Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

Referring to Figures 1-9, a modular quick-installation photovoltaic bracket in this embodiment includes two modules, one is the main frame 1, and the other is the photovoltaic module used to connect the photovoltaic panel 2 and the main frame 1. Plate connection structure 3, the main frame 1 includes a support frame 10 and a transverse cylinder 12 detachably connected to the support frame 10. Specifically, the support frame 10 includes a connecting barrel 11 and two supports 102 fixed on the sides of the connecting barrel 11. and a mounting plate 103 fixed on the lower end of the support member 102. The mounting plate 103 is provided with a plurality of mounting holes 1031. In this embodiment, the support member 102 has a tubular structure, and the two support members 102 are distributed front and back on the lower side of the connecting tube 11. For stable support, in this embodiment, the angle between the two connecting tubes 11 is Set to 60 degrees. In order to achieve a detachable connection between the support frame 10 and the horizontal cylinder 12, in this embodiment, the connecting tube 11 has several inserts 111 on the side, the horizontal cylinder 12 is sleeved on the outside of the connecting tube 11, and the two sides of the horizontal cylinder 12 The end is provided with slots 122 corresponding to a plurality of slots 111 one-to-one. When the horizontal cylinder 12 is connected to the support frame 10, the horizontal cylinder 12 is placed outside one end of the connecting tube 11, so that the horizontal cylinder 12 and the connecting tube 11 are connected. After that, the connecting tube 11 can be connected to the horizontal cylinder 12. The other end of 11 is inserted into the connecting tube 11 of another support frame 10. When the positions of the two support frames 10 are fixed, the horizontal cylinder 12 facilitates the fixed connection of the support frames 10. When disassembling, remove one of the two ends of the horizontal cylinder 12. After the position of the support frame 10 is unfixed, the support frame 10 with the unfixed position can be pulled out from the transverse cylinder 12. Correspondingly, the other end of the transverse cylinder 12 can be removed from the other support frame 10. It is worth mentioning that when the connecting tube 11 is plugged into the horizontal cylinder 12, each insert 111 needs to be plugged into each insert slot 122 respectively. The plug-in cooperation between the two can limit the position of the horizontal cylinder 12 relative to the connecting tube 11 Turn.

In this embodiment, the horizontal cylinder 12 is provided with five sets of strip-shaped mounting holes 121 that penetrate the opposite sides of the transverse cylinder 12 at intervals along its length direction. The length direction of the strip-shaped mounting holes 121 is consistent with the length direction of the transverse cylinder 12 . The parallel, specific, strip-shaped mounting holes 121 are rectangular in shape, and the four corners are rounded. In this embodiment, the photovoltaic panel connection structure 3 includes a connecting shell 31, a connecting piece 32 connected to the connecting shell 31, and a first elastic member 33 connected between the connecting piece 32 and the connecting shell 31. In this embodiment, the third An elastic member 33 is a coil spring.

In this embodiment, the connecting shell 31 is provided with a round rod chute that runs up and down. The connecting shell 31 is provided with arc-shaped plates 37 on both front and rear sides that can cover the outside of the horizontal cylinder 12. The connecting piece 33 includes a circular rod and a chute. The rod chute is longitudinally slidably assembled with a round rod 331, a connecting portion 332 provided at the upper end of the round rod 331 for connecting the photovoltaic panel 2, and a connecting portion 332 fixed at the lower end of the round rod 331 and capable of extending downwards from the lower end of the connecting shell 31 and penetrating the bar. The bar-shaped plug connector 333 of the mounting hole 121 is in an arc shape that can cover the outside of the horizontal cylinder 12. The first elastic member 33 is provided between the connecting portion 332 and the connecting shell 31. And it is sleeved on the outside of the round rod 331. In this embodiment, in order to realize the connection between the connecting part 332 and the photovoltaic panel 2, a plurality of bolt insertion holes can be opened on the connecting part 332, and threads corresponding to the bolt insertion holes can be provided on one end of the photovoltaic panel 2. hole, so that the bolts can be inserted into the bolt insertion holes and tightened into the threaded holes, so that the connection part 332 and the photovoltaic panel 2 are fixed.

