[0002] Offshore photovoltaic piles refer to pile foundation structures used to fix photovoltaic equipment, which are mainly divided into two types: pile-based fixed type and floating type. The pile-based fixed type is suitable for shallow waters, where photovoltaic equipment is fixed to the seabed by piling; while the floating type is suitable for deep waters, where photovoltaic equipment is installed on a floating body and fixed to the water surface by an anchoring system;

[0003] At present, offshore photovoltaic piles are generally fixed by screws, but seawater is corrosive to a certain extent. The screws will become brittle after being corroded by seawater for a long time. When the screws need to be removed, the screws corroded by seawater are prone to breakage after being subjected to force, causing the screws to be stuck in the fixing place of the offshore photovoltaic pile, making the removal of the offshore photovoltaic pile difficult.

[0034] Step 7: Maintenance monitoring: Regularly conduct corrosion inspection and structural health monitoring on photovoltaic piles, and use cathodic protection technology for maintenance.

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

[0036] When the present invention requires the installation of the photovoltaic pile, the bottom photovoltaic pile is first installed in the sea. After the installation of the bottom photovoltaic pile is completed, the upper photovoltaic pile can be spliced ​​on the top of the bottom photovoltaic pile. At this time, after the fixing component is put on the position where the two photovoltaic piles are close to each other, the pressure component is adjusted to move downward. When the pressure component moves downward, it pushes the fixing component to move toward the surface of the photovoltaic pile. The photovoltaic pile is squeezed and fixed by the fixing component. When the fixing component moves, it pushes the squeezing component to contact the splicing part of the two photovoltaic piles. While squeezing and fixing the photovoltaic pile, the splicing seam can be sealed. An anti-corrosion layer is provided on the surface of the photovoltaic pile. The photovoltaic pile adopts high-toughness corrosion-resistant concrete. Fibers such as glass fiber, carbon fiber, and polyester fiber are added during the production of concrete to improve the toughness of the concrete.

[0037] After the two photovoltaic piles of the present invention are spliced, the fixing ring is put on the splicing position of the two photovoltaic piles, and when the pressure component moves downward, the extrusion ring in the pressure component contacts the inclined frame, and the inclined surface of the inclined frame pushes the sliding rod to move toward the inside of the limit frame, and the sliding rod pushes the extrusion plate through the fixed plate to extrude and fix the photovoltaic pile when moving, thereby improving the convenience of installing the photovoltaic pile; when the extrusion ring is separated from the inclined frame, the sliding rod 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 photovoltaic pile needs to be fixed, the present invention twists the threaded rod to rotate inside the screw hole ring and move downward. When the threaded rod moves downward, the connection between the contact disk and the bent plate pushes the extrusion ring to move downward, so that the extrusion ring can push the inclined frame to move toward the surface of the limit frame to complete the fixing operation. When the photovoltaic pile needs to be disassembled, the threaded rod is twisted to move upward, and the pressure of the extrusion ring disappears. When the threaded rod breaks, the bent plate is knocked, and the bent plate rotates at the bottom of the extrusion ring and pushes the contact disk to contact the bottom of the threaded rod. At this time, the extrusion ring can be removed, avoiding the difficulty in disassembling the photovoltaic pile.

[0039] When the inclined frame of the present invention moves, it drives the push rod to move toward the inside of the fixed ring through the bracket. When the push rod moves, it pushes the arc plate to contact the surface of the photovoltaic pile. The photovoltaic pile is squeezed and fixed by the arc plate, so as to improve the stability of the photovoltaic pile after splicing. The arc plate is located at the splicing of two photovoltaic piles. The splicing of the photovoltaic pile is sealed by the arc plate to prevent seawater from entering the splicing of the photovoltaic pile and causing corrosion to it.

[0040] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0058] There are several prestressed steel bars 7. When the present invention needs to install the photovoltaic pile 1, the bottom photovoltaic pile 1 is first installed in the sea. After the bottom photovoltaic pile 1 is installed, the upper photovoltaic pile 1 can be spliced ​​on the top of the bottom photovoltaic pile 1. At this time, the fixing component 3 is put on the position where the two photovoltaic piles 1 are close to each other, and 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.

The photovoltaic pile 1 adopts high-toughness corrosion-resistant concrete. Glass fiber, carbon fiber, polyester fiber and other fibers are added in the concrete production to improve the toughness of the concrete. If the prestressed steel bars 7 are symmetrically arranged with the photovoltaic pile 1 as the center, the number of photovoltaic piles 1 is set to two, and the ends of the two photovoltaic piles 1 close to each other are in contact with each other.

[0059] The fixing component 3 includes a slide bar 18, the surface of the slide bar 18 is slidably connected to the inner wall of the limit frame 13, the end of the slide bar 18 is fixedly connected to the inclined frame 14, the end of the slide bar 18 away from the inclined frame 14 is fixedly connected to the fixing plate 15, the end of the fixing plate 15 away from the slide bar 18 is fixedly connected to the extrusion plate 11, and the end of the fixing plate 15 close to the slide bar 18 is fixedly connected to the spring 16;

[0060] A spring piece 17 is fixedly connected to the bottom of the inclined frame 14 , and one end of the spring piece 17 away from the inclined frame 14 is fixedly connected to the surface of the limiting frame 13 .

