Due to different applications, solar collectors and their matching systems are classified into many types with different names, such as solar cookers for cooking, solar water heaters for producing hot water, solar dryers for drying items, solar furnaces for smelting metals, as well as solar houses, solar thermal power plants, solar desalination plants, and so on.

[0003] Publication No. CN211927300U discloses a solar collector testing device. This patent uses a fixed frame and a crossbar, which are interlocked and fixed by a first positioning screw. A protective sleeve is affixed to the outer wall of the fixed frame to facilitate operator gripping and rotation. A slider slides along the outer wall of the fixed frame through a slot. The positioning hole at the top of the crossbar facilitates the fixing of the bottom of the collector tube. This enhances the fixing performance and allows for easy disassembly.

When fixing the collector 3, the collector 3 is placed on the top of the support table 102, and then the hand wheel is rotated to drive the bidirectional threaded rod 202 to rotate. The position of the positioning column 208 is adjusted according to the position of the mounting hole 301 on the collector 3 by moving the sliding sleeve 207. After the bidirectional threaded rod 202 is rotated, the threaded sleeve 203 can be moved, thereby moving the square rod 206.

The heating efficiency of the collector 3 can be tested. When the collector 3 is disassembled, the positioning rod 210 is retracted into the positioning column 208 by rotating the screw 213, and the two square rods 206 are moved away from each other by reversely rotating the hand wheel, so that the collector 3 is not limited. The collector 3 can be taken down. The fixed assembly 2 can conveniently fix collectors 3 of different sizes, can ensure the reliability of fixation, and can conveniently disassemble the collector 3 by the staff, thereby improving the convenience and practicality.

[0032] When the collector 3 is fixed and the heating efficiency is tested, the support table 102 can be raised by the extension of the electric push rod 103, the angle of the collector 3 can be changed, sunlight can be directly incident on the collector 3, the handle 113 is rotated to drive the rotating rod 111 to rotate, the rotating rod 111 is rotated to drive the worm 109 to rotate through the meshing of the first bevel gear 110 and the second bevel gear 112, the worm 109 is rotated to drive the rotating column 106 to rotate through the meshing of the worm wheel 107, so that the movable plate 101 can be rotated.
