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

[0063] Working principle: In the turbine power generation device of the present application, the first rotating shaft of the turbine and the driving rotating shaft of the permanent magnet speed governor rotate synchronously, the second rotating shaft of the generator and the driven rotating shaft of the permanent magnet speed governor rotate synchronously, and the translation of the movable housing can be achieved through the first translation mechanism and the second translation mechanism, so as to adjust the air gap between the driving rotor and the driven rotor, thereby achieving speed regulation. Moreover, the permanent magnet speed governor of the present application also has a heat dissipation function. The heat dissipation fan can introduce air into the annular housing, and the heat dissipation air flow enters the annular housing, passes through the connection channel, passes through the space inside the movable housing, 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 exits from the first air outlet hole and the second air outlet hole, thereby achieving heat dissipation. And driven by the first motor, the first plug rod can block the first air outlet hole, and driven by the second motor, the second plug rod can block the second air outlet hole, so as to ensure the sealing performance when the movable housing cooperates with the first and second housings when needed.

[0064] And when the device is operating properly, theoretically, the axes of the rotating shaft and the driven rotating shaft are collinear, and the spatial position of the cooperation between the first enclosing housing and the first slot will not change, and the spatial position of the cooperation between the first plug rod and the first outer ventilation hole will not change. Therefore, the measured values of the first pressure sensor and the second pressure sensor will not change. If the measured value of the first pressure sensor or the measured value of the second pressure sensor changes abnormally, it indicates that the cooperation between the movable housing and the first and second housings has changed abnormally, indicating that the axis position between the driving rotating shaft and the driven rotating shaft may have shifted, thereby reminding the maintainer to perform maintenance in a timely manner.

[0065] Although the present invention has been illustrated and described with respect to the preferred embodiments, those skilled in the art should understand that various changes and modifications can be made to the present invention as long as they do not exceed the scope defined by the claims of the present invention.
