Description

Technical Field

[0001] The invention relates to a solar photovoltaic equipment arrangement structure of a car roll-on / roll-off ship, belonging to the technical field of ship solar photovoltaic arrangement. Background Art

[0002] With the continuous improvement of energy conservation and environmental protection requirements, the International Maritime Organization has also continuously put forward higher energy efficiency requirements for new ships and operating ships. Various methods that can promote energy conservation and emission reduction are being studied and practiced. The use of clean energy such as solar energy is a very effective method. Solar panels have a long service life and low maintenance costs, and have high environmental and economic value.

[0003] Ro-Ro ships, especially large ones, have natural advantages in using solar photovoltaic equipment for power generation: Ro-Ro ships have more decks, a higher overall depth, and a relatively shallow draft when sailing, so the outer hull area on both sides of the ship is very large. At the same time, there are fewer openings on the outer hull above the waterline, mainly for the side ramps, fuel filling stations, etc. The large outer plate area without openings on the upper part can be used to set up solar photovoltaic equipment such as solar panels or photovoltaic panels, which absorb a large amount of solar energy and convert it into electrical energy for the ship to use, achieve energy conservation and emission reduction, and reduce operating costs. At the same time, during the period of berthing or maintenance of the ship, solar photovoltaic equipment can provide an independent power supply, thereby enhancing the ship's self-sufficiency. In addition, the upper open deck of the car ship also has a large space area, which can be used to arrange distributed solar photovoltaic equipment for solar power generation.

[0004] In the existing traditional practice of car ro-ro ships, daily power supply and ship power are mainly provided by fuel such as fuel oil or LNG (which pollutes the environment and is costly). A few ships have a limited number of photovoltaic panels arranged on the upper open deck, such as Figure 1 As shown in FIG. 1 , no device for generating electricity is provided on the ship's side plate. Figure 2 and Figure 3 As shown, the panels are basically bare without any power generation equipment.

[0005] Disadvantages of existing technologies: The large-area space advantage of the side outer plate of a car ro-ro ship has not been effectively utilized; the utilization rate of clean new energy is not high, which is not conducive to energy conservation and emission reduction of ships, and the operating cost is relatively high. Summary of the invention

[0006] The technical problem to be solved by the present invention is to provide an additional clean energy supply for car ro-ro ships, achieve energy conservation and emission reduction, and reduce the purpose of operating costs. At present, the main power of car ro-ro ships is fuel oil or LNG and other energy sources. Very few ships are equipped with solar panels on the upper open decks, and the use of clean energy is very small, and the energy conservation and emission reduction efforts are insufficient. The present application arranges solar photovoltaic equipment (solar panels or photovoltaic panels) on the side outer plate of the car ro-ro ship to convert solar energy into electrical energy, and uses zero-carbon clean energy to provide electricity supply for the ship. The electrical energy can be stored or directly used by arranging large-capacity batteries for daily electricity use on board or even ship driving, thereby reducing the consumption of carbon-containing fuels, playing a greater positive role in energy conservation and emission reduction, and greatly reducing the operating costs of the ship.

[0007] The present invention specifically adopts the following technical solutions:

[0008] A solar photovoltaic equipment arrangement structure for a car roll-on / roll-off ship is provided, wherein a solar photovoltaic panel 5 covering at least one deck height is provided on the ship outer plate 1 above the main deck 4, wherein the solar photovoltaic panel 5 rotates at the height of one of the upper decks 3 and can be turned up or down by 80°-100° under the drive of a self-contained turning power mechanism, and the upper surface of the solar photovoltaic panel 5 after turning is covered with solar photovoltaic material.

[0009] Preferably, the solar photovoltaic panel 5 can be flipped downward by 80°-100°, and both sides of the solar photovoltaic panel 5 are provided with solar photovoltaic materials, so that it can generate solar power both when flipped and when not flipped.

[0010] Preferably, the height of the solar photovoltaic panel 5 covers the height of one deck layer.

[0011] Preferably, the height of the solar photovoltaic panel 5 covers the height of multiple decks.

[0012] Furthermore, the solar photovoltaic panel 5 is a foldable structure, which can be unfolded into a plane after being turned over, thereby expanding the photovoltaic area for receiving solar energy.

[0013] Preferably, the turning power mechanism is an electric motor or a hydraulic cylinder, and a transmission structure.

[0014] Preferably, solar photovoltaic panels are also arranged on the vacant parts of the open deck.

