Abstract
(EN)
The present invention provides a device gate for a nuclear power plant, comprising a shell ring fixedly connected to a penetrating member of a safety housing. The device gate for the nuclear power plant further comprises: a gate end enclosure provided corresponding to an end surface of the shell ring and used for being sealedly connected to the shell ring; a hoisting lifting assembly provided above the gate end enclosure, movably connected to the gate end enclosure, and used for performing hoisting and resetting on the gate end enclosure; a high-position suspending assembly provided above the gate end enclosure and used for being detachably connected to the gate end enclosure when the gate end enclosure is hoisted to a specified position; and an anti-seismic limiting assembly partially provided on the safety housing, movably connected to the gate end enclosure, and used for performing limiting and anti-seismic processing on the gate end enclosure when the gate end enclosure is suspended on the high-position suspending assembly. The present invention ensures reliability and anti-seismic requirements of the device gate for the nuclear power plant.
