Description

Technical Field

[0001] The invention relates to the technical field of transmission towers, and in particular to a transmission tower with a protective function. Background Art

[0002] Transmission towers are an indispensable key equipment in modern power transmission systems. They are responsible for supporting transmission lines and ensuring that electricity is reliably transmitted from power stations to users. With the rapid development of social economy and the continuous growth of electricity demand, the importance of transmission towers in power grid construction has become increasingly prominent. It is not only an important infrastructure for power transmission, but also bears the important responsibility of maintaining the stable operation of the power grid.

[0003] Early transmission towers were relatively simple in design, mainly made of wood. However, with the expansion of power systems and the increase in voltage levels, traditional materials can no longer meet the needs of high loads and long-distance transmission. Modern transmission towers are generally made of steel structures or reinforced concrete to improve the strength and durability of the tower. At the same time, the design of transmission towers is constantly being optimized to adapt to various complex terrains and extreme climatic conditions, such as mountainous areas, deserts, and high-cold areas.

[0004] Transmission towers not only need to support high-voltage wires, but also need to ensure that there is a sufficient safe distance between the wires, and between the wires and the ground or other obstacles to prevent electrical flashover or other accidents. In addition, transmission towers also need to withstand multiple external forces such as wind loads, ice and snow loads, and earthquake loads, so their structural design must take into account strength, stability, and economy. In order to reduce the impact of the line on the environment, modern transmission towers are gradually incorporating environmental protection concepts into their design, such as reducing the area occupied by the tower base and optimizing the line layout.

[0005] With the advancement of power technology, the functions of transmission towers have gradually expanded from single line support to diversified applications. For example, in UHV transmission systems, transmission towers need to support higher voltage levels and longer transmission distances; in smart grids, transmission towers can be equipped with sensors and communication equipment to achieve real-time monitoring of line status and data transmission. These technological improvements have made transmission towers not only physical carriers, but also important nodes in smart grids; There are still the following defects in specific use: 1. The displacement of the conductor may cause friction between it and the transmission tower or other supporting structures, thereby wearing out the insulation layer on the surface of the conductor and reducing the insulation performance of the conductor. At the same time, long-term displacement and shaking may cause the stability of the transmission tower to decrease, and even cause the risk of the tower body tilting or collapsing. In addition, the weight of ice and snow may overload the conductor, causing the conductor to break or the transmission tower to collapse, and the displacement of the conductor may cause line interruption and affect power supply. Especially in areas with higher altitudes, the lines are more seriously affected by the climate, the line icing phenomenon is more common, and the long-term load of the line is serious, which makes the wire tower subject to greater and longer tension, and eventually tilts and bends.

[0006] 2. In addition, high-voltage hot spots may cause local overheating of the wire. When the temperature exceeds the melting point of the wire, the wire will melt. Hot spots may cause damage to insulators, lightning arresters and other equipment, causing equipment failure. Hot spots may also cause arc discharges, posing a risk of electric shock to nearby personnel. During maintenance or overhaul, personnel may suffer electric shock due to contact with hot spots.

[0025] The complete working principle and steps of the above embodiment are as follows: Initial definition: The transmission tower body 1 is an important device for supporting high-voltage transmission lines. Its main function is to support the conductor 11 and the insulator 12 through a high-strength structure, and to ensure the stability and safety of the conductor 11, avoid contact with the ground or other objects, and ensure efficient transmission of electricity. The working process of the transmission tower body 1 involves the synergistic effect of the conductor 11, the insulator 12 and the tower body.

[0026] After the electric energy is output from the power station, it is transmitted to the user end through the transmission line. The conductor 11 is an important part of the transmission tower body 1 and is used to transmit electricity. These conductors 11 are usually made of high-strength aluminum alloy or steel-core aluminum stranded wire, which can withstand huge tensile force and current transmission load. On the transmission tower body 1, the conductor 11 is isolated from the tower body by insulators 12 to prevent the current from leaking to the ground through the tower body. The insulator 12 is usually made of ceramic or composite materials and has high insulation performance and mechanical strength.

[0027] In actual operation, the tower body of the transmission tower main body 1 bears the vertical tension from the conductor 11 and external loads such as wind and ice and snow. When the conductor 11 is suspended in the air, a certain amount of sag will be generated due to its own weight and external forces. The transmission tower main body 1 controls the sag within a safe range by distributing the reasonable distance between towers and the suspension points of the conductor 11 to prevent the conductor 11 from touching the ground or other structures.

[0028] At the same time, the insulator 12 string is precisely arranged and installed to effectively fix the conductor 11 on the tower body and prevent the current from leaking into the tower body. The number and arrangement of the insulators 12 are determined according to the voltage level of the transmission line. During operation, the insulators 12 not only need to withstand mechanical stress, but also need to ensure that their insulation performance is not affected by environmental pollution or humid climate during long-term operation.

[0029] The design of the transmission tower body 1 also takes into account the need for lightning protection. A lightning rod or ground wire is usually set on the top of the tower to guide lightning into the ground to protect the conductor 11 and other equipment from damage. In addition, the tower base of the transmission tower body 1 uses a good grounding system to quickly guide the possible leakage current into the ground to avoid harming the nearby environment.