[0015] The present invention arranges solar photovoltaic equipment on the basis of the free area of ​​the upper open deck, and takes advantage of the large space of the outer plates on both sides of the car ro-ro ship to arrange solar photovoltaic equipment, so as to more effectively and fully utilize clean solar energy to generate electricity for daily electricity consumption of the ship and even for the ship's power system, thus helping the car ro-ro ship to save energy and reduce emissions, reduce operating costs, and improve its market competitiveness. At the same time, the present invention demonstrates the full application of renewable clean energy technology in the field of ships, sets an example for the industry, and promotes sustainable development.

[0026] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments.

[0027] The present invention makes full and effective use of the space of the side outer plate on the basis of arranging solar panels on the upper open deck, and arranges solar photovoltaic panels in a reasonable area on the upper part of the side outer plate to make fuller use of solar clean energy. The arrangement scheme for the side outer plate is as follows Figure 4 and Figure 5 As shown, the accompanying drawings of the present invention are only schematic diagrams. The number, size and distance between actual solar panels or photovoltaic panels can be reasonably adjusted according to the manufacturer's suggestions and construction technology during actual layout.

[0028] The solar photovoltaic equipment required by the present invention is mainly arranged in the non-perforated vertical plate area above the main deck (the main deck of the car roll-on / roll-off is generally 3 decks, 4 decks or 5 decks). It is difficult to arrange it in the curved plate area with linear changes, so it is not required here; at the same time, the area below the main deck is close to the full load waterline and is very likely to be affected by the load of the waves, which has a great impact on the safety and stability of the solar photovoltaic equipment, so it is not recommended to arrange it.

[0029] Solar photovoltaic equipment (solar panels or photovoltaic panels) are arranged on the outside of the side outer plates on both sides of the car roll-on / roll-off ship. There are multiple arrangement schemes in actual operation. Five typical schemes are introduced below, but other similar transformation schemes also fall within the protection scope of the present invention.

[0030] Embodiment 1:

[0031] A solar photovoltaic equipment arrangement structure for a car roll-on / roll-off ship is provided, wherein a solar photovoltaic panel 5 covering at least one deck height is provided on the ship outer plate 1 above the main deck 4, wherein the solar photovoltaic panel 5 rotates at the height of one of the upper decks 3 and can be turned up or down by 80°-100° under the drive of a self-contained turning power mechanism, and the upper surface of the solar photovoltaic panel 5 after turning is covered with solar photovoltaic material.

[0032] Specifically in this embodiment, the solar cell panel or photovoltaic panel 5 is suspended outside the outer panel 1 and parallel to the outer panel 1, and the panel 5 is in a fixed state and does not rotate or move. Figure 6 shown.

[0033] Embodiment 2:

[0034] On the basis of the first embodiment, the bottom solar panel or photovoltaic panel 6 can rotate around the upper edge of the panel, and the angle can be adjusted by intelligent rotation angle or manually operated machine or software according to the direction of light. The maximum rotation angle is 100 degrees, that is, perpendicular to the side outer plate 1. Figure 7As shown in the left figure, the rotating solar panel 7 and the upper fixed solar panel 5 receive solar energy at the same time, and the power generation efficiency is higher; when the wind and wave environment at sea is severe or there are other influences, the solar panel 7 can be dropped down, and the power generation efficiency after dropping down is the same as that of scheme one.

[0035] Embodiment three:

[0036] Similar to the second embodiment, the bottom solar panel or photovoltaic-6 in this solution is rotated around the lower edge of the panel to reach the required angle, and the rotated panel 7, such as Figure 7 As shown in the right figure. When encountering severe wind and wave conditions at sea or other influences, the solar panel 7 can be raised and placed, and the same as scheme 1 after being raised. At the same time, the bottom solar panel 6 of this scheme can adopt a single-layer panel scheme, or it can adopt a two-layer or multi-layer overlapping solar panel type suspended on the side outer plate 1. When the bottom solar panel -6 is fully raised, only the outer solar panel absorbs solar energy to work. When it is rotated to a certain angle, especially to the maximum angle (90 degrees) (this state is called 7), in addition to the bottom solar panel 7 rotated in place, the bottom inner layer solar panel 6 fixed on the side outer plate also starts to work. The bottom outer solar panel 7 of this scheme has special requirements, that is, both the front and back sides of the panel can absorb solar energy to work.

