Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic power generation, in particular to a mounting clamp and a mounting structure of a photovoltaic module. BACKGROUND

[0002] At present, when the photovoltaic power generation is applied, a plurality of photovoltaic modules are generally rigidly connected together by fastening components such as bolts to form a whole, and then the whole is installed on a building. For example, in the installation of a sewage pool of a sewage treatment plant, a cable is used for fixing. However, a problem is brought about: the cable has excellent flexibility, so that the cable is prone to wind pressure deformation in severe weather such as strong wind. The whole structure of the plurality of photovoltaic modules rigidly connected together results in that the position of a single photovoltaic module lacks adaptability, so that the photovoltaic module cannot meet the requirement of planar deformation caused by the wind pressure deformation of the cable, and the photovoltaic module is damaged and broken, which greatly affects the service life and reliability. SUMMARY

[0003] Therefore, it is necessary to provide a mounting clamp, so that the photovoltaic module can effectively adapt to the deformation force caused by the wind pressure deformation of the cable, so that the photovoltaic module has excellent energy absorption capacity, thereby avoiding extrusion damage and breakage, and improving the service life and reliability.

DETAILED DESCRIPTION

[0028] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the protection scope of the present application.

[0029] It should be noted that when an element is referred to as being "fixedly connected", "arranged" or "disposed" on another element, it can be directly on the other element or there can be a middle element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be a middle element; the specific manner in which an element is fixedly connected to another element can be achieved by existing technology, and will not be described here again, and a threaded connection is preferably used.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0031] In the present application, "first" and "second" do not represent specific quantities and orders, but are only used for name differentiation.

[0032] In order to achieve the purpose of energy saving and consumption reduction, in the sewage treatment plant sewage pool, aquaculture farm aquaculture pool and other applications, photovoltaic module 400 for solar power generation often uses cable 500 as an installation carrier for fixing. That is, the two ends of the cable 500 are fixed on the objects around the pool, and the middle part of the cable 500 is suspended across the pool overhead, and a plurality of photovoltaic modules 400 are installed side by side on the cable 500 to receive sunlight. The installation clamp 10 in the present technical solution is used to fix the photovoltaic module 400 on the cable 500, and forms a "flexible" connection between the photovoltaic module 400 and the cable 500, so as to better cope with the adverse effects of cable 500 deformation.

[0033] As shown in Figures 2 to 4 The installation clamp 10 of an embodiment of the present application includes: a clamping assembly 100 adapted to be connected with a photovoltaic module 400; a cable clamp 200 adapted to be connected with a cable 500; and a sliding connector 300, one end of which is connected with the clamping assembly 100, and the other end of which is movably connected with the cable clamp 200.

[0034] The installation clamp 10 described above, when in use, can first connect and fix the clamping assembly 100 with the photovoltaic module 400, then assemble and fix the cable clamp 200 with the cable 500, and finally connect the clamping assembly 100 with the cable clamp 200 through the sliding connector 300. Since the sliding connector 300 and the cable clamp 200 are in a movable connection relationship, when the cable 500 is bent and deformed due to wind and other weather forces, the relative movement of the sliding connector 300 and the cable clamp 200 can effectively adapt to the pulling force in the direction of wind load, and can also absorb the longitudinal deformation force caused by the wind pressure deformation of the cable 500, thereby making the photovoltaic module 400 have good deformation adaptation capability and avoiding bending and breaking, so as to greatly improve the working safety and service life of the photovoltaic module 400, and reduce the operation and maintenance cost.

[0035] At least two photovoltaic modules 400 are constructed as an installation unit. The following describes the case of two photovoltaic modules 400, which are rigidly connected and fixed by traditional buckling plates, supporting plates 120 and bolt assemblies. At this time, the two photovoltaic modules 400 are in the same plane and cannot move or rotate relative to each other. The cable 500, which plays a role in bearing and fixing, is usually a bundle structure of a plurality of steel wire ropes. In order to facilitate transportation and installation, the cable 500 itself has excellent bending ability, that is, it has a certain deformation ability. This makes the cable 500 deformed when the wind blows in bad weather. At this time, when the resistance stress between the two rigidly connected photovoltaic modules is less than the external force generated by the deformation of the cable 500, the photovoltaic modules 400 will be squeezed and damaged, or even broken, which seriously affects the safety of the photovoltaic modules 400. In view of this, the installation clamp 10 of the present application is movably connected with the cable clamp 200 through the sliding connecting piece 300. When the cable 500 deforms, the relative displacement of the sliding connecting piece 300 and the cable clamp 200 can well offset the destructive force exerted by the deformation of the cable 500, thereby effectively avoiding the damage caused by the destructive force acting on the photovoltaic modules 400.

