Description

Technical Field

[0001] The present invention relates to the field of floating photovoltaics, and particularly to a method for manufacturing a floating body that prevents cavities from appearing in the pull tabs of the floating body during the blow molding process. Background Art

[0002] Solar energy is a clean energy source. Utilizing a photovoltaic power station to directly convert solar energy into electrical energy is an efficient way to utilize solar energy. Floating photovoltaics refers to the construction of a photovoltaic power station using idle water surfaces. Floating photovoltaic power stations have many advantages such as not occupying land resources, reducing water evaporation, and avoiding algae growth, and have broad development prospects.

[0003] A floating photovoltaic power station uses a floating body array to carry solar panels. Currently, such floating photovoltaic power stations are mostly constructed and implemented on the water surfaces of inland waters such as lakes and rivers. Due to the complex marine environment, there are often large winds and waves, resulting in violent fluctuations on the sea surface. Even in the offshore sea area, the floating bodies of the floating photovoltaic array often break, thus affecting the stability of the entire floating photovoltaic array. Currently, the available inland water surfaces for the construction of floating photovoltaic power stations are gradually decreasing. Utilizing the vast sea areas in the offshore and even the open sea to build floating photovoltaic power stations, provide clean energy, reduce carbon emissions, and contribute to "carbon peak" and "carbon balance" is an important future development direction in this field. For areas with complex environments, there are often winds and waves, and there will be fluctuations between adjacent floating bodies. During the fluctuation process, mutual forces will be generated between adjacent pull tabs, and the pull tabs of the floating body are easily broken. Summary of the Invention

[0028] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0029] In the following detailed description, reference may be made to the various specification drawings that form a part of this application and illustrate specific embodiments of the application. In the drawings, like reference numerals generally describe substantially similar components in different figures. The specific embodiments of the present application are described in sufficient detail below to enable those of ordinary skill in the art with relevant knowledge and technology to implement the technical solutions of the present application. It should be understood that other embodiments may also be utilized or structural, logical or electrical changes may be made to the embodiments of the present application.

[0030] Wave floating body array

[0031] The present disclosure provides a novel floating body array resistant to wind and wave fluctuations. Each floating body in the floating body array can fluctuate following the undulation of the water surface waves, reducing the impact of the waves on the floating body array, avoiding loosening between the floating bodies, making the structure of the floating body array more stable, and enabling better adaptation to the harsh natural environment at sea.

[0032] The technical solution of the present application will be further described below through specific embodiments. Those skilled in the art should understand that the following description is only for the convenience of understanding the technical solution of the present application and should not be used to limit the protection scope of the present application.

[0033] Figure 1A and Figure 1B is a schematic structural diagram of a floating body array according to an embodiment of the present application; wherein, Figure 1A is a top view of the floating body array, Figure 1B is a side view of the floating body array. As shown in the figure, the floating body array 100 includes: a plurality of first floating bodies 110, a plurality of second floating bodies 120, and a plurality of movable connections 130. The plurality of second floating bodies 120 are connected to the plurality of first floating bodies 110 to form the entire floating body array. The first floating bodies 110 are used to carry solar panels. Of course, the second floating bodies 120 can be used to carry solar panels or for other purposes, such as forming channels in the floating body array, carrying cables or other electrical equipment, carrying auxiliary facilities such as fences, etc.

[0034] The plurality of movable connections 130 are arranged in one or more of between the first floating bodies, between the second floating bodies, and between the first floating bodies and the second floating bodies. The movable connection allows the connected plurality of first floating bodies and / or second floating bodies to change their relative positions in the vertical direction. When waves come (refer to Figure 1C ), some of the first floating bodies and / or second floating bodies can be at the wave crest, and some of the first floating bodies and / or second floating bodies can be at the wave trough. The entire floating body array can fluctuate following the undulation of the waves, thereby reducing the impact of the waves on the structure of the floating body array. Compared with a floating body array with fixed connections between the floating bodies, the connections between the floating bodies of the floating body array of the present invention are not easily loosened, the structure is more stable, and it can withstand larger levels of wind and waves, thus being able to adapt to harsher natural environments at sea.

