Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic engineering, in particular to a distributed adjustable photovoltaic bracket for a highway. Background Art

[0002] In order to accelerate the development of green transportation networks and promote the transformation of transportation networks towards low-carbon and energy-saving directions, a number of environmental protection technologies and new energy utilization technologies will be applied to highway construction and renovation. For example, photovoltaic power generation technology can be applied to plateau highways.

[0003] The air on the plateau is thin and the atmosphere has little interference with sunlight, so solar energy resources are very abundant. Although photovoltaic panels prefer strong light, their power generation efficiency is highest at low and normal temperatures. The low temperature and high altitude environment of the plateau is conducive to improving the efficiency of photovoltaic power generation.

[0004] However, most of the plateau soil belongs to the permafrost layer, which has rheological properties and its long-term strength is much lower than the instantaneous strength characteristics. Therefore, when building photovoltaic brackets in permafrost areas, two major dangers must be faced: frost heave and thaw settlement. The existing photovoltaic brackets are usually directly inserted into the ground. When the seasons change, the photovoltaic brackets may tilt and invert the photovoltaic panels, causing immeasurable losses.

[0005] To this end, we propose a distributed adjustable photovoltaic support for highways. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] See also Figure 1-4 The utility model provides a technical solution: a distributed adjustable photovoltaic bracket for highways.

[0022] include:

[0023] A photovoltaic panel housing 10, the top of which is used to place a photovoltaic panel;

[0024] A fixing rod 20, the fixing rod 20 is arranged on the lower side of the photovoltaic panel housing 10, and the fixing rod 20 is used to fasten the soil;

[0025] The adjusting mechanism 30 is arranged between the photovoltaic panel shell 10 and the fixing rod 20. The adjusting mechanism 30 can cooperate with the fixing rod 20 to adjust the inclination angle of the photovoltaic panel shell 10 in different seasons. The photovoltaic panel shell 10 is fixed to the ground by the fixing rod 20. The fixing rod 20 can be fastened to the nearby permafrost layer, so that the photovoltaic panel shell 10 can be firmly set on the ground. At the same time, the adjusting mechanism 30 can adjust the angle of the photovoltaic panel shell 10 according to the changes in summer and winter, so as to increase the photovoltaic panel to capture more sunlight.

[0026] A cavity is provided in the fixing rod 20, and liquid nitrogen 21 is stored in the fixing rod 20. The bottom of the fixing rod 20 is a working piece 22, and the bottom of the fixing rod 20 is inserted into the frozen soil layer. The middle part of the fixing rod 20 is an insulating piece 23, and the top of the fixing rod 20 extends out of the ground as a heat sink 24. The top outer wall array of the fixing rod 20 is provided with a heat sink 25. When the temperature of the working piece 22 at the bottom of the fixing rod 20 is higher than the heat sink 24 in winter, the liquid nitrogen 21 will absorb the heat of the frozen soil and vaporize and rise, and then heat exchange through the heat sink 25 outside the heat sink 24, so as to form a liquid and return to the working piece 22, and the cycle is repeated. In this process, the liquid nitrogen is converted from liquid to gas, transfers heat and maintains the stability of the frozen soil layer. With this design, the photovoltaic panel shell 10 on the top of the fixing rod 20 will not tilt, thereby ensuring the stability of the photovoltaic panel in receiving sunlight.

[0027] The adjusting mechanism 30 includes a fixing rod 31, which is L-shaped. One end of the fixing rod 31 is fixedly connected to the outer wall of the fixing rod 20, and the other end of the fixing rod 31 is rotatably connected to the photovoltaic panel shell 10. A lifting mechanism 32 is arranged between the photovoltaic panel shell 10 and the fixing rod 20. The fixing rod 20 cooperates with the lifting mechanism 32 and the adjusting mechanism 30, so that the fixing rod 31 can be used as the axis to rotate the photovoltaic panel shell 10, and then the photovoltaic panel shell 10 is adjusted to a suitable angle, so that the photovoltaic panel can capture more sunlight.

[0028] The lifting mechanism 32 includes a lifting rod 321, a rotating member 322 is provided on the top of the lifting rod 321, and the rotating member 322 abuts against the lower side of the photovoltaic panel shell 10, the lifting rod 321 is slidably connected to the fixing rod 20, and a closed ring 323 is provided at the bottom of the lifting rod 321. In winter, the liquid nitrogen in the fixing rod 20 becomes gaseous under the influence of temperature, so that the air pressure in the fixing rod 20 increases, thereby pushing the lifting rod 321 to rise upward, and the closed ring 323 at the bottom of the lifting rod 321 can prevent the liquid nitrogen in the fixing rod 20 from escaping from the fixing rod 20 during the vaporization process. The rotating member 322 at the top of the lifting rod 321 can rotate the photovoltaic panel shell 10 with the axis of the fixing rod 31 as the center from the bottom of the photovoltaic panel shell 10. The height of the sun is higher in summer and lower in winter. Therefore, the photovoltaic panel shell 10 is lifted up by the lifting rod 321 in winter, so that the photovoltaic panel can capture more sunlight in winter.

[0029] The top outer wall of the fixed rod 20 is provided with a limiting piece 41, and the limiting piece 41 is fixedly connected to the outer wall of the fixed rod 20. The upper outer wall of the lifting rod 321 is provided with a thread, and the outer wall of the lifting rod 321 is threadedly connected with an adjusting piece 42. There are two adjusting pieces 42. When the lifting rod 321 moves upward along the fixed rod 20, the adjusting piece 42 abuts against the limiting piece 41 when it moves to a certain position. When the lifting rod 321 moves downward along the fixed rod 20, the lower adjusting piece 42 abuts against the top of the fixed rod 20. With this design, the staff can adjust the lifting rod 321 according to the specific local latitude and climate conditions. As for the installation position of the photovoltaic panel, the inclination angle in summer can be set to 0.93 times the dimension minus 21 degrees, which can be achieved by adjusting the adjusting piece 42 on the lower side of the lifting rod 321. By rotating the adjusting piece 42, when the lifting rod 321 moves downward in summer, the adjusting piece 42 is adjusted to a suitable angle when it abuts against the top of the fixing rod 20. In winter, it is 0.875 times the dimension plus 19.2 degrees. By adjusting the position of the adjusting piece 42 at the top of the lifting rod 321 on the lifting rod 321, the angle when the adjusting piece 42 abuts against the limit piece 41 when the lifting rod 321 rises can be just right.
