Floating flexible solar power generation bracket and solar power generation system

Abstract

A floating flexible solar power bracket and solar power system are provided. [Solution] The bracket (100) comprises a post assembly, a beam assembly, a cable assembly, and a first plumb bob assembly. The post assembly comprises at least two posts spaced apart, including a first post (110) floating on the water surface (302). The beam assembly comprises a cross beam corresponding to the top of the post, and the cable assembly comprises a load-bearing cable disposed on the cross beam and supporting a solar power generation module (200). The first plumb bob assembly comprises a first cable (161) and a first plumb bob, and is disposed on the first post to provide a downward force. One end of the first cable is fixed to the bottom of the water, and the other end is connected to the first plumb bob. When wind and waves arrive, the first post moves up and down with the waves. When the first post moves upward, the downward pulling force of the first plumb bob reduces the magnitude of the post's upward displacement to cope with the effects of wind and waves, stabilizing the entire system and reducing property damage caused by typhoons and other events.

Description

[Technical Field]

[0001] The present application relates to the technical field of flexible brackets, and in particular to floating flexible photovoltaic brackets and photovoltaic systems. [Background technology]

[0002] Flexible solar photovoltaic mounting brackets feature large spans and high clearances, allowing for spans of 10 to 30 meters. Simply installing foundations in appropriate locations and stringing prestressed steel or wire ropes can improve space utilization and increase installation capacity. Their structural characteristics allow flexible solar photovoltaic mounting brackets to be flexibly deployed in complex ocean, river, and lake environments, adapting to various terrains and water depths, thereby making full use of the spatial resources of oceans, rivers, and lakes. However, floating flexible mounting brackets are prone to drifting and are susceptible to strong winds and high waves, which can cause capsizing and tipping over, reducing stability and potentially causing serious property damage.

[0008] In some embodiments, the number of first pulley assemblies is eight, they are evenly spaced apart, and / or the number of first pulleys in each first pulley assembly is two.

[0009] In some embodiments, the cable assembly also includes wind-resistant cables passing through the at least two poles and positioned below the load-bearing cables, the number of the load-bearing cables being two, and a wind-resistant frame being provided between the two load-bearing cables and the wind-resistant cables.

[0010] Some embodiments further comprise a second mass assembly, the second mass assembly comprising a second cable and a second mass, one end of the second cable being anchored to the water bottom and the other end being connected to the second mass, the second mass assembly being disposed on the wind-resistant frame and providing a downward force.

[0011] Some embodiments further comprise a second pulley assembly, the second pulley assembly comprising a second pulley and a second pulley bracket, the second pulley being disposed within the second pulley bracket, the second cable being wound around the second pulley, the second pulley assembly being connected to the wind-resistant frame, and the second weight being attached to the wind-resistant frame.

[0012] In some embodiments, the wind-resistant frame includes a plurality of connecting rods, each connecting rod including a body and ears located at both ends of the body, the second pulley bracket including a base plate and two limiting plates located on either side of the base plate, the second pulley being located between the two limiting plates, and the base plate being fixedly connected to the ears of the connecting rods by fasteners.

[0013] In some embodiments, there are a plurality of second pulley assemblies, each of which is located at an end of the wind resistant frame where the load-bearing cable is connected.

[0014] In some embodiments, the at least two pillars further include a second pillar, and the first pillar and the second pillar each float on the water surface via a floating body, or the second pillar is fixed to the ground.

[0015] In some embodiments, the number of the second poles is two, the two second poles are fixed to the ground, the upper ends of the two second poles are inclined away from each other, and each of the two second poles has a side anchor cable on the side away from each other, one end of the side anchor cable is connected to the upper end of the second pole and the other end is connected to the ground, and the side anchor cable is arranged perpendicular to the ground.

[0016] In some embodiments, the first cable and the second cable are each fixed to the bottom of the water via a third weight, and / or the flotation mechanism is a floating body and the first pillar is fixedly connected to the floating body.