[0035] In some embodiments, referring to FIG. 1, the first floating body 110 may be a main floating body and can be used to carry a solar panel (or a solar cell panel). The second floating body 120 may be a connecting floating body that is connected between the first floating bodies 110. It can space apart multiple first floating bodies 110, so as to facilitate the setting of solar panels on the first floating bodies 110 and space apart the solar panels to prevent collision interference. In some embodiments, the floating body array may further include other types of floating bodies. For example: it includes a plurality of third floating bodies, and the third floating bodies may be disposed in one or more of between the first floating bodies, between the second floating bodies, and between the first floating body and the second floating body, and are movably connected to the first floating body and / or the second floating body.

[0036] In some embodiments, the movable connection 130 may include a connecting member. The connected first floating body and / or second floating body may be respectively connected to the connecting member and can each move vertically along the connecting member, thereby changing the relative position. As understood by those skilled in the art, the connecting member may be a slide bar, a rivet, a screw, a linear bearing, etc.

[0037] In some embodiments, the movable connection 130 allows the connected plurality of first floating bodies and / or second floating bodies to change their relative positions within a certain range in the vertical direction. The amount of change in the relative position may include a first range R1. Within the first range R1, the connected plurality of first floating bodies and / or second floating bodies can freely change their relative positions. The size of the first range R1 may be related to the surface area of the first floating body. For example: the larger the surface area of the first floating body, the greater the waves it bears, and the larger the first range R1; vice versa. In some embodiments, the size of the first range R1 may be less than or equal to 20 cm; or less than or equal to 15 cm; or less than or equal to 10 cm; or less than or equal to 5 cm; or less than or equal to 3 cm.

[0038] In some specific embodiments, the connecting member may include an upper stop and a lower stop. Among them, the first range R1 is defined between the upper stop and the lower stop, and the first floating body and / or the second floating body can move freely between the upper stop and the lower stop, so that the first floating body and / or the second floating body can freely change their relative positions in the vertical direction.

[0039] In some embodiments, the amount of change in the relative position of the connected plurality of first floating bodies and / or second floating bodies allowed by the movable connection 130 may further include a second range R2. The second range R2 is greater than the first range R1. Between the first range R1 and the second range R2, the movement of the connected plurality of first floating bodies and / or second floating bodies to change their relative positions is subject to resistance. In some embodiments, between the first range R1 and the second range R2, the resistance experienced by the movement of the connected plurality of first floating bodies and / or second floating bodies to change their relative positions increases as it approaches the upper and / or lower boundaries of the second range R2. In other words, the closer the first floating body and / or the second floating body is to the boundary of the second range R2, the greater the resistance to the relative movement they experience.

[0040] In some specific embodiments, the upper stop may include a ramp, and the diameter of the side closer to the lower stop is smaller than that of the side farther from the lower stop. The connected first floating body and / or second floating body can move along the side of the upper stop closer to the lower stop toward the side farther from the lower stop, and the resistance experienced by the first floating body and / or the second floating body gradually increases during the movement along the upper stop.

[0041] To facilitate a further understanding of the technical solution of the present application, the implementation manner of the movable connection will be further described in detail below through a specific example.

[0042] Figure 2A and Figure 2B FIG. is a schematic diagram of the connection between the first floating body and the second floating body according to an embodiment of the present application. As shown in the figure, the first floating body 110 and / or the second floating body 120 are connected together through a movable connection 130. The movable connection 130 between the first floating body 110 and / or the second floating body 120 may include a connecting member 200, which can connect the first floating body 110 and the second floating body 120. The first floating body 110 and / or the second floating body 120 can move independently on the connecting member 200 to change their relative positions.

[0043] In some embodiments, the connecting member 200 may include a through member 210 and a sealing end member 220. The sealing end member 220 is the upper stop. The first lug and the second lug include holes for the through member 210 to pass through. The through member 210 passes through the first lug of the first floating body 110 and the second lug of the second floating body 120. The first lug and the second lug do not have threads. The sealing end member 220 is disposed on the through member and can prevent the first lug and / or the second lug from detaching from the through member. In some embodiments, the connecting member 200 may further include a locking member 230, which can be disposed on the through member and can be used to lock the position of the sealing end member to prevent it from detaching from the through member 210, thereby disconnecting the first floating body and the second floating body.

[0044] In some embodiments, the through member 210 may include a stop head 211. The stop head 211 is the lower stop member. The stop head 211 cooperates with the end sealing member 220 to define the positions of the first lugs of the first floating body and the second lugs of the second floating body, so that the first floating body and the second floating body can be connected. In some embodiments, the distance between the stop head 211 and the end sealing member 220 may be a first range R1. The size of the first range R1 is greater than the thicknesses of the first lug and the second lug, so that the first lug and / or the second lug can move freely within a certain range between the stop head 211 and the end sealing member 220.

