Description

Technical Field

[0001] This invention relates to the field of floating photovoltaic equipment technology, and in particular to a floating photovoltaic support system. Background Technology

[0002] Floating photovoltaic (PV) refers to a photovoltaic power station construction method that installs PV power generation module arrays on the surface of natural or artificial water bodies with a certain depth using a dedicated support structure system to generate solar power. Its core feature is the entire power generation unit. As a complete engineering structure, the long-term accuracy of its spatial positioning, the overall safety and stability of the structural system, and the effective maintenance of the pre-set working posture of the power generation unit all highly depend on the state of the water environment below it. Because the water level in natural environments is not static and constant, but continuously undergoes uncontrollable changes driven by various internal and external factors such as natural precipitation, evaporation, human-induced water discharge, tidal rises and falls, and regional climate and hydrological conditions, the water surface fluctuates greatly during severe weather. Excessive water level can cause water to enter the PV modules, damaging their performance. Furthermore, large water fluctuations can impact the installation position of the PV modules, affecting their installation stability.

[0003] In addition, the depth of the water directly determines the magnitude of the buoyancy exerted by the water on the floating support structure of the photovoltaic system, the distribution of the buoyancy, and the overall balance between the system's gravity and buoyancy. At the same time, water depth information is also closely related to key factors such as the underwater topography of the photovoltaic facility's location, the possible depth of siltation, and the safe distance between the bottom of the support structure and underwater obstacles. Therefore, water depth is also very important for the design of floating photovoltaic systems. It can ensure that the inherent correlation performance of the water surface structure system with the continuous changes of key environmental parameters is effectively captured, monitored, and incorporated into the management feedback chain. This provides irreplaceable basic state information support for ensuring the safety and reliability of the floating photovoltaic system's structural spatial state, the effectiveness of its preset functions, and the stability of its long-term service in complex and changing aquatic environments.

[0004] Patent CN118651344B discloses a floating photovoltaic mooring equipment, mooring system, and installation method. The technical solution of this patent includes a buffer component, a sliding component, an adaptive retraction component, and a vertically arranged pile frame assembly. A vertically perforated sliding frame is set on the pile frame assembly. A buffer component is installed at each of the upper and lower ends of the perforated sliding frame. The sliding component is slidably installed in the perforated sliding frame, located between the two buffer components. The sliding component moves up and down in the perforated sliding frame as the sea level rises or falls. The sliding component is connected to the adaptive retraction component, which is connected to the photovoltaic support. However, this patent is prone to water entering the photovoltaic system when the water surface fluctuates too much, causing damage. At the same time, excessive water surface fluctuations can also affect the installation stability of the photovoltaic module. Summary of the Invention

After the two enclosures are closed, the lifting mechanism will automatically control the upper plate to lift the photovoltaic panel upward and raise the height of the photovoltaic panel. During the lifting process, the two enclosures will automatically open, which can prevent the photovoltaic panel from being soaked in water and prevent the enclosures from affecting the normal operation of the photovoltaic panel. It can ensure that the photovoltaic panel will not be affected when the water level rises.

[0021] (3) The present invention uses the buoyancy of water to push the floating rod to rise, and then monitors the water level by measuring the height of the floating rod. Attached Figure Description

Detailed Implementation

[0033] The technical solution of the present invention will be further described below in conjunction with specific embodiments. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0034] An embodiment provides a floating photovoltaic system, as shown in the attached figure. Figure 1 Appendix Figure 2 Appendix Figure 4 To be continued Figure 10 As shown, the supporting system includes a photovoltaic module 2, a photovoltaic support and protection device 3, a lifting mechanism 4, a balancing mechanism 5, and two sets of water level monitoring components 1. The photovoltaic support and protection device 3 includes a base plate 303, two surrounding plates 310, an upper plate 313, a lifting component, and a pushing component. The upper plate 313 is placed parallel above the base plate 303, and the photovoltaic module 2 is installed on the upper plate 313. The two surrounding plates 310 are symmetrically installed on both sides of the photovoltaic module 2. The two surrounding plates 310 are slidably connected to the upper plate 313. Each surrounding plate 310 is provided with a set of pushing components, and each pushing component is connected to a lifting component. Both lifting components are installed on the base plate 303. The two sets of lifting components rise and drive the pushing components to push the two surrounding plates 310 to enclose the photovoltaic module.

