Description

Technical Field

[0001] This utility model relates to the field of lighting technology, specifically to a lighting structure for unmanned vehicles suitable for long tunnels. Background Technology

[0002] Long tunnel projects such as traffic tunnels, water conservancy water conveyance tunnels, pipe gallery projects and coal mine roadways undertake important functions such as transportation, water resource allocation, waterproofing and irrigation, energy and signal transmission, depending on their different uses. Therefore, it is of great significance to detect the tunnel service environment and defects such as cracks and holes in the tunnel wall concrete.

[0003] Currently, in long tunnel inspections, unmanned vehicles (UAVs) undertake key tasks such as inspection, material transportation, and environmental monitoring. The stability, adaptability, and ease of installation of their supporting lighting structures directly determine the safety and efficiency of the operation. However, traditional UAV lighting structures have many technical shortcomings, making it difficult to meet the complex environment and efficient operation and maintenance requirements of long tunnels. Specific problems are as follows:

[0004] The lighting equipment is not fixed and unstable, and the vibration of driving can easily lead to functional failure. The surface of long tunnels often contains gravel, potholes and undulating slopes. Traditional unmanned vehicle lighting structures mostly use a single bolt or simple buckle structure, which can easily cause the unmanned vehicle to vibrate violently when driving in the tunnel, causing the bolt to loosen and the buckle to fall off, increasing the collision risk of the unmanned vehicle.

[0005] Traditional fixed structures have poor adaptability and can only accommodate lighting equipment of a single size and illumination coverage angle. When replacing lamps of different power and specifications or adjusting the illumination coverage angle, it is necessary to re-drill holes and adjust the bolt positions, resulting in low installation efficiency and difficulty in adapting to the different lighting intensities and illumination coverage angles required in long tunnel operations. Therefore, an unmanned vehicle lighting structure suitable for long tunnels is proposed. Utility Model Content

However, the following embodiments are merely preferred embodiments of the present invention and are not exhaustive.

[0025] Example:

[0026] like Figures 1-3As shown, this utility model provides a lighting structure for unmanned vehicles suitable for long tunnels, including a mounting plate 1, a lighting equipment fixing component 2 is provided inside the mounting plate 1, a lighting equipment 3 is fixed inside the lighting equipment fixing component 2, auxiliary lighting equipment fixing components 4 are provided on both sides of the lighting equipment fixing component 2 inside the mounting plate 1, and an adjustable connecting bracket component 5 is provided on the back of the mounting plate 1.

[0027] The lighting equipment fixing assembly 2 includes a first slide 21, a bidirectional lead screw 22, a lead screw slider 23, a limiting plate 24, and a motor 25;

[0028] The first slide groove 21 is located in the middle of the mounting plate 1. The bidirectional lead screw 22 is located inside the first slide groove 21. Two sets of lead screw sliders 23 are threaded to both ends of the bidirectional lead screw 22, and both sets of lead screw sliders 23 are located inside the first slide groove 21. The limiting plate 24 is fixed to the top surface of the lead screw sliders 23. The motor 25 is located in the middle of the side of the mounting plate 1. The output end of the motor 25 is connected to one end of the bidirectional lead screw 22. During operation, the motor 25 drives the bidirectional lead screw 22 to rotate. During the rotation of the bidirectional lead screw 22, it drives the two sets of lead screw sliders 23 to move in opposite directions. The limiting plate 24 moves in opposite directions synchronously under the drive of the lead screw sliders 23. During the movement, the limiting plate 24 clamps the lighting equipment 3. The opposite clamping method can better adapt to different specifications of lighting equipment 3 and has high fixing efficiency.

[0029] The lighting equipment fixing component 2 also includes a locking block 26, which is disposed on the surface of the limiting plate 24. The side of the lighting equipment 3 is provided with a slot that cooperates with the locking block 26. When the limiting plate 24 moves, the locking block 26 on the surface of the limiting plate 24 is driven by the limiting plate 24 and embedded into the slot on the side of the lighting equipment 3, thereby further fixing the lighting equipment 3 by nesting connection.

[0030] The lighting equipment auxiliary fixing assembly 4 includes a second slide 41, a spring guide rod 42, a spring 43, a guide rod slider 44, and a fixing plate 45;

[0031] Two sets of second slide grooves 41 are respectively opened inside the mounting plate 1 at positions on both sides of the first slide groove 21. Spring guide rods 42 are disposed inside the second slide grooves 41. Springs 43 and guide rod sliders 44 are both sleeved on the outside of the spring guide rods 42. One end of the spring 43 is connected to the inner wall of the second slide groove 41, and the other end of the spring 43 is connected to the outer wall of the guide rod slider 44. Fixing plates 45 are fixed to the top of the guide rod slider 44. During the initial fixing of the lighting equipment 3, the two sets of fixing plates 45 are pushed to move and unfold in opposite directions. 5. During the movement, the guide rod slider 44 moves synchronously along the spring guide rod 42. The spring 43 is stretched and deformed during the movement of the guide rod slider 44. When the lighting equipment 3 is placed on the surface of the mounting plate 1, the two sets of fixing plates 45 are released synchronously. The spring 43 returns to its original deformation. Under the elastic force of the spring 43, the guide rod slider 44 drives the fixing plate 45 to move in opposite directions to clamp the lighting equipment 3.

A bracket 53 is sleeved on the outside of the connecting shaft 52. A bracket fixing rod 54 is set between the two sets of brackets 53. An angle adjustment limiting component 55 is set between the bracket 53 and the ear plate 51. The movement of the bracket 53 relative to the ear plate 51 is limited by the angle adjustment limiting component 55. After the setting position of the bracket 53 is fixed, pushing the mounting plate 1 will cause the mounting plate 1 to drive the ear plate 51 to rotate relative to the connecting shaft 52. After the angle between the ear plate 51 and the bracket 53 meets the requirements, the setting angle between the ear plate 51 and the bracket 53 can be locked by the angle adjustment limiting component 55.

[0034] The angle adjustment limiting component 55 includes a limiting hole group 551 and a pin 552. The limiting hole group 551 is disposed on the surface of the ear plate 51, and the pin 552 is disposed inside the bracket 53 at a position corresponding to the pin 552. The limiting hole group 551 consists of several sets of round holes, which are arranged in a fan-shaped manner inside the ear plate 51. When locking, the pin 552 is pushed to insert into the corresponding round hole of the limiting hole group 551. At this time, the relative position of the ear plate 51 and the bracket 53 is locked. By adjusting the angle, it can illuminate long tunnels and also meet the needs of side wall inspection, making it highly versatile.

[0035] Several sets of screw holes are provided at the middle position of the bracket fixing rod 54. Each set of screw holes is threaded with a bolt 6. When fixing the bracket 53, the bracket fixing rod 54 is aligned with the connection point of the unmanned vehicle.
