Description

Technical Field

[0001] The utility model mainly relates to the technical field of solar photovoltaic panels, in particular to a solar photovoltaic panel snow shielding device. Background Art

[0002] The ideal working environment for solar power generation is that the solar photovoltaic panels can receive sufficient intensity and duration of radiation. However, in the northern region of my country, especially in high-latitude areas, snowy weather is more frequent. At this time, the solar photovoltaic panels are covered with heavy snow and cannot work. If the heavy snow is melted and evaporated under the sun, it will take a long time, which will not only cause the loss of long-term power generation stagnation, but also easily freeze the solar photovoltaic panels for a long time, causing greater losses. Therefore, it is necessary to protect the solar photovoltaic panels in snowy weather.

[0003] After searching, the utility model patent with announcement number CN211183897U discloses a snow blocking device for photovoltaic solar panels, including a fixed base, fixed pillars are fixedly installed at the four corners of the upper surface of the fixed base by fixing screws, a solar photovoltaic panel is fixedly installed on the upper surface of the four fixed pillars away from the fixed base, an equipment board is fixedly installed on the outer wall of one side of the top of the solar photovoltaic panel, a snow blocking mechanism is fixedly installed on the upper surface of the equipment board, a first-level snow blocking plate is provided at the bottom of the snow blocking mechanism and located on one side of the upper surface of the solar photovoltaic panel, and a second-level snow blocking plate is provided at the bottom of the snow blocking mechanism and located on the other side of the upper surface of the solar photovoltaic panel. The snow blocking device can effectively block snowflakes in heavy snow weather, thereby preventing snowflakes from falling on the solar panel, better protecting the normal use of the solar panel, and has the technical effect of heating and melting snow, good snow melting performance, good performance in use, simple structure, reasonable layout, low manufacturing and maintenance costs, and is suitable for manufacturing, promotion and use.

[0004] In the above patented technical solution, electric heating wires are arranged inside the primary snow guard and the secondary snow guard, and the electric heating wires can be used for heating, so that the accumulated snow can be quickly melted in heavy snow weather, improving the performance, and the servo motor and the threaded rod are arranged to drive the primary snow guard and the secondary snow guard to open and close, so as to achieve the technical effect of snow blocking. However, the above patented technical solution still has the following shortcomings when used:

[0005] 1. In the above patented technical solution, the snow is heated by the electric heating wire to melt the snow quickly. However, after the snow has accumulated for a certain period of time, it has a certain weight. At this time, when the bottom of the snow is heated and melted by the heating wire, it will slide directly from the top of the snow guard. Since general photovoltaic panels are installed at high places such as roofs, the falling snow can easily cause personal safety hazards and property losses to people, seriously affecting people's lives;

[0006] 2. In the above patent technical solution, the first-level snow guard and the second-level snow guard are driven to open and close by the servo motor and the threaded rod. However, since the first-level snow guard and the second-level snow guard have a certain length, when the first-level snow guard and the second-level snow guard are opened and closed to both sides, a large amount of space will be occupied, which leads to a decrease in space utilization. When multiple photovoltaic panels need to be laid at the same time, there will be insufficient space, thereby reducing the practicality of the device.

[0007] Therefore, we provide a solar photovoltaic panel snow shield device to solve the defects in the above solutions. Utility Model Content

Then the user rotates the protective cover to fold it to the left side of the mounting frame, so that the space occupied by the solar photovoltaic panel snow shield can be reduced when in use, thereby improving the practicability of the device.
