Description

Technical Field

[0001] This invention relates to the field of photovoltaic power generation technology, and specifically to a connection structure for a marine photovoltaic floating body. Background Technology

[0002] Photovoltaics refers to a new type of power generation technology that converts solar energy into electrical energy. To reduce land occupation, photovoltaic power stations have been moved from land to sea, utilizing photovoltaic technology to build power stations on the ocean. This method features high power generation, less land occupation, and ease of integration with other industries. Compared to onshore photovoltaics, marine photovoltaics have natural environmental advantages.

[0003] Floating photovoltaic power stations are divided into two main categories: fixed pile foundation type and floating type, each with its own applicable scenarios. Generally, if the water depth is less than 5m, a pile foundation type installation is used, while if the water depth is greater than 5m, a floating type installation can be used.

[0004] Existing floating systems mostly use photovoltaic panels mounted on floats, with multiple floats then connected by plugs or ropes. While both methods allow for the connection of multiple floats, they have certain drawbacks. For example, when using plugs for fixed connections, multiple floats are fixed into a single structure. However, because they are located on the sea surface, waves and currents can impact the fixed floats, causing damage at the connection points and hindering long-term use. When using ropes to connect them, each adjacent float has room to move. While this can solve the problem of damage at the connection points caused by waves and currents, when there are many floats, they will be at various angles. Normally, the photovoltaic panels on the floats are tilted towards the sun. If they are rotated around, they cannot effectively absorb sunlight, reducing power generation efficiency. Summary of the Invention

[0005] In view of the shortcomings of existing technologies, such as damage or low absorption efficiency, the purpose of this invention is to provide a marine photovoltaic floating body connection structure that is not easily damaged and can improve absorption efficiency.

[0006] To solve the above problems, the present invention provides the following technical solution, including: a float for floating on the water surface;

[0007] Mounting components are installed on the float and are used to install photovoltaic panels;

[0008] A connecting component for connecting two adjacent floats;

[0009] A traction assembly is used to connect the float to the connecting assembly, and the traction assembly provides the connecting assembly with a force that moves the float accordingly.

[0010] A positioning element is provided on the float and is used for positioning the connecting assembly, which can be separated from the fixing element;

[0011] When the traction assembly positions the connecting assembly against the positioning member, two adjacent floats are connected via the connecting assembly.

[0012] In some embodiments, the connection component includes a first connector and a second connector;

[0013] The first connector is disposed on the float, and the second connector is disposed on the adjacent float;

[0014] When the two floats approach each other, the first connector and the second connector are fixed to connect the two adjacent floats.

[0015] In some embodiments, the connecting assembly further includes a first magnet, a second magnet, a sleeve, a first rod, a first elastic element, and a groove disposed in the first connector;

[0016] The first magnet is disposed on the first connector, the second magnet is slidably mounted on the second connector, and the sleeve is fitted onto the second connector and fixedly mounted to the second magnet;

[0017] The first rod is inserted into the sleeve, and the first elastic element can pull the first rod to move the first rod into the groove of the first connector;

[0018] When the first connector and the second connector approach each other, the first magnet and the second magnet attract each other. Under the action of attraction, the second magnet drives the sleeve to move towards the first connector until the first rod moves into the groove under the action of the first elastic member, and the first connector and the second connector are fixed.

[0019] In some embodiments, the traction assembly includes a traction member and a second elastic member;

[0020] The second elastic element is disposed within the float body;

[0021] One end of the traction member is connected to the second elastic member, and the other end of the traction member is connected to the first connecting member or the second connecting member corresponding to the float.

[0022] The second elastic element pulls the first connecting element or the second connecting element toward the corresponding float via the traction element.

[0023] In some embodiments, the end face of the positioning member away from the corresponding float is recessed inward, and the traction member passes through the positioning member and connects to the corresponding first connector or second connector.

[0024] When the second elastic member moves the first or second connector closer to the corresponding float via the traction member, the first or second connector is placed in the recess, and the axis of the first or second connector is perpendicular to the corresponding float under the action of the recess.

[0025] In some embodiments, there are multiple traction components and positioning elements on the float, and the number of traction components and positioning elements is the same. The traction components and positioning elements are respectively arranged around the periphery of the float.

