Large-capacity well type solar heat collection-storage device

The invention relates to the field of solar heat collection and storage technologies and discloses a high-temperature large-capacity well type solar heat collection-storage device. A primary reflector of the large-capacity well type solar heat collection-storage device is a concave mirror reflector, and a plurality of the primary reflectors are fixed on the ground to form a reflector array; a secondary reflector is mounted in the air and is a convex mirror reflector which is opposite to the primary reflectors, a conical solar well is arranged below the secondary reflector, and a heat absorbing body is arranged at the bottom of the solar well; a heat storage tank body is a hollow tank body, the middle of the heat storage tank body is the solar well, a part of the heat storage tank body is buried underground and is filled with a heat storage medium; a hot air pipe and a cold air pipe penetrate through the heat storage tank body, are immersed into the heat storage medium and are communicated with the air above t
