Problems solved by technology

[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.

Abstract

The invention discloses a transmission and transformation electro-vibration adaptive tower. The transmission and transformation electro-vibration adaptive tower comprises a tower body, an adaptive positioning base and a concrete tower footing, wherein a supporting upright column is arranged on the bottom of the tower body; the adaptive positioning base and the concrete tower footing are paved under the ground; the adaptive positioning base comprises a base plate and a plurality of layers of pole holding devices; the lower portion of the base plate is prefabricated on the concrete tower footing; the pole holding devices are distributed in space in a staggered mode; a bearing and positioning component of the supporting upright column is arranged in the middle of the base plate; self-resetting springs are arranged on the peripheral side of the bearing and positioning component and / or the lower portions of the pole holding devices; a positioning reference module is arranged in the concrete tower footing; and a plurality of rebars extending partially are arranged in the concrete tower footing and are connected with an auxiliary positioning base block. Foundation strength, structure stability and seismic capacity are improved, foundation cracking and differential settlement are prevented effectively, a controller of the tower body is used for acquiring position information and warns in time, early warning and power interruption are carried out before a disaster reaches a maximum extent, and large-area destruction of a power grid and power failure are avoided.

Description

technical field [0001] The invention belongs to the technical field of pole tower foundation design for power transmission and transformation engineering design and construction, and particularly relates to a power transmission and transformation vibration self-adaptive pole tower. 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.
