[0034] The core of the utility model is to disclose an end bracket structure to improve its adaptability to complex terrain, reduce its assembly difficulty and improve the locking effect.

[0035] Another core of the utility model is to disclose a flexible photovoltaic system using the above-mentioned end bracket structure.

[0036] In order to make the technical personnel in this field better understand the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the contents of the utility model described in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the utility model described in the claims.

[0037] like Figure 1-8As shown, the end bracket structure provided by the embodiment of the utility model includes a column 10, a connecting part 20, a first pile body 30, a second pile body 40 and an upper node 70, wherein the column 10 is the main supporting component of the end bracket structure, which is preferably made of high-strength steel to have good bearing capacity and wind pressure resistance, and the bottom of the column 10 is equipped with a connecting part 20, which is used to achieve a fixed connection between the column 10 and the first pile body 30, and is usually made of steel plates or cast steel parts to ensure sufficient strength and durability. Compared with the column 10, the connecting part 20 is a small component and has a better degree of freedom in structural design. The design of the connecting part 20 is preferably to achieve stable fixation with the first pile body 30, and at the same time, it has a vertically upward extension structure for the column 10 to be mounted. After the connection part 20 is set, the column 10 can be mounted on the outer periphery of the connection part 20 to achieve pre-installation, and then the column 10 can be locked with the connection part 20 by bolts and other structures to complete the setting of the column 10.

[0038] The first pile body 30 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 30 is usually partially buried underground to provide stable support. The second pile body 40 has the same structure and properties as the first pile body 30, and is also partially buried underground. At the same time, the second pile body 40 is fixedly connected to one end of the inclined cable 60, and the second end of the inclined cable 60 is fixedly connected to the main cable 50 through the upper node 70 to tighten the main cable 50. The upper node 70 is a connecting force structure, one side of which is a cavity structure and is sleeved on the outer periphery of the column 10. Similarly, the upper node After the point 70 is sleeved on the outer periphery of the column 10, it can also be locked and fixed with the column 10 by means of the connecting part 20 such as bolts. When setting the end bracket structure, it is only necessary to first set the first pile body 30 and the second pile body 40 at the preset position, and then lock the connecting part 20 with the first pile body 30. After setting the column 10 by sleeved means, the column 10 and the connecting part 20 are locked to complete the construction of the main structure. The upper node 70 can also be sleeved first to be pre-installed on the top of the column 10, and then the construction personnel can lock it with bolts. The process is convenient and the construction efficiency is high.

[0039] The end bracket structure provided by the embodiment of the utility model adopts a split design and a sleeve pre-installed structure. When the end bracket structure is set up under relatively complex terrain, the first pile body 30 and the second pile body 40 can be set on the ground first. The pile body can be set up by the operator on the ground. After the pile body is set up, the connecting part 20 is fixedly set on the first pile body 30. The connecting part 20 with a relatively small structure is easy to design and fix. At the same time, the column 10 can be sleeved on the outer periphery of the connecting part 20 to achieve pre-installation, and then fixed and locked by bolts and other locking parts. Similarly, the upper section arranged at the top of the column 10 Point 70 can be sleeved on the outer periphery of the top of the column 10 for pre-installation. In the above structure, there is no need to consider the state of the column 10 when pouring the pile body, and the operator can conveniently construct on the ground. The independent structure of the connecting part 20 enables the operator to independently lock the connecting part 20 and the first pile body 30, without directly locking the higher column 10 and the pile body on the ground as in the prior art. The operation process is more convenient, and the locking action of the connecting part 20 is easier to operate. The subsequent setting of the column 10 and the assembly of the upper node 70 can be pre-installed by sleeve, thereby reducing the overall assembly difficulty and saving labor costs.

