Description

Technical Field

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

[0002] Solar energy is a renewable energy source. For oil fields that are often constructed outdoors, the effective use of this new energy source can be more energy-saving, environmentally friendly, economical and convenient. Photovoltaic brackets are key components of photovoltaic power generation systems and are mainly used to fix and support solar photovoltaic panels.

[0003] Traditional photovoltaic racks often use fixed installation methods, such as ground trusses. This type of rack installation typically involves first securing the base using a prefabricated cement foundation, then supporting the truss with at least two columns fixed to the base. The photovoltaic panels are then fixed to the trusses. This structure requires at least two sets of bases and columns to secure the trusses during installation, which is not only complex but also reduces consumable materials. Furthermore, in areas with complex terrain and steep slopes, the horizontal span of the base and the vertical height of the columns increase as the ground flatness and elevation increase. This significantly increases the rack's footprint, impacting the overall land utilization rate.

[0004] The utility model patent document with authorization announcement number CN205847168U and authorization announcement date 2016 / 12 / 28 discloses an adjustable photovoltaic fixed support structure, which includes a photovoltaic panel positioning frame, a lower support column and an upper support column. The lower end of the lower support column is provided with a base connected to the ground, the lower end of the upper support column is inserted into the lower support column, and the upper end of the upper support column is provided with a swingable connecting seat. The connecting seat is connected to the photovoltaic panel positioning frame through a rotating shaft. One end of the positioning frame is provided with a support arm, and the other end is provided with an auxiliary support arm. The support arm is provided with a fixed connecting sleeve and an adjustment arm. One end of the adjusting arm inserted into the connecting sleeve is connected to the connecting sleeve by a thread. When the adjusting arm is rotated, the thread drives the adjusting arm to reciprocate inside the connecting sleeve along the extension line of its center, thereby changing the length of the main support rod. The other end of the adjusting arm is provided with a swingable joint. The upper support column is provided with a fixedly connected clamp. The swing joint is hinged on the clamp. The main support rod with adjustable length combined with the swingable joint can achieve the purpose of adjusting the angle of the photovoltaic panel.

[0005] Compared to traditional ground-mounted truss photovoltaic supports, this structure features a single, single ground-mounted base and support column, saving floor space and improving the high material consumption of the support. However, for outdoor locations, which are often relatively open and have complex environmental conditions, this structure requires fewer support arms for the photovoltaic panel positioning frame. The adjustment arm and the clamp are connected via an articulated seat, resulting in a relatively concentrated local support force and lower support strength. Furthermore, during construction, the support arms of the photovoltaic panel positioning frame are installed through the connection holes at the ends of the clamp. The support arms, clamp, and upper support column all need to be installed and fixed simultaneously. This reduces the safety factor for taller photovoltaic supports and affects construction efficiency. Utility Model Content

[0008] Furthermore, connecting fins are fixedly provided on the outer wall surface of each hoop piece, the connecting fins are provided with fin connecting holes and auxiliary diagonal braces are connected through the fin connecting holes, and the upper ends of the auxiliary diagonal braces are detachably connected to the photovoltaic panel connecting frame.

[0009] Furthermore, the connecting fins are obliquely arranged on the corresponding hoop pieces to adapt to the angle of the connecting end of the corresponding auxiliary diagonal brace.

[0010] Furthermore, vertical legs are provided between the photovoltaic panel connection frame and the top end of the support column.

[0011] Furthermore, the vertical legs are located in the middle of the photovoltaic panel connection frame and a supporting base plate is provided at the lower end.

This modular design is easy to install, thereby improving construction efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0024] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0025] The photovoltaic bracket of this utility model can achieve the purpose of improving the inconvenience of bracket installation and low construction efficiency. The photovoltaic bracket of this utility model adopts a modular design, so that the clamps, diagonal braces, and photovoltaic panel connection frame can be installed in steps, which solves the problem of existing brackets requiring simultaneous installation, facilitates installation, and improves construction efficiency.

[0026] As a basic solution, the photovoltaic support of the present invention includes a support column 16 and a photovoltaic panel connection frame, such as Figure 1-3 As shown, the support base column 16 fixed on the ground can be made of, for example, reinforced concrete columns, which are high in strength and economical. As the basic support of the entire photovoltaic bracket, the stability of the bracket can be ensured. The photovoltaic panel connection frame is used to install and support the photovoltaic panel 17. A support clamp 7 is provided at the upper end of the support base column 16. The installation of the clamp 7 is convenient and simple. It can be completed by a fastener that can tighten the clamp 7. In addition, the clamp 7 has a good load-bearing capacity. The clamp 7 includes at least two mutually connected clamp pieces 8. The end of each clamp piece 8 is provided with a clamp for tightening with the corresponding The connecting ear plate 9 connected to the adjacent hoop pieces 8 can complete the locking, fixing and disassembly of the two hoop pieces 8 through the connecting ear plate 9, which is convenient for maintenance or replacement of the bracket. At least one of the two interconnected connecting ear plates 9 has an extension section, and the extension section is provided with a diagonal support connection hole 11, and the diagonal support connection hole 11 is used to connect the detachable main diagonal support rod 4. Extending at least one connecting ear plate 9 can expand the connection area for connecting the main diagonal support rod 4, avoiding using the same connection hole as the connecting ear plate 9. The upper end of the main diagonal support rod 4 is detachably connected to the photovoltaic panel connecting frame.

