Description

Technical Field

[0001] The invention relates to a wind-resistant mechanism and a water surface flexible photovoltaic bracket, belonging to the technical field of water surface photovoltaics. Background Art

[0002] The country has vigorously promoted photovoltaic power generation technology. In order to improve the efficiency of land use, photovoltaic projects such as fishery-photovoltaic complementarity, agricultural-photovoltaic complementarity, and mountain photovoltaics have emerged in recent years. my country is rich in water resources and has many lakes and reservoirs. The development of water-based photovoltaic power stations can remove the constraints of land factors and broaden the application of photovoltaic power generation.

[0003] Flexible photovoltaic brackets have the characteristics of high clearance and large span, and are widely used in water surface photovoltaic power stations. However, since flexible photovoltaic brackets install photovoltaic modules through cable structures, they are more susceptible to strong winds than fixed brackets, and higher safety requirements are put forward.

[0004] Under the action of upwind wind load, the vertical component of wind load will cause the structure to displace upward. At this time, the upwind wind load is mainly borne by the bottom load-bearing cables and other load-bearing structures, and the overall requirements for the bottom stability structure are relatively high. Under this working condition, there are mainly two problems: 1. Under the action of upwind wind load, the stabilizing cable becomes loose, and the wind load is mainly borne by the load-bearing cables. The upward displacement is difficult to control. At present, most of the displacement requirements are met by increasing the initial cable force of the load-bearing cable. Because the entire structure needs to withstand a larger cable force, the cost increases. In addition, the upwind wind load can be resisted by designing a wind-resistant anchor structure. For most flexible photovoltaic brackets across the water surface, the construction cost is relatively high; 2. The axial force of the stabilizing cable changes greatly from the tensioned to the relaxed state, resulting in excessive stress amplitude, causing fatigue damage to the stabilizing cable.

[0005] In order to solve the above problems, this application proposes a wind-resistant mechanism and a flexible photovoltaic bracket on the water surface. Summary of the invention

[0006] The technical problem to be solved by the present invention overcomes the existing defects and provides a wind-resistant mechanism and a flexible photovoltaic bracket on the water surface. Gravity and water buoyancy will provide additional resistance in the opposite direction of the wind load displacement to reduce the amplitude. At the same time, the water resistance will dissipate energy and increase the structural damping ratio. Therefore, for the flexible photovoltaic bracket on the water surface in the water environment, the water environment can be cleverly utilized to solve the problem that the wind-resistant ground anchor solution in the prior art fixes the ground piles to the bottom of the water, which has the problems of high construction cost of the ground piles, insufficient stability of the ground piles, and excessive corrosion of the steel strands. The problems in the background technology can be effectively solved.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: A wind-resistant mechanism and a flexible photovoltaic support on a water surface, characterized in that the flexible photovoltaic support is applied to a flexible photovoltaic support on a water surface, the flexible photovoltaic support comprises a plurality of load-bearing cable groups, each load-bearing cable group comprises at least two load-bearing cables arranged in parallel at intervals and used to support photovoltaic modules, and the wind-resistant structure comprises: Wind-resistant cables, tensioned and arranged below the load-bearing cable group; A connecting component, fixedly connected to the bottom of the wind-resistant cable and / or the load-bearing cable; The floating member is arranged at the bottom of the connecting member, the floating member is partially immersed in the water, and a water inlet hole for water to enter and exit is opened at the bottom of the floating member.

[0008] As a further improvement of the present invention, the floating member is configured as a hollow structure, and an opening for air inlet and outlet is provided on the top of the floating member. In a natural state, the floating member at least partially extends out of the water.

[0009] As a further improvement of the present invention, the connection assembly includes a first clamping plate, which is clamped on the wind-resistant cable, and a first connecting rod is arranged at the bottom of the first clamping plate, and the bottom of the first connecting rod is connected to the floating member.

[0010] As a further improvement of the present invention, a second clamping plate is clamped on the load-bearing cable, and the bottom of the second clamping plate is connected to the first clamping plate through a second connecting rod.

[0011] As a further improvement of the present invention, a reinforcing rod is arranged on the second clamping plate or the second connecting rod, and the reinforcing rod is arranged in an X shape.

