Description
Technical field：
The present invention relates to electrical or mechanical apparatus field, relates generally to a kind of sound level test measurement device.
Background technology：
, it is necessary to which carrying out 360 degree of compartments around the equipment measures more spot noise figures during electrical or mechanical device measuring noise
Calculated, measurement point requirement is in same level, and apart from equipment reference emission identity distance from need to be consistent.Due to large-scale electricity
With power or the difference of function, its height and girth are different for gas and mechanical equipment, and measurement point quantity is from several to several
Ten are differed, and each measurement point needs to be maintained at same level and extremely difficult from identical apart from equipment reference emission identity distance,
It is time-consuming and laborious, it is impossible to meet requirement and manually measurement order of accuarcy is low one by one.For this problem, surveyed using sound level
Measuring device is tried, noise measuring equipment is fixed on device, technical staff calculates measurement height and away from reference emission identity distance
From rear, noise measuring equipment probe positions are adjusted, corresponding device measurement standard draws contour line, carries out surveying by contour line by a people
Amount.For electrical equipment noise testing, personnel need to operate when electrical equipment works, which uses insulation material
Matter, and metalwork is equipped with good earthed system, and the safety for making personnel has been grasped so as to ensure.
The content of the invention：
The defects of the object of the invention is exactly to make up prior art, there is provided a kind of sound level test measurement device, solution is never
With the measuring point stability during height and the electric of volume, mechanical equipment noise testing.
The present invention is achieved by the following technical solutions：
A kind of sound level test measurement device, includes base, and the lower end of the base is provided with universal wheel, its feature exists
In：The screw placed vertically is provided with the base, guide bracket is combined with the screw, the guide bracket, which is equipped with, to be used to fix
The fixation kit of tester, the side of the screw are equipped with guide rod, graduation mark, the side of the guide bracket are distributed with the guide rod
Equipped with the pilot hole coordinated is oriented to guide rod, the screw is driven by the motor of its bottom.
One end of the base is provided with the push-pull rod with push and pull bar.
The base is Dual-layer body structure, its upper strata disk body is rotatably installed on lower floor's disk body, the screw,
Guide rod is installed on the disk body of upper strata, and location hole is distributed with the upper strata disk body, positioning and locking is provided with the location hole
Bolt.
The fixation kit includes fixed seat, and the fixed seat is fixedly mounted on guide bracket, is set in the fixed seat
The card slot of steady noise tester is useful for, the card slot side is equipped with stent, and the stent, which is equipped with, is used for steady noise survey
Try the fixed component of instrument probe.
Insulating materials is coated with the fixed seat, and the front end of fixed seat is connected with copper ground wire.
The motor is installed on base, and the output terminal of the motor is provided with driving gear, the driving gear with
The driven gear engaged transmission installed on screw bottom.
Its principle is：By the structure of double-deck base, on the one hand play the role of support base, on the other hand can basis
Need to rotate it, ensure the probe face noise source of tester so that measurement accuracy higher, by fixation kit
Card slot in fixed seat clamps noise-measuring instrument, fixes probe by the fixed component on one side stand of card slot, ensures measuring instrument
Stability, the adjusting in whole process drives screw to rotate by motor, so as to drive guide bracket to be moved to corresponding position, its
It is easy to adjust quick, it is time saving and energy saving, meet the requirement quick and precisely positioned.
It is an advantage of the invention that：
The present invention is reasonable in design, by simple and convenient operation, on the one hand improves the accurate of noise of equipment measurement
Property, the work efficiency of tester is on the other hand improved, furthermore the personnel eliminated during electrical equipment noise testing touch
Electric security risk.