[0026] In some embodiments, the mounting element includes a rolling element and a positioning mechanism;

[0027] The rolling element facilitates the moving and installation of the photovoltaic panel;

[0028] The positioning mechanism is used to fix the photovoltaic panel to the floating body.

[0029] In some embodiments, the mounting component further includes a mounting bracket;

[0030] The mounting bracket is mounted on the float, and the rolling element and the positioning mechanism are both mounted on the mounting bracket.

[0031] In some embodiments, the rolling element includes a plurality of pulleys, which are divided into multiple groups on the mounting frame, with the axes of each group of pulleys being coaxial.

[0032] In some embodiments, the positioning mechanism includes a third elastic element, a second rod, and an inclined surface disposed on the second rod;

[0033] The third elastic element can push the second rod to move toward the photovoltaic panel to be installed and insert it into the side of the photovoltaic panel;

[0034] The bevel on the second rod facilitates its insertion into the side of the photovoltaic panel.

[0035] The beneficial effects of this invention are as follows: through the cooperation of the traction component and the positioning component, it can be ensured that when the float is floating on the sea surface, if the water surface does not fluctuate too much, the traction component pulls the connecting component to contact the positioning component, so that there will be no large displacement between multiple floats, ensuring that the photovoltaic panel effectively absorbs light energy and ensuring the efficiency of receiving light energy; when the water surface fluctuates too much, since the connecting component can be separated from the fixing component, the two adjacent photovoltaic panels will not be damaged due to the fixed connection, and it can adapt to the floating of the sea surface more effectively.

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0053] Furthermore, 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 one or more of that feature. In the description of this invention, "multiple" means two or more, unless otherwise explicitly specified.

[0054] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0055] like Figures 1-5As shown, this embodiment provides a marine photovoltaic floating body connection structure, which includes a floating body 110, an mounting component 120, a connecting component 130, a traction component 140, and a positioning component 150. The floating body 110 is used to float on the water surface; the mounting component 120 is installed on the floating body 110 for installing the photovoltaic panel 200; the connecting component 130 is used to connect two adjacent floating bodies 110; the traction component 140 is used to connect the floating body 110 and the connecting component 130, and the traction component 140 provides a force to the connecting component 130 to move towards the corresponding floating body 110; the positioning component 150 is disposed on the floating body 110 for positioning the connecting component 130, and the connecting component 130 can be separated from the fixing component; when the traction component 140 positions the connecting component 130 against the positioning component 150, two adjacent floating bodies 110 are connected via the connecting component 130. In other words, during the installation of offshore photovoltaic systems, the photovoltaic panels 200 are placed on the mounting brackets 120 on the floating bodies 110 to achieve installation. When installing on two adjacent floating bodies 110, the connecting component 130 is first positioned on the positioning bracket 150 under the traction of the traction component 140, making it easy for the two adjacent floating bodies 110 to be positioned and installed via the connecting component 130. Furthermore, with the cooperation of the traction component 140 and the positioning bracket 150, the floating bodies 110 can be kept afloat on the sea surface. If the water surface does not experience excessive movement, the traction component 140 pulls the connecting component 130 into contact with the positioning bracket 150, preventing significant displacement between the multiple floating bodies 110 and ensuring that the photovoltaic panels 200 effectively absorb light energy, thus guaranteeing efficient light reception. When the water surface experiences excessive movement, the connecting component 130 can be separated from the fixing component, preventing damage to the adjacent photovoltaic panels 200 due to fixing, and enabling more effective adaptation to the floating of the sea surface.

[0056] like Figures 3-5 As shown, in this embodiment, the connecting component 130 includes a first connector 131 and a second connector 132. The first connector 131 is disposed on the float 110, and the second connector 132 is disposed on an adjacent float 110. When the two floats 110 approach each other, the first connector 131 and the second connector 132 are fixed to connect the adjacent floats 110. That is, when the two floats 110 approach each other and the first connector 131 and the second connector 132 on the floats 110 come into contact, the connection of the first connector 131 and the second connector 132 can be completed, making the operation simple and convenient.

