Description

Technical Field

[0001] This utility model belongs to the technical field of line connection brackets, specifically relating to an adjustable photovoltaic line access bracket. Background Technology

[0002] The proportion of new energy sources used is gradually increasing. Most new energy sources eventually need to be converted into electricity for use. Photovoltaic power generation is an important new energy source. Its main structural component is the photovoltaic panel. The photovoltaic panel can convert light energy into electrical energy, and then transmit the electrical energy to the power grid through the connection line for use.

[0003] With the upgrading of photovoltaic technology, many rotatable photovoltaic mounting brackets have emerged on the market to improve the efficiency of photovoltaic panels. These brackets can drive the photovoltaic panels to rotate with the sun, ensuring that the photovoltaic panels can absorb solar energy to the maximum extent. However, during the rotation of the photovoltaic panels on these mounting brackets, the connecting lines will also rotate. To avoid insufficient connection line length, which could cause the photovoltaic panels to be unable to rotate or the connection lines to break, a section of connection line needs to be reserved on the mounting bracket. This redundant connection line will rotate with the mounting bracket, and the rotating mounting bracket may get tangled with this redundant connection line, which could lead to damage to the connection line or even detachment from the photovoltaic panel. Therefore, it is necessary to re-lay out the connection line access bracket to ensure that the connection line does not get tangled on the rotating photovoltaic panel mounting bracket. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable photovoltaic line access bracket to solve the problem that the reserved redundant connection wires may get tangled on the rotating photovoltaic panel mounting bracket.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Adjustable photovoltaic line access bracket, including:

[0007] The mounting tube has a connecting shell at its upper end. The connecting shell is hemispherical and has a direction adjustment component.

[0008] The line extension and retraction adjustment assembly includes a fixed rod connected inside the mounting tube. The mounting tube has a sliding groove arranged along its length. A sliding rod is slidably connected in the sliding groove. A counterweight is connected to the sliding rod. The photovoltaic connection wire passes through the mounting tube and the connecting shell, and winds around the fixed rod and the sliding rod.

[0009] Preferably, the direction adjustment component includes a spherical shell sleeved on the connecting shell, with openings at both the upper and lower ends of the spherical shell. A flap is connected to the upper end of the spherical shell, and an installation ring is fixedly connected to the installation tube. Multiple abutments are connected in a ring array on the installation ring, and abutment rings are fixedly connected to the upper ends of the multiple abutments. The abutment rings abut against the lower end of the spherical shell.

[0010] Preferably, the abutment is M-shaped and is made of spring steel.

[0011] Preferably, the counterweight is threaded onto the slide bar.

[0012] Preferably, the end of the counterweight abuts against the side wall of the mounting tube.

[0013] Preferably, the mounting tube is fitted with a C-shaped mounting clip, and is connected to the photovoltaic mounting frame via the mounting clip.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

The connecting wire can pass through the access bracket and connect to the photovoltaic panel.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1:

[0023] Please see Figures 1-4 As shown, the adjustable photovoltaic line access bracket includes:

[0024] Mounting tube 1, the upper end of which is connected to a connecting shell 2, the connecting shell 2 being hemispherical and having a direction adjustment component;

[0025] The line extension and retraction adjustment assembly includes a fixed rod 8 connected inside the mounting tube 1. The mounting tube 1 has a sliding groove 9 arranged along the length direction. A sliding rod 10 is slidably connected in the sliding groove 9. A counterweight 11 is connected to the sliding rod 10. The photovoltaic connecting wire 13 passes through the mounting tube 1 and the connecting shell 2, and winds around the fixed rod 8 and the sliding rod 10.

[0026] As can be seen from the above, an adjustable photovoltaic line access bracket is formed by setting up an installation pipe 1, a connecting shell 2, a direction adjustment component, and a line extension and retraction adjustment component. The connecting line 13 can pass through the access bracket and connect to the photovoltaic panel. When the photovoltaic panel rotates, the redundant connecting line 13 inside the installation pipe 1 will extend and retract to cooperate with the rotating photovoltaic panel. Since the redundant connecting line 13 always stays in the installation pipe 1, it will not get tangled on the rotating photovoltaic panel mounting bracket, effectively maintaining the safety of the connecting line 13 in use.

[0027] Please see Figures 3-4 As shown, the direction adjustment component includes a spherical shell 3 spherically fitted onto the connecting shell 2. The upper and lower ends of the spherical shell 3 are open, allowing the spherical shell 3 to rotate on the connecting shell 2. Due to the lower opening of the spherical shell 3, the spherical shell 3 can rotate at multiple angles on the connecting shell 2. A flap 4 is connected to the upper end of the spherical shell 3. The flap 4 flips outward, which can increase the curvature at the upper opening of the spherical shell 3 and prevent excessive friction when the connecting line 13 slides on the spherical shell 3, which could damage the outer sheath of the connecting line 13. An installation ring 7 is fixedly connected to the installation tube 1. Multiple abutment pieces 6 are connected in a ring array on the installation ring 7. The abutment pieces 6 are M-shaped and made of spring steel, possessing strong elasticity. Abutment ring 5 is fixedly connected to the upper end of the multiple abutment pieces 6, and the abutment ring 5 abuts against the lower end of the spherical shell 3.

[0028] As can be seen from the above, when the rotating photovoltaic panel drags the connecting line 13 to move out of the ball head shell 3, the connecting line 13 drives the sliding rod 10 and the counterweight 11 to slide along the slide groove 9, and the photovoltaic panel will cause the connecting line 13 to deviate at a certain angle. At this time, the connecting line 13 will press on the flip plate 4, and the flip plate 4 will apply pressure to the ball head shell 3. The ball head shell 3 under pressure tilts and presses the abutment 6 on this side, forcing the abutment 6 to bend. The tilted ball head shell 3 and the flip plate 4 can increase the bending arc of the connecting line 13 and avoid excessive friction between the connecting line 13 and the ball head shell 3. When the rotating photovoltaic panel no longer applies tension to the connecting line 13, causing the connecting line 13 to loosen, the weight of the counterweight 11 and the sliding rod 10 is transferred to the connecting line 13. At this time, the counterweight 11 and the sliding rod 10 sliding down along the slide groove 9 will drag the connecting line 13 downward, so that the redundant loose connecting line 13 outside the mounting tube 1 retracts into the mounting tube 1.

[0029] Please see Figure 4 As shown, the counterweight 11 is threaded onto the slide rod 10. Users can install counterweights 11 of different weights onto the slide rod 10 according to installation requirements, thereby applying different amounts of tension to the connecting wire 13, so that connecting wires 13 of different specifications can be folded and stored in the installation tube 1.

[0030] The end of the counterweight 11 abuts against the side wall of the mounting tube 1 to prevent the slide rod 10 from tilting when sliding in the slide groove 9, and to ensure that the slide rod 10 can stably apply tension to the connecting line 13.

[0031] The mounting tube 1 is fitted with a C-shaped mounting clip 12, and is connected to the photovoltaic mounting frame through the mounting clip 12.