[0012] As a further improvement of the present invention, triangular components are fixedly connected between adjacent load-bearing cables and wind-resistant cables, and the first clamping plate is fixedly connected to the triangular component via a rigid rod.

[0013] As a further improvement of the present invention, the floating member is configured as a pontoon or an elliptical float, a rectangular through hole is opened on the top of the floating member, a connecting plate is fixedly connected to the bottom of the first connecting rod, and the connecting plate and the pontoon are fixedly connected by T-bolts.

[0014] As a further improvement of the present invention, the buoy is composed of a top cylinder, an intermediate cylinder, and a bottom cylinder, and the intermediate cylinder is respectively connected to the top cylinder and the bottom cylinder by threaded connection.

[0015] As a further improvement of the present invention, the buoy is configured as a conical structure with a bottom area larger than a top area.

[0016] To achieve the above-mentioned purpose, the present invention provides a flexible photovoltaic support on the water surface, including the above-mentioned wind-resistant mechanism, and also including end columns and middle columns. After the load-bearing cable group is prestressed, it is tensioned between the end columns and passes through the middle columns, and the wind-resistant cable is tensioned between the end columns and the middle columns.

[0017] The beneficial effects of the present invention include: a wind-resistant mechanism and a flexible photovoltaic bracket on the water surface, wherein a wind-resistant mechanism consisting of a wind-resistant cable, a connecting component, and a floating component is added to the existing flexible photovoltaic bracket. When the floating component is driven up and down by the wind force on the overall flexible photovoltaic bracket, the instantaneous change in the length of the floating component submerged in the water is much larger than the change in the water level inside the floating component, thereby providing reverse resistance for the movement of the photovoltaic flexible bracket, reducing the maximum amplitude of the photovoltaic flexible bracket, and improving the wind-resistant performance of the flexible photovoltaic bracket on the water surface, especially for upward wind loads. In combination with the characteristics of flexible photovoltaics on the water surface, the buoyancy, gravity, and viscosity of water are used to improve the wind-resistant effect in the upwind direction, thereby improving the stability of the overall structure.

[0030] Example For large-span photovoltaic system application scenarios, flexible brackets are usually used as structural support systems. Flexible brackets generally form initial stiffness by providing pre-tension to the cables, thereby resisting the self-weight of the photovoltaic system and external loads. Currently, photovoltaic flexible brackets on the market can be roughly divided into single-layer cable and double-layer cable structures. The double-layer cable structure can be divided into upper load-bearing cables and lower stabilizing cables according to the force properties of the cables. From the perspective of spatial layout, the load-bearing cables are arranged horizontally, mainly to bear the loads from the self-weight of the photovoltaic components on the upper part of the structure, wind loads, snow loads, etc.; the stabilizing cables are placed below the load-bearing cables to support the upper load-bearing cables, provide vertical support for the load-bearing cables, and make the overall wind-resistant and stable.

[0031] Flexible photovoltaic brackets have the characteristics of high clearance and large span, and are widely used in water surface photovoltaic power stations, such as common fish-photovoltaic complementary, sewage treatment plants and other scenarios.

[0032] However, under the action of upwind wind load (i.e. upward wind load), the vertical component of wind load will cause the structure to displace upward. At this time, the upwind wind load is mainly borne by the bottom load-bearing cables and other load-bearing structures, which places high demands on the overall stability of the bottom structure. As the upward displacement increases, the axial force of the stabilizing cable will become smaller and smaller, or even zero. Under this working condition, there are two main problems: 1. Under the action of upwind wind load, the stabilizing cable becomes loose, and the wind load is mainly borne by the load-bearing cable, and the upward displacement is difficult to control. In the prior art, some manufacturers meet the displacement requirements by increasing the initial cable force of the load-bearing cable. Since the entire structure needs to withstand a larger cable force, this solution will undoubtedly lead to an increase in cost. In addition, for flexible photovoltaic brackets on land, some manufacturers in the prior art use wind-resistant ground anchor solutions for reinforcement to resist upwind wind loads, such as Chinese patents with publication numbers CN115276521A and CN221614867U. However, when the above solution is applied to flexible photovoltaic brackets on the water surface, since the ground piles need to be fixed to the bottom of the water, there are problems such as high construction cost of the ground piles, insufficient stability of the ground piles, and excessive corrosion of the steel strands. This solution is obviously not suitable for use on flexible photovoltaic brackets on the water surface; 2. The axial force of the stabilizing cable changes greatly from the tensioned state to the relaxed state, thereby generating an excessively large stress amplitude, causing fatigue damage to the stabilizing cable.

