Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic brackets, and particularly to a solar photovoltaic panel support frame that is convenient for installation. Background Art

[0002] With the growing global demand for renewable energy, solar energy, as a clean and sustainable energy form, has received extensive attention. As a key device for directly converting sunlight into electrical energy, solar photovoltaic panels have been widely used in households, commercial buildings, and even public facilities. However, the effective utilization of solar photovoltaic panels not only depends on their own performance but is also closely related to the design of the support frame. The support frame not only needs to ensure that the photovoltaic panel can be firmly installed in a predetermined position but also needs to have good weather resistance and a certain degree of aesthetics.

[0003] Existing solar photovoltaic panel support frames mainly adopt a frame structure composed of multiple angle steels. These angle steels are precisely designed to form stable crossbeams and longitudinal beams to provide the necessary supporting force. However, this traditional design has some obvious deficiencies. First, the connection between each crossbeam and longitudinal beam usually needs to be completed with the help of fasteners such as bolts, which means that cumbersome manual operations must be carried out during the installation process. This not only increases the time cost of installation but also raises the labor intensity. Especially in large-scale installation projects, this problem is particularly prominent. Second, since the support frame exists in a dispersed state before installation, that is, each component needs to be transported to the installation site separately and then assembled one by one, it is easy to lose or damage during transportation and handling, bringing additional inconvenience to the construction. In addition, the complex installation process may also lead to uneven installation quality, affecting the final use effect and safety. Summary of the Invention

[0004] In view of this, the present invention provides a solar photovoltaic panel support frame that is convenient for installation, which can overcome the deficiencies of the existing solar photovoltaic panel support frame that requires manually tightening the bolts between each crossbeam and longitudinal beam during installation, resulting in more time cost, greater labor intensity, troublesome operation, affecting the installation efficiency, and the support frame existing in a dispersed state before installation, being inconvenient for transportation and handling.

[0005] A solar photovoltaic panel support frame that is convenient for installation, comprising a cross beam, a first longitudinal beam, a second longitudinal beam, a rotating telescopic rod, a handle, a first clamping block and a first spring. The cross beam is symmetrically provided with a first mounting hole and a second mounting hole respectively. The first longitudinal beam and the second longitudinal beam are respectively rotatably connected to both ends of the cross beam, and both the first longitudinal beam and the second longitudinal beam are provided with a third mounting hole and a storage groove.

[0007] Further explanation, it also includes a base, and the base is provided with insertion holes for the ends of the first longitudinal beam and the second longitudinal beam to be inserted.

[0008] Further explanation, it also includes a rotating block and a hinge.

The second clamping blocks are symmetrically slidably connected to the mounting blocks, and the second clamping blocks are stuck in the second grooves. The second spring connects the mounting block and the second clamping block.

[0010] Further explanation, it also includes a sliding rod, a locking block, a third clamping block and a third spring. The sliding rods are symmetrically slidably connected in the cross beam. The locking block is connected to one end of the sliding rod. Locking grooves are provided at the rotational connection positions of the first longitudinal beam and the second longitudinal beam with the cross beam, and the locking block is stuck in the locking grooves. The third clamping block is connected to the other end of the sliding rod, and the third clamping block is stuck in the third groove. The third spring connects the third clamping block and the cross beam.

[0011] Further explanation, it also includes a rotating rod, a fourth clamping block and a fourth spring.

The fourth clamping block is slidably connected in the second mounting hole, and the fourth clamping block is stuck in the annular groove.

[0012] Further explanation, it also includes an arc convex block. A transverse groove is provided on the side of the fourth clamping block. The arc convex block is connected in the annular groove, and the arc convex block is stuck in the transverse groove.

[0013] The beneficial effects of the present invention are as follows: 1.

The cooperation of the fourth clamping block and the annular groove can fix the position of the photovoltaic panel. These multiple locking mechanisms can effectively prevent the loosening or falling off of components during use, ensuring the safety and reliability of the support frame and extending its service life.

[0031] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, in which presently preferred embodiments of the invention are shown. However, the invention can be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided for thoroughness and completeness and fully convey the scope of the invention to those skilled in the art.

