[0027] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific embodiments.

[0028] In order to save manpower and improve efficiency, as an embodiment of the utility model, as shown in Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 A photovoltaic support connecting structure for reducing the calculation length of C-shaped purlin, the utility model discloses a support beam 1, support frame 2 and fixed plate 11, the fixed plate 11 is connected with the fixed plate 11 on the outer wall one side of support beam 1 upper end screw, the fixed plate 11 is internally provided with the mounting hole 15 of rectangular array distribution, the embedded groove 16 is set up on the inner wall of mounting hole 15 both sides, the support frame 2 is set up on the both sides outer wall of fixed plate 11, the support frame 2 both sides outer wall is equipped with top holding block 24, and the support seat 21 is installed on the one side outer wall of support frame 2, and the movable hole 22 is set up in the inside of support seat 21, and the screw rod 23 is movably installed in the inside of movable hole 22.

[0029] When using, support beam 1, fixed plate 11 and purlin body 12 can be used as the main support structure, can provide stable support for subsequent photovoltaic panel installation, mounting hole 15 can provide space for the installation of fixed bolt 13, so that the installation position of fixed bolt 13 can be adjusted, the installation position precision requirement between purlin body 12 and fixed plate 11 is reduced, and the subsequent dismounting and installation efficiency of purlin body 12 is ensured to be low, top holding block 24 can be driven to move in embedded groove 16, and top holding block 24 can be pressed and extruded to fixed bolt 13 after fixed bolt 13 fixes purlin body 12, so that fixed bolt 13 is fixed in mounting hole 15, and the position stability of fixed bolt 13 and purlin body 12 is improved.

[0030] In order to fix the use position, exemplarily, as Figure 3As shown, purlin bodies 12 are provided on both outer walls of the fixing plate 11. Fixing bolts 13 are provided inside the purlin bodies 12 and the mounting holes 15, and the purlin bodies 12 are connected to the fixing plate 11 through the fixing bolts 13.

[0031] During use, the fixing bolts 13 ensure a tight connection between the purlin body 12 and the fixing plate 11. During the operation of the photovoltaic system, the load borne by the purlin body 12 can be effectively transferred to the fixing plate 11 and the support beam 1, ensuring the stability and safety of the structure. In addition, the use of fixing bolts 13 allows for easy disassembly and replacement of the purlin body 12.

[0032] To maintain structural strength, for example, such as Figure 4 As shown, the upper and lower outer walls of the top support block 24 are equipped with fitting blocks 25. The inner wall of the fitting groove 16 and the outer wall of the fitting block 25 are both designed in a rectangular shape, and the fitting block 25 is located inside the fitting groove 16.

[0033] In use, the top holding block 24 can ensure horizontal movement inside the mounting hole 15 through the fitting block 25 and the fitting groove 16, keeping the movement trajectory of the top holding block 24 under control, and the fitting block 25 and the fitting groove 16 can maintain the connection strength between the top holding block 24 and the fixing plate 11, ensuring the stability of the top holding block 24 in holding the fixing bolt 13.

[0034] To drive movement, for example, such as Figure 3 As shown, fixing seats 14 are installed on both outer walls of the fixing plate 11. The fixing seats 14 have screw holes inside, and the screw 23 is threaded into the screw holes.

[0035] In use, by rotating the screw 23, the relative position and distance between the support frame 2 and the fixed plate 11 can be changed, thereby pushing the support frame 2 to move and driving the top holding block 24 to move inside the mounting hole 15, maintaining the pressing force of the top holding block 24 on the fixing bolt 13, and ensuring that the fixing bolt 13 is in a stable position inside the mounting hole 15.

[0036] For support and fixation, exemplarily, such as Figure 4 As shown, the top support block 24 adopts a rectangular shape design. The size of the top support block 24 is smaller than the size of the mounting hole 15, and the top support block 24 is located inside the mounting hole 15.

[0037] In use, the top holding block 24 can move inside the mounting hole 15 until the top holding block 24 contacts the outer wall of the fixing bolt 13 and is used to hold and fix the fixing bolt 13. When the fixing bolt 13 needs to be disassembled later, the operator manually flips the screw 23 and disassembles the top holding block 24 to expose the mounting hole 15.

[0038] To maintain support strength, for example, such asFigure 2 As shown, the fixing plate 11 adopts an L-shaped design and is in contact with the purlin body 12.

[0039] In use, the L-shaped design allows the fixing plate 11 to better contact the purlin body 12, increasing the contact area with the purlin body 12 and thus improving the stability of the connection. The L-shaped design also provides some lateral support for the purlin body 12.

[0040] In use, the fixing plate 11 is connected to one side of the upper outer wall of the support beam 1 by screws, and the purlin body 12 is placed on both sides of the fixing plate 11. According to the installation requirements and the position of the mounting holes 15 on the fixing plate 11, the position of the purlin body 12 is roughly adjusted. Due to the presence of the mounting holes 15, the accuracy requirements of the installation position between the purlin body 12 and the fixing plate 11 can be reduced.

[0041] Pass the fixing bolt 13 through the purlin body 12 and the mounting hole 15 of the fixing plate 11, tighten the fixing bolt 13 with a wrench, and rotate the screw 23. Since the screw 23 is threaded into the screw hole inside the fixing seat 14, rotating the screw 23 will change the relative position and distance between the support frame 2 and the fixing plate 11. The support frame 2 will move with the rotation of the screw 23 and drive the top support block 24 to move inside the mounting hole 15.

[0042] The top holding block 24 moves horizontally within the fitting groove 16 via the upper and lower fitting blocks 25, keeping the movement trajectory controlled. When the top holding block 24 moves to contact the outer wall of the fixing bolt 13, the screw 23 continues to rotate, so that the top holding block 24 presses against the fixing bolt 13, ensuring that the fixing bolt 13 is held and fixed inside the mounting hole 15, and restricting the movement of the fixing bolt 13 within the fixing hole.
