Description

A concrete assembled photovoltaic support landscape foundation structure

Technical Field

The utility model relates to a photovoltaic support structure, and more specifically, to a concrete assembled photovoltaic support landscape foundation structure.

Background Art

In large-scale ground photovoltaic power stations, concrete strip foundations are still one of the mainstream foundation types, suitable for large areas with relatively flat sites. However, strip foundations placed on the ground often use a large amount of concrete. For areas with increased basic wind pressure, the foundation volume is large and often needs to be cast in place, which increases construction costs and construction period. At the same time, the large use of concrete is relatively not green and environmentally friendly.

For example: China Patent Publication No. CN211898516U, the publication date is November 10, 2020, and the name of the utility model is A movable photovoltaic panel foundation structure for fly ash sites. The application discloses a photovoltaic panel foundation structure, including a photovoltaic panel foundation body, on which a lifting ring device is provided. The lifting ring device includes a fixed handle, a sleeve and a ring. The application can solve the problem of inconvenient transportation of the photovoltaic panel foundation, but the photovoltaic panel foundation in this scheme is cast in concrete, which increases the construction cost and construction period, and is not green and environmentally friendly.

Utility Model Content

The utility model overcomes the problems of high construction cost and long construction period of the existing photovoltaic panel foundation, and provides a concrete assembled photovoltaic bracket landscape foundation structure. This scheme can reduce the construction cost and construction period of the photovoltaic panel foundation, and can realize the rapid layout of the photovoltaic foundation.

In order to solve the above technical problems, the utility model adopts the following technical solutions: a concrete assembled photovoltaic support landscape foundation structure, including an assembled foundation, the assembled foundation including a bottom plate, the bottom plate is surrounded by a side plate to form a receiving cavity, and a filler is provided in the receiving cavity. The assembled foundation is a detachable structure, and the receiving cavity is formed by assembling the bottom plate and the side plate. The filling object inside the receiving cavity makes the assembled foundation have a certain weight, so as to achieve a load-bearing effect and prevent the photovoltaic panel from being blown over by the wind. This solution greatly improves the construction and installation efficiency of the photovoltaic foundation, shortens the construction period, and reduces the use of concrete, thereby reducing construction costs.

Preferably, a plurality of first embedded anchor bolts are arranged on the sides of the bottom plate, and the bottom plate and the side plate are detachably connected through the first embedded anchor bolts. The first embedded anchor bolts are arranged around the bottom plate, and the bottom plate and the side plate are directly fixedly connected through the first embedded anchor bolts. The modular structure of the bottom plate and the side plate can be prefabricated in advance, and only the modules need to be assembled through the first embedded anchor bolts at the construction site, which not only improves the construction and installation efficiency, but also reduces the labor intensity.

Preferably, the fabricated foundation is a strip foundation, and at least two piers are provided in the length direction of the accommodating cavity. A bracket needs to be installed on the fabricated foundation, and the bracket is connected to the fabricated foundation through the piers. At least two piers are required to ensure that the bracket can be stably installed on the fabricated foundation.

Preferably, the pier is detachably connected to the bottom plate via a second embedded anchor bolt. The pier is located in the accommodating cavity and is directly connected to the bottom plate. The second embedded anchor bolt is arranged on the floor, which can realize the rapid connection and fixation of the pier and improve the construction efficiency. At the same time, the second embedded anchor bolt can also position the pier to prevent the position of the pier from changing, so that the photovoltaic bracket and the photovoltaic panel can work normally.

Preferably, a plurality of the assembled foundations are arranged side by side at intervals to form a photovoltaic foundation assembly, and a photovoltaic bracket is arranged on the photovoltaic foundation assembly. In a photovoltaic power station, the site is generally a relatively flat large area, and the assembled foundations are arranged side by side at intervals to form a photovoltaic foundation assembly, and photovoltaic brackets are arranged on the photovoltaic foundation assembly to form a larger photovoltaic power generation facility, thereby improving the stability and efficiency of the photovoltaic foundation.

Preferably, the photovoltaic support is arranged at an angle, and a photovoltaic panel is provided on the photovoltaic support. The photovoltaic panel on the photovoltaic support is used for generating electricity.

Preferably, the height of the pier does not exceed the height of the side panel, and the filling height of the filler is not less than the height of the pier. The photovoltaic bracket is directly connected to the pier. If the height of the pier is too high, the overall height of the bracket will be higher, and the center of gravity will be higher, and the stability will be poor. Therefore, it is more appropriate that the height of the pier does not exceed the height of the side panel; at the same time, the height of the filler can be made higher than the height of the pier. If the height of the filler is higher than the pier, the part higher than the pier will bury the photovoltaic bracket connected to the pier, which in disguise reduces the height of the bracket, reduces the center of gravity of the bracket, and improves stability. The pier is inside the filler, which can also make the position of the pier less likely to move.

Preferably, the filler is soil, rock, mud and sand. The filler is soil, rock, mud and sand, which can provide a growth environment for plants.

Preferably, green plants are arranged in the filler, which are plants with low light requirements, can be used as landscapes for decoration, and also embody the concept of green environmental protection.

Compared with the prior art, the beneficial effects of the present invention are: (1) the assembled photovoltaic foundation can improve the construction difficulty and construction period of the photovoltaic foundation, and improve the construction efficiency; (2) the use of concrete is reduced, reducing the construction cost; (3) green and environmentally friendly plants are set up to improve the aesthetics of the photovoltaic station, which is in line with the green concept.
