Description

Technical Field

[0001] The present invention relates to an ocean photovoltaic power generation device, and particularly to an offshore floating support. Background Art

[0002] Currently, offshore photovoltaic power stations are mainly divided into two types: pile-fixed type and floating type. The pile-fixed type is suitable for sites with relatively shallow water levels, no geological disasters such as site subsidence, and small water level changes. The floating offshore photovoltaic power station is suitable for deep sea areas and replaces the ground piles through anchoring, with higher flexibility. However, the existing floating photovoltaics have problems such as low structural strength, poor stability, and poor wave resistance. Therefore, how to improve the stability, wave resistance, and corrosion resistance of offshore floating photovoltaics has become a technical difficulty in the development of ocean floating photovoltaics.

[0003] An existing offshore floating support structure uses a circular floating body as the core, sets a central floating body in the center of the circular floating body, sets a flexible support between the two floating bodies, connects the photovoltaic support to the floating body by pulling ropes, sets a convex part on the central floating body for misaligned fixation of multiple parallel installation ropes, and both ends of the installation ropes are connected to the floating body for hanging photovoltaic modules. At the same time, a tensioning rope is arranged inside the floating body perpendicular to and intersecting with the installation rope to form a grid-like wave-resistant structure. A column is added on the top of the foam floating body to enhance the overall rigid support.

[0004] It has the following deficiencies:

[0005] 1. The photovoltaic array is suspended by steel strands, and the steel strands need to be tensioned regularly, resulting in high construction and maintenance costs;

[0006] 2. The sagging of the steel strands causes the components to be compressed and deformed, and there is a lack of rigid connection between the arrays, making them easy to collide and damage in the wind and waves.

[0007] 3. A central floating body must be set at the center position of the circular floating body for anchoring the steel strands. The steel strands are staggered at the center position, which is not convenient for subsequent inspection, maintenance, and passage. Summary of the Invention

[0048] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0049] Refer to Figures 1 - 12 The present invention provides an offshore floating support, the structural design of which aims to improve the overall structural stability and durability, and ensure the efficient power generation of photovoltaic panels under different sea conditions. Specifically, it includes a first floating body 1 and a support array.

[0050] In this application, the first floating body 1 is circular ring-shaped, which can float on the water surface and provide stable support. As an important structural part of the offshore floating support, at the same time, this circular ring-shaped floating body can protect the support array inside it, avoiding direct impact of sea waves or other objects, reducing structural damage, and providing guarantee for the stable operation of the photovoltaic components (such as photovoltaic panels) inside the first floating body 1.

[0051] In this application, the first floating body 1 is a tubular structure with its head and tail connected. Its interior is hollow, which can effectively disperse the seawater pressure, enhance buoyancy, and has a lower center of gravity, good stability, and strong anti-wind and wave ability. In this embodiment, the first floating body 1 is made of HDPE, that is, high-density polyethylene, which is a thermoplastic plastic made by polymerizing ethylene monomers; it has the following advantages: high strength, good rigidity; strong chemical corrosion resistance, with extremely strong resistance to chemical substances such as acids, alkalis, salts, alcohols, and oils; low water absorption, good low-temperature toughness, light weight and easy to process. Therefore, the circular ring-shaped first floating body made of it has good strength and durability, and can maintain long-term stable operation in extreme marine environments.

[0052] The bracket array is located inside the first floating body 1, that is, within the circular ring. The bracket array serves as the installation carrier for the photovoltaic panel 3 and is used to install the photovoltaic panel 3. The bracket array includes multiple bracket units 2. The bracket unit 2 is a rigid bracket, and the multiple bracket units 2 are distributed in a circular array around the axis of the first floating body 1 to form the bracket array. For ease of description, the end of the bracket unit 2 away from the axis of the first floating body 1 is defined as the tail, and the end of the bracket unit 2 close to the axis of the first floating body 1 is defined as the head. The tail of the bracket unit 2 is connected to the first floating body 1, and the heads of two adjacent bracket units 2 are fixedly connected by a rigid connecting member 94. A second floating body 4 is provided at the lower end of the bracket unit 2. The second floating body 4 can provide buoyancy for the bracket unit 2 and enable it to float independently on the water surface.

