[0019] The principles and features of the present invention are described below with reference to the accompanying drawings. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.
[0020] Please see Figure 1-7 As shown in the figure, this embodiment provides a water surface photovoltaic support structure, such as... Figure 1-2 As shown, it includes a floating structure body 1, and the outer wall of the floating structure body 1 is provided with multiple dynamic balancing components 2; a photovoltaic module 3 is fixedly installed on the top of the floating structure body 1, and a rotating balancing component 4 is rotatably connected to the bottom of the floating structure body 1.
[0021] Reference Figure 2 As shown, the main body of the floating structure 1 includes a floating frame 101, combined with... Figure 5 As shown, the inner cavity of the floating frame 101 is provided with a cavity, and a partition 104 is fixedly installed in the inner cavity of the floating frame 101. The partition 104 divides the internal space of the floating frame 101 into two parts. At the same time, combined with Figure 2 and Figure 5 As shown, the dynamic balancing component 2 includes multiple water guide holes 21 formed on the outer wall of the floating frame 101. Multiple hollow sleeves 22 connected to the water guide holes 21 are fixedly installed on the inner wall of the floating frame 101. The hollow sleeves 22 are located below the partition plate 104. A first piston rod 23 is slidably installed in the inner cavity of the hollow sleeve 22. One end of the first piston rod 23 is fixedly connected to a second piston rod 24 inserted into the inner cavity of the water guide hole 21. Under normal conditions, the first piston rod 23 and the second piston rod 24 respectively seal the water guide hole 21 and the inner cavity of the hollow sleeve 22. When the floating frame 101 is placed in water, water is prevented from entering the inner cavity of the hollow sleeve 22 through the water guide hole 21. Conversely, when the first piston rod 23 and the second piston rod 24 are moved away from the water guide hole 21, external water can be drawn into the inner cavity of the hollow sleeve 22 through the water guide hole 21.
[0022] At the same time, combined Figure 3-5 As shown, a first connecting frame 25 is fixedly connected to the end of a plurality of first piston rods 23 away from the second piston rod 24. A second connecting frame 26 that is slidably connected to the top of a plurality of first connecting frames 25 is fixedly installed, and a balance plate 27 is fixedly installed at the end of a plurality of second connecting frames 26 that extends out of the outer wall of the floating frame 101. A limiting float 28 is fixedly installed at the horizontal centerline position of a plurality of balance plates 27. Under normal conditions, a plurality of first connecting frames 25 and second connecting frames 26 are synchronously attached to the end of the hollow sleeve 22 away from the water guide hole 21, and one end of a plurality of second connecting frames 26 extends out of the outer wall of the floating frame 101, so that a plurality of balance plates 27 and limiting floats 28 are in contact with the water surface, maintaining the stability of the floating frame 101 on the water surface.
[0023] Understandably, in actual use, when there are large waves on the water surface, as the waves impact the surface of the balance plate 27, the second connecting frame 26 is simultaneously subjected to force and moves into the inner cavity of the floating frame 101. Then, the first connecting frame 25 pulls the second piston rod 24 and the first piston rod 23 to move within the inner cavity of the hollow sleeve 22 and the water guide hole 21, so as to draw water into the inner cavity of the hollow sleeve 22 through the water guide hole 21. This increases the weight of the bottom of the floating frame 101 on the side that is impacted, causing the center of gravity of the entire support to tilt slightly towards the side with waves, in order to balance the turbulence caused by the waves. The above settings allow the entire support to dynamically adjust its center of gravity according to the direction and force of the waves, so that the entire support can remain stable in the event of waves.
[0024] Furthermore, among which, refer to Figure 5 As shown, the top of the partition 104 is provided with multiple guide grooves 29, and multiple first connecting frames 25 are slidably installed in the inner cavity of the guide grooves 29. The inner cavity of the multiple guide grooves 29 is fixedly installed with guide rods 210 that are slidably connected to the first connecting frames 25. The purpose of this arrangement is to allow the guide grooves 29 and guide rods 210 to assist in limiting the movement range of the first connecting frames 25, so that the second connecting frame 26 and the first piston rod 23 are more stable when they move.
[0025] Furthermore, a first floating plate 102 is fixedly installed on the outer wall of the floating frame 101, and a plurality of second floating plates 103 are fixedly connected to the floating frame 101 on the top of the first floating plate 102. The plurality of second floating plates 103 are all kept on the same horizontal line as the horizontal center line of the limiting float 28, and the plurality of second floating plates 103 and the balance plate 27 are arranged in a ring-shaped and equidistant manner around the outer wall of the floating frame 101. The purpose of this arrangement is that when the floating frame 101 is placed in the water as a whole, the arrangement of the plurality of balance plates 27, the limiting strip 28 and the second floating plates 103 makes the floating frame 101 able to float stably on the water surface. This design, through the cooperation of the plurality of floating plates and the limiting structure, not only effectively enhances the stability of the device on the water surface, but also reduces swaying when encountering external force interference, ensuring that the device can work normally in various complex water surface environments.
[0026] Specifically, when the floating frame 101 is placed on the water surface, the first floating plate 102 provides initial buoyancy support through its bottom contact with the water. The second floating plate 103 is fixedly connected to the first floating plate 102 through its top, further enhancing the overall buoyancy and stability. The horizontal arrangement of the balance plate 27 and the limiting strip 28 allows the buoyancy of the entire device to be evenly distributed on the water surface, preventing tilting or overturning due to insufficient buoyancy on one side. In addition, this ring-shaped equidistant arrangement design ensures that the buoyancy of the device is uniform in any direction on the water surface, thereby further enhancing the device's resistance to wind and waves. In practical applications, this design allows the device to quickly return to a stable state even when impacted by external wind, waves, or water flow on the water surface, without affecting the normal function of the device.