[0017] The present application also discloses a floating flexible solar power generation system comprising a solar power generation module and a floating flexible solar power generation bracket provided in any one of the above embodiments.

[0018] The present application has at least one of the following beneficial effects:

[0019] 1. In this application, a first weight assembly is attached to a first pillar and applies a downward force to the first pillar. At the same time, a first cable of the first weight assembly is fixed to the bottom of the water, restraining the first pillar within a predetermined range and preventing it from being washed away by wind or waves. When wind or waves approach, the first pillar moves up and down with the waves. When the first pillar tries to rise, the first weight exerts a downward gravitational force on the first pillar due to its own weight. Furthermore, the end of the first cable fixed to the bottom of the water also exerts a downward gravitational force on the first pillar, reducing the upward displacement of the first pillar, thereby counteracting the effects of wind and waves, stabilizing the entire system, and minimizing property damage caused by strong winds, etc.

[0020] 2. In the present application, the first sheave bracket that secures the first sheave includes two fixed plates spaced apart from each other, with the distance between these fixed plates being smaller than the width of the first weight. This allows the first weight to be positioned. During high waves and strong winds, when the pulling force of the first weight and the first cable cannot offset the upward force of the first pole, the first weight slides up to the first sheave bracket, and the fixed plates mechanically brake the first weight, thereby resisting the effects of strong winds and waves.

[0021] 3. In this application, the first pulley assembly is provided with two first pulleys, and the first cable is wound around the two first pulleys with multiple turns. As a result, when the first pole moves up and down due to the action of wind and waves, the first cable is restricted by friction with the first pulleys, reducing the sliding speed. The more turns the first cable has, the more significant the reduction in sliding speed becomes. The overall structure of the floating flexible solar power generation bracket is more stable and can better withstand the effects of large waves and wind during strong winds.

[0022] 4. In the present application, two load-bearing cables are provided, which can stably support the solar photovoltaic module while reducing the number of parts. At the same time, the provision of two load-bearing cables makes it easier to install the wind-resistant frame and improves the structural stability of the entire floating flexible photovoltaic bracket. In addition, in the present application, a second weight assembly is provided on the wind-resistant frame. When the floating flexible photovoltaic bracket is subjected to a headwind, the second weight of the second weight assembly provides a downward traction force to the floating flexible photovoltaic bracket through its own gravitational action. At the same time, the end of the second cable fixed to the water bottom also provides a downward traction force to the floating flexible photovoltaic bracket, improving the floating flexible photovoltaic bracket's ability to prevent tipping over.

[0027] Furthermore, the term "and / or," as used herein and in the appended claims, should be understood to refer to and include any and all possible combinations of one or more of the associated listed items.

[0028] It should be noted that unless otherwise specified or limited, the terms "attached," "coupled," and "connected" should be understood broadly. For example, they may refer to fixed, removable, or integral connections, mechanical or electrical connections, direct or indirect connections through an intermediary, and internal communication between two components.

[0029] In the embodiments shown in the accompanying drawings, directional indications (up, down, left, right, front, back, etc.) used to describe the structure and operation of each component of the present application are not absolute but relative. These descriptions apply when these components are in the positions shown in the accompanying drawings.

[0030] Furthermore, in this specification, terms such as "first," "second," etc. are used only to distinguish between descriptions and are not to be understood as indicating or implying relative importance.

[0031] According to a specific embodiment provided by the present application, as shown in FIGS. 1 to 4, a floating flexible solar photovoltaic bracket 100 is disclosed, which includes a post assembly, a beam assembly, and a cable assembly. The post assembly includes at least two posts arranged at a distance from each other. The beam assembly includes at least two cross beams 190 arranged corresponding to the tops of the posts. The cable assembly includes load-bearing cables 130 attached to the cross beams 190 on the at least two posts and used to support a solar photovoltaic module 200. The number of load-bearing cables 130 is preferably two to ensure stable support of the solar photovoltaic module 200.

