[0028] like Figures 1 to 9As shown, the road bridge health monitoring device based on artificial intelligence of the present invention includes a bridge pier, and the outer side of the bridge pier 1 is fixedly covered with a fixed shell 2, and the upper part of the fixed shell 2 is arranged obliquely to prevent rainwater accumulation. A support frame 5 is connected between the fixed shell 2 and the bridge pier 1, which is used to reinforce the connection of the fixed shell 2. A plurality of detection devices 3 for detecting cracking and deformation of the bridge pier 1 are connected inside the fixed shell 2, and the detection device 3 includes: a resistance rod 33, an outer cylinder 34, a first spring 35, a bump 36, a second spring 39, a first electrical connection piece 310, a second electrical connection piece 38, a fixed groove 31, a connecting rod 311 and a warning light 32. The fixed groove 31 is fixedly connected to the outer side of the fixed shell 2, and the outer cylinder 34 passes through the fixed shell 2 and the fixed groove 31 and is slidably connected thereto, and the outer cylinder 34 can slide in the fixed groove 31. The fixing groove 31 is connected with a baffle 8, the outer tube 34 is fixedly connected with the baffle 8, and a fourth spring 7 is connected between the baffle 8 and the fixing groove 31, and the fourth spring 7 is used to prevent the outer tube 34 from excessive displacement. The outer tube 34 is hollow, and one end of the abutment rod 33 is slidably connected with the outer tube 34, and the abutment rod 33 slides in the outer tube 34. The side of the abutment rod 33 close to the outer tube 34 is in an arc shape, and the end of the protrusion 36 close to the abutment rod 33 is in an arc shape, so that when the abutment rod 33 contacts the protrusion 36, the protrusion 36 is forced to retract into the groove 37. The other end of the abutment rod 33 is connected with a resisting plate 9, one end of the resisting plate 9 contacts the bridge pier 1, and the side of the resisting plate 9 close to the bridge pier 1 is in an arc shape to fit the bridge pier 1. The abutment rod 33 passes through the first spring 35, and the first spring 35 is located between the outer tube 34 and the bridge pier 1, so that the abutment rod 33 can be reset after being forced. The inner wall of the outer tube 34 is provided with a groove 37, the first electrical connection piece 310 is disposed in the groove 37 and fixedly connected to the groove 37, and the second electrical connection piece 38 is slidably connected to the groove 37. One end of the protrusion 36 is located in the groove 37 and slidably connected to the groove 37, and the other end of the protrusion 36 extends out of the groove 37. The second spring 39 is located between the second electrical connection piece 38 and the protrusion 36, and one end of the outer tube 34 close to the fixed groove 31 is fixedly connected to the connecting rod 311, one end of the connecting rod 311 passes through the fixed groove 31 and is slidably connected to the fixed groove 31, and the connecting rod 311 is connected to the warning light 32, and the warning light 32 is electrically connected to the first electrical connection piece 310.

[0029] The working principle of the above scheme is as follows: when the bridge pier 1 is deformed and cracked, one side of the bridge pier 1 moves toward the abutment rod 33, and the abutment rod 33 is forced to move toward the outer tube 34. One end of the abutment rod 33 slides in the outer tube 34, and the abutment rod 33 abuts against the protrusion 36. The protrusion 36 is forced to drive the second electrical connection piece 38 upward, so that the second electrical connection piece 38 is electrically connected to the first electrical connection piece 310, and the warning light 32 lights up to send a warning signal. When the abutment rod 33 continues to move toward the outer tube 34, the outer tube 34 is forced to drive the baffle 8 and the connecting rod 311 to move toward the warning light 32, and the fourth spring 7 is compressed to reduce the pressure of the outer tube 34.

[0030] The beneficial effects of the above scheme are as follows: when the bridge pier 1 is cracked and deformed, the warning light 32 is turned on by the detection device 3 to send an electrical signal to the staff, so that people can know the lesions of the bridge pier 1 at the first time; the cracking and deformation of the bridge pier 1 causes the resistance rod 33 to move under force, and the movement of the resistance rod 33 causes the protrusion 36 to move upward, and the protrusion 36 drives the first electrical connecting piece 310 to move and contact the second electrical connecting piece 38, so that the warning light 32 is electrically connected, and the warning light 32 sends out an alarm signal.

[0031] In one embodiment of the present invention, Figures 1 to 4 As shown, the upper part of the fixed shell 2 is connected with a protective device 4 for protecting the detection device 3 and detecting fragments, and the protective device 4 includes: a protective plate 41, a fixed plate 42, a third spring 44, a fixed rod 43, a third electrical connection sheet 46, a resistor 45 and an alarm 47. The protective plate 41 is coated on the outer side of the pier 1 and is slidably connected to the pier 1. The upper part of the protective plate 41 is arranged obliquely to facilitate the sliding of rainwater. The fixed plate 42 is fixedly connected to the upper part of the fixed shell 2. The protective plate 41 is provided with a slide groove 6. The fixed rod 43 passes through the slide groove 6 and is slidably connected to the slide groove 6. The fixed rod 43 slides in the slide groove 6. The third spring 44 is coated on the outer side of the fixed rod 43. The third spring 44 is located between the protective plate 41 and the fixed plate 42. The third spring 44 plays a role of unloading. The resistor 45 is located in the slide groove 6. The third electrical connection sheet 46 is connected to the fixed rod 43. The third electrical connection sheet 46 can be electrically connected to the resistor 45. The alarm 47 is fixedly connected to the lower side of the protection plate 41, and is electrically connected to the resistor sheet 45. The resistor sheet 45 is connected to the third electrical connection sheet 46 to energize the alarm 47. The resistor sheet 45 is formed by connecting a plurality of resistors of different thicknesses, and the resistor sheet 45 becomes thinner from top to bottom, so that the alarm 47 sends different signals when the third electrical connection sheet 46 is connected to different resistor sheets 45.

[0032] The working principle of the above scheme is as follows: when the bridge pier 1 is cracked and gravel is peeled off, the gravel falls onto the protective plate 41, and the protective plate 41 is forced to move downward, and the third spring 44 is compressed. At this time, the third connecting piece slides in the slide groove 6 and connects with the resistor 45, and the alarm 47 is connected and an alarm is sounded. When too much gravel continues to exert pressure on the protective plate 41, the protective plate 41 continues to move downward, and the third electrical connecting piece 46 contacts the thinner resistor 45, and the alarm 47 is able to send out an alarm signal of a different signal.

[0033] The beneficial effects of the above scheme are as follows: the protective device 4 prevents the fragments from damaging the detection device 3 when the pier 1 cracks and peels off; when the fragments fall onto the protective plate 41 through the protective device 4, the protective plate 41 moves downward to electrically connect the third electrical connecting piece 46 with the resistor 45, and the alarm 47 sounds an alarm; when the protective plate 41 moves downward, the third electrical connecting piece 46 is connected to resistors 45 of different thicknesses, so that the alarm 47 sends out different electrical signals, so that people can know the amount of fragments that have fallen and thus the degree of damage to the pier 1.

[0034] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. 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.
