Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of flexible photovoltaic technology, and further relates to an anchoring assembly and a flexible photovoltaic support. BACKGROUND

[0002] The flexible photovoltaic support has been increasingly widely applied in the construction of photovoltaic power stations due to its advantages such as strong adaptability, full utilization of complex terrain, cost-effectiveness and the like. At present, the clamping anchor is generally used as the main form of the anchoring assembly in the industry. The traditional clamping anchor can basically meet the connection requirements between the steel strand and the base under normal working conditions, and a certain degree of fixing effect is achieved by means of the friction force between the clamping piece and the steel strand.

[0003] However, when the flexible photovoltaic support faces a harsh natural environment, problems will follow. In particular, in areas with large wind loads, the vibration caused by strong winds is frequent and severe. At this time, the external force on the steel cable of the flexible support will increase dramatically, far exceeding the stress level under calm weather. Since the traditional clamping anchor mainly relies on a relatively single friction clamping mechanism, under the impact of such high dynamic load, the steel strand has a high risk of slipping. Once the steel strand slips out of the anchoring assembly, the entire flexible support will lose the key stress support, and a collapse accident is likely to occur. This not only causes the photovoltaic power station to suffer serious damage to the power generation equipment, resulting in huge economic losses, but also can cause a series of safety hazards, endangering the safety of surrounding personnel and facilities.

[0016] And / or, the second fixing member is provided with a second limiting portion on the side away from the first fixing member, the second limiting portion is used to prevent the clamping structure from being pulled out of the second fixing member.

[0017] In some embodiments, the inner cavity of the first or second fixing member is a tapered cavity; the large-diameter end of the tapered cavity is close to the sleeve, the small-diameter end of the tapered cavity is away from the sleeve, and the outer contour of the clamping structure is arranged to be a tapered surface matched with the tapered cavity, and when the clamping structure is subjected to the tension of the steel strand, the clamping structure can slide along the tapered cavity to the small-diameter end, so as to gradually compress the outer periphery of the steel strand to fix the position of the steel strand.

[0045] In addition, in the description of the present application, the terms "first", "second" and the like are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0046] Under the background of actively promoting clean energy utilization around the world, solar photovoltaic power generation is in a rapid development stage due to its significant advantages such as environmental protection and renewable energy. As a photovoltaic support structure that can adapt to complex terrain, effectively reduce construction cost and be easy to install, flexible photovoltaic support is widely used in many photovoltaic power station constructions.

[0047] In the structure of flexible photovoltaic support, the anchoring assembly plays a key role in connecting the steel strand and other parts of the support, and is a core element to ensure stable operation of the system. At present, the industry generally uses a clamping anchor as an anchoring assembly, and its working principle is to rely on the friction between the clamping piece and the steel strand to achieve fixation.

[0048] However, in the actual outdoor operating environment, this traditional anchoring method has obvious defects. In areas with large wind load, when strong winds hit, the flexible support cable will vibrate strongly under the action of wind force, and the stress on the steel strand will increase sharply. At this time, the friction between the clamping piece and the steel strand cannot withstand such a large external force, and the steel strand is prone to slipping. Once slipping occurs, the stability of the entire flexible photovoltaic support system will be destroyed, which may cause damage to photovoltaic equipment, cause economic losses, and even endanger the safety of surrounding personnel.

[0049] In one embodiment, referring to the drawings attached to the specification Figure 1 , an anchoring assembly provided by the present application is described, which significantly improves the safety and reliability when connected with the steel strand, and can better adapt to different intensity of external force load and complex use environment.

[0050] Referring to the drawings attached to the specification Figure 1 and Figure 2The anchor assembly provided by the application comprises an extrusion anchor 1, a clamping anchor 2 and a sleeve 3. The extrusion anchor 1 is provided with a first installation space 100 penetrating the axial direction, for passing through the steel strand 4. The extrusion anchor 1 can be deformed in the radial direction when subjected to external force, based on the specific material and structure. For example, the extrusion anchor 1 is made of high-strength alloy material, and when the external hydraulic radial force is applied, the extrusion anchor 1 will shrink inwardly, tightly fit the steel strand 4, and make the two fixed as a whole. Compared with the traditional single friction mode, the anchor force between the steel strand 4 and the anchor assembly is greatly improved, and the steel strand 4 is not easy to slip out of the extrusion anchor 1 in the face of strong wind load, severe vibration or sudden external force impact, thereby ensuring the structural integrity of the flexible photovoltaic support.

