However, during the technical transformation process, that is, during the installation of the supercapacitor module, the bolt fixing position in the battery cabinet does not match the reserved position of the bolt hole of the modified supercapacitor module, making it inconvenient to install the supercapacitor module. If the entire battery cabinet is replaced, there will be a risk of high cost and large engineering workload, and even affecting the power generation of the unit. Therefore, after research, a fixing device for facilitating the installation of the supercapacitor module of a wind turbine is provided. When in use, the size of the back plate is designed according to the size of the original battery cabinet, and the fixing bolts installed by the original battery pack are used to fix the back plate.
