Detailed Description

For further understanding of the present invention, embodiments of the present invention are described below with reference to examples, but it should be understood that these descriptions are only for the purpose of further illustrating the features and advantages of the present invention, and are not intended to limit the present invention.

The embodiment of the utility model discloses a remote transfer device of camera for high radiation district, a serial communication port, include: the device comprises a transfer trolley 1, a shielding and protecting sleeve 3 and a long rod support 2;

a shielding protective sleeve 3 is arranged on one side of the transfer trolley 1, and a peeping window 4 is arranged on the upper part of the transfer trolley 1;

the shielding protective sleeve 3 consists of a protective layer, a slot is formed in the protective layer, and the long rod support 2 penetrates through the slot and is fixed on a shaft of the transfer trolley 1;

the upper end of the shielding protective sleeve 3 is in lap joint with the lower end of the peeping window 4; the end part of the long rod support 2 extending out of the protective layer is provided with a lifting hook 5.

This transfer device is according to ionizing radiation protection three principles: the concept of time protection, distance protection and shielding protection is designed.

According to the utility model discloses, one side of transporting dolly 1 sets up shielding protection suit 3, 1 upper portion of transporting the dolly sets up peep hole 4, peep hole 4 is the modularization peep hole, and preferred lead glass is as main part material.

The shielding protection suit 3 comprises the inoxidizing coating, shielding protection suit 3 convenient to detach can shield a large amount of radiation. The protective layer adopts lead skin as a main material;
