Description

Technical Field

[0001] The present invention relates to the field of offshore photovoltaic operation platforms, and in particular to an offshore photovoltaic engineering operation platform. Background Art

[0002] As key infrastructure for offshore photovoltaic construction, offshore photovoltaic operation platforms have evolved through several stages. Early offshore photovoltaic operation platforms had relatively simple designs, often modified from traditional floating structures. These platforms primarily carried construction personnel and basic equipment, providing a relatively stable workplace for the installation and commissioning of offshore photovoltaic modules. With the continuous advancement of offshore photovoltaic technology, the functions of these platforms have gradually diversified, beginning to include material storage, transportation, and a degree of automated operation.

[0003] Currently, existing offshore photovoltaic project operation platforms have many shortcomings in practical application. First, in terms of platform scalability, most existing platforms are fixed structures, making it difficult to flexibly adjust and expand according to different construction needs. When encountering large-scale offshore photovoltaic projects, existing platforms may not provide sufficient operating area and storage space, resulting in chaotic material stacking during construction and affecting construction efficiency. Moreover, if the platform's operating range needs to be adjusted during construction, it often requires a considerable amount of time and resources to rebuild or modify, which seriously affects the project progress. Summary of the Invention

[0004] The purpose of the present invention is to provide an offshore photovoltaic engineering operation platform that combines a raft platform with several extended floating platform structures, can flexibly adjust the operating area according to different construction requirements, improve the versatility and adaptability of the platform, better meet the construction requirements of large-scale offshore photovoltaic projects, and improve construction efficiency and quality.

[0005] The present invention is achieved by the following measures: An offshore photovoltaic engineering operation platform, comprising a raft platform, on which a plurality of extended floating platforms in different directions are arranged, characterized in that the extended floating platform comprises a mounting frame arranged on the raft platform, a conveying mechanism is provided on the mounting frame, a floating plate stack is provided above the conveying mechanism and on the mounting frame, wherein a plurality of floating plates are stacked in the floating plate stack; The side of the first floating board is connected with an expansion platform.

[0006] The raft platform serves as a load-bearing platform, on which are mounted several extended floating platforms in different directions, which facilitates extension operations in different directions. At the same time, the raft platform also carries other operating equipment. The load-bearing capacity of the raft platform is greater than the total weight of the several extended floating platforms, operating personnel and carried equipment. Guardrails are arranged around the raft platform.

[0007] The specific features of the present invention also include: The floating plate is provided with a pair of through adjustment holes along its length, a winch is provided on the top of the floating plate stack, and the cable end of the winch passes through the adjustment holes of the plurality of spliced floating plates and is then fixedly provided on the side of the first floating plate; A pair of rectangular support blocks are provided at the bottom of the floating board, and the cables between the adjacent stacked floating boards are between the rectangular support blocks on both sides.

[0008] By providing the rectangular support blocks, space can be created between adjacent floating plates when they are stacked, making it easier for workers to sort out and place cables. Preferably, the cables of the winch are flexible ropes.

[0009] A limit column is provided on the inner side of the top of the floating plate stack, and a limit electromagnet is provided near the top of the limit column. The distance between the bottom end of the limit column and the conveying mechanism is greater than the thickness of the floating plate; A metal sleeve is provided at the center of the floating plate, and the metal sleeve is provided on the periphery of the limiting column; The top end of the metal sleeve is higher than the top surface of the floating plate, and the bottom end of the metal sleeve is higher than the bottom surface of the rectangular support block.

[0010] The distance between the bottom end of the limiting column and the conveying mechanism ensures that the floating plate can be normally conveyed out of the floating plate stack; At the same time, the position settings of the upper and lower ends of the metal sleeve ensure that when the adjacent water floating plates are stacked, the metal sleeves of the upper and lower water floating plates can be ended, thereby forming a magnetic attraction limit for the plurality of water floating plates through the limiting electromagnet; Cables are provided on the sides of several of the floating plates, and mounting side panels are provided on both the left and right sides of the floating plates. Metal plates and electromagnets corresponding to positions are respectively provided on the mounting side panels on both sides.

[0011] The cable is installed on the side of the water floating board through the installation fasteners, and the electromagnet is powered by the cable. At the same time, the length of the cable ensures that several water floating boards can be spread out and stored and stacked normally. During the spreading, storage and stacking of the water floating boards, the staff assists in combing the cables and cables to prevent the cables and cables from getting entangled.

[0012] The mounting side plate is provided with a pair of U-shaped grooves corresponding to the positions of the adjustment through holes, and the U-shaped grooves are provided with through holes corresponding to the adjustment through holes; The cable of the hoist passes through the through hole on one side, the adjustment through hole and the through hole on the other side in sequence; A plurality of mounting grooves are provided on the surface of the mounting side plate, and the metal plate is arranged in the mounting grooves. The positions and shapes of the mounting grooves are matched with the electromagnets.

[0013] The electromagnet can be inserted into the mounting groove to absorb the metal plate, thereby ensuring that adjacent floating plates are magnetically connected to the metal plate through the electromagnet.

