Description

Technical Field

[0001] The present invention relates to the technical field of offshore photovoltaic power generation, and in particular to a semi-submersible offshore photovoltaic power generation platform and an offshore photovoltaic power generation system. Background Art

[0002] Offshore photovoltaic power generation is a new energy utilization method that involves building solar photovoltaic power generation systems on the ocean. Photovoltaic panels directly convert solar energy into electricity. Its core principle is the photovoltaic effect: when sunlight strikes the surface of a photovoltaic cell (made of semiconductor material), the energy from photons excites electrons, generating an electric current. Compared to land-based photovoltaic power generation, offshore photovoltaic power generation significantly improves power generation efficiency by leveraging the ocean's vast expanse, unobstructed landscape, and prolonged sunshine hours.

[0003] Semi-submersible (floating) photovoltaic power stations use HDPE pontoons, stainless steel pontoons or high-strength composite concrete pontoons, combined with metal brackets to fix photovoltaic modules, and are suitable for areas with large water level fluctuations.

[0004] The Chinese invention patent with the announcement number CN114802627B discloses a semi-submersible offshore photovoltaic power generation platform and an offshore photovoltaic power generation array. The semi-submersible offshore photovoltaic power generation platform includes a platform frame, photovoltaic panels, floating columns, support assemblies, and at least two connecting parts. The platform frame is a spatial truss structure, including a plurality of connecting rods; each of the connecting rods is a hollow tubular structure; the peripheral side of the platform frame is inclined inward from top to bottom; a plurality of floating columns are located below the platform frame and are arranged in a one-to-one correspondence with the edges or corners of the cross-sectional shape of the platform frame; each of the floating columns can float on the sea level, and is partially located below the sea level and partially located above the sea level; a plurality of support assemblies are arranged in a one-to-one correspondence with the floating columns; each of the support assemblies includes a plurality of support rods, each of which is a hollow tubular structure; at least two connecting parts are arranged at adjacent corners of the top of the platform frame; each connecting part extends outward from the platform frame.

[0005] Although the technical solution recorded in the above patent avoids the problem of waves impacting the photovoltaic panels by increasing the distance between the photovoltaic panels and the sea surface, in actual use, since the entire platform adopts a semi-submersible structure, the photovoltaic panels will fluctuate on the sea surface due to the influence of waves, and the connection between the photovoltaic panels and the bracket is a rigid fixed connection, which can easily lead to stress concentration on the photovoltaic panels due to fluctuations, making it difficult to ensure the long-term stable operation of the photovoltaic panels.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] In the present invention, when the mounting frame fluctuates, a plurality of spring sheets will buffer the fluctuations, so that the fluctuations can be transmitted to the photovoltaic panel in a gentle manner. Although the spring sheets cannot completely buffer the fluctuations, they prevent the rigid direct transmission of the fluctuations, thereby achieving the first level of protection for the photovoltaic panel. Furthermore, since the spring sheets are arranged in a circular shape with equal spacing around the axis of the rubber tube, and the spring sheets are inclined, during the fluctuation process, when the distance between the photovoltaic panel and the mounting frame is reduced, that is, when the photovoltaic panel squeezes the plurality of spring sheets, the photovoltaic panel will generate a torsion relative to the mounting frame under the reaction force of the plurality of spring sheets, and the axis of this torsion is the axis of the rubber tube. At this time, although the rubber tube will generate a It will not only absorb a certain amount of torsion of the photovoltaic panel, but will also absorb part of the torsional force of the photovoltaic panel, so that the rubber tube can also buffer the fluctuations of the mounting frame. Moreover, when the distance between the photovoltaic panel and the mounting frame is reduced, the rubber tube itself will also bend to a certain extent in the direction of its axis, further buffering the fluctuations of the mounting frame. At the same time, since the sealed chamber inside the rubber tube is not connected to the external environment, when the distance between the photovoltaic panel and the mounting frame is reduced, the air pressure inside the sealed chamber increases, which once again buffers the fluctuations of the mounting frame. This achieves a second level of protection for the photovoltaic panel, avoids stress concentration between the photovoltaic panel and the mounting frame, and ensures that the photovoltaic panel can operate stably for a long time.

