Description
Technical field
The invention belongs to tower technical fields, and in particular to a kind of blower fan tower barrel with urgent offloading functions.
Background technique
In recent years, China's Wind Power Generation Industry is fast-developing, and high-power, super high power blower is constantly introduced to the market.With blower
The continuous increase of power, blower fan tower barrel height are also continuously increased, and rise to 150m from the 40m of early stage, tower type is also from rigid
Property tower development be tower semi-flexible and flexible tower.In order to guarantee that tower can safely and reliably work, the intensity of tower is not only
Meet load requirements when blower works normally, but also to meet the load requirements under extreme operating condition.Existing blower tower
Cylinder goes to meet the load requirements under extreme operating condition from the angle for improving intensity mostly, and the weight that will lead to tower so substantially increases
Add, manufacturing cost is also obvious therewith to be risen.In fact extreme operating condition seldom occurs, even if occurring, blower also can not be in normal
Work the state to generate electricity, and it can be considered to be solved the above problems by the angle for improving blower fan tower barrel structure.
Summary of the invention
The technical problem to be solved in the present invention is to overcome the shortcomings of the prior art, provides that a kind of structure is simple, weight
Gently, the low blower fan tower barrel of manufacturing cost, which can actively reduce the load of receiving in extreme operating condition, in nominal situation
When will not reduce the absorption efficiency of wind energy again.
In order to solve the above technical problems, technical solution proposed by the present invention are as follows:
A kind of blower fan tower barrel with urgent offloading functions, including tower ontology, the tower ontology, which is equipped with, laterally to be passed through
The unloading air duct of the tower ontology is worn, the inlet in the unloading air duct, which is equipped with, is generally in closed state and in certain wind load
The lower portal activity air door that can be automatically opened of effect, the exit in the unloading air duct, which is equipped with, is generally in closed state and one
Determine the lower outlet activity air door that can be automatically opened of wind load effect.When ambient wind velocity is greater than the Limit of Wind Speed that blower fan tower barrel allows to run
When, portal activity air door and outlet activity air door are automatically opened the conducting of unloading air duct under wind load effect to realize unloading,
When ambient wind velocity restores from Limit of Wind Speed to normal wind speed, portal activity air door and outlet activity air door restore to common pass
Closed state, unloading wind-tunnel are automatically closed, and blower fan tower barrel restores to work normally, and in nominal situation, blower fan tower barrel will not be reduced
The absorption efficiency of wind energy.
Above-mentioned blower fan tower barrel, it is preferred that the inlet in the unloading air duct, which is equipped with, limits the portal activity air door only
The entrance limited block that can be opened towards a direction, the exit in the unloading air duct is equipped with the limitation outlet activity air door can only
The outlet limited block opened towards direction identical with portal activity air door opening direction.Entrance limited block and outlet limited block can
Limitation portal activity air door and outlet activity air door are opened in same direction, are guaranteed under certain wind load, portal activity air door
Outlet activity air door can be opened conducting unloading air duct rapidly by wind load after opening, simultaneously for convertible portal activity air door and
Outlet activity air door, entrance limited block and outlet limited block can prevent portal activity air door and outlet activity air door from making in wind load
Under it is irregular overturning or one open a conjunction movement, avoid its influence unloading air duct unloading effect.
