[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0029] Please see Figures 1-8One embodiment of the present invention is: a sensor-based bridge steel structure fillet weld inspection device, comprising a device body 1, a temperature sensor 2 disposed on the front of the device body 1, a humidity sensor 3 disposed at the center of the front of the device body 1, and further comprising an anti-blurring device 4 and an anti-short-circuit device 5. The anti-blurring device 4 is disposed on the top of the device body 1, and the anti-short-circuit device 5 is disposed inside the anti-blurring device 4. The anti-blurring device 4 comprises a display component 41, a detection component 42, and a locking block 43. The bottom of the display component 41 is fixedly installed on the top of the device body 1. The bottom of the detection component 42 is fixedly connected to the front of the display component 41 by a connecting wire, and the connecting wire is elastic. The back of the locking block 43 is fixedly installed on the front of the display component 41, and the locking block 43 fits into the detection component 42. When the display component 41 and the detection component 42 are activated, the operator holds the detection component 42 to measure the weld. The data is displayed on the screen in the display component 41. The detection component 42 fits into the locking block 43, preventing the detection component 42 from being placed randomly when stationary, thus avoiding the possibility of damage.

[0030] The anti-blurring device 4 also includes a baffle plate 44, a retractable frame 45, an adhesive wheel 46, and a spring 47. The top right side of the baffle plate 44 is hinged to the left side of the display assembly 41. The left outer wall of the retractable frame 45 passes through and is hinged inside the baffle plate 44. The adhesive wheel 46 passes through and is rotatably mounted on the right outer wall of the retractable frame 45, and the outer wall of the adhesive wheel 46 contacts the display screen in the display assembly 41. A groove is formed on the outer wall of the adhesive wheel 46. The right side of the spring 47 is fixedly mounted on the inner wall of the groove of the adhesive wheel 46. When the detection work begins, the baffle plate 44 is opened. When stationary, the baffle 44 protects the display screen from damage. When the baffle 44 flips upward, it drives the retractable frame 45 to move downward. The retractable frame 45 drives the adhesion wheel 46 to slide synchronously along the outer wall of the display screen. Due to frictional resistance, the adhesion wheel 46 starts to rotate, which improves the removal effect of the adhesion wheel 46 on the surface of the display screen. The adhesion wheel 46 drives the spring 47 to rotate and squeeze the display screen to deform. When the spring 47 deforms, it expands the adhesion range of the adhesion wheel 46 on the original basis and improves the removal effect.

[0031] The short-circuit protection device 5 includes an electrically telescopic rotating column 51, a heating plate 52, and a convex ball rod 53. The back of the electrically telescopic rotating column 51 is rotatably mounted on the back of the inner wall of the display component 41, and an arc-shaped groove is provided on the outer wall of the electrically telescopic rotating column 51. The back of the heating plate 52 is fixedly mounted on the front of the telescopic end of the electrically telescopic rotating column 51, and the back of the convex ball rod 53 is fixedly mounted on the front of the heating plate 52, with the convex ball in the convex ball rod 53 being rotatably mounted. When the electrically telescopic rotating column 51 is activated, it rotates intermittently. The telescopic end of the electrically telescopic rotating column 51 drives the heating plate 52 to move left and right and rotate. The heating plate 52 drives the convex ball rod 53 to move synchronously. Through heat conduction, the movement of the convex ball rod 53 expands the heat coverage area of ​​the heating plate 52 on the display component 41, preventing moisture corrosion inside the display component 41 and avoiding short circuits.

