Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic supports, in particular to a solar photovoltaic module mounting support and mounting method. BACKGROUND

[0002] Photovoltaic is the abbreviation of solar power generation system, which is a power generation system that converts solar radiation into electric energy through the photovoltaic effect of solar cell semiconductor materials. When laying photovoltaic panels, photovoltaic supports are needed.

[0003] The photovoltaic support generally includes vertical columns, and inclined beams and cross beams arranged on the vertical columns. The inclined beams are parallel to each other, and the cross beams are parallel to each other. The inclined beams and the cross beams are arranged in a crisscross manner to form a square mounting area, and the photovoltaic is mounted in the area.

[0004] During installation, the two ends of the inclined beam are respectively connected to two vertical columns, and then the cross beam is sequentially mounted on two parallel inclined beams. The cross beam is fixed to the inclined beam by bolts or other means. The two ends of the cross beam are respectively connected to two inclined beams. When installing the cross beam, the operator can easily tilt the other end under the action of its own gravity when fixing one end of the cross beam, thereby causing poor levelness of the cross beam after installation. SUMMARY

[0005] In order to improve the levelness of the cross beam during installation, the present application provides a solar photovoltaic module mounting support and mounting method.

[0006] The solar photovoltaic module mounting support provided by the present application adopts the following technical scheme:

[0007] A solar photovoltaic module mounting support includes inclined beams and cross beams. The inclined beams and the cross beams are both provided with mounting slots in the same direction as their length. The upper ends of the inclined beams and the cross beams are provided with communication slots connected to the mounting slots. The width of the communication slots is smaller than the width of the mounting slots. The two ends of the cross beam are provided with communication holes penetrating the cross beam. The communication holes are rotatably connected to connecting rods. The lower ends of the connecting rods are fixed to fixed blocks below the cross beam. The length of the fixed blocks is the same as the width of the mounting slots, and the width of the fixed blocks is smaller than the width of the communication slots. The upper ends of the connecting rods are provided with indicating blocks in the cross beam. The direction of the indicating blocks is parallel to the direction of the fixed blocks.

[0008] By adopting the technical scheme, when the cross beam and the inclined beam are fixedly installed, the fixed block is rotated to be parallel to the communication groove, so as to insert the fixed block from the communication groove on the inclined beam into the installation groove of the inclined beam. At this time, the connecting rod is rotated, so that the two ends of the fixed block are in contact with the inner walls of the installation groove of the inclined beam, and the connecting rod cannot continue to rotate. When the connecting rod is rotated, the indicating block is synchronously rotated until the fixed block is moved to the position, and the fixed rod and the connecting rod cannot be rotated. At this time, the positional relationship between the indicating block and the cross beam is observed. If the indicating block and the cross beam are parallel to each other, it is indicated that the cross beam and the inclined beam are perpendicular to each other and are in a horizontal state, and the levelness of the cross beam is good. If the cross beam and the indicating block are not parallel, the operator can rotate the cross beam to adjust the cross beam, so that the cross beam is parallel to the indicating block, thereby ensuring the levelness of the cross beam.

The operator rotates the cross beam to adjust the position of the cross beam until the indicating block is directly pressed into the indicating groove under the action of the indicating spring, the adjustment is completed, and the levelness of the cross beam is ensured. The indicating spring provides pressure to the indicating block, so as to facilitate the embedding of the indicating block in the indicating groove, the operator does not need to additionally slide the indicating block, the indicating block always provides a downward pressure to the cross beam to press the cross beam on the inclined beam, and the connection strength between the cross beam and the inclined beam is increased.

The fixed plate and the fixed slot ensure the position accuracy of the rotation of the fixed block, ensure the perpendicularity of the fixed block and the inclined beam, and thus ensure the levelness of the cross beam. Moreover, the fixed plate always provides upward pressure on the inclined beam under the action of the fixed spring, and the inclined beam is pressed tightly on the cross beam, thereby increasing the connecting strength of the cross beam and the inclined beam.

The upper end of the inclined beam 1 and the cross beam 2 is provided with a communication groove 4 in communication with the installation groove 3, the width of the communication groove is smaller than the width of the installation groove 3, and the connecting piece is installed in the installation groove 3 through the communication groove 4, thereby facilitating installation.

[0041] Referring to Figs. 1-2 , the two ends of the cross beam 2 are provided with a communication hole 21 penetrating through the cross beam 2, and the bottom of the inner wall of the cross beam 2 is provided with an indicating groove 22 arranged along the length direction of the cross beam 2, and the communication hole 21 is arranged in the middle of the indicating groove 22. The upper end of the inner wall of the inclined beam 1 is provided with a plurality of fixing grooves 11 perpendicular to the length direction of the inclined beam 1, and the fixing grooves 11 are uniformly distributed along the length direction of the inclined beam 1. The connecting piece is inserted into the installation groove 3 of the inclined beam 1 from the cross beam 2 through the communication hole 21 and connected with the fixing groove 11, thereby fixing and connecting the cross beam 2 with the inclined beam 1. The fixing groove 11 limits the installation position of the cross beam 2.

