Description

[0001] This application is a divisional application of the invention with the application date of October 18, 2024, the invention name of which is “An end bracket structure and flexible photovoltaic bracket system” and the application number is 202411456515.2. Technical Field

[0002] 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

[0003] 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.

[0004] 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.

[0005] 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.

[0006] Therefore, how to improve the assembly efficiency of the end bracket while ensuring the stability of the end bracket has become a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0040] The core of this application lies in providing an end bracket structure to ensure the stability of the end bracket while improving the assembly efficiency of the end bracket.

[0041] Another core of this application lies in providing a flexible photovoltaic support system with the above-mentioned end bracket structure.

[0042] Next, the technical solutions in the embodiments of this application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without any creative work belong to the scope of protection of this application.

[0043] The cable structure photovoltaic support is a support for battery modules used in solar power plants, which mainly includes an end bracket, a middle bracket, the middle cables supported by them, and a wind resistance system. As an important component for supporting the main cable, the main function of the end bracket is to restrain both ends of the main cable and provide the tensioning condition for the prestress of the main cable. The end bracket usually consists of columns, compression piles, stay members, and tension piles. Among them, the column converts the tension of the main cable into the inclined tension of the stay member through the pin joint at the column head, and the lower end of the stay member is connected to the tension pile.

[0044] In the prior art, there are usually two columns for the end bracket, which are respectively connected to the main cable through the pin joints at the column heads. However, since the two columns are independent of each other, the wind resistance and stability of the entire end bracket are poor, the adaptability to complex terrains is weak, and the unstable installation structure will also pose certain risks during the tensioning process of the main cable.

[0045] In addition, the column head is usually fixed at the top of the column by welding or bolting, and is connected to the connection assembly for connecting the main cable and the stay member. This connection method usually requires processing techniques such as cutting of steel plates, bolt connection, and steel plate welding and assembly. Its manufacturing process is relatively complex, and the number of parts is large, resulting in low assembly quality and efficiency and high costs.

[0046] Therefore, as Figure 1As shown in the figure, an embodiment of the present application discloses an end bracket structure, including a column 200 and a connection component 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, 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 connection component 401, there is no need to add additional parts to match the connection component 401, reducing the number of parts, simplifying the installation process, ensuring the assembly quality, and improving the assembly efficiency. In addition, by making the limiting member 403 abut against the bottom wall of the limiting notch 4021, the limiting member 403 has a large contact area with the main shaft 402, ensuring the stability of the connection of the main cable 500.

[0047] Next, the end bracket structure disclosed in the embodiments of the present application will be specifically explained and described. Figures 1 to 6

[0048] Among them, as Figures 1 to 3 shown, the column 200 is arranged on the first pile body 100, and there are two columns 200. At least two reinforcing members 201 are connected between the two columns 200. At the same time, the two reinforcing members 201 intersect at a preset angle, so that a triangular frame integral structure is formed between the reinforcing member 201 and the column 200, thereby connecting the two columns 200 to each other, ensuring the stability of the column 200, and further improving the wind resistance and stability of the entire end bracket.

[0049] In some embodiments, as Figure 1 and Figure 2As shown, the column 200 serves as the main supporting component of the end bracket structure. It is preferably a square steel pipe made of high-strength steel to enable the column 200 to have good load-bearing capacity and wind resistance. A connecting part 205 is assembled at the bottom of the column 200. The column 200 can be fixedly connected to the first pile 100 through the connecting part 205. The connecting part 205 is usually made of steel plate or cast steel to ensure sufficient strength and durability. The connecting part 205 is a small component compared to the column 200, and it has better structural design freedom. Among them, the connecting part 205 includes reinforcing plates 2052 oppositely arranged on both sides of the column 200 and a connecting bottom plate 2051 located at the bottom surface of the column 200. The two sides of the reinforcing plate 2052 can be bent to form bent parts, so as to form an installation space for installing the reinforcing plate 2052 between the two bent parts, thereby facilitating the fixing of the reinforcing plate 2052 to one side of the column 200 through fasteners such as bolts. At the same time, the connecting bottom plate 2051 can be fixedly welded to the bottom surface of the column 200, and an avoidance space for fixing the connecting bottom plate 2051 to the first pile 100 is formed between the bent parts of the two oppositely arranged reinforcing plates 2052, thereby facilitating the fixing of the connecting bottom plate 2051 to the first pile 100 through fasteners such as bolts, and then realizing the fixation between the column 200 and the first pile 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 side surfaces of the column 200, which is not limited herein. It should be noted that the column 200 can also be a circular steel pipe or other metal pipes according to actual situations, which is not limited herein.

