Underground nuclear power radiation immune type rescue platform

Abstract

Relating to the technical field of underground nuclear power stations, the invention discloses an underground nuclear power radiation immune type rescue platform. The rescue platform includes a console and an execution platform that are connected through a pneumatic pipe, the console comprises gas source equipment connected to the pneumatic pipe and an operation module controlling gas supply of the gas source equipment, the execution platform comprises an advancing module and a loading platform arranged on the advancing module, and the loading platform is provided with a pneumatic control module connected to the pneumatic pipe, a pneumoelectric conversion control module for receiving signal output of the pneumatic control module and a mechanical manipulator. The underground nuclear power radiation immune type rescue platform provided by the invention overcomes the influence of strong nuclear radiation from the design principle, increases the continuous action time, and improves the working efficiency.

Description

Technical field [0001] The invention relates to the technical field of underground nuclear power plants, in particular to an underground nuclear power radiation immune rescue platform. Background technique [0002] In a serious accident at a nuclear power plant, the core melt spouted out of the pressure vessel, and radioactive core fragments and corrosion products generated strong background nuclear radiation in the containment. At this time, the lethal radiation made the containment a forbidden zone for humans. Especially when a nuclear accident occurs in underground nuclear power, the surrounding rock mass becomes a new radiation source due to the deposition of radioactive particles. Under the same conditions, the radiation intensity of the cavern is much higher than that of the ground. At this time, due to the implementation of accident rescue, accident mitigation, etc., rescue devices must be sent to the safe area to investigate and evaluate the situation inside the containme...

AI Technical Summary

Problems solved by technology

Affected by high radiation, the robot was overwhelmed after working for about two hours. At this time, it only traveled about one meter in the containment, which seriously affected the accident rescue and evaluation

[0005] Chinese utility model patent application (public date: February 22, 2017, publication number: CN205964376U) discloses a nuclear radiation and radioactive accident emergency treatment trolley, which uses an electrical signal control module to control various actions of the trolley, in order to prevent nuclear radiation Affect the normal use of the rescue car control chip, usually a layer of radiation shielding material is added to the key control chip, but when the environmental radiation intensity is too high, in order to achieve the purpose of protection, the required radiation shielding material will increase sharply, seriously affecting the rescue car. usage of

In the Fukushima accident investigation, taking the typical radionuclide cesium 137 pollution as an example, if the radiation level is to be reduced from 650 sieverts per hour to an acceptable range, when the robot uses lead as a shield, the lead thickness will reach 20 centimeters, which is unacceptable both by design and by use