[0045] Figure 3 FIG. is a schematic diagram of the connection between the first floating body and the second floating body according to another embodiment of the present application. As shown in the figure, the first floating body 110 and / or the second floating body 120 are connected together by a movable connection 130. The movable connection 130 may include a connecting member 300 that connects the first floating body 110 and the second floating body 120. The first floating body 110 and / or the second floating body 120 can move independently on the connecting member 300 to change their relative positions.

[0046] In some embodiments, the connecting member 300 may include a through member 310 and an end sealing member 320. The through member 310 passes through the first lug of the first floating body 110 and the second lug of the second floating body 120. The end sealing member 320 is disposed on the through member and can prevent the first lug and the second lug from detaching from the through member. In some embodiments, the connecting member 300 may further include a locking member 330 for locking the position of the end sealing member to prevent it from detaching from the through member 310. In some embodiments, the through member 310 may include a stop head 311. In some embodiments, the distance between the stop head 311 and the end sealing member 320 may be a first range R1. Within the first range R1, the first lug and the second lug move freely. The other structures of the through member 310 are similar to those of the through member 210 in the embodiment of FIG. 2, so they will not be described in detail here.

[0047] In some embodiments, the end sealing member 320 has a gradually increasing diameter from bottom to top to form an inclined surface 321. The diameters of the holes of the first lug and the second lug are greater than the minimum diameter of the lower end of the end sealing member 320, so that they can move at least on part of the inclined surface 321. When the first lug and the second lug move upward along the inclined surface 321, they will start to be resisted as the diameter of the end sealing member gradually increases, and the resistance becomes greater the farther away from the stop head. In other words, the movement range of the first lug and / or the second lug includes a second range R2. When the first lug and / or the second lug move within the second range greater than the first range, they will be resisted, and the resistance increases as they approach the boundary of the second range. In some embodiments, the end sealing member 320 may be a ramp nut. In some embodiments, the other structures of the end sealing member 320 are similar to those of the end sealing member 220 in the embodiment of FIG. 2, so they will not be described in detail here.

[0048] Figure 4A and Figure 4B is a schematic diagram of a through - piece according to an embodiment of the present application. As shown in the figure, the through - piece 400 includes a stop head 410 and a through - rod 420. Among them, the through - rod 420 is connected to the stop head 410 and can extend outward from the stop head 410 to pass through the holes of the first lug and the second lug, connecting the first lug and the second lug. The stop head 410 can block the first lug and / or the second lug, and cooperate with the end - sealing member to define the positions of the first lug and the second lug. In some embodiments, the stop head 410 and the through - rod 420 can be integrally formed. In some embodiments, the through - piece can be injection - molded from a polymer elastomer. In some embodiments, the polymer elastomer can be plastic, rubber, elastic resin, etc. In some embodiments, the material of the through - piece can be the same as the material of the floating body. In some embodiments, the through - piece can be a bolt.

[0049] In some embodiments, the side of the stop head 410 away from the through - rod 420 can include a plurality of reinforcing members 411, which can be used to increase the strength of the stop head. In some embodiments, the reinforcing members 411 can be a combination of a reinforcing ring and a plurality of reinforcing strips. As understood by those skilled in the art, the reinforcing member 410 can also be other forms of reinforcing structures.

[0050] In some embodiments, the outer surface of at least one end of the through - rod 420 away from the stop head includes an external thread, which can be used to connect the through - piece to the end - sealing member. In some embodiments, the through - rod 420 can also include an opening 421, which can be used to accommodate a locking member disposed on the through - piece. In some embodiments, the locking member can be a rod, bar, pin or stick, etc. By inserting into the opening 421, the end - sealing member can be locked. In some embodiments, the opening 421 can penetrate the through - rod 420, and the locking member can directly penetrate the through - rod 420 to provide connection stability. In some embodiments, the distance between the opening 421 and the stop head can be 60mm - 115mm. For example: it can be 61.5mm, 76.5mm, 102mm, etc.

[0051] In some embodiments, the through - rod 420 can include a hollow chamber 422, so as to facilitate faster cooling during the injection - molding process of the through - piece, improve processing efficiency, and have better finished - product quality control. Moreover, it can also save production materials and costs.

