Description

TECHNICAL FIELD

[0001] The utility model relates to aviation obstruction light technical field especially, relates to a low light intensity obstruction light for wind driven generator. BACKGROUND

[0002] With the rapid development and application of wind power generation technology, more and more wind driven generators appear on the horizon. The height of these large structures often exceeds the height limit of aviation safety regulations, so aviation obstruction lights must be installed to ensure flight safety. However, the support tube of the wind driven generator is usually a high-strength circular steel tube structure, which brings challenges to the installation of traditional aviation obstruction lights. The traditional obstruction light installation method usually relies on pre-designed or post-welded metal brackets, but on wind driven generators, due to the design characteristics of the support tube and the complexity of high-altitude work, both methods are difficult to implement:

[0003] Pre-designed bracket: adding obstruction light installation brackets during the design stage of the wind driven generator will increase design costs, and once the design is determined, it will become very difficult to change later.

[0004] Post-welded bracket: welding operations on already installed wind driven generators not only increase construction difficulty, but also have high risks associated with high-altitude work, and welding may affect the structural integrity of the wind driven generator.

[0005] In addition, some obstruction light products in the prior art may rotate or shift after installation due to wind, gravity or other external forces, causing the light emitting angle to deviate from the horizontal position and affecting the effect of aviation safety indication. In addition, some products have poor waterproof performance and are easily eroded by rainwater, and the risk of damage to internal electronic components by moisture is high.

[0006] Therefore, a low light intensity obstruction light for wind driven generators is proposed to solve the above problems. SUMMARY

[0010] More preferably, the shell is provided with an adjusting frame on both sides, the adjusting frame is provided with an adjusting groove, and the magnet is installed at the end of the adjusting frame. By changing the position of the adjusting frame, the distance between the magnet and the pipe wall of the wind driven generator is adjusted, thereby realizing the universality of the obstruction light for various wall thicknesses of the fan pipe wall.

[0011] Further, the surface of the magnet is coated or plastic encapsulated, which not only prevents the magnet from oxidizing, but also prevents the magnet from being broken by instantaneous impact on the pipe wall during installation, thereby preventing safety accidents. The magnet is preferably a neodymium magnet with high magnetism.

[0012] Further, the shell is provided with a cover plate at the tail, the cover plate is connected with the shell through a sealing ring, and the plug is arranged at the middle position of the cover plate.
