Worm-Gear Self-Locking for Photovoltaic Panel Cleaning Mobility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional photovoltaic panel cleaning equipment lacks a self-locking mechanism, causing the equipment to easily fall off photovoltaic panels with gradients, which affects cleaning efficiency and safety.
Innovation Solution
A self-locking mechanism is integrated into the moving mechanism of the cleaning equipment, utilizing worm gears and worms to enable self-locking of driving wheels, ensuring the equipment can move steadily and stop securely on photovoltaic panels, preventing falls due to gravity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional moving mechanism without self-locking is used, then device complexity is reduced, but reliability deteriorates due to equipment falling off photovoltaic panels with gradients
Solution Approach 1:
The worm gear mechanism automatically locks the driving wheel when the motor stops, without requiring external locking devices or additional control systems. The self-locking function is inherent in the worm gear structure itself, where the worm can drive the worm gear but the worm gear cannot reverse-drive the worm, providing automatic position holding capability.
Solution Approach 2:
The worm gear acts as an intermediary mechanism between the driving motor and the driving wheel. It transmits motion from the motor to the wheel while simultaneously providing the self-locking function, serving both motion transmission and position fixation purposes through a single intermediate component.
2Reliability
If self-locking mechanism with worm gear is added, then reliability is improved by preventing falls, but device complexity increases due to additional components
Solution Approach 1:
The worm gear mechanism performs multiple functions simultaneously: it transmits rotational motion from the driving motor to the driving wheel, and it provides self-locking capability to prevent the equipment from falling off gradient panels. This multi-functionality reduces the need for separate locking devices.
Solution Approach 2:
The worm gear structure inherently provides self-locking without requiring additional locking components or external power sources. The geometric relationship between the worm and worm gear teeth creates automatic engagement that holds position when motion stops, making the system self-sufficient for both motion and positioning.
3Productivity
If conventional driving mechanism is used, then ease of operation is maintained, but productivity deteriorates due to inability to maintain constant speed on gradients
Solution Approach 1:
The worm gear self-locking mechanism automatically maintains driving wheel position and prevents slipping on gradient panels without requiring active control intervention. This allows the cleaning equipment to maintain steady motion and constant cleaning speed on inclined surfaces, improving productivity without adding complex control systems.

AI summary
A self-locking mechanism which is mounted in a moving mechanism of a photovoltaic panel cleaning equipment is disclosed. The moving mechanism includes driving wheels driven by driving motors, and the driving wheels being diagonally and detachably mounted. The self-locking mechanism includes self-locking units arranged between the driving motor and the driving wheel of the moving mechanism, and is used for realizing self-locking of the respective driving wheel. By adopting the self-locking mechanism and the photovoltaic panel cleaning equipment having the self-locking mechanism, when the body of the photovoltaic panel cleaning equipment stops on the photovoltaic panel with a gradient, the body can be prevented from falling off due to the effect of gravity.
