Description

Technical Field

[0001] This utility model relates to the field of marine photovoltaic technology, specifically a marine photovoltaic operation and maintenance basket. Background Technology

[0002] Compared with conventional onshore photovoltaic power generation, offshore photovoltaic power generation has advantages such as open sea surface without obstructions, abundant sunshine, no occupation of scarce land resources, easy integration with other marine industries, and proximity to power load centers, and has developed rapidly in recent years.

[0003] Currently, the commonly used operation and maintenance methods at sea mainly include manual climbing operation and maintenance, and lifting platform operation and maintenance. These operation and maintenance methods have the following problems when used for the operation and maintenance of offshore photovoltaic modules: (1) The elevation of offshore photovoltaic modules is relatively high, and manual climbing operation and maintenance is very dangerous. In addition, it is difficult and inefficient to manually move photovoltaic modules; (2) The waves at sea are large. When the ship rocks slightly, the swaying amplitude of the platform lifted to a high position cannot meet the operation requirements. Therefore, small vessels cannot meet the stability requirements of the lifting platform, while large vessels cannot enter the lower part of the offshore photovoltaic support platform to carry out lifting operations. To address these issues, we propose an offshore photovoltaic operation and maintenance basket to solve the above problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a marine photovoltaic operation and maintenance gantry, which solves the problems mentioned in the background.

[0005] This utility model provides the following technical solution: a marine photovoltaic operation and maintenance gantry, applied to marine photovoltaic operation and maintenance scenarios, comprising: a gantry body, the gantry body being a frame structure composed of beams, columns, bottom and side panels, and a protective door on the side of the gantry body; a slot, the slot being located inside the gantry body, the gantry body being secured to a photovoltaic panel via the slot; and a lifting mechanism, the lifting mechanism comprising a motor, a sling and a battery, the motor being located at the top of the column of the gantry body, the gantry body being able to be suspended from the marine photovoltaic support using the sling.

[0006] Preferably, the slots can be symmetrically arranged in two sets, one set of slots is used to attach new photovoltaic panels and the other set is used to attach old photovoltaic panels. The two sets of slots can fix new and old photovoltaic panels at the same time, eliminating the need to frequently change the clamps or adjust the equipment, thus reducing installation steps and time.

[0007] Preferably, the output shaft of the motor is equipped with a drum, which is fixedly connected to the sling. Multiple sets of motors and slings are set up in a one-to-one correspondence, so the length of each sling can be adjusted individually, thereby accurately controlling the force distribution at each corner or suspension point of the suspended basket to meet the needs of actual applications.

[0008] Preferably, the battery is installed on the bottom plate of the suspended platform body. The battery is electrically connected to the motor and is used to power the motor. Installing the battery on the bottom plate of the suspended platform body makes full use of the idle space at the bottom of the suspended platform and avoids occupying key areas such as the operating platform or suspension mechanism, making the overall structure more compact.

[0009] Compared with the prior art, the present invention has the following beneficial effects: This offshore photovoltaic (PV) maintenance pod completely eliminates the impact of ship swaying by directly fixing the pod to the main structure of the offshore PV support, fundamentally solving the risks of large swaying and falling from heights associated with conventional ship-mounted pods. Combined with its own motor system and multi-sling independent control technology, it can achieve precise high-altitude positioning with the assistance of only a small maintenance vessel, allowing maintenance personnel to replace multiple PV modules without leaving the pod. The enclosed protective structure further ensures operational safety. Attached Figure Description

[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figure 1-5A type of offshore photovoltaic (PV) operation and maintenance gantry, applied to offshore PV operation and maintenance scenarios, includes: a gantry body 1, which is a frame structure composed of beams, columns and bottom sealing plates, and a protective door 2 on the side of the gantry body 1. The frame structure composed of beams, columns and bottom sealing plates provides high-strength support and can withstand the wind and wave loads in the marine environment, ensuring the safety of operation and maintenance personnel and equipment. The protective door 2 is designed to prevent personnel from falling accidentally, and the bottom sealing plate reduces the entry of marine salt spray and moisture into the interior, protecting electrical components.

[0014] The slot 5 is located inside the suspended platform body 1, and the suspended platform body 1 is connected to the photovoltaic panel 6 through the slot 5. Two sets of slots 5 can be symmetrically arranged. One set of slots 5 is used to connect new photovoltaic panels 6, and the other set is used to connect old photovoltaic panels 6, so as to realize the quick replacement of new and old panels, reduce downtime, and make full use of the internal space of the suspended platform body 1. It avoids the risk of damage caused by mixing new and old panels and improves the safety of operation.

[0015] The lifting mechanism includes a motor 3, slings 4, and a battery 7. The motor 3 is located on the top of the column of the basket body 1. The basket body 1 can be suspended from the offshore photovoltaic support using the slings 4. The output shaft of the motor 3 is equipped with a drum, which is fixedly connected to the slings 4. The motor 3 adjusts the independent raising and lowering of the four slings 4 through the drum. The battery 7 is installed on the bottom plate of the basket body 1 and is electrically connected to the motor 3. The battery 7 is used to power the motor 3, eliminating dependence on the ship's power supply. The built-in battery 7 powers the motor 3, ensuring continuous operation capability.

[0016] Furthermore, the corrosion-resistant design and independent adjustment function of each component enable it to withstand challenges such as wind, waves, and salt spray, ensuring long-term stable operation. The working principle is as follows: When replacing offshore photovoltaic modules, the four hoisting straps 4 are first fixed to the offshore photovoltaic support structure using a small vessel's crane. Then, the new photovoltaic panels 6 to be installed are fixed inside the basket body 1 using slots 5. Considering that the old photovoltaic panels 6 also need to be temporarily fixed inside the basket body 1 after removal, at least two sets of slots 5 are provided: one set for fixing the new photovoltaic panels 6 to be installed, and one set for temporarily storing the removed old photovoltaic panels 6. After the photovoltaic panels 6 are fixed, maintenance personnel enter the basket body 1 and close the protective door 2. Then, the control system of the motor 3 is activated to control the raising and lowering of each hoisting strap 4, allowing the basket body 1 to rise smoothly to the required position. At an appropriate location below the replacement photovoltaic panel 6, the damaged photovoltaic panel 6 is removed using maintenance tools and fixed in the reserved slot 5. The new photovoltaic panel 6 is then installed. After replacing one component, the length of each sling 4 can be independently adjusted via motor 3, allowing the basket body 1 to make small-range horizontal movements or attitude adjustments within the space below the support, such as fine-tuning the height, horizontal position, or angle, to precisely align with the next photovoltaic panel 6 to be replaced. After installing all the new components carried by the basket body 1, the sling 4 is slowly lowered to the deck of the maintenance vessel via motor 3, completing the component replacement work in that area. The above operations are repeated to replace components in the remaining areas.

[0017] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
