A self-stabilizing device for counteracting inertial force of a small offshore nuclear power reactor

Abstract

A self-stabilizing device for counteracting the inertial force of a small offshore nuclear power reactor, comprising a spherical base, the top of the inner wall of the spherical base slides and fits with a spherical buffer block, the middle part of the inner wall of the spherical base is circumferentially fixed with a horizontal fixing ring and the spherical base The middle part of the first rotating shaft penetrates horizontally and horizontally and rotates to connect with the first rotating shaft; the middle part of the first rotating shaft penetrates horizontally and longitudinally and rotates to connect with the second rotating shaft; The top of the buffer lever is coaxially fixed to the top support column, and the bottom of the buffer lever is coaxially fixed to the nuclear reactor power chamber; the bottom of the nuclear reactor power chamber slides and is matched and supported on the arc surface at the bottom of the inner wall of the spherical base. The horizontal inertial force buffer device uses angular offset to offset the radial inertial force, and the direction of the resultant force of the horizontal inertial force and gravity is the same as the radial direction of the inner wall of the spherical tank, thereby eliminating or weakening the liquid sloshing inside the reactor and between components The phenomenon of collision extrusion.

Description

technical field [0001] The invention relates to the technical field of nuclear engineering, in particular to an inertial force offset self-stabilizing device for a small marine nuclear power reactor. Background technique [0002] At present, domestic and foreign nuclear engineering research fields are intensifying efforts to develop miniaturized, modularized, and low-power portable nuclear power devices. Compared with traditional large-scale commercial nuclear power plants, this kind of nuclear power plant has great advantages in mobility, and can be used in application scenarios such as power supply for offshore floating platform operations, rapid wartime power deployment, and disaster relief power supply. One of the engineering problems that needs to be focused on and urgently resolved in the research of nuclear power platforms applied in marine environments is how to ensure the safe operation of nuclear reactor systems under the working conditions of offshore nuclear powe...

Problems solved by technology

[0005] After analysis, the ship-borne self-stabilizing platform in the above-mentioned published patent is quite different from the present application in terms of structure, function and inertial force offset principle, so it does not affect the novelty of the present application
