[0015] The embodiments of the present utility model are described in detail below with reference to the accompanying drawings.
[0016] An electric cylinder for wind tunnel experiments, such as Figure 1-Figure 2 As shown, it includes a base 1, a motor 2, a rotating disk 3, a connecting column 4, a fixing plate 5, an electric rod 6, a handle 7, a rotating member 8, a placement plate 9, a clamping assembly 10 and a connecting plate 11. The motor 2 is connected to the upper side of the base 1, the rotating disk 3 is connected to the output shaft of the motor 2, the connecting column 4 is connected to the upper side of the middle of the rotating disk 3, the fixing plate 5 is connected to the upper side of the connecting column 4, the front and rear sides and the left and right sides of the connecting column 4 are slidably connected to the electric rod 6, the lower side of the electric rod 6 is slidably connected to the rotating disk 3, a plurality of bolts are arranged on the electric rod 6, and the bolts are threadedly connected to the rotating disk 3. A handle 7 is connected to the outside of the electric rod 6, and a rotating part 8 is rotatably connected to the telescopic end of the electric rod 6. A placement plate 9 is connected to the rotating part 8, and a clamping assembly 10 is connected to the placement plate 9. The clamping assembly 10 includes a connecting rod, an upper clamp, a lower clamp and a torsion spring. A connecting rod is connected to the upper side of the placement plate 9, an upper clamp is connected to the upper part of the connecting rod, and a lower clamp is rotatably connected to the lower part of the connecting rod. A torsion spring is connected between the lower clamp and the connected connecting rod. A connecting plate 11 is slidably connected to the front and rear sides and the left and right sides of the fixed plate 5, and the connecting plates 11 are connected to adjacent electric rods 6.
[0017] When using the utility model, firstly, the base 1 is placed in the wind tunnel test area, and then the wind tunnel test model is fixed by the fixing plate 5 on the connecting column 4 to meet the static measurement requirements of the wind tunnel test. When the wind tunnel test model needs to be dynamically simulated, the position of the electric rod 6 can be adjusted by sliding the handle 7 according to the model specifications, driving the connecting plate 11 to slide on the fixing plate 5 to adapt to models of different specifications. After the adjustment, the electric rod 6 is fixed by the bolt, and then the lower clamp in the clamping assembly 10 is rotated to rotate the lower clamp on the connecting rod, and the torsion spring is deformed. The wind tunnel test model is then placed between the lower clamp and the upper clamp. After placement, the lower clamp is released and restored through the torsion spring, driving the lower clamp to reset, so that the wind tunnel test model is fixed between the lower clamp and the upper clamp. Then, the electric rod 6 is started to push the rotating part 8 to move up and down, driving the placement plate 9 to move up and down, so that the wind tunnel test model is tilted. When conducting the experiment, the motor 2 can be started to drive the rotating disk 3 to rotate, so that the wind tunnel test model rotates, thereby achieving a multi-angle and all-round display of the wind tunnel test model, which is convenient for improving the accuracy and credibility of the wind tunnel test data.