[0014] The conveying mechanism includes a discharge conveyor belt and a delivery conveyor belt arranged on the mounting frame, and the floating plate stacking bin is arranged above the discharge conveyor belt and on the mounting frame; The floating plate stack includes a left plate, a right plate and a top plate arranged on the mounting frame, a discharge port is provided between the right plate and the conveying mechanism, and the height of the discharge port is greater than the thickness of the floating plate above the water.

[0015] The discharging conveyor belt transports the floating plate on the water, which is separated from the limiting pillar at the bottom, out of the floating plate stacking bin, and then passes through the delivery conveyor belt and falls onto the water surface; The height of the discharge port is greater than the thickness of the floating plate on the water, thereby ensuring that the floating plate on the water can be normally transported out of the floating plate stack.

[0016] An inclined roller guide frame is provided on the front end of the delivery conveyor belt and the mounting frame.

[0017] Cable guide wheels are provided inside the first U-shaped groove and the second U-shaped groove and on the upper and lower sides of the cable of the winch.

[0018] A metal mounting plate is provided on the side of the expansion platform.

[0019] When the extended floating platform is laid, the water floating board is first launched, the limit electromagnet is closed, and the discharging conveyor belt transports the water floating board that has separated from the limit column at the bottom from the floating board stacking bin. When the water floating board is transported to the launching conveyor belt, the discharging conveyor belt stops working, and the launching conveyor belt continues to transport the water floating board forward. After the cable between the front water floating board and the rear water floating board is laid, the discharging conveyor start belt transports the next water floating board from the floating board stacking bin, and the front water floating board continues to be transported by the launching conveyor belt and falls onto the sea surface after passing through the roller guide frame (several water floating boards fall onto the sea surface through the coordinated cooperation of the discharging conveyor belt, the launching conveyor belt and the staff, during which the cables on the side are paid out through the cable drum); After that, the floating plates are spread out. The winch reels in the cable, and the staff controls the floating plates on the side close to the raft platform. The winch brings the adjacent floating plates closer to each other by reeling in the cable until several floating plates are close to each other (manual arrangement is carried out during this period). At this time, the electromagnets of the adjacent floating plates enter the corresponding installation grooves. After that, the cables are energized, and the adjacent floating plates are magnetically connected to the metal plates through the electromagnets (matching electromagnets are provided on the side of the raft platform, and the floating plates on the side close to the raft platform are adsorbed on the electromagnets on the side of the raft platform). After several floating plates are spread out and connected, the expansion platform is dragged to the first floating platform, and the expansion platform is adsorbed on the electromagnet on the side of the first floating plate. When the extended floating platform is stored, the power supply of the cable is cut off, the winch pays out the cable to its initial length, the staff drags the floating board near the raft platform ashore, pulls the cable, shortens the length of the cable between the floating board and the winch, and then transports the floating board back to the floating board stacking bin through the conveying mechanism. Start the limit electromagnet, raise the floating plate and pass the metal sleeve through the limit column to be adsorbed on the limit electromagnet, then drag the next floating plate in turn, pull the cable, shorten the length of the cable between the floating plate and the winch, and similarly raise the floating plate and pass the metal sleeve through the limit column to adsorb the bottom of the metal sleeve of the floating plate that is already in place above, and then adjust the distance between the cables between adjacent floating plates in turn to complete the storage of several floating plates (the cables are stored through the cable reel during this period).

[0020] The beneficial effects of the present invention are as follows: by combining a raft platform with several extended floating platform structures, the present invention can flexibly adjust the operating area according to different construction requirements, improve the versatility and adaptability of the platform, better meet the construction requirements of large-scale offshore photovoltaic projects, and improve construction efficiency and quality.

The extended floating platforms include a mounting frame 1 disposed on the raft platform 12, the mounting frame 1 being provided with a conveying mechanism, a floating plate stack 4 being disposed above the conveying mechanism and on the mounting frame 1, wherein a plurality of floating plates 5 are stacked in the floating plate stack 4; The side of the first floating plate 5 is connected to an expansion platform 13 .

[0035] The raft platform 12 serves as a load-bearing platform, on which are mounted several extended floating platforms in different directions, which facilitates extension operations in different directions. At the same time, the raft platform 12 is also equipped with other operating equipment. The load-bearing capacity of the raft platform 12 is greater than the total weight of the several extended floating platforms, operating personnel and carried equipment. Guardrails are arranged around the raft platform 12.

[0036] A pair of through-holes are provided along the length of the floating plate 5. A winch 9 is provided on the top of the floating plate stack 4.

A pair of rectangular support blocks 501 are provided at the bottom of the floating plate 5 , and the cables 11 between the adjacent stacked floating plates 5 are located between the rectangular support blocks 501 on both sides.

[0037] By providing the rectangular support blocks 501 , space can be created between adjacent floating plates 5 when they are stacked, making it easier for workers to sort out and place the cables 11 . Preferably, the cables 11 of the winch 9 are flexible ropes.

[0038] A limit column 6 is provided on the inner side of the top of the floating plate stack 4, and a limit electromagnet 7 is provided near the top of the limit column 6.

