DETAILED DESCRIPTION

[024] The technical solutions in the modalities of this request will be Petition 870240064649, dated 07 / 31 / 2024, p. 18 / 59 8 / 27 described clearly and completely below in conjunction with the drawings. Obviously, the embodiments described are only part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the art without creative work are within the scope of protection of this application.

[025] With reference to Figure 1, the present application provides a guyed tower 10. The guyed tower 10 includes a first tower body 11, a second tower body 12, a first guy wire assembly 13, a second guy wire assembly 14, and a third guy wire assembly 15. The first tower body 11 and the second tower body 12 are separated at the grounding. The first guy wire assembly 13 is fixedly connected between an upper end of the first tower body 11 and the grounding, is located on one side of the first tower body 11 away from the second tower body 12, and is configured to clamp the first tower body 11. The second guy wire assembly 14 is fixedly connected between an upper end of the second tower body 12 and the grounding, is located on one side of the second tower body 12 away from the first tower body 11, and is configured to clamp the second tower body 12.The third stay wire assembly 15 is securely connected between the upper end of the first tower body 11 and the upper end of the second tower body 12. In this way, the first tower body 11 and the second tower body 12 are stable. This prevents the first tower body 11 from being too tightly clamped by the first stay wire assembly 13, and therefore prevents it from deflecting to the side where the first stay wire assembly 13 is located. This also prevents the second tower body 12 from being too tightly clamped by the second stay wire assembly 14, and therefore prevents it from deflecting to the side where the second stay wire assembly 14 is located.

[026] The first tower body 11 and the second tower body 12 can be Petition 870240064649, dated 07 / 31 / 2024, page 19 / 59 9 / 27 a common transmission tower structure such as an iron lattice tower, a mast body, or a composite mast tower. Depending on the height of the mounting foundation, the foundations of the first tower body 11 and the second tower body 12 may be located at the same mounting height in a vertical direction, or at different mounting heights. A plurality of guyed towers 10 may be separated so that conductor wires are mounted to form a transmission line. In one embodiment, the tops of the first tower body 11 and the second tower body 12 are located at the same height. The top of the first tower body 11 and / or the top of the second tower body 12 are configured to secure the grounding wire to prevent the tower body or conductor wire from being struck by lightning and causing abnormal power interruptions.In one embodiment, the first tower body 11 and the second tower body 12 are arranged in a V shape, that is, the distance between the first tower body 11 and the second tower body 12 gradually decreases from the top to the ends of these fixedly connected to the grounding. Preferably, the angle formed between the first tower body 11 and the second tower body 12 is in the range of 5° to 15°, so that the guyed tower 10 has a small footprint and high structural stability.

[027] The first guy wire assembly 13 includes a guy wire and a connector device. One end of the guy wire is firmly connected to the upper end of the first tower body 11 via the connector device, and the other end of the guy wire is firmly connected to the ground via the connector device, so that the guy wire is firmly disposed between the first tower body 11 and the ground. One, two, or more guy wires may be provided according to the actual application scenario of the guyed tower 10, which is not limited to this. The second guy wire assembly 14 and the third guy wire assembly 15 have similar configurations to those of the first guy wire assembly. Petition 870240064649, dated 07 / 31 / 2024, page 20 / 59 10 / 27 stay wire 13, and will not be described in detail repeatedly. Provided the first stay wire assembly 13, the second stay wire assembly 14 and the third stay wire assembly 15, the first tower body 11 and the second tower body 12 are structurally stable and should not be easily deformed by force.

[028] Furthermore, in one embodiment, both an angle formed between the stay wire of the first stay wire assembly 13 and the first tower body 11, and an angle formed between the stay wire of the second stay wire assembly 14 and the second tower body 12 are in a range of 25° to 40°, so that the guyed tower 10 has a small footprint and high structural stability. Preferably, the stay wire of the first stay wire assembly 13 is fixedly connected to the top of the first tower body 11. The stay wire of the second stay wire assembly 14 is fixedly connected to the top of the second tower body 12. Two ends of the stay wire of the third stay wire assembly 15 are respectively fixedly connected to the top of the first tower body 11 and to the top of the second tower body 12.The stay wires are securely attached to the top of the tower bodies, which can increase the torque of the stay wires, so that under the same force conditions, the tower bodies as a whole are more stable.

