Description

Technical Field

[0001] This utility model relates to the field of fiber optic temperature monitoring technology, specifically to a fiber optic through-connector. Background Technology

[0002] As a key component supporting the rotor system, the bearings of a hydro-generator typically operate in an environment submerged in lubricating oil. When the unit is running at high speed, the heat generated by friction between the bearings and the journals causes the temperature to rise. This temperature change directly affects the safe operation of the equipment, so continuous and real-time monitoring of the bearing temperature is essential.

[0003] In recent years, fiber optic temperature measurement technology has gradually become the preferred solution for bearing temperature monitoring due to its excellent anti-electromagnetic interference capability, compact size, and high stability. However, since the oil tank needs to be strictly sealed to avoid lubricating oil leakage, the optical fiber penetrating the oil tank wall must not only ensure smooth signal transmission but also have reliable sealing protection functions.

[0004] In addition, the connection between the internal optical fiber and the external transmission line lacks effective protection measures. During long-term operation, oil may seep into the connection, causing optical path loss and affecting the accuracy of temperature measurement. Utility Model Content

[0035] Example 1

[0036] A fiber optic through-connector. Figure 1 An exploded view of the overall structure of one embodiment of the present invention is shown; Figure 2 A cross-sectional view of the overall structure of one embodiment of the present invention is shown, as follows: Figure 1 and Figure 2 As shown, it includes: a converter plate body 1 and several connectors 2; the converter plate body 1 is the mounting carrier, providing mechanical support and fixing multiple connectors to ensure the stability of the optical fiber's penetration path inside and outside the bearing oil tank.

[0037] The adapter plate body 1 is provided with a plurality of first through holes 101. Each through hole 2 corresponds one-to-one with a first through hole 101, and each through hole 2 is independently installed in a through hole of the adapter plate body, forming a sealed through channel for a single optical fiber. The through holes 101 allow the two ends of the through hole 2 to be respectively positioned on both sides of the adapter plate body 1. In this embodiment, the first through holes 101 are a uniformly distributed array of through holes, and the diameter of the first through holes 101 matches the outer diameter of the through hole body 201. The through holes can be fixed by interference fit or threaded locking. The adapter plate body 101 can be fixed to the oil tank wall by flanges or bolts to ensure a flat sealing surface and prevent oil leakage. In this embodiment, an adapter flange 5 is included, with an adapter flange mounting hole 501 on the adapter flange 5. A reserved mounting hole 401 is provided on the bearing oil tank wall 4, and the adapter flange 5 is welded into the reserved mounting hole 401. The adapter plate body 1 and the adapter flange 5 are provided with bolt holes at corresponding positions for bolt connection and fixation. It also includes a number of mounting bolts 3. The adapter plate body 1 is provided with a number of second through holes 102. The adapter plate body 1 is connected to external objects through the second through holes 102 and the mounting bolts 3.

[0038] The connector 2 includes a connector body 201, a pair of connector joints 202, and an optical fiber ferrule 203. The pair of connector joints 202 are respectively disposed at both ends of the connector body 201, and are fixed to both ends of the connector body 201 via threads or snap-fit ​​connections. The connector ends can be configured with standard optical fiber interfaces (such as FC, SC, LC) to support quick insertion and removal. The middle portion of the optical fiber ferrule 203 is disposed within the connector body 201, and both ends of the optical fiber ferrule 203 are disposed within the connector joints 202. The middle portion of the optical fiber ferrule 203 is fixed within the connector body 201, and both ends extend into the connector joints 202 to interface with external optical fibers. The optical fiber ferrule 203 and the connector body 201 can be sealed with an adhesive such as epoxy resin. The contact surfaces between the two ends of the optical fiber ferrule 203 and the connectors are sealed using adhesive and elastic sealing rings (such as silicone) to prevent oil from penetrating along the optical fiber axis.

[0039] The optical fiber inside the bearing oil tank is connected to one end of the connector 202 and mated with the optical fiber ferrule 203. The optical signal passes through the optical fiber ferrule 203 through the adapter plate body 1 and reaches the outer connector 202. The optical fiber patch cord outside the oil tank is connected to the other connector 202 to complete the signal transmission. The assembly steps include: inserting the optical fiber ferrule 203 into the connector body 201, installing the connectors 202 at both ends and sealing them. Inserting the assembled connector 2 into the first through hole 101 of the adapter plate body 1 and fixing it by thread locking or crimping. The adapter plate body 1 is fixed to the reserved hole in the oil tank wall by flanges or bolts, and the overall sealing can be ensured by using sealing gaskets or rubber rings.

