Description

Technical Field

[0001] The present application relates to the field of a conductor fixing device for an iron tower, and in particular to a conductor fixing device for a galvanized iron tower and a galvanized iron tower. Background Art

[0002] Galvanized iron towers are widely used in the field of power transmission and are favored for their good corrosion resistance and structural stability. However, with the continuous development of power systems, the wear of conductors under external forces such as wind has gradually become an important factor affecting their stability and service life. How to improve the wind resistance of conductors and reduce their wear caused by external forces has become one of the technical problems that technicians in this field need to solve urgently.

[0003] In order to deal with the problem of damage caused by the shaking of the conductors under the action of wind, some technical solutions will set a rigid fixing seat at the fixing point of the conductor to directly limit the movement of the conductor; in addition, there are also technical solutions to set a wind shield or other shielding structure on the conductor fixing device to weaken the direct impact of wind on the conductor.

[0004] However, these traditional technologies have the following shortcomings: Although the fixed connection method can effectively limit the movement of the wire, it is easy to cause a hard collision between the wire and the fixing seat under the action of wind, causing the wire to wear more, and it is difficult to effectively extend the service life of the wire. To solve the above problems, technicians in this field need to find a fixing device with better buffering effect and can effectively reduce wire wear. Summary of the invention

[0013] Optionally, the main rod is hollow, and the connecting assembly includes:

[0014] A force dividing rod, the force dividing rod is located in the inner cavity of the main rod, and a movable gap is formed between the outer peripheral wall of the force dividing rod and the inner peripheral wall of the main rod;

[0015] A first universal ball, the first universal ball being fixedly connected to one end of the force component rod close to the top end of the main rod; and

[0016] A first ball seat, wherein the first ball seat is fixedly connected to the main rod, and the first universal ball is universally hinged to the first ball seat;

[0017] The mounting seat rotates relative to the main rod around a first axis.

[0018] By adopting the above technical solution, the main pole is hollow and includes a force component rod located in the inner cavity. The end of the force component rod close to the top of the main pole is universally hinged to the first ball seat through a first universal ball, so that the force component rod can rotate flexibly relative to the main pole, thereby enhancing the flexibility and adaptability of the connecting component and improving the stability of the cable fixing device in the face of changes in the external environment; the mounting seat is connected to the main pole by rotating around the first axis, which further enhances the flexibility of the mounting seat, allowing the mounting seat to rotate freely with changes in wind force, thereby reducing hard collisions between the wires and the mounting seat.

[0019] Optionally, there are a plurality of force component rods, the plurality of force component rods are spaced apart in the first direction, and two adjacent force component rods are universally hinged;

[0020] The mounting seat is connected to the force component rod away from the top end of the main rod.

[0021] By adopting the above technical solution, multiple force-dividing rods are distributed in sequence in the first direction, and two adjacent force-dividing rods are relatively rotated through the universal hinge assembly, so that the mounting seat can flexibly adjust its position with the shaking of the wire, reducing the hard collision between the wire and the mounting seat. The mounting seat is connected to the force-dividing rod far away from the top of the main rod, which further improves the stability and flexibility of the wire fixing device and effectively avoids the wear of the wire caused by wind force.

[0022] Optionally, a plurality of buffer components are further included, wherein the buffer component includes a second traction spring, one end of the second traction spring is connected to the force component rod, and the other end abuts against the inner wall of the main rod.

[0030] By adopting the above technical solution, the ball contacts the inner wall of the main rod, which can make the second traction spring slide more smoothly along the inner wall of the main rod, thereby improving the buffering effect of the buffer assembly on the collision between the force component rod and the main rod, thereby enhancing the stability and durability of the entire cable fixing device.

[0031] Optionally, a limiter assembly is further included, and the limiter assembly includes:

[0032] A lower stop ring coaxially fixedly connected to the inner wall of the main rod, and an upper stop ring coaxially fixedly connected to the outer peripheral wall of the force component rod, wherein the lower stop ring is located on a side of the upper stop ring close to the mounting seat;

[0036] By adopting the above technical solution, the third traction spring can change the total length in the first direction, thereby forming a support and buffering effect between the upper limit ring and the lower limit ring to prevent the force-dividing rod from excessively displacing in the main rod, and to prevent the force-dividing rod from hard collision with the main rod during external impact or shaking, thereby further improving the stability of the connecting assembly and the overall reliability of the cable fixing device.

[0037] Optionally, the opening of the threading hole is in an expanded hole shape.

[0038] By adopting the above technical solution, the opening of the threading hole is in an expanded hole shape, which can reduce the wear caused by the edge of the opening when the wire is blown by wind, thereby reducing the risk of the wire being broken.

