[0029] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0030] Referring to Figures 1 to 3 , an embodiment provided by the present utility model: A fixture for a solar collector includes a support plate 1. A plurality of claws 2 are fixedly connected to the top end of the support plate 1. These claws 2 are not only numerous but also reasonably distributed, ensuring a wide and uniform contact surface with the inner and outer pipes during installation. Two fixing components for providing support are fixedly connected to the bottom end of the support plate 1. The fixing components include two fixed columns 3. The top end of the fixed column 3 is fixedly connected to the bottom end of the support plate 1. A collar 4 is fixedly connected to the bottom end of the fixing component. Here, the fixed column 3 is used to connect the support plate 1 and the collar 4. A rubber pad 5 is slidably connected to the inner wall of the collar 4. A limit ring 6 is fixedly connected to the top end of the rubber pad 5. Here, the limit ring 6 is used to limit the sliding range of the rubber pad 5. The outside of the limit ring 6 is slidably connected to the inner wall of the collar 4. A plurality of springs 7 are fixedly connected to the top end of the limit ring 6. One end of the spring 7 is fixedly connected to one side of the inner wall of the collar 4. Here, the spring 7 can provide a force when this fixture is connected to the solar collector, making the connection between the solar collector and the fixture closer and improving the sealing performance of the solar collector.
[0031] Referring to Figure 1 and Figure 4, a strength layer 8 is fixedly connected to the inner wall of the support plate 1. Both ends of the strength layer 8 are fixedly connected to the inner wall of the support plate 1. The material of the strength layer 8 is graphene-reinforced composite material, which has extremely high strength and rigidity and can withstand various forces from the external environment, such as wind pressure, snow load, etc. An energy storage layer 9 is fixedly connected to the inner wall of the strength layer 8. Both ends of the energy storage layer 9 are fixedly connected to the inner wall of the support plate 1. The material of the energy storage layer 9 is phase change energy storage material. The phase change energy storage material can undergo a phase change at a specific phase change temperature, absorbing or releasing a large amount of latent heat. This characteristic enables the energy storage layer 9 to absorb excess heat during the operation of the collector and release it when needed, thereby maintaining the temperature stability of the fixture and reducing heat loss. An insulation layer 10 is fixedly connected to the inner wall of the energy storage layer 9. Both ends of the insulation layer 10 are fixedly connected to the inner wall of the support plate 1. The material of the insulation layer 10 is aerogel insulation material. Aerogel is a lightweight and porous material with extremely low thermal conductivity and good heat insulation performance. By setting the insulation layer 10 inside the fixture, heat can be effectively prevented from being transferred to the external environment through the fixture, thereby reducing heat loss and improving the thermal efficiency of the collector.
[0032] A toughness layer 11 is fixedly connected to the inner wall of the insulation layer 10. Both ends of the toughness layer 11 are fixedly connected to the inner wall of the support plate 1. The material of the toughness layer 11 is shape memory alloy. Shape memory alloy is a smart material with unique shape memory effect and superelasticity. When the fixture is subjected to external force, the toughness layer 11 can deform to absorb energy; when the external force disappears, it can return to its original shape. This characteristic enables the fixture to have good shock absorption performance and can protect the collector from damage caused by external impacts. A durability layer 12 is fixedly connected to the inner wall of the toughness layer 11. Both ends of the durability layer 12 are fixedly connected to the inner wall of the support plate 1. The material of the durability layer 12 is carbon nanotube-reinforced composite material. Carbon nanotubes have excellent mechanical properties, wear resistance and corrosion resistance, and can significantly improve the strength and durability of the material. By setting the durability layer 12 inside the fixture, the wear resistance and corrosion resistance of the fixture can be further enhanced, its service life can be extended and the maintenance cost can be reduced.
[0033] Working principle: The fixture is cleverly arranged between the inner and outer tubes, keeping the free ends of the inner and outer tubes in a coaxial and concentric support state. During the installation process, multiple clamping claws 2 fixedly connected to the top of the support plate 1 are in close contact with the inner and outer tubes, ensuring the stability and sealing performance of the fixture. These clamping claws 2 are not only numerous but also reasonably distributed, and can widely and evenly cover the contact surfaces of the inner and outer tubes.
[0034] At the bottom end of the support plate 1, two fixing components are fixedly connected. These two components are connected by a fixing column 3 and a collar 4, providing stable support for the entire fixture. Among them, the fixing column 3 is responsible for connecting the support plate 1 and the collar 4 to ensure the integrity of the structure; while the collar 4 forms a flexible adjustment mechanism by slidingly connecting a rubber pad 5 and a limit ring 6. When the fixture is connected to the collector, the rubber pad 5 is subjected to pressure and squeezes the limit ring 6, causing the limit ring 6 to slide along the inner wall of the collar 4. At the same time, a plurality of springs 7 fixed to the top end of the limit ring 6 are compressed, generating an elastic force acting between the fixture and the collector, making the connection between the two closer and improving the sealing performance of the collector.
[0035] Inside the fixture, an intensity layer 8, an energy storage layer 9, a heat insulation layer 10, a toughness layer 11, and a durability layer 12 are arranged in sequence, each playing an important role. The intensity layer 8 is made of a graphene-reinforced composite material, having extremely high strength and rigidity, and being able to withstand various forces in the external environment; the energy storage layer 9 uses a phase change energy storage material, which can absorb or release heat when the temperature changes, maintaining the temperature stability of the fixture and reducing heat loss; the heat insulation layer 10 is made of an aerogel heat insulation material, effectively preventing heat from being transferred to the external environment and reducing heat loss; the toughness layer 11 uses a shape memory alloy, having good shock absorption performance, protecting the collector from external impact damage; the durability layer 12 uses a carbon nanotube-reinforced composite material, improving the wear resistance and corrosion resistance of the fixture, extending the service life and reducing the maintenance cost.
[0036] In summary, the fixture for the solar collector realizes the effective support and protection of the collector through its unique structural and material combination. During the working process, each component works together to ensure the stability, sealing performance, and durability of the fixture. Especially in the application between the inner and outer tubes at the tail of the all-glass medium and high-temperature solar collector, this fixture, with its unique design and structural principle, realizes the coaxial and concentric support of the free ends of the inner and outer tubes, effectively fixing the load bearing of the inner tube, and playing a role in releasing the pressure caused by the thermal expansion and contraction of the inner heat collection tube. At the same time, this fixture minimizes the heat load conduction loss by the way of point contact with the inner and outer tube walls, demonstrating its excellent performance and value.
[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
