Description

Technical Field

[0001] The invention relates to the field of water heaters, and in particular to an energy-saving solar water heater. Background Art

[0002] A solar water heater is a device that uses solar energy to heat water. Solar water heaters mainly rely on collectors to absorb solar energy. Collectors are usually composed of vacuum tubes or flat plate collectors. The vacuum tubes of vacuum tube collectors have a special coating that can efficiently absorb solar radiation energy and convert it into heat energy to heat the water in the tubes. Flat plate collectors absorb solar energy through heat absorbing plates and then transfer heat to the water flowing through them. Due to the principle of thermal expansion and contraction, the heated water becomes less dense and rises into the water tank. The cold water in the water tank will be added to the collector, forming a natural cycle, so that the water in the entire water tank gradually heats up.

[0003] For example, the patent application number 201520773148.9 discloses a self-circulating solar water heater, including a collector and a circulating water tank, the top of the collector is connected to the upper part of the side wall of the circulating water tank through an upper circulating pipe, and the bottom of the collector is connected to the bottom of the circulating water tank through a lower circulating pipe; the circulating water tank is connected to a supply water tank for providing cold water to the circulating water tank and a water storage tank for users to use hot water through a pipeline, a solenoid valve is provided on the pipeline between the circulating water tank and the water storage tank, a thermometer is built into the circulating water tank, and the thermometer and the solenoid valve are connected to a PLC controller through wired or wireless connection. The utility model has a simple structure, reasonable design, automatic circulation, rapid heating, energy saving and environmental protection, high degree of automation, can solve the problem of dry burning of the collector due to lack of water supply in the circulating water tank, and improve the practical life of the solar water heater.

[0004] Patent application number 93234362.7 discloses a household solar water heater with automatic temperature control, which is composed of a collector, a water storage tank, a bracket, and an electric heating auxiliary device. The water circulation pipeline of the entire system runs longitudinally through the interior of the collector, and then the input and output ends of the collector's pipeline are directly connected to the water tank. The utility model has high solar energy utilization efficiency, and the water temperature can be maintained within a certain temperature range at ordinary times. It is suitable for use by several people in a family and can be used at any time and in any climate. Another advantage is that the system is compact in structure, small in size, light in weight, and movable.

[0005] However, the above-mentioned solar water heaters and similar solar water heaters are generally fixedly installed, and the sun can directly shine on the collector for only a few hours a day, resulting in insufficient heat absorption efficiency of the solar water heater, which is more obvious in winter and needs to be improved.

[0026] Example 1

[0027] like Figure 1-4 As shown, an energy-saving solar water heater is characterized in that it includes a base 3, a lower support column 16 is fixedly provided at the center of the top surface of the base 3, a mounting plate 18 is fixedly provided on the top of the lower support column 16, the top of the mounting plate 18 is fixedly connected to the inner ring of the bearing 14, the outer ring of the bearing 14 is fixedly connected to the bottom end of the upper support column 2, a collector fixing plate 1 is fixedly provided on the top of the upper support column 2, the collector fixing plate 1 is inclined, and the collector fixing plate 1 is used to install the solar collector.

[0028] A circular guide groove 13 is provided in the center of the top surface of the base 3 , and the circular guide groove 13 is located outside the bearing 14 . L-shaped brackets 19 are fixedly provided on both the front and rear sides of the upper support column 2 , and the lower end of the L-shaped bracket 19 is fixedly connected to the arc-shaped guide block 15 , and the arc-shaped guide block 15 is located in the circular guide groove 13 .

[0029] When in use, the upper support column 2 is rotated according to the position of the sun, so that the upper support column 2 drives the collector fixing plate 1 to rotate, thereby adjusting the position of the solar collector on the collector fixing plate 1, so that sunlight can directly hit the solar collector and improve the heat absorption efficiency.

[0030] Example 2

[0031] like Figure 1-4As shown, when other parts are the same as those of the first embodiment, the difference between the present embodiment and the first embodiment is that: a convex lens 17 is fixedly arranged in the center of the mounting plate 18, a plurality of light-sensitive triggering mechanisms 12 are arranged on the right side of the bearing 14, and the plurality of light-sensitive triggering mechanisms 12 are arranged around the bearing 14. A battery 9 is arranged on the side of the light-sensitive triggering mechanism 12 away from the bearing 14, and the battery 9 is fixedly connected to the base 3. A motor 8 is fixedly arranged on the top of the battery 9. The positive electrode of the battery 9 is connected to the motor 8 through the positive electrode wire 5, and the negative electrode of the battery 9 is connected to the light-sensitive triggering mechanism 12 through the first negative electrode wire 11. The light-sensitive triggering mechanism 12 is connected to the motor 8 through the second negative electrode wire 10. The power output end of the motor 8 is fixedly connected to the rotating shaft 7, and the rotating shaft 7 is fixedly connected to one end of the connecting rope 4, and the connecting rope 4 is wound on the rotating shaft 7. A connecting rod 20 is fixedly arranged on the right side of the bottom end of the upper support column 2, and the other end of the connecting rope 4 is fixedly connected to the connecting rod 20. The front and rear ends of the rotating shaft 7 are fixedly sleeved with a limit plate 6.

