Description

A transfer device for offshore photovoltaic platforms Technical Field

[0001] This invention relates to the field of offshore photovoltaic platform technology, specifically to an offshore photovoltaic platform transfer device. Background Technology

[0002] Offshore photovoltaic (PV) platforms refer to PV power plant facilities used on the sea surface. They represent a new type of photovoltaic power generation. Due to the relatively open and unobstructed marine environment, and the ability to fully utilize the reflected light from water, offshore PV platforms generate significantly more electricity than onshore PV power plants. It is estimated that offshore PV can increase power generation by 5% to 10% compared to onshore PV.

[0003] Existing offshore photovoltaic platforms have certain shortcomings in the transportation process: When transporting existing offshore photovoltaic platforms, they are generally lifted directly onto the ship's deck by a crane and fixed by anchor cables. However, this method requires high precision in the operation of the crane during actual operation. After the platform is placed on the ship's deck, it is inconvenient to make fine adjustments to its position, which can easily cause collision damage to the ship and the platform. Based on the shortcomings of existing technology, this invention designs an offshore photovoltaic platform transportation device. Summary of the Invention

[0004] This invention provides a marine photovoltaic platform transfer device, which has the advantage that the platform does not directly contact the ship's deck during transfer, thus avoiding collision damage between the platform and the ship's deck, and solves the problems mentioned in the background art.

[0005] This invention provides the following technical solution: a transfer device for an offshore photovoltaic platform, comprising a transfer frame, with fixed structures fixedly installed on both sides of the top of the transfer frame; two fixed structures comprising trapezoidal frames, two sets of support plates and limiting grooves, the two trapezoidal frames being welded to the transfer frame, reinforcing rods being welded to the bottom of the two trapezoidal frames, lifting lugs being fixedly installed on both sides of the top of the two trapezoidal frames, fixed groove plates being welded to both sides of the two trapezoidal frames, two sets of support plates being disposed at both ends of the two trapezoidal frames, bidirectional lead screws being rotatably installed inside the two support plates, a throttle handle being fixedly installed at one end of the two bidirectional lead screws, first threaded blocks being threaded onto the outer surface of the two bidirectional lead screws, fastening rings being fixedly installed on one side of the two first threaded blocks, two limiting grooves being formed between the two support plates, and sliding blocks being fixedly installed at the bottom of the two first threaded blocks, with the bottoms of the two sliding blocks being slidably connected to the limiting grooves.

[0006] As a preferred embodiment of the present invention, the interior of the transfer frame is provided with a construction fence, and six side support rods are fixedly installed on the inner wall of the transfer frame.

[0007] As a preferred embodiment of the present invention, the transfer frame is provided with four reinforcing structures inside, and the four reinforcing structures include hinge rods and scale grooves.

[0008] As a preferred embodiment of the present invention, the four hinged rods are hingedly connected to the transfer frame, and friction pads are fixedly installed at the bottom of the four hinged rods.

[0009] As a preferred embodiment of the present invention, four scale slots are formed on the top of the transfer frame, and connecting rods are fixedly installed on the top of the four hinge rods, and the four connecting rods are rotatably connected to the transfer frame.

[0010] As a preferred embodiment of the present invention, a handwheel is fixedly installed on the top of the four connecting rods, and an arrow is provided on one side of the outer surface of the four handwheels.

[0011] As a preferred embodiment of the present invention, the outer surface of the transfer frame is provided with four fine-tuning structures, the four fine-tuning structures including mounting frames.

[0012] As a preferred embodiment of the present invention, four mounting brackets are mounted around the transfer frame, wherein two of the mounting brackets are fixedly mounted on one side with a fixing rod, and a synchronous motor is fixedly mounted inside the two fixing rods, and threaded rods are threaded inside the four mounting brackets.

