Description
Technical Field
[0001] This utility model relates to the field of box-type transformer technology, and specifically to a suspended foundation platform for a photovoltaic box-type transformer. Background Technology
[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect at the semiconductor interface to directly convert light energy into electrical energy. However, the construction of photovoltaic power plants requires a large amount of land, which has led to the emergence of the agricultural-photovoltaic complementary model. The agricultural-photovoltaic complementary model is a composite project model that achieves efficient resource utilization by superimposing photovoltaic power generation and agricultural production on the same land space. Its core feature is the three-dimensional development form of "power generation on the panel and planting under the panel".
[0003] Under the existing agricultural-solar complementary model, although crops can be planted under the photovoltaic panels, many box-type transformers need to be installed in the photovoltaic power plant according to the amount of power generation. The foundation platform for installing the box-type transformers mostly needs to be excavated in the ground for grounding and bedding layer construction, followed by concrete pouring. This not only makes the construction slow but also occupies a large amount of land area, wasting land resources. In addition, the lower part of the box-type transformer is very close to the ground, which limits the heat dissipation of the lower part. Utility Model Content
[0004] The purpose of this utility model is to provide a suspended foundation platform for a photovoltaic box-type transformer to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a suspended foundation platform for a photovoltaic box-type transformer, comprising grouting piles, support columns, and a suspended platform. The grouting piles and support columns correspond one-to-one. The grouting piles are set below the ground, and the support columns are installed above the grouting piles. The suspended platform is set above the support columns. The upper part of the suspended platform is used to install the box-type transformer. The suspended platform includes a hollow platform, a support platform, and iron grating. The support platform is set above the hollow platform. The hollow platform and the support platform are respectively provided with a first ventilation window and a second ventilation window in their middle parts. The positions of the first ventilation window and the second ventilation window correspond. An iron grating is installed at the bottom of the first ventilation window.
