Description

Technical Field

[0001] The utility model relates to the technical field of offshore photovoltaic power generation, in particular to an offshore photovoltaic power station. Background Art

[0002] Offshore photovoltaic power stations refer to power stations in the ocean that use solar photovoltaic technology to convert sunlight into electricity. Compared with onshore photovoltaic power stations, offshore photovoltaic power stations face more challenges in environmental conditions, engineering construction, and operation and maintenance.

[0003] For example, offshore photovoltaic power stations face more severe environmental conditions, such as wind and waves, salt spray, etc., which put higher requirements on the durability and corrosion resistance of photovoltaic modules.

[0004] In addition, offshore construction is difficult and costly. The construction of offshore photovoltaic power stations requires special floating bodies or support structures to adapt to the marine environment. At the same time, operation and maintenance also face problems such as bad weather and difficult maintenance.

[0005] However, offshore photovoltaic power stations also have their unique advantages. First, the ocean is vast and has huge development potential. It is predicted that offshore photovoltaic power generation will become an important development direction in the field of renewable energy in the future. Secondly, offshore photovoltaic power stations are generally far away from densely populated areas and have less interference with people's lives. Finally, offshore photovoltaic power stations can be combined with other marine resource utilization in some cases, such as aquaculture, tourism, etc.

[0006] At present, offshore photovoltaic power stations can be roughly divided into two types: floating power stations and fixed power stations. However, these two types of power stations are generally only suitable for offshore waters or mudflats within 30 kilometers from the shore and within a water depth of 100 meters. For the deep sea with more complex environment, these two technical solutions cannot guarantee the safety of the power station, and the construction cost of the power station will also increase exponentially. Utility Model Content

[0007] The utility model aims to provide an offshore photovoltaic power station which can operate safely in deep sea areas.

[0008] In order to solve the above technical problems, the utility model provides an offshore photovoltaic power station.

[0009] The utility model provides an offshore photovoltaic power station, comprising three support members, the three support members are distributed in a triangle, and the three support members are respectively a first support member, a second support member and a third support member;

[0010] It also includes three outer trusses, all of which are arched, namely a first outer truss, a second outer truss and a third outer truss;

[0011] Two ends of the first outer truss are connected to the first support member and the second support member respectively, two ends of the second outer truss are connected to the second support member and the third support member respectively, and two ends of the third outer truss are connected to the third support member and the first support member respectively;

[0012] Two adjacent outer trusses are connected by at least one reinforced inner truss;

[0013] The first outer truss, the second outer truss and the third outer truss form a circumferential closed frame, and a plurality of photovoltaic panels are arranged in the circumferential closed frame.

[0014] Furthermore, the reinforced inner truss is arched.

[0015] Further, the first support member, the second support member and the third support member are arranged in an equilateral triangle.

[0016] Furthermore, two ends of a reinforced inner truss between two adjacent outer trusses are respectively connected at equally divided points of the two adjacent outer trusses.

[0017] Furthermore, two adjacent outer trusses are connected via a reinforced inner truss, and two ends of a reinforced inner truss between two adjacent outer trusses are respectively connected to the midpoints of the two adjacent outer trusses.

[0018] Furthermore, a bearing member is provided between two adjacent outer trusses, and the photovoltaic panel is provided on the bearing member.

[0019] Furthermore, a bearing member is provided between two adjacent reinforced inner trusses, and the photovoltaic panel is provided on the bearing member.

[0020] Furthermore, the bearing member is a flexible steel cable.

[0021] Furthermore, the support member includes a frame and a pile foundation for fixing the frame on the seabed, and the end of the outer truss is fixedly connected to the end of the frame.

[0022] Furthermore, the frame is a catheter frame.

[0023] Compared with the prior art, the utility model has at least the following beneficial effects:

[0024] Since the three arched outer trusses form a special triangular structure with three arched sides, the structural stability of the triangle is strong and the stability of the truss arch is also strong, so the stability and safety of the overall structure are also strong. The two adjacent outer trusses are connected by at least one reinforced inner truss, which further improves the stability of the overall structure and makes the offshore photovoltaic power station have a strong ability to withstand severe sea conditions.

[0025] At the same time, the truss arch has a strong spanning capacity, which is conducive to the use of large-span truss arches to increase the number of installed photovoltaic panels, thereby helping to increase the power generation of offshore photovoltaic power stations and reduce power generation costs.

[0033] The present invention is described in more detail in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the accompanying drawings are in very simplified form and in non-precise proportions, and are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0034] The following is attached to the instruction manual Figure 1 and attached Figure 2 , the offshore photovoltaic power station of the utility model is introduced.

[0035] In one embodiment, if Figure 1 and Figure 2 As shown, the offshore photovoltaic power station includes three support members 10 and three outer trusses 20 .

