Technical Field

[0001] The present invention relates to the technical field of solar energy utilization, and specifically to a protective solar heat collecting tube assembly. Background Art

[0002] With the increasing global demand for renewable energy, solar energy, as a clean and renewable energy source, has received extensive attention in terms of its utilization efficiency and cost-effectiveness. Solar heat collecting tube technology has become a research and application hotspot due to its high thermal conversion efficiency. Traditional solar heat collecting tube systems usually include main components such as heat absorption tubes, reflector plates, and thermal insulation shells. They convert solar radiation into heat energy and transfer it to working media such as water or other liquids for heating or power generation.

[0003] However, there are some defects and deficiencies in the existing solar heat collecting tube systems. First, the accumulation of dirt and scale on the surface of traditional heat collecting tubes will significantly reduce the photothermal conversion efficiency, requiring regular cleaning, which increases the maintenance cost and labor intensity. Second, most heat collecting tube systems lack effective protection mechanisms and are easily affected by the external environment, such as being damaged by natural conditions like wind, rain, and snow. This may damage the structural integrity and functional performance of the heat collecting tubes and shorten their service life. In addition, the existing solar heat collecting tube systems are usually fixedly installed and cannot automatically adjust the angle to track the movement trajectory of the sun, resulting in the inability to maximize the capture and utilization of available solar radiation, reducing the energy collection efficiency, and also unable to discharge or inhale part of the water in the device according to the intensity of solar radiation to improve the photothermal conversion efficiency of the device.

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

The protection assembly further includes a driving assembly and a cleaning assembly; A detection mechanism is arranged on the bracket 1 and is used for detecting the intensity of solar radiation; A touch assembly is arranged on the pallet 3 and is used for turning on or off the protection mechanism.

[0019] As a preferred implementation manner in this embodiment, please refer to Figure 1 , Figure 2 , Figure 4 ,Figure 5 , Figure 6 , Figure 7 As shown in Figure 10 , the driving assembly includes: a limiting rod 11, which is fixedly installed between two fixing rings 6 and penetrates through the outer magnetic ring 9. A threaded rod 12 is rotatably connected below the limiting rod 11 between the two fixing rings 6. A circular groove 13 is formed in the side wall of one of the fixing rings 6, and a motor 14 is fixedly installed inside the circular groove 13. The output shaft of the motor 14 is connected to one end of the threaded rod 12.

[0021] According to the above characteristics, while protecting the ultraviolet glass tube 4, the outer surface of the ultraviolet glass tube 4 and the inner surface of the high-temperature resistant glass tube 5 can be cleaned.

When the corrugated pipe 10 is closed, it can play a role in heat preservation and protection for the ultraviolet glass tube 4. When the motor 14 rotates in reverse, the outer magnetic ring 9 will descend, allowing the ultraviolet glass tube 4 to fully receive solar radiation.

[0025] According to the above characteristics, the external placement of the ultraviolet glass tube 4 can be adjusted according to the intensity of solar radiation, and at the same time, the motor 14 can be automatically started. Specifically, the solar radiation monitor 20 monitors the intensity of the sun and transmits the data to the signal processing circuit 22, and then controls the start of the four electric push rods 27 through the microcontroller 23 and the drive circuit 24, so that the ultraviolet glass tube 4 follows the movement track of the sun for adjustment. When the sun sets, the horizontal plate 28 will tilt to the leftmost side, so that the moving block 30 inside the horizontal plate 28 moves to the leftmost side on the moving bin 29 and presses the closing switch 31, so that the motor 14 is automatically started to lift the corrugated pipe 10 to protect the ultraviolet glass tube 4. When the sun appears, the horizontal plate 28 will tilt to the rightmost side, so that the moving block 30 presses the unfolding switch 32, so that the motor 14 rotates in reverse to lower the corrugated pipe 10, so that the ultraviolet glass tube 4 can fully receive solar radiation.

[0026] As a preferred implementation manner in this embodiment, please refer to Figures 1 to 3 As shown, a storage tank 33 is fixedly installed on the rear side wall of the bracket 1. A communicating pipe 34 is arranged on the top surface of the storage tank 33. The communicating pipe 34 communicates the inside of the water tank 2 with the inside of the storage tank 33. A water pump 35 is fixedly installed on the rear side wall of the storage tank 33.

[0027] According to the above characteristics, part of the water in the high-temperature resistant glass tube 5 can be discharged according to the intensity of solar radiation, improving the heating efficiency. Specifically, start the motor 14, so that the cleaning plate 16 collects part of the water inside the high-temperature resistant glass tube 5 into the storage tank 33 through the communicating pipe 34, reducing the amount of water, which can improve the heating efficiency of the water in the water tank 2 and the high-temperature resistant glass tube 5. When the solar radiation monitor 20 detects high solar radiation, the solar panel 25 will start to re-inject the water in the storage tank 33 into the inside of the water tank 2 through the water suction pipe 36 and the water outlet pipe 37.

[0028] Working principle: In use, a protection mechanism disposed outside the ultraviolet glass tube 4, including components such as a fixing ring 6, a connecting block 7, a refracting plate 8, an outer magnetic ring 9, and a corrugated pipe 10, is used to protect and clean the ultraviolet glass tube 4. When the motor 14 is started, it drives the threaded rod 12 to rotate, causing the outer magnetic ring 9 to slide upward along the outer surface of the ultraviolet glass tube 4. At the same time, it drives the inner magnetic ring 15 and the cleaning plate 16 to move, thereby cleaning the dirt and scale on the outer surface of the ultraviolet glass tube 4 and the inner surface of the high-temperature-resistant glass tube 5. The corrugated pipe 10 unfolds or contracts as the outer magnetic ring 9 moves, providing protection for the ultraviolet glass tube 4 and playing a heat preservation role when closed. The detection mechanism includes components such as a support block 17, a fixing rod 18, and a solar radiation monitor 20, which are responsible for capturing and measuring the solar radiation intensity. The signal processing circuit 22 processes the monitoring data and controls the operation of the electric push rod 27 through the microcontroller 23 and the drive circuit 24 to automatically adjust the angle of the ultraviolet glass tube 4 to follow the movement trajectory of the sun and optimize the light and heat reception efficiency. The touch component is composed of a horizontal plate 28, a moving bin 29, a moving block 30, a closing switch 31, and an unfolding switch 32. It uses the inclination change of the horizontal plate 28 to control the start and reverse rotation of the motor 14, realizing the automatic lifting of the corrugated pipe 10, protecting the ultraviolet glass tube 4 from the environmental impact during non-working hours, and maximizing the solar radiation reception during the day. The storage tank 33, the connecting pipe 34, the water pump 35, its suction pipe 36, and the outlet pipe 37 installed at the rear of the bracket 1 constitute a water temperature adjustment system. According to the solar radiation intensity, part of the water in the high-temperature-resistant glass tube 5 can be transferred to the storage tank 33 by starting the motor 14 to reduce the water volume and improve the heating efficiency. When the solar radiation is strong, the solar panel 25 can start the water pump 35 to re-inject the stored water into the water tank 2 through the suction pipe 36 and the outlet pipe 37 to maintain the ideal working temperature.
