Description

Technical Field

[0001] This invention relates to the field of solar water heater technology, specifically a natural circulation solar water heater. Background Technology

[0002] Natural circulation solar water heaters are systems that use solar energy to heat cold water. Natural circulation solar water heating systems are a type of solar water heating system. Natural circulation solar water heating systems rely on the temperature difference between the collector and the storage tank to form a thermosiphon pressure head, which causes the water to circulate in the system. At the same time, the useful energy gained from the collector is continuously stored in the storage tank by heating the water.

[0003] For example, announcement number CN208090987U discloses "a follow-up solar water heater", which includes a collector, a water tank and a mounting frame. The collector and the water tank are connected by a flow pipe. The mounting frame is set on the collector and is used to fix the position of the collector. The mounting frame includes a mounting base, a rotating component and a control component. The rotating component is set on the mounting base and the mounting base is movably connected to the collector through the rotating component. The control component is set on the mounting base and the collector.

[0004] For example, the announcement number CN104197550B discloses "a non-powered circulating instantaneous solar water heater", in which the solar collector is installed in a flat box and connected to the hot water tank. The flat box is fixed on the bracket of the adjustment bracket. One end of the hot water output pipe is connected to the hot water tank, and the other end is equipped with a switch and a drain device.

[0005] However, in existing technologies, the position and angle of the solar collector can only be manually adjusted according to the angle of sunlight in different seasons, or the angle can be changed vertically according to the changes in the angle of sunlight during the day. In the current usage environment, with the popularization of high-rise residential buildings, when installing natural circulation solar water heaters in high-rise residential buildings, the solar collectors are generally installed on the exterior wall surface of the building's balcony. Manually adjusting the position and angle of the solar collector requires people to work at height, which is costly and dangerous. It is not convenient to adjust the position and angle of the solar collector. While adjusting the vertical angle of the solar collector by rotating the components can improve the utilization rate of sunlight, it cannot adjust the horizontal angle of the solar collector. This results in large fluctuations in the utilization rate of solar energy by the natural circulation solar water heater in different seasons, causing the working performance of the natural circulation solar water heater to be unstable. Summary of the Invention

[0006] The purpose of this invention is to provide a natural circulation solar water heater to solve the problem mentioned in the background art, which requires manual adjustment of the position and angle of the collector, which requires high-altitude work. This adjustment method is costly and has a high risk factor, and is not convenient for adjusting the position and angle of the collector. Although adjusting the vertical angle of the collector by rotating the component can improve the utilization rate of sunlight, it cannot adjust the horizontal angle of the collector.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. In this invention, high-pressure gas pushes the No. 1 piston push rod upward along the No. 1 piston shell, pushing the No. 2 connector, the No. 2 connecting frame, and the upper end of the solar collector to adjust the vertical angle of the solar collector. When it is necessary to adjust the horizontal angle of the solar collector, the No. 6 control valve is opened, and high-pressure air enters the No. 2 piston shell through the No. 5 and No. 6 gas supply pipes. The No. 2 piston push rod pushes the rack to adjust the horizontal angle of the No. 2 connecting plate, thereby achieving the purpose of adjusting the horizontal angle of the solar collector. By adjusting the vertical and horizontal angles of the solar collector, the solar collector can make full use of sunlight and improve the performance of the solar collector in heating cold water.

[0019] 2. In this invention, high-pressure gas generated by the pressurized hot water storage tank is collected through a high-pressure gas storage tank. The high-pressure gas generated by the water heater components during operation is stored and utilized through the high-pressure gas storage tank. When the angle of the collector needs to be adjusted later, control valve No. 4 is opened. The high-pressure gas inside the high-pressure gas storage tank first enters No. 4 through No. 3 gas supply pipe, and then enters No. 6 through No. 4 gas supply pipe. The high-pressure gas output from No. 4 gas supply pipe serves as the power source for the lifting of piston rod No. 1, and the high-pressure gas output from No. 6 gas supply pipe serves as the power source for the lifting of piston rod No. 2. By using high-pressure gas generated by solar heating of water as a power source, the use of electrical energy is reduced, thereby making full use of solar energy.

[0020] 3. In this invention, when installing the solar collector outdoors, the mounting plate and the mounting limiting plate are first installed and fixed on the outdoor wall surface. Then, the adjustment mechanism on the upper part of the second fixing frame and the solar collector are installed and fixed by inserting the mounting plate into the mounting limiting plate. The height of the support plate is adjusted by rotating the threaded adjustment rod, thereby adjusting the height of the mounting plate and the second fixing frame. This avoids the installation height of the solar collector being too high or too low, which could cause problems with the circulation of water between the pressurized hot water storage tank and the inside of the solar collector.

