1. A device for supplying cold energy, heat energy and electrical energy by efficiently converting renewable deep-space energies, comprising a solar-energy conversion device, a radiation refrigeration device, a rotary bracket, a dip-angle adjustment component, and a support base,
wherein the solar-energy conversion device and the radiation refrigeration device are connected to the rotary bracket in a mutually perpendicular manner, and the rotary bracket is connected to the dip-angle adjustment component, wherein the dip-angle adjustment component is connected to the support base; the dip-angle adjustment component is configured to adjust a dip angle between the rotary bracket and a horizontal plane; and the rotary bracket is configured to drive the solar-energy conversion device and the radiation refrigeration device to rotate, such that a sunward side of the solar-energy conversion device is always perpendicular to light rays irradiated by a sun, and a reflective surface of the radiation refrigeration device is always parallel to the light rays irradiated by the sun;
wherein the radiation refrigeration device comprises light-transmitting thermal insulation materials, light-transmitting radiation refrigeration materials, light-ray reflective plates, and a cooled medium channel, and the light-transmitting thermal insulation materials, the light-transmitting radiation refrigeration materials, and the light-ray reflective plates are stacked from outside to inside on both sides of the cooled medium channel;
uncontrollable diffuse-reflection light rays in atmosphere pass through the light-transmitting thermal insulation materials and the light-transmitting radiation refrigeration materials in sequence, are reflected by the light-ray reflective plates, then pass through the light-transmitting radiation refrigeration materials and the light-transmitting thermal insulation materials in sequence and return to the atmosphere, without any energy exchange with an outside world in a whole process; and
the light-transmitting radiation refrigeration materials transfer heat to a deep space of a universe in a form of radiant light waves of 8 μm-13 μm, and cold energy generated by the light-transmitting radiation refrigeration materials are transferred by heat conduction to a cooled medium in the cooled medium channel via the light-ray reflective plates, thereby allowing radiation refrigeration;
wherein the light-transmitting thermal insulation materials are vacuum glass or transparent heat shields;
wherein the dip-angle adjustment component comprises a first lifting rod and a second lifting rod, wherein the first lifting rod and the second lifting rod are spaced apart and disposed on the support base; and both ends of the rotary bracket are connected to a lifting end of the first lifting rod and a lifting end of the second lifting rod, respectively.
