Description

Technical Field

[0001] This utility model relates to the field of solar heating tube technology, and in particular to a solar heating tube that is easy to clean. Background Technology

[0002] With the advancement of technology and people's increasing awareness of the environment, solar energy, as a clean energy source, is being used more and more in people's daily lives. Solar water heaters used by ordinary people typically have a water tank and heating elements connected to the tank. Sunlight shines on the heating elements, thus heating the water for daily use.

[0003] A search revealed a Chinese patent publication number CN218210133U, which discloses an internal sleeve for a vacuum tube in a solar collector. The sleeve includes a collector tube, a fixed sleeve fixedly fitted onto the collector tube, and a fixed circular plate fixedly fitted onto the fixed sleeve. A sealing ring is fixedly installed on the right side of the fixed circular plate and is fixedly fitted onto the fixed sleeve. This patent moves the collector tube and the fixed sleeve towards a pre-drilled mounting hole in the water tank of a solar water heater. After the fixed sleeve is inserted into the mounting hole, the moving tube is rotated away from the water tank, allowing it to be inserted into the pre-drilled mounting hole on the solar panel. This prevents the collector tube from being unable to move vertically aligned with the pre-drilled mounting hole in the water tank, thus avoiding damage to the collector tube.

[0004] However, while the rubber ring and telescopic tube protect the threads, the telescopic tube may age and fail after prolonged use, affecting the protection of the threads. Utility Model Content

[0027] Example 1

[0028] An easy-to-clean solar heating tube, such as Figures 1 to 3As shown, the device includes a transparent outer tube 1, a fixed sleeve 2 at one end of the transparent outer tube 1, and a sliding tube 3 that is slidably fitted to the outer wall of the other end of the transparent outer tube 1. A plug 4 is fixed to the outer wall of one end of the sliding tube 3, and a fixed post 5 is fixed to the outer wall of one end of the transparent outer tube 1. The fixed post 5 is located inside the sliding tube 3, and an annular plate 6 is provided on the outer wall of the fixed post 5. Multiple locking blocks 7 are fixedly connected to the side wall of the annular plate 6 by means of elastic steel sheets. The elastic steel sheets are made of stainless steel. A limiting plate 8 is fixed to the inner wall of the sliding tube 3, and the limiting plate 8 is in a limiting fit with the multiple locking blocks 7. A movable frame 11 is slidably connected to the end of the sliding tube 3 away from the plug 4. A compression ring 10 located on one side of the limiting plate 8 is fixed to one end of the movable frame 11, and the compression ring 10 is laterally suction-fixed to the sliding tube 3. A fixing plate 9 is fixedly connected to the side wall of the fixed post 5 away from the transparent outer tube 1, and an annular protrusion that is in a limiting fit with the fixing plate 9 is provided on the inner wall of the sliding tube 3.

[0029] A collar 13 is fitted on the outer wall of the transparent outer tube 1 near the fixed sleeve 2. One end of the collar 13 is threaded to the fixed sleeve 2. A sealing ring 14 is fixedly connected to the outer wall of the collar 13 near the fixed sleeve 2.

[0030] A cleaning component 19 is provided on one side of the transparent outer tube 1. The cleaning component 19 includes a cleaning ring and a linear drive mechanism. The linear drive mechanism is a mature existing technology. The cleaning ring slides with the outer wall of the transparent outer tube 1. The linear drive mechanism is electrically connected to an external controller.

[0031] During installation, insert the fixing sleeve 2 into the pre-drilled mounting hole on the water tank of the solar water heater, then push the sliding tube 3. The sliding tube 3 drives the plug 4 to insert into the pre-drilled fixing hole on the solar bracket. As the sliding tube 3 moves, it drives the limiting plate 8 to move. The limiting plate 8 presses against the locking block 7, causing the locking block 7 to move away from the limiting plate 8. After the plug 4 is fully inserted into the fixing hole, the limiting plate 8 will pass over the locking block 7. The elasticity of the elastic steel sheet causes the locking block 7 to reset. The locking block 7 limits the sliding tube 3 by restricting the limiting plate 8. The fixing plate 9 cooperates with the annular protrusion to restrict movement. The sliding tube 3 is disengaged from the transparent outer tube 1. Then, the collar 13 is rotated, and the sealing ring 14 is tightly fitted with the reserved mounting hole to seal, thus completing the installation of the heating tube. When disassembling, the moving frame 11 is pushed, and the squeezing ring 10 squeezes the locking block 7 to move away from the limiting plate 8. Then, the sliding tube 3 and the moving frame 11 move synchronously, and the limiting plate 8 and the squeezing ring 10 move synchronously, releasing the limiting plate 8 and the locking block 7. The user can control the cleaning component 19 to clean the outer wall of the transparent outer tube 1 to prevent dust from adhering to the outer wall of the transparent outer tube 1.