[0052] The first lug and / or the second lug can move on the connecting member. As understood by those skilled in the art, the friction on the through - piece will increase. In some embodiments, the surface of the through - piece in contact with the first lug and / or the second lug can include a wear - resistant design, so as to increase the service life of the through - piece and improve the stability of the floating - body array.

[0053] Figure 5 Schematic structural diagram of an end piece according to an embodiment of the present application. As shown in the figure, the end piece 500 includes an opening 510 provided with internal threads. The end piece can be arranged on the through rod of the through member by means of thread engagement, so as to cooperate with the stop head of the through member to block and limit the first ear and / or the second ear on the through rod.

[0054] In some embodiments, the end piece 500 may further include a contact plate 520 and a connection plate 530. Among them, the contact plate 520 is perpendicularly connected to the connection plate 530, and the contact plate 520 is close to the first ear or the second ear, and the connection plate 530 is connected to the through rod. In some embodiments, the end piece 500 may further include a plurality of reinforcing plates 540, which are vertically connected at intervals between the contact plate 520 and the connection plate 530, which can increase the connection strength between the contact plate and the connection plate and improve the overall strength of the end piece. In some embodiments, the shape of the reinforcing plate 540 may be trapezoidal, and the width of the reinforcing plate gradually becomes wider from the side close to the contact plate to the side far from the contact plate, so that the end piece forms an inclined surface, which is beneficial to the movement of the first ear and / or the second ear on the end piece.

[0055] In some embodiments, one or more grooves 521 are included on the side of the connection plate 530 away from the contact plate 520, which can be used to accommodate locking members, so as to lock the end piece on the through rod and prevent the end piece from rotating relative to the through rod. In some embodiments, the grooves 521 may be arranged at intervals between a plurality of reinforcing plates. In some embodiments, the end piece may be injection molded from a polymer elastomer. In some embodiments, the polymer elastomer may be plastic, rubber, elastic resin, etc. In some embodiments, the material of the end piece may be the same as the material of the floating body. In some embodiments, the end piece may also be a nut.

[0056] The first ear and / or the second ear can move on the connecting member. As understood by those skilled in the art, the friction received by the end piece will increase. In some embodiments, the surface of the end piece in contact with the first ear and / or the second ear may include a wear-resistant design, so as to increase the service life of the end piece and improve the stability of the floating body array.

[0057] For the fluctuating floating body array of the present invention, the impact received by the movable connection will be more frequent. The shear force received by the connecting member will increase accordingly. Similarly, the force received by the floating body ear will also increase. The present application also includes further improvements to the connecting member and the floating body ear to increase the stability of the fluctuating floating body array. This will be described in detail through specific examples below.

[0058] Connector reinforcement

[0059] In a floating body array, adjacent floating bodies are connected to the through members of the connecting member. As the adjacent floating bodies follow the movement of the water surface waves, shear forces will be applied to the through members. As the distance between the floating bodies increases, the shear force acting on the through members also increases accordingly. Therefore, the improvement scheme of the through members is introduced in detail below to increase the shear resistance.

[0060] Figure 6 FIG. is a schematic diagram of a through member according to an embodiment of the present application. As shown in the figure, the through member 600 includes a stop head 610 and a through rod 620. Among them, the through rod 620 is connected to the stop head 610 and can extend outward from the stop head 610 to pass through the holes in the first lug and the second lug, connecting the first lug and the second lug, similar to the embodiment of FIG. 4.

[0061] In some embodiments, the through member 600 further includes a support member 630, which can be disposed in the hollow chamber of the through rod 620, which can increase the shear resistance of the through member. In some embodiments, the position of the support member disposed in the hollow chamber overlaps with the positions where the first lug and the second lug contact the through rod. In other words, the height of the support member is at least greater than the distance between the two farthest sides of the first lug and the second lug. Thus, the shear force of the first floating body and the second floating body on the through member during the floating process can be resisted. In some embodiments, the height of the support member does not exceed the perforation of the through rod to avoid blocking the perforation, so that the locking member cannot be inserted into the perforation. In some embodiments, the support member 630 can be made of rigid materials. For example: metals or alloys, ceramics, carbon fibers, etc.

