Description

Technical Field

[0001] The utility model relates to the technical field of 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 northern 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 relied on to melt and evaporate under the sun, it will take a long time, which will not only cause the loss of long-term power generation, but also easily freeze the solar photovoltaic panels for a long time, causing greater losses.

[0003] For example, a solar photovoltaic panel snow shielding device with publication number CN220935131U is provided with a push switch, a pressure sensor, a trigger plate, a tilting rod, and a trigger rod, so that when the snow accumulates too much or slides off, the motor can be triggered to start, thereby automatically completing the snow sweeping and snow removal operation. However, the baffle of the device shields the photovoltaic panel from the side, and the shielding effect is relatively general, and some snow will fall on the photovoltaic panel. Therefore, a solar photovoltaic panel snow shielding device is proposed for improvement. Utility Model Content

The controller set on the base frame can cooperate with the rain and snow transmitter to control the dual-axis motor. The photovoltaic panel is set obliquely on the base frame, which is conducive to the photovoltaic panel to absorb solar energy. The rain and snow transmitter melts the snow on snowy days and transmits the electrical signal to the controller based on the principle of liquid conductivity, so that the controller controls the dual-axis motor to work.

The pull rod is used to pull the other end of the cloth-shading cloth, and the slide groove and the slide rail guide the two ends of the pull rod respectively. The two adopt an inverted V-shaped structure, so that when the pull rod drives the cloth-shading cloth to move, an inverted V-shaped shielding structure will be formed, which is convenient for the snow falling on it to slide to both sides. Rollers are set at both ends of the pull rod to improve the smoothness of the pull rod when sliding.

[0014] Preferably, from any of the above schemes, the dual-axis motor is arranged in the middle of the top surface of the mounting plate, and the end of the threaded rod is rotatably connected to the vertical plate fixedly connected to the base frame.

The pull rod drives the cover to unfold and cover the photovoltaic panel to block snow for the photovoltaic panel.

After the snow stops, the controller controls the dual-axis motor to rotate in the opposite direction, and the threaded rod drives the ring to move to both sides. Under the action of the torsion spring, the shield cloth is gradually rolled up on the shield cloth roller, and the accumulated snow falls from the shield cloth to both sides of the photovoltaic panel, automatically completing the snow clearing operation, with better use effect.
