tested, since the road surface cleaning and the subsequent water permeability test are carried out separately, after the area to be tested in the road is cleaned, the detection device needs to be moved into the detection area. During the movement of the detection device, some dust and impurities in the air will still enter the area to be tested again, affecting the detection accuracy of the subsequent permeability test.

Under the action of multiple bristles under the cleaning disk, not only can the dust and debris on the road surface to be tested be cleaned, but also the dust and debris on the road surface to be tested can be pushed to the outside of the detection box as the cleaning disk reciprocates. The cleaning effect is good, and the problem that the debris and dust will affect the subsequent water permeability detection of the road surface is avoided.

[0027] 3. After the road surface to be inspected is cleaned, the present invention turns off motor 1, and under the action of the elastic potential energy of three springs, the cleaning disk can be automatically pulled back to the position coaxial with the eccentric disk, and then the hydraulic assembly is controlled again to drive the limit frame to move upward and reset, so that the two cleaning disks can be retracted into the interior of the inspection box again. At the same time, the rubber sealing ring layer will also drop to the position in contact with the road surface again, so that after the road surface to be inspected is cleaned, the sealing operation between the inspection box and the road surface can be automatically completed. The device has high integration, which provides convenience for subsequent water injection and water permeability detection.

[0028] 4. The present invention starts the water pump to fill water into the interior of the test box. After the water is filled, the liquid level indicated by the scale on the visual window is observed to be h1. After a period of time, the liquid level indicated by the scale is observed again to be h2. The difference h3 is calculated by calculating h1-h2, and whether the water permeability of the road surface meets the standard can be intuitively judged. The detection steps are simple and convenient, and it is worthy of promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] For example, see Figures 1 to 7The present invention provides a road pavement water permeability detection device, including a detection box 1, a hydraulic component 13 is arranged on the upper surface of the detection box 1, a limit frame 14 is fixedly installed on the output end of the hydraulic component 13, the inner wall of the limit frame 14 is slidably connected to two symmetrically arranged connecting plates 15, the lower surface of the connecting plate 15 is fixedly rotatably connected to a connecting column 20, the end of the connecting column 20 is fixedly connected to a cleaning disk 19, the lower surface of the cleaning disk 19 is provided with bristles, the inner wall of the detection box 1 is slidably connected to a connecting ring 22, the lower end of the connecting ring 22 is provided with a rubber sealing ring layer 2, and the detection box 1 is provided with a cleaning component, an auxiliary component and a switching component.

[0039] A visual window 5 is provided on the surface of the detection box 1, and the visual window 5 is made of transparent material. A scale 6 is provided on the surface of the visual window 5. A water tank 12 is fixedly installed on the upper surface of the detection box 1. The surface of the water tank 12 is fixedly connected with a water outlet pipe 10, and a water pump 11 is provided on the surface of the water tank 12. Two door bodies 9 are hinged on the upper surface of the detection box 1, and handles are provided on the surface of the door bodies 9. A fixed plate 8 is fixedly connected to the surface of the detection box 1, and a universal wheel 7 is provided on the lower surface of the fixed plate 8. The surface of the detection box 1 is provided with an armrest.

[0040] The cleaning component includes a rectangular notch opened on the inner wall of the detection box 1, a slider 52 is slidably connected to the inner wall of the rectangular notch, a motor 24 is fixedly installed on the end of the slider 52, a threaded rod 25 is fixedly connected to the output shaft of the motor 24, a mounting plate 30 is fixedly connected to the inner wall of the detection box 1, a rectangular frame 28 is fixedly connected to the mounting plate 30, a moving block 36 is slidably connected to the inner wall of the rectangular frame 28, and the threaded rod 25 penetrates the moving block 36 and is threadedly connected thereto;