[0051] In the embodiment, the clamping anchor 2 is provided with a second installation space 200 penetrating the axial direction, for passing through the steel strand 4. The clamping anchor 2 clamps and fixes the steel strand 4 through the internal structure. Optionally, the clamping anchor 2 can adopt an elastic embracing structure, and the elastic component can adaptively adjust the clamping force on the steel strand 4, so as to better adapt to the complex outdoor environment, and a special wear-resistant coating can be used at the part of the clamping anchor 2 contacting the steel strand 4, so as to slow down the wear and prolong the service life.

[0052] More importantly, the sleeve 3 is arranged in the embodiment, and the sleeve 3 is located between the extrusion anchor 1 and the clamping anchor 2, and has a third installation space 300 penetrating the axial direction, thereby providing a smooth passing channel for the steel strand 4.

[0053] When the steel strand 4 bears external force, for example, is subjected to tension under the action of wind load, the sleeve 3 can act as a key medium for force transmission. Since the sleeve 3 is closely connected with the extrusion anchor 1 and the clamping anchor 2, the tension of the steel strand 4 can be evenly dispersed to the extrusion anchor 1 and the clamping anchor 2 at both ends along the sleeve 3.

[0054] It should be noted that if the sleeve 3 is not arranged, when the clamping anchor 2 fails due to reasons such as long-term wear, sudden super-strong external force impact and the like, under the action of the tension of the steel strand 4, the extrusion anchor 1 will lose the constraint and is likely to axially displace to the clamping anchor 2. This not only causes the extrusion anchor 1 to directly impact the clamping anchor 2, so that the structures of the two are damaged, but more seriously, the displacement breaks the original force balance state of the whole anchor system. Because the displacement of the extrusion anchor 1 makes the force of the steel strand 4 at the anchor end uneven, thereby causing the local overload of the support, and finally affecting the stability of the whole flexible photovoltaic support, and even can cause the support to tilt and collapse, thereby causing serious damage to the photovoltaic equipment. In the embodiment, the sleeve 3 is arranged to eliminate the axial displacement risk, and ensure that each anchor component is always in the correct working position.

[0055] In one embodiment, based on the above embodiment, as shown in Figure 3 The extrusion anchor 1 includes a first extrusion member 11, which is constructed in a tubular structure to form a first installation space 100, and the material of the first extrusion member 11 is a plastic material, for example, an engineering plastic alloy commonly used in engineering, which has good plasticity and also has certain strength and toughness. In the actual construction site, a professional hydraulic extrusion device is used to gradually apply radial pressure. As the pressure gradually increases, the inner diameter of the first extrusion member 11 gradually decreases, and the first extrusion member 11 uniformly adheres to the outer periphery of the steel strand 4. In this process, the gap between the first extrusion member 11 and the steel strand 4 continuously decreases until they are in close contact and reach a relatively fixed state.

[0056] Compared with the traditional anchoring device relying on friction or simple mechanical clamping, the fixing method realized by the plastic material deformation in the present application is more stable, can flexibly adjust the adhesion degree according to the actual specifications, surface conditions, and other factors of the steel strand 4, generate all-around and high-strength holding force, and greatly strengthen the connection reliability between the steel strand 4 and the anchoring assembly. On the other hand, since the first extrusion member 11 and the steel strand 4 are in close contact, there is almost no relative displacement between them, which greatly reduces the risk of loosening caused by long-term vibration and temperature changes, ensures the stability of the photovoltaic system during long-term operation, and effectively reduces the maintenance cost in the later period.

[0057] Optionally, a spiral or ring-shaped reinforcing rib is added inside the tubular structure to assist the plastic material in more accurately applying holding force to the steel strand 4 when under pressure without affecting the penetration of the steel strand 4.

