Description

Technical Field

[0001] The utility model relates to the technical field of wind power generation equipment, in particular to a wind turbine structure. Background Art

[0002] A wind turbine is a turbine that uses wind energy as power. An aerospace research institute in Wilbraham, Massachusetts, USA has developed a wind turbine, and now there is a small wind turbine on the market that is easy to carry and can be used in the wild.

[0003] The prior art (patent number: CN220267861U) discloses a wind turbine structure, including a body, an outer side of the body is provided with a mounting groove and an electrical port, one end of the body is provided with a rotating shaft, one end of the rotating shaft is provided with a mounting mechanism, the mounting mechanism includes a movable groove and a locking groove, a first rotating shaft is provided inside the movable groove, a fixing hole is opened inside the rotating shaft, a fan blade is rotatably connected to the outer side of the first rotating shaft through a sleeve, a pressure plate is fixedly connected to one side of the sleeve, a fixing seat is detachably connected to one side of the rotating shaft, a fixing bolt is provided on one side of the fixing seat, and the fixing hole is engaged with the fixing bolt. The beneficial effect of the utility model is that by setting up an installation mechanism, including a movable groove, a first installation axis, and a fixing hole, first, the machine body and the support rod need to be taken out of the backpack, and then the machine body and the support rod need to be fixed by means of a threaded connection through the installation block. Then, since the initial state of the fan blade is placed in the installation groove, it is necessary to press the fan blade downward to make the fan blade perpendicular to the machine body, and then place the pressure plate into the locking groove. After that, it is only necessary to thread the fixing seat to the inside of the fixing hole through the fixing bolt to quickly and effectively fix the fan blade. However, when it is necessary to store it, it is only necessary to remove the fixing seat to quickly and effectively retract the fan blade from the installation groove for easy storage.

[0004] The existing wind turbine structure has the following disadvantages. Since the fan blade installation process of the existing equipment is relatively cumbersome and the height of the existing small equipment is fixed, the use of the equipment in low-lying locations is not ideal, which makes the equipment have certain limitations. Therefore, we propose a new wind turbine structure. Utility Model Content
