[0022] The terms used in the present invention are those commonly used in the art in view of the functions of the present invention, but these terms may vary according to the intentions of those skilled in the art, precedents, or new technologies in the art. In addition, specific terms may be selected by the applicant, and in such cases, their detailed meanings will be described in the detailed description of the present invention. Therefore, the terms used in the specification should not be understood as simple names, but rather as the meanings of the terms and the overall description of the present invention.

[0023] Reference Figure 1 and Figure 2 This embodiment provides a quickly pluggable sealing oil signal tube insulation device, including a load-bearing part 1, on the outer side of which a connecting part 2 is sleeved; the interior of the connecting part 2 is arranged on the movable part 3, and both ends of the movable part 3 pass through the connecting part 2; the outer wall of the connecting part 2 is sleeved with a locking part 4; when the locking part 4 and the movable part 3 are sleeved, the movable part 3 cannot move, and at this time the movable part 3 and the load-bearing part 1 are in a plug-in state, and the connecting part 2 is fixed.

[0024] Among them, the bearing part 1 is the end of the signal tube body 11, which is used to fix and install the connecting part 2. The main body of the moving part 3 is a moving rod, which runs through the entire connecting part 2. When the moving rod moves inward, it will be plugged into the end of the internal signal tube body 11, thereby completing the locking of the connecting part 2.

[0025] Preferably, the locking portion 4 is annular and is sleeved on the outer wall of the connecting portion 2. It can slide up and down on the outside. After sliding and sleeved with the moving portion 3, the locking portion 4 will squeeze the outside of the moving portion 3, thereby causing the moving portion 3 to move inward, thereby completing the sleeved connection with the bearing portion 1.

[0026] In summary: during installation, the locking part 4 is moved so that the locking part 4 moves and engages with the moving part 3, and then the moving part 3 is squeezed by the locking part 4, and moves internally and engages with the load-bearing part 1, completing the locking of the connecting part 2 and the installation. During disassembly, the locking part 4 is controlled to move so that the locking part 4 and the moving part 3 are separated. At this time, the external pressure of the moving part 3 disappears, the moving part 3 and the load-bearing part 1 are separated, and the connecting part 2 can be quickly disassembled.

[0027] Reference Figure 2 As an optional embodiment, a quickly pluggable sealing oil signal pipe insulation device is provided, including a locking portion 4 having an end near the moving portion 3 and a guiding inclined surface 41.

[0028] The guide inclined surface 41 is provided to facilitate the movement of the movable part 3 inward when the locking part 4 and the movable part 3 are connected, thereby squeezing the movable part 3 .

[0029] Preferably, when the locking portion 4 is controlled to move and contacts the moving portion 3 inside the connecting portion 2 , the guiding inclined surface 41 will squeeze the moving portion 3 , causing the moving portion 3 to move inward and be engaged with the bearing portion 1 .

[0030] Furthermore, a locking spring 42 is provided at the other end of the locking portion 4 .

[0031] The locking spring 42 is configured to push the locking portion 4 to move toward the moving portion 3 , so that the locking portion 4 is sleeved on the outside of the moving portion 3 , thereby completing the locking of the connecting portion 2 .

[0032] Furthermore, a groove 21 is formed on the outer wall of the connecting portion 2 , and the locking portion 4 and the locking spring 42 are disposed inside the groove 21 .

[0033] Preferably, the groove 21 is provided to fix the movement of the locking spring 42 so that the locking portion 4 can only move up and down within a certain range, thereby completing the connection and separation of the locking portion 4 and the moving portion 3.

[0034] Furthermore, the connecting portion 2 is sleeved on the end of the supporting portion 1 .

[0035] The connecting portion 2 is provided at one end of the carrying portion 1 , making disassembly more convenient and quick.