[0041] A support plate 1 29 is fixedly mounted on the surface of the rectangular frame 28, a rotating rod 27 is rotatably connected to the surface of the support plate 1 29, a gear 1 26 is fixedly connected to the surface of the threaded rod 25, a gear 2 meshing with the gear 1 26 is fixedly connected to the surface of the rotating rod 27, and a plurality of protrusions 31 distributed in a circumferential array are fixedly connected to the surface of the rotating rod 27;

[0042] It also includes a sleeve 35, which is sleeved on the outer surfaces of the multiple protrusions 31 and the rotating rod 27. The surface of the sleeve 35 is rotatably connected to a movable ring 32. The end of a movable block 36 is fixedly connected to the movable ring 32. The surface of the movable ring 32 is rotatably connected to a rotating shaft 16. A bevel gear transmission mechanism 34 is commonly provided between the rotating shaft 16 and the sleeve 35.

[0043] In this embodiment, Figure 1 As shown, by pushing the handrail, the detection box 1 can be pushed to the position where the water permeability detection of the road surface is required under the action of the universal wheel 7.

[0044] After the detection box 1 reaches the detection position, Figure 2 , Figure 3 and Figure 4 As shown, first control the hydraulic assembly 13 to drive the limit frame 14 to descend until the cleaning disk 19 below moves down to a position in contact with the ground, then turn on the motor 1 24, and under the transmission action of the gear 1 26 and the gear 2, drive the threaded rod 25 and the rotating rod 27 to rotate synchronously. Since the sleeve 35 is sleeved on the outer surfaces of the plurality of protrusions 31 and the rotating rod 27, as the rotating rod 27 rotates, the sleeve 35 will be driven to rotate synchronously. As the sleeve 35 rotates, under the transmission action of the bevel gear transmission mechanism 34, the rotating shaft 16 will be driven to rotate. As the rotating shaft 16 rotates, the eccentric disk 17 will be caused to rotate eccentrically in the circular inner cavity 18 in the front and rear directions with the axis of the rotating shaft 16. When the eccentric disk 17 contacts the inner wall of the circular inner cavity 18, the cleaning disk 19 will be pushed to eccentrically deflect toward the outside of the detection box 1 with the connecting column 1 20 as the axis.

[0045] It is worth noting that Figure 3 and Figure 4 As shown, after the motor 1 24 is turned on, as the threaded rod 25 rotates, the moving block 1 36 will move to the left. As the moving block 1 36 moves, under the connection action of the support plate 2 33, the eccentric disk 17 and the cleaning disk 19 below will move synchronously away from the outside of the detection box 1.

[0046] In summary, by turning on the motor 24, under the linkage cooperation of multiple structures, the cleaning disc 19 can be made to move toward the outside of the detection box 1 while reciprocating in the front and rear directions. Under the action of multiple bristles under the cleaning disc 19, not only can the dust and debris on the road surface to be tested be cleaned, but also the dust and debris on the road surface to be tested can be pushed to the outside of the detection box 1 as the cleaning disc 19 reciprocates and moves, so that the cleaning effect is good, and the problem that the debris and dust will affect the subsequent road permeability detection can be avoided.

[0047] Embodiment 2, based on the above embodiment:

[0048] Furthermore, the auxiliary component includes a broken gear 38 fixedly connected to the surface of the connecting column 1 20, a slide groove is provided on the lower surface of the connecting plate 15, a moving block 2 41 is slidably connected to the inner wall of the slide groove, a rack row 1 37 meshing with the broken gear 38 is fixedly connected to the lower surface of the moving block 2 41, an articulated block 1 is fixedly connected to the end of the rack row 1 37, and an articulated plate 47 is articulated to the surface of the articulated block 1;

[0049] A piston cylinder 44 is fixedly mounted on the lower surface of the connecting plate 15, a piston plate is slidably connected to the inner wall of the piston cylinder 44, a piston rod 45 is fixedly connected to the surface of the piston plate, an articulated block 46 is fixedly connected to the end of the piston rod 45, an end of the articulated plate 47 is hinged to the articulated block 46, and a spring 2 is commonly arranged between the articulated block 46 and the piston cylinder 44.