[0035] In the embodiments, as shown in the appendix Figure 2 -Appendix Figure 9As shown, the lifting assembly includes a lifting rod 302, which is slidably mounted on a base plate 303 in a vertical direction. A float plate 301 is fixedly mounted on the lower part of the lifting rod 302, located below the base plate 303. A limiting ring 311 is fixedly mounted on the top outer surface of each lifting rod 302. The diameter of the outer surface of the limiting ring 311 is larger than the diameter of the sliding hole of the lifting rod 302. The limiting ring 311 is coaxial with the lifting rod 302. The limiting ring 311 prevents the lifting rod 302 from detaching during the lifting process. The base plate 303; the pushing assembly includes a push rod 308, and two first sliding grooves 306 are symmetrically arranged on the lower side of the upper plate 313. The push rod 308 is slidably installed on the inner wall of the first sliding groove 306, and the push rod 308 is slidably connected to the lower side of the upper plate 313. A driving block 307 is fixedly installed on the lower side of the push rod 308, and a first connecting rod 305 is rotatably installed on the side of the driving block 307. A first connecting shaft 312 is rotatably installed on the end of the first connecting rod 305 away from the driving block 307, and the first connecting shaft 312 is fixedly installed on the outer surface of the lifting rod 302. (See attached image) Figure 3 Appendix Figure 5 To be continued Figure 9 As shown, the upper plate 313 has two sets of rectangular through holes on its upper side. These two sets of rectangular through holes are symmetrically distributed along the length of the upper plate 313 with the photovoltaic module 2 as the center, and are on the same straight line as the photovoltaic module 2. Two surrounding plates 310 are slidably mounted on the inner walls of the two rectangular through holes in the upper plate 313. A movable block 309 is fixedly mounted on the lower side of each of the two surrounding plates 310. The movable block 309 is slidably mounted on the inner wall of the rectangular through hole in the upper plate 313 and can slide along the rectangular through hole. During movement, the push rod 308 contacts the movable block 309 and pushes it. 09 drives the enclosure 310 to move; the upper plate 313 has two second sliding grooves 314 symmetrically arranged on the upper side in the width direction. A first fixed shaft 315 is fixedly installed on the inner wall of each second sliding groove 314. Each enclosure 310 is slidably installed between the two second sliding grooves 314. Two sections of first springs 316 are wound on the outer surface of each first fixed shaft 315. The two sections of first springs 316 are located on the outer side of the two enclosures 310. One end of each set of first springs 316 is fixedly installed on the outer surface of the first fixed shaft 315, and the other end is fixedly installed on the back of the enclosure 310. Each lifting rod 302 has a limiting ring 311 fixedly installed on its outer surface. The diameter of the outer surface of the limiting ring 311 is larger than the diameter of the outer surface of the lifting rod 302, and the limiting ring 311 is coaxial with the lifting rod 302. Mounting blocks 403 are fixedly installed on the two side panels 310 respectively. A contact switch 404 is fixedly installed on the mounting block 403 of one side panel 310, while no contact switch 404 is installed on the mounting block 403 of the other side panel 310. The contact switch 404 is used to control the working state of the lifting mechanism.

