Description

Technical Field

[0001] The present application relates to the technical field of roads and bridges, and in particular to a road and bridge water seepage detection device. Background Art

[0002] Bridge engineering refers to the process of bridge survey, design, construction, maintenance and verification, as well as the science and engineering technology that studies this process. It is a branch of civil engineering. After the construction of a bridge is completed, it needs to be tested for water seepage. The existing road bridge water seepage detection device is that the staff cleans the dust on the road surface after the construction is completed, and then samples the local inspection points on the road surface. Then the staff applies gypsum powder on the smooth road surface, and then presses the bottom of the detector on the top of the gypsum powder to stick it. Finally, the staff injects water into the measuring cylinder to observe the water level drop, so as to detect the water seepage of the road beam bridge. After the inspection of the inspection point is completed, the staff then goes to the next point for inspection, and repeats this process until all the inspection points are inspected.

[0003] The above-mentioned existing technical solutions have the following defects: since roads and bridges need to be tested for water seepage at multiple locations, workers take a detection device and repeat an action detection on the road surface sampling points. This process consumes a huge amount of working time and physical strength of the workers, resulting in low work efficiency of the workers during the inspection process. Summary of the invention

[0004] In order to make road and bridge water seepage detection more convenient, the present application provides a road and bridge water seepage detection device.

[0005] The above technical objectives of this application are achieved through the following technical solutions:

[0006] The road bridge water seepage detection device comprises a frame, a detection measuring cylinder is arranged above the frame, a first sealing ring for sealing is arranged at the lower end of the detection measuring cylinder, the detection measuring cylinder is connected to a lifting structure for automatically driving the detection measuring cylinder to move up and down, and a water supply structure for supplying water to the detection measuring cylinder is arranged above the frame.

[0007] By adopting the above scheme, when conducting water seepage detection on roads and bridges, the vehicle frame is pushed to the position to be detected, and then the detection cylinder is driven downward by the lifting structure until the first sealing ring is tightly attached to the ground, thereby sealing the measuring position, and then the water supply structure supplies water to the detection cylinder, and then the operator observes the change in the water amount in the detection cylinder, thereby realizing automatic water seepage detection on roads and bridges more conveniently.

[0008] Optionally, the lifting structure includes a motor and a rotating ring. A detection hole is opened above the frame, a support tube is fixedly arranged above the detection hole, the rotating ring is rotatably connected above the support tube, gear teeth are arranged on the outer side of the rotating ring, and an internal thread is arranged on the inner side of the rotating ring. The motor is arranged on the frame, and the motor output shaft is connected to a lifting gear, the lifting gear is meshed with the gear teeth on the outer side of the rotating ring, a threaded sleeve is fixedly arranged on the outer circumferential surface of the detection cylinder, an external thread is arranged on the outer side of the threaded sleeve, and the detection cylinder is connected to a limiting structure for preventing the detection cylinder from rotating.

[0009] By adopting the above technical solution, when it is necessary to conduct water seepage detection on roads and bridges, the motor drives the lifting gear to rotate, and the lifting gear drives the rotating ring to rotate, thereby driving the threaded sleeve and the detection cylinder to move downward, and the limit structure limits the rotation of the detection cylinder. Similarly, after the detection is completed, the motor reverses and drives the detection cylinder to move upward, thereby completing the lifting and lowering of the lifting cylinder.

[0010] Optionally, the limiting structure includes a limiting bracket, a plurality of rollers are connected to the circumferential surface of the limiting bracket, the axes of the rollers are horizontal, and a vertical slide groove is opened on the inner wall of the support tube opposite to the rollers, and the rollers roll along the slide groove.

[0011] By adopting the above technical solution, the roller can only move up and down along the slide groove, so that the detection cylinder can only move up and down, and the rolling of the roller reduces the friction between the inner wall of the support tube and the limit bracket, so that the limit bracket moves more smoothly along the slide groove.

[0012] Optionally, a gypsum box for containing gypsum powder is provided above the frame, and a conduit is connected below the gypsum box. The end of the conduit facing away from the gypsum box is connected to the inner surface of the support tube, and a cylindrical sealing tube is slidably connected in the support tube. A second sealing ring is provided below the sealing tube, and the sealing tube is connected to a clamping structure for limiting the falling of the sealing tube. A gypsum channel is provided in the annular wall of the sealing tube, and the gypsum channel spirals downward in the sealing tube, and a plurality of through holes are provided below the inner surface of the sealing tube, and the through holes connect the inner wall of the sealing tube with the gypsum channel, and the gypsum channel is connected to the outer wall of the sealing tube at the upper end. When the second sealing ring contacts the ground, the end of the conduit facing away from the gypsum box is opposite to the connection between the gypsum channel and the outer surface of the sealing tube.

