BIPV(Building Integrated Photovoltaic) roof of heat radiating type double-layer waterproof structure

Abstract

The invention discloses a BIPV(Building Integrated Photovoltaic) roof of a heat radiating type double-layer waterproof structure, comprising a solar photovoltaic component, main water gutters, secondary water gutters, shock absorbing pressing blocks, component pressing blocks, a ground strap, a shock absorbing pad, waterproof covers, a heat radiating chamber and a ventilating window, wherein the main water gutters are longitudinally fixed on two sides of the solar photovoltaic component through the component pressing blocks and shock absorbing pressing blocks, support bases on two sides of the main water gutters are fixed to purlines on the roof through tapping screws, the secondary water gutters are in lap joint on the main water gutters in a direction vertical to the main water gutters and are provided with articulation structures through which the secondary water gutters are fixed to the solar photovoltaic component, the component pressing blocks are covered with the waterproof covers, heat below the solar photovoltaic component can be radiated through a clearance between the waterproof covers and the solar photovoltaic component, the heat radiating chamber is arranged below the solar photovoltaic component, and the ventilating window is arranged on the heat radiating chamber.

Description

technical field [0001] The invention relates to the field of solar power generation, in particular to photovoltaic building integrated roofs. Background technique [0002] BIPV is BuildingIntegratedPV is photovoltaic building integration. PV is Photovoltaic. BIPV technology is a technology that integrates solar power generation (photovoltaic) products into buildings. Photovoltaic building-integrated (BIPV) is different from the form of photovoltaic system attached to the building (BAPV: BuildingAttachedPV). In modern society, people's pursuit of a comfortable building environment is getting higher and higher, which leads to the increasing energy consumption of building heating and air conditioning. In developed countries, building energy consumption has accounted for 30%-40% of the country's total energy consumption, which has formed a certain restrictive effect on economic development. The emergence of photovoltaic building integration effectively uses renewable energy t...

Problems solved by technology

[0014] It can be seen from the above literature that the waterproofing of photovoltaic roofs is one of the technical difficulties that personnel in this field currently specialize in. Solar photovoltaic modules are usually fixed on the roof by splicing. Problems such as water leakage and long-term water immersion and corrosion of components are particularly prominent

Under normal circumstances, both sides of the solar photovoltaic module will divert the accumulated water on the roof through the water tank, but the general single-layer waterproof structure cannot meet the waterproof requirements, and most solar roofs are fixed on the module frame with self-tapping screws. Long-term wind and rain