[0062] In some embodiments, the through rod 620 may further include a core (not shown in the figure), which can be disposed in the hollow chamber of the through rod 620 and can be used to sleeve the support member 630. For example, the core can be disposed at the center of the hollow chamber, and the support member 630 can be directly sleeved on the core and thus disposed in the hollow chamber. In some embodiments, the shape of the core can be conical to facilitate the sleeving of the support member. In some embodiments, the material of the core can be a polymer elastomer material. In some embodiments, the core can extend outward from the stop head and can be integrally formed with the stop head.

[0063] In some embodiments, the through rod 620 may further include one or more protrusions (not shown in the figure), which can be disposed on the inner wall of the hollow chamber of the through rod 620 and protrude into the hollow chamber, and can be used to snap-fit the support member 630. In some embodiments, the support member 630 may correspondingly include one or more grooves for snap-fitting with the protrusions. In some embodiments, the protrusions can cooperate with the stop head to snap-fit the support member 630 in the hollow chamber. In some embodiments, the protrusions can be integrally formed with the inner wall of the hollow chamber.

[0064] In some embodiments, the support member can also be disposed in the hollow chamber by using a sealing member. In some embodiments, the through rod 620 can include one or more through grooves (not shown in the figure), which extend from the side away from the stop head towards the stop head side and communicate with the hollow chamber. The side wall of the hollow chamber can slightly expand outward from the hollow chamber to facilitate the setting of the support member in the hollow chamber. In some embodiments, the groove is disposed on at least a part of the through rod. For example, it is arranged at one end away from the stop head, so that the side wall of the hollow chamber at the end away from the stop head can be expanded outward, facilitating the support member to enter the hollow chamber. By using a sealing member with a diameter smaller than that of the through rod, the side wall of the hollow chamber including the groove part can be restricted to contract towards the inside of the hollow chamber, so that the support member can be enclosed in the hollow chamber.

[0065] As understood by those skilled in the art, the through member can also include other strengthening methods. The present application also provides other solutions for increasing the shear resistance of the through member.

[0066] Figure 7 FIG. is a schematic diagram of a through member according to another embodiment of the present application. As shown in the figure, the through member 700 includes a stop head 710 and a through rod 720. Among them, the through rod 720 is connected to the stop head 710 and can extend outward from the stop head 710 to pass through the holes of the first lug and the second lug to connect the first lug and the second lug, which is similar to the through member in the embodiment of FIG. 4.

[0067] In some embodiments, the thickness of the side wall of the hollow chamber of the through rod 720 is stepped. The closer to the stop head side, the thicker the thickness, so as to increase the strength of the through rod and improve the shear resistance of the through member. In some embodiments, the position where the side wall of the hollow chamber is the thickest overlaps with the positions where the first lug and the second lug contact the through rod. In other words, the height of the thickest position of the side wall is at least greater than the distance between the two farthest sides of the first lug and the second lug. Thus, the shear force on the through member during the floating process of the first floating body and the second floating body can be resisted.

[0068] Figure 8 FIG. is a schematic diagram of a through member according to another embodiment of the present application. As shown in the figure, the through member 800 includes a stop head 810 and a through rod 820. Among them, the through rod 820 is connected to the stop head 810 and can extend outward from the stop head 810 to pass through the holes of the first lug and the second lug to connect the first lug and the second lug, which is similar to that in the embodiment of FIG. 4.

[0069] In some embodiments, the through member 800 further includes a support layer 830, which can be disposed on the outer sidewall of the through rod 820, and can increase the shear resistance of the through member. In some embodiments, the position where the support layer is disposed on the outer sidewall overlaps with the positions where the first lug and the second lug contact the through rod. In other words, the height of the support layer is not less than the distance between the two farthest sides of the first lug and the second lug. Thereby, the shear force on the through member during the floating process of the first floating body and the second floating body can be resisted. In some embodiments, the height of the support layer does not exceed the perforation of the through rod to avoid blocking the perforation, so that the locking member cannot be inserted into the perforation. In some embodiments, the support layer 830 can be a rigid material. For example: metal or alloy, ceramic, carbon fiber, etc.

[0070] In some embodiments, the outer sidewall of the through rod 820 may further include a groove (not shown in the figure), which can be used to accommodate the support layer, so that the overall outer surface of the through rod is flat, facilitating the connection of the first lug and / or the second lug, and facilitating the movement of the position of the first lug and / or the second lug. In some embodiments, the depth of the groove can be the same as or slightly larger than the thickness of the support layer. In some embodiments, the support layer can be expanded by heating and then sleeved into the groove of the through rod, and cooled to shrink the support layer and tightly fit it in the groove of the through rod to complete the assembly of the support layer. In some embodiments, the support layer can be pre-installed on the through member when it leaves the factory.

