Description

Technical Field

[0001] The present application relates to the technical field of steel strand fixing, and in particular to a steel strand fixing device for a central column. Background Art

[0002] Solar photovoltaic power generation uses the principle of photovoltaics to directly convert solar energy into electrical energy through photovoltaic panels. At present, the installation method of photovoltaic panels is: by pulling two steel strands between two neutral columns, and then installing the photovoltaic panels on the two steel strands. This installation structure is a flexible installation structure.

[0003] At present, in the flexible installation structure, U-bolts are used to fix the steel strands on the center column. After the steel strands pass through the through holes of the U-bolts, the staff passes the screws at both ends of the U-bolts through the buffer plate and the center column, and then uses bolts to fix the U-bolts with the steel strands mounted on them to the center column. There is point contact between the steel strands and the U-bolts installed using the above-mentioned flexible installation structure. When the span between the two center columns is large and the weight of the photovoltaic panels on one side is large, the steel strands on both sides are unevenly stressed and prone to sliding. In addition, in an environment with strong winds, if the photovoltaic panels shake, friction will occur between the steel ropes and the U-bolts, causing structural damage and thus affecting the service life.

[0004] Therefore, there is an urgent need for a stable device for fixing the steel strand to the center column. Utility Model Content

The second fastener is fixedly connected to the support member through a seventh surface of the second fastener opposite to the sixth surface. A first number of second connecting columns are respectively provided on both sides of the support member on the bottom plate, each second connecting column is provided with a second threaded through hole, and the first pressure steel rope plate is bolted to at least two second connecting columns of the second pressure steel rope plate through at least two first connecting columns to tighten the steel strand between the first groove and the second groove.

[0012] In a feasible design, a portion of the seventh side wall of each first connecting column is embedded in the first fixing plate.

[0013] In a feasible design, a portion of the eighth side wall of each second connecting column is embedded in the second fixing plate and the supporting member.

[0030] like Figure 1 As shown, the present application provides a central column steel strand fixing device, comprising a first steel rope pressing plate 1 and a second steel rope pressing plate 2.

[0033] Combine the following Figure 4 and Figure 5 Introducing the second pressed steel rope plate 2:

[0034] The second pressure rope plate 2 includes a support seat 21, a second fastener 22 and at least two second connecting columns 23. A raised support member 212 is provided in the middle of the bottom plate 211 of the support seat 21. Through holes 2111 are provided on the bottom plate 211 at both sides of the support member 212. A second fastener 22 is provided on the support member 212. The second fastener 22 includes a second fixed plate 221 and two second curved plates 222. The two ends of the second fixed plate 221 are respectively fixedly connected to the second curved plates 222. The fifth side wall 2221 and the sixth side wall opposite to each other in the second curved plate 222 are arranged in a fan shape. The fourth surface 2222 of the second curved plate 222 adjacent to the fifth side wall 2221 and the sixth side wall is an arc surface. The fifth surface 2211 of the second fixed plate 221 and the fourth surface 2211 of the two second curved plates 222 are arranged in a fan shape. The surface 2222 constitutes the sixth surface 223 of the second fastener 22, the fifth surface 2211 is a plane, the sixth surface 223 of the second fastener 22 is provided with a second groove 2231, and second concave notches 2232 are provided at both ends of the second groove 2231. The second fastener 22 is fixedly connected to the support member 212 through the seventh surface of the second fastener 22 opposite to the sixth surface 223, and a first number of second connecting columns 23 are respectively provided on both sides of the support member 212 on the bottom plate 211, and each second connecting column 23 is provided with a second threaded through hole 231. The first compression steel rope plate 1 is bolted to at least two second connecting columns 23 of the second compression steel rope plate 2 through at least two first connecting columns 12, so as to tighten the steel strand 3 located between the first groove 131 and the second groove 2231.

[0035] The value of the first number can be set according to actual needs, for example, the value of the first number is 1 or 2, that is, the total number of the first connecting pillars 12 is 2 or 4. If the total number of the first connecting pillars 12 is 4, the spacing between the first connecting pillars 12 on the same side can be set according to actual needs, and this application does not limit this.

[0036] It should be understood that through Figure 4 It can be seen that the seventh surface opposite to the sixth surface 223 is integrated with the support member 212, so the seventh surface is not shown in the drawings. It can also be understood that the shape of the seventh surface is not limited in this application.

[0037] The number of the second connecting columns 23 is the same as the number of the first connecting columns 12, and the position and size of each second connecting column 23 respectively correspond to the position and size of the first connecting column 12 that needs to be bolted, so that the first compression steel rope plate 1 is bolted to at least two second connecting columns 23 of the second compression steel rope plate 2 through at least two first connecting columns 12.

[0038] The number of through holes 2111 can be set according to actual needs. For example, the number of through holes 2111 is 2 or 4.

