Description

Technical Field

[0001] The invention relates to the technical field of solar photovoltaics, and in particular to an independent column photovoltaic support with excellent earthquake resistance. Background Art

[0002] Independent column photovoltaic support is a common support structure in solar power generation projects. It is supported by an independent column and fixed at a suitable angle according to the sunshine conditions in different regions to maximize the absorption of solar radiation. The advantages of this support system are quick construction, easy maintenance, safety and reliability, high durability, and it is suitable for framed and frameless components. The simple structure and easy installation of the independent column photovoltaic support system make it a cost-effective solution for smaller photovoltaic power station systems.

[0003] At present, most independent column photovoltaic brackets have deficiencies in earthquake resistance due to their own structural limitations. Independent column photovoltaic brackets mainly rely on a single row of columns for support, and this structure is easily affected when facing strong earthquakes. The connectors and nodes in the bracket are often the weak links of the structure. When there is a lack of multi-directional support and insufficient ability to disperse seismic forces, it is easy to be damaged and destroyed during an earthquake, resulting in a decrease in the overall stability of the bracket.

[0004] To this end, we provide an independent column photovoltaic bracket with excellent seismic performance, which improves the seismic performance of the independent column photovoltaic bracket, improves its stability during use, and is easy to install. It has practical significance and good application prospects. Summary of the invention

The high-strength spring 23 is fixed on the upper and lower parts of the axial ring 25, and the outer side of the high-strength spring 23 is wrapped with a rubber protective sleeve 24.

[0034] The central ball joint seat 3 includes a base 31, a spring 32, an elastic rubber ring 33, a middle seat 34, a sliding lining 35, a top cover 36, a ball joint 37, a support joint 38, and a screw 39. The base 31 is connected to the shaft column 22 at the bottom, and is connected to the spring 32 and the elastic rubber ring 33 at the top. The spring 32 and the elastic rubber ring 33 are connected to the middle seat 33 and are wrapped with a rubber protective cover on the outside. The middle seat 33 is connected to the top cover 36 by screws 39, and has a sliding lining 35 inside to wrap the ball joint 37, and the ball joint 37 is connected to the support joint 38.

[0035] The photovoltaic support panel 4 includes a support plate 41, a short screw 42, a long screw 43, a ball joint top 44, a small ball joint 45, a ball joint bottom 46, a small screw 47, and a hanging ear 48. The support plate 41 is connected to the support joint 38 by the short screw 42 and the long screw 43. Slots are left at the top corners of the support plate 41. The ball joint top 44, the small ball joint 45 and the ball joint bottom 46 are connected to the support plate 41 by small screws 47, and a hanging ear 48 is installed next to the slot.

[0036] The shock-absorbing damping rod 5 includes a concave rod 51, a convex rod 52, a rubber protective sleeve 53, an outer spring 54, and an inner spring 55. The inner spring 55 connects the concave rod 51 and the convex rod 52. The outer spring 54 is installed outside the concave rod 51 and the convex rod 52. The outer spring 54 is wrapped with a rubber protective sleeve 53.

[0037] One end of the steel cable 6 is connected to the anchor ring 13 on the foundation 1 , and the other end is connected to the hanging ears 48 around the top corners of the photovoltaic support panel 4 .

[0038] The following is a detailed description of the working principle of this independent column photovoltaic bracket with excellent seismic performance.

[0039] like Figure 1-10 As shown, during use, when vibration occurs, the concrete protective layer 11 first receives the vibration from the foundation, and then the vibration is transmitted to the rubber protective layer 12, and then transmitted to the load-bearing column 2 by the rubber protective layer 12. In this process, the concrete protective layer 11 and the rubber protective layer 12 absorb the vibration to achieve the first level of shock absorption.

[0040] The vibration of the foundation is transmitted to the load-bearing column 2. Under the combination of the two high-strength springs 23, the axial collar 25 shakes irregularly to release force and reduce shock, so that the vibration transmitted to the central ball joint seat 3 and the shock-absorbing damping rod 5 is weakened, realizing the second level of shock absorption. The rubber protective sleeve 24 protects the high-strength spring 23 and enables it to work normally.

[0041] The vibration of the load-bearing column 2 is transmitted to the central ball joint seat 3. The spring 32, elastic rubber ring 33 and sliding lining 35 inside the central ball joint seat 3 will further absorb the vibration, reduce the vibration transmitted to the photovoltaic support panel 4, and realize the third level of shock absorption.

[0042] The vibration of the load-bearing column 2 is transmitted to the shock-absorbing damping rod 5, and the shock-absorbing damping rod 5 is extended and retracted through the action of the inner spring 55 and the outer spring 54, thereby further absorbing the vibration and improving the shock-absorbing effect.

[0043] The photovoltaic support plate 4 adopts a "M-shaped" design to reduce its own weight and save materials. The photovoltaic support plate 4 is connected to the central ball joint seat 3 through the ball joint 37, and is connected to the shock-absorbing damping rod 5 through the small ball joint 45, so that the connection part can produce a small rotation, effectively preventing the connection part from being damaged by force, and the friction between the ball joint 37 and the small ball joint 45 can also reduce vibration.

[0044] One end of the steel cable 6 is connected to the anchor ring 13 on the foundation 1, and the other end is connected to the hanging ears 48 around the top corners of the photovoltaic support panel 4. The tension provided by the steel cable 6 can improve the stability of the overall structure when it is subjected to vibration.

[0045] It should be noted that, in this document, unless otherwise specified, the terms "installation", "connection", etc. should be understood in a broader sense. For example, "connection" can refer to both fixedly connected parts and detachably connected parts. According to the above drawings, ordinary technicians in this field can understand the specific meanings of the above terms according to specific circumstances. In addition, the term "includes" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0046] The above description is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any modification or substitution made by any ordinary technician familiar with the technical field within the technical scope disclosed by the present invention and based on the technical solution and spiritual principles of the present invention shall be covered within the protection scope of the present invention.