[0040] Furthermore, in some embodiments of the present invention, the connecting portion 20 specifically includes a connecting block 210, a supporting block 220 and a reinforcing plate 230, wherein the connecting block 210 serves as a core connecting point and is responsible for fixing and connecting with other structural members, namely the supporting block 220, and the supporting block 220 is designed as an L-shaped plate to provide necessary lateral support, and the two supporting blocks 220 are symmetrically arranged on both sides of the connecting block 210, and the stability of the structure is enhanced by bending outward. It should be noted that due to the setting of the connecting block 210, there is a certain distance between the two supporting blocks 220 after the setting, and it is preferred that a plurality of bolts are passed through and locked between the two support blocks 220 to enhance the overall structural strength.

[0041] The reinforcing plate 230 is designed as a right-angled triangle plate, which is arranged on each support block 220 and fixed to the bent edge of the support block 220 by welding to enhance the strength and rigidity of the entire structure. More preferably, the reinforcing plate 230 should cover the entire bending area of ​​the support block 220 to provide additional supporting force. Correspondingly, a groove is designed at the bottom of the column 10 to be inserted into the reinforcing plate 230 on the support block 220 through the groove when assembled with the connecting part 20, so that the column 10 can be smoothly inserted into the bottom position of the connecting part 20, thereby increasing the working height of the connecting part 20 and the column 10 and improving the connection stability.

[0042] In the end bracket structure provided in the embodiment of the utility model, the upper node 70 includes a main shaft 710, a seat 730, an end 740 and a diagonal sleeve 750, wherein the main shaft 710 is designed as a hollow metal tube, and its inner diameter is slightly larger than the outer diameter of the main cable 50 to facilitate the passage of the main cable 50, and the two sides of the main shaft 710 are respectively passed through the support plates, that is, the support plates are metal plates and are symmetrically arranged on both sides of the main shaft 710, and are locked with the main shaft 710 by the safety pin 720, and the thickness and size of the support plate are determined according to the diameter of the main shaft 710 and the required supporting force; the safety pin 720 is a metal partial structure of a cylindrical pin, which passes through the holes on the main shaft 710 and the support plate to fix the position of the support plate.

[0043] The base 730 and the end head 740 are arranged in a close fit, and the main rope 50 passes through the base 730 and the end head 740 at the same time. Specifically, the two opposite sides of the base 730 are an arc surface and a plane, respectively, wherein the arc surface of the base 730 fits the circular surface of the main shaft 710 to abut and limit the main shaft 710, and the plane of the base 730 abuts against the end head 740. The end head 740 is for the main rope 50 to pass through and is fixedly connected to the main rope 50. The main rope 50 is kept in a stably locked state through the forces on both sides of the base 730 and the main shaft 710.

[0044] The above structure realizes a stable locking connection of the main cable 50 on the upper node 70, and the inclined cable 60 is locked with the upper node 70 through the inclined sleeve 750 to tighten the main cable 50 through the upper node 70. Specifically, one end of the inclined sleeve 750 is rotatably connected to the main shaft 710, and the other end of the inclined sleeve 750 is arranged to tighten the inclined cable 60 to provide the required tension.

[0045] On the basis of the above-mentioned embodiment, the inclined pull sleeve 750 specifically includes a conversion plate 7510 and two movable bolts 7520. The conversion plate 7510 is used as the central force-bearing component of the inclined pull sleeve 750, and is used to convert and transmit the force of the inclined cable 60 to the upper node 70. The conversion plate 7510 is usually made of metal to have sufficient strength and rigidity, and the two movable bolts 7520 are symmetrically arranged on the conversion plate 7510 to fix the inclined pull sleeve 750 to the main shaft 710, and the open ends of the two movable bolts 7520 are It is symmetrically sleeved on both sides of the main shaft 710; the design structure of the movable bolt 7520 allows the inclined cable 60 to be adjusted to a certain extent in the length direction in terms of distance and tension, and in the above structure, the tensioning force of the inclined cable 60 is transmitted to the main shaft 710 through the inclined sleeve 750 and acts on the main cable 50. The inclined cable 60 is directly connected to the conversion plate 7510, and the two movable bolts 7520 transmit the tensioning force to the symmetrical two sides of the main shaft 710. This structure applies a more uniform tensioning effect to the main cable 50, making the main cable 50 more stable.

