A device for isothermal compression, constant-pressure power generation and physical energy storage includes an air storage tank, a weight, a piston and a piston rod. An inner cavity of the air storage tank is divided into first to third chambers by first and second heat conducting baffles. The piston is arranged in the second chamber. The piston rod has a lower end connected with the piston and an upper end connected with the weight. First and second elastic sealing belts are arranged in the first and third chambers, respectively. The first chamber includes a first water injection port and a first water outlet above the first elastic sealing belt, and the third chamber includes a second water injection port and a second water outlet above the second elastic sealing belt. A bottom of the air storage tank includes an air injection port and a compressed air outlet.
