Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically a photovoltaic tracking bracket. Background Technology

[0002] With the development of the photovoltaic industry, photovoltaic tracking brackets have been widely used, but there are still some problems in their application.

[0003] For example, in the Chinese utility model patent with publication number CN221042747U, entitled "Swing Arm of Photovoltaic Tracking Frame and Photovoltaic Tracking Frame," the swing arm and main shaft are assembled. Because the contact area between the bolts connecting the swing arm and the main shaft is small, the swing arm provides torsional force during rotation. Therefore, the swing arm is prone to damaging the main shaft during rotation, leading to deformation. Thus, it is necessary to provide a photovoltaic tracking bracket to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a photovoltaic tracking bracket, which provides a main shaft protection component and a clamp to increase the contact area between the main shaft and the swing arm, thus protecting the main shaft from damage.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a photovoltaic tracking bracket, comprising: a column; a main shaft, the main shaft being pivotally connected to the top of the column; a main shaft protective component snapped onto the main shaft; a clamp covering the main shaft protective component; and a swing arm disposed on one side of the main shaft, the swing arm comprising a head and a tail, the head being located near the clamp and the tail being located away from the clamp, the head being fixedly connected to the clamp and the tail being connected to one end of an electric push rod via a pin, the other end of the electric push rod being hinged to the column.

[0006] Furthermore, the spindle protection component is U-shaped, and both of its two parallel side edges are provided with folded edges. The two folded edges on each side are folded outwards, and the distance between the two folded edges is the same as the width of the clamp. The swing arm has an inwardly curved portion along its length; an arc-shaped transition portion along its height; and a gradually thinning portion near the tail end along its width. The swing arm is manufactured by stamping. A swing arm protection plate is provided on the side of the head facing the clamp, and a swing arm pad is provided on the other side. The swing arm pad, head, and swing arm protection plate are fixedly connected to the clamp by four bolts. A pin protection component is provided between the tail end and the electric push rod.

[0007] The beneficial effects of this utility model are as follows: This utility model provides a photovoltaic tracking bracket. The swing arm in this bracket is manufactured using a stamping process, with no welded parts, resulting in a simple structure, light weight, and reduced overall cost. The installation of a main shaft protection component and a clamp increases the contact area between the main shaft and the swing arm, protecting the main shaft and preventing damage. The installation of a swing arm gasket, swing arm baffle, and pin protection component enhances the strength and rigidity of the swing arm. Attached Figure Description

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments.

[0018] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0019] like Figure 1 and Figure 2 As shown, a photovoltaic tracking bracket includes: a column 10; a main shaft 3, the main shaft 3 being pivotally connected to the top of the column 10; a main shaft protection member 1 snapped onto the main shaft 3; a clamp 2 wrapped around the main shaft protection member 1; and a swing arm 4 disposed on one side of the main shaft 3, the swing arm 4 including a head and a tail, the head being located on the side closer to the clamp 2, the tail being located on the side farther from the clamp 2, the head being fixedly connected to the clamp 2, and the tail being connected to one end of an electric push rod 9 via a pin 8, the other end of the electric push rod 9 being hinged to the column 10.

[0020] In this embodiment, by setting a main shaft protection component 1 and a clamp 2 on the main shaft 3, when the photovoltaic module is subjected to external force (changes in the external environment such as wind and rain) and needs to undergo slight changes, the electric push rod 9 extends and retracts accordingly, driving the swing arm 4 to rotate, and in turn driving the main shaft protection component 1, the clamp 2 and the main shaft 3 to rotate, so as to ensure the dynamic balance of the photovoltaic module. The main shaft protection component 1 and the clamp 2 increase the contact area between the main shaft 3 and the swing arm 4, effectively solving the problem of deformation of the main shaft 3 under force.

[0021] As an optional implementation method, such as Figure 2 As shown, the spindle protection component 1 is U-shaped. The two parallel side edges of the spindle protection component 1 are provided with folded edges 1-1. The two folded edges 1-1 on each side are folded outward. The distance between the two folded edges 1-1 is the same as the width of the clamp 2, which is used to make the clamp 2 more firmly fixed along the direction of the spindle 3.

