[0022] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0023] The first implementation method:

[0024] Figure 1-7 A vacuum tube type solar collector is shown, comprising a heat collecting tube 1, the outer end of the heat collecting tube 1 is fixedly connected with a threaded tube 2, the outer end of the threaded tube 2 is threadedly connected with a moving tube 3, the outer end of the moving tube 3 is provided with a round tube 4, a lubricant is contained in the round tube 4, a rubber block 5 is slidably inserted inside the round tube 4, the upper end of the rubber block 5 is fixedly connected with a moving rod 6, the lower end of the round tube 4 is fixedly connected with a nozzle 7, the outer end of the round tube 4 is provided with a round block 8, the end of the round block 8 away from the moving tube 3 is fixedly connected with a pair of fixed blocks 9, the ends of the pair of fixed blocks 9 close to each other are provided with plug-in holes, the outer end of the round tube 4 is fixedly connected with a pair of plug-in blocks 10 rotatably connected to the plug-in holes, the end of the round block 8 close to the moving tube 3 is fixedly connected There is a limiting seat 11, and the outer end of the movable tube 3 is provided with a limiting groove 12 which is rotatably connected to the limiting seat 11. When the round block 8 rotates, the limiting seat 11 will rotate in the limiting groove 12. The limiting seat 11 can prevent the round block 8 from falling off the movable tube 3. A pair of limiting blocks 13 are fixedly connected to the right end of the movable tube 3. The limiting blocks 13 can be used to limit the position of the movable tube 3 from the end of the heat collecting tube 1. A feeding pipe 14 is fixedly connected to the outer end of the circular tube 4, and a sealing block 15 is inserted into the inside of the feeding pipe 14. A pulling block 16 is fixedly connected to the end of the sealing block 15 away from the feeding pipe 14. There is a gap between the outer end of the circular tube 4 and the round block 8, and the end of the round block 8 away from the circular tube 4 is rotatably connected to the outer end of the movable tube 3.

[0025] The present invention can be realized that when in use, the movable tube 3 is rotated to move on the threaded tube 2 to adjust its position on the heat collecting tube 1, and the movable tube 3 is used to protect the end of the heat collecting tube 1, thereby reducing the inconvenience caused to personnel when disassembling the heat collecting tube 1 due to foreign matter and dust adhering to the end of the heat collecting tube 1. When disassembling, the round block 8 needs to be rotated ninety degrees clockwise, thereby rotating the round tube 4 ninety degrees, and then moving the round tube 4 back and forth to adjust the inclination of the round tube 4 in the horizontal direction, thereby adjusting the position of the nozzle 7. After adjusting the position of the nozzle 7, the movable rod 6 is pushed, and the lubricant in the round tube 4 is pushed by the rubber block 5, thereby allowing the lubricant to be sprayed to the end of the heat collecting tube 1 through the nozzle 7, and the end of the heat collecting tube 1 is lubricated by the lubricant, and then the heat collecting tube 1 is rotated to be removed from the solar water heater. Therefore, when disassembling the collector, there is no need for personnel to prepare disassembly tools and lubricants in advance, which not only improves the convenience of personnel when disassembling it, but also reduces the workload of personnel.

[0026] The second implementation method:

[0027] Based on the first embodiment, this embodiment adds structures such as a protection tube 17 and related contents, and the rest of the parts are consistent with the first embodiment.

[0028] Figure 2-3 and Figure 5 It is shown that a protective tube 17 is provided at the upper end of the circular tube 4, a pair of reinforcing blocks 18 are fixedly connected to the lower end of the protective tube 17, a pair of reinforcing grooves 19 movably connected to the reinforcing blocks 18 are opened at the upper end of the circular tube 4, a pair of side ends of the reinforcing blocks 18 are coated with a magnetic coating 1 20, and the inner wall of the reinforcing groove 19 is coated with a magnetic coating 21.

[0029] This solution can be implemented. When in use, the protective tube 17 needs to be installed on the circular tube 4 so that the reinforcement block 18 is inserted into the reinforcement groove 19. The reinforcement block 18 can improve the stability of the protective tube 17 on the circular tube 4 and prevent the protective tube 17 from rotating on the circular tube 4. At the same time, the magnetic coating 1 20 will be adsorbed together with the magnetic coating 2 21, thereby improving the stability of the reinforcement block 18 in the reinforcement groove 19. The protective tube 17 can prevent the lubricating oil from being pushed out of the circular tube 4 due to people accidentally touching the moving rod 6.

[0030] In view of current practical needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of this utility model.