When the photovoltaic panel connection structure 3 is not installed on the main frame 1, its first elastic member 33 will push the connection shell 31 and the connection portion 332 to both sides respectively under its own elastic force. When the openings at the lower ends of the shells 31 are aligned, that is, when their length directions are parallel, the strip connector 333 will be retracted into the connection shell 31 and abut against the inner top wall of the connection shell 31 .

The installation method of the above photovoltaic bracket is as follows:

S1, fix the support frame 10 to the installation site. The installation site can be the top of the building or other ground. The fixing method can be to make the two installation plates 103 contact the ground, and then insert bolts into the installation plates 103 and tighten them with the ground to complete. After the support frame 10 is fixed, the horizontal cylinder 12 and the support frame 10 are installed. Specifically, the horizontal cylinder 12 is sleeved on the outside of one end of the connecting cylinder 11, and then another end of the horizontal cylinder 12 is inserted. After the connection tube 11 of a support frame 10 is plugged in, the support frame 10 is fixed to the ground, thereby completing the fixing operation of the main frame 1 and the ground. Both ends of the connecting cylinder 11 can be plugged into the horizontal cylinder 12, so the aforementioned fixing steps can be repeated to continue plugging in another horizontal cylinder 12 on the rear side of the support frame 10, and continue to plug on another horizontal cylinder 12 on the back side. The main frame 1 can be expanded by alternately repeating the supporting frame 10 and the supporting frame 10 .

S2, secure the connecting portion 332 of the connecting piece 32 to the photovoltaic panel 2. Specifically, fit the connecting portion 332 to one end of the threaded hole provided on the photovoltaic panel 2, and align each threaded hole with each bolt insertion hole, and then Insert the bolts into the bolt insertion holes and tighten them in the threaded holes, so that the connection portion 332 of the photovoltaic panel connection structure 3 and the photovoltaic panel 2 are fixed.

S3, attach the arc plate 37 to the outside of the horizontal cylinder 12, and align the strip connector 333 with one of the set of strip mounting holes 121, and then overcome the first elastic member 33 The elastic force presses down the connector 32 to insert the bar-shaped plug connector 333 into the bar-shaped mounting hole 121. After the bar-shaped plug connector 333 completely passes through the bar-shaped mounting hole 121, rotate it 90 degrees to insert the bar-shaped plug connector 333 into the bar-shaped mounting hole 121. The connector 333 is staggered with the strip-shaped mounting hole 121. In this state, the arc axis of the strip-shaped plug connector 333 will be parallel to the axis of the horizontal cylinder 12. Then the connector 32 is released to allow the first elastic member 33 to rebound and fit. The strip connector 333 and the arc plate 37 are clamped on the outside of the horizontal cylinder 12, so that the photovoltaic panel 2 is fixed to the main frame 1 through the photovoltaic panel connection structure 3.

It should also be noted that after the strip connector 333 is attached to the horizontal cylinder 12, since the first elastic member 33 is in a strong compression state at this time, the strip connector 333 is covered in an arc shape. Because it is outside the horizontal cylinder 12 , the strip connector 333 is difficult to rotate relative to the horizontal cylinder 12 , so the photovoltaic panel connecting structure 3 can maintain a relatively stable connection state with the connecting cylinder 11 .

Since the horizontal cylinder 12 has multiple sets of strip-shaped mounting holes 121, multiple photovoltaic panel connection structures 3 can be installed on the horizontal cylinder 12, that is, multiple photovoltaic panels 2 can be installed. As shown in this embodiment, one can Five photovoltaic panels 2 are installed on the horizontal cylinder 12.