[0071] In some embodiments, the through member 800 further includes a buffer layer 840, which can be disposed outside the support layer and wrap the support layer, can buffer the acting force generated when the first lug and / or the second lug moves, and can also protect the support layer (such as rust prevention, corrosion prevention, etc.). In some embodiments, the buffer layer 830 can be a film, cloth, plastic, rubber, etc. In some embodiments, the buffer layer can be pasted on the outer side of the support layer by pasting to protect the support layer.

[0072] The through member of the present application can greatly improve its shear resistance by using the above strengthening methods, thereby increasing the service life of the through member and ensuring the stability of the floating body array. Of course, as understood by those skilled in the art, the strengthening methods of the through member of the present application can use one or a combination of the above.

[0073] Figure 9Anti-shear flow chart for the connection between floating pontoons according to an embodiment of the present application. As shown in the figure, in step 910, adjacent pontoons are connected using a connecting member including a hollow chamber. In some embodiments, the connecting member may include a through member and an end cap member. In some embodiments, adjacent pontoons can be sleeved on the through member, and then the end cap member is installed on the through member, thereby connecting adjacent pontoons. In some embodiments, the through member may include a hollow chamber, which is conducive to rapid cooling during the injection molding process of the through member, improving the yield rate and saving raw materials. In some embodiments, the material of the through member can be a polymer elastomer. For example: plastics, rubbers, elastic resins, etc. In some embodiments, the material of the connecting member can be the same as that of the pontoon.

[0074] In some embodiments, the connecting member may include a buffer layer at the position where it contacts the adjacent pontoon, thereby buffering the force generated during the floating process of the adjacent pontoon. In some embodiments, below the buffer layer at the position where the connecting member contacts the adjacent pontoon, a support layer may further be included, thereby improving the strength and anti-shear ability of the connecting member, extending the service life of the connecting member, and increasing the stability of the pontoon array.

[0075] In step 920, a support member is placed in the hollow chamber of the connecting member. In some embodiments, the position of the support member coincides with the contact position between the adjacent pontoon and the connecting member, thereby resisting the shear force of the adjacent pontoon floating. In some embodiments, the hollow chamber may include a core made of a polymer elastomer material, and the support member can be sleeved on the core and arranged in the hollow chamber. In some embodiments, the support member can be enclosed in the hollow chamber using an end cap member. In some embodiments, the through member includes an outwardly supported side wall, and this side wall forms a hollow chamber. In other words, one or more grooves are included on the side wall of the through member, which can cause the side wall of the through member to expand slightly outward, facilitating the setting of the support member in the hollow chamber. In some embodiments, an end cap member with a size slightly smaller than the through member can be arranged on the through member, thereby restricting the outwardly supported side wall, contracting it inward, and limiting the support member. In some embodiments, the support member can be pre-set in the hollow chamber. For example: before the through member leaves the factory. In some embodiments, the material of the support member is a rigid material. For example: metals or alloys, ceramics, carbon fibers, etc.

[0076] Floating body lug reinforcement

[0077] In a pontoon array, the connection between adjacent pontoons needs to be made through the lugs of the adjacent pontoons. In areas with complex environments, there are often winds and waves, and there will be fluctuations between adjacent pontoons. During the fluctuation process, mutual forces will be generated between adjacent lugs, and the pontoon lugs are easily broken. Therefore, the following will introduce in detail the improvement scheme of the pontoon lugs to increase the strength of the lugs.

[0078] Figure 10A and Figure 10B is a schematic diagram of a floating body according to an embodiment of the present application. As shown in the figure, the floating body 1000 includes a main body 1010 and one or more lugs 1020. Among them, the one or more lugs 1020 extend outward from the main body 1010 and can be used for connection between adjacent floating bodies. In some embodiments, the lugs 1020 may extend outward from the corners or positions near the corners of the main body 1010. In some embodiments, 8 lugs are respectively arranged on two sides of the floating body 1000 connected to other floating bodies. Every 2 lugs are used to connect to one other floating body. Specifically, each set of 2 lugs includes a first lug 1021 arranged at the corner of the floating body 1000 and extending outward from the main body, and a second lug 1022 arranged on the side of the floating body 1000. The second lug 1022 is close to the first lug 1021 but spaced apart from the first lug 1021. In some embodiments, the floating body 1000 may not include the second lug, and the floating body 1000 is only connected to other floating bodies through the first lugs. In some embodiments, the lugs 1020 and the main body 1010 may be integrally formed. In some embodiments, the floating body 1000 is made by blow molding.

