The invention discloses a comprehensive energy system combining underground gravity energy storage with a heat pump. An upper rail is mounted on the ground, and a straight section of the upper rail extends to a shaft mouth; the lower track is mounted in a roadway and has the same structure as the upper track, and a straight section extends to the bottom of a vertical shaft; the support beam frame is arranged at the mouth of the vertical shaft, and the support beam is movably connected with the support beam frame; the motor generator and the winch are installed on the supporting beam. The heat pump heat (cold) supply unit is arranged beside an overground rail, the heat exchange coil is located in the weight carrier, one end of the heat exchange coil is connected with a first connector of the four-way valve, the other end of the heat exchange coil is sequentially connected with the throttling valve, the first side of the condenser/evaporator and a third connector of the four-way valve, an inlet and an outlet of the compressor are connected with a second connector and a fourth connector of the four-way valve respectively, and the second side of the condenser/evaporator is connected with a cold/heat user. According to the invention, the permeability of renewable energy sources can be improved, energy conservation and emission reduction are realized, the construction cost of the system is reduced, the occupied area is small, and site selection is flexible.
