Highly cold mountain area anti-freeze water storage device utilizing terrestrial heat and solar energy

The invention belongs to the technical field of anti-freeze water storage and discloses a highly cold mountain area anti-freeze water storage device utilizing terrestrial heat and solar energy. The highly cold mountain area anti-freeze water storage device is provided with a water pool; a terrestrial heat exchange shaft is excavated at the bottom of the water pool; the terrestrial heat exchange shaft can exchange heat with underground rock mass to absorb energy; the temperature of water in the water pool is increased to prevent water freezing, so that the problem of difficult water using in the frontier defense first-line grass-roots troops in Tibet is solved, and good social and military benefits are achieved; a sunlight shed is arranged on the upper part of the water pool and can absorbsolar energy; people can enter the water pool through a crawling ladder below a manhole to maintain the water pool, the stable air pressure in the water pool can be ensured through a ventilation opening; a second steel pipe i
