Abstract
The utility model relates to a dynamic balance detector for badmintons, which comprises a box body. A cylindrical air hole is arranged in the box body; a blower controlled by a digital frequency converter is arranged in the air hole; air blown out by the blower is in a vertical and upward direction; a background plate perpendicular to the ground is arranged in the air hole; the center of the background plate is provided with a vertical center line; both sides of the center line are provided with vertical lines perpendicular to the center line to be used as scale marks; the air hole is made of transparent materials; the side surface of the air hole is provided with a camera; and the camera is connected to a state display arranged on the box body. The badmintons are vertically placed into the air hole of the dynamic balance detector for the badmintons along the center line of the background plate to detect the deviating condition of the badmintons from the center line, the fly condition of the badmintons can be accurately simulated, and the dynamic balance performance of the badmintons can be easily judged under the condition of no damage on the badmintons. The utility model has the advantages of simple structure, simple method, low cost and easy popularization, and is suitable for production.
Description
Technical field:
The utility model relates to the shuttlecock experimental provision, is a kind of badminton dynamic balancing pick-up unit specifically.
Background technology:
Shuttlecock is in manufacture process, because the various accumulations of error, the marquis can cause the finished product shuttlecock abnormal rocking to occur in flight course sometimes, swing.Such shuttlecock must be picked out, and can not normally bring into play otherwise can influence sportsman's technology as official ball.Therefore the dynamic balance performance of shuttlecock is one of most important technical indicator of shuttlecock.To choose this shuttlecock in the past, and need to engage veteran sportsman, detect the state of flight of shuttlecock with real play or service robot service method.Doing like this needs and can please arrive the professional, spend higherly, and labour intensity is big, and efficient is lower, also easy damage shuttlecock.
The utility model content:
The utility model provides a kind of badminton dynamic balancing pick-up unit, can simulate the shuttlecock state of flight, judges that its flight path has bias free, thereby judges the badminton dynamic balancing performance.
The technical solution adopted in the utility model:
The badminton dynamic balancing pick-up unit is characterized in that: have a casing, a vertical wind tunnel is arranged in the casing, the wind-tunnel bottom is equipped with the variable frequency control blower fan, and the wind that blower fan blows out vertically upward; Background board is installed in the wind-tunnel, and the background board subscript is marked with center line, and there is scale mark the center line both sides; Wind-tunnel is that transparent material is made, and the wind-tunnel side is equipped with camera, and camera is connected to the status displays that is installed on the casing.
Described badminton dynamic balancing pick-up unit is characterized in that: described wind-tunnel and arranged on left and right sides is installed infrared correlation tachogenerator.
Badminton dynamic balancing detection method is characterized in that may further comprise the steps:
(1), a vertical wind tunnel is set in casing, in the wind-tunnel installed inside one background board is arranged, the background board subscript is marked with center line, there is scale mark the center line both sides, wind-tunnel bottom is equipped with blower fan, and the wind-force of vertical direction is provided to wind-tunnel;
(2), shuttlecock is vertically put into wind-tunnel along the background board center line;
(3), regulating rotation speed of fan makes shuttlecock keep the stable suspersion state;
(4), camera photograph shuttlecock in wind-tunnel state and be transferred to status displays, read the number of division that shuttlecock departs from the background board center line by status displays, thereby judge whether this ball transient equilibrium index qualified.
Advantage of the present utility model:
The utility model adopts newly-designed construction of wind tunnel, can accurately simulate the flight situation of shuttlecock, easily judges the dynamic balance performance of shuttlecock under the situation of not damaging shuttlecock; In the wind-tunnel and arranged on left and right sides infrared correlation tachogenerator is installed, under the effect of shuttlecock wind-force in wind-tunnel, be rotated, at this moment the space between shuttlecock hair stalk obstructs with hair constantly allow infrared correlation tachogenerator light path by with disconnection, by the unit of account number of times that light path disconnects and passes through in the time, can calculate shuttlecock rotation rotating speed.The utility model is simple in structure, and method understands that cost is lower, is highly suitable for producing, and is easy to promote.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
Referring to Fig. 1.
As figure one badminton dynamic balancing pick-up unit is arranged: have a casing 1, a cylindrical wind-tunnel 2 is arranged in the casing 1, the blower fan 3 by digital frequency converter 6 controls is housed in the wind-tunnel 2, the wind that blower fan 3 blows out vertically upward; One background board 4 perpendicular to ground is installed in the wind-tunnel 3, and there is vertical center line at background board 4 centers, and there is the vertical curve parallel with center line on the center line both sides as scale mark; Wind-tunnel 2 is made for transparent material, and wind-tunnel 2 sides are equipped with camera 7, and camera 7 is connected to the status displays 8 that is installed on the casing.
Claims (2)