[0032] The floating flexible solar photovoltaic power generation bracket 100 has the advantages of large span, high clearance, few consumables, strong wind resistance, adaptability to large tilt angles, easy installation, low pile foundation construction difficulty, low cost, etc. It does not require large-scale installation, can adapt to various terrains and water depth conditions, and is suitable for more investors.

[0033] 1 to 5, the at least two pillars include a first pillar 110 that floats on the water surface 302 via a floating mechanism. Specifically, a float 111 is installed on the water surface 302, and the float 111 floats on the water surface 302, with one end of the first pillar 110 fixed to the float 111. The floating flexible solar power generating bracket 100 also includes a first weight assembly, which includes a first cable 161 and a first weight 162. One end of the first cable 161 is fixed to the bottom of the water and holds the first pillar 110 in place within a predetermined range, thereby preventing it from being swept away by wind or waves. The other end of the first cable 161 is connected to the first weight 162. The first weight assembly is provided on the first pillar 110 and is used to provide a downward force to the first pillar 110. In addition to the floating body 111, the buoyancy mechanism may take other forms such as a buoyancy box, a group of floating blocks and a tow rope.

[0034] When subjected to the action of wind and waves, the first pillar 110 moves up and down following the waves. When the first pillar 110 tries to rise, the first weight 162 exerts a downward tractive force on the first pillar 110 by its own weight, suppressing the upward displacement of the first pillar 110. At this time, the end of the first cable 161 fixed to the bottom of the water also exerts a downward tractive force on the first pillar 110, and in cooperation with the first weight 162, offsets the tendency of the first pillar 110 to float upward, ensuring the stability of the entire system. This reduces physical damage to the floating flexible solar power generation bracket 100 caused by strong winds, etc.

[0035] 5 , the first cable 161 secures the first weight 162 to the first pillar 110 via the first pulley assembly 170. The first pulley assembly 170 includes a first pulley 171 and a first pulley bracket 172. The first pulley 171 is attached to the first pillar 110 via the first pulley bracket 172. The first pulley bracket 172 includes two spaced-apart fixing plates 1721 welded to the side walls of the first pillar 110. The first pulley 171 is rotatably attached between the two fixing plates 1721. The spacing between the two fixing plates 1721 is smaller than the width of the first weight 162, allowing the first weight 162 to be positioned quickly. In this way, when strong waves or strong winds occur, if the tension of the first weight 162 and the first cable 161 can no longer offset the force generated when the first pillar 110 floats up, the first weight 162 slides onto the first pulley bracket 172, and the fixed plate 1721 restricts the first weight 162 to form a mechanical brake, resisting the impact of strong winds and waves, effectively improving the floating flexible bracket's ability to withstand the impact of strong winds and waves, and improving the overall stability.

[0036] 4 and 5, preferably, eight first pulley assemblies 170 are provided, which allows the floating flexible solar power generating bracket 100 to better withstand the effects of wind and waves. The eight first pulley assemblies 170 are evenly spaced apart, which distributes the force acting on the first pole 110 evenly, reducing the possibility of capsizing due to unbalanced forces and improving stability.

[0037] In actual production, the number of first pulleys 171 in each first pulley assembly 170 may be one or more. In this embodiment, as shown in FIG. 5, the number of first pulleys 171 in each pulley assembly is preferably two. The first cable 161 is wound around two first pulleys 171, which results in multiple turns and allows for more reasonable force. When facing large waves, the multiple turns increase the friction between the first cable 161 and the first pulleys 171 and reduce the sliding speed of the first cable 161. The more turns there are, the more significant the weakening effect becomes, forming a mechanical brake.

