AI Technical Summary
Technical Problem
Traditional solar vacuum tube collectors have a fixed tilt angle, which cannot adapt to dynamic changes in solar altitude and azimuth angles, resulting in low heat absorption efficiency and serious energy waste.
Method used
A variable tilt solar vacuum tube collector is used. The tilt angle and rotation of the vacuum tube collector are adjusted by a worm gear mechanism and a drive motor to drive the gear belt. The cooperation between the sliding block and the sliding table ensures the stability of the structure.
Benefits of technology
It improves solar energy absorption efficiency and heat absorption uniformity, solves the problem of uneven heat absorption caused by fixed tilt angle, and extends the service life of the equipment.

Abstract
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.