[0039] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] See also Figures 1-8 , the present invention provides a technical solution:

[0041] A semi-submersible offshore photovoltaic power generation platform includes a plurality of photovoltaic panels 1 and a mounting frame 4 disposed below the photovoltaic panels 1. The photovoltaic panels 1 and the mounting frame 4 are both prior art and will not be described in detail here. A flexible outer frame 2 is provided around the periphery of the photovoltaic panel 1, that is, an outer frame 2 is provided around the four sides of the photovoltaic panel 1. The specific material of the outer frame 2 is not limited here. For example, the outer frame 2 can be made of a rubber material resistant to salt spray corrosion. The function of the flexible outer frame 2 is to buffer the impact force when two adjacent photovoltaic panels 1 collide due to waves, thereby protecting the photovoltaic panels 1. A gap 3 is left between the two adjacent outer frames 2; the function of the gap 3 is to provide a basis for the buffering effect of the buffer frame 5 described below. Specifically, when the buffer frame 5 is in effect, the photovoltaic panel 1 will shake to a certain extent. At this time, the existence of the gap 3 can provide space for the shaking of the photovoltaic panel 1.

[0042] A buffer frame 5 is provided between the photovoltaic panel 1 and the mounting frame 4 for elastically connecting the photovoltaic panel 1 and the mounting frame 4; specifically, the buffer frame 5 includes a rubber tube 53 and a plurality of spring sheets 54, and the rubber tube 53 is made of salt spray resistant rubber material, wherein, Figure 4As shown, a number of spring sheets 54 are arranged in a circular shape with equal distances around the axis of the rubber tube 53; further, the top periphery and the bottom periphery of the rubber tube 53 are sealed and fixedly connected to the photovoltaic panel 1 and the mounting frame 4 respectively, so that a sealed chamber 57 is formed inside the rubber tube 53, which is used to protect the spring sheets 54 and other structures inside the rubber tube 53 and extend its use; the spring sheets 54 in the present technical solution are arranged at an angle, and their inclined top ends are fixedly connected to the photovoltaic panel 1, and their inclined bottom ends are fixedly connected to the mounting frame 4; in fact, when the photovoltaic panel 1 fluctuates, the photovoltaic panel 1 and the mounting frame 4 rotate closer or farther away, so that the rubber tube 53 and the spring sheets 54 jointly buffer the fluctuations of the photovoltaic panel 1.

[0043] In some embodiments, the spring piece 54 includes an inclined piece 541, a first mounting piece 543 fixed to the inclined top end of the inclined piece 541 through a first arc-shaped portion 542, and a second mounting piece 545 fixed to the inclined bottom end of the inclined piece 541 through a second arc-shaped portion 544; the first mounting piece 543 and the second mounting piece 545 are both provided with mounting holes 546, and the setting of the mounting holes 546 facilitates the installation and fixation of the spring piece 54 using structures such as bolts; the first arc-shaped portion 542 and the second arc-shaped portion 544 are both used to prevent stress concentration.

[0044] The basic principle of the above technical solution is: the fluctuation of the waves will drive the mounting frame 4 to fluctuate together, but since a buffer frame 5 is provided between the mounting frame 4 and the photovoltaic panel 1, the fluctuation of the mounting frame 4 will not be directly transmitted to the photovoltaic panel 1, but will be buffered by the buffer frame 5. Specifically, when the mounting frame 4 fluctuates, a number of spring sheets 54 will buffer the fluctuation, so that the fluctuation can be transmitted to the photovoltaic panel 1 in a gentle manner. Although the spring sheets 54 cannot completely buffer the fluctuation, they prevent the rigid direct transmission of the fluctuation, thereby realizing the first level of protection for the photovoltaic panel 1; further, since the spring sheets 54 are arranged in a circular and equidistant manner around the axis of the rubber tube 53, and the spring sheets 54 are inclined, during the fluctuation process, when the distance between the photovoltaic panel 1 and the mounting frame 4 is reduced, that is, when the photovoltaic panel 1 squeezes a number of spring sheets 54 , the photovoltaic panel 1 will produce a torsion relative to the mounting frame 4 under the reaction force of several spring leaves 54, and the axis of this torsion is the axis of the rubber tube 53. At this time, although the rubber tube 53 will produce a certain torsion, it will also absorb part of the torsional force of the photovoltaic panel 1, so that the rubber tube 53 can also buffer the fluctuations of the mounting frame 4. Moreover, when the distance between the photovoltaic panel 1 and the mounting frame 4 is reduced, the rubber tube 53 itself will also produce a certain degree of bending in the direction of its axis, further achieving the buffering of the fluctuations of the mounting frame 4; at the same time, since the sealed chamber 57 inside the rubber tube 53 is not connected to the external environment, therefore, when the distance between the photovoltaic panel 1 and the mounting frame 4 is reduced, the air pressure inside the sealed chamber 57 increases, once again achieving the buffering of the fluctuations of the mounting frame 4; thereby achieving a second level of protection for the photovoltaic panel 1.