[0013] By adopting the above technical solution, when the first sealing ring reaches the ground, the clamping structure releases the fixation of the sealing tube, causing the sealing tube to fall to the ground, so that the second sealing ring is close to the ground, and a cavity is formed between the second sealing ring and the first sealing ring. At the same time, the gypsum powder enters the gypsum channel along the conduit and flows into the space between the first sealing ring and the second sealing ring from the through hole, thereby sealing the edge of the first sealing ring, thereby further strengthening the sealing of the sealing ring.

[0014] Optionally, the snap connection structure includes a snap pin and a snap spring. A snap cavity is formed on the inner side of the annular tube wall of the support tube. A pin hole communicating the inner surface of the support tube with the snap cavity is formed on the inner surface of the support tube. An unlocking hole is formed above the pin hole. The unlocking hole and the pin hole are respectively located at the upper position and the lower position of the snap cavity. The snap pin is in a "C" shape. The upper part of the snap pin is slidably connected in the unlocking hole, and the upper end of the snap pin is inclined with an upward slope. The lower part of the snap pin is slidably connected in the pin hole, and the lower end of the snap pin is inclined with a downward slope. The snap spring is located in the snap cavity. One end of the snap spring is fixedly connected to the inner wall of the snap cavity, and the other end of the snap spring is fixedly connected to the snap pin. A clamping groove is formed on the outer surface of the sealing tube. The lower end of the snap pin is inserted into the clamping groove. When the detection measuring cylinder descends to the lowest position, the limiting structure presses the upper end of the snap pin completely into the unlocking hole. A push rod is fixedly arranged on the inner surface of the sealing tube, and the push rod is located above the first sealing ring. A top ring is fixedly arranged on the outer circumferential surface at the lower position of the detection measuring cylinder.

[0015] By adopting the above technical solution, when the first sealing ring contacts the ground, the limiting structure presses the snap pin into the unlocking hole, causing the snap pin to slide out of the clamping groove, thereby releasing the fixation of the sealing tube. As a result, the sealing tube falls under the influence of gravity. When the first sealing ring moves upward, the top ring abuts against the lower part of the push rod, thereby driving the push rod and the sealing tube to move upward. Thus, the sealing tube presses the snap pin into the pin hole until the pin hole is aligned with the clamping groove, and the snap pin is inserted into the clamping groove, thereby fixing the sealing tube again.

[0016] Optionally, two detection measuring cylinders are provided, and both detection measuring cylinders are connected to the lifting structure.

[0017] By adopting the above technical solution, two groups of data can be detected simultaneously during the water seepage detection, so as to form a comparison and reduce the measurement error.

[0018] Optionally, the detection measuring cylinder is connected with an air extraction structure for extracting the air in the measuring cylinder.

[0019] By adopting the above technical solution, the air in the detection measuring cylinder is extracted, so that the atmospheric pressure presses the first sealing ring tightly against the ground, thereby strengthening the sealing of the detection measuring cylinder and making the detection result more accurate.

[0020] Optionally, the air extraction structure includes an air suction fan and an air extraction pipe. One end of the air extraction pipe is connected to the air suction fan, and the other end is communicated with the inside of the detection measuring cylinder. An upper baffle and a lower baffle are hinged in the detection measuring cylinder. The water supply structure is communicated with the upper part of the detection measuring cylinder. The upper baffle is arranged between the connection of the detection measuring cylinder and the water supply structure and the connection of the detection measuring cylinder and the air extraction pipe. The lower baffle is arranged between the connection of the detection measuring cylinder and the air extraction pipe and the first sealing ring. The detection measuring cylinder is connected with a control structure for controlling the opening and closing of the upper baffle and the lower baffle.

[0021] By adopting the above technical solution, when it is necessary to detect water seepage on roads and bridges, first press the first sealing ring against the ground through the lifting structure, then close the upper baffle, open the lower baffle, and then evacuate the detection cylinder to make the first sealing ring more tightly pressed against the ground. Then close the lower baffle, open the upper baffle, and then supply water to the detection cylinder through the water supply structure. After the water supply is completed, close the upper baffle and open the lower baffle. Only the water used for detection falls into the first sealing ring. At the same time, since the upper baffle is closed, the detection cylinder is in a sealed state. Then, the water seepage performance of the road and bridge is detected by observing the change in water level.

