DETAILED DESCRIPTION

[0034] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings, but these embodiments do not limit the present invention. Structural, methodological, or functional changes made by ordinary technicians in the field based on these embodiments are all included in the protection scope of the present invention.

[0035] like Figure 1 As shown, an embodiment of the present application provides a steel strand anchoring component 100 of a photovoltaic support, and the steel strand anchoring component 100 of the photovoltaic support includes: a column 11, a fixed support 12, a sliding support 13 and an anchor 14.

[0036] The column 11 is provided with a through hole for the steel strand 21 to pass through;

[0037] The fixed support 12 is connected to the column 11, and the fixed support 12 includes an arc-shaped support plate 121. A sliding gap is provided in the fixed support 12, and the sliding gap is used for the steel strand 21 to penetrate;

[0038] The sliding support 13 includes an arc-shaped sliding end surface, which is concentric with the support plate 121 and has the same diameter, and is used to abut against the support plate 121. The sliding support 13 is provided with a through hole, and the through hole is used for the steel strand 21 to penetrate;

[0039] The anchor 14 is used to be fixedly connected to one end of the steel strand 21 passing through the sliding support 13. The anchor 14 abuts against the sliding support 13. The assembly formed by the anchor 14 and the sliding support 13 can slide along the sliding gap on the fixed support 12 and can be locked with the fixed support 12 under the prestressed action of the steel strand 21.

[0040] Specifically, according to the steel strand anchoring component 100 of the photovoltaic support provided in the embodiment of the present application, the fixed support 12 is provided with a sliding gap, and the steel strand 21 can slide along the sliding gap. The sliding end surface and the support plate 121 are both arc-shaped and concentric with the same diameter, so that the sliding support 13 and the fixed support 12 can be completely fitted, and the sliding support 13 can slide along the sliding gap. When the steel strand anchoring component 100 of the photovoltaic support is installed, the steel strand 21 passes through the column 11, the fixed support 12 and the sliding support 13 in sequence and is fixedly connected to the anchor 14. For ease of explanation, in the embodiment of the present application, the combination of the anchor 14 and the sliding support 13 is referred to as an assembly, and the assembly can slide along the sliding gap on the support plate 121, so that the installation angle of the steel strand 21 can be arbitrarily adjusted according to the terrain, so that the axial direction of the anchor 14 is consistent with the axial direction of the steel strand 21, which can avoid the occurrence of folding angles in the steel strand 21 and extend the service life of the steel strand 21. Furthermore, under the axial force of the steel strand 21 , a huge static friction force exists on the contact surface between the sliding support 13 and the fixed support 12 , so that the installation position of the assembly on the fixed support 12 is fixed.

[0041] like Figure 2 As shown, as an optional implementation method, in the steel strand anchoring member 100 of the photovoltaic support provided in the embodiment of the present application, the column 11 includes two parallel side panels and a connecting plate 113 connecting the side panels. For ease of understanding, the column 11 can be simply understood as an approximate "I" structure, and the connection position between the connecting plate 113 and the side panel can be close to the center line of the side panel, or close to the left or right side of the side panel. In the embodiment of the present application, the connection position between the connecting plate 113 and the side panel is close to the center line of the side panel. Preferably, the two side panels are symmetrical about the connecting plate. In this way, the stability of the flange of the column 11 can be improved.

[0042] The fixed support 12 is connected to one side plate of the column 11. For the sake of convenience, the side plate connected to the fixed support 12 is defined as the first side plate 111, and the other side plate of the column 11 is defined as the second side plate 112. Figure 1The front-to-back, left-to-right, and up-to-down directions are shown with the direction from the second side panel 112 to the first side panel 111 as the forward direction, the extending direction of the side panel as the up-to-down direction, and the front-to-back, left-to-right, and up-to-down directions being perpendicular to each other.