[0030] When using: The balance reset mechanism 2 for automatically adjusting the tension difference between the conductors 11 has the following steps: like Figure 3 to Figure 4 As shown, when the conductor 11 is displaced by external factors such as wind load, ice and snow, or thermal expansion and contraction, the operator can start the electric telescopic rod 24, so that the electric telescopic rod 24 moves upward and extends, thereby pushing the double-headed rod 23 fixedly connected at one end thereof to be ejected upward, so that the right slide column 25 and the left slide column 27 fixedly connected to the two sections of the double-headed rod 23 will move upward synchronously. When the drooping height of the left end of the conductor 11 is higher than that of the right side, since the diameter size of the top end of the long tooth plate 28 is larger than the diameter size of the short tooth plate 26, the left slide column 27 drives the long tooth plate 28 to move so that the long tooth plate 26 The groove at the top of the plate 28 will first move to engage with the outer wall of the wire 11, so that the continued movement will cause the drooping left end wire 11 to be lifted and reset, so that the reset wire 11 will add a thrust to the long tooth plate 28 in the reverse direction, so that the long tooth plate 28 will move in the reverse direction to make the ring gear 210 meshing with it rotate counterclockwise, so that the short tooth plate 26 meshing with the ring gear 210 will continue to move upward with the rotation of the ring gear 210 until the groove opened at its top engages with the outer wall of the wire 11, so as to play the role of adjusting, supporting and fixing the wire 11 corresponding to the long tooth plate 28; Similarly, when the sagging height of the right end of the wire 11 is higher than that of the left side, since the diameter of the top of the short-tooth plate 26 is smaller than the diameter of the long-tooth plate 28, the right slide column 25 drives the movement of the short-tooth plate 26 so that the groove at the top of the short-tooth plate 26 will first move to engage and contact the outer wall of the wire 11, thereby continuing to move and causing the sagging right end of the wire 11 to be lifted and reset. After the reset, the short-tooth plate 26 will add a thrust to the short-tooth plate 26 in the reverse direction, so that the short-tooth plate 26 will move in the reverse direction and cause the ring gear 210 meshing with it to rotate clockwise. In this way, the long-tooth plate 28 meshing with the ring gear 210 will continue to move upward with the rotation of the ring gear 210 until the groove opened at its top engages and contacts the outer wall of the wire 11, thereby corresponding to the short-tooth plate 26 to play a role in adjusting, supporting and fixing the wire 11.

[0031] Current guiding mechanism for guiding current to flow along a predetermined path 3 steps: like Figure 5 to Figure 6 As shown, when the ring gear 210 rotates, the spherical connecting rod 31 fixedly connected to the outer wall of one side thereof will rotate, and then the universal ball 32 rotatably connected to the outer wall of one end of the spherical connecting rod 31 will also rotate, thereby the bearing telescopic column 33 rotatably connected to the outer wall of one end of the universal ball 32 will swing back and forth and move up and down as the universal ball 32 rotates, so the connecting rod 34 rotatably connected to the upper end of the bearing telescopic column 33 will rotate as the bearing telescopic column 33 swings, and the rotation of the connecting rod 34 will cause the inner obstacle column 35 fixedly connected at one end thereof to push the square rod 36 clamped on its outer wall to move laterally, so that the lateral movement of the square rod 36 will pull the outer obstacle column 37 clamped at one end thereof to move synchronously, and the cross rod 38 rotatably connected to the bottom end of the outer obstacle column 37 will rotate along with the outer obstacle The movement of the barrier column 37 has an expansion and contraction trend, and the expansion and contraction movement of the cross rod 38 will cause the short-circuit rod 39 connected to one end of the cross rod 38 to expand and contract. In addition, there are multiple cross rods 38 symmetrically connected to rotate along the outer wall of the arc-shaped slide slot 312, and the central outer walls of the multiple cross rods 38 are fixedly connected with drainage needles 311. Therefore, after one of the cross rods 38 follows the lateral movement of the square rod 36 and has an expansion and contraction trend, it will pull the remaining multiple cross rods 38 to move in a streamlined trajectory inside the arc-shaped slide slot 312. In this way, the movement of the arc-shaped slide slot 312 will prevent the drainage needle 311 from interfering with the current flow path covered by the drainage needle 311 on the outer wall of the drooping wire 11, thereby preventing unnecessary short circuits between the wire 11 and other metal objects or the ground. The sag suppression mechanism 4 steps for effectively dispersing the pressure generated by the sag of the conductor 11 are as follows: like Figures 7 and 8As shown, when the square rod 36 moves laterally, it will synchronously drive the external block 41 fixedly connected to its surface to move, and then the wedge-shaped rod block 42 slidably connected to the outer wall of one side of the external block 41 will be squeezed by the external block 41 to move up and down, so that the friction ring 43 rotatably connected to one end of the wedge-shaped rod block 42 will move upward to abut against the lower outer wall of the conductor 11, and at the same time, the upward movement of the wedge-shaped rod block 42 will cause the sliding ring 44 sliding on the outer walls on both sides to slide synchronously, so that the swing rod 45 rotatably connected to the outer wall of the sliding ring 44 will deflect inward in the opposite direction, and then the extrusion ring 46 rotatably connected to the inner wall of one end of the swing rod 45 will clamp the lower outer wall of the transmission tower body 1 in the opposite direction, thereby limiting the excessive sagging of the conductor 11, thereby reducing the risk of the conductor 11 being broken due to excessive bending or concentrated tension. Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
