High-performance air pressure shielding gate

Abstract

A high-performance air pressure shielding door is characterized by comprising a door frame (1) and a door leaf (2), wherein air pressure shielding components are arranged between the door frame (1) and the door leaf (2) and comprise a conductive reed (4), a flexible sealing board (5), a power transmission component (6), a micro cylinder (7) and a conductive frame (9). The high-performance air pressure shielding door guarantees the wide-band shielding effectiveness and is wide in application range; only one shielding door structure can cover a full band of the electromagnetic shielding field and meets design requirements of various shielding doors; not only are requirements of large shielding doors for an electric power test met, but also requirements of national military standards and shielding doors for anechoic chambers are met simultaneously; the high-performance air pressure shielding door adopts horizontal moving and lifting types, is power-driven or manually-operated, adopts frequency conversion and stepless speed regulation, and can perform sudden stop; a safe anti-clamping device is arranged; the electric interlocking is realized; and the high-performance air pressure shielding door is operated through a touch screen, thereby being convenient and visual to operate.

Description

technical field [0001] The invention relates to the field of electromagnetic shielding, in particular to a high-performance air pressure shielding door, in particular to a high-performance air pressure shielding door which solves the problem of shielding movable gaps in electromagnetic shielding rooms. Background technique [0002] Existing airtight screen doors have the following defects [0003] 1. The airbag is a key component of the door. It is difficult to ensure the consistency of the size of the uniform wall thickness, especially the poor consistency of the four corners of the door frame. , resulting in inconsistent contact pressure of the conductive reed, which greatly affects the shielding performance.

AI Technical Summary

Problems solved by technology

[0003] 1. The airbag is a key component of the door. It is difficult to ensure the consistency of the size of the uniform wall thickness, especially the poor consistency of the four corners of the door frame. It is difficult to make it on a plane, and it is easy to produce uneven height , resulting in inconsistent contact pressure of the conductive reed, which greatly affects the shielding performance

[0004] 2. The airbag has aging problems. After aging, it loses its elasticity and is easy to break, and its service life is greatly restricted.

[0005] 3. The gas capacity of the airbag is large, the inflation and deflation time is as long as several minutes, and the operation efficiency is low

[0006] 4. Due to the large air capacity of the air bag, the air pump needs to be selected with a large capacity, which brings serious problems of power consumption and noise pollution

[0007] 5. It is inconvenient to replace and maintain. It is necessary to take down the entire airbag, which is labor-intensive and increases maintenance costs.

[0008] 6. The inflated airbag has a strong force on the section steel, so it is necessary to use a large-scale section steel, which not only increases the weight, but also increases the cost

Therefore, for places with high performance requirements, two or more airbags must be designed, which makes the structure complicated, the cost increased, and the maintenance and replacement are more inconvenient
