Description

Technical Field

[0001] The present invention relates to the technical field of photovoltaic modules, and in particular to a side anchor and a flexible photovoltaic support system for side columns. Background Art

[0002] The flexible photovoltaic support mainly includes a front column (side column), a main cable, and a stay cable device. The side columns are arranged horizontally or vertically and directly support the weight of the photovoltaic modules as the core load-bearing structure of the support. The function of the stay cable is to offset the lateral thrust of the wind or snow load on the side column through the oblique tension, prevent the main cable from excessive deviation or distortion, form a triangular stable structure with the main cable (similar to the principle of a cable-stayed bridge), disperse the load and reduce the sag of the main cable.

[0003] As shown in the attached Figure 7 and the attached Figure 8 figures, the connection methods between the side column and the stay cable in the prior art are respectively shown. It can be clearly seen that the existing stay cable setting method is as follows: a pin hole is drilled through the upper end of the side column, and then a pin shaft is inserted into the pin hole and ensured that both ends of the pin shaft can protrude from the pin hole. Then, a swivel screw or a similar connecting piece is used to movably hinge with the two protruding parts on both sides of the pin shaft, and the other end of the connecting piece is fixed to the stay cable through a compression anchor. As shown in the attached Figure 9 figure, the end of the stay cable far from the connecting piece is usually connected to the tensile pile of the stay cable assembly by a U-bolt. By adjusting the U-bolt, the tension of the stay cable can be adjusted, thus completing the setting of the stay cable.

[0004] However, the above scheme has the following defects: the connection structure of the stay cable is too complex, the operation during installation is cumbersome, and during installation, it is often necessary to first fix the main cable to the pin shaft through a compression anchor, and then install the connecting piece for connecting the stay cable at both ends of the pin shaft, so that the stay cable can only be installed after the main cable is installed. There is a strict installation sequence limit between the two, resulting in problems of inconvenient installation and low installation efficiency. Summary of the Invention

[0005] In view of this, the purpose of the present invention is to provide a side anchor and a flexible photovoltaic support system for side columns to solve the technical problems of cumbersome operation and difficult installation of the stay cable in the existing flexible photovoltaic support.

[0009] Two inclined vertical plates are arranged on the side columns in an opposing manner, and the two inclined vertical plates are provided with grooves that cooperate with the pin shaft for rotation. Notches are formed on the inclined vertical plates for the pin shaft to be embedded in the grooves. The inner side walls of the two inclined vertical plates are spaced from each other to form a space for placing the limiting pad block, and the axial movement of the pin shaft is prevented by the mutual interference between the limiting pad block and the inclined vertical plate.

[0043] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments.

[0044] It should be noted that, unless otherwise defined, the technical terms or scientific terms used in the present invention should be understood by people with ordinary skills in the field to which the present invention belongs.

[0045] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, a side anchor and side column flexible photovoltaic support system comprises: a side column 1.6 and a pin shaft 10; a limiting pad 11 matched with the pin shaft 10, the limiting pad 11 and the pin shaft 10 are both provided with a through slot for one end of the inclined cable to pass through, the inner diameter of the through slot is smaller than the maximum outer diameter of the extrusion anchor provided at one end of the inclined cable, so as to prevent the end of the inclined cable with the extrusion anchor from passing through the through slot; two inclined upright plates 1.5 arranged on the side column 1.6 in an opposing manner, the two inclined upright plates 1.5 are provided with a slot 1.9 rotatably matched with the pin shaft 10, a notch is formed on the inclined upright plates 1.5 for the pin shaft 10 to be embedded in the slot 1.9, the inner side walls of the two inclined upright plates 1.5 are spaced from each other to form a space for placing the limiting pad 11, and the axial movement of the pin shaft 10 is prevented by the mutual interference between the limiting pad 11 and the inclined upright plates 1.5;

[0046] Adopting the above technical solution can improve the installation efficiency of stay cables. When in use, the stay cable is sequentially passed through the through grooves on the surfaces of the pin shaft 10 and the limit cushion block 11, and a section of the stay cable protrudes from the limit cushion block 11. Then, the extrusion anchor is installed on the part of the stay cable that protrudes from the limit cushion block 11. The pin shaft 10 at the upper end of the stay cable is clamped into the card slot 1.9 through the notch on the surface of the stay cable vertical plate 1.5, and it is ensured that the limit cushion block 11 is between the two stay cable vertical plates 1.5, that is, the two ends of the limit cushion block 11 are respectively in contact with the inner side walls of the stay cable vertical plates 1.5, preventing the stay cable vertical plates 1.5 from moving along the axis direction of the pin shaft 10. Since the limit cushion block 11 and the pin shaft 10 are fixed, the pin shaft 10 can be prevented from moving along its axis direction. The lower part of the stay cable is fixedly connected and tensioned with the stay cable component tensile pile through the U-shaped fastening device 7 and the side anchor base welding part 8 described in the following text. The installation efficiency is relatively high. In addition, the connection between the side column 1.6 and the stay cable can also adopt a rolling structure such as a bearing to replace it, including but not limited to the pin shaft 10;

