DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are partial embodiments of the present invention, rather than all embodiments.

[0022] In the description of the present invention, it should be understood that the terms "center", "lateral", "longitudinal", "front", "back", "left", "right", "up", "down", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the scope of protection of the present invention. When a component is referred to as being "fixed to" another component, it may be directly on the other component or there may also be a centered component. When a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centered component at the same time. When a component is considered to be "set on" another component, it may be directly set on the other component or there may be a centered component at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0023] like Figures 1 to 12 As shown, the present invention is a water seepage detection device for asphalt pavement, comprising: a detection mechanism 1 for detecting the asphalt pavement, a support mechanism 2 for supporting the detection mechanism 1, the support mechanism 2 prevents the detection mechanism 1 from tilting during the detection process to affect the detection effect; the detection mechanism 1 comprises: a measuring cylinder 12, the measuring cylinder 12 is used to store water and the amount of water storage decreases can be observed to calculate the water permeability of the asphalt road; the support mechanism 2 comprises: a base 23, a limit frame 21, and a water injection component 22 for injecting water into the measuring cylinder 12. By injecting water into the measuring cylinder 12 through the water injection component 22, the effort consumed by manually injecting water into the measuring cylinder 12 from the upper end opening of the measuring cylinder 12 during detection can be reduced, and the tediousness of detection can be reduced. Similarly, pre-watering can be performed before reaching the detection area to speed up the detection efficiency.

[0024] The water injection assembly 22 includes: a sac 221, an infusion tube 2211 connected to the sac 221, a connecting tube 2212 connected to the infusion tube 2211, a horizontal piece 2213 connected to the connecting tube 2212, a discharge tube 2214 connected to the horizontal piece 2213, a discharge port 2215 provided in the discharge tube 2214, and a valve 1 installed in the connecting tube 2212; the infusion tube 2211 is connected to the measuring cylinder 12, and a valve 2 is installed in the infusion tube 2211, wherein the valve 1 is an electrically controlled valve and the valve 2 is a one-way valve.

[0025] Water is added to the bladder 221. When the bladder 221 is under pressure, the water is discharged into the horizontal piece 2213 and the measuring cylinder 12 through the infusion tube 2211, thereby avoiding manual water addition into the measuring cylinder 12, increasing the degree of manual participation, and making the detection process cumbersome. In addition, under the action of valve 1 and valve 2, the water in the bladder 221 enters the measuring cylinder 12. When detection is required, the water in the measuring cylinder 12 enters the discharge pipe 2214 through the connecting tube 2212 and the horizontal piece 2213 and is discharged through the discharge port 2215 for detection. This optimizes the step of manually injecting water into the measuring cylinder 12 at the detection site in the prior art and improves the detection efficiency.

[0026] When the capsule 221 is squeezed, the liquid enters the horizontal member 2213. Since the horizontal member 2213 is fixedly mounted with a porous plate 22131 with multiple groups of small holes, the horizontal member 2213 is slidably connected with a slide plate 22132, on which a telescopic member 22133 is fixedly mounted, and a sliding member 221321 is slidably connected with the slide plate 22132, on which a liquid leakage port 221322 is provided, and a convex rod 22141 is fixedly mounted on the drain pipe 2214. The telescopic member 22133 is fixedly mounted on the inner wall of the horizontal member 2213, and the end of the horizontal member 2213 away from the capsule 221 is transparent, so that the liquid situation inside the horizontal member 2213 can be observed.

[0027] When the water enters the interior of the horizontal member 2213 through the connecting pipe 2212, the slide plate 22132 is pushed to move toward the drainage pipe 2214 under the impact of the water, and the interior of the horizontal member 2213 is filled through the porous plate 22131. At this time, the sliding member 221321 moves on the slide plate 22132 under the action of the top rod, so that the leakage port 221322 is exposed. At this time, the water that continuously enters the interior of the horizontal member 2213 flows out under the action of the leakage port 221322 and the drainage pipe 2214. When the water in the measuring cylinder 12 is injected, the squeezing of the capsule 221 is stopped. After the water stops entering, the water in the horizontal member 2213 flows out. At this time, the outflow of water in the measuring cylinder 12 is controlled by valve 1 to detect water seepage on the road surface.

