Description

Technical Field

[0001] This utility model relates to the field of tower reinforcement technology, specifically a reinforcement structure for power transmission line towers. Background Technology

[0002] Transmission line towers, as key supporting structures in power transmission systems, are widely used in high-voltage and ultra-high-voltage transmission networks, undertaking the core functions of conductor suspension, insulator fixation, and load transfer. Towers are typically constructed using angle steel or steel pipes connected by bolts to form a lattice-type tower structure. They are characterized by their height, large span, and long-term exposure to the outdoor environment. Their design must comprehensively consider dynamic loads such as wind loads, icing, earthquakes, and foundation settlement to ensure stability under extreme weather conditions.

[0003] Traditional iron towers rely on foundation anchoring and tower rigidity to resist wind loads. Under strong winds (such as typhoons and storms) or earthquakes, the tower is prone to lateral displacement or even overturning. Especially in tall iron towers, the high center of gravity leads to an increased overturning moment, and insufficient foundation pull-out resistance can easily cause overall instability. Utility Model Content

[0004] The purpose of this utility model is to provide a reinforcement structure for transmission line towers to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution;

[0006] A reinforcement structure for a transmission line tower includes a tower body, tensile concrete piers, and a mass block. Four upper tension rings are welded at equal intervals from top to bottom at the four corners of the tower body. Four tensile concrete piers are arranged around the base of the tower body. Four lower tension rings are embedded side-by-side on the tensile concrete piers. A first steel wire rope is installed between the four lower tension rings and the corresponding four upper tension rings on the tower body. The two ends of the first steel wire rope are fixed to the upper and lower tension rings, respectively. A cross beam is welded in the middle of the tower body, and lifting holes are opened on the cross beam. A second steel wire rope is attached to the lifting holes, and the bottom end of the second steel wire rope is connected to a pre-embedded lifting ring fixed above the mass block.

[0007] As a further embodiment of this utility model: a fence is set on the ground directly below the mass block.

[0008] As a further improvement of this utility model: the tensile concrete pier is pre-embedded with anchor rods, the top of the anchor rods is fixed to the pull ring, and the anchor rod part is inserted into the ground.

[0009] As a further improvement of this utility model, the four tensile concrete piers are distributed in a radiating pattern around the base of the iron tower body.

[0010] As a further improvement of this utility model, warning signs are provided on all four outer sides of the enclosure.

[0011] As a further improvement of this utility model, the anchor rod is provided with barbs.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model sets up four tensile concrete piers distributed in a radiating pattern around the base of the iron tower. The upper tension ring of the tower body and the lower tension ring of the piers are connected by a first steel wire rope to form a multi-directional inclined tension constraint network. When the iron tower is subjected to horizontal loads such as strong winds or earthquakes, the inclined ropes quickly tighten, dispersing the tension of the tower body to the concrete piers and the foundation, reducing the bending stress of the tower body, and preventing the tower body from tilting or twisting. At the same time, the radiating layout of the concrete piers optimizes the force transmission path, thereby improving the overturning safety factor of the iron tower. It is particularly suitable for soft foundations or typhoon-prone areas, and extends the service life of the iron tower.

[0014] 2. In this utility model, the mass block is suspended below the tower body by a second steel wire rope. The downward movement of the mass block causes the total center of gravity of the tower body to shift downward, reducing the overturning moment (overturning moment = total weight × center of gravity offset height), and improving the stability under horizontal loads such as wind and earthquake resistance.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 and Figure 3 In this embodiment of the utility model, a reinforcement structure for a transmission line tower includes a tower body 1, tensile concrete piers 4, and mass blocks 11. Four upper pull rings 2 are welded at equal intervals from top to bottom at the four corners of the tower body 1. Four tensile concrete piers 4 are arranged around the base of the tower body 1. Four lower pull rings 5 ​​are pre-embedded side-by-side on the tensile concrete piers 4. A first steel wire rope 3 is arranged between the four lower pull rings 5 ​​and the corresponding four upper pull rings 2 on the tower body. The two ends of the first steel wire rope 3 are respectively fixed to the upper pull rings 2 and the lower pull rings 5. Pre-embedded components are embedded within the tensile concrete piers 4. Anchor rods 6 are provided, with the top of the anchor rods 6 fixed to the pull rings 5. The anchor rods 6 are partially inserted into the ground. Anchor rods 6 are pre-embedded in the tensile concrete piers 4 and inserted into the ground to enhance the mechanical interlocking between the pier and the foundation, improve the pull-out resistance, prevent the concrete pier from shifting under extreme loads, and ensure the long-term reliability of the cable-stayed system. The four tensile concrete piers 4 are distributed in a radiating pattern around the base of the tower body 1. The radiating pattern of the four tensile concrete piers 4 around the base of the tower disperses the tension direction of the first steel wire rope 3, optimizes the load transfer path, enhances the tower's ability to resist multidimensional wind loads, and reduces stress concentration.

[0021] Please see Figure 1-2 A cross beam 8 is welded in the middle of the tower body 1. A lifting hole 9 is opened on the cross beam 8. A second steel wire rope 10 is attached to the lifting hole 9. The bottom end of the second steel wire rope 10 is connected to a pre-embedded lifting ring 12 fixed above the mass block 11. A fence 13 is set on the ground directly below the mass block 11. By setting the fence 13 directly below the mass block 11, the dangerous area is effectively isolated to prevent personnel or vehicles from accidentally entering and colliding with the mass block 11, reducing the risk of accidental injury, and at the same time avoiding the erosion of the ground when the mass block 11 swings.

[0022] Warning signs 14 are installed on all four outer sides of the enclosure 13. The warning signs 14 on the outer side of the enclosure 13 serve to visually alert people in the surrounding area to pay attention to safety. They are especially suitable for nighttime or low-visibility environments and comply with the safety regulations for power facilities.

[0023] The anchor rod 6 is equipped with barbs 7, which increases the friction between the anchor rod 6 and the soil, prevents the anchor rod 6 from slipping or loosening, and further improves the anchoring effect of the concrete pier in the soft soil foundation.

[0024] The working principle of this utility model is:

[0025] In use, anchor rods 6 and barbs 7 are first embedded deep into the ground through four radiating tensile concrete piers 4 to form a solid anchor point. Then, the two ends of the first steel wire rope 3 are fixed to the pull ring 2 on the tower body and the pull ring 5 on the pier body, respectively, to establish a multi-directional inclined cable network. After installation, when the tower is subjected to horizontal loads such as strong winds or earthquakes, the inclined cable immediately tightens, distributing the tension to the concrete piers and foundation, inhibiting the tower body from tilting or bending. Then, the suspended mass block 11 is connected to the lifting hole 9 of the cross beam 8 through the second steel wire rope 10, so that the total center of gravity of the tower body 1 is lowered, reducing the overturning moment, ensuring the safe operation of the tower in harsh environments, and extending its service life.

[0026] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