[0050] In the above embodiment, as Figure 1 and Figure 2 shown, the first pile 100 serves as a support base. It can be a precast concrete pile, a steel pile or other types of piles, and the first pile 100 is usually partially buried underground to provide stable support.

[0051] In some embodiments, as Figure 1 and Figure 2 shown, there are two reinforcing members 201, and the two reinforcing members 201 intersect at the same intersection position of the column 200 at a preset angle, so as to form an overall structure of a triangular frame between the reinforcing members 201 and the column 200. Among them, the preset angle can be 30°, 45°, 60°, etc. For the convenience of assembly, the reinforcing members 201 and the column 200 can be movably connected, and a locking mechanism is arranged between the reinforcing members 201 and the column 200 to lock the connection between the reinforcing members 201 and the column 200.

[0052] In some embodiments, as Figure 1 and Figure 2As shown, a connecting sleeve 203 is provided at the end of the reinforcement member 201. The connecting sleeve 203 forms a space for accommodating the column 200, and the connecting sleeve 203 is in sliding fit 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. 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 both opposite sides of the connecting sleeve 203. At the same time, a plurality of first mounting holes adapted to the second mounting holes are provided at the 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 a plurality of 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 member 201, in the height direction of the column 200, the number of the first mounting holes on the column 200 can be greater than the number of the second mounting holes on the connecting sleeve 203, so that when the reinforcement member 201 is installed, the installation position of the end of the reinforcement member 201 can be adjusted, facilitating the assembly of the reinforcement member 201.

[0053] In some embodiments, the locking mechanism may also be configured with spring protrusions disposed within the first mounting holes. When assembling the reinforcement member 201 with the column 200, it is only necessary to move the connecting sleeve 203 along the column 200. When the connecting sleeve 203 comes into contact with the spring protrusions, continue to move the connecting sleeve 203. At this time, the spring protrusions are compressed into the first mounting holes until the second mounting holes on the connecting sleeve 203 are aligned with the first mounting holes. Then, the spring protrusions return to their natural state under the action of elastic force, and at the same time, the spring protrusions snap into the second mounting holes on the connecting sleeve 203. When it is necessary to adjust the end position of the reinforcement member 201, it is only necessary to press the spring protrusions into the first mounting holes and move the connecting sleeve 203 simultaneously, so that the spring protrusions snap into the second mounting holes at the target position. It should be noted that in the above embodiments, the number of the first mounting holes corresponding to the second mounting holes on the column 200 may be one, and spring protrusions are disposed within the first mounting holes. At the same time, the number of the second mounting holes on the connecting sleeve 203 may be two, three, four or more, and each of the second mounting holes may be arranged vertically along the connecting sleeve 203, that is, along the height direction of the column 200, so that the connecting sleeve 203 can realize the adjustment of the installation position of the end of the reinforcement member 201 by moving along the height direction of the column 200. Of course, the number of the first mounting holes corresponding to the second mounting holes on the column 200 may also be two, three, four or more, and spring protrusions may be disposed within some or all of the first mounting holes. At the same time, the second mounting holes of the connecting sleeve 203 are correspondingly arranged with the first mounting holes, and the number of the second mounting holes vertically distributed on the connecting sleeve 203 may be greater than the number of the first mounting holes, so as to facilitate the movement adjustment of the connecting sleeve 203 along the height direction of the column 200.