DETAILED DESCRIPTION

[0054] The following is combined with Figure 1-Figure 6 This application is described in further detail.

[0055] The present application embodiment discloses a conductor fixing device for a galvanized iron tower. Figure 1 and Figure 2 The conductor fixing device of the galvanized iron tower comprises a main pole 1 having a top end 11 and a bottom end 12, a mounting seat 2 having a threading hole 21, and a connecting assembly 3 movably connected between the mounting seat 2 and the main pole 1. The main pole 1 is arranged parallel to the first direction. The material of the main pole 1 is silicone rubber, that is, an insulating material, so as to insulate the conductor 01 and the iron tower;

[0056] The wire threading hole 21 on the mounting seat 2 is used for passing the wire 01. The hole openings at both ends of the wire threading hole 21 are both expanded, and preferably have rounded corners. When the wire 01 is blown by wind, the rounded corners of the hole opening can reduce the possibility of the wire 01 being broken compared to the right-angled edges. In order to further reduce the wear of the wire 01, a flexible pad is fixedly connected to the inner wall of the wire threading hole 21.

[0057] Reference Figure 2 and Figure 3 The mounting seat 2 is located at the bottom end 12 of the main pole 1. The mounting seat 2 is connected to the connecting assembly 3 by rotating around the first axis. The first axis can be rotated to be parallel to the first direction. That is to say, the mounting seat 2 can be rotated relative to the main pole 1. When the wind blows the conductor 01 horizontally, the mounting seat 2 weakens the hard collision between the conductor 01 and the mounting seat 2 by its own rotation.

[0058] In order to further reduce hard collision, in some embodiments of the present application, a first traction spring 4 is provided between the mounting seat 2 and the main rod 1; one end of the first traction spring 4 is fixedly connected to the mounting seat 2, and the other end is fixedly connected to a sliding block 41, and the sliding block 41 is rotatably connected to the bottom end 12 of the main rod 1 around a second axis, and the second axis is parallel to the first direction. Specifically, the second axis coincides with the central axis of the main rod 1;

[0059] Specifically, a plurality of guide arc grooves 13 coaxial with the second axis are formed at the bottom end 12 of the main rod 1, and the plurality of guide arc grooves 13 are spaced apart around the rotation circumference of the sliding block 41. The sliding block 41 is adapted to be located in the guide arc groove 13 and can rotate around the second axis. In some embodiments of the present application, the guide arc groove 13 is T-shaped, and the sliding block 41 is T-shaped with the guide arc groove 13 to prevent the sliding block 41 from disengaging from the main rod 1 in the first direction. The end of the first traction spring 4 away from the mounting seat 2 is fixedly connected to the sliding block 41, and the inner walls at both ends of the guide arc groove 13 are used to limit the sliding range of the sliding block 41 around the second axis.

The first universal ball 32 is adaptively embedded in the first ball seat 33 and can rotate freely along the first ball seat 33. An activity gap 34 is formed between the inner circumferential wall of the main rod 1 and the outer circumferential wall of the force component rod 31 on a plane perpendicular to the first direction to provide an activity space for the force component rod 31 to rotate along the main rod 1; the mounting seat 2 is connected to the end of the main rod 1 away from the top end 11 of the main rod 1;

[0061] In some embodiments of the present application, a plurality of force-dividing rods 31 are provided, and the plurality of force-dividing rods 31 are sequentially distributed in the first direction. The force-dividing rod 31 close to the top end 11 of the main rod 1 is universally hinged with the main rod 1 through the first ball seat 33 and the first universal ball 32. The mounting seat 2 is rotatably connected to the force-dividing rod 31 away from the top end 11 of the main rod 1 around the first axis, and is located on a side of the force-dividing rod 31 away from the top end 11 of the main rod 1.

[0062] Two adjacent force component rods 31 are universally hinged at one end close to each other. Specifically, a universal hinge assembly 5 is provided between the two adjacent force component rods 31. The universal hinge assembly 5 includes a second ball seat 51 and a second universal ball 52. Among the ends of the two adjacent force component rods 31 close to each other, one end of the force component rod 31 is fixedly connected to the second ball seat 51, and the other end of the force component rod 31 is fixedly connected to the second universal ball 52. The second universal ball 52 is adaptively embedded in the second ball seat 51 and can rotate freely along the second ball seat 51, so that the two adjacent force component rods 31 can rotate relative to each other.