[0013] In a preferred embodiment of the present invention, two of the threaded rods are fixedly connected to the output shafts of two synchronous motors, and the outer surfaces of the four threaded rods are threaded with second threaded blocks. The four second threaded blocks are in contact with the inner wall of the transfer frame, and rotating rods are rotatably installed inside the four second threaded blocks. Adjusting wheels are fixedly installed on both sides of the four rotating rods.

[0014] As a preferred embodiment of the present invention, pulleys are fixedly installed on the outer surfaces of the four threaded rods, and a synchronous belt is sleeved inside each pair of pulleys.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This offshore photovoltaic platform transfer device, through a fixed structure, fixes the offshore photovoltaic platform to the device by erecting the device on the ship's deck and then inserting the four pins of the photovoltaic platform into four fixed slots for initial fixation. Then, the four handles are rotated to rotate the bidirectional screw. Since the sliding block is limited inside the limiting slot, the two first threaded blocks can move horizontally inward on the outer surface of the bidirectional screw at the same time. This allows the two fastening rings to clamp and fix the pins of the offshore photovoltaic platform, thereby fixing the platform and preventing it from contacting the ship's deck during transfer, thus avoiding collision damage to the ship's deck.

[0017] 2. This offshore photovoltaic platform transfer device, through a reinforced structure, when the transfer frame is erected on the ship deck, by placing the transfer frame on the top of the deck, according to the length of the hull, by turning the handwheel and pointing the arrow to the scale groove, the hinge rod is folded at a certain angle, thereby allowing it to abut against the four corners of the ship deck, and the friction between the friction pads below and the deck is used to improve the stability of the transfer frame on the deck.

[0018] 3. This offshore photovoltaic platform transfer device, through a fine-tuning structure, allows for adjustments to the position of the transfer frame when it is erected on the ship's deck. By simultaneously activating two synchronous motors and connecting them with synchronous belts, the two output shafts drive four threaded rods to rotate. Due to the limiting mechanism of the transfer frame, four second threaded blocks move downwards on the outer surface of the threaded rods, thereby allowing the adjusting wheel to contact the deck and slightly lift the transfer frame upwards. Subsequently, workers can adjust the position of the transfer frame by pushing it, thus enabling more precise positioning when fixing the platform. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please refer to Figures 1-7. A transfer device for an offshore photovoltaic platform includes a transfer frame 1. Two fixing structures 2 are fixedly installed on the top two sides of the transfer frame 1. Each fixing structure 2 includes a trapezoidal frame 21, two sets of support plates 25, and limiting grooves 26. The two trapezoidal frames 21 are welded to the transfer frame 1. Reinforcing rods 22 are welded to the bottom of the two trapezoidal frames 21. Lifting lugs 23 are fixedly installed on the top two sides of the two trapezoidal frames 21. Fixing groove plates 24 are welded to the sides of the two trapezoidal frames 21. Two sets of support plates... 25 is set at both ends of the two trapezoidal frames 21. Two bidirectional lead screws 27 are rotatably installed inside the two support plates 25. A handle 210 is fixedly installed at one end of the two bidirectional lead screws 27. First threaded blocks 28 are threaded on the outer surface of the two bidirectional lead screws 27. A fastening ring 211 is fixedly installed on one side of the two first threaded blocks 28. Two limiting grooves 26 are opened between the two support plates 25. Sliding blocks 29 are fixedly installed at the bottom of the two first threaded blocks 28. The bottom of the two sliding blocks 29 is slidably connected to the limiting grooves 26.

[0029] Please refer to Figure 1-2. The interior of the transfer frame 1 is equipped with a construction fence 5, and six side support rods 6 are fixedly installed on the inner wall of the transfer frame 1.

[0030] The construction fence 5 facilitates workers' work on the transfer frame 1. The side support rods 6 make the device more stable.

