As shown in fig. 1-4, when the device of the present invention is in the initial state, the spur gear 69 is not meshed with the blade gear 25, the transposition gear 50 is not meshed with the spur gear 52, the transposition gear 50 is not meshed with the pulley gear 13, the seal contact block 18 is in contact with the trigger block 24, and the secondary magnetic plate spring 35 is in the stretched state;

sequence of mechanical actions of the whole device:

when the steam pipeline starts to work, after liquid water enters the steam pipeline, the temperature in the steam pipeline is rapidly reduced, the temperature in the steam pipeline 23 is reduced to enable the liquid in the heat sensing liquid cavity 17 to contract, so that the sealing contact block 18 moves leftwards, the sealing contact block 18 moves leftwards and drives the main magnetic block 32 to move rightwards by overcoming the pulling force of the elastic pulling rope 31 through the main magnetic block pulling rope 74, meanwhile, the sealing contact block 18 is separated from being in contact with the trigger block 24, the trigger block 24 sends out a signal to enable the motor 11 to start to rotate, the motor electromagnet 46 is electrified, the absorption motor magnet 44 moves leftwards by overcoming the thrust of the motor magnet spring 45, the motor magnet 44 moves leftwards and drives the transposition gear 50 to move leftwards through the transposition transmission shaft 49 to be meshed with the line gear 13, the motor 11 rotates to drive the transposition transmission shaft 49 to rotate through the motor shaft 47, the transposition transmission shaft 49 rotates, the pulley gear 13 rotates to drive the pulley 14 to rotate through the pulley shaft 12, the pulley 14 rotates to pull the magnetic resistance plate stopper 40 to move rightwards by overcoming the thrust of the magnetic resistance plate spring 42 through the pulley pull rope 15, and therefore the magnetic resistance plate 73 moves rightwards;

at the moment, the rightward movement speed of the magnetic resistance plate 73 is smaller than the rightward movement speed of the main magnetic block 32, so that the main magnetic block 32 can be blocked by the magnetic resistance plate 73, the main magnetic block 32 does not adsorb the auxiliary magnetic plate 34, the auxiliary magnetic plate 34 moves upwards under the action of the tension of the auxiliary magnetic plate spring 35 to correspond to the auxiliary magnetic cavity 37, the auxiliary magnetic plate 34 adsorbs the auxiliary magnet 38 to move leftwards, the auxiliary magnet 38 moves leftwards, pulls the sealing plate 20 to move rightwards to open the pressure relief cavity 19 by overcoming the thrust of the sealing plate spring 21 through the auxiliary magnet pull rope 39, and simultaneously pulls the sealing block 27 to move leftwards to open the water outlet cavity 28 by overcoming the thrust of the sealing block spring 29, the vacuum environment in the steam pipeline is damaged, and all the water drainage channels are opened to drain water;

after a period of time, the motor electromagnet 46 is de-energized, the transposition gear 50 is reset under the elastic force of the motor magnet spring 45, the magnetic resistance plate 73 is reset under the elastic force of the magnetic resistance plate spring 42, the transposition electromagnet 43 is energized after the motor electromagnet 46 is de-energized, the adsorption transposition magnet 54 moves leftwards against the thrust of the transposition magnet spring 53, the transposition magnet 54 moves leftwards and drives the transposition shaft 61 to move leftwards through the transmission spur gear 52, so that the transmission spur gear 52 is meshed with the transposition gear 50, the transposition shaft 61 moves leftwards and drives the transmission spur gear shaft 70 to move leftwards through the centrifugal block 71, so that the transmission spur gear 69 moves leftwards to be meshed with the blade gear 25, at the moment, the transposition gear 50 rotates and drives the transposition shaft 61 to rotate through the transmission spur gear 52, the transposition shaft 61 rotates and drives the convex shaft wheel 60 to rotate, the convex shaft 60 rotates and drives the centrifugal block 71 to rotate under the limit that the convex shaft 57 is abutted to, the centrifugal block 71 rotates to drive the spur gear 69 to rotate through the spur gear shaft 70, and the spur gear 69 rotates to drive the blade shaft 26 to rotate through the blade gear 25, so that the turbine blade rotates;

when the liquid water in the steam turbine is completely discharged, the steam turbine blade can be easily rotated, namely the convex shaft wheel 60 can drive the centrifugal block 71 to rotate, the centrifugal block 71 rotates, the main contact block 66 overcomes the pulling force of the main contact block spring 67 to move outwards to be contacted with the contact buzzer 64 due to the centrifugal action, at the moment, the motor 11 stops rotating, the transposition electromagnet 43 is powered off, the transmission straight gear 52 is reset, the steam turbine can work again, meanwhile, the temperature in the steam pipeline gradually rises, so that the sealing contact block 18 is contacted with the trigger block 24, the main magnetic block 32 can adsorb the auxiliary magnetic plate 34 to move downwards to be corresponding to the auxiliary magnet cavity 37 by overcoming the pulling force of the auxiliary magnetic plate spring 35, then the sealing plate 20 is reset under the elastic force of the sealing plate spring 21, and the sealing block 27 is reset under the elastic force of the sealing block spring 29, so that the interior of the steam pipeline is in a vacuum state again;

when the liquid water in the steam turbine may not be completely discharged, the steam turbine blade cannot be easily rotated, that is, the protruding shaft wheel 60 cannot drive the centrifugal block 71 to rotate, the main contact block 66 cannot contact with the contact buzzer 64, and the contact buzzer 64 is not contacted for a long time after the transposition electromagnet 43 is electrified, so that an alarm can be given out to remind a worker to maintain.

The invention has the beneficial effects that: this device judges the change of the inside temperature of steam conduit because of water hammer through the liquid expend with heat and contract with cold of hotness liquid intracavity, reduce rapidly as the temperature, take place the water hammer condition promptly, then open the pressure release chamber and go out the water cavity and remove steam conduit's vacuum environment and the inside liquid water of discharge steam conduit, can in time carry out urgent processing to the steam turbine, avoid the steam turbine to be damaged, on the other hand, whether light judge water hammer phenomenon serious through rotating the blade, then make and correspond the processing, avoid the less problem also to carry out the complex operation of investigation on a large scale.