[0057] like Figures 3-5As shown, in this embodiment, the connecting assembly 130 further includes a first magnet 133, a second magnet 134, a sleeve 135, a first rod 136, a first elastic element 137, and a groove 138 disposed on the first connector 131; the first magnet 133 is disposed on the first connector 131, the second magnet 134 is slidably mounted on the second connector 132, and the sleeve 135 is fitted onto the second connector 132 and fixedly mounted to the second magnet 134; the first rod 136 is inserted into the sleeve 135, and the first elastic element 137... The first rod 136 can be pulled by the component 137 to move the first rod 136 into the groove 138 of the first connector 131; when the first connector 131 and the second connector 132 approach each other, the first magnet 133 and the second magnet 134 attract each other. Under the action of attraction, the second magnet 134 drives the sleeve 135 to move towards the first connector 131 until the first rod 136 moves into the groove 138 under the action of an elastic element, and the first connector 131 and the second connector 132 are fixed. That is, when two adjacent floats 110 approach each other and the first connector 131 and the second connector 132 come into contact, the first magnet 133 on the first connector 131 and the second magnet 134 on the second connector 132 attract each other. Under the action of the attraction, the second magnet 134 moves closer to the first magnet 133 and drives the sleeve 135 to move at the same time until the first rod 136 is placed in the groove 138 under the pull of the first spring. The first connector 131 and the second connector 132 are fixed. No manual operation is required, making the installation more convenient and reducing the installation difficulty.

[0058] Preferably, the first magnet 133 and the second magnet 134 can be neodymium iron boron magnets, alnico magnets, etc., coated with corrosion-resistant coatings, and can be selected according to needs.

[0059] Preferably, the first magnet 133 and the second magnet 134 can also be made of corrosion-resistant samarium cobalt magnets.

[0060] like Figures 4-5As shown, in this embodiment, the traction assembly 140 includes a traction member 141 and a second elastic member 142; the second elastic member 142 is disposed within the float 110; one end of the traction member 141 is connected to the second elastic member 142, and the other end of the traction member 141 is connected to the first connecting member 131 or the second connecting member 132 of the corresponding float 110; the second elastic member 142 pulls the first connecting member 131 or the second connecting member 132 closer to the corresponding float 110 via the traction member 141. That is, one end of the second elastic member 142 is installed inside the float 110, and the other end of the second elastic member 142 is installed with the traction member 141. Under the traction of the second elastic member 142, the first connecting member 131 or the second connecting member 132 is brought into contact with the corresponding positioning member 150 via the traction member 141. This reduces the movement between two adjacent floats 110, ensures that the float 110 does not tilt excessively, and thus ensures the orientation of the float 110, allowing the photovoltaic system to better receive light energy.

[0061] like Figure 6 as well as Figure 8 As shown, in some embodiments, when the seawater is calm, the second elastic element 142 is not separated from the first connector 131 or the second connector 132 and the corresponding float 110.

[0062] like Figure 7 as well as Figure 9 As shown, in some embodiments, when the seawater floats, the first connector 121 and the second connector 132 will separate from the corresponding float 110 under the action of the traction member 141.

[0063] In some embodiments, the traction member 141 is a cable, and its material is a corrosion-resistant material such as ultra-high molecular weight polyethylene, polyester fiber composite material, or synthetic fiber reinforced material. It can be selected according to specific needs, and no specific selection is made here.

[0064] In some embodiments, the number of traction members 141 on each second elastic member 142 is greater than or equal to one.

[0065] Preferably, the optimal number is three or four traction members 141 on each of the second elastic members 142.

[0066] like Figures 4-5As shown, in this embodiment, the end face of the positioning member 150 away from the corresponding float 110 is recessed inward, and the traction member 141 passes through the positioning member 150 and is connected to the corresponding first connector 131 or second connector 132; when the second elastic member 142 moves the first connector 131 or second connector 132 closer to the corresponding float 110 via the traction member 141, the first connector 131 or second connector 132 is placed in the recess, and under the action of the recess, the axis of the first connector 131 or second connector 132 is perpendicularly pointed to the corresponding float 110. By adopting a recessed design, the corresponding first connector 131 or second connector 132 can be placed and limited within the recess under the traction of the traction member 141. This prevents the lack of positioning of the first connector 131 or second connector 132 from affecting the alignment and fixation of the first connector 131 and second connector 132. At the same time, it can also prevent the lack of positioning of the first connector 131 or second connector 132 from causing the adjacent two floats 110 to deflect during use, thereby affecting the photovoltaic panel 200's reception of light energy.

