Description

Technical Field

[0001] This utility model relates to the field of wind turbine blade transportation technology, specifically a wind turbine blade transportation device. Background Technology

[0002] The blade is the most basic and critical component of a wind turbine. Its good design, reliable quality, and superior performance are the decisive factors in ensuring the normal and stable operation of the unit. Harsh environments and continuous operation place high demands on the blades, requiring them to be lightweight with optimal fatigue strength and mechanical properties, able to withstand extreme conditions such as storms and random loads, and possess normal elasticity, rotational inertia, and vibration frequency characteristic curves. The blades must also have good load stability transmitted to the entire power generation system, and must not break and fly off under centrifugal force in the event of runaway operation, nor break under wind pressure, nor generate strong resonance that would affect the entire wind turbine unit below the runaway speed. The blade material must ensure a smooth surface to reduce wind resistance; a rough surface will be torn by the wind. The blades must not generate strong electromagnetic interference or light reflection, must not produce excessive noise, and must be corrosion-resistant, have good performance against ultraviolet radiation and lightning strikes, and have low cost and minimal maintenance expenses.

A first limiting rod is welded to the inner wall of both the first and second fixing frames, and a first through hole is formed in the inner wall of the first limiting rod. A first threaded hole is engraved inside the first limiting rod. A second through hole is formed in the inner wall of the third limiting rod, and a second threaded hole is engraved inside the third limiting rod. A second bolt is rotatably installed in both the second and first threaded holes, and a first nut is rotatably installed on the second bolt. A connecting rod is welded to the side surface of the second limiting rod, and the connecting rod is slidably sleeved in the second through hole of the third limiting rod. This invention has the advantages of convenient operation, easy fixing, and better practicality.
