This utility model discloses a variable tilt angle solar vacuum tube collector, relating to the technical field of solar energy tilt angle variable devices. It includes a heat exchange box, a support frame mounted at the lower end of the heat exchange box, a connecting rod hinged to one side of the middle section of the support frame, and a support platform hinged to the other end of the connecting rod. A protective cover is fixed to the front end of the support platform, and multiple equidistant vacuum tube collectors are installed in the support platform near the heat exchange box. A tilt angle changing component is installed below one side of the support frame, and an intelligent rotating component is installed inside the support platform. In this utility model, the cooperation of a worm gear, worm wheel, first gear, and tooth groove adjusts the tilt angle of the support platform, improving solar energy absorption efficiency. A drive motor drives the drive gear, which, via a belt, engages with a second gear at the lower end of the vacuum tube collector. Combined with a first and second sealed bearing, this solves the problem of uneven heat absorption caused by the fixed direction of the vacuum tube collector, improving the uniformity and effectiveness of heat absorption.
