Abstract: The present invention relates to a shielding chamber for an accelerator and a construction method therefor, and a method for testing an accelerator. The shielding chamber includes a top wall, a circumferential wall, and a side door. The circumferential wall together with the top wall encloses an inner space, the circumferential wall is configured to have a lateral opening, and the lateral opening communicates with the inner space for the accelerator to enter the inner space through the lateral opening. The side door has a side door body, the side door body is configured to block the lateral opening of the circumferential wall and is movable in a first direction, and the first direction is perpendicular to a plane on which the lateral opening is located.

Abstract: Disclosed are a method and device for implementing a microwave device trusteeship. The method includes: a plurality of all-outdoor units (AOUs) are configured into a trusteeship mode; res the AOUs already configured into the trusteeship mode are respectively connected to the ports of the service units of an IP device; by accessing the IP device by the AOUs configured into a trusteeship mode, the connected AOUs are configured at the corresponding ports of the service unit of the IP device, and the virtual slot numbers of the connected AOUs are generated; and the IP device selects at least two AOUs from the plurality of AOUs already configured into a trusteeship mode to form a protection group, and sets a transmission unit number for each selected corresponding AOU, so as to virtually set each of the selected AOUs as a transmission unit of the IP device.

Abstract: An oil discharging system for a main shaft bearing of a wind turbine generator, includes: a main shaft bearing, a bearing seal, a bearing end cover, a waste oil through hole, at least one thumb wheel; the bearing seal is sleeved to an end of the main shaft bearing, the bearing end cover is engaged with the bearing seal to encircle the outside of the bearing seal; the waste oil through hole is provided on the bearing end cover; the at least one thumb wheel is provided on the bearing seal, enables the waste oil been discharged from the waste oil through hole after the thumb wheel acts upon. Since the thumb wheel rotates with the main shaft bearing, so that the waste oil discharge from the waste oil through hole effectively, thus pollutions to the wind turbine generator and surroundings thereof are reduced.