[0022] Optionally, the control structure includes a walking cylinder, an upper torsion spring and a lower torsion spring, one end of the upper torsion spring is connected to the upper baffle, and the other end of the upper torsion spring is connected to the detection measuring cylinder. When the upper torsion spring is at its original length, the upper baffle is in a closed state, one end of the lower torsion spring is connected to the lower baffle, and the other end of the lower torsion spring is connected to the detection measuring cylinder. When the lower torsion spring is at its original length, the lower baffle is in a closed state, one end of the hinge shaft of the upper baffle passes through the detection measuring cylinder and is fixedly connected to the upper gear, one end of the hinge shaft of the lower baffle passes through the detection measuring cylinder and is fixedly connected to the lower gear, the walking cylinder is arranged on the outside of the detection measuring cylinder, the walking cylinder moves vertically along the outer wall of the detection measuring cylinder, the walking cylinder is fixedly connected to a rack, when the walking cylinder moves to the upper gear, the rack meshes with the upper gear, and when the walking cylinder moves to the lower gear, the rack meshes with the lower rack.

[0023] By adopting the above technical solution, when it is necessary to evacuate the detection measuring cylinder, the walking cylinder is located at the bottom, at which time the upper baffle is in a closed state and the lower baffle is in an open state. When the air is evacuated, the walking cylinder moves upward, the lower torsion spring rebounds to drive the lower baffle to close, the upper gear and the rack engage to drive the upper baffle to open, and then the water supply structure supplies water to the detection measuring cylinder. After the water supply is completed, the walking cylinder moves downward, the upper torsion spring rebounds to drive the upper baffle to close, the lower gear and the rack engage to drive the lower baffle to open, thereby preventing gas from entering the first sealing ring during water supply, causing the sealing of the first sealing ring to be weakened.

[0024] Optionally, the upper baffle is connected to an upper sealing ring for strengthening the sealing of the upper baffle, and the lower baffle is connected to a lower sealing ring for strengthening the sealing of the lower baffle.

[0025] By adopting the above technical solution, the sealing of the upper baffle and the lower baffle is increased, so that the detection result of the detection device is more accurate.

[0026] In summary, this application has the following technical effects:

[0027] 1. By setting up a water supply structure and a lifting structure, the device can automatically detect water seepage on roads and bridges;

[0028] 2. The air extraction structure is provided to make the first sealing ring fit more closely to the ground, thereby improving the sealing effect of the first sealing ring;

[0029] 3. The sealing of the detection device is further strengthened by providing a sealing tube and a second sealing ring. BRIEF DESCRIPTION OF THE DRAWINGS

When it is necessary to conduct a road and bridge water seepage detection, the frame 1 is pushed to the road surface to be detected, and then the two detection measuring cylinders 2 are driven downward by the lifting structure 4, so that the first sealing ring 3 is close to the ground, so that the first sealing ring 3 seals the gap between the detection measuring cylinder 2 and the ground, and then water is supplied to the detection measuring cylinder 2 through the water supply structure 6, and the operator detects the water seepage performance of the road and bridge by observing the water level change in the detection measuring cylinder 2.

[0039] Reference Figure 1 The water supply structure 6 includes a water tank 61 and a water pipe 63. The water tank 61 is arranged above the frame 1. A water pump is arranged inside the water tank 61. One end of the water pipe 63 is connected to the water pump. The other end of the water pipe 63 is divided into two sections. The two sections of the water pipe 63 are respectively connected to the top of the two detection cylinders 2.

