Description

Technical Field

[0001] This utility model belongs to the field of tunnel inspection technology, specifically relating to an intelligent inspection vehicle based on visual sensing function. Background Technology

[0002] my country has a complex topography, with mountains, plateaus, and hills accounting for approximately 67% of its land area, of which mountains and hills alone cover 43%. This diverse terrain poses a significant obstacle to the development of transportation. To overcome these difficulties, my country needs to construct highway infrastructure in these regions, an indispensable part of which is the excavation of tunnels traversing mountains. As the number of tunnels increases annually, tunnel construction and maintenance have become increasingly important and complex. Tunnel construction is a complex and risky engineering activity. During highway tunnel construction, there are risks of geological disasters, collapses, and floods. These accidents can cause tunnel collapses, personal injuries, equipment damage, and other safety incidents. To ensure the safety and smooth progress of highway tunnel construction, regular inspections of the tunnels under construction are necessary.

[0003] With the development of technology, intelligent inspection vehicles for tunnel inspection have been developed and applied. These vehicles can be remotely controlled via pre-set paths, computers, or handheld devices to enter tunnels for inspection, replacing manual labor. This avoids the risk of personnel being exposed to hazardous environments, reduces the workload of manual inspections, shortens inspection time, and improves efficiency. Simultaneously, it can monitor safety parameters within the tunnel in real time, promptly identifying potential safety hazards and improving construction safety.

[0004] However, the monitoring camera on the inspection vehicle is fixedly mounted on the monitoring rack, which is fixed to the vehicle body. Therefore, it is not convenient to adjust the monitoring camera from multiple angles for monitoring, and it is not convenient to fold the monitoring rack after use. To address this, we propose an intelligent inspection vehicle based on visual sensing function. Utility Model Content

[0005] The purpose of this utility model is to provide an intelligent inspection vehicle based on visual sensing function, so as to solve the problems mentioned in the background art, that the monitoring camera on the inspection vehicle is fixedly installed on the monitoring frame, and the monitoring frame is fixed on the vehicle body of the inspection vehicle, which makes it inconvenient to adjust and monitor the monitoring camera from multiple directions, and also makes it inconvenient to fold the monitoring frame after use.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent inspection vehicle based on visual sensing function, comprising an inspection vehicle body, two fixing blocks fixedly mounted on the surface of the inspection vehicle body, a monitoring frame rotatably mounted between the two fixing blocks, a support arm fixedly mounted on the inner wall of the monitoring frame, a retaining rod slidably mounted on the support arm, an operating panel fixedly mounted on the top of the retaining rod, a retaining groove fixedly mounted on the surface of the inspection vehicle body, the bottom end of the retaining rod engaging with the retaining groove, a motor one fixedly mounted on the inner wall of the monitoring frame, a turntable fixedly mounted on the output shaft end of the motor one, two side plates fixedly mounted on the surface of the turntable, a mounting base rotatably mounted between the two side plates, a motor two fixedly mounted on the side of one of the side plates, the output shaft of the motor two fixedly connected to the rotation shaft of the mounting base, and a monitoring camera detachably mounted on the side of the mounting base.

[0007] The above solution utilizes a fixed block to work with the monitoring frame, allowing the frame to rotate, unfold, and close. When unfolded, it is locked using a retaining rod; when closed, it is locked using a fixing rod, a fixing nut, and a fixing plate. This allows the monitoring frame to be opened during tunnel inspections and retracted afterward, providing convenient operation and avoiding the space-consuming issue of the frame being constantly unfolded when not in use. The solution also incorporates two motors: motor one for horizontal rotation adjustment and motor two for pitch adjustment, enabling multi-directional monitoring. Furthermore, the use of insert plates and clips facilitates easy installation and removal of the monitoring camera, simplifying maintenance.

[0008] In the above scheme, it should be noted that both motor one and motor two are electrically connected to an external power supply.

[0009] In a preferred embodiment, a limiting ring is fixedly installed on the outer surface of the retaining rod, the limiting ring is located inside the support arm, a limiting block is fixedly installed on the inner wall of the support arm, and the limiting ring has an opening for the limiting block to pass through.

[0010] By adopting the above scheme, the setting of the limiting ring can prevent the fixing rod from sliding out of the fixing groove, which achieves a good limiting effect. When the fixing rod leaves the fixing groove, the limiting ring will move to the upper side of the limiting block through the opening. At this time, rotating the fixing rod can make the opening on the limiting ring misalign with the limiting block, preventing the fixing rod from accidentally resetting and ensuring good stability in operation.

