Technical Field

[0001] This application relates to the field of road safety protection technology, and in particular to an integrated anti-collision device for photovoltaic guardrails at tunnel exits. Background Technology

[0002] With the rapid development of my country's transportation industry, the number of tunnels being built is increasing daily. Tunnel exits are areas of abrupt change in the road environment, where vehicle driving conditions and the driver's visual environment change significantly, making these areas high-risk areas for traffic accidents. Currently, existing tunnel exit anti-collision devices are mostly simple structures with only basic anti-collision functions, failing to meet the safety protection needs of the complex environment at tunnel exits.

[0003] Meanwhile, against the backdrop of increasingly tight energy supplies and ever-increasing environmental protection requirements, how to effectively utilize natural energy sources (such as wind and solar power) at tunnel exits to power road infrastructure has become a current research hotspot. However, existing road infrastructure suffers from problems such as dispersed structure, low integration, and low energy conversion efficiency in energy utilization, making it difficult to achieve efficient energy utilization and integrated operation of equipment. Utility Model Content

This device can not only effectively absorb vehicle impact energy and reduce the harm of traffic accidents, but also make full use of wind and solar energy at the tunnel exit to generate electricity and provide green energy for road facilities.

[0005] The objective of this utility model is mainly achieved through the following solution:

[0006] The integrated photovoltaic guardrail anti-collision device at the tunnel exit includes an anti-collision pier body. An anti-collision mechanism is provided on the side of the anti-collision pier body facing the center of the road. A wind power generation mechanism and a solar power generation mechanism are arranged sequentially above the anti-collision pier body.

The end of the narrowing part is inserted into the inside of the fixed cylinder, and the end of the narrowing part is provided with a limiting block that matches the inner side wall of the fixed cylinder.

[0008] Preferably, the buffer assembly includes a fixed block, a sliding block, a fixed post, a linkage rod, and a second buffer spring.

The two sliding blocks are slidably connected to the outer wall of the fixed post. The second buffer spring is sleeved on the outer wall of the fixed post, and both ends of the second buffer spring are in contact with the inner walls of the two sliding blocks. One end of the two linkage rods is movably connected to one side of the two sliding blocks, and the other end of the two linkage rods is movably connected to the side wall of the anti-collision cylinder.

[0009] Preferably, the anti-collision cylinder is provided with an elastic energy-absorbing layer, a buffer layer and an impact-resistant layer from the inside to the outside.

[0010] Preferably, the wind power generation mechanism is a vertical axis wind turbine.

[0011] Preferably, the solar power generation mechanism is fixedly installed on the top of the wind power generation mechanism, including a support rod, a support frame, and a photovoltaic panel installed on the support frame.

[0014] In summary, compared with the prior art, the present invention has the following beneficial technical effects:

[0015] (1) This utility model, through the combination of anti-collision mechanism, telescopic component and buffer component, can effectively absorb and disperse the energy generated when the vehicle hits. When the vehicle hits the anti-collision cylinder, the anti-collision cylinder pushes the telescopic rod to compress the first buffer spring. At the same time, the sliding block is driven to slide on the fixed column through the linkage rod to compress the second buffer spring. The multi-level buffer structure greatly reduces the impact force of the vehicle and reduces the damage to vehicles and people caused by traffic accidents.

[0016] (2) This utility model device integrates a wind power generation mechanism and a solar power generation mechanism, making full use of the wind and solar energy at the tunnel exit to generate electricity. The vertical axis wind turbine can make full use of the relatively stable wind power generated by the traffic flow on the highway to generate electricity stably. The solar power generation mechanism can adjust the angle of the photovoltaic panel through the first adjustment component and the second adjustment component to improve the absorption efficiency of solar energy, provide green energy for road lighting, monitoring and other facilities, reduce the dependence on the traditional power grid, and achieve energy conservation and emission reduction.

[0017] (3) This utility model integrates the anti-collision function with the new energy power generation function, which reduces the land area occupied by road facilities and improves the space utilization rate. At the same time, the components are closely connected and work together, which improves the overall stability and reliability of the device. Attached Figure Description

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0026] Example 1:

[0027] like Figure 1 , 2 As shown, this utility model discloses a technical solution: an integrated photovoltaic guardrail anti-collision device for tunnel exits, including an anti-collision pier body 1. The anti-collision pier body 1 is made of high-strength concrete and has an internal steel structure frame to ensure overall stability. An anti-collision mechanism is provided on the side of the anti-collision pier body 1 facing the center of the road. A wind power generation mechanism 2 and a solar power generation mechanism 3 are installed on the top of the anti-collision pier body 1 by bolts. The wind power generation mechanism 2 uses a vertical axis wind turbine, which can make full use of the relatively stable wind force generated by the traffic flow on the highway to generate stable power.

