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.

The present invention relates to a small hydroelectric power generation system utilizing water flow, wherein the system comprises: a pair of helical turbines (100) having a plurality of helical rotating blades that rotate in opposite directions to enable stable rotation even with resistance and lift caused by water currents and turbulent currents; a support frame (200) that stably supports the pair of helical turbines (100) underwater and can be fixedly mounted with one or more of them; a pair of guides (300) fixedly mounted on the support frame (200) that filter out the attachment of sludge flowing along currents or water flow, divide the fluid flow to allow it to flow into and out of the pair of helical turbines (100), and simultaneously increase rotational inertia to help the stable rotation of the turbines; and a gearbox (400) that matches the high torque of the pair of helical turbines (100) with the high rotational speed of the generator. By implementing a small hydroelectric power generation system using water flow characterized by including a power generation module (500) having a control means (510) that produces and controls alternating current (AC) electricity by the continuous and stable rotation of the above pair of helical turbines (100); and an air-floating body (600) that floats the power generation system to the upper part of the floating body when installing the power generation system underwater or during repair and maintenance, it has the effect of high energy conversion efficiency utilizing both drag force from the water current and lift force from the vortex, and stable power generation and repair and maintenance are possible even in turbulent and rapid currents.
