Problems solved by technology

Since the manufacturer does not produce a movable lifting device corresponding to the three-dimensional particle image velocimeter, it is inconvenient to use the particle image velocimeter to measure the flow velocity in test equipment such as water tanks, water tunnels, wind tunnels, shock tubes, and plexiglass pipes in the laboratory. It is urgent to develop a device that can move and lift the particle image velocimeter

Abstract

The invention relates to a lifting trammer for a three-dimensional particle image velometer. The lifting trammer comprises a first trammer for placing a laser emitter and a generator, a second trammer for placing a side view type CCD camera, a third trammer for placing an overlooking-type CCD camera and a fourth trammer for placing an optical arm and an optical source; each trammer comprises a belt pulley and a free movable stand; the stand is provided with a working platform for placing a corresponding part of the velometer; and the working platform is connected with the stand through a lifting mechanism. The lifting trammer has the advantages that the lifting trammer freely lifts and moves the three-dimensional particle image velometer and has convenient use and low cost.

Description

technical field [0001] The invention relates to a movable lifting device used in conjunction with a three-dimensional particle image velocimeter, in particular to a lifting trolley for a three-dimensional particle image velocimeter. Background technique [0002] The three-dimensional particle image velocimeter can measure the three-dimensional instantaneous velocity field of fluid flow, and the measured fluid is incompressible fluid or compressible fluid. Specifically, it can be used for the measurement of liquid, gas and multiphase flow. It belongs to non-contact measurement, has no interference to the flow field, and has high precision. It is currently the most advanced flow velocity measurement instrument in the world. [0003] The main components of the three-dimensional particle image velocimeter are: laser emitter and its generator, side-view CCD camera and top-view CCD camera, optical arm and sheet light source system. At present, there are mainly two companies that ...
