Embodiment
Below in conjunction with the accompanying drawing in example of the present invention, be clearly and completely described the technical scheme in example of the present invention, obviously, described example is only the present invention's part example, instead of whole examples.Based on the example in the present invention, those of ordinary skill in the art, not making the every other example obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Fig. 1 ~ 5, a kind of wind spout test unit for building wind engineering, comprises column 1 and motor 7, column 1 top is provided with longeron 2, longeron 2 is connected with crossbeam 6, and longeron 2 is provided with the roller 3 along longeron movement, and roller 3 is connected with brace summer 4, brace summer 4 is connected with vortex generator 5, crossbeam 6 is provided with motor 7, and motor 7 drives driving wheel 8 to rotate, and brace summer 4 is provided with the engaged wheel coordinated with driving wheel, be provided with platform 9 below vortex generator 5, platform 9 is arranged on jacking gear 10.Wherein, described driving wheel and engaged wheel are preferably sprocket wheel, and driving wheel drives engaged wheel to rotate by chain 14, and described jacking gear 10 is hydraulic cylinder or sleeve.
The present invention can simulate the wind spout of different conditions, and its regulative mode is as follows:
1. being rotated by motor 7 drives driving wheel 8 to rotate, time driving wheel 8 rotates, brace summer 4 is driven to move along longeron 2 by engaged wheel, and then change vortex generator 5 position in the horizontal direction, time motor 7 rotating speed is different, the translational speed of vortex generator 5 is different, namely have adjusted the horizontal movement velocity of vortex generator 5.Wherein motor 7 is DC speed-regulating motor, can be adjusted the rotating speed of motor 7 by silicon rectifier speed regulator 13.
2., by regulating the height of jacking gear 10, the vertical range that platform 9 and vortex generator 5 export can be regulated, and building model is arranged on platform 9, therefore can adjust the vertical range between building model and vortex generator.Meanwhile, because platform 9 is supported by four jacking gears 10, by regulating the height of different jacking gears 10, the angle between building model and vortex generator can also be adjusted, and then simulate imperial whirlwind with the state in different angle impacts houses.
As preferably, described vortex generator 5 comprises housing 5-5 and air duct 5-3, housing 5-5 is connected with axial flow blower 5-1, is provided with honeycomb 5-4 below axial flow blower 5-1, forms wind groove 5-6 between air duct 5-3 and housing 5-5, wind groove 5-6 inner deflector 5-2.Axial flow blower 5-1 is frequency conversion fan, after being connected, can change the travelling speed of axial flow blower 5-1 with AC converter 12, and then the wind speed size of adjustment simulation wind.
Vortex generator 5 principle of work is as follows: time axial flow blower 5-1 starts, the air of vortex generator lower end is drawn into top through honeycomb 5-4, this part gas is after fair water fin 5-2, define the wind spout of emulation mode, downward through wind groove 5-6, blow on the building model of platform 9.By the rotating speed of adjustment axial flow blower 5-1, the wind intensity of wind spout can be adjusted.
As a step is preferred again, radially, these fair water fins 5-2 belongs to the tangent line of same circle to some fair water fin 5-2, can ensure that the wind through fair water fin 5-2 is modeled to wind spout, blow out with vorticity.By the angle of adjustment fair water fin 5-2, the tangential wind speed of wind spout can be regulated.
In addition, in order to strengthen the stability of whole device, between crossbeam 6 and column 1, bearing diagonal 11 is also connected with.
Described platform 9 is wooden test platform.
