Fruit is good, moreover it is possible to which the rotation energy for accelerating consumption transmission shaft allows transmission shaft comparatively fast to stop and a power.Allow the rotatory force of annulus block
The transmission path occupied area being transmitted on propeller is small, and dynamic convenient for propeller driving cooling liquid stream, cooling liquid flow effect is good,
So that cooling-down effect might as well.
Embodiment 5, shown in Figure 18-Figure 21.Embodiment 5 and the difference of embodiment 1 are as follows：
A kind of automatic tripping system of steam turbine mechanical overspeed trip device further includes rotating inflatable body in advance；And in one kind
Steam turbine mechanical overspeed trip device automatic tripping system rotates inflatable body in advance when slowing down can be pressed into contact with company in friction plate
Annulus block is connected on to go forward that annulus block is driven to rotate towards the direction that friction plate rotates in advance.
Preceding rotation inflatable body includes high pressure air blowing machine 76,77, No. two high-pressure air pipes 86 of No.1 high-pressure air pipe, annulus air blowing
Mouth 85, annulus exhaust nozzle 88,92, No. two reinforcing bars 87 of No.1 reinforcing bar, No.1 sliding bar 84, No.1 pipe 79, the free bullet of No.1
The normally opened pressure switch 82 of spring 78, No.1 pressing plate 81, No.1, the normally closed pressure switch 91 of No.1 and fixed block 83；Fixed block is fixed on
On the shell of annulus plunger shaft, the right output port of No.1 pipe is fixedly connected on the left surface of fixed block, the left end of No.1 sliding bar,
The free spring of No.1 and No.1 pressing plate are all moveably positioned in the tube chamber 80 of No.1 pipe respectively, and the normally opened pressure switch of No.1 is fixed on
In the tube chamber of the No.1 pipe of No.1 pressing plate right, the right end of No.1 sliding bar is fixedly connected on the annulus outside annulus plunger shaft
On piston, the both ends of the free spring of No.1 are respectively fixedly connected on the left side of No.1 sliding bar and the left surface of No.1 pressing plate
On；The normally closed pressure switch of No.1 is fixed in the left port of No.1 pipe, is equipped with by a No. two free bullets on No.1 sliding bar
No. two pressing plates 90 that spring 93 connects, and No. two pressing plates are slidably connected with No.1 sliding bar；It is pressed into contact with and if only if friction plate
No. two pressing plates, which will compress, when being connected on annulus block is connected in the normally closed pressure switch of No.1, and the normally closed pressure of No.1 at this time
Power switch can be just off；The normally opened pressure switch of No.1 and the normally closed pressure switch of No.1 are all connected in series in high pressure air blowing
On 95 circuit 96 of power supply of machine；Left annulus air blowing region band 94 is equipped on the left surface of annulus block, on the right surface of annulus block
It is equipped with right annulus air blowing region band；The right side for being laid with several and annulus block is taken in the left annulus air blowing region of annulus block
The wind drive ventilation hole 89 that annulus air blowing region band is connected；Annulus blowing nozzle is fixedly connected on stator by No.1 reinforcing bar
On, and annulus blowing nozzle is arranged with left annulus air blowing region face gap；Annulus exhaust nozzle is fixed by No. two reinforcing bars to be connected
It is connected on stator, and annulus exhaust nozzle is arranged with right annulus air blowing region face gap；High pressure air blowing machine is fixed on outside stator,
The both ends docking of No.1 high-pressure air pipe is connected on the inlet end of annulus blowing nozzle and on the outlet side of high pressure air blowing machine, No. two height
One end docking of air pipe is connected on the exhaust end of annulus exhaust nozzle, and the other end of No. two high-pressure air pipes is fixed on outside stator.
When a kind of automatic tripping system of steam turbine mechanical overspeed trip device will slow down, annulus piston is past to move right drive one
For the left end of number sliding bar also toward moving right, the left end of No.1 sliding bar drives the free spring of No.1 and No.1 pressing plate toward moving right
Toward moving right, No.1 pressing plate, which can be pressed on toward moving right after in the normally opened pressure switch of No.1, allows the normally opened pressure switch of No.1 in closing
Conjunction state；After the normally opened pressure switch of No.1 is closed, the electric power loop of high pressure air blowing machine is in closed state, high pressure air blowing at this time
Machine energization starts work immediately；The high pressure draught of high pressure air blowing machine blowout passes sequentially through No.1 high-pressure air pipe, annulus blowing nozzle, wind
It is discharged after power drive ventilation hole, annulus exhaust nozzle and No. two high-pressure air pipes；Pass through circle in the high pressure draught of high pressure air blowing machine blowout
When the wind drive ventilation hole of ring block, high pressure draught can push annulus block to be rotated towards the direction that friction plate rotates, and rub
Piece be pressed into contact be connected to annulus block go forward high pressure draught in advance pushed annulus block rotate；When friction plate is pressed into contact with connection
Since the normally closed pressure switch of No.1 disconnects the electric power loop of high pressure air blowing machine is off when on annulus block, high pressure
Hair-dryer power-off is stopped immediately.
The embodiment of this practicality is described above in conjunction with attached drawing, however, the implementation is not limited to the above embodiments, this field
Those of ordinary skill can be with various changes and modifications may be made within the scope of the appended claims.