[0043] Through holes are provided on the first side plate 111 and the second side plate 112, and the through holes on the two side plates are located on the same side of the connecting plate 113, so that the steel strand 21 can pass through the through holes on the second side plate 112 and the first side plate 111 in sequence. Furthermore, in the embodiment of the present application, the through holes on the first side plate 111 and the second side plate 112 are both oblong holes, and the length direction of the oblong holes is the vertical direction. It is easy to understand that when the steel strand anchoring component 100 of the photovoltaic support is installed, the column 11 is vertically arranged, and at this time the length direction of the oblong hole of the side plate is parallel to the vertical direction, and the extension direction of the sliding gap on the fixed support 12 is consistent with the length direction of the oblong hole. In this way, the steel strand 21 will not be restricted by the column and can slide along the sliding gap, which can increase the adjustment range of the installation angle of the steel strand.

[0044] Furthermore, the through holes on the two side plates are arranged close to the connecting plate 113. In this way, the torsion on the column 11 can be reduced and the stability of the flange of the column 11 can be improved.

[0045] like Figure 2 As shown, as an optional implementation, the length of the through hole on the first side plate 111 is less than the length of the through hole on the second side plate 112. In this way, it can ensure that the adjustment range of the installation angle of the steel strand 21 is large enough, and the milling amount of the first side plate 111 can be reduced, thereby avoiding the strength reduction of the first side plate 111, thereby ensuring the bearing capacity of the column 11.

[0046] The lengths of the through holes of the first side plate 111 and the second side plate 112 need to satisfy the following relationship, so as to ensure that the portion of the steel strand 21 passing through the column 11 will not be restricted by the through holes. The relationship is as follows: i=1,2.

[0047] Where θ represents the angle range of the assembly allowed to slide. When i = 1, L i represents the length of the through hole on the first side plate 111, h i represents the distance from the center of the assembly sliding track to the first side plate 111. When i=2, L i represents the length of the through hole on the second side plate 112, h i It represents the distance from the center of the sliding track of the assembly to the second side plate 112. It is easy to understand that the sliding support 13 is in contact with the surface of the fixed support 12, so the center of the sliding track of the assembly coincides with the axis point of the fixed support 12.

[0048] like Figure 3As shown, the fixed support 12 includes two fixed support side plates 122 and an arc-shaped support plate 121. For ease of understanding, the structure of the fixed support 12 can be regarded as a truncated cylinder formed by cutting a cylinder along a high line, and the axis point of the fixed support 12 is the axis point of the cylinder. The upper and lower end surfaces of the truncated cylinder correspond to the two fixed support side plates 122 respectively, and the side surface of the truncated cylinder corresponds to the arc-shaped support plate 121. The support plate 121 is provided with a long arc hole 101. Combined with Figure 2 and Figure 3 The long arc hole 101 and the through hole on the first side plate 111 form a sliding gap. The sliding support 13 abuts against the support plate 121, so that the assembly formed by the anchor 14 and the sliding support 13 can slide on the fixed support 12 along the sliding gap.

[0049] As an optional implementation, Figure 4 As shown, the axis center point of the fixed support 12 is located at the front side of the first side plate 111 .

[0050] like Figure 5 As shown, as another optional implementation, the axis point of the fixed support 12 is located between the first side plate 111 and the second side plate 112 .

[0051] According to the relationship satisfied by the length of the through hole of the side panel, it is easy to understand that the axis point of the fixed support 12 is set close to the through hole of the first side panel 111. At this time, in this way, the distance between the axis point of the fixed support 12 and the first side panel 111 is shortened, and the requirement for the length of the through hole on the first side panel 111 can be reduced.

[0052] Further, such as Figure 6 As shown, as an optional implementation, the two fixed support side plates 122 are semicircular, at this time, the distance between the axis point of the fixed support 12 and the first side plate 111 is the shortest. In this embodiment, the length of the through hole of the first side plate 111 is greater than the wire diameter of the steel strand 21 to meet the requirements. In addition, in this embodiment, the assembly can allow the largest sliding range, which can better meet the requirements of adjusting the installation angle of the steel strand 21 according to the terrain.