It is worth mentioning that in the above-mentioned step S3, when the arc plate 37 is attached to the outside of the horizontal cylinder 12, the position of the arc plate 37 can be roughly aligned with the bar-shaped mounting hole 121 of the target group. Specifically, the bar The lower end of the shaped plug connector 333 is located between the length range of the strip mounting hole 121. Then the photovoltaic panel 2 can be pushed downward, so that the photovoltaic panel 2 pushes the connecting piece 32 to move downward relative to the connection shell 31. After the strip is plugged in, When the connector 333 extends downward from the connection shell 31, there will be two states. One is that the strip connector 333 is completely aligned with the target strip mounting hole 121 in the width direction, and the other is that the strip connector 333 is aligned with the target strip mounting hole 121. The strip-shaped mounting holes 121 are not completely aligned in the width direction. The following is a detailed introduction to the two states.

In the first state, the lower end of the bar-shaped connector 333 will be directly inserted into the bar-shaped mounting hole 121. Since the bar-shaped connector 333 is in the shape of an arc with a lower middle and higher sides, its lower end will be inserted into the bar-shaped mounting hole 121. After 121, if the bar-shaped mounting hole 121 is completely aligned with the bar-shaped mounting hole 121 in the length direction, the bar-shaped plug connector 333 will be directly inserted into the bar-shaped mounting hole 121. If the bar-shaped plug connector 333 is aligned in the length direction, If it is not completely aligned with the bar-shaped mounting hole 121, then when the bar-shaped plug connector 333 is inserted downward, its lower side will come into contact with one of the edges in the width direction of the bar-shaped mounting hole 121, and the bar-shaped plug connector 333 will not be completely aligned with the bar-shaped mounting hole 121. The arc bottom surface of the member 333 has a guiding function. Therefore, when the strip connector 333 moves downward, it will force the strip connector 333 to move toward the middle of the strip mounting hole 121 until the two are completely aligned. Therefore, even if the strip connector 333 moves downward, The shaped plug connector 333 is not completely aligned with the bar-shaped mounting hole 121 in the length direction, and can be smoothly inserted into the bar-shaped mounting hole 121 during the continuous downward movement.

In the second state, the lower end of the strip connector 333 will abut against the outside of the horizontal cylinder 12. In this state, the connector 32 can be pushed downward while rotating the connector 32 around the horizontal cylinder 12. This process , the lower end of the strip connector 333 will pass through the strip mounting hole 121, that is, the strip connector 333 can be rotated to be completely aligned with the strip mounting hole 121 in the width direction, because the strip connector 333 remains Therefore, after the strip connector 333 and the strip mounting hole 121 are completely aligned in the width direction, the lower end of the strip connector 333 will be directly inserted into the strip mounting hole 121, and the subsequent movement process is the same as The movement process in the first state is the same and will not be repeated here. It can be seen that even if the strip connector 333 and the target strip mounting hole 121 are not completely aligned in the width direction, the user can easily achieve alignment and insertion by rotating the photovoltaic panel connection structure 3 .

When it is necessary to remove the photovoltaic panel 2 for maintenance, the corresponding photovoltaic panel 2 can be pushed downward relative to the connecting shell 31 so that the connecting piece 32 slides downward relative to the connecting shell 31. Of course, the corresponding connecting piece can also be directly removed. 32 is pushed downward relative to the connecting shell 31. After the uppermost end of the strip connector 333 is separated from the strip mounting hole 121, the connector 32 can be rotated 90 degrees to make the strip connector 333 and the strip mounting hole 121. 121 are completely aligned. At this time, the strip connector 333 can exit the strip mounting hole 121, so that the photovoltaic panel 2 can be removed from the main frame 1. The entire disassembly operation is simple and convenient, and does not require the use of tools, which is conducive to Performing separate maintenance on photovoltaic panels 2 can improve maintenance efficiency to a certain extent.

In order to fix the photovoltaic panel 2 at different tilt angles, in this embodiment, each group of bar-shaped mounting holes 121 has four bar-shaped mounting holes 121 , and the four bar-shaped mounting holes 121 of each group of bar-shaped mounting holes 121 are arranged around The circumferential surface of the cylinder 12 is evenly distributed, so that the strip-shaped connector 333 can be inserted into the strip-shaped mounting holes 121 with different angles as needed to fix the photovoltaic panel 2 at different angles. It is worth mentioning that the strip connector 333 can be inserted from either end of the strip mounting hole 121. Therefore, each set of strip mounting holes 121 can provide 8 installation angles to choose from, which can meet a variety of tilts. Installation requirements.

