Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic power stations, and in particular to a photovoltaic bracket connection device. Background Art

[0002] With the development of the photovoltaic industry, the construction scale of photovoltaic power stations has increased year by year. There are more and more connection brackets in photovoltaic power stations, and the types of connection brackets are also increasing. The connection bracket is a device that installs photovoltaic modules to the supporting structure. The connection bracket can have good adaptability and can be designed according to the curvature of the site terrain. It can be widely used in various photovoltaic power stations, such as rooftop photovoltaic power stations, roof and rooftop photovoltaic power stations, outdoor photovoltaic power stations outside the roof, mountain photovoltaic power stations, etc.

[0003] The connecting bracket includes a cable body assembly for installing a photovoltaic assembly and a supporting structure for supporting the cable body assembly. The cable body assembly includes a cable body and an anchor crimped on the cable body. The supporting structure includes an end column on which the cable body assembly is installed and a column structure for connecting the end column. The cable body assembly is connected to the end column through the anchor, thereby supporting the cable body assembly.

[0004] The cable body needs to be terminally connected to the bracket, and the rod of the component needs to be connected to the bracket. The main terminal connection methods are:

[0005] 1. Crimp type anchor.

[0006] 2. Bolt anchor.

[0007] 3. Bolt and nut anchors.

[0008] 4. Composite anchor of bolt anchor and bolt and nut anchor.

[0009] The crimping anchor is a common terminal connection method, which connects the cable body and the anchor by crimping them together.

[0010] At present, crimping anchors are commonly used on site to connect the cable body and the steel structure. However, crimping anchors have the following disadvantages:

[0011] The length of the cable body needs to be measured and cut according to the on-site conditions. The extrusion spring is put on the cable body and inserted into the extrusion anchor sleeve. The extrusion springs must not be stacked. The two ends of the cable body and the compression tube are pressed by special hydraulic tools. After the crimping is completed, anti-corrosion grease is applied to the screw thread of the bolt section of the extrusion anchor sleeve. The fixed end anchor is connected to a section of the extrusion anchor through threads, and the other end of the extrusion anchor is also connected to the tensioning anchor through threads. The anchors at both ends are connected to the end columns through pins. The cable body and the extrusion anchor need to be crimped with professional tools. The crimping result is irreversible and the adjustment space is extremely small. Before crimping, it needs to be accurately cut according to the actual requirements of the site. The cable body cannot be used if it is too long or too short. If one end is crimped unqualified, it will cause the entire cable body and the extrusion anchor to be scrapped, causing a large amount of property losses. After the construction is completed, secondary tensioning cannot be performed and later maintenance cannot be performed. Utility Model Content

[0012] The main purpose of the utility model is to provide a photovoltaic bracket connection device, which can flexibly adjust the application length of the cable body, has a large adjustment range, and can perform secondary tensioning after the construction is completed, which is convenient for later maintenance.

[0013] In order to achieve the above-mentioned purpose, according to one aspect of the utility model, a photovoltaic bracket connection device is provided, including an end connection assembly, a cable body connector and a cable body, and one end of the end connection assembly connected to the cable body connector is provided with a wire passing groove, the cable body connector is passed through the wire passing groove, and the cable body connector is wrapped around the cable body and fixedly connected to the cable body.

[0014] Furthermore, the cable body connector includes a first section located at a first side of the cable groove and a second section located at a second side of the cable groove, the first section and the second section are wound around and fix the cable body at the same time, and the winding directions of the first section and the second section are the same.

[0015] Furthermore, the first section and the second section are alternately arranged and spirally wound on the cable body along the length direction of the cable body.

[0016] Furthermore, at least one tightening member is provided at the winding ends of the first section and the second section.

[0017] Furthermore, the bottom wall of the cable groove is an arc-shaped structure that is high in the middle and low at both ends along the winding direction of the cable body connecting piece.

[0018] Furthermore, friction-increasing particles are arranged between the cable-body connecting piece and the cable body; and / or, the cable-body connecting piece and the cable body are made of the same material.

[0019] Furthermore, the end connection assembly includes a first connection member and a second connection member connected in sequence, the first connection member includes a first arcuate connection portion, the second connection member includes a second arcuate connection portion, and the first arcuate connection portion and the second arcuate connection portion are cross-connected.

[0020] Furthermore, the end connection assembly further includes an end connection plate, and the first connection member further includes a connection ear plate arranged at the end of the first arc-shaped connection portion, and the connection ear plate is hinged to the end connection portion.

The friction force is used to meet the tensile requirements of the cable body, and the connection is more secure, avoiding the problem of unreliable connection between the cable body and the photovoltaic support connection device. In addition, since the cable body connector is wrapped around the cable body and connected to the cable body by winding, the length of the cable body can be adjusted by adjusting the winding position of the cable body connector on the cable body.

