Description
Technical field
The utility model relates to mechanics experiment platform, in particular to a kind of novel fluid dynamics experimental device.
Background technique
In hydromechanical teaching, experimental implementation can deepen understanding of the student for fluid analysis.Current
Air-flow fluid experiment device in, it is often necessary to the dump angle degree of ventilation shaft is adjusted, in order to observe different air-flow streams
The stress of dynamic angle.When adjusting ventilation shaft, since ventilation shaft is fixed by the bracket on experimental bench,
When adjusting ventilation shaft, operate comparatively laborious.
Utility model content
The technical problem to be solved by the utility model is to provide a kind of novel fluid dynamics experimental devices, which can
The dump angle degree in ventilation shaft is quickly adjusted, the cumbersome of traditional approach is avoided, improves conventional efficient.
A kind of to achieve the above objectives, the present invention provides the following technical solutions: novel fluid dynamics experimental device,
Including rack, the rack is equipped with desktop, and the desktop is operating table surface, is equipped with ventilation duct by bracket on the rack
The one end in road, the ventilation shaft is air inlet, and the other end is gas outlet, and the end face of the air inlet is fixedly installed with one piece admittedly
Fixed board, the center of fixed plate are fixedly installed with a ball seat, and the sphere that can be rotated around the ball seat centre of sphere is inlaid in ball seat,
Sphere is equipped with through hole, and internal screw thread is equipped in through hole, connects a blast pipe in through hole, the sphere is far from ventilation duct
The side in road is connected with one end of an adjusting rod, and the other end of adjusting rod is free end, is equipped with several biographies in ventilation shaft
Sensor, the sensor are connect with the computer of installation on the table.
Preferably, it is connected between adjusting rod and sphere using articulated manner.
Preferably, through hole is located at the center of sphere, and the axis of the through hole is overlapped with the axis of sphere.
Preferably, ESD pad is equipped on desktop.
Preferably, the lower section of rack is equipped with drawer.
By adopting the above technical scheme, the utility model is when adjusting the incident angle of air-flow, it is only necessary to pull adjusting rod, lead to
The adjustment effect of toning pole, so that sphere carries out corresponding angular adjustment in ball seat, avoiding the need for will be entire logical
Air piping is adjusted cumbersome, to improve conventional efficient.
Detailed description of the invention
Fig. 1 is the utility model structure diagram；
Fig. 2 is the structural schematic diagram of the utility model sphere；
Fig. 3 is the assembling schematic diagram of ball seat and sphere.
Specific embodiment
With reference to the accompanying drawing, by the description of the embodiment, being described further to the utility model:
As shown in Figures 1 to 3, a kind of novel fluid dynamics experimental device of the utility model, including rack 1, rack 1 are equipped with
Desktop 2, desktop 2 are operating table surface, pass through bracket 3 on rack 1 and are equipped with ventilation shaft 4, one end of ventilation shaft 4 is air inlet
41, the other end is gas outlet 42, and the end face of air inlet 41 is fixedly installed with one piece of fixed plate 5, the fixed peace in the center of fixed plate 5
Equipped with a ball seat 6, the sphere 7 that can be rotated around 6 centre of sphere of ball seat is inlaid in ball seat 6, sphere 7 is equipped with through hole
8, through hole 8 is located at the center of sphere 7, and the axis of through hole 8 is overlapped with the axis of sphere 7, sets in through hole 8
There is internal screw thread, through hole 8 is interior to connect a blast pipe 11 by internal screw thread, and sphere 7 is hinged with one far from the side of ventilation shaft 4
One end of root adjusting rod 9, the other end of adjusting rod 9 are free end, are equipped with strain gauge, the sensing in ventilation shaft 4
Device is connect with the computer 10 being mounted on desktop 2.
The utility model can also be equipped with ESD pad on desktop 2, in order to prevent electrostatic.Simultaneously in rack
Drawer 12 is installed in 1 lower section, convenient for experiment equipment being placed in drawer 12 and is kept after the completion of experiment.
The utility model is when adjusting the incident angle of air-flow, it is only necessary to pull adjusting rod 9, pass through the adjusting of adjusting rod 9
Effect, so that sphere 7 carries out corresponding angular adjustment in ball seat 6, avoids the need for adjusting entire ventilation shaft 4
That saves is cumbersome, to improve conventional efficient.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, without departing from the concept of the present invention, various modifications and improvements can be made, these all belong to
In the protection scope of the utility model.
