The invention discloses an equipment box floor mounting and solar power supply method. According to the method, a concrete foundation, a foundation bolt, a horizontal sealed box body, a fixing bolt, arotatable solar support, a solar panel and a power supply line are involved, after a foundation pit is excavated between rail tracks, the concrete foundation is poured, the foundation bolt is arranged to fix the horizontal sealing box body, newly added equipment is arranged in the horizontal sealed box body, the rotatable solar support and the solar panel are fixed on the top of the horizontal sealed box body, the rotatable solar support can obtain the best solar light receiving effect through rotating to adjust angles, and the solar panel supplies power to the equipment in the horizontal sealed box body through the power supply line. According to the method, the train safety protection distance of the newly added equipment between the rail tracks is met, the influence of wind speed and rainwater on the newly-added equipment and train operation is avoided, the angle of the solar panel is adjusted through the rotatable solar support, the light receiving effect of the solar panel is improved while power is supplied for the equipment, and the problem of power supply of the newly added equipment between the rail tracks is solved.