[0027] Furthermore, as a further expansion of this plan, refer to Figure 6-7 As shown, the photovoltaic module 3 includes two semi-circular brackets 31 fixedly installed on the top of the floating frame 101. The two semi-circular brackets 31 are arranged in a cross-shaped manner on the top of the floating frame 101. Each of the two semi-circular brackets 31 has two arc-shaped limiting grooves 32 inside, and the two arc-shaped limiting grooves 32 are symmetrically arranged about the vertical center line of the semi-circular brackets 31. By making the two semi-circular brackets 31 cross-shaped installed on the top of the floating frame 101 and the arc-shaped limiting grooves 32 symmetrically arranged with respect to the vertical center line of the semi-circular brackets 31, the purpose of this arrangement is to increase the stability of the structure and provide more support points for the adjustment of the photovoltaic panel 34, so that the device can remain stable in different environments.
[0028] Furthermore, each of the multiple arc-shaped limiting grooves 32 has a support frame 33 rotatably mounted inside its cavity. Each of the multiple support frames 33 has a photovoltaic panel 34 fixedly mounted on its top in an inclined state. The horizontal center line of the support frame 33 is rotatably connected to the vertical center line of the arc-shaped limiting groove 32. Under normal conditions, the multiple support frames 33 are in an inclined state, and the tops of the multiple support frames 33 are close together, so that the multiple photovoltaic panels 34 are close to each other and form a cone-shaped support on the top of the floating frame 101. This allows the multiple photovoltaic panels 34 to collect light from multiple angles, improving the light energy collection efficiency. When the entire device is placed on the water surface, the multiple photovoltaic panels 34 can capture light from all directions, ensuring efficient energy collection under different lighting conditions. The purpose of this design is not only to enhance stability but also to significantly improve the light energy utilization rate.
[0029] Specifically, the support frame 33, through its rotatable connection with the arc-shaped limiting groove 32, allows the photovoltaic panel 34 to freely adjust its tilt angle according to changes in the direction of sunlight, thereby always maintaining the optimal state of sunlight reception. Whether it is morning, noon, or dusk, the photovoltaic panel 34 can be adjusted to the optimal angle to maximize the amount of light energy collected. This design ensures that the photovoltaic panel 34 can operate efficiently at any time of day, improving the overall efficiency of the photovoltaic device. In addition, this conical photovoltaic panel layout gives the device better wind resistance on the water surface. When the wind blows over the device, the conical structure can effectively guide the airflow, reduce the direct impact of the wind on the device, and prevent the device from tilting or being damaged. This structural design not only improves the stability of the photovoltaic device but also extends its service life.
[0030] More preferably, the top of the floating frame 101 is equipped with an electric screw 35 that is rotatably connected to the semi-circular bracket 31. The semi-circular bracket 31 is hinged to a first support rod 36 that is hinged to the support frame 33. A second support rod 37 is hinged to the first support rod 36. One end of the second support rod 37 is hinged to a threaded sleeve 38 that is sleeved on the electric screw 35.
[0031] Furthermore, an electric screw 35 rotatably mounted on the top of the floating frame 101 is rotatably connected to two semi-circular brackets 31. Multiple first support rods 36, each hinged to a support frame 33, are hinged to the inner wall of the semi-circular brackets 31. Second support rods 37 are hinged to the outer walls of each of the first support rods 36. One end of each of the second support rods 37 is hinged to a threaded sleeve 38 threadedly connected to the electric screw 35. In inclement weather, the user can activate the electric screw 35 to rotate it, causing the threaded sleeve 38 to move the second support rods 37 along the outer wall of the electric screw 35, thereby causing the second support rods... The change in the tilt angle of 37 causes a change in the tilt angle of the first support rod 36, which in turn causes the support frame 33 to deflect, changing the distance between the multiple photovoltaic panels 34. This causes the multiple photovoltaic panels 34 to gradually deflect towards the outer wall of the floating frame 101. During this process, as the photovoltaic panels move away from each other, the weight of the top of the floating frame 101 is distributed, thereby lowering the overall center of gravity of the device. This ensures that the entire device remains stable and less prone to tilting when encountering wind, waves, or other external forces, making it easier for the floating frame 101 to remain stable when it sways.
[0032] More preferably, it also includes a rotational balancing assembly 4, which includes a connecting rod 41. The connecting rod 41 is rotatably mounted on the bottom of the floating frame 101. The upper end of the connecting rod 41 is fixedly connected to the electric screw 35. Multiple connecting rods 42 are fixedly mounted in a ring at equal intervals around the connecting rod 41. One end of each connecting rod 42 is fixedly mounted with a padding blade 43.
[0033] Reference Figure 6 As shown, the rotational balancing assembly 4 includes a connecting rod 41 rotatably mounted on the bottom of the floating frame 101 and fixedly connected to the electric screw 35. Multiple connecting rods 42 are fixedly mounted in a ring-shaped manner on the outer wall of the connecting rod 41 at equal intervals. A padding blade 43 is fixedly mounted on one end of each of the multiple connecting rods 42. Specifically, rotating the electric screw 35 will cause the connecting rod 41 and the connecting rods 42 at the bottom to rotate together. As the connecting rods 42 rotate, the padding blade 43 also rotates in the water, thereby causing the entire device to start rotating. This ensures that the overall center of gravity of the device remains in a relatively stable state, preventing the device from becoming unstable and overturning due to changes in the center of gravity of the device during adjustment, combined with the effects of wind and waves. This further enhances the stability of the device in the water environment.
[0034] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
