Description

Waterproof overlap joint type solar photovoltaic module
Technical Field
The invention relates to a waterproof lap joint type solar photovoltaic module, and belongs to the technical field of solar energy.
Background
With the continuous exploitation and consumption of non-renewable energy sources such as petroleum and coal, the use of renewable energy sources such as solar energy is more popular in various places. The solar photovoltaic modules at the current stage are firstly arranged on a building roof and then fixed on the support for use, the solar photovoltaic modules with external frames are arranged and placed one by one at certain intervals longitudinally and transversely according to the area of the building roof, and then the solar photovoltaic modules are respectively fixed on the support until the required solar photovoltaic quantity is always installed.
However, as solar energy is increasingly used in buildings, in order to reduce material and installation cost, people combine solar photovoltaic modules with building roofs to form a solar photovoltaic building integrated structure, namely, a plurality of solar photovoltaic modules are spliced together and can be used as the roofs while being converted into electric energy or other energy sources, so that the problem of water resistance needs to be considered, waterproof glue is filled into a lower gap between each solar photovoltaic module to be plugged with foam, then the waterproof glue is filled into a gap above the foam, and the waterproof glue is filled in the gap because the foam filled with the waterproof glue is high or low, so that the sealing is not firm due to the fact that the amount of glue used in the slightly high place is small, and the waterproof effect is reduced; the lower glue consumption is more, so that the unnecessary waste of the waterproof glue is caused, and the material cost is greatly increased; and the foam of the plug between adjacent solar photovoltaic modules is supported by no other structure, so that the risk that the foam falls off from the roof exists.
In the patent solar photovoltaic module lap joint type splicing sealing structure (CN 205029618U), an upper lap joint block and a lower lap joint block which are arranged on the outer walls of corresponding frame profiles of adjacent solar photovoltaic modules are mutually staggered to splice, in the process of discharging the solar photovoltaic modules transversely and longitudinally one by one, the upper lap joint blocks and the lower lap joint blocks on the adjacent solar photovoltaic modules are not required to be staggered and butted together in a contact manner, enough gaps are reserved between the longitudinal directions, after splicing is completed, waterproof glue is filled between the gaps at the upper ends of the lap joint blocks on the adjacent two solar photovoltaic modules, and each solar photovoltaic module is connected together in a sealing manner, so that the solar photovoltaic modules are built into a solar photovoltaic building integrated roof, and the effects of power generation and water prevention are achieved. However, the use amount of the waterproof adhesive cannot be well controlled due to the fluidity and the viscosity of the waterproof adhesive, and the waterproof effect is reduced due to the fact that the sealing is not firm due to the fact that the use amount of the waterproof adhesive is small; the water-proof glue is unnecessarily wasted due to the fact that the glue is used in a large amount, and the material cost is increased.
