The utility model discloses a solar vacuum tube collector which comprises a supporting frame, a supporting plate, a vacuum tube and a heat preservation shell, the supporting plate is fixedly installed on the front surface of the lower end of the supporting frame, the heat preservation shell is fixedly installed on the front surface of the upper end of the supporting frame, and the vacuum tube is fixedly installed between the heat preservation shell and the supporting plate. A moving block is movably embedded in the rear portion of the supporting frame, and a transferring frame is movably installed on the moving block. According to the solar vacuum tube collector, when a certain vacuum tube needs to be detached, a rotary knob of the supporting frame is rotated, the rotary knob drives the threaded rod to rotate, at the moment, the moving block can drive the transferring frame to move on the threaded rod, after the transferring frame moves to the position of the designated vacuum tube, the transferring frame is pushed forwards, and the vacuum tube is detached. In this way, in the process of disassembling the vacuum tube, the vacuum tube does not need to be held by one hand, and therefore the disassembling process is more convenient and faster.

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.