[0028] In addition, if the levelness of the horizontal member 2213 and the overall device is within the qualified range, the water between the porous plate 22131 and the transparent end of the horizontal member 2213 forms a water film and cannot pass through the small holes on the porous plate 22131. Water will be stored in the horizontal member 2213, which can be observed through the transparent end of the horizontal member 2213. If the levelness of the horizontal member 2213 and the overall device is unqualified, the water cannot form a water film, which is convenient for measuring the levelness of the detection area and improving the detection effect. It should be noted that the horizontal member 2213 is relatively small in size and contains less water, so that excessive water will not flow out, affecting the water seepage detection effect on the road surface.

[0029] That is to say, by squeezing the capsule 221, the water enters the horizontal piece 2213 and the measuring cylinder 12. The horizontal piece 2213 can detect the horizontality of the device. The water in the measuring cylinder 12 is discharged through the drain port 2215 into the detection seat 2326 for detection, which has a good use effect. By controlling the height of the horizontal piece 2213 (that is, the distance between the transparent end of the horizontal piece 2213 and the end opposite to the transparent end), the detection range of the road surface horizontality can be adjusted, which has a good use effect.

[0030] It should be added to the above that if any foreign matter enters from the upper end of the measuring cylinder 12 during the drainage process of the measuring cylinder 12, it will affect the outflow of water and further affect the accuracy of the test result. Therefore, the measuring cylinder 12 is also provided with a cover plate 11 for closing the inlet of the measuring cylinder 12. The cover plate 11 is composed of: a fixed plate 111 detachably connected to the measuring cylinder 12, a through hole 112 opened on the fixed plate 111, a rotating shaft 113 rotatably mounted on the fixed plate 111, and a rotating plate 114 fixedly mounted on the rotating shaft 113. The fixed plate 111 can block large foreign matter to prevent the foreign matter from entering the interior of the measuring cylinder 12 and causing the water in the measuring cylinder 12 to flow out. In addition, the rotating plate 114 can be driven to rotate by the rotating shaft 113 to move the rotating plate 114 to the bottom of the through hole 112, so that the cover plate 11 completely isolates the measuring cylinder 12 from the outside world. The advantage of doing so is that before squeezing the capsule 221, the rotating shaft 113 is first rotated to move the rotating plate 114 to under the through hole 112, and then the capsule 221 is squeezed. At this time, due to the air pressure in the measuring cylinder 12, the water will preferentially enter the horizontal piece 2213 to detect the horizontality of the detection area, and at the same time, water resources will not be wasted. After the horizontality detection of the horizontal piece 2213 is completed, the rotating shaft 113 is rotated again to move the rotating plate 114 away from under the through hole 112, so that the water in the capsule 221 can normally enter the measuring cylinder 12. On the one hand, the cover plate 11 can prevent foreign matter from entering the interior of the measuring cylinder 12 and affecting the outflow of water from the measuring cylinder 12. On the other hand, the level detection is separated from the water filling of the measuring cylinder 12 to avoid unqualified levelness and the water in the capsule 221 being discharged again, resulting in failure to detect and waste of water resources.

[0031] In order to prevent the uneven road surface or cracks in the road surface from causing water to flow to non-detection areas and affect the detection effect of the road surface, it is usually necessary to seal the base 23 and the road surface after the base 23 contacts the road surface to ensure the accuracy of the detection result.