[0021] 4. In this invention, when the second connecting plate rotates to adjust and reset the horizontal angle of the solar collector, the second connecting plate will drive the arc-shaped slider to slide along the arc-shaped slide rail. The arc-shaped slide rail limits the rotation of the second connecting plate, improving the stability of the second connecting plate during rotation. At the same time, the arc-shaped slider supports the second connecting plate, improving the stability of the upper component of the second connecting plate during use. The limiting guide rail limits the movement of the rack, improving the stability of the rack during movement. Attached Figure Description

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1

[0034] Reference Figures 1-9As shown: A natural circulation solar water heater includes a water heater assembly 1, which includes a pressurized hot water storage tank 11 and a collector 12. The pressurized hot water storage tank 11 is installed indoors, and the collector 12 is installed outdoors. The pressurized hot water storage tank 11 and the collector 12 are interconnected through a first connecting water pipe 13 and a second connecting water pipe 14. A drive mechanism 5 is installed on the top of the pressurized hot water storage tank 11, and an adjustment mechanism 2 is installed on the bottom of the collector 12. An installation mechanism 3 is fixedly connected to one side of the adjustment mechanism 2. The adjustment mechanism 2 includes a vertical angle adjustment component and a horizontal angle adjustment component. The vertical angle adjustment component is used to adjust the vertical angle of the collector 12, and the horizontal adjustment component is used to adjust the horizontal angle of the collector 12. The drive mechanism 5 is fixedly connected to the adjustment mechanism 2, and the drive mechanism 5 is used to collect and store the high-pressure gas generated when the water inside the pressurized hot water storage tank 11 boils. The drive mechanism 5 uses the stored high-pressure gas as a power source to provide power to the adjustment mechanism 2. The installation mechanism 3 is fixedly connected to the outdoor wall. A cold water inlet pipe 15 is fixedly connected to the side of the pressurized hot water storage tank 11, and a hot water outlet pipe 16 is installed at the bottom of the pressurized hot water storage tank 11.

[0035] In this embodiment, when the solar collector 12 is installed outdoors, the initial vertical angle and horizontal angle of the solar collector 12 during use are adjusted by the adjustment mechanism 2 according to the latitude of the area where it is used. The initial horizontal angle of the solar collector 12 is adjusted so that the initial installation angle of the solar collector 12 is within a suitable angle range when it is used in different areas.

[0036] After the overall installation is completed, cold water is introduced into the pressurized hot water storage tank 11 through the cold water inlet pipe 15. The cold water enters the collector 12 through the first connecting water pipe 13. After the collector 12 heats the cold water, the hot water automatically circulates back into the pressurized hot water storage tank 11 through the second connecting water pipe 14. When the collector 12 absorbs the heat energy of the sun outdoors, the angle of incidence of the sun on the surface of the collector 12 changes continuously as the sun rises in the east and sets in the west.

[0037] As the angle of sunlight changes, the vertical angle adjustment component in the adjustment mechanism 2 adjusts the vertical angle of the solar collector 12, and the horizontal angle adjustment component in the adjustment mechanism 2 adjusts the horizontal angle of the solar collector 12. According to the change of the angle of sunlight, the vertical and horizontal angles of the solar collector 12 are adjusted by the adjustment mechanism 2 so that the solar collector 12 can fully absorb and utilize solar energy.

[0040] In this embodiment, when the solar collector 12 is installed outdoors, according to the latitude of the area of ​​use, the first threaded sleeve 27 is rotated to move the first threaded support rod 28 up and down along the inside of the first threaded sleeve 27, so that the lower end of the solar collector 12 rotates along the third connecting frame 217, thereby adjusting the initial vertical angle of the solar collector 12 during use. Similarly, the second threaded sleeve 220 is rotated to adjust the extension length of the second connecting head 211, which drives the rack 228 to move. The rack 228 drives the gear 230 and the connecting shaft 231 to rotate, thereby adjusting the initial horizontal angle of the solar collector 12, so that the initial installation of the solar collector 12 is at a suitable angle.

[0041] When the water heater assembly 1 is initially used, the water inside the pressurized hot water storage tank 11 is difficult to boil and generates high-pressure gas. At this time, high-pressure air is supplied to the No. 5 gas supply pipe 515 by the air compressor 4. When it is necessary to adjust the vertical angle of the collector 12, the No. 5 control valve 516 is opened. At this time, the high-pressure air enters the No. 1 piston housing 29 through the No. 5 gas supply pipe 515 and the No. 4 gas supply pipe 513. The high-pressure gas pushes the No. 1 piston push rod 210 to move upward along the No. 1 piston housing 29, pushing the No. 2 connector 211, the No. 2 connector bracket 212 and the upper end of the collector 12. The vertical angle of the solar collector 12 is adjusted. When the horizontal angle of the solar collector 12 needs to be adjusted, the sixth control valve 518 is opened. High-pressure air enters the interior of the second piston housing 222 through the fifth air supply pipe 515 and the sixth air supply pipe 517. The second piston push rod 226 pushes the rack 228 to adjust the horizontal angle of the second connecting plate 22, thereby achieving the purpose of adjusting the horizontal angle of the solar collector 12. By adjusting the vertical and horizontal angles of the solar collector 12, the solar collector 12 can make full use of sunlight and improve the performance of the solar collector 12 in heating cold water.

