Description

Technical Field

[0001] This utility model relates to the field of solar water heater component technology, and more specifically, to a solar water heater storage tank. Background Technology

[0002] A solar water heater is a device that uses sunlight to produce hot water. It converts solar energy into heat energy to heat water. The working principle of a solar water heater is to convert the energy of sunlight into heat energy. This heat energy heats the water through a thermosiphon system and is then stored in a tank. Vacuum tube solar water heaters use vacuum tubes to collect solar radiation. The black heat-absorbing layer inside the tube absorbs sunlight, heating the water. Hot water rises and cold water sinks, forming a natural circulation process that ensures the water temperature in the tank continuously rises.

[0003] Patent CN217584914U discloses an improved solar water heater storage tank, including an outer cylinder, side sealing plates fixed to both ends of the outer cylinder, a water tank disposed between the outer cylinder and the axis of the two side sealing plates, and a liquid filling pipe, a hot circulation pipe, and a cold circulation pipe connected to the water tank. The inner wall of the outer cylinder is fitted with a heat insulation layer. Multiple supporting protrusions arranged in a ring array and in line contact with the outer wall of the water tank are integrally formed on the inner side of the heat insulation layer. A thermal insulation layer is filled between the water tank and the heat insulation layer, within the cavities of the multiple supporting protrusions. This invention transforms the original independent heat insulation layer into a composite heat insulation and thermal insulation layer structure. The inclusion of multiple ring-arrayed supporting protrusions and the thermal insulation layer on the inner side of the thermal insulation layer efficiently absorbs and stores heat between the water tank and the thermal insulation layer, while simultaneously preventing heat loss from the water tank. Compared to traditional heat insulation layer structures, this significantly improves the heat insulation and thermal insulation performance of the storage tank.

[0004] Although the device has many beneficial effects, the following problems still exist: While the water storage tank improves the heat preservation and insulation performance of the water storage tank, the thermal conductivity of scale and dirt is much lower than that of metal. If these impurities accumulate inside the collector tube or the water storage tank, they will seriously affect the heat transfer. This will cause the heat absorbed by the collector tube to be unable to be transferred to the water in time, thereby reducing the temperature of the hot water. In the long run, this will not only affect the quality of the hot water supply, but also increase energy consumption, because the system needs a longer time or a higher temperature to achieve the expected hot water effect.

[0027] Please see Figure 1-5 This utility model provides a technical solution:

[0028] A solar water heater storage tank includes a support frame 1, a storage tank body 2 fixedly mounted on the outer surface of the support frame 1, a plurality of equally spaced heat collection tubes 5 on the outer surface of the storage tank body 2, an operation box 9 inside the storage tank body 2, and further includes:

[0029] The self-cleaning component is located on the outer surface of the control box 9 and is used to clean the connection between the water storage tank body 2 and the heat collection pipe 5.

[0030] The heat preservation component, located inside the water storage tank body 2, is used to enhance the heat preservation of the water storage tank body 2. It absorbs solar energy through the heat collection pipe 5 and converts it into heat energy, which is then stored in the water storage tank body 2.

[0031] Furthermore, the self-cleaning assembly includes a rotating shaft 4, a first bevel gear 12, a second bevel gear 13, a third bevel gear 14, and a connecting shaft 15. Multiple equidistantly distributed third bevel gears 14 are rotatably connected to the inner wall of the operating box 9. The outer surfaces of the multiple third bevel gears 14 are perpendicularly meshed with second bevel gears 13. A connecting shaft 15 is rotatably connected between the inner walls of both sides of the operating box 9. Multiple second bevel gears 13 are fixedly connected to the connecting shaft 15. A first bevel gear 12 is rotatably connected to the inner wall of the other side of the operating box 9. The first bevel gear 12 meshes perpendicularly with one of the second bevel gears 13. A rotating shaft 4 is rotatably connected to the outer surface of the operating box 9. The rotating shaft 4 is connected to the first bevel gear 13. The bevel gear 12 is fixedly connected, and the rotating shaft 4 movably passes through the water tank body 2 and is sealed and fitted to the inner wall of the water tank body 2. A handle is fixedly connected to the end of the rotating shaft 4. Manually turning the handle will drive the rotating shaft 4 to rotate. The rotating shaft 4 is fixedly connected to the first bevel gear 12, so the first bevel gear 12 rotates accordingly. The first bevel gear 12 meshes perpendicularly with one of the second bevel gears 13, driving the second bevel gear 13 to rotate. Since multiple second bevel gears 13 are fixedly connected through the connecting shaft 15, all second bevel gears 13 will rotate synchronously. Each second bevel gear 13 meshes perpendicularly with a third bevel gear 14, driving the third bevel gear 14 to rotate.

