Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation equipment technology, and in particular to a photovoltaic inverter mounting bracket device. Background Technology

[0002] With the rapid development of distributed photovoltaic power generation projects, photovoltaic inverters, as core equipment, directly affect system efficiency and safety due to their installation stability, and are widely installed in various scenarios such as industrial and commercial plants and agricultural facilities.

[0003] Existing fixed brackets have several problems: first, the base has poor adaptability, making it difficult to adapt to the fixing needs of different factory roofs (such as concrete and corrugated steel roofs); second, the height and length adjustment precision is insufficient, making it unable to match diverse photovoltaic module layouts; and third, the installation is complex, making it difficult to meet the rapid deployment needs of distributed projects. Therefore, there is an urgent need for a fixed bracket device that is highly adaptable, versatile, and easy to install. Summary of the Invention

[0004] This utility model aims to address the shortcomings of existing technologies by providing a photovoltaic inverter mounting bracket device.

[0018] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0020] like Figures 1-3 As shown, a photovoltaic inverter mounting bracket device includes a base 1, a column 2, a crossbeam 3, a fixing clamp 4, and a transmission mechanism 5.

[0021] The base 1 features multiple arrayed mounting holes 11. The dense arrangement of these holes provides various fixing point options, allowing the base to flexibly adapt to different locations of pre-embedded roof components or on-site drilling, greatly improving installation compatibility and success rate. The bottom of the base 1 is equipped with adjustable anti-slip pads 12. Each pad includes a screw 121 and a rubber pad 122. The screw 121 is threaded to the four corners of the base 1, and the rubber pad 122 is attached to the bottom of the screw 121. By rotating the screws 121 at each corner, the levelness of the base 1 can be precisely adjusted, ensuring the entire support is vertically stable. Simultaneously, the rubber pad 122 effectively increases friction, preventing the support from sliding on smooth roof surfaces and providing cushioning and shock absorption. The base 1 is made of Q355 high-strength steel with a thickness of 8–12 mm, ensuring sufficient load-bearing capacity. The mounting holes 11 have a diameter of 12–16 mm and a spacing of 50–80 mm, allowing connection to different roof foundations via expansion bolts or chemical anchors.

[0022] Two uprights 2 are vertically fixed on both sides of the top of the base 1. Each upright 2 has multiple sets of adjustment holes 21 along its height. The uprights 2 are made of rectangular steel tubing with a cross-sectional dimension of 80mm × 80mm × 5mm. The adjustment holes 21 are spaced 50mm apart along the height of the uprights 2. The height of the crossbeam 3 can be precisely adjusted by passing bolts through different adjustment holes 21, with an adjustment range of 0.5–2m to accommodate different roof heights and photovoltaic module angle requirements.

[0023] The crossbeam 3 is horizontally installed on the front side of the column 2 via a fixing clamp 4. The fixing clamp 4 is made of high-strength metal and includes a U-shaped clamp 41, a connecting plate 42 connected to the upper and lower side plates of the clamp 41, and a fastening bolt 43 threaded to the center of the front side of the clamp 41. The clamp 41 is clamped on the front side of the fixed section 31, and the connecting plate 42 is in close contact with the column 2 and is fixed to the adjustment hole 21 by bolts. The fastening bolt 43 is threaded to the fixed section 31. During installation, the clamp 41 is clamped onto the fixed section 31 of the crossbeam 3, the connecting plate 42 is in close contact and fixed to the adjustment hole 21 of the column 2 by bolts, and then the fastening bolt 43 in front of the clamp 41 is tightened to fix the fixed section 31. The advantage of this connection method is that it achieves "three-point positioning": the clamp 41 holds the crossbeam tightly, the connecting plate 42 is fixed to the column, and the fastening bolt 43 provides an additional fixing point, forming a very stable rigid connection that effectively prevents the crossbeam 3 from shaking or twisting during use.