[0039] For example, the central column steel strand fixing device provided in the present application is processed by casting. Figure 2 It can be seen that the first fixing plate 111 and the two first arc-shaped plates 112 are integrated into one body after casting, thereby forming the first fastener 11. Figure 4 It can be seen that the second fixing plate 221 and the two second arc-shaped plates 222 are integrated into one body after being cast, thereby forming the second fastener 22 .

[0040] For example, if the through hole 2111 of the second compression steel rope plate 2 has no thread, a nail or the like can be passed through the through hole 2111 and the center column 4 to fix the bottom plate 211 on the center column 4. If the through hole 2111 of the second compression steel rope plate 2 has a thread, a bolt can be passed through the through hole 2111 and the center column 4 to fix the bottom plate 211 on the center column 4. The application scenario of fixing the center column 4 steel strand 3 fixing device on the center column 4 through the bottom plate is as follows: Figure 6 or Figure 7 shown.

[0041] Exemplarily, the curvature of the first surface 1122 is the same as the curvature of the fourth surface 2222 .

[0042] Exemplarily, the first connecting pillar 12 and the second connecting pillar 23 are cylindrical.

[0043] In the above embodiment of the present application, after the bottom plate 211 of the second compression steel rope plate 2 is fixed to the middle column 4 through the through hole 2111, the steel strand 3 is placed in the second groove 2231 of the second compression steel rope plate 2. Then, the first compression steel rope plate 1 and the second compression steel rope plate 2 are connected and fixed by bolts through the first connecting column 12 and the second connecting column 23, and the first compression steel rope plate 1 is placed with the first groove 1131 of the first compression steel rope plate 1 facing the direction of the steel strand 3. A through hole is formed between the first groove 1131 of the first compression steel rope plate 1 and the second groove 2231 of the second compression steel rope plate 2, so that the steel strand 3 can pass through the through hole, so that the steel strand 3 is fixed to the middle column 4. Since the steel strand 3 and the through hole formed by the first groove 1131 and the second groove 2231 are in surface contact, compared with the current solution of fixing the steel strand 3 with a U-bolt, in which the steel strand 3 and the U-bolt are in point contact, resulting in an unstable fixing effect of the steel strand 3, the contact area between the steel strand 3 and the first fastener 11 and the second fastener 22 in the present application is greatly improved, thereby being able to enhance the effect of the first pressing steel rope plate 1 and the second pressing steel rope plate 2 in tightening the steel strand 3. This further improves the stability of the device in fixing the steel strand 3, and avoids the problem of damage to the device due to the sliding of the steel strand 3 between the through holes. In addition, since the fixing effect of the device on the steel strand 3 is improved, it can also be used to fix the steel strand 3 between two large-span center columns 4.

[0044] Furthermore, if Figure 6 As shown, the steel strand 3 is affected by its own weight and the weight of the load, and will bend downward when passing through the two ends of the through hole formed by the first groove 1131 and the second groove 2231. In order to avoid the problem that the pressure per unit area at the edges of the two ends of the second groove 2231 is large due to the line contact between the bent portion and the corresponding edges at the two ends of the second groove 2231, it is easy to damage the service life of the device and increase the wear of the steel strand 3. The present application sets the fourth surface 2222 as an arc surface, so that the part of the second groove 2231 located at the second arc plate 222 is arc-shaped, and then the bending part of the steel strand 3 at the two ends of the second groove 2231 The exit and the arc groove are more fitted, the contact area is increased, and the pressure per unit area at the edges of the two ends of the second groove 2231 is reduced, which can reduce damage to the device. Moreover, the second concave notch 2232 can prevent the bent parts of the steel strand 3 at the two end exits of the second groove 2231 from contacting the corresponding edges at the two ends of the second groove 2231, thereby reducing the wear on the steel strand 3 and improving the compressive resistance of the steel strand 3 to its own weight and the weight of the load.

[0045] In addition, if Figure 7 As shown, when the middle column 4 is located at a lower terrain, and the middle columns on both sides are located at a higher terrain than the middle column 4, after the steel strand 3 is placed in the second groove 2231 of the second steel rope pressing plate 2, due to the high position of the steel strand 3 on the middle columns 4 on both sides, an upward pulling force is generated on the steel strand 3 on the middle column 4, so that the portion of the steel strand 3 fixed on the middle column 4 will bend upward. In order to avoid the problem that the pressure per unit area at the edges at both ends of the first groove 1131 is large due to the line contact between the bent portion and the corresponding edges at both ends of the first groove 1131, which is easy to damage the service life of the device and increase the wear of the steel strand 3. The present application sets the first surface 1122 as an arc surface, so that the portion of the first groove 1131 located at the first arc plate 112 is arc-shaped, and then the bending portion of the steel strand 3 at the exit of the two ends of the first groove 1131 increases the fit with the arc groove, the contact area increases, and the pressure per unit area at the edges at both ends of the first groove 1131 is reduced, which can reduce the damage to the device. Moreover, the first concave notch 1132 can prevent the bent parts of the steel strand 3 at the two end exits of the first groove 1131 from contacting the corresponding edges at the two ends of the first groove 1131, thereby reducing the wear on the steel strand 3 and improving the pull-out resistance of the steel strand 3 to upward pulling force.