[0053] In this application, the tail of the bracket unit 2 can be connected to the first floating body 1 through a hoop or through a bolt. When using a hoop connection, a cable is provided at the tail of the bracket unit 2. The cable is a steel strand. A hoop is connected to the end of the steel strand through a bow shackle and is connected to the first floating body 1 through the hoop, thereby realizing the flexible connection between the tail of the bracket unit 2 and the first floating body 1. The above-mentioned hoop consists of two semi-circular parts, which are clamped and fixed on the first floating body 1 through bolts. Therefore, there is no need to drill anchoring holes on the first floating body 1, avoiding the risk of water leakage of the circular first floating body, improving its use reliability and service life, and greatly reducing the assembly and maintenance costs at the same time. At the same time, since the bracket array and the first floating body 1 are flexibly connected, when the first floating body outside the bracket array is impacted by sea waves, the impact force can be prevented from being directly transmitted to the bracket array, improving the overall impact resistance of the bracket and ensuring the operation stability of the bracket unit 2 and the photovoltaic components on the bracket unit. Since the water in the ocean is easy to corrode the hoop, the bracket with a hoop structure is suitable for freshwater lakes.

[0054] Refer to Figure 8 , when using a bolt connection, an installation hole penetrates through the first floating body 1. The axis of the installation hole is perpendicular to and intersects with the axis of the first floating body 1. Preferably, the axis of the first installation hole passes through the center of the cross-section of the first floating body. A bolt body 22 is sleeved in the installation hole. First clamping plates 23 and second clamping plates 24 that can fit on the surface of the first floating body are respectively provided at both ends of the bolt body. Sealing members are provided between the first clamping plate 23 and the first floating body 1 and between the second clamping plate 24 and the first floating body 1 for sealing to prevent water from entering the first floating body through the gap and affecting the buoyancy. This method is suitable for the ocean and has good corrosion resistance.

[0055] To improve the space utilization rate inside the first floating body 1, in this application, the support unit 2 includes a first support unit 2a and a second support unit 2b. The effective installation length of the second support unit 2b is less than that of the first support unit 2a. The effective installation length is the effective length for installing photovoltaic panels. Since the first floating body is annular, the closer to the center of the first floating body, the smaller the radius. Therefore, the space for installing photovoltaic panels is also smaller. To avoid interference between adjacent photovoltaic panels, the above alternating arrangement structure is adopted to improve the space utilization rate. The first support unit 2a and the second support unit 2b are arranged in a circular array in an alternating manner inside the first floating body 1. That is, during assembly, they are arranged in a cycle in the order of one first support unit 2a, one second support unit 2b, one first support unit 2a, one second support unit 2b. The distances from the tails of the first support unit 2a and the second support unit 2b to the first floating body are basically the same. The distances from the heads of the first support unit 2a and the second support unit 2b to the center of the first floating body 1 can be the same or different. Preferably, they are the same, which is convenient for overall installation and fixation. The numbers of the above first support unit 2a and second support unit 2b are the same. The two sides of the head of the first support unit 2a are connected to the heads of the adjacent second support unit 2a through a rigid connecting member 94. Refer to Figure 5 , the rigid connecting member 94 is a rigid member, which can be in a plate shape or a rod shape. Installation holes are provided in the rigid connecting member 94 for fixed connection with the ends of the support unit through bolts to form a rigid structure. This rigid connecting member can keep the distance between the heads of adjacent two support units constant and avoid collision under the influence of sea waves. One or more third connecting rods 93 are connected between adjacent two support units. The third connecting rods are connected between adjacent two support units through bolts. The third connecting rods are rigid rods, thereby ensuring that the distance between adjacent two support units is constant and avoiding collision.

[0056] To facilitate the overall construction and daily maintenance, in this application, there is a spacing (distance) between the head of the support unit 2 and the axis (center) of the first floating body 1, thereby forming a polygonal maintenance space 70 in the center of the support array, which is convenient for maintenance personnel to enter and exit and perform maintenance operations.

[0057] In this application, a central floating body 7 is further included. The central floating body 7 is arranged at the central position of the first floating body 1. At the same time, the head of the support unit 2 is connected to the central floating body 7 through a first connecting rod 91, thereby improving the structural strength of the overall framework. A central hole penetrates through the central floating body 7 to form a maintenance space 70, that is, the maintenance space 70 is annular. In this embodiment, the aperture of the maintenance space is 0.5 m - 1 m, which is convenient for maintenance operations. The central floating body 7 includes an annular central floating body main body 71. The inner wall of the central hole of the central floating body main body 71 extends upward to form a cylindrical first strengthening part 72. A strengthening rib 73 is provided between the first strengthening part 72 and the upper surface of the central floating body main body 71. The first strengthening ribs are multiple and evenly distributed circumferentially. An installation area is formed between adjacent two strengthening ribs. Installation holes are provided in the installation area. The number of installation areas is the same as the number of the first connecting rods 91. The end of the first connecting rod 91 is installed in the installation area. Through the above structural arrangement, the structural strength of the central position of the support array can be improved, thereby improving the anti-wind and wave resistance and extending the service life. The central floating body can be a floating cylinder or foam, or foam is filled in the floating cylinder.

