AI Technical Summary
Traditional photovoltaic roofs require additional drainage structures, have poor sealing, are prone to leakage, lack wind pressure resistance, are complex to install, and are difficult to balance airtightness, heat insulation, and drainage at the same time.
An integrated drainage photovoltaic roof support structure was designed, integrating longitudinal and transverse water channels on the bracket. The color steel tiles are fixed by mechanical seals, and the support and pressure block components improve installation stability. The column design enhances wind pressure resistance, and the purlins and beams form a self-locking structure. Integrated baffles improve air tightness.
No additional drainage structure is required, reducing the risk of leakage, lowering costs, improving installation efficiency, enhancing wind pressure resistance, improving sealing and insulation, and simplifying the construction process.

Abstract
Claims
1. An integrated drainage photovoltaic roof support structure, characterized by: The system includes a bracket, a support for installing photovoltaic modules, and a pressure block. The bracket includes a horizontal beam arranged sequentially at the top, columns supported at both ends of the horizontal beam, and purlins fixed between the horizontal beams and arranged sequentially along the length of the horizontal beam. The ends of the purlins overlap the horizontal beams. The purlins have longitudinal water grooves along their length, and the horizontal beams have transverse water grooves along their length. Each side of the purlin has an inwardly extending limiting edge, thus forming a concave portion on the inner side of each side of the purlin. Each side of the corrugated steel sheet has a side connecting portion that can fit into the concave portion. The lower part of the support is inserted into the longitudinal water groove of the purlin, and the side connecting portion of the corrugated steel sheet is locked to the inner side of the purlin through the support. The pressure block is installed on the support and has a pressure plate for pressing on the photovoltaic modules.
2. The integrated drainage photovoltaic roof support structure of claim 1, wherein: The support has outwardly extending shoulders located inside the purlins on both sides. A support base plate is provided below the support, and a threaded limiting hole is provided on the support base plate. A limiting bolt is threaded into the threaded limiting hole. The side connecting part is located below the limiting edge. By the limiting bolt abutting against the bottom surface of the longitudinal water tank, the shoulders can press the side connecting part against the limiting edge from the top.
3. The integrated drainage photovoltaic roof support structure of claim 2, wherein: The photovoltaic roof support structure also includes a first clamping plate assembly. The support has a first connecting edge on its upper part. The first clamping plate assembly is clamped on the first connecting edge, and the pressure block is connected to the first clamping plate assembly.
4. The integrated drainage photovoltaic roof support structure of claim 3, wherein: The first clamping plate assembly is provided with a waist hole, and the pressure block is provided with a vertical connecting hole. A pressure block connecting bolt passes through the connecting hole and the waist hole and is connected to the pressure block connecting nut to achieve connection.
5. The integrated drainage photovoltaic rooftop support structure of claim 1, wherein: The columns include valley columns, middle columns, and peak columns with progressively increasing heights. The valley columns, middle columns, and peak columns on the same side are arranged alternately, and the columns on the side corresponding to the ridge are higher than the columns on other sides.
6. The integrated drainage photovoltaic rooftop support structure of claim 1, wherein: The photovoltaic roof support structure also includes a second clamping plate assembly. A second connecting edge is provided on the top of the crossbeam. The end of the purlin rests on the top of the second connecting edge. The second clamping plate assembly fixes the end of the purlin to the second connecting edge together.
7. The integrated drainage photovoltaic rooftop support structure of claim 1, wherein: The color steel tile includes a metal plate and an insulation layer disposed on the inner side of the metal plate. The side connecting part is formed by bending the two sides of the metal plate. The side connecting part forms a groove corresponding to the position of the limiting edge, and forms a protrusion corresponding to the position of the concave part.
8. The integrated drainage photovoltaic rooftop support structure of claim 1, wherein: The thickness of the eaves plate near the far edge of the photovoltaic module gradually decreases from the inside to the outside.
9. The integrated drainage photovoltaic rooftop support structure of claim 1, wherein: The photovoltaic roof support structure also includes a baffle, which is fixedly installed between the crossbeam and the corrugated steel sheet.