[0032] The light-sensitive trigger mechanism includes a plurality of glass outer tubes 21, which are connected end to end to form a long tube shape. Two adjacent glass outer tubes 21 are fixedly connected by an isolation plate 24. An upper conductive plate 25 is fixedly arranged inside the glass outer tube 21. A lower conductive plate 26 is arranged below the upper conductive plate 25. The bottom of the lower conductive plate 26 is fixedly connected to a piston 27. The piston 27 is slidably connected to a glass inner tube 28. Water is arranged inside the glass inner tube 28. The bottom end of the glass inner tube 28 is fixedly connected to the bottom of the glass outer tube 21. The lower conductive plate 26 is fixedly connected to one end of the first connecting wire 23. The other end of the first connecting wire 23 penetrates the glass outer tube 21 and is connected to the first negative electrode wire 11. The upper conductive plate 25 is fixedly connected to one end of the second connecting wire 22. The other end of the second connecting wire 22 penetrates the glass outer tube 21 and is connected to the second negative electrode wire 10. The outer wall of the glass inner tube 28 is coated with a heat-absorbing coating.

[0033] In the morning, the sun rises from the east, and the sun shines on the convex lens 17 from the east. The convex lens 17 focuses the light on the west side of the base 3. As the sun continues to rise, the sun moves from east to west, and the light spot formed by the convex lens 17 moves from west to east.

[0034] When the light spot formed by the convex lens 17 focuses light and irradiates any glass outer tube 21 of the light-sensitive trigger mechanism 12 on the westernmost side, the heat-absorbing coating on the glass inner tube 28 inside the glass outer tube 21 absorbs heat, causing the water inside the glass inner tube 28 to evaporate into water vapor to lift the piston 27, and the piston 27 drives the lower conductive plate 26 to move up synchronously and contact the upper conductive plate 25. At this time, the battery 9, the first negative electrode wire 11, the first connecting wire 23, the lower conductive plate 26, the upper conductive plate 25, the second connecting wire 22, the second negative electrode wire 10, and the motor 8 are connected in sequence to form a loop. The battery 9 supplies power to the motor 8 to start the motor 8, and the motor 8 drives the rotating shaft 7 to rotate and wind the connecting rope 4, and the connecting rope 4 drives the connecting rod 20 to rotate counterclockwise (because the remaining motors 8 are not started, the connecting ropes 4 connected to these motors 8 can move freely to cooperate with the rotation of the connecting rod 20) until the connecting rope 4 and the connecting rod 20 are in a straight line. When the connecting rod 20 rotates counterclockwise, it drives the upper support column 2 and the collector fixing plate 1 to rotate counterclockwise synchronously, so that the collector fixing plate 1 faces the sun in the east, and the sunlight can directly irradiate the solar collector on the collector fixing plate 1.

[0035] As the sun moves from east to west, the light spot formed by the convex lens 17 moves from west to east. When the light spot does not irradiate the light-sensitive trigger mechanism 12, the water vapor cools down and turns back into water. The piston 27 drives the lower conductive plate 26 to descend, so that the lower conductive plate 26 is separated from the upper conductive plate 25, thereby cutting off the power to the motor 8 and stopping.

[0036] The light spot formed by the convex lens 17 gradually moves to illuminate the next light-sensing trigger mechanism 12, so that the motor 8 on the same side of the light-sensing trigger mechanism 12 is started, and the motor 8 drives the rotating shaft 7 to rotate and wind the connecting rope 4, and drives the connecting rod 20, the upper support column 2, and the collector fixing plate 1 to rotate clockwise through the connecting rope 4, so as to adjust the position of the collector fixing plate 1 so that the collector fixing plate 1 faces the sun again, and the sunlight can directly irradiate the solar collector on the collector fixing plate 1.

[0037] As the sun moves westward, the connecting rod 20, the upper support column 2, and the collector fixing plate 1 are continuously rotated clockwise to adjust their positions, so that the collector fixing plate 1 always faces the sun, and the sunlight can always directly irradiate the solar collector on the collector fixing plate 1.

[0038] Example 3

[0039] like Figure 1 As shown, when other parts are the same as those of Example 2, the difference between this embodiment and Example 2 is that a transparent protective cover 29 is sleeved on the outer side of the upper support column 2, the protective cover 29 is located above the base 3, and a connecting ring 31 is fixedly sleeved on the bottom of the protective cover 29, and the connecting ring 31 is connected to the base 3 through a plurality of connecting screws 30. The protective cover 29 covers the motor 8, the battery 2 and other parts, which can effectively protect these parts.

It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
