As described in Figure 7, it includes body 1 and the Pitot tube 3 being arranged on body 1 to existing air velocity duct measurement apparatus,
The measurement end of Pitot tube 3 is located inside body 1, and it can accurately measure the wind speed in body 1.
But after the air velocity duct measurement apparatus installs, Pitot tube 3 is an exposure to outside, used in everyday
During foreign object strike Pitot tube 3 occurs so that there is the phenomenon damaged in Pitot tube 3.
Utility model content
The purpose of this utility model is to provide a kind of air velocity duct measurement apparatus, and it can be played very to wind speed measurement mechanism
Good protective effect, prevents Pitot tube from being damaged by external force collision to a certain extent.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of air velocity duct measurement
Device, including body, guard box is provided with the body outer ring surface, wind speed measurement mechanism, institute are provided with the guard box
State and first through hole is provided with guard box, the second through hole communicated with first through hole is provided with the body outer ring surface, it is described
The test side of wind speed measurement mechanism is extend into body through first through hole, the second through hole.
By above-mentioned setting, when the ventilation in pipeline is measured, body is installed on pipeline, and due to wind speed
The test side of testing agency is extend into body, when have wind out of pipeline by when, its will necessarily pass through body in, at this moment
An air speed value can be detected accordingly by waiting wind speed measurement mechanism, be convenient for people to real time inspection；And because wind speed measurement mechanism makes
Inside guard box, therefore guard box can play a very good protection to wind speed measurement mechanism, to a certain extent
Effectively prevent wind speed measurement mechanism from occurring the phenomenon damaged due to external force collision.
Preferably, in addition to the display being arranged on protection box outer wall and the processor that is arranged in guard box, institute
State wind speed in wind speed measurement mechanism detection pipeline and export a wind speed measurement signal to the processor；
A wind speed, which is exported, after the processor reception wind speed measurement signal displays signal to the display；
The display receives the wind speed measurement signal and shown.
By above-mentioned setting, when wind speed measurement mechanism detects an air speed value, wind speed can be converted into one by it
Wind speed measurement signal is sent at processor, and processor can handle the wind speed measurement signal, and the wind speed measurement signal is changed
Showing that signal is sent to display into a wind speed, and after display receives the signal, the signal can be shown, so that
A wind speed measurement value is shown on display screen, such staff, can be very by the display screen on protection box outer wall
The convenient wind speed read in pipeline, it is not necessary to read after opening guard box, whole operation is simple and convenient；Moreover, work as
When external force collision guard box, guard box can protect wind speed measurement mechanism without damage, even and if display screen be knocked

And because installing plate is that pole is fixedly connected, therefore the contact area that can be effectively increased between guard box and pole, improve
The fixed effect of guard box, and need not be in order to improve the fixed effect of guard box, and pole is specially done to especially thick, drop
Low unnecessary material input.And when guard box is received towards the pressure of body, due between guard box and installing plate
Possess larger contact area, act on pressure to guard box so as to effectively reduce pole, can prevent to a certain extent
Only there is deformation phenomenon in guard box.
Preferably, lug is provided with the wind speed measurement mechanism, be provided with the lug, guard box and installing plate according to
The screwed hole of secondary connection, screw sequentially pass through the fixation that 3 screwed holes realize lug, guard box and installing plate.
By above-mentioned setting, when assembled conduit wind speed measuring device, make the spiral shell on lug, guard box and installing plate
Pit is in the state of alignment, and screw then is passed through into this 3 screw holes, realizes the fixation of wind speed measurement mechanism and guard box,
Fixation between any two need not be realized by multiple bolts, it is easy for installation.
Preferably, covering is upper elastic in the side wall of the first through hole, the second through hole, third through-hole and fourth hole
Layer.
Pass through above-mentioned setting, when wind speed measurement mechanism is extruded by external force and tilt phenomenon occurs, test side meeting
Contradicted with the side wall of through hole, and by covering rubber layer on first through hole, the second through hole, third through-hole and fourth hole, energy
When enough being contradicted in test side and above-mentioned through-hole side wall, certain protective role is played to test side, prevents from detecting to a certain extent
There is the phenomenon damaged in end.
Preferably, in the first through hole, the second through hole, third through-hole and fourth hole, at least set on a through-hole side wall
Neck is equipped with, the fixture block coordinated with neck is provided with the side wall of the elastic layer.
By above-mentioned setting, when rubber layer is covered, rubber layer is first extruded, rubber layer a certain degree of shape is occurred
Become, then rubber layer is extend into through hole, makes the projection face neck in rubber layer, then no longer forces in rubber layer, this
When rubber layer can recover deformation, now, the side wall of rubber layer and first through hole, the second through hole, third through-hole, fourth hole it is interior
Wall is bonded, and fixture block can be snapped onto in neck, and so as to realize effective fixation of rubber layer, whole installation process is very convenient.
In summary, the utility model has the advantages that：
