[0002] Currently, energy storage systems in the form of containerized, prefabricated, or outdoor cabinets are typically installed on concrete foundations (independent or strip foundations). This method has a long construction period, requires on-site pouring and curing, and causes serious damage to the site environment. In addition, traditional foundations require the excavation of a large amount of earthwork and ground hardening, leaving behind non-recyclable engineering remnants, increasing project costs, and potentially requiring land acquisition permits and other procedures.

It can be completely disassembled and removed when the service life ends or when relocation is required, without causing environmental pollution, damaging the ground, or leaving any permanent structures. In addition, the installation of helical piles causes little disturbance to the ground surface, which can reduce the need for construction land indicators and land acquisition permits, thereby reducing related approval work and project costs. At the same time, it can be constructed quickly during the installation process without the need for concrete pouring and curing, which significantly shortens the installation cycle.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an installation structure for a rapidly detachable and recyclable energy storage system based on a helical pile, comprising a helical pile and a pile body driven into the ground at the tail of the helical pile; an installation assembly that can be connected to the top of the helical pile and an extension assembly connected to the top of the installation assembly; the installation assembly includes a second flange screwed to the helical pile, and an adjustment seat that can extend into the interior of the helical pile is provided on the second flange; the extension assembly includes an extension column screwed to the second flange, and a fourth flange is provided on the top of the extension column.

[0010] Optionally, the bottom of the extended column is provided with a third flange that is bolted to the second flange.

[0011] Compared with the prior art, the beneficial effects of this utility model are: based on the overall structure and total weight of the energy storage system, the center of gravity of the energy storage system is calculated, and the reasonable number and distribution of the helical piles are designed to make the foundation bearing stable and reliable; the helical piles are made of high-strength metal material and are firmly connected to the ground, which can be used as the system grounding body to realize the equipment grounding function without the need for a separate grounding grid or grounding rod.

[0012] When the energy storage system reaches the end of its service life or needs to be relocated, it can be completely disassembled and removed without causing environmental pollution, damaging the ground, or leaving any permanent structures.