[0038] Specifically, when the first pillar 110 moves up and down due to the action of wind or waves, the first cable 161 slides via the first pulley 171, and friction occurs between the first cable 161 and the first pulley 171, hindering the sliding of the first cable 161 and reducing the sliding speed of the first cable 161. Therefore, in this embodiment, two first pulleys 171 are provided to increase the number of turns of the first cable 161 and reduce the sliding speed of the first cable 161. The more turns of the first cable 161 increase, the more significant the reduction in the sliding speed of the first cable 161 becomes, and the overall structure of the floating flexible solar power generation bracket 100 becomes more stable and can better withstand the effects of large waves and wind during strong winds.

[0039] In an exemplary embodiment, the at least two pillars further include a second pillar 120, and the first pillar 110 and the second pillar 120 each float on the water surface 302 via a floating body 111. Preferably, there are two second pillars 120, one on each side of the first pillar 110. In this case, the second pillar 120 is also equipped with eight first pulley assemblies 170 and corresponding first cables 161 and first plumb bobs 162 to withstand the impact of large waves and wind forces.

[0040] Of course, in practical applications, one of the two second columns 120 may be floated on the water surface 302 via the floating body 111, and the other may be fixed to the ground 301. Alternatively, as shown in Figures 1 and 2, both second columns 120 may be fixed to the ground 301, and only the first column 110 may be floated on the water surface 302 via the floating body 111. This arrangement sacrifices the possibility of constructing the floating flexible solar power generation bracket 100 in the open ocean, but the overall structure is more stable. If it is constructed near the coast, such as in the sea or an estuary, it can significantly reduce asset damage caused by the floating flexible solar power generation bracket due to the effects of typhoons, etc.

[0041] Specifically, as shown in FIGS. 1 to 3 , the second pillars 120 are fixed to the ground 301, and the tops of the two second pillars 120 are inclined away from each other, so that the second pillars 120 are inclined relative to the ground 301. This provides better wind resistance than when the second pillars 120 are installed perpendicular to the ground 301. In addition, a side anchor cable 121 is provided on each of the two second pillars 120 on the sides that are spaced apart from each other. One end of the side anchor cable 121 is connected to the top of the second pillar 120, and the other end is connected to the ground 301. The side anchor cable 121 is disposed perpendicular to the ground 301, so that the second pillars 120 are stably fixed, further improving the stability of the entire structure of the floating flexible solar power generation bracket 100. The angle between the second pillars 120 and the load-bearing cable 130 is the same as the angle between the second pillars 120 and the side anchor cable 121. The second pillar 120 simultaneously receives a horizontal tension force F1 from the load-bearing cable 130 and a vertical downward tension force F2 from the lateral anchor cable 121. If the angle between the second pillar 120 and the load-bearing cable 130 is the same as the angle between the second pillar 120 and the lateral anchor cable 121, the direction of the resultant force F of tension forces F1 and F2 coincides with the axis of the second pillar 120. The second pillar 120 is an axially compressed member and is not affected by horizontal shear forces. This allows the second pillar 120 to be designed without horizontal shear forces. This shear-free design of this embodiment avoids the risk of damage to vertical pillars due to horizontal displacement of the foundation caused by excessive horizontal forces and reduces costs. In this embodiment, the inclination angle of the second pillar 120 with respect to the ground 301 is preferably 45°.

[0042] Specifically, as shown in Figure 3, a batter pile foundation 122 is installed on the ground 301. The second column 120 is fixed to the batter pile foundation 122 by anchor bolts or welding. The batter pile foundation 122 is arranged coaxially with the second column 120. Meanwhile, a side anchor support part 123 is installed on the ground 301. The side anchor cable 121 is tightened to the top of the second column 120 by pulling the anchor.

[0043] In a specific embodiment, as shown in Figures 2, 3, 5, and 6, a cross beam 190 is installed on the top of each of the second pillar 120 and the first pillar 110. This cross beam 190 is inclined with respect to the horizontal plane. In this case, by passing the load-bearing cable 130 through the cross beam 190, the photovoltaic power generation module 200 can be inclined with respect to the horizontal plane, thereby increasing the amount of power generation and improving power generation efficiency.

