Description

Technical Field

[0001] This utility model belongs to the field of shipbuilding, and specifically relates to a solar charging device for ships. Background Technology

[0002] Currently, solar charging panels have been gradually applied to inland waterway vessels, short-distance voyage vessels, and some special-purpose vessels. The typical application mode is as follows: the solar charging panels work in conjunction with the vessel's energy storage system and power system. During the day, the solar charging panels convert solar energy into electrical energy, part of which is directly supplied to the vessel's load, and the other part is stored in the energy storage system. During periods of poor sunlight or at night, the energy storage system releases electrical energy to ensure the operation of the vessel's equipment, thereby reducing the vessel's dependence on fossil fuels and improving energy utilization efficiency.

[0003] Although the application of solar charging panels in new energy ships has made some progress, the difficulty of laying solar charging panels due to space constraints on ships has always been the core technical bottleneck restricting their large-scale and efficient application.

[0004] As the core functional area of ​​a ship, the deck must simultaneously meet multiple critical needs: on the one hand, space must be reserved for the installation of equipment necessary for navigation, safety equipment, and operational equipment; on the other hand, for passenger ships, the deck must also include areas for personnel activities and rest. These functional requirements result in deck space being occupied by various equipment and functional areas, significantly reducing the space available for installing solar charging panels. This spatial conflict is particularly pronounced on function-intensive ships or small to medium-sized vessels, making it difficult to achieve large-scale deployment of solar charging panels and establish a stable energy supply capacity.

[0005] The inherent structural characteristics of ship hulls further limit the effective deployment range of solar charging panels: First, the hull's linear design does not match the deployment requirements of traditional solar charging panels. Traditional rigid solar charging panels require a high degree of flatness in the deployment surface, making it difficult to stably deploy them on curved hull sides or sloping deck areas. Even when using flexible solar charging panels, the unevenness of the hull surface leads to insufficient panel adhesion, thus affecting the solar energy absorption efficiency. Second, the layout of ship superstructures is relatively compact, limiting the space available for deploying solar charging panels on the top and sides. Furthermore, some areas are easily blocked by structures such as the bridge and equipment compartments, further reducing the effective light-receiving area of ​​the solar charging panels and making it impossible to fully utilize the available space resources on the ship.

[0006] The technical problem of inefficiently deploying solar charging panels due to space constraints on ships has not yet been effectively solved, and this issue has become a key bottleneck restricting the deep application of solar energy in ship energy systems. Therefore, it is urgent to propose a technical solution that can adapt to the spatial characteristics of ships and achieve efficient deployment of solar charging panels, so as to overcome the limitations of existing technologies and promote the green and efficient development of new energy ships.

[0033] Among them, there are solar panel 1, middle panel 1a, side panel 1b, corner panel 1c, first hinge plate 2, second hinge plate 3, support plate 4, upright pole 5, and flange 5a. Detailed Implementation

[0034] Example 1

[0035] like Figure 1-10 As shown, this embodiment includes a solar panel 1, a first hinge plate 2, a second hinge plate 3, and a support plate 4.

[0036] There are nine solar panels 1. All nine solar panels 1 are square panels of the same size. The nine solar panels 1 are arranged in a nine-square grid. The one in the middle is the middle panel 1a. The four sides of the middle panel 1a are the side panels 1b. The four corners of the middle panel 1a are the corner panels 1c.

[0037] like Figure 7 , 8 As shown, the front and back sides of the middle panel 1a are hinged to the front and back side panels 1b via the first hinge plate 2. Rotating the first hinge plate 2 allows the front and back side panels 1b to cover the upper and lower surfaces of the middle panel 1a respectively.

[0038] Similarly, the corner plates 1c on both sides of the front and rear side plates 1b of the middle panel 1a are also hinged by the first hinge plate 2. Rotating the first hinge plate 2 at this location allows the corner plates 1c, which are hinged to the front and rear side plates 1b of the middle panel 1a, to cover the upper and lower surfaces of the front and rear side plates 1b of the middle panel.

