[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] Please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of a photovoltaic line provided by a specific embodiment of the present invention; Figure 2 A schematic structural diagram of a photovoltaic line applied to a color steel tile roof provided in a specific embodiment of the present invention.

[0021] A photovoltaic wire suitable for a color steel tile roof provided in an embodiment of the present invention includes: an outer diameter of a preset section on the photovoltaic wire 1 close to a photovoltaic connector 3 is larger than the outer diameter of the photovoltaic connector 3. Specifically, the outer shape of the photovoltaic wire 1 in the preset section can be changed so that the deformed outer diameter is larger than the outer diameter of the photovoltaic connector 3. The end of the photovoltaic wire 1 is led out from the middle of the preset section for connection with the photovoltaic connector 3. Since the photovoltaic wire 1 is led out from the middle of the preset section with a larger outer diameter, after the photovoltaic connector 3 is connected, the photovoltaic connector 3 will be in a suspended state to avoid the photovoltaic connector 3 overlapping the color steel tile roof 4, thereby ensuring a safe distance for arcing.

[0022] Specifically, the preset section is a spiral structure 2 formed by the photovoltaic wire 1, and the end of the photovoltaic wire 1 is led out from the middle of the spiral structure 2, wherein the outer diameter of the preset section can be made larger than the photovoltaic connector 3 by spirally deforming the preset section of the photovoltaic wire 1.

[0023] It should be noted that the cross-sectional shape of the spiral structure 2 can be circular, or can be a polygonal structure such as a triangle, a quadrilateral, or other special-shaped structures. The core of this embodiment is that the outer diameter of the spiral structure 2 is larger than the outer diameter of the photovoltaic connector 3. Regarding the shape of the spiral structure 2, this application does not make any specific restrictions, and the specific shape can be selected according to actual conditions.

[0024] The spiral structure 2 is preferably a multi-turn spring built into the photovoltaic line 1. For example, two turns of springs can be arranged in the photovoltaic line 1. The multi-turn spring can improve the support stability of the spiral structure 2 and prevent the problem of overturning.

[0025] In order to optimize the use effect of the spiral structure 2 in the above embodiment, in this embodiment, the spring is a spring with adjustable outer diameter. For example, the outer diameter of the single-turn spring can be increased by reducing the number of spring turns of the spiral structure 2 to adapt to the photovoltaic connector 3 with a larger outer diameter. Of course, the outer diameter of the spring can also be reduced to adapt to the photovoltaic connector 3 with a smaller outer diameter.

[0026] In order to achieve the purpose of double insurance, a support plate is provided on the outside of the lead-out end of the spiral structure 2, and the outer diameter of the support plate is larger than the outer diameter of the photovoltaic connector 3. When the spiral structure 2 loses its supporting function, the photovoltaic connector 3 can be suspended by the support plate, wherein the support plate is preferably installed on the photovoltaic line 1 in a detachable connection manner.

[0027] Furthermore, a support portion is provided inside the spiral structure 2. When the external structure of the spiral structure 2 is prone to change, the support portion can shape the spiral structure 2. For example, the support portion can be a cylindrical structure, and a preset section of the photovoltaic line 1 can be wrapped around the outside of the support portion and fixed, but the end of the photovoltaic line 1 still needs to be led out from the central axis area of ​​the cylinder; when the spiral structure 2 is an irreversible structure or the external structure is relatively stable, the support portion may no longer be provided inside the spiral structure 2.

[0028] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0029] The above is a detailed introduction to a photovoltaic line suitable for a color steel tile roof provided by the present invention. This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core idea. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the present invention, several improvements and modifications can be made to the present invention, and these improvements and modifications also fall within the scope of protection of the claims of the present invention.
