A system of components for drainage components

Abstract

The invention discloses an assembly system of a drainage member, comprising a water-conducting layer of a drainage member and a water-guiding layer of a drainage member. The upper part of the frame of the photovoltaic module is the A surface, the side part of the frame is the B surface, and the lower part of the frame is the C surface. The water-conducting layer of the drainage member is arranged on the outer side of the A surface, the drainage member water-conducting layer is arranged on the outer side of the B-face and has a certain distance from the B-side, the B-side of the frame is preset with threaded holes, and the drainage member water-guiding layer is provided. There is an adjusting bolt screwed into the hole, and the thread of the hole corresponds to the thread of the adjusting bolt; a support is arranged between the water diversion layer of the drainage member and the hole, and the support is made of elastic and retractable thickness. The thickness of the object is adjusted by the rotation of the adjusting bolt. The invention has the advantages of low cost, simple operation, good diversion effect, adjustable and long-term use, and is not easy to block; saves raw materials and reduces costs; avoids the risk of loosening and falling off of conventional drainage components after wind and snow loads;

Description

technical field [0001] The present invention relates to the technical field of photovoltaic components, in particular to a component system of a drainage component. Background technique [0002] Photovoltaic modules are generally fixed by an aluminum alloy outer frame to facilitate outdoor installation. In order to ensure that the modules can withstand the load pressure caused by strong storms and snow, the module glass needs to 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 in the corners, especially in the scenarios where the modules are installed with a low inclination angle such as distributed roofs. The dust on the edges of the modules is affected by rain, snow, and exposure to the sun for a long time to form silts and only stick to the glass surface. The inside of the frame is generally controlled within 15mm, and the silt on the glass surface ...

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
