The following is a detailed description by way of specific examples.

Connector reinforcement

In the floating body array, adjacent floating bodies are connected to the through pieces of the connecting pieces, shearing force is exerted on the through pieces by the action of waves of the water surface between the adjacent floating bodies, and the shearing force acting on the through pieces is correspondingly increased along with the increase of the distance between the floating bodies. Thus, modifications to the through-penetration to increase shear resistance are described in detail below.

FIG. 6 is a schematic view of a penetration according to one embodiment of the present application. As shown, the penetrating member 600 comprises a stop 610 and a penetrating rod 620, wherein the penetrating rod 620 is connected to the stop 610 and extends outward from the stop 610 to pass through the holes of the first pull tab and the second pull tab to connect the first pull tab and the second pull tab, similar to the embodiment of fig. 4. In some embodiments, the joint between the stopper and the penetrating rod may not include threads, so that the strength of the joint between the stopper and the penetrating rod may be increased, and the strength of the penetrating member may be improved.

In some embodiments, the penetration 600 further includes a support 630, which may be disposed in the hollow chamber of the piercing rod 620, which may increase the shear resistance of the penetration. In some embodiments, the position of the supporting element disposed in the hollow chamber overlaps with the positions of the first pull tab and the second pull tab contacting with the penetrating rod, in other words, the height of the supporting element is at least greater than the distance between the two farthest sides of the first pull tab and the second pull tab. So that shearing forces to the through-penetration during floating of the first and second floats can be resisted. In some embodiments, the height of the support does not exceed the perforation of the rod, avoiding blocking the perforation, so that the locking element cannot be inserted into the perforation. In some embodiments, support 630 may be a rigid material. For example: metals or alloys, ceramics, carbon fibers, and the like.

In some embodiments, the rod 620 may further include a core (not shown), which may be disposed in the hollow chamber of the rod 620, and may be used to socket the support 630. For example, the core may be disposed at the center of the hollow chamber, and the support 630 may be directly sleeved on the core so as to be disposed in the hollow chamber. In some embodiments, the core may be tapered in shape to facilitate nesting of the support members. In some embodiments, the material of the core may be a polymeric elastomeric material.

In some embodiments, the penetrating rod 620 may include one or more through grooves (not shown) extending from a side away from the stopper to a side of the stopper and communicating with the hollow chamber. The side walls of the hollow chamber may be slightly flared outwardly from the hollow chamber to facilitate the placement of the support member within the hollow chamber. In some embodiments, the groove is disposed on at least a portion of the rod. For example: the side wall of the hollow chamber far away from the end of the stop head can be outwards expanded through the end far away from the stop head, so that the support piece can conveniently enter the hollow chamber. By means of the end piece having a diameter smaller than the diameter of the through-rod, the side wall of the hollow chamber, including the groove portion, can be limited to be retracted into the hollow chamber, so that the support can be enclosed in the hollow chamber.

The penetration may also include other reinforcement means as will be appreciated by those skilled in the art. Other solutions for increasing the shear resistance of a penetration are also provided.

In some embodiments, the penetration 800 further includes a support layer 830, which may be disposed on an outer sidewall of the piercing stem 820, which may increase the shear resistance of the penetration. In some embodiments, the position of the supporting layer disposed on the outer sidewall overlaps with the position of the first pull tab and the second pull tab contacting with the penetrating rod, in other words, the height of the supporting layer is not less than the distance between the two sides of the first pull tab and the second pull tab farthest away from each other. So that shearing forces to the through-penetration during floating of the first and second floats can be resisted. In some embodiments, the height of the support layer does not exceed the perforations of the through-rods, avoiding blocking the perforations, so that the locking elements cannot be inserted into the perforations. In some embodiments, the support layer 830 may be a rigid material. For example: metals or alloys, ceramics, carbon fibers, and the like.

In some embodiments, the depth of the groove may be the same as or slightly greater than the thickness of the support layer. In some embodiments, the support layer may be expanded by heating, and then sleeved into the groove of the rod, and then shrunk by cooling, and the support layer is tightly clamped in the groove of the rod, thereby completing the assembly of the support layer. In some embodiments, the penetration may be factory pre-installed with the support layer.

In some embodiments, the penetration assembly 800 further comprises a buffer layer 840, which may be disposed outside the support layer and wraps the support layer, may buffer the force generated by the first pull tab and/or the second pull tab during movement, and may also protect the support layer (e.g., rust prevention, corrosion prevention, etc.).