[0036] After the invention is installed on the water surface, the float plate 301 floats up under the buoyancy of the water. When the water level rises, the float plate 301 rises with the water level, thereby lifting the lifting rod 302. When the lifting rod 302 rises, it will give a thrust to the corresponding first connecting rod 305, and push the push rod 308 to slide along the first sliding groove 306 through the first connecting rod 305. When the push rod 308 moves in the first sliding groove 306, it will push the moving block 309 to drive the surrounding plate 310 to move, thereby driving the two surrounding plates 310 to move closer to each other and close together to surround the photovoltaic module 2, thereby preventing water from entering and damaging the photovoltaic module 2. The two sets of enclosures move relative to each other under the action of the two sets of lifting components and pushing components. When the two enclosures 310 are connected, they will touch the contact switch 404, thereby controlling the lifting mechanism to work. The lifting mechanism drives the upper plate 313 to rise. During the rising process, the push rod 308 is driven to slide back to its original position through the first connecting rod 305. At this time, the enclosure 310 has no pushing force and moves back under the action of the first spring 316, thereby opening. This will not affect the normal operation of the photovoltaic module 2.

[0037] In the embodiments, such as Figures 1 to 4 , Figure 7 As shown, the lifting mechanism 4 includes mounting cylinders 401 and electric telescopic rods 406. Multiple mounting cylinders 401 are symmetrically fixed to the bottom surface of the base plate 303. Each mounting cylinder 401 contains a set of electric telescopic rods 406. A sliding plate 405 is fixedly installed at the output end of each electric telescopic rod 406. The sliding plate 405 is slidably mounted on the inner wall of the mounting cylinder 401, and the outer diameter of the sliding plate 405 is equal to the inner diameter of the mounting cylinder 401. A lifting shaft 402 is fixedly installed on the upper side of the sliding plate 405 and is fixedly connected to the upper plate 313. To reduce costs, it is also possible to selectively install several sets of electric telescopic rods 406 in only a few sets, instead of installing guide rods directly in the other mounting cylinders 401. The contact switch 404 is electrically connected to each set of electric telescopic rods 406. One or more sets of contact switches 404 can be installed. The signal line of the contact switch 404 can pass through the lifting shaft 402 and connect to the electric telescopic rod 406. When a mounting block 403 is contacted, the contact switch 404 sends an electrical signal to the electric telescopic rod 406. The electric telescopic rod 406 then drives the lifting shaft 402 to rise via the sliding plate 405. The lifting shaft 402 then lifts the upper plate 313, thereby increasing the height of the photovoltaic module 2. At this time, the two enclosure plates 310 separate. The electric telescopic rod 406 stops working after 10 minutes of operation.

[0038] In the embodiments, such as Figure 1 and Figure 10As shown, two sets of water level monitoring components 1 are symmetrically installed on the base plate 303. Each set of water level monitoring components 1 includes a float 101 and a scale 104. A marker 103 is fixedly installed at the top of the float 101. The float 101 is slidably installed on the base plate 303. A float ball 102 is fixedly installed at the bottom end of the float 101 below the base plate 303. The scale 104 is vertically arranged on one side of the float 101. The bottom of the scale 104 is fixed to the base plate 303 and parallel to the float 101. The marker 103 at the top of the float 101 extends horizontally to the scale surface of the scale 104 and points to the scale value on the scale 104. Two mounting holes 304 are provided on the base plate 303, and the two floats 101 are slidably installed in the corresponding mounting holes 304. The mounting cylinder 401 is fixedly installed at the bottom of the water. Then, under the buoyancy of the water, the float ball 102 rises upward, which in turn drives the float rod 101 to rise. At this time, the marker 103 on the float rod 101 gradually moves away from the bottom plate 303. The distance the float rod 101 rises is measured by the scale 104 on the bottom plate 303. The water level is then measured by measuring the height the float rod 101 rises. The balancing mechanism 5 includes multiple side panels 501 and balancing components. All side panels 501 are fixedly installed on the upper plate 313, and each side panel 501 is connected to a set of balancing components.

