Description

Technical Field

[0001] This utility model relates to the field of solar energy technology, and in particular to a solar collector tube fixing device. Background Technology

[0002] In solar water heating systems or concentrated solar power (CSP) equipment, solar collector tubes serve as the primary heat collection elements, and their stable and reliable installation is fundamental to ensuring the normal operation of the system. To guarantee heat collection efficiency and safety, the collector tubes must be securely installed on the support frame at a predetermined angle and position, while also possessing a certain degree of resistance to wind pressure and thermal expansion and contraction. Therefore, developing a solar collector tube fixing device that is easy to install, has a firm connection, and a reasonable structure has significant engineering application value and market demand.

[0003] In existing technologies, the fixing devices for solar collector tubes mainly achieve mechanical connections through bolts, clamping structures, or prefabricated limiting components. The upper shell and support are often fixed with screws or riveting, and the positioning device relies primarily on rigid pressure blocks or strips to press the collector tubes into place. Furthermore, to enhance overall stability, the fixing device is often designed as an integrated structure to improve its load-bearing capacity and wind resistance. While these traditional structures offer some practicality in terms of functionality, their assembly and transportation still present considerable inconvenience.

[0004] However, in existing technologies, the installation of solar collector tubes involves cumbersome procedures. Connecting components are mostly separate screw connections or fixing blocks, requiring numerous steps and tools. This results in low efficiency and complex operation during the fixing process, particularly hindering rapid installation under outdoor conditions, impacting the overall construction progress, and increasing labor costs and safety risks. Therefore, there is an urgent need for a structurally optimized and easily assembled solar collector tube fixing device to improve construction efficiency and the reliability of the fixing effect.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 The present invention provides an embodiment of a solar collector tube fixing device, comprising a bracket 1, which provides an overall support structure to form a stable base. A bracket 2 is provided on one side of the bracket 1, which serves as an auxiliary support component and is used to cooperate with the bracket 1 to form an installation frame structure. The collector tube body 4 is slidably connected inside the bracket 2. The slidable connection allows for convenient insertion and removal of the collector tube body 4, improving assembly efficiency. An installation component is provided on the top of the bracket 2. The installation component is used to directional limit and stably press the collector tube body 4 to ensure installation reliability.

[0034] The mounting assembly includes a lower housing 3, which serves as the structural foundation and provides internal space to accommodate positioning components. The bottom of the lower housing 3 is fixedly connected to the top of the bracket 2, ensuring a stable connection between the mounting assembly and the bracket 2. A lower positioning plate 5 is fixedly connected inside the lower housing 3, providing bottom limiting support for the heat collector tube body 4 to prevent axial displacement. Connecting buckles 6 are fixedly connected to both sides of the lower housing 3, engaging with hooks 8 on the upper housing 7 to form a detachable locking structure for easy assembly and maintenance. An upper housing 7 is located on top of the lower housing 3, forming a closed structure with the lower housing 3 to effectively protect the internal fastening mechanism. Hooks 8 are fixedly connected to both sides of the upper housing 7, quickly engaging with the connecting buckles 6 to simplify assembly. The hooks 8 and connecting buckles 6 engage to form a stable locking relationship, ensuring the upper housing 7 is not easily loosened during use. 7. An internal rotatable disc bolt 10 is connected. The disc bolt 10 acts as an adjustment component to control the downward pressure of the upper positioning plate 9, thereby pressing the heat collector tube body 4 to achieve positioning and fixation. One end of the disc bolt 10 is rotatably connected to the upper positioning plate 9. The upper positioning plate 9 is driven by the rotation of the disc bolt 10 to cooperate with the lower positioning plate 5 to clamp the heat collector tube body 4, forming a bidirectional limiting structure. One end of the disc bolt 10 is provided with a limiting component to prevent the disc bolt 10 from rotating excessively and to ensure safe and reliable positioning. The limiting component includes a limiting plate 11. The limiting plate 11 prevents over-adjustment from causing positioning failure or component damage through structural limiting. One end of the limiting plate 11 is fixedly connected to one end of the disc bolt 10 to achieve synchronous linkage with the disc bolt 10. The limiting plate 11 is rotatably connected inside the upper positioning plate 9. Through the rotational cooperation between the limiting plate 11 and the upper positioning plate 9, the consistency of action and structural integrity during the positioning process are ensured.

[0035] Reference Figure 4 and Figure 5The second bracket 2 has a slot 13 inside, which is used to achieve the limiting fit of the connecting structure. It achieves quick positioning and stable connection through the interlocking method. A connecting pin 12 is fixedly connected to one side of the first bracket 1. The connecting pin 12 acts as a connector to realize the mechanical connection between the first bracket 1 and the second bracket 2. The connecting pin 12 is slidably connected inside the second bracket 2. The sliding connection method facilitates the insertion action in the structural assembly process and improves the assembly and disassembly efficiency. A locking block 14 is rotatably connected inside the connecting pin 12. The locking block 14 achieves the interlocking and positioning with the slot 13 by rotation, which enhances the stability of the connecting structure. The interlocking of the locking block 14 and the slot 13 forms a reliable mechanical lock to prevent the brackets from loosening or disengaging due to force. A connecting rod 15 is rotatably connected to one end of the locking block 14. The connecting rod 15 acts as a transmission component to link the movement of the locking block 14 with the subsequent limiting structure. A limiting plate 16 is rotatably connected to one end of the connecting rod 15. The limiting plate 16 cooperates with the connecting rod 15 to connect the connecting pin. The connecting pin 12 internally implements limit control to prevent the locking block 14 from rotating out of control. The second limiting plate 16 is slidably connected inside the connecting pin 12. The sliding cooperation ensures that the limiting action is flexible and stable, which helps the locking block 14 to switch smoothly between engagement and release. The connecting pin 12 is equipped with a telescopic rod 17, which is used to drive the second limiting plate 16 to produce reciprocating motion, forming a reset control mechanism for the locking block 14. The outer wall of the telescopic rod 17 is fitted with a spring 18. The spring 18 provides an automatic reset force for the telescopic rod 17 through elastic action, realizing the active ejection or retraction of the limiting structure. One end of the telescopic rod 17 and the spring 18 are both fixedly connected to the other side of the second limiting plate 16, ensuring that the second limiting plate 16 can move together with the telescopic rod 17 under the elastic force of the spring 18. The other end of the telescopic rod 17 and the spring 18 are both fixedly connected inside the connecting pin 12, forming a closed and stable internal elastic reset mechanism in the connecting pin 12, ensuring the reliability and reusability of the structure during use.

[0036] Working principle: When using this solar collector tube fixing device, when first assembling bracket 2 and bracket 1, the connecting pin 12 on one side of bracket 1 is inserted into bracket 2. Then, the locking block 14 in the connecting pin 12 engages with the slot 13 to lock it. The locking block 14 is connected to the limiting plate 2 16 through the connecting rod 15 and is limited in the connecting pin 12. It is supported by the tension of the spring 18, so that the locking block 14 can be stably engaged in the slot 13, which achieves the effect of facilitating the assembly of the bracket.

[0037] When it is necessary to fix the heat collector tube body 4, one end of the heat collector tube body 4 is inserted into the bracket 2, and then the other end is placed on the lower positioning plate 5. Then, the two sides of the upper shell 7 are fastened by the hooks 8 into the connecting buckles 6. Then, the disc bolt 10 is rotated to drive the upper positioning plate 9 to press down through the limiting plate 11, so that the upper positioning plate 9 and the lower positioning plate 5 are fastened together to fix the heat collector tube body 4, thus achieving the effect of facilitating the fixing of the heat collector tube.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
