AI Technical Summary

Technical Problem

Existing photovoltaic power generation arrays are prone to water leakage when it rains, especially the bottom photovoltaic panels which are severely damaged, and they cannot be adjusted according to the width of the photovoltaic panels, resulting in poor applicability.

Method used

It adopts a longitudinal sealing mechanism and a secondary water inlet design. The longitudinal sealing seat seals the gap between adjacent photovoltaic panels, the secondary water inlet collects rainwater and discharges it through the drainage channel. Combined with the movable connection component, the position of the support rod can be adjusted to accommodate photovoltaic panels of different widths.

Benefits of technology

It effectively prevents rainwater leakage, reduces rainwater flow on the surface of photovoltaic panels, enhances sealing, has strong applicability, avoids damage to photovoltaic panels, and is suitable for installation of photovoltaic panels of different widths.

Abstract

This invention provides a leak-proof photovoltaic power generation array and its installation method, including mounting legs, connecting hinges, horizontal support rods, vertical support rods, movable connecting components, support frames, photovoltaic panels, vertical sealing seats, vertical sealing mechanisms, secondary water receiving channels, drainage channels, and connecting water pipes. Each row of photovoltaic panels in this invention has a secondary water receiving channel at its bottom, and all secondary water receiving channels are connected to the drainage channel. Since rainwater from each row of photovoltaic panels is collected and discharged through the corresponding secondary water receiving channel, the rainwater flow rate on the surface of each row of photovoltaic panels is the same during rain, preventing rainwater accumulation. The gaps between adjacent photovoltaic panels in the same row are sealed by the vertical sealing mechanism, enhancing the sealing performance and ensuring that rainwater can only flow downwards into the secondary water receiving channels. Because the movable connecting components are detachably fixed to the horizontal support rods, the positions of the vertical support rods and vertical sealing seats can be adjusted according to the width of the photovoltaic panels.