[0058] Based on the above content, further, the extrusion anchor 1 also includes an auxiliary holding member 12, which is arranged inside the first extrusion member 11 and also has a fourth installation space 120 penetrating in the axial direction to penetrate the steel strand 4.

[0059] Specifically, in the present embodiment, the steel strand 4 is first penetrated into the fourth installation space 120, and when the anchoring operation is performed, i.e., the radial pressure is applied to the first extrusion member 11, the auxiliary holding member 12 will be subjected to force at the same time. When the inner diameter of the first extrusion member 11 gradually decreases under the action of pressure, the auxiliary holding member 12 also moves synchronously and converts the external force into a pressing force on the steel strand 4, which cooperates with the first extrusion member 11 to apply pressure to the steel strand 4 from multiple directions to form a more stable holding effect.

[0060] In the present embodiment, the type and material of the auxiliary holding member 12 are not limited, and the operator can select different auxiliary holding members 12 according to different application scenarios and engineering requirements.

[0061] For example, the auxiliary gripping member 12 in the drawing is an extrusion spring, which can be dynamically adjusted according to the specific situation of the steel strand 4. The diameter of the steel strand 4 can be slightly different due to manufacturing tolerances or wear after long-term use, and the extrusion spring can adaptively change the gripping force by virtue of its elastic properties. For example, when the steel strand 4 is slightly larger in diameter, the extrusion spring will be further compressed, generating a greater gripping force; when the steel strand 4 is slightly smaller in diameter, the elastic restoring force of the extrusion spring can still ensure close fitting, ensuring that the steel strand 4 has sufficient anchoring force with the anchoring assembly.

[0062] On the contrary, in other embodiments, the auxiliary gripping member 12 can also be an elastic rubber ring or a rubber ring, which will be deformed when the first extrusion member 11 is subjected to radial pressure. Due to the elastic properties of the rubber material itself, it will generate a uniform radial gripping force on the steel strand 4; at the same time, it can also have a certain shock absorption effect, and can absorb part of the energy when the support is subjected to vibration or impact. Optionally, some textures or protrusions are designed on the surface of the rubber ring to increase the friction between the steel strand 4 and the first extrusion member 11.

[0063] In one embodiment, as shown in Figure 2 The clamping anchor 2 includes a first fixed member 21 and a clamping structure 23. The first fixed member 21 is also a tubular structure and has a cavity communicating with both ends of the axis, providing a passage for the steel strand 4 to pass through. The clamping structure 23 is arranged in the cavity, and after the steel strand 4 passes into the first fixed member 21 of the clamping anchor 2, the clamping structure 23 can compress the outer periphery of the steel strand 4 to fix it.

[0064] It should be noted that in this embodiment, the specific form of the clamping structure 23 is not strictly limited. In some conventional and relatively stable photovoltaic projects, a relatively simple mechanical ring clamping structure 23 can basically meet the basic anchoring requirements, while in some harsher photovoltaic projects, a clamping structure 23 that can adaptively adjust the clamping force may be required to dynamically adjust the clamping degree according to the real-time stress of the steel strand 4 and changes in the external environment, ensuring that the steel strand 4 can be firmly fixed in any working condition and ensuring the reliability of the photovoltaic support.

[0065] Meanwhile, in the conventional design, the first fixing member 21 is an integrated tubular structure, which has good integrity and structural strength, and can stably bear the clamping structure 23 and the steel strand 4. However, in some specific cases, the first fixing member 21 is arranged in a split manner, for example, composed of two relatively independent split bodies, and the two split bodies are connected through a connecting member. The two split bodies can be tightly connected to form a stable whole during normal use, so as to ensure that the anchoring process of the steel strand 4 is not affected. In addition, when necessary, the two split bodies can be easily loosened, so as to create very convenient conditions for the installation or replacement of the internal clamping structure 23. For example, when installing the clamping structure 23 for the first time, the operator can easily install the selected clamping structure 23 into the cavity. Or, after long-term use, the clamping structure 23 needs to be replaced due to performance degradation caused by factors such as frequent stress and environmental erosion. Maintenance personnel do not need to disassemble the entire anchoring assembly. They only need to open the connecting member, remove the old clamping structure 23, replace it with a new one, and then tighten it again. The performance of the anchoring assembly can be quickly restored, and the maintenance cost is reduced.