[0029] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] See also Figure 1 to Figure 2 As shown, the utility model provides a photovoltaic bracket connection device, including an end connection assembly, a cable body connector 1 and a cable body 2, and one end of the end connection assembly connected to the cable body connector 1 is provided with a wire passing groove 3, the cable body connector 1 is passed through the wire passing groove 3, and the cable body connector 1 is wrapped around the cable body 2 and fixedly connected to the cable body 2.

[0031] By providing a wire groove 3 on the end connection component and inserting the cable body connector 1 into the wire groove 3, the cable body connector 1 is wound around the cable body 2 and fixedly connected to the cable body 2, so that the cable body 2 and the cable body connector 1 are connected by the friction force generated by the winding of the two. The friction force is used to meet the tensile resistance requirements of the cable body 2, and the connection is more firm, avoiding the problem of unreliable connection between the cable body 2 and the photovoltaic bracket connection device. In addition, since the cable body connector 1 is wound around the cable body 2 and connected to the cable body 2 by winding, the length of the cable body 2 can be adjusted by adjusting the winding position of the cable body connector 1 on the cable body 2. The adjustment process is reversible and the adjustment space is large, which can better meet the length adjustment requirements of the cable body 2. In addition, when connecting the cable body connector 1 and the cable body 2, the winding position of the cable body connector 1 on the cable body 2 can be adjusted according to the actual requirements on site, so that when the cable body 2 is too long or too short, it can be adapted by adjusting the winding position, which can avoid the scrapping problem caused by inappropriate length of the cable body 2 and reduce costs. After the construction is completed, when the length of the cable body 2 needs to be adjusted, the cable body connector 1 can be untied from the cable body 2, and then the winding position of the cable body connector 1 on the cable body 2 can be readjusted, so as to facilitate secondary tensioning and make later maintenance convenient and reliable.

[0032] During the use of the photovoltaic support connection device, the cable body does not need to be cut off and can be adjusted according to the on-site installation requirements. If the initial winding position does not meet the length requirement, it can be manually disassembled directly and a suitable installation position can be re-selected, which can effectively reduce cable waste.

[0033] In one embodiment, the cable body connector 1 includes a first section 4 located on the first side of the cable groove 3 and a second section 5 located on the second side of the cable groove 3. The first section 4 and the second section 5 are simultaneously wound around and fixed to the cable body 2, and the winding directions of the first section 4 and the second section 5 are the same.

[0034] In this embodiment, the cable-body connector 1 adopts a rope structure, passes through the wire groove 3, and the cable-body connector 1 passes through both ends of the wire groove 3 to form a first section 4 and a second section 5, wherein the first section 4 is wrapped around the cable body 2 from the radial first side of the rope, and the second section 5 is wrapped around the cable body 2 from the radial second side of the rope. The first section 4 and the second section 5 are wrapped around the cable body 2 at the same time, which can form a larger contact area with the cable body 2, and the first section 4 and the second section 5 are wrapped along the spiral direction, which can further increase the friction force generated by the first section 4 and the second section 5 wrapped around the cable body 2, effectively preventing the cable-body connector 1 from detaching from the cable body 2, and improving the stability and reliability of the connection between the two.

[0035] In one embodiment, the first section 4 and the second section 5 can also be wound around the cable body 2 along opposite winding directions, so that the first section 4 and the second section 5 are crossed during the winding process, and the friction between the cable body connector 1 and the cable body 2 is further increased by utilizing the characteristics of the cross-winding of the first section 4 and the second section 5.

[0036] Since the cable body connector 1 and the cable body 2 are fixedly connected by winding, they can be quickly installed on site without any special tools and can be completed by one person. If the cable body becomes loose at a later stage, secondary reinforcement can be conveniently performed.

[0037] In one embodiment, the first section 4 and the second section 5 are alternately arranged and spirally wound on the cable body 2 along the length direction of the cable body 2 .

[0038] In this embodiment, the first section 4 and the second section 5 are alternately staggered along the length direction of the cable body 2, so that the first section 4 and the second section 5 will not cross each other, and both can always be in winding contact with the cable body 2, which can increase the winding contact area between the cable body connector 1 and the cable body 2. In addition, the first section 4 and the second section 5 can cover the cable body 2, thereby forming a better covering effect on the cable body 2, and increasing the friction force formed by the winding between the first section 4 and the second section 5 and the cable body 2.

[0039] In one embodiment, the first section 4 and the second section 5 have the same length, so that the winding lengths of the first section 4 and the second section 5 on the cable body 2 are the same, which can form a more balanced winding friction force.

[0040] In one embodiment, at least one tightening member is provided at the winding ends of the first section 4 and the second section 5. By providing the tightening member at the ends of the first section 4 and the second section 5, the ends of the first section 4 and the second section 5 can be compressed, further increasing the friction between the first section 4 and the second section 5 and the cable body 2, and preventing the cable body connector 1 from being separated from the cable body 2.

