Description
A photovoltaic foundation device for the sunny side of a highway slope. 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 the sunny side of a highway slope. Background Technology
[0002] Highway slopes, as linear unused spaces, are gradually becoming an important potential application scenario for photovoltaic power generation. Compared with conventional flat sites, the construction of photovoltaic systems on highway slopes needs to simultaneously consider multiple requirements such as slope stability, highway operation safety, and long-term reliability of the photovoltaic system, which poses various challenges to traditional photovoltaic support technology.
[0003] Currently, there are three common types of photovoltaic support devices used in the construction of photovoltaic systems on highway slopes: (1) photovoltaic support devices made of cement counterweight blocks; (2) photovoltaic support devices made of micro-hole grouting piles; and (3) photovoltaic support devices made of helical piles.
[0004] The above three types of photovoltaic foundation devices each have the following drawbacks:
[0005] (1) After the highway is completed and put into use, if the slope is reconstructed, there is a risk of lateral slippage due to the operation on the slope. 2. The construction of cement pillars or micro-hole cast-in-place piles will have a certain impact on the roadbed and damage it. 3. During the friction between the helical piles and the gravel of the roadbed, the galvanized layer of the helical piles will be damaged, and it cannot be guaranteed that the helical piles will not break for 25 years.
[0006] Therefore, it is evident that the existing photovoltaic foundations for highway slopes still have inconveniences and shortcomings in terms of structure, methods, and use, and urgently need further improvement. How to create a new photovoltaic foundation device for the sunny side of highway slopes that is structurally stable and durable while avoiding damage to the roadbed and mitigating the risk of lateral slippage during slope operations has become a pressing goal for the industry. Summary of the Invention

The prefabricated anti-slip base plate, the highway crash barrier, and the prefabricated photovoltaic foundation piers are prefabricated integral structures for simultaneous construction and installation with the highway slope. The prefabricated anti-slip base plate is completely buried underground, and the lower parts of the highway crash barrier and the prefabricated photovoltaic foundation piers are also buried underground.

[0016] 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.

[0018] Furthermore, the upper part of the prefabricated photovoltaic foundation pier has reserved holes for cable channels, which are used to thread through the special cables for connecting photovoltaic panel modules.

Detailed Implementation
[0029] 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.
[0030] This embodiment provides a photovoltaic foundation device for the sunny side slope of a highway. In the early stages of highway construction, for road sections where photovoltaic installation is required or suitable, a prefabricated, integrally formed photovoltaic foundation device is constructed according to the width and length required for photovoltaic installation on the south side of the east-west highway when laying the roadbed.
[0031] As shown in Figures 1 and 2, the photovoltaic foundation device provided in this embodiment includes a prefabricated foundation anti-slip base plate 1, highway crash barriers 2, and prefabricated photovoltaic foundation piers 3. The prefabricated foundation anti-slip base plate 1 serves as the foundation plate for the entire photovoltaic foundation device, providing stability and anti-slip protection. Preferably, the bottom surface of the prefabricated foundation anti-slip base plate 1 contains multiple downward-facing anti-slip columnar protrusions 11, which are firmly bonded to the slope subgrade, greatly enhancing the anti-slip and stability effect. The highway crash barriers 2 are located on one side of the prefabricated foundation anti-slip base plate 1 (the side closest to the highway), providing a certain buffer for vehicles involved in traffic accidents. The highway crash barriers 2 can be arranged in multiple intervals along one side of the prefabricated foundation anti-slip base plate 1, or they can be an integrated crash barrier structure. Furthermore, along the slope width direction, the highway crash barriers 2 have a narrower top and wider bottom structure, which reduces material usage while maintaining a stable structure. Multiple prefabricated photovoltaic foundation piers 3 are respectively installed on the prefabricated foundation anti-slip base plate, forming a square array.
[0032] The precast anti-slip base plate 1, highway crash barriers 2, and precast photovoltaic foundation piers 3 in the aforementioned photovoltaic foundation device are precast integral structures, such as cement or concrete cast-in-place precast integral structures. Because the photovoltaic foundation device adopts an integral structure, it can be constructed and installed simultaneously with the highway slope. During construction and installation, the precast anti-slip base plate 1 is completely buried underground, and the lower parts of the highway crash barriers 2 and precast photovoltaic foundation piers 3 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 3, every four prefabricated photovoltaic foundation piers 3 support one photovoltaic panel module 4. Along the width of the slope, 2-4 rows of photovoltaic panel modules 4 are installed according to installation needs, and the height of the prefabricated photovoltaic foundation piers 3 gradually decreases along the slope width, providing inclined support for the photovoltaic panel modules 4. Along the length of the slope, 3-10 rows of photovoltaic panel modules 4 can be installed according to installation needs. When the length is longer, multiple sets of photovoltaic foundation devices can be installed separately. To improve the utilization rate of the prefabricated photovoltaic foundation piers 3, a design method is adopted where adjacent photovoltaic panel modules 4 share the prefabricated photovoltaic foundation piers 3.
[0034] Each photovoltaic (PV) foundation precast pier 3 has a component clamping block 5 at its top, which is connected to the PV foundation precast pier 3 via a component clamping block embedded part 6. The component clamping block 5 is mainly used to fix the PV panel module 4. The component clamping block embedded part 6 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 PV foundation precast pier 3, and the top of the inverted U-shaped structure is connected to the component clamping block 5. The component clamping block embedded part 6 adopts the form of an embedded part and a special structural setting, which is more stable than the traditional PV bracket clamping block fixing. Each PV foundation precast pier 3 has two component clamping blocks 5 at its top, so there are eight fixing points on a PV panel module 4. Compared with the conventional form with only four fixing points, this can prevent damage and falling of the PV panel module 4 frame due to the failure of a component clamping block 5 in extreme weather, and prevent the PV panel module 4 from being blown up by strong winds and causing traffic accidents with vehicles traveling on the highway.
[0035] Drainage holes 7 are pre-installed on both the highway crash barrier 2 and the precast photovoltaic foundation pier 3, with the drainage holes 7 oriented along the width of the slope. The drainage holes 7 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 7 on the highway crash barrier 2 are horizontally positioned along the width of the slope, with the bottom edge of the drainage holes 7 flush with the highway surface 9; this arrangement allows water accumulated on the highway surface 9 to flow smoothly into the drainage holes 7 and be directly discharged onto the slope, preventing water accumulation on the road surface from affecting driving safety.
[0036] The drainage holes 7 on the precast photovoltaic foundation piers 3 are inclined along the width of the slope, and the drainage holes 7 on adjacent precast photovoltaic foundation piers 3 are staggered vertically along the same width. This inclined arrangement of the drainage holes 7 helps to accelerate the drainage of accumulated water using gravity, improving drainage efficiency. Furthermore, the staggered arrangement of the drainage holes 7 on adjacent precast photovoltaic foundation piers 3 avoids the problem of excessive water flow in localized areas due to multiple drainage holes 7 concentrating on drainage, 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 3, and thus ensuring the stability of the photovoltaic facility foundation.
[0037] The precast pier 3 of the photovoltaic foundation has reserved cable channels and reserved holes 8 on the upper part, which are used to connect the special cables for photovoltaic panel modules to prevent electric shock injuries 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 adopts a prefabricated integrated structure of prefabricated foundation anti-slip base plate, highway anti-collision block and photovoltaic foundation prefabricated block. It can be carried out simultaneously with highway construction, avoiding damage to the roadbed and its impact. It can also avoid the risk of lateral slippage when working on slopes after the highway is completed and put into use. It also has the advantages of stable and durable structure, and is suitable for widespread application.
[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.
