Description

Technical Field

[0001] This invention belongs to the field of tunnel segment inspection technology, specifically an intelligent tunnel segment inspection device. Background Technology

[0002] Intelligent tunnel segment inspection refers to the process of automatically detecting and analyzing the quality, dimensions, and appearance of tunnel segments using advanced technologies such as artificial intelligence, machine vision, and 3D scanning. Tunnel segments are precast ring-shaped components used in underground engineering (especially shield tunneling) to support the surrounding rock of tunnels, isolate groundwater, and maintain the stability of the tunnel structure. They are the core component of tunnel lining, and their quality directly determines the safety, durability, and waterproofing of the tunnel. They are the "lifeline components" of underground engineering projects such as subways, river-crossing tunnels, and integrated utility tunnels. Intelligent inspection systems deployed on tunnel segments (such as prestressed concrete tunnel segments, tunnel lining segments, and steel structure segments) combine sensing, imaging, non-destructive testing (NDT), data analysis, and diagnostic models to automatically detect and assess the geometry, material condition, surface defects, and internal structure.

[0003] However, existing technologies often have the following drawbacks: intelligent segment inspection devices may have blind spots during inspection, resulting in undetected areas and affecting the inspection results. If defects in key parts such as ends, joints, and areas with uneven stress are missed for a long time, they may gradually deteriorate during subsequent operation, leading to sudden failures or distorted material deterioration trends. Diagnosis and remaining life estimation based on incomplete data may lead to deviations in maintenance plans, increasing costs or safety risks.

[0004] Therefore, the present invention provides an intelligent detection device for tunnel segments. Summary of the Invention

[0028] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0029] Reference Figure 1 - Figure 7 This invention provides two technical solutions:

[0030] Example 1:

[0031] A segment intelligent detection device includes a tube 1, an embedding groove 2 is formed on the outer surface of the tube 1, a detection mechanism is fixedly connected to the side wall of the embedding groove 2, a connecting cover 3 is fixedly connected to both ends of the outer surface of the tube 1, a prediction alarm mechanism is fixedly connected to both sides of the connecting cover 3, and a dynamic detection mechanism is fixedly connected to the surface of the tube 1.

[0032] The dynamic detection mechanism includes a support 4, one end of which is fixedly connected to the surface of the tube 1. A support rod 5 is fixedly connected to the inner wall of the support 4. A copper coil 6 is embedded on the outer surface of the support rod 5. A sleeve 7 is sleeved on the outer surface of the copper coil 6. A connecting rod 8 is fixedly connected to one end of the sleeve 7. A detector 9 is fixedly installed in the middle of the upper surface of the connecting rod 8. A magnetic sheet 10 is fixedly connected to one side of the sleeve 7, and a magnetic sheet 11 is fixedly connected to the other side of the sleeve 7. The addition of a dynamic detection mechanism to the outside of the tube 1 can cover areas that are difficult to cover during internal tube detection. By deploying the dynamic mechanism on the outside, multi-point synchronous sampling of the tube surface, shell and connection parts can be achieved, improving the integrity of the detection. In the operating environment, factors such as temperature, vibration and displacement will introduce systematic errors. The dynamic detection mechanism can compensate for these errors in real time, improving diagnostic accuracy. The kinematic adjustment capability of the external mechanism allows the detector 9 to adaptively align according to the geometry of the tube, reducing blind spots and false detections.

[0033] Example 2:

[0034] The detection mechanism includes a slide rod 12, one end of which is fixedly connected to the side wall of the embedded groove 2. An A connecting ring 13 is fixedly connected to the middle of the outer surface of the slide rod 12. Connecting sleeves 14 are fixedly connected to both sides of the A connecting ring 13. A push rod 15 is inserted into the inside of the connecting sleeve 14. A B connecting ring 16 is fixedly connected to one end of the push rod 15. Grooves are formed on the upper surfaces of both the A connecting ring 13 and the B connecting ring 16. A wireless sensor 17 is fixedly installed inside the grooves. An A magnetic block 18 is inserted into the inner bottom wall of the connecting sleeve 14. The surface of the A magnetic block 18 is fixed... A spring 19 is fixedly connected to one end of the spring 19, and a magnetic block 20 B is fixedly connected to one end of the spring 19. The surface of the magnetic block 20 B is fixedly connected to the other end of the push rod 15. During detection, the push rod 15 in the detection mechanism pushes the connecting ring 16 B to both sides, which can realize multi-point detection outside the tube 1, increase the detection coverage, improve the ability to detect multiple points simultaneously, and reduce the occupation and interference of the internal space of the tube 1. External detection causes less disturbance to the internal space of the tube 1, reduces interference and coupling error to the internal sensor, and reduces the error that occurs during detection.