[0066] Further, as shown in Figure 2 and Figure 4 , the clamping anchor 2 further comprises a second fixing member 22, and the first fixing member 21 is located between the sleeve 3 and the second fixing member 22, and the three are arranged along the axial direction. The first fixing member 21 and the second fixing member 22 are respectively provided with corresponding threaded structures 24, so that the two can be fixedly connected through the threaded structures 24. In the actual assembly and installation scene, the operator only needs to align the threads of the first fixing member 21 and the second fixing member 22 according to the standard process, and then perform a rotating operation manually or with the help of a simple tool. The two can be quickly and firmly fixed as a whole to form the overall structure of the clamping anchor 2.

[0067] Similarly, the second fixing member 22 also has a cavity communicating with both ends of the axial direction, and the second fixing member 22 and the first fixing member 21 can jointly form an installation cavity for accommodating the clamping structure 23. Specifically, during the initial assembly stage, the operator can easily put the selected clamping structure 23 into the installation cavity through the opening between the two fixing members. After the installation and placement of the clamping structure 23 are completed, the first fixing member 21 and the second fixing member 22 are fixed by screwing, so that the clamping structure 23 is stably placed between the two fixing members.

[0068] It is worth mentioning that through the arrangement of the first fixing member 21 and the second fixing member 22 in this embodiment, the clamping anchor 2 is designed in a split manner. If the maintenance personnel find that the clamping structure 23 needs to be adjusted or replaced due to performance degradation caused by factors such as long-term stress and environmental erosion during long-term use, the maintenance personnel can quickly disassemble the first fixing member 21 and the second fixing member 22 to directly contact the clamping structure 23 in the installation cavity, and then accurately and efficiently perform maintenance operations.

[0069] Furthermore, the first fixing member 21 has a first limiting part 211 on the side away from the second fixing member 22. Understandably, during normal operation, slight vibrations from the photovoltaic power station equipment itself or wind effects can cause displacement of the steel strand 4. In this case, the first limiting part 211 can restrict the movement of the clamping structure 23 within the mounting cavity, keeping it stable in its original position and preventing it from coming loose. Correspondingly, the second fixing member 22 also has a second limiting part 221 on the side away from the first fixing member 21. The second limiting part 221 prevents the clamping structure 23 from coming loose from the other side. Moreover, the second limiting part 221 on the second fixing member 22 can cooperate with the first limiting part 211 to restrict the displacement of the clamping structure 23 from both sides, ensuring the reliability and safety of the clamping structure 23.

[0070] In one embodiment, please refer to the appendix to the specification based on the above embodiment. Figure 4 and Figure 5 The internal cavity of the first fixing member 21 or the second fixing member 22 is a conical cavity 50. The large-diameter end of the conical cavity 50 is close to the sleeve 3, and the small-diameter end is correspondingly far away from the sleeve 3. At the same time, the external contour of the clamping structure 23 is set as a conical surface contour that matches the conical cavity 50.

[0071] Due to the tension of the steel strand 4, the clamping structure 23 slides steadily along the conical cavity 50 toward the smaller diameter end. As a result, the pressure applied by the clamping structure 23 to the outer periphery of the steel strand 4 gradually increases. This increasing clamping force can effectively and firmly fix the steel strand 4 in the preset position and prevent the steel strand 4 from loosening.

[0072] It should be understood that the conical cavity 50 is located inside the first fixing member 21 or the second fixing member 22, depending on the connection method of the two when they are threaded together. When the first fixing member 21 is fitted inside the second fixing member 22, the conical cavity 50 is located inside the first fixing member 21; conversely, as in the case described in the specification, the second fixing member 22 is fitted inside the first fixing member 21, and the conical cavity 50 is located in the second fixing member 22. When the steel strand 4 bears tension, the clamping structure 23 slides orderly towards the smaller diameter end along the conical cavity 50 with the help of the matching conical surface with the conical cavity 50 of the second fixing member 22.

