Abstract
Description
Technical Field
[0001] This utility model relates to the field of photovoltaic support technology, and in particular to a connection structure between a U-shaped water tank and a crossbeam of a photovoltaic support. Background Technology
[0002] In photovoltaic (PV) mounting systems, the water trough 2' is a crucial component, serving not only as a roof drainage system but also providing essential support and fixation for the PV modules. However, in traditional installation methods, due to the lack of pre-installed mounting holes or other fixing structures on the crossbeam 1' (such as a square tube crossbeam), installing the water trough typically requires drilling holes on-site and then securing it with bolts, nuts, and other fasteners. This installation method not only compromises the structural integrity of the crossbeam and the U-shaped water trough, reducing their stability, but also involves a cumbersome on-site drilling process, significantly impacting construction efficiency.
[0003] One improvement is, such as Figure 1 As shown, the water tank 2' is fixed to the square tube beam 1' by an upper clamp, a lower clamp, and several locking components. However, this clamp assembly 3' has many parts, which not only increases material costs but also prolongs construction time, causing inconvenience to the installation and maintenance of the photovoltaic bracket. Utility Model Content
[0004] The purpose of this utility model is to provide a connection structure between the U-shaped water tank and the crossbeam of a photovoltaic bracket, which reduces the number of parts, lowers material costs, shortens construction time, and ensures that the connection structure has high stability.
[0005] To achieve the above objectives, the solution of this utility model is: a connection structure between a U-shaped water tank and a crossbeam of a photovoltaic support, comprising:
[0006] The crossbeam is a profile structure with grooves on its main surface.
[0007] U-shaped water tank, which is erected above the crossbeam;
[0008] The U-shaped clamp serves as a connector for connecting the U-shaped water tank and the crossbeam. The two arms of the U-shaped clamp have mounting holes that correspond to the grooves on the crossbeam.
[0009] T-bolts, as fasteners, cooperate with the grooves on the crossbeam and the mounting holes on the Z-shaped clamps to lock the Z-shaped clamps onto the crossbeam, thus connecting the U-shaped water tank to the crossbeam.
[0010] Furthermore, the groove on the crossbeam extends along the length of the main body, and the groove has lateral openings on both sides.
[0011] Furthermore, the groove on the crossbeam has a T-shaped cross section.
[0012] Further, the middle part of the U-shaped bracket is a holding part for holding the U-shaped sink, and the middle part of the U-shaped bracket extends to two sides to form a mounting part, the mounting part is parallel to the surface of the beam, and the mounting part is provided with a mounting hole corresponding to the groove of the beam.
[0013] Further, the holding part of the middle part of the U-shaped bracket is in a shape suitable for the upper surface of the U-shaped sink.
[0014] Further, the T-shaped bolt comprises a head and a screw rod, the head is a polygon with a long side and a short side, the head is rotated in the measuring groove to be clamped in the groove, and the screw rod is used to pass through the mounting hole of the U-shaped bracket and cooperate with the nut to lock the U-shaped bracket on the beam.
[0015] Further, the groove on the beam is in a U-shaped structure at the connection with the main body.
[0016] Further, the U-shaped structure comprises a horizontal side and two vertical sides, the first vertical side and the second vertical side are located at two ends of the horizontal side and extend in the same direction from the two ends of the horizontal side.
[0017] Further, the beam is a hollow structure.
[0018] Further, the cross section of the beam is a rectangle, and at least one side of the rectangle is provided with a groove.
[0019] After the above scheme is adopted, the beneficial effects of the present application are as follows:
[0020] The beam with the groove is adopted, and cooperates with the T-shaped bolt, so that the stable installation and fixation of the U-shaped sink and the beam are realized. This design can not only reduce the number of required parts, but also effectively reduce the material cost, so that the whole connection structure is more economical and affordable. Compared with the traditional connection mode, the close cooperation of the groove and the T-shaped bolt greatly improves the connection stability between the U-shaped sink and the beam, and ensures the stability and reliability of the photovoltaic support under various environmental conditions.
[0021] In addition, the present application also has the advantages of simple construction and convenient operation. The construction personnel do not need to perform complex operations such as on-site punching, but only need to slide the T-shaped bolt into the groove of the beam and rotate to fix, then install the U-shaped bracket and tighten the nut to complete the installation, so that the construction time is greatly shortened and the work efficiency is improved.

[0034] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
[0035] This utility model provides a connection structure between the U-shaped water tank and the crossbeam of a photovoltaic support, such as... Figures 2 to 7 As shown, it includes a crossbeam 1, a U-shaped water trough 2, a Z-shaped clamp 3, and several T-bolts 4.
[0036] The photovoltaic support structure described in this invention features a sloping roof, which can be either a gable roof or a single-sided sloping roof. The crossbeam 1 is installed parallel to the roof ridge, providing support and fixation; while the U-shaped water trough 2 is placed at an angle along the side of the sloping roof and erected above the crossbeam 1 to collect and guide rainwater and other liquids.