[0040] Reference Figure 1 , Figure 2 as well as Figure 3The lifting structure 4 includes a motor 41 and a rotating ring 42. Two detection holes 11 are opened on the frame 1. A support tube 5 is fixedly connected just above the detection hole 11. The rotating ring 42 is rotatably connected above the support tube 5. The outer wall of the rotating ring 42 is provided with gear teeth. The motor 41 is fixedly arranged above the frame 1. The output shaft of the motor 41 is vertically upward, and the output shaft of the motor 41 is fixedly connected with a lifting gear 411. The lifting gear 411 is meshed with the gear teeth of the two rotating rings 42 at the same time. An internal thread is provided on the inner side of the rotating ring 42, a threaded sleeve 421 is fixedly provided on the outer side of the detection measuring cylinder 2, an external thread is provided on the outer side of the threaded sleeve 421, the threaded sleeve 421 is connected to the inner side of the rotating ring 42 through threads, a limit bracket 423 for limiting the rotation of the detection measuring cylinder 2 is fixedly connected below the detection measuring cylinder 2, a plurality of vertical slide grooves 51 are provided inside the support tube 5, a roller 4231 is provided at the position of the limit bracket 423 facing the slide groove 51, and the roller 4231 rolls in the slide groove 51. When the detection cylinder 2 needs to be lowered, the motor 41 drives the lifting gear 411 to rotate, thereby driving the rotating ring 42 to rotate, and the rotating ring 42 is threadedly connected to the threaded sleeve 421, so the rotating ring 42 rotates to drive the threaded sleeve 421 and the detection cylinder 2 to move downward, and the roller 4231 slides in the slide groove 51 to limit the rotation of the detection cylinder 2, so that the detection cylinder 2 can only move in the vertical direction, and the roller 4231 can reduce the friction between the limit bracket 423 and the support tube 5, so that the detection cylinder 2 can be lowered more smoothly until the detection cylinder 2 drops to the lowest position. When the detection cylinder 2 needs to be raised, similarly, the motor 41 reverses, thereby driving the rotating ring 42 to rotate, thereby driving the detection cylinder 2 to move upward.

[0041] Reference Figure 1 and Figure 2A gypsum box 12 for containing gypsum powder is fixedly connected above the frame 1, and a conduit 121 is connected below the gypsum box 12. The end of the conduit 121 away from the gypsum box 12 penetrates the support tube 5 to reach the inside of the support tube 5. A fan 122 is arranged above the frame 1 near the support tube 5, and the air outlet of the fan 122 is connected to the conduit 121. An electric valve is arranged in the gypsum box 12. A sealing tube 13 is slidably connected at a lower position inside the support tube 5, and a second sealing ring 131 is fixedly arranged below the sealing tube 13. The sealing tube 13 is sleeved on the outside of the detection measuring cylinder 2, and a gypsum channel 132 is provided on the inner side of the annular wall of the sealing tube 13. The gypsum channel 132 is spiral, and a plurality of through holes 133 connected to the inner wall of the sealing tube 13 are provided at a lower position of the gypsum channel 132. The plurality of through holes 133 surround the sealing tube 13. The gypsum channel 132 is connected to the outside of the side wall of the sealing tube 13 at the upper end, and when the sealing tube 13 slides to the lowest point, one end of the conduit 121 is connected to the gypsum channel 132, and the sealing tube 13 is connected to a clamping structure for limiting the falling of the sealing tube 13. When conducting water seepage detection on roads and bridges, the detection measuring cylinder 2 moves downward until the first sealing ring 3 is in close contact with the ground, and then the clamping structure releases the restriction on the sealing tube 13, so that the sealing tube 13 moves downward under the influence of gravity, so that the second sealing ring 131 is in close contact with the ground, the conduit 121 is connected with the gypsum channel 132, the fan 122 is started, and then the electric valve is opened, and the gypsum powder enters the gypsum channel 132. The fan 122 enables the gypsum powder to move smoothly along the gypsum channel 132 and flow into the cavity between the first sealing ring 3 and the second sealing ring 131 at the through hole 133, so that the edge of the first sealing ring 3 is sealed with gypsum powder, so that the small gap between the first sealing ring 3 and the ground is blocked, so that the sealing performance of the first sealing ring 3 is better, so that the detection result is more accurate.

