Embodiment Construction

[0013] The implementation of the present invention mainly includes two parts of mechanical and electrical control. The mechanical part is mainly composed of sound insulation cover, sound insulation door, controllable low-noise centrifugal exhaust system, air inlet muffler with controllable air volume, etc.; the electrical part is mainly composed of control part and servo mechanism.

[0014] 1. Description of each device of the mechanical part of the invention:

[0015] Sound insulation cover: In consideration of reliability, sealing, service life and other aspects, this invention adopts polyurethane double-sided composite insulation board. Since there are grooves and hooks at the joints between the boards, and the thickness of the boards can be selected according to the sound insulation requirements, it is easy to install and disassemble, easy to maintain, and the sound insulation effect is good. In principle, noise can be completely eliminated if the sealing performance is h...

Abstract

The design of current domestic noise insulation hood is still of a pure mechanical structure, and once the noise insulation hood is manufactured, the sound insulation volume thereof is determined, but in fact, as the change of operation load and conditions, the noise energy radiated by a noise source also changes, therefore, the prior noise insulation hood is purely mechanical noise insulation and lacks function of intelligent and automatic control. The noise insulation hood with the sound insulation volume thereof being intelligently controlled is developed and investigated on account of the defect, and is specifically designed for large-scale noise source, such as large-scale gas compressors. The invention combines modern control theory, computer technology and noise control theory to invent a novel noise insulation hood with intelligently controlled sound insulation volume (for the arrangement diagraph of the specific device, see the abstract attached diagraph 1) which solves the above problems completely and can meet different user requirements. The characteristic of the invention lies in the automatic processing of the two problems of noise source heat dissipation and the sound insulation volume of noise source in different frequency range (comprising high, low and intermediate frequencies), thus solving the problem of ventilation and heat dissipation of compressors, realizing comprehensive intelligent and automatic control of the sound insulation volume of sound insulation devices simultaneously, and having the advantages of humanization and intellectualization.

Description

technical field [0001] The sound insulation cover with intelligent control of the sound insulation is a brand new sound insulation device that can control the sound insulation. The invention controls the sound insulation of the sound insulation cover by using a computer (or PLC), an acoustic sensor and an actuator, and belongs to the scope of vibration and noise control. Background technique [0002] Most industrial equipment will produce serious noise pollution during use, such as large-scale gas compression equipment composed of motors, couplings, speed increasers, compressors, etc., the noise of which has been tested is as high as 100-120dB(A). It far exceeds the relevant national noise control standard of 85-95dB(A), which not only endangers the physical and mental health of operators, but also causes serious noise pollution to the surrounding environment. Therefore, reducing the noise of equipment is one of the key research topics in the field of noise control at home ...
