In this embodiment, the solar photovoltaic power generation device 1 includes a bearing assembly 2, a first flip assembly 3, a first solar assembly 4 and a first driving member 5. The bearing assembly 2 is arranged on the side of the cargo hold S1 of the transport ship S. The bearing assembly 2 has a pivot point 201. The first flip assembly 3 is connected to the pivot point 201. The first flip assembly 3 includes a first flip plate 31. The first flip plate 31 extends along the length direction of the cargo hold S1 and is located on one side of the width direction of the cargo hold S1. The first flip plate 31 is horizontally arranged and extends outward from the side of the ship S2, so as to expand the installation area of ​​the solar panel in the side area of ​​the transport ship S.

[0025] As mentioned above, the first solar module 4 is arranged on the first flip plate 31. The first solar module 4 includes a plurality of first polygonal pyramid trusses 41 and a plurality of first solar panels 42. The plurality of first polygonal pyramid trusses 41 are arranged on the first flip plate 31 in a staggered array. The plurality of first solar panels 42 are arranged on each surface of the plurality of first polygonal pyramid trusses 41. By designing the trusses of the first solar panels 42 as a polygonal pyramid structure and placing them in a staggered array, not only can the first solar panels 42 capture sunlight to the maximum extent and improve the power generation efficiency of the solar panels, but also the overall strength of the solar panel trusses can be ensured to meet the requirements.

The first flip plate 31 can block the first solar panel 42 from being damaged by objects that may fall during unloading or loading.

[0027] For further information, see Figure 4 Also see Figure 1 As shown, Figure 4It is a cross-sectional schematic diagram of a solar photovoltaic power generation device applied to a transport ship of the utility model; as shown in the figure, the solar photovoltaic power generation device 1 also includes a second flip assembly 6, a plurality of second solar components 7 and a second driving member (not shown in the figure).

The second flip plate 61 is horizontally arranged and extends outward from the side of the ship's side S2, thereby expanding the installation area of ​​the solar panel in the other side area of ​​the transport ship S. Therefore, the solar photovoltaic power generation device 1 of this embodiment expands the installation area of ​​the solar panel in the two side areas of the transport ship S through the first flip plate 31 and the second flip plate 61.

[0028] As mentioned above, a plurality of second solar modules 7 are arranged on the second flip plate 61. The second solar module 7 includes a plurality of second polygonal pyramid trusses 71 and a plurality of second solar panels 72. The plurality of second polygonal pyramid trusses 71 are arranged in a staggered array on the second flip plate 61, and the plurality of second solar panels 72 are arranged on each surface of the plurality of second polygonal pyramid trusses 71. Like the first solar panel 42, by designing the trusses of the second solar panels 72 as polygonal pyramid structures and placing them in a staggered array, not only can the second solar panels 72 capture sunlight to the maximum extent, improve the power generation efficiency of the solar panels, but also ensure that the overall strength of the solar panel trusses meets the requirements. The first driving member 5 is arranged on the bearing assembly 2, and the action end of the first driving member 5 is connected to the first flip assembly 3. The second driving member is arranged on the bearing assembly 2. The action end of the second driving member is connected to the second flip assembly 6. The second driving member is configured to drive the second flip assembly 6 to rotate around the pivot point 201, so as to flip the second flip plate 61 to the same side of the cargo warehouse S1 as the first flip plate 31, and make the second flip plate 61 in a flipped and tilted state.

When the transport ship S is unloading or loading, since only one side of the transport ship S is close to the dock, if the transport ship S has one side of the first solar module 4 close to the dock, refer to Figure 4 As shown, the first flip plate 31 can be flipped to the other side. If the side with the second solar panel 7 is close to the dock, the second flip plate 61 can be flipped to the other side. This can avoid affecting the unloading or loading, and also avoid damage to the solar panel caused by objects that may fall during unloading or loading.

[0030] Specifically, the solar photovoltaic power generation device 1 of this embodiment is applied to a transport ship S with a total length of 63 meters and a beam of 12.6 meters.

Therefore, the solar photovoltaic power generation device 1 of this embodiment can increase the power generation by 147.4kw / h compared to installing photovoltaic panels only on the ceiling of the crew room and the ceiling of the cab, which is more than 7 times. According to the two 300KW diesel units conventionally installed on the transport ship S, and based on the fuel consumption of 25 liters per 100 kWh, full power operation can save 42 liters of diesel per hour. In addition, if photovoltaic panels are installed on the expanded area on both sides of the ship, the ceiling of the crew room, and the ceiling of the cab at the same time, the total power generation is 188.7kw / h (based on the single crystal silicon photovoltaic panel m 2 / 0.2kw / h), then full power operation can save 47.17 liters of diesel per hour.
