Description
Technical field
The invention belongs to transmission line of electricity technical field, more particularly, to a kind of shockproof electric pole firm banking.
Background technology
At present, the 35KV of electrical network and the design of following electric line electric pole and structure security and stability construction aspect relative thin
Weak, transmission of electricity, the electric pole of stringing are all in the thick cylinder of bottom setting, and top is provided with support, and high-altitude is in tree-shaped, for setting up
Electric wire, its bottom is simply laid in by bolt connection the ground of underground, but the rigidity on this traditional electric pole and ground
Fixed form be difficult to resist ground produce vibrations or occur earthquake disaster, when occur earthquake when, often result in basis cracking and not
Uniform settlement etc.；When there is the natural disasters such as strong wind, heavy snow, heavy rain, icing, electric pole is whole as " dominoes " effect
Bar, whole section of listing and sinking, or even the damage etc. that fractures, often result in destruction and the power outage of electric grid large area, serious harm
Electric power safety and resident's productive life electricity consumption, bring immeasurable loss to national economy.On August 14th, 2013, dragon
After volume wind attacks Xiangxi Autonomous Prefecture Luxi County Pu town, tornado suddenly, thrown in this town town Neva house top, electric pole in a row falls
Collapse and pound on the roof of resident family or trees, impact four small towns nearly ten ten thousand resident's productive lifes disaster-stricken more than 5 10 KVs
Electricity consumption, but, the mode commonly used at present is exactly in base position precast concrete, then connects the bottom of line bar by ring flange
Portion, if volume of concrete small base easily settles, if very big waste a lot of resources again, and ring flange connected mode is big
Easily break when wind, vibrations, however it remains larger potential safety hazard, therefore, how to design a kind of new electric pole structure
So that resist disaster ability being greatly improved.
Application number CN201510833079.0 discloses a kind of electric pole anti-shock mechanism, and including base, base upper surface is provided with