[029] With reference to Figures 1 to 4, the guyed tower 10 additionally includes a crossarm mounting 100. The crossarm mounting 100 is fixedly connected between the first tower body 11 and the second tower body 12, and extends gradually upwards from its center to both sides. That is, one end of the crossarm mounting 100 is fixedly connected to the first tower body 11, and the other end of the entire crossarm mounting 100 is fixedly connected to the second tower body 12. The crossarm mounting 100 is V-shaped. The crossarm mounting 100 is configured to hold conductor wires 101. A direction from the first tower body 11 to the second tower body 12 in a horizontal direction is defined as a first direction F1, and a Petition 870240064649, dated 07 / 31 / 2024, page 21 / 59 11 / 27 A direction located in the same horizontal plane as the first direction F1 and perpendicular to the first direction F1 is defined as a second direction F2. The first tower body 11 and the second tower body 12 are separated in the first direction F1. Conductor wires 101 extend in the second direction F2 and are attached to the crossarm assembly 100. The second direction F2 is perpendicular to the first direction F1. The crossarm assembly 100 includes a plurality of insulating assemblies 110 connected in sequence. Two adjacent insulating assemblies 110 are fixedly connected to each other via a first connector assembly 200. A wire fastening cord 300 is arranged over the first connector assembly 200 to secure the conductor wires 101. Two ends of the crossarm assembly 100 are fixedly connected to the first tower body 11 and the second tower body 12 respectively via second connection assemblies 400.

[030] With reference to Figure 2, the insulating assembly 110 includes two separate insulators 111 that are parallel to each other. Each insulator 111 includes an insulating body, a sheath wrapped around the outer periphery of the insulating body, and two end fittings 1111 respectively sleeved onto two ends of the insulating body. The insulating body is an insulating body composite made of fiberglass impregnated with epoxy resin. The sheath may be made of high-temperature vulcanized silicone rubber, liquid silicone rubber, or room-temperature vulcanized silicone rubber, etc., which are not limited to these. The end fitting 1111 is configured to be fixedly connected to the first connector assembly 200 or to the second connector assembly 400.On the one hand, the 110 insulating mount made of composite material has a lightweight structure and is easy to process, and compared to conventional iron towers, the amount of steel used can be reduced, which is beneficial for environmental protection and can save costs on transportation, assembly, and maintenance. On the other hand, the 110 insulating mount... Petition 870240064649, dated 07 / 31 / 2024, page 22 / 59 12 / 27 has excellent external insulation performance, so safety hazards such as electrical discharge from pollution and electrical discharge from rain can be eliminated, the problem of phase-to-phase electrical discharge due to wind deflection can be solved, and safe operation can be ensured.

[031] The geometric axes of the two insulators 111 are parallel to each other. A plane formed by the geometric axes of the two insulators 111 is parallel to the second direction F2. By providing the insulating assembly 110 including two insulators 111, it is possible to withstand higher mechanical force and avoid failure of the entire crossarm assembly 100 due to the breakage of one of the insulators 111. In other embodiments, the insulating assembly may also include one insulator, or three or more separate insulators arranged in parallel, provided that the crossarm assembly meets the strength requirements for securing the conductor wire.

[032] With reference to Figure 1, the insulating assembly 110 having both ends connected to other insulating assemblies 110 is defined as a first insulating assembly 1110, and the insulating assembly 110 having one end connected to another insulating assembly 110 and the other end connected to the first tower body 11 or the second tower body 12 is defined as a second insulating assembly 1120.

[033] In one embodiment, the crossarm assembly 100 includes four insulating assemblies 110. Specifically, in the first direction F1, the crossarm assembly 100 includes a second insulating assembly 1120, a first insulating assembly 1110, another first insulating assembly 1110, and another second insulating assembly 1120 that are connected sequentially. A certain angle is formed between two adjacent insulating assemblies 110. First ends of the first two insulating assemblies 1110 are fixedly connected through the first connector assembly 200 to form a half-phase wire attachment point, and second ends of the first two insulating assemblies 1110 Petition 870240064649, dated 07 / 31 / 2024, page 23 / 59 13 / 27 are respectively fixedly connected to the first ends of the two second insulating assemblies 1120 through the first connection assemblies 200 respectively to form two secondary phase wire attachment points. Thus, three wire attachment points are formed. The wire attachment fitting cord 300 is provided in each of the three first connection assemblies 200 to secure three-phase conductor wires 101. The second ends of the two second insulating assemblies 1120 are respectively fixedly connected to the first tower body 11 and the second tower body 12 through the second connection assemblies 400.

