Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic tracking systems, in particular to a main beam splicing shrink tube of a photovoltaic tracking system. Background Art

[0002] The core components of the current photovoltaic tracking system, the main beam and transmission rod, are often long because they need to adapt to installation sites of different sizes and the need to track the sun. Therefore, in order to achieve the extension of length, these components are mostly spliced. Specifically, the extension of the length of the main beam and the transmission rod mainly depends on the application of sleeves and opposing bolts. When two main beams or two transmission rods need to be connected together, a special sleeve is required, which is placed at the junction of the two components and then tightened with opposing bolts to ensure a stable connection between them.

[0003] However, the connection of the sleeve and the opposing bolts alone is not enough to meet the stability and accuracy requirements of the photovoltaic tracking system. In order to further improve the strength and stability of the connection, it is necessary to set positioning keys and keyways inside the slide and outside the main beam or transmission rod. The design of these positioning keys and keyways allows the two connection parts to be accurately aligned when spliced, reducing performance losses caused by installation errors.

[0004] However, there are some problems with the existing methods of extending the length between the main beams or transmission rods of photovoltaic tracking systems. First, it requires additional sleeves and opposing bolts, which undoubtedly increases the complexity and cost of the system. Secondly, the matching of the positioning key and the keyway also requires precise processing, which not only increases the processing steps, but also may lead to an increase in processing costs. More seriously, these additional processing steps may cause environmental pollution, which runs counter to the development concept of green energy. Utility Model Content

[0035] Next, the shrink tube body and the first tube body are plugged and fixed by a riveting assembly.

DETAILED DESCRIPTION

[0054] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0056] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, the meaning of "plurality" is two or more.

[0057] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0058] like Figure 1-15 As shown, a photovoltaic tracking system main beam splicing shrink tube includes a plug-in portion 1 and a receiving portion 2;

[0059] The plug-in portion 1 comprises a first tube body 11, and a plurality of first mounting holes 12 are formed at one side of the first tube body 11 and are distributed at equal intervals;

[0060] The receiving portion 2 includes a second tube body 21, a connecting tube body 22 and a shrinking tube body 23 which are connected in sequence. The diameter of the second tube body 21 is the same as that of the first tube body 11. The outer diameter of the connecting tube body 22 gradually decreases from the end connected to the second tube body 21 to the end connected to the shrinking tube body 23. The diameter of the shrinking tube body 23 is smaller than the diameter of the first tube body 11.

[0061] A plurality of second mounting holes 24 are formed on one side of the shrinkable tube body 23 and are equidistantly distributed. The shrinkable tube body 23 is inserted and arranged on one side of the first tube body 11 close to the first mounting hole 12.

[0062] A plurality of the second mounting holes 24 and the corresponding first mounting holes 12 are each provided with a riveting assembly 3 for riveting the first tube body 11 and the shrink tube body 23 .

[0063] First, insert the shrinkable tube 23 at one end of the receiving part 2 into one end of the first tube 11 of the plug-in part 1. This step is simple and direct, and does not require complicated operations or additional accessories. The design that the diameter of the shrinkable tube 23 is smaller than the diameter of the first tube 11 can ensure the plug-in fit between the shrinkable tube 23 and the first tube 11, thereby achieving preliminary splicing.

[0064] Next, the shrinkable tube 23 and the first tube 11 are plugged and fixed by the riveting assembly 3. The riveting assembly 3 passes through the first mounting hole 12 on the first tube 11 and the second mounting hole 24 on the shrinkable tube 23, and then uses the riveting technology to firmly connect them without the need for additional sleeves and opposing bolts. At the same time, it also avoids the processing of positioning keys and keyways and additional processing steps such as welding, threaded connection, etc., thereby greatly simplifying the operation process and reducing processing costs.

[0065] In addition, it is in line with the development concept of green energy. Since no additional processing steps and accessories are required, energy consumption and waste generation are reduced, which is beneficial to environmental protection. At the same time, the simple connection method also reduces maintenance costs and improves overall economic benefits.

[0066] In summary, the utility model achieves efficient, environmentally friendly and economical pipe connection through the plug-in setting of the shrink pipe body 23 and the riveting fixation of the riveting assembly 3, and is particularly suitable for occasions where quick and easy connection of the pipe body is required.

