Wind Turbine Blade Protective Layer Booth Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The formation of protective layers on wind turbine blades leads to dust scattering, necessitating a large booth to contain the blades, which in turn increases the size of the protective layer forming device.
Innovation Solution
A protective layer forming device that includes a booth surrounding a part of the wind turbine blade, a spray unit inside the booth, and mechanisms for moving the spray unit and booth along the blade length direction to form the protective layer, reducing the device's overall size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a large booth is used to surround the entire wind turbine blade to suppress dust scattering, then dust scattering is suppressed, but the device size increases
Solution Approach 1:
The patent divides the blade treatment into multiple sections by processing the leading edge portion separately from other areas. The booth only needs to surround the leading edge portion (a segment of the blade) rather than the entire blade, thus suppressing dust scattering locally while keeping the booth size compact.
Solution Approach 2:
The invention applies protective layer formation selectively to the leading edge portion where erosion resistance is most critical, rather than treating the entire blade uniformly. This localized approach allows the booth to be sized appropriately for just the critical area, reducing overall device size while still achieving the necessary protective function where needed most.
2Area of stationary object
If a compact booth is used to reduce device size, then device size is reduced, but dust scattering control becomes difficult
Solution Approach 1:
By segmenting the treatment area to focus only on the leading edge portion, the patent enables effective dust control within a compact booth. The spray unit can be positioned and operated optimally within the smaller space since it only needs to cover the leading edge area, maintaining dust scattering control despite the reduced booth size.
Solution Approach 2:
The spray unit acts as an intermediary element that enables effective protective layer formation within the compact booth. By positioning the spray unit strategically within the limited space and using it to deliver the protective material precisely to the leading edge, the system achieves both compact size and effective dust control.
3Manufacturing precision
If the spray unit is positioned optimally for thermal spraying, then protective layer quality is improved, but device complexity increases
Solution Approach 1:
The patent employs a movable spray unit that can be dynamically positioned and adjusted during the protective layer formation process. This dynamic positioning capability allows the spray unit to maintain optimal distance and angle relative to the leading edge portion throughout operation, ensuring high protective layer quality while the booth itself remains compact.
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 device effectively suppresses dust scattering and allows precise spraying without enlarging the booth, thereby reducing the device's size and improving the quality of the protective layer on the wind turbine blade.

AI summary
The purpose of the present invention is to reduce the overall size of a protective layer forming device. A protective layer forming device (100) forms a protective layer in an application range of a front edge portion, at the leading end in the blade-length direction, of a windmill blade body (5a) formed of FRP. The protective layer forming device (100) comprises: a booth (140) that surrounds a part, in the blade-length direction, in the application range of the windmill blade body (5a); a spray unit that is provided inside the booth (140) and that sprays an application material to the application range to form the protective layer; a multi-joint robot that moves the spray unit relative to the booth (140) and moves the spray unit to a prescribed position where spraying is performed with respect to the application range of the windmill blade body (5a); and a booth moving mechanism that moves the booth (140) in the blade-length direction of the windmill blade body (5a).
