For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0038] As mentioned in the background technology, with the intensification of the global energy crisis and the improvement of environmental protection awareness, traditional heating methods based on fossil fuels are facing severe challenges. These traditional heating systems not only consume a large amount of non-renewable resources, but also produce a large amount of greenhouse gases and other pollutants during use, which impose a serious burden on the environment. Therefore, the development and application of new clean energy heating technologies has become an important issue in today's society. As an endless renewable energy source, solar energy has great application potential in the field of heating. However, traditional solar heating systems often have problems such as low efficiency, poor stability, and low intelligence, which limits their widespread application in practice. In order to overcome these shortcomings and improve the practicality and economy of solar heating systems, it is necessary to develop a more efficient, stable and intelligent solar thermal heating system.

[0039] To improve the above problems, the present application proposes a solar-based heat collection and heating system and method. By setting up multiple heat collection components, the system can capture solar radiation energy more widely. Each component works independently, but is interconnected to form an efficient whole to maximize energy collection. Advanced heat exchanger technology is used to ensure that the heat energy collected from the heat collection component can be efficiently transferred to the heating area, reducing the loss of energy during transmission. The system mainly relies on solar energy for heating, reducing the demand for traditional fossil fuels such as coal and oil, thereby reducing the consumption rate of these resources. The integrated temperature detector and control module can adjust the working state of the heat collection component according to the real-time ambient temperature to ensure that a stable heating effect can be provided under different climatic conditions.

The heat collection components set in a rectangular array can be increased or decreased according to actual needs, which is convenient for the expansion or maintenance of the system. According to different building structures and heating needs, the number and layout of the heat collection components can be flexibly configured to adapt to various scenarios. By adjusting the position of the focusing plate through the electric rotating shaft, the heat collection efficiency of the vacuum collector tube can be effectively increased, further improving the heat collection capacity of the entire system. The precise control of the focusing plate enables the system to dynamically adjust according to the angle and intensity of the sun, ensuring that it always works at the highest efficiency. The design of the support frame, support assembly and focusing assembly takes into account the stability and durability of the structure, while ensuring the effective operation of the heat collection assembly.

[0041] A solar energy-based heat collection and heating system according to an embodiment of the present application includes:

[0042] A heat collecting assembly, wherein a plurality of heat collecting assemblies are provided, the bottoms of the plurality of heat collecting assemblies are fixedly connected to the ground, and the plurality of heat collecting assemblies are connected and communicated with each other;

[0043] The heat exchanger 1 has one end connected to a plurality of heat collecting components, and the other end connected to a heating area 12. The heat exchanger 1 is provided with a temperature detector and a control module.

[0044] In some specific embodiments, a plurality of heat collection components are arranged in a rectangular array.

[0045] Specifically, multiple heat collection components can be provided according to actual conditions.

[0046] In some specific embodiments, two adjacent heat collecting assemblies are connected via a pipeline 2 .

[0047] In some specific embodiments, the heat collection assembly includes:

[0048] A support frame 3, with a support seat 4 disposed at the bottom of the support frame 3;

[0049] A supporting component is provided on the top of the support frame 3;

[0050] The vacuum heat collecting tube 5 is arranged on the top of the supporting assembly, and the bottom of the vacuum heat collecting tube 5 abuts against the top of the supporting assembly;

[0051] The focusing assembly is arranged above the vacuum heat collecting tube 5, and both ends of the focusing assembly are fixedly connected to the top of the support frame 3 respectively.

[0052] In some specific embodiments, the diameter of the support frame 3 is larger than the diameter of the vacuum heat collecting tube 5 , and a plurality of support seats 4 are arranged at intervals.

[0053] In some specific embodiments, the top of the support seat 4 is fixedly connected to the bottom of the support frame 3 , the axial cross-section of the bottom of the support seat 4 is a trapezoidal structure, and a threaded hole 6 is provided at the bottom of the support seat 4 .

[0054] Specifically, through the threaded hole 6 on the support base 4, a bolt can pass through the threaded hole 6 and the threaded hole on the ground so that the support base 4 is fixedly connected to the ground.

[0055] Through the configuration of multiple collector components, the system can maximize the capture and conversion of solar energy into thermal energy, thereby improving the overall energy efficiency. This design is particularly suitable for areas with abundant sunshine and can significantly reduce dependence on traditional fossil fuels. The rectangular array setting and interconnectivity of the collector components allow the system to be easily expanded or reduced in size according to actual needs. This modular design is not only easy to install and maintain, but also makes the system more flexible and can adapt to installation spaces of different sizes and shapes. The heat exchanger in the system uses efficient heat conduction materials and technologies to ensure that the heat collected from the collector components can be effectively transferred to the heating area. The addition of temperature detectors and control modules can achieve precise control of the heating temperature and improve the response speed and energy efficiency of the system. The design of the support frame and support seat enhances the structural stability of the entire system, allowing it to maintain stable operation even in severe weather conditions. In addition, the combination of focusing components and vacuum collector tubes improves the durability and anti-aging ability of the system. Using solar energy as the main energy source, the system reduces the emission of greenhouse gases and other pollutants, contributing to environmental protection and sustainable development. At the same time, solar energy is a renewable energy source, which means that the system can operate for a long time without depleting natural resources.

[0056] In some specific embodiments, the support assembly includes:

[0057] A connecting column 7, wherein two connecting columns 7 are symmetrically arranged with the axis of the support frame 3 as the axis, and the two connecting columns 7 are respectively fixedly connected to the inner side wall of the support frame 3;

[0058] The support plate 8 is arranged horizontally, and the two sides of the support plate 8 are respectively fixedly connected to the two connecting columns 7, and the top of the support plate 8 matches the bonding surface of the bottom of the vacuum heat collecting tube 5, so that they can be abutted and bonded;

[0059] The rubber pad 9 is arranged on the top of the support plate 8 , the bottom of the rubber pad 9 is bonded and connected to the top of the support plate 8 , and the top of the rubber pad 9 is in contact with the bottom of the vacuum heat collecting tube 5 .

