Embodiment Construction
[0027] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.
[0028] It should be noted that when a component is referred to as being “fixed on” or “disposed on” another component, it may be directly on the other component or indirectly on the other component. When an element is referred to as being "connected to" another element, it can be directly or indirectly connected to the other element. The orientation or positional relationship indicated by the terms "upper", "lower", "left", "right", etc. are based on the orientation or positional relationship shown in the drawings, and are for convenience o...

The invention belongs to the technical field of nuclear power station radioactive decontamination, and provides a laser decontamination device for a nuclear power station. The laser decontamination device comprises a laser decontamination body, wherein the laser decontamination body is provided with a connector for connecting an optical cable, the laser decontamination body is also provided with a supporting plate, and the supporting plate is located below the connector. According to the laser decontamination device, the supporting plate located below the connector is arranged on the laser decontamination body, and when the connector is connected with the optical cable, the supporting plate supports the connecting part of the optical cable and the connector and supports the optical cable, so that bending and deformation caused by drooping of one end, connected with the laser decontamination device, of the optical cable due to gravity can be reduced, and optical fiber in the optical cable is not easy to damage; and due to the design of the supporting plate below the connector, when a worker holds the laser decontamination body by hand, the worker does not need to erect the optical cable on an arm to prevent the optical cable from being excessively bent or deformed, and the arm is prevented from being swollen and tired.
Description
technical field [0001] The application belongs to the technical field of radioactive decontamination of nuclear power plants, and more specifically relates to a laser decontamination device for nuclear power plants. Background technique [0002] During the operation of nuclear power plants, the corrosion products of materials and the primary circuit coolant are activated by neutrons to form radioactive substances that are transmitted, distributed, and deposited on the surfaces of pipes, valves, pumps and other components. As the service time of nuclear power plants increases, these radioactive substances accumulate Increasingly, the radiation field of the system is enhanced, and the radiation dose of the staff is increased. Therefore, regular or irregular radioactive decontamination is required to ensure the safe operation of the power station and reduce the collective radiation dose of operating personnel. [0003] Laser decontamination refers to the use of high-energy las...
