Description

Technical Field

[0001] The utility model relates to the technical field of solar brackets, in particular to a solar photovoltaic bracket. Background Art

[0002] Solar panels absorb sunlight and convert solar radiation into electrical energy directly or indirectly through the photoelectric effect or photochemical effect. With the increasing consumption of various resources, solar energy, as a relatively ideal energy source, has become increasingly mature and widely used. Currently, the most common method is to lay large areas of solar photovoltaic panels in designated areas to convert solar energy. When laying solar photovoltaic panels, brackets are required to set them up at the appropriate angle to maximize the use of solar energy. Existing photovoltaic brackets usually use cement as a base, and several pillars are fixed to the appropriate angle by welding. The photovoltaic panel is then fixed to the front end of the pillars. This method is laborious to fix, and the welding method cannot be disassembled, making it inconvenient to adjust the tilt angle of the photovoltaic panel. Furthermore, if a pillar is damaged, it is difficult to replace it. Utility Model Content

[0027] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0028] Example

[0029] As mentioned in the background technology, a photovoltaic bracket is required for the installation of the solar photovoltaic panel 8. The inventor found in the actual installation and subsequent use process that the existing photovoltaic bracket has many defects. For example, during installation, multiple pillars need to be welded into the required frame, and then the photovoltaic panel 8 is installed. Although the angle of the photovoltaic panel 8 can be kept accurate, this process requires a lot of manpower and time, and the pillars are not easy to disassemble during subsequent use, which causes more difficulties for replacement and maintenance. Therefore, the inventor used existing components to design a new photovoltaic bracket, which is described in detail below with reference to the diagrams.

[0030] This embodiment provides a solar photovoltaic bracket, see Figure 1, including a bottom frame 1, the bottom frame 1 is four fixedly connected plates, and a plurality of support columns 2 are installed on the inner end surface of the bottom frame 1. In this solution, in order to facilitate the adjustment of the height of the overall bracket, and then more conveniently adjust the angle of the photovoltaic panel 8, the support column 2 is designed to be height-adjustable. Specifically, the support column 2 includes a lifting end 21 and a base end 22. The lifting end 21 can slide up and down along the base end 22, and the lifting end 21 has a plurality of threaded holes 23 vertically opened, which are fixed by locking bolts 24 passing through the threaded holes 23, and in order to improve stability, each lifting end 21 is fixed by at least two locking bolts 24, that is, it is fixed by the locking bolts 24 and the threaded holes 23 at different heights to achieve the adjustment of the height of the photovoltaic bracket.

[0031] In this embodiment, two first profiles 3 are installed on the shorter sides of the bottom frame 1. The first profile 3 and the profiles mentioned below include at least two opposite end faces with mounting grooves 12, which can replace the welding connection method in the prior art. Specifically, a right-angled fixing frame 14 is provided at the bottom of the first profile 3. The fixing frame 14 is fixed to the bottom frame 1 and the mounting groove 12 of the first profile 3 by bolts respectively, and in order to improve the stability of the first profile 3, each first profile 3 is connected to the bottom frame 1 by at least three fixing frames 14.

[0032] Secondly, the upper ends of the two first profiles 3 are connected to two second profiles 5 through hinges 4, and the second profiles 5 are arranged upwardly. In this solution, Figure 3 The hinge 4 includes a first hinge end 41 and a second hinge end 42 connected thereto, and the first hinge end 41 and the second hinge end 42 between the first profile 3 and the second profile are both connected with a sliding block 43, and the sliding block 43 is slidably connected to the mounting groove 12 and can be fixed by bolts, and the sliding blocks 43 of the first hinge end 41 and the second hinge end 42 can slide in the mounting groove 12, and then the installation angle of the second profile 5 can be adjusted so that the photovoltaic panel 8 can be tilted to a suitable angle.

[0033] The photovoltaic panel 8 is installed in such a way that two fourth profiles 7 are connected between the two ends of the second profiles 5, and the second profiles 5 and the fourth profiles 7 are installed with multiple photovoltaic panels 8 through connectors, and in order to improve the installation strength between the two adjacent photovoltaic panels 8, a fifth profile 9 is connected between the middle positions of the two fourth profiles 7, combined with Figure 2, and the two adjacent photovoltaic panels 8 are connected to the fifth profile 9 through a connecting piece. The design of the fifth profile 9 is consistent with that of the second profile 5. It can be regarded as moving the second profile 5 to the middle position of the two fourth profiles 7. Through the design of the second profile 5, the fourth profile 7 and the fifth profile 9, the photovoltaic panel 8 can be installed at an angle, and the inclination angle is adjusted by the hinge 4 between the first profile 3 and the second profile 5.

[0034] On the basis of the above structure, the inclined upper end of the second profile 5 needs to be supported, and the end of the second profile 5 away from the first profile 3 is hinged to the third profile 6 through the hinge 4. The third profile 6 is arranged vertically and the bottom end is connected to the first profile 3. The hinge 4 between the second profile 5 and the third profile 6 is different from the hinge 4 between the first profile 3 and the second profile 5. Figure 4 However, the first hinged end 41 is designed in the same way and is also connected to a sliding block 43, which slides with the mounting groove 12 of the second profile 5 and is fixed by bolts. The second hinged end 42 between the two is connected to the upper end of the third profile 6. Therefore, the second hinged end 42 does not need to be connected to the sliding block 43, and can be directly fixed to the upper end of the third profile 6 by bolts. The bottom end of the third profile 6 is connected to the first profile 3 through a right-angle frame, and the right-angle frame is fixed to the mounting grooves 12 of the two by bolts.

[0035] Moreover, a sixth profile 10 is connected between the middle positions of the two longer sides of the bottom frame 1. Figure 2 The dotted line is used to describe it, which is consistent with the setting height and extension direction of the first profile 3. It can be regarded as the case of moving the first profile 3 horizontally to the middle position of the bottom frame 1, but the length of the sixth profile 10 is consistent with the distance between the inner end faces of the two longer sides of the bottom frame 1, and the two ends are installed with the bottom frame 1 through the fixing frame 14, and the upper end of the sixth profile 10 is connected with the inclined seventh profile 11, and the seventh profile 11 is arranged vertically to the sixth profile 10, and the top of the seventh profile 11 is hinged to the fifth profile 9 through the hinge 4, and the hinge 4 between the seventh profile 11 and the fifth profile 9 and the hinge 4 between the second profile 5 and the third profile 6 are consistent in design. It can be seen in the figure that no unnecessary details are given. The bottom end of the seventh profile 9 is connected to the sixth profile 10 through a bracket, and the bracket is fixed to the mounting groove 12 of the two by bolts, but the inclined seventh profile 11 can support the sixth profile 10, thereby forming a support for the middle position of the two adjacent photovoltaic panels 8, further improving the stability of the installation of the photovoltaic panel 8.

[0036] In this embodiment, combined with Figure 5The connecting parts between the photovoltaic panel 8 and the second profile 5 and the fifth profile 9 are also designed. Specifically, the connecting parts include a mounting frame 13. The mounting frame 13 includes a U-shaped plate, and the upper end of the U-shaped plate is provided with two connecting ear plates, which are fixed to the photovoltaic panel 8 through the ear plates. The bottom end of the U-shaped plate is fixed to the mounting groove 12 by bolts, and at least two sets of mounting frames 13 are arranged between each profile and a single photovoltaic panel 8. This can ensure the installation strength of the photovoltaic panel 8. Secondly, since the mounting grooves 12 are opened on the profiles, the profiles can adapt to the installation of photovoltaic panels 8 of different sizes, thereby improving the performance.
