Description

Technical Field

[0001] The present application relates to the field of photovoltaic technology, and more specifically, to an end bracket structure and a flexible photovoltaic bracket system. Background Art

[0002] The cable-structured photovoltaic bracket is a battery assembly support frame used in solar power stations, which mainly includes end brackets, middle brackets and the middle cables supported by them, and wind-resistant systems. As an important component supporting the main cable, the end bracket mainly constrains both ends of the main cable and provides tensioning conditions for the prestressing of the main cable. The end bracket is usually composed of columns, compression piles, diagonal members and tensile piles. The columns convert the tension of the main cable into the diagonal tension of the diagonal member through the column head pin node, and the lower end of the diagonal member is connected to the tensile pile.

[0003] In the prior art, the end bracket usually has two columns, which are connected to the main cable through column head pin nodes respectively. However, since the two columns are independent of each other, the wind resistance and stability of the entire end bracket are poor, and its adaptability to complex terrain is weak. At the same time, its unstable installation structure will also cause certain risks in the process of tightening the main cable.

[0004] In addition, the column head is usually fixed at the top of the column by welding or bolting, and is connected to the connecting assembly connecting the main cable and the diagonal member through the column head. This connection method usually requires processing techniques such as cutting, bolting, and welding and assembling of steel plates. The production process is relatively complicated and the number of parts is large, resulting in low assembly quality and efficiency and high cost.

[0037] The core of the present application is to provide an end bracket structure to improve the assembly efficiency of the end bracket while ensuring the stability of the end bracket.

[0038] Another core of the present application is to provide a flexible photovoltaic support system having the above-mentioned end support structure.

[0039] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0040] The cable-structured photovoltaic bracket is a battery assembly support frame used in solar power stations, which mainly includes end brackets, middle brackets and the middle cables supported by them, and wind-resistant systems. As an important component supporting the main cable, the end bracket mainly constrains both ends of the main cable and provides tensioning conditions for the prestressing of the main cable. The end bracket is usually composed of columns, compression piles, diagonal members and tensile piles. The columns convert the tension of the main cable into the diagonal tension of the diagonal member through the column head pin node, and the lower end of the diagonal member is connected to the tensile pile.

[0041] In the prior art, the end bracket usually has two columns, which are connected to the main cable through column head pin nodes respectively. However, since the two columns are independent of each other, the wind resistance and stability of the entire end bracket are poor, and its adaptability to complex terrain is weak. At the same time, its unstable installation structure will also cause certain risks in the process of tightening the main cable.

[0042] In addition, the column head is usually fixed at the top of the column by welding or bolting, and is connected to the connecting assembly connecting the main cable and the diagonal member through the column head. This connection method usually requires processing techniques such as cutting, bolting, and welding and assembling of steel plates. The production process is relatively complicated and the number of parts is large, resulting in low assembly quality and efficiency and high cost.

[0043] For this reason, Figure 1As shown, the embodiment of the present application discloses an end bracket structure, including a column 200 and a connecting assembly 401. By providing at least two reinforcing members 201 intersecting at a preset angle between the two columns 200, the two columns 200 are connected to each other, thereby ensuring the stability of the columns 200, thereby improving the wind resistance and stability of the entire end bracket. At the same time, by providing an installation cavity 202 on the column 200 to accommodate the connecting assembly 401, there is no need to add additional parts to adapt to the connecting assembly 401, thereby reducing the number of parts, simplifying the installation process, ensuring assembly quality, and improving assembly efficiency. In addition, by abutting the bottom wall of the limiting member 403 and the limiting notch 4021, the limiting member 403 and the main shaft 402 have a large contact area, thereby ensuring the stability of the connection of the main cable 500.

[0044] The following will be combined Figures 1 to 6 The end bracket structure disclosed in the embodiment of the present application is specifically explained and illustrated.

[0045] Among them, Figures 1 to 3 As shown, the column 200 is arranged on the first pile body 100, and there are two columns 200, at least two reinforcement members 201 are connected between the two columns 200, and the two reinforcement members 201 are arranged to intersect at a preset angle, so that an overall structure of a triangular frame is formed between the reinforcement members 201 and the columns 200, so that the two columns 200 are connected to each other, ensuring the stability of the columns 200, thereby improving the wind resistance and stability of the entire end bracket.

