The photovoltaic power generation system is mainly composed of solar cell arrays, battery packs, charge and discharge controllers, inverters, AC distribution cabinets, solar tracking control systems and other equipment. These devices work together to convert solar energy into electrical energy and transmit it to various electricity-consuming areas through the power grid.

[0003] During the use of photovoltaic power generation equipment, on rainy days, leaves are easily attached to the surface of the photovoltaic panels through rainwater, blocking the photovoltaic panels and causing hot spots on the photovoltaic panels, which will cause damage to the photovoltaic panels. The photovoltaic power generation equipment in the prior art does not have the function of protecting the photovoltaic panels, which will bring inconvenience to the actual use of the photovoltaic panels.

[0004] Therefore, it is necessary to design a protective structure for photovoltaic power generation to solve the above problems. Utility Model Content

[0022] 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.

[0023] Reference Figure 1-4 A protective structure for photovoltaic power generation, comprising a bracket 1, a photovoltaic panel 2 is mounted on the bracket 1, fixed plates 3 are fixed on both sides of the bottom of the photovoltaic panel 2, a movable moving plate 4 is arranged on the photovoltaic panel 2, a water spray pipe 5 is arranged on the moving plate 4, the water spray pipe 5 is fixed to the side of the moving plate 4 through a pipe rack 6, a plurality of spray holes 7 are opened on the water spray pipe 5, and the plurality of spray holes 7 are arranged toward the photovoltaic panel 2, so that the spray holes 7 can spray water toward the photovoltaic panel 2;

[0024] A driving assembly is provided on the photovoltaic panel 2, and the driving assembly includes a motor 81, a reciprocating screw rod 82 and a guide rod 83. The motor 81 is installed on the photovoltaic panel 2, one end of the reciprocating screw rod 82 is connected to the output shaft of the motor 81, and the other end of the reciprocating screw rod 82 is rotatably installed on one of the fixed plates 3, and the guide rod 83 is fixed on the other fixed plate 3. The reciprocating screw rod 82 passes through one end of the movable plate 4 and is threadedly sleeved with the movable plate 4. The guide rod 83 passes through the other end of the movable plate 4 and is slidably connected with the movable plate 4. When the motor 81 is running, it can drive the reciprocating screw rod 82 to rotate. Under the limiting action of the guide rod 83, when the reciprocating screw rod 82 rotates, it can drive the movable plate 4 to reciprocate on the photovoltaic panel 2.

[0025] The bracket 1 is provided with a water supply assembly, which includes a water tank 91, a plurality of inclined rods 92, an opening 93 and a water pump 94. The water tank 91 is fixed to the bracket 1 through a connecting frame. The water tank 91 is arranged directly opposite to the bottom of the photovoltaic panel 2. The plurality of inclined rods 92 are fixed to the inner surface of the water tank 91, and the plurality of inclined rods 92 are arranged at an angle. The opening 93 is provided on the side of the water tank 91. One end of the plurality of inclined rods 92 passes through the opening 93 and extends to the outside of the water tank 91. The water pump 94 Installed on the water tank 91, the water inlet end of the water pump 94 is connected to the water tank 91, and the water outlet end of the water pump 94 is connected to the water spray pipe 5. When the water pump 94 is running, it can draw the water flow inside the water tank 91 and pump the water flow into the inside of the water spray pipe 5, so that the water flow is sprayed out through a plurality of spray holes 7. Therefore, when the water spray pipe 5 follows the moving plate 4 to move from the top of the photovoltaic panel 2 toward the bottom of the photovoltaic panel 2, the water flow sprayed from the plurality of spray holes 7 can wash the surface of the photovoltaic panel 2.

[0026] The specific working principle of the utility model is as follows:

[0027] When the photovoltaic power generation panel proposed by the utility model is actually used, after rainy weather, the motor 81 is started, and the motor 81 can drive the reciprocating screw 82 to rotate when it is running. Under the limiting effect of the guide rod 83, the reciprocating screw 82 can drive the movable plate 4 to reciprocate on the photovoltaic panel 2 when it rotates. At the same time, the water pump 94 is running. When the water pump 94 is running, it can extract the water flow inside the water tank 91 and pump the water flow into the inside of the water spray pipe 5, so that the water flow is sprayed out through the plurality of spray holes 7. Therefore, when the water spray pipe 5 follows the movable plate 4 to move from the top end of the photovoltaic panel 2 toward the bottom end of the photovoltaic panel 2, the water flow sprayed from the plurality of spray holes 7 can wash the surface of the photovoltaic panel 2, and the washing action can wash off the leaves attached to the surface of the photovoltaic panel 2, so that the leaves fall into the inside of the water tank 91 following the water flow;

[0028] A plurality of inclined rods 92 are fixed in the water tank 91. When leaves follow the water flow into the water tank 91, the leaves will be stopped by the inclined rods 92, and the water flow will flow back to the inside of the water tank 91 through the gaps between the inclined rods 92. Furthermore, the leaves will slide along the inclined inclined rods 92 and fall to the outside of the water tank 91 through the openings 93. The arrangement of the inclined rods 92 can separate the water flow and the leaves, and prevent the leaves from clogging the water pump 94. This design can circulate the water flow, which not only realizes the automatic cleaning of the photovoltaic panel 2, but also saves water resources.

[0029] It is worth noting that the specific start and stop control method of the motor 81 and the water pump 94 is an existing technology and is not an innovative part of the present technical solution. It is not shown in the figure and will not be elaborated on here. Specifically, the motor 81 and the water pump 94 can be automatically started and stopped by sensors, or by remote control of the staff.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
