Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of photovoltaic brackets, in particular to a novel adjustment mechanism for photovoltaic brackets. Background Art
[0002] Currently, the most widely used distributed photovoltaic power generation systems are those built on the rooftops of urban buildings. These projects must be connected to the public grid, a standard for green buildings. This not only reduces pressure on the public grid but also lowers electricity costs for users. Typically, in the construction of such large-scale photovoltaic power generation projects, the construction and installation costs of photovoltaic mounts account for approximately 21% of the total project investment. Photovoltaic mounts are the primary components of solar power generation, used to adjust the angle of the photovoltaic modules. PV modules convert absorbed sunlight into electrical energy, so the intensity of sunlight directly affects the amount of power generated. Photovoltaic mount structures are generally categorized as fixed-angle and tracking. Compared to tracking mounts, fixed-angle mounts offer greater stability, easier installation, and lower cost. As tracking mount technology has not yet reached a high level, domestic substation construction projects currently utilize fixed, adjustable-angle mounts.
[0003] To achieve maximum power generation efficiency, existing photovoltaic tracking and adjustable supports require adjustment. One such mechanism, a hand-cranked jack, offers low cost and simple adjustment. However, under heavy loads, the mechanism can experience torsional instability, leading to failure and even damage to the support. Utility Model Content
[0004] In response to the above-mentioned technical problems to be solved, a novel adjustment mechanism for a photovoltaic support is provided, which adds a lateral stability structure to strengthen the disadvantage of the photovoltaic support being prone to torsional instability.
[0005] To achieve the above-mentioned purpose, the utility model discloses a novel adjustment mechanism for a photovoltaic bracket, comprising an outer frame and a transmission screw rod that passes through the outer frame in a horizontal direction. The outer frame is composed of two first supports and two second supports that are staggered and connected to each other. The outer frame is diamond-shaped, and a screw nut coaxially installed with the transmission screw rod is provided at the horizontal connection between the first support and the second support. A vertically arranged sleeve assembly is installed in the outer frame, and the transmission screw rod passes through the sleeve assembly.
[0006] Furthermore, the first support and the second support are both square tube structures, the width of the first support is greater than the width of the second support, the end of the second support is placed inside the first support, and a bolt is provided at the connection between the first support and the second support on the axis of the transmission screw.
[0007] Furthermore, the bolts pass through the first support and the second support and are connected to the screw nuts, and each set of screw nuts is connected to two bolts on the outside of the transmission screw.
[0008] Furthermore, the sleeve assembly includes an outer tube and an inner tube, the inner tube is inserted into the outer tube, and the transmission screw passes through the reserved grooves of the inner tube and the outer tube.
[0009] Furthermore, the length of the reserved groove of the outer tube is greater than the length of the reserved groove of the inner tube.
[0010] Furthermore, the connection between the first support and the second support of the outer frame in the vertical direction is connected by a pin shaft, and the first support, the second support and the outer tube are fixed by the pin shaft at one corner position, and the first support, the second support and the inner tube are fixed by the pin shaft at another corner position.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. Using square tube as the external frame has higher torsion resistance;
[0013] 2. Use inner and outer tubes to enhance the overall anti-torsion ability, making the overall structure more stable and able to withstand greater loads;
[0014] 3. When the installation hole position needs to be parallel to the frame plane, the inner and outer tube hole positions can be adjusted directly without adding adapters. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0021] An embodiment of the present utility model, as Figure 1 As shown, the outer frame is formed by two first supports 1 and two second supports 2 connected in an interlaced manner. The outer frame is rhombus-shaped. A screw nut 7 coaxially installed with the transmission screw 3 is provided at the horizontal connection between the first support 1 and the second support 2. A vertically arranged sleeve assembly is installed in the outer frame. The transmission screw 3 passes through the sleeve assembly, which increases the lateral stability structure and strengthens the disadvantage of the rhombus-shaped outer frame that is prone to torsional instability.
[0022] The first support 1 and the second support 2 are both square tube structures. The width of the first support 1 is greater than that of the second support 2. The end of the second support 2 is placed inside the first support 1. A bolt 6 is provided at the connection between the first support 1 and the second support 2 on the axis of the transmission screw 3.
[0023] like Figure 3 As shown, the bolts 6 pass through the first support 1 and the second support 2 and are connected to the screw nuts 7. Each set of screw nuts 7 is connected to two bolts 6 on the outside of the transmission screw 3, converting the rotational movement of the transmission screw into a linear movement of the screw nut, and at the same time driving the first support and the second support to complete the opening and closing, thereby realizing the adjustment of the photovoltaic bracket.
[0024] like Figure 2 As shown, the sleeve assembly includes an outer tube 8 and an inner tube 4. The inner tube 4 is inserted into the outer tube 8. The transmission screw 3 passes through the reserved slots 9 of the inner tube 4 and the outer tube 8. The reserved slot 9 of the outer tube 8 is longer than the reserved slot 9 of the inner tube 4. Rotating the transmission screw drives the first and second supports to open and close, and the inner and outer tubes to expand and contract, thereby adjusting the distance between the mounting holes. Due to the coordination of the inner and outer tubes, when the entire structure is subjected to a large load and a tendency to twist around the transmission screw, this tendency is offset by the inner and outer tubes, and only moves along the axial direction of the inner and outer tubes, making the overall structure more stable and able to withstand greater loads.
[0025] The connection between the first support 1 and the second support 2 of the outer frame in the vertical direction is connected by a pin 5. The pin 5 is used at one corner to fix the first support 1, the second support 2 and the outer tube 8, and the pin 5 is used at another corner to fix the first support 1, the second support 2 and the inner tube 4.
[0026] The working principle of this embodiment is as follows: the first support and the second support are a large and a small square tube, the second support can be placed inside the first support, the two first supports and the second support are combined into a diamond-shaped frame, two screw nuts are installed at a diagonal position of the outer frame, the transmission screw passes through the screw nut, a pin is used at one corner position to fix the first support, the second support and the outer tube, a pin is used at one corner position to fix the first support, the second support and the inner tube, the inner tube is inserted into the outer tube, the transmission screw passes through the reserved grooves of the inner tube and the outer tube, and the screw is rotated at this time to drive the first support and the second support to open and close, the inner tube and the outer tube to expand and contract, and the distance between the mounting holes is adjusted. Due to the cooperation between the inner tube and the outer tube, when the whole is subjected to a large load and a torsional tendency around the transmission screw occurs, it can be offset by the inner tube and the outer tube, and only moves along the axial direction of the inner and outer tubes, making the overall structure more stable and able to withstand a larger load.
