Description

Technical Field

[0001] This utility model relates to the field of cable detection technology in underground conduits, and more particularly to a cable trench track detection system and a cable trench. Background Technology

[0002] The tunnels in power and communication cable trenches have harsh environments, hot and humid in summer and cold and damp in winter. They often contain water and harmful gases, posing safety hazards and greatly hindering manual inspections. Furthermore, inspectors cannot enter when the cables are energized, which makes early handling of cable accidents difficult. Generally, accidents are only discovered when short circuits or even fires occur, ultimately causing significant impacts on production.

[0003] Meanwhile, due to the low frequency and long intervals of manual inspections, relevant units cannot accurately and timely understand the possible situations during the inspection intervals, nor can they collect, analyze, and organize historical data of power cable lines in real time, making it difficult to obtain accurate equipment operating status.

[0004] If robots are used for inspection, the presence of cables and complex ground conditions, coupled with the potential for obstacles like steps, make it difficult for the robots to traverse them. Therefore, current technologies often employ tracks suspended from the top of the cable tunnel to guide the robot's movement, as seen in CN102562154A. However, due to water leakage in cable tunnels, the track surface becomes damp. Over time, this can lead to rust or dust adhering to the track surface, increasing resistance for the cable tunnel inspection robot. This not only increases the pressure on the drive mechanism but can also prevent normal inspection. Utility Model Content

[0026] This utility model provides a cable trench track detection system.

[0027] like Figures 1-2 As shown, the cable trench track inspection system provided in this embodiment of the present invention includes a flexible track 10 and an inspection robot 20 slidably disposed within the flexible track 10. The flexible track 10 includes a sliding groove 11 extending along its length direction. The sliding groove 11 includes a first groove portion 111 and a second groove portion 112. The first groove portion 111 opens upward to form a receiving space 12. The inspection robot 20 is disposed in the receiving space 12 and can walk along the first groove portion 111. The second groove portion 112 is disposed below the first groove portion 111 and communicates with the first groove portion 111. The cable 23 of the inspection robot 20 can be disposed within the second groove portion 112.

[0028] In this embodiment, the flexibility of the track can be used to transform obstacles such as steps in the cable trench into gently undulating uphill or downhill slopes, greatly improving the robot's mobility. Furthermore, the flexible track 10 can be laid on the cables in the cable trench to reduce the slope when going uphill or downhill, thus reducing the difficulty for the robot body 21 to operate within it.

[0029] In addition, the upward opening of the recessed portion also allows the base 211 to extend the detection element 212, such as a camera, out of the track to obtain detection information such as image information.

[0030] In an alternative embodiment, the cross-section of the flexible track 10 for the cable trench can be C-shaped overall.

[0031] Once the flexible track 10 for cable trenches is placed into the cable trench, even if the angle of the upward opening varies slightly at different positions along the length of the flexible track 10, it will not prevent the robot body 21 from continuing to move forward at the lowest position of the opening. This allows the robot body 21 to operate normally and perform its functions. In particular, when the robot body 21 uses a camera to photograph the situation inside the cable trench, it can maintain a stable shooting angle, which helps observers to more accurately judge the situation inside the cable trench and improves the efficiency of monitoring and maintenance.

[0032] In an optional embodiment, the flexible track 10 is made of silicone. Using silicone as the flexible track 10 for cable trenches not only provides moderate deformation capacity but also a certain degree of rigidity. After being laid on steps or trenches in the cable trench, it maintains a certain curvature to facilitate the smooth passage of the robot body 21 through that section of the flexible track 10, improving the robot body 21's passability. Furthermore, silicone also has a certain degree of insulation, ensuring that the robot body 21 is not affected by the cables while running within the track, thus protecting the safety of the cable trench inspection robot itself.

[0033] The inspection robot 20 includes a robot body 21, a connecting part 22, and a cable 23. The connecting part 22 connects the robot body 21 and the cable 23. The robot body 21 is located within the first groove 111, and the cable 23 is located within the second groove 112. The sliding groove 11 includes a through hole connecting the first groove 111 and the second groove 112, and the connecting part 22 is located within the through hole. The cable 23 can be connected to a control device to transmit the detection information obtained by the robot body 21 to the control device. Specifically, the cable 23 reel can be used to place the robot body 21 into a track. The control device controls the robot body 21 to move within the track. During movement, a camera captures video and images of the cable trench, and the information is transmitted back to the control device via the cable 23.

[0034] In use, the aforementioned track and cable trench inspection robot can be considered as a whole. First, the flexible track 10 is inserted from one shaft into the cable trench until one end of the flexible track 10 emerges from the next shaft. The length of the flexible track 10 should not be less than the distance between two adjacent shafts. Then, the robot body 21 is placed into the recessed section, allowing it to move within the recess. The robot body 21 is controlled by a control device to move within the track. During movement, a camera captures video and images of the cable trench, and the information is transmitted back to the control device via cable 23.

[0035] Additionally, please refer to Figure 1 and Figure 2 The first groove portion 111 includes concave portions 13 located on both sides, and the inspection robot 20 is provided with sliding rollers 24 on both sides, and the sliding rollers 24 are slidably disposed in the concave portions 13.

[0036] Meanwhile, the cable trench track detection system also includes a guide section 30, which is located within the first groove 111 and connected by a shock-absorbing plate 31. Sliding rollers 24 are provided on both sides of the guide section 30, and the sliding rollers 24 are located within the recessed portion 13. In this embodiment, the cooperation between the sliding rollers 24 and the recessed portion 13 not only improves the movement efficiency of the robot body 21 within the flexible track 10, but also allows the sliding rollers 24 to be held in place by the recessed portion 13, preventing the inspection robot 20 from detaching from the flexible track 10.

[0037] The inspection robot 20 also includes a support plate 25, which has a receiving cavity 251. The detection element 212 is disposed within the receiving cavity 251. One end of the support plate 25 is rotatably mounted on the base 211, and the other end of the support plate 25 is connected to the shock-absorbing plate 31. The support plate 25 can swing within a certain angle, driving the detection element 212 to rotate within a certain angle according to the forward walking trajectory of the guide 30, thus preventing hard interference.

[0038] Furthermore, this utility model also provides a cable trench, which includes a trench body and a cable trench track detection system disposed within the trench body. Since this cable trench adopts all the technical solutions of the above embodiments, it possesses at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be elaborated upon here.

[0039] The above description is merely a preferred embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the concept of this utility model and the contents of this specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this utility model. For example:

[0040] The robot body 21 is self-powered and can move forward on its own within the trolley. In fact, the trolley can also be propelled forward by a push rod. When the flexible track 10 for the cable trench is not perfectly straight, the push rod can deform accordingly as it moves forward to adapt to the shape of the flexible track 10.

[0041] The robot body 21 is electrically connected to the control device via cable 23. In fact, the robot body 21 and the control device can also transmit information wirelessly. Wireless communication is a mature technology and will not be elaborated upon further in this application.

[0042] The detection element can be a camera, but other detection elements can also be used, such as infrared cameras, ultrasonic detectors, radar, etc.
