Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and particularly relates to a photovoltaic bracket supported by three legs. Background Art

[0002] Affected by the market fluctuations and shortages in the supply of fossil fuels, and the increasing emphasis on ecological environment protection by people, the use of solar photovoltaic power generation has been increasing. As a supporting photovoltaic bracket, it is erected by using columns, beams, purlins and fasteners. The outer frame of the photovoltaic module is connected by purlins and aluminum alloy pressing blocks and installed on the bracket at a certain inclination for sunlight. As listed in the three structural systems in Section 5.2 Structural System of the NB / T10115-2018 Energy Industry Standard "Design Specification for Photovoltaic Bracket Structures" implemented on May 1, 2019 by the National Energy Administration, namely double-row single-slope, single-row single-slope and independent column brackets, they are all frame combined brackets made of metal profiles. Especially for large-area distributed photovoltaic power stations, flat foundations are used to build columns and beams, and purlins are laid in parallel, and then photovoltaic modules are installed with pressing blocks or bolts.

[0003] Insufficiencies of the prior art: The installation forms of existing metal brackets are single, and on-site assembly is cumbersome. It is necessary to adjust the flatness of the foundation and increase cement piers. Theoretically, there will inevitably be a virtual column foot in the four-column installation form, resulting in the instability of the bracket. While the single-column installation form requires a more stable and heavier base to support, and these brackets are difficult to meet the simple installation requirements for both flat ground and mountain forests. Summary of the Invention

[0004] The purpose of the utility model is to overcome the deficiencies in the prior art. According to the axiom in plane geometry that three non-collinear points determine a plane, a photovoltaic bracket is provided that can ignore the horizontal condition of the foundation and uses three column feet as three footholds for support.

[0005] The purpose of the utility model is achieved through the following technical solutions:

[0006] A photovoltaic bracket supported by three legs includes a component installation rod, a support block, a rotating arm, a connecting plate, and a replaceable threaded column. The component installation rods are symmetrically arranged in a group, and the rod body is provided with component installation holes. One end of the support block is connected to the component installation rod, and the other end is connected to the rotating arm. The rotating arms are symmetrically arranged in a group, and each rotating arm is provided with connecting holes at both ends. The two ends of the connecting plate are provided with connecting holes and are connected to the other ends of the two rotating arms. The replaceable threaded column is arranged on the two component installation rods and the connecting plate.

[0007] Preferably, the replaceable threaded column includes a column sleeve and a threaded column foot. The column sleeve is fixedly connected to the bottom of the component installation rod and the middle of the connecting plate, and the threaded column foot is threadedly connected in the column sleeve.

[0008] Preferably, the photovoltaic support is made of metal profiles, including one of stainless steel, carbon steel and aluminum alloy, or a combination thereof.

[0009] Compared with the prior art, the utility model enriches the installation forms of photovoltaic modules. Without the need for column beams and purlins, by rotating two rotating arms to adapt to the installation widths of different specifications of photovoltaic modules, and relying on the replaceable threaded columns to form a three-legged support, the column feet can not only be adjusted in height by lifting, but also the column foot structure form can be replaced to adapt to different application environments and foundation conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0010] Figure 1 is a schematic structural view of the utility model.

[0011] Figure 2 is a schematic structural view of different column foot forms of the utility model.

[0012] In the figure, 1 is a component installation rod; 2 is a support block; 3 is a rotating arm; 4 is a connecting plate; 5 is a replaceable threaded column. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0013] The following are specific embodiments of the utility model in combination with the drawings to further describe the technical solutions of the utility model, but the utility model is not limited to these embodiments.

[0014] As Figures 1 to 2 shown, a photovoltaic support with a three-legged support includes a component installation rod 1, a support block 2, a rotating arm 3, a connecting plate 4, and a replaceable threaded column 5. The component installation rods 1 are symmetrically arranged in a group, and the rod body is provided with component installation holes. One end of the support block 2 is connected to the component installation rod 1, and the other end is connected to the rotating arm 3. The rotating arms 3 are symmetrically arranged in a group, and each rotating arm 3 is provided with connection holes at both ends. The two ends of the connecting plate 4 are provided with connection holes and are connected to the other ends of the two rotating arms 3. The replaceable threaded column 5 is arranged on the two component installation rods 1 and the connecting plate 5.

[0015] The number of component installation rods 1 is 2. The component installation holes on the rod body are connected to the reserved holes on the back of the outer frame of the photovoltaic module through bolts. A support block 2 is provided at the middle and upper part of the rod body and is connected by bolts or welding, and the bottom is connected to the replaceable threaded column 5.

[0016] The number of rotating arms 3 is 2. The connection holes at both ends of each rotating arm 3 are respectively connected to the support block 2 and the connecting plate 4, and are in a relatively rotatable connection state during the installation process until the final installation of the externally provided photovoltaic module is determined and uniformly tightened to form a fixed state.

[0017] The replaceable threaded column 5 includes a column sleeve and a threaded column foot. Three sets are adopted in the embodiment. The column sleeve is connected to the component mounting rod 1 and the connecting plate 4 by welding or bolt fixing. The threaded column foot is threadedly connected in the column sleeve and used as a support after height adjustment, or can be rotated and removed and replaced with another threaded column foot for installation.

[0018] As Figure 2 shown, the ring-shaped column foot is replaced with a tapered pointed column foot to adapt to the installation of the photovoltaic module support in soft soil and gravel in the mountainous area.

[0019] The photovoltaic support selects metal profiles as the manufacturing materials, including one of stainless steel, carbon steel and aluminum alloy, or a combination thereof, so that the support can maintain sufficient installation strength at cost orientation in a suitable environment. In this embodiment, carbon steel profiles with hot-dip galvanized surface treatment are selected. In special cases considering increasing self-weight and corrosion resistance, high-strength concrete can also be selected to cast the photovoltaic support.

[0020] The specific embodiments described herein are merely illustrative of the present invention and are not limited to the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