[0031] Please refer to Figures 3-4. The transfer frame 1 has four reinforcing structures 3 internally, each including a hinge rod 31 and a graduated groove 36. The four hinge rods 31 are hinged to the transfer frame 1, and friction pads 32 are fixedly installed at the bottom of each hinge rod 31. Four graduated grooves 36 are located at the top of the transfer frame 1, and connecting rods 33 are fixedly installed at the top of each hinge rod 31, rotatably connecting to the transfer frame 1. Handwheels 34 are fixedly installed at the top of each connecting rod 33, and arrows 35 are provided on one side of the outer surface of each handwheel 34.

[0032] When the transfer frame 1 is installed on the ship deck, by placing the transfer frame 1 on the top of the deck, and according to the length of the ship, by turning the handwheel 34, the arrow 35 points to the scale groove 36, so that the hinge rod 31 can be folded at a certain angle, thereby making it abut against the four corners of the ship deck. The friction between the friction pad 32 below and the deck improves the stability of the transfer frame 1 on the deck.

[0033] Please refer to Figures 6-7. The outer surface of the transfer frame 1 is provided with four fine-tuning structures 4, each including a mounting bracket 41. The four mounting brackets 41 are mounted around the transfer frame 1. Two mounting brackets 41 have fixed rods 42 fixedly mounted on one side, and synchronous motors 43 are fixedly mounted inside the two fixed rods 42. Threaded rods 44 are threadedly mounted inside the four mounting brackets 41. Two threaded rods 44 are fixedly connected to the output shafts of the two synchronous motors 43. Second threaded blocks 45 are threadedly mounted on the outer surface of the four threaded rods 44. The four second threaded blocks 45 fit against the inner wall of the transfer frame 1. Rotating rods 46 are rotatably mounted inside the four second threaded blocks 45. Adjusting wheels 47 are fixedly mounted on both sides of the four rotating rods 46. Pulleys 48 are fixedly mounted on the outer surface of the four threaded rods 44, and a synchronous belt 49 is sleeved inside every two pulleys 48.

[0034] When the position of the transfer frame 1 needs to be adjusted after it is erected on the ship deck, two synchronous motors 43 are started simultaneously. Due to the connection of the synchronous belt 49, the two output shafts drive the four threaded rods 44 to rotate. Due to the limit of the transfer frame 1, the four second threaded blocks 45 can move downward on the outer surface of the threaded rods 44. This allows the adjusting wheel 47 to contact the deck and slightly lift the transfer frame 1 upward. Then, the staff can adjust the position of the transfer frame 1 by pushing it, which can make the position more accurate when fixing the platform.

[0035] Working principle: When a marine photovoltaic platform transfer device is used, the transfer frame 1 is first erected on the top of the ship's deck. Then, by simultaneously starting two synchronous motors 43, the two output shafts drive four threaded rods 44 to rotate due to the connection of the synchronous belt 49. Due to the limiting of the transfer frame 1, the four second threaded blocks 45 move downward on the outer surface of the threaded rods 44, thereby allowing the adjusting wheel 47 to contact the deck and slightly lift the transfer frame 1 upward. Then, the operator can adjust the position of the transfer frame 1 by pushing it, which allows for more precise positioning when fixing the platform. Then, according to the length of the hull, the position can be adjusted by turning the handwheel 34, indicated by arrow 35. Pointing to the scale groove 36, the hinge rod 31 is folded at a certain angle, which allows it to abut against the four corners of the ship's deck. The friction between the friction pad 32 below and the deck increases the stability of the transfer frame 1 on the deck. Finally, the offshore photovoltaic platform is lifted by a crane, and then the four pins of the photovoltaic platform are inserted into the four fixing slot plates 24 for initial fixation. Then, the four throttles 210 are turned to rotate the bidirectional lead screw 27. Since the sliding block 29 is limited inside the limiting groove 26, the two first threaded blocks 28 can move horizontally inward on the outer surface of the bidirectional lead screw 27 at the same time, so that the two fastening rings 211 can clamp and fix the pins of the offshore photovoltaic platform.
