Description

Technical Field

[0001] The utility model relates to the technical field of floating photovoltaic power stations, and particularly relates to a floating body, a floating array and a floating photovoltaic power station. Background Art

[0002] In recent years, floating photovoltaic power stations have been widely applied to various scenarios such as drinking water reservoirs, hydropower station reservoirs, offshore waters and extremely cold regions due to their safe, reliable and environmental protection characteristics. The foundation of a floating photovoltaic power station is usually composed of a floating array formed by multiple floating bodies. The multiple floating bodies are sequentially connected in the length direction to provide an installation space for photovoltaic equipment. Currently, a lug structure with a straight cross-sectional configuration is usually arranged on the floating body for connection. The anti-shear ability of this lug structure is weak, which will cause the photovoltaic modules arranged on the upper part to be greatly affected by water surface fluctuations, thus affecting the power generation efficiency and the operation and maintenance experience of the operation and maintenance personnel on the floating power station. At the same time, due to the fluctuation effect of the water surface, a large stress concentration effect will be caused on the root of the lug, and the root of the lug is easily damaged by fatigue in waters with strong winds and waves. In severe cases, it will lead to the disintegration of the floating photovoltaic power station and cause great economic losses.

[0003] Therefore, how to improve the connection strength of the floating body, improve the connection reliability of the floating body and the operation and maintenance experience of the floating power station is a technical problem that needs to be solved urgently by those skilled in the art. Summary of the Utility Model

[0004] In view of this, the purpose of the utility model is to provide a floating body to improve its connection strength and connection reliability and the operation and maintenance experience of the floating photovoltaic power station.

[0005] Another purpose of the utility model is to provide a floating array including the above-mentioned floating body.

[0006] Another purpose of the utility model is to provide a floating photovoltaic power station including the above-mentioned floating array.

[0007] A floating body includes a main body, a first lug and a second lug. The first lug and the second lug are arranged on opposite sides of the main body.

[0008] Two spaced connection holes are respectively formed in the first lug and the second lug. Adjacent floating bodies are butted against each other through the bending areas on one first lug and one second lug. After butt joint, the connection holes on the single-group first lug and second lug are aligned and fixedly connected by bolts.

[0032] The core of the present utility model is to provide a floating body to improve its connection strength and connection reliability, and improve the operation and maintenance experience of the floating power station on the water surface.

[0033] Another object of the present utility model is to provide a floating square array including the above floating body.

[0034] Another object of the present utility model is to provide a water surface photovoltaic power station including the above floating square array.

[0035] In order to enable those skilled in the art to better understand the solution of the present utility model, the embodiments of the present utility model will be described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the utility model recorded in the claims in any way. In addition, all the contents shown in the following embodiments are not limited to what is necessary for the solution of the utility model recorded in the claims.

[0036] As Figure 1 And Figure 2As shown in the figure, the floating body provided by the embodiment of the present utility model mainly includes a main body 10, a first ear 20 and a second ear 30. Among them, the main body 10 is the main structural part of the floating body, and it is mostly designed as a cavity structure to provide buoyancy to support the weight of the entire floating body and the upper load-bearing equipment. The first ear 20 and the second ear 30 are respectively arranged on opposite sides of the main body 10. It should be noted that the opposite sides on the main body 10 specifically refer to the two side surfaces on the main body 10 without contact edges. For example, if the floating body is an approximately cuboid structure, its opposite sides are two parallel structural surfaces. The main functions of the first ear 20 and the second ear 30 are to realize the connection between multiple floating bodies so that the floating bodies can be effectively combined together. In particular, the first ear 20 and the second ear 30 are respectively provided with bending areas 40 with the same number and capable of completely fitting in the thickness direction of the main body 10. Here, it should be noted that for the bending areas 40 on the first ear 20 and the second ear 30 to be able to completely fit, the first ear 20 and the second ear 30 need to be arranged at different positions in the thickness direction of the main body 10, that is, there is a certain height difference between the bending areas 40 on both sides, so that when the main bodies 10 of the two floating bodies are kept flush, the bending areas 40 on the first ear 20 and the second ear 30 can fit. The design of the bending area 40 allows adjacent floating bodies to be butted through the fitting of the bending areas 40 of the first ear 20 and the second ear 30, thereby enhancing the stability and integrity of the floating body structure.

