Description

Technical Field

[0001] This utility model relates to the field of solar concentrating and collecting technology, and in particular to a rotary support suitable for a trough solar dual-axis tracking system, specifically a rotary support structure for a dual-axis tracking collector. Background Technology

[0002] In the field of solar energy utilization, dual-axis tracking solar collectors are a common type of facility. Because they can accurately capture solar radiation along its entire trajectory, they can significantly improve energy capture efficiency. Compared with traditional fixed structures, solar energy utilization can be increased by 30%-40%, so they have gradually become the main application method.

[0003] As the physical basis of the dual-axis tracking solar collector, the performance of its rotating support structure has a significant impact on the overall equipment. In particular, the driving load and operational stability when the solar collector frame rotates directly determine the efficiency, energy consumption, and reliability of the entire tracking system.

[0004] Currently, the support structures of existing parabolic trough solar dual-axis tracking collectors mostly employ complex mechanical transmission devices, resulting in problems such as bulky structures, difficult installation and maintenance, and high costs. In traditional designs, the rotating support structure lacks stability and has a large driving load, leading to high energy consumption and insufficient stability. Utility Model Content

[0005] This invention addresses the shortcomings of existing technologies by providing a rotating support structure for a dual-axis tracking solar collector, which reduces the driving load and improves system stability.

[0006] This utility model is achieved through the following technical solution: a rotary support structure for a dual-axis tracking solar collector is provided, including a telescopic rod, a base, a support beam fixedly connected to the base, and a support seat fixedly connected to the crossbeam of the solar collector frame. The fixed part of the telescopic rod is hinged to the support beam through a first horizontal axis, and the extended end of the telescopic rod is hinged to a connecting seat through a second horizontal axis. The connecting seat is fixedly connected to the crossbeam. The support seat is rotatably connected to the base through a rotating shaft.

[0007] It also includes a balance spring with one end connected to the crossbeam, and the other end of the balance spring connected to the support beam. The connection point between the balance spring and the crossbeam is located between the connecting seat and the support seat, and the connection point between the balance spring and the support beam is located between the base and the first horizontal axis.

[0008] This solution achieves support for the crossbeam by setting up a support base, as well as relative rotation between the crossbeam and the base. The crossbeam is driven to rotate around the rotation axis by a telescopic rod. At the same time, the elastic force of the balance spring is used to counteract the torque generated by the weight of the collector, thereby reducing the driving energy consumption.

[0009] As an optimization, the support base includes two connecting plates I fixedly connected to the crossbeam and arranged opposite each other along the width direction of the crossbeam. Connecting plates II are fixedly connected to the opposite sides of the two connecting plates I, and the rotating shaft passes through the two connecting plates II. Both ends of the rotating shaft are rotatably connected to the base via bearings with mounting brackets. This optimized solution increases the structural strength at the crossbeam support point by setting connecting plates I; achieves a rotatable connection between the crossbeam and the base by setting connecting plates II, ensuring the crossbeam rotates under the drive of the telescopic rod; and reduces the frictional resistance during crossbeam rotation by setting bearings with mounting brackets, thus lowering drive energy consumption.

[0010] As an optimization, a limiting sleeve is fitted onto the rotating shaft, located between the connecting plate II and the bearing with a seat. One end of the limiting sleeve abuts against the connecting plate II, and the other end abuts against the bearing with a seat. This optimized solution, by setting the limiting sleeve, achieves the axial positioning of the connecting plate II on the rotating shaft, thereby achieving the positioning of the crossbeam.

[0011] As an optimization, a connecting plate III is provided between the two connecting plates II, with both ends of the connecting plate III fixedly connected to the two connecting plates II respectively. This optimized solution uses the connecting plate III to fix the two connecting plates II into a whole, which improves the overall structural strength of the support and better ensures that the two connecting plates II are parallel to each other.

[0012] As an optimization, the two ends of the two connecting plates I are fixed together by arc-shaped fixing plates. The arc-shaped fixing plates are provided with arc-shaped grooves that fit the crossbeam, and the arc-shaped fixing plates are fixed to the crossbeam. This optimization scheme further improves the overall structural strength of the support base by setting arc-shaped fixing plates.

[0013] As an optimization, the base includes a rotating support plate, two vertical beams above the rotating support plate, and a reinforcing beam between the two vertical beams. Both ends of the reinforcing beam are fixedly connected to the two vertical beams. A seat plate supporting and connected to the seated bearing is fixedly connected to the top of each vertical beam, and a transition plate supporting and connected to the rotating support plate is fixedly connected to the bottom of each vertical beam. The optimized base is H-shaped overall. The vertical beams provide support for the seated bearing, the reinforcing beams improve the stability of the two vertical beams, and the seat plate and transition plate facilitate the fixing of the seated bearing to the vertical beams and the vertical beams to the rotating support plate.

[0014] As an optimization, two opposing buckle plates are fixed to the fixing part of the telescopic rod. Each buckle plate has an arc-shaped groove adapted to the fixing part of the telescopic rod. The two buckle plates are fixed together by bolts, and the first horizontal axis passes through the two buckle plates and the support beam. This optimized solution, through the buckle plates, facilitates the connection between the telescopic rod and the support beam, and also features a simple structure that is easy to assemble and disassemble.

[0015] The beneficial effects of this utility model are as follows: the base, support seat, and telescopic rod form a modular design, which facilitates assembly. By setting up the balance spring and telescopic rod, not only is the rotation of the crossbeam realized, but the driving load is also reduced and the stability of the system is improved.