[0067] In some embodiments, the concave shape is hemispherical.

[0068] like Figures 3-5 As shown, in this embodiment, there are multiple traction components 140 and positioning members 150 on the float 110, and the number of traction components 140 and positioning members 150 is the same. The traction components 140 and positioning members 150 are respectively arranged around the float 110. By setting the traction components 140 and positioning members 150 around the float 110, that is, by setting the first connecting member 131 or the second connecting member 132 around the float 110, it is convenient to connect multiple floats 110 to each other.

[0069] In one embodiment, the first connector 131 and the second connector 132 can be respectively disposed opposite to a float 110, so that any two floats 110 can be connected.

[0070] In another embodiment, the first connector 131 and the second connector 132 can be separately provided on a float 110, and the float 110 provided with the first connector 131 and the float 110 provided with the second connector 132 can be installed sequentially.

[0071] like Figures 1-2As shown, in this embodiment, the mounting component 120 includes a rolling element 121 and a positioning mechanism 122. The rolling element 121 facilitates the moving installation of the photovoltaic panel 200; the positioning mechanism 122 is used to fix the photovoltaic panel 200 to the float 110. By using the rolling element 121, after the photovoltaic panel 200 is placed on the rolling element 121, it can be quickly moved to the designated installation position by simply pushing the rolling element 121, reducing the difficulty of manual adjustment. Furthermore, the positioning mechanism 122 can fix the photovoltaic panel 200 after it has moved to the designated position, preventing the photovoltaic panel 200 from easily detaching from the float 110.

[0072] like Figures 1-2 As shown, in this embodiment, the mounting component 120 further includes a mounting frame 123; the mounting frame 123 is mounted on the float 110, and the rolling element 121 and the positioning mechanism 122 are both mounted on the mounting frame 123. The mounting frame 123 can effectively support the photovoltaic panel 200.

[0073] like Figure 1 As shown, in this embodiment, there is an angle between the photovoltaic panel 200 and the floating body 110, which ensures that the photovoltaic panel 200 faces the sun after installation and receives light energy more effectively.

[0074] like Figure 1 As shown, in this embodiment, the rolling element 121 includes multiple pulleys 121a, which are divided into multiple groups on the mounting frame 123, with the axes of each group of pulleys 121a being coaxial. The multiple pulleys 121a provide support for the photovoltaic panel 200 after it is placed in the mounting frame, facilitating the rolling adjustment of the photovoltaic panel 200.

[0075] like Figure 2 as well as Figure 10 As shown, in this embodiment, the positioning mechanism 122 includes a third elastic element 122a, a second rod 122b, and an inclined surface on the second rod 122b. The third elastic element 122a can push the second rod 122b to move towards the photovoltaic panel 200 to be installed and insert it into the side of the photovoltaic panel 200. The inclined surface on the second rod 122b facilitates the insertion of the second rod 122b into the side of the photovoltaic panel 200. That is, under the action of the inclined surface, when the photovoltaic panel 200 is placed, the second rod 122b promptly makes way, and after the photovoltaic panel 200 moves to the designated position, the second rod 122b, under the pulling force of the third elastic element 122a, inserts into the side of the photovoltaic panel 200 to fix the photovoltaic panel 200. The operation is simple and convenient.

[0076] Preferably, the first elastic element 137, the second elastic element 142 and the third elastic element 122a are springs, and the springs are made of corrosion-resistant materials such as stainless steel and nickel-based alloys. The selection is made according to the requirements and no specific requirements are made here.

[0077] In summary, this invention provides a connection structure for marine photovoltaic floating bodies. Through the cooperation of the traction component and the positioning component, it can ensure that when the floating body is floating on the sea surface, if the water surface does not fluctuate excessively, the traction component pulls the connecting component into contact with the positioning component, preventing significant displacement between multiple floating bodies and ensuring that the photovoltaic panels effectively absorb light energy and guarantee the efficiency of light energy reception. When the water surface fluctuates excessively, since the connecting component can be separated from the fixing component, adjacent photovoltaic panels will not be damaged due to the fixed connection, thus more effectively adapting to the floating of the sea surface.

[0078] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
