Technical Field

[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to an adjustable photovoltaic bracket for special-shaped roofs. Background Technique

[0002] A photovoltaic panel is a power generation device that converts solar energy into electrical energy. Its working principle is based on the photovoltaic effect. The photovoltaic panel converts sunlight into direct current through solar cells, and then converts the direct current into alternating current for power supply through an inverter. During installation, the photovoltaic panel is supported and fixed by a photovoltaic bracket.

[0003] For example, the Chinese authorized patent (Column base of photovoltaic bracket and photovoltaic bracket) with the publication number CN219107336U: includes a column base plate; a column sleeve, the column sleeve is a hollow structure, the first end of the column sleeve is connected to the column base plate, and the second end of the column sleeve is used for the column of the photovoltaic bracket to extend into the column sleeve and be installed in the column sleeve. This column base prefabricates the originally complex rigid column footing in the factory. After arriving at the site, the column base and the column are directly assembled and installed, reducing the construction complexity and procedures. It not only improves the installation efficiency of the photovoltaic bracket, but also the column base is replaceable, which can ensure the reliability of the photovoltaic bracket installation and avoid the situation of component damage caused by on-site welding.

[0004] However, most of the existing photovoltaic brackets are fixed on flat roofs. When there are concavities and convexities on the roof, the fixed position will change, causing the photovoltaic bracket to tilt, affecting the installation, and resulting in poor installation applicability of the photovoltaic bracket. Therefore, it does not meet the existing requirements. For this reason, we propose an adjustable photovoltaic bracket for special-shaped roofs. Content of the Utility Model

[0005] The purpose of the utility model is to provide an adjustable photovoltaic bracket for special-shaped roofs to solve the problem that most of the existing photovoltaic brackets are fixed on flat roofs. When there are concavities and convexities on the roof, the fixed position will change, causing the photovoltaic bracket to tilt, affecting the installation, and resulting in poor installation applicability of the photovoltaic bracket as mentioned in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an adjustable photovoltaic bracket for special-shaped roofs, including: a mounting frame, a fixed cross frame is arranged at the upper end of the mounting frame, a connecting ear seat is arranged at the lower end of the mounting frame, and the connecting ear seat is welded and fixed to the mounting frame;

[0007] It further includes:

[0008] Adjusting frame, which is arranged at the lower end of the connecting ear seat. A positioning frame is arranged outside the lower end of the adjusting frame. A rotating round head is arranged at the upper end of the adjusting frame, and the rotating round head and the adjusting frame are of an integral structure. One end of the connecting ear seat is provided with a fastener, and one end of the fastener passes through the rotating round head and is fixed by an external nut of the connecting ear seat;

[0009] Moving chute, which is arranged inside the positioning frame. The upper end of the moving chute is in an open form, and the adjusting frame moves up and down along the moving chute;

[0010] Arc-shaped base, which is arranged on the lower surface of the positioning frame, and the arc-shaped base and the positioning frame are of an integral structure.

[0011] Preferably, an adjusting groove is arranged inside the adjusting frame, and the adjusting groove penetrates through the adjusting frame. A fixing knob is arranged at the front end of the positioning frame, and one end of the fixing knob passes through the positioning frame and is fixed by an external nut of the adjusting groove.

[0012] Preferably, an installation empty groove is arranged on the front surface of one end of the positioning frame close to the arc-shaped base, and the front end of the installation empty groove is in an open form.

[0013] Preferably, a grounding bolt is arranged inside the installation empty groove, and one end of the grounding bolt penetrates through the arc-shaped base.

[0014] Preferably, a through hole is arranged inside the rotating round head, and the through hole penetrates through the rotating round head.

[0015] Preferably, connecting grooves are arranged on the upper surfaces of the installation frame and the fixed cross frame, and the connecting grooves are in a three-sided open form. Connecting holes are arranged on the inner bottom surface of the connecting grooves.

[0016] Preferably, a rotating groove is arranged inside the lower surface of the connecting ear seat, and after the rotating round head is inserted into the rotating groove, it rotates along the rotating groove.

[0017] Compared with the prior art, the beneficial effects of the present utility model are:

[0018] 1. The utility model adjusts the angle between the positioning frame and the mounting frame by setting an arc-shaped base at the lower end of the positioning frame. The rotating round head is inserted into the rotating groove and rotates along the rotating groove through the fastener, so as to adjust the angle. Moreover, the adjusting frame moves up and down along the moving sliding groove to adjust the length, and is tightened and fixed by relying on the fixing knob. Through the adjustment of the length and angle, it is ensured that the inclined surface of the mounting frame remains unchanged, and the positioning frame is also applicable to roofs of different shapes, thus improving flexibility. Since the arc-shaped base at the lower end of the positioning frame is arc-shaped, the contact area between the arc-shaped lower surface and the roof is small, presenting a circular shape, and the grounding area is small, so it is convenient to be in inclined contact with the roof. Compared with the existing square bottom plate, it can be more closely fixed to the special-shaped roof, thus improving the connection stability, and solving the problem that most of the existing photovoltaic brackets are fixed on the flat roof. When there are bumps and depressions on the roof, the fixed position will change, causing the photovoltaic bracket to tilt, affecting the installation, and resulting in poor applicability of the photovoltaic bracket installation.

[0019] 2. By setting an installation empty groove on the front surface at the lower end of the positioning frame, when fixing the positioning frame, one end of the grounding bolt penetrates through the arc-shaped base and is fixed to the roof, thus realizing the fixation of the entire photovoltaic bracket. The grounding bolt is located inside the installation empty groove, playing a role of protection and shielding. After installation, a sealing cover (not shown in the figure) is covered to seal the installation empty groove, avoiding rain erosion and improving the service life.

[0031] Through length and angle adjustment, it is ensured that the inclined surface of the mounting frame 1 remains unchanged, and the positioning frame 5 is also applicable to roofs of different shapes, thereby improving flexibility. Since the cambered surface base 11 at the lower end of the positioning frame 5 is arc-shaped, the contact area between the arc-shaped lower surface and the roof is small, presenting a circular shape, and the grounding area is small, so it is convenient to be in an inclined contact with the roof.
