Pivotable Cross-Canal Solar Array Support for Maintenance Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photovoltaic array mounting structures over canals are complex, difficult to install, and fixed in location and orientation, lacking flexibility and ease of maintenance access, which complicates canal maintenance and debris removal.
Innovation Solution
A pivotable and removable support structure for photovoltaic arrays that spans a space like a canal, featuring a major frame with hinged and disconnectable connections, allowing adjustable angles and easy disassembly for maintenance access, using structural steel components for rigidity and strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If existing photovoltaic array mounting structures are used over canals, then the arrays can be installed and provide electricity generation, but the structures become complex, difficult to install, and fixed in location and orientation
Solution Approach 1:
The support structure is divided into multiple independent modules, each comprising legs, cross members, and photovoltaic panel assemblies. These modular units can be independently manufactured, transported, and assembled on-site, reducing overall structural complexity while maintaining electricity generation capability across the canal span.
Solution Approach 2:
The structure incorporates adjustable and removable connections between modules, allowing the configuration to be dynamically changed. Connectors enable panels to be tilted or repositioned, and entire modules can be disassembled and reconfigured, transforming the fixed complex structure into a dynamic adaptable system.
2Stability of the object's composition
If existing fixed mounting structures are used, then the arrays remain stable, but access to the canal for maintenance and debris removal becomes difficult
Solution Approach 1:
The canal-spanning structure is segmented into discrete removable modules rather than a continuous fixed framework. This segmentation allows maintenance personnel to remove specific modules or sections to access the canal below, while remaining modules maintain structural stability and continue to provide shade and electricity generation.
Solution Approach 2:
The design enables temporary removal of structure components during maintenance operations. Modules can be disconnected from their anchorages and set aside, allowing unobstructed access to the canal for debris removal and maintenance activities, then reinstalled to restore the protective coverage.
3Power
If traditional mounting structures are installed, then the photovoltaic arrays can generate power, but specialized contractors are required for installation and maintenance
Solution Approach 1:
The support structure employs standardized modular components with simplified connection mechanisms that can be assembled using basic tools and techniques. This modular approach enables local contractors or even trained volunteers to install and maintain the structure without requiring specialized heavy equipment or highly skilled technicians, while still achieving the necessary structural integrity for power generation.

AI summary
A cross canal support structure for photovoltaic cells is disclosed. The structure includes a major frame having disconnectable and hinged connections to anchors at its corners, on either side of the canal. The major frame carries a plurality of minor frames, which are inclinable at an angle with respect to the major frame with the use of fixed or adjustable mounting plates. The combination of the major frame's tilt and the minor frame tilt enables fabrication of support structures that hold panels at latitude inclination for various portions of a canal.