[0032] Furthermore, the self-cleaning assembly also includes cleaning rollers 10 and scrapers 11. Multiple cleaning rollers 10 are rotatably connected to the outer surface of the operation box 9. Multiple annular scrapers 11 are fixedly connected to the outer surface of each cleaning roller 10. The multiple cleaning rollers 10 are fixedly connected to the corresponding third bevel gears 14.

[0033] Furthermore, limit grooves 6 are provided on both inner walls of the water storage tank body 2, and limit blocks 7 are fixedly connected to both outer surfaces of the operation box 9. The two limit blocks 7 are slidably connected to the corresponding limit grooves 6.

[0034] Furthermore, a protective box 3 is fixedly connected to the outer surface of the water storage tank body 2. A door is hinged to the outer surface of the protective box 3. An electric telescopic rod 8 is fixedly installed inside the protective box 3. The output end of the electric telescopic rod 8 passes through the water storage tank body 2 and is fixedly connected to the operation box 9. When the door of the protective box 3 is opened, the electric telescopic rod 8 is started, and the electric telescopic rod 8 pushes the operation box 9.

[0035] Furthermore, the insulation component includes a reflective aluminum foil layer 16, a high-density polyurethane foam layer 17, and a vacuum insulation layer 18. The water tank body 2 is composed of the reflective aluminum foil layer 16, the high-density polyurethane foam layer 17, and the vacuum insulation layer 18. The vacuum insulation layer 18 is bonded to the innermost layer of the water tank body 2 and fixedly connected to the inner wall of the water tank body 2, used to create a vacuum environment to significantly reduce heat conduction.

By reflecting heat radiation from the outside, it further reduces heat loss and enhances the insulation effect of the water tank.

[0036] Working principle: When the operator needs to use the solar water heater storage tank and cleans the connection between the storage tank body 2 and the collector pipe 5, first open the door of the protective box 3, then activate the electric telescopic rod 8. The electric telescopic rod 8 pushes the operating box 9, causing the limiting blocks 7 on both sides of the operating box 9 to slide within the limiting grooves 6, thereby pushing multiple cleaning rollers 10 towards the inner wall of the collector pipe 5. During the movement, the operating box 9 drives the rotating shaft 4 to move synchronously into the storage tank body 2. Then, manually turn the handle to rotate the rotating shaft 4. The rotating shaft 4 is fixedly connected to the first bevel gear 12, so the first bevel gear 12 rotates accordingly. The first bevel gear 12 meshes perpendicularly with one of the second bevel gears 13, driving the second bevel gear 13 to rotate. Since multiple second bevel gears 13 are fixedly connected through the connecting shaft 15, all second bevel gears 13 will rotate synchronously. Each second bevel gear 13 is connected to a third bevel gear. 14 is vertically engaged, driving the third bevel gear 14 to rotate. The third bevel gear 14 is fixedly connected to the cleaning roller 10, so the cleaning roller 10 will rotate with the rotation of the third bevel gear 14. The scraper 11 on the outer surface of the cleaning roller 10 rotates together with the cleaning roller 10, contacting the inner wall of the heat collection tube 5 and scraping off the dirt. The vacuum insulation layer 18 is bonded to the innermost layer of the water storage tank body 2. By creating a vacuum environment, it greatly reduces heat conduction, thereby effectively maintaining the heat in the water storage tank. The high-density polyurethane foam layer 17 is sprayed on the outside of the vacuum insulation layer 18 to form a dense heat insulation layer, further reducing heat loss. The reflective aluminum foil layer 16 is pasted on the outside of the high-density polyurethane foam layer 17. By reflecting the heat radiation from the outside, it further reduces heat loss and enhances the heat preservation effect of the water storage tank. When cleaning is not required, the electric telescopic rod 8 can be activated in reverse, thereby causing multiple cleaning rollers 10 to detach from the inside of the heat collection tube 5.
