A deep-sea multi-energy integrated platform for complementary power generation, production, living and exploration, comprising: a platform body, comprising: three column cabins, a lower platform housing connected to the bottoms of the column cabins, an upper platform housing connected to the tops of the column cabins, and several spaced current guide columns connected between the lower platform housing and the upper platform housing, wherein the column cabins, the current guide columns, the upper platform housing and the lower platform housing are mutually connected to form a triangular platform with a hollow cavity, and a net is disposed in the hollow cavity to form a mariculture zone; a sustainable power supply system, comprising: a wind-driven generator disposed at an end of a top surface of the upper platform housing to convert wind energy into electric energy and transmit the electric energy to an energy storage unit, a solar panel disposed above a middle portion of the top surface of the upper platform housing to convert solar energy into electric energy and transmit the electric energy to the energy storage unit, a wave power generation apparatus disposed between the current guide columns to convert wave energy into electric energy and transmit the electric energy to the energy storage unit, and several tidal current power generation apparatuses disposed on a top surface of the lower platform housing to convert tidal current energy into electric energy and transmit the electric energy to the energy storage unit; the wave power generation apparatus, comprising: a wave absorbing float and a closed power generation device compartment that are disposed among the current guide columns; a crankshaft and a wave energy conversion element hinged to the crankshaft are disposed inside the power generation device compartment, wherein both ends of the crankshaft extend out of the power generation device compartment and are then connected to two supporting arms of the wave absorbing float through hinged shaft supports respectively, such that the wave absorbing float is capable of driving the crankshaft to move synchronously, thereby driving the wave energy conversion element to generate power; and a cross section of a segment of the current guide column close to the lower platform housing is an inverted trapezoid that gradually expands from outside to inside, such that a trapezoidal region that gradually shrinks from outside to inside is formed between every pair of current guide columns and capable of enhancing the tidal current energy so as to improve the power generation efficiency of the tidal current power generation apparatus. a platform body, comprising: three column cabins, a lower platform housing connected to the bottoms of the column cabins, an upper platform housing connected to the tops of the column cabins, and several spaced current guide columns connected between the lower platform housing and the upper platform housing, wherein the column cabins, the current guide columns, the upper platform housing and the lower platform housing are mutually connected to form a triangular platform with a hollow cavity, and a net is disposed in the hollow cavity to form a mariculture zone;