In some embodiments, the position of the support coincides with the contact position of the adjacent floating body with the connection member, so that the shearing force of the floating of the adjacent floating body can be resisted. In some embodiments, the hollow chamber may include a core of a polymer elastomer material therein, and the support may be sleeved on the core and disposed in the hollow chamber. In some embodiments, the support may be enclosed in the hollow chamber with a closure. In some embodiments, the through-member includes an outwardly-extending sidewall that forms a hollow chamber, in other words, the through-member includes one or more grooves in the sidewall that allow the sidewall of the through-member to be slightly outwardly-expanded to facilitate the placement of the support member in the hollow chamber. In some embodiments, a stop member sized slightly smaller than the penetration member may be provided on the penetration member so that the side walls of the outer strut may be restrained, contracting inwardly, to define the support member. In some embodiments, the support may be pre-disposed in the hollow chamber. For example: before the penetration piece leaves the factory. In some embodiments, the material of the support is a rigid material. For example: metals or alloys, ceramics, carbon fibers, and the like.

Floating body pull lug reinforcement

In the floating body array, the connection between the adjacent floating bodies needs to be connected through the pull lugs of the adjacent floating bodies. In areas with complex environments, the wind waves are often accompanied, the adjacent floating bodies can fluctuate, and in the fluctuation process, the adjacent pull lugs can generate interaction force, so that the pull lugs of the floating bodies are easily broken. Therefore, the improved scheme of the floating body pulling lug is described in detail below to increase the strength of the pulling lug.

Fig. 10A and 10B are schematic views of a float according to one embodiment of the present application. As shown, the float 1000 includes a body 1010 and one or more pull ears 1020. Wherein one or more pull tabs 1020 extend outwardly from the body 1010 and may be used for connection between adjacent buoyant bodies. In some embodiments, the pull tab 1020 can extend outward from a corner or a location near a corner of the body 1010. In some embodiments, 8 pull tabs are provided on each side of the float 1000 that is connected to the other floats. Every 2 pull lugs are used for connecting with one other floating body. Specifically, each of the 2 pulling lugs includes a first pulling lug 1021 provided at a corner of the floating body 1000 and extending outward from the main body, and a second pulling lug 1022 provided on a side of the floating body 1000, the second pulling lug 1022 being adjacent to the first pulling lug 1021 but spaced apart from the first pulling lug 1021. In some embodiments, the floating body 1000 may not include the second pull tab, and the floating body 1000 is connected to other floating bodies only through the first pull tab. In some embodiments, the pull tab 1020 and the main body 1010 can be integrally formed. In some embodiments, the float 1000 is blow molded.

In some embodiments, the float 1000 may also include one or more mounts 1030 that may be used in conjunction with a rack so that a solar panel secured to the rack may be supported. In some embodiments, the seat 1030 may be located on a pull tab at a corner of the body. In some embodiments, the support 1030 may also be located in other positions. For example: on the body 1010. In some embodiments, the material of the float 1000 may be a high density polyethylene material, which has high strength, toughness and durability.

In some embodiments, the main body 1010 is similar to a main body of a conventional floating body, and the technical solution of the present application mainly increases the strength of the pull tab, so the main body structure is not described herein again.

Further, referring to fig. 10B, the pull tab 1020 is integrally formed with the main body, and naturally extends outwardly therefrom. The pull tab comprises a tab 1023 and a through hole 1024 formed in the tab so that a connector such as a bolt can pass through the through hole. In order to increase the strength of the pulling lug, a reinforcing structure can be arranged on the lug plate.

In some embodiments, the reinforcing structure may include a first reinforcing rim 1001 and a second reinforcing rim 1002. The first reinforcing edges 1001 are arranged on two sides of the ear plate and arranged around the through hole 1024, and the second reinforcing edges 1002 are arranged on two sides of the ear plate and arranged around the edge of the ear edge, 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 reinforcing structure may further include a reinforcing ring 1003 disposed on each side of the ear plate between the first and second reinforcing edges 1001 and 1002 and dividing the ear plate into a first region and a second region, wherein the first region is a region between the first reinforcing edge and the reinforcing ring, and the second region is a region between the second reinforcing edge and the reinforcing ring. In some embodiments, the stiffener ring 1003 has the same shape as the first stiffener and/or the through hole. In some embodiments, the first reinforcing edge and the second reinforcing edge are the same distance from the reinforcing ring at the pull tab arc portion.