[0032] The lower bottom plate 212 is fixedly mounted with a base 23, the base 23 is provided with a cavity 231, the cavity 231 is connected with a second liquid outlet pipe 2221, the second liquid outlet pipe 2221 is connected with a second capsule 222, the second capsule 222 is fixedly connected with a connecting rod 2222, one end of the connecting rod 2222 is connected with the upper end of the second capsule 222, the upper end of the second capsule 222 is the end close to the measuring cylinder 12, one end of the connecting rod 2222 is slidably connected with a rotating block 232, the rotating block 232 A liquid inlet 2321 is provided on the side close to the base 23, a slide groove 2322 is provided on the side of the rotating block 232 close to the connecting rod 2222, a side liquid outlet 2323 is provided on the side of the rotating block 232 away from the base 23, an end liquid outlet 233 is provided on the side of the rotating block 232 away from the connecting rod 2222, and a glue outlet is provided on the base 23 to match the position of the liquid inlet 2321; the rotating block 232 is slidably connected to the connecting rod 2222 via the slide groove 2322.

[0033] When squeezing the first bladder 221, the second bladder 222 is squeezed synchronously so that the sealant in the second bladder 222 is discharged into the base 23 through the second liquid outlet pipe 2221, and then enters the interior of the rotating block 232 through the glue outlet and the liquid inlet 2321, and is discharged through the end liquid outlet 233 and the side liquid outlet 2323, thereby sealing the base 23 and the ground, avoiding the gap between the ground and the base 23 during use, which affects the water permeability detection of the asphalt pavement. The sealant is discharged outward through the end liquid outlet 233 and the side liquid outlet 2323, so that the sealing area is larger and the sealing effect is better.

[0034] In addition, when the second capsule 222 is compressed, it drives the connecting rod 2222 to move, and the connecting rod 2222 drives the rotating block 232 to move downward, so as to prevent the sealant from diffusing into the detection area and affecting the water seepage detection of the asphalt pavement. That is to say, when the first capsule 221 and the second capsule 222 are squeezed, the first capsule 221 stores water and detects the horizontality, while the second capsule 222 discharges the sealant for sealing. It is easy to use, simplifies the complexity of asphalt pavement detection, and improves the efficiency of asphalt pavement detection.

[0035] It should be supplemented that a guide member 2324 is fixedly installed on the side of the rotating block 232 away from the base 23, the drain port 2215 is connected to a detection seat 2326, a rotating block 2325 is fixedly installed on the detection seat 2326, an arc groove 23251 is opened on the rotating block 2325, and the arc groove 23251 is slidably connected to the guide member 2324; a baffle 2327 is slidably connected to the detection seat 2326, when the detection seat 2326 contacts the ground, the baffle 2327 moves toward the inside of the detection seat 2326 under the obstruction of the ground, the baffle 2327 can further prevent the sealant from penetrating into the inside of the detection seat 2326, affecting the water seepage detection of the water in the detection seat 2326 and the ground, a reset member is provided between the baffle 2327 and the detection seat 2326, which is used to drive the baffle 2327 to reset, and the reset member can be selected as a spring.

[0036] When the sealant in the capsule 222 is discharged toward the base 23, the positions of the liquid inlet 2321 and the glue outlet do not overlap, and the sealant will exist in the cavity 231 of the base 23. The connecting rod 2222 drives the rotating block 232 to move downward, and under the limiting guidance of the guide member 2324 and the arc groove 23251, the rotating block 232 rotates through the slide groove 2322. At this time, the liquid inlet 2321 and the glue outlet are relative to each other, and the sealant in the cavity 231 can flow out, so that the sealant can delay the triggering of the seal between the ground and the base 23, avoiding direct glue discharge and the detection area failing to meet the detection conditions, resulting in waste of sealant. In addition, one side of the rotating block 232 is in contact with the rotating block 2325. When the rotating block 232 moves downward, it can scrape off the impurities on the side of the rotating block 2325 to avoid affecting the use effect of the detection seat 2326.