[0036] Please continue to refer to Figure 3 In an optional embodiment, the clamping assembly 100 includes a pressing block 110, a supporting plate 120 and a first fastening assembly 130. The pressing block 110 is connected with the supporting plate 120 through the first fastening assembly 130 and is spaced apart to form a clamping cavity for clamping and fixing the photovoltaic module 400. The first fastening assembly 130 can connect and fix the pressing block 110 and the supporting plate 120 to effectively clamp and fix the photovoltaic module 400. Moreover, during the clamping operation, by adjusting the tightness of the first fastening assembly 130, the size of the clamping cavity (specifically the distance between the pressing block 110 and the supporting plate 120) can be flexibly changed, so that photovoltaic modules 400 of different thicknesses can be installed and fixed, and the application range is wide and the application performance is strong.

[0037] Specifically, in this embodiment, the first fastening assembly 130 is a bolt and nut assembly, and the corresponding positions on the pressing block 110 and the supporting plate 120 are respectively provided with threaded holes. The bolt is threadedly connected with the nut after penetrating through the two threaded holes. This connection method is simple and labor-saving, has high connection strength and good reliability, and is convenient for the installation, disassembly and replacement of the photovoltaic module 400.

[0038] It can be understood that the first fastening assembly 130 can also be other parts or mechanisms for fixing in the prior art, such as adhesives, straps and hoops, which are also within the protection scope of the present application.

[0039] In view of the fact that some photovoltaic components 400 adopt glass base material, when the photovoltaic components 400 are in contact with the metal-based pressing block 110 and the supporting plate 120, the problem of slipping and not being tightly fixed is likely to occur, which is prone to cause the photovoltaic components 400 to be loosened under force. Please continue to refer to Figure 3 , based on this, in a further technical solution, the side of the pressing block 110 facing the clamping cavity is provided with a first anti-loosening part 600, and the side of the supporting plate 120 facing the clamping cavity is provided with a second anti-loosening part 700, and the first anti-loosening part 600 and the second anti-loosening part 700 are both in limiting cooperation with the photovoltaic component 400. By setting the first anti-loosening part 600 and the second anti-loosening part 700, the connection between the pressing block 110 and the supporting plate 120 and the photovoltaic component 400 is more firm and reliable.

[0040] In this embodiment, the first anti-loosening part 600 and the second anti-loosening part 700 are both adhesive layers; or the first anti-loosening part 600 and the second anti-loosening part 700 are both concave-convex structures; or the first anti-loosening part 600 is an adhesive layer and the second anti-loosening part 700 is a concave-convex structure; or the first anti-loosening part 600 is a concave-convex structure and the second anti-loosening part 700 is an adhesive layer. In this way, during actual installation operation, a person skilled in the art can design and manufacture the first anti-loosening part 600 and the second anti-loosening part 700 as adhesive layers or concave-convex structures according to actual needs, thereby improving the bonding force and relative frictional resistance with the surface of the photovoltaic component 400, and further improving the connection strength between the pressing block 110 and the supporting plate 120 and the photovoltaic component 400.

[0041] It can be understood that the above-mentioned adhesive layer can be selected from glue, double-sided tape and the like; and the above-mentioned concave-convex structure can be selected from various types of anti-slip lines, arrayed protruding structures and the like.

[0042] Please continue to refer to Figure 3 and Figure 4 In another optional embodiment, the cable clamp 200 includes a first clamping body 210, a second clamping body 220, and a second fastening assembly 230, the first clamping body 210 is provided with a first recess 211, the second clamping body 220 is provided with a second recess 221 opposite to the first recess 211, and the first clamping body 210 is connected with the second clamping body 220 through the second fastening assembly 230, so that the first recess 211 and the second recess 221 cooperate to form a sliding hole, and the sliding connection piece 300 is slidably arranged in the sliding hole. Thus, the sliding hole formed by the cooperation of the first recess 211 and the second recess 221 not only can be effectively connected with the sliding connection piece 300, simplifying the connection structure and operation mode and being beneficial to improving the installation operation efficiency, but also the sliding connection piece 300 can freely slide in the sliding hole, so as to effectively resist the deformation force of the cable 500 through displacement change, thereby ensuring the safety of the photovoltaic component 400.

[0043] As shown in Figures 4 to 6 particular, the main body of the first clamping component 210 is a clamping block, and one end surface of the clamping block is integrally connected with an L-shaped block. One end of the L-shaped block is connected with the clamping block, and the other end of the L-shaped block extends out to the second clamping component 220. The width of the end of the L-shaped block connected with the clamping block is smaller than the width of the clamping block, so that the L-shaped block cooperates with the clamping block to form a U-shaped groove, which is the first recess 211. In addition, the main body of the second clamping component 220 is also a clamping block, and the only difference is that one end surface of the clamping block is integrally connected with another small rectangular block. The width of the rectangular block is smaller than the width of the clamping block, and one side surface of the rectangular block is flush with one side surface of the clamping block, and the other side surface cooperates with the end surface of the clamping block to form a stepped notch, which is the second recess 221. In this way, when the first clamping component 210 and the second clamping component 220 are connected through the second fastening assembly 230, the opposite side surfaces of the first clamping component 210 and the second clamping component 220 are tightly fitted, and at the same time, the end surface of the free end of the L-shaped block and the side surface of the rectangular block are also tightly fitted, so that the U-shaped groove and the stepped notch combine to form a sliding hole with a rectangular cross section.

