Description

Technical Field

[0001] The present application relates to the field of power poles and towers, and in particular to a power pole tower with anti-seismic and shock-absorbing functions. Background Art

[0002] The transmission line poles currently used in the existing power system are generally cement poles or ordinary steel metal poles. There are no problems under normal use conditions. However, once an earthquake or severe ice and snow disaster occurs, or when hit by a vehicle or heavy object, it is easy to cause tower collapse or safety hazards.

[0003] The Chinese patent "A power pole tower with anti-seismic and shock-absorbing functions" (patent number: 202021546589.2) has design innovations in key parts such as the anti-seismic composite gasket at the bottom of the pole body, the anti-seismic flange, and the anti-seismic energy dissipation stiffened plate. The standardized design of the anti-seismic composite gasket is convenient for selection, and the anti-seismic flange is connected to the pole tower base flange through the anti-seismic composite gasket and the anti-seismic flange bolts, which can reduce the number of collapsed towers under earthquake limits and impact stress limits by 70-90%.

[0004] However, the seismic composite gaskets, seismic flanges, and seismic energy dissipation stiffened plates in the above-mentioned patents cannot absorb the impact force generated by earthquakes in multiple stages, and most of them are exposed to the air. Long-term exposure to wind and sun can easily cause oxidation and rust on the surfaces of the seismic composite gaskets, seismic flanges, and seismic energy dissipation stiffened plates, reducing fatigue life. When the pole tower shakes violently, the seismic resistance effect is poor and the connection is not firm, which may cause the pole tower to break and collapse, reducing safety.

DETAILED DESCRIPTION

[0023] The following is combined with Figure 1-6 This application is described in further detail.

[0024] The embodiment of the present application discloses a power pole tower with anti-seismic and shock-absorbing functions.

[0025] Example 1

[0026] Reference Figure 1 and 2A power pole tower with anti-seismic and shock-absorbing functions, comprising a base 2 and a power pole tower body 1 at the upper end, the base 2 is made of stainless steel, the base 2 is square in structure, the inner diameter of the inner cavity of the base 2 is matched with the diameter of the buffer seat 3, a groove 19 is provided on one side surface of the base 2, and sliding grooves 4 are symmetrically provided on the inner wall surface of the groove 19, the inner wall of the inner cavity of the groove 19 is movably connected with the buffer seat 3, and the two side surfaces of the buffer seat 3 are fixedly connected with sliding plates 5, and the two sliding plates 5 are movably connected with the two sliding grooves 4 The top surface of the buffer seat 3 is bolted to the power tower body 1, and the inner wall surface of the groove 19 is fixedly connected with a sealing layer, and the sealing layer is made of rubber material, so that a sealed cavity is formed between the groove 19 and the buffer seat 3, which avoids the leakage of lubricating oil inside the groove 19 and causes the power tower body 1 to shake. The sliding plate 5 makes the buffer seat 3 suspended inside the groove 19, and the sliding plate 5 can drive the buffer seat 3 to slide slightly in the groove 19, and the sliding plate 5 can limit the buffer seat 3.

[0027] Reference Figure 2 and 3 The inner cavity surface of the buffer seat 3 is fixedly connected with a fixed rod 6, and the outer surface of the fixed rod 6 is symmetrically sleeved with a sliding block 8, the sliding block 8 and the fixed rod 6 are movably connected, and the outer surface of the fixed rod 6 is coated with lubricating oil, which can reduce the friction and wear between the sliding block 8 and the fixed rod 6, reduce the friction resistance, and can better buffer the seismic energy, thereby increasing the stability of the power tower body 1. Both ends of the fixed rod 6 are located on one side of the sliding block 8 and are sleeved with a spring 7, and the two sliding blocks 8 are fixedly connected to the inner wall of the buffer seat 3 through the spring 7, one end of the two springs 7 is fixedly connected to one side surface of the two sliding blocks 8, and the other end of the two springs 7 is fixedly connected to the inner wall of the inner cavity of the buffer seat 3, and the kinetic energy of the sliding block 8 can be absorbed by the spring 7, and the impact force of the seismic energy can be buffered, further reducing the vibration of the power tower body 1 and improving the stability. This is the third stage of absorption of the earthquake impact force.

[0028] Reference Figure 2 and 3A notch is provided on one side surface of the buffer seat 3, and a buffer block 12 is movably connected to the inner wall of the notch. A sealing layer is fixedly connected to the outer surface of the buffer block 12, and the sealing layer is made of rubber material. The sealing layer can form a sealed cavity between the buffer block 12 and the inner cavity of the buffer seat 3, thereby preventing the lubricating oil from entering the inner cavity of the buffer seat 3 from the inside of the groove 19, causing the lubricating oil in the inner cavity of the groove 19 to be lost, thereby reducing the absorption effect of the impact force. A fixed block 11 is fixedly connected to one side surface of the buffer block 12, and the fixed block 11 and the two sliding blocks 8 are hinged by a connecting rod 10. The hinges between the connecting rod 10 and the fixed block 11 and the two sliding blocks 8 are coated with lubricating oil, which can reduce the friction and wear between the connecting rod 10 and the fixed block 11 and the two sliding blocks 8, thereby increasing the service life.

[0029] Reference Figure 3 The outer surface of the fixing rod 6 is fixedly connected with a mounting seat 18, and a damper 9 is bolted to one side surface of the mounting seat 18. One end of the damper 9 is connected to the mounting seat 18 by a fastening bolt, and the other end of the damper 9 is against the top surface of the fixing block 11. The damper 9 can buffer the kinetic energy of the buffer block 12, thereby controlling the vibration or rebound of the buffer block 12 and maintaining the stability of the buffer block 12.

