Generator Protective Cover Structure for Safe Running Operation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional protective covers for generators cannot be used when the generator is running, as they lack a frame, making them inconvenient for use and exposing the generator to dust and potential hazards in humid environments.
Innovation Solution
A protective cover with a main body, frame, and top cover, featuring rollable side wings and a stainless steel frame that can be fixed to the generator, allowing for use during operation, with a flat top cover design to reduce wind resistance and facilitate fuel addition.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional protective covers without frame are used, then the structure is simple and easy to manufacture, but the generator cannot be used in running state and operators are exposed to electric shock hazards
Solution Approach 1:
The protective cover uses a flexible cloth material for the main body and side wings, combined with a detachable frame structure. The frame can be assembled or disassembled based on operational needs, providing safety protection when required while maintaining simplicity when not in use. This resolves the contradiction by making the protective structure adaptable rather than permanently complex.
Solution Approach 2:
The protective cover is divided into multiple detachable components: the main body, side wings, and frame segments. The frame itself is segmented into multiple parts that can be assembled together. This segmentation allows the structure to be simple during storage and transport, but provides complete safety protection when assembled and in use, resolving the contradiction between simplicity and safety.
2Reliability
If fan-shaped protective covers with fixed top cover are used, then the generator is protected during running, but fuel addition and maintenance operations become very inconvenient
Solution Approach 1:
The top cover is designed to be detachable rather than fixed, allowing it to be removed or opened when fuel addition or maintenance is needed. This dynamic design enables the protective cover to provide full protection during normal operation while allowing easy access when required, resolving the contradiction between protection and operational convenience.
Solution Approach 2:
The side wings are designed to be rollable and can be preliminarily adjusted to different positions. When fuel addition is needed, the side wings can be rolled up in advance to facilitate access, while still maintaining protection when in the unfolded position. This preliminary adjustability resolves the contradiction by allowing the structure to be optimized for different operational states.
3Reliability
If raised fan-shaped top cover is used, then the generator is well protected, but wind resistance is significantly increased
Solution Approach 1:
The top cover is designed with a curved, aerodynamic shape rather than a raised fan-shaped structure. This curvature reduces wind resistance by allowing wind to flow smoothly over the cover, while still providing adequate protection coverage for the generator. The curved design resolves the contradiction between protection and wind resistance by optimizing the shape for aerodynamic performance.
4Object-affected harmful factors
If side wings are fixed in unfolded position, then generator is protected from dust, but the cover cannot be used for running generators and ventilation is poor
Solution Approach 1:
The side wings are designed to be rollable and adjustable, allowing them to be in the unfolded position for dust protection during storage or non-operational states, and rolled up when the generator needs to run. This dynamic adjustability resolves the contradiction by allowing the same structure to serve different functions based on operational requirements.

AI summary
A protective cover for a generator in a running state includes a main body, a frame, and a top cover. The main body includes side wings capable of being rolled up and unfolded down. The side wings are enclosed to define an accommodating cavity. The accommodating cavity defines an upper opening and a lower opening and is matched with the generator. The frame is arranged in the accommodating cavity and is fixedly connected with the generator. The frame is fixed with the side wings. The top cover is openable and arranged on a top portion of the main body and covers the upper opening on an upper end of the accommodating cavity. When the generator is in the running state, the protective cover is used through the frame. Especially in a humid environment, the protective cover protects the generator from short circuit and protects an operator from electric shock.
