Benefits of technology

This patented technology allows an automatic mechanism called Self Locked Lifeline® to securely hold up both the cover on top when it's closed with one side while also allowing easy access during opening. It provides better security against radiation exposure than existing methods like caskets used alone.

Problems solved by technology

This technical problem addressed in this patented text relating to radiation exposure from household sources such as radon gas production facilities or medical treatment centers involves finding ways to safely dispose of these wastes without causing harmful effects that could affect their long term health risks.

Abstract

The invention relates to a bucket cover self-locking device for a radioactive waste storage bucket. The bucket cover self-locking device is arranged on a bucket cover sealing device. The bucket coversealing device comprises a bucket cover rotating disk and a telescopic rod; a rotating shaft is arranged in the center of the bucket cover rotating disk; the bucket cover rotating disk is driven by the rotating shaft to rotate and drives the telescopic rod to move at the same time, and the end of the telescopic rod enters or is separated from an arc-shaped groove of a bucket cover flange fixedly connected with a bucket body; the rotating shaft comprises a shaft sleeve and a shaft core; a shaft core reset spring is arranged between the shaft sleeve and the shaft core; and the shaft core can move downwards in the shaft sleeve and compress the shaft core reset spring under the downwards pressing effect and can be reset upwards by the aid of the shaft core reset spring after the downwards pressing effect is relieved. The bucket cover self-locking device comprises a vertically-upward hinge pin connected with the shaft core of the rotating shaft; and hinge pin holes corresponding to different stations of the hinge pin are formed in the bottom of a bucket cover support. By the aid of the bucket cover self-locking device, the bucket cover rotating disk can be locked in different sealing oropening stations of a bucket cover, so that the equipment stability in the cover sealing or opening state is guaranteed, and related operations are safer and more reliable.