[034] With reference to Figure 4, the first connector assembly 200 includes a first connection fitting 20. The first connection fitting 20 includes a connection plate 210 and a wire clamping plate 220. The connection plate 210 includes two flat plates 211 that are connected to each other. The flat plates 211 are rectangular plates, each of which has a first plate surface and a second plate surface that are arranged opposite each other, two first side surfaces that are connected to the first plate surface and the second plate surface in the direction of the length of the flat plates 211, and two second side surfaces that are connected to the first plate surface and the second plate surface in the direction of the width of the flat plates 211.The two flat plates 211 are connected to each other through one of their respective first lateral surfaces to form the connecting plate 210, and the plane where the connected surface is located is marked as plane P1. The connecting plate 210 is symmetrical with respect to plane P1, that is, the two flat plates 211 are symmetrical with respect to plane P1. The first plate surfaces of the two flat plates 211 are arranged to approach each other, so that a certain angle is formed between the two flat plates 211, and the connecting plate 210 is V-shaped as a whole. Thus, the two insulating assemblies 110. Petition 870240064649, dated 07 / 31 / 2024, page 24 / 59 14 / 27 connected to the two ends of the first connector assembly 200 are arranged at a certain angle. The first plate surfaces of the two flat plates 211 form the inner V-shaped plate surface of the connection plate 210, and the second plate surfaces of the two flat plates 211 form the outer V-shaped plate surface of the connection plate 210.

[035] Each flat plate 211 is provided with two first mounting holes 212. The two first mounting holes 212 are respectively arranged at two ends of the flat plate 211 in the direction of the length of the flat plate 211. The ends of the two adjacent insulating mounts 110 close to each other are mounted in the first mounting holes 212 respectively. Specifically, the end fittings 1111 at the ends of the two insulators 111 of each insulating assembly 110 are respectively connected to the first two mounting holes 212 at the two ends of the same plate 211, and thus connected to the two adjacent insulating assemblies 110 via the first connector assembly 200. Furthermore, each plate 211 is additionally provided with a first through hole 213 and a second through hole 214. With reference to Figure 3, the first through hole 213 is configured to be connected to a shielding ring 500.A first through hole of 213 or more may be provided, which is not limited herein. The second through hole 214 is used as a construction hole reserved for construction or maintenance, and a second through hole of 214 or more may be provided, which is not limited herein.

[036] The connection plate 210 is integrally formed by a stamping process, which ensures the overall structural strength of the first connection fitting 20. When the first connector assembly 200 connects two adjacent insulating assemblies 110, the inner V-shaped plate surface of the connection plate 210 is located on top, and the outer V-shaped plate surface of the plate Petition 870240064649, dated 07 / 31 / 2024, page 25 / 59 Connection plate 210 (15 / 27) is located at the bottom. Wire clamping plate 220 is placed on the V-shaped outer plate surface of connection plate 210. One end of wire clamping plate 220 is securely connected to the second plate surfaces of the two flat plates 211, and one plate surface of wire clamping plate 220 is perpendicular to the second plate surface of the flat plates 211. Wire clamping plate 220 is provided with a wire clamping hole 221. A wire clamping cord 300 is placed in the wire clamping hole 221 to secure the conductor wires 101. The overall structure and connection method of connection plate 210 are simple and easy to construct.

[037] Two first reinforcement plates 231 are provided on a side surface of the wire clamping plate 220. Each first reinforcement plate 231 is connected to both the wire clamping plate 220 and the connecting plate 210. The two first reinforcement plates 231 are respectively arranged on the second plate surfaces of the two flat plates 211 and extend in the direction of the length of the corresponding flat plate 211. The first reinforcement plates 231 are perpendicular to both the side surface of the wire clamping plate 220 and the second plate surface of the flat plates 211. A second reinforcement plate 232 is additionally connected between the two first reinforcement plates 231, so that the connection between the wire clamping plate 220 and the connecting plate 210 is more stable, and the total mechanical strength of the first connecting fitting 20 is ensured.A construction plate 233 is connected to a plate surface of the second reinforcement plate 232 distant from the wire fastening plate 220. The construction plate 233 is connected to both the second reinforcement plate 232 and the connection plate 210. The construction plate 233 is provided with a construction hole for construction or maintenance. The second reinforcement plate 232 is parallel to the wire fastening plate 220. The construction plate 233 is perpendicular to the second reinforcement plate 232, that is, the construction plate 233 is... Petition 870240064649, dated 07 / 31 / 2024, page 26 / 59 16 / 27 parallel to the first reinforcement plate 231. Furthermore, symmetrically, with the same structure, the first reinforcement plates 231, the second reinforcement plate 232, and the construction plate 233 are arranged on another side of the wire clamping plate 220. By arranging the reinforcement plates on both sides of the wire clamping plate 220 and connecting the wire clamping plate 220 and the flat plates 211 at the same time, the first connection fitting 20 has a symmetrical structure as a whole, ensuring that the overall structure of the first connection fitting 20 is stable and the overall force on the first connection fitting 20 is more reasonable.

