This utility model discloses a spiral turbine generator for wind power generation, relating to the field of spiral turbine generators. It includes a mounting frame, with a first rotating column and a second rotating column respectively arranged on the top two sides of the mounting frame. One end of the first rotating column is connected to a generator. A fixed column is fitted onto the outer wall of the second rotating column. Four sets of springs are installed on one side of the fixed column, and a fixed rod is provided on one side of the fixed column. A knob is installed at one end of the fixed rod. In this utility model, before a new rotating rod is inserted into the first rotating column, the fixed column is pushed into the mounting frame. When the fixed column is released, the compressed springs on one side of the fixed column push the fixed column towards the rotating rod, allowing the rotating rod to insert into the second rotating column. Finally, the operator manually rotates the knob, causing the fixed rod to press and push the fixed column towards the rotating rod, ensuring that one end of the rotating rod is fully inserted into the fixed column. This method speeds up the disassembly and installation of the rotating rod.