[0037] When squeezing capsule 1 221 and capsule 222 to add water and seal, on the one hand, the water is discharged into the horizontal piece 2213 to detect the horizontality of the detection area, and on the other hand, it can drive the rotating block 232 to move and clean the side of the rotating block 2325 to prevent the residual sealant or other impurities on the rotating block 2325 from affecting the water seepage detection of the road surface. After completing the preliminary preparation work of adding glue and water, the present application only needs to be placed at the detection position, and then the upper top plate 211 is pressed down to complete water injection, sealing, horizontal detection, and water seepage detection. It is convenient to use and simple to operate.

[0038] It should be noted that the volume of capsule 1 221 needs to be larger than that of capsule 2 222 to meet the use requirements. When capsule 1 221 and capsule 2 222 are squeezed, in order to ensure that capsule 1 221 and capsule 2 222 move synchronously, the present application sets a limit frame 21 to drive capsule 1 221 and capsule 2 222 to move synchronously and reset. The limit frame 21 includes: an upper top plate 211 fixedly installed on both ends of capsule 1 221 and capsule 2 222, a lower bottom plate 212, a positioning rod 213 fixedly connected to the lower bottom plate 212, and a spring 214 wound on the positioning rod 213, and the two ends of the spring 214 are respectively fixedly connected to the upper top plate 211 and the lower bottom plate 212, and the positioning rod 213 is slidably connected to the upper top plate 211.

[0039] That is to say, under the action of the upper top plate 211, the capsule 1 221 and the capsule 2 222 are squeezed synchronously, which is more convenient to use. In addition, the spring 214 is deformed during squeezing. When the objects in the capsule 1 221 and the capsule 2 222 are discharged, the squeezing of the capsule 1 221 and the capsule 2 222 is stopped. The spring 214 is reset to drive the capsule 1 221 and the capsule 2 222 to reset, which is convenient for adding materials to the inside of the capsule 1 221 and the capsule 2 222. In addition, under the action of the positioning rod 213, the capsule 1 221 and the capsule 2 222 can be limited during the movement to avoid uneven compression of the capsule 1 221 and the capsule 2 222. In the actual detection process, it is only necessary to stand on the upper top plate 211 manually and rely on gravity to complete the foundation of the materials in the capsule 1 221 and the capsule 2 222. It is very convenient to use, and it is small in size and easy to carry.

[0040] As a further extension of the present application, a floating plate 121 is movably connected to the measuring cylinder 12, and a sensor 122 is fixedly installed on the floating plate 121 and the measuring cylinder 12. The sensor 122 is a capacitive proximity sensor. The measuring cylinder 12 is fixedly installed on the surface of the upper top plate 211. When water enters the measuring cylinder 12, the floating plate 121 floats up under the action of the water. At the same time, the distance between the sensor 122 on the floating plate 121 and the sensor 122 on the side wall of the measuring cylinder 12 approaches and moves away from each other in sequence, and an alarm is issued when they approach. On the one hand, the number of alarms of the sensor 122 reminds the staff of the amount of water inside the measuring cylinder 12. On the other hand, when water flows out of the measuring cylinder 12, the staff can be reminded of the amount of water outflow, so that the staff can have more accurate statistical results.

[0041] like Fig.12The sensors 122 shown are symmetrically and staggeredly arranged on the measuring cylinder 12 to avoid multiple sets of sensors 122 being installed on one side of the measuring cylinder 12, which would result in a large difference in structural strength on both sides of the measuring cylinder 12; that is, when the capsule 221 is squeezed, on the one hand, water enters the interior of the measuring cylinder 12 to prepare for detection, and on the other hand, the water pushes the float 121 to move inside the measuring cylinder 12, and an alarm is generated under the action of the sensor 122 to reflect the amount of water inside the measuring cylinder 12. The operation is simple and the use effect is good.

[0042] In addition, the cover plate 11 can also prevent foreign objects from affecting the floating plate 121, thereby preventing the floating plate 121 from being affected by foreign objects and causing the floating or movement of the floating plate 121 to be hindered, thereby affecting the alarm and reducing the accuracy of the detection result.