[0020] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0021] like Figure 1 The rotating support structure for a dual-axis tracking solar collector shown includes a telescopic rod 2, a base 16, a support beam 17 fixedly connected to the base, and a support seat fixedly connected to the crossbeam 6 of the solar collector frame. The base is used to provide support and a rotation fulcrum for the crossbeam of the solar collector frame, and the telescopic rod is used to provide power for the rotation of the crossbeam.

[0022] In this embodiment, the telescopic rod 2 is an electric push rod. The fixed part of the telescopic rod is hinged to the support beam via a first horizontal shaft 1, and the extended end of the telescopic rod is hinged to a connecting seat 15 via a second horizontal shaft 3. The connecting seat is fixed to the crossbeam 6, and a pin hole is provided on the connecting seat for the second horizontal shaft to pass through. The support beam 17 extends horizontally out of the base, and the end of the support beam away from the base 16 is hinged to the fixed part of the telescopic rod via the first horizontal shaft. The first horizontal shaft is located below the second horizontal shaft, and the first horizontal shaft and the second horizontal shaft are parallel to each other and both extend horizontally.

[0023] To facilitate disassembly and assembly, two oppositely arranged buckle plates are fixed on the fixing part of the telescopic rod in this embodiment. Each buckle plate is provided with an arc-shaped groove that matches the fixing part of the telescopic rod. The two buckle plates are fixed together by bolts, and the first horizontal axis 1 passes through the two clamps and the support beam.

[0024] The support base is rotatably connected to the base 16 via a rotating shaft 7, which is parallel to the first and second horizontal axes. The support base includes two connecting plates I13 fixed to the crossbeam and arranged opposite to each other along the width direction of the crossbeam. Connecting plates II12 are fixed to the opposite sides of the two connecting plates I13. The rotating shaft 7 passes through the two connecting plates II12, and both ends of the rotating shaft 7 are rotatably connected to the base 16 via bearings 8.

[0025] A limiting sleeve 9 is fitted onto the rotating shaft, located between the connecting plate II 12 and the seated bearing 8. One end of the limiting sleeve 9 abuts against the connecting plate II 12, and the other end abuts against the seated bearing 8, thus limiting the axial movement of the connecting plate II 12. A bearing housing locating pin 10 is provided on the housing of the seated bearing, abutting against the rotating shaft, to axially position the rotating shaft. The rotating shaft 7 and the limiting sleeve 9 cooperate to achieve ±0.1° angle control, while the bearing housing locating pin 10 ensures axial stability, improving solar tracking accuracy and adapting to the needs of different scale solar collector field arrangements, especially suitable for complex terrain.

[0026] This embodiment also includes a balance spring 5 connected at one end to the crossbeam, and the other end of the balance spring 5 connected to the support beam 17. Connecting rings 4 are fixed to the bottom surface of the crossbeam and the top surface of the support beam, respectively, for hanging the balance spring. The connection point between the balance spring and the crossbeam is located between the connecting seat and the support seat, and the connection point between the balance spring and the support beam is located between the base and the first horizontal axis. The balance spring counteracts the torque generated by the collector's own weight, reducing drive energy consumption and adjusting tension in real time to balance the load. In practical applications, the balance spring can counteract more than 30% of the self-weight load, reducing drive power consumption by 10%-20%, making it suitable for low-power drive systems.

[0027] To improve structural strength, a connecting plate III 11 is provided between the two connecting plates II 12 in this embodiment. Both ends of the connecting plate III 11 are fixedly connected to the two connecting plates II 12. In this embodiment, both ends of the connecting plate III 11 are welded to the two connecting plates II 12. The connecting plate III secures the two connecting plates II 12 together, ensuring the overall structural strength of the support base. During welding, it also better ensures that the two connecting plates II 12 are parallel to each other.

[0028] The two ends of the two connecting plates I13 are fixed together by arc-shaped fixing plates 14. The arc-shaped fixing plates 14 are provided with arc-shaped grooves that are adapted to the crossbeam 6, and the arc-shaped fixing plates 14 are fixed to the crossbeam 6. In this embodiment, the crossbeam, connecting plate II12, and arc-shaped fixing plates 14 are welded into an integral structure, which enhances the torsional resistance of the structure.

[0029] The base 16 includes a rotating support plate 16.5, two vertical beams 16.1 located above the rotating support plate, and a reinforcing beam 16.3 located between the two vertical beams 16.1. Both ends of the reinforcing beam 16.3 are fixedly connected to the two vertical beams 16.1 respectively. In this embodiment, both ends of the reinforcing beam 16.3 are welded to the two vertical beams 16.1 respectively. A seat plate 16.2, supporting and fixedly connected to the seated bearing, is fixedly connected to the top of the vertical beam. A transition plate 16.4, supporting and fixedly connected to the rotating support plate, is fixedly connected to the bottom of the vertical beam. The vertical beams and reinforcing beam are made of square or round tubing and are welded to form a lightweight, rigid frame, facilitating installation and expansion.

[0030] In this embodiment, the rotating support structure comprises modules such as a base, support seat, telescopic rod, and balance spring, improving modularity and facilitating assembly. During use, the base is mounted and fixed on the rotating support. The rotation of the rotating support drives the base to rotate around its vertical axis. The rotating support is existing technology, using a reducer to provide rotational power; its structure will not be described in detail here. When angle adjustment is required, an electric push rod drives the crossbeam to rotate around the axis of rotation, achieving pitch angle adjustment. Simultaneously, the balance spring reduces load, solving the problems of bulkiness, high energy consumption, and poor stability in traditional dual-axis tracking systems. This provides an efficient and reliable support solution for the large-scale application of trough solar power systems.