[0035] The predictive alarm mechanism includes a slide rail 21, with its side fixedly connected to one side of the connecting cover 3. A copper coil 22 (B) is embedded in the inner wall of the slide rail 21. A sliding block 23 is snapped onto the outer surface of the slide rail 21. An alarm 24 is fixedly connected to the surface of the sliding block 23. A magnetic sheet 25 (C) is fixedly connected to one side of the sliding block 23, and a magnetic sheet 26 (D) is fixedly connected to the other side of the sliding block 23. Both ends of the slide rail 21 are fixedly connected to a stop block 27. A wire 28 is fixedly connected to the upper surface of one of the stop blocks 27, and a controller 29 is fixedly connected to one end of the wire 28. In the intelligent detection of pipe segments, a subsystem or module that issues an early warning based on real-time monitoring data, historical trends, and model predictions achieves a management method of early warning followed by processing through early identification of abnormal trends, dynamic adjustment of thresholds, and assessment of remaining lifespan and correctiveness. During detection, the predictive alarm mechanism intervenes early in key areas, reducing the probability and scale of accidents. In addition, when a fault is detected, it can react quickly and issue an alarm, facilitating personnel to take corresponding measures as soon as possible.

[0036] The inner wall of the tube 1 is provided with a processing groove, and the tube segment mold is installed inside the processing groove.

[0037] Working principle: When inspecting the segments inside the tube 1, a detection mechanism is installed in the embedded groove 2 on the outside of the tube 1. This mechanism performs preliminary inspection of the segments. Magnetic block A 18 and magnetic block B 20 are activated. Magnetic block A 18 pushes magnetic block B 20 via spring 19. Magnetic block B 20 pushes push rod 15, which moves within connecting sleeve 14. Push rod 15 pushes connecting ring B 16 forward. As connecting ring B 16 moves, it moves wireless sensor 17, enabling multi-point detection inside the tube 1. This increases the detection coverage, enhances simultaneous multi-point detection capability, and reduces the occupancy and interference with the internal space of the tube 1. External detection causes less disturbance to the internal space of the tube 1, reducing... To reduce interference and coupling errors of internal sensors and minimize errors during detection, a predictive alarm mechanism can be used to provide early prediction and real-time monitoring alarms for the exterior of the tube 1 during detection. Inside the slide rail 21, the B copper coil 22 drives the C magnetic plate 25 and D magnetic plate 26 to generate magnetic induction. The magnetic forces of the C magnetic plate 25 and D magnetic plate 26 repel each other. A circuit is formed using the B copper coil 22. When the positive terminal of the C magnetic plate 25 enters the B copper coil 22 and then returns to the negative terminal, the generated electromagnetic field drives the sliding block 23 to move continuously. Controlled by the stops 27 at both ends of the slide rail 21, the wires 28, and the controller 29, the alarm 24 will promptly sound when a fault is predicted. The alarm system is used to remind personnel to take maintenance measures. In the intelligent inspection of tunnel segments, it is a subsystem or module that issues early warnings based on real-time monitoring data, historical trends, and model predictions. Through early identification of abnormal trends, dynamic adjustment of thresholds, and assessment of remaining lifespan and corrective actions, it achieves a management approach of early warning followed by action. The predictive alarm mechanism intervenes early in key areas during inspection, reducing the probability and scale of accidents. Subsequently, to improve the inspection quality, a dynamic inspection mechanism is added to the outside of the tunnel segment 1. The principle of the dynamic inspection mechanism is the same as that of the predictive alarm mechanism. A short circuit is formed through copper coil 6 (A), and a sleeve 7 is sleeved on the outside. The two ends of the sleeve 7 have magnetic plates A 10 and B 1. 1. When the positive pole of magnetic sheet 10 enters copper coil 6 and then returns to the negative pole, the generated electromagnetic field can drive sleeve 7 to move continuously, causing sleeve 7 to drive connecting rod 8 and detector 9 to move outside tube 1, achieving dynamic detection effect. It can cover areas that are difficult to cover inside the tube segment. Through the dynamic mechanism deployed on the outside, multi-point synchronous sampling of the tube segment surface, shell and connection parts is achieved, improving the integrity of the detection. In the operating environment, factors such as temperature, vibration and displacement will introduce systematic errors. The dynamic detection mechanism can compensate in real time to improve diagnostic accuracy. The kinematic adjustment capability of the external mechanism allows detector 9 to adaptively align according to the geometry of the tube segment, reducing blind spots and false detections.
