Description

Technical Field

[0001] This invention relates to the field of offshore photovoltaic operation platforms, and more particularly to an offshore photovoltaic engineering operation platform. Background Technology

[0002] As a key infrastructure for offshore photovoltaic (PV) construction, the development of offshore PV engineering operation platforms has gone through several stages. Early offshore PV operation platforms were relatively simple in design, mostly modified from traditional offshore floating structures. These platforms mainly served to carry construction personnel and basic construction equipment, providing a relatively stable workplace for the installation and commissioning of offshore PV modules. With the continuous advancement of offshore PV technology, the functions of operation platforms have gradually diversified, beginning to possess material storage, transportation, and a certain degree of automated operation capabilities.

[0003] Currently, existing offshore photovoltaic (PV) engineering operation platforms have many shortcomings in practical applications. First, regarding platform scalability, most existing platforms are fixed structures, making it difficult to flexibly adjust and expand them according to different construction needs. When encountering large-scale offshore PV projects, existing platforms may not be able to provide sufficient operating area and storage space, leading to chaotic material stacking during construction and affecting construction efficiency. Moreover, if adjustments to the platform's operating range are needed during construction, it often requires a significant amount of time and resources for reconstruction or modification, severely impacting project progress. Summary of the Invention

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

[0005] This invention is achieved through the following measures: A marine photovoltaic engineering operation platform includes a raft platform, on which several extended floating platforms in different directions are provided. The extended floating platform includes an installation frame on the raft platform, a conveying mechanism is provided on the installation frame, and a float stack is provided above the conveying mechanism and on the installation frame, with several floating boards stacked in the float stack. The first floating platform is connected to an extension platform on its side.

[0006] The raft platform serves as a carrying platform, on which several extended floating platforms in different directions are mounted to facilitate operations in different directions. At the same time, other working equipment is also mounted on the raft platform. The load-bearing capacity of the raft platform is greater than the total weight of the extended floating platforms, the workers, and the mounted equipment. The raft platform is equipped with protective railings around its perimeter.

[0007] The invention also has the following specific features: The floating plate has a pair of through-holes along its length. A winch is installed on the top of the floating plate stack. The cable end of the winch passes through several of the adjustment holes of the floating plate and is fixedly installed on the side of the first floating plate. The bottom of the floating platform is provided with a pair of rectangular support blocks, and the cables between adjacent stacked floating platforms are located between the rectangular support blocks on both sides.

[0008] By setting the rectangular support block, space can be provided between adjacent floating boards when they are stacked, which makes it easier for staff to organize and place cables. Preferably, the winch cable is a flexible rope.

[0009] A limiting column is provided on the inner side of the top of the floating plate stack. A limiting electromagnet is provided near the top of the limiting column. The distance between the bottom of the limiting 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 located around the limiting column. The top of the metal sleeve is higher than the top surface of the floating plate, and the bottom of the metal sleeve is higher than the bottom surface of the rectangular support block.

[0010] The distance between the bottom of the limiting column and the conveying mechanism ensures that the floating plate can be normally conveyed out of the floating plate stack. Meanwhile, the positions of the upper and lower ends of the metal sleeve are set to ensure that when adjacent floating boards are stacked, the metal sleeves of the upper and lower floating boards can be closed, thereby forming a magnetic attraction limit on several floating boards through the limiting electromagnet. Several of the aforementioned floating boards are provided with cables on their sides, and each of the left and right sides of the floating board is provided with a mounting side plate. Each of the two mounting side plates is provided with a metal plate and an electromagnet at a corresponding position.

[0011] The cable is installed on the side of the floating board using fasteners. The electromagnet is powered by the cable. The cable length ensures that several floating boards can be properly deployed and stacked. During the deployment and stacking of the floating boards, staff assist in sorting the cables to prevent them from getting tangled.

[0012] The mounting side plate has a pair of U-shaped grooves corresponding to the position of the adjustment through hole. The pair of U-shaped grooves includes a first U-shaped groove and a second U-shaped groove. The U-shaped grooves have through holes corresponding to the adjustment through hole. The winch cable passes sequentially through the through hole on one side, the adjustment through hole, and the through hole on the other side; The mounting side plate has several mounting grooves on its surface, and the metal plate is placed in the mounting grooves. The position and shape of the mounting grooves are matched with the electromagnet.

[0013] The electromagnet can be inserted into the mounting groove and attract 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 mounted on the mounting frame, and the floating plate stack is mounted above the discharge conveyor belt and on the mounting frame. The floating plate stack includes a left side plate, a right side plate, and a top plate disposed on the mounting frame. A discharge port is disposed between the right side plate and the conveying mechanism, and the height of the discharge port is greater than the thickness of the floating plate.

[0015] The discharge conveyor belt transports the bottommost floating plate, which is detached from the limiting column, out of the floating plate stack and then onto the water surface via the delivery conveyor belt. The height of the discharge port is greater than the thickness of the floating plate, thereby ensuring that the floating plate can normally transport the floating plate stack.

