Problems solved by technology

[0002] At present, the structure of the passive pressure relief plate used in nuclear power units is relatively simple. When the indoor air or steam pressure exceeds the design pressure, the pressure relief plate cannot release the pressure of the indoor air or steam in time; The existing pressure relief plate cannot perform the function of draining water. At the same time, when a fire breaks out in the room, the current pressure relief plate cannot effectively block the spread of the fire source.

Abstract

The invention discloses a none-motile pressure relieving plate with a drainage function for a nuclear power unit. The pressure relieving plate comprises a frame, door planks, water releasing assemblies and fusible bolts; the door planks are provided with shearing bolt assemblies, the frame is provided with a bolt fixing seat, and shearing bolts in the shearing bolt assemblies are inserted into the bolt fixing seat; the water releasing assemblies are arranged on the inner side faces of the door planks, and each water releasing assembly comprises a blade shaft, a floating ball, a floating ball rod and a transmission gear set; and the two ends of the blade shafts are in transmission connection with the two sides of water releasing frames, the blade shafts are provided with blades, the planks are provided with water releasing channels corresponding to the blades, the floating balls are connected with the floating ball rods, the floating ball rods are furthermore in transmission connection with the blade shafts through transmission gear sets, the floating balls move up and down to drive the floating ball rods to poke the transmission gear sets to rotate the blade shafts, the blade shafts are rotated to make the blades open or close the water releasing channels on the door planks, and the water releasing frames are provided with the fusible bolts. The pressure relieving plate has the pressure relieving function and also has the water releasing and fire prevention functions.

Description

technical field [0001] The invention relates to a pressure relief plate for a nuclear power unit, in particular to a passive pressure relief plate with drainage function for a nuclear power unit, belonging to the technical field of nuclear power equipment. Background technique [0002] At present, the structure of the passive pressure relief plate used in nuclear power units is relatively simple. When the indoor air or steam pressure exceeds the design pressure, the pressure relief plate cannot release the pressure of the indoor air or steam in time; The existing pressure relief plate cannot perform the function of draining water. At the same time, when a fire breaks out in the room, the current pressure relief plate cannot effectively block the spread of the fire source. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the present invention provides a passive pressure relief plate with drainage function for nuclear power units, so th...