[0032] The short-circuit protection device 5 also includes a vertical rod 54, a corrugated guide plate 55, a hook-shaped spring plate 56, and a vibrating ball 57. The top of the vertical rod 54 is slidably installed inside the arc-shaped groove of the electric telescopic rotating column 51. The top of the corrugated guide plate 55 is fixedly installed at the bottom of the vertical rod 54, and the bottom of the corrugated guide plate 55 is slidably connected to the bottom of the inner wall of the display component 41. The back of the hook-shaped spring plate 56 is fixedly installed on the back of the inner wall of the display component 41. The top of the vibrating ball 57 is fixedly installed at the bottom of the hook-shaped spring plate 56, and the arc surface of the vibrating ball 57 is located on the corrugated guide plate 55. On the moving trajectory, when the electric telescopic rotating column 51 rotates, the vertical rod 54 is restricted by the arc groove, which enables the vertical rod 54 to move left and right. The vertical rod 54 drives the wave guide plate 55 to slide synchronously along the bottom of the inner wall of the display component 41. The wave guide plate 55 disturbs the cold air and moisture deposited at the bottom through the wave surface, causing the upper and lower airflows to alternate. When the wave guide plate 55 slides left and right, it abuts against the circular surface of the vibrating ball 57 on the right side of the hook-shaped spring plate 56 to generate vibration. The wave guide plate 55 enhances the disturbance effect on the moisture through vibration.

[0033] During use, when performing measurements, the main body 1 of the device is placed at the measurement location. The display component 41 and the detection component 42 are then activated. The operator holds the detection component 42 to measure the weld seam, and the data is displayed on the screen in the display component 41. The elastic design of the connecting wires allows the detection component 42 to stretch freely and fit more closely to the material being tested, resulting in more accurate test results. The locking block 43 ensures that the detection component 42 fits snugly inside, preventing damage from improper placement when stationary. At the start of the testing process, the shielding plate 44 is opened; when stationary, the shielding plate 44 protects the display screen. The screen is protected from damage. When the baffle 44 flips upward, it drives the retractable frame 45 to move downward. The retractable frame 45 drives the adhesion wheel 46 to slide synchronously along the outer wall of the screen. The adhesion wheel 46 starts to rotate due to frictional resistance, which improves the removal effect of the adhesion wheel 46 on the surface of the screen. This avoids manual wiping by staff, ensures display clarity, and reduces preparation time for testing. The adhesion wheel 46 drives the spring 47 to rotate and squeeze the screen to deform. After the squeezing force disappears, the spring 47 returns to its original position due to elasticity. When the spring 47 deforms, it expands the adhesion range of the adhesion wheel 46 on the original basis to improve the removal effect. When it returns to its original position, it bounces the attached dirt to ensure its own cleanliness.

[0034] When temperature sensor 2 and humidity sensor 3 detect that the external temperature is too low and the humidity is too high, the electric telescopic rotating column 51 is activated. The electric telescopic rotating column 51 rotates intermittently. The telescopic end of the electric telescopic rotating column 51 drives the heating plate 52 to move left and right and rotate. The heating plate 52 drives the convex ball rod 53 to move synchronously. Through heat conduction, the movement of the convex ball rod 53 expands the heat coverage area of ​​the heating plate 52 on the display component 41, avoiding moisture corrosion inside the display component 41 and preventing short circuits. When the electric telescopic rotating column 51 rotates, it relies on the arc groove to limit the vertical rod 54. The vertical rod 54 can move left and right, and the vertical rod 54 drives the wave guide plate 55 to slide synchronously along the bottom of the inner wall of the display component 41. The wave guide plate 55 disturbs the cold air and moisture deposited at the bottom through the wave surface, causing the airflow to alternate between the upper and lower parts and accelerating the removal efficiency of moisture. When the wave guide plate 55 slides left and right, it abuts against the circular surface of the vibrating ball 57 on the right side of the hook-shaped spring plate 56 and vibrates. The wave guide plate 55 enhances the disturbance effect on moisture through vibration, further avoiding short circuits caused by moisture erosion inside the display component 41, thereby reducing the accuracy of the detection results.

[0035] Please see Figures 1-8 Based on the above embodiments, another embodiment of the present invention further includes an anti-storage device 6 and an anti-error device 7. The anti-storage device 6 is disposed inside the anti-short circuit device 5, and the anti-error device 7 is disposed at the bottom of the device body 1.