[0044] For example, the cable assembly may further include a wind-resistant cable 140 that passes through the first pillar 110 and the second pillar 120 and is located below the load-bearing cable 130. Specifically, one end of the load-bearing cable 130 and the wind-resistant cable 140 are each fixed to a cross beam 190 at the top of one of the second pillars 120, and the other end passes through the cross beam 190 at the top of the first pillar 110 and is fixed to a cross beam 190 at the top of the other second pillar 120. In this case, the number of load-bearing cables 130 is preferably two, and a wind-resistant frame 150 is provided between the two load-bearing cables 130 and the wind-resistant cables 140. One end of the wind-resistant frame 150 is fixedly connected to the two load-bearing cables 130, and the other end is fixedly connected to the lower wind-resistant cable 140. The load-bearing cable 130 and the wind-resistant cable 140 are connected by a wind-resistant frame 150, which improves the stability of the flexible photovoltaic bracket and improves the wind resistance of the floating flexible bracket.

[0045] The wind-resistant frame 150 may be a triangular, quadrangular, pentagonal, or other polygonal pyramid-shaped structure. In this embodiment, as shown in FIG. 6 , the wind-resistant frame 150 has a triangular pyramid structure. The overall structure of the triangular pyramid-shaped wind-resistant frame 150 is formed by connecting multiple connecting rods 151 end to end. Each connecting rod 151 includes a body and ears at both ends of the body. The ears are connected to the body by bending or welding. Fasteners secure the multiple connecting rods 151 by passing through the ears of adjacent connecting rods 151. In this embodiment, the fasteners are specifically eye bolts. The threaded rods of the eye bolts pass through the ears of the connecting rods, and the load-bearing cables 130 and wind-resistant cables 140 pass through the eyes of the corresponding eye bolts to connect to the wind-resistant frame 150.

[0046] In this embodiment, the use of two load-bearing cables 130 can stably support the photovoltaic module 200 while reducing the number of parts, making installation easier and more cost-effective. Furthermore, the use of two load-bearing cables 130 makes it easier to install the wind-resistant frame 150 and improves the structural stability of the entire floating flexible photovoltaic bracket 100.

[0047] 2 and 6, the floating flexible solar photovoltaic bracket 100 also includes a second weight assembly, which includes a second cable 163 and a second weight 164, one end of the second cable 163 being fixed to the water bottom and the other end being connected to the second weight 164. The second weight assembly is disposed on the wind-resistant frame 150 and provides a downward force.

[0048] 6 and 7 , in this embodiment, the second cable 163 installs the second weight 164 on the wind-resistant frame 150 via the second pulley assembly 180. Specifically, the wind-resistant frame 150 is provided with the second pulley assembly 180, which includes a second pulley 181 and a second pulley bracket 182. The second pulley 181 is disposed within the second pulley bracket 182. The second cable 163 is wound around the second pulley 181. The second pulley bracket 182 is fixed to the ear of the connecting rod 151 of the wind-resistant frame 150. Furthermore, the second pulley bracket 182 includes a base plate 1821 and limit plates 1822 located on both sides of the base plate 1821. Both ends of the rotation shaft are fixed to the two limit plates 1822, respectively, and pass through the center of the second pulley 181. The threaded rod of the eyebolt that secures the wind-resistant frame 150 passes through the ear of the corresponding connecting rod 151 and continues through the base plate 1821 , thereby securing the second pulley assembly 180 to the wind-resistant frame 150 .

[0049] In this embodiment, the second pulley assemblies 180, the second cables 163, and the second weights 164 are arranged in one-to-one correspondence, the number of the second pulley assemblies 180, the second cables 163, and the second weights 164 is three, and the three second pulley assemblies 180 are respectively arranged at the end positions where the wind-resistant frame 150 is connected to the load-bearing cables 130.