[0079] In some embodiments, the floating body 1000 may further include one or more supports 1030, which can be used to connect to a bracket, so as to support a solar panel fixed to the bracket. In some embodiments, the support 1030 may be located on the lugs at the corners of the main body. In some embodiments, the support 1030 may also be located at other positions. For example: on the main body 1010. In some embodiments, the material of the floating body 1000 may be high-density polyethylene material, which has high strength, good toughness and durability.

[0080] In some embodiments, the main body 1010 is similar to the main bodies of existing floating bodies. The technical solution of the present application is mainly to increase the strength of the lugs, so the main body structure will not be described in detail here.

[0081] Further, referring to Figure 10B , the lugs 1020 are integrally formed with the main body and naturally extend outward from the main body. The lug includes an ear plate 1023 and a through hole 1024 is provided on the ear plate, so that connecting pieces such as bolts can pass through. In order to increase the strength of the lugs, a strengthening structure may also be provided on the ear plate.

[0082] In some embodiments, the reinforcement structure may include a first reinforcement edge 1001 and a second reinforcement edge 1002. The first reinforcement edge 1001 is arranged on both sides of the ear plate and is arranged around the through hole 1024, and the second reinforcement edge 1002 is arranged on both sides of the ear plate and is arranged around the edge of the ear, so that the thickness of the ear plate can be increased and the strength of the ear plate can be improved. In some embodiments, the reinforcement structure may also include a reinforcement ring 1003, which is arranged on both sides of the ear plate and is located between the first reinforcement edge 1001 and the second reinforcement edge 1002, and divides the ear plate into a first area and a second area, wherein the first area is the area between the first reinforcement edge and the reinforcement ring, and the second area is the area between the second reinforcement edge and the reinforcement ring. In some embodiments, the shape of the reinforcement ring 1003 is the same as the shape of the first reinforcement edge and / or the through hole. In some embodiments, in the arc portion of the pull ear, the first reinforcement edge and the second reinforcement edge are at the same distance from the reinforcement ring.

[0083] In some embodiments, the reinforcement structure may further include a plurality of reinforcement strips 1004, which are arranged in the first area and the second area, so as to increase the strength of the ear plate. In some embodiments, the reinforcement strips are arranged in the first area and the second area in a divergent shape. Among them, the reinforcement strips in the first area connect the reinforcement ring and the first reinforcement edge, and the reinforcement strips in the second area connect the reinforcement ring and the second reinforcement edge. In some embodiments, the positions of the reinforcement strips in the first area and the reinforcement strips in the second area on the reinforcement ring do not overlap, in other words, the reinforcement strips in the first area and the reinforcement strips in the second area are not connected on the reinforcement ring. This can prevent the uneven distribution of raw materials caused by the concentration of raw materials during the blow molding of the ear plate, and the appearance of cavities in the pull ear. As understood by those skilled in the art, the buoyant body floats with the water surface during use, and the adjacent ear plates are in a state of friction for a long time. If the pull ear cavity appears, it is very easy to be damaged and ruptured, which will cause the buoyant body to leak air and affect the use of the buoyant body.

[0084] In some embodiments, the first region reinforcement strips and / or the second region reinforcement strips are arranged at the same spacing on the reinforcement ring. That is, the reinforcement strips are arranged at equal spacing on the reinforcement ring. In some embodiments, the first region reinforcement strips and the second region reinforcement strips are staggered and connected to the reinforcement ring. In some embodiments, the first region reinforcement strips and / or the second region reinforcement strips can also be arranged in other ways. For example, they are arranged crosswise with the current reinforcement strips.

[0085] In some embodiments, the pull ear 1020 may further include a wear-resistant support layer (not shown in the figure), which may be disposed on both sides of the ear plate and completely cover the reinforcement structure of the ear plate, and may cover the pull ear, thereby preventing the pull ear from being damaged and broken during use after a cavity appears, and may protect the pull ear. In some embodiments, the wear-resistant support layer may be a rigid material, thereby further improving the strength of the pull ear. In some embodiments, the rigid material may be a metal or alloy, ceramic, carbon fiber, etc.