[0027] As a preferred embodiment, the outer wall surface of each hoop piece 8 of the hoop 7 is fixedly provided with a connecting fin 10, such as Figure 3 As shown, the connecting fin 10 is provided with a fin connecting hole 12, and an auxiliary diagonal support rod 5 is connected through the fin connecting hole 12. Adding the auxiliary diagonal support rod 5 can disperse the supporting force of the photovoltaic panel connecting frame concentrated at the connection portion between the main diagonal support rod 4 and the connecting ear plate 9, thereby enhancing the strength of the bracket. The upper end of the auxiliary diagonal support rod 5 is detachably connected to the photovoltaic panel connecting frame to facilitate subsequent disassembly and maintenance. In other embodiments, it can also be set as a connecting column, and the connecting column can also be connected to the auxiliary support rod to share the supporting force and improve the strength.

[0028] As a preferred embodiment, the connecting fin 10 can be tilted and arranged on the corresponding hoop piece 8 to facilitate adaptation to different angles of the connection end of the corresponding auxiliary diagonal brace 5. In other embodiments, the connecting fin 10 can also be perpendicular to the tangent of the hoop piece 8 at the connection position, but this method is limited to the auxiliary diagonal brace 5 connected to the photovoltaic panel connection frame being able to be vertically connected to the connecting fin 10.

[0029] As a preferred embodiment, a vertical support leg 6 is further provided between the photovoltaic panel connection frame and the top of the support base column 16. The vertical support leg 6 is located in the middle of the photovoltaic panel connection frame and a support base plate is provided at the lower end. The vertical support leg 6 can not only increase the longitudinal stability of the bracket, but also serve as a support and load-bearing part for the photovoltaic panel connection frame, making it more convenient and labor-saving for workers during the installation process. In other embodiments, the vertical support leg 6 may not be provided, but this embodiment requires manpower to lift the frame or use tools to lift the frame when installing the photovoltaic panel connection frame, which is relatively labor-intensive and complicated.

[0030] As a preferred embodiment, the extension section and the diagonal brace connecting hole 11 only need to be provided on any one of the two connecting ear plates 9 connecting the two hoops 8 to facilitate the connection of the main diagonal brace rod 4. In other embodiments, both connecting ear plates 9 are provided with extension sections, and the main diagonal brace rod 4 can be put on the ear plates and connected by means of fastening such as bolts 15. However, this embodiment requires a groove to be provided at the end where the diagonal brace rod is connected to it, which increases the difficulty of construction and affects efficiency.

[0031] As a preferred embodiment, the diagonal support connection hole 11 and the fin connection hole 12 are waist-shaped holes, which can increase the tolerance of the installation position and reduce the difficulty of installation. In addition, the waist-shaped hole structure has a smooth transition, which can evenly distribute the stress of the connecting ear plate 9 and improve the strength of the connecting ear plate 9. In other embodiments, it can also be a circular hole. Although the tolerance for installation is not as high as that of the waist-shaped hole, it can also achieve the purpose of evenly distributing the stress of the connecting ear plate 9.

[0032] As a preferred embodiment, the photovoltaic panel connection frame includes a crossbeam 2 and a longitudinal beam 3, and the crossbeam 2 and the corresponding longitudinal beam 3 are connected at the intersection by a corner piece 14, such as Figure 4-5 As shown, the connection method of the corner piece 14 can enhance the strength of the connection position, thereby enhancing the stability of the entire photovoltaic panel connection frame and extending the service life. In addition, during the construction process, the connection and fixation can be completed by, for example, bolts 15 or other fastening methods, which is convenient for installation and increases construction efficiency.

[0033] As a preferred embodiment, the upper ends of the main diagonal struts 4 and the auxiliary diagonal struts 5 are connected to the corresponding longitudinal beams 3. Adjustment holes 13 are arranged along the length direction of the longitudinal beams 3, and each diagonal strut can be adjusted to be connected to different positions. This has a high tolerance for the requirements of the prepared diagonal strut length and the installation connection position, and plays a fool-proof role during installation. In other embodiments, a connection hole can be set, but this requires strict unification of the length of the diagonal struts to avoid the inability to connect to the longitudinal beam 3 when the diagonal struts are not long enough.

[0034] As a preferred embodiment, the cross beam 2 and the longitudinal beam 3 are both channel steel beams. Channel steel is used as the main material of the photovoltaic panel connection frame. It has the advantages of high strength and good corrosion resistance and can adapt to the complex environment in the field. Moreover, the hollow structure of the channel steel makes it light in weight, which is convenient for transportation and installation during construction. In other embodiments, 4040 aluminum profiles can also be used to make the photovoltaic panel connection frame. This profile does not require drilling and can be fastened by nuts and bolts 15. At the same time, it is light in weight and easy to install.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. The scope of patent protection of the present invention shall be based on the claims. Any equivalent structural changes made using the description and drawings of the present invention shall also be included in the scope of protection of the present invention.