In order to stabilize the connection between the photovoltaic panel connection structure 3 and the main frame 1, this embodiment also makes the following settings for the photovoltaic panel connection structure 3. Specifically, the photovoltaic panel connection structure 3 also includes a longitudinal sliding assembly on the inside of the connection shell 31 and The cylindrical plug connector 34 that can be inserted into the bar-shaped mounting hole 121 and has a shape that matches the bar-shaped mounting hole 121, and the second elastic member 35 fixed between the connecting shell 31 and the cylindrical plug connector 34. Both the cylindrical plug connector 333 and the round rod 12 can penetrate the cylindrical plug connector 34. In this embodiment, the second elastic member 35 is a rectangular coil spring. A combined chute 334 is provided on the side of the round rod 331. The combined chute 334 includes a first vertical groove 3341 that penetrates the lower end of the round rod 331 and is parallel to the axis of the round rod 331. It is connected to the upper end of the first vertical groove 3341 and along the circumferential surface of the round rod 331. The opened horizontal groove 3342 and the second vertical groove 3343 connected to the end of the horizontal groove 3342 away from the first vertical groove 3341 and extending upward along the axis of the round rod 331; on the normal plane of the axis of the round rod 331, the first vertical groove 3341 and The angle between the connection between the axes of the round rods 331 and the connection between the axis of the second vertical groove 3343 and the round rod 331 is 90 degrees; the cylindrical connector 34 is provided with a sliding assembly that is slidably assembled in the combined chute 334 36 , the distance between the upper end of the second vertical groove 3343 and the lower end of the round rod 331 minus the distance between the upper end of the sliding part 36 and the lower end of the cylindrical connector 34 is less than the distance between the upper and lower ends of the strip mounting hole 121 .

On the basis of the above structure, when the photovoltaic panel connection structure 3 is not installed on the main frame 1, its first elastic member 33 will push the connection shell 31 and the connection part 332 to both sides respectively under its own elastic force, so that the bar-shaped The plug connector 333 is retracted into the connection shell 31 and abuts against the inner top wall of the connection shell 31. In this state, the second elastic member 35 will drive the cylindrical plug connector 34 to be retracted into the connection shell 31 under its own elastic force. In the state, the sliding part 36 is in the first vertical groove 3341.

When installing the photovoltaic panel connection structure 3 and the horizontal cylinder 12, attach the arc plate 37 to the outside of the horizontal cylinder 12, and connect the strip connector 333 with one of the set of strip mounting holes 121. The mounting holes 121 are aligned, and then the connector 32 is pressed down against the elastic force of the first elastic member 33 to insert the bar-shaped connector 333 into the bar-shaped mounting hole 121. Before the bar-shaped connector 333 penetrates the bar-shaped mounting hole 121 , since the distance between the upper end of the second vertical groove 3343 and the lower end of the round rod 331 minus the distance between the upper end of the sliding part 36 and the lower end of the cylindrical connector 34 is smaller than the distance between the upper and lower ends of the strip mounting hole 121, therefore, The upper end of the first vertical groove 3341 (that is, the top wall) will contact the upper end of the sliding part 36, so the first vertical groove 3341 will cooperate with the sliding part 36 to overcome the elastic force of the second elastic member 35 and drive the cylindrical connector 34 downward together. displacement, after the bar-shaped plug connector 333 penetrates the bar-shaped mounting hole 121, the cylindrical plug connector 34 will be inserted into the bar-shaped mounting hole 121. In this state, the transverse groove 3342 will be aligned with the sliding part 36, and then the The connector 32 can be rotated 90 degrees toward the second vertical slot 3343. In this state, the arc axis of the strip connector 333 will be parallel to the axis of the horizontal cylinder 12, and the sliding portion 36 will be in contact with the second vertical slot. 3343 are aligned, since the second elastic member 35 continues to pull the cylindrical plug connector 34, the cylindrical plug connector 34 will be located upwards at one end distance relative to the round rod 331 until the sliding portion 36 abuts the second vertical groove 3343 At the upper end, the push force exerted on the connecting member 32 is then canceled, causing the first elastic member 33 to rebound and cooperate with the strip connector 333 and the arc plate 37 to be clamped on the outside of the horizontal cylinder 12, thus completing the installation.