[0086] In some embodiments, the lug 1020 may further include a support core (not shown in the figure), which is disposed in the ear plate and may be connected to the main body 1010, thereby increasing the strength of the lug. In some embodiments, the shape of the support core may be the same as that of the ear plate and / or the through hole, so that the support core is uniformly stressed during the use of the lug. In some embodiments, the support core may be a rigid material. For example: metal or alloy, ceramic, carbon fiber, etc.

[0087] Figure 11 FIG. is a flowchart of a method for manufacturing a floating body according to an embodiment of the present application. In step 1110, a first channel surrounding the lug connection hole is provided in the lug portion of the floating body mold. In some embodiments, when the raw material for manufacturing the floating body enters the first channel in the lug portion of the floating body mold, a first reinforcing edge protruding from the lug ear plate may be formed.

[0088] In step 1120, a second channel surrounding the lug edge is provided in the lug portion of the floating body mold. In some embodiments, when the raw material for manufacturing the floating body enters the second channel in the lug portion of the floating body mold, a second reinforcing edge protruding from the lug ear plate may be formed.

[0089] In step 1130, an annular channel is provided in the lug portion of the floating body mold, and the annular channel is located between the first channel and the second channel, dividing the ear plate portion into a first region and a second region. In some embodiments, when the raw material for manufacturing the floating body enters the annular channel in the lug portion of the floating body mold, a reinforcing ring protruding from the lug ear plate may be formed.

[0090] In step 1140, radial bars are provided in the first region and the second region of the lug portion of the floating body mold. In some embodiments, when the raw material for manufacturing the floating body enters the radial bars in the lug portion of the floating body mold, reinforcing bars protruding from the lug ear plate may be formed. In some embodiments, the radial bars in the first region are not connected to the radial bars in the second region at the annular channel, so that the reinforcing bars on the lug ear plate are not connected on the reinforcing ring.

[0091] In some embodiments, in the ear portion of the floating body mold, a support core is disposed between the floating body molds. In some embodiments, when the raw material for making the floating body enters the ear portion of the floating body mold, the support core can be wrapped, so that the support core can be disposed in the floating body ear. In some embodiments, the shape of the support core is similar to the shape of the floating body ear, and also has through holes to facilitate the connection of adjacent floating bodies. In some embodiments, the support core can extend into the main body portion of the floating body mold, so that the raw material of the main body portion can also wrap part of the support core, and the support core can be connected to the main body portion of the floating body. In some embodiments, the distance between the support core and the floating body molds on both sides is the same, so that the support core can be disposed in the middle of the ear to ensure the strength of the ear. In some embodiments, the material of the support core is different from the material of the floating body.

[0092] In some embodiments, in the ear portion of the floating body mold, a wear-resistant support layer is disposed on the floating body mold. In some embodiments, when the raw material for making the floating body enters the ear portion of the floating body mold, the wear-resistant support layer can be thermoset with the heated raw material, so that the wear-resistant support layer can be disposed on the surface of the floating body ear. In some embodiments, the shape of the wear-resistant support layer can be exactly the same as that of the ear portion of the floating body mold, so that it can be completely attached to the ear portion of the floating body mold and can also be completely attached to the floating body ear. In some embodiments, the wear-resistant support layer can be pre-pasted in the floating body mold. In some embodiments, the material of the wear-resistant support layer is different from the material of the floating body.

[0093] The floating body ear of the present application can greatly improve the strength and wear resistance of the ear through the strengthening structure, the internal support core and the external wear-resistant support layer, thereby increasing the service life of the floating body ear. Moreover, the special design of the strengthening structure of the ear of the present application can effectively prevent the problem of cavities caused by uneven distribution of raw materials during the manufacturing process. And a wear-resistant support layer is provided, so that even if cavities appear, it will not wear and break during use, further improving the yield and service life of the floating body, which is beneficial to the construction of floating solar power and saves costs.

[0094] The above embodiments are only for illustrating the present invention and are not intended to limit the present invention. Those of ordinary skill in the relevant art can make various changes and modifications without departing from the scope of the present invention. Therefore, all equivalent technical solutions should also fall within the scope of the disclosure of the present invention.
