Description

Technical Field

[0001] The utility model relates to the field of solar street lamps, in particular to a solar street lamp suitable for snow seasons. Background Art

[0002] Solar street lights are powered by crystalline silicon solar cells, use maintenance-free valve-controlled sealed batteries to store electrical energy, use ultra-bright LED lamps as light sources, and are controlled by intelligent charge and discharge controllers to replace traditional public electric lighting street lights.

[0003] The Chinese patent with publication number CN219867512U discloses a solar street light. In order to solve the problem that the snow on the surface of the solar panel is easy to freeze and affect the operation of the solar panel in snowy days, mounting seats are arranged on both sides of the solar panel, and second fixing bars are installed on the top surface of the mounting seats. A heating tube is installed between the two groups of second fixing bars, and the heating tube is located above the solar panel, and the heating tube does not contact the solar panel, thereby avoiding damage to the solar panel when the heating tube is heated. When the snow gathers and freezes on the surface of the solar panel, the heating tube is controlled by an external controller to heat it, so that the snow on the surface of the solar panel melts and the solar panel can be used normally.

[0004] In short, the above-mentioned prior art is to arrange a number of heating tubes at intervals on the upper side of the solar panel. When snow covers the surface of the solar panel, the heating tubes distributed on the upper side of the solar panel release heat to melt the snow, so that the solar panel can be restored to use. However, although the several heating tubes arranged at intervals can release heat at multiple points on the upper surface of the solar panel to melt the snow, they will also block the light on the solar surface. When the sunlight is not directly on the surface of the solar panel, the resulting streaks will block a large area on the surface of the solar panel. In order to solve the above problems, we propose a solar street light suitable for the snow season. Utility Model Content

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0020] See also Figure 1-3 The figure shows a preferred embodiment of the utility model, a solar street light suitable for snow season, including a street light body 1, a solar panel 2 is arranged on the top of the street light body 1, a U-shaped mounting frame 3 is fixedly installed on the outer side of the solar panel 2, the opening direction of the mounting frame 3 is adapted to the direction of the lower side of the solar panel 2, a heat preservation cover 4 is fixedly installed on the upper back side of the mounting frame 3 near the high point direction of the solar panel 2, an annular heating tube 5 is fixedly installed inside the mounting frame 3 and the heat preservation cover 4, the interior of the mounting frame 3 and the heat preservation cover 4 are connected, and a transverse groove 6 is opened on the outer wall of the heat preservation cover 4 near the upper surface of the solar panel 2.

[0021] Specifically, a U-shaped heat absorption tube 7 is fixedly installed inside the installation frame 3, and the interior of the U-shaped heat absorption tube 7 is filled with antifreeze 8. It should be added that the U-shaped heat absorption tube 7 is made of metal with good thermal conductivity. When the annular heating tube 5 is heating, it can absorb heat and transfer the heat to the outside of the solar panel 2 through the antifreeze 8 filled inside. The antifreeze 8 will not freeze at will, thereby avoiding damage to the U-shaped heat absorption tube 7.

[0022] Among them, the thickness of the installation frame 3 exceeds the thickness of the solar panel 2, so that the water melted by the heat of the annular heating tube 5 on the upper side of the solar panel 2 can flow down along the surface of the solar panel 2, so that the heat can be fully utilized. The inner wall of the installation frame 3 is provided with air holes 9 on the upper side of the solar panel 2 for the internal heat of the installation frame 3 to be released to the upper side of the solar panel 2.

[0023] In addition, a gas flow gap is provided inside the installation frame 3 between the U-shaped heat absorbing tube 7 and the air vent 9, providing space for the formation of natural convection of airflow, thereby further improving the heat utilization efficiency.

[0024] It should be noted that a drainage hole is provided near the low point on the lower surface of the mounting frame 3 for draining the snow water flowing into the air vent 9.

[0025] Among them, a groove matching the size of one end of the transverse groove 6 is opened on the inner side of the U-shaped heat absorption tube 7 to facilitate the lower end of the transverse groove 6 to extend into the installation frame 3.

[0026] The inner wall of the installation frame 3 is provided with a heat-insulating layer to reduce heat loss and improve heat utilization efficiency.

[0027] In this embodiment, when the accumulated snow condenses and freezes on the surface of the solar panel 2, before the street lamp body 1 is charged by solar energy, the annular heating tube 5 is controlled by the external controller to start. The heat generated by the annular heating tube 5 is transmitted to the upper side of the solar panel 2 through the transverse groove 6 to melt the snow water. The heated snow water can also slide down naturally along the slope of the solar panel 2. During the process, it is blocked by the installation frame 3 and will not fall out of the solar panel 2, so that the heat can be fully absorbed. After the top of the solar panel 2 is exposed, a part of the charging effect can be restored, forming a positive cycle, and the power in the battery will not be exhausted.

[0028] On the other hand, the heat released by the annular heating tube 5 is absorbed by the U-shaped heat absorption tube 7 and transferred through the antifreeze 8, finally heating the gas and removing the snow on the upper side of the solar panel 2 from the outside of the solar panel 2, thereby restoring the use of the solar panel 2.

[0029] Finally, it should be noted that in the description of the present invention, it should be noted that the terms "vertical", "up", "down", "horizontal", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings.