[0016] The front end of the delivery conveyor belt and the mounting frame are provided with inclined roller guide frames.

[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] The expansion platform is equipped with a metal mounting plate on its side.

[0019] When the extended floating platform is laid, the first step is to deploy the floating pontoons. The limiting electromagnets are closed, and the discharge conveyor belt transports the bottommost floating pontoon, which has detached from the limiting column, out of the pontoon stack. After the floating pontoon is transported to the deployment conveyor belt, the discharge conveyor belt stops working, and the deployment conveyor belt continues to transport the floating pontoons forward. After the cables between the front and rear floating pontoons are laid out, the discharge conveyor belt starts to transport the next floating pontoon out of the pontoon stack. The front floating pontoons are continuously transported by the deployment conveyor belt, pass through the roller guide frame, and fall onto the sea surface (several floating pontoons fall onto the sea surface through the coordinated efforts of the discharge conveyor belt, the deployment conveyor belt, and the workers, during which the side cables are laid out through the cable reel). Next, the floating platforms are deployed. The winch winds up the cable, and the workers control the floating platform on the side closest to the raft platform. The winch winds up the cable to bring adjacent floating platforms closer together until several floating platforms are pressed together (during which time manual adjustment is performed). At this time, the electromagnets of adjacent floating platforms enter the corresponding installation grooves. Then the cable is energized, and adjacent floating platforms form a magnetic connection with the metal plate through the electromagnets (the raft platform is equipped with matching electromagnets on its side, and the floating platforms on the side closest to the raft platform are attracted to the electromagnets on the side of the raft platform). After several floating platforms are deployed and connected, the extension platform is dragged to the first floating platform and attracted to the electromagnet on the side of the first floating platform. When the extended floating platform is being stored, the power to the cable is cut off, the winch releases the cable to its initial length, and workers drag the floating platform near the raft platform ashore, pulling the cable to shorten the cable length between the floating platform and the winch. The floating platform is then transported back to the floating platform stack via a conveyor mechanism. Activate the limiting electromagnet, raise the floating board, and let the metal sleeve pass through the limiting post to be attracted to the limiting electromagnet. Then, drag the next floating board in sequence, pull the cable, and shorten the length of the cable between the floating board and the winch. Similarly, raise the floating board and let the metal sleeve pass through the limiting post to be attracted to the bottom of the metal sleeve of the floating board that is already in place above. Then, adjust the spacing of the cables between adjacent floating boards in sequence to complete the storage of several floating boards (during which the cables are stored through the cable reel).

[0020] The beneficial effects of this invention are as follows: By combining a raft platform with several extended floating platform structures, the working area can be flexibly adjusted according to different construction needs, improving the versatility and adaptability of the platform, better meeting the construction requirements of large-scale offshore photovoltaic projects, and improving construction efficiency and quality.

Extension platform. Detailed Implementation

[0033] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0034] See Figure 1-11A marine photovoltaic engineering operation platform includes a raft platform 12, on which several extended floating platforms in different directions are provided. The extended floating platforms include an installation frame 1 on the raft platform 12, a conveying mechanism on the installation frame 1, a float stack 4 above the conveying mechanism and on the installation frame 1, and several floating boards 5 are stacked in the float stack 4. The first floating platform 5 is connected to an extension platform 13 on its side.

[0035] The raft platform 12 serves as a carrying platform, on which several extended floating platforms in different directions are mounted to facilitate operations in different directions. At the same time, the raft platform 12 is also equipped with other working equipment. The load-bearing capacity of the raft platform 12 is greater than the total weight of the extended floating platforms, the workers, and the equipment. The raft platform 12 is surrounded by guardrails.

[0036] The floating plate 5 has a pair of through-holes along its length. The top of the floating plate stack 4 is equipped with a winch 9. The end of the cable 11 of the winch 9 passes through several through-holes of the floating plate 5 and is fixedly installed on the side of the first floating plate 5. The bottom of the floating platform 5 is provided with a pair of rectangular support blocks 501, and the cable 11 between the adjacent stacked floating platforms 5 is between the rectangular support blocks 501 on both sides.

[0037] By setting rectangular support blocks 501, space can be provided between adjacent floating boards 5 when they are stacked, which makes it easier for staff to sort and place 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. A limit electromagnet 7 is provided near the top of the limit column 6. The distance between the bottom of the limit column 6 and the conveying mechanism is greater than the thickness of the floating plate 5. A metal sleeve 503 is provided at the center of the floating plate 5, and the metal sleeve 503 is located around the limiting column 6. The top of the metal sleeve 503 is higher than the top surface of the floating plate 5, and the bottom of the metal sleeve 503 is higher than the bottom surface of the rectangular support block 501.

