Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to a vertical photovoltaic support for fishery-solar complementary use. Background Technology

[0002] Solar-aquaculture integration is a green energy model that combines aquaculture with photovoltaic power generation. By installing photovoltaic panels on the surface of fishponds, it achieves the dual benefits of "power generation on the water and fish farming underwater," effectively improving land and solar energy utilization. Currently, the core technical challenge in this field lies in designing a photovoltaic support structure adapted to the aquatic environment. This structure must allow for angle adjustments to the photovoltaic panels to maximize light absorption while ensuring the stability of the support structure in the aquatic environment and reducing manual maintenance costs.

[0003] In the prior art, such as Chinese utility model patent publication number CN221748265U, a vertical photovoltaic panel support is disclosed, which achieves assembly and disassembly through a movable connection between the support frame and the solar panel, and uses a movable connection between a fixed column and a second fixed plate to achieve angle adjustment. While this solution solves the problem of assembling and disassembling photovoltaic panels, it has the following drawbacks:

[0004] 1. The movable connection structure between the support frame and the fixed plate is prone to swaying under the action of wind on the water surface, especially in high humidity and windy environments such as aquaculture waters, which may cause the photovoltaic panel to shift at the angle or be damaged.

[0005] 2. Angle adjustment requires manual operation of each installation frame. In large-scale fishery-solar hybrid projects, the water surface operation is difficult, time-consuming and labor-intensive, and batch synchronous adjustment cannot be achieved.

[0006] 3. The lack of automated drive components makes it impossible to remotely control the light source in real time according to the angle of illumination, thus limiting the utilization rate of light energy. Utility Model Content

[0007] The technical problem to be solved by this utility model is to provide a vertical photovoltaic bracket for fishery-solar complementary systems, which uses a drive component to achieve synchronous drive of the rotating shaft and the connecting shaft, thus solving the efficiency problem of manual adjustment in the prior art; the bracket's stability is enhanced by using support blocks, support blocks and isolation protective pads to overcome the influence of wind; at the same time, the design of countersunk holes and connecting bolts ensures a reliable connection between the mounting frame and the connecting shaft, thus breaking through the bottleneck of the prior art in terms of structural design and drive logic.

[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0009] A vertical photovoltaic support frame for fishery-solar hybrid applications includes a mounting base plate, support columns, connecting shafts, a mounting frame, and a drive assembly. The mounting base plate is laid on a designated water surface. Support columns are equidistantly arranged on the mounting base plate, with the lower end face of each support column perpendicularly connected to the upper end face of the mounting base plate, and the upper end face of each support column perpendicularly connected to the lower end face of a mounting box. The support columns are connected to the mounting frame via connecting shafts, and photovoltaic panel assemblies are snapped into place inside the mounting frame. A rotating shaft is installed inside each support column, and a drive assembly is installed inside the mounting box. The drive assembly is connected to the rotating shaft via a transmission connection, and both sides of the mounting frame are connected to the rotating shaft via connecting shafts.

[0010] In the preferred embodiment, the bottom surface of the support column is fixedly connected to the mounting base, and the mounting base and the mounting plate are respectively provided with threaded holes and are fixedly connected by mounting bolts. The upper end surface of the mounting base and the side wall of the support column are connected to the support block.

[0011] In a preferred embodiment, a rotating shaft is arranged parallel inside the support column, and multiple connecting shafts are arranged equidistantly from top to bottom inside the support column. A driving bevel gear is fixedly installed on the outer wall of the rotating shaft, and a driven bevel gear is correspondingly installed at the end of the connecting shaft and meshes with the driving bevel gear. The rotation of the rotating shaft drives the driven bevel gear and the connecting shaft to rotate synchronously.

[0012] In a preferred embodiment, a slot is provided on the inner wall of the mounting frame, and a countersunk hole is provided in the slot. The slot is inserted into the photovoltaic panel assembly. The connecting bolt passes through the countersunk hole in the slot and is threaded into the connecting shaft to achieve a fixed connection between the mounting frame and the connecting shaft. The height of the photovoltaic panel assembly is greater than the height of the mounting frame to facilitate external disassembly and assembly.

[0013] In the preferred embodiment, an isolation protective pad is adhered inside the mounting frame slot, and the photovoltaic panel module is snapped into the inner side of the isolation protective pad to isolate friction and increase friction, thereby preventing the photovoltaic panel module from shaking.

[0014] In a preferred embodiment, the drive assembly includes a worm, a drive motor, and a worm wheel; the worm is arranged parallel to each other inside the fixed housing, and one end of the worm is fixedly connected to the output shaft of the drive motor; the upper end of the rotating shaft passes through the lower end face of the fixed housing, and the worm wheel fixed at the top of the rotating shaft meshes with the worm.

[0015] In a preferred embodiment, a support block is fixed inside the support column, and a bearing is installed inside the support block. The rotating shaft is rotatably connected to the support block through the bearing to stabilize the rotation of the rotating shaft.