[0022] Optional, such as Figure 4 and Figure 5As shown, the swing arm 4 has an inwardly curved portion 4-1 along its length direction to accommodate different installation widths; the swing arm 4 has an arc transition portion 4-2 along its height direction, which, according to topology optimization results, helps to reduce material usage; the swing arm 4 has a gradually thinning portion 4-3 near its tail along its width direction, which can better facilitate the transmission of force of the swing arm 4 and reduce material usage.

[0023] Optionally, the swing arm 4 is manufactured by stamping, which has a short processing cycle and is simple to assemble on site.

[0024] As an optional implementation method, such as Figure 1 and Figure 2 As shown, the head is provided with a swing arm protection plate 6 on the side facing the clamp 2, and a swing arm pad 7 on the other side. The swing arm pad 7, the head, the swing arm protection plate 6 and the clamp 2 are fixedly connected by four bolts. The main shaft protection component 1 is tightly attached to the main shaft 3 under the action of the four bolts. There is no tolerance between the four bolts and the corresponding bolt holes, which ensures a good fit. When the swing arm 4 is running, the main shaft protection component 1 is further tightened under the action of rotational force, which better protects the main shaft 3.

[0025] As an optional implementation method, such as Figure 1 and Figure 2 As shown, a pin protection component 5 is provided between the tail and the electric push rod 9. The pin protection component 5 increases the connection node between the pin 8 and the swing arm 4, so that the swing arm 4 is protected from damage by the pin 8 with a lower wall thickness.

[0026] The assembly sequence of the photovoltaic tracking bracket is as follows:

[0027] S1. Pivot the main shaft 3 to the top of the column 10, and fix one end of the electric push rod 9 on the column.

[0028] S2. The tail of the swing arm 4 is pre-installed with the pin protection piece 5 by bolts.

[0029] S3. Secure the spindle protector 1 to the appropriate position on the spindle 3, and then place the clamp 2 outside the spindle protector 1. Since the spindle protector 1 and the clamp 2 are three-sided enclosed structures, they can be easily placed on the spindle 3 and are not easy to slip off. No other auxiliary devices or manual intervention are required to ensure their stability.

[0030] S4. Place the swing arm pad 7 and the swing arm protection plate 6 on both sides of the head, and then connect the head to the clamp 2 with four bolts and lock them together, so that the swing arm protection plate 6 presses tightly against the main shaft protection component 1.

[0031] S5. Connect the tail of the swing arm 4 to the other end of the electric push rod 9 via the pin 8.

[0032] Through the above technical solution, the photovoltaic tracking bracket of this utility model achieves the manufacturing of the swing arm 4 using a stamping forming process, which eliminates welded parts, resulting in a simple structure, light weight, reduced manufacturing cycle, convenient on-site adjustment, and easy installation. The strength and rigidity of the swing arm 4 are increased by setting the swing arm pad 7, swing arm protection plate 6, and pin shaft protection component 5. The contact area between the main shaft 3 and the swing arm 4 is increased by setting the main shaft protection component 1 and clamp 2, preventing damage to the main shaft 3 and improving the contact strength and rigidity of the main shaft 3.

[0033] In some possible embodiments, the swing arm 4 can be formed by stamping, or it can be replaced by welded or bent parts; the protection of the main shaft 3 can be a clamp 2 or other wrapping form.

[0034] Those skilled in the art should understand that the discussion of any of the above embodiments is merely exemplary and is not intended to imply that the scope of the present invention (including the claims) is limited to these examples; within the framework of the present invention, the technical features of the above embodiments or different embodiments can also be combined, the steps can be implemented in any order, and there are many other variations of the different aspects of the present invention as described above, which are not provided in the details for the sake of brevity.

[0035] This utility model is intended to cover all such substitutions, modifications, and variations that fall within the broad scope of the appended claims. Therefore, any omissions, modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