[038] When the first connector assembly 200 is used to form a half-phase wire clamping point, with reference to Figure 6, the first connection fitting 20 has a symmetrical configuration around plane P1, that is, the connection plates 210, the wire clamping plates 220, the first reinforcement plates 231, the second reinforcement plates 232, and the construction plates 233 are all symmetrically arranged around plane P1, so that the crossarm assembly 100 is configured symmetrically around plane P1. Thus, the force on the crossarm assembly 100 is balanced after clamping the conductor wires 101, and the structure is stable. In this case, plane P1 is a vertical plane, and the construction plate 233 is arranged in a vertical direction to facilitate the construction of lifting equipment.

[039] When the first connector assembly 200 is used to form a secondary phase wire attachment point on one side, see Figure 7, the connection plate 210 of the first connector assembly 20 has a symmetrical configuration around plane P1. As the cross assembly 100 gradually extends upwards from the center to both sides, plane P1 needs to be arranged at a certain angle relative to the vertical plane so that one of the flat plates 211 of the connection plate 210 is arranged higher than one of the others. Petition 870240064649, dated 07 / 31 / 2024, page 27 / 59 17 / 27 flat plates 211, thus making the second insulating assembly 1120 higher than the first insulating assembly 1110. The first reinforcing plates 231 and the second reinforcing plates 232 still each have a symmetrical configuration around plane P1. The size of the wire clamping plate 220 adjacent to the second insulating assembly 1120 is larger than the size of the wire clamping plate 220 adjacent to the first insulating assembly 1110, which plays a role in reinforcing the mechanical strength. The construction plates 233 are further arranged in the vertical direction for easy construction of lifting equipment.

[040] The angle formed between two adjacent insulating assemblies 110 is designed according to the electrical insulation requirements in real engineering applications. The angle formed between the V-shaped inner plate surfaces of the connection plate 210 of each first connector assembly 200 in the crossarm assembly 100 may be equal or different, to adapt to different arrangements of the insulating assemblies 110.

[041] With reference to Figure 3, the wire clamping snap cord 300 in this embodiment is a six-bundle wire clamping snap cord 300, which is attached below the first connector assembly 200 by means of a connector rod. Six clamps (not shown) are arranged on the wire clamping snap cord 300 to secure the six-bundle conductor wire 101. The six-bundle wire clamping snap cord 300 may be a quadrilateral hollow plate. A T-shaped plate connected to one side of the hollow plate. Clamping points are respectively arranged at the four corners of the hollow plate and at two ends of the T-shaped plate in a transverse direction, so as to secure the six-strand conductor wire 101. The six-strand wire clamping fitting cord 300 may also be a hexagonal hollow plate, and clamping points are respectively arranged at the six corners of the hexagon.

[042] In other embodiments, the wire clamping snap rope may also have other structures, and other numbers of clamps may be provided on the wire clamping snap rope to secure conductor wires with different numbers grouped together, which is not limited here, so that the guyed tower may have a wider range of applications. With reference to Figure 8, in one application scenario, the 300 wire clamping snap rope is a 300 four-bundle wire clamping snap rope, which is specifically a plate with four clamping points, which can be connected to four clamps to secure a four-bundle conductor wire. The 300 wire clamping snap rope is connected to a wire clamping plate of the first connector assembly 200 through some adjustment plates.With reference to Figure 9, in another application scenario, the wire clamping yoke 300 is the three-bundle wire clamping yoke 300, which is specifically a T-shaped plate.

[043] With reference to Figure 3, the first connector assembly 200 additionally includes an extension member 240. The end fitting 1111 of the insulator 111 and the connection plate 210 are fixedly connected to each other through the extension member 240. The end fitting 1111 is a ring fitting, and two ends of the extension member 240 are also formed as ring fittings. One end of the extension member 240 is connected to the insulator assembly 110, specifically, fixedly connected to the end fitting 1111 through a U-shaped fitting, and the other end of the extension member 240 is fixedly connected to the connection plate 210 also through a U-shaped fitting. In other embodiments, such connections may also be made in other ways, which are not limited to these.The extension member 240 can extend the total length of the first connector assembly 200, and on the premise of ensuring that the electrical insulation between the multi-phase conductor wires meets the operating requirements of the guyed tower 10, the total length of the insulating assembly 110 can be reduced, saving the cost of the crossarm assembly 100.