[0039] In the embodiments, such as Figures 6 to 9 As shown, the balancing mechanism 5 includes multiple sets of balancing components dispersed around the upper plate 313. Each set of balancing components includes a side panel 501 and a turntable 503. The side panel 501 is fixed to the upper base plate 313. A second connecting shaft 502 is rotatably mounted on the top of the side panel 501. The turntable 503 is fixedly mounted on the end of the second connecting shaft 502 facing the surrounding plate 310. A third connecting shaft 504 is fixedly mounted on the side of the turntable 503 facing the surrounding plate 310. A second connecting rod 505 is rotatably mounted on the outer surface of the third connecting shaft 504. The end of the second connecting rod 505 away from the third connecting shaft 504 is rotatably mounted on... There is a fourth connecting shaft 506, a connecting block 512 is fixedly installed on the side of the fourth connecting shaft 506, a sliding block 510 is fixedly installed on the lower side of the connecting block 512, and a balance block 511 is fixedly installed on the sliding block 510; a fixed frame 507 is fixedly installed on the upper plate 313, a second fixed shaft 508 is fixedly installed on the inner wall of the fixed frame 507, the second fixed shaft 508 is slidably connected to the sliding block 510, a second spring 509 is wound around the outer surface of the second fixed shaft 508, one end of the second spring 509 is fixedly installed on the outer surface of the second fixed shaft 508, and the other end of the second spring 509 is fixedly installed on the sliding block 510.

[0040] When the water surface is uneven and impacts the lifting shaft 402, causing vibration, the vibration of the lifting shaft 402 is transmitted to the upper plate 313. At this time, under the action of vibration, the turntable 503 rotates. The turntable 503 drives the connecting block 512 to move through the second connecting rod 505. The connecting block 512 drives the sliding block 510 to slide along the fixed frame 507, which in turn drives the balance block 511 to move in the opposite direction. The reverse movement of the balance block 511 balances off part of the impact force.

[0041] The installation process of this invention is as follows:

[0042] First, install the photovoltaic load-bearing protection device 3, fix the installation cylinder 401 at the bottom of the water, and place the base plate 303 above the water surface. Then, install the photovoltaic module 2. After the device is installed, both the floating ball 102 and the floating plate 301 float on the water surface. When the water level fluctuates, the floating ball 102 moves up and down under the buoyancy of the water. When the water level rises, the floating ball 102 is lifted upward under the action of the buoyancy of the water, which in turn drives the floating rod 101 to rise. At this time, the marker 103 on the floating rod 101 gradually moves away from the base plate 303. The distance the floating rod 101 is lifted is measured by the scale 104 on the base plate 303. Then, the height of the water level is measured by measuring the height of the floating rod 101. Since the floating rod 101 always floats on the water surface, when the water level fluctuates, the floating rod 101 will move horizontally, thereby enabling real-time measurement and monitoring of the water level. Meanwhile, under the buoyancy of the water, the float plate 301 floats on the water surface. When the water level rises, the lower float plate 301 will also rise with the water surface. When the float plate 301 rises, it drives the lifting rod 302 to rise. The lifting rod 302 drives the first connecting rod 305 to move through the first connecting shaft 312. The first connecting rod 305 drives the push rod 308 to slide along the first sliding groove 306 through the driving block 307. Then, the push rod 308 pushes the moving block 309, which in turn drives the two enclosure plates 310 to move closer to each other and close together to surround the photovoltaic module 2, thereby preventing water from entering and damaging the photovoltaic module 2.

[0043] When the two enclosures 310 are closed until the mounting block 403 contacts the contact switch 404, the contact switch 404 is activated. The contact switch 404 sends an electrical signal to the electric telescopic rod 406. The electric telescopic rod 406 drives the lifting shaft 402 to rise through the sliding plate 405. The lifting shaft 402 drives the upper plate 313 to rise, thereby increasing the height of the photovoltaic module 2. At the same time, it controls the two enclosures 310 to separate. The electric telescopic rod 406 stops working after 10 minutes of operation.

[0044] When the water surface is uneven and impacts the lifting shaft 402, causing vibration, the vibration of the lifting shaft 402 is transmitted to the upper plate 313. At this time, the turntable 503 rotates under the action of vibration. The turntable 503 drives the connecting block 512 to move through the second connecting rod 505. The connecting block 512 drives the sliding block 510 to slide along the fixed frame 507, which in turn drives the balance block 511 to move. The movement of the balance block 511 balances off part of the impact force.

[0045] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. The scope of the invention is defined by the appended claims rather than the foregoing description, and therefore all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
