Description

Technical Field

[0001] This invention relates to a comprehensive protection system for highway slopes, belonging to the field of highway slope protection technology. Background Technology

[0002] As an important ancillary structure of road engineering, highway slopes are subject to long-term rainwater erosion and runoff, making them prone to disasters such as slope collapse, soil erosion, and vegetation destruction. This not only affects slope stability but may also cause safety hazards such as rockfall and roadbed damage. Current highway slope protection methods, such as masonry, frame beams, and grass planting, can only achieve passive protection and cannot effectively collect and guide rainwater runoff. The disorderly erosion of rainwater along the slope is still difficult to avoid, and the problem of slope erosion persists.

[0003] Meanwhile, in the context of driving on highways at night, drivers are prone to fatigue due to monotonous vision and relaxed concentration, which is a major cause of traffic accidents. Conventional anti-fatigue laser warning lights mostly rely on municipal power grids for power supply, which has problems such as complex wiring, high energy consumption, inconvenient power supply in remote road sections, and high maintenance costs, making it difficult to widely apply them along mountainous highways.

[0004] Furthermore, highways have open and long spatial resources, and the slope areas have good sunlight conditions, which are natural advantages for solar energy utilization. In the existing technology, the deployment of solar photovoltaic on slopes only considers photovoltaic power generation, which is a single function and is not integrated with slope drainage, slope protection, and fatigue warning. Drainage ditches and solar photovoltaic panels are independent of each other, which cannot realize the synergistic effect of rainwater diversion, erosion reduction and collection and drainage. This leads to redundant engineering structure, complicated construction, inefficient use of photovoltaic power, and low overall benefits.

[0005] In summary, existing highway slope protection suffers from technical defects such as poor rainwater erosion resistance, disconnect between drainage systems and photovoltaic facilities, and inconvenient power supply for fatigue warning facilities in mountainous sections. There is an urgent need for an integrated slope protection technology solution that integrates photovoltaic deployment, rainwater diversion and collection, and solar power supply for fatigue warning. Summary of the Invention

[0006] The purpose of this invention is to overcome the many defects in existing highway slope protection, drainage, solar energy utilization and fatigue warning technologies, and to provide a comprehensive protection system for highway slopes that integrates photovoltaic deployment, rainwater diversion and collection utilization, solar power supply and fatigue warning.

[0007] The technical solution of this invention is as follows:

[0008] A comprehensive protection system for highway slopes, including:

[0009] The drainage system includes interconnected transverse and longitudinal drainage ditches, which form a mesh structure and are anchored to the slope surface.

[0010] The solar energy system includes multiple photovoltaic panels, each photovoltaic panel being disposed in a single grid of the mesh structure, and is capable of diverting rainwater falling on the surface of the photovoltaic panels to the drainage system;

[0011] A water storage system is installed between the bottom of the slope and the roadbed, and is connected to the drainage system to collect and store rainwater discharged by the drainage system.

[0012] As a preferred embodiment of the present invention, it further includes a warning system powered by a solar energy system, the warning system comprising an anti-fatigue laser warning light and an information display device; the anti-fatigue laser warning light is located at the top of the slope and is used to emit laser beams into the air at night to form a light curtain; the information display device is communicatively connected to an external control center and is used to issue warning information to passing vehicles.

[0013] As a preferred embodiment of the present invention, the solar energy system further includes an energy storage device, the photovoltaic panel is electrically connected to the energy storage device, and the energy storage device is used to store the electrical energy generated by the photovoltaic panel and supply power to the warning system.

[0014] As a preferred embodiment of the present invention, the bottom end of the photovoltaic panel is hinged to the corresponding grid edge, and the top and both sides of the photovoltaic panel are covered with flexible buffer material, which is used to make contact with the corresponding grid edge.

[0015] As a preferred embodiment of the present invention, a two-section support arm is provided at the bottom of the photovoltaic panel, and a support base is provided within the grid. One end of the two-section support arm is hinged to the support base, and the other end is hinged to the bottom of the photovoltaic panel.

[0016] As a preferred embodiment of the present invention, the rotating shaft used in the two-section support arm is a damped rotating shaft.

[0017] As a preferred embodiment of the present invention, the mesh structure is arranged in a continuous trapezoidal shape from the bottom of the slope to the top of the slope; the longitudinal drainage ditch is located between two adjacent transverse drainage ditches to achieve the connection between the transverse drainage ditches; the longitudinal drainage ditches arranged on both sides of each transverse drainage ditch are staggered.