[0042] During the heating process of cold water by the collector 12, when the hot water inside the pressurized hot water storage tank 11 is heated to boiling, the pressure inside the pressurized hot water storage tank 11 will gradually increase. At this time, the low-pressure gas storage tank 52 guides the high-pressure gas generated inside the pressurized hot water storage tank 11, and the high-pressure gas generated inside the pressurized hot water storage tank 11 is collected through the high-pressure gas storage tank 55. When the pressure inside the high-pressure gas storage tank 55 is too high, the first pressure relief valve 57 is opened, and the pressure in the high-pressure gas storage tank 55 is relieved through the third exhaust pipe 56. At the same time, the seventh control valve 59 is opened and the third control valve 54 is closed, and the pressure inside the pressurized hot water storage tank 11 is relieved through the fourth exhaust pipe 58, and the pressure in the high-pressure gas storage tank 55 is collected through the high-pressure gas storage tank 56. 5. The high-pressure gas generated by the water heater component 1 during operation is stored and utilized. When the angle of the collector 12 needs to be adjusted later, the fourth control valve 512 is opened. The high-pressure gas inside the high-pressure gas storage tank 55 first enters the fourth gas supply pipe 513 through the third gas supply pipe 511, and then enters the sixth gas supply pipe 517 through the fourth gas supply pipe 513. The high-pressure gas output from the fourth gas supply pipe 513 serves as the power source when the first piston push rod is lifted, and the high-pressure gas output from the sixth gas supply pipe 517 serves as the power source when the second piston push rod 226 is lifted. By using the high-pressure gas generated by solar heating water as a power source, the use of electrical energy is reduced, thereby making full use of solar energy.

[0043] After dark, control valve 215 is opened to discharge the high-pressure gas inside piston housing 29 through exhaust pipe 214, causing piston push rod 210 to reset. Similarly, control valve 224 is opened to reset piston push rod 226, thus resetting collector 12 to its initial position. When piston push rod 210 resets, spring 213 will restore its deformation and drive piston push rod 210 to reset. Similarly, spring 227 will pull piston push rod 226 to reset, thereby increasing the reset speed of collector 12 and ensuring that collector 12 is reset in an accurate position.

[0044] During the use of water heater component 1, when the high-pressure gas stored inside the high-pressure gas storage tank 55 is insufficient, the air compressor 4 can drive the adjustment mechanism 2 to operate, ensuring that the adjustment mechanism 2 has sufficient operating power and that the position of the collector 12 can be adjusted according to the angle of sunlight.

The second fixing frame 31 is fixedly connected to the bottom of the first connecting plate 21, and an installation insert plate 34 is fixedly connected to the side of the second fixing frame 31. An installation limiting plate 33 is fixedly connected to the side of the installation plate 32. The installation insert plate 34 is inserted into the installation limiting plate 33. A threaded adjusting rod 35 is threadedly connected to the bottom of the installation limiting plate 33. A support plate 36 is rotatably connected to the top of the threaded adjusting rod 35. The support plate 36 is in contact with the bottom of the installation insert plate 34. An arc-shaped slide rail 23 is fixedly connected to the upper part of the first connecting plate 21. An arc-shaped slider 24 is slidably connected inside the arc-shaped slide rail 23. The arc-shaped slider 24 is fixedly connected to the bottom of the second connecting plate 22. A limiting guide rail 232 is fixedly connected to the bottom of the first fixing frame 229. The upper part of the rack 228 is slidably connected to the limiting guide rail 232.

