Document Type and Number:
WIPO Patent Application WO/2023/045767
Kind Code:
A1
Abstract:
A vibration frequency adjustment system, comprising a vibratable component (102), at least one counterweight (401, 402), at least one drive device (407, 408) and a controller (307). The vibratable component (102) is configured to be connected to a vibration source (101). The vibration source (101) has an operating frequency range, and the vibratable component (102) has a natural vibration frequency. At least one counterweight (401, 402) is configured to be movable along the vibratable component (102). At least one drive device (407, 408) is configured to enable the at least one counterweight (401, 402) to be maintained at or moved to a different weight position (421, 422, 423) on the vibratable component (102). The controller (307) is communicatively connected to the at least one drive device (407, 408). The vibration frequency adjustment system is used for a variable-frequency screw unit so as to reduce the vibration of an exhaust pipe.