[0037] On this basis, the first ear 20 and the second ear 30 are respectively provided with two connecting holes 50 arranged at intervals. When adjacent floating bodies are butted through a pair of first ear 20 and second ear 30, the two connecting holes 50 arranged on their structures are aligned to enable fixed connection through bolts, which is not only convenient and fast, but also has sufficient reliability and stability. The bending areas 40 are provided on the first ear 20 and the second ear 30, which can increase the contact area of the first ear 20 and the second ear 30 while keeping the original area of the structural surface of the main body 10, thereby enhancing the connection strength of the first ear 20 and the second ear 30, making the connection of the floating body structure more compact, reducing the influence of hydrodynamic force on the floating body structure. At the same time, the bending structure is based on the original straight cross-section structure. It improves the bending and shear resistance of a pair of ear structures through surface contact in the thickness direction of the main body 10, reducing the stress concentration effect of water surface fluctuations on the ears and the floating body, improving the anti-wave effect of the floating body, and enhancing the fatigue life of the floating body and the operation and maintenance experience of the upper part of the floating body.

[0038] It should be noted that in the above embodiments, the structures of the first lug 20 and the second lug 30 are highly similar, but their setting positions in the thickness direction of the main body 10 are different. Although adjacent floating bodies can be connected through two first lugs 20, the floating bodies cannot be kept flush and a stepped joint will occur. Therefore, in some embodiments of the present invention, markings can be provided on both sides of the main body 10 where the first lug 20 and the second lug 30 are provided. For example, Arabic numerals "1" and "2" can be marked, or English letters "A" and "B" can be marked. Taking the marking of Arabic numerals "1" and "2" as an example, when assembling personnel connect the floating bodies, it is necessary to ensure that the side marked with "1" on a single floating body is docked with the side marked with "2" on the adjacent floating body to be assembled, so as to realize the connection of a pair of the first lug 20 and the second lug 30 and maintain the correct assembly of the floating bodies, avoiding stepped joints during the assembly of the floating bodies and affecting subsequent use.

[0039] In the floating body provided by the embodiment of the present invention, the first lug 20 and the second lug 30 for connecting adjacent floating bodies are arranged at different positions in the thickness direction of the main body 10. At the same time, bending areas 40 are respectively arranged on the first lug 20 and the second lug 30, so that through the offset structure, while keeping the main body 10 aligned for adjacent two floating bodies, the bending areas 40 on a pair of the first lug 20 and the second lug 30 can be fitted and docked. On this basis, through holes 50 are arranged on the first lug 20 and the second lug 30 to lock a pair of the first lug 20 and the second lug 30 through bolts. The setting of the bending area 40 can increase the contact area of the first lug 20 and the second lug 30 while keeping the original area of the structural surface of the main body 10, thereby improving the connection strength of adjacent floating bodies and reducing the damage risk of the floating bodies. At the same time, the bending structure can enable the first lug 20 and the second lug 30 to have a surface contact effect in the thickness direction of the main body 10, thereby improving the bending resistance and shear resistance strength after the connection of the first lug 20 and the second lug 30, reducing the stress concentration effect of water surface fluctuations on the lugs, improving the connection stability of the floating bodies, and being applicable to various harsh water areas, thus improving the general applicability of the floating bodies.

[0040] Further, in order to improve the connection stability of a set of first lugs 20 and second lugs 30, in some embodiments of the present utility model, the first lug 20 is provided with straight sections 210 parallel to the upper surface of the first lug 20 on both sides of the bending area 40. It should be noted that here, both sides specifically refer to that when only one bending area 40 is provided, the straight sections 210 are provided at both ends of the single bending area 40, and when more than one bending area 40 is provided, the straight sections 210 are provided on the outer sides of the two bending areas 40 at both ends; the setting of the straight sections 210 protects the bending area 40 in the first lug 20 on the one hand, improves the structural stiffness of the first lug 20 and the overall load-bearing capacity of the floating body. At the same time, the connection holes 50 are all provided on the straight sections 210, which is convenient for the operator to pass through and lock the bolts in the plane area, and can also improve the penetration and fixing effect of the bolts, ensuring the stability of the connection of the floating body; it should be noted that the second lug 30 is also provided with straight sections 210, and its structure is similar to that of the first lug 20, and will not be elaborated here.

[0041] In some embodiments of the present utility model, the first lug 20 and the second lug 30 are of equal length, so that the connection strength on both sides is uniform, avoiding the risk of tearing when the water surface fluctuates due to uneven connection strength on both sides of the floating body. At the same time, taking the first lug 20 as an example for illustration, the first lug 20 is fixedly arranged on the first connection surface 110 of the main body 10, and it can be fixed by a connecting piece or integrally produced. At the same time, the first lug 20 spans the first connection surface 110 in the first direction. It should be noted that the first direction is the extending direction of the first lug 20, that is, on a single direction on the first connection surface 110, the first lug 20 is provided in a through manner to maintain the maximum setting length of the first lug 20 in the setting direction, so as to ensure the connection area and structural strength when the first lug 20 is connected; the consistency of the lengths of the first lug 20 and the second lug 30 makes the connection between adjacent floating bodies more balanced, reducing the stress concentration caused by uneven connection. At the same time, the design of the first lug 20 spanning the first connection surface 110 increases the connection area of the floating body, improving the stability and reliability of the connection; similarly, the setting structure of the second lug 30 is similar to that of the first lug 20, and will not be elaborated here.

