Abstract
The utility model relates to a cylindrical tower barrel used for a large-scale wind generating set. The cylindrical tower barrel comprises a tower barrel body; upper 1/5 of the tower barrel body is of a conical shape, and lower 4/5 tower barrel body is a cylindrical shape; and the tower barrel body is of a split connecting structure; and the connection is fixedly connected through an annular clamping plate. Compared with the existing conical shaped tower barrel, the cylindrical tower barrel of the large-scale wind generating set has the advantages that the tower barrel shape is more beneficial for assembling of an elevator in a tower under the promise that the strength and the firmness are guaranteed, and the limit for the lift height of the elevator is greatly reduced, and the elevator is guaranteed to be lift up to a higher height, thereby leading the further maintenance operation to be more convenient, and reducing the maintenance cost; meanwhile, the split connected structure of the tower barrel reduces the degrees of difficulty of production, transportation and the like.
Description
Technical field
The utility model relates to a kind of cylindrical column tube that is used for Large-scale Wind Turbines.
Background technique
At present, the tower tube of many Large-scale Wind Turbines adopts conical structure, and this structure has certain advantage, and is better as steadiness, but this structure is unfavorable for the installation of elevator, and can limit the lifting height of elevator greatly.Along with the increase of installation quantity, the situation that the attendant is in short supply day by day simultaneously in order to reduce maintenance cost, improves maintenance efficiency, and the tower tube is equipped with the elevator trend that is inevitable.In order to make blower fan catch more wind energy, the tower tube also can be built higher and higher, along with increasing of tower tube is thick, has brought increasing difficulty for the production of tower tube and transportation.
The model utility content
The technical problems to be solved in the utility model is: a kind of cylindrical column tube that is used for Large-scale Wind Turbines is provided, be unfavorable for the elevator installation, make the limited problem of lifting height of lift to solve present conical tower tube, solve also simultaneously that present tower cylindrical shell is long-pending, weight is bigger, be not easy to the problem of transporting and installing.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of cylindrical column tube that is used for Large-scale Wind Turbines, has tower tube body, last 1/5 stack shell of tower tube body is conical, 4/5 stack shell is cylindrical and is the branch attachment structure down, and the joint is affixed by annular clamping plate.This is used for the cylindrical column tube of Large-scale Wind Turbines because following 4/5 stack shell of its tower tube body is cylindrical, therefore help the assembling work of elevator in the tower, and greatly reduce restriction to lifting height of lift, guarantee that elevator can be thus lifted to higher height; And divide attachment structure to reduce production, the transport difficulty of tower tube.
Say further, the junction point of two sections stack shells that split connects all fixedly is equipped with the annular inner splint that adapts with barrel dliameter separately, the annular inner splint butt joint of two sections stack shell junction points, annular external splint hoop is embraced two annular inner splints, and is affixed by bolt and nut between two annular inner splints and the annular external splint.
The beneficial effects of the utility model are: this cylindrical column tube that is used for Large-scale Wind Turbines is compared with present conical tower tube, under the prerequisite of proof strength and steadiness, its tower more helps the assembling work of elevator in the tower, and reduced restriction largely to lifting height of lift, guarantee that elevator can be thus lifted to higher height, thereby more help upkeep operation in the future, reduce maintenance cost; Simultaneously, the structure of the split of tower tube connection has reduced its production, transport difficulty.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the structural representation that is used for the cylindrical column tube of Large-scale Wind Turbines of the present utility model;
Fig. 2 is the assembly structure schematic representation that is used for the cylindrical column tube of Large-scale Wind Turbines of the present utility model.
Among the figure: 1. tower tube body 2. annular inner splint 3. annular external splints
Embodiment
A kind of cylindrical column tube that is used for Large-scale Wind Turbines, as shown in Figure 1 and Figure 2, it has tower tube body 1, and last 1/5 stack shell of tower tube body 1 is conical, and 4/5 stack shell is cylindrical and is the branch attachment structure down, and the joint is affixed by annular clamping plate.This is used for the cylindrical column tube of Large-scale Wind Turbines because following 4/5 stack shell of its tower tube body is cylindrical, therefore help the assembling work of elevator in the tower, and greatly reduce restriction to lifting height of lift, guarantee that elevator can be thus lifted to higher height; And divide attachment structure to reduce production, the transport difficulty of tower tube.
The junction point of two sections stack shells that split connects all fixedly is equipped with the annular inner splint 2 that adapts with barrel dliameter separately, annular inner splint 2 butt joints of two sections stack shell junction points, annular external splint 3 hoops are embraced between 2, two annular inner splints 2 of two annular inner splints and the annular external splint 3 affixed by bolt and nut.
Claims (2)
1. a cylindrical column tube that is used for Large-scale Wind Turbines has tower tube body (1), it is characterized in that: last 1/5 stack shell of tower tube body (1) is for conical, and 4/5 stack shell is cylindrical and is the branch attachment structure down, and the joint is affixed by annular clamping plate.
2. the cylindrical column tube that is used for Large-scale Wind Turbines according to claim 1, it is characterized in that: the junction point of two sections stack shells that split connects all fixedly is equipped with the annular inner splint (2) that adapts with barrel dliameter separately, annular inner splint (2) butt joint of two sections stack shell junction points, annular external splint (3) hoop is embraced two annular inner splints (2), and is affixed by bolt and nut between two annular inner splints (2) and the annular external splint (3).
