Description

Technical Field

[0001] The present invention relates to the technical field of solar energy equipment, in particular to a solar water heater. Background Art

[0002] Solar energy is a renewable energy source. It refers to the sun's thermal radiation, primarily manifested as sunlight. Modern solar thermal technology concentrates sunlight and harnesses its energy to produce hot water, steam, and electricity. In addition to using appropriate technology to capture solar energy, buildings can also harness the sun's light and heat by incorporating appropriate design features, such as large south-facing windows or using building materials that absorb and slowly release the sun's heat.

[0003] Existing solar water heaters generally use circular heat collecting tubes, which are arranged uniformly in the horizontal direction. As a result, only the upper surface of the heat collecting tubes can be illuminated, while the lower surface cannot be illuminated. Moreover, when the heat collecting tubes are arranged uniformly in the horizontal direction, there is a gap between adjacent tubes, resulting in uneven heating and low light-collecting efficiency in traditional solar water heaters. Therefore, the present invention proposes a solar water heater system with uniform heating and high light-collecting efficiency. Summary of the Invention

[0004] The main purpose of the invention is to provide a solar water heater to effectively solve the problems of uneven heating and low daylighting rate of existing solar water heaters.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted by the invention is:

[0006] A solar water heater includes a water tank, the lower end of the water tank is fixedly connected to a bracket, a rear mounting seat is fixed on the bracket, a front mounting seat is fixed on the water tank, a plurality of heat collecting tubes are fixed between the front mounting seat and the rear mounting seat, a photovoltaic panel assembly is fixed on the back of the heat collecting tube on the water tank, and the photovoltaic panel assembly is electrically connected to an energy storage box.

[0007] Preferably, the front mounting seat includes an annular shell, a T-shaped plate is provided in the middle of the annular shell, the T-shaped plate is fixedly connected to the inner wall of the water tank, the T-shaped plate and the annular shell form an annular groove in which a plurality of No. 1 gears are provided, a through hole is provided in the middle of the No. 1 gear, the through hole is connected to the heat collecting pipe, a safety door is provided on the side of the No. 1 gear close to the water tank, and a sealing ring is provided on the side of the No. 1 gear away from the water tank, and the heat collecting pipe passes through the sealing ring and is fixedly connected to the rear mounting seat.

[0008] Preferably, the safety door includes a movable door, which is hinged in a through hole in the middle of the No. 1 gear, and the movable door is connected to the float via a pull wire.

[0009] Preferably, the front mounting seat further includes a gear ring, the gear ring is fixedly connected to the annular housing, and the gear ring is meshed with the number one gear.

[0010] Preferably, the structure of the rear mounting seat is the same as that of the front mounting seat, except that a motor box is provided at the top of the rear mounting seat, a motor is fixed in the motor box, the output end of the motor is driven by meshing with the double-sided gear ring through the No. 2 gear, the inner diameter of the double-sided gear ring is the same as the inner diameter of the gear ring, the teeth on the other side of the double-sided gear ring are meshed with multiple No. 3 gears, and the No. 3 gear is fixedly connected to the heat collecting pipe.

[0026] As a specific embodiment of the present invention, the safety door 34 includes a movable door 341, which is hinged in the through hole in the middle of the No. 1 gear 33. The movable door 341 is connected to the float 342 through a pull wire. When the water heater is working normally, the float 342 provides tension to the movable door 341 through buoyancy, so that the movable door 341 is in a normally open state. When the heat collecting tube 5 explodes, the water flows toward the exploded tube, and the water pressure will press the movable door 341 to prevent the hot water in the water tank 1 from flowing out, paralyzing the entire device. By setting the safety door 34, the present invention can promptly prevent the hot water in the water tank 1 from flowing out from the exploded tube when the heat collecting tube 5 explodes due to uncontrolled conditions.

[0027] As a specific embodiment of the present invention, the front mounting seat 3 further includes a gear ring 36 , which is fixedly connected to the annular housing 31 and meshes with the first gear 33 .

[0028] As a specific embodiment of the present invention, the rear mounting seat 4 has the same structure as the front mounting seat 3, except that a motor box 41 is provided at the top of the rear mounting seat 4, and a motor 42 is fixed in the motor box 41.

[0029] In the present invention, the motor 42 drives the double-sided gear ring 37 to rotate, and then drives the third gear 44 to rotate around the double-sided gear ring 37. Driven by the third gear 44, the first gear 33 also rotates around the gear ring 36, so that the heat collecting tube 5 revolves around the double-sided gear ring 37 while also rotating, so that the heat collecting tube 5 is heated more evenly.

[0030] As a specific implementation of the present invention, the number of the first gear 33 and the third gear 44 is the same as the number of the heat collecting tubes 5 .

[0033] When in use, the energy storage box transmits the electric energy converted by the photovoltaic panel assembly 6 to the motor 42, and the motor 42 drives the double-sided gear ring 37 to rotate, and then drives the third gear 44 to rotate around the double-sided gear ring 37. Driven by the third gear 44, the first gear 33 also rotates around the gear ring 36, so that the heat collecting tube 5 revolves around the double-sided gear ring 37 while rotating on its own, so that the heat collecting tube 5 is heated more evenly and the heating efficiency is improved; when the heat collecting tube 5 explodes uncontrollably, due to the water flowing to the exploded tube, the water pressure will press the movable door 341 to prevent the hot water in the water tank 1 from flowing out, paralyzing the entire device.