[0054] In some embodiments, such as Figure 1 and Figure 2As shown, the connecting sleeve 203 can adopt a U-shaped structure, and the connecting sleeve 203 has an opening 2031 for connecting the connecting sleeve 203 with the column 200. At the same time, the reinforcing member 201 is hinged to the side of the connecting sleeve 203 away from the opening 2031. Specifically, a support plate 2012 is vertically provided on the side of the connecting sleeve 203 away from the opening 2031, and the support plate 2012 can be fixed to the connecting sleeve 203 by welding. At the same time, an ear plate 2011 can be fixed at the end of the reinforcing member 201, and the ear plate 2011 is hinged and fixed to the support plate 2012, so that a relative displacement can exist between the reinforcing member 201 and the column 200 to absorb and disperse loads under the action of loads such as earthquakes and winds, thereby improving the safety of the end bracket structure. At the same time, the stress concentration of the end bracket structure can be reduced, which is beneficial to improving the stability and toughness of the end bracket 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.

[0055] In the above embodiment, the number of the reinforcing members 201 can be two, but not limited to two, and can also be three, four or more. At the same time, the reinforcing members 201 can be connected end to end in sequence, and a preset included angle is provided between two adjacent reinforcing members 201. Of course, the reinforcing members 201 can also be arranged in a pairwise cross manner to form an intersection at the middle position of the reinforcing members 201, thereby forming a scissors frame structure. The specific structural form and number of the reinforcing members 201 can be determined according to the actual situation, and are not limited herein.

[0056] It should be noted that in the above embodiment, the reinforcing member 201 can adopt a hollow steel pipe, an I-shaped steel, a channel steel, etc., which are not limited herein.

[0057] Such as 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.

[0058] 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.

[0059] 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.

[0060] In some embodiments, Figures 4 to 6As shown, the limiting member 403 may include a head 4031, and the head 4031 may adopt a stepped design, so that the small-diameter end of the head 4031 can extend into the installation cavity 202 through the strip-shaped hole 2021 and abut against the bottom wall of the limiting notch 4021. At the same time, the large-diameter end of the head 4031 is exposed outside the installation cavity 202 to facilitate the connection and fixation between the head 4031 and the main cable 500 through threaded cooperation.

[0061] As Figure 3 shown, the end support structure includes a stay cable member 400. The stay cable member 400 has two opposite ends. For the convenience of understanding, the two ends of the stay cable member 400 are respectively defined as the first end and the second end. Among them, the first end of the stay cable member 400 is connected to the second pile body 300, and the second end of the stay cable member 400 is rotatably connected to the main shaft 402 through a stay cable sleeve 404 to form a stay cable structure. Through the design of the stay cable structure, the load can be transmitted to the column 200, so that the flexible photovoltaic support system has a large span capacity, and thus can adapt to various terrains and geological complex working conditions. Specifically, one end of the stay cable sleeve 404 is rotatably connected to the main shaft 402, and the other end of the stay cable sleeve 404 tightens the stay cable member 400 to provide the required tension, and the stay cable member 400 is rotatably connected to the main shaft 402, which is beneficial to absorbing and dispersing the loads caused by wind loads, earthquakes, etc., thereby improving the wind resistance and seismic resistance of the end support structure.

[0062] In the above embodiment, the stay cable member 400 may adopt components such as stay cables, steel wires, stay steel pipes, stay steel bars, etc. that can provide a certain pre-tension, which is not limited herein.

[0063] In some embodiments, as Figure 3 shown, the second pile body 300 has the same structure and properties as the first pile body 100, and it is also partially buried underground. At the same time, the first end of the stay cable member 400 can be cast in the second pile body 300 to be fixedly connected to the second pile body 300, while the second end of the stay cable member 400 is rotatably connected to the main shaft 402 through the stay cable 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 by a strengthening beam 301, and the strengthening beam can adopt 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 bottoms of the two columns 200 can also be connected by a strengthening beam 301, and at the same time, the second pile bodies 300 can also be connected by a strengthening beam 301 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.

[0064] In some embodiments, as 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.

[0065] 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.