[0039] In this way, the nine-square solar panel 1 can be folded into three shapes of the same thickness arranged in a straight line.

[0040] like Figure 9 , 10As shown, in this embodiment, the left and right sides of the middle panel 1a are hinged to the left and right side panels 1b by the second hinge plate 3. Rotating the second hinge plate 3 can make the left and right side panels 1b cover the upper and lower surfaces of the middle panel 1a respectively, so that the straight solar panel 1 is folded into a block shape.

[0041] In this embodiment, the width of the first hinge plate 2 is approximately equal to the thickness of two solar panels 1, and the width of the second hinge plate 3 is approximately equal to the thickness of four solar panels 1.

[0042] Specifically, in this embodiment, elongated notches are provided on all four sides of the solar panel 1. The first hinge plate 2 and the second hinge plate 3 are both elongated strips with lengths corresponding to the notches. The elongated sides of the first hinge plate 2 and the second hinge plate 3 are located inside the notches and are hinged to the two sides of the notches via hinge shafts.

[0043] In this embodiment, the solar panel 1 has first slots with opposite openings on both sides of the notch. These first slots are blind holes. Second slots, also blind holes, are provided at both ends of the long sides of the first hinge plate 2 and the second hinge plate 3, opposite to the first slots. A hinge shaft is also provided; its two ends are inserted into the first and second slots respectively to hinge the solar panel 1 to the first hinge plate 2 and the second hinge plate 3.

[0044] The support plate 4 is hinged to the bottom surface of the middle panel 1a. The support plate 4 can rotate around the hinge axis. After rotation, the support plate 4 can be completely retracted under the middle panel 1a, or it can be rotated to simultaneously support the two adjacent side panels 1b and the corner plate 1c between the two adjacent side panels 1b. After the solar panel 1 is fully unfolded into a nine-square grid shape, the support plate 4 can support the middle panel 1a, the two adjacent side panels 1b, and the corner plate 1c between the two adjacent side panels 1b, preventing them from folding back.

[0045] In this embodiment, support plates 4 are provided at each of the four corners of the bottom plate of the middle panel. The support plates 4 are right-angled fan-shaped, and the right-angled ends of the support plates 4 are hinged to the corners of the bottom surface of the middle panel 1a. This structure maximizes the area of ​​the support plates 4, allowing as much area as possible to contact the solar panel 1 during lifting, thus improving the stability of the lifting. The arc-shaped ends of the fan-shaped support plates 4 prevent interference with other support plates 4 during rotation.

[0046] Preferably, this embodiment also provides a support pole 5, the bottom end of which is provided with a base, and the top end of the support pole 5 is detachably connected to the bottom surface of the middle panel 1a.

[0047] Furthermore, in this embodiment, a flange 5a is provided at the top of the upright 5, and the flange 5a is bolted to the bottom surface of the intermediate panel 1a. The flange 5a can increase the supporting area, but at least when the support plate 4 is rotated to the supporting position, the flange 5a does not interfere with the support plate 4.

[0048] In this embodiment, the solar panel 1 is unfolded into a nine-square grid structure during use. Then, uprights 5 are installed to support the nine-square solar panel 1. The uprights 5 can be placed on the deck, thus not hindering the movement and work of people on deck, allowing for solar charging, and even providing shade for the solar panels 1. When the weather is bad or the panel is not in use, the uprights 5 are removed, the support plate 4 is rotated, and the nine-square solar panel 1 is folded back in, making it very convenient to use.

[0049] Example 2

[0050] The difference between this embodiment and embodiment 1 is that the solar panel 1 in this embodiment is rectangular and only five pieces are provided, namely, only the middle panel 1a and four side panels 1b provided on the front, back, left and right sides of the middle panel 1a. The middle panel 1a and the four side panels 1b form a cross shape.

[0051] In addition, this embodiment does not provide a second slot, but instead provides hinge shafts corresponding to the first slot at both ends of the long sides of the first hinge plate 2 and the second hinge plate 3.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
