[0002] The combined solar photovoltaic accessory refers to a comprehensive design that integrates components with functions of installation, electrical connection, and performance optimization. These accessories are designed to simplify the installation process of the solar system while improving the efficiency and reliability of the system.

[0003] In the existing combined solar photovoltaic accessories, when the photovoltaic panel converts solar energy into electrical energy, an inverter is required to convert the direct current generated by the photovoltaic panel into alternating current for subsequent transmission and storage. A reactor is needed during transmission to ensure that the high-order harmonics have less impact on the transmitted alternating current. However, when the existing reactor is connected to the inverter through a cable, since the existing equipment is not firmly fixed when using the cable connection, the vibration generated during the operation of the equipment will cause the cable to fall off, resulting in an impact on the anti-interference effect of the electromagnetic field.

[0004] Therefore, we provide a combined solar photovoltaic accessory with anti-interference function to solve the above problems. Content of the Utility Model

[0005] The purpose of the utility model is to provide a combined solar photovoltaic accessory with anti-interference function. Through the cooperation of the positioning component and the anti-interference component, it solves the problem that the cable connection between the reactor and the inverter in the existing combined solar photovoltaic accessory is unstable and easily affects the anti-interference effect on the cable.

[0006] To solve the above technical problems, the utility model is realized through the following technical solutions:

Specific Embodiment Two

[0031] Please refer to Figures 1-4 , on the basis of Specific Embodiment One, the buffer member includes an arc-shaped sleeve 12. The arc-shaped sleeve 12 is fixedly connected to one end of the telescopic rod 8. A damper 13 is fixedly connected to the bottom of the front of the arc-shaped sleeve 12. One end of the damper 13 is fixed to the front of the inner cavity of the positioning frame 4. A wire passing hole 14 is opened at the front end of the inner cavity of the end plate 3. A pipe sleeve 15 is fixedly communicated with the bottom of the inner cavity of the wire passing hole 14. One end of the bidirectional lead screw 5 is fixedly connected with an insulating handwheel 16. A limit pin is threadedly connected to the top of the inner cavity of the insulating handwheel 16. A limit rod 17 is fixedly connected to one side of the inner cavity of the positioning frame 4. The surface of the limit rod 17 is slidably connected to one side of the inner cavity of the sliding sleeve 6. Mounting plates 18 are fixedly connected to both sides of the insulating steel block 2. An installation opening is opened on one side of the inner cavity of the mounting plate 18. A bolt 19 is threadedly connected to the inner cavity of the installation opening. A connection opening is opened at the top of the inner cavity of the positioning frame 4. The surface of one side of the connection opening is slidably connected to the surface of the arc-shaped sleeve 12.

[0032] Specifically: One end of every two telescopic rods 8 is fixed to the back of the arc-shaped sleeve 12. The arc-shaped sleeve 12 is made of rubber, which can play an insulating role and protect the surface of the cable 9. The damper 13 can slow down the vibration received by the cable 9 to prevent the connection between the cable 9 and the reactor 1 or the inverter from being disconnected. Dampers 13 are fixedly connected to the bottom of the front end and the bottom end of the rear end of the inner cavity of the positioning frame 4. One end of the damper 13 is fixed to the bottom of the back of the arc-shaped sleeve 12;

[0033] The pipe sleeve 15 can protect the contact between the surface of the cable 9 and the wire passing hole 14 of the end plate 3. The limit pin can limit the insulating handwheel 16. The limit rod 17 is fixed on the right side of the inner cavity of the positioning frame 4. By sliding the inner side of the sliding sleeve 6 on the surface of the limit rod 17, a limiting effect can be produced on the movement of the sliding sleeve 6. The reactor 1 can be fixed through the installation opening and the bolt 19 on the surface of the mounting plate 18. The surface of one side of the connection opening is slidably connected to the arc-shaped sleeve 12 to facilitate the positioning of the cable 9, and the rubber arc-shaped sleeve 12 can protect the cable 9.

[0034] The working principle of the present utility model is as follows: When using the anti-interference combined solar photovoltaic accessories, first connect one end of the cable 9 to the output end of the external inverter, and the other end extends out through the connection port at the top of the inner cavity of the positioning frame 4 and the wire passing hole 14 at the front end of the inner cavity of the end plate 3 and is connected to the coil on the surface of the anti-electrical appliance. Then, take out the limit pin and rotate the insulating handwheel 16. The insulating handwheel 16 drives the bidirectional lead screw 5 to rotate. The bidirectional lead screw 5 drives the two sliding sleeves 6 to move relatively. The movement of the sliding sleeve 6 drives the connecting plate 7 to move. The connecting plate 7 drives the telescopic rod 8 to move. The telescopic rod 8 drives the arc-shaped sleeve 12 to move. The two arc-shaped sleeves 12 move relatively to position the surface of the cable 9.

[0035] Then, when the external inverter converts the direct current of the photovoltaic panel into alternating current and transmits the alternating current to the reactor 1 through the cable 9, the copper mesh 11 is used to provide electromagnetic shielding to reduce the influence of external electromagnetic interference on the internal signal of the cable, and the filter 10 can effectively filter out electromagnetic interference signals to maintain the stability of the circuit. When the inverter and the reactor 1 vibrate during operation, to prevent the cable 9 from loosening from the connection port, when the device vibrates, the arc-shaped sleeve 12 in the inner cavity of the positioning frame 4 is in close contact with the surface of the cable 9, and the received vibration will be transmitted from the arc-shaped sleeve 12 to the surface of the damper 13. The damper 13 slows down the received force to ensure the stability of the cable 9 and enhance the anti-interference ability during current transmission.