[0041] In one embodiment, the cable body connector 1 adopts a flat steel belt structure, which can form a larger contact area with the cable body 2, thereby generating a greater friction force during the winding process, thereby improving the winding friction force between the cable body connector 1 and the cable body 2.

[0042] The cable body connecting member 1 may also be made of a round steel wire rope, or other rope-like structures or belt-like structures made of the same material as the cable body 2 .

[0043] In one embodiment, the bonding force between the cable body connector 1 and the cable body 2 can be further enhanced by gluing.

[0044] In one embodiment, the bottom wall of the cable groove 3 is an arc-shaped structure with a high middle and low ends along the winding direction of the cable body connector 1 .

[0045] In this embodiment, the bottom of the wire groove 3 is set to an arc-shaped structure with a decreasing height from the middle to both ends along the winding direction of the cable body connector 1, which can make the bending structure of the cable body connector 1 smoother, reduce the friction between the cable body connector 1 and the bottom wall of the wire groove 3, and improve the service life of the cable body connector 1. In addition, since the cable body connector 1 is wound in the wire groove 3, the arc-shaped structure of the wire groove 3 can also make the first section 4 and the second section 5 of the cable body connector 1 closer at the outlet position, and it is easier to generate a self-locking force in the process of winding the cable body 2, which can further improve the connection reliability between the cable body connector 1 and the cable body 2.

[0046] In one embodiment, friction-increasing particles are provided between the cable body connector 1 and the cable body 2. By adding friction-increasing particles, the friction between the cable body connector 1 and the cable body 2 after the cable body connector 1 and the cable body 2 are entangled can be further increased, and the cable body connector 1 and the cable body 2 can be more effectively prevented from being separated.

[0047] In one embodiment, the cable body connector 1 is made of the same material as the cable body 2. The cable body connector is made of the same material as the cable body, is less susceptible to electrochemical corrosion, and has a more reliable connection.

[0048] In one embodiment, the end connection assembly includes a first connection member 6 and a second connection member 7 connected in sequence, the first connection member 6 includes a first arcuate connection portion, the second connection member 7 includes a second arcuate connection portion, and the first arcuate connection portion and the second arcuate connection portion are cross-connected.

[0049] In this embodiment, by connecting the first arc-shaped connecting portion and the second arc-shaped connecting portion in a cross shape, the arc-shaped connecting portion can be used to achieve adjustment in various directions, thereby solving the problem of height difference of the column.

[0050] In one embodiment, the end connection assembly further includes an end connection plate 8 , and the first connection member 6 further includes a connection ear plate 9 disposed at the end of the first arc-shaped connection portion, and the connection ear plate 9 is hinged to the end connection plate 8 .

[0051] In this embodiment, the end connecting plate 8 and the first connecting member 6 are detachably connected by bolts, which can facilitate the installation and disassembly of the connection structure between the end connecting plate 8 and the first connecting member 6, and the operation is simpler.

[0052] In one embodiment, the end connecting plate 8 may also be fixed to the first connecting member 6 by welding.

[0053] In one embodiment, the end connection assembly further includes an adjusting connection member 10 , and the second connection member 7 further includes a connecting ear plate 9 arranged at the end of the second arc-shaped connection portion, and the connecting ear plate 9 is hinged to the adjusting connection member 10 .

[0054] In this embodiment, by providing an adjustable connector 10 between the second connector 7 and the cable body 2, the length of the adjustable connector 10 can be adjusted to adapt to the length of the cable body 2, making on-site installation more convenient.

[0055] In one embodiment, the end connection assembly further includes a cable body adapter 11 , the cable body adapter 11 has a wire groove 3 , and a side of the cable body adapter 11 away from the wire groove 3 has an opening, and the opening is hinged to the adjustment connector 10 .

[0056] In this embodiment, one end of the adjusting connector 10 is detachably connected to the second connector 7 through a high-strength bolt, and the other end is detachably connected to the cable body adapter 11 through a bolt, so that the adjusting connector 10 can be easily replaced. When making a connection, several adjusting connectors 10 of different lengths can be selected, and then the adjusting connector 10 of a suitable length can be selected according to the needs during the installation process, so that the length of the cable body 2 can be easily adapted. The operation is simpler, and the chord length installation can be achieved quickly, which improves the chord length construction efficiency. In the process of later maintenance, secondary tensioning can be performed by changing the winding position of the cable body connector 1 on the cable body 2, or by replacing the adjusting connector 10. The adjustment is more flexible, which can effectively avoid the problem of a decrease in the overall stiffness of the structure caused by extreme weather, which affects the stable and safe operation of the power station.
