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.

An inlet system comprises a split-spiral turbocharger, including a turbine housing, a first spiral, a second spiral, a turbine housing outlet, and a wall separating the first spiral from the second spiral. The wall has a first wall surface. The inlet system further includes a blade ring. The blade ring includes a blade partition that further separates the first spiral from the second spiral. The blade partition has a blade parting surface that faces the first wall surface. The blade ring includes several blades coupled to the blade partition. The first wall surface and the blade parting surface define a confinement path between each other. At least one segment of the confinement path is non-parallel, so that exhaust gas leakage from the first or second spiral to the other—the first or the second—is reduced.

This invention provides a small underwear washing machine, belonging to the technical field of small washing machines. It includes a main housing and a water supply mechanism, comprising a water tank located inside the main housing for storing and supplying water for cleaning clothes; and a cleaning mechanism, including a drive motor located at the bottom of the main housing and a cleaning wheel connected to the output shaft of the drive motor. During operation, the invention utilizes a spiral turbine-like design with large protrusions and ribs to generate rotating vortices when the cleaning wheel rotates. This not only drives the clothes to rotate and tumble, increasing the contact stress between the clothes and water, but also improves the overall cleaning effect regardless of the size of the clothes. Furthermore, the ribs provide flexible protection during washing, preventing clothes from twisting together and improving the cleaning effect. They also prevent excessive rotational resistance caused by clumped clothes, which could increase the resistance of the drive motor and burn out the internal coils.

2.1 Conventional drag rotors have convex or concave rotor blades. While the concave turbine parts generate torques acting in the direction of rotation, the convex turbine parts generate torques opposing the rotation. Since the torque responsible for rotation is the difference between the two, the efficiency of such wind turbines is low. The minimum wind speed required for reliable turbine rotation also presents a problem. The new device is intended to generate electrical energy with greater efficiency, even at low wind speeds. 2.2 The device comprises a helical turbine (2) connected to a generator (1). An air guide (5) on the windward side accelerates incoming air masses and, thanks to its rectangular shape, directs them to those blades (3) of the turbine (2) that move with the wind. This baffle prevents convex blades from being impacted by the incoming air. Additionally, outer baffle elements (8) are connected to their respective blades and exhibit a concave shape as they move with the wind direction. 2.3 Due to its vertical axis of rotation, the rotor can be used in small wind turbines for decentralized energy systems.
