Problems solved by technology

[0002] It is well known that an effective measure to reduce noise is to shield the machine with a sound insulation cover. The noise of some pressurized equipment is extremely high during operation, up to 99-104dB, which seriously affects the on-site operation of the operator and the environment near the equipment. Traditional insulation The structure of the sound enclosure is single, it is not easy to disassemble and repair the equipment, and the ventilation and sound insulation of the sound insulation enclosure are contradictory, which always affects the development of the sound insulation enclosure. Therefore, it is urgent to provide a new technical solution to solve the above problems

Abstract

The invention discloses a sound insulation cover, comprising a cover body outside a sound source device. The cover is composed of a shell and a sound absorption layer connected to the inner wall of the shell, and the cover body is connected with the sound source device by a vibration isolator; a through hole is opened in the cover body; and a muffling structure, namely a muffling pipe, is mounted in the through hole, and a muffling material is lined on the inner wall of the muffling pipe. The sound insulation cover is characterized in that a ventilation muffler is mounted on the top of the sound insulation cover, and a muffling heat-dissipation hole in a rectangular bent shape is formed in one side surface of the sound insulation cover. The sound insulation cover has the advantages of being capable of effectively reducing noises, and being easy to assemble and disassemble and high in practicality.

Description

technical field [0001] The invention relates to a sound insulation device, in particular to a sound insulation cover. Background technique [0002] It is well known that an effective measure to reduce noise is to shield the machine with a sound insulation cover. The noise of some pressurized equipment is extremely high during operation, up to 99-104dB, which seriously affects the on-site operation of the operator and the environment near the equipment. Traditional insulation The structure of the sound enclosure is single, it is not easy to disassemble and repair the equipment, and the ventilation and sound insulation of the sound insulation enclosure are contradictory, which always affects the development of the sound insulation enclosure. Therefore, it is urgent to provide a new technical solution to solve the above problems. Contents of the invention [0003] The object of the present invention is to provide a sound insulation cover that can effectively reduce noise, is ...
