[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figures 1-7 As shown, one of the objectives of this embodiment is to provide a novel sealing oil injection mechanism, including an oil storage tank 1. A top cover 11 is sealed to the top of the oil storage tank 1, forming a chamber for storing sealing oil. This chamber is connected to the outside air through the top cover 11. An end cap 12 is sealed to the top of the top cover 11, and an oil inlet pipe 121 is fixedly mounted on the end cap 12. The lower end of the oil inlet pipe 121 extends to the bottom of the oil storage tank 1, leaving a gap between the bottom end of the oil inlet pipe 121 and the bottom of the oil storage tank 1, so that the sealing oil in the oil storage tank 1 can enter the oil inlet pipe through the gap. In section 121, the inner wall of the oil inlet pipe 121 is provided with a cavity for placing the heating wire 123. The spiral heating wire 123 is fixedly installed inside the oil inlet pipe 121, that is, the heating wire 123 is placed in the cavity, and the cavity extends through the top of the oil inlet pipe 121. When installing the heating wire 123, the heating wire 123 is inserted into the inside of the oil inlet pipe 121 through the cavity, and then the top of the cavity is sealed with a plug. When the heating wire 123 is working, it generates heat to melt the solidified sealing oil. The end cap 12 is fixedly installed with a control device. The heating wire 123 is connected to the controller, and the controller controls the operation of the heating wire 123.

[0024] Several heat-conducting rings 122 are fixedly installed on the oil inlet pipe 121 along the axial direction of the oil inlet pipe 121. When the sealing oil inside the oil storage tank 1 solidifies, the controller controls the heating wire 123 to generate heat. The heat generated by the heating wire 123 is transferred to the heat-conducting rings 122 through heat conduction. Then, under the conduction of the heat-conducting rings 122, the heat generated by the heating wire 123 is quickly diffused into the interior of the oil storage tank 1, so that the heat heats the sealing oil and melts it into a liquid state, so that the operator can inject the liquid sealing oil into the equipment.

[0025] To improve the heating effect of the heating wire 123 on the sealing oil inside the oil storage tank 1, a stirring mechanism 3 is provided inside the top cover 11. The stirring mechanism 3 is used to stir the sealing oil, so that the sealing oil in the oil storage tank 1 is mixed and stirred. At this time, the sealing oil heated by the heat conduction ring 122 is transferred to other places, while the unheated sealing oil comes into contact with the heat conduction ring 122, thereby accelerating the heating effect of the sealing oil.

[0026] The top cover 11 has an installation groove 111 inside, and the lower surface of the top cover 11 has an annular rotating groove 112 that communicates with the installation groove 111. The stirring mechanism 3 includes a rotating ring 31 rotatably connected inside the rotating groove 112. Several rotating rods 32 are rotatably connected to the center of the rotating ring 31. This solution only shows the case of two rotating rods 32. The rotating ring 31 drives the rotating rods 32 to rotate. At the same time, the lower end of the rotating rods 32 extends to the bottom of the oil storage tank 1. Several stirring rods 321 are fixedly installed on the side wall of the rotating rods 32. The stirring rods 321 have sharp rhomboid sides. The rotating rods 32 drive the stirring rods 321 to rotate, so that the stirring rods 321 stir the sealing oil. When the rhomboid stirring rods 321 rotate, they can quickly separate the solidified sealing oil, thus accelerating the stirring effect of the stirring mechanism 3 on the sealing oil.