[0037] The beam 1 used in this design is a rectangular, hollow profile, as referenced. Figure 4However, this design is not an absolute requirement. It can be flexibly adjusted according to actual application needs. The main advantage of the hollow structure is that it helps to significantly reduce the overall weight, thereby improving the handling and installation efficiency of photovoltaic brackets; at the same time, the hollow design can also effectively improve material utilization, reduce costs and benefits, and make the manufacturing of photovoltaic brackets more economical and efficient.
[0038] More importantly, the surface of the main body 11 of the crossbeam 1 is provided with a groove 12, for reference. Figures 2 to 4 The groove 12 extends along the length of the main body 11, and has lateral openings on both sides to facilitate the entry of the head of the T-bolt 4. Furthermore, the cross-section of the groove 12 is T-shaped. The groove 12 can mate with the T-bolt 4, fixing a portion of the T-bolt within the groove 12.
[0039] The U-shaped clamp 3 serves as a connector, used to connect the U-shaped water tank 2 and the crossbeam 1. Specifically, as... Figure 3 and Figure 7 As shown, the central part of the Z-shaped clamp 3 is a clamping part 31 that surrounds the U-shaped water tank 2. The clamping part 31 adapts to the undulations 311 of the upper surface of the U-shaped water tank 2, thus perfectly fitting the upper surface of the U-shaped water tank 2 and effectively preventing slippage that may occur under the impact of water flow or wind, greatly improving the overall stability. The central part of the Z-shaped clamp 3 extends to both sides to form a mounting part 32 parallel to the surface of the crossbeam 1. The mounting part 32 has mounting holes 33 corresponding to the grooves 12 of the crossbeam 1. The mounting holes 33 allow the screws of the T-bolts 4 to pass through, and then by tightening the nuts 5 and other fasteners, a firm connection is achieved between the Z-shaped clamp 3, the U-shaped water tank 2 and the crossbeam 1, providing solid support and protection for the overall structure of the photovoltaic bracket.
[0040] refer to Figure 6 and Figure 7 T-bolts 4, as fasteners, mate with the grooves 12 on the crossbeam 1 and the mounting holes 33 on the U-shaped clamps 3, locking the U-shaped clamps 3 onto the crossbeam 1, thus connecting the U-shaped water tank 2 to the crossbeam 1. Specifically, as... Figure 6 As shown, the head of the T-bolt 4 is a parallelepiped, with one set of parallel sides being the long sides and the other two sets being the short sides. The bolt has threads that can mate with the nut 5.
[0041] The T-bolt 4 is fitted into the groove 12 on the inclined beam as follows: the head of the T-bolt 4 is slid into the groove 12 from the side, and then rotated at a certain angle so that its head is locked in the groove 12. The screw of the T-bolt 4 is outside the groove 12. The screw can pass through the mounting hole 33 on the Z-shaped clamp 3 and be tightened by the nut 5 or other locking device, thereby firmly locking the Z-shaped clamp 3 onto the crossbeam 1, achieving a stable connection between the U-shaped water tank 2 and the crossbeam 1.
[0042] As a further improvement to the structure, the connection between the groove 12 on the crossbeam 1 and the main body 11 is a Z-shaped structure 13. Specifically, as... Figure 4 and Figure 5 As shown, the Z-shaped structure 13 includes a horizontal side 131 and two vertical sides. The first vertical side 132 and the second vertical side 133 are located at both ends of the horizontal side 131 and extend parallel to each other in the same direction. During processing, these components are integrally formed with the main body 11. Compared with traditional sharp bends, this Z-shaped transition structure can effectively disperse stress and significantly reduce stress concentration, thus making the stress distribution at the connection more uniform and reasonable. This design not only significantly improves the fatigue resistance of the profile during use and enhances the structural stability, but also greatly improves the overall load-bearing capacity and reliability of the photovoltaic support profile, providing a guarantee for the safe and efficient operation of the photovoltaic support.
[0043] The assembly method of the U-shaped water tank 2 and the crossbeam 1 of this utility model is as follows:
[0044] The pre-fixed crossbeam 1 (usually fixed to the column) has its side with the groove 12 facing upwards. Then, the U-shaped water tank 2 with its opening facing upwards is placed on the crossbeam 1 and adjusted to a suitable position according to actual needs.
[0045] Next, install the T-bolt 4. Slide the head of the T-bolt 4 into the groove 12 from the side and rotate it at a certain angle so that its head is stuck in the groove 12. Here, it is necessary to ensure that one T-bolt 4 is installed on each side of the U-shaped water tank 2 to correspond to the mounting holes 33 of the two arms of the Z-shaped clamp 3 respectively.
[0046] Next, place the Z-shaped clamp 3, so that the screw of the T-bolt 4 passes through the mounting holes 33 on both arms of the Z-shaped clamp 3;
[0047] Finally, tighten the nut 5 onto the threaded rod of the T-bolt 4. As the nut 5 is gradually tightened, the Z-shaped clamp 3 will be firmly pressed onto the U-shaped water tank 2 and the crossbeam 1. This completes all the assembly steps.
[0048] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments.