[0058] In order to further improve the structural strength, in this application, the first connecting rod 91 is fixedly connected to a rigid connecting piece 94, which is located between the longitudinal beams of two adjacent support units. And two adjacent first connecting rods 91 are connected by a second connecting rod 92 or a second floating body 4, so that a rigid frame structure is also formed between adjacent first connecting rods.

[0059] The structures of the first support unit 2a and the second support unit 2b are the same. The structure of the support unit 2 will be described in detail below:

[0060] The support unit 2 includes two longitudinal beams 21 that are parallel to each other or form a certain angle. The two longitudinal beams 21 are connected by a third connecting rod and / or a second floating body 4 to form a rigid frame structure. And the tails of the two longitudinal beams 21 are both connected to the first floating body 1 by bolts, and the two sides of the front end are connected to the adjacent support unit 2 through a rigid connecting piece 94. Specifically, the rigid connecting piece 94 is connected to the support unit 2 (longitudinal beam) by bolts.

[0061] In order to facilitate production, processing and manufacturing, in this application, the two longitudinal beams 21 are parallel to each other, so that the support unit 2 forms a rectangular frame structure. At the same time, the length direction (center line) of the support unit 2 is parallel to the radial direction of the first floating body 1.

[0062] In this application, the longitudinal beam is a BFRP composite purlin. BFRP, namely basalt fiber reinforced composite material, is a high-performance composite material with basalt fiber as the reinforcing material and thermosetting or thermoplastic resin as the matrix. It combines the high strength and corrosion resistance of basalt fiber with the toughness of the resin matrix; it has the advantages of high strength, light weight, good corrosion resistance, high temperature resistance, fatigue resistance and creep resistance.

[0063] The above-mentioned longitudinal beam 21 is of a profile structure. In this application, its cross-section is a U-shaped structure, that is, similar to the channel steel structure, and the open end is arranged upward, which is convenient for the arrangement of the installation components of the photovoltaic panel and can be used to place the cables of the photovoltaic module. And both sides of the open end at the upper end of the longitudinal beam are bent 90 degrees outward or inward to form a strengthening part; there are hole bodies on the longitudinal beam 21, and these hole bodies are arranged at equal intervals along the length direction of the longitudinal beam 21. As installation holes, they are convenient for assembly and can select different hole bodies for assembly according to different installation positions; in this application, the above-mentioned first connecting rod, second connecting rod, third connecting rod and fourth connecting rod also adopt the same profile as the longitudinal beam, which reduces the production cost and improves the assembly efficiency at the same time.

[0064] The photovoltaic panel 3 is fixed on the support unit through the installation components. In this application, the photovoltaic panels 3 are arranged at equal intervals along the length direction of the support unit 2. At the same time, they are inclined in the radial direction towards the first floating body 1, and the inclination angle is greater than 0 degree and less than or equal to 5 degrees to prevent water accumulation on the surface of the photovoltaic panel.

[0065] The structure of the installation component will be described as follows:

