DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention and are not used to limit the present invention.

[0023] Example: Figure 1-4As shown, the utility model provides a technical solution, a wear-resistant and bend-resistant photovoltaic line, including a core 1, an insulating layer 2 is sleeved on the surface of the core 1, a shielding layer 3 is installed on the surface of the insulating layer 2, an inner shaping layer 4 is sleeved on the surface of the shielding layer 3, a buffer layer 5 is sleeved on the surface of the inner shaping layer 4, and a thermal insulation layer 6 is bonded to the surface of the buffer layer 5. The buffer layer 5 is a buffer rubber, and the thermal insulation layer 6 is made of polyurethane material. Through the use of the buffer layer 5, the interior of the photovoltaic line is buffered and protected, and the pressure caused by the collision and extrusion of foreign objects outside is reduced, while the thermal insulation layer 6 protects the photovoltaic line from the impact of foreign objects. It plays the role of heat insulation and heat preservation to prevent the external high temperature from affecting the core 1. The surface of the insulation layer 6 is sleeved with an outer plastic layer 7, and the surface of the outer plastic layer 7 is sleeved with a protective layer 8. The protective layer 8 is made of rubber extrusion and wrapped. The surface of the protective layer 8 is sprayed with waterproof paint and reflective paint in sequence. One end surface of the protective layer 8 is equidistantly provided with movable grooves 9 along the circumferential direction, and the other end surface of the protective layer 8 is equidistantly provided with splicing grooves 10 along the circumferential direction. The surface of the protective layer 8 is sleeved with a movable rubber sleeve 11 at the corresponding position of the movable groove 9. The inner wall of the movable rubber sleeve 11 is equidistantly provided with a splicing groove 10 along the circumferential direction. The distance between the fixed installation and the splicing card strip 12 is the same. The number of the movable groove 9, the splicing groove 10 and the splicing card strip 12 are the same, and the positions correspond to each other. The splicing card strip 12 is movably connected to the inside of the movable groove 9. Annular grooves 13 are symmetrically provided at both ends of the surface of the movable rubber sleeve 11. Elastic locking strips 14 are embedded in the two annular grooves 13. One end of the elastic locking strip 14 is symmetrically fixedly connected to a pull block 15. The elastic locking strip 14 is tightly pressed against the surface of the movable rubber sleeve 11. A through hole is provided in the middle of the pull block 15. The splicing card strip 12 and the movable rubber sleeve 11 are both hard rubber. The elastic locking strip 14 is an elastic rubber strip. The movable groove 9 and the splicing groove 10 are used in conjunction to facilitate the movement of the movable rubber sleeve 11. When the two photovoltaic cables are connected, it is pushed to move to the surface of the connection, which plays a role in covering and protecting the photovoltaic line connection, preventing the photovoltaic line connection from being directly exposed to the outside and easily damaged. The two elastic locking strips 14 can be pressed tightly against the surface of the two photovoltaic lines respectively, which has a certain stabilizing effect, so that the connection will not fall off easily. The elastic locking strip 14 can be stretched by the pull block 15, which is convenient for adjusting the position during installation and movement;

[0024] The surface of the protective layer 8 is provided with expansion gaps 16 at equal intervals, and the surface of the protective layer 8 is provided with wear-resistant protrusions 17 at equal intervals on one side of the expansion gaps 16. The depth of the expansion gaps 16 is half the thickness of the protective layer 8, and the wear-resistant protrusions 17 and the expansion gaps 16 are staggered on the surface of the protective layer 8. The coordinated use of the protective layer 8 and the expansion gaps 16 protects the surface of the photovoltaic wire, and the expansion gaps 16 are more convenient for bending and deformation, providing a certain degree of ductility, thereby preventing the photovoltaic wire from being bent and deformed for a long time, which aggravates its surface aging and cracking. At the same time, the use of the wear-resistant protrusions 17 improves the wear resistance of the photovoltaic wire surface, reduces friction in other positions, and improves the service life of the photovoltaic wire.

[0025] The working principle and usage process of the utility model are as follows: First, when installing the photovoltaic line, it is necessary to connect the two photovoltaic lines. The staff brings the ends of the two photovoltaic lines close together and connects and fixes the core 1 to each other. At this time, the ends of the two photovoltaic lines are aligned, and the movable rubber sleeve 11 on the surface of one end of the photovoltaic line is close to the position of the splicing groove 10 on the surface of the other photovoltaic line. The positions of the movable groove 9 and the splicing groove 10 correspond to each other. The elastic locking strip 14 is pulled outward by the pull block 15 to make it elastically extend. The staff expands it outward, loosens the squeeze and lock of the movable rubber sleeve 11, and pulls The movable rubber sleeve 11 is pushed along the movable groove 9, and the splicing card strip 12 moves along the movable groove 9 to the inside of the splicing groove 10 on the surface of the other photovoltaic wire. Then, the movable rubber sleeve 11 is moved and sleeved on the surface of the connection between the two photovoltaic wires. The elastic locking strip 14 is loosened so that it is tightly attached to the inside of the annular groove 13. The two elastic locking strips 14 are respectively pressed against the surfaces of the two photovoltaic wires, which plays a role of squeezing and locking the movable rubber sleeve 11. Then, the movable rubber sleeve 11 covers and protects the connection between the two photovoltaic wires, so that the connection is not exposed to the outside and will not fall off easily.

[0026] When installing the photovoltaic wire, the position where it needs to be bent is adjusted at the expansion gap 16. The photovoltaic wire is bent so that the expansion gap 16 at the corresponding position expands and extends. The photovoltaic wire has a certain bending resistance and will not easily cause damage to its surface after bending. At the same time, the wear-resistant protrusions 17 are in contact with the installation plane. When pulling and traction, the wear-resistant protrusions 17 play a wear-resistant protection role to prevent the cable surface from being worn. When the photovoltaic wire is in use, the buffer layer 5 plays a buffer protection role. When external foreign objects collide and squeeze, it absorbs the pressure generated by the extrusion. At the same time, the thermal insulation layer 6 plays a role of heat insulation to prevent the core 1 from being affected by external high temperatures.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