[0036] The anti-storage device 6 includes a lead screw 61, an elliptical sheet 62, and an arc-shaped extrusion block 63. The back of the lead screw 61 is fixedly installed on the front of the telescopic end of the electric telescopic rotating column 51. The bottom of the elliptical sheet 62 is hinged to the outer wall surface of the lead screw 61. The bottom back of the arc-shaped extrusion block 63 is fixedly installed at the edge of the front of the lead screw 61, and the top arc surface of the arc-shaped extrusion block 63 contacts the arc surface of the elliptical sheet 62. The electric telescopic rotating column 51 drives the lead screw 61 to rotate, and the lead screw 61 drives the elliptical sheet 62 to rotate. Through the centrifugal force of rotation, the elliptical sheet 62 causes the airflow inside the convex ball rod 53 to be disturbed at a vertical angle. When the elliptical sheet 62 is vertical, it contacts the arc surface of the arc-shaped extrusion block 63 and undergoes abutment deformation. When the elliptical sheet 62 is deformed, it stirs the airflow in an irregular shape.

[0037] The anti-storage device 6 also includes a desiccant 64, a telescopic rod 65, an L-shaped rod 66, and a hemispherical plate 67. The desiccant 64 slides inside and is sleeved on the outer wall surface of the lead screw 61. The back of the telescopic rod 65 is fixedly installed on the front of the telescopic end of the electric telescopic rotating column 51, and a spring is built into the telescopic end of the telescopic rod 65. The right side of one end of the back of the L-shaped rod 66 is fixedly installed on the left side of the outer wall of the telescopic rod 65. The back of the hemispherical plate 67 is fixedly installed on one end of the front of the L-shaped rod 66, and the hemispherical plate 67 is located on the inner wall of the nozzle of the desiccant 64. When rod 61 rotates, the restriction of the desiccant 64 by the spiral groove causes the desiccant 64 to slide to the right along the outer wall of the screw 61. The desiccant 64 pulls the telescopic rod 65 to extend synchronously. When the telescopic rod 65 extends to its limit, it pulls the desiccant 64 to deform and generate spray force. The desiccant 64 sprays the desiccant into the display component 41. When the desiccant 64 deforms, it slides along the outer wall of the L-shaped rod 66. At this time, the hemispherical plate 67 at the nozzle is removed from the cover. When the desiccant 64 is reset, the hemispherical plate 67 is reset and covers the nozzle.

[0038] The error prevention device 7 includes a telescopic base 71, an electric push rod 72, and a damping plate 73. The telescopic base 71 is located at the bottom of the main body 1 of the device. The bottom of the electric push rod 72 is fixedly installed at the top edge of the telescopic base 71, and the top of the telescopic end of the electric push rod 72 is fixedly connected to the bottom of the main body 1 of the device. The back of the damping plate 73 is fixedly installed on the front of the outer wall of the electric push rod 72 and the telescopic end of the electric push rod 72. When the electric push rod 72 is activated, the telescopic base 71 provides support and stability for the electric push rod 72. The telescopic end of the electric push rod 72 pushes the main body 1 of the device to rise to complete the height adjustment. The damping plate 73 supports the telescopic end of the electric push rod 72. The resistance of the damping plate 73 causes the electric push rod 72 to retract slowly, preventing the main body 1 of the device from causing the display component 41 to fall rapidly and collide.

[0039] The error prevention device 7 also includes a pull rod 74, a protective plate 75, a transmission plate 76, and a U-shaped scraper 77. The top of the pull rod 74 is hinged to the left side of the outer wall of the telescopic end of the electric push rod 72. The bottom of the protective plate 75 is hinged to the top edge of the telescopic base 71, and the right side of the protective plate 75 is hinged to the bottom of the pull rod 74. The transmission plate 76 is hinged between the left inclined surface of the protective plate 75 and the top of the telescopic end of the telescopic base 71. The outer wall of the U-shaped scraper 77 penetrates and is hinged inside the transmission plate 76, and the bottom of the U-shaped scraper 77 contacts the top of the telescopic end of the telescopic base 71. When the telescopic end of the electric push rod 72 rises... The pull rod 74 is driven to shift towards the main body 1 of the device. The pull rod 74 drives the protective plate 75 to move synchronously. The protective plate 75 provides buffer protection for the overall deformation slope of the device. The protective plate 75 causes the transmission plate 76 to move away from the main body 1 of the device. The transmission plate 76 pushes the telescopic base 71 to extend synchronously, increasing the contact area between the telescopic base 71 and the ground. The transmission plate 76 drives the U-shaped scraper 77 to move synchronously. The U-shaped scraper 77 scrapes the connection of the telescopic base 71 to prevent external solid objects from getting stuck at the connection and reducing the smoothness of the telescopic base 71's extension and retraction.