[0060] Specifically, a support plate 8 is provided at the bottom of the vacuum heat collecting tube 5 , and a rubber pad 9 is provided on the top of the support plate 8 . The rubber 9 can play a role of buffering and supporting the vacuum heat collecting tube 5 .

[0061] By the fixed connection between the connecting column 7 and the inner wall of the support frame 3, and the fixed connection between the two sides of the support plate 8 and the connecting column 7, a stable support structure is formed to ensure that the vacuum heat collection tube 5 remains stable during operation and reduce displacement or damage caused by factors such as vibration or wind. The rubber pad 9 is set on the top of the support plate 8 to provide an additional buffer layer for the vacuum heat collection tube 5. This buffer layer can absorb the impact and vibration caused by temperature changes, wind or mechanical vibration, thereby protecting the vacuum heat collection tube 5 from damage and extending its service life. The top of the support plate 8 matches the shape of the fitting surface at the bottom of the vacuum heat collection tube 5, and can be abutted and fitted. Such a design helps to maximize the heat transfer efficiency. The use of the rubber pad 9 not only provides a buffer, but also fills possible tiny gaps, further ensuring the effective transfer of heat energy. The presence of the rubber pad 9 prevents the vacuum heat collection tube 5 from directly contacting the hard support plate, reduces scratches or other forms of damage that may be caused by hard contact, and protects the integrity and functionality of the heat collection tube. The design of the support assembly takes into account the convenience of installation and maintenance. The fixed connection between the connecting column and the support plate simplifies the installation process, and the application of the rubber pad 9 also makes future maintenance and replacement work easier. This design allows the system to adapt to uneven ground or other installation environment variations to a certain extent, because the rubber pad 9 has a certain deformation capacity and can maintain effective support and buffering under different conditions.

[0062] In some specific embodiments, the focusing component includes:

[0063] An electric rotating shaft 10, wherein two electric rotating shafts 10 are symmetrically arranged with the axis of the support frame 3 as the axis, and the mounting ends of the two electric rotating shafts 10 are respectively fixedly connected to the two sides of the top of the support frame 3, and the two electric rotating shafts 10 are arranged horizontally;

[0064] The focusing plate 11 is arranged in parallel with the vacuum heat collecting tube 5 , and both ends of the focusing plate 11 are fixedly connected to the rotating ends of the two electric rotating shafts 10 .

[0065] Specifically, the rotation of the electric rotating shaft 10 can drive the focusing plate 11 to rotate, thereby adjusting the angle of the focusing plate 11, thereby changing the position where the sunlight is focused on the vacuum heat collecting tube 5. The focusing plate 11 can be a Fresnel lens.

[0066] In some specific embodiments, two adjacent vacuum heat collecting tubes 5 are connected via the pipeline 2 , and a plurality of vacuum heat collecting tubes 5 are connected to the heat exchanger 1 via the pipeline 2 .

[0067] Specifically, the focusing plate 11 is driven to rotate by the electric rotating shaft 10, so that the focusing position of sunlight on the vacuum heat collecting tube 5 can be adjusted. This adjustment capability ensures that sunlight always shines on the heat collecting tube 5 at the best angle, maximizing the efficiency of solar energy collection and conversion. If the focusing plate 11 adopts a Fresnel lens, it can further concentrate sunlight and enhance the light intensity, thereby improving the heat absorption efficiency of the heat collecting tube. The design of the electric rotating shaft 10 allows the angle of the focusing plate 11 to be dynamically adjusted according to the position of the sun, so that the system can operate efficiently at different times and seasons. By automatically or manually adjusting the angle of the focusing plate 11, the system can adapt to different solar altitude angles from sunrise to sunset, ensuring continuous and efficient energy collection. Multiple vacuum heat collecting tubes 5 are connected through pipelines. Even if a heat collecting tube fails or its efficiency decreases, other heat collecting tubes can continue to work, improving the overall reliability and stability of the system. The connection design helps to balance the heat load between the heat collecting tubes, avoid overheating of a single heat collecting tube, and extend the life of the equipment. Multiple vacuum heat collecting tubes 5 are connected to the heat exchanger 1 through pipelines, which simplifies the fluid circuit design of the system, reduces the connection points, and reduces the risk of leakage and maintenance difficulty.

[0068] Second embodiment:

[0069] A solar energy-based heat collection and heating method according to an embodiment of the present application comprises the following steps:

[0070] The heat collection efficiency is increased by providing multiple heat collection components, and the heat collection efficiency of the vacuum heat collection tube 5 is adjusted by adjusting the focusing plate 11 through the electric rotating shaft 10;

[0071] The temperature of the external environment is detected in real time by the temperature detector, and the external environment temperature signal is transmitted to the control module. The control module controls the valve switch between the components according to the external environment temperature, thereby controlling the working quantity of the heat collection component.

[0072] Specifically, the control module controls the valve switch according to the temperature signal, adjusts the working quantity of the heat collection component, realizes intelligent management, and optimizes energy use. Adjusting the working quantity of the heat collection component according to the change of the external temperature can avoid unnecessary energy waste and achieve energy conservation and emission reduction. When the temperature is low, the work of the heat collection component is reduced to save energy; when the temperature is high, the working component is increased to ensure the heating effect. By controlling the opening and closing of the valve, the working status of the heat collection component can be effectively managed to reduce equipment damage caused by overload or improper operation.

[0073] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
