Description

Technical Field

[0001] The utility model relates to the technical field of solar energy equipment, and particularly relates to a solar tracking device for a campus hot water system. Background Technique

[0002] In the existing campus hot water system, solar collectors are usually installed in a fixed manner, which means they are installed at a fixed angle and direction and cannot be adjusted as the position of the sun changes. This fixed installation method has a major problem: the solar collectors cannot always face the sun, especially when the position of the sun changes with seasons and different times of the day. Therefore, the absorption efficiency of solar energy is not optimal, resulting in low energy utilization efficiency of the hot water system.

[0003] In addition, since the solar collectors cannot automatically track the sun, it is necessary to manually adjust their angles regularly to maximize the absorption of solar energy, which not only increases the maintenance cost but also reduces the automation level of the system. Under bad weather conditions, the fixed solar collectors may not be able to maintain stability, affecting the overall performance and service life of the system.

[0004] To overcome these drawbacks, various solar tracking systems have been tried. These systems generally include sensors, control units and drive mechanisms for automatically adjusting the direction of the solar collectors according to the position of the sun. However, these systems may be complex in structure, costly, and require additional maintenance and adjustment in specific environments such as campuses. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0018] Please refer to Figures 1-3 , the present invention provides a technical solution: a solar tracking device for a campus hot water system, which is mainly composed of a bearing plate 1. The bearing plate 1 serves as the foundation of the entire device, and its design must be strong enough to support all components. The lower part of the bearing plate 1 is provided with a motor fixing bracket 2, and a driving motor 3 is arranged below the motor fixing bracket 2. The output end of the driving motor 3 is connected to the rotating shaft 4, enabling the normal operation of the entire device.

[0019] Inside the wall of the bearing plate 1, a first pedestal bearing 5 and a second pedestal bearing 6 are respectively arranged. The rotating shaft 4 passes through the bearing hole of the first pedestal bearing 5, and a driven shaft 7 is installed on the second pedestal bearing 6. A driving pulley 8 is installed on the rotating shaft 4, and a driven pulley 9 is equipped on the driven shaft 7. The driving pulley 8 and the driven pulley 9 are tightly connected by a synchronous toothed belt 10, ensuring the accuracy of transmission.

[0020] The upper part of the rotating shaft 4 is fixed with a first fixing seat 11, and the upper part of the driven shaft 7 is fixed with a second fixing seat 12. A solar collector 13 is installed on the first fixing seat 11 for absorbing solar energy and converting it into heat energy. A photosensitive sensor 14 is installed on the second fixing seat 12 for detecting the intensity and direction of sunlight. The photosensitive sensor 14 can monitor the position change of the sun in real time and transmit the data to the microprocessor 15.

[0021] A microprocessor 15 is installed on the lower side of the carrier plate 1. The microprocessor 15 is electrically connected to the photosensitive sensor 14 and the drive motor 3. The microprocessor 15 controls the operation of the drive motor 3 according to the detection signal provided by the photosensitive sensor 14, thereby achieving precise tracking of the solar tracking device. The microprocessor 15 can process the data of the photosensitive sensor 14 and adjust the operating state of the drive motor 3 according to these data to ensure that the solar collector 13 always faces the sun.

[0022] To enhance the stability and reliability of the device, a support rod 16 is also installed on the lower end part of the carrier plate 1. The lower end part of the support rod 16 is fixed with a mounting seat 17. The mounting seat 17 is provided with a number of threaded holes and connecting bolts for firmly mounting the device on the ground.

By adjusting the adjustment screw block 18, the tension of the synchronous toothed belt 10 can be easily adjusted, thereby ensuring the high efficiency and stability of the belt drive system.

[0024] Finally, in order to ensure that the transmission between the drive motor 3 and the rotating shaft 4 is smoother and more efficient, a coupling is specially provided between the drive motor 3 and the rotating shaft 4 to reduce vibration and impact during transmission. The coupling can absorb and compensate for axial and radial deviations caused by load changes or misalignment, thereby protecting the motor and the rotating shaft from damage and extending the service life of the entire device.

[0027] A solar collector 13 is installed on the first fixing base 11 for absorbing solar energy. A photosensitive sensor 14 is installed on the second fixing base 12 for detecting the direction and intensity of sunlight.

[0028] A microprocessor 15 is provided on the lower side of the carrier plate 1. The microprocessor 15 is electrically connected to the photosensitive sensor 14 and the drive motor 3. The microprocessor 15 controls the start and stop of the drive motor 3, as well as the rotation direction and speed of the rotating shaft 4 according to the detection signal of the photosensitive sensor 14, so as to realize the automatic tracking of the solar collector 13.

[0029] Support rods 16 are provided at the lower end of the carrier plate 1. Mounting seats 17 are provided at the lower ends of the support rods 16. The mounting seats 17 are fixed to the ground through threaded holes and connecting bolts to increase the stability of the entire device.

[0030] Adjusting screw blocks 18 are provided on the carrier plate 1. Adjusting bolts 19 are inserted into the holes of the adjusting screw blocks 18. Idler wheels 20 are provided at the ends of the adjusting bolts 19.
