Assembly system of drainage component

Abstract

The invention discloses an assembly system of a drainage component, which comprises a drainage component water guide layer and a drainage component water diversion layer. The upper part of a frame of a photovoltaic assembly is a surface A, the side part of the frame is a surface B, and the lower part of the frame is a surface C. The drainage component water guide layer is arranged on the outer side of the surface A, and the drainage component water diversion layer is arranged on the outer side of the surface B and is spaced from the surface B by a certain distance. A hole with threads is preset in the surface B of the frame, an adjusting bolt screwed into the hole is arranged on the drainage component water diversion layer in a penetrating mode, and the threads of the hole correspond to the threads of the adjusting bolt. A supporting object is arranged between the drainage component water diversion layer and the hole, the supporting object is made of an elastic material with the telescopic thickness, and the thickness of the supporting object is adjusted through rotation of the adjusting bolt. The system is low in cost, easy to operate, good in flow guide effect, adjustable and not prone to blockage after being used for a long time. Raw materials are saved and cost is reduced. The risks of loosening and falling of conventional drainage components after wind load and snow load are avoided. The drainage channel is prevented from being blocked.

Description

technical field [0001] The invention relates to the technical field of photovoltaic components, in particular to a component system of drainage components. Background technique [0002] Photovoltaic modules are generally fixed by an aluminum alloy frame for outdoor installation. In order to ensure that the module can withstand the load and pressure brought by the storm and snow, the module glass must be wrapped in the frame, that is, the height of the side edge of the frame is significantly higher than the glass surface, which will As a result, dust is easy to accumulate at the corners, especially in scenarios where components are installed with low inclination angles such as distributed roofs. The dust accumulated on the edges of the components has been subjected to rain, snow, exposure, etc. for a long time to form silt and only stick to the glass surface. The inner side of the frame is generally controlled within 15mm, and the silt on the glass surface will accumulate mor...

Problems solved by technology

[0005] However, there is an obvious problem with this design that the service life is short. On the one hand, the force between the upper and lower buckles and the frame is small, and there is a risk of loosening and falling off after long-term outdoor wind and snow loads; on the other hand, the fastened buckle The pendant is closely attached to the B side of the frame, and only the corrugated tile groove on the side can be used for drainage and dust removal. Once a large amount of dust with large particle size accumulates outdoors, it is easy to block the diversion channel, resulting in failure of drainage and dust removal