[0044] Please continue to refer to Figure 3 In an optional embodiment, the sliding connector 300 includes a sliding rod 310 slidably arranged in the sliding hole, and a first connecting rod 320 and a second connecting rod 330 arranged at intervals. One end of the first connecting rod 320 is connected with the supporting plate 120, the other end of the first connecting rod 320 is connected with one end of the sliding rod 310, one end of the second connecting rod 330 is connected with the supporting plate 120, the other end of the second connecting rod 330 is connected with the other end of the sliding rod 310, and the first connecting rod 320, the second connecting rod 330, the sliding rod 310 and the supporting plate 120 form a cavity 800. At this time, the sliding rod 310, the first connecting rod 320 and the second connecting rod 330 constitute a U-shaped member, and the opening end of the U-shaped member is welded and fixed with the bottom surface of the supporting plate 120, so that the connection strength is high.

[0045] In order to make the sliding resistance of the sliding connector 300 relative to the cable clamp 200 smaller, the sliding is more smooth and easy, the cross-sectional area of the part of the free end of the L-shaped block inserted into the cavity 800 needs to be smaller than the cross-sectional area of the cavity 800, and the sliding rod 310 is gap-fitted with the hole wall of the sliding hole. At this time, the cavity wall of the cavity 800 and the hole wall of the sliding hole interfere with the L-shaped block and the sliding rod 310 as little as possible, so that the frictional resistance is small, and the relative sliding can be ensured to be more smooth.

[0046] In an optional embodiment, the second fastening assembly 230 comprises a bolt and a nut, the first clamping body 210 is provided with a first threaded hole, the second clamping body 220 is provided with a second threaded hole opposite to the first threaded hole, and the bolt is arranged in the first threaded hole and the second threaded hole and is threadedly connected with the nut. The bolt and the nut are connected with the first threaded hole and the second threaded hole, the connection mode is simple to operate, the connection strength is high, and the installation, disassembly, replacement, use convenience and post-maintenance convenience of the cable clamp 200 are improved.

[0047] It can be understood that, in order to improve the installation strength and the performance of the installation clamp 10 in resisting external force, the above-mentioned first fastening assembly 130 and the second fastening assembly 230 can be simultaneously installed in two groups or more groups, and the number can be selected according to the actual needs of the workers, which will not be described here.

[0048] Please continue to refer to Figure 3 Further, the first clamping body 210 is provided with a first arc-shaped clamping part 212, the second clamping body 220 is provided with a second arc-shaped clamping part 222, and the first arc-shaped clamping part 212 and the second arc-shaped clamping part 222 are adapted to the shape of the cable 500. At this time, when the first clamping body 210 and the second clamping body 220 are assembled and connected, the first arc-shaped clamping part 212 and the second arc-shaped clamping part 222 cooperate to form a clamping hole which is adapted to the shape and size of the cable 500, so that the cable clamp 200 and the cable 500 are combined more closely, and the clamping strength and the clamping reliability are improved.

[0049] It can be understood that, by adjusting the tightness of the second fastening assembly 230, the distance between the first arc-shaped clamping part 212 and the second arc-shaped clamping part 222 is adjustable, so that the clamping requirements of the cable 500 with different shapes and sizes can be met, and the application range of the installation clamp 10 can be greatly improved.

[0050] As Figure 1As shown, in another aspect, the application also provides a mounting structure of a photovoltaic module 400, which comprises a cable 500, two photovoltaic modules 400, a flip clamp 900 connected between opposite ends of the two photovoltaic modules 400, and two mounting clamps 10 as described above, one of the mounting clamps 10 connects the cable 500 and one end of one of the photovoltaic modules 400 away from the flip clamp 900, and the other mounting clamp 10 connects the cable 500 and one end of the other photovoltaic module 400 away from the flip clamp 900, and the two photovoltaic modules 400 can be flipped and swung relative to each other through the flip clamp 900. When the cable 500 is deformed, the mounting clamp 10 enables the photovoltaic module 400 to slide relative to the cable 500, and the flip clamp 900 also synchronously enables the adjacent two photovoltaic modules 400 to flip and swing, and under the combined action of the two movements, the deformation impact caused by the deformation of the cable 500 can be better absorbed, the ability of the photovoltaic module 400 to cope with the deformation of the cable 500 can be improved, and the safety and reliability of the photovoltaic module 400 during installation and use can be ensured, and the photovoltaic module 400 can be prevented from being damaged.

[0051] Of course, for some photovoltaic power generation occasions with large demand, the above mounting structure can be used as a unit, and a plurality of units are connected with each other and mounted on the cable 500.

[0052] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description simple, all possible combinations of the technical features in the above-mentioned embodiments are not described, but as long as the combinations of the technical features do not exist contradictory, they should be considered as the scope of the present application.

[0053] The above-mentioned embodiments only express several embodiments of the present application, and the description is more specific and detailed, but it should not be understood as a limitation on the scope of the patent. It should be pointed out that for ordinary skilled in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which are within the scope of the present application. Therefore, the scope of protection of the present application should be subject to the appended claims.
