Description
Technical field
Technical field of wind power generation is the utility model is related to, specifically, designs a kind of only opening for tower of wind generating set tube door
Structure.
Background technology
In wind generator system, electric power facility and the cat ladder for being constructed and being safeguarded are generally disposed at generator pylon
In cylinder, enter for ease of operating personnel in pylon and the other equipment in electric power facility and electricity generation system is maintained and tieed up
Shield, is generally provided with tower door on pylon shell ring.
Tower door is in lockup state in operation, also prevents layman from being strayed into tower while playing anti-theft effect
Cylinder；During maintenance, tower door is in released state and can freely opened, but because Wind turbines are often in wind-force
Larger region, when producing instantaneous high wind the tower door of non-locking can throw open, the personnel near tower door are made
Into potential safety hazard.If disengaging tower door is all locked a door every time, undoubtedly inconvenience is brought to maintenance process.
In view of this, it is special to propose the utility model.
Utility model content
The utility model provides a kind of only opening structure of tower of wind generating set tube door, using safe band connection tower Men Yuta
Barrel, instantaneous high wind is avoided to make tower door body throw open so as to cause the purpose of security incident to reach.
To achieve the above object, the utility model specifically adopts the following technical scheme that：
A kind of tower of wind generating set tube door stops opening structure, and only opening structure is used for the door body 6 and tower of Wind turbines tower
Wall is connected, and the only opening structure includes safety belt 1, the coiler 2 of folding and unfolding safety belt 1 is used for located at tower wall and is fixed on tower
Being detachably connected around belt wheel 3, the safety belt 1 through being connected around belt wheel 3 with coiler 2 with door body 6 for barrel, makes door
Body 6 is remained off when being acted on by transient force by the traction of safety belt 1.
In such scheme, coiler 2 is by circular take-up spool and at least one solid for the part of the sensing acceleration of safety belt 1
Dingan County is formed mounted in the ratchet of the shaft end.The circular take-up spool is movably through the ellipse of winding storehouse both sides mainboard
In axis hole, the oblique upper of the oval axis hole is provided with interior ratchet on the inside of mainboard, and it forms locking component with the ratchet.Peace
Full band 1 is made up of the synthetic fibers of intensity maximum, and after door body 6 and tower wall are connected into safety belt 1, coiler 2 is automatically by it
Tense, when door body 6 is had unlatching trend by instantaneous wind-force, safety belt 1 can be made to be furled this moment by quick and fierce stretching
The auto-lock function of device 2 can block safety belt 1 in moment, remain off door body.Application is not interfered with simultaneously continues thrust
Door opening action.
It is of the present utility model further scheme be：The door body 6 is rotarily opened with door-hinge 7 for hinge, the only opening structure
It is arranged at the side opposite with the opening direction of door body 6, the coiler 2 and the tower wall that door-hinge 7 is disposed in proximity to around belt wheel 3
On.
In such scheme, blower fan tower barrel door is typically opened to outside tower, therefore only opening structure is arranged on tower inwall, with tower
Door be connected towards the one side on the inside of tower, prevent environmental change and artificial destruction be losts to caused by stopping opening structure, also beneficial to pair
The only maintaining of opening structure.
It is of the present utility model further scheme be：The only opening structure also includes the buckle 4 on safety belt 1, described
Door body 6 is provided with the deck 5 that is engaged with buckle 4, makes safety belt 1 realize and is detachably connected with door body 6.
It is of the present utility model further scheme be：The deck 5 be arranged at away from door-hinge 7 and with the opening direction of door body 6
In the door body 6 of opposite side.
In such scheme, because blower fan tower barrel door is frequently with single fan flush door structure, therefore acted on by instantaneous high wind
When, the part away from door-hinge 7, which is most susceptible to transient force effect, in door body 6 makes door body 6 open suddenly, therefore will be used to only to open
The deck 5 that structure is fixed on door body 6 is arranged in the door body 6 away from door-hinge 7, makes tower door be not easy to be acted on unlatching by transient force.
It is of the present utility model further scheme be：The deck 5 is located at the top and/or middle part and/or bottom of door body 6.
It is of the present utility model further scheme be：Provided with the only opening structure corresponding with the position of the deck 5, the card
The only opening structure corresponding with position of seat 5 is connected, and makes safety belt 1 be arranged in parallel.
It is of the present utility model further scheme be：Provided with the only opening structure corresponding with the position of the deck 5, the card
Seat 5 is connected with the only opening structure being staggeredly located out makes safety belt 1 set at an angle to the horizontal direction.
In such scheme, deck 5 away from door-hinge 7 set on the basis of, can be respectively arranged on door body 6 upper, middle and lower portion or
Combination settings set in upper, middle and lower portion and stop opening structure with the quantity identical of deck 5, only the card of opening structure and correspondence position
When seat 5 is connected, safety belt 1 can equably undertake the effect of transient force parallel to horizontal direction；Only opening structure and non-corresponding position
When the deck 5 put is connected, safety belt 1 enhances leading to door body 6 due to arranged in dislocation formation and the certain angle of horizontal direction
Drawing acts on, and under stronger transient force effect door body 6 can be kept to close.
It is of the present utility model further scheme be：It is described only opening structure also include in vertical direction be located at around belt wheel 3
The fixator 8 of diverse location；Through being connected around belt wheel 3 with coiler 2, the other end is connected with fixator 8 for described one end of safety belt 1
Connect；The buckle 4 is slided along safety belt 1 and set.
In such scheme, safety belt is fixed on fixator 8 through buckle 4, makes buckle 4 be slided on safety belt and sets
To put, the deck 5 that can correspond to diverse location is attached, and upon connection, door body is pulled by two sections of safety belts 1, with
Tackle larger instantaneous wind-force.
It is of the present utility model further scheme be：Described one end of safety belt 1 is another through being connected around belt wheel 3 with coiler 2
End is connected with buckle 4；When buckle 4 is connected with deck 5, makes safety belt 1 apply door body 6 and only open resistance.
It is of the present utility model further scheme be：The door body 6 is additionally provided with door lock, and the door lock is formed with deck 5 and interlocked
Structure, when door lock locking, deck 5 is separable with buckle 4；When door lock is opened, deck 5 can not separate with the phase locking of buckle 4,