[0016] A vertical photovoltaic support structure for fishery-solar hybridization has the following beneficial effects during use:

[0017] 1. The drive motor in the drive assembly drives a worm gear transmission, which synchronously drives the rotating shaft and the drive bevel gear, enabling batch angle adjustment of multiple connecting shafts and mounting frames. Compared to the manual adjustment method in existing technologies, this allows for remote control of photovoltaic panels to track the sunlight angle in real time, significantly improving solar energy utilization. The meshing transmission between the worm gear and the worm has a self-locking characteristic, locking the position of the rotating shaft when stationary, preventing the photovoltaic panels from shifting angle under wind force, and ensuring stable power generation.

[0018] 2. The bottom of the support column is fixed to the mounting base plate by the mounting seat, and the support block reinforces the side wall of the support column, which can resist the lateral wind force in the water environment; the support block inside the support column supports the rotating shaft by bearing, which avoids the shaking when the long shaft rotates, ensures the stable meshing of the bevel gear, and solves the problem of transmission failure caused by shaft shaking in the existing technology.

[0019] 3. The countersunk holes on the inner wall of the mounting frame cooperate with the connecting bolts to rigidly fix the mounting frame and the connecting shaft, avoiding the risk of loosening caused by the movable connection in the existing technology; the height of the photovoltaic panel module is greater than that of the mounting frame, and the exposed part is convenient for disassembly and replacement during water surface operations. With the help of the isolation and protective pad, friction and wear are reduced, the efficiency of photovoltaic panel replacement is improved, and maintenance costs are reduced.

[0020] 4. The mounting base can be laid directly in the aquaculture water area without additional land occupation. At the same time, the photovoltaic panels provide a shading environment for underwater aquaculture, achieving the dual benefits of "power generation + aquaculture". The fully sealed design of the drive components can withstand the high humidity environment on the water surface, extend the service life of the equipment, reduce the frequency of underwater equipment replacement, and reduce the interference with the aquaculture ecosystem.

The mounting base plate 1 is made of high-density polyethylene and features a floating structure. It is anchored underwater on the surface of a designated aquaculture area. Support columns 2 are evenly spaced at 2m intervals on its top surface. The support columns 2 are made of stainless steel tubing, with their lower ends welded perpendicularly to the upper end of the mounting base plate 1. Their upper ends are bolted to the lower end of the mounting box 7. The mounting frame 4 is hinged to the support columns 2 via connecting shafts 3 with bearings at both ends. A stepped slot is provided inside the mounting frame 4, and photovoltaic panels 5 are secured in this slot using elastic clips. A rotating shaft 8 is housed within the hollow cavity of each support column 2. The drive assembly 10 is sealed inside the mounting box 7. The drive assembly 10 is connected to the top of the rotating shaft 8 via a gear transmission pair. The connecting shafts 3 on both sides of the mounting frame 4 are connected to the rotating shaft 8 via bevel gear sets, allowing for angle adjustment of the mounting frame 4.

[0028] Preferred solutions include Figure 3 As shown, a cross-shaped mounting base 14 is welded to the bottom of the support column 2. A 12mm diameter threaded hole is opened at the corresponding position of the mounting base 14, and M10 stainless steel mounting bolts 15 are used for through-hole connection and fixation. Triangular support blocks 16 are welded to both sides of the upper end face of the mounting base 14. The inner side of the support blocks 16 fits against the outer wall of the support column 2, and the fillet weld enhances the overturning stability of the support column 2, enabling it to withstand lateral wind forces with wind speeds ≤25m / s.

[0029] Preferred solutions include Figure 4 As shown, a 40mm diameter rotating shaft 8 is arranged parallel inside the support column 2. The surface of the shaft is hardened to enhance its wear resistance. Three sets of connecting shafts 3 are equidistantly arranged along the height direction on the inner wall of the support column 2, with a spacing of 50cm between adjacent connecting shafts 3. A driving bevel gear 9 is fixed to the outer wall of the rotating shaft 8, and a driven bevel gear 6 is fixed to the end of the connecting shaft 3. The meshing clearance between the two gears is controlled at 0.1-0.2mm. When the rotating shaft 8 rotates, it drives the driven bevel gear 6 and the connecting shaft 3 to rotate synchronously through the bevel gear pair, achieving a transmission efficiency of over 90%.

[0030] Preferred solutions include Figure 4As shown, an inverted T-shaped groove with a depth of 30mm is formed on the inner wall of the mounting frame 4, and a countersunk hole 11 with a diameter of 10mm is formed at the bottom of the groove.

[0031] Preferred solutions include Figure 4 As shown, a 2mm thick EVA protective pad 17 is bonded to the inner wall of the mounting frame 4 slot with waterproof adhesive. The surface of the protective pad 17 has anti-slip texture. When the photovoltaic panel module 5 is snapped into the inner side of the protective pad 17, the protective pad 17 can buffer the vibration caused by water surface fluctuations, while increasing the coefficient of friction to prevent the photovoltaic panel module 5 from shaking inside the mounting frame 4.

[0032] Preferred solutions include Figure 2 and Figure 4 As shown, the drive assembly 10 includes a worm gear 101, a drive motor 102, and a worm wheel 103.