[0011] In a preferred embodiment, a spring is sleeved on the outside of the retaining rod. The spring is located inside the support arm, and its two ends are fixedly connected to the inner wall of the support arm and the surface of the limiting ring, respectively.

[0012] Using the above scheme, when the retaining rod is disengaged from the retaining groove, the spring is in a deformed state. Therefore, the elastic force of the spring can be used to drive the retaining rod to quickly reset and lock into the retaining groove.

[0013] In a preferred embodiment, a support ring is fixedly installed on the lower surface of the turntable, and an arc-shaped groove is provided on the surface of the monitoring frame for the support ring to slide.

[0014] By adopting the above scheme, and utilizing the support ring in conjunction with the arc-shaped groove, the stable rotation of the turntable can be ensured, and shaking can be avoided.

[0015] In a preferred embodiment, the mounting base has slots and grooves on its side and surface, respectively, and the slots and grooves are connected. A plug plate is fixedly installed on the side of the monitoring camera. A groove is formed on the surface of the plug plate, and a spring and a telescopic rod are fixedly installed on the inner wall of the groove. The spring and the telescopic rod are both fixedly connected to the plug plate. The plug plate and the slot are used together, and the plug plate and the groove are used together.

[0016] Using the above solution, the insert plate is inserted into the slot, and the elastic force of the second spring drives the card plate into the slot, thereby completing the convenient installation of the surveillance camera. The telescopic rod can support the card plate and prevent it from shaking.

[0017] In a preferred embodiment, a fixing rod is fixedly installed on the side of the inspection vehicle body. The surface of the fixing rod has threads and a fixing nut is installed in the threads. A fixing plate is fixedly installed on the side of the monitoring frame. The fixing plate has a slot for the fixing rod to pass through.

[0018] Using the above solution, the monitoring frame can be fixed after folding by passing the fixing rod through the bayonet and using the fixing nut, thus preventing it from loosening.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This intelligent inspection vehicle based on vision sensing function is used in conjunction with a monitoring frame by setting a fixed block. The monitoring frame can be rotated to unfold and close. After unfolding, it is locked by a fixing rod. After closing, it is locked by a fixing rod, a fixing nut and a fixing plate. Thus, the monitoring frame can be opened when inspecting inside the tunnel and retracted after the inspection is completed. The operation is convenient and avoids the problem of the monitoring frame occupying a lot of space when it is not in use.

[0021] This intelligent inspection vehicle based on vision sensing is equipped with two motors, Motor 1 and Motor 2, which work together to achieve horizontal rotation adjustment and pitch rotation adjustment, thus enabling multi-directional monitoring and adjustment. With the help of plug-in plates and card plates, the monitoring camera can be easily installed and removed, facilitating disassembly and maintenance. Attached Figure Description

[0031] Please see Figure 1-8This utility model provides an intelligent inspection vehicle based on visual sensing function, including an inspection vehicle body 1. Two fixing blocks 2 are fixedly installed on the surface of the inspection vehicle body 1. A monitoring frame 3 is rotatably installed between the two fixing blocks 2. A support arm 4 is fixedly installed on the inner wall of the monitoring frame 3. A retaining rod 5 is slidably installed on the support arm 4. An operation panel 6 is fixedly installed at the top of the retaining rod 5. A retaining groove is fixedly installed on the surface of the inspection vehicle body 1. The bottom end of the retaining rod 5 cooperates with the retaining groove. A motor 7 is fixedly installed on the inner wall of the monitoring frame 3. A turntable 8 is fixedly installed at the end of the output shaft of the motor 7. Two side plates 9 are fixedly installed on the surface of the turntable 8. A mounting base 11 is rotatably installed between the two side plates 9. A motor 10 is fixedly installed on the side of one of the side plates 9. The output shaft of the motor 10 is fixedly connected to the rotation shaft of the mounting base 11. A monitoring camera 12 is detachably installed on the side of the mounting base 11.

[0032] By using the fixing block 2 in conjunction with the monitoring frame 3, the monitoring frame 3 can be rotated to unfold and close. After unfolding, it is locked by the fixing rod 5, and after closing, it is locked by the fixing rod 22, the fixing nut 21 and the fixing plate 23. Thus, the monitoring frame 3 can be opened when inspecting inside the tunnel, and the monitoring frame 3 can be retracted after the inspection is completed. The operation is convenient and avoids the problem of the monitoring frame 3 occupying a lot of space when it is not in use because it is always in the unfolded state. By setting motor 1 7 and motor 2 10 together, the horizontal rotation adjustment is achieved by motor 1 7 and the pitch rotation adjustment is achieved by motor 2 10, thus realizing multi-directional monitoring adjustment. With the help of the plug plate 17 and the card plate 19, the monitoring camera 12 can be easily disassembled and installed, which is convenient for disassembly, assembly and maintenance.

