Description

Technical Field

[0001] The utility model belongs to the technical field of offshore photovoltaics, and in particular relates to an annular breakwater for offshore floating photovoltaics. Background Art

[0002] In recent years, the number of floating photovoltaics at sea has gradually increased. Currently, they are mainly installed in shallow sea areas near land. This is because the waves and undercurrents in shallow sea areas have little impact on floating photovoltaics. In deep sea areas, there are a large number of horizontal waves and undercurrents from bottom to top. If a large number of floating photovoltaics need to be deployed in deep sea areas, it is necessary to minimize the impact of waves and undercurrents on floating photovoltaics, that is, to set up breakwaters.

[0003] At present, the breakwaters used for offshore floating photovoltaics are mostly made of floating plastic barrels or foam tubes arranged in a ring and connected to each other in order to reduce their own weight. However, such breakwaters cannot weaken the impact of undercurrents from the bottom up on photovoltaics, that is, undercurrents in deep sea areas can easily cause damage to photovoltaic areas. In addition, ordinary breakwaters are also weak in their ability to break larger horizontal waves. Utility Model Content

[0004] The utility model aims to provide an annular breakwater for offshore floating photovoltaics, which solves the problem that the photovoltaic area body of the existing offshore photovoltaic brackets is easily damaged due to the undercurrent of seawater from bottom to top.

[0005] The technical solution adopted by the utility model is an annular breakwater for offshore floating photovoltaics, comprising an annular floating member internally connected to a photovoltaic area body, the inner side of the annular floating member is circumferentially hinged to the middle parts of a plurality of L-shaped connecting members, the bottom end of each L-shaped connecting member is connected to a wave receiving plate, and each wave receiving plate is inclined; the top end of each L-shaped connecting member is fixedly connected to a first fixing ring, and a plurality of first fixing rings are connected to the same first ring-shaped shape memory alloy wire, the bottom end of each L-shaped connecting member is fixedly connected to a second fixing ring, and a plurality of second fixing rings are connected to the same second ring-shaped shape memory alloy wire.

[0006] The utility model is also characterized in that:

[0007] The bottom of the photovoltaic area body is connected to one end of a plurality of mooring cables, and the other end of each mooring cable is fixed to the pile foundation through an anchor.

[0008] The photovoltaic region body is a photovoltaic region structure formed by connecting a plurality of photovoltaic panels.

[0009] The bottom of the photovoltaic area body is also connected to an air bag.

[0010] The annular floating member is evenly connected to the photovoltaic area body through a plurality of elastic connecting ropes.

[0011] The back side of each wave receiving plate is fitted and connected with a hollow floating block.

[0012] The beneficial effects of the utility model are:

[0013] The utility model is an annular breakwater for offshore floating photovoltaic power generation, based on the fact that waves and undercurrents at sea will generate horizontal impacts and bottom-up impacts on the breakwater. The horizontal impact will cause the wave-receiving plate to have a tendency to rotate downward around the connection point between the annular floating member and the L-shaped connecting member, while the bottom-up impact will cause the wave-receiving plate to have a tendency to rotate upward around the connection point between the annular floating member and the L-shaped connecting member. Since the first shape memory alloy wire and the second shape memory alloy wire are also provided at both ends of the L-shaped connecting member, when the waves and undercurrents at sea are large, the energy is dissipated through the expansion of the first shape memory alloy wire and the second shape memory alloy wire (reducing the bottom-up impact on the entire photovoltaic device), thereby reducing the influence of undercurrents or wind and waves on the overall structure; when the waves and undercurrents at sea are small, the first shape memory alloy wire and the second shape memory alloy wire will return to their original state.

DETAILED DESCRIPTION

[0019] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0020] Example 1

[0021] The utility model is a circular breakwater for offshore floating photovoltaic, such as Figure 1 , Figure 2 and Figure 3As shown, it includes an annular floating member 7 internally connected to the photovoltaic area body 3, and the inner side of the annular floating member 7 is circumferentially hinged with multiple L-shaped connecting members 4, specifically hinged at the middle part of the L-shaped connecting member 4, the bottom end of each L-shaped connecting member 4 is connected to the wave-receiving plate 1, and each wave-receiving plate 1 is inclined. The top of each L-shaped connecting member 4 is fixedly connected to the first fixing ring 6, and the multiple first fixing rings 6 are all connected to the same first ring-shaped shape memory alloy wire 5, and the bottom end of each L-shaped connecting member 4 is fixedly connected to the second fixing ring 10, and the multiple second fixing rings 10 are all connected to the same second ring-shaped shape memory alloy wire 8.

[0022] The photovoltaic region body 3 is a photovoltaic region structure formed by connecting a plurality of photovoltaic panels.

[0023] The annular floating member 7 is an annular floating structure capable of floating on the sea surface.