[0018] As a preferred embodiment of the present invention, the water storage system includes a plurality of rainwater wells arranged in sequence, with adjacent rainwater wells interconnected, and each longitudinal drainage ditch located at the bottom of the slope corresponding to a rainwater well. The water in the rainwater wells is used for cleaning photovoltaic panels, greening irrigation, and forest fire fighting.

[0019] As a preferred embodiment of the present invention, a partition is provided inside the rainwater well, which divides the interior of the rainwater well into a sewage chamber and a clean water chamber. The sewage chamber is connected to a longitudinal drainage ditch. Multiple through holes are provided on the partition near the top of the rainwater well, through which the upper clean water in the sewage chamber flows into the clean water chamber.

[0020] As a preferred embodiment of the present invention, an overflow outlet is provided at the top of the rainwater well, and a protective wall is provided at the edge of the road surface, wherein the space between the protective wall and the slope constitutes a rainwater overflow channel.

[0021] The advantages of this invention are:

[0022] This invention utilizes transverse and longitudinal drainage ditches anchored to the slope surface to form a basic protective beam. The resulting mesh structure provides overall protection for the slope, achieving both slope reinforcement and rainwater drainage. Solar photovoltaic panels are installed within individual grids of the mesh structure, covering the slope surface within each grid and guiding rainwater to the drainage ditches. This eliminates exposed slope surfaces, reducing rainwater runoff and erosion, mitigating the risks of slope erosion, landslides, and soil loss, and enhancing slope stability and durability. The design of the solar photovoltaic panels and drainage ditches is integrated with… Construction is streamlined, reducing repetitive work and structural redundancy, minimizing slope disturbance, and enhancing the project's economic efficiency and feasibility. The design incorporates rainwater wells to collect and store rainwater discharged from drainage ditches. This collected rainwater can be used for highway greening irrigation, reducing the need for transporting water from distant locations for road maintenance. Additionally, the collected rainwater can be used for forest fire fighting in mountainous areas or for cleaning solar photovoltaic panels. The anti-fatigue laser warning lights and information display devices are powered by solar energy, eliminating reliance on mains power. This simplifies wiring, facilitates construction, and reduces maintenance costs, making them particularly suitable for remote highway sections and mountainous areas without mains power lines.

It can not only meet the requirements of slope protection engineering, but also collect rainwater for secondary use, and utilize the slope space for photovoltaic power generation, and improve the driving safety conditions at night in mountainous areas through photovoltaic power.

[0036] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0037] like Figures 1 to 5 As shown, this embodiment provides a comprehensive protection system suitable for highway slopes, including a drainage system, a solar energy system, a water storage system, and a warning system. The drainage system includes interconnected transverse drainage ditches 1 and longitudinal drainage ditches 2, which form a mesh structure and are anchored on the slope surface to provide overall protection for the slope. The solar energy system includes an energy storage device and multiple photovoltaic panels 3. The photovoltaic panels 3 are electrically connected to the energy storage device, which stores the electrical energy generated by the photovoltaic panels 3 and supplies power to the warning system. Each photovoltaic panel 3 is correspondingly set in a single grid of the mesh structure and can guide rainwater falling on the surface of the photovoltaic panel 3 to the drainage system. The water storage system is located between the bottom of the slope and the roadbed 4 and is connected to the drainage system to collect and store rainwater discharged by the drainage system.

[0038] The warning system includes an anti-fatigue laser warning light 5 and an information display device 6. The anti-fatigue laser warning light 5 is installed at the top of the slope and is used to emit laser beams into the air at night to form a light curtain. The changes in light stimulate the senses of drivers of passing vehicles, breaking the fatigue state and activating the brain's alertness. The information display device 6 is connected to an external control center and is used to issue warning information to passing vehicles so as to promptly convey information such as weather conditions, road conditions, and traffic conditions to passing vehicles. In this embodiment, the information display device 6 is a text display screen, which is installed on a gantry on the highway.

[0039] An energy storage station 7 is set up at a suitable location on the slope or mountain, and the energy storage device is installed in the energy storage station 7; a cable conduit 8 is buried on the slope, and the cable connecting the photovoltaic panel 3 and the energy storage device is run through the cable conduit 8; in practical applications, the energy storage device can also be used to supply power to power equipment such as highway monitoring equipment and speed measuring equipment.

[0040] To facilitate maintenance and repair of photovoltaic panel 3, the bottom end of photovoltaic panel 3 is hinged to the corresponding grid edge, specifically, as shown in... Figure 3 As shown, a rotating shaft is provided at the bottom of the photovoltaic panel 3, and a groove is provided at the corresponding grid edge. Bearing seats are embedded in the side walls at both ends of the groove. The two ends of the rotating shaft are rotatably connected to the bearing seats on the side walls at both ends of the groove. When lifting the photovoltaic panel 3, a suction cup is used to hold the free end of the photovoltaic panel 3, and then the photovoltaic panel 3 is pulled up. The photovoltaic panel 3 rotates around the rotating shaft and is lifted upward. Then, a support tool is used to support the photovoltaic panel 3. At this time, maintenance personnel can inspect the electrical circuits on the back of the photovoltaic panel 3.

