The pressure in the described tracer agent airtight container and the switching of electrically operated valve be by the outer operating personnel's control of fluid, can be regularly and/or not timing ground by electrically operated valve to treating that fluid measured sprays into tracer agent.Since the tracer agent color with treat that fluid measured has obvious difference, good followability is arranged again, thereby can indicate the direction and the flow velocity of fluid flow line to be measured in real time.
The special measurement alignment lens is certain zone at center with the airtight container electrically operated valve in the described fluid that has a scale, can see and take process and the tracer agent that tracer agent sprays clearly from described measurement camera lens and sealing camera and follow the situation for the treatment of measured fluid movement.The distance that described measurement camera lens and airtight container electrically operated valve should be maintained fixed, the division of measuring the reading scale of scribing in advance on the camera lens calculates by geometric relationship according to the enlargement factor of distance and camera lens itself, the tracer agent that makes lattice of scale on the camera lens just in time equal the electrically operated valve ejection unit distance of moving.
Owing in described sealing camera, video recorder and the computing machine synchronous clock is housed all, can Direct observation except from display the flow direction for the treatment of fluid measured that shows of tracer agent, flow velocity, computer system can be sampled to distance that flows and the time continuous synchronization ground that is consumed, real-time Fluid Computation flow velocity, and result of calculation both had been presented on the device curtain, be kept at again in the calculator memory, reach the purpose of real-time demonstration, record flow velocity, the flow direction.
The flow velocity that fluid flow state of take, recording and calculating show can both also can be recorded in the memory device (video-tape, calculator memory) automatically from Direct observation on the screen, for research afterwards.
Moving of measuring system in the fluid can be finished by the manipulation submersible motor and the pushing mechanism of controller and electrical connection with it by operating personnel.The distance and the speed that promote and/or rotate, operating personnel can oneself control, so that follow the trail of the flow direction and the flow velocity for the treatment of fluid measured handyly.Operating personnel can also command, control the work of surveillance by controller.
Among the present invention, also can adopt in two or more fluids and handle and measuring system, to accelerate the progress of work.
The present invention not only is suitable for the measurement of steady flow, and is suitable for existing various undercurrents, seepage, and non-constant fluid three-dimensional flow field active and/or Sinks flows to, the measurement of flow velocity; And do not need rate (mark) fixed, visual, in real time directly measurement fluid three-dimensional flow to, flow velocity; Integrate automatic walking, automatically shoot with video-corder image, automatically record, calculate, show and storage data etc. multi-functional; Detection data is accurate, the detection efficiency height.
Use the present invention, eliminating safe hidden trouble, and detect the dam leakage piping for the seepage of detecting reservoir, dam, Jiang Di, the hidden danger of in time finding out and remove the dangerous condition, flood-fighting all has very high using value.