[044] The first connector assembly 200 is additionally provided with a shielding ring 500. The shielding ring 500 includes an arc-shaped ring body. The arc-shaped ring body is securely connected to the first connector assembly 200 by means of a connector clamp (not shown). The arc-shaped ring body can be securely connected to the connection plate 210 or to the extension member 240, which is not limited herein. The shielding ring 500 has the function of balancing voltage, and can protect the first connector assembly 200, thus ensuring the service life of the first connector assembly 200.

[045] In one embodiment, the arc-shaped ring body of the 500 shielding ring is a semicircular ring body. Compared to the surfaces of Petition 870240064649, dated 07 / 31 / 2024, page 30 / 59 20 / 27 metal curves of the various components of the first connector assembly 200, the semicircular ring body has a very large radius of curvature and a smooth metal surface, and thus extreme electric field distortion will not be produced. Arranging the semicircular ring body over the first connector assembly 200 can well cover the prominent metal surface in the first connector assembly 200, so that the surrounding electric field regions are uniformly distributed and corona discharge does not occur. In addition, compared with the arc-shaped ring body with a central angle greater than 180°, the semicircular ring body can save the cost of the 500 shielding ring.

[046] The first connector assembly 200 of the present application has a configuration that meets the connection requirements of the insulator assemblies 110 on both sides and the fastening requirements of the wire fastening fitting 300, while also taking into account construction and assembly convenience for fastening the wires. Compared with node fittings of a conventional crossarm mounted on a self-supporting iron tower, the structure of the present application is simpler and lighter in weight.

In other embodiments, the crossarm assembly may also include other numbers of insulating assemblies, or a plurality of crossarm assemblies may be arranged at intervals in the vertical direction between the first tower body and the second tower body, which may be designed according to the requirements of the power transmission line, and which is not limited here.

[054] With reference to Figure 15, in another embodiment, the guyed tower 10 has a configuration similar to the structure mentioned above, except for the specific crossarm mounting structure 100. The crossarm mounting 100 is fixedly connected between the first tower body 11 and the second tower body 12, and gradually extends upwards from the center to both sides. The crossarm mounting 100 includes three insulating mounts 110. In the first direction F1, the crossarm mounting 100 includes a second insulating mount 1120, a first insulating mount 1110 and another second insulating mount 1120 which are connected sequentially. A certain angle is formed between two adjacent insulating mounts 110. The specific angle can be designed according to the actual application and will not be described in detail repeatedly.

[055] The first insulator assembly 1110 includes three insulators connected together, so that the first insulator assembly 1110 forms a triangular structure. The interconnected parts between the three insulators form three vertex ends of the first insulator assembly 1110. The first ends of the two second insulator assemblies 1120 are fixedly connected to two of the vertex ends of the first insulator assembly 1110 through the first connection assemblies 200 respectively, and the second ends of the two second insulator assemblies 1120 are fixedly connected to the first tower body 11 and the second tower body 12 through the second connection assemblies 400 respectively. The insulators have the same configurations as those described above, which will not be Petition 870240064649, dated 07 / 31 / 2024, page 35 / 59 25 / 27 repeatedly described again.

[056] The two vertex ends of the first isolating assembly 1110 that are fixedly connected to the second isolating assemblies 1120 are defined respectively as a first vertex end and a second vertex end, respectively, and another vertex end of the first isolating assembly 1110 is defined as a third vertex end. The third vertex end is located below the first vertex end and the second vertex end. In one embodiment, the straight line formed by connecting the first vertex end to the second vertex end is parallel to the horizontal plane. In other embodiments, a certain angle may be formed between the straight line formed by connecting the first vertex end to the second vertex end and the horizontal plane, which is not limited here.

[057] The first ends of two second insulating assemblies 1120 are fixedly connected to the first insulating assembly 1110 through the first connecting assemblies 200 respectively.

[058] The 110 insulating assembly may include one insulator, or it may include a plurality of separate insulators arranged parallel to each other, provided that the 100 crossarm assembly meets the strength requirements for securing the wires.
