Description

Technical Field

[0001] The utility model relates to the technical field of brackets, and in particular to a photovoltaic bracket. Background Art

[0002] Most existing photovoltaic module brackets are fixed on the ground or roof. The bracket is made into a rectangular frame. The upper frame is connected to the bottom legs through an intermediate support structure. The connection method between the legs and the ground or roof is mainly welding and bolting.

[0003] The existing bracket has the following technical problems during installation:

[0004] When installing photovoltaic modules, several existing photovoltaic brackets are generally set along the length of the photovoltaic panel. Multiple photovoltaic brackets support the photovoltaic panel above at the same time. In order to ensure that the photovoltaic panel does not tilt after installation, it is necessary to measure the marking line in advance before installation to ensure that the installation point of each photovoltaic bracket is on a straight line, which reduces the installation efficiency. Utility Model Content

DETAILED DESCRIPTION

[0021] The specific implementation of this embodiment is described below with reference to the accompanying drawings.

[0022] Reference Figure 1 A photovoltaic bracket includes support beams 9 arranged in pairs, one end of the support beam 9 is hinged to the first base plate 1 through a connecting rod 3, and the other end of the support beam 9 is hinged to the second base plate 2. A slide groove 5 is provided on the support beam 9 along the length direction, and scissors forks 4 are cross-arranged between the support beams 9. The scissors forks 4 are movably arranged in the slide groove 5 through a sliding rod. The rotation of the scissors forks 4 can drive the contraction or expansion of the support beams 9. While the scissors forks 4 rotate, the sliding rods of the scissors forks 4 are restricted in the slide groove 5, ensuring that the ends of the support beams 9 are in a straight line after the spacing of the support beams 9 is adjusted.

[0023] The scissors fork 4 includes a first scissors rod 41 and a second scissors rod 42 arranged crosswise, and the first scissors rod 41 and the second scissors rod 42 are rotatably connected along the central axis of the pin shaft 10. The first scissors rod 41 and the second scissors rod 42 have pin holes centrally provided, and the pin shaft 10 is arranged in the pin holes. The first scissors rod 41 and the second scissors rod 42 form the scissors fork 4. The rotation of the scissors fork 4 can drive the contraction or expansion of the support beam 9. Under the limit of the scissors fork 4, the ends of the support beam 9 are ensured to be in a straight line after the spacing of the support beam 9 is adjusted, thereby ensuring that the photovoltaic panel will not be skewed after installation.

[0024] One end of the first scissor rod 41 is rotatably installed on the support beam 9 through a fixed bolt rod, and the other end of the first scissor rod 41 is slidably set on the slide groove 5 through a sliding rod. One end of the second scissor rod 42 is rotatably installed on the support beam 9 through a fixed bolt rod, and the other end of the second scissor rod 42 is slidably set on the slide groove 5 through a sliding rod. The sliding rod and the bolt rod are both studs, and the slide groove 5 and the bolt rod surface are provided with threads. The sliding rod and the bolt rod can be fixed by nuts after passing through the side wall of the support beam 9. When adjusting, the nuts are loosened. At this time, the bolt rod is fixed in the corresponding screw hole of the support beam 9. One end of the first scissor rod 41 and the second scissor rod 42 can rotate around the bolt rod, and the sliding rod is restricted in the slide groove 5. The other end of the first scissor rod 41 and the second scissor rod 42 can translate along the slide groove 5.

[0025] The slide 5 is opened on the upper side of the support beam 9. Since only one end of the first scissor rod 41 and the second scissor rod 42 needs to move, and the solar panel requires an angle when installing, the slide 5 is opened on the upper side of the support beam 9, so that the sliding rod can slide downward more smoothly along the slide 5 under the action of gravity, and is arranged close to the second base plate 2. A semicircular hole is set at the end of the slide 5. The diameter of the semicircular hole is larger than the diameter of the sliding rod. The spacing between the slides 5 is larger than the diameter of the sliding rod, thereby ensuring the smoothness of the sliding of the sliding rod.

[0026] One end of the connecting rod 3 is hinged to the support beam 9 by bolts, and the lower end of the connecting rod 3 is installed on the counterweight block 8 through the first base plate 1, and the lower end of the support beam 9 is installed on the counterweight block 8 through the second base plate 2. The first base plate 1 is a U-shaped plate, and the side wall of the first base plate 1 is hinged to the connecting rod 3 by bolts. The second base plate 2 is a U-shaped plate, and the side wall of the second base plate 2 is hinged to the connecting rod 3 by bolts. The end of the connecting rod 3 is provided with a rotation space when the angle of the support beam 9 is adjusted. The first base plate 1 and the second base plate 2 are set as U-shaped plates, and the spacing between the U-shaped plates also provides a rotation space when the angle of the support beam 9 and the connecting rod 3 is adjusted.

[0027] The photovoltaic bracket installation process is as follows:

[0028] Adjust the spacing of the support beams 9 according to the size of the photovoltaic panels. The adjustment process is to loosen the sliding screw 6, and then push and pull the support beam 9. At this time, the sliding screw 6 at the end of the first scissor rod 41 and the second scissor rod 42 slides along the slide groove 5, and the first scissor rod 41 and the second scissor rod 42 rotate along the pin 10. After the size adjustment is completed, screw the nuts on the corresponding sliding screw 6 and the fixed screw 7 to fix the first scissor rod 41 and the second scissor rod 42. At this time, the spacing of the support beams 9 is fixed, and then the support beams 9 are fixed to the connecting rod 3 with bolts. After adjusting the angle of the connecting rod 3, the connecting rod 3 is fixed to the second base plate 2 by bolts, and the end of the support beam 9 is fixed to the first base plate 1 by bolts. Then the second base plate 2 and the first base plate 1 are fixed to the center of the counterweight block 8 by bolts. The solar panels can be installed on the side walls of the fixed support beam 9 through the existing metal keel structure and bolts.

[0029] Although the above description of the specific implementation methods of the present invention is combined with the accompanying drawings, it does not limit the scope of protection of the present invention. Technical personnel in the relevant field should understand that on the basis of the technical solution of the present invention, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the present invention.