[0024] like Figure 4 As shown, the long limbs of the multiple L-shaped connectors 4 and the first shape memory alloy wire 5 are located above the horizontal plane, and because their bodies are relatively slender, they only slightly block or do not block the sunlight from irradiating the photovoltaic area body 3.

[0025] In the initial state, the wave receiving plate 1 keeps being inclined, that is, the wave receiving plate 1 should have a certain projection area on the horizontal plane, so that the undercurrent from bottom to top acts on the wave receiving plate 1 .

[0026] In the initial state, the top edges of the plurality of wave-receiving plates 1 are located in the horizontal plane, which is convenient for early installation and later maintenance.

[0027] The annular floating member 7 is used to connect the photovoltaic area body 3 and the L-shaped connecting member 4. Since the L-shaped connecting member 4 is hinged on the annular floating member 7, when wind and waves or undercurrents act on the wave-receiving plate 1, the L-shaped connecting member 4 is subjected to force and can rotate around the annular floating member 7. Since the two ends of the L-shaped connecting member 4 are respectively connected to the first shape memory alloy wire 5 and the second shape memory alloy wire 8, during the rotation of the L-shaped connecting member 4, the first shape memory alloy wire 5 or the second shape memory alloy wire 8 can be expanded to achieve the effect of dissipating energy, thereby reducing the damage of wind and waves or undercurrents to the photovoltaic area body 3. When the waves and undercurrents at sea are small, the first shape memory alloy wire 5 and the second shape memory alloy wire 8 can be restored to their original state.

[0028] Sea waves and undercurrents will produce horizontal impacts and bottom-up impacts on the breakwater. The horizontal impact will cause the wave-receiving plate 1 to have a tendency to rotate downward around the connection point between the annular floating member 7 and the L-shaped connector 4, while the bottom-up impact will cause the wave-receiving plate 1 to have a tendency to rotate upward around the connection point between the annular floating member 7 and the L-shaped connector 4. The two types of waves will eventually only cause one wave-receiving plate 1 to have a rotation tendency. When the horizontal impact mainly impacts the wave-receiving plate 1, the first shape memory alloy wire 5 will have an expansion tendency and dissipate energy. When the horizontal impact becomes smaller, the first shape memory alloy wire 5 will restore the multiple wave-receiving plates 1 to their original state by relying on its own characteristics. When the bottom-up undercurrent mainly impacts the wave-receiving plate 1, the second shape memory alloy wire 8 will have an expansion tendency and dissipate energy (reducing the impact of the entire photovoltaic device from bottom to top). When the bottom-up impact becomes smaller, the second shape memory alloy wire 8 will restore the multiple wave-receiving plates 1 to their original state by relying on its own characteristics.

[0029] The bottom of the photovoltaic area body 3 is connected to one end of a plurality of mooring cables 9 , and the other end of each mooring cable 9 is fixedly connected to the pile foundation through an anchor, which can fix the photovoltaic area body 3 .

[0030] The bottom of the photovoltaic area body 3 is also connected to an air bag, so that the photovoltaic area body 3 always keeps a floating state.

[0031] Example 2

[0032] On the basis of Example 1, in this embodiment, the annular floating member 7 is evenly connected to the photovoltaic area body 3 through multiple elastic connecting ropes 11. In Example 1, when multiple wave-bearing plates 1 are mainly impacted in the horizontal direction, the annular floating member 7 will also be moved by the impact of waves. In this process, multiple elastic connecting ropes 11 are relied on to achieve an elastic and tight connection.

[0033] Example 3

[0034] On the basis of Example 1, in this embodiment, the back side of each wave-receiving plate 1 is fitted with a hollow floating block 2, which can increase the buoyancy of the wave-receiving plate 1 and enable the wave-receiving plate 1 to rotate upward around the connection point between the annular floating member and the L-shaped connecting member in the initial state, so that the initial state of the wave-receiving plate 1 remains inclined, that is, the projection area of ​​the wave-receiving plate 1 on the horizontal plane is larger.

[0035] Through the above-mentioned method, the annular breakwater for offshore floating photovoltaic of the utility model is based on the fact that the waves and undercurrents at sea will produce horizontal impacts and bottom-up impacts on the breakwater. The horizontal impact will cause the wave-receiving plate to have a tendency to rotate downward around the connection point between the annular floating part and the L-shaped connecting part, while the bottom-up impact will cause the wave-receiving plate to have a tendency to rotate upward around the connection point between the annular floating part and the L-shaped connecting part. The rotation of the wave-receiving plate buffers the impact of the waves and undercurrents at sea on the photovoltaic area body. In the utility model, a first shape memory alloy wire and a second shape memory alloy wire are also provided. When the waves and undercurrents at sea are large, the energy is dissipated by the expansion of the first shape memory alloy wire and the second shape memory alloy wire (reducing the bottom-up impact on the entire photovoltaic device); when the waves and undercurrents at sea are small, the first shape memory alloy wire and the second shape memory alloy wire will return to their original state.
