Quakeproof platform for tower

Abstract

The invention discloses a quakeproof platform for a tower. The quakeproof platform for the tower comprises a support base (1), a damping structure and a connecting structure (10). An accommodation cavity (2) is formed in the center of the support base (1), a cover plate (3) is installed on the upper end face of the support base (1), and a through hole is formed in the center of the cover plate (3). The damping structure comprises a damping seat (4) and a connection rod (5), the damping seat (4) is installed in the accommodation cavity (2), the upper end of the connection rod (5) stretches out of the through hole, a sealing ring (6) is installed between the connection rod (5) and the cover plate (3), a reinforcing layer (7) which is interwoven transversely and longitudinally is installed in the sealing ring (6), and a plurality of disc spring buffering pieces are installed between the damping seat (4) and the accommodation cavity (2). According to the quakeproof platform for the tower, by installing disc spring buffering pieces between the support base and the damping seat and installing the sealing ring between the connection rod and the cover plate, rigid damage of transverse waves and longitudinal waves of earthquakes to electric poles is effectively prevented, and meanwhile, quakeproof platform for the tower has the advantages that manufacturing is easy, and installing is convenient.

Description

technical field [0001] The invention belongs to the technical field of power transmission lines, and in particular relates to a tower anti-vibration platform. Background technique [0002] At present, the tower design and structural safety and stability construction of 35KV and below power transmission and distribution lines in the power grid are relatively weak. The towers for power transmission and wiring are all equipped with thick cylinders at the bottom, with brackets at the top, and tree-like shapes at high altitude. It is suitable for erecting wires and cables, the bottom of which is connected by bolts to the foundation that is simply laid underground. However, this traditional rigid fixing method between the tower and the ground is difficult to resist the vibration of the foundation or the occurrence of earthquake disasters.

[0002] At present, the tower design and structural safety and stability construction of 35KV and below power transmission and distribution lines in the power grid are relatively weak. The towers for power transmission and wiring are all equipped with thick cylinders at the bottom, with brackets at the top, and tree-like shapes at high altitude. It is suitable for erecting wires and cables, the bottom of which is connected by bolts to the foundation that is simply laid underground. However, this traditional rigid fixing method between the tower and the ground is difficult to resist the vibration of the foundation or the occurrence of earthquake disasters. When an earthquake occurs, the foundation is often cracked and damaged. Uneven settlement, etc.; when natural disasters such as strong winds, heavy snow, heavy rain, and ice cover occur, the tower will be tilted and overturned like a "domino" effect. Power outages seriously endanger the safety of electricity and the electricity consumption of residents in production and life, and bring immeasurable losses to the national economy.

On August 14, 2013, a tornado hit Pushi Town, Luxi County, Xiangxi Autonomous Prefecture. After the tornado, the roofs of Neiwa houses in the town were overturned, and the utility poles collapsed in rows and fell on the roofs of residents or trees. More than 5 The 10 kV line was affected by the disaster, affecting nearly 100,000 residents in four villages and towns for production and living electricity. However, the current common method is to prefabricate concrete at the base, and then connect the bottom of the pole through the flange. If the concrete base is small It is easy to settle, and if it is very large, it will waste a lot of resources, and the flange connection method is easy to break under conditions such as strong winds and vibrations, and there are still major safety hazards. Therefore, how to design a new type of tower structure to make the disaster-resistant ability greatly improved

The disadvantage of this structure is that the connection between the pole and the base is still rigid, and the earthquake resistance is not strong in the face of the shear wave and longitudinal wave of the earthquake

The disadvantage of this structure is: the structure is complicated, and the installation process is time-consuming and laborious
