Title:
SOURCE TURN-OFF DEVICE AND TREATMENT HEAD
Document Type and Number:
WIPO Patent Application WO/2022/121926
Kind Code:
A1
Abstract:
Provided in the embodiments of the present application are a source turn-off device and a treatment head. The source turn-off device comprises: a transmission assembly and an energy storage assembly, wherein the transmission assembly is fixedly connected to a source carrier, and the transmission assembly has the same axis of rotation as the source carrier; one end of the energy storage assembly is connected to the transmission assembly; when the source carrier is at a source turn-off position, the energy storage assembly is in a natural state; when the source carrier rotates from the source turn-off position to a source turn-on position, the transmission assembly drives the energy storage assembly to store energy; and when a source is turned off, the energy storage assembly releases energy, and the source carrier rotates from the source turn-on position to the source turn-off position. In the embodiments of the present application, when an apparatus has a power supply system failure, for example, when neither a mains supply nor a UPS can supply power to a control system to automatically turn off a source, the energy storage assembly releases the stored energy to drive the transmission assembly and the source carrier to rotate and thus enable the source carrier to automatically return to the source turn-off position so as to shorten the radiation exposure time.
