Mobile noise insulation house for people to observe vibration test equipment

Abstract

The invention provides a mobile noise insulation house for people to observe vibration test equipment. The mobile noise insulation house for people to observe vibration test equipment comprises four side walls, a ceiling portion and a base plate portion, wherein all the side walls, the ceiling portion and the base plate portion are made of composite noise insulation sheet materials, and can absorbthe noise in the full frequency range; a power socket, a fresh air system, and the like are also arranged in the noise insulation house; during the on-site using process of the mobile noise insulation house, the noise can be reduced by 50 db, so that the mobile noise insulation house has low demand for the application site; and by means of self-contained wheels of the mobile noise insulation house, the mobile noise insulation house is convenient to transport and move and can effectively reduce the noise. The mobile noise insulation house for people to observe vibration test equipment has theadvantages of being complete in the ventilation and air exchange system, having a self-contained temperature control system, being reasonable in design, being simple in structure, being easy to manufacture, being low in cost, being convenient to move, being environmentally friendly, having no pollution, being long in service life, being high in reliability, being high in practicality, and providing a safer and more comfortable feeling for the user.

Description

technical field [0001] The invention relates to the field of vibration test equipment, in particular to a mobile noise-isolation room for personnel to observe vibration test equipment. Background technique [0002] Vibration test equipment, also known as vibration exciter or vibration table, is a device that uses electric, electro-hydraulic, piezoelectric or other methods to obtain mechanical vibration. Its principle is to input an excitation signal into a coil placed in a magnetic field to drive The vibrating table connected to the coil simulates the vibration environment generated during the manufacturing, assembly, transportation and use of the product. [0003] In recent years, with the development of my country's industrialization, more and more large-scale equipment needs to be assessed by vibration tests, which has led to the development of domestic vibration equipment from small vibration tables with low thrust to large vibration tables with high thrust, so that vibr...

Problems solved by technology

[0005] It can be seen that the inventions and utility models of the mobile noise-isolation room in the prior art mainly use equipment placed inside the sound-proof room, and personnel observe from the outside. However, this observation method wastes the space resources of the noise-isolation room , this kind of noise-proof room needs to install a sound-proof room for each or several pieces of equipment, which occupies too much space resources, but instead allows the staff who need to operate to observe outside and cannot facilitate the control and management of the equipment; On the one hand, the observation angle of the noise isolation room in the prior art is single, and the observation of the equipment cannot be carried out in all directions, so that the noise isolation room needs to frequently change the position of the observation equipment; in addition, the noise isolation effect and heat preservation effect of the existing noise isolation room Not very good; the above factors have greatly limited the development of mobile noise isolation rooms
