Example two

Referring to fig. 6, in a first comparative example, as another embodiment of the present invention, a spring 9 is fixed to the top of the control rod 34; the top end of the spring 9 is fixedly connected with the inner side wall of the top of the switch box 13; the end part of the sealing valve block 112 is fixedly connected with a rubber cushion block 91; the position of the rubber cushion block 91 corresponds to that of the ejector rod 18; by providing a spring 9 on top of the lever 34; when the control rod 34 is stationary, the switch box 13 is in a stable state, and the movement phenomenon cannot easily occur, and meanwhile, the rubber cushion block 91 is arranged at the end part of the sealing valve block 112, so that when the push rod 18 pushes against the sealing valve block 112, the damage caused by the impact of the push rod 18 and the sealing valve block 112 can be reduced.

The working principle is as follows: when in use, the position of the sealing valve block 112 and the sounding vent pipe 111 is set to be in a dislocation state, then the elastic sealing gasket 17 is in a contraction state in the oval piston cylinder 15, and the hollow heat conducting pipe 12 is tightly attached to the side wall of the transformer body 1, then heat is generated in the using process of the transformer body 1, meanwhile, a large amount of heat is generated in the long-time high-load use of the transformer body 1, when the heat is not in time to be dissipated, a large amount of heat energy is gathered in the inner part and the wall body of the transformer body 1, at the moment, the gas in the hollow heat conducting pipe 12 is excessively expanded by heat, when the heat heats the gas, the expansion pressure of the gas cannot reach enough to prop open the elastic sealing gasket 17, the ejector rod 18 cannot move in the oval piston cylinder 15, then when the temperature of the transformer body 1 is higher, the gas pressure in the hollow heat conduction pipe 12 will push the elastic sealing gasket 17 open, so that the push rod 18 pushes towards the direction of the sealing valve block 112, then the sealing valve block 112 is pushed into the sounding ventilation pipeline 111, so that the gas in the high-pressure gas tank 19 will be discharged to the outside of the control box 11 through the sounding ventilation pipeline 111, while the sounding ventilation pipeline 111 exhausts, the gas flow will impact the vibrating plate 113, so that the vibrating plate 113 vibrates, and then sounds are emitted, warning the personnel near the transformer body 1, the heat of the transformer body 1 is too high, it is necessary to pay attention, the transformer body 1 is temperature-sensed by the joint of the hollow heat conduction pipe 12 and the transformer body 1, and the gas at the blowing position of the high-pressure gas tank 19 controls the switch box 13 to vibrate, the overload alarm of the transformer can be realized, and the process is completely realized through the mechanical structure, and has higher stability compared with the electronic components, the stability in use is also improved, and the problem of failure is not easy to occur. Through being equipped with first magnetite 2 and the inside second magnetite 21 of control box 11 in sealed valve block 112 inside and cooperating, can not withstand sealed valve block 112 when ejector pin 18, make sealed valve block 112 keep the position of dislocation constantly in sound production air duct 111 inside, make sealed valve block 112 at the in-process of stewing, can not slide to sound production air duct 111 inside, and then the false alarm problem appears, the accuracy of whole device to overload warning has been promoted. Through the cover has the standpipe 3 on hollow heat pipe 12, can be when the temperature of hollow heat pipe 12 and transformer body 1 reaches the temperature that makes the water boiling, the inside liquid of steam box 31 will gasify in a large number, and then will seal the flexible pad 33 and open in the inside top of steam box 31, make ejector pin 18 can normally push up sealed valve block 112, this standpipe 3 is inside can fill into the different liquid of boiling point, can realize the temperature alarm control of different height when transshipping transformer body 1, can realize transshipping the warning to transformer body 1 of different service environment. Through being equipped with apron 41 in steam box 31 inside and block control the vapor of steam box 31 bottom, can be when steam box 31 inside steam is more, sealed flexible pad 33 just can be by jack-up, and then make ejector pin 18 push up sealed valve block 112 through control lever 34, this setting can make sealed flexible pad 33 when the inflation, there is higher ejecting dynamics, avoid when ejector pin 18 has already pushed up the lateral wall of control lever 34, sealed flexible pad 33 can not normally expand, and the unable normal phenomenon of pushing up sealed valve block 112 of ejector pin 18 that leads to, further increase stability and the security of whole device when using. Through the mutual adsorption of third magnet 5 and fourth magnet 51, can be in the in-process of using, make the top that is adsorbed at supporting shoe 4 of apron 41 tightly, when making the atmospheric pressure of apron 41 bottom great, just can jack up apron 41, then make steam push up sealed flexible pad 33, make its sudden expansion, then make ejector pin 18 can normally pass control lever 34, impact seal valve piece 112, make the inside gas of high-pressure gas pitcher 19 discharge from vocal breather pipe 111, impact vibrations piece 113 vibrates, warn personnel around transformer body 1. Be equipped with flexible sealing strip 61 through apron 41 lateral wall, and stretch into inside sealed hole 6, can make apron 41 by during the jack-up, high-pressure gas still need be higher than the height at sealed hole 6 top with the height of apron 41 jack-up, make flexible sealing strip 61 pulled out from the inside of sealed hole 6, then just have gas impact to sealed flexible pad 33, and then increase the effect of the removal dynamics of control lever 34, realize that control lever 34 can be in the inside normal removal of control box 11. Through being equipped with the flexible arc strip 7 of multiunit at the lateral wall of flexible sealing strip 61, multiplicable sealed hole 6 is at the inside gas tightness of sealed hole 6, reduce gaseous from the inside unexpected exhaust problem of sealed hole 6, when making transformer body 1's high temperature, increase inside steam box 31, the atmospheric pressure of apron 41 bottom grows high speed, make high-pressure gas strike the dynamics of sealed flexible pad 33 increase, dynamics when also having increased control lever 34 simultaneously and removing. Through being equipped with anticreep J-shaped strip 8 and anticreep piece 81 in the both sides of sealing valve block 112, can be when sealing valve block 112 is static, sealing valve block 112 can not break away from the inside of vocal vent pipe 111, and when ejector pin 18 withstood sealing valve block 112, can not ejecting sealing valve block 112 outside vocal vent pipe 111, and then the stability of multiplicable sealing valve block 112 in vocal vent pipe 111 is inside, has also promoted the job stabilization nature of whole device simultaneously. By providing a spring 9 on top of the lever 34; when the control rod 34 is stationary, the switch box 13 is in a stable state, and the movement phenomenon cannot easily occur, and meanwhile, the rubber cushion block 91 is arranged at the end part of the sealing valve block 112, so that when the push rod 18 pushes against the sealing valve block 112, the damage caused by the impact of the push rod 18 and the sealing valve block 112 can be reduced.