During the above installation process, the cylindrical connector 34 will be automatically inserted into the bar-shaped installation hole 121. Since the sliding portion 36 on the cylindrical connector 34 will automatically snap into the second vertical groove 3343, the round rod 331 will The rotation will be restricted by the sliding part 36, and the sliding part 36 realizes longitudinal sliding assembly with the connecting shell 31 through the cylindrical plug connector 34. Therefore, the round rod 331 at this time will not be able to rotate relative to the connecting shell 31, and the bar-shaped plug The joint 333 is also restricted from rotating, thereby improving the connection stability between the photovoltaic panel connection structure 3 and the main frame 1 .

It is worth mentioning that the side of the cylindrical plug connector 34 is provided with a toggle member 341 that penetrates the connection shell 31. The side of the connection shell 31 is provided with a toggle groove 312 for the toggle member 341 to slide up and down. The toggle member 341 can move toward Slide out the toggle groove 312, so that when the photovoltaic panel 2 needs to be removed for maintenance, the toggle member 341 is first pushed to the side of the strip connector 333, so that it drives the sliding part 36 through the cylindrical connector 34 Exit the second vertical groove 3343, that is, slide into the horizontal groove 3342. After the sliding part 36 is located in the horizontal groove 3342, the round rod 331 can rotate relative to the connecting shell 31. At this time, it can be disassembled according to the aforementioned disassembly method. , which will not be described again here.

In order to facilitate the assembly of various parts of the photovoltaic panel connection structure 3, in this embodiment, the connection shell 31 is made up of two connection shell half shells 313. Among the two connection shell half shells 313, one of the connection shell half shells is The splicing surface of 313 is provided with a plurality of latch pins 3133, and the splicing surface of the other connecting shell half shell 313 is provided with a plurality of latch slots 3134 for insertion of the plurality of latch pins 3133. In this embodiment, the round rod chute is made up of two round rod chute half grooves 3111. The two round rod chute half grooves 3111 are respectively located on the two connecting shell half shells 313. In addition, the arc plate 37 The two arc-shaped half-plates 371 are spliced together. The two arc-shaped half-plates 371 are respectively located on the two connecting shell half-shells 313. Similarly, the toggle groove 312 is formed by splicing two toggle grooves and half-slots 3121. , the two toggle groove half grooves 3121 are respectively located on the two connecting shell half shells 313. The portion of the cylindrical plug connector 34 located in the two connecting shell half-shells 313 is provided with wedge-shaped slide blocks 343 arranged longitudinally, and the two connecting shell half-shells 313 are both provided with wedge-shaped slide grooves for the wedge-shaped slide blocks 343 to be inserted longitudinally. 3131.

During assembly, first assemble the first elastic member 33 on the outside of the round rod 331. When the first elastic member 33 naturally stretches, its pitch is greater than the diameter of the round rod 331, so it can directly pass between the circles of the first elastic member 33. Assemble the first elastic member 33 on the outside of the round rod 331 with a gap of When inserting, the first vertical groove 3341 needs to be aligned with the sliding part 36 so that the sliding part 36 can smoothly enter the first vertical groove 3341, and then the second elastic member 35 is fixed on the upper end of the cylindrical plug connector 34. In this implementation In the example, welding is used here to fix, and then the combination of the cylindrical plug connector 34, the second elastic member 35 and the connecting piece 32 is installed into one of the connecting shell half shells 313.
