Abstract
The invention discloses a kind of tangent line is to La Lasuo and uses the wind power generation stepped of the drag-line.Tower position below wind power generation stepped impeller, will be separately fixed in the tangential direction of tower wall both sides by bolt joint in the middle part of two prestressed cables, and drag-line two ends anchor on the ground.Because drag-line is without tower center, cable tension provides initial torsional rigidity to tower, it is to avoid the fatigue problem that the frequent twisting vibration of tower brings to drag-line node, in addition, bolt joint is connected using shearing bolt with barrel, it is to avoid be welded to connect, and improves anti-fatigue performance.
Description
Technical field
The invention belongs to wind power generation stepped design field, and in particular to a kind of tangent line is to drawing stayed structure and using the drawing
Cable Structure it is wind power generation stepped.
Background technology
Development and the limitation of China's power transmission capacity with wind-power electricity generation cause, current China gradually start exploitation
The wind-power electricity generation resource in low wind speed area.To obtain preferable wind-resources, unit installed capacity and wind-power electricity generation tower height degree all by
Step increases, and in the case, traditional wind-power electricity generation tower structure cannot meet structure under conditions of existing transport, construction
The requirement of strength and stiffness, detrimental effect is all caused to generating efficiency and structure safely.To improve conventional wind power generation column
Tower rigidity and bearing capacity, it is necessary to set drag-line on tower body height, be anchored in ground, and use special connection shape
Formula, to avoid drawing fatigue rupture of the ear in wind power generation stepped twisting vibration.
The content of the invention
It is an object of the invention to the shortcoming for overcoming prior art to exist, there is provided a kind of tangent line is cut to La Lasuo and using this
Line provides anti-side rigidity to the wind-power electricity generation tower structure of La Lasuo to steel tower tube, improves tower lateral loading ability, low to meet
The requirement of wind speed area generating high tower.
To realize above-mentioned technical purpose, the present invention is adopted the following technical scheme that：
A kind of tangent line is to La Lasuo, including prestressed cable, ground anchor structure and bolt joint, it is characterised in that institute
Bolt joint is stated on the tower wall of a certain height and position of high tower, two middle parts of prestressed cable are by bolt joint point
It is not fixed in the tangential direction of both sides tower wall；Two ground anchor structures are arranged on the ground of high tower both sides, by two
The two ends of prestressed cable are separately fixed at together.
Preferably, the angle that two anchor points of ground anchor structure are formed with tower in the line of the kernel of section on ground is installed
Spend is 180 °.The ground anchor structure can be anchor ring or other fixed structures.
Further, the bolt joint includes train wheel bridge, lower plate, pressing plate and bolt, wherein train wheel bridge and lower plate
Between form duct, passed through for prestressed cable；Pressing plate is covered on train wheel bridge, lower plate and prestressed cable, and by passing through
Be close on tower wall for they by the bolt worn.
Preferably, the thickness of the train wheel bridge and lower plate is slightly less than the diameter of prestressed cable, by pressing plate, up and down presss from both sides
The run through bolt of plate and tower wall applies pressure to the prestressed cable in duct, so as to produce frictional force to avoid pre- answering
Power drag-line is slided in duct.
A kind of to use above-mentioned tangent line to the wind power generation stepped of La Lasuo, including basis, tower and draught fan impeller, its feature exists
In the certain position in wind power generation stepped tower, below draught fan impeller sets bolt joint, fixedly mounts one or more groups of
The tangent line is to La Lasuo.
Every group of tangent line includes two prestressed cables to La Lasuo, is symmetricly set in the tangential direction of tower wall both sides.
It is preferred that using two groups of tangent lines to La Lasuo, two groups of tangent lines are 90 ° to the angle between La Lasuo.3 groups or more can also be set
Group tangent line is arranged La Lasuo in a circumferential direction.
For ease of the fixation of bolt joint, the wind power generation stepped tower is preferably steel tower tube.
Specific implementation step is as follows：
(1) wind power generation stepped steel tower tube, and the appropriate location arrangement bolt hole under the draught fan impeller of tower are set up, is used for
Installation bolt node；
(2) some groups of drag-lines are arranged, is fixed on tower wall using bolt joint, and bypass tower, end sets in 180 degree
Put on the ground；
(3) it is the wind power generation stepped initial lateral rigidity of offer and torsional rigidity to the symmetrical applying pretension of drag-line.
Tangent line provided by the present invention is wind power generation stepped to La Lasuo, the tower position below impeller, using bolt section
Point fixes prestressed cable on tower wall, and anchors on the ground, to being same to drag-line, is only consolidated on tower wall
It is fixed, and all drag-lines, without tower center, cable tension provides initial torsional rigidity to tower, it is to avoid the frequent torsion of tower
The fatigue problem brought to drag-line node is vibrated, additionally, bolt joint is connected using shearing bolt with barrel, it is to avoid welding connects
Connect, improve anti-fatigue performance.

Specific embodiment
With reference to the accompanying drawings, it is wind power generation stepped to La Lasuo to the tangent line for providing of the invention to carry out with reference to one embodiment
Detailed description.
Referring to Figures 1 and 2, two groups of tangent lines of the wind power generation stepped structure setting of the present embodiment are to La Lasuo, two groups of drag-lines
Into right-angled intersection, totally four prestressed cables.
The every middle part of prestressed cable 2 is fixed in wind power generation stepped tower 1 by bolt joint 3, and bypasses tower extremely
To two ends are fixed on anchor point 4.As shown in Figure 3 and Figure 4, bolt joint 3 is located at wind power generation stepped impeller lower section, is arranged on
On tower wall 5, including train wheel bridge 6, lower plate 7, pressing plate 9 and bolt 8.Wherein, train wheel bridge 6 and the thickness of lower plate 7 are slightly less than pre-
The diameter of stress drag-line 2, is fitted on tower wall 5 by bolt 8, forms duct 10, and prestressed cable 2 is arranged on duct 10
Interior, pressing plate 9 is covered on train wheel bridge 6 and lower plate 7 and prestressed cable 2, prestressed cable 2 is applied by bolt 8 press
Power, so as to produce frictional force to avoid drag-line 2 from being slided in duct 10.Because prestressed cable 2 is not by wind power generation stepped tower 1
Kernel of section, therefore, in addition to providing anti-side rigidity for tower, also provide torsional rigidity.
It is finally noted that, the purpose for publicizing and implementing example is that help further understands the present invention, the skill of this area
Art personnel should be recognized that：Without departing from the spirit and scope of the invention and the appended claims, various substitutions and modifications are all
It is possible.Therefore, the present invention should not be limited to embodiment disclosure of that, and the scope of protection of present invention will with right
The scope for asking book to define is defined.