[0039] The distance between the bottom end of the limiting column 6 and the conveying mechanism ensures that the floating plate 5 can be normally conveyed out of the floating plate stack 4; At the same time, the position settings of the upper and lower ends of the metal sleeve 503 ensure that when adjacent water floating plates 5 are stacked, the metal sleeves 503 of the upper and lower water floating plates 5 can be ended, thereby forming a magnetic limit for several water floating plates through the limit electromagnet 7; Cables are provided on the sides of the plurality of floating plates 5 , and mounting side plates 502 are provided on both the left and right sides of the floating plates 5 . Metal plates 508 and electromagnets 509 corresponding to the positions are provided on the mounting side plates 502 on both sides.

[0040] The cable is installed on the side of the water floating board 5 through the installation fasteners, and the electromagnet 509 is powered by the cable. At the same time, the length of the cable ensures that several water floating boards 5 can be spread out and stored and stacked normally. During the spreading and storage and stacking of the water floating boards 5, the staff assists in combing the cables and cables 11 to prevent the cables and cables 11 from getting entangled.

[0041] The mounting side plate 502 is provided with a pair of U-shaped grooves 504 corresponding to the positions of the adjustment holes, and the U-shaped grooves 504 are provided with through holes 506 corresponding to the adjustment holes; The cable 11 of the hoist 9 passes through the through hole 506 on one side, the adjustment through hole and the through hole 506 on the other side in sequence; A plurality of mounting grooves 507 are formed on the surface of the mounting side plate 502 , and the metal plates 508 are disposed in the mounting grooves 507 . The positions and shapes of the mounting grooves 507 match those of the electromagnets 509 .

[0042] The electromagnet 509 can be inserted into the installation groove 507 to absorb the metal plate 508, thereby ensuring that the adjacent floating plates 5 are magnetically connected to each other through the electromagnet 509 and the metal plate 508.

[0043] The conveying mechanism includes a discharge conveyor belt 2 and a delivery conveyor belt 3 provided on a mounting frame 1. A floating plate stacking bin 4 is provided above the discharge conveyor belt 2 and on the mounting frame 1. The floating plate stack 4 includes a left plate 401, a right plate 402 and a top plate 403 arranged on the mounting frame 1. A discharge port is provided between the right plate 402 and the conveying mechanism, and the height of the discharge port is greater than the thickness of the floating plate 5 on the water.

[0044] The discharging conveyor belt 2 transports the floating plate 5 that has separated from the limiting pillar 6 at the bottom out of the floating plate stacking bin 4, and then drops it onto the water surface through the delivery conveyor belt 3; The height of the discharge port is greater than the thickness of the floating plate 5 so as to ensure that the floating plate 5 can be normally transported out of the floating plate stack 4.

[0045] An inclined roller guide frame 10 is provided on the front end of the delivery conveyor belt 3 and the mounting frame 1 .

When the water floating board 5 is transported to the delivery conveyor belt 3, the discharging conveyor belt 2 stops working, and the delivery conveyor belt 3 continues to transport the water floating board 5 forward. After the cable 11 between the front water floating board 5 and the rear water floating board 5 is laid out, the discharging conveyor starting belt transports the next water floating board 5 out of the floating board stacking bin 4, and the front water floating board 5 continues to be transported by the delivery conveyor belt 3 and falls onto the sea surface after passing through the roller guide frame 10 (several water floating boards 5 fall onto the sea surface through the cooperation of the discharging conveyor belt 2, the delivery conveyor belt 3 and the staff, and the cables on the side are paid out through the cable drum); After that, the floating plates 5 are spread out, the winch 9 reels in the cable 11, and the staff controls the floating plates 5 on the side close to the raft platform 12. The winch 9 brings the adjacent floating plates 5 close to each other by reeling in the cable 11 until several floating plates 5 are close to each other (manual arrangement is required during this period). At this time, the electromagnets 509 of the adjacent floating plates 5 enter the corresponding mounting grooves 507.

After several floating plates 5 are spread out and connected, the expansion platform 13 is dragged to the first floating platform on the water, and the expansion platform 13 is adsorbed on the electromagnets 509 on the side of the first floating plate 5. When the extended floating platform is stored, the power cable is cut off, the winch 9 pays out the line, and the cable 11 is released to the initial length. The staff drags the floating board 5 close to the raft platform 12 ashore, pulls the cable 11, shortens the length of the cable 11 between the floating board 5 and the winch 9, and then transports the floating board 5 back to the floating board stacking bin 4 through the conveying mechanism. Start the limit electromagnet 7, lift the floating plate 5, pass the metal sleeve 503 through the limit column 6 and adsorb it on the limit electromagnet 7, then drag the next floating plate 5 in turn, pull the cable 11, shorten the length of the cable 11 between the floating plate 5 and the winch 9, and similarly lift the floating plate 5 to pass the metal sleeve 503 through the limit column 6 to adsorb the bottom of the metal sleeve 503 of the floating plate 5 that is already in place above. Then adjust the spacing between the cables 11 between adjacent floating plates 5 in turn to complete the storage of several floating plates 5 (during this period, the cables are stored through the cable reel).