[0046] In some embodiments, Figure 1 and Figure 2As shown, the column 200 is the main supporting component of the end bracket structure. It is preferably made of a square steel pipe made of high-strength steel so that the column 200 has good bearing capacity and wind resistance. The bottom of the column 200 is equipped with a connecting part 205. The column 200 can be fixedly connected to the first pile body 100 through the connecting part 205. The connecting part 205 is usually made of steel plates or cast steel parts to ensure sufficient strength and durability. Compared with the column 200, the connecting part 205 is a small component and has a better degree of freedom in structural design. The connecting portion 205 includes reinforcing plates 2052 arranged on both sides of the column 200 and a connecting bottom plate 2051 located on the bottom surface of the column 200, and the two sides of the reinforcing plate 2052 can be bent to form a bent portion, so that an installation space for installing the reinforcing plate 2052 is formed between the two bent portions, so that the reinforcing plate 2052 can be easily fixed to one side of the column 200 by fasteners such as bolts, and the connecting bottom plate 2051 can be fixed to the bottom surface of the column 200 by welding, and an escape space for fixing the connecting bottom plate 2051 and the first pile body 100 is formed between the bent portions of the two relatively arranged reinforcing plates 2052, so that the connecting bottom plate 2051 can be easily fixed to the first pile body 100 by fasteners such as bolts, thereby achieving the fixation of the column 200 and the first pile body 100. Of course, the reinforcing plate 2052 can also be fixed to one side of the column 200 by welding, or four reinforcing plates 2052 are used and are respectively arranged on the four sides of the column 200, which is not limited in this article. It should be noted that the column 200 can also be made of round steel pipes or other metal pipes according to actual conditions, which is not limited in this article.

[0047] In the above embodiment, if Figure 1 and Figure 2 As shown, the first pile body 100 serves as a supporting base, which may be a precast concrete pile, a steel pile or other types of piles, and the first pile body 100 is usually partially buried underground to provide stable support.

[0048] In some embodiments, Figure 1 and Figure 2 As shown, there are two reinforcement members 201, and the two reinforcement members 201 intersect at the same intersection of the column 200 at a preset angle, so that a triangular frame structure is formed between the reinforcement member 201 and the column 200. The preset angle can be 30°, 45°, 60°, etc. For ease of assembly, the reinforcement member 201 and the column 200 can be movably connected, and a locking mechanism is provided between the reinforcement member 201 and the column 200 to lock the connection between the reinforcement member 201 and the column 200.

[0049] In some embodiments, Figure 1 and Figure 2As shown, a connecting sleeve 203 is provided at the end of the reinforcement 201, and the connecting sleeve 203 forms a space for accommodating the column 200, and the connecting sleeve 203 is slidably matched with the column 200. At the same time, the locking mechanism includes a first mounting hole provided on the column 200 and a second mounting hole provided on the connecting sleeve 203, and the second mounting hole is adapted to the first mounting hole, so that the column 200 and the connecting sleeve 203 can be connected and fixed by fasteners such as bolts. In order to ensure the reliability of the connection between the connecting sleeve 203 and the column 200, a plurality of second mounting holes are distributed on the two oppositely arranged side surfaces of the connecting sleeve 203, and a plurality of first mounting holes adapted to the second mounting holes are provided at positions corresponding to the second mounting holes on the column 200, so that the column 200 and the connecting sleeve 203 can be connected and fixed by fasteners such as bolts, thereby improving the connection strength between the connecting sleeve 203 and the column 200, and further ensuring the reliability of the connection between the connecting sleeve 203 and the column 200. In addition, in order to facilitate the assembly of the reinforcement 201, in the height direction of the column 200, the number of the first mounting holes of the column 200 can be greater than the number of the second mounting holes on the connecting sleeve 203, so that when the reinforcement 201 is installed, the installation position of the end of the reinforcement 201 can be adjusted to facilitate the assembly of the reinforcement 201.

[0050] In some embodiments, the locking mechanism may also be provided with a spring protrusion in the first mounting hole. When the reinforcement 201 is assembled with the column 200, it is only necessary to move the connecting sleeve 203 on the column 200. When the connecting sleeve 203 contacts the spring protrusion, the connecting sleeve 203 is continued to be moved. At this time, the spring protrusion is compressed into the first mounting hole until the second mounting hole on the connecting sleeve 203 is aligned with the first mounting hole. The spring protrusion is restored to a natural state under the action of elastic force, and the spring protrusion is snapped into the second mounting hole on the connecting sleeve 203. When the end position of the reinforcement 201 needs to be adjusted, it is only necessary to press the spring protrusion into the first mounting hole and move the connecting sleeve 203 at the same time so that the spring protrusion is snapped into the second mounting hole at the target position. It should be noted that, in the above embodiment, the number of the first mounting holes on the column 200 corresponding to the second mounting holes can be one, and a spring protrusion can be set in the first mounting hole. At the same time, the number of the second mounting holes on the connecting sleeve 203 can be two, three, four or more, and each second mounting hole can be arranged along the vertical arrangement of the connecting sleeve 203, that is, the height direction of the column 200, so that the connecting sleeve 203 can be moved along the height direction of the column 200 to achieve the adjustment of the installation position of the end of the reinforcement 201. Of course, the number of the first mounting holes on the column 200 corresponding to the second mounting holes can also be two, three, four or more, and a spring protrusion can be set in some or all of the first mounting holes. At the same time, the second mounting holes of the connecting sleeve 203 are set corresponding to the first mounting holes, and the number of the second mounting holes of the connecting sleeve 203 distributed along the vertical direction can be greater than the number of the first mounting holes, so that the connecting sleeve 203 can be moved and adjusted along the height direction of the column 200.

