Embodiment

[0035] Such as Figure 1 to Figure 3 As shown, a portable bracket used for measuring fluid velocity in a pipeline includes three parts: a combined support platform 1 that can be turned over by 90°, a positioning observation plate 2, and a tripod 3. The tripod 3 is a telescopic portable tripod.

[0036] The support table 1 consists of two parts: an overturning support plate 15 and a bearing plate 16, which are combined by a rotating shaft 11 and a locking knob 12, and can be adjusted and positioned arbitrarily within 90° according to the position of the measuring hole on the pipeline ; Fix the measuring instrument in the "C" groove of the flip support plate 15 by adjusting the fixing bolt 14; determine and grasp the directionality of the measurement through the bubble level 13. Generally, the cross-section of the test instrument is circular, so it is fastened with C-shaped grooves and C-shaped end bolts.

[0037] The rotating shaft 11 and the locking knob 12 are assembled toge...

Abstract

The invention relates to a portable support for measuring velocity of fluid in a pipeline. The portable support comprises a support platform and a tripod. The bottom portion of the support platform isconnected to the top portion of the tripod. The tripod adopts a stable cross arm to support a positioning observation disc. The support platform and the positioning observation disc are respectivelyprovided with a positioning observation hole for connecting with a measuring instrument. The support platform comprises a turnover support disc and a bearing disc. The bottom portion of the bearing disc is connected with the tripod; the turnover support disc is in rotation connection with the bearing disc; and the included angle between the turnover support disc and the bearing disc is adjusted between 0 degree and 90 degrees. Compared with the prior art, the portable support can be suitable for any working environment, any shape of pipe, any position and any form of measurement holes, avoidsthe problems of difficult control of desired direction and large errors due to shaking of the measuring instrument during traditional manual operation, and does not need manual holding; and the portable support has the advantages of being simple and durable in structure, safe to use, stable in positioning, convenient to operate, lightweight and portable, resistant to corrosion, heat and wear and high in applicability.

Description

technical field [0001] The invention relates to a measurement support, in particular to a portable support for measuring fluid velocity in a pipeline. Background technique [0002] In industrial production, the wind speed measurement research of production pipelines plays a vital role in safety production, efficiency improvement, and environmental improvement. Improvement is extremely important. When measuring the velocity of the fluid in the pipeline, it is required that the measuring instrument must be rigidly fixed and its measurement direction must be guaranteed. For the pipeline, a series of measurement points must be on the same straight line. [0003] At present, many engineering and production units use Pitot tubes to measure the velocity of fluid in pipelines. Pitot tubes are used to insert into the reserved measuring holes on the pipeline. Often when the position of the measuring point is changed by plugging and unplugging the Pitot tube, it is easy to shake back...