[0037] Embodiment 4:

[0038] like Figure 8 As shown in the left figure, the side solar panel or photovoltaic panel 6 adopts the type of an integral panel in the height direction (and multiple panels are used in the length direction according to the actual manufacturer's recommendation). The panel 6 can rotate around its upper edge and perform intelligent rotation angle according to the direction of light or manually operate the machine or software to adjust the angle. The maximum rotation angle is 90 degrees, that is, perpendicular to the side outer plate-1. The state at this time is called 7. When encountering severe wind and wave environment at sea or other influences, the panel 7 can be dropped and placed, which is similar to the first embodiment after dropping.

[0039] Solution 5: Similar to the fourth embodiment, the side solar panel or photovoltaic panel 6 is also in the form of a whole panel in the height direction, but the panel in this solution is rotated around its lower edge to reach the required angle. When the wind and wave environment at sea is bad or there are other influences, the panel can be raised and placed, and it is similar to solution 1 after being raised. At the same time, this solution can also use two or more layers of overlapping panels to be suspended on the side outer plate 1. When fully raised, only the outer panels of 6 absorb solar energy to work. When rotated to a certain angle, especially to the maximum angle (90 degrees), in addition to the rotated panels 7, the inner panels 6 fixed on the side outer plate 1 also start to work. The outer panels 7 of this solution have special requirements, that is, both the front and back sides of the panel can absorb solar energy to work.

[0040] In the second to fifth embodiments, no matter which scheme is used, the rotatable part can also be made into a way of overlapping multiple panels. After rotation, the internal folded panels can be unfolded as needed. After unfolding, it can generally reach 2 to 6 times the original width, thereby maximizing the role of the solar cell panel. Here, taking scheme 2 as an example, a schematic diagram of two or three layers of panels unfolded is briefly introduced. Fig. 9 .

[0041] For rotation, hydraulic or sliding methods can be used to achieve it. In order to ensure its safety and stability, for example, a support rod should be extended from the bottom or a stretching rod should be extended from the top after rotation. A reasonable structure and fixing device should be designed to ensure the stability and safety of the solar photovoltaic equipment during the ship's navigation. These are not the focus of the present invention and belong to the prior art in terms of implementation methods, so they are not described in detail here.

[0042] Among them, Embodiment 2 to Embodiment 5 are preferred embodiments.

[0043] Material requirements: Since the present invention sets solar photovoltaic equipment on the side, in order to reduce its negative impact, lightweight and durable solar panels or photovoltaic panels should be selected to minimize the increase in the weight of the upper part of the hull caused by the installation of solar panels, thereby reducing the impact on the stability and structural strength of the hull. In addition, solar panels or photovoltaic panels suitable for installation on board should be selected, which should have high efficiency, weather resistance and corrosion resistance to adapt to the marine environment.

[0044] Battery storage: According to the power generation capacity of solar or photovoltaic panels, batteries with sufficient capacity are set up to store the electricity generated by solar panels. The stored electricity can be used at night or on cloudy days when there is sufficient sunlight. When in use, a suitable inverter can be used to convert the DC power generated by absorbing solar energy into AC power for use.

[0045] Intelligent control: Since the angle of sunlight changes in different seasons and at different times, some solutions of the solar panels or photovoltaic panels of the present invention can intelligently adjust the normal of the panel according to the direction of sunlight, which can maximize the solar energy income and improve energy utilization efficiency.

[0046] Monitoring and management system: Set up a monitoring and management system to monitor the performance and operating status of solar photovoltaic equipment in real time. The system can provide data analysis and fault diagnosis to ensure efficient operation and maintenance of the system.

[0047] Space utilization: The side outer plate has a large space, and solar panels or photovoltaic panels are arranged on the upper part, which realizes the effective utilization of space without affecting the normal operation and transportation function of the ship.

[0048] Flexibility: The solar photovoltaic panels on both sides can be raised or lowered and adjusted according to actual conditions such as weather, light, port requirements, etc., which increases the flexibility and adaptability of the system.

[0049] In addition, the present invention is based on the better existing technology (i.e. the solution of installing photovoltaic solar panels on the upper open deck that has been applied), and installs solar photovoltaic panels on the side outer panels of both sides to more fully receive solar energy for more efficient power generation.

[0050] The present invention makes full use of the space utilization rate of the outer plates on both sides, and makes full use of clean renewable energy (solar energy) to help car roll-on / roll-off ships save energy and reduce emissions, effectively reduce operating costs, and improve market competitiveness; the various layout features of the side solar panels or photovoltaic panels show the flexibility of the layout and have a large potential for solar energy reception and conversion into electrical energy.

[0051] The above are optional embodiments of the present invention. Ordinary technicians in this field can also make respective changes or improvements on this basis. Without departing from the overall concept of the present invention, these changes or improvements are within the scope of protection required by the present invention.