[0047] In summary, the present invention can directly place the pin shaft 10 connecting the stay cable into the card slot 1.9 by using the notch through setting a pair of stay cable vertical plates 1.5 on the side column 1.6, opening a card slot 1.9 on the surface of the stay cable vertical plates 1.5, and forming a notch communicating with the card slot 1.9 on the surface of the stay cable vertical plates 1.5, so that the pin shaft 10 is connected to the stay cable vertical plates 1.5 in a hinged manner. And by setting a limit cushion block 11 on the surface of the pin shaft 10, the two ends of the limit cushion block 11 can be limited by the inner side walls between the stay cable vertical plates 1.5, thereby preventing the axial movement of the pin shaft 10, making the connection between the pin shaft 10 and the side column 1.6 not only stable but also convenient to install.

[0048] As Figure 5 shown, in this embodiment, the support system further includes a stay cable rib plate 1.4 with one end fixedly connected to the stay cable vertical plate 1.5, and the other end of the stay cable rib plate 1.4 is fixedly connected to the side column 1.6;

[0049] Adopting the above technical solution can improve the connection strength of the stay cable vertical plate 1.5. By setting a stay cable rib plate 1.4 between the stay cable vertical plate 1.5 and the side column 1.6, it can help prevent the stay cable from falling off due to damage to the welding joint between the stay cable vertical plate 1.5 and the side column 1.6.

[0050] As Figure 1 shown, in this embodiment, the support system further includes: a U-shaped fastening device 7 fixedly connected to the other end of the stay cable; a stay cable component tensile pile; a side anchor base welding part 8 for installing the U-shaped fastening device 7 on the stay cable component tensile pile;

[0051] As Figure 2As shown, in this embodiment, the U-shaped fastening device 7 includes a U-bolt 16 and a nut adapted thereto, and a cable connection base plate 12. The cable connection base plate 12 is provided with a jack for inserting the bolt end of the U-bolt 16.

[0052] As Figure 2 and Figure 3 As shown, in this embodiment, the side anchor base weldment 8 includes: a base plate 15 fixedly connected to the top end of the anti-pull pile of the stay cable assembly; two base stiffeners 14 disposed on the upper end of the base plate 15 in an opposing manner. There is a gap between the inner side walls of the two base stiffeners 14 to form a limit for the U-bolt 16 of the U-shaped fastening device 7. The surface of the base stiffener 14 is provided with a welding notch; an arc support plate 13 having two ends respectively connected to the welding notch. The outer diameter of the arc support plate 13 is adapted to the inner diameter of the U-bolt 16 of the U-shaped fastening device 7. The arc support plate 13 is a sleeve structure lacking a part of the circumference, so that the arc support plate 13 is fully welded to the base stiffener 14.

[0053] Adopting the above technical solution can fix the lower part of the stay cable to the anti-pull pile of the stay cable assembly. After the pin 10 at the upper part of the stay cable device 6 is pre-placed in the card slot 1.9 of the stay vertical plate 1.5, the lower part of the stay cable is passed through the hole on the surface of the cable connection base plate 12 and extends out for a certain length. An extrusion anchor is installed on the extended part of the stay cable. The U-bolt 16 is passed between the base stiffeners 14 and the U-bolt 16 is connected to the arc support plate 13. Then, the jack on the surface of the cable connection base plate 12 is aligned with the U-bolt 16 and inserted, ensuring that the threaded end of the U-bolt 16 protrudes from the cable connection base plate 12 for a certain length. The nut is initially installed on the protruding part of the U-bolt 16. By tightening the nut, the cable connection base plate 12 pulls the stay cable, causing the stay cable to generate tension. Since the arc support plate 13 is made of a circular tube with about three-quarters of the radian, the notch design of the arc support plate 13 facilitates its full welding with the base stiffener 14, making the connection between the arc support plate 13 and the base stiffener 14 more reliable.

[0054] As Figure 1 、 Figure 4 and Figure 5 As shown, in this embodiment, the bracket system further includes: an inter-column ear plate 1.3 provided with a first mounting hole, and the inter-column ear plate 1.3 is disposed on the surface of the side column 1.6; an inter-column support having second mounting holes respectively at both ends; a mounting member for penetrating and fixing the first mounting hole and the second mounting hole; there are two inter-column supports between adjacent side columns 1.6, namely the inter-column support A4 and the inter-column support B5. The inter-column support A4 and the inter-column support B5 and the side column 1.6 form a triangular bracket structure.

