Problems solved by technology

The application of the wing gate has significantly improved the efficiency of personnel access inspection, but during the operation of the wing gate, opening and closing will generate noise. The main source of noise is the wing gate movement. The wing gate movement includes motors, gear transmission, and transmission shaft rotation. Frequent opening and closing is noisier and lasts longer

Abstract

The invention discloses a noise reduction shell for a wing gate. The noise reduction shell comprises a shell body; the noise reduction device is arranged at the bottom of the shell body, and the noise reduction device comprises a pair of buffer strips which are oppositely laid at the bottom of the shell body; the supporting plate is fixed above the buffer strip through a plurality of supporting columns and is used for fixing a base of a wing gate machine core; the sound absorption layer I is laid at the bottom of the shell body and located between the buffer strips, and a gap is formed between the sound absorption layer I and the buffer strips; the sound absorption layer II is laid at the bottom of the supporting plate and located above the sound absorption layer I; the springs are arranged at intervals, and the upper ends and the lower ends of the springs are fixed to the sound absorption layer I and the sound absorption layer II respectively. The wing gate has the beneficial effects that the operation noise of the wing gate is remarkably reduced, and outward transmission of noise generated by a wing gate machine core is reduced.

Description

technical field [0001] The invention relates to the field of wing gate passage devices. More specifically, the present invention relates to a noise reduction housing for a flap gate. Background technique [0002] Wing gates are widely used, such as scenic spots, venues, parks and other places, as well as public places such as airports, railway stations and bus stations. The application of the wing gate has significantly improved the efficiency of personnel access inspection, but during the operation of the wing gate, opening and closing will generate noise. The main source of noise is the wing gate movement. The wing gate movement includes motors, gear transmission, and transmission shaft rotation. Frequent opening and closing is noisier and lasts longer. Therefore, it is worth studying to design a housing that can reduce the above-mentioned noise. Contents of the invention [0003] It is an object of the present invention to solve at least the above-mentioned problems ...