[0028] The aforementioned anti-collision mechanism includes an anti-collision cylinder 4 parallel to the length of the road. Both ends of the anti-collision cylinder 4 are movably connected to telescopic components. The other end of the telescopic components is fixedly connected to the side wall of the anti-collision block body 1. A buffer component is also installed between the two telescopic components, and the buffer component is movably connected to the side wall of the anti-collision cylinder 4. When a vehicle hits the anti-collision cylinder 4, the anti-collision cylinder 4 pushes the telescopic components to compress, while the buffer component provides cushioning. The multi-stage buffer structure greatly reduces the impact force of the vehicle and reduces the damage to vehicles and people caused by traffic accidents.

[0029] Example 2:

[0030] like Figure 3 , 4 As shown, this utility model discloses another technical solution: an integrated anti-collision device for photovoltaic guardrails at tunnel exits. The difference from embodiment 1 is that the above-mentioned telescopic component includes a fixed cylinder 5, a telescopic rod 6, and a first buffer spring 7. The fixed cylinder 5 is hollow inside and open on one side. The closed end of the fixed cylinder 5 is fixedly connected to the side wall of the anti-collision block body 1 by bolts. One end of the telescopic rod 6 is provided with a coaxial reduction part 8. The other end of the telescopic rod 6 is rotatably connected to the anti-collision cylinder 4 by a rotating shaft. The first buffer spring 7 is sleeved on the outer side wall of the reduction part 8. The end of the reduction part 8 is inserted into the interior of the fixed cylinder 5. The end of the reduction part 8 is integrally provided with a limiting block 9 that is adapted to the inner side wall of the fixed cylinder 5. The limiting block 9 prevents the telescopic rod 6 from completely coming out. When the first buffer spring 7 is impacted, it first undergoes compression deformation to absorb the initial impact energy.

[0031] Specifically, the buffer assembly includes a fixed block 10, a sliding block 11, a fixed post 12, a linkage rod 13, and a second buffer spring 14. Two sets of fixed blocks 10, sliding blocks 11, and linkage rods 13 are provided. The two fixed blocks 10 are located between two fixed cylinders 5.

The two ends of the second buffer spring 14 are in contact with the inner sidewalls of the two sliding blocks 11 respectively. One end of the two linkage rods 13 is rotatably connected to one side of the two sliding blocks 11 through a rotating shaft. The other end of the two linkage rods 13 is rotatably connected to the sidewall of the anti-collision cylinder 4 through a rotating shaft. When the anti-collision cylinder 4 is impacted, the linkage rods 13 push the two sliding blocks 11 to move, compressing the second buffer spring 14 to form a second-level buffer. At the same time, the first buffer spring 7 in the telescopic assembly is also compressed synchronously, forming a multi-level energy absorption mechanism.

[0032] Specifically, the anti-collision cylinder 4 is provided with an elastic energy-absorbing layer, a buffer layer and an impact-resistant layer from the inside out. The inner layer is a polyurethane foam elastic energy-absorbing layer, the middle layer is a rubber buffer layer and the outer layer is a fiberglass impact-resistant layer. This structure can effectively absorb and disperse collision energy.

The difference from Embodiment 1 is that the aforementioned solar power generation mechanism 3 is bolted to the top of the wind power generation mechanism 2, including a support rod 15, a support frame 16, and a photovoltaic panel 17 mounted on the support frame 16. An adjusting rod 18 is rotatably connected to the top of the support rod 15, and the middle of the adjusting rod 18 is connected to the support rod 15 via a rotating shaft. A first adjusting component is provided between the adjusting rod 18 and the support rod 15. The support frame 16 is rotatably connected to the adjusting rod 18, and the upper, middle, and lower positions of the adjusting rod 18 are all connected to the support frame 16 via rotating shafts. A second adjusting component is provided between the support frame 16 and the adjusting rod 18. The first and second adjusting components respectively adjust the angles of the support frame 16 and the photovoltaic panel 17 in the vertical and horizontal directions.

[0035] Specifically, the first adjustment assembly includes a first adjustment column 19 and a first locking sleeve 20. The upper part of the first adjustment column 19 is rotatably connected to the side wall of the adjustment rod 18 via a rotating shaft. The lower end of the first adjustment column 19 is inserted into the first locking sleeve 20. The side wall of the first locking sleeve 20 is rotatably connected to the top of the support rod 15 via a rotating shaft. The first adjustment column 19 is fixedly installed in the first locking sleeve 20 by a locking bolt.

[0036] Specifically, the second adjustment component includes a second adjustment column 21 and a second locking sleeve 22. One end of the second adjustment column 21 is rotatably connected to the support frame 16 via a rotating shaft, and the other end of the second adjustment column 21 is inserted into the second locking sleeve 22. The side wall of the second locking sleeve 22 is rotatably connected to the top side of the adjustment rod 18 via a rotating shaft. The second adjustment column 21 is fixedly installed in the second locking sleeve 22 by locking bolts.

[0037] Highway maintenance personnel can adjust the angle of the photovoltaic panel 17 using the first and second adjustment components to optimize power generation efficiency based on seasonal and daily changes in the sun's position.
