Description

Technical Field

[0001] This invention relates to an adjustable torsion spring current guide compatible with multiple specifications of photovoltaic modules. Background Technology

[0002] The most common problem on the surface of photovoltaic modules is water and dust accumulation, especially after rain, when the height difference between the bottom frame of the module and the glass causes water and dust to accumulate. This is not only common in ground-mounted power stations, but also more serious in rooftop distributed photovoltaic systems because of the smaller installation angle.

[0003] In rooftop distributed photovoltaic projects, we often see a large amount of dust accumulating at the bottom edge of the modules. In severe cases, this dust can cover the bottom row of solar cells, affecting local power generation. The localized shading caused by dust accumulation is the main reason for the impact on power generation and the formation of hot spot effects, while uniform dust accumulation on the surface is a secondary reason. This is because the dust accumulation creates shading bands of varying thickness and width, resulting in different degrees of shading for the photovoltaic modules.

[0004] Field tests have shown that uniform surface dust on photovoltaic modules does not cause hot spot effects. Dust accumulated over 20 days affects power generation by only 12%, thus the impact is relatively low. However, dust accumulation after rain causes hot spot effects, increasing the impact on power generation to 36%.

[0005] This device enables the module to guide water and remove dust. Currently, some metal guides can achieve this function. However, the current guiding capacity of existing metal guides is limited and cannot meet the increasingly stringent requirements of photovoltaic modules. Furthermore, existing metal guides are often installed at a specified thickness and lack universality. Summary of the Invention

[0006] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adjustable torsion spring current guide that is compatible with multiple specifications of photovoltaic modules.

[0007] An adjustable torsion spring current guide compatible with multiple specifications of photovoltaic modules includes a tubular snap-fit ​​side and a sheet snap-fit ​​side connected by a snap-fit ​​method;

[0008] The tubular snap-fit ​​side is an integral torsion spring structure, including a vertical part connected to the sheet snap-fit ​​side and a horizontal part for guiding flow.

[0009] The horizontal section includes two symmetrically designed flow guide sections. Each flow guide section includes a water intake column, a hydrophilic bend, and a vertically arranged water guide column. Adjacent water intake columns are connected by a hydrophilic bend, and the tail of the water intake column is connected to the water guide column.

[0010] The inner side of the vertical section is provided with several sets of notches, which cooperate with the spring pieces on the side of the sheet-like buckle.

[0011] In order to further destroy the surface tension of the water surface, the hydrophilic elbow is inclined to the inner side of the photovoltaic module.

[0012] In order to better clamp the flow guide on the photovoltaic module, the bottom of the sheet-shaped buckle side is connected with a clamping tongue, and the clamping tongue comprises an arc-shaped transition.

[0013] In order to realize the adaptation of photovoltaic modules with different thicknesses, the surface of the sheet-shaped buckle side is provided with a spring sheet, which is popped inward by half-cut processing and forms a connection with the notch on the tubular buckle side. In use, if the thickness of the photovoltaic module is thin, the bottom notch can be used for connection, and if the thickness of the photovoltaic module is thick, the notch at the top can be used for connection.

[0014] Further, the material of the tubular buckle side is stainless steel.

[0015] In order to improve the smoothness of clamping and realize the adjustment of thickness, the notches on the tubular buckle side are formed by stamping, and the shape of the notches is a plurality of arc curves connected together, wherein the curvature of the upper curve is greater than the curvature of the lower curve.

[0016] Further, the sheet-shaped buckle side comprises two pieces of stainless steel spring sheets connected together, and the stainless steel spring sheets are connected by an arc-shaped sheet-shaped part.

[0017] Further, the distance between the two pieces of stainless steel spring sheets is matched with the diameter of the tubular buckle side. Advantages

[0018] 1. The device is a torsion spring structure made of metal material through bending, stamping and other processes, which has a certain connection and fixing function, and the integrated forming process can greatly improve the processing efficiency, save processing cost and prolong the service life of the device.

[0019] 2. The device has strong water guiding capacity, and the hydrophilic elbow extends inward to effectively destroy the surface tension of the water surface, so as to effectively drain the water along the water guide column and the water guide column, and effectively improve the water accumulation on the surface of the photovoltaic module, so as to ensure the effective and stable operation of the photovoltaic module.

[0020] 3. The device is an integrated forming structure, and is made of a material with strong elastic deformation capacity. In use, the material can form clamping on the photovoltaic module through its own elastic force, which can reduce the use of auxiliary mechanisms and reduce costs. BRIEF DESCRIPTION OF DRAWINGS

[0026] In order to deepen the understanding of the present application, the present application will be further described in conjunction with the embodiments and the accompanying drawings, which are only used to explain the present application and do not constitute a limitation on the protection scope of the present application.

[0027] As Figures 1-3 shown, an adjustable and compatible multi-specification photovoltaic module torsion spring flow guide comprises a tubular buckle side 2 and a sheet-shaped buckle side 1 connected by clamping;

[0028] The tubular buckle side 2 is an integral torsion spring structure, comprising a vertical part connected with the sheet-shaped buckle side and a horizontal part for flow guide, as Figure 2 shown, the integral tubular buckle side 2 is formed by effective bending processing of a single stainless steel pipe, having good elastic deformation capacity and providing better connection strength when clamped.

[0029] The horizontal part comprises two symmetrical flow guide parts, each of which comprises a water guide column 21, a hydrophilic elbow 23 and a vertically arranged water guide column 22, and the adjacent two water guide columns are connected by the hydrophilic elbow 23, and the tail of the water guide column 21 is connected with the water guide column 22.

[0030] The inner side of the vertical part is provided with a plurality of groups of notches, and the notches 24 are matched with the spring sheets 11 on the sheet-shaped buckle side. When applied to photovoltaic modules of different thicknesses, different height notches can be used for connection, thereby realizing adjustable setting in the thickness direction.

[0031] As Figure 2 shown, the hydrophilic elbow is inclined to the inner side of the photovoltaic module, and this design can better break the surface tension of the water surface in use, thereby more conveniently guiding the water out.

[0032] The sheet-shaped buckle side 1 is made of elastic stainless steel sheet, which has certain elasticity in the buckled state, so that the flow director can be buckled on the lower frame of the assembly. The two parallel iron sheets are bent to achieve smooth torsion spring column between the sheet metal parts. After the sheet-shaped buckle side 1 is connected with the tubular buckle side 2, the assembly frame can be clamped.

[0033] In actual use, the tubular buckle side 2 can be made of a whole stainless steel wire, a stainless steel pipe or a common thin strip-shaped metal product. In theory, any existing variable wire or strip with certain strength and toughness on the market can be used.

[0034] The hydrophilic elbow 23 is used for the composition of the overall structure and the realization of the water guide function in actual use. Any other structure can be used as a degenerate design of the application, and thus falls within the protection scope of the application.

[0035] The above description is only a preferred embodiment of the application and is not intended to limit the application. Any modification, equivalent replacement, improvement, etc. within the spirit and principles of the application shall be included in the protection scope of the application.