[0024] The crossbeam 3 includes a fixed section 31 and a telescopic section 32 nested within it. The telescopic section 32 is driven to extend and retract via a transmission mechanism 5 mounted on the fixed section 31. Both the fixed section 31 and the telescopic section 32 are made of aluminum alloy profiles, which are lightweight and corrosion-resistant. The fixed section 31 has a horizontally shaped "U" cross section, and the telescopic section 32 has a horizontally shaped U cross section. The nested design ensures that the telescopic section 32 will not shift vertically or laterally during movement, ensuring the flatness of the top surface of the crossbeam 3 during extension and retraction, and providing a stable mounting surface for the inverter. The transmission mechanism 5 includes several gear teeth 51 fixed to the inner wall of the upper side plate of the telescopic section 32, and a rotating shaft 52 rotatably connected to the center of the front side of another sleeve 41. The rotating shaft 52 passes inside the telescopic section 32 and is fixedly connected to a gear 53 that meshes with the gear teeth 51. A handle 54 is fixedly connected to the outer end of the rotating shaft 52. Turning the handle 54 causes the gear 53 to rotate and mesh with the gear teeth 51, thereby enabling the telescopic section 32 to extend or retract smoothly. The adjustment range is 1 to 2.5m, which can be adapted to inverters of different sizes.

[0025] A locking mechanism is provided between the fixed section 31 and the telescopic section 32. The locking mechanism includes several positioning holes along the length of the bottom of the fixed section 31 and a clamping bolt threaded into the positioning holes. The telescopic section 32 is locked in place by the clamping bolt. The advantages of using gear 53-gear 51 transmission are high adjustment accuracy, labor-saving operation, and smooth and reliable transmission, allowing for easy stepless precise adjustment of the length of the crossbeam 3. After adjustment to the desired length, the telescopic section 32 is locked in place by the locking mechanism (such as the clamping bolt passing through the positioning hole at the bottom of the fixed section 31). The advantages of this locking method are simple structure, high locking force, and effective prevention of the telescopic section from retracting under load.

[0026] The connector on the back of the inverter spans across the fixed section 31 and the telescopic section 32 and is secured with bolts. The back of the inverter typically has a U-shaped or C-shaped mounting bracket. During installation, this bracket is directly straddled on the adjusted length of the crossbeam 3 (covering the fixed section 31 and the telescopic section 32), and then bolts are screwed in from above to firmly press the inverter onto the top surface of the crossbeam 3. The advantages of this installation method are its extreme simplicity and speed, and because the force is evenly distributed along the entire crossbeam 3, the fixation is very reliable.

[0027] Base 1 Machining and Installation: A 400mm×400mm×10mm base 1 is cut from a Q355 steel plate. Nine 14mm diameter mounting holes 11 are machined at 100mm intervals. M12 nuts are welded to the four corners of the base. A 50mm long screw rod 121 is screwed into the nuts. A 50mm×50mm×10mm rubber pad 122 is attached to the bottom of the screw rod 121 to create an anti-slip footpad. During installation, the mounting hole positions are marked on the top of the factory building. After drilling holes in the concrete roof, M12 expansion bolts are inserted. The mounting holes 11 of the base 1 are aligned with the bolts, and the nuts are tightened with a wrench. The level of the base 1 is adjusted by rotating the screw rod 121 to ensure the bubble in the level is centered.

[0028] Fabrication and installation of column 2: Select an 80mm×80mm×5mm rectangular steel pipe and cut it into a 2.5m long column 2. Fabricate two sets of symmetrical 10mm diameter adjustment holes 21 every 50mm along the height direction. Weld 100mm×100mm×10mm flanges to both sides of the top of base 1, and weld matching flanges to the bottom of column 2. Connect and fix column 2 to the flanges of base 1 using four M16 bolts. Use a level to calibrate the verticality of the column, controlling the error within ±1°.

[0029] Crossbeam 3 machining and installation: Fixed section 31 is made of 100mm×50mm×3mm aluminum alloy profile (1m long), with 8mm diameter positioning holes machined every 100mm along its length; telescopic section 32 is made of 80mm×40mm×3mm aluminum alloy profile (1.5m long), with gear teeth 51 machined and nested inside fixed section 31. A transmission mechanism 5 is installed beside crossbeam 3, with gear 53 meshing with gear teeth 51. Fixing clamp 4 secures fixed section 31 by bolts passing through adjustment holes 21; depending on the inverter length (e.g., 1.2m), rotating handle 54 drives gear 53, causing telescopic section 32 to extend 0.2m. The clamping bolts are then passed through the positioning holes to lock telescopic section 32, ensuring crossbeam 3 is level and free from wobbling.

[0030] Then, the connectors on the inverter are straddled on the fixed section 31 and the telescopic section 32 and secured with bolts.

[0031] This utility model's device integrates height adjustment, length adjustment, stable fixing, and rapid installation, making it particularly suitable for photovoltaic inverter installation in complex rooftop environments such as industrial and commercial plants. It effectively solves the problems of poor adaptability, inconvenient adjustment, and insufficient stability of traditional brackets.