[0046] In order to improve the stability of the end bracket structure, in some embodiments of the present invention, a reinforcement member 80 is further provided between two adjacent columns 10. The reinforcement member 80 may be a profile structure, such as angle steel, channel steel or C-shaped steel, etc., so as to have good mechanical strength and stability. The two ends of the reinforcement member 80 are respectively fixedly connected to the side walls of the column 10 through the bottom plate 820 and the ear plate 810 to enhance the connection strength between the columns 10 and the stability of the overall structure. The ear plate 810 is a metal plate, one end of which is embedded in the reinforcement member 80 and welded and fixed to form a reinforcement member 80 and the ear plate 810. The bottom plate 820 is an integral structure, and the other end is designed with a bolt hole for bolt connection with the bottom plate 820. The bottom plate 820 is also a metal plate with multiple bolt holes for locking connection with the ear plate 810 and the side wall of the column 10. Correspondingly, bolt holes are reserved on the side wall of the column 10 for fixing with the bottom plate 820. The bottom plate 820 is fixed to the side wall of the column 10 by bolts. The position of the bottom plate 820 on the column 10 is adjusted as needed to meet the structural reinforcement requirements at different positions. The reinforcement member 80 can connect two adjacent columns 10 into an integral structure, thereby improving its setting stability.

[0047] In order to further optimize the above technical solution, it is preferred to set at least two reinforcement members 80 between two adjacent columns 10 to provide stronger support and stability. These reinforcement members 80 can be of the same size and shape, or reinforcement members 80 of different sizes and shapes can be used according to actual needs. It should be particularly noted that the fixing points of the two reinforcement members 80 on one of the columns 10 are located at the same point, which means that the two reinforcement members 80 can share a base plate 820 on a single column 10 to reduce the use of materials. At the same time, the two reinforcement members 80 cooperate with another column 10 to form a stable triangular structure to enhance the integrity of the two columns 10 and the stability of the structure.

[0048] Furthermore, in the end bracket structure provided in the embodiment of the utility model, the connecting part 20 and the first pile body 30 are locked and fixed by a plurality of pairs of anchor bolts 310 which are U-shaped as a whole, that is, a pair of anchor bolts 310 are configured in a U shape, and the connecting part 20 is fixedly connected to the first pile body 30 by a plurality of pairs of anchor bolts 310, and the end position of the anchor bolt 310 extending out of the first pile body 30 is arranged through the connecting part 20, and is locked and connected to the connecting part 20 by a pad and a nut. The structural design of the anchor bolt 310 can ensure that it cannot be pulled out of the first pile body 30, so that the connecting part 20 can be stably connected to the first pile body 30. At the same time, the fixing method of the pad and the nut avoids the anchor bolt 310 from directly acting on the connecting part 20 and causing wear to the connecting part 20, thereby improving the service life of the connecting part 20.

[0049] As for the arrangement of the inclined cable 60 and the second pile body 40, during the pouring process of the second pile body 40, the first end of the inclined cable 60 can be placed in the corresponding casting space, so that the first end of the inclined cable 60 and the second pile body 40 are integrally formed, thereby ensuring the connection effect.

[0050] In the structure of the connection portion 20 , in order to avoid stress concentration at the position of the reinforcing plate 230 , each vertex position of the reinforcing plate 230 is preferably designed as a chamfered structure to ensure its structural reinforcement effect on the support block 220 .

[0051] The embodiment of the utility model further provides a flexible photovoltaic system, which includes a main cable 50 and a stay cable 60, and the main cable 50 is locked and connected with the stay cable 60 at at least one end position through the end bracket structure provided by any of the above embodiments.
