Fully automatic hanging arc guide rail two-dimensional electromagnetic shielding door

Abstract

The invention discloses a fully-automatic suspension type two-dimensional electromagnetic shielding door wit arc-shaped guide rails, comprising a door frame (1), a door leaf (3) and a control system (15), wherein the door frame (1) is fixedly arranged on the side wall of a shielding room, and the periphery of the door frame is in seamless welding with a shielding body steel plate; the door frame (1) is externally provided with a supporting framework (5); a suspending-displacement device (8) for suspending the door leaf is arranged on the supporting framework (5); the door leaf (3) is arranged at the lower part of the suspending-displacement device (8); the suspending-displacement device (8) is provided with a motor and a synchronizing device (9); and the suspending-displacement device (8) controls the motor and the synchronizing device (9) to drive the door leaf (3) to do vertical and translational two-dimensional movement at the lower part of the suspending-displacement device (8). The fully-automatic two-dimensional electromagnetic shielding door disclosed by the invention has the advantages that the design is novel and reasonable, the performance is excellent, the operation is simple, the maintenance is convenient, the whole-process operation of the shielding door is automatic, the influence of the inertia of the large suspension type shielding door on the operating stability is avoided, the quantity of motors of the shielding door is less, the structure is more reasonable and the control is more reliable; due to the adoption of a knife-groove meshing mode and a pneumatic locking mechanism, accurate alignment and stable and reliable meshing of the door leaf and the door frame are ensured, the possible deformation of the door leaf and the door frame in use is furthest reduced, and high shielding effectiveness is ensured.

Description

technical field [0001] The invention relates to the field of engineering electromagnetic protection technology (electromagnetic shielding technology), and mainly relates to a large-scale fully automatic two-dimensional electromagnetic shielding door with a suspended curved guide rail. Background technique [0002] With the development of electronic technology, various military and civilian electronic equipment and systems have been widely used, and various electromagnetic waves radiated from this criss-cross, continuously interleave, and densely overlap in a certain time domain, air domain, and frequency domain. The complex electromagnetic environment has caused serious electromagnetic pollution. These complex electromagnetic environments will not only cause interference or damage to electronic equipment and systems, but also bring harm to human health. What is more serious is the information security problem caused by electromagnetic weapon strikes, which may directly threa...

Problems solved by technology

This kind of door is generally only used for large screen doors with heavy weight (about 3 tons). Its size is determined according to needs, generally about 4m×4m, and the shielding efficiency is also required to be high, so it is difficult to design and manufacture.

The opening and closing method of this kind of door can only be realized by multi-dimensional movement, and in the previous design, multiple motors were used, which required high synchronization devices. The large-scale fully automatic screen door is more complicated in terms of structure composition, operation mode, operation speed and operation control, and has higher technical content. It is mainly used in large-sized electromagnetic shielding rooms such as microwave anechoic chambers.

In addition, the lower edge of the door frame of this structure is generally about 200mm higher than the ground, which brings inconvenience to large equipment entering and leaving the shielding room, and it is necessary to take targeted measures to solve it.

[0005] Due to the urgent need for fully automatic large screen doors and broad application prospects, and the large screen doors currently on the market are still difficult to meet the requirements of use, therefore, the development of fully automatic large screen doors with high performance, fast and stable opening and closing has become an engineering application problem to be solved