[0053] Furthermore, the center of the long arc hole 101 on the support plate 121 coincides with the center of the through hole on the first side plate 111. In this way, it can be ensured that the portion of the steel strand 21 from the through hole on the first side plate 111 to the long arc hole 101 of the fixed support 12 will not be bent.

[0054] It is easy to understand that as another optional implementation method, Figure 7 As shown, the axis point of the fixed support 12 can also be located behind the second side plate 112. In this embodiment, the length of the through hole on the first side plate 111 needs to be greater than or equal to the length of the through hole on the second side plate 112.

[0055] like Figure 8 As shown, the side plates on the left and right sides of the fixed support 12 are located on both sides of the connecting plate 113. In this way, the torsion borne by the first side plate 111 can be balanced.

[0056] Furthermore, the left and right side plates of the fixed support 12 are axially symmetrical with respect to the connecting plate 113 . In this way, the torque on the column 11 can be reduced as much as possible, thereby improving the stability of the column 11 .

[0057] For ease of explanation, in the embodiment of the present application, a side of the first side plate 111 connected to the connecting plate 113 is defined as an inner side surface, and a side of the first side plate 111 facing away from the connecting plate 113 is defined as an outer side surface.

[0058] As an optional implementation, the fixed support 12 is fixedly arranged on the outer side of the first side plate 111. The fixed support 12 is formed integrally with the column 11. For example, the fixed support 12 is welded integrally with the column 11 before leaving the factory, and no on-site welding is required. In this way, the construction is much cheaper, the process level can be guaranteed, and the anti-corrosion layer of the steel component can be protected.

[0059] As an optional implementation, Fig. 9 As shown, at least one stiffening plate 114 is fixedly arranged on the inner side surface of the first side plate 111. Specifically, in the embodiment of the present application, two stiffening plates 114 are arranged on the left and right sides of the connecting plate 113, and one end of each stiffening plate 114 is fixedly connected to the inner side surface connected to the first side plate 111, and the other end of the stiffening plate 114 is fixedly connected to the connecting plate 113. In this way, the stability of the flange of the column 11 can be further improved, thereby improving the bearing capacity of the column 11. In addition, the stiffening plate 114 can also be integrally formed with the column 11 to ensure the process level, avoid damage to the anti-corrosion layer of the steel component caused by on-site welding, and protect the anti-corrosion layer of the steel component.

[0060] like Fig.10 As shown, as an optional implementation, an anchor lug plate 115 is further provided on the column 11, and the anchor lug plate 115 is used to connect the foundation to resist the pulling force of the steel strand 21 on the column 11. Specifically, the anchor lug plate 115 can be connected to the foundation through fixing parts such as steel bars and the steel strand 21, so that the component force of the steel strand 21 in the front and rear directions can be balanced, thereby improving the bearing capacity of the column 11.

[0061] like Fig.11 , which shows a schematic diagram of a sliding support 13 provided in an embodiment of the present application, wherein the sliding support 13 includes a sliding end surface that can be fitted with the support plate 121. In addition, a through hole is provided at the center of the sliding support 13, and the through hole is used for the steel strand 21 to penetrate.

[0062] As an optional implementation, the end face of the anchor 14 abutting against the sliding support 13 is defined as the first end face, and the end face away from the sliding support 13 is defined as the second end face, and the area of ​​the first end face is greater than the area of ​​the second end face. Fig.12 As shown, the anchor 14 is approximately a hat-shaped structure, and the portion of the anchor 14 close to the sliding support 13 extends radially, thereby increasing the contact area between the anchor 14 and the sliding support 13, reducing the pressure between the anchor 14 and the sliding support 13, and preventing the anchor 14 from being damaged.
