Utility model content
The purpose of this utility model is to provide a kind of noise detection device, to solve propose in above-mentioned background technology one
As noise monitor can not be according to the problems such as orientation measurement noise decibel.
For achieving the above object, this utility model provides following technical scheme:A kind of noise detection device, including decibel
Instrument, control panel and rotating seat, are fixed with grid in the decibel instrument, are provided with buzzer inside the grid, the grid
Right side is provided with controller, is connected with acoustic pressure detector on the right side of the controller, is provided with driving electricity on the right side of the control panel
Machine, is provided with transmission belt below the motor, is connected with rotating shaft on the right side of the transmission belt, and the rotating shaft is by the transmission
Band is connected with the motor, is fixed with swivel bearing below the rotating shaft, is provided with movable pulley, institute below the rotating seat
State rotating seat inner right side and lithium battery is installed, on the right side of the lithium battery, be connected with charging socket, fixed below the movable pulley
There is moving track, below the moving track, be connected with base, below the base, be provided with support.
Preferably, the buzzer and the control panel are electrically connected with.
Preferably, the outer lateral extent base inner wall 1mm of the rotating seat.
Preferably, the moving track is shaped as annular on base.
Preferably, the swivel bearing is rotatable device, and the anglec of rotation is 0-360 °.
Compared with prior art, the beneficial effects of the utility model are:The noise detection device is provided with rotating shaft and movable pulley,
Seat rotation can be rotated when acoustic pressure detector detects surrounding environment noise level, enable the ring of 360 degree of decibel instrument
Around detection noise, and instant noise can be recorded by controller, be fixed with buzzer, can detect in acoustic pressure detector in grid
Chimes of doom is sent during to the maximum direction of noise decibel, is convenient for people to the noise level that all directions are contrasted in noisy environment,
And user can be facilitated to find out noise source, moving track is shaped as annular on base, reduces rotation with movable pulley mating reaction
The frictional force produced during seat rotation, and the apparatus structure is simple, acquisition cost is low, easy to maintenance.

Specific embodiment
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out
Clearly and completely describe, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole
Embodiment.Embodiment in based on this utility model, those of ordinary skill in the art are not under the premise of creative work is made
The every other embodiment for being obtained, belongs to the scope of this utility model protection.
Fig. 1 is referred to, this utility model provides a kind of technical scheme:A kind of noise detection device, including decibel instrument 1, control
Panel processed 6 and rotating seat 8, are fixed with grid 2 in decibel instrument 1, be provided with buzzer 3, buzzer 3 and chain of command inside grid 2
Plate 6 is electrically connected with, and is provided with controller 4 on the right side of grid 2, is connected with acoustic pressure detector 5, on the right side of control panel 6 on the right side of controller 4
Motor 7 is installed, below motor 7, is provided with transmission belt 11, on the right side of transmission belt 11, be connected with rotating shaft 16, rotating shaft 16 is led to
Cross transmission belt 11 to be connected with motor 7, below rotating shaft 16, be fixed with swivel bearing 17, swivel bearing 17 is rotatable device,
And the anglec of rotation is 0-360 °, movable pulley 14,8 outer lateral extent base of rotating seat, 9 inwall 1mm, rotation below rotating seat 8, is provided with
8 inner right sides of seat are provided with lithium battery 12, be connected with charging socket 13, be fixed with movement below movable pulley 14 on the right side of lithium battery 12
Track 15, moving track 15 are shaped as annular on base 9, are connected with base 9 below moving track 15, arrange below base 9
There is support 10.
Operation principle:When using the noise detection device, first power supply is connected with charging socket 13, by lithium battery 12
Fully charged, the device is moved to place to be detected then, operational control panel 6 is started working, and acoustic pressure detector 5 is by surrounding
Sound is transferred to be converted into data signal in controller 4 and shows that, on control panel 6, now motor 7 is started working, driving
Motor 7 drives rotating shaft 16 to start to rotate on swivel bearing 17 by transmission belt 11, so that rotating seat 8 drives movable pulley 14 to exist
Circular mobile on moving track 15, acoustic pressure detector 5 will continue detection surrounding noise decibel, when certain angle noise decibel is higher than
Before during decibel data maximums, buzzer 3 will send sound by grid 2, can detect that environment is made an uproar by above step
The maximum direction of cent shellfish, here it is the operation principle of the noise detection device.