[0033] A limiting ring 13 is fixedly installed on the outer surface of the retaining rod 5. The limiting ring 13 is located inside the support arm 4. A limiting block 14 is fixedly installed on the inner wall of the support arm 4. An opening is provided on the limiting ring 13 for the limiting block 14 to pass through. The setting of the limiting ring 13 can prevent the retaining rod 5 from sliding out of the retaining groove, thus achieving a good limiting effect. When the retaining rod 5 is separated from the retaining groove, the limiting ring 13 will move to the upper side of the limiting block 14 through the opening. At this time, rotating the retaining rod 5 can make the opening on the limiting ring 13 misalign with the limiting block 14, preventing the retaining rod 5 from accidentally resetting and ensuring good stability during operation.

[0034] A spring 15 is sleeved on the outside of the retaining rod 5. The spring 15 is located inside the support arm 4. The two ends of the spring 15 are fixedly connected to the inner wall of the support arm 4 and the surface of the limiting ring 13, respectively. When the retaining rod 5 is disengaged from the retaining groove, the spring 15 is in a deformed state. Therefore, the elastic force of the spring 15 can be used to drive the retaining rod 5 to quickly reset and be stuck into the retaining groove.

[0035] A support ring 16 is fixedly installed on the lower surface of the turntable 8. An arc-shaped groove is provided on the surface of the monitoring frame 3 for the support ring 16 to slide. By using the support ring 16 in conjunction with the arc-shaped groove, the turntable 8 can be rotated stably and the shaking phenomenon can be avoided.

[0036] The mounting base 11 has slots and slots on its side and surface, respectively, and the slots and slots are connected. A plug plate 17 is fixedly installed on the side of the surveillance camera 12. The surface of the plug plate 17 has a groove, and a spring 18 and a telescopic rod 20 are fixedly installed on the inner wall of the groove. Both the spring 18 and the telescopic rod 20 are fixedly connected to the slot plate 19. The plug plate 17 and the slot work together, and the slot plate 19 and the slot work together. The plug plate 17 is inserted into the slot, and the spring force of the spring 18 drives the slot plate 19 to snap into the slot, thereby completing the convenient installation of the surveillance camera 12. The telescopic rod 20 can support the slot plate 19 to prevent shaking.

[0037] A fixing rod 22 is fixedly installed on the side of the inspection vehicle body 1. The surface of the fixing rod 22 has threads and a fixing nut 21 is installed in the threads. A fixing plate 23 is fixedly installed on the side of the monitoring frame 3. The fixing plate 23 has a slot for the fixing rod 22 to pass through. By using the fixing rod 22 to pass through the slot and cooperate with the fixing nut 21, the folded monitoring frame 3 can be fixed to prevent it from loosening.

[0038] In use, the inspection vehicle 1 is started, allowing the entire device to move inside the tunnel. The monitoring camera 12 provides real-time monitoring within the tunnel. Motor 7 drives the turntable 8 to rotate, which in turn drives the monitoring camera 12 to perform horizontal rotation monitoring. Motor 10 drives the mounting base 11 to rotate, which in turn drives the monitoring camera 12 to perform pitch rotation monitoring, thus achieving multi-directional monitoring. After the inspection is completed, pulling the control panel causes the retaining rod 5 to move and disengage from the retaining groove. Simultaneously, the limiting ring 13 moves synchronously with the retaining rod 5 and compresses the spring 15, causing it to deform. When the retaining rod 5 disengages... When the retaining ring 13 moves to the upper side of the retaining block 14 through the opening, the retaining rod 5 is rotated to make the opening on the retaining ring 13 misalign with the retaining block 14, so as to prevent the retaining rod 5 from resetting. At this time, the monitoring frame 3 is unlocked and can be rotated and folded up. At this time, the fixing rod 22 will enter the slot on the fixing plate 23. Then, the fixing nut 21 is tightened to lock the monitoring frame 3 after folding. When it is necessary to remove the monitoring camera 12, press the card plate 19 to make the card plate 19 disengage from the slot, thereby unlocking the monitoring camera 12, so that the monitoring camera 12 can be removed.