In some embodiments, the reinforcing structure may further include a plurality of reinforcing bars 1004 disposed in the first and second regions, which may increase the strength of the ear plate. In some embodiments, the reinforcing strips are disposed divergently in the first and second regions. Wherein the reinforcing strips in the first region connect the reinforcing rings and the first reinforcing edge, and the reinforcing strips in the second region connect the reinforcing rings and the second reinforcing edge. In some embodiments, the locations of the reinforcing strips in the first region and the reinforcing strips in the second region on the reinforcing ring do not overlap, in other words, the reinforcing strips in the first region and the reinforcing strips in the second region are not connected on the reinforcing ring. Therefore, the phenomenon that when the lug plate is manufactured by blow molding, the raw materials are concentrated to cause uneven distribution and the lug is pulled to form a cavity can be prevented. As understood by those skilled in the art, when the floating body floats along the water surface in use, the adjacent lug plates are in a friction state for a long time, and if the lug pulling cavities are easy to damage and break, the floating body leaks air, and the use of the floating body is influenced.

In some embodiments, the first region stiffener and/or the second region stiffener are equally spaced on the stiffener ring. That is, the reinforcing bars are disposed at equal intervals on the reinforcing ring. In some embodiments, the first region stiffener and the second region stiffener are connected to the stiffener ring in an alternating manner. In some embodiments, the first region reinforcing strip and/or the second region reinforcing strip may have other arrangements. For example: crossing the existing reinforcing bars, etc.

In some embodiments, the pull tab 1020 may further include a wear-resistant support layer (not shown) disposed on both sides of the ear plate and completely covering the reinforcing structure of the ear plate, so as to coat the pull tab, thereby preventing the pull tab from being damaged and broken in use after the pull tab has a cavity, and protecting the pull tab. In some embodiments, the wear-resistant support layer may be a rigid material, which may further increase the strength of the tab. In some embodiments, the rigid material may be a metal or alloy, ceramic, carbon fiber, or the like.

In some embodiments, the pulling lug 1020 can further include a support core (not shown) disposed in the lug plate and can be coupled to the body 1010 to increase the strength of the pulling lug. In some embodiments, the support core may be shaped to conform to the shape of the ear plate and/or the through-hole to facilitate uniform loading of the support core during use of the pull ear. In some embodiments, the support core may be a rigid material. For example: metals or alloys, ceramics, carbon fibers, and the like.

Fig. 11 is a flow chart of a method of manufacturing a floating body according to one embodiment of the present application. In step 1110, a first channel is provided in a tab portion of a float body mold around a tab connection hole. In some embodiments, a first reinforcing rim protruding from the tab plate may be formed when the material from which the float is formed enters the first passage of the tab portion of the float mold.

In step 1120, a second channel is provided in the tab portion of the float body mold around the tab edge. In some embodiments, a second reinforcing rim protruding from the tab portion of the float can be formed as the material from which the float is formed enters the second passage of the tab portion of the float die.

In step 1130, a ring-shaped channel is provided in the tab portion of the float mold and positioned between the first channel and the second channel, dividing the ear plate portion into a first region and a second region. In some embodiments, the reinforcing ring protruding from the tab portion of the float can be formed as the material from which the float is formed enters the annular channel of the tab portion of the float die.

In step 1140, radial strips are provided in the first and second regions of the floating body mold tab portions. In some embodiments, the reinforcing strips protruding from the tab portions of the float mold may be formed as the material from which the float is made enters the radial strips of the tab portions of the float mold. In some embodiments, the radial strips in the first region are not connected to the radial strips in the second region at the annular channel, so that the reinforcing strips on the tab ear plate are not connected to the reinforcing ring.

In some embodiments, in the floating body mold pull lug portions, a support core is disposed between the floating body molds. In some embodiments, the support core may be wrapped as the material from which the float is made enters the pull tab portion of the float mold, so that the support core may be placed in the pull tab of the float. In some embodiments, the support core is shaped similarly to the float tab shape, also with through holes to facilitate connection of adjacent floats. In some embodiments, the support core may extend over the body portion of the float mold so that the stock of the body portion may also wrap around a portion of the support core, which may be attached to the body portion of the float. In some embodiments, the distance between the support core and the floating body molds on two sides is the same, so that the support core can be arranged in the middle of the pull lug to ensure the strength of the pull lug. In some embodiments, the material of the support core is different from the material of the float.

In some embodiments, a wear support layer is provided on the float die in the pull tab portion of the float die. In some embodiments, when the raw material for manufacturing the floating body enters the pulling lug part of the floating body die, the wear-resistant supporting layer can be thermally set with the heated raw material, so that the wear-resistant supporting layer can be arranged on the surface of the pulling lug of the floating body. In some embodiments, the shape of the wear-resistant supporting layer can be completely the same as that of the pull lug part of the floating body die, so that the wear-resistant supporting layer can be completely attached to the pull lug part of the floating body die and can also be completely attached to the pull lug of the floating body die. In some embodiments, the wear-resistant support layer may be pre-affixed in the float mold. In some embodiments, the wear-resistant support layer is a different material than the float.
