Description

Technical Field

[0001] The utility model relates to an adjustable photovoltaic solar bracket, belonging to the technical field of photovoltaic brackets. Background Art

[0002] Solar cells, also known as "solar chips" or "photovoltaic cells", are a type of photoelectric semiconductor wafer that uses sunlight to generate electricity directly. Single solar cells cannot be used directly as a power source. Several single solar cells need to be connected in series and parallel and tightly sealed into photovoltaic panels for use as a power source. With the rapid development of the economy, energy supply is becoming increasingly tight. As a new type of energy, the application of solar photovoltaic power generation is expanding. Photovoltaic solar brackets are special brackets designed for placing, installing, and fixing photovoltaic panels in photovoltaic solar systems. They are generally made of aluminum alloy, carbon steel, and stainless steel. Most of today's photovoltaic solar brackets can only adjust the angle of the photovoltaic panel, and are not very convenient for adjusting the height of the photovoltaic panel.

[0003] In view of the problem that the height adjustment of photovoltaic panels on existing photovoltaic solar brackets is not convenient, a Chinese utility model patent with authorization announcement number CN214045538U and authorization announcement date of August 24, 2021 discloses a photovoltaic solar bracket with a stable base, such as Figure 1 and Figure 2 As shown, the photovoltaic solar bracket includes a first device bin 1, a first rotating rod 2 and a movable plate 3. The first rotating rod 2 is inserted transversely on the left side of the first device bin 1 through a bearing. The first rotating rod 2 is connected to other two groups of first rotating rods 2 through a bevel gear. The surfaces of the three groups of first rotating rods 2 are provided with four groups of movable plates 3 through thread sleeves. The bottoms of the movable plates 3 are welded with connecting blocks 4. The bottom ends of the four groups of connecting blocks 4 are respectively hinged with four groups of connecting rods 5. The bottom ends of the four groups of connecting rods 5 are hinged with bases 6. When the user rotates the first rotating rod 2, the four groups of movable plates 3 sleeved on the surface of the first rotating rod 2 move outward or inward while acting on the surface of the first rotating rod 2 through the thread, driving the connecting block 4 to move. Each group of connecting rods 5 rotates on the connecting block 4 and the base 6 around the hinge shafts at both ends to change the height of the first device bin 1, thereby adjusting the height of the photovoltaic panel 7. Although the device can adjust the height of the photovoltaic bracket, during the adjustment process, the first rotating rod 2 of the adjustment device will move up and down, and the operator must change the adjustment position accordingly, which is inconvenient to adjust. Utility Model Content

[0004] The utility model aims to provide an adjustable photovoltaic solar bracket to solve the problem of inconvenient adjustment caused by the non-fixed position of the adjustment device in the prior art.

[0005] To achieve the above purpose, the adjustable photovoltaic solar bracket of the utility model adopts the following technical solutions:

[0007] Furthermore, the screw of the screw-nut mechanism is a forward and reverse screw, and the forward and reverse screws are respectively connected to the lifting columns through two nuts arranged thereon.

[0008] Furthermore, the screw seats of the forward and reverse screws are arranged on a crossbeam, and the crossbeam is connected between the fixed columns corresponding to the two lifting columns.

[0009] Furthermore, a guide groove adapted to the moving stroke of the nut is provided on the crossbeam.

[0010] Furthermore, a side of the fixing column facing the connecting rod is provided with an avoidance hole extending in the vertical direction, and a hinged portion between the connecting rod and the lifting column is located in the avoidance hole.

[0011] Furthermore, a hand wheel is fixed on the lead screw.

[0012] Furthermore, a solid section is provided at the lower end of the fixed column, and the top wall of the solid section limits the lifting column.

[0013] Furthermore, a limiting section is provided in the middle of the forward and reverse lead screws.

[0014] Furthermore, a limiting sleeve is provided on the limiting section.

[0015] Furthermore, the photovoltaic panel mounting base is a support plate.

Since the two movable plates 3 are respectively hinged with one end of the connecting rod 5, and the other end of the connecting rod 5 is hinged with the connecting block 4, and the connecting block 4 is fixed on the lifting column 9, the movement of the movable plate 3 can drive the two connecting blocks 4 to slide up and down in the avoidance hole 16 at the same time, thereby driving the lifting column 9 to extend and retract in the fixed column 8, and finally adjusting the height of the photovoltaic panel 7 fixedly connected to the lifting column 9. The utility model fixes the hand wheel 13 on the lead screw 11, and the lead screw 11 is assembled on the fixed column 8. When the hand wheel 13 is rotated, the position of the hand wheel 13 always remains fixed and will not change with the height change of the photovoltaic panel 7. Such a design makes adjustment convenient and easy to control the adjustment amount.