[0027] Meanwhile, a motor 34 is fixedly installed on the upper surface of the top cover 11. The output shaft of the motor 34 extends into the interior of the mounting groove 111 and is coaxially connected to a second gear 341 via a coupling. During rotation, the output shaft of the motor 34 drives the second gear 341 to rotate. A first gear ring 311 is fixedly installed on the inner arc sidewall of the rotating ring 31. The second gear 341 and the first gear ring 311 mesh. The rotating second gear 341 drives the first gear ring 311 and the rotating ring 31 to rotate. The rotating ring 31 rotates in the rotating groove 112. At the same time, the upper end of the rotating rod 32 extends into the interior of the mounting groove 111 and is coaxially fixedly installed with a first gear 322. A second gear ring 33 is fixedly installed on the lower surface inside the mounting groove 111. The second gear ring 33 is coaxially sleeved on the outside of the rotating ring 31. The second gear ring 33 and the rotating ring 31 do not contact each other. The first gear 322 meshes with the second gear ring 33. During the process of heating and melting the solidified sealing oil by the heating wire 123, the output shaft of the rotating motor 34 drives the first gear 341 to rotate. The second gear 341 rotates, and during its rotation, the second gear 341 drives the rotating ring 31 to rotate via the first gear ring 311. The rotating ring 31 drives the rotating rod 32 to move within the oil storage tank 1. The moving rotating rod 32 drives the stirring rod 321 to stir the sealing oil inside the oil storage tank 1. Simultaneously, during the rotation of the rotating ring 31, the first gear 322 meshes with the second gear ring 33, causing the first gear 322 to drive the rotating rod 32 to rotate. At this time, the rotating rod 32 drives the stirring rod 321 to rotate, causing the stirring rod 321 to stir the sealing oil inside the oil storage tank 1, further accelerating the heating effect of the sealing oil inside the oil storage tank 1, and rapidly melting the solidified sealing oil. At the same time, during the rotation of the stirring rod 321, its diamond-shaped side crushes the solidified sealing oil, breaking large pieces of sealing oil into smaller pieces, reducing the volume of the solidified sealing oil, and allowing heat to quickly melt the sealing oil, thereby further improving the efficiency of the heating wire 123 in heating and melting the sealing oil.

[0028] To inject the melted sealing oil into the equipment, an oil suction mechanism 2 is provided on the end cap 12. The oil suction mechanism 2 is used to suck out the sealing oil from the oil storage tank 1 and inject it into the equipment. The oil suction mechanism 2 includes an oil suction pipe 23 fixedly installed on the end cap 12. The oil suction pipe 23 is connected to the oil inlet pipe 121. An oil extraction cylinder 21 is fixedly installed at the end of the oil suction pipe 23 away from the end cap 12. The oil suction pipe 23 is connected to the oil extraction cylinder 21 through a first one-way valve. The first one-way valve delivers the sealing oil in the oil suction pipe 23 to the oil extraction cylinder 21. At the same time, a push rod 22 is slidably connected inside the oil extraction cylinder 21. One end of the push rod 22 extends to the outside of the oil extraction cylinder 21 and is fixedly installed with a push plate. A sealing plate is fixedly installed at the end of the push rod 22 inside the oil extraction cylinder 21. The sealing plate slides inside the oil extraction cylinder 21. The oil pump 21 is fixedly equipped with an oil injection pipe at the end away from the push rod 22. The oil injection pipe is connected to the oil pump 21 through a second one-way valve. The second one-way valve delivers the sealing oil in the oil pump 21 to the oil injection pipe. The operator pulls the push plate to move the push rod 22 to the outside of the oil pump 21. As the push rod 22 moves the sealing plate, the inside of the oil pump 21 gradually becomes a vacuum. Under the action of atmospheric pressure, the sealing oil inside the oil storage tank 1 enters the inside of the oil pump 21 along the oil inlet pipe 121, the oil suction pipe 23 and the first one-way valve. Then the operator connects the oil injection pipe to the equipment. The operator pushes the push plate to move the sealing plate through the push rod 22. The moving sealing plate squeezes the sealing oil to flow, so that the sealing oil is injected into the inside of the equipment through the second one-way valve and the oil injection pipe.

[0029] By agitating the solidified sealing oil and heating it simultaneously, during the process of the oil suction mechanism 2 drawing in the sealing oil, the unmelted sealing oil flows inside the oil inlet pipe 121. The heating wire 123 inside the oil inlet pipe 121 continuously heats and melts the sealing oil, thereby preventing the unmelted sealing oil from entering the oil suction mechanism 2 and causing blockage. This ensures the subsequent delivery of sealing oil and the normal operation of the oil injection mechanism.
