[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0024] Reference Figure 1-4 , a cable arrangement structure for photovoltaic power generation, comprising a photovoltaic power generation panel 1, a power supply cable 2 is installed on the photovoltaic power generation panel 1, a protective box 3 is fixed on the photovoltaic power generation panel 1, the bottom surface of the protective box 3 is open, the power supply cable 2 is placed inside the protective box 3, the top surface of the protective box 3 is provided with a first opening 4, the power supply cable 2 passes through the first opening 4, and is connected to the photovoltaic power generation panel 1, the outer surface of the power supply cable 2 and the inner surface of the first opening 4 are fitted with each other, under the action of the protective box 3, rain and snow cannot contact the joint position of the power supply cable 2, this design is conducive to the normal transmission of power by the power supply cable 2, avoids short circuit or corrosion of the power supply cable 2, thereby ensuring the normal operation of the photovoltaic power generation panel 1, in addition, the bottom surface of the protective box 3 is open, the heat generated at the joint position of the power supply cable 2 can be dissipated through the opening of the protective box 3, this design is conducive to the heat dissipation of the power supply cable 2;

[0025] A clamping assembly is provided on the protection box 3, and the clamping assembly includes a second opening 51, a clamping plate 52, a connecting rod 53 and a tension spring 54. The second opening 51 is opened on the side of the protection box 3, and the clamping plate 52 is slidably arranged in the second opening 51. One end of the connecting rod 53 is rotatably installed on one end of the clamping plate 52. One end of the tension spring 54 is connected to the protection box 3, and the other end is connected to the connecting rod 53. A handle 7 is installed on the end of the connecting rod 53 away from the clamping plate 52. Under the elastic force of the tension spring 54, the clamping plate 52 can press the power supply cable 2 and press the power supply cable 2 against the inner surface of the protection box 3. At this time, the clamping plate 52 can play a role of clamping and fixing the power supply cable 2 to prevent the power supply cable 2 from falling off the photovoltaic panel 1;

[0026] A limit assembly is provided on the protective box 3, and the limit assembly includes a limit block 61, a fixing rod 62, a collar 63 and a limit opening 64. The limit block 61 is fixed on the connecting rod 53, one end of the fixing rod 62 is connected to the photovoltaic panel 1, and the other end of the fixing rod 62 is connected to the collar 63. The collar 63 is sleeved on the connecting rod 53, and the outer surface of the connecting rod 53 and the inner circle of the collar 63 fit each other. The limit opening 64 is opened on the collar 63. When the limit block 61 passes through the limit opening 64, the staff rotates the connecting rod 53 again, so that the limit block 61 and the limit opening 64 are misaligned with each other. At this time, the limit block 61 cannot pass through the limit opening 64, and the position of the clamping plate 52 will be fixed. When the clamping plate 52 is fixed, the staff does not need to continue to hold the handle 7 by hand, which provides convenience for the disassembly, inspection and maintenance of the power supply cable 2.

[0027] The specific working principle of the utility model is as follows:

[0028] When the photovoltaic power generation cable arrangement structure proposed by the utility model is in use, the power supply cable 2 is arranged inside the protective box 3, and the protective box 3 can protect the power supply cable 2 to prevent the power supply cable 2 from being exposed. Under the action of the protective box 3, rain and snow cannot contact the joint position of the power supply cable 2. This design is conducive to the normal power transmission of the power supply cable 2, and prevents the power supply cable 2 from being short-circuited or corroded, thereby ensuring the normal operation of the photovoltaic power generation panel 1. In addition, the bottom surface of the protective box 3 is open, and the heat generated at the joint position of the power supply cable 2 can be dissipated through the opening of the protective box 3. This design is conducive to the heat dissipation of the power supply cable 2;

[0029] The protective box 3 is provided with a clamping assembly for the power supply cable 2. Under the elastic force of the tension spring 54, the clamping plate 52 can press the power supply cable 2 and press the power supply cable 2 against the inner surface of the protective box 3. At this time, the clamping plate 52 can clamp and fix the power supply cable 2 to prevent the power supply cable 2 from falling off the photovoltaic panel 1, thereby ensuring the connection stability between the power supply cable 2 and the photovoltaic panel 1. In addition, when the staff needs to disassemble and assemble the power supply cable 2, they first pull the handle 7 so that the handle 7 drives the clamping plate 52 to move through the connecting rod 53. In this process, the staff needs to rotate the connecting rod 53 to align the limit block 61 with the limit opening 64 until the limit block 6 1 passes through the limiting opening 64. When the limiting block 61 passes through the limiting opening 64, one end of the clamping plate 52 can move to the inside of the second opening 51. At this time, the clamping plate 52 no longer blocks the opening position of the protection box 3, which is convenient for the staff to disassemble, inspect and maintain the power supply cable 2. Further, when the limiting block 61 passes through the limiting opening 64, the staff rotates the connecting rod 53 again, so that the limiting block 61 and the limiting opening 64 are misaligned with each other. At this time, the limiting block 61 cannot pass through the limiting opening 64, and the position of the clamping plate 52 will be fixed. When the clamping plate 52 is fixed, the staff does not need to continue to hold the handle 7 by hand, which provides convenience for the disassembly, inspection and maintenance of the power supply cable 2.
