A connecting pipe 11 is communicated with the outer surface of the left sealing cover 10 among the two sealing covers 10, and an outer connecting pipe 12 is rotatably connected to the outer surface of the connecting pipe 11. Through the sealing cover 10, the vacuum glass outer tube 1 can be sealed, reducing heat loss and avoiding leakage of the internal fluid medium at the same time. Through the connecting pipe 11 and the outer connecting pipe 12, it is more convenient for the staff to connect the external object to be heated.

[0035] The sealing cover 10 can be detached from the vacuum glass outer tube 1, making it more convenient for the staff to replace the sealing cover 10. The inner wall of the outer connecting pipe 12 is polished to reduce the wear when the outer connecting pipe 12 rotates, effectively increasing the service life of the device.

[0036] A threaded rod 13 is fixedly connected to the outer surface of the right sealing cover 10 among the two sealing covers 10, and a threaded tube 14 is threadedly connected to the outer surface of the threaded rod 13.

[0037] The threaded rod 13 can be detached from the sealing cover 10, and different sizes of the threaded rod 13 and the threaded tube 14 can be replaced according to the requirements of the installation position, effectively increasing the applicable range of the device and the practicality of the device.

[0038] There is a fixing plate 15 outside the outer tube 1 of the vacuum glass. Two telescopic rods 16 are fixedly connected to the upper surface of the fixing plate 15. The fixing plate 15 can support the device, and the telescopic rods 16 can be used to adjust the height of the outer tube 1 of the vacuum glass, effectively increasing the practicality of the device.

[0039] The two telescopic rods 16 can be adjusted to different heights, giving the outer tube 1 of the vacuum glass a certain angle, ensuring the flow of the fluid medium, ensuring the normal use of the device, and effectively increasing the applicable range of the device.

[0040] Two reinforcing ribs 17 are fixedly connected to the outer surface of each telescopic rod 16. The bottom surfaces of the four reinforcing ribs 17 are fixedly connected to the upper surface of the fixing plate 15. The reinforcing ribs 17 can strengthen the connection between the telescopic rods 16 and the fixing plate 15, preventing the device from falling off after long-term use and effectively increasing the safety of the device.

[0041] The reinforcing ribs 17 and the fixing plate 15 are connected by welding, effectively preventing the device from being damaged during use and increasing the stability and safety of the device.

[0042] The output end of the telescopic rod 16 is fixedly connected to a lifting plate 18. A detachable mounting block 19 is installed on the upper surface of the lifting plate 18. A fixing ring 20 is fixedly connected to the outer surface of the outer tube 1 of the vacuum glass. The top of the mounting block 19 is hinged to the outer surface of the fixing ring 20 by a pin shaft. The outer tube 1 of the vacuum glass can be connected to the telescopic rod 16 through the lifting plate 18, the mounting block 19 and the fixing ring 20. The outer tube 1 of the vacuum glass can be driven to move by the telescopic rod 16.

[0043] The outer surface of the lifting plate 18 is passivated, effectively preventing the staff from being scratched during operation and increasing the safety of the device. The inner wall size of the mounting block 19 is the same as the outer size of the outer tube 1 of the vacuum glass, so that the fixing ring 20 can be installed on the surface of the outer tube 1 of the vacuum glass without falling off.

[0044] An installation frame 21 is fixedly connected to the outer surface of the lifting plate 18. A plug rod 22 is slidably connected to the inner wall of the hole on the installation frame 21.

[0045] The plug rod 22 is made of a material with high hardness, which can bear a large weight without breaking, ensuring the safety during the operation of the device and effectively increasing the practicality of the device.

[0046] A movable disk 23 is fixedly connected to the outer surface of the inserting rod 22. A telescopic spring 24 for driving the automatic reset of the movable disk 23 is fixedly connected to the back surface of the movable disk 23. The other end of the telescopic spring 24 is fixedly connected to the outer surface of the mounting bracket 21. The movable disk 23 enables the staff to pull the inserting rod 22 more conveniently. The elastic force generated when the telescopic spring 24 deforms can drive the automatic reset of the movable disk 23, which can effectively reduce the operation difficulty of the device.

[0047] A protective pad can be sleeved on the outer surface of the movable disk 23, which can protect the palm of the staff, avoid harm to the palm of the staff, and increase the comfort of the staff at the same time.

[0048] Working principle: When the device is used, it needs to be installed at the required position first, and then the height of the telescopic rod 16 is adjusted so that the heights of the two telescopic rods 16 are deviated, so that the outer tube 1 of the vacuum glass is in an inclined state, which can ensure the flow of the fluid medium. Then when sunlight shines on the outer tube 1 of the vacuum glass, the purpose of concentrating sunlight can be achieved. Then the anti-reflection layer 3 reduces the reflection of sunlight. The solar energy can be converted into heat through the photo-thermal conversion layer 5. The heat can be absorbed through the heat absorption layer 6, and then the heat is transmitted to the heat conduction layer 7. Then the metal heat absorption inner tube 9 can heat the internal fluid medium, and the purpose of heat collection can be achieved.

[0049] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
