[0026] like Figure 1 As shown, the present application provides a rotary monitoring tool capable of regulating oil temperature, comprising a storage cylinder 1, and a sealing assembly 2 is arranged on the storage cylinder 1, and the sealing assembly 2 is used to seal the storage cylinder 1;

[0027] like Figure 1 As shown, the sealing assembly 2 includes a sealing cover 21 detachably mounted on the storage cylinder 1, and a sealing gasket (not shown in the figure) is provided at the connection between the sealing cover 21 and the storage cylinder 1, so as to seal the storage cylinder 1, and two sets of lifting ears 22 are provided on the sealing cover 21, and the lifting ears 22 are made of high temperature resistant material, such as stainless steel or high temperature resistant alloy steel, so as to facilitate the storage cylinder 1 to be taken in and out in a high temperature or low temperature environment;

[0028] At the same time, a venting solenoid valve 23 and a button 24 are respectively provided on the sealing cover 21. The venting solenoid valve 23 is electrically connected to the button 24 to control its opening and closing, so as to ventilate or seal the interior of the storage cylinder 1, so as to simulate the test of the rotary transformer in the ventilated state;

[0029] At the same time, a lifting and placing component 3 is provided on the sealing component 2, and the lifting and placing component 3 is used to lift and place the rotary transformer;

[0030] like Figure 1-Figure 3 As shown, the lifting assembly 3 includes a lifting rod 31 (sealed) penetrating the sealing cover 21, and a placement plate 33 is fixedly installed at one end of the lifting rod 31 to facilitate the placement of the rotary transformer. The placement plate 33 is located inside the storage cylinder 1. It should be noted that the other end of the lifting rod 31 is connected to the cylinder (not shown in the figure). Driven by the cylinder, the lifting rod 31 drives the placement plate 33 to move up and down in the storage cylinder 1, and synchronously drives the rotary transformer placed on the placement plate 33 to move up and down;

[0031] At the same time, a connecting pipe 34 is inserted into the storage cylinder 1, and an oil plug 32 is detachably installed at one end of the connecting pipe 34 away from the storage cylinder 1, so that when it is necessary to monitor the resolver in the power-on state, the oil plug 32 is opened and the wiring harness of the resolver on the placement plate 33 is led out through the connecting pipe 34;

[0032] At the same time, a temperature control component 4 is provided on the storage cylinder 1, and the temperature control component 4 is used to increase or decrease the temperature of the storage cylinder 1;

[0034] When the storage cylinder 1 needs to be kept at a constant temperature, hot air or cold air is introduced into the coil through the air inlet 41 and led out of the coil from the air outlet 43. In this process, the coil heats up or cools down the base 42 through the hot air or cold air, thereby simultaneously heating up or cooling down the storage cylinder 1.

At this time, oil is injected into the storage cylinder 1, and the resolver is placed on the lifting and placing component 3. At this time, the resolver is not energized, and the sealing component 2 and the storage cylinder 1 are sealed and installed. The lifting and placing component 3 drives the resolver to descend until the resolver is immersed in the oil.