[0032] Embodiment: A solar photovoltaic panel support frame that is convenient for installation, as Figures 1-4As shown in the figure, it includes a cross beam 1, a first longitudinal beam 2, a second longitudinal beam 3, a rotating telescopic rod 6, a handle 7, a first clamping block 8, a first spring 9, an arc-shaped magnet 10 and a base 11. Two first mounting holes 101 and two second mounting holes 102 are symmetrically formed on the cross beam 1, and the extending direction of the first mounting hole 101 is perpendicular to the extending direction of the second mounting hole 102. The two ends of the cross beam 1 are respectively rotatably connected with a first longitudinal beam 2 and a second longitudinal beam 3, and the length of the first longitudinal beam 2 is greater than that of the second longitudinal beam 3. Third mounting holes 4 and receiving grooves 5 are formed on both the first longitudinal beam 2 and the second longitudinal beam 3. A rotating telescopic rod 6 is rotatably connected in each receiving groove 5. The rotating telescopic rod 6 is made of iron, and a first groove 601 is formed on the rotating telescopic rod 6. The handle 7 is connected to the rotating telescopic rod 6. A first clamping block 8 is slidably connected in each third mounting hole 4, and the first clamping block 8 can be stuck in the first groove 601 to fix the position of the rotating telescopic rod 6. In this way, the connection between two first longitudinal beams 2 or two second longitudinal beams 3 can be completed through the rotating telescopic rod 6. First springs 9 are connected between the first clamping block 8 and the first longitudinal beam 2 and the second longitudinal beam 3 respectively. An arc-shaped magnet 10 is connected in each receiving groove 5, and the arc-shaped magnet 10 can adsorb and fix the rotating telescopic rod 6 by magnetic force. The base 11 is used for connecting with the ground, and a jack 1101 for inserting the ends of the first longitudinal beam 2 and the second longitudinal beam 3 is formed at the top of the base 11, so that the cross beam 1, the first longitudinal beam 2 and the second longitudinal beam 3 can be fixed on the ground.

[0033] As Figure 2 , Figure 5 and Figure 6 shown in the figure, it further includes a rotating block 12 and a hinge 13. A rotating block 12 is rotatably connected in each first mounting hole 101, and two third grooves 1201 are symmetrically formed on the rotating block 12. The hinge 13 is formed by hinging a plurality of hinge blocks 1301 to each other, and the hinge blocks 1301 at both ends of the hinge 13 are respectively connected with adjacent two rotating blocks 12, so that the connection between two cross beams 1 can be completed through the cooperation of the rotating block 12 and the hinge 13.

[0034] As Figure 7 and Figure 8 shown in the figure, it further includes a connecting rod 14, a mounting block 15, a second clamping block 16 and a second spring 17. Two connecting rods 14 are symmetrically connected to the cross beam 1, and second grooves 1401 are symmetrically formed on the connecting rods 14. Mounting blocks 15 are connected to the ends of the first longitudinal beam 2 and the second longitudinal beam 3 close to the cross beam 1. The shape of the mounting block 15 is U-shaped, and two second clamping blocks 16 are symmetrically and slidably connected to the inner wall of the mounting block 15. The second clamping block 16 can be stuck in the second groove 1401, and a second spring 17 is connected between the second clamping block 16 and the mounting block 15.

[0035] As Figures 9-11As shown, it also includes a sliding rod 18, a locking block 19, a third clamping block 21 and a third spring 22. The sliding rod 18 is slidably connected to both ends of the interior of the crossbeam 1. One end of the sliding rod 18 is connected to the locking block 19. A locking groove 20 is provided at the rotational connection between the first longitudinal beam 2 and the second longitudinal beam 3 and the crossbeam 1, and the locking block 19 can be stuck in the locking groove 20, thereby locking the relative position between the first longitudinal beam 2 and the second longitudinal beam 3 and the crossbeam 1. The other end of the sliding rod 18 is connected to the third clamping block 21, and the third clamping block 21 is stuck in the third groove 1201. The third spring 22 is wound around the outside of the sliding rod 18, and the two ends of the third spring 22 are respectively connected to the third clamping block 21 and the crossbeam 1.

[0036] like Figures 12-14 As shown, it also includes a rotating rod 24, a fourth clamping block 26, a fourth spring 27 and an arc-shaped protrusion 29. The back side of the photovoltaic panel body 23 is symmetrically rotatably connected to the rotating rod 24, and the rotating rod 24 corresponds one-to-one to the second mounting hole 102. A cross groove is opened at the end of the rotating rod 24 away from the photovoltaic panel body 23, which is convenient for manually twisting the rotating rod 24 with a screwdriver, and an annular groove 25 is opened in the middle of each rotating rod 24. A fourth clamping block 26 is slidably connected in each second mounting hole 102, and the fourth clamping block 26 can be stuck in the annular groove 25, so that the photovoltaic panel body 23 can be fixed on the beam 1. The two ends of the fourth spring 27 are respectively connected to the fourth clamping block 26 and the beam 1, and a transverse groove 28 is opened on the side of each fourth clamping block 26. An arc-shaped protrusion 29 is connected in each annular groove 25, and the arc-shaped protrusion 29 is stuck in the transverse groove 28, so that the rotating rod 24 can be axially locked.