[0050] A water storage cylinder 51 is fixedly mounted on the upper surface of the connecting plate 15, a connecting pipe 1 48 is fixedly connected between the water storage cylinder 51 and the piston cylinder 44, and a connecting pipe 2 is fixedly connected to the surface of the piston cylinder 44;

[0051] An arc-shaped inner cavity 53 is provided inside the cleaning disk 19 , a connecting pipe 3 49 is fixedly connected to the surface of the cleaning disk 19 , a hose is fixedly connected between the connecting pipe 3 49 and the connecting pipe 2 , and a plurality of water outlets 50 are provided on the side of the cleaning disk 19 .

[0052] In this embodiment, Figure 4 and Figure 7 As shown, with the motor 24 turned on, when the cleaning disk 19 deflects back and forth in the front-back direction with the center of the connecting column 20 as the center, it will also drive the connecting column 20 to rotate back and forth. With the reciprocating rotation of the connecting column 20, the residual gear 38 will be driven to rotate back and forth, so that the rack row 37 can move back and forth in the front-back direction. Under the hinged action of the hinged plate 47, the reciprocating movement of the rack row 37 will cause the piston rod 45 to drive the piston plate to perform piston movement in the piston cylinder 44. , so that the clean water in the water storage cylinder 51 can be transported to the arc-shaped inner cavity 53 through the hose between the connecting pipe three 49 and the connecting pipe two, and the clean water in the arc-shaped inner cavity 53 will be evenly sprayed out through the multiple water outlets 50. Since the multiple water outlets 50 are opened on the side of the cleaning disk 19, the road surface can be wetted before the cleaning disk 19 cleans the road surface to be inspected, so as to prevent stubborn dust from adhering to the road surface, thereby further improving the cleaning effect of the cleaning disk 19 on the road surface to be inspected.

[0053] It is worth noting that when the moving block 36 drives the cleaning disk 19 to move toward the outside of the detection box 1, the connecting plate 15 and the piston cylinder 44 move toward the outside of the detection box 1 together with the cleaning disk 19, and when the cleaning disk 19 reciprocates in the front-to-back direction with the center of the connecting column 20 as the center, the piston movement will be performed in the piston cylinder 44. Therefore, when the cleaning disk 19 moves toward the outside of the detection box 1, it will not affect the piston movement in the piston cylinder 44.

[0054] Embodiment 3, based on the above embodiment,

[0055] Furthermore, the switching component includes a motor 2 3 fixedly mounted on the surface of the detection box 1, the output shaft of the motor 2 3 is fixedly connected to the rotating shaft 2, the surface of the rotating shaft 2 is fixedly connected to the gear 3 43, the upper surface of the connecting ring 22 is fixedly connected to the rack row 2 42 meshing with the gear 3 43, the surface of the limit frame 14 is fixedly connected to the connecting rod, and the end of the connecting rod is fixedly connected to the rack row 3 54 meshing with the gear 3 43.

[0056] In this embodiment, Figure 5 and Figure 6 As shown, when the hydraulic assembly 13 is controlled to drive the limit frame 14 to descend so that the cleaning disk 19 moves down to a position in contact with the ground, as the limit frame 14 descends, the rack row three 54 will be driven to move down synchronously, and the gear three 43 will be driven to rotate, and under the meshing action of the gear three 43 and the rack row two 42, the rack row two 42 will move upward, so that the connecting ring 22 can drive the rubber sealing ring layer 2 to move upward, that is, when the cleaning disk 19 moves down to a position in contact with the ground, the rubber sealing ring layer 2 will also rise to the inside of the detection box 1, so as to no longer seal the detection box 1 and the ground, and then the motor 1 24 is turned on, and the road surface can be cleaned by the reciprocating deflection of the cleaning disk 19.

