[0006] The protection component comprises a protection shell which is slidably connected to the fixed frame, an exhaust fan is fixedly connected inside the protection shell, and an isolation layer is arranged on the inner wall of the protection shell.

[0007] Preferably, a connecting cable is provided at the other end of the fixing frame, and one end of the connecting cable is electrically connected to the photovoltaic panel.

[0008] Preferably, a slide groove is provided at one end of the protective shell, a slider is inserted into the slide groove, and one end of the slider is fixedly connected to the fixed frame.

[0009] Preferably, the slider is a "T"-shaped structure, and the slider matches the slide groove structure at one end of the protective shell.

[0010] Preferably, a first filter is provided at one end of the exhaust fan, and a second filter is provided at the other end of the exhaust fan.

[0011] Preferably, the protective shell has a right-angled "U"-shaped structure in cross-section, and openings are provided at both ends of the protective shell.

[0012] Preferably, the exhaust fan, the first filter screen and the second filter screen are all distributed at equal intervals laterally with respect to the interior of the protective shell.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) This device can shield and protect the connecting cables at the bottom of the fixed frame, which can not only prevent the connecting cables from being overheated, but also prevent the connecting cables from being damaged, thereby extending the service life of the connecting cables.

[0015] (2) The device is provided with a protective shell at the bottom of the fixed frame. The protective shell can shield the connecting cable. At the same time, the exhaust fan inside the connecting cable can accelerate the flow of air inside the protective shell, thereby accelerating the discharge of heat inside the protective shell through the flow of air, achieving the purpose of heat dissipation and avoiding the temperature of the connecting cable from being too high. The protective shell can also play a certain role in heat preservation in cold weather, thereby ensuring the service life of the connecting cable.

[0016] (3) The device provides a protective shell that can slide horizontally at the bottom of the fixed frame, so that the protective shell not only has a protective function but also facilitates the staff to operate the connecting cables after the protective shell moves.