[0033] In order to solve the problems existing in the prior art, improve the anti-wind performance of the flexible photovoltaic bracket on the water surface, and avoid fatigue damage caused by stress relaxation of the stabilizing cable, the present invention provides a wind-resistant mechanism and a flexible photovoltaic bracket on the water surface, which, combined with the characteristics of flexible photovoltaics on the water surface, utilize the buoyancy and viscosity of water to improve the wind-resistant effect in the against-wind direction.

[0034] like Figure 1-Figure 7As shown, a wind-resistant mechanism disclosed in the present invention is applied to a flexible photovoltaic support on a water surface. The flexible photovoltaic support includes a plurality of load-bearing cable groups, each of which includes at least two load-bearing cables 3 arranged in parallel and spaced apart for supporting photovoltaic modules. The wind-resistant structure includes: The wind-resistant cable 4 is tensioned and arranged below the load-bearing cable group 3. In a windless state, the wind-resistant cable 4 is only subjected to the force of gravity; A connecting component, fixedly connected to the bottom of the wind-resistant cable 4 and / or the load-bearing cable 3; The floating member is arranged at the bottom of the connecting member, the floating member is partially immersed in the water, and a water inlet hole for water to enter and exit is opened at the bottom of the floating member.

[0035] Specifically, the load-bearing cables 3 and the wind-resistant cables 4 are both configured as steel strands.

[0036] In some optional embodiments, the float is configured as a hollow structure, and an opening for air inlet and outlet is provided on the top of the float. In a natural state, the float at least partially extends out of the water. The natural state refers to a state in which the float is placed in water after being installed through a connecting assembly.

[0037] Furthermore, the connection assembly includes a first clamping plate 7, which is clamped on the wind-resistant cable 4. A first connecting rod 8 is arranged at the bottom of the first clamping plate 7, and the bottom of the first connecting rod 8 is connected to a floating member.

[0038] In some optional embodiments, a second clamping plate 19 is clamped on the load-bearing cable 3 , and the bottom of the second clamping plate 19 is connected to the first clamping plate 7 via a second connecting rod 6 .

[0039] Optionally, the first clamping plate 7 clamps the wind-resistant cable at the top of the first clamping plate 7 by a U-bolt, a U-clamp or a wire rope clamp, the second clamping plate 19 clamps the wind-resistant cable 4 at the top of the second clamping plate 19 by a U-bolt, a U-clamp or a wire rope clamp, and the bottom of the second connecting rod 6 is welded or connected to the first clamping plate 7 by bolts.

[0040] In some optional embodiments, a triangular component 11 is fixedly connected between adjacent load-bearing cables 3 and wind-resistant cables 4, and the first clamping plate 7 is fixedly connected to the triangular component 11 through a rigid rod. The function of the triangular component 11 is to connect multiple rows of flexible photovoltaic brackets into an integral structure, and to form a whole with the load-bearing cables 3 and wind-resistant cables 4 in a single row of flexible photovoltaic brackets. The specific structural form can be set to various structures in the prior art, which will not be repeated here. The first clamping plate 7 is connected to multiple triangular components 11 through a rigid rod as a whole, so that the function of the wind-resistant component can be transmitted to the overall flexible photovoltaic bracket.

[0041] In some optional embodiments, the floating member is configured as a pontoon 9 or an elliptical float or a lightweight hollow floating member in the form of other long strip structures. A rectangular through hole 14 is opened on the top of the floating member, and a connecting plate 12 is fixedly connected to the bottom of the first connecting rod 8. The connecting plate 12 and the floating member are fixedly connected by T-bolts 13. In order to save costs, after the T-bolts 13 are installed on the rectangular through hole 14, the rectangular through hole 14 is not completely sealed, and can also be used as an opening set on the top of the floating member for air entry and exit.

