[0002] Solar photovoltaic panels are a type of photoelectric semiconductor wafer that uses sunlight to generate electricity directly. Single solar cells cannot be used directly as a power source. To use them as a power source, several single solar cells must be connected in series and parallel and tightly sealed into components. Solar photovoltaic panels are the core part of a solar power generation system and also the most important part of a solar power generation system.

[0003] Solar photovoltaic panels are installed outdoors for use. The surface of the photovoltaic panels is provided with transparent glass, but there is no protective mechanism above the photovoltaic panels.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 3 As shown, it relates to a protective device for installing a photovoltaic panel, including a U-shaped plate 1, two symmetrical straps 2 are fixed to the bottom end of the inner wall of the U-shaped plate 1, a fixing component 3 is provided on one side of the U-shaped plate 1 and below the strap 2, a first opening 101 is opened at the top of the U-shaped plate 1, and a protective glass 5 is provided inside the first opening 101, two supporting plates 4 are fixed to the top of the inner wall of the U-shaped plate 1, a top cover 6 is fixed to the top surface of the U-shaped plate 1, a second opening 61 is opened in the middle of the top cover 6, and an alarm component 8 is installed on the side of the upper surface of the top cover 6.

[0023] like Figure 1-Figure 2 As shown, the lower surface of the butt plate 2 is in contact with the upper surface of the photovoltaic panel.

[0024] When the U-shaped plate 1 is buckled onto the surface of the photovoltaic panel, the strapping plate 2 can support the U-shaped plate 1 .

[0025] like Figure 1-Figure 2 As shown, the fixing assembly 3 includes a screw rod 31 that passes through the U-shaped plate 1 and is threadedly connected to the U-shaped plate 1. One end of the screw rod 31 located in the U-shaped plate 1 is rotatably connected to a pressure plate 32 through a bearing, and the other end of the screw rod 31 is fixedly connected to a knob 33. The pressure plate 32 is fixedly connected to a rubber pad 35 on the side away from the screw rod 31.

[0026] When the U-shaped plate 1 is buckled on the surface of the photovoltaic panel, the screw rod 31 can be moved by rotating the knob 33, and the screw rod 31 pushes the pressing plate 32 to press against the side wall of the photovoltaic panel, thereby achieving fixed installation of the U-shaped plate 1.

[0027] like Figure 1-Figure 2 As shown, a guide rod 34 is fixedly connected to one side of the pressing plate 32 close to the screw rod 31, and the guide rod 34 penetrates the U-shaped plate 1 and is slidably connected to the U-shaped plate 1. The guide rod 34 can guide the movement of the pressing plate 32.

[0028] like Figure 1-Figure 2 As shown, the lower surface of the protective glass 5 is in contact with the upper surface of the support plate 4 , and the side edge of the upper surface of the protective glass 5 is in contact with the inner top wall of the top cover 6 .

[0029] When the top cover 6 is buckled onto the upper surface of the U-shaped plate 1 , the top cover 6 can press the protective glass 5 tightly inside the first opening 101 , thereby achieving fixed installation of the protective glass 5 .

[0030] The side wall of the top cover 6 is penetrated and threadedly connected with a locking bolt 7. The top cover 6 can be fixed to the surface of the U-shaped plate 1 by the locking bolt 7.

[0031] like Figure 1-Figure 3 As shown, the alarm assembly 8 includes an L-shaped plate 81 fixed to the upper surface of the top cover 6, a round tube 82 is fixed to the lower surface of the top end of the L-shaped plate 81, a pressure rod 83 is slidably connected inside the bottom end of the round tube 82, and the bottom end of the pressure rod 83 is in contact with the upper surface of the protective glass 5, a spring 84 is fixedly connected to the top end of the pressure rod 83 and the inner top wall of the round tube 82, a contact switch 85 is fixedly connected to the inner top wall of the round tube 82, and an audible and visual alarm, a battery and a controller are fixed to the upper surface of the L-shaped plate 81.

[0032] The sound and light alarm and the contact switch 85 are both electrically connected to the controller. When the pressure rod 83 no longer presses the contact switch 85, the controller will control the sound and light alarm to sound.

[0033] Working principle: During installation, first buckle the U-shaped plate 1 on the surface of the photovoltaic panel, then turn the knob 33 to drive the pressure plate 32 to move, so that the pressure plate 32 squeezes the side of the photovoltaic panel, thereby achieving the fixed installation of the U-shaped plate 1, and then put the protective glass 5 into the first opening 101 at the top of the U-shaped plate 1, and then cover the top cover 6 on the top of the U-shaped plate 1, use the top cover 6 to press the protective glass 5, and then tighten the locking bolts 7 to fix the top cover 6. In this way, the protective glass 5 can protect the photovoltaic panel itself. When the protective glass 5 is not damaged, the pressure rod 83 will be squeezed by the protective glass 5 and will squeeze the contact switch 85 upward. When the protective glass 5 is broken, the spring 84 pushes the pressure rod 83 downward, and the contact switch 85 is no longer squeezed. The controller will control the sound and light alarm to alarm, reminding the staff in time that the protective glass 5 is damaged, which is conducive to timely replacement.
