Description

Technical Field

[0001] This utility model relates to the field of photovoltaic floating platform technology, and more specifically, to a waterborne photovoltaic floating platform. Background Technology

[0002] Floating photovoltaic (PV) power plants install solar panels on a floating platform, which allows the PV panels to float on the water surface and generate electricity. The electricity produced is transmitted to the grid via cables. Compared to land-based PV power plants, floating PV power plants have many advantages, such as saving land resources, reducing water evaporation, and inhibiting algae growth. In recent years, they have been rapidly adopted in lakes, reservoirs, and nearshore areas. However, existing technologies still have the following drawbacks: Insufficient platform stability: Most existing floating platforms use rigid connections, which are prone to structural stress concentration under wave and wind loads, especially shear stress in the vertical direction, leading to connection point fractures (for example, floating platforms are fixed with bolts, which are prone to fatigue failure).

[0003] Some existing designs use cables to secure adjacent floating platforms, thus avoiding stress concentration that occurs when adjacent floating platforms are rigidly connected, thereby extending the service life of components. However, while cable connections solve the stress concentration problem, the lack of restraint makes adjacent floating platforms prone to collisions in windy or wave-filled conditions. Utility Model Content

[0004] To address at least one of the aforementioned problems, this utility model first provides a floating photovoltaic platform, comprising: multiple floating units arranged on the surface of a water body, the top surface of each floating unit being used to install photovoltaic modules; a connecting component connecting adjacent floating units in each row and column; the connecting component employing a flexible connection in the direction of each row and column to allow relative movement between adjacent floating units; and a separating component disposed between adjacent floating units in the direction of each row and column; at least a portion of the separating component continuously protruding from the water surface to separate adjacent floating units.

[0005] Optionally, the connecting component is a cable or chain disposed on the floating unit; the cable or chain fixes adjacent floating units in the direction of each column.

[0006] Optionally, the floating unit has an anchor at its edge for securing the connecting assembly; the anchor has a straight rod portion and bends downward at the top of the straight rod portion to form a hook; the connecting assembly is fitted onto the straight rod portion of the anchor along the hook.

[0007] Optionally, the separating component is a buoy; the cable or the chain passes through the buoy.

[0008] Optionally, a rope is fixed to the bottom of the floating unit, and an anchor is fixed to the end of the rope; the rope has redundant length so that the anchor will not float up when the water reaches its highest level.

[0009] Optionally, each row of adjacent floating units is connected by a float to form a channel for maintenance.

[0010] Optionally, a swing rod is pivotally connected to both sides of the float; each swing rod is pivotally connected to the floating unit so that the float and the floating unit can move relative to each other.

[0011] Optionally, multiple hinges are fixedly installed in the middle of the swing rod to be hinged to the floating unit; the swing rod has a U-shaped structure and a rotating hole is provided at the opening of the U-shaped structure; the float has a rotating shaft at its four corners; the rotating shaft is rotatably connected to the inner wall of the rotating hole.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0023] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0024] This utility model provides a floating photovoltaic platform on water, such as Figure 1 As shown, it includes: multiple floating units 1 arranged on the surface of the water, the top surface of the floating units 1 being used to install photovoltaic modules; connecting components 2, which connect two adjacent floating units 1 in each row and column, so that each floating unit 1 does not float too far away; the connecting components 2 are flexibly connected in each row and column direction, so that adjacent floating units 1 can move relative to each other, thus ensuring that adjacent floating units 1 will never be separated, and can maintain a certain degree of relative movement when encountering wind and waves; separating components 3, which are set between two adjacent floating units 1 in each row and column direction; at least a part of the separating components 3 is continuously exposed above the water surface to separate adjacent floating units 1; the separating components 3 are made of plastic or rubber.

[0025] like Figure 1 As shown, the connecting component 2 is a cable or chain disposed on the floating unit 1; the cable or chain fixes adjacent floating units 1 in the direction of each column.