[0040] In use, the electric telescopic rotating column 51 drives the lead screw 61 to rotate, which in turn drives the elliptical sheet 62 to rotate. The centrifugal force of the rotation causes the elliptical sheet 62 to agitate the airflow inside the convex ball rod 53 at a vertical angle, further enhancing the mixing effect of heat and moisture and keeping the display component 41 dry. When the elliptical sheet 62 is vertical, it contacts the arc surface of the arc-shaped extrusion block 63, causing deformation. This deformation irregularly agitates the airflow, increasing the contact area between the elliptical sheet 62 and the moisture, thus improving the evaporation efficiency of the moisture. As the lead screw 61 rotates, the spiral groove restricts the drying bladder 64, causing it to slide to the right along the outer wall of the lead screw 61. The drying bladder 64 pulls the telescopic rod 65 to extend synchronously. When the telescopic rod 65 extends to its limit, it pulls... When the desiccant 64 deforms, it generates spray force. When the electric telescopic rotating column 51 stops rotating, the telescopic rod 65 elastically pulls the desiccant 64 back to its original position via a spring. The desiccant 64 sprays desiccant into the display component 41 to neutralize moisture, preventing moisture from evaporating due to heat and preventing moisture buildup. This also prevents long-term moisture buildup from causing rust on the internal components of the display component 41 and extending the replacement cycle of the components. At the same time, the desiccant 64 rotates vertically against the elliptical sheet 62, preventing the elliptical sheet 62 from rotating at an angle that would reduce the agitation effect on the moisture. When the desiccant 64 deforms, it slides along the outer wall of the L-shaped rod 66. At this time, the hemispherical plate 67 at the nozzle disengages from blocking. When the desiccant 64 returns to its original position, the hemispherical plate 67 returns to its original position and blocks again, preventing external moisture from entering the desiccant 64 through the nozzle and causing it to clump.

[0041] When the detection height needs to be adjusted, the electric push rod 72 is activated. At this time, the telescopic base 71 provides support and stability for the electric push rod 72. The telescopic end of the electric push rod 72 pushes the main body 1 of the device to rise. The main body 1 of the device drives the display component 41 and the detection component 42 to rise synchronously to complete the height adjustment. If the electric push rod 72 malfunctions and falls, the damping plate 73 supports the telescopic end of the electric push rod 72. The resistance of the damping plate 73 causes the electric push rod 72 to retract slowly, preventing the main body 1 from causing the display component 41 to fall rapidly and collide, thus avoiding a decrease in the detection accuracy of the detection component 42 and increased maintenance costs. When the telescopic end of the electric push rod 72 rises, it drives the pull rod 74 to shift closer to the main body 1 of the device. The pull rod 74 drives the protective plate. The protective plate 75 moves synchronously, providing buffer protection for the overall deformation of the device by the inclined surface, preventing external impacts from directly contacting the entire device and causing damage to components while delaying the testing progress; the protective plate 75 causes the transmission plate 76 to move away from the main body 1 of the device, and the transmission plate 76 pushes the telescopic base 71 to extend synchronously, increasing the contact area between the telescopic base 71 and the ground, improving the stability of the device, and preventing the main body 1 from becoming unstable due to rising; the transmission plate 76 drives the U-shaped scraper 77 to move synchronously, and the U-shaped scraper 77 scrapes the connection of the telescopic base 71 to prevent external solid objects from getting stuck at the connection and reducing the smoothness of the telescopic base 71's extension and retraction. When the U-shaped scraper 77 resets, it covers the connection to ensure cleanliness.