[0061] The inner wall of the limit frame 13 is connected to the inner wall of the fixing ring 10. After the two photovoltaic piles 1 are spliced, the fixing ring 10 is placed on the splicing of the two photovoltaic piles 1. When the pressure component 4 moves downward, the extrusion ring 22 in the pressure component 4 contacts the inclined frame 14, and the inclined surface of the inclined frame 14 pushes the slide bar 18 to move toward the inside of the limit frame 13. When the slide bar 18 moves, it pushes the extrusion plate 11 through the fixing plate 15 to squeeze and fix the photovoltaic pile 1, thereby improving the installation of the photovoltaic pile 1. For convenience, when the extrusion ring 22 is separated from the inclined frame 14, the slide bar 18 pulls the extrusion plate 11 to separate from the surface of the photovoltaic pile 1 through the elasticity of the spring 16, so as to disassemble the photovoltaic pile 1. There are four limit frames 13, and the four limit frames 13 are arranged with the fixing ring 10 as the center circumference. The end of the slide bar 18 away from the fixing plate 15 passes through the limit frame 13 and extends to the outer end of the limit frame 13, and the end of the spring 16 away from the fixing plate 15 is fixedly connected to the inner wall of the limit frame 13.

[0062] The end of the extrusion plate 11 extends to the outer end of the fixing ring 10. The fixing ring 10 is located at the end where the two photovoltaic piles 1 are close to each other.

[0065] The top of the contact plate 26 contacts the bottom of the threaded rod 21. When the photovoltaic pile 1 needs to be fixed, the threaded rod 21 is twisted to rotate inside the screw hole ring 20 and move downward. When the threaded rod 21 moves downward, the connection between the contact plate 26 and the bent plate 25 pushes the extrusion ring 22 to move downward, so that the extrusion ring 22 can push the inclined frame 14 to move toward 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 disappears. 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 pushes the contact plate 26 to contact the bottom of the threaded rod 21.

[0067] The end of the bracket 33 extends to the outer end of the ramp frame 14 , and two push rods 31 are provided at the end of the bracket 33 .

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

[0073] Among them, the plate is processed into cylindrical and conical shapes by a plate rolling machine to form the main structure of the photovoltaic pile.

[0074] Step 3: Welding process: Use submerged arc welding to weld the formed parts, the welding current is controlled at 200-400A, the voltage is controlled at 20-30V, and the welding speed is 10-20cm / min;

[0075] Among them, the weld is subjected to ultrasonic testing to ensure that there are no pores, slag inclusions and cracks inside the weld.

[0076] Step 4: Anti-corrosion treatment: sandblast the welded photovoltaic pile to remove the surface oxide layer and impurities;

[0077] The hot-dip galvanizing process is adopted, and the coating thickness is 200-400μm, which ensures the long-term corrosion resistance of the photovoltaic piles in the marine environment.

[0078] Step 5: Assembly inspection: Assemble the components into a complete photovoltaic pile structure by welding;

[0083] During use, when the photovoltaic pile 1 needs to be installed, the bottom photovoltaic pile 1 is installed in the sea first. After the bottom photovoltaic pile 1 is installed, the upper photovoltaic pile 1 can be spliced ​​on the top of the bottom photovoltaic pile 1. At this time, the fixing component 3 is put on the position where the two photovoltaic piles 1 are close to each other, and 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 moving, the fixing component 3 will push the squeezing component 5 to contact the splicing of the two photovoltaic piles 1, so that the photovoltaic pile 1 can be squeezed and fixed while the splicing seam can be sealed. The surface is provided with an anti-corrosion layer 2. The photovoltaic pile 1 adopts high-toughness corrosion-resistant concrete. Glass fiber, carbon fiber, polyester fiber and other fibers are added in the concrete production to improve the toughness of the concrete. After the two photovoltaic piles 1 are spliced, the fixing ring 10 is put on the splicing of the two photovoltaic piles 1. When the pressure component 4 moves downward, the extrusion ring 22 in the pressure component 4 contacts the inclined frame 14, and pushes the slide bar 18 to move toward the inside of the limit frame 13 through the inclined surface of the inclined frame 14. When the slide bar 18 moves, it pushes the extrusion plate 11 through the fixed plate 15 to extrude and fix the photovoltaic pile 1, thereby improving the convenience of the photovoltaic pile 1 during installation. When the extrusion ring 22 is separated from the inclined frame 14, The sliding rod 18 pulls the extrusion plate 11 apart from the surface of the photovoltaic pile 1 through the elasticity of the spring 16, so as to disassemble the photovoltaic pile 1. When the photovoltaic pile 1 needs to be fixed, the threaded rod 21 is twisted to rotate inside the screw hole ring 20 and move downward. When the threaded rod 21 moves downward, the connection between the contact plate 26 and the bent plate 25 pushes the extrusion ring 22 to move downward, so that the extrusion ring 22 can push the inclined frame 14 to move toward 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, and the bent plate 25 The bottom of the extrusion ring 22 is rotated and the contact disk 26 is pushed to contact the bottom of the threaded rod 21. At this time, the extrusion ring 22 can be removed to avoid difficulty in disassembling the photovoltaic pile 1. When the inclined frame 14 moves, it drives the push rod 31 to move toward the inside of the fixed ring 10 through the bracket 33. When moving, the push rod 31 pushes the arc plate 30 to contact the surface of the photovoltaic pile 1. The arc plate 30 is used to extrude and fix the photovoltaic pile 1 to improve the stability of the photovoltaic pile 1 after splicing. The arc plate 30 is located at the splicing of two photovoltaic piles 1. The arc plate 30 is used to seal the splicing of the photovoltaic pile 1 to prevent seawater from entering the splicing of the photovoltaic pile 1 and corroding it.
