Problems solved by technology

[0005] In this case, the control system of the loading and unloading machine loses power and cannot be operated, controlled and displayed. If the loading and unloading process is in progress at this time, the operator needs to manually put the fuel assembly in a safe position through the on-site hand wheel. The location needs to be determined Read the value of the encoder, the monitoring of the friction force during the operation needs to read the value of the weight sensor

Abstract

The invention belongs to the technical field of loading and unloading of nuclear power units, and particularly relates to an emergency measuring device for a loading and unloading machine. The emergency measuring device comprises a storage battery power module, a weight signal conversion module, a weight display module, an encoder conversion module, a position display module and a terminal switching module, wherein the storage battery power module provides power for the weight signal conversion module, the weight display module, the encoder conversion module and the position display module; the weight signal conversion module transmits signals to the weight display module and the terminal switching module; and the encoder conversion module transmits signals to the position display module and the terminal switching module. The emergency measuring device has the characteristics of convenience in application and modularization, and satisfies the requirements of locating the position of afuel lattice and monitoring the frictional force borne by a fuel assembly under the condition of a power failure of a whole plant.

Description

technical field [0001] The invention belongs to the technical field of nuclear power assembly and unloading, and in particular relates to an emergency measuring device for a loading and unloading machine. Background technique [0002] The WWER nuclear power unit uses a loading and unloading machine to load and unload fuel assemblies. [0003] Under normal working conditions, the control system of the loading and unloading machine automatically determines the position of the fuel assembly grid by measuring the position with the absolute encoder; it uses the weight sensor to measure the friction force on the fuel assembly during the loading and unloading process, so as to avoid the impermissible friction force from causing fuel If the component is damaged, the control system automatically completes positioning, loading and unloading operations and weight protection. [0004] Loading and unloading operations are directly related to the safety of fuel assemblies, so not only no...