[0067] To further illustrate, the riveting assembly 3 includes a nail body 31 and a riveting portion 32 sleeved on the nail body 31;

[0068] A breaking ring groove 311 is centrally formed on the outer edge surface of the nail body 31, and a plurality of annular anti-slip grooves 312 are equidistantly formed on both sides of the breaking ring groove 311 on the outer edge surface of the nail body 31;

[0069] The nail body 31 includes a nail head end and a nail tail end, and the riveting portion 32 is sleeved on the breaking ring groove 311 and one side close to the nail head end of the nail body 31;

[0070] The nail head end of the nail body 31 is sequentially penetrated by the first mounting hole 12 and the corresponding second mounting hole 24. When the nail tail end of the nail body 31 is pulled toward the outer tube surface of the first tube body 11 by external force and the breaking ring groove 311 is broken by external force, the side of the nail body 31 close to the nail head end and the riveted part 32 are riveted to the first mounting hole 12 and the corresponding second mounting hole 24, and the broken part of the breaking ring groove 311 is exposed outside the first mounting hole 12.

[0071] To further explain, the riveting part 32 includes a riveted tube 321, and a limited position seat 322 is protrudingly provided on the outer tube surface of the riveted tube 321;

[0072] The nail head end of the nail body 31 is sequentially penetrated by the first mounting hole 12 and the corresponding second mounting hole 24, and the limiting seat 322 abuts against the outer tube surface of the first tube body 11;

[0073] When the nail tail end of the nail body 31 is pulled toward the outer tube surface of the first tube body 11 by external force, and the breaking ring groove 311 is broken by external force, the rivet tube 321 is compressed and contracted to form a plurality of overlapping convex rings 323, and the overlapping convex rings 323 abut against the inner tube surface of the shrinkable tube body 23.

[0074] The riveting process of the riveting assembly 3 is as follows:

[0075] First, if Fig.15 As shown in a, the nail head end of the nail body 31 and the rivet tube 321 of the riveting part 32 are inserted into the first mounting hole 12 and the corresponding second mounting hole 24 together, wherein the stopper 322 of the riveting part 32 abuts against the outer tube surface of the first tube body 11. This ensures that the riveting assembly 3 is in the correct position, and is ready for the subsequent riveting process.

[0076] Next, if Fig.15 As shown in bc, the riveting device 4 clamps the nail tail end portion of the nail body 31 exposed on the outer tube surface of the first tube body 11 from the outside, and then pulls the nail body 31 and pushes the limit seat 322. In this process, the rivet tube 321 is subjected to pressure and begins to deform. Due to the material properties of the rivet tube 321, it will produce multiple shrinkages of the inner tube surface of the tube body 23 during the deformation process, forming a preliminary fixing effect. The deformed rivet tube 321 will also press into the multiple annular anti-skid grooves 312 on the nail body 31. This design realizes an anti-skid connection, ensuring that under vibration or impact conditions, there will be no relative sliding between the rivet tube 321 and the nail body 31.

[0077] In addition, since the stopper 322 is arranged in a truncated cone shape and the maximum diameter of the stopper 322 is greater than or equal to the diameter of the superimposed convex ring 323, the tensile strength after riveting is further improved. This means that even under a large tensile force, the stopper 322 can maintain a stable contact with the outer tube surface of the first tube body 11.

[0078] Finally, if Fig.15 As shown in d, when the pulling force of the riveting device 4 gradually increases, the nail body 31 will break at the breaking ring groove 311. This is a safety design, which is intended to prevent the exposed nail body 31 from causing greater damage to the entire riveting assembly 3 in extreme cases. At the same time, this design also avoids the subsequent step of shearing the exposed nail body 31, thereby improving work efficiency.

[0079] In general, the riveting assembly 3 of the utility model is very cleverly designed in the riveting process, which not only achieves a firm connection, but also takes safety and work efficiency into consideration, and is highly practical.

[0080] Further description, the first embodiment of the riveting assembly 3: Figure 7-10 The limiting seat 322 is arranged in a truncated cone shape, and the maximum diameter of the limiting seat 322 is consistent with the diameter of the superimposed convex ring 323 .

[0081] Further description, the second embodiment of the riveting assembly 3: Figure 11-14 As shown, the limiting seat 322 is arranged in a truncated cone shape, and the maximum diameter of the limiting seat 322 is greater than the diameter of the superimposed convex ring 323 .

