It includes framed bent main body and signal receiver, passes through main line between framed bent main body and signal receiver
Cable connects, and framed bent main body includes framed bent base, is provided with body, on framed bent base on body
Some wind speed probes are set.
As preferably, body includes support, pacifies in various location in short transverse at support
Filling several framed bent bars, wind speed probe is arranged on framed bent bar.
As preferably, the front end of wind speed probe is pitot tube structure, and rear end connects micro-pressure sensor.
As preferably, body and framed bent base are mutually perpendicular to arrange.
As preferably, the cable being provided with wire casing, micro-pressure sensor and outfit on body is placed in line
In groove.
As preferably, framed bent base is provided with bolt hole.
As preferably, framed bent bar is provided with installing hole.
As preferably, the cable that micro-pressure sensor is equipped with is connected to main cables.
As preferably, insulating cement is wrapped up at the two ends of the cable that main cables and micro-pressure sensor are equipped with
Band.
As preferably, framed bent base is rectangular plate-like structure.
Transient state wind speed measurement at multiple points framed bent that this utility model relates to is it can be avoided that owing to pipeline affects
The problems such as the blast decay produced and asynchronous collection, can select to measure position simultaneously as required
Put, it is achieved the transient state of multiposition blast is disposably measured, be greatly saved workload, and tie