[0073] Based on the above embodiments, in one embodiment, the clamping structure 23 adopts a split design, including at least two clamping units 231. The outer contour of each clamping unit 231 is adapted to the conical surface of the conical cavity 50, ensuring that the clamping unit 231 can slide smoothly along the conical cavity 50 during operation, avoiding jamming or deviation from the trajectory. On the other hand, the inner surface of the clamping unit 231 can contact the steel strand 4 and provide clamping force. Generally, a toothed surface or similar anti-slip structure is provided on its inner surface to increase the friction between it and the steel strand 4.

[0074] After the steel strand 4 enters the conical cavity 50 from its large-diameter end, it drives the clamping unit 231 to move synchronously along the conical cavity 50. At this time, the clamping unit 231 will undergo radial contraction, which increases the contact pressure between the clamping unit 231 and the steel strand 4, thereby increasing the friction between the clamping unit 231 and the steel strand 4. Furthermore, the contraction of the clamping unit 231 is continuous. As the tension of the steel strand 4 increases, the clamping unit 231 will continue to move towards the small-diameter end of the conical cavity 50, and the clamping force will also continue to increase until the friction generated by the clamping unit 231 on the steel strand 4 can balance the tension of the steel strand 4, at which point the steel strand 4 is completely secured.

[0075] like Figure 5 As shown, there are two clamping units 231, which are inserted into the second fixing member 22 in a wedge shape. Of course, in other embodiments, the number of clamping units 231 or the angle of the wedge can be adjusted. For example, the optimal wedge angle can be determined through simulation experiments so that the clamping unit 231 can generate clamping force in the most effective way when subjected to the tension of the steel strand 4.

[0076] Based on the anchoring components described in the above embodiments, one implementation process for anchoring the steel strand 4 is as follows: First, the clamping anchor 2 is installed at a predetermined position on the steel strand 4 to achieve its initial clamping and positioning function. After the clamping anchor 2 is installed, the sleeve 3 and the compression anchor 1 are fitted onto the corresponding positions on the steel strand 4, and then preparations are made for the compression anchoring work.

[0077] Before using the compression tool to compress the compression anchor 1, precisely insert the assembly of the compression anchor 1 and the steel strand 4 into a specific position within the compression tool. Simultaneously, special attention must be paid to maintaining a reasonable gap between the compression anchor 1 and the wedge anchor. This ensures that the compression anchor 1 and the steel strand 4 can be smoothly inserted into the compression tool, avoiding installation obstacles due to insufficient space, and effectively prevents accidental damage to the sleeve 3 and the wedge anchor during operation, maintaining the integrity of the entire anchoring assembly.

[0078] When the extrusion tool starts to work, the steel strand 4 will be pushed out along the opposite direction together with the extrusion anchor 1 installed thereon. During this dynamic process, the sleeve 3 abutting against the extrusion anchor 1 will move synchronously with the extrusion anchor 1, and under the action of the extrusion tool, the friction and mechanical engagement force between the steel strand 4 and the extrusion anchor 1 gradually increase, and finally the stable fixation of the two is achieved. On the other hand, the pushing force generated in this process also acts on the clamping unit 231, prompting the clamping unit 231 to further press the steel strand 4, and additionally increasing the anchoring reliability of the steel strand 4, so as to improve the effect of the whole system from multiple dimensions, and ensure that the steel strand 4 can maintain a stable anchoring state under long-term stress and complex working conditions.

[0079] In one embodiment, reference is made to the drawings attached hereto Figure 6 According to another aspect of the present application, the present application further provides a flexible photovoltaic support, comprising at least two spaced base 6, at least two anchoring assemblies described above and the steel strand 4.

[0080] The base 6 serves as the root of the whole support and provides support for the remaining components. The two ends of the steel strand 4 are fixed to the adjacent two bases 6 through an anchoring assembly. Through such a connection mode, multiple bases 6 can be continuously connected in series, thereby forming an overall flexible photovoltaic support.

