Description

A photovoltaic foundation device for actively preventing highway slope collapse Technical Field

[0001] This utility model relates to the field of photovoltaic technology for highway slopes, and in particular to a photovoltaic foundation device for actively preventing highway slope collapse. Background Technology

[0002] Highway slope monitoring is a crucial aspect of ensuring road traffic safety. Innovative applications of sensor technology can significantly improve monitoring efficiency and early warning capabilities. Current sensor-based monitoring and early warning technologies, such as pressure and displacement sensors, primarily rely on point-based monitoring, resulting in limited coverage, numerous blind spots, and performance degradation under adverse weather conditions. Furthermore, they cannot achieve full-area coverage, hindering comprehensive and timely monitoring and early warning of road accidents and slope collapses. Additionally, relying on a single sensor limits the monitoring range and prevents comprehensive, multi-faceted monitoring.

[0003] In addition, highway slopes, as linear idle spaces, are gradually becoming an important potential application scenario for photovoltaic power generation. Currently, photovoltaic brackets are commonly used to support photovoltaic panels in highway slope photovoltaic construction. There are generally three types of photovoltaic brackets: (1) photovoltaic brackets made of cement counterweights; (2) photovoltaic brackets made of micro-hole cast-in-place piles; and (3) photovoltaic brackets made of helical piles. The above photovoltaic brackets cannot guarantee the structural stability and durability while avoiding the risk of damaging the roadbed and slope operations.

[0004] It is evident that the existing highway slope collapse monitoring devices and photovoltaic supports have inconveniences and shortcomings, and urgently need further improvement. How to create a completely new active photovoltaic foundation device for preventing highway slope collapse, combining the functions of photovoltaic support and highway slope collapse monitoring, to proactively achieve foundation defense and comprehensive, timely monitoring and early warning, has become a pressing goal for the industry. Summary of the Invention

[0008] As a further improvement of this utility model, the sensor device also includes a video monitoring sensor; the video monitoring sensor is mounted on the highway crash barrier via a column, and the video monitoring sensor faces the highway surface.

[0009] Furthermore, a pressure sensor inspection port is provided on the prefabricated anti-slip base plate.

[0013] Furthermore, each photovoltaic foundation precast pier is equipped with two component pressing blocks at its top. The component pressing blocks are connected to the photovoltaic foundation precast pier through component pressing block embedded parts. The component pressing blocks are used to fix the photovoltaic panel components. The component pressing block embedded parts have an inverted U-shaped structure. The bottom of the inverted U-shaped structure is vertically connected to the inclined surface at the top of the photovoltaic foundation precast pier, and the top is connected to the component pressing blocks.

[0014] Furthermore, drainage holes are pre-reserved on the highway crash barriers and photovoltaic foundation precast piers, and the drainage holes are oriented along the width of the slope.

Detailed Implementation

[0026] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0027] As shown in Figures 1 and 2, this embodiment provides a photovoltaic foundation device for actively preventing highway slope collapse, including a prefabricated integrated photovoltaic support 1 and a sensor device 2 installed on the photovoltaic support 1.

[0028] Among them, the prefabricated integrated photovoltaic bracket 1 is constructed and installed at the same time as the road slope; if photovoltaics need to be installed in the early stage of road construction, or in a section that is more suitable for photovoltaic installation, the prefabricated integrated photovoltaic bracket is constructed according to the width and length of the photovoltaics to be installed on the side of the road when the roadbed is laid on the south side of the east-west road.

[0029] The prefabricated integrated photovoltaic support 1 includes a prefabricated foundation anti-slip base plate 11, a highway crash barrier 12, and a photovoltaic foundation prefabricated pier 13. The prefabricated foundation anti-slip base plate 11 serves as the foundation plate of the entire photovoltaic foundation device, playing a stabilizing and anti-slip role. The bottom surface of the prefabricated foundation anti-slip base plate 11 preferably contains multiple downward anti-slip columnar protrusions 111, which are firmly bonded to the slope subgrade, greatly improving the anti-slip and stabilizing effect. The highway crash barrier 12 is installed on one side of the precast foundation anti-slip base plate 11 (the side closest to the highway), which provides a certain buffer for vehicles involved in traffic accidents. The highway crash barrier 12 can be in the form of multiple barriers spaced along one side of the precast foundation anti-slip base plate 11, or it can be an integrated crash barrier structure. There are multiple photovoltaic foundation precast barriers 13, which are set on the precast foundation anti-slip base plate 11 to form an array. The precast integrated photovoltaic bracket 1 is used for construction and installation at the same time as the highway slope. The precast foundation anti-slip base plate 11 is completely buried underground, and the lower parts of the highway crash barrier 12 and the photovoltaic foundation precast barriers 13 are buried underground.

[0030] The sensor device 2 includes a pressure sensor 21, a static level 22, and a fixed tilt sensor 23. The pressure sensor 21 is installed at the bottom of the precast foundation anti-slip base plate 11 between the highway crash barrier 12 and the photovoltaic foundation precast pier 13, preferably near the side of the precast foundation anti-slip base plate 11 along the slope width direction. It will issue an early warning response when the pressure value from the upper road surface or the surrounding area changes. A pressure sensor inspection port 112 is provided on the precast foundation anti-slip base plate 11 to facilitate the calibration during the initial installation of the sensor and subsequent inspection and maintenance. The static level 22 is installed at the top of the photovoltaic foundation precast pier 13. There are two static levels 22, which are set at diagonally opposite positions in the array for vertical displacement monitoring. The fixed tilt sensor 23 is connected to the lower part of the precast foundation anti-slip base plate 11, preferably located in the middle of the side of the precast foundation anti-slip base plate 11 away from the highway side.

