[0002] Solar energy is widely used due to its unique advantages such as "infinite" reserves, universal existence, and clean development and utilization. At present, solar trough collectors occupy a dominant position in solar energy utilization systems. Trough collectors are a type of heat collection device that uses light-to-heat conversion to achieve the conversion of light energy into heat energy through processes such as focusing, reflection, and absorption, so that the heat exchange medium reaches a certain temperature to meet different load requirements. Trough collectors belong to the category of medium- and high-temperature collectors, which can achieve relatively high temperatures for the heat exchange medium. They are applied to life and production fields such as thermal power generation, seawater desalination, heating projects, and absorption refrigeration.

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] It should be noted that when an element is referred to as being “fixed on” or “disposed on” another element, it may be directly on the other element or indirectly on the other element. When an element is referred to as being “connected to” another element, it may be directly connected to the other element or indirectly connected to the other element.

[0021] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0023] refer to Figure 1-4 The support structure for a trough-type solar thermal collector tube provided by an embodiment of the present invention is now described. The support structure for a trough-type solar thermal collector tube comprises a support frame 1, an upper end of which is provided with an adjustment mechanism 2 and a first fixing plate 5. The support frame 1 is connected to the first fixing plate 5 via the adjustment mechanism 2. A second fixing plate 6 is provided at the upper end of the first fixing plate 5. Bolts 8 are provided extending through the interior of the first and second fixing plates 5, and nuts 9 are threadedly connected to the circumferential surfaces of the bolts 8.

[0024] Specifically, the heat collecting tube is first installed between the first fixing plate 5 and the second fixing plate 6, and then the distance between the first fixing plate 5 and the support frame 1 is adjusted by the adjustment mechanism 2, thereby adjusting the distance between the heat collecting tube and the reflective plate, so as to focus the heat collecting tube and improve the heat collection effect of the heat collecting tube.

[0025] Adjustment mechanism 2 includes a movable frame 201, a threaded rod 202, and a handle 203. The movable frame 201 is disposed at the upper end of the support frame 1. The threaded rod 202 is internally threadedly connected to the movable frame 201. The upper end of the threaded rod 202 is rotatably connected to the first fixed plate 5, and the lower end of the threaded rod 202 is fixedly connected to the handle 203. During operation, rotating the handle 203, in conjunction with the threaded rod 202, drives the first fixed plate 5 to move, thereby adjusting the distance between the first fixed plate 5 and the support frame 1, which facilitates focusing of the heat collecting tubes.

[0026] The upper end of the mobile frame 201 is fixedly connected to a telescopic rod 4, and the end of the telescopic rod 4 away from the mobile frame 201 is fixedly connected to the first fixed plate 5. By providing the telescopic rod 4, the movement of the first fixed plate 5 can be limited by the action of the telescopic rod 4, so that the first fixed plate 5 can only move in the vertical direction.

[0027] The upper end surface of the support frame 1 is provided with a square hole 13 and a sliding hole 10. The lower end of the threaded rod 202 extends through the square hole 13. A slider 11 is slidably connected to the interior of the sliding hole 10. The upper end of the slider 11 is fixedly connected to the movable frame 201. A spring 12 is fixedly connected to the interior of the sliding hole 10. The end of the spring 12, which is away from the inner wall of the sliding hole 10, is fixedly connected to the slider 11. The provision of the square hole 13 facilitates the horizontal movement of the threaded rod 202. At the same time, the cooperation between the sliding hole 10 and the slider 11 can prevent the heat collecting tube from rupturing due to expansion and contraction. The action of the spring 12 also facilitates the reset of the heat collecting tube.

[0028] A reinforcing rod 3 is fixedly connected to the interior of the support frame 1, and the reinforcing rod 3 is in an X-shaped shape. By providing the reinforcing rod 3, the stability of the support frame 1 can be enhanced.

[0029] Mounting slots 14 are defined on the inner arc surfaces of both the first and second fixing plates 5, 6. Protective pads 7, made of high-temperature-resistant rubber, are securely attached to these slots. These pads prevent damage to the heat collecting tubes caused by the combined use of the first and second fixing plates 5, 6, thereby extending their service life.

[0030] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