[0082] The design of the stopper 322 can further improve the tensile strength after riveting, which means that even under a large tensile force, the stopper 322 can maintain a stable contact with the outer tube surface of the first tube body 11.

[0083] In summary, the riveting assembly in this application is designed for outdoor construction of photovoltaic tracking systems and has two implementation methods to adapt to different scenarios and needs.

[0084] Specifically, the riveting assembly includes a nail body 31 and a riveting portion 32. The nail body 31 is used to connect with the main beam splicing shrink tube of the photovoltaic tracking system, and the riveting portion 32 is used to implement the riveting process to ensure a firm connection between the components.

[0085] Importantly, the design of the riveting assembly 3 in the present application takes into account the different wall thicknesses of the main beam splicing shrink tube. By using different types of nail bodies 31 and riveting parts 32, it is possible to rivet main beams with different wall thicknesses, thereby ensuring the stability and reliability of the connection.

[0086] Further explanation, a first embodiment of a photovoltaic tracking system main beam splicing shrink tube: Figure 1-2 As shown, the first tube body 11, the second tube body 21, the connecting tube body 22 and the shrinking tube body 23 are all made of octagonal tubes, and the octagonal tubes include eight outer annular surfaces connected in sequence;

[0087] One side of the first tube body 11 is provided with four groups of the first mounting holes 12, and the four groups of the first mounting holes 12 are respectively arranged with an outer annular surface spaced apart;

[0088] Four groups of the second mounting holes 24 are formed on one side of the shrinkable tube body 23 , and the four groups of the second mounting holes 24 are respectively arranged at intervals of one of the outer annular surfaces.

[0089] The four groups of the first mounting holes 12 and the four groups of the second mounting holes 24 are arranged in a one-to-one correspondence.

[0090] Specifically, the shrinkable tube 23 at one end of the receiving portion 2 is inserted into one end of the first tube 11 of the plug-in portion 1, and then the first embodiment or the second embodiment of the riveting assembly 3 is selected according to actual needs to complete the plug-in fixation of the shrinkable tube 23 and the first tube 11.

[0091] Further explanation, a second embodiment of a photovoltaic tracking system main beam splicing shrink tube: Figure 3-4 As shown, the first tube body 11, the second tube body 21, the connecting tube body 22 and the shrinking tube body 23 are all made of quadrilateral tubes, and the quadrilateral tubes include four outer annular surfaces connected in sequence;

[0092] One side of the first tube body 11 is provided with four groups of the first mounting holes 12, and the four groups of the first mounting holes 12 are respectively provided on the four outer annular surfaces of the first tube body 11;

[0093] Four groups of the second mounting holes 24 are opened on one side of the shrinkable tube body 23 , and the four groups of the second mounting holes 24 are respectively arranged on the four outer annular surfaces of the shrinkable tube body 23 .

[0094] The four groups of the first mounting holes 12 and the four groups of the second mounting holes 24 are arranged in a one-to-one correspondence.

[0095] The difference from the first embodiment is the shape design of the tube body and the number design of the first mounting holes 12 and the second mounting holes 24. The riveting process of the riveting assembly 3 is the same and will not be described in detail here.

[0096] Further explanation, a second embodiment of a photovoltaic tracking system main beam splicing shrink tube: Figure 5-6 As shown, the first tube body 11, the second tube body 21, the connecting tube body 22 and the shrinking tube body 23 are all made of round tubes;

[0097] Two groups of the first mounting holes 12 are formed on one side of the first tube body 11, and the two groups of the first mounting holes 12 are symmetrically arranged on the first tube body 11, and the first mounting holes 12 are in a long strip shape;

[0098] Two groups of the second mounting holes 24 are formed on one side of the shrinkable tube body 23 , and the two groups of the second mounting holes 24 are symmetrically arranged on the shrinkable tube body 23 .

[0099] The two groups of the first mounting holes 12 and the two groups of the second mounting holes 24 are arranged in a one-to-one correspondence.

[0100] The difference from the first and second embodiments is the shape design of the tube body and the number design of the first mounting holes 12 and the second mounting holes 24. The riveting process of the riveting assembly 3 is the same and will not be described in detail here.

[0101] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
