Description

Technical Field

[0001] The present invention relates to the technical field of offshore photovoltaic piles, and specifically to an offshore photovoltaic pile and a production process. Background Art

[0002] An offshore photovoltaic pile refers to a pile foundation structure for fixing photovoltaic devices, which is mainly divided into two types: pile foundation fixed type and floating type. The pile foundation fixed type is applicable to shallow waters. The photovoltaic devices are fixed to the seabed by driving piles; while the floating type is applicable to deep waters. The photovoltaic devices are installed on floating bodies and fixed on the water surface through an anchoring system.

[0003] Currently, offshore photovoltaic piles are generally fixed by screws. However, seawater has certain corrosiveness. After the screws are corroded by seawater for a long time, they will become fragile. When the screws need to be disassembled, the corroded screws are prone to break under force, resulting in the screws getting stuck at the fixing part of the offshore photovoltaic pile, thus making the disassembly of the offshore photovoltaic pile difficult.

One end of the arc plate away from the push rod contacts the surface of the photovoltaic pile and is located at one end where two photovoltaic piles are close to each other.

[0021] Further, a production process of an offshore photovoltaic pile includes the following steps:

[0022] Step 1: Material preparation: High-strength steel is selected as the base material, and its chemical composition includes elements such as carbon, manganese, silicon, phosphorus, and sulfur. Among them, the carbon content is controlled at 0.12%-0.20%, and the manganese content is controlled at 1.20%-1.60%.

[0034] Step 7: Maintenance and monitoring: Regularly detect the corrosion condition of the photovoltaic pile and monitor the structural health, and use cathodic protection technology for maintenance.

[0035] The present invention has the following beneficial effects:

[0036] When installing the photovoltaic pile of the present invention, first install the bottom photovoltaic pile in the sea. After the installation of the bottom photovoltaic pile is completed, the upper photovoltaic pile can be spliced above the bottom photovoltaic pile. At this time, the fixing component is sleeved at the position where the two photovoltaic piles are close to each other, and then the pressure component is adjusted to move downward. When the pressure component moves downward, it pushes the fixing component to move towards the surface of the photovoltaic pile, and the photovoltaic pile is fixed by extrusion through the fixing component. When the fixing component moves, it will push the extrusion component to contact the splicing joint of the two photovoltaic piles, so as to not only fix the photovoltaic pile by extrusion, but also seal the splicing seam. An anti-corrosion layer is provided on the surface of the photovoltaic pile, and the photovoltaic pile is made of high-toughness corrosion-resistant concrete. Glass fiber, carbon fiber, polyester fiber and other fibers are added to the concrete production to improve the toughness of the concrete.

[0037] After the splicing of the two photovoltaic piles of the present invention is completed, the fixing ring is sleeved at the splicing joint of the two photovoltaic piles. When the pressure component moves downward, the extrusion ring in the pressure component contacts the inclined plane frame, and the slide bar is pushed into the inside of the limiting frame through the inclined plane of the inclined plane frame. When the slide bar moves, it pushes the extrusion plate to fix the photovoltaic pile through the fixing plate, improving the convenience of the photovoltaic pile during installation. When the extrusion ring is separated from the inclined plane frame, the slide bar pulls the extrusion plate to separate from the surface of the photovoltaic pile through the elasticity of the spring, so as to disassemble the photovoltaic pile.

[0038] When the present invention needs to fix the photovoltaic pile, twist the threaded rod to rotate and move downward inside the threaded hole ring. When the threaded rod moves downward, it pushes the extrusion ring to move downward through the connection of the contact disc and the bent plate, so that the extrusion ring can push the inclined plane frame to move towards the surface of the limiting frame to complete the fixing operation. When the photovoltaic pile needs to be disassembled, twist the threaded rod to move upward, and the pressure of the extrusion ring will disappear. When the threaded rod breaks, knock on the bent plate. The bent plate rotates at the bottom of the extrusion ring and pushes the contact disc to contact the bottom of the threaded rod. At this time, the extrusion ring can be removed to avoid difficult disassembly of the photovoltaic pile.

[0039] When the inclined plane frame of the present invention moves, it drives the push rod to move into the inside of the fixing ring through the bracket. When the push rod moves, it pushes the arc plate to contact the surface of the photovoltaic pile, and the photovoltaic pile is fixed by extrusion using the arc plate, improving the stability of the photovoltaic pile after splicing. And the arc plate is located at the splicing joint of the two photovoltaic piles, and the splicing joint of the photovoltaic pile is sealed by using the arc plate to prevent seawater from entering the splicing joint of the photovoltaic pile and causing corrosion.

[0040] Of course, it is not necessary for any product implementing the present invention to achieve all the above-mentioned advantages at the same time. Brief Description of the Drawings

After the installation of the bottom photovoltaic pile 1 is completed, the upper photovoltaic pile 1 can be spliced above the bottom photovoltaic pile 1. At this time, the fixing component 3 is sleeved on the position where the two photovoltaic piles 1 are close to each other, and then the pressure component 4 is adjusted to move downward. When the pressure component 4 moves downward, it pushes the fixing component 3 to move towards the surface of the photovoltaic pile 1, and the photovoltaic pile 1 is squeezed and fixed by the fixing component 3. When the fixing component 3 moves, it will push the extrusion component 5 to contact the splicing part of the two photovoltaic piles 1, so as to squeeze and fix the photovoltaic pile 1 and seal the splicing seam at the same time.

