Description

A kind of large-scale wind driven generator is from rising tower crane construction method
Technical field
The present invention relates to field of new energy technologies, specially a kind of large-scale wind driven generator rises tower crane construction method certainly.
Background technique
With increasingly deficient and science and technology the rapid development of world energy sources, requirement of the people to environmental protection in addition, People are striving to find a kind of renewable, environmentally friendly, clean green energy resource that can substitute the energy such as petroleum, natural gas.Wind energy is A kind of current most promising new energy, it is the inexhaustible energy or a kind of cleaning, without dirt Dye, reproducible green energy resource.
China is the highest country of wind resource occupation rate in the world, and utilizes the country of wind energy earliest in the world One, according to statistics, 10m height layer wind energy resources total amount in China is 3226GW, wherein land wind energy total amount of exploiting is 253GW, in addition Oversea wind resource, China can utilize the nearly 1000GW of wind resource.If wind resource rate of exploitation reaches 60%, Only wind power generation one just can support the current whole electricity needs in China.
With Chinese large-sized Wind turbines develop work accelerate, originally large-scale wind electricity unit substantially rely on into Mouthful, by developing for many years, nowadays, the main component of large-scale wind electricity unit realizes production domesticization substantially, meanwhile, with Wind-driven generator manufactures the progress of technology, and wind-driven generator manufacture is increasing, from original 1MW, 1.5MW, 2MW etc., development To current 2.5MW, 3MW, 3.6MW, 6MW etc., blade is increasingly longer, increasing, and assembling height is higher and higher, by original 60m, 70m, 80m, the 90m ... come, develops to current 120m, 140m, 160m ..., therefore, in the complex environments such as mountain area, coastal The installation of large-scale wind driven generator equipment brings difficulty.
It investigated, looked into the wind power plant construction newly, being completed both at home and abroad at present, traditional wind-driven generator is usually used Installation method: i.e. crawler crane serves as hanging device leading role, autocrane stooge.But with mounting height Higher and higher, the large caterpillar needed is increasing, is increasingly difficult to meet, and at high cost.This construction method exist with Lower disadvantage: 1, the shortcoming of giant caterpillar formula crane is that in assembled boom, required place is larger, for example boom has 100 Rice, required place is just at 100 meters or more, and on mountain or seashore is difficult to find suitable place splicing, and before crawler crane Phase assembling is very cumbersome, is not suitable for using in the situation with a varied topography of the fields such as mountain area, forest zone, coastal;2, the wind-powered electricity generation peace in China Dress is general all under complex environment, and the every lifting for completing a place of giant caterpillar formula crane requires fission and transports down One job site, is assembled again, thus efficiency is very low, unfavorable save the cost;3, certainly due to giant caterpillar formula crane Great, transition transport is high for wind power plant rto request, cost of idleness.4, wind-driven generator installation period, duration are influenced Long, work efficiency is low.
Summary of the invention
The purpose of the present invention is to provide a kind of large-scale wind driven generators from tower crane construction method is risen, and is suitable for coastal, mountain The installation of the large-scale wind driven generator of the various complicated environmental conditions such as area, accelerates construction speed, reduces cost, investment reduction, To solve complex condition mentioned above in the background art, the higher and higher construction of large-scale wind driven generator mounting height is difficult Topic.
