Description

TECHNICAL FIELD

[0001] The utility model belongs to photovoltaic equipment, concretely relates to a novel roof BIPV photovoltaic device adopting U-shaped water collecting groove. BACKGROUND

[0002] The building roof resources in China are rich, widely distributed, and have huge distributed photovoltaic potential. Carrying out roof distributed photovoltaic construction in the whole county (city, district) is conducive to integrating resources and realizing intensive development, conducive to reducing power peak load, conducive to saving and optimizing power distribution network investment, and conducive to guiding residents to consume green energy.

[0003] The roof BIPV photovoltaic U-shaped water collecting groove structure is mainly suitable for collecting rainwater of a concrete roof BIPV photovoltaic module.

[0004] In the design process of BIPV, a two-layer waterproof solution is usually adopted to ensure the waterproof level of the roof. The first layer of waterproof is designed by using an integrated cover strip in combination with a foamed silica gel strip. The integrated cover strip is completely attached to the module frame to avoid dirt, leaves and other sundries from entering the main water groove, and at the same time, the amount of rainwater entering the main water groove is minimized. The foamed silica gel strip is used to fill the gap between the modules to maximize the prevention of water from entering the horizontal water groove. Even in a stormy weather, the amount of water entering the main water groove and the horizontal water groove is very small, and 99% of the rainwater flows to the gutter through the surface of the module. The main water groove and the horizontal water groove structure support the module, which plays a second layer of waterproof effect. 1% of the seepage water enters the main water groove and the horizontal water groove, and then flows to the gutter through the main water groove. The main water groove is usually a certain distance away from the gutter. If the water in the main water groove directly flows to the gutter, it will cause rainwater to drain to the roof, which cannot achieve the waterproof effect of the roof. Especially when the original roof waterproof level is not enough, the roof will leak seriously, causing safety hazards.

[0005] Therefore, for roofs with strict waterproof requirements, in order to avoid roof rainwater leakage, the BIPV roof drainage structure needs to be improved. CONTENT OF THE UTILITY MODEL