[0032] The sliding tube 3 is limited by the locking block 7, the limiting plate 8, the compression ring 10 and the moving frame 11. The locking block 7 and the limiting plate 8 are used to limit the sliding tube 3. All parts are located in the sliding tube 3 and are not affected by the external environment. Compared with the threaded movement, the operation speed is faster and more convenient.

[0033] Example 2

[0034] An easy-to-clean solar heating tube is described in this embodiment, which is based on Embodiment 1 and makes the following improvements, such as... Figure 4 , Figure 5 As shown, a heated inner tube 12 is provided inside the transparent outer tube 1, and a reflector 15 for reflecting light is provided on the inner wall of the transparent outer tube 1. A rotating ring 16 is rotatably connected to the outer wall of the transparent outer tube 1. The inner wall of the rotating ring 16 is fixedly connected to the reflector 15. A limiting toothed ring 17 is connected to one side of the rotating ring 16. A limiting ball head 18 is provided on the inner wall of the transparent outer tube 1 to limit and cooperate with the limiting toothed ring 17. The limiting ball head 18 is connected to the inner wall of the transparent outer tube 1 through an elastic element.

[0035] During heating, the reflector 15 reflects sunlight, allowing the lower part of the inner tube 12 to be heated by sunlight, making full use of solar energy. The reflector 15 can be rotated by the rotating ring 16 to adjust its angle. During the rotation, the limiting tooth ring 17 presses the limiting ball head 18 away from the limiting tooth ring 17. After stopping, the limiting tooth ring 17 and the limiting ball head 18 cooperate to limit the reflector 15, so that the reflector 15 can be adjusted in position according to different regions and seasons, improving the applicability of the device.

[0036] By setting up a reflector 15, sunlight can be reflected, so that the lower part of the fixed sleeve 2 is heated by sunlight, making full use of solar energy.

[0037] By incorporating a rotating ring 16, a limiting toothed ring 17, and a limiting ball head 18, the angle of the reflector 15 can be adjusted, allowing the reflector 15 to be positioned according to different regions and seasons, thus improving the applicability of the device.

[0038] Working principle: During installation, insert the fixing sleeve 2 into the pre-drilled mounting hole on the water tank of the solar water heater, then push the sliding tube 3. The sliding tube 3 drives the plug 4 into the pre-drilled fixing hole on the solar bracket. As the sliding tube 3 moves, it drives the limiting plate 8 to move. The limiting plate 8 presses against the locking block 7, causing the locking block 7 to move away from the limiting plate 8. After the plug 4 is fully inserted into the fixing hole, the limiting plate 8 will pass over the locking block 7. The elasticity of the elastic steel sheet causes the locking block 7 to reset. The locking block 7 limits the limiting plate 8, preventing the sliding tube 3 from resetting. The fixing plate 9 cooperates with the annular protrusion to prevent the sliding tube 3 from disengaging from the transparent outer tube 1. Then, rotate the collar 13, and the sealing ring 14 will fit tightly against the pre-drilled mounting hole for sealing, completing the installation of the heating tube. During disassembly, push the moving bracket 11, and the squeezing ring 10 will squeeze the locking block 7 away from the limiting plate 8. The position plate 8 moves in the direction, and then the sliding tube 3 and the moving frame 11 move synchronously. The limiting plate 8 and the squeezing ring 10 move synchronously, releasing the limiting plate 8 and the locking block 7. The user can control the cleaning component 19 to clean the outer wall of the transparent outer tube 1 to prevent dust from adhering to the outer wall of the transparent outer tube 1. When heated, the reflector 15 reflects sunlight, so that the lower part of the inner tube 12 is heated by sunlight, making full use of solar energy. The reflector 15 can be rotated by the rotating ring 16 to adjust the angle of the reflector 15. During the rotation, the limiting tooth ring 17 squeezes the limiting ball head 18 away from the limiting tooth ring 17. After stopping, the limiting tooth ring 17 and the limiting ball head 18 cooperate to limit the reflector 15, so that the reflector 15 can be adjusted according to different regions and seasons, improving the applicability of the device.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