[0030] Reference Figure 4 and 6 A sealing plate 14 is fixedly connected to one side surface of the buffer block 12, and a plurality of energy absorption holes 20 are opened on the bottom surface of the sealing plate 14. The interiors of the plurality of energy absorption holes 20 are filled with butyl rubber. The butyl rubber in the energy absorption holes 20 has good shock absorbing performance and can disperse and absorb the impact force of the sealing plate 14, thereby increasing the absorption effect of the sealing plate 14.

[0031] Reference Figure 2 and 4 , a sealing sleeve 15 is fixedly connected to the outer surface of the sealing plate 14, and an oil storage cavity is formed between the sealing sleeve 15 and the groove 19 and the oil groove 17, which prevents the lubricating oil from dripping on the surface of the fine sand and causing leakage of the lubricating oil. An energy-absorbing pad 13 is fixedly connected to the bottom of the inner cavity of the groove 19. The energy-absorbing pad 13 has a concave structure and is made of butyl rubber. The energy-absorbing pad 13 is bonded to the bottom of the inner cavity of the groove 19 by high-temperature resistant glue, which prevents the surface of the energy-absorbing pad 13 from being loosened and wrinkled, resulting in a reduced absorption effect on the impact force. The inner surface of the energy-absorbing pad 13 is filled with fine sand, and gaps are left between the fine sand, which turns the impact into kinetic energy of the movement of the sand and disperses it. The fine sand further absorbs the impact force and can timely slow down a large amount of impact, which is similar to the principle of paving the rails with stones. The stones can increase the elasticity of the track and reduce the impact on the rails, thereby achieving a shock-absorbing effect. The fine sand can absorb the impact force, which is the first stage of the absorption of the earthquake impact force.

[0032] Reference Figure 2 An oil groove 17 is provided on the inner side of the base 2. The oil groove 17 is L-shaped. The inner wall of the oil groove 17 is smooth. The lubricating oil contains rubber plastic particles. The oil groove 17 is connected to the groove 19. Lubricating oil is injected into the oil groove 17 so that the lubricating oil is stored on the upper surface of the sealing sleeve 15. When the sealing sleeve 15 is squeezed upward by the impact force, the rubber plastic particles in the lubricating oil are squeezed through the sealing sleeve 15, so that the rubber plastic particles are in a compressed state. The compressed rubber plastic particles can buffer and absorb the impact force, which is the second stage of absorption of the earthquake impact force.

[0033] The inner wall of the inner cavity at one end of the oil groove 17 is threadedly connected to a breathable cover 16, the breathable cover 16 is a hollow structure, and a breathable hole is provided on one side surface of the breathable cover 16. The breathable cover 16 is a T-shaped structure, and an internal thread is provided on the inner wall of the inner cavity at one end of the oil groove 17, and an external thread matching the internal thread is provided on the outer surface of the bottom end of the breathable cover 16, and the air inside the oil groove 17 can be discharged through the breathable hole.

[0034] By coordinating the first, second and third stages of seismic energy absorption, the impact force of the earthquake can be absorbed and reduced in sections, which buffers most of the impact force and greatly improves the stability of the power tower body 1.

[0035] The implementation principle of an electric pole tower with anti-seismic and shock-absorbing functions in the embodiment of the present application is as follows: first, a foundation is dug at a suitable position, a base 2 is placed inside the foundation, concrete is poured into the foundation, and when the concrete is completely solidified, the electric pole tower body 1 is fixedly installed on the top surface of the buffer seat 3 by bolts. After the fixed installation is completed, the breathable cover 16 is unscrewed, and the lubricating oil containing rubber and plastic particles is poured into the inner side of the oil tank 17. The lubricating oil is drained into the groove 19 through the oil tank 17. When an earthquake occurs, the energy generated by the earthquake impacts the bottom of the base 2, causing the bottom of the base 2 to vibrate, and the vibration energy is transmitted upward through the energy-absorbing pad 13, and the vibration energy is dispersed and absorbed by utilizing the gaps between the fine sand. The fine sand can initially resist the impact force. The residual energy of the earthquake continues to be transmitted upward, and the sealing sleeve 15 is impacted upward by the residual energy, so that the sealing sleeve 15 moves slightly upward. The sealing plate 14 uses the butyl rubber inside the energy absorption hole 20 to absorb the impact force for the second time. At the same time, the sealing sleeve 15 drives the buffer block 12 to move upward, and the rubber plastic particles in the lubricating oil are squeezed by the sealing sleeve 15, so that the rubber plastic particles absorb the impact force for the third time. The buffer block 12 transfers kinetic energy to the connecting rod 10 through the fixed block 11, so that the sliding block 8 expands outward and moves laterally on the surface of the fixed rod 6, and the spring 7 is squeezed by the sliding block 8. The spring 7 absorbs the kinetic energy generated by the sliding block 8, thereby improving the stability of the buffer block 12.

[0036] At the same time, the damper 9 can buffer the kinetic energy of the fixed block 11, maintain the stability of the buffer block 12, and can absorb and damp the impact force in multiple stages through fine sand, rubber plastic particles in the lubricating oil and the buffer seat 3, thereby reducing the impact force on the power tower body 1, greatly improving the seismic effect of the power tower body 1, and ensuring the effective power supply and power needs for emergency rescue when a disaster occurs, thereby improving safety.

[0037] 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.
