Power generation device attached to exterior wall of building

Abstract

The invention relates to power generation devices, in particular to a power generation device attached to an exterior wall of a building. The power generation device mainly comprises a wind gathering cover, a support, a wall-attached air tube, an air tube heat-absorbing surface, an impeller and a power generator. The power generation device is mainly powered by that firstly, sunlight radiation enables air in the wall-attached air tube to be heated, and air density becomes smaller to generate lift force; secondly, potential energy of rainfall drives the impeller to rotate to generate power; thirdly, wind at the top of a roof of the building is compressed when passing through the flared wind gathering cover, so that flow velocity is increased, negative pressure is generated and flow velocity of the wind in the wall-attached air tube is increased. The power generation device attached to the exterior wall of the building converts energy from natural air convection, air convection forced by sunshine heating and rainfall downflow potential energy so as to generate powder whether in windy days, rainy days or sunny days. The power generation device attached to the exterior wall of the building has the advantages of good power generation effect, cleanness and no pollution.

Description

technical field [0001] The invention relates to a power generating device, in particular to a power generating device attached to the outer wall of a building. Background technique [0002] my country has abundant wind resources on land. The total amount of wind energy at a height of 10m is 3.2 billion kilowatts, of which the total amount of wind energy that can actually be developed at a height of 50m on land is 800 million kilowatts. The entire eastern part of China is a typical monsoon air outlet, where winter monsoon prevails in winter, summer monsoon prevails in summer, and spring and autumn are also windy. In the eastern region, the wind speed on the walls of high-rise buildings is much higher than that on the ground. In order to utilize this part of wind energy, the invention patent with the patent number of 200810023175.9 provides a method of wind power generation on the exterior wall of a building, which uses the wind energy naturally existing in the space of the e...

Problems solved by technology

[0003] The exterior walls of buildings are exposed to solar radiation, and solar panels can also be installed to generate electricity. However, at present, the cost of solar panels is too high, and it is still difficult to promote them on a large scale.
