[0025] like Figures 1 to 7As shown, the present invention provides a bridge health detection device 3, including a bridge pier 1, a fixing ring 2 is provided on the outside of the bridge pier 1, and the diameter of the fixing ring 2 is larger than that of the bridge pier 1. The fixing ring 2 is provided in two halves and fixed by means of screws, nuts and other structures. A traction rope 13 is passed through the fixing ring 2, and the traction rope 13 is fixedly connected to the fixing ring 2. The upper end of the traction rope 13 can be connected to a pulley, and the lower end is connected to a winding device to facilitate pulling the traction rope 13. A detection device 3 is connected to the inside of the fixing ring 2, and the detection device 3 has multiple detection devices evenly surrounding the inside of the fixing ring 2. The detection device 3 includes: a connecting rod 31, an irradiation lamp 32, a pushing device 33, a roller 37, a connecting tube 34, a segment resistor 35 and an electrical connecting piece 36. The connecting tube 34 is located on the inside of the fixing ring 2, and the interior of the connecting tube 34 is hollow. The connecting rod 31 passes through the connecting tube 34. It also passes through the fixed ring 2 and connects to the irradiation lamp 32. The middle portion of the connecting rod 31 is connected to a pusher 33, which comprises a sliding ring 331, a rotating wheel 332, and a second motor 333. The sliding ring 331 is located at the bottom of the glue-filling tube. The connecting rod passes through the sliding ring 331, and the second motor 333 is located inside the sliding ring 331. The output shaft of the second motor 333 is connected to the rotating wheel 332, which extends out of the sliding ring 331 on one side. Wiring or other devices can be installed inside the connecting rod 31 to electrically connect to the irradiation lamp 32. The lower portion of the connecting rod 31 is connected to an electrical connector 36, which has an arc-shaped surface near the segmented resistor 35. The segmented resistor 35 is located on the lower side of the connecting tube 34 and embedded in the inner wall of the tube. The segmented resistor 35 consists of multiple resistors arranged vertically, with the resistivity decreasing as it approaches the roller 37. The other end of the connecting rod 31 is connected to a roller 37, which is in rolling connection with the bridge pier 1. A support rod 5 is connected to the side of the fixing ring 2, and the support rod 5 is arranged at an angle. The support rod 5 is connected to a fixed block 8, which consists of two fixed blocks 8. A drive wheel 7 is rotatably connected between the two fixed blocks 8. A first motor 6 is rotatably connected to the outer side of the fixed block 8. The output shaft of the first motor 6 passes through the fixed block 8 and is connected to the drive wheel 7. The drive wheel 7 is connected to the outer side of the drive wheel 7 with anti-skid teeth 12, which are wedge-shaped.

[0026] The working principle of the above scheme is as follows: The two halves of the fixing ring 2 are placed around the outside of the bridge pier 1 and secured with screws. The first motor 6 is then activated to rotate the drive wheel 7, thereby moving the fixing ring 2. Simultaneously, the traction rope 13 is pulled to move the fixing ring 2. These two methods of moving the fixing ring 2 improve its stability. The pushing device 33 then pushes the connecting rod 31. When the pushing device 33 pushes, the second motor 333 rotates, driving the rotating wheel 332. The rotating wheel 332 clamps the connecting rod, allowing it to move up and down. This causes the roller 37 to roll against the bridge pier 1. When the roller 37 encounters a crack, it and the connecting rod 31 fall into the crack. As the electrical connector 36 moves downward, the protrusion 362 contacts the segmented resistor. The protrusion 362 then retracts and contacts the blocking piece 364, causing electrical connection to the illumination lamp 32, illuminating it. As the connecting rod 31 continues to move downward, the electrical connector 36 connects to the resistor with a lower resistivity, increasing the brightness of the illumination lamp 32. When it is necessary to continue driving, the pushing device 33 pulls the connecting rod 31 and the roller 37 back to reset. At this time, the fixing ring 2 continues to move. When different rollers 37 fall into different cracks, the arrangement and depth of the cracks can be observed from the external illumination lamp 32.

[0027] The beneficial effects of the above scheme are: through the illumination lamps 32 of multiple detection devices 3, the arrangement of cracks in the bridge pier 1 can be determined, which is convenient for manual recording of data; the depth of the cracks can be known by the brightness of the illumination lamps 32, which is convenient for manual judgment of the damage of the bridge pier 1.

[0028] In one embodiment of the present invention, Figures 1 to 4As shown, the fixing ring 2 is connected to a patching device 4, which has multiple components and is positioned corresponding to the detection device 3. The patching device 4 includes a glue injection cylinder 41, a pressure booster 42, a connecting block 43, a pressure sensor 44, a floating plate 45, and a glue outlet 46. One end of the glue injection cylinder 41 is located within the fixing ring 2, and the end of the glue injection cylinder 41 away from the connecting cylinder 34 defines a feed port 14. The other end of the glue injection cylinder 41 extends beyond the fixing ring 2 and communicates with the connecting cylinder 34. The lower end of the connecting cylinder 34 is connected to the glue outlet 46, which is conical in shape. Multiple connecting blocks 43 are arranged around the inner upper portion of the connecting cylinder 34. The electrical connector 36 defines a groove 47. A sidewall of the electrical connector defines a slide 361. A protrusion 362 is slidably connected to the slide 361. A spring 363 is connected between the protrusion 362 and the slide 361. A stopper 364 is connected within the slide 361. There are multiple grooves 47, corresponding to the connection blocks 43. The lower end of the connecting rod 31 is connected to the pressure sensor 44. Two floating plates 45 are located at the lower end of the connecting rod 31 and are hinged to the connecting rod 31. A collection ring 9 is slidably connected to the outside of the pier 1, with one side of the collection ring 9 being open. The interior of the collection ring 9 is hollow, with the side of the collection ring 9 near the pier 1 being wedge-shaped and the other side being funnel-shaped. The collection ring 9 is connected to a collection pipe 10, one end of which is connected to a storage tank 11.

[0029] The above scheme works as follows: When roller 37 and connecting rod 31 fall into the crack, electrical connector 36 descends, groove 47 no longer aligns with connecting block 43, and the glue liquid is pressurized by booster device 42, causing it to flow out of groove 47 through glue outlet 46 and into the crack. When the glue liquid fills the crack, the buoyancy of float plate 45 drives connecting rod 31 upward. When the float plate emerges from the crack, pressure sensor 44 is no longer under pressure and sends a signal to push device 33, which drives connecting rod 31 upward, causing roller 37 to clear the crack. At this point, groove 47 aligns with connecting block 43, and glue liquid no longer flows out. Roller 37 is now outside the crack, and illumination lamp 32 stops emitting light. The first motor 6 is then controlled to rotate, causing fixed ring 2 to move, and push device 33 again moves connecting rod 31 downward. The glue liquid on the outside of pier 1 is scraped off by collection ring 9 and enters storage tank 11.

[0030] The beneficial effects of the above scheme are as follows: the cracks can be repaired by filling glue through the seam filling device 4 to prevent the cracks from further deteriorating; the excess glue can be collected by the collection ring 9 and the storage tank 11 to avoid glue waste.

[0031] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