[0047] In this embodiment, when installing the solar collector 12 outdoors, the mounting plate 32 and the mounting limiting plate 33 are first fixed to the outdoor wall surface. Then, the adjusting mechanism 2 on the upper part of the second fixing frame 31 and the solar collector 12 are installed and fixed by inserting the mounting insert plate 34 into the mounting limiting plate 33. The height of the support plate 36 is adjusted by rotating the threaded adjusting rod 35, thereby adjusting the height of the mounting insert plate 34 and the second fixing frame 31. This prevents the installation height of the solar collector 12 from being too high or too low, which would cause the water inside the pressurized hot water storage tank 11 and the solar collector 12 to circulate during the process. When a blockage occurs, during the rotation of the second connecting plate 22 to adjust and reset the horizontal angle of the collector 12, the second connecting plate 22 will drive the arc-shaped slider 24 to slide along the arc-shaped slide rail 23. The arc-shaped slide rail 23 limits the rotation of the second connecting plate 22, improving the stability of the second connecting plate 22 during rotation. At the same time, the arc-shaped slider 24 supports the second connecting plate 22, improving the stability of the upper components of the second connecting plate 22 during use. The limiting guide rail 232 limits the movement of the rack 228, improving the stability of the rack 228 during movement.

[0048] The usage method and working principle of this device are as follows: When installing the solar collector 12 outdoors, first install and fix the mounting plate 32 and the mounting limiting plate 33 on the outdoor wall surface. Then, the mounting insert plate 34 is inserted into the mounting limiting plate 33 to install and fix the adjustment mechanism 2 on the upper part of the second fixing frame 31 and the solar collector 12. The height of the support plate 36 is adjusted by rotating the threaded adjustment rod 35, thereby adjusting the height of the mounting insert plate 34 and the second fixing frame 31.

[0049] By rotating the No. 1 threaded sleeve 27, the No. 1 threaded support rod 28 moves up and down along the inside of the No. 1 threaded sleeve 27, causing the lower end of the solar collector 12 to rotate along the No. 3 connecting frame 217, thereby adjusting the initial vertical angle of the solar collector 12 during use. The rack 228 drives the gear 230 and the connecting shaft 231 to rotate, thereby adjusting the initial horizontal angle of the solar collector 12.

[0050] Cold water enters the collector 12 through the first connecting water pipe 13. After the collector 12 heats the cold water, the hot water automatically circulates to the pressurized hot water storage tank 11 through the second connecting water pipe 14. When the collector 12 absorbs the heat energy of the sun outdoors, the angle of incidence of sunlight on the surface of the collector 12 is constantly changing. When the water heater component 1 is initially used, the water in the pressurized hot water storage tank 11 is difficult to reach boiling point and generate high-pressure gas. At this time, the air compressor 4 supplies high-pressure air to the fifth gas supply pipe 515 and opens the fifth control valve 516. At this time, the high-pressure air enters the first living water tank through the fifth gas supply pipe 515 and the fourth gas supply pipe 513. Inside the piston housing 29, high-pressure gas pushes the first piston push rod 210 upward along the first piston housing 29, pushing the second connector 211, the second connecting frame 212 and the upper end of the collector 12 to adjust the vertical angle of the collector 12. The sixth control valve 518 is opened, and high-pressure air enters the second piston housing 222 through the fifth air supply pipe 515 and the sixth air supply pipe 517. The second piston push rod 226 pushes the rack 228 to adjust the horizontal angle of the second connecting plate 22, thereby achieving the purpose of adjusting the horizontal angle of the collector 12. The vertical and horizontal angles of the collector 12 are adjusted.

[0051] During the heating process of cold water by the solar collector 12, when the hot water inside the pressurized hot water storage tank 11 is heated to boiling, the pressure inside the pressurized hot water storage tank 11 will gradually increase. The high-pressure gas generated by the pressurized hot water storage tank 11 is collected by the high-pressure gas storage tank 55. The high-pressure gas inside the high-pressure gas storage tank 55 first enters the fourth gas supply pipe 513 through the third gas supply pipe 511, and then enters the sixth gas supply pipe 517 through the fourth gas supply pipe 513. The high-pressure gas output from the fourth gas supply pipe 513 serves as the power source when the first piston push rod is lifted, and the high-pressure gas output from the sixth gas supply pipe 517 serves as the power source when the second piston push rod 226 is lifted. By using the high-pressure gas generated by solar heating of water as a power source, the use of electrical energy is reduced, thereby making full use of solar energy.

[0052] Opening control valve 215 discharges the high-pressure gas inside piston housing 29 through exhaust pipe 214, causing piston push rod 210 to reset. Similarly, opening control valve 224 resets piston push rod 226, thus resetting collector 12 to its initial position. When piston push rod 210 resets, spring 213 will restore its deformation and drive piston push rod 210 to reset. Similarly, spring 227 will pull piston push rod 226 to reset.

[0053] When the second connecting plate 22 rotates to adjust and reset the horizontal angle of the collector 12, the second connecting plate 22 will drive the arc-shaped slider 24 to slide along the arc-shaped slide rail 23. The arc-shaped slide rail 23 limits the rotation of the second connecting plate 22, while the arc-shaped slider 24 supports the second connecting plate 22. The movement of the rack 228 is limited by the limiting guide rail 232.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