[0055] Adopting the above technical solution can further improve the connection stability of the side column 1.6. The first mounting holes on the surface of the inter-column ear plate 1.3 are kidney-shaped holes, which have a certain distance adjustment function and can conveniently adjust the positions of the inter-column supports A4 and B5 to adapt to different spacing requirements.

[0056] As Figure 2 , Figure 3 and Figure 5 shown, in this embodiment, the support system further includes: a column top ring 1.1 fixedly provided at the top of the side column 1.6. The column top ring 1.1 is provided with a plurality of circular ring holes 1.1.1 arranged in a circular pattern on its outer circumference with its axis as the center. The column top ring 1.1 is provided with an arc-shaped through groove on the other side circumference relative to the circular ring holes 1.1.1. The circular ring holes 1.1.1 and the arc-shaped through groove are used for the main cable 3 to pass through. The inner diameter of the circular ring holes 1.1.1 is smaller than the maximum outer diameter of the extrusion anchor at one end of the main cable 3.

[0057] Adopting the above technical solution can facilitate the adjustment of the installation angle of the main cable 3. During use, the main cable 3 is sequentially passed through the arc-shaped through groove and the circular ring holes 1.1.1 on the surface of the column top ring 1.1, and it is ensured that the main cable 3 protrudes a certain distance from the circular ring holes 1.1.1. The main cable 3 is fixed and tensioned using a locking anchor and an extrusion anchor to complete the installation of the main cable 3. The column top ring 1.1 is not limited to a circular shape and can also be a polygonal structure.

[0058] As Figure 3 and Figure 5 shown, in this embodiment, the support system further includes: a column top ring plug plate 1.2 provided at both ends of the column top ring 1.1; a main cable transition baffle 9 provided with through holes adapted to the circular ring holes 1.1.1, and the main cable transition baffle 9 forms an arc-shaped surface on the side where it fits the circumferential surface of the column top ring 1.1.

[0059] Adopting the above technical solution can help reduce the wear on the surface of the column top ring 1.1. By setting the main cable transition baffle 9 on the surface of the column top ring 1.1 and providing an arc-shaped surface on one side of the main cable transition baffle 9, the main cable transition baffle 9 can be fully fitted with the surface of the column top ring 1.1. By setting the main cable transition baffle 9 between the locking anchor and the column top ring 1.1, it can prevent line contact between the locking anchor and the column top ring 1.1, avoid the situation of excessive stress concentration, and prevent the surface of the column top ring 1.1 from being indented under pressure.

[0060] As Figure 2 and Figure 3 shown, in this embodiment, both ends of the cable connection bottom plate 12 are bent at a certain angle to form bent segments.

[0061] Adopting the above technical solution can improve the structural strength of the cable connection base plate 12. By bending the two ends of the cable connection base plate 12, its anti-bending ability is improved, preventing the cable connection base plate 12 from bending in the middle due to the tension of the stay cable.

[0062] As Figure 6 shown, in this embodiment, the limiting cushion block 11 is provided with a concave groove adapted to the pin shaft 10 at one end where it fits the pin shaft 10;

[0063] Adopting the above technical solution can increase the contact area between the limiting cushion block 11 and the pin shaft 10, prevent the surface of the pin shaft 10 from deforming due to excessive stress concentration, and improve the structural strength.

[0064] Working principle:

[0065] Step 1: As Figure 1 and Figure 4 shown, use bolts and nuts to install the inter-column support A4 and the inter-column support B5 on the side column 1.6 of the side column assembly 1 and the rear column 2 respectively;

[0066] Step 2: As Figure 3 shown, pass the main cable 3 through the appropriate circular hole 1.1.1 on the surface of the column top ring 1.1 and the through hole on the surface of the main cable transition baffle 9 in sequence, and fix the extrusion anchor on the main cable 3;

[0067] Step 3: As Figure 2 and Figure 3 shown, the lower part of the stay cable is connected to the arc support plate 13 on the side anchor base weldment 8 through the U-shaped fastening device 7 composed of the U-shaped bolt 16 and the cable connection base plate 12;

[0068] Step 4: As Figure 2 , Figure 5 and Figure 6 shown, the pin shaft 10 at the upper part of the stay cable device 6 is pre-placed in the card slot 1.9 of the stay cable vertical plate 1.5, and ensure that the limiting cushion block 11 is between the two stay cable vertical plates 1.5;

[0069] Step 5: As Figure 2 and Figure 3 shown, the lower part of the stay cable is rigidly connected to the cable connection base plate 12, and the nut on the U-shaped bolt 16 is adjusted to make the stay cable shorter, so that the stay cable is straightened and stressed, thus completing the installation.