[0042] In practical applications, the total length of the float should be greater than the water level change height of the actual project site.

[0043] Optionally, the water inlet hole at the bottom of the float 9 is set as a circular through hole 10, and the circular through hole 10 is set on the side position of the bottom of the float 9 or on the bottom plate of the float 9. In addition, those skilled in the art should know that when the float 9 enters the water through the connecting piece, the water slowly enters the inside of the float 9 from the circular through hole 10 until it reaches balance, and when the water level changes, the liquid level inside the float 9 is also automatically balanced, thereby avoiding the failure of the float 9 due to the water level change.

[0044] The second connecting rod 6, the reinforcing rod 5, the first clamping plate 7 and the first connecting rod 8 form a rigid connection structure, thereby reducing the influence of the buoy 9 shaking left and right in the water.

[0045] Optionally, the buoy 9 is composed of a top cylinder 15, an intermediate cylinder 16, and a bottom cylinder 18. The intermediate cylinder 16 is respectively connected to the top cylinder 15 and the bottom cylinder 18 by threaded connection, and a multi-stage threaded connection structure is adopted, which is convenient for adjusting the height of the buoy 9 according to the actual situation of the project site and has wider adaptability.

[0046] In addition, the float 9 can also be set to a conical structure with a bottom area larger than a top area. When the float 9 is set to a conical structure, it can provide greater resistance when the photovoltaic flexible support moves up and down.

[0047] In addition, the present application also discloses a flexible photovoltaic support on the water surface, including the above-mentioned wind-resistant mechanism, and also including end columns 2 and middle columns 1. After the load-bearing cable group is prestressed, it is tensioned between the end columns 2 and passes through the middle columns 1, and the wind-resistant cable 4 is tensioned between the end columns 2 and the middle columns 1.

[0048] It should be noted that the tensioning here can be understood as the pre-tensioning stage. For example, the steel strand will have sag under its own weight. Tensioning refers to straightening the steel strand without sag, but there is no additional prestress applied to the steel strand. Post-tensioning after prestressing refers to adding tension in the load-bearing cable 3 in advance, so that the prestressed tensioned member is subjected to compressive stress, thereby causing it to produce a certain deformation to cope with the loads on the structure itself, including the load of the member's own weight, wind load, snow load, earthquake load, etc. Prestress is applied by the steel strand to put the member in a compressive state, so that it can resist a certain deformation under the action of external force, thereby improving the stiffness and stability of the structure.

[0049] As one of the implementation examples of the present invention The wind-resistant mechanism includes a plurality of load-bearing cable groups, each of which includes at least two load-bearing cables 3 arranged in parallel and spaced apart for supporting photovoltaic modules. The wind-resistant structure includes: A wind-resistant cable 4, tensioned and arranged below the load-bearing cable group; A connecting component, fixedly connected to the bottom of the wind-resistant cable or the load-bearing cable; The floating member is arranged at the bottom of the connecting member, the floating member is partially immersed in the water, and a water inlet hole for water to enter and exit is opened at the bottom of the floating member.

[0050] Specifically, the connecting assembly includes a first clamping plate 7 and a first connecting rod 8, wherein the first clamping plate 7 is connected to the wind-resistant cable by a U-bolt, a U-shaped clip or a wire rope clamp, the bottom of the first clamping plate 7 is connected to the first connecting rod 8, and the bottom of the first connecting rod 8 is connected to the floating member.

[0051] More specifically, the floating member is configured as a pontoon 9 with a hollow structure and an elongated strip, and an opening for air inlet and outlet is provided on the top thereof. During installation, the pontoon 9 is partially submerged in water, and the top is fixedly connected to the load-bearing cable 3 through a connecting member consisting of a first clamping plate 7 and a first connecting rod 9.