[0026] like Figure 1As shown, the floating unit 1 has anchors 101 for fixing the connecting component 2 on its edge; the anchors 101 can be set along each edge of the floating unit 1, and multiple anchors 101 can be set on each edge of the floating unit 1. Each anchor 101 is connected to a separator component 3 through the connecting component 2, so that multiple separator components 3 are provided between adjacent floating units 1, further reducing the probability of adjacent floating units 1 colliding; or multiple connecting components 2 can be fixed on one anchor 101, and each connecting component 2 is connected to multiple separator components 3, which can also achieve a similar technical effect; specifically: the anchor 101 has a straight rod part, and the top of the straight rod part is bent downward to form a hook part 102; the connecting component 2 is sleeved on the straight rod part of the anchor 101 along the hook part 102, so that the connecting component 2 can be easily sleeved on the anchor 101 during installation; the anchor 101 has a simple structure.

[0027] like Figure 1 As shown, the separating component 3 is a buoy; cables or chains pass through the buoy; the main function of the buoy is to separate adjacent floating units 1 to prevent collisions between different floating units 1.

[0028] In one embodiment, such as Figure 3 As shown, a rope 103 is fixed to the bottom of the floating unit 1, and an anchor 104 is fixed to the end of the rope 103. The anchor 104 is sunk into the mud in the water to prevent the floating unit 1 from floating too far and becoming uncontrollable. If the rope 103 and the anchor 104 are not provided, an anchoring structure needs to be set at the edge of the array of floating units 1 to fix the floating unit 1 to the fixed object on the shore. The rope 103 has a redundant length so that the anchor 104 will not float up when the water reaches the highest water level, thereby preventing the anchor 104 from pulling the floating unit 1 down in its natural state and preventing the floating unit 1 from drifting away with the anchor 104 when the water rises or the water level is high.

[0029] like Figure 2-4As shown, each row of adjacent floating units 1 is connected by a float 4, forming a channel for maintenance. This facilitates subsequent maintenance workers to repair and replace the photovoltaic modules, and also facilitates the transportation and installation of the photovoltaic modules during installation. The device of this utility model is generally installed on rivers or inland lakes. A swing rod 5 is pivotally connected to both sides of the float 4; each swing rod 5 is pivotally connected to the floating unit 1, allowing relative movement between the float 4 and the floating unit 1. Multiple hinges 501 are fixedly installed in the middle of the swing rod 5 to hinge with the floating unit 1; the swing rod 5 has a U-shaped structure and a rotating hole at the opening of the U-shape; the float 4 has a rotating shaft 502 at its four corners; the rotating shaft 502 is rotatably connected to the inner wall of the rotating hole. This allows adjacent floating units 1 to float or move relative to each other, maintaining a certain degree of freedom. Compared to the traditional large-area array of floating units 1 connected by a fixed connection, which easily causes vertical shear stress in the fixed connection parts between the floating unit 1 and adjacent floating units 1, the hinge structure described above in this utility model has a certain ability to resist wind and waves and reduces the vertical shear stress in the fixed connection parts between the floating unit 1 and adjacent floating units 1.

[0030] In one embodiment, such as Figure 4 As shown, ropes 6 are fixed at both ends of the float 4 to secure adjacent floats 4 in each column direction; this keeps adjacent floats 4 relatively fixed, thus forming a relatively stable maintenance channel.

[0031] In one embodiment, a separator 3 is provided between adjacent floats 4 in each column direction; the separator 3 is not shown in the figure. The separator 3 can also be a buoy structure. The buoy has a floating function, and since part of the buoy is above the water surface, it also serves to separate the floats 4 and prevent them from colliding. Alternatively, an anti-collision structure, such as a buffer pad, can be provided on the buoy. The separator 3 here prevents adjacent floats 4 from colliding. In another embodiment, the two ends of the floats 4 extend as far as possible so that the two floats 4 are close to each other, allowing maintenance workers to pass easily. In this case, a separator 3 is not necessary between the two floats 4.

[0032] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
