Description

Technical Field

[0001] The present invention relates to the technical field of turbine generators, and more specifically, to a turbine generator device based on permanent magnet speed regulation. Background Art

[0002] In the process of industrial production, there is often a large amount of excess pressure and excess energy that is not effectively utilized. Improving the energy recovery and utilization system will help improve the comprehensive utilization efficiency of energy and promote sustainable economic development. High-speed turbine generators can convert the excess pressure and waste heat of working fluids into high-quality electrical energy, which can be directly used in production or connected to the power grid. Usually, the turbine is directly driven by high-temperature or high-pressure working fluids, and the output power of the turbine is transmitted to the generator through the power shaft and reduction gearbox for power generation.

[0003] In the actual application of existing turbine generators, the gear reducer will produce a certain amount of energy loss due to the friction between the gears during the power transmission process, which affects its transmission efficiency. And sometimes there is a problem of poor heat dissipation during the transmission process. In addition, the axis alignment of the driving shaft and the driven shaft is also a key factor affecting the stability and efficiency of the system. The existing detection methods for axis alignment often have the problem of not being timely enough. This is mainly because traditional detection methods often rely on manual experience and simple measurement tools, which are difficult to achieve real-time monitoring. Summary of the invention

[0052] Working principle: In the turbine power generation device of the present application, the first rotating shaft of the turbine and the active rotating shaft of the permanent magnetic speed regulator rotate synchronously, the second rotating shaft of the generator and the driven rotating shaft of the permanent magnetic speed regulator rotate synchronously, and the first translation mechanism and the second translation mechanism can realize the translation of the movable shell, so as to adjust the air gap between the active rotor and the driven rotor, so as to realize speed regulation. In addition, the permanent magnetic speed regulator of the present application also has a heat dissipation function, and the heat dissipation fan can take in air into the annular shell, and the heat dissipation airflow enters the annular shell, passes through the connecting channel, passes through the space inside the movable shell, passes through the first inner ventilation hole and the second inner ventilation hole, passes through the first slot and the second slot, passes through the first outer ventilation hole and the second outer ventilation hole, and discharges air from the first air outlet and the second air outlet, so as to realize heat dissipation.
