Earthquake self-adaptation-type pole and tower device

Abstract

The invention discloses an earthquake self-adaptation-type pole and tower device which comprises a pole and tower body, a self-adaptation-type positioning base and pieces of concrete tower footing. Supporting stand columns are arranged at the bottom of the pole and tower body. The self-adaptation-type positioning base and the pieces of concrete tower footing are laid underground. The self-adaptation-type positioning base comprises base plates and a plurality of layers of pole holding devices, wherein the lower portions of the base plates are precast on the pieces of concrete tower footing, and the pole holding devices are arranged in a spatial-crossing mode. Bearing positioning components of the supporting stand columns are arranged in the middles of the base plates. Self-reset springs are arranged on the peripheral sides of the bearing positioning components and / or the lower portions of the pole holding devices, and positioning reference modules are arranged in the pieces of concrete tower footing. A position collection module connected with a controller is arranged at the upper portion of the pole and tower body. The controller is connected with an alarming module. According to the earthquake self-adaptation-type pole and tower device, the self-adaptation-type positioning base and the pieces of concrete tower footing are laid underground in an embedded mode, the foundation intensity, the structural stability and the earthquake-proof capacity are improved, foundation cracking and uneven settlement are effectively prevented, the controller of the pole and tower body is utilized for collecting position information and timely giving an alarm, the early warning and the outage are carried out before the maximum damage of the disaster is reached, and large-area damage and power failures of a power grid are avoided.

Description

technical field [0001] The invention belongs to the technical field of tower foundation design for power transmission and transformation engineering design and construction, and in particular relates to a vibration self-adaptive tower device. 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 improve and realize remote monitoring to reduce the accident rate has become a technical problem that people in the industry are working hard to solve.
