Constructional engineering sound insulation device with multiple protection structures

Abstract

The invention provides a constructional engineering sound insulation device with multiple protection structures. The device comprises a noise reduction moving frame, universal brake wheels, U-shaped push rods, a fixed support hole, an adjustable noise reduction seat structure, an adsorbable noise reduction cover structure, a protective dustproof noise reduction box structure, a rotatable fixed warning seat structure, a protection block, a shielding cover, a fixed rod, a positioning nut, a locking nut, a suction fan, a connecting rod and a fixed nut, wherein the universal brake wheels are connected to the four corners of the lower end of the noise reduction moving frame through bolts respectively. According to the constructional engineering sound insulation device, through arrangement of anoise reduction adsorption box, a second fixing pipe, an adsorption cover, a corrugated hose, a connecting conveying pipe, the noise reduction moving frame and the suction fan, the suction force generated when the suction fan works in the working process is favorable for sucking away air around equipment through cooperation of the noise reduction adsorption box, the second fixing pipe, the adsorption cover, the corrugated hose and the connecting conveying pipe, noise is prevented from being spread through air to pollute the working environment, and meanwhile the equipment can be cooled conveniently.

Description

technical field [0001] The invention belongs to the technical field of sound insulation equipment, and particularly relates to a construction engineering sound insulation device with multiple protective structures. Background technique [0002] The harm of noise to the human body is systemic. It can cause changes in the auditory system and also affect the non-auditory system. The early effects of these effects are mainly physiological changes. Long-term exposure to relatively strong noise can cause pathological changes. In addition, noise in the workplace can also interfere with language communication, affect work efficiency, and even cause accidents. Construction in construction is one of the sources of noise. There are many equipment used on construction sites, and the equipment is noisy during operation. bigger. [0003] However, the existing sound insulation equipment still has the inconvenience of sound transmission through the air during use, inconvenient for noise re...