[0046] It can be seen that in order to make the device have both anti-compression and anti-pulling effects, the present application sets the two ends of the through hole formed between the first groove 1131 and the second groove 2231 to a "trumpet-mouth" type, that is, the arc-shaped parts at both ends of the first groove 1131 extend upward (away from the ground) along the outlet, and the arc-shaped parts at both ends of the second groove 2231 extend downward (toward the ground) along the outlet.

[0047] It should be noted that, since the second surface 1111 is a plane, the portion of the first groove 1131 located on the first fixed plate 111 has no curvature, and this portion is a straight groove. And since the fifth surface 2211 is a plane, the portion of the second groove 2231 located on the second fixed plate 221 has no curvature, and this portion is a straight groove. Therefore, when the first compression steel rope plate 1 and the second compression steel rope plate 2 are fixedly connected, the portion of the first groove 1131 located on the first fixed plate 111 and the portion of the second groove 2231 located on the second fixed plate 221 can form a straight through hole, which is conducive to enhancing the fixing effect of the steel strand 3 passing through the straight through hole.

[0048] In a feasible design, a second number of protrusions 1133 (ie, first protrusions) are disposed in the first groove 1131 .

[0049] The second number is set according to actual needs, and this application does not limit this. Figure 3 As shown, the value of the second number is 8.

[0050] The shape of the first protrusion 1133 is set according to actual needs, and the present application does not limit this. For example, the shape of the first protrusion 1133 can be a rectangular parallelepiped.

[0051] For example, Figure 3 As shown, every two first protrusions 1133 form a right-side-up or a reverse-side-up shape and are distributed in the first groove 1131 to form an anti-slip step.

[0052] In this example, a first protrusion 1133 is provided in the first groove 1131, which can increase the friction between the steel strand 3 and the first groove 1131, and improve the stability of the steel strand 3 between the first pressure steel rope plate 1 and the second pressure steel rope plate 2, thereby improving the fixing effect of the device on the steel strand 3.

[0053] In a feasible design, a second number of protrusions 2233 (ie, second protrusions) are disposed in the second groove 2231 .

[0054] The implementation of the second protrusion 2233 refers to the description and Figure 4 The second pressing steel rope plate 2 shown is not described in detail here.

[0055] In this example, a second protrusion 2233 is provided in the second groove 2231, which can increase the friction between the steel strand 3 and the second groove 2231, and improve the stability of the steel strand 3 between the first pressure steel rope plate 1 and the second pressure steel rope plate 2, thereby improving the fixing effect of the device on the steel strand 3.

[0056] In a feasible design, one end of the first connecting column 12 facing the second pressure rope plate 2 extends out of the third surface 113 of the first fastener 11 .

[0057] If the end of the first connecting column 12 facing the second pressing steel rope plate 2 is flush with the third surface 113, then the first fixing plate 111 and the second fixing plate 221 are completely fitted, resulting in a fixed size of the through hole between the two, and the size of the applicable steel strand 3 is also fixed. Therefore, the present application designs the end of the first connecting column 12 facing the second pressing steel rope plate 2 to extend out of the third surface 113, so that when the first pressing steel rope plate 1 and the second pressing steel rope plate 2 are assembled using bolts, the portion of the first connecting column 12 extending out of the third surface 113 can leave a gap between the first pressing steel rope plate 1 and the second pressing steel rope plate 2, which can not only strengthen the tightening effect on the steel strand 3, but also be applicable to steel strands 3 of more sizes.

[0058] In one possible design, Figure 2 As shown, a portion of the seventh side wall 122 of each first connecting column 12 is embedded in the first fixing plate 111, which can increase the area of ​​the connecting portion between the first connecting column 12 and the first fixing plate 111 and strengthen the connection between the two. In addition, the material of the first fixing plate 111 is saved.

[0059] In one possible design, Figure 4 As shown, a portion of the eighth side wall 232 of each second connecting column 23 is embedded in the second fixing plate 221 and the support member 212, which can increase the area of ​​the connection portion between the second connecting column 23 and the second fixing plate 221 and the support member 212, and strengthen the connection between the second connecting column 23 and the second fixing plate 221 and the support member 212. In addition, the material of the second fixing plate 221 and the support member 212 is saved.

[0060] In one possible design, Figure 1 As shown, in order to save materials of the bottom plate 211 and the support member 212 , the support member 212 of the support seat 21 is provided with a groove in the direction toward the bottom plate 211 , that is, the inside of the support member 212 is hollow.