[0045] In order to further improve the torsional resistance of the rubber tube 53 so that the rubber tube 53 can absorb more torsional force of the photovoltaic panel 1, in some embodiments, a spiral raised strip 534 can be provided on the circumference of the rubber tube 53, wherein the raised strip 534 can be provided on the inner circumference of the rubber tube 53 or on the outer circumference of the rubber tube 53, which is not limited here; further, the spiral direction of the raised strip 534 is opposite to the inclination direction of the spring sheet 54, and the purpose of such a setting is to further enhance the torsional resistance of the rubber tube 53.

[0046] In some embodiments, the buffer frame 5 further includes a top plate 51 and a bottom plate 52; the top plate 51 and the bottom plate 52 are both circular plate structures, the top plate 51 is fixedly connected to the bottom surface of the photovoltaic panel 1, and the specific fixing method is not limited here, for example, it can be welding or bolt connection, etc., the bottom plate 52 is fixedly connected to the mounting frame 4, and the specific fixing method is not limited here, for example, it can be welding or bolt connection, etc.; the top periphery and the bottom periphery of the rubber tube 53 are respectively sealed with the top plate 51 and the bottom plate 52. The rubber tube 53 is sealed and fixedly connected. Specifically, the rubber tube 53 includes an integrally formed cylindrical body 531, a first annular rim 532, and a second annular rim 533. A raised strip 534 is provided on the cylindrical body 531. The first annular rim 532 is pressed and fixed to the bottom plate 52 by a first pressure ring 55 and a fastener 58. The second annular rim 533 is pressed and fixed to the top plate 51 by a second pressure ring and a fastener 58. The fastener 58 in the above scheme can be a bolt. The top plate 51, the bottom plate 52, and the rubber tube 53 together form a sealed chamber 57. By limiting the buffer frame 5 to the above structure, the buffer frame 5 can be pre-assembled and then directly installed between the photovoltaic panel 1 and the mounting frame 4, which significantly shortens the construction period and improves construction efficiency.

[0047] A through hole 521 is provided at the center of the bottom plate 52, and a buffer seat 6 is provided at the bottom of the bottom plate 52; the buffer seat 6 includes a fixed cylinder 61 and a piston 62 provided inside the fixed cylinder 61 with a sliding seal, wherein the top end of the fixed cylinder 61 is fixed inside the through hole 521, and the top end surface of the fixed cylinder 61 is flush with the top end surface of the bottom plate 52, and the fixed cylinder 61 and the bottom plate 52 are sealed. For example, the fixed cylinder 61 is seamlessly connected to the bottom plate 52 by welding, and the piston 62 divides the internal space of the fixed cylinder 61 into a first air chamber 63 and a second air chamber 64, wherein the first air chamber 63 is connected to the sealed chamber 57. By providing the buffer seat 6, the cooperation between the fixed cylinder 61 and the piston 62 is utilized, so that when the sealed chamber 57 expands, the air inside it can directly enter the first air chamber 63, and the friction between the piston 62 and the fixed cylinder 61 is utilized to buffer the fluctuation of the mounting frame 4, and the buffering is smooth.

[0048] Furthermore, based on the above-mentioned piston 62 and fixed cylinder 61, in some embodiments, the buffer seat 6 further includes a guide sleeve 67 and a spring 69. The guide sleeve 67 is fixedly connected to the fixed cylinder 61 via a plurality of connecting arms 68, and is used to support the spring 69. Specifically, the two ends of the spring 69 are respectively fixedly connected to the guide sleeve 67 and the piston 62, and the spring 69 is coaxially arranged with the fixed cylinder 61. The top of the piston 62 is coaxially fixedly connected to a guide rod 66, the guide sleeve 67 is slidably connected to the guide rod 66, and the spring 69 is coaxially sleeved on the outside of the guide rod 66. The provision of the spring 69 can play an elastic role in limiting the sliding of the piston 62 inside the fixed cylinder 61. For example, when the air pressure inside the sealed chamber 57 increases, the piston 62 will overcome the friction between it and the inner wall of the fixed cylinder 61 and the elastic force of the spring 69 and slide downward, further buffering the ups and downs of the mounting frame 4.

[0049] In some embodiments, a rubber sleeve 65 is provided at the bottom end of the fixed cylinder 61 to seal the opening at the bottom end of the second air chamber 64, thereby preventing salt mist from entering the interior of the second air chamber 64 and protecting the piston 62. The rubber sleeve 65 includes an integrally formed spherical portion 651, an annular portion 652, and a sleeve portion 653. The sleeve portion 653 is sealingly mounted on the exterior of the fixed cylinder 61. Specifically, when the piston 62 moves downward due to an increase in air pressure within the sealed chamber 57, the air pressure within the second air chamber 64 increases, pushing the inwardly concave spherical portion 651 to gradually bulge outward, thereby further buffering the fluctuations of the mounting frame 4.