[0052] When the wind load is not loaded, the water surfaces inside and outside the buoy 9 are level, and the buoyancy of the buoy 9 is approximately equal to its own gravity, which will not increase the load of the overall photovoltaic flexible bracket. When the overall water surface photovoltaic bracket is subjected to the upwind wind load, the load-bearing cable 3 drives the buoy 9 to move upward. At this time, the water has not completely leaked out of the water inlet hole, resulting in the water level in the buoy 9 being higher than the water surface. In this way, the gravity of the buoy 9 is greater than the buoyancy. At the same time, when the bottom of the buoy 9 leaves the water surface, it will be subject to the viscous resistance of the water. The buoy 9 provides a downward resistance, and the wind load amplitude will be reduced. Similarly, when the overall water surface photovoltaic bracket is subjected to the downward wind load, the photovoltaic components and load-bearing cables installed on the top of the bracket are displaced downward, pressing the buoy 9 downward. At this time, the water surface in the buoy 9 is lower than the outside, resulting in the buoyancy being greater than the gravity, providing an upward resistance. At the same time, when the buoy 9 moves in the water, the water can provide a certain resistance, which is equivalent to increasing the vertical motion damping ratio of the structure, thereby playing a role in energy dissipation and amplitude weakening.

[0053] Therefore, gravity and water buoyancy will provide additional resistance in the opposite direction of wind load displacement to reduce the amplitude. At the same time, water resistance will dissipate energy and increase the structural damping ratio. Therefore, for the water surface photovoltaic flexible bracket in the water environment, the water environment can be cleverly utilized to solve the problems of high construction cost of piles, insufficient stability of piles, and rapid corrosion of steel strands in the existing wind-resistant ground anchor solution to fix the piles on the bottom of the water.

[0054] In addition, the present application also discloses a flexible photovoltaic support on the water surface, as one of the examples, including a load-bearing cable 3 that is tensioned between the end columns 2 and passes through the middle column 1 after applying prestress, and an anti-wind cable 4 that is tensioned between the end columns 2 and the middle column 1, the anti-wind cable 4 is fixedly connected to a connecting member 7, and a buoy 9 for wind resistance is fixedly connected to the bottom of the connecting member 7 through a first connecting rod 8, the bottom of the buoy 9 is partially submerged in water, and the top and bottom of the buoy 9 are provided with openings, wherein the opening at the top is used for the entry and exit of air, and the water inlet at the bottom is used for the entry and exit of water. Preferably, the size of the opening is much smaller than the bottom area or top area of ​​the buoy 9, and the length of the buoy 9 can be determined according to the actual water level change at the project site, that is, the length of the buoy 9 is greater than the water level change to ensure that the buoy 9 is at least partially submerged in water.

[0055] Similarly, when the connecting assembly is fixedly connected to the bottom of the wind-resistant cable 4, the floating member can also play a wind-resistant role.

[0056] As the second implementation example of the present invention The wind-resistant mechanism includes a plurality of load-bearing cable groups, each of which includes at least two load-bearing cables 3 arranged in parallel and spaced apart for supporting photovoltaic modules. The wind-resistant structure includes: A wind-resistant cable 4, tensioned and arranged below the load-bearing cable group; A connecting component, fixedly connected to the bottom of the wind-resistant cable and the load-bearing cable; The floating member is arranged at the bottom of the connecting member, the floating member is partially immersed in the water, and a water inlet hole for water to enter and exit is opened at the bottom of the floating member.

[0057] A triangular component 11 is fixedly connected between adjacent load-bearing cables 3 and wind-resistant cables 4, and the first clamping plate 7 is fixedly connected to the triangular component 11 via a rigid rod.

[0058] More specifically, the connecting assembly includes a first clamping plate 7, which is clamped on the wind-resistant cable 4. A first connecting rod 8 is provided at the bottom of the first clamping plate 7. The bottom of the first connecting rod 8 is connected to a floating member. A second clamping plate 19 is clamped on the load-bearing cable 3. The bottom of the second clamping plate 19 is connected to the first clamping plate 7 through a second connecting rod 6.

[0059] Multiple rows of brackets are combined and connected through the triangular component 11, the load-bearing cables 3 and wind-resistant cables 4 in the single-row brackets are connected through the first connecting rod 8, the first clamping plate 7, the second clamping plate 19, and the second connecting rod 6. The triangular component 11 and the connecting parts are combined through a rigid rod, so that the overall water surface flexible photovoltaic bracket can be formed into an integral structure, thereby having better wind resistance.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
