Description
Technical field
Measure the equipment of sluicing overflow shape in a kind of hydraulic model test of the present invention, belong to the hydraulic model test field.
Background technology
In hydraulic model test, to measure the trajectory nappe of flip trajectory bucket, in order to confirm the overflow form, the position of falling into water through regular meeting.These measured values are mainly skyborne laterally in order to judge overflow, draw back longitudinally, collision etc., in design, help to confirm and bank build, subtended angle etc. are chosen in optimization.The mode of common in the prior art description overflow form is photograph or video recording, but because photograph and video recording have nonlinear distortion, can not accurately reflect the overflow form.In test operation, on minimodel, there is the people to utilize glass plate to place the overflow side to draw; But also exist the different persons of describing to produce the problem of different rendering results; Simultaneously, when model is big, can't find suitable glass plate to describe complicated operation.
The utility model designs for overcoming the above problems just.

Horizontal guide rail is a double track up and down, is fixed on the model side in a horizontal manner, contains the side of whole tested overflow up and down with the formed face of horizontal length;
Vertical guide rail is a single track, and two ends are fixed on the horizontal guide rail with sliding sleeve, and sliding sleeve can slide on horizontal guide rail;
Level range finding dish is fixed on an end of horizontal guide rail; Be fixed on the end that overflow penetrates generally speaking;
The horizontal laser light stadimeter is fixed on the vertical guide rail, is the level of state its range finding laser vertical sensing level range finding dish;
Horizontal stepper motor is fixed on an end of horizontal guide rail, links to each other with vertical guide rail through tooth bar, and horizontal stepper motor promotes vertical guide rail and slides along horizontal guide rail;
Vertical laser range finder is fixed on and horizontal laser light stadimeter same position, with the horizontal laser light stadimeter in vertical state, its range finding laser vertical directed in orthogonal range finding dish;
The depth laser range finder is fixed on the vertical range finding dish, and vertical range finding dish is fixed on the vertical guide rail with sliding sleeve, and sliding sleeve can slide on vertical guide rail;
Vertical range finding dish links to each other with the vertical stepper motor of vertical guide rail one end through tooth bar, and vertical stepper motor promotes vertical range finding rim vertical guide rail and slides;
The laser beam of curtain wall in order to reflection depth laser range finder is set on the guide rail opposite.
The beneficial effect of the utility model is:
1, the automatic equipment of measuring sluicing overflow shape in a kind of new more accurately more reliable hydraulic model test is provided;
2, can the work of measurement overflow be carried out automatically through setting program.
