Description

Technical Field

[0001] This utility model relates to the field of seat belt technology, specifically a weather-resistant seat belt for wind power generation systems. Background Technology

[0002] Wind turbine generators are typically located in harsh environments such as coastal or offshore areas. When maintenance personnel perform high-altitude operations such as tower climbing and nacelle maintenance, their safety harnesses not only need to provide fall protection but also face severe climatic challenges such as strong ultraviolet radiation, salt spray, high humidity, and extreme temperature differences. The webbing and metal components of ordinary safety harnesses are prone to aging, strength reduction, and corrosion after prolonged exposure to such environments, posing serious safety hazards. Wind turbine maintenance procedures are complex, requiring the carrying of various tools, and the working space is confined, placing higher demands on the comfort, functionality, and convenience of safety harnesses.

The front waist pad and the back waist pad are provided with several loops. The waist belt passes through the loops. The front waist pad corresponds to the position of the adjustment buckle and the waist loop on the waist belt. The back waist pad extends from the left side of the waist belt to the right side of the waist belt. The lower left and right sides of the waist belt are connected to leg straps, which are provided with adjustment buckles and leg pads.

[0004] The shoulder straps, waist belt, back straps, chest straps, and leg straps are coated with polyurethane on their outer sides.

[0005] One end of the buffer bag is connected to a fixing ring via an O-ring, and the other end of the buffer bag is connected to one end of a safety rope via an O-ring. The other end of the safety rope is equipped with a buckle.

[0006] The fixing ring, waist ring, and back lifting ring are D-shaped rings and made of weathering steel.

[0007] The adjusting buckles 1, 2, 3, and 4 mentioned above are S-shaped adjusting buckles.

[0008] Compared with the prior art, this utility model increases the wear resistance of the webbing, extends the service life of the product in harsh environments, facilitates adjustment, ensures balanced force distribution, improves user comfort, enhances the safety of the device during use, and ensures overall reliability.