[0066] Example 1: Refer to Figure 11 and Figure 12, the cross-section of the longitudinal beam is U-shaped with its open end facing upward. The mounting assembly is arranged in the groove of the cross beam. Specifically, the mounting assembly includes a front column 51, a rear column 52 and a support member 6. The front column 51 and the rear column 52 are fixed in the groove of the longitudinal beam 21, and the structures of the front column 51 and the rear column 52 are the same, except for the difference in height, thus forming a height difference and an angle, that is, forming the inclined installation of the photovoltaic panel; the widths of the front column 51 and the rear column 52 are basically the same as the width of the groove of the longitudinal beam. Therefore, their side walls are in contact with the inner wall of the groove, and thus the connection strength is high and the anti-wave ability in the horizontal direction is strong; the bottom surfaces of the front column and the rear column extend to both sides to form a connecting portion, and mounting holes are provided on the connecting portion for connecting with the bottom surface of the groove of the longitudinal beam through bolts; support members 6 are provided at the tops of both the front column 51 and the rear column 52. The support member 6 includes a first support plate 61. In this embodiment, the cross-section of the first support plate 61 is triangular. A second support plate 62 is vertically fixed at the front end of the first support plate 61. A support area is formed between the first support plate 61 and the second support plate 62, which is used to contact and support the edge of the photovoltaic panel. Mounting holes are provided on the second support plate 62 for realizing the fixed connection with the photovoltaic panel; a fixing plate 63 is provided at the rear end of the first support plate 61, which is used to connect with the top of the front column 51 or the rear column 52. Mounting holes are also provided on the fixing plate 63 for connecting with the tops of the front and rear columns through bolts. The plane where the fixing plate 63 is located is parallel to the length direction of the support area and is inclined to the second support plate 62, and the inclination angle is 3-10 degrees, so as to ensure the fitting degree of the edge of the photovoltaic panel in the support area during assembly. Specifically, the lower end of the photovoltaic panel fits with the surface of the second support plate, and the side wall of the photovoltaic panel fits with the surface of the first support plate; in this application, the second support plate 62 is arranged at the center of the first support plate 61, thus forming two symmetrical support areas. Therefore, during assembly, only the front and back installation of the support member on the front and rear columns is required, reducing the production cost. To enhance the stability of the photovoltaic panel, an elastic material gasket is further adopted in this design. The gasket is placed between the second support plate and the photovoltaic panel,

[0067] Embodiment 2, refer to Figures 9 - 10, which is different from the embodiment in the structure of the installation component. In this embodiment, the open end of the longitudinal beam is arranged downward. The installation component includes a first installation part 51' and a second installation part 52'. Among them, the first installation part 51' includes a first plate body 511'. The end of the first plate body 511' is bent upward obliquely to form a second plate body 512'. The bending angle is 1-5°. Installation holes are provided on both the first plate body and the second plate body. The first installation part 51' is used to connect the lower inclined end of the photovoltaic panel; the second installation part 52' includes a third plate body 521'. The upper and lower ends of the third plate body 521' are bent in opposite directions to form a fourth plate body 522' and a fifth plate body 523' respectively. The included angle between the fourth plate body 522' and the fifth plate body 523' is 1-5 degrees. At the same time, installation holes are provided on both the fourth plate body 522' and the fifth plate body 523' for connecting with the longitudinal beam and the photovoltaic panel. The second installation part 52' is used to connect the upper inclined end of the photovoltaic panel.

[0068] In this application, the two longitudinal beams of the support unit 2 are fixedly connected through the second floating body 4 to form a rigid frame structure; there are multiple second floating bodies 4, and they are arranged in sequence along the length direction of the support unit 2. In this embodiment, the second floating body 4 is strip-shaped, preferably rectangular, and its length direction is perpendicular to the length direction of the support unit 2. Its length is greater than or equal to the width of the support unit 2 and less than or equal to the length of the photovoltaic panel; the second floating body 4 includes a support 42 and a floating body main body 41. The support 42 is used to be fixedly connected with the support unit. The second floating body 4 can be a floating cylinder or foam, or foam is filled in the floating cylinder.

[0069] The floating offshore support of the present invention adopts independent support units to form a modular design, which is compact in structure, low in manufacturing cost, and convenient for construction and maintenance. The support units adopt a rigid structure, significantly improving the stability and load-bearing capacity of the entire floating offshore support. The longitudinal floating bodies are provided to further enhance the structural strength and thus improve the resistance to wind and waves. Rigid connectors are used to connect adjacent support units, making the connection more flexible and stable, avoiding collisions between adjacent support units. In practical applications, this design can also significantly reduce the displacement and vibration of the support caused by waves and ocean currents, thereby protecting the photovoltaic panels from damage and greatly improving the resistance to wind and waves. The connecting rods are connected by bolts to form hinge points and have a certain degree of rotational freedom. When subjected to impacts, they can form a slight offset, thereby dispersing external forces, enhancing the toughness of the entire support system, and preventing the impact force from being transmitted to adjacent support units, improving the overall structural stability and resistance to wind and waves of the array support. The alternating arrangement of support units improves the space utilization rate and ensures a certain distance between the heads of support units, avoiding mutual influence by wind and waves. Maintenance intervals are provided for convenient construction and daily maintenance. The floating offshore support of the present invention adopts a modular design, is compact in structure, convenient for construction, has strong resistance to wind and waves, does not require frequent maintenance, has low manufacturing and maintenance costs, and has a long service life.

[0070] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
