Description

Technical Field

[0001] This utility model relates to the field of photovoltaic support technology, specifically to a fishery photovoltaic support with adjustable installation height. Background Technology

[0002] Aquaculture photovoltaic (PV) support structure is a type of support used to install photovoltaic power generation systems in aquaculture areas. It combines the functions of photovoltaic power generation and aquaculture, providing stable support for the PV system while avoiding excessive occupation of aquatic resources. By installing PV panels on top of the support structure, aquaculture can still be carried out below the water, achieving the symbiotic development of aquaculture and solar power generation. The shading effect of the PV panels can reduce water evaporation, lower water temperature, and improve the aquatic ecological environment.

[0003] Chinese Patent Publication No. CN209787091U discloses an easy-to-install solar panel support for fisheries, comprising a support column, with fixed feet fixedly installed at the bottom of each support column, a connecting plate fixedly installed on the left side of each support column, and a connecting seat movably installed on the top of each support column. The connecting seat and the support column are connected by a connecting shaft, and a pipe frame is fixedly installed on the top of each connecting seat. The pipe frame has fixing holes at both its top and bottom, and a fixing plate is fixedly installed at the bottom of the pipe frame, located on the left side of the support column and in front of the fixing holes. Limit holes are provided on the front of each fixing plate. This easy-to-install solar panel support for fisheries allows for faster and more convenient installation. Angle adjustments can be quickly completed during installation, increasing the installation speed and saving time and effort for installers. Furthermore, after installation, it effectively protects the wiring and extends the lifespan of the solar panels.

[0004] The aforementioned patent mentions that the installation of the fishery photovoltaic bracket only involves a quick adjustment of the angle. Since fishery photovoltaic brackets are mostly installed around fish ponds, reservoirs, and other water bodies, the area around these bodies of water is prone to natural elevation differences due to factors such as water level fluctuations, changes in soil moisture content, and uneven distribution of underwater silt layers. If the elevation difference of the foundation is too large, the installers need to perform pretreatment by raising the ground level or excavating the foundation, which not only prolongs the construction period but also easily damages the aquatic ecosystem and affects fishery production. Therefore, we propose a fishery photovoltaic bracket with an adjustable installation height. Utility Model Content

[0005] To address the aforementioned issues, a height-adjustable photovoltaic (PV) support for fisheries is provided. A lifting mechanism drives the PV panels to vertically displace on the support base, allowing for flexible adjustment of the installation height to adapt to different terrains.

Detailed Implementation

[0024] To further understand the features, technical means, and specific objectives and functions achieved by this utility model, the following detailed description of this utility model is provided in conjunction with the accompanying drawings and specific embodiments.

[0025] See Figure 1 and Figure 2 As shown, a height-adjustable photovoltaic support for fisheries includes a support base 1, a photovoltaic panel 11 mounted above the support base 1, and auxiliary support legs 2 on the support base 1. A lifting mechanism for driving the photovoltaic panel 11 to move vertically is provided between the support base 1 and the photovoltaic panel 11. A displacement mechanism for driving the support legs 2 to move linearly outside the support base 1 is provided between the support base 1 and the support legs 2. The lifting mechanism includes a support assembly and a first transmission assembly. The support assembly is located between the support base 1 and the photovoltaic panel 11 and is used to drive the photovoltaic panel 11 to move vertically. The first transmission assembly is located between the support base 1 and the support assembly and is used to transmit external force to the support assembly.

[0026] Specifically, when adjusting the installation height of the aquatic photovoltaic support bracket, rotational force is input through knob 26, which is transmitted to the support component via the first transmission component. This causes the support component to drive the photovoltaic panel 11 to adjust its height, keeping the photovoltaic panel 11 within the preset optimal installation height range to maximize power generation efficiency. Height adjustment eliminates the need for foundation leveling, avoiding the cumbersome pre-treatment operations required due to significant differences in foundation elevation, and reducing damage to the aquatic ecosystem.

[0027] During the height adjustment of the photovoltaic panel 11, the displacement mechanism can synchronously drive the support leg 2 to move outside the support base 1, so that the support leg 2 provides auxiliary support to the support base 1. The displacement of the support leg 2 outside the support base 1 can effectively distribute the load of the support base 1 through auxiliary support when the height of the photovoltaic panel 11 is adjusted, prevent excessive pressure in local areas, ensure the balance of the fishery photovoltaic support after height adjustment, and reduce the risk of tilting or uneven stress on the support.

[0028] See Figure 3 and Figure 4 As shown, the support assembly includes a support column 21, a screw 22, and a guide rod 23. The support column 21 is disposed above the support base 1 and is fixedly connected to the photovoltaic panel 11. The screw 22 is rotatably disposed on the support base 1 and is threadedly connected to the support column 21. The guide rod 23 is fixedly connected to the support base 1 and slides with the support column 21. The first transmission assembly includes a first gear plate 24, a second gear plate 25, and a knob 26. The first gear plate 24 is rotatably disposed on the support base 1 and is fixedly connected to the screw 22. The second gear plate 25 is rotatably disposed on the support base 1 and meshes with the first gear plate 24. The knob 26 is rotatably disposed on the support base 1 and is fixedly connected to the second gear plate 25.