[0039] The distance between the bottom 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. Meanwhile, the positions of the upper and lower ends of the metal sleeve 503 are set to ensure that when adjacent floating boards 5 are stacked, the metal sleeve 503 of the upper and lower floating boards 5 can be closed, thereby forming a magnetic attraction limit on several aquatic floating boards through the limiting electromagnet 7. Several floating boards 5 are equipped with cables on their sides. The floating boards 5 are equipped with mounting side plates 502 on both the left and right sides. The mounting side plates 502 on both sides are respectively equipped with metal plates 508 and electromagnets 509.

[0040] The cable is installed on the side of the floating board 5 through the mounting fastener. The electromagnet 509 is powered by the cable. At the same time, the length of the cable ensures that several floating boards 5 can be properly deployed and stacked. During the deployment and stacking of the floating boards 5, the staff assists in sorting the cables and wires 11 to prevent them from getting tangled.

[0041] The mounting side plate 502 is provided with a pair of U-shaped grooves 504 at the position corresponding to the adjustment through hole. The pair of U-shaped grooves 504 includes a first U-shaped groove and a second U-shaped groove. A through hole 506 corresponding to the adjustment through hole is provided on the U-shaped groove 504. The cable 11 of the winch 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; The mounting side plate 502 has several mounting grooves 507 on its surface, and the metal plate 508 is placed in the mounting grooves 507. The position and shape of the mounting grooves 507 are matched with the electromagnet 509.

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

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

[0044] The discharge conveyor belt 2 transports the bottommost floating plate 5, which is detached from the limit column 6, out of the floating plate stack 4, and then it falls onto the water surface via the delivery conveyor belt 3. The height of the discharge port is greater than the thickness of the floating plate 5, thus ensuring that the floating plate 5 can normally transport the floating plate stack 4.

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

[0046] Inside the first and second U-shaped grooves, and on the upper and lower sides of the cable 11 of the winch 9, cable guide wheels 505 are provided.

[0047] The side of the expansion platform 13 is equipped with a metal mounting plate.

[0048] When the extended floating platform is laid, the first step is to deploy the floating pontoons 5. The limiting electromagnet 7 is closed, and the discharge conveyor belt 2 transports the bottom floating pontoons 5, which are detached from the limiting column 6, out of the pontoon stack 4. After the floating pontoons 5 are transported to the deployment conveyor belt 3, the discharge conveyor belt 2 stops working, and the deployment conveyor belt 3 continues to transport the floating pontoons 5 forward. After the cable 11 between the front floating pontoons 5 and the rear floating pontoons 5 is laid out, the discharge conveyor belt starts to transport the next floating pontoons 5 out of the pontoon stack 4. The front floating pontoons 5 are continuously transported by the deployment conveyor belt 3, pass through the roller guide frame 10, and fall into the sea (several floating pontoons 5 fall into the sea through the coordinated efforts of the discharge conveyor belt 2, the deployment conveyor belt 3, and the workers. During this process, the side cables are laid out through the cable reel). Next, the floating platform 5 is laid out. The winch 9 winds up the cable 11. The staff controls the floating platform 5 on the side closest to the raft platform 12. The winch 9 winds up the cable 11 to bring the adjacent floating platforms 5 closer to each other until several floating platforms 5 are pressed together (during which manual adjustment is carried out). At this time, the electromagnets 509 of the adjacent floating platforms 5 enter the corresponding installation grooves 507. Then the cable is energized, and the adjacent floating platforms 5 form a magnetic connection with the metal plate 508 through the electromagnets 509 (the raft platform 12 is equipped with matching electromagnets 509 on its side, and the floating platform 5 on the side closest to the raft platform 12 is attracted to the electromagnets 509 on the side of the raft platform 12). After several floating platforms 5 are laid out and connected, the extension platform 13 is dragged to the first floating platform and attracted to the electromagnets 509 on the side of the first floating platform 5. When the extended floating platform is being stored, the power to the cable is cut off, the winch 9 releases the cable, and the cable 11 is released to its initial length. Workers then tow the floating platform 5, which is close to the raft platform 12, ashore, and pull on the cable 11 to shorten the length of the cable 11 between the floating platform 5 and the winch 9. Afterward, the floating platform 5 is transported back to the floating platform stack 4 via a conveyor mechanism. Activate the limiting electromagnet 7, raise the floating board 5 so that the metal sleeve 503 passes through the limiting post 6 and is attracted to the limiting electromagnet 7. Then, drag the next floating board 5 in sequence, pull the cable 11, shorten the length of the cable 11 between the floating board 5 and the winch 9, and similarly raise the floating board 5 so that the metal sleeve 503 passes through the limiting post 6 and is attracted to the bottom of the metal sleeve 503 of the floating board 5 that is already in place above. Then, adjust the spacing of the cable 11 between adjacent floating boards 5 in sequence to complete the storage of several floating boards 5 (during which the cable is stored through the cable reel).
