Flexible Duct Layout for Wind Blade Protective Layer Booths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The connection between a dust collection device and a booth for forming a protective layer on a wind turbine blade is prone to damage due to movement, especially when a load is applied to the connecting pipe or duct.
Innovation Solution
A protective layer formation apparatus that includes a booth surrounding a part of the wind turbine blade, a spray unit inside the booth to apply the protective layer, a booth movement mechanism, a dust collection device separate from the booth, and a flexible duct connecting the booth to the dust collection device, with support mechanisms to reduce stress and prevent damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a rigid pipe or duct is used to connect the booth to the dust collection device, then the connection is structurally stable, but the duct may be damaged when the booth moves or load is applied
Solution Approach 1:
The patent employs a flexible duct made of expandable material to connect the booth to the dust collection device. This flexible duct can expand and contract while maintaining connection integrity, preventing damage during booth movement or when load is applied, thus resolving the contradiction between connection stability and damage resistance.
2Volume of moving object
If the dust collection device is disposed outside the booth, then the booth interior space is increased, but a pipe or duct must be provided to connect the booth to the dust collection device
Solution Approach 1:
The flexible duct serves as a compact connection solution that allows the dust collection device to be positioned outside the booth while maintaining a relatively simple overall structure. The expandable nature of the duct accommodates movement without requiring complex rigid connection mechanisms.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus prevents damage to the duct connecting the booth and dust collection device by allowing the duct to deform and reducing stress, thus maintaining a safe and effective protective layer formation process.
Implementation Method 1
a flexible duct that connects the booth to the dust collection device
Implementation Method 2
a spray unit that is provided inside the booth and sprays a construction material to the construction range to form the protective layer
Implementation Method 3
a dust collection device that is provided to be separated from the booth and collects dust in the booth

AI summary
The purpose of the present invention is to reduce the occurrence of damage to a duct. This protective layer formation apparatus (100) is for forming a protective layer in a construction area on a front edge part of a tip section in a blade length direction of an FRP-made wind turbine blade body. The protective layer formation apparatus (100) is provided with: a booth (140) that surrounds a portion of the construction area in the blade length direction of the wind turbine blade body; a spraying unit that is disposed inside the booth (140) and forms the protective layer by spraying a construction material to the construction area; a booth moving mechanism that moves the booth (140) in the blade length direction (L1) of the wind turbine blade body; a dust collection device (160) that is disposed apart from the booth (140) and collects dust in the booth (140); and a flexible duct (161) that connects the booth (140) with the dust collection device (160).