[0081] It can be understood that in the present embodiment, the anchoring assembly mainly comprises the clamping anchor 2, the extrusion anchor 1 and the sleeve 3. First, double anchoring is formed, thereby greatly improving the ability of the steel strand 4 to cope with complex interference such as external tension and vibration. Then, through the arrangement of the sleeve 3, force conduction is effectively formed, avoiding stress accumulation in a local part and improving reliability.

[0082] Further, as shown in Figure 6 Each base 6 comprises a column 61 and a crossbeam 62 arranged on the top of the column 61. In the actual installation scene, one end of the clamping anchor 2 abuts against the side wall of the crossbeam 62, and the force acting on the steel strand 4 can be transmitted to the crossbeam 62 through the clamping anchor 2. The force is dispersed to the column 61 and the working ground through the crossbeam 62, thereby ensuring that the whole structure is balanced, stable and reliable.

[0083] Based on the above, each crossbeam 62 has at least two connection positions along the length direction thereof. It can be understood that the connection position is the point position at which the steel strand 4 and the crossbeam 62 are connected. In some cases, each connection position corresponds to an assembly hole 620 on the crossbeam 62. Generally, the connection positions are uniformly or symmetrically distributed, fully considering the tension balance of the steel strand 4 under stress, so as to ensure that the tension borne by each steel strand 4 can be uniformly dispersed to the crossbeam 62, thereby avoiding the risk of local structure deformation caused by uneven stress.

[0084] In the actual construction process, the number of steel strands 4 corresponds to the number of connection positions and is accurately set. In this way, connection through multiple steel strands 4 is achieved between the two bases 6, which jointly shares the tension and pressure, greatly enhancing the wind stability of the support. On the other hand, the setting of multiple steel strands 4 effectively improves the redundancy of the support. Even if a certain steel strand 4 has performance degradation due to wear, corrosion or accidental impact during long-term use, the remaining steel strands 4 can still maintain the overall mechanical balance of the support by relying on their own strength, ensuring that the support does not fail instantly, and gaining valuable time for subsequent maintenance and replacement.

[0085] For a flexible photovoltaic support, the way the steel strands 4 are arranged has an important influence on the stability and stress performance of the support. As shown in the figure, the base 6 includes a first side wall 601 and a second side wall 602 arranged opposite to each other.

[0086] Based on the above, in one embodiment, the first side wall 601 and the second side wall 602 are respectively provided with assembly holes 620 penetrating the width direction of the base 6, and the steel strands 4 are connected to the base 6 by penetrating the assembly holes 620. In this way, the structure is relatively simple, and it is convenient for processing and installation,

[0087] In some cases, relying solely on the assembly holes 620 to fix and connect the steel strands 4 may not meet the specific strength or durability requirements, so in another embodiment, a sleeve structure 63 is arranged between the first side wall 601 and the second side wall 602. The sleeve structure 63 is hollow designed, and the steel strands 4 can sequentially penetrate the assembly hole 620 on the first side wall 601, the sleeve structure 63 and the assembly hole 620 on the second side wall 602, and finally form a connection with the base 6. In this way, the connection strength between the steel strands 4 and the base 6 is enhanced to some extent, while providing better guiding, supporting and protecting effects, which is conducive to the installation and formation of the flexible photovoltaic support and the later maintenance.

[0088] Specifically, as Figure 7 shown in the figure, in this application, the assembly hole 620 is arranged on the cross beam 62 of the base 6, and in other embodiments, the position of the assembly hole 620 can also be changed to adapt to different structural design requirements. At the same time, it should be noted that in the preferred embodiment of the present application, the first side wall 601 and the second side wall 602 are two opposite side walls on the cross beam 62, but in actual application, the skilled person can make targeted adjustments according to different base structures.

[0089] It should be noted that the above embodiments can be freely combined as needed. The above are only the preferred embodiments of the application, and it should be pointed out that for those skilled in the art, without departing from the principles of the application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the application.
