Description

Technical Field

[0001] This utility model relates to the field of rainwater trough technology, specifically a detachable rainwater trough for photovoltaic modules. Background Technology

[0002] With the increasing global demand for clean energy, photovoltaic (PV) power generation, as a clean and renewable energy source, has been widely applied and rapidly developed. As the core component of a PV power generation system, the performance and reliability of PV modules directly affect power generation efficiency and system stability. In the practical application of PV modules, rainwater drainage and treatment are crucial issues.

[0003] The prior art discloses a rainwater trough for photovoltaic modules, with publication number CN215580983U. This rainwater trough includes a photovoltaic support frame with an installation area for mounting the photovoltaic modules. The photovoltaic support frame has multiple collection slots for collecting rainwater from the surface of the photovoltaic modules in the installation area. A confluence channel communicates with the multiple collection slots to collect and discharge the rainwater from the collection slots. A baffle is positioned between the confluence channel and the installation area. Rainwater flows from the collection slots to the confluence channel, impacting the wall of the confluence channel and rebounding to the baffle. The baffle prevents rainwater splashed from impacting the confluence channel from entering the space between the confluence channel and the installation area, thus preventing water seepage into the photovoltaic modules, preventing short circuits, and avoiding disruption to the normal operation of the photovoltaic modules due to short circuits.

[0004] The aforementioned removable rainwater trough for photovoltaic modules collects rainwater from the surface of the photovoltaic modules in the installation area through a collection trough, and guides the rainwater into a confluence trough. It uses baffles to prevent rainwater from entering the gap between the confluence trough and the installation area. However, the filter inside the removable rainwater trough does not have an adjustable removal component, so it cannot effectively filter out leaves, dust and debris in the rainwater. Its performance is not good during use and needs to be improved. Utility Model Content
