Description

Adjustable photovoltaic waterproof bracket clamp for trapezoid color steel tile roof and mounting method of clamp Technical Field The invention belongs to the field of photovoltaic assembly installation facilities, and particularly relates to an adjustable photovoltaic waterproof bracket clamp for a trapezoid color steel tile roof and an installation method thereof. Background With the transformation of global energy structures and the enhancement of environmental protection consciousness, solar photovoltaic power generation has been widely focused and applied on a large scale worldwide as a clean and renewable green energy source. In various installation scenes of photovoltaic power generation systems, it has become a mainstream trend to construct distributed photovoltaic power stations by using roofs of buildings such as industrial plants, warehouses and the like. The trapezoid color steel tile roof has the advantages of low cost, convenience in construction, stable structure and the like, and occupies a great market share in industrial buildings. However, to stably, safely and permanently mount photovoltaic modules on such roofing, the design and performance of the photovoltaic bracket fixture plays a vital role. In the prior art system, in order to fix the photovoltaic module guide rail on the trapezoid color steel tile, a special connecting fixture is generally required. Early clamps were mostly of a fixed size design, and this one-to-one mode exposed a significant limitation in the face of a wide variety of color steel tile specifications. The width, the height and the slope angle of the side face of the wave crest of the trapezoid color steel tile are different from each other in different manufacturers and different bearing requirements. If the size of the clamp is not matched with the wave crest of the color steel tile, not only installation difficulty can be caused, but also structural deformation caused by uneven stress can be generated, even the roof coating of the color steel tile is damaged, the service life of the roof is shortened, and leakage risk is caused. In order to solve the problem of poor commonality, some adjustable photovoltaic supporting structure appears in the trade, tries to adapt to the tile of equidimension through the mode of mechanical slip, through sliding connection between mount and extension board, can carry out horizontal extension or shorten according to the width of various steel tile top surface, and the connecting plate then adapts to the slope of side through articulated mode. Although the design improves the adaptation effect of the device to different sizes of color steel tiles to a certain extent, the technical scheme still has obvious limitations from the aspects of actual construction and long-acting operation. The existing adjusting type clamp is low in adjusting efficiency, and the width adjustment of the existing adjusting type clamp is completely dependent on manual rotation. In an actual large-scale photovoltaic construction site, thousands or even tens of thousands of clamps are often required to be installed on a roof, each clamp needs to be manually and precisely adjusted according to the size measured on site, and an adjusting bolt is rotated to enable internal clamping teeth to be meshed and fixed. The tedious operation not only consumes huge physical effort on installers, but also slows down the engineering progress more seriously. In an overhead working environment, the long-time manual fine adjustment also increases potential safety hazards. Second, the economics and durability of existing structures perform poorly in harsh outdoor environments. The clamp is exposed in the environment of sun and rain and large temperature difference fluctuation for a long time, and is extremely easy to be corroded, oxidized or fouled. Furthermore, the prior art has obvious short plates in the aspect of coping with stress generated by thermal expansion and cold contraction. The color steel tile roofing can produce severe temperature alternation between intense sunlight irradiation and cold night, thereby causing obvious material deformation. Conventional adjustable clamps, such as those employing latch locking or adjustment bolts, tend to form a highly rigid connection system. When the color steel tile is subjected to thermal expansion and cold contraction, the rigid connection cannot provide enough flexible displacement space, so that thermal stress directly acts on the fastening bolt. In the long term, the load born by the bolts can cause metal fatigue, so that the connecting part is loosened, the color steel tile hole sites are more seriously torn, the original waterproof layer is damaged, and the serious roof water leakage problem is caused. In addition, the existing scheme is single in waterproof design, surface sealing is carried out only by means of a simple gasket, the structural design for actively guiding and discharging accumulated water in the infiltra
