Abstract

The invention discloses traction type monitoring equipment, which comprises a detector, a sleeve and a traction device, and is characterized in that two ends of the sleeve are respectively arranged on a wall body of a high-dose room in a penetrating manner and are communicated with the outside of the high-dose room, and other parts of the sleeve are arranged in the high-dose room; the detector is arranged in the sleeve, is located in the high-dose room and is used for detecting the radiation level in the high-dose room; the traction device is connected with the detector through a traction rope, is arranged outside the high-dose room and is used for pulling the detector to move in the sleeve, so that the detector reaches a preset detection position in the sleeve. The invention further discloses a nuclear facility. The monitoring equipment is convenient to install and overhaul, and the irradiation risk is small.

Description

technical field [0001] The invention belongs to the field of nuclear technology, and in particular relates to a traction monitoring device and a nuclear facility. Background technique [0002] Generally, there are some rooms in nuclear facilities with high radiation levels. This part of the rooms with high doses of radiation is equipped with a large number of process equipment, and there may be radiation critical risks. The radiation levels in the rooms need to be monitored. In the past, the monitoring of the radiation level of such a room was generally completed by the radiation detection instrument arranged in the room. However, due to the high background radiation level in the room, it was inconvenient for personnel to enter and leave the room, and some process equipment It is arranged extending downward from the floor of the room, which is difficult to install and maintain, and the risk of irradiation is high. SUMMARY OF THE INVENTION [0003] The technical problem to...
