Description
Technical field:
The utility model relates to one kind to be suitable for huge pumped-storage power generation machine fixed wind sheild new structure.
Background technique:
Traditional fixed wind sheild structure can not accomplish that complete wind path recycles for the cooling of storage generator air, due to magnetic yoke
Upper end does not have vertical wind deflector to make wind by that can not pass through stator completely when air gap between generator stator and rotor, due to wind pressure
The reason of very Wind Volume can be lost from magnetic yoke upper end, drafting efficiency is very poor, generally require increase intake volume just can overcome the disadvantages that.Tradition
After mounting, for outer circle side block above air gap, unit is unable to measure air gap, tradition gear in maintenance to wind deflector without tearing wind deflector open
The bracket of aerofoil can be only installed at below upper bracket-arm the position for being limited to support arm and number, and installation and design are all more numerous
It is trivial, it is badly in need of a kind of suitable for huge pumped-storage power generation machine fixed wind sheild new structure.
Summary of the invention:
The purpose of this utility model is to promote generator by huge pumped-storage power generation machine fixed wind sheild new structure
Drafting efficiency improves cooling effect in turn, and the air quantity of loss can be effectively reduced by increasing the vertical wind deflector in magnetic yoke upper end.This is practical
Novel technical solution are as follows: by vertical wind deflector (1), wind deflector (2), rigidity hanger (3), stay bolt (4), air gap wind deflector
(10), attachment base (12) and pressing plate (13) composition, wind deflector (2), air gap wind deflector (10) pass through stay bolt (4) and pressing plate (13)
It is assembled on attachment base (12), rigidity hanger (3) is hung in upper spider lower end, is hung attachment base (12) with rigidity with stay bolt (4)
Connection is closed, vertical wind deflector (1) is welded on magnetic yoke upper end and close to wind deflector (2) frame (3).
The vertical wind deflector (1) is by gusset (5), vertical plate (6), insulation board (7), stud (8) and lag bolt (9) group
At insulation board (7) and stud (8) are assembled on vertical plate (6) by lag bolt (9).
The wind deflector (2) is made of right-angled glass steel plate (11), insulation softwood matter (15), insulation softwood matter (15) peace
Mounted in the inner circle side of right-angled glass steel plate (11).
The rigidity hanger (3) is by ring flat-plate (16), base plate (17), bolt (18), channel steel (19) and plywood
(20) form, base plate (17), channel steel (19), plywood (20) are organized it is integral, by bolt (18) will ring flat-plate (16) with it is basic
Plate (17) connects conjunction.
The air gap wind deflector (10) is made of obtuse angle glass epoxy (14), insulation softwood matter (15), and insulate softwood matter
(15) it is mounted on the inner circle side of obtuse angle glass epoxy (11).
Working principle:
At runtime, cooling wind will receive the influence of negative pressure to pumped storage machine when entering stator by air gap, from
The evolution of magnetic yoke upper end installs vertical wind deflector in magnetic yoke upper end and keeps suitable gap with wind deflector, can generate here than it is fixed,
The bigger wind pressure of air gap between rotor forces cooling wind track to must open into stator and finally enters aerial cooler.New structure
Hanger structure is improved, has been modified to ring flat-plate welding with upper spider welding, it in this way can basis in mounting suspension
The position needed, which attaches together the base plate of hanger with ring flat-plate progress handle, matches, and such design is more reasonable, and installation is also easier, and
Plywood is also made that improvement connecting with wind deflector by hanger, and wind deflector is clipped in the middle by pressing plate and attachment base connects plywood
It connects, in this way it is avoided that processing the hidden danger of screw thread on glass reinforced plastic, novel connection structure is firmer, dismantles also more flexible.
Technical effect:
Magnetic yoke upper end adds vertical wind deflector to be the principle for being greater than air gap wind pressure by reinforcing the wind pressure of wind deflector, is promoted effective
Air quantity so that improve cooling effect；The installation controllability for optimizing air gap wind deflector and wind deflector is more convenient for measuring and determines, turns
Air gap between son and the installation gap convenient for control and vertical wind deflector；Again by improving the structure of rigidity hanger, so that
Design, installation and removal are all easier；The type of attachment of wind deflector and hanger is even more greatly superior connection mould in the past
Formula.The new structure of huge pumped-storage power generation machine fixed wind sheild not only greatly promotes performance of ventilating, and from entirety
Safety, operation, the design of structure have all carried out great Optimal improvements.
