Inertia force counteracting and self-stabilizing device for small offshore nuclear power reactor

Abstract

The invention discloses an inertia force counteracting and self-stabilizing device for a small offshore nuclear power reactor, comprising a spherical base. The top of the inner wall of the spherical base is connected with a spherical buffer block in a sliding fit manner; a horizontal fixed ring is fixedly mounted in the middle of the inner wall of the spherical base in the circumferential direction, and the middle of the spherical base transversely penetrates in the horizontal direction and is rotatably connected with a first rotating shaft in the circumferential direction; the middle of the first rotating shaft longitudinally penetrates in the horizontal direction and is rotatably connected with a second rotating shaft in the circumferential direction; the middle of the second rotating shaft penetrates vertically and is connected with a buffer lever in a sliding fit manner; the top of a buffer lever is coaxially and fixedly provided with a back shore column body, and the bottom of the buffer lever is coaxially and fixedly connected with a nuclear reactor power chamber; and the bottom of the nuclear reactor power chamber slides and is matched and supported on the arc-shaped surface of the bottom of the inner wall of the spherical base. According to the horizontal inertia force buffer device, radial inertia force is counteracted by utilizing angle deviation, and the resultant force direction of the horizontal inertia force and gravity is the same as the radial direction of the inner wall of a spherical tank, so that the phenomena of liquid shaking in a reactor and collision and extrusion between components are eliminated or weakened.

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...
