AI Technical Summary

Technical Problem

Existing razor wire is difficult to extend and retract after deployment, occupies a large area, is inconvenient to operate manually, and poses a risk of injury to personnel, making it unsuitable for the application needs of nuclear power plants.

Method used

By combining the barbed wire with the gantry unit of the telescopic gate through the support components, the barbed wire can be flexibly extended and retracted. The combination of support components, fixing components and reset elastic components ensures that the barbed wire moves synchronously with the gantry unit, reducing the footprint and improving the ease of operation.

Benefits of technology

It enables flexible opening and closing of barbed wire, reduces the footprint, avoids personnel injuries, and improves deterrence and denial capabilities, making it suitable for auxiliary entrances and exits of nuclear power plants.

Abstract

The application provides a retractable gillnet access control device, and relates to the technical field of nuclear power plant security and protection equipment, comprising a retractable door and at least one gillnet, wherein the retractable door comprises a plurality of door frame units; each door frame unit is provided with at least one set of support assembly, the support assembly comprises a support piece, at least one fixing piece and a reset elastic piece, the support piece is movably connected to the door frame unit, the fixing piece is fixedly arranged on the support piece, the reset elastic piece is elastically connected between the support piece and the door frame unit, and the gillnet is connected to the fixing piece. The application has the beneficial effects that the gillnet and the door frame unit of the retractable door are connected together through the support assembly, so that the gillnet can be synchronously retracted and opened with the door frame unit, the floor area is reduced, the operation is facilitated, and the personnel injury is avoided. In addition, the movably connected support piece enables the gillnet to move and deform with the support piece when subjected to external force, so that the gillnet loses the function of serving as a climbing fulcrum, the deterrent and rejection effects are better, and the safety is higher.