[0041] To further improve the convenience of maintenance and repair, so that operators do not need to carry support tools, in some embodiments, a two-section support arm 9 is set at the bottom of the photovoltaic panel 3, and a support base 10 is set in the grid. One end of the two-section support arm 9 is hinged to the support base 10, and the other end is hinged to the bottom of the photovoltaic panel 3. The rotation axis used by the two-section support arm 9 is a damped rotation axis, so as to achieve the function of stopping at any support position.

[0042] In some embodiments, the top and side ends of the photovoltaic panel 3 are covered with flexible buffer material 11, and the flexible buffer material 11 is in contact with the corresponding grid edge. The flexible buffer material 11 plays a role in vibration damping and buffering, preventing the end of the photovoltaic panel 3 from making hard contact with the grid edge. At the same time, it can also fill the gap between the end of the photovoltaic panel 3 and the grid edge, reducing the inflow of rainwater into the grid. The flexible buffer material 11 is made of weather-resistant rubber, such as EPDM (ethylene propylene diene monomer rubber).

[0043] In some embodiments, the mesh structure is arranged in a continuous trapezoidal shape from the bottom of the slope to the top of the slope to achieve better stability of the slope protection structure; the longitudinal drainage ditch 2 is set between two adjacent transverse drainage ditches 1 to realize the connection between the transverse drainage ditches 1; the longitudinal drainage ditches 2 arranged on both sides of each transverse drainage ditch 1 are staggered to reduce the water flow impact force generated by the longitudinal drainage water flowing down the slope, and reduce the scouring and damage of the water flow to the drainage system and the water storage system at the bottom of the slope.

[0044] like Figure 4 As shown, the water storage system includes multiple rainwater wells 20 arranged in sequence. Adjacent rainwater wells 20 are interconnected by a connecting pipe 21. Each longitudinal drainage ditch 2 located at the bottom of the slope is connected to a corresponding rainwater well 20. The water in the rainwater wells 20 can be used for irrigation of highway greening, reducing the need to transport water from distant places for road maintenance. At the same time, the water in the rainwater wells 20 can also be used for fire fighting in mountain forests or for cleaning photovoltaic panels 3. A partition 22 is installed inside the rainwater well 20, which divides the interior of the rainwater well 20 into a sewage chamber 23 and a clear water chamber 24. The sewage chamber 23 is connected to the longitudinal drainage ditch 2. Multiple through holes 25 are provided on the partition 22 near the top of the rainwater well 20, through which the upper clear water in the sewage chamber 23 flows into the clear water chamber 24.

[0045] During rainfall, rainwater flows into the sewage chamber 23 through the longitudinal drainage ditch 2. Debris such as dead branches, leaves, gravel, and soil carried in the rainwater settles in the sewage chamber 23. The clear water in the sewage chamber 23 flows into the clear water chamber 24 through the through holes 25 on the partition 22. The through holes 25 on the partition 22 form a simple filtration function, and some floating objects in the water are intercepted by the through holes 25 on the partition 22.

[0046] An overflow outlet 26 is provided at the top of the rainwater well 20 for overflowing when the well 20 is full. In this embodiment, two overflow outlets 26 are provided at the top of each rainwater well 20, corresponding to the sewage chamber 23 and the clear water chamber 24 respectively. A protective wall 12 is provided at the edge of the road surface, and the space between the protective wall 12 and the slope forms a rainwater overflow channel 27. The slope surface between two adjacent longitudinal drainage ditches 2 at the bottom of the slope is covered with reinforced concrete to ensure the unobstructed flow of the rainwater overflow channel 27. When rainwater in the rainwater well 20 overflows through the overflow outlet 26, the overflow... Rainwater is discharged through the rainwater overflow channel 27; the overflow outlet 26 is also used as a water intake, and the water intake pipe is inserted into the corresponding clean water chamber 24 or sewage chamber 23 through the overflow outlet 26, and then the water is pumped out using a dry pump; when the rainwater well 20 needs to be cleaned, it can also be entered through the overflow outlet 26, and a corresponding ladder is set in the rainwater well 20; in order to prevent animals or unrelated personnel from falling into the rainwater well 20, fences are set at the overflow outlet 26 and at the connection between the longitudinal drainage ditch 2 and the rainwater well 20, and the fence at the overflow outlet 26 is an openable fence.
