Building roof heat insulation device

Abstract

The invention discloses a building roof heat insulation device. The building roof heat insulation device comprises an upper heat insulation plate, a lower heat insulation plate and baffles and is characterized in that a solar electric plate is mounted on the upper heat insulation plate, a square through hole is formed in the center of the upper heat insulation plate, and an electric fan and a storage battery are mounted in the middle of the lower heat insulation plate; and the solar electric plate is in electric connection with the electric fan and the storage battery through wires, the baffles are arranged between the upper heat insulation plate and the lower heat insulation plate, the upper heat insulation plate and the lower heat insulation plate are fixedly connected with the baffles through a supporting frame, and a recessed cavity is formed between the upper heat insulation plate and the lower heat insulation plate. The building roof heat insulation device has the beneficial effects that the structure is simple, the device is not limited by specific materials, the number of energy conversation times is few, external convection conditions are not relied on, and universal adaptability is achieved for roofs of various types; by converting solar energy into electric energy, stable power is provided for heat convection, and other energy does not need to be consumed; and the higher the temperature is, the more the provided energy is, and the better the heat insulation effect is.

Description

technical field [0001] The invention relates to the field of building structures, in particular to a building roof heat insulation device. Background technique [0002] At present, the roof tiles commonly used in construction engineering units cannot play a role in heat insulation. In summer, due to the hot sun, the temperature will rise, especially for residents living in high-rise buildings, the house will be unbearably hot. Now the roof temperature is about 40 degrees Celsius, and the traditional way cannot solve the problem of effective heat insulation. At present, some heat insulation methods mainly include: convection plate heat insulation, material heat insulation, plant planting method heat insulation and water circulation heat insulation. In addition to water circulation insulation, other insulation methods are not ideal. Although the heat insulation of the convection plate can block the heat transfer in theory, in practical application, it relies too much on the ...

Problems solved by technology

Although the effect of water circulation heat insulation is better, it consumes a lot of energy and is limited to the structural conditions of the building. General houses are not suitable for promotion.

Planting plants on the roof is first to take and use the cultivation soil and the planted