[0050] When the floating flexible solar power generation bracket 100 is affected by a headwind, the second weight 164, by its own gravitational force, provides a downward pulling force to the floating flexible solar power generation bracket 100. At the same time, one end of the second cable 163 fixed to the water bottom also provides a downward pulling force to the floating flexible solar power generation bracket 100, thereby improving the ability of the floating flexible solar power generation bracket 100 to prevent tipping over in strong winds.

[0051] In the above-described embodiment, the first cable 161 and the second cable 163 are respectively fixed to the bottom of the water via the third weight 165. The weight of the third weight 165 is preferably 2 tons or more, and sinks to the bottom of the water to achieve better fixing effect. At the same time, the third weight 165 provides a downward traction force to the floating flexible solar photovoltaic bracket 100 by its own gravitational action, and cooperates with the first weight 162 and the second weight 164 to counteract the influence of wind waves when wind waves arrive.

[0052] Specifically, when assembling the floating flexible solar photovoltaic bracket 100 on site, the piles are first driven into the quay. The battered pile foundations 122 are driven into the quay at the designed intervals to ensure they are horizontally aligned. The depth of the piles must be theoretically calculated and constructed in accordance with regulatory requirements. Next, depending on the site conditions, the second column 120 is installed and fixed to the battered pile foundations 122 using anchor bolts or welding. The installation angle of the second column 120 is carefully controlled so that the inclination angle of the cross beam 190 above it matches. Next, the first column 110 is installed. The ground height is measured at the water surface. After determining the span, the third weight 165 is submerged in water from eight different directions. Before submerging, the first cable 161 is fixed to the third weight 165. After confirming that the third weight 165 has sunk, the first cable 161 is wound around the first pulley 171 and fixed to the first weight 162 and the floating body 111. The weight of the first weight 162 must be calculated in advance. Next, the load-bearing cable 130 is installed. Using anchors, the load-bearing cable 130 is passed through the first pillar 110 and fastened to the cross beams 190 of the second pillars 120 on both sides. The preload force must be calculated in advance. Next, the wind-resistant frame 150 is installed. First, the wind-resistant frame 150 is assembled from below, and the installation position is measured. Once the position is determined, it is secured to the load-bearing cable 130 using a U-lock, clamp, or other method. Next, a steel wire rope is fastened from below to form the wind-resistant cable 140. Next, the first pulley 171 is secured to the wind-resistant frame 150 or the load-bearing cable 130. At the same time, the sinking position of the third weight 165 is measured (this is the same as when the third weight 165 sinks to the bottom). After confirmation, the third weight 165 is submerged, the second cable 163 is wound around the second pulley 181, and finally the second weight 164 is secured. At this time, the weight of the second weight 164 needs to be calculated in advance. Next, the side anchor cable 121 is installed, the side anchor support part 123 is fixed to the ground 301, and the side anchor cable 121 is fastened to the cross beam 190 of the second pillar 120 like an anchor. It should be noted that in this design, a batter pile foundation 122 is used to install the second pillar 120. Also, the side anchor cable 121 needs to be directed vertically downward so that it forms a vertical angle with the ground 301 when fastened.Finally, the photovoltaic module 200 is installed onto the load-bearing cable 130 using a pressure block, thereby completing the assembly of the floating flexible photovoltaic bracket 100.

[0053] The present application also provides a floating flexible solar power generation system suitable for offshore, lake, riverbed, and other situations, the system including a solar power generation module 200 and a floating flexible solar power generation bracket 100 provided by any of the above embodiments, wherein the solar power generation module 200 is disposed on the floating flexible solar power generation bracket 100.

[0054] Compared with traditional fixed brackets, the flexible solar photovoltaic bracket has a significantly larger span and clearance, which allows for more efficient use of the installation space of floating solar power plants and increases their installation capacity.To address the problem of flexible solar power systems being swept away by waves and potentially capsizing in strong waves, this application uses two side columns and eight cable weight structures fixed to the shore, which shortens the drift distance of the flexible solar power system when affected by wind and waves and minimizes property damage caused by strong winds.
