[0002] According to the "Hydraulic Tunnel Safety Assessment Procedure (SLT 790-2020)," hydraulic tunnel management units must regularly conduct safety assessments every five years, with on-site safety inspections being a key component. This on-site safety assessment requires the use of the hydraulic tunnel's outage maintenance period as a time window. Therefore, hydraulic tunnel inspections place high demands on both efficiency and quality.

[0003] Currently, the lack of integrated inspection equipment for hydraulic tunnels has led to extremely low on-site inspection efficiency. Tunnel concrete appearance quality is mostly assessed manually, requiring personnel to walk and take photos. This method is not only time-consuming and labor-intensive, but also susceptible to human factors, significantly compromising the accuracy and consistency of inspection results. This is especially true in long tunnels or complex environments, where manual inspections are difficult to ensure efficiency and can lead to potential problems being missed.

[0004] Internal defect inspections for tunnels mostly rely on scaffolding with small wheels, mounted with radar and other equipment for manual inspection. Separate external inspection equipment and internal defect detection equipment are also available, but comprehensive inspection equipment specifically for hydraulic tunnels is lacking. This method is not only complex to operate but also requires significant manpower and time. Furthermore, the use of scaffolding for inspections carries certain safety risks, especially in the confined and complex environments of tunnels, which increases the safety risks for operators.

[0005] In summary, existing tunnel inspections lack integrated inspection equipment for hydraulic tunnels, which not only affects the efficiency and accuracy of inspections, but also increases the risk during the inspection process. In order to solve the above-mentioned problems, an integrated inspection device for hydraulic tunnels is now provided. Utility Model Content

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example 1

[0024] See also Figure 1-2 This embodiment provides an integrated detection device for hydraulic tunnels, including a scissor lift 1. The scissor lift 1 is based on the scissor lift machines of models XG0508HA, XG0608HA, and XG0608DC produced by Xugong Group Engineering Machinery Co., Ltd. The maximum operating height of the scissor lift 1 is about 5.5 to 6.6 meters, the width of the entire machine is about 0.81 meters, the maximum load capacity is about 200 to 240 kg, the weight of the entire machine is about 830 to 900 kg, and the travel speed is about 0.5 to 4 km / h. Both wheeled and crawler types can be used. The scissor lift 1 enables the equipment to move within a hydraulic tunnel with a diameter of 4.5 to 9.0 meters, with the maximum horizontal distance of the tunnel being the diameter. By manipulating the scissor lift 1 and adjusting the lifting and lowering of the scissor lift 1, the height of the scissor lift 1 can be adjusted, so that the scissor lift 1 can adapt to tunnels of different heights.

[0025] Motor equipment within 15cm of the scissor lift's bottom requires waterproofing measures, either by raising the internal motor position or by directly waterproofing it. During tunnel inspections, the tunnel must be drained, and the floor must not contain water higher than 15cm.

[0026] like Figure 1As shown, two scissor lifts 1 are provided, with an upper platform and a lower platform installed between the two scissor lifts 1. The upper platform and the lower platform are aligned vertically. Telescopic rods 11 are installed on both sides below the upper and lower platforms. One end of the output rod of the telescopic rod 11 is fixedly connected to the side wall of the scissor lift 1. The telescopic rod 11 adopts hydraulic expansion and contraction. By expanding and contracting the output rod of the telescopic rod 11, the distance between the two scissor lifts 1 can be adjusted.

[0027] like Figure 1 As shown, a control seat 12 is mounted on the upper end of the scissor lift 1. The control seat 12 includes a driver's seat and control equipment. The movement of the scissor lift 1 and the operation of the equipment can be controlled through the control seat 12. A guardrail 121 is also mounted on the upper end of the scissor lift 1. The guardrail 121 surrounds the left and right sides and rear side of the control seat 12 to protect the operator.

[0028] One end of the upper platform is fixedly connected to an arm 24, which is a telescopic bracket with a length of 1.0m to 1.5m. The end of the arm 24 away from the upper platform is provided with an image acquisition mechanism 2, which is used to detect the appearance of the inner wall of the tunnel. The image acquisition mechanism 2 includes a collection body 21, a collection camera 22 and a spotlight 23. Figure 2 As shown, the collecting body 21 is fixedly connected to the end of the support arm 24 away from the upper platform. Figure 1 As shown, there are eight acquisition cameras 22, and the eight acquisition cameras 22 are evenly arranged in a circular array on the outer wall of the acquisition body 21. The acquisition cameras 22 are set as CCD line cameras, and the acquired images cover the top of the tunnel, the arch spans or top plates on both sides and the upper part of the side walls, the left and right side walls, the bottoms of the left and right side walls, and the bottom plate. The inner wall and outer tube of the tunnel are fully captured. There are sixteen spotlights 23, and the spotlights 23 are also fixedly installed on the outer wall of the acquisition body 21. Each acquisition camera 22 is provided with a spotlight 23 on both sides. The spotlights 23 use LED lights with a white light source. The interior of the tunnel is illuminated by the spotlights 23 to ensure the image acquisition operation of the acquisition camera 22.

[0029] like Figure 1 As shown, a defect collection mechanism 3 is provided on the upper end of the upper platform and the two scissors-fork machines 1. The defect collection mechanism 3 includes a control body 31, a robotic arm 32 and a ground penetrating radar 33. The control body 31 is set to three, and the three control bodies 31 are respectively fixedly installed on the upper end of the upper platform and the two scissors-fork machines 1. Among them, the control body 31 on the upper end of the upper platform is rotatably installed with a robotic arm 32, and the side wall of the control body 31 at the upper end of the scissors-fork machine 1 is rotatably installed with two robotic arms 32, and the ground penetrating radar 33 is fixedly connected to the end of the robotic arm 32 away from the control body 31.

[0030] The ground-penetrating radar 33 can be moved by the robotic arm 32. The robotic arm 32 can be axially extended to a maximum range of 2.5m, can rotate in the front-back and left-right directions, and can be physically limited and fixed. During radar detection, the robotic arm 32 needs to be tilted at an angle of 20 to 25 degrees in the forward direction. There are five ground-penetrating radars 33 in total, and concrete radar images of five corresponding survey lines are collected. For tunnels with arched tops, one survey line is set for the arch top, two survey lines for the spandrels, and two survey lines for the side walls. The arch top is located at the center of the tunnel top, the spandrel is located at the intersection of the top and the side walls, and the side walls are located at the midpoint of the vertical side walls. For flat-top tunnels, one survey line is set at the center of the tunnel top, two survey lines are set on the left and right of the upper third of the side walls, and two survey lines are set on the left and right of the lower third of the side walls.

[0031] like Figure 1 As shown, a control body 111 is fixedly installed on the upper end of the lower platform, and a host, mobile power supply or other equipment for controlling the image acquisition mechanism 2 and the defect acquisition mechanism 3 is installed in the control body 111; holes need to be reserved on the upper platform to facilitate the wiring of electrical equipment.
