Abstract

The invention relates to a truss structure of a wind turbine generator set. The truss structure of the wind turbine generator set comprises steel-pipe piles (1), inserting sections (2), jacket pile legs (3), supporting steel pipes (4), a tower platform (5) and inclined struts (6), wherein the steel-pipe piles (1) extend into a supporting layer below the seabed, the inserting sections (2) are partly inserted into the upper ends of the steel-pipe piles (1), the jacket pile legs (3) are welded to the upper ends of the inserting sections (2), the supporting steel pipes (4) are welded between the two jacket pile legs (3), the tower platform (5) is arranged above the jacket pile legs (3) and the supporting steel pipes (4), and the inclined struts (6) are welded above the tower platform (5) and connected with a tower (7) arranged above the tower platform (5). Piling is carried out in advance, and the truss structure enables a steel structure and the steel-pipe piles to be integrated by inserting the inserting sections into the steel-pipe piles and then pouring binding materials, offshore workload of workers is reduced, offshore working time is shortened, influences of weather and climate changes on construction are less, and construction cost is reduced greatly.

Description

The truss type wind generating set structure

[technical field]

The present invention relates to the truss type wind generating set structure.

[background technique]

Wind-powered electricity generation is new energy with the fastest developing speed in the world wide, and Oversea wind power generation has then been represented the highest level of current wind power technology, requires highly reliable, the easy installation of equipment, easy care; Market scale is very big; Risk is also high, enjoys various countries to pay close attention to, and is starting the investment tide; At present existing more than 100 countries and regions begin to develop wind-powered electricity generation, and the staple market concentrates on Europe, Asia and North America.

China's sea turn resource reserve is abundant, and the primary condition of scale exploitation possesses.According to China Meteorological Administration's wind energy resources detailed survey initial achievements, but record 5 meters to 25 meters water depth lines of China with interior greater coasting area, about 200,000,000 kilowatts of 50 meters height wind-powered electricity generation electric motor power more than the sea level, but about 500,000,000 kilowatts of electric motor power more than 70 meters.

Because the particularity of offshore construction; At present under the technical specifications; Offshore wind generating group basis adopts the mode of concrete bearing platform to build usually; Since offshore construction receive easily the synoptic climate variable effect, great in constructing amount, the cycle is long, cost is high, the building-up work major part that the staff hopes offshore wind generating group base configuration is in factory or accomplish on the bank, reduces the time of offshore construction operation as far as possible.

[summary of the invention]

The present invention has overcome the deficiency of above-mentioned technology; Provide a kind of can be on land factory or seashore carry out manufacturing; The wind power generating set base configuration of installing through ship to specified position then; This structure is welded into space truss structure supporting wind power generating set by cylindrical shape steel structure rod member, this wind power generating set fondational structure make the staff at sea workload reduce, shorten the marine operating time; It is little that work progress receives the synoptic climate variable effect, significantly reduces construction cost.

For realizing above-mentioned purpose, the present invention has adopted following technical proposals:

The truss type wind generating set structure; Comprise steel pipe pile, part is inserted the insertion section of said steel pipe pile upper end, is welded in the said jacket spud leg that inserts the section upper end; Be welded in the supporting steel pipe between the said jacket spud leg; Be arranged at the pylon platform on said jacket spud leg and the said supporting steel pipe, be welded in the diagonal brace on the said pylon platform, said diagonal brace links to each other with tower tube on placing said pylon platform.

Steel pipe pile, said insertion section, said jacket spud leg, said supporting steel pipe and said diagonal brace are the cylindrical shape steel structure as stated.

Steel pipe pile is 3~8 as stated.

Steel pipe pile is 4 as stated.

The part of inserting as stated in the said steel pipe pile of section insertion is fixing through grouting material and said steel pipe pile bonding.

The invention has the beneficial effects as follows:

1, offshore wind generating group fondational structure according to the invention factory or seashore is carried out manufacturing on land, reduces a staff the time of construction at sea, shortens construction period, and it is little that working procedure receives the synoptic climate variable effect;

2, jacket spud leg and said supporting steel pipe form truss structure among the present invention, and easy installation and removal utilizes less material to obtain bigger rigidity, makes wind power generating set fondational structure reasonable, practices thrift cost.。

3, said truss structure bottom adopts the insertion section to insert in four steel pipe piles accomplishing fluently in advance among the present invention, has reduced structure weight, has practiced thrift old, makes things convenient for offshore construction and installation simultaneously.

[description of drawings]

Fig. 1 is a wind power generating set fondational structure front view of the present invention.

Fig. 2 is a wind power generating set fondational structure plan view shown in Figure 1.

[embodiment]

Below in conjunction with accompanying drawing the present invention is done further description.

Like Fig. 1, shown in Figure 2, the truss type wind generating set structure comprises the steel pipe pile 1 that stretches into the following supporting course of sea bed; Part is inserted the insertion section 2 of said steel pipe pile 1 upper end, is welded in the said jacket spud leg 3 that inserts section 2 upper ends, is welded in the supporting steel pipe 4 between the said jacket spud leg 3; Be arranged at the pylon platform 5 on said jacket spud leg 3 and the said supporting steel pipe 4, be welded in the diagonal brace 6 on the said pylon platform 5, said jacket spud leg 3 forms truss structure with said supporting steel pipe 4; Said diagonal brace 6 links to each other with tower tube 7 on placing said pylon platform 5; As one embodiment of the present invention, said diagonal brace 6 links together through the mode of welding with placing the tower tube 7 on the said pylon platform 5, and it is more firm to make tower tube 7 install; It is stronger to resist the external interference ability; A kind of work progress of the present invention is: manufacturing is carried out to steel pipe pile 1, said insertion section 2, said jacket spud leg 3, said supporting steel pipe 4, pylon platform 5 and said diagonal brace 6 in factory or seashore on land earlier, uses ship to specified position after accomplishing, and installs then; The work progress of this kind offshore wind generating group fondational structure reduces a staff the time of construction at sea; Shorten construction period, it is little that working procedure receives the synoptic climate variable effect, forms truss structure for jacket spud leg and said supporting steel pipe; Easy installation and removal utilizes less material to obtain bigger rigidity.

As shown in Figure 1; In the present invention; Said steel pipe pile 1, said insertion section 2, said jacket spud leg 3, said supporting steel pipe 4 and said diagonal brace 6 be the cylindrical shape steel structure, and the cylindrical shape steel structure is drawn materials easily, utilize the bigger rigidity of less material acquisition; Weight is lighter relatively, is convenient to installation and removal.

As shown in Figure 1, in the present invention, said steel pipe pile 1 is 3~8, is preferably 4, and 4 combine with said insertion section 2, said jacket spud leg 3, said supporting steel pipe 4, form pylon platform 5, thereby to wind power generating set formation mountion plate.

In the present invention, the said part of inserting in the said steel pipe pile 1 of section 2 insertions is fixing through grouting material and said steel pipe pile 1 bonding, and easy construction adapts to the adjustment of site error.
