Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic load test equipment, in particular to a wind generating device for pneumatic load simulation. Background Art

[0002] A pneumatic load refers to the force and moment acting on an object (such as a wind turbine blade, a high-speed train body, etc.) under the action of fluid (such as air) dynamics. The generation of these forces and moments is due to the interaction between the fluid and the object, including factors such as fluid flow, pressure distribution, and the shape, size, and motion state of the object.

[0003] Currently, during the process of conducting dynamic air load tests, wind power equipment is required to provide corresponding wind resistance to the test object. However, the currently used wind power equipment can only blow wind from a single direction and cannot adjust the wind direction, resulting in certain limitations during the test. Therefore, we propose a wind generating device for pneumatic load simulation to solve the above-mentioned problems. Summary of the Utility Model

The wind generating device further includes:

[0007] An air suction mechanism, the air suction mechanism penetrates through the bracket and is connected to the bracket, and one side of the air suction mechanism extends into the air inlet cylinder and is connected to the top of the air inlet cylinder;

[0008] A support mechanism, the support mechanism is installed on the other side of the top of the base;

[0009] An air exhaust mechanism, the blowing mechanism is connected to one end of the hose, and the blowing mechanism is installed on the support mechanism.

[0010] In a possible design, the air suction mechanism includes a driving motor fixedly installed on the inner wall of the top of the bracket. The output shaft of the driving motor extends above the bracket and is connected with a gear assembly. The gear assembly is connected to the top of the air inlet cylinder. A driving shaft is installed on the gear assembly. A net plate is fixedly installed in the air inlet cylinder. The bottom end of the driving shaft extends into the air inlet cylinder and is fixedly installed with blades.

[0011] In a possible design, the gear assembly includes a gear fixedly installed on the output shaft of the driving motor. A rotating ring is rotatably connected to the top of the air inlet cylinder. A plurality of mounting rods are fixedly installed at equal intervals on the inner side of the rotating ring. The plurality of mounting rods are all fixedly connected to the driving shaft. A toothed ring is fixedly sleeved on the rotating ring. The gear meshes with the toothed ring.

[0012] In a possible design, the support mechanism includes an arc-shaped cover fixedly installed on the other side of the top of the base. A sliding plate is slidably connected in the arc-shaped cover. A fixed rod is fixedly installed on the top of the sliding plate. The top end of the fixed rod extends above the arc-shaped cover and is fixedly installed with an L-shaped frame. An installation plate is fixedly installed on the top of the L-shaped frame. The air blowing mechanism is installed on the top of the installation plate.

[0013] In a possible design, a plug rod is slidably connected through the L-shaped frame. An arc-shaped positioning plate is fixedly installed on one side of the arc-shaped cover. The L-shaped frame is slidably connected with the arc-shaped positioning plate. A plurality of slots are arranged at equal intervals on the top of the arc-shaped positioning plate. The bottom ends of the plug rods are respectively movably clamped with the plurality of slots. A tension spring is sleeved on the plug rod and is fixedly connected with the top end and the bottom end of the plug rod and the top of the L-shaped frame respectively.

[0014] In a possible design, the exhaust mechanism includes an exhaust hood fixedly installed on the top of the installation plate. One side of the exhaust hood is fixedly connected with one end of a hose. Two flow guiding plates are symmetrically rotatably connected in the exhaust hood. One side of the flow guiding plate extends to the outside of the exhaust hood.

[0015] In a possible design, a limiting frame is fixedly installed on the top of the exhaust hood. An adjusting plate is slidably connected in the limiting frame.

At this time, under the meshing drive with the toothed ring, the rotating ring can be driven to rotate. At this time, the drive shaft can be driven to rotate, providing a driving force for the rotation of the blades, so that the blades rotate. Then, the suction force of the blades can be used to suck the external gas into the air intake cylinder, so as to convey the gas in a directional manner, so that the gas is conveyed by the hose to the exhaust hood, and then the gas is discharged through the exhaust hood to provide a stable air volume for the starting load test.