[0037] Initially, if Figure 6 As shown, the bending direction of the hinge 13 is parallel to the radial direction of the beam 1. Under the action of the rotating block 12 and the hinge 13, all the beams 1 can be rolled into a bundle to form a whole. The arc magnet 10 attracts the rotating telescopic rod 6 by magnetic force to prevent it from escaping from the storage slot 5 during transportation, which is convenient for transportation and handling. The third clamping block 21 is not aligned with the third groove 1201, the third spring 22 is in a compressed state, and the locking block 19 is also not aligned with the locking groove 20. First, install an appropriate amount of the base 11 at the specified position, and then Figure 2As shown, multiple crossbeams 1 are horizontally expanded, and then the handle 7 is pulled to rotate and expand the rotating telescopic rod 6 by 90 degrees, separating the rotating telescopic rod 6 from the arc magnet 10. At this time, the rotating telescopic rod 6 is perpendicular to the crossbeam 1. Then, the handle 7 is pulled to extend the rotating telescopic rod 6. When the rotating telescopic rod 6 contacts the first latch 8, it will squeeze the first latch 8 to retract, and the first spring 9 is compressed. Until the first groove 601 on the rotating telescopic rod 6 aligns with the first latch 8, the first spring 9 will return to its original state and drive the first latch 8 to pop out and lock in the first groove 601. In this way, the connection between adjacent two first longitudinal beams 2 and adjacent two second longitudinal beams 3 can be completed through the rotating telescopic rod 6; then the first longitudinal beam 2 and the second longitudinal beam 3 can be rotated towards the direction close to the connecting rod 14. Under the connection action of the rotating telescopic rod 6, all the first longitudinal beams 2 and the second longitudinal beams 3 will rotate synchronously, driving the mounting blocks 15 and the second latches 16 thereon to rotate. When the second latch 16 contacts the connecting rod 14, the connecting rod 14 will squeeze the second latch 16 to retract, and the second spring 17 is compressed. When the second latch 16 aligns with the second groove 1401 on the connecting rod 14, the second spring 17 will return to its original state, driving the second latch 16 to pop out and lock in the second groove 1401, so as to initially limit the positions between the first longitudinal beam 2 and the second longitudinal beam 3 and the crossbeam 1, preventing the first longitudinal beam 2 and the second longitudinal beam 3 from rotating randomly. At this time, it can also ensure that the locking block 19 and the locking groove 20 are in an aligned state; then the rotating block 12 can be rotated by 90 degrees, driving the hinge 13 to rotate by 90 degrees, so that the bendable direction of the hinge 13 is parallel to the axial direction of the crossbeam 1. At this time, multiple crossbeams 1 can be locked, so that the two crossbeams 1 cannot move closer to or away from each other. At the same time, the third groove 1201 on the rotating block 12 will rotate to align with the third latch 21, and the third spring 22 will return to its original state, driving the third latch 21, the sliding rod 18 and the locking block 19 to move towards the direction close to the rotating block 12, so that the third latch 21 is inserted into the third groove 1201, and the locking block 19 is inserted into the locking groove 20, so as to lock the positions between the first longitudinal beam 2 and the second longitudinal beam 3 and the crossbeam 1, preventing the first longitudinal beam 2 and the second longitudinal beam 3 from rotating and ensuring the stability between the crossbeam 1, the first longitudinal beam 2 and the second longitudinal beam 3. Then, the ends of the first longitudinal beam 2 and the second longitudinal beam 3 can be inserted into the jacks 1101 on the base 11 to complete the installation work of the entire solar photovoltaic panel support frame;Finally, when installing the photovoltaic panel body 23, the rotating rod 24 can be directly inserted into the second mounting hole 102. When the rotating rod 24 contacts the fourth locking block 26, it will squeeze the fourth locking block 26 to retract, and the fourth spring 27 will be compressed. When the annular groove 25 on the rotating rod 24 is aligned with the fourth locking block 26, the fourth spring 27 will return to its original state, driving the fourth locking block 26 to pop out and snap into the annular groove 25, so as to initially limit the rotating rod 24 and the photovoltaic panel body 23. Subsequently, rotate the rotating rod 24 by ninety degrees, which can drive the arc-shaped convex block 29 to rotate and snap into the horizontal groove 28, thereby locking the rotating rod 24 and the photovoltaic panel body 23, and quickly completing the installation of the photovoltaic panel body 23.

[0038] The technical principle of the embodiments of the present invention has been described above in conjunction with specific embodiments. These descriptions are only for explaining the principle of the embodiments of the present invention and cannot be construed in any way as a limitation on the protection scope of the embodiments of the present invention. Based on the explanations herein, those skilled in the art can think of other specific embodiments of the embodiments of the present invention without creative efforts, and these embodiments will fall within the protection scope of the embodiments of the present invention.
