The experimental methods in the following examples are conventional methods unless otherwise specified, and materials, reagents and the like used in the following examples are commercially available unless otherwise specified.

Embodiment 1 as shown in fig. 1, 2, 3 and 4, a secondary heat exchange double-layer vacuum tube solar thermal collector comprises a support frame 1, a collector body 11 is fixedly installed at the upper end of the support frame 1, inner slide rails 12 are respectively installed at the left and right side ends of the support frame 1, side slide bars 26 are respectively installed in each inner slide rail 12 in a sliding manner, a connecting plate 25 is fixedly installed at the side end of each side slide bar 26, the weight of a water accumulating box 24 is increased along with the increase of rainwater, the gravity of the two side slide bars 26 can drive the two side slide bars 26 to slide downwards, micro pulleys are arranged at the lower ends of the two side slide bars 26, the side slide bars 26 can slide conveniently, the two side slide bars 26 move to drive a plurality of micro springs 27 to compress and deform, meanwhile, the two water accumulating boxes 24 move to drive a first scraper 2 to move, the first scraper 2 moves to drive a second scraper 22 to move, the first scraper 2 and the second scraper 22 move on the surface of the collector body 11, a water accumulating box 24 is fixedly installed at the upper end of each connecting plate 25, a tapered tube 29 is fixedly installed at the upper end of each water accumulating box 24, and the front end of the first scraper 2 is fixedly installed with the second scraper 22.

The inner wall of each inner slide rail 12 is fixedly provided with an inner baffle 13, two miniature springs 27 are fixedly arranged between each side slide bar 26 and the inner baffle 13, the lower end part of the water accumulation tank 24 is fixedly provided with a drain pipe 28, the conical pipe 29 can quickly accumulate rainwater, the joint of the conical pipe 29 and the water accumulation tank 24 is small, the rainwater can be effectively prevented from being scattered outwards when the water accumulation tank 24 moves, the first scraper blade 2 and the second scraper blade 22 move, the first scraper blade 2 can slightly rotate between the two water accumulation tanks 24, the friction force is effectively prevented from being large, the rotating shaft 23 is rotatably arranged between the first scraper blade 2 and the two water accumulation tanks 24, at least two rubber blocks 21 are fixedly arranged between the first scraper blade 2 and the second scraper blade 22, and the cross sections of the lower sections of the first scraper blade 2 and the second scraper blade 22 are V-shaped.

The working principle is as follows:

first, the support frame 1 supports the heat collector body 11, when the heat collector is in rainy days, rainwater can enter the tapered pipe 29, the rainwater enters the water accumulating tank 24 through the tapered pipe 29, meanwhile, a part of rainwater can be discharged outwards through the drain pipe 28, but because the drainage speed of the drain pipe 28 is slow, the rainwater in the water accumulating tank 24 can be gradually increased, the weight of the water accumulating tank 24 is increased along with the increase of the rainwater, the gravity of the two side slide bars 26 can drive the two side slide bars 26 to slide downwards, the lower end parts of the two side slide bars 26 are provided with the micro pulleys, the side slide bars 26 can slide conveniently, the two side slide bars 26 move to drive the micro springs 27 to compress and deform, meanwhile, the two water accumulating tanks 24 move to drive the first scraper bar 2 to move, the first scraper bar 2 moves to drive the second scraper bar 22 to move on the surface of the heat collector body 11, meanwhile, the first scraper bar 2 and the second scraper bar 22 move on the surface of the heat collector body 11, when the day, the rainwater in the water accumulating tank 24 can be discharged outwards through the drain pipe 28, at this moment, the first scraper bar 2 and the second scraper bar 22 can move upwards in a clean day, the dust can be effectively cleaned, and the heat collector body 11 can be cleaned, thereby, the rainwater can be effectively cleaned, the heat collector body 11, and the rainwater can be effectively cleaned, and the dust can be effectively cleaned, and the heat collector body 11.

The second step, because the upper end opening of conical duct 29 is great, consequently conical duct 29 can save the rainwater fast, conical duct 29 and ponding box 24 junction diminish, can prevent effectively that ponding box 24 from when removing, the rainwater is outwards unrestrained, first scraper blade 2 and second scraper blade 22 are when removing, first scraper blade 2 can take place slight rotation between two ponding boxes 24, effectively prevent to lead to heat collector body 11 surface scratch because of frictional force is great, separate interior slide rail 12 inner wall with interior baffle 13, the user can install two sets of devices on support frame 1, thereby effectively adapt to the heat collector body 11 of different length, the practicality of device has been improved greatly.