One end of the fixing plate 15 away from the sliding rod 18 is fixedly connected with a pressing plate 11. One end of the fixing plate 15 close to the sliding rod 18 is fixedly connected with a spring 16;

[0060] The bottom of the inclined plane frame 14 is fixedly connected with an elastic sheet 17. One end of the elastic sheet 17 away from the inclined plane frame 14 is fixedly connected with the surface of the limit frame 13.

[0061] The inner wall of the limit frame 13 is interconnected with the inner wall of the fixing ring 10. After the two photovoltaic piles 1 of the present invention are spliced, the fixing ring 10 is sleeved on the splicing part of the two photovoltaic piles 1. When the pressure part 4 moves downward, the pressing ring 22 in the pressure part 4 contacts the inclined plane frame 14, and the sliding rod 18 is pushed into the interior of the limit frame 13 through the inclined plane of the inclined plane frame 14. When the sliding rod 18 moves, the pressing plate 11 is pushed through the fixing plate 15 to squeeze and fix the photovoltaic pile 1, improving the convenience of installation of the photovoltaic pile 1. When the pressing ring 22 is separated from the inclined plane frame 14, the sliding rod 18 pulls the pressing plate 11 away from the surface of the photovoltaic pile 1 through the elasticity of the spring 16 for disassembly of the photovoltaic pile 1. The number of the limit frames 13 is set to four, and the four limit frames 13 are arranged in a circumferential manner with the fixing ring 10 as the center. One end of the sliding rod 18 away from the fixing plate 15 penetrates through the limit frame 13 and extends to the outer end of the limit frame 13. One end of the spring 16 away from the fixing plate 15 is fixedly connected with the inner wall of the limit frame 13.

[0062] One end of the pressing plate 11 extends to the outer end of the fixing ring 10. The fixing ring 10 is located at one end where the two photovoltaic piles 1 are close to each other. The inner wall of the fixing ring 10 contacts the surface of the photovoltaic pile 1. One end of the pressing plate 11 away from the fixing plate 15 contacts the surface of the photovoltaic pile 1.

[0064] The lower surface of the pressing ring 22 contacts the lower surface of the inclined plane frame 14. One end of the threaded rod 21 extends to the outer end of the threaded hole ring 20.

[0065] The top of the contact disk 26 contacts the bottom of the threaded rod 21. When the present invention needs to fix the photovoltaic pile 1, the threaded rod 21 is twisted to rotate and move downward inside the screw hole ring 20. When the threaded rod 21 moves downward, it pushes the extrusion ring 22 to move downward through the connection between the contact disk 26 and the bent plate 25, so that the extrusion ring 22 can push the inclined plane frame 14 to move towards the surface of the limit frame 13 to complete the fixing operation. When the photovoltaic pile 1 needs to be disassembled, the threaded rod 21 is twisted to move upward, and the pressure of the extrusion ring 22 will disappear. When the threaded rod 21 breaks, the bent plate 25 is knocked. The bent plate 25 rotates at the bottom of the extrusion ring 22 and simultaneously pushes the contact disk 26 to contact the bottom of the threaded rod 21.

[0068] The two push rods 31 are symmetrically arranged with the bracket 33 as the center. When the inclined plane frame 14 of the present invention moves, the push rod 31 is driven by the bracket 33 to move towards the inside of the fixing ring 10. When the push rod 31 moves, it pushes the arc plate 30 to contact the surface of the photovoltaic pile 1, and the arc plate 30 is used to squeeze and fix the photovoltaic pile 1 to improve the stability after the splicing of the photovoltaic pile 1. The arc plate 30 is located at the splicing place of the two photovoltaic piles 1, and the arc plate 30 is used to seal the splicing place of the photovoltaic pile 1 to prevent seawater from entering the splicing place of the photovoltaic pile 1 and causing corrosion to it. The end of the push rod 31 away from the bracket 33 penetrates through the fixing ring 10 and extends to the inside of the fixing ring 10.

After the installation of the bottom photovoltaic pile 1 is completed, the upper photovoltaic pile 1 can be spliced above the bottom photovoltaic pile 1. At this time, the fixing component 3 is sleeved at the position where the two photovoltaic piles 1 are close to each other, and then the pressure component 4 is adjusted to move downward. When the pressure component 4 moves downward, it pushes the fixing component 3 to move toward the surface of the photovoltaic pile 1, and the photovoltaic pile 1 is squeezed and fixed by the fixing component 3. When the fixing component 3 moves, it will push the extrusion component 5 to contact the splicing part of the two photovoltaic piles 1, so as to squeeze and fix the photovoltaic pile 1 and seal the splicing seam at the same time.