[0051] In some embodiments, Figure 1 and Figure 2As shown, the connection sleeve 203 may adopt a U-shaped structure, and the connection sleeve 203 has an opening 2031, so that the connection sleeve 203 is connected to the column 200, and the reinforcement member 201 is hinged to the side of the connection sleeve 203 away from the opening 2031. Specifically, a support plate 2012 is vertically arranged on the side of the connection sleeve 203 away from the opening 2031, and the support plate 2012 can be fixed to the connection sleeve 203 by welding, and an ear plate 2011 can be fixed to the end of the reinforcement member 201, and the ear plate 2011 is hinged and fixed to the support plate 2012, so that there can be a relative displacement between the reinforcement member 201 and the column 200, so as to absorb and disperse the load under the action of earthquake, wind and other loads, thereby improving the safety of the end support structure, and reducing the stress concentration of the end support structure, which is conducive to improving the stability and toughness of the end support structure. It should be noted that in order to ensure the overall stability of the connecting sleeve 203 and the support plate 2012, a plurality of reinforcing ribs can be welded between the support plate 2012 and the connecting sleeve 203 to improve the connection strength between the connecting sleeve 203 and the support plate 2012, thereby ensuring the overall stability of the connecting sleeve 203 and the support plate 2012.

[0052] In the above embodiment, the number of the reinforcement members 201 may be, but not limited to, two, and may also be three, four or more. At the same time, the reinforcement members 201 may be connected end to end in sequence, and a preset angle may be formed between two adjacent reinforcement members 201. Of course, the reinforcement members 201 may also be arranged in pairs to form an intersection at the middle position of the reinforcement members 201, thereby forming a scissor frame structure. The specific structural form and number of the reinforcement members 201 may be determined according to actual conditions, and are not limited herein.

[0053] It should be noted that, in the above-mentioned embodiment, the reinforcement member 201 may be a hollow steel pipe, an I-shaped steel, a channel steel, etc., which is not limited herein.

[0054] like Figures 3 to 6As shown, the column 200 is provided with an installation cavity 202 for accommodating the connection assembly 401, and the connection assembly 401 includes a main shaft 402 and a stopper 403. Among them, a through hole is opened at the center of the main shaft 402, so that the main cable 500 can pass through the through hole, and at the same time, two side walls of the installation cavity 202 that are arranged opposite to each other are respectively provided with through holes for the main shaft 402 to pass through, and a strip hole 2021 for the main cable 500 to pass through is provided on the side wall of the installation cavity 202 that is perpendicular to the surface where the through hole is located. During assembly, the two ends of the main shaft 402 are respectively passed through the through holes and locked by the safety pin 4022 to prevent the main shaft 402 from falling out of the through hole, thereby fixing the main cable 500 on the column 200. At the same time, a stopper 403 is sleeved on the end of the main cable 500. By passing the main cable 500 through the stopper 403, the main cable 500 can be prevented from slipping out of the through hole of the main shaft 402, thereby ensuring the reliability of the connection of the main cable 500. It can be seen from the above embodiment that by providing the installation cavity 202 for accommodating the connection component 401 on the column 200, there is no need to add additional parts to adapt to the connection component 401, which reduces the number of parts, simplifies the installation process, ensures the assembly quality, improves the assembly efficiency, and reduces the cost. It should be noted that the strip hole 2021 can be a strip round hole, a rectangular hole, etc., or a round hole or a square hole for the main cable 500 to pass through can be provided on the side wall of the installation cavity 202 perpendicular to the surface where the perforation is located. It only needs to meet the requirements that the main cable 500 and the stopper 403 can move within a certain angle range, and this is not limited in this article.

[0055] In the above embodiment, the holes in the column 200 may be opened by, but not limited to, laser cutting, or by steel structure thermal cutting, flame cutting, cold cutting, or water cutting, which is not limited herein.

