Description

Technical Field

[0001] The invention relates to the technical field of marine solar power generation, in particular to a marine solar power station and an operating method thereof. Background Art

[0002] With the development of economy and the progress of society, people have put forward higher and higher requirements for new energy. Finding new energy has become an urgent issue facing mankind. The existing sources of electric energy mainly include thermal power, hydropower and nuclear power, all of which have the following disadvantages.

[0003] 1. Thermal power generation requires the burning of fossil fuels such as coal and oil, but fossil energy reserves are limited. The more they are burned, the less they are, and they are facing the risk of depletion. In addition, combustion will emit carbon dioxide and sulfur oxides, leading to the greenhouse effect and acid rain, worsening the earth's environment.

[0004] 2. Hydropower requires flooding a large amount of land, causing damage to the ecological environment and the risk of reservoir collapse. Furthermore, water resources are limited and are greatly affected by seasonal changes.

[0006] The main characteristics of new energy are that it is abundant, inexhaustible, safe, environmentally friendly, and will not threaten the human environment. From history to today, the main new energy sources are: ① Solar energy and fuel cells. ② Wind power generation can be used as an auxiliary new energy source.

[0007] Among them, the most ideal new energy source is solar energy. As an external energy source, the solar energy that shines on the earth is very huge. According to reports, the solar energy that shines on the earth for about 40 minutes can provide energy consumption for the entire world's human population for a year. It is a truly inexhaustible energy source. Solar power generation is absolutely clean and will not produce any pollution.

[0008] In summary, solar power generation is internationally recognized as the most ideal new energy source.

[0009] The construction of solar power stations requires a large area for solar panels to be arranged. Large-scale solar panels have been installed in deserts and barren mountains on land, and photovoltaic power stations have also been built at sea. Ships are small, medium, or large marine and water equipment that can move. It is absolutely impossible to use cables to transmit solar or other clean energy on land and load them on ships.

[0010] However, compared with land-based equipment such as cars and trains, ships, whether small, medium or large, have huge main dimensions and a huge upper surface area exposed to the sun. How to use this favorable feature to realize the application of solar power generation on ships is in line with the current historical trend of new energy iteration.

[0011] Although there are currently some ship types that carry solar panels on the top of ro-ro ships, they are only suitable for ships with fixed roofs. As one of the types of ships, cargo ships must set up cargo holds to load cargo, so cargo loading and unloading is required. At this time, it is impossible to set up a fixed structure roof and carry fixed solar panels. At this time, it is necessary to consider the use of solar energy above the cargo hold to receive sunlight. It is necessary to design a hatch cover that can be removed when loading and unloading cargo, and a device that can quickly install solar photovoltaic panels outside of loading and unloading. In addition, another important factor that cargo ships need to consider is the load capacity. The load capacity is an important indicator for shipping companies to achieve sustainable development. If solar panels are installed, the weight of the ship will be increased to a certain extent, thereby reducing the ship's load capacity. Therefore, it is also necessary to solve the contradiction between lightweight devices and increased load capacity. Summary of the invention

By adopting the power station with the above structure, when the ship needs to load or unload cargo, the lightweight hatch cover is towed to within the length range of a hatch cover at any end of the front or rear end of the ship, so that the cargo hold hatch is basically fully opened, and the cranes on the shore or other loading and unloading methods can realize the lifting operation of the ship's cargo for loading and unloading; when the ship's cargo is loaded and unloaded, a group of multiple hatch covers overlapping within the length range of a hatch cover are towed until they reach the hatch position to be covered, and the hatch covers are distributed over the entire cargo hatch; the solar panels covered on the hatch cover can directly see the sunlight and connect various parts of the power generation system, and clean solar electricity can supply power to all electrical equipment.

[0058] In this embodiment, a total of 6 lightweight hatch covers are provided, namely the first lightweight hatch cover 1, the second lightweight hatch cover 2, the third lightweight hatch cover 3, the fourth lightweight hatch cover 4, the fifth lightweight hatch cover 5, and the sixth lightweight hatch cover 6, among which the first lightweight hatch cover 1 is located at the innermost layer.

Through the above-mentioned size structure, it is ensured that multiple sections of lightweight hatch covers can be arranged in an overlapping manner in order to facilitate their storage, thereby calculating the occupied area of ​​a single lightweight hatch cover to increase the coverage area.

[0063] Furthermore, the width is based on the width of the ship's cargo hold + the thickness of the lightweight hatch cover on both sides + the gap between the hatch covers that need to be overlapped + the distance from the outermost railing + the total width and thickness of all hatch cover side walls and supporting columns = maximum width.

[0064] Furthermore, the lightweight hatch cover includes a herringbone-shaped strong transverse beam arch 26, which has a slope of 5-8%; hatch cover support columns 23 are fixedly installed at both ends of the herringbone-shaped strong transverse beam arch 26 and located in the same plane, and a windshield plate is fixed on the outside of the hatch cover support column 23.