[0042] On the basis of the above embodiments, in order to ensure the connection convenience and stability of adjacent floating bodies, the first lug 20 is preferably vertically arranged on the first connection surface 110, that is, the extended structure area of the first lug 20 based on the first connection surface 110 maintains a state perpendicular to the first connection surface 110, so as to improve the assembly convenience during the fitting process. The vertical structure can more effectively disperse and bear the vertical force under the same material consumption, reducing the risk of deformation and damage of the floating body structure.

[0043] Considering that the floating body is greatly affected by the water surface fluctuations during its use on the water surface, in some embodiments of the present invention, a flexible gasket layer is provided on the mutually facing surfaces of the first ear 20 and the second ear 30. That is, for a pair of mutually fitting and butting first ear 20 and second ear 30, there is a flexible gasket area between them when they are in contact, so that on the basis of maintaining a stable connection, the floating body has a certain floating ability. On the one hand, it can provide additional buffering and protection effects, reduce the friction and wear between the floating bodies, and extend the service life of the floating bodies. On the other hand, the floating bodies connected in a sheet can be adjusted to float to a certain extent through the gasket layer in a local area under the influence of the water surface fluctuations, thereby reducing the floating effect of the overall connection structure of the floating bodies and improving the operation and maintenance detection experience of the personnel on the floating bodies.

[0044] Specifically, in some embodiments of the present invention, as Figures 3 - 6 shown, the bending area 40 is designed as an arc bending structure to better meet the connection requirements between the floating bodies, providing a larger contact area and better fit. At the same time, the arc bending structure can enable a slight relative sliding effect between adjacent floating bodies, which is applicable to areas with a relatively complex water area environment. It can limit the water surface action to a limited floating body connection area while maintaining the stable effect of the overall connection structure; at the same time, a straight connection end is provided between adjacent arc bending structures to separate the two bending areas 40, which helps to maintain the stability of the bending area 40 and avoid structural deformation caused by misalignment or improper connection of continuous arc areas.

[0045] In some other embodiments of the present invention, as Figure 1 , Figure 2 , Figure 7 and Figure 8 shown, the bending area 40 is set as an isosceles triangle structure. At the same time, at least two bending areas 40 are provided on the first ear 20, and the base length and the protruding height of the bending area 40 are equal. The bending area 40 with an isosceles triangle structure can provide better support and connection effects, ensuring the close fit between the floating bodies. At the same time, the consistency of the base length and the protruding height makes the connection of the bending area 40 more uniform, reducing the stress concentration caused by uneven connection. It should be noted that compared with the bending area 40 with an arc structure, the bending area 40 with an isosceles triangle structure can make the adjacent floating bodies have a weaker relative movement effect and a stronger integrity. It is applicable to waters with a certain fluctuation risk but not too complex water surface conditions. The local floating bodies have a certain self-adjustment function, and at the same time, the integral structure is strong to maintain a stable support effect.

[0046] In addition, in some other embodiments of the present invention, as Figures 9 - 11As shown, the bending area 40 is designed as a U-shaped structure. At the same time, the adjacent inner walls on the bending area 40 are vertically arranged. When a pair of first lugs 20 and second lugs 30 are butted, the U-shaped bending area 40 is clamped and connected to provide a larger contact area and better fit, enhancing the connection effect between the floating bodies. At the same time, the vertically arranged inner walls help to improve the stiffness of the bending area 40 and prevent structural deformation caused by improper connection. It should be noted that the bending area 40 of the U-shaped structure has a high connection strength, and there is no space for relative movement between adjacent floating bodies. It is applicable to waters with relatively stable water surface conditions and can form a good integral support structure to meet the stable support of the equipment.

[0047] Furthermore, the embodiment of the present invention also provides a floating matrix, which includes a plurality of floating bodies connected in sequence. The first lug 20 of each floating body is attached and fixed to the second lug 30 of the adjacent floating body, and the second lug 30 of the floating body is attached and fixed to the first lug 20 of the adjacent floating body on the other side to form a stable floating body network, which can bear a greater weight and more complex structure. The design of the floating matrix provides greater buoyancy and stability and is applicable to the installation and use of various water facilities, such as photovoltaic panels, fishery aquaculture facilities, etc. At the same time, the modular design of the floating matrix is also convenient for installation, maintenance and expansion.

[0048] Furthermore, the embodiment of the present invention also provides a floating photovoltaic power station, which uses the floating matrix provided by the above embodiment as a support foundation to make full use of the water surface space, effectively reduce land use, and avoid damaging the water area ecological environment. In addition, the flexibility and scalability of the floating matrix also provide convenience for the construction and maintenance of the photovoltaic power station.