[0063] Reference Figure 4 In some embodiments of the present application, a plurality of buffer components 6 are further included, and the buffer component 6 includes a second traction spring 61, one end of the second traction spring 61 is fixedly connected to the force component rod 31, and the other end is pressed against the inner wall of the main rod 1, so that the second traction spring 61 forms a buffer for the collision between the force component rod 31 and the main rod 1; in some embodiments, a ball 62 can also be fixedly connected to one end of the second traction spring 61 close to the main rod 1, and the ball 62 is pressed against the inner wall of the main rod 1, so that the second traction spring 61 can slide along the inner wall of the main rod 1 more smoothly;

[0064] In the present disclosure, the buffer assembly 6 includes three second traction springs 61, which are respectively a first spring 601, a second spring 602 and a third spring 603, wherein the first spring 601 is inclined toward the top end 11 of the main rod 1, the second spring 602 is inclined toward the bottom end 12 of the main rod 1, and the third spring 603 is perpendicular to the first direction;

[0065] Each force component rod 31 has a plurality of buffer components 6 distributed around the rod, so as to provide buffering for the main rod 1 from multiple angles.

[0066] Reference Figure 4 and Figure 5 In some embodiments of the present application, a limit assembly 7 is further included, the limit assembly 7 includes a lower limit ring 71 coaxially fixedly connected to the inner wall of the main rod 1 and an upper limit ring 72 coaxially fixedly connected to the outer peripheral wall of the force component rod 31. In the first direction, the lower limit ring 71 is located on the side of the upper limit ring 72 close to the mounting seat 2, and a buffer gap 73 is formed between the upper limit ring 72 and the lower limit ring 71; in the orthographic projection parallel to the first direction, the projection surfaces of the upper limit ring 72 and the lower limit ring 71 have an overlapping portion. Therefore, if the second ball seat 51 and the second universal ball 52 are separated, the upper limit ring 72 will overlap the lower limit ring 71 to prevent the force component rod 31 from separating from the main rod 1 and falling off;

[0067] In addition, in some embodiments of the present application, the limit assembly 7 also includes a third traction spring 74, which is located in the buffer gap 73. Under the action of external force, the third traction spring 74 can change the total length in the first direction. One end of the third traction spring 74 is fixedly connected to the upper limit ring 72, and the other end is fixedly connected to the lower limit ring 71, so that the third traction spring 74 can support the upper limit ring 72 and the lower limit ring 71 while playing a buffering role between the upper limit ring 72 and the lower limit ring 71.

[0068] Reference Figure 4 and Figure 5 In order to facilitate the installation of other structures in the main rod 1, in some embodiments of the present application, the main rod 1 includes a plurality of segmented rods 14, and the plurality of segmented rods 14 are distributed in sequence in the first direction. The ends of two adjacent segmented rods 14 are threadedly adapted to be connected, and each segmented rod 14 is provided with a corresponding force component rod 31, and a buffer assembly 6 and a limit assembly 7 are provided between each force component rod 31 and the segmented rod 14, and the limit assembly 7 is located on the side of the buffer assembly 6 away from the top end 11 of the main rod 1.

[0069] The implementation principle of a wire fixing device for a galvanized iron tower in an embodiment of the present application is as follows: during installation, the wire 01 is first passed through the wire threading hole 21 and then installed on the mounting seat 2, and then the main pole 1 is fixedly connected to the iron tower, and the mounting seat 2 can be installed on the iron tower; when the wind blows, the wire 01 will be blown and shaken by the wind, and as the wire 01 shakes, the segmented rod 14 will shake inside the main pole 1. During this process, the buffer assembly 6, the first traction spring 4, and the third traction spring 74 will all buffer the connecting assembly 3 and the mounting seat 2. Therefore, the wire fixing device in the present application can buffer the shaking of the wire 01, prevent the wire 01 from being broken due to the hard impact of the wind, and can increase the service life of the wire 01 and reduce the number of times the wire 01 is replaced and repaired.

[0070] The present application also discloses a galvanized iron tower. Figure 6 The galvanized iron tower includes the aforementioned wire fixing device and also includes a tower body 8 with a cross arm 81. Specifically, the main pole 1 in the wire fixing device is fixedly connected to the cross arm 81 of the tower body 8 by screws or clamps. In the present disclosure, the main pole 1 is fixedly connected to the cross arm 81 of the tower body 8 by screws.

[0071] The implementation principle of a galvanized iron tower in an embodiment of the present application is as follows: since a wire fixing device is installed on the tower body 8, when the wire 01 is attacked by wind, the connecting component 3 in the main pole 1 cooperates with the buffer component 6 to buffer the mounting seat 2. Under the premise that the mounting seat 2 can shake, the wire 01 can be reduced from being broken.

[0072] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
