An energy storage device for a near-zero energy building community

Abstract

The invention discloses an energy storage device for a near-zero-energy building community, which includes a solar water heater, a photovoltaic panel, a heat storage unit, an electricity storage unit, and a focusing mirror, wherein a water storage tank is fixed on the top of the solar water heater, and the The bottom of the water storage tank is provided with a plurality of sets of vacuum heat collecting tubes which are circulated in communication with it, and the back space of the vacuum heat collecting tubes is fixed with a photovoltaic panel, and the photovoltaic panel is connected with the power storage unit through a conversion circuit; The water channel and the water outlet channel are respectively connected to multiple sets of heat storage units, so as to provide hot water for multiple sets of heat storage units through the solar water heater; the solar water heater also uses an angle adjustment component to adjust the angle and is connected with a focusing mirror; And when storing energy, when the light shines on the vacuum heat collecting tube, the focusing lens moves to a position that can provide light for the photovoltaic panel, and when the light shines on the photovoltaic panel, the focusing lens moves to a position that can provide light for the vacuum collector. Where the heat pipe provides light.

Description

An energy storage device for a near-zero energy building community technical field [0001] The present invention relates to the technical field of energy storage devices, in particular to an energy storage device in a near-zero energy consumption building community. Background technique [0002] At present, many communities are provided with energy storage devices, and the energy storage devices are mostly solar heat storage devices. In warm seasons, the use of solar thermal storage devices to replace the use of coal can effectively improve air quality and be less safe the occurrence of the accident. [0003] However, the existing energy storage device has a single energy storage method, which can only use solar energy to store thermal energy, and Due to the large size of the device, it is inconvenient to move, and it cannot be changed correspondingly with the change of the angle of illumination, so that the whole The collection efficiency of the body is low. Fortunatel...

[0003] However, the existing energy storage device has a single energy storage method, which can only use solar energy to store heat energy, and because the device is large in size and inconvenient to move, it cannot change correspondingly with the change of the angle of illumination, making the overall The collection efficiency is low, but fortunately, the amount of hot water required for heat storage is not large, so the temperature of the hot water can be guaranteed. In case of insufficient water
