[0028] The inverter protection tube in the photovoltaic area needs to be sealed with fireproof mud. However, as time goes by, the covering soil around the inverter cable protection tube will naturally settle, which will cause the cable protection tube to sink and then crack the fireproof mud. Since the cable and inverter terminals are subjected to stress, the cracking of the fireproof mud will not only cause the appearance of the cable and inverter terminals to deform, but also cause the inverter terminals to be subjected to stress, resulting in a short circuit failure, thus posing a safety hazard.

[0030] During the installation process, the connecting mechanism 1 is fixed on the support 5 of the inverter, and then the cross arm 2 is installed on the connecting mechanism 1, and the incoming pipe 3 and the outgoing pipe 4 are fixed on the cross arm 2. The cable on the inverter passes through the incoming pipe 3 and then out of the outgoing pipe 4. In this way, the gravity of the entire cable is applied to the device, reducing the drag force of the cable's own weight on the inverter terminal busbar, avoiding short-circuit faults caused by the cable's own weight and cracking of the fireproof mud, and effectively preventing safety hazards.
[0031] In some embodiments, the connection mechanism 1 is detachably connected to the support 5. In this way, the height of the connection mechanism 1 can be adjusted at any time.
[0032] In some embodiments, the connection mechanism 1 includes a first clamp 10 and a first angle steel 11 . The first clamp 10 is clamped on the pillar 5 , and the first angle steel 11 is connected to both ends of the first clamp 10 .
[0033] Specifically, the first clamp 10 is a U-shaped structure with threads 100 at both ends. The first angle steel 11 is provided with two connecting holes 110 corresponding to the two ends of the first clamp 10. During the installation process, the first clamp 10 is clamped on the pillar 5. After the two ends of the first clamp 10 pass through the two connecting holes 110 on the first angle steel 11, they are tightened on the first clamp 10 with nuts, so that the first clamp 10 and the first angle steel 11 are clamped on the pillar 5. When it is necessary to disassemble or adjust the height of the connecting mechanism 1, the lock nut can be directly loosened.
[0034] Since there are many cables on the inverter, in some embodiments, a plurality of inlet pipes 3 are provided, and each inlet pipe 3 is installed side by side on the cross arm 2. Each cable passes through each inlet pipe 3 in batches.
[0035] In the embodiment shown in the present application, there are 7 inlet pipes 3. Cables are passed through the 7 inlet pipes 3, and then the cables pass through the outlet pipe 4.
[0036] In order to ensure that the cables passing through each inlet pipe 3 can be passed into the outlet pipe 4 , in some embodiments, the diameter of the outlet pipe 4 is larger than the diameter of the inlet pipe 3 .
[0037] In order to facilitate the disassembly and assembly of the connecting mechanism 1 and the cross arm 2 , in some embodiments, the first clamp 10 and the cross arm 2 are detachably connected.
[0038] Specifically, the cross arm 2 is an angle steel structure with two small holes 20 provided on the cross arm 2. Both ends of the first clamp 10 pass through the first angle steel 11 and then through the two small holes 20 on the cross arm 2, and then are tightened by nuts, thereby achieving connection between the first clamp 10 and the cross arm 2.
[0039] In some embodiments, both the inlet pipe 3 and the outlet pipe 4 can be detachably mounted on the cross arm 2. This facilitates the disassembly and assembly of the inlet pipe 3 and the outlet pipe 4.

Similarly, the outlet pipe 4 is also fixed by the second clamp 6. The two ends of the second clamp 6 pass through the through holes 21 on the cross arm 2 and are locked by nuts, thereby fixing the outlet pipe 4.
