Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is mesh sheet fixture structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, proving installation of the present utility model comprises dynamic water tank 1, mesh sheet stationary installation 2, electricity-saving lamp 3, angular instrument 4 and gauge 5.Dynamic water tank 1 comprises flume frame and is arranged on the clear glass cell wall in flume frame, and flume frame is iron structure, and has certain intensity.
Angular instrument 4 is arranged on the clear glass cell wall of dynamic water tank side, and angular instrument 4 is a transparent semicircle angular instrument, to facilitate in mesh sheet test process, clearly can see mesh sheet deflection angle clearly.Gauge is positioned on the position of this semicircle angular instrument 90 °, adopts transparent material.
As shown in Figure 2, mesh sheet stationary installation 2 comprises T-shaped support 6 and mesh sheet fixed mount 7, wherein, mesh sheet fixed mount 7 is arranged on the lower end of T-shaped support 6, the upper end of T-shaped support 6 is fixed in flume frame, mesh sheet fixed mount 7 is arranged in dynamic water tank 1, and mesh sheet fixed mount 7 is parallel with gauge 5 near the side alignment criteria chi 5 of gauge.When carrying out the test of mesh sheet hydrodynamic force, mesh sheet to be measured be arranged on mesh sheet fixed mount 7, mesh sheet stationary installation 2 adopts titanium alloy structure, can reduce resistance suffered when carrying out hydrodynamic force test.
Described electricity-saving lamp 3 is positioned at flume frame 1 surrounding, and is uniformly distributed, and electricity-saving lamp 3 is fixed on flume frame 1 surrounding by the plastics light trough of transparent material, and electricity-saving lamp is incandescent lamp, voltage 220v, and color is white.By installing energy saving lamp 3, the changes shape of mesh sheet to be measured in water can be seen comparatively clearly clearly, and then improve the accuracy of test.
When the utility model uses, first mesh sheet to be measured is fixed on the mesh sheet fixed mount 7 of mesh sheet stationary installation 2, then by T-shaped support 6, mesh sheet stationary installation 2 is arranged in flume frame.Regulate mesh sheet stationary installation 2, mesh sheet fixed mount 7 is alignd with gauge 5 near the side of gauge, and parallel with gauge 5.Be arranged on by electricity-saving lamp 3 in the plastics light trough of flume frame 1 surrounding, switch on power energising.After having operated above, open dynamic water tank, setup test.Under the continuous impact of current, can there is deflection in various degree in mesh sheet, by the angle of angular instrument record mesh sheet deflection, decreases mesh sheet in test process due to the error that drift angle produces, improve the precision of test.
The utility model by installing angular instrument on dynamic water tank sidewall, can in mesh sheet hydrodynamic force test process, the angle of accurate recording mesh sheet deflection, and at flume frame surrounding installing energy saving lamp, the changes shape of mesh sheet in water can be seen comparatively clearly clearly, and then improve the accuracy of experiment test.