[0029] Specifically, a sliding guide pair is formed between the guide rod 23 and the support column 21. A deformable folded corrugated cover 3 is connected between the support base 1 and the support column 21. The folded corrugated cover 3 can block external dust and prevent external dust from interfering with the threaded connection between the screw 22 and the support column 21. The folded corrugated cover 3 can extend as the support column 21 moves.

[0030] When adjusting the installation height of the photovoltaic support frame, the installer can use tools such as an electric wrench to rotate knob 26, causing knob 26 to drive the second gear 25 to rotate. Through the meshing transmission between the second gear 25 and the first gear 24, the second gear 25 can drive the first gear 24 to rotate, which in turn drives the screw 22 to rotate. The guide rod 23 and the support column 21 form a sliding guide pair, which can limit the synchronous rotation of the support column 21 with the screw 22; at the same time, the support column 21 and the screw 22 are connected by threads, so that the support column 21 can move stably upward along the screw 22, thereby driving the photovoltaic panel 11 to move and realize the adjustment of the installation height of the photovoltaic panel 11.

[0031] By using the support column 21 to drive the photovoltaic panel 11 to be stably adjusted to the appropriate height, it can be ensured that the photovoltaic panel 11 can be installed at the optimal angle in various environments, avoiding the cumbersome pre-treatment operations required due to excessive differences in ground elevation, and reducing the damage to the aquatic ecological environment during the installation of the fishery photovoltaic support.

[0032] See Figures 3-6 As shown, the displacement mechanism includes a reduction assembly, a second transmission assembly, a guide assembly, and a telescopic member 27. The reduction assembly is rotatably mounted on the support base 1. The second transmission assembly is rotatably mounted on the support base 1 and is used to convert the rotational force of the reduction assembly into a linear movement force. The guide assembly is located between the support base 1 and the support leg 2 and is used to cooperate with the second transmission assembly to drive the support leg 2 to move linearly. The telescopic member 27 is hinged at both ends to the support base 1 and the support leg 2, respectively. The reduction assembly includes a worm 28 and a worm wheel 29. The worm 28 is rotatably mounted on the support base 1, and one end of the worm 28 is connected to the second tooth... The disk 25 is fixedly connected; the worm gear 29 is rotatably mounted on the support base 1 and meshes with the worm 28; the second transmission assembly includes a third gear disk 210 and a toothed plate 211; the third gear disk 210 is rotatably mounted on the support base 1 and is fixedly connected to the worm gear 29; the toothed plate 211 meshes with the third gear disk 210; the guide assembly includes a support rod 212 and a slide groove 213; one end of the support rod 212 is fixedly connected to the support leg 2, and the toothed plate 211 is fixedly installed on the top surface of the support rod 212; the slide groove 213 is opened on the contact surface between the support base 1 and the support rod 212, and the slide groove 213 slides with the support rod 212.

[0033] Specifically, the telescopic component 27 consists of interlocking and relatively sliding inner and outer connecting rods. The support rod 212 and the slide groove 213 form a sliding guide pair, and the cross-sectional shape of the support rod 212 is rectangular.

[0034] While the second gear 25 drives the first gear 24 to rotate, the second gear 25 simultaneously drives the worm 28 to rotate. Through the meshing transmission between the worm wheel 29 and the worm 28, the worm 28 can drive the worm wheel 29 to rotate, which in turn drives the third gear 210 to rotate. Since the third gear 210 meshes with the toothed plate 211, the third gear 210 can push the toothed plate 211 to move. At this time, the toothed plate 211 drives the support rod 212 to slide along the slide groove 213. The support rod 212 and the slide groove 213 form a sliding guide pair, and the cross-section of the support rod 212 is rectangular, ensuring that the support rod 212 slides stably along the slide groove 213, thereby pushing the support leg 2 to move outside the support base 1, increasing the support points of the support base 1.

[0035] When the support leg 2 moves, it pulls the telescopic component 27. The telescopic component 27 consists of two connecting rods forming a sliding guide pair. Under the pull of the support leg 2, the telescopic component 27 extends, allowing it to cooperate with the support leg 2 to provide auxiliary support to the support base 1. Therefore, during the height adjustment of the photovoltaic panel 11, the support leg 2 and the telescopic component 27 can enhance the stability of the support base 1, improve the wind and earthquake resistance of the photovoltaic bracket, reduce tilting or swaying during the adjustment process, and significantly improve the stability of the bracket after adjustment.

[0036] Working principle: When adjusting the installation height of the photovoltaic support frame, the knob 26 is rotated with the help of tools such as an electric wrench, so that the support column 21 can move upward along the screw 22, thereby driving the photovoltaic panel 11 to move and realize the adjustment of the installation height of the photovoltaic panel 11. At the same time, the support rod 212 pushes the support leg 2 to move outside the support base 1, increasing the support point of the support base 1. The telescopic component 27 extends under the pull of the support leg 2, so that the telescopic component 27 and the support leg 2 cooperate to form auxiliary support for the support base 1, improve the wind resistance and earthquake resistance of the photovoltaic support frame, reduce tilting or swaying during the adjustment process, and significantly improve the stability of the support frame after adjustment.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
