Energy storage device of near-zero energy consumption building community

Abstract

The invention discloses an energy storage device of a near-zero energy consumption building community. The energy storage device comprises a solar water heater, photovoltaic panels, heat storage units, an electricity storage unit and a focusing mirror, wherein a water storage tank is fixed to the top of the solar water heater, a plurality of vacuum heat collection pipes circularly communicating with the water storage tank are arranged below the water storage tank, the photovoltaic panels are fixed in back spaces of the vacuum heat collection pipes and are connected to a power storage unit through a conversion circuits; the water storage tank is connected to the plurality of heat storage units through a water inlet channel and a water outlet channel so that hot water can be provided for theplurality of heat storage units through the solar water heater; the solar water heater is further connected to the focusing mirror in an angle-adjustable mode through an angle adjusting assembly; andduring energy storage, when light is irradiated on the vacuum heat collection pipes, the focusing mirror moves to a position where light can be provided for the photovoltaic panels, and when light isirradiated on the photovoltaic panels, the focusing mirror moves to a position where light can be provided for the vacuum heat collection pipes.

Description

technical field [0001] The invention relates to the technical field of energy storage devices, in particular to an energy storage device for a near-zero energy consumption building community. Background technique [0002] At present, many communities are equipped with energy storage devices, and the energy storage devices are mostly solar thermal storage devices. In the heating season, using solar thermal storage devices to replace the use of coal can effectively improve air quality and reduce less accidents. [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 guarante...
