Description

Technical Field

[0001] This invention relates to the field of offshore operation equipment technology, and in particular to a high-altitude operation vessel suitable for the construction and operation and maintenance of offshore photovoltaic projects. Background Technology

[0002] Offshore photovoltaic projects are typically located in shallow nearshore areas where tides are constant and water depths are unpredictable, making it impossible for large vessels to enter. Meanwhile, onshore equipment is often unusable due to its distance from the shore. Current technology often employs floating scaffolding platforms constructed by erecting scaffolding on buoys to meet the needs of working at heights.

[0003] However, this type of floating platform has significant drawbacks: it has poor stability and can only be used in calm conditions; it is inconvenient for workers to get on and off, resulting in low safety; and it cannot provide reliable safety belt attachment points for working at heights, posing extremely high safety risks.

[0004] Therefore, there is an urgent need for a specialized vessel that can provide a stable and safe operating platform for offshore photovoltaic projects. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a marine photovoltaic high-altitude operation vessel with good stability, high safety and flexible operation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A marine photovoltaic high-altitude operation vessel includes a main hull and a superstructure. The main hull is a catamaran structure, comprising a symmetrically arranged first and second hull, and a connecting bridge covering the upper deck of the hull and the connecting bridge. The first hull is divided into a forecastle, empty compartment, freshwater tank, empty compartment again, and oil storage tank from bow to stern; the second hull is also divided into a forecastle, empty compartment, freshwater tank, empty compartment again, and battery compartment from bow to stern. The superstructure is located on the deck and includes a generator, a lifting platform, an operating main engine, and a bridge, with these devices arranged sequentially along the central axis of the main hull from bow to stern.

Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. It should be noted that the following description is intended to enable those skilled in the art to clearly understand the present invention and is not intended to limit the scope of protection.

[0023] See Figures 1 to 5 This invention provides a vessel for high-altitude photovoltaic operations at sea, which includes a main hull 1 and a superstructure.

[0024] The main hull 1 adopts a steel catamaran structure, with an anti-corrosion coating on the outside. The main hull 1 includes a first compartment 1a and a second compartment 1b arranged symmetrically, which are rigidly connected by a connecting bridge 1c, and the hull covers the entire upper part. This symmetrical structure is the basis for the ship's excellent stability.

[0025] The first hull 1a is divided into a forecastle 11, an empty compartment 12, a freshwater tank 13, an empty compartment 12, and an oil tank 14, from bow to stern. The second hull 1b is also divided into a forecastle 11, an empty compartment 12, a freshwater tank 13, an empty compartment 12, and a battery compartment 15, from bow to stern. The freshwater tank 13 stores freshwater and is equipped with an electric submersible pump for hull cleaning; the oil tank 14 contains a fuel tank 16 to provide fuel, such as diesel, for the generator; the battery compartment 15 contains battery banks and a charging system to power all shipboard electrical equipment. The empty compartment 12 can be used to store materials and equipment needed during ship operation or work at height.

[0026] The superstructure is arranged on deck 1d, and the generator 2, lifting platform 3, main control unit 4, and bridge 5 are arranged sequentially from bow to stern along the ship's central axis. This layout helps optimize the ship's center of gravity distribution and further enhances stability.

[0027] For example, the generator 2 is a diesel generator, which is the main power source of the ship.

[0028] For example, the lifting platform 3 is the core working equipment, and the electric lift 31 at its bottom drives the upper working platform 32 to rise and fall. The working platform is surrounded by a closed fence 33 with a height of more than 1.2 meters, one side of which has a guardrail gate, providing a stable and safe working surface for working at height.

[0029] It is understood that the number and size of the lifting platforms 3 can be determined according to the actual on-site operational needs. During maintenance and other operations, only one electric lift 31 and one work platform 32 can be installed for a small number of personnel. When large-scale operations such as component installation are required, the hull size can be increased and multiple electric lifts 31 and multiple work platforms 32 can be installed to accommodate simultaneous work by a large number of personnel.

[0030] For example, the operating host 4 is electrically started, and can be powered by either the generator 2 or the storage battery. Ship operators can control the ship's lifting platform, electric submersible pumps in the freshwater tanks, and other equipment via the operating host. The operating host is also equipped with an automatic charging device, which automatically charges the storage battery via the generator during startup.

[0031] For example, the control console 5 is located behind the main control unit 4 and is used to control the external propulsion system 9 at the stern of the vessel. During operation, the vessel operators can control the external propulsion system 9 at the stern via the control console 5, enabling flexible vessel movement. The external propulsion system 9 is electric, powered by a generator 2 and a battery.

[0032] For example, the oil storage tank 14, the battery compartment 15 and the empty compartment 12 are all equipped with weatherproof covers 17 to effectively prevent seawater intrusion and ensure the safety of the compartment.

[0033] For example, the freshwater tank 13 is provided with an inlet cover 110, which serves as the inlet and outlet for cleaning and maintenance of the water tank during normal cleaning. Water can be pumped and stored directly through the inlet cover 110 during normal cleaning.

[0034] For example, a life-saving wardrobe 6 is provided below the operating host 4, and the life-saving wardrobe 6 is provided with life-saving equipment such as life rings, life jackets, and smoke signals.

[0035] For example, the main hull 1 is provided with a plurality of personnel seats 7, and storage boxes are provided under the personnel seats 7, which can be used to store construction tools and other items.

[0036] For example, to ensure operational safety, two mooring bollards 18 are installed on each side of the main hull 1. When the lifting platform 3 is raised for operation, the mooring bollards can be connected to the site piles with cables to fix the ship's position and ensure safe operation of the ship.

[0037] For example, the main hull 1 is provided with fixed handrails 19 on both sides and a railing with a height of not less than 1.2 meters at the stern.

[0038] For example, the main hull 1 is equipped with lighting lamps 8 at both the bow and stern, which are powered by generators 2 and batteries to meet the needs of emergency maintenance at night.

[0039] Therefore, the offshore photovoltaic high-altitude operation vessel provided by the embodiments of the present invention, through the combined design of a catamaran symmetrical structure and core equipment arranged along the central axis, directly lowers the vessel's center of gravity from a physical perspective, increases the restoring moment, and has inherent stability superior to traditional monohull vessels or floating platforms. Secondly, by setting up high-standard fences, mooring bollards, and dual power supply systems, it can provide a safer working environment for operators, effectively reducing the risks of falls from heights, vessel drift, and power failure. Furthermore, the lifting platform 3 can be equipped with multiple small hull designs, which can flexibly adapt to different operation scales, from maintenance by a few people to simultaneous construction by multiple people, and can freely move within narrow, shallow existing photovoltaic field areas, making it suitable for a wide range of applications.

[0040] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