[0031] In order to monitor the road conditions, the sensor device 2 also includes a video monitoring sensor 24; the video monitoring sensor 24 is installed on the road crash barrier 12 via a column, such as a steel column, and the video monitoring sensor 24 faces the road surface.

[0032] In the aforementioned photovoltaic foundation device, the photovoltaic support 1 (including the prefabricated foundation anti-slip base plate 11, highway crash barriers 12, and prefabricated photovoltaic foundation piers 13) is a prefabricated integrated structure, such as a prefabricated integrated structure cast in cement or concrete. Because the photovoltaic support 1 adopts an integrated structure, it can be constructed and installed simultaneously with the highway slope. During construction and installation, the prefabricated foundation anti-slip base plate 11 is completely buried underground, and the lower parts of the highway crash barriers 12 and prefabricated photovoltaic foundation piers 13 are also buried underground. This design avoids damage to the roadbed and its impact, and also avoids the risk of lateral slippage during operations on slopes after the highway is completed and put into use. Furthermore, it has the advantages of a stable and durable structure.

[0033] In the array formed by the aforementioned prefabricated photovoltaic foundation piers 13, every four prefabricated photovoltaic foundation piers 13 support one photovoltaic panel module 14. Along the width of the slope, 2-4 rows of photovoltaic panel modules 14 are installed according to installation needs, and the height of the prefabricated photovoltaic foundation piers 13 gradually decreases along the slope width, providing inclined support for the photovoltaic panel modules 14. Along the length of the slope, 3-11 rows of photovoltaic panel modules 14 can be installed according to installation needs. When the length is longer, multiple sets of photovoltaic supports can be installed. To improve the utilization rate of the prefabricated photovoltaic foundation piers 13, a design method is adopted where adjacent photovoltaic panel modules 14 share the prefabricated photovoltaic foundation piers 13.

[0034] Each photovoltaic foundation precast pier 13 is topped with a module clamping block 15, which is connected to the photovoltaic foundation precast pier 13 via a module clamping block embedded part 16. The module clamping block 15 is mainly used to fix the photovoltaic panel module 14. The module clamping block embedded part 16 preferably adopts an inverted U-shaped structure; the bottom of the inverted U-shaped structure is perpendicularly connected to the inclined surface at the top of the photovoltaic foundation precast pier 13, and the top of the inverted U-shaped structure is connected to the module clamping block 15. The module clamping block embedded part 16 adopts the form of an embedded part and a special structural setting, which is more stable than the traditional photovoltaic bracket clamping block fixing. Each photovoltaic foundation precast pier 13 has two module clamping blocks 15 at its top, so there are eight fixing points on a photovoltaic panel module 14. Compared with the conventional form with only four fixing points, this can prevent damage and falling of the photovoltaic panel module 14 frame due to the failure of a module clamping block 15 in extreme weather, and prevent the photovoltaic panel module 14 from being blown up by strong winds and causing traffic accidents with vehicles traveling on the highway.

[0035] Drainage holes 17 are pre-installed on the highway crash barrier 12 and the precast photovoltaic foundation pier 13, with the drainage holes 17 oriented along the width of the slope. The drainage holes 17 effectively drain water and protect the structure; in rainy seasons, their drainage function can extend the service life of the photovoltaic foundation device and also protect the roadbed, preventing rainwater from affecting it and ensuring the safe and stable operation of the highway and photovoltaic facilities. Preferably, the drainage holes 17 on the highway crash barrier 12 are horizontally positioned along the width of the slope, with the bottom edge of the drainage holes 17 flush with the highway surface 19; this arrangement allows water accumulated on the highway surface 19 to flow smoothly into the drainage holes 17 and be directly discharged to the slope, preventing water accumulation on the road surface from affecting driving safety.

[0036] The drainage holes 17 on the precast photovoltaic foundation piers 13 are inclined along the width of the slope, and the drainage holes 17 on adjacent precast photovoltaic foundation piers 13 are staggered vertically along the width of the slope. The inclined drainage holes 17 help to accelerate the drainage of accumulated water using gravity, improving drainage efficiency. Furthermore, the staggered vertical arrangement of the drainage holes 17 on adjacent precast photovoltaic foundation piers 13 avoids the problem of excessive water flow in localized areas due to concentrated drainage from multiple drainage holes 17, which could cause scouring or water accumulation. This vertical staggering allows the accumulated water to be more evenly distributed during drainage, further ensuring the drainage effect of the entire slope area, effectively protecting the stability of the roadbed surrounding the precast photovoltaic foundation piers 13, and thus ensuring the stability of the photovoltaic facility foundation.

[0037] The prefabricated pier 13 of the photovoltaic foundation has a reserved cable channel and a reserved hole 18 on the upper part, which is used to connect the special cable for photovoltaic panel components to prevent electric shock injury to personnel caused by direct laying of wires, cables or cable trays in the event of a car accident.

[0038] In summary, the photovoltaic foundation device of this utility model installs multiple points and various types of sensor devices on a prefabricated integrated photovoltaic support. It can defend against slope collapse through a stable photovoltaic support, and at the same time, the sensor devices can provide timely early warning of slope collapse, thus proactively realizing basic defense and comprehensive and timely monitoring and early warning.

[0039] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes or alterations made by those skilled in the art using the above-disclosed technical content shall fall within the protection scope of the present utility model.