[0036] In summary: during disassembly, first control the locking part 4 to move in the direction of the locking spring 42, so that the locking spring 42 is in a compressed state, the locking part 4 and the movable part 3 are separated, and the external pressure of the movable part 3 disappears. At this time, the movable part 3 is controlled to move outward and separate from the load-bearing part 1 to complete the disassembly of the connecting part 2; during installation, squeeze the locking part 4 to separate the movable part 3, and then put the connecting part 2 on the outer side of the end of the load-bearing part 1, and then release the locking part 4, so that the locking spring 42 pushes the locking part 4 to move in the direction of the movable part 3, so that the locking part 4 squeezes the movable part 3, and the inner side of the movable part 3 will be disassembled from the load-bearing part 1, thereby completing the rapid fixation of the connecting part 2.

[0037] Reference Figure 1 and Figure 2 As an optional embodiment, a quickly pluggable sealed oil signal tube insulation device is provided, including a bearing portion 1 including a signal tube body 11, and an oil pipe 12 arranged inside the signal tube body 11.

[0038] Among them, the signal tube body 11 is responsible for transmitting the pressure signal of the sealing oil, which is used to monitor and adjust the sealing oil system in real time, ensure the lubrication and cooling of the mechanical seal, prevent medium leakage, protect the sensor from corrosion and pollution, and provide safety warnings under abnormal conditions to ensure the safety and efficient operation of the equipment; the oil pipe 12 plays the role of transporting lubricating oil, hydraulic oil or other oils in mechanical equipment and systems, ensuring that all moving parts are fully lubricated and cooled, transmitting power, controlling movement, reducing wear, extending equipment life, and maintaining system pressure stability to ensure efficient and safe operation of mechanical equipment.

[0039] Furthermore, detection points 121 are provided at both the upper and lower ends of the oil pipe 12 .

[0040] The detection points 121 at the upper and lower ends of the oil pipe 12 are used to detect whether the sealing and insulation of the equipment are complete, so as to prevent damage to the equipment due to poor insulation.

[0041] Furthermore, a connecting disk 31 is provided on the outer side of the moving portion 3 , and an unlocking spring 32 is fixedly connected to the outer wall of the connecting disk 31 .

[0042] Among them, the connection plate 31 is used to connect the unlocking spring 32 and the moving part 3, so that when the moving part 3 is separated from the locking part 4, it pushes the moving part 3 to move outward and separate from the inner bearing part 1, thereby completing the unlocking of the connecting part 2.

[0043] Preferably, after the locking part 4 and the movable part 3 are separated, the unlocking spring 32 will push the movable disk to move outward, thereby controlling the movable part 3 to move outward and separate from the bearing part 1, so that the locking of the connecting part 2 is cancelled. At this time, it is only necessary to push the connecting part 2 to disassemble the connecting part 2, thereby achieving the effect of quick disassembly.

[0044] Furthermore, a sealing portion 5 is provided between the bearing portion 1 and the connecting portion 2 , including a sealing ring 51 provided on the connecting portion 2 and a sealing gasket 52 provided on the bearing portion 1 .

[0045] Among them, the sealing ring 51 is used to isolate the load-bearing part 1 and the connecting part 2 to achieve the insulation effect, and the sealing gasket 52 is used to seal the interface between the load-bearing part 1 and the connecting part 2 to prevent the insulation effect from disappearing due to oil leakage.

[0046] Furthermore, at least two bosses 511 are provided at the end of the sealing ring 51 , and one of the bosses 511 is provided inside the connecting portion 2 .

[0047] Among them, the boss 511 is set at the upper part of the position prone to breakage, and at least two bosses 511 are designed. First, it is used to fix the position of the insulation structure and the connecting part 2 to prevent the sealing ring 51 from being skewed during installation, thereby solving the problem of poor insulation stability of the generator sealing oil signal tube. At the same time, the original polyethylene material is replaced with epoxy resin material, and the softness of the epoxy resin material itself is used to solve its low strength and easy breakage problems.

[0048] In summary: the present invention replaces the original polyethylene material with epoxy resin material, thereby solving the problems of low strength and easy breakage; when disassembling, the movable part 3 and the bearing part 1 are separated by squeezing the locking part 4, so that the connecting part 2 can be quickly disassembled and the sealing ring 51 can be replaced, thereby achieving the effect of quick disassembly.

[0049] Finally, it should be pointed out that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways without departing from the scope of the present invention.