[0042] Referring to Figs. 1-2 , the connecting piece comprises a connecting rod 5, the connecting rod 5 is rotationally connected in the communication hole 21, and the upper end of the connecting rod 5 is located in the installation groove 3 of the cross beam 2, and the lower end of the connecting rod 5 penetrates out of the communication hole 21 and is fixed below the cross beam 2 with a fixing block 51 used for being connected with the inclined beam 1. The length of the fixing block 51 is the same as the width of the installation groove 3, the width of the fixing block 51 is smaller than the width of the communication groove 4, and the two ends of the fixing block 51 are arc-shaped. The operator can rotate the connecting rod 5, so that the fixing block 51 is consistent with the direction of the communication groove 4 on the inclined beam 1, thereby facilitating the insertion of the fixing block 51 into the installation groove 3 of the inclined beam 1 from the communication groove on the inclined beam 1, and then rotating the connecting rod 5, so that the fixing block 51 is perpendicular to the inside of the inclined beam 1, and the fixing block 51 is in contact with the two sides of the inner wall of the installation groove 3 in the inclined beam 1, thereby realizing the fixed installation of the fixing block 51 and the inclined beam 1.

[0043] Referring toFigs. 1-2 The lower end of the connecting rod 5 is vertically slidably connected with a fixing sheet 55 above the fixing block 51, and a plurality of fixing springs 56 are arranged between the fixing sheet 55 and the fixing block 51. When the fixing sheet 55 is located in the installation groove 3 of the inclined beam 1, the fixing sheet 55 always abuts against the top of the inner wall of the installation groove 3 of the inclined beam 1 under the action of the fixing springs 56. The shape of the fixing sheet 55 is the same as that of the fixing block 51 and the direction is consistent. That is, the fixing sheet 55 can also be inserted into the installation groove 3 of the inclined beam 1 through the communication groove 4 of the inclined beam 1.

[0044] With reference to Figs. 1-2 When the fixing block 51 is embedded in the installation groove 3 of the inclined beam 1 and the fixing sheet 55 is pressed into the installation groove 3 of the inclined beam 1 during installation, the position of the fixing sheet 55 is opposite to the fixing groove 11 but the direction is perpendicular to each other.

[0046] With reference to Figs. 1-2The upper end of the connecting rod 5 is square-shaped, and an indicating piece 53 is fixed to the outer wall of the upper end of the connecting rod 5. An indicating block 52 vertically slidingly connected to the connecting rod 5 is connected to the lower end of the indicating piece 53 through an indicating spring 54. The direction of the indicating block 52 is parallel to the direction of the fixed block 51. The shape of the indicating block 52 is consistent with the shape of the indicating groove 22, and the length of the indicating block 52 is less than the length of the indicating groove 22. The lower end of the indicating block 52 is always in contact with the cross beam 2 under the elastic force of the indicating spring 54. The operator rotates the connecting rod 5 to drive the indicating block 52 to rotate synchronously. When the fixed piece 55 is embedded in the fixed groove 11, the connecting rod 5 is fixedly connected with the inclined beam 1 and the cross beam 2. The direction of the indicating block 52 is parallel to the direction of the fixed block 51, and the direction of the indicating block 52 is perpendicular to the inclined beam 1. At this time, if the indicating block 52 is embedded in the indicating groove 22 under the action of the indicating spring 54, it indicates that the cross beam 2 is also perpendicular to the inclined beam 1 and is in a horizontal state. If the indicating block 52 is not embedded in the indicating groove 22, the operator rotates the cross beam 2 to make the direction of the indicating groove 22 consistent with the direction of the indicating block 52, so that the indicating block 52 is embedded in the indicating groove 22, thereby ensuring the levelness of the cross beam 2.

An adjusting rod 58 is arranged in the adjusting hole 57. A semicircular connecting groove 59 is formed in the outer wall of the connecting rod 5 and located in the communication hole 21. The connecting groove 59 is in communication with the adjusting hole 57. The rotating angle range of the connecting rod 5 is about 0-90°, and the semicircular connecting groove 59 with 180° satisfies the rotating requirement of the connecting rod 5. The outer wall of the adjusting rod 58 is fixedly connected with a telescopic rod 581 slidingly connected in the connecting groove 59. The end of the telescopic rod 581 away from the adjusting rod 58 penetrates out of the connecting groove 59 and is fixedly connected with the inner wall of the communication hole 21. An adjusting knob 582 is arranged at the upper end of the adjusting rod 58. The operator can rotate the adjusting rod 58 to drive the cross beam 2 to rotate, thereby finely adjusting the position of the cross beam 2.

[0049] The implementation principle of the solar photovoltaic module mounting support according to the embodiment of the application is as follows: an operator vertically fixes the stand 7 and obliquely fixes the inclined beam 1 on the stand 7. The operator rotates the connecting rod 5 so that the direction of the fixing block 51 is consistent with the direction of the communication groove 4 on the inclined beam 1, inserts the fixing block 51 into the mounting groove 3 of the inclined beam 1 through the communication groove 4 of the inclined beam 1, and continues to insert the fixing block 51 into the mounting groove 3 of the inclined beam 1 until the fixing piece 55 is also located in the mounting groove 3 of the inclined beam 1. The operator rotates the connecting rod 5 and presses the fixing piece 55 into the fixing groove 11 of the inclined beam 1 so that the fixing piece 55 abuts against the top of the inner wall of the mounting groove 3 of the inclined beam 1. At this time, if the indicating block 52 is embedded in the indicating groove 22 under the action of the indicating spring 54, it indicates that the cross beam 2 is in a horizontal state and the installation is completed; if the indicating block 52 is not embedded in the indicating groove 22, the operator rotates the cross beam 2 so that the direction of the indicating groove 22 is consistent with the direction of the indicating block 52, and the indicating block 52 is embedded in the indicating groove 22, thereby completing the installation.