[0056] In some embodiments, Figure 5 and Figure 6 As shown, a limiting notch 4021 is provided on the main shaft 402 to cooperate with the limiting member 403, and the through hole of the main shaft 402 is located on the bottom wall of the limiting notch 4021, so that the main cable 500 passes through the through hole of the limiting notch 4021 and the limiting member 403 in sequence, and the limiting member 403 abuts against the bottom wall of the limiting notch 4021 to lock the main cable 500 and prevent the main cable 500 from escaping from the through hole on the main shaft 402. The bottom wall of the limiting notch 4021 is a plane, so as to ensure that the limiting member 403 has a large contact area with the bottom wall of the limiting notch 4021, avoid stress concentration, and keep the main cable 500 in a stable locked state.

[0057] In some embodiments, Figures 4 to 6As shown, the limiting member 403 may include an end 4031, and the end 4031 may adopt a stepped design so that the small diameter end of the end 4031 can extend into the installation cavity 202 through the strip hole 2021 and abut against the bottom wall of the limiting notch 4021, while the large diameter end of the end 4031 is exposed outside the installation cavity 202, so as to facilitate the connection and fixation between the end 4031 and the main rope 500 through threaded matching.

[0058] like Figure 3 As shown, the end support structure includes an inclined brace 400, and the inclined brace 400 has two ends arranged oppositely. For the convenience of understanding, the two ends of the inclined brace 400 are defined as a first end and a second end, respectively. Among them, the first end of the inclined brace 400 is connected to the second pile body 300, and the second end of the inclined brace 400 is rotatably connected to the main shaft 402 through an inclined brace sleeve 404 to form an inclined cable structure. The inclined cable structure design can transfer the load to the column 200, so that the flexible photovoltaic support system has a large span capacity, so that it can adapt to various terrains and complex geological conditions. Specifically, one end of the inclined brace sleeve 404 is rotatably connected to the main shaft 402, and the other end of the inclined brace sleeve 404 tightens the inclined brace 400 to provide the required tension, and the inclined brace 400 can be relatively rotatably connected to the main shaft 402, which is conducive to absorbing and dispersing the load caused by wind load, earthquake, etc., thereby improving the wind resistance and earthquake resistance of the end support structure.

[0059] In the above-mentioned embodiment, the inclined brace 400 may be a component that can provide a certain pre-tension force, such as an inclined cable, a steel wire rope, an inclined steel pipe, or an inclined steel bar, which is not limited herein.

[0060] In some embodiments, Figure 3 As shown, the second pile body 300 has the same structure and properties as the first pile body 100, and is also partially buried underground. At the same time, the first end of the inclined brace 400 can be cast and formed in the second pile body 300 to be fixedly connected to the second pile body 300, and the second end of the inclined brace 400 is rotatably connected to the main shaft 402 through the inclined brace sleeve 404. In addition, in order to ensure the overall stability of the pile foundation, the first pile body 100 and the second pile body 300 can be connected through a reinforcing beam 301, and the reinforcing beam can be a reinforced concrete structure, a steel structure, etc., so that the first pile body 100 and the second pile body 300 are connected to each other, thereby ensuring the overall stability of the pile foundation. Of course, the first pile bodies 100 at the bottom of the two columns 200 can also be connected through a reinforcing beam 301, and the two second pile bodies 300 can also be connected through a reinforcing beam 301, so as to improve the stability and bearing capacity of the entire pile foundation, reduce uneven settlement, and thus ensure the overall stability of the end support structure.

[0061] In some embodiments, Figure 4As shown, the inclined sleeve 404 may include a connecting plate 4041 and two pivot bolts 4042. The connecting plate 4041 is the central force-bearing component of the inclined sleeve 404 and can be used to transmit the force of the inclined member 400 to the connecting assembly 401. The connecting plate 4041 can be made of metal material to have sufficient strength and rigidity, and the two pivot bolts 4042 are symmetrically arranged on the connecting plate 4041 to fix the inclined sleeve 404 to the main shaft 402. The opening ends 4043 of the two pivot bolts 4042 are symmetrically sleeved on both ends of the main shaft 402. The design structure of the pivot bolts 4042 allows the inclined member 400 to adjust the distance and tension to a certain extent in the length direction. It can be seen from the above embodiments that the tensioning force of the diagonal brace 400 is transmitted to the main shaft 402 through the diagonal brace sleeve 404 and acts on the main cable 500. The diagonal brace 400 is directly connected to the connecting plate 4041, and the two movable bolts 4042 transmit the tensioning force to the symmetrical two end positions of the main shaft 402. This structure applies a more uniform tensioning effect to the main cable 500, making the main cable 500 more stable.

[0062] In some embodiments, Figure 3 and Figure 4 As shown, a reinforcing cover plate 204 is also provided on the top of the column 200, and a reinforcing hole is provided on the reinforcing cover plate 204 at a position corresponding to the through hole of the installation cavity 202, so that the main shaft 402 can pass through the reinforcing hole and be locked by the safety pin 4022.