[0042] Reference Figure 2 and Figure 4, the clamping structure includes a clamping pin 53 and a clamping spring 54. A clamping cavity 52 is formed inside the annular wall of the support pipe 5. The clamping cavity 52 is provided with an unlocking hole 522 and a pin hole 521 that communicate with the inner wall of the support pipe 5 on the side close to the inner wall of the support pipe 5. The pin hole 521 is located at the lower position of the clamping cavity 52, and the unlocking hole 522 is located at the upper position of the clamping cavity 52, and the unlocking hole 522 is located within the sliding groove 51. The clamping pin 53 is arranged inside the clamping cavity 52. The clamping pin 53 is in a "C" shape, and the upper part of the clamping pin 53 is slidably connected inside the unlocking hole 522, and the lower part of the clamping pin 53 is slidably connected inside the pin hole 521. One end of the upper part of the clamping pin 53 is inclined with the slope facing upwards, and one end of the lower part of the clamping pin 53 is inclined with the slope facing downwards. The clamping spring 54 is located inside the clamping cavity 52. One end of the clamping spring 54 is fixedly connected to the inner wall of the clamping cavity 52, and the other end of the clamping spring 54 is fixedly connected to the clamping pin 53. When the spring is in its original length, one end of the upper part and one end of the lower part of the clamping pin 53 respectively extend out of the unlocking hole 522 and the pin hole 521. A clamping groove 134 is formed on the outer side wall of the sealing pipe 13, and one end of the lower part of the clamping pin 53 is inserted into the clamping groove 134. When the detection measuring cylinder 2 descends, the roller 4231 rolls inside the sliding groove 51. When the detection measuring cylinder 2 descends to the lowest position, the roller 4231 comes into contact with the slope of one end of the upper part of the clamping pin 53 and presses one end of the upper part of the clamping pin 53 into the unlocking hole 522, thereby driving the lower end of the clamping pin 53 to slide out of the clamping groove 134, and simultaneously compressing the clamping spring 54, causing the sealing pipe 13 to fall under the influence of gravity, so that the second sealing ring 131 is close to the ground, facilitating the putting of gypsum powder between the first sealing ring 3 and the second sealing ring 131.

[0043] Refer to Figure 2 , a push rod 55 is fixedly connected to the lower position of the sealing pipe 13, and a top ring 21 is provided on the outer circumferential surface of the lower position of the detection measuring cylinder 2. The push rod 55 is located above the top ring 21. After the detection of road and bridge water seepage is completed, the detection measuring cylinder 2 moves upwards, causing the top ring 21 to abut against the lower part of the push rod 55, thereby driving the push rod 55 and the first sealing ring 3 to move upwards, causing the detection measuring cylinder 2 to press the lower end of the clamping pin 53 into the pin hole 521. When the pin hole 521 is aligned with the clamping groove 134, the clamping spring 54 rebounds and inserts the lower end of the clamping pin 53 into the clamping groove 134, thereby fixing the sealing pipe 13 for convenient use next time.

[0044] Refer to Figure 1 Figure 5 and Figure 6The detection measuring cylinder 2 is connected to an exhaust structure 8, and the exhaust structure 8 includes an air suction fan 81 and an exhaust pipe 82. The air suction fan 81 is fixedly arranged above the frame 1, one end of the exhaust pipe 82 is connected to the air suction fan 81, and the other end of the exhaust pipe 82 is connected to the detection measuring cylinder 2. An upper boss 832 and a lower boss 842 are fixedly arranged in the detection measuring cylinder 2. The connection between the exhaust pipe 82 and the detection measuring cylinder 2 is located between the upper boss 832 and the lower boss 842. An upper baffle 83 is arranged below the upper boss 832. The upper baffle 83 is hinged to the detection measuring cylinder 2, and an upper sealing ring 831 is arranged on the edge of the upper baffle 83. A lower baffle 84 is arranged above the lower boss 842, the lower baffle 84 is hinged to the detection measuring cylinder 2, and a lower sealing ring 841 is arranged on the edge of the lower baffle 84, the upper baffle and the lower baffle 84 are connected with a control structure 9, and the upper baffle 83 and the lower baffle 84 are linked through the control structure 9. After the detection measuring cylinder 2 is lowered to the lowest point, the control structure 9 closes the upper baffle 83 and opens the lower baffle 84, and then starts the suction fan 81 to exhaust air in the detection measuring cylinder 2 to reduce the air pressure in the detection measuring cylinder 2. The atmospheric pressure makes the first sealing ring 3 stick more closely to the ground, thereby strengthening the sealing of the first sealing ring 3. Then the control structure 9 closes the lower baffle 84 and opens the upper baffle 83 to seal between the first sealing ring 3 and the lower baffle 84. Then water is added to the detection measuring cylinder 2 through the water pipe 63. After the water is added, the control structure 9 drives the upper baffle 83 to close and the lower baffle 84 to open, thereby preventing gas from entering the detection measuring cylinder 2 during the water addition process, causing the sealing effect of the first sealing ring 3 to weaken. Then the water level in the detection measuring cylinder 2 is observed to detect water seepage in the road bridge.