[0036] The three support members 10 are distributed in a triangle shape, and the three support members 10 are respectively a first support member 10 , a second support member 10 and a third support member 10 .

[0037] The three outer trusses 20 are all arched, namely the first outer truss 20, the second outer truss 20 and the third outer truss 20. The two ends of the first outer truss 20 are respectively connected to the first support member 10 and the second support member 10, the two ends of the second outer truss 20 are respectively connected to the second support member 10 and the third support member 10, and the two ends of the third outer truss 20 are respectively connected to the third support member 10 and the first support member 10, so that the three arched outer trusses 20 constitute a special triangular structure with three arched sides, and the triangle is supported by three support members 10.

[0038] Two adjacent outer trusses 20 are connected via at least one reinforced inner truss 30 .

[0039] The first outer truss 20 , the second outer truss 20 and the third outer truss 20 form a circumferential closed frame, and a plurality of photovoltaic panels 40 are arranged in the circumferential closed frame.

[0040] Since the three arched outer trusses 20 form a special triangular structure with three arched sides, and since the triangular structure is relatively stable and the truss arch is also relatively stable, the stability and safety of the overall structure are also relatively strong. The two adjacent outer trusses 20 are connected by at least one reinforced inner truss 30, thereby further improving the stability of the overall structure, so that the offshore photovoltaic power station has a strong ability to withstand severe sea conditions.

[0041] At the same time, the truss arch has a strong spanning capacity, which is conducive to using a large-span truss arch to increase the number of photovoltaic panels 40 installed, thereby facilitating increasing the power generation of the offshore photovoltaic power station and reducing the power generation cost.

[0042] Preferably, in one embodiment, in order to further improve the structural stability of the offshore photovoltaic power station, the reinforced inner truss 30 is also configured to be an arch. In other embodiments, the reinforced inner truss 30 can also be a linear structure.

[0043] In one embodiment, the first support member 10, the second support member 10 and the third support member 10 are distributed in an equilateral triangle, and the three outer trusses 20 form a special equilateral triangle with three arched sides. On the one hand, the difficulty of designing components is reduced, which is conducive to large-scale and batch production. On the other hand, it is convenient to arrange the offshore photovoltaic power station cluster in the form of array distribution.

[0044] In one embodiment, only one reinforced inner truss 30 is arranged between two adjacent outer trusses 20, that is, three reinforced inner trusses 30 are arranged in three outer trusses 20. Preferably, the two ends of the reinforced inner truss 30 are respectively connected to the midpoints of two adjacent outer trusses 20. When the three outer trusses 20 form an equilateral triangle with three arched sides, the three reinforced inner trusses 30 form an equilateral triangle, thereby further improving the stability of the overall structure. In other embodiments, the reinforced inner truss 30 can also be arranged at the four-equal division between two adjacent outer trusses 20, and six reinforced inner trusses 30 are arranged in the circumferential closed frame. The more the number of reinforced inner trusses 30 is, the stronger the stability of the overall structure is. In other embodiments, the reinforced inner trusses can also be arranged at the three-equal division or the five-equal division. Of course, the number of equal divisions cannot be too many, and there is no need to arrange too many reinforced inner trusses to avoid excessive self-weight of the structure.

[0045] In one embodiment, in order to fix the photovoltaic panel 40, a bearing member is provided between two adjacent outer trusses 20, and the photovoltaic panel 40 is provided on the bearing member. Furthermore, a bearing member for arranging the photovoltaic panel 40 is also provided between two adjacent reinforced inner trusses 30. For example, Figure 1As shown, only two adjacent reinforced inner trusses 30 are provided with bearing members, and no bearing members are provided between another reinforced inner truss 30 and the remaining two reinforced inner trusses 30. Of course, in other embodiments, bearing members may also be provided between any two adjacent reinforced inner trusses 30.

[0046] Preferably, the bearing member is a flexible steel cable 50, and the photovoltaic panel 40 is fixed on the flexible steel cable 50. By applying a suitable pre-tightening force on the flexible steel cable 50, the wind resistance of the photovoltaic panel 40 can be improved. In other embodiments, the bearing member can also be a rigid connecting rod.

[0047] In one embodiment, the support member 10 includes a frame and a pile foundation for fixing the frame to the seabed, and the end of the outer truss 20 is fixedly connected to the end of the frame. The pile foundation can be a caisson, which is a steel cylinder with a sealed upper end and an open lower end, and is buried in the seabed foundation when in use. The shape of the caisson can be square, rectangular or cylindrical. In this embodiment, it is preferably cylindrical.

[0048] In one embodiment, the tower frame is preferably a pipe frame, which is a frame structure formed by welding a plurality of tubular structures such as steel pipes or aluminum alloy pipes. In other embodiments, the support member 10 may also be a concrete column.

[0049] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