[0057] After the road surface is cleaned, the motor 24 is turned off. Under the action of the elastic potential energy of the three springs 39, the cleaning disc 19 is pulled back to the position coaxial with the eccentric disc 17. Then the hydraulic assembly 13 is controlled again to drive the limit frame 14 to move upward and reset. Similarly, the two cleaning discs 19 can be retracted into the interior of the detection box 1 again. At the same time, the rubber sealing ring layer 2 will also drop to the position in contact with the road surface again, so as to complete the sealing after the cleaning of the road surface to be detected is completed.

[0058] Then, turn on the water pump 11 to fill the test box 1 with water through the water outlet pipe 10. After the water filling is completed, observe that the liquid level indicated by the scale 6 on the visual window 5 is h1. After a period of time, observe the liquid level indicated by the scale 6 again as h2. Calculate h1-h2 to get the difference h3, and judge whether the difference h3 meets the water seepage standard, that is, it can be judged whether the water permeability of the road surface meets the standard. At this point, the water permeability test of the road surface is completed.

[0059] The two doors 9 on the upper surface of the detection box 1 can facilitate the operator to open the detection box 1 to add water to the water storage cylinder 51 and to inspect or replace the parts in the detection box 1, which is more practical.

[0060] Working principle: When using this road pavement water permeability detection device, push the handrail to push the detection box 1 to the position where the road pavement needs to be tested for water permeability. After the detection box 1 reaches the detection position, control the hydraulic component 13 to drive the limit frame 14 to descend until the cleaning disk 19 moves down to a position in contact with the ground. During this process, under the meshing action of rack row 2 42, gear row 3 43 and rack row 3 54, the connecting ring 22 will drive the rubber sealing ring layer 2 to move upward to the inside of the detection box 1.

[0061] Then, the motor 24 is turned on, and with the linkage cooperation of multiple structures, the cleaning disc 19 moves toward the outside of the detection box 1 while reciprocating in the front-to-back direction with the connecting column 20 as the axis. Under the action of multiple bristles under the cleaning disc 19, not only can the dust and debris on the road surface to be tested be cleaned, but also the dust and debris on the road surface to be tested can be pushed to the outside of the detection box 1 as the cleaning disc 19 reciprocates. The cleaning effect is good, and the problem that the debris and dust will affect the subsequent water permeability detection of the road surface is avoided.

[0062] While the cleaning disc 19 is reciprocatingly deflected in the front-to-back direction with the connecting column 20 as the axis, it will also drive the connecting column 20 to rotate back and forth, and make the rack row 37 reciprocate in the front-to-back direction. Under the hinged action of the hinged plate 47, the piston rod 45 can drive the piston plate to perform piston movement in the piston cylinder 44, so that the clean water in the water storage cylinder 51 can be transported to the arc-shaped inner cavity 53 through the hose, and sprayed out evenly from multiple water outlets 50, so that before the cleaning disc 19 cleans the road surface to be inspected, the road surface can be wetted to prevent stubborn dust from adhering to the road surface, thereby further improving the cleaning effect of the cleaning disc 19 on the road surface to be inspected.

[0063] After the road surface to be inspected is cleaned, the motor 24 is turned off. Under the action of the elastic potential energy of the three springs 39, the cleaning disc 19 is automatically pulled back to the position coaxial with the eccentric disc 17. Then the hydraulic assembly 13 is controlled again to drive the limit frame 14 to move upward and reset. Similarly, the two cleaning discs 19 can be retracted into the interior of the inspection box 1 again. At the same time, the rubber sealing ring layer 2 will also drop to the position in contact with the road surface again, so as to complete the sealing operation after the road surface to be inspected is cleaned.

[0064] Then, turn on the water pump 11 to fill water into the interior of the test box 1 through the water outlet pipe 10. After the water filling is completed, observe that the liquid level indicated by the scale 6 on the visual window 5 is h1. After a period of time, observe the liquid level indicated by the scale 6 again as h2. Calculate h1-h2 to get the difference h3, which can determine whether the water permeability of the road surface meets the standard. At this point, the water permeability test of the road surface is completed.