[0045] Reference Figure 5 and Figure 6The control structure 9 includes a travel cylinder 91, an upper torsion spring 92 and a lower torsion spring 93. The upper torsion spring 92 is sleeved on the outer side of the hinge shaft of the upper baffle 83. When the upper torsion spring 92 is in a normal state, the upper baffle 83 is in a closed state. One end of the hinge shaft of the upper baffle 83 passes through the detection cylinder 2 and is fixedly connected to the upper gear 921. The lower torsion spring 93 is sleeved on the outer side of the hinge shaft of the lower baffle 84. When the lower torsion spring 93 is in a normal state, the lower baffle 84 is in a closed state. One end of the hinge shaft of the lower baffle 84 passes through the detection cylinder 2 and is fixedly connected to the lower gear 931. The traveling cylinder 91 is arranged on the outside of the detection measuring cylinder 2, and the traveling cylinder 91 can move back and forth between the upper baffle 83 and the lower baffle 84. The traveling cylinder 91 is fixedly connected with a rack 911. When the traveling cylinder 91 moves from bottom to top to the position of the upper baffle 83, the upper gear 921 is engaged with the rack 911, and the upper gear 921 rotates to drive the upper baffle 83 to open; when the traveling cylinder 91 moves to the position of the lower baffle 84, the lower gear 931 is engaged with the rack 911, and the lower gear 931 rotates to drive the lower baffle 84 to open. When it is necessary to pump air, the walking cylinder 91 is located at the lower baffle 84, so that the upper baffle 83 is closed and the lower baffle 84 is opened; when it is necessary to supply water to the detection measuring cylinder 2, the walking cylinder 91 moves upward, the lower torsion spring 93 rebounds to drive the lower baffle 84 to close, and then the walking cylinder 91 reaches the upper baffle 83, so that the upper rack 911 drives the upper gear 921 to rotate, thereby driving the upper baffle 83 to open; when the water supply is completed, the walking cylinder 91 moves downward, the upper torsion spring 92 rebounds to drive the upper baffle 83 to close, and then the walking cylinder 91 reaches the lower baffle 84, so that the lower rack 911 drives the lower gear 931 to rotate, thereby driving the lower baffle 84 to open.

[0046] The specific implementation principle of the present application is as follows: when it is necessary to conduct water seepage detection of road bridges, the frame 1 is pushed to the place where detection is required, and then the motor 41 drives the lifting gear 411 to rotate, thereby driving the two rotating rings 42 to rotate, thereby driving the detection cylinder 2 to move downward, and the roller 4231 slides in the slide groove 51, thereby limiting the rotation of the detection cylinder 2. When the detection cylinder 2 drops to the lowest position, the first sealing ring 3 is in close contact with the ground, and at the same time, the roller 4231 presses the card pin 53 into the unlocking hole 522, so that the card pin 53 slides out of the card groove 134, so that the sealing tube 13 moves downward under the influence of gravity, so that the second sealing ring 131 is in close contact with the ground. Then the conduit 121 is connected with the gypsum channel 132, so that the gypsum powder enters the inside of the gypsum channel 132 and flows out from the through hole 133, so that the gypsum powder blocks the tiny gap between the first sealing ring 3 and the ground, so that the sealing effect of the first sealing ring 3 is better. The travel cylinder 91 moves downward, the upper torsion spring 92 rebounds to drive the upper baffle 83 to close, the rack 911 engages with the lower gear 931 to open the lower baffle 84, and then the suction fan 81 simultaneously evacuates air from the two detection measuring cylinders 2 to reduce the air pressure in the detection measuring cylinders 2, so that the atmospheric pressure can press the first sealing ring 3 more tightly to the ground, thereby improving the sealing effect of the first sealing ring 3. Then the travel cylinder 91 moves upward, the lower torsion spring 93 rebounds and drives the lower baffle 84 to close, so that a closed cavity is formed between the lower baffle 84 and the first sealing ring 3, and the rack 911 drives the upper gear 921 to rotate, thereby opening the upper baffle 83, and then the water pump supplies water to the detection measuring cylinder 2 through the water pipe 63 to prevent gas from entering during the water adding process and causing the sealing effect of the first sealing ring 3 to be weakened, and then the travel cylinder 91 moves downward, the upper spring rebounds and drives the upper baffle 83 to close, and the rack 911 drives the lower gear 931 to rotate, thereby driving the lower baffle 84 to open, so that water contacts the ground, thereby detecting the road bridge deck.

[0047] This specific embodiment is merely an explanation of the present application and is not a limitation of the present application. After reading this specification, those skilled in the art may make modifications to the present embodiment without any creative contribution as needed, but such modifications are protected by the patent law as long as they are within the scope of the claims of the present application.
