Technical Field

[0001] The utility model relates to the technical field of solar thermal collectors, in particular to a thermal collector used for roof heating. Background Art

[0002] Trough collectors are core products in thermal power generation. They can collect the sun's heat energy and then transfer it through the collector tube to generate mechanical energy to generate electricity. The application of trough collectors in the field of thermal power generation has become increasingly widespread, and their position as a core product is irreplaceable. The uniqueness of trough collectors lies in their trough structure, which can maximize the reception and concentration of solar radiation heat energy. As the sun moves across the sky, the trough collector adjusts its angle to always maintain the best alignment with the sunlight, ensuring maximum reception of solar energy. In this process, the trough collector can effectively collect the sun's heat energy and transfer it to the thermal energy conversion system through the collector tube.

[0003] The opening sizes of conventional trough collectors on the current market are mainly 2.55 meters, 3 meters, 3.2 meters, etc. Most of these products use a torque tube with a slewing reducer. However, these collectors are large in size, heavy in weight, and their bracket structures are relatively complex, making them unsuitable for rooftop placement. Utility Model Content

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

[0032] Example:

[0033] A collector for roof heating comprises a support frame 1 and a reflector lens 6, wherein at least two support frames 1 are provided, and a fixing seat 2 is provided on the top surface of each support frame 1, and a reflector support component 3 is provided between the two fixing seats 2. At least two reflector lenses 6 are provided and are installed in a row on the reflector support components 3, and heat collecting tube supports 4 are connected to each fixing seat 2, and heat collecting tubes 7 are provided between the heat collecting tube supports 4. An electric pushing component 5 for pushing the reflector support components 3 is also provided on the support frame 1.

[0034] It is explained that the electric push component 5 is an electric actuator. The electric push component 5 mainly moves back and forth within a certain range of travel, and can realize remote control and centralized control. The electric push component 5 used in this application can be customized according to its special travel design in this collector. The use of the electric push rod 54 as an actuator can not only significantly reduce the overall weight of the collector, improve the portability and flexibility of the equipment, but also effectively reduce the cost of the drive system. At the same time, the introduction of the electric push component 5 will further expand the installation application range of the collector, making it more adaptable to a variety of application scenarios.

[0035] Specifically, the fixed seat 2 is a bearing seat, and the reflector support component 3 is rotatably connected between the two bearing seats, wherein the bearing seat, as an important supporting component in the mechanical system, has excellent load-bearing capacity, can withstand high loads and vibrations from the equipment, and ensure the stable operation of bearings and rotating parts. Secondly, the bearing seat has excellent thermal stability and wear resistance. Under high-speed rotation and high-temperature environments, the bearing seat can maintain stable performance, and will not affect the accuracy and life of the bearing due to thermal expansion or wear, so that it can operate stably for a long time in harsh working environments.

[0036] Combined with the accompanying drawings Figure 1-Figure 4 The reflector support component 3 includes a first connecting plate 31, a second connecting plate 32 and a torque tube 33. One end of the first connecting plate 31 and the second connecting plate 32 are rotatably connected to the two bearing seats respectively, and the other ends of the first connecting plate 31 and the second connecting plate 32 are fixedly connected to the two end pipe openings of the torque tube 33 respectively. The outer wall of the torque tube 33 is also connected to multiple lens brackets 34.

[0037] It is explained that the entire reflector support component 3 is powered by the electric push component 5 connected to the bearing seat, thereby driving the reflector support component 3 to move. One end of the first connecting plate 31 and the second connecting plate 32 in the reflector support component 3 are respectively rotatably connected to the two bearing seats, and the torque tube 33 is fixed between the first connecting plate 31 and the second connecting plate 32. Among the above parts, the first connecting plate 31, the second connecting plate 32 and the torque tube 33 are all made of Q235B or 45 steel, wherein Q235B steel is a low-carbon structural steel with good toughness and welding performance, and is easy to process and cut. It has moderate strength and can withstand certain pressure and load, while 45 steel is a medium-carbon structural steel with high strength and hardness, and good wear resistance and fatigue strength. During manufacturing, operators can choose according to actual needs.

[0038] It is worth noting that the lens brackets 34 are fixed in rows on the outer wall of the torque tube 33, wherein every two lens brackets 34 form a group, and at least two groups are provided. The lens brackets 34 include a supporting frame 341, and the supporting frame 341 is fixed on the outer wall of the torque tube 33 through a through hole opened in the middle. Trays 342 are also provided at both ends of the supporting frame 341, and the trays 342 are screwed on the outer wall of the supporting frame 341.

[0039] It is explained that the carrier 341 is firmly connected to the torque tube 33 through the through hole opened in the middle. This fixing method can significantly improve the load capacity of the carrier 341, ensuring that it can stably withstand various forces during use. By arranging a tray 342 on the carrier 341, it can effectively avoid direct contact between the reflective lens 6 and the carrier 341, thereby reducing the risk of damage caused by friction or collision. This design ensures the safety of the reflective lens 6 during transportation and storage, while also extending its service life, and can also simplify the installation and removal process of the reflective lens 6 and improve work efficiency.

[0040] Combined with the accompanying drawings Figure 1-Figure 6 One end of the electric pushing component 5 is connected to the bottom of the support frame 1, and the other end of the electric pushing component 5 is rotatably connected to the second connecting plate 32. The electric pushing component 5 includes a fixed plate 51, a motor 52, an outer tube 53 and a push rod 54. The fixed plate 51 is installed on the inner bottom surface of the support frame 1, and the bottom of the outer tube 53 is hinged to the fixed plate 51. The push rod 54 is slidably arranged inside the outer tube 53. A connecting ring is also arranged on the top of the push rod 54, and the connecting ring is rotatably connected to the second connecting plate 32.

[0041] It is further worth noting that the support frame 1 is a hollow iron pipe frame, and the support frame 1 is in a trapezoidal shape, and the opening of the reflector lens 6 is 1.3 meters, wherein the support frame 1 adopts a hollow iron pipe structure, and the overall opening size of the reflector lens 6 is also moderately reduced. This improvement measure not only effectively reduces the overall weight of the collector product, but also improves the stability and durability of the product. Through this optimization, the collector is lighter and easier to install and transport while maintaining high efficiency.

[0042] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