[0040] Furthermore, in this embodiment, the connector body 201 is axially provided with a through hole, and the connector joint 202 is provided with an optical fiber hole. The optical fiber hole is coaxially aligned with the through hole. The through hole includes a first diameter portion and a second diameter portion, the diameter of the first diameter portion being larger than the diameter of the second diameter portion. The two ends of the through hole are the first diameter portions. The axial through hole of the connector body 201 is divided into two cylindrical channels of different diameters. The first diameter portions are located at both ends of the through hole and are used to install the connector joint 202. A pair of connector joints 202 are respectively disposed at the first diameter portions at both ends of the through hole. The middle part of the optical fiber ferrule 203 is sealed in the second diameter portion of the through hole, and the two ends of the optical fiber ferrule 203 are sealed in the optical fiber hole. The second diameter portion is located in the middle of the through hole and is used to fix the middle section of the optical fiber ferrule 203. The diameter of the first diameter portion is slightly larger than the outer diameter of the connector joint 202, which facilitates the insertion and fixation of the connector. The aperture of the second diameter section matches the outer diameter of the fiber optic ferrule 203, ensuring the ferrule is centered and positioned without wobbling. The aperture of the second diameter section constrains the radial displacement of the fiber optic ferrule 203, preventing fiber alignment misalignment due to vibration or pressure fluctuations and ensuring the stability of optical signal transmission. The first diameter section provides installation space for the through-hole connector 202, reducing processing difficulty. The fiber optic hole and the through-hole are coaxially aligned, ensuring no optical path deflection at either end of the fiber optic ferrule 203. The diameter of the fiber optic hole is slightly larger than the outer diameter of the end of the fiber optic ferrule 203.

[0041] Furthermore, in this embodiment, the outer wall of the penetrator body 201 is provided with a first thread 2011, and the side wall of the first through hole 101 is provided with a second thread. The first thread 2011 and the second thread are compatible, and the penetrator body 201 is connected to the adapter plate body 1 through the first thread 2011 and the second thread. Furthermore, the portion of the outer wall of the penetrator body 201 with the first thread 2011 is designed as a slope, so that when the penetrator body 201 enters the first through hole 101, the penetrator body 201 and the first through hole 101 are sealed and locked. The slope is a gradually expanding slope, and the portion of the outer wall of the penetrator body 201 with the first thread 2011 gradually expands outward along the axial direction, forming a slope structure with a gradually increasing outer diameter. When the second thread on the side wall of the first through hole 101 of the adapter plate body 1 is screwed in, radial compression sealing is achieved through a conical surface fit.

[0042] Furthermore, in this embodiment, the penetrator connector 202 includes a fixing part 2021, and the penetrator connector 202 is connected to the penetrator body 201 through the fixing part 2021.

[0043] The fixing part 2021 includes a first outer diameter portion and a second outer diameter portion. The outer diameter of the first outer diameter portion is larger than the outer diameter of the second outer diameter portion, and the outer diameter of the second outer diameter portion is larger than the diameter of the first outer diameter portion. The outer diameter of the second outer diameter portion is adapted to the diameter of the first outer diameter portion. The second outer diameter portion is disposed within the through hole, and the first outer diameter portion is engaged with the outside of the through hole. The diameter is larger than the diameter of the first diameter portion of the through hole, forming an axial limiting flange to prevent the connector 202 from being over-inserted into the through-hole body 201.

[0044] Figure 3 This is a schematic diagram illustrating the use of one embodiment of the present invention, as shown below. Figure 3 As shown, the connector 202 includes a connector mating part 2022, which connects to an external fiber optic connector. The connector mating part 2022 includes a snap-fit ​​block 2024, which is disposed on the outer wall of the connector mating part 2022. The external fiber optic cable 6 is connected to the connector mating part 2022 through an external fiber optic connector 601.

[0045] The external fiber optic connector 601 is provided with a snap-fit ​​groove, and the connector mating part 2022 snaps into the external fiber optic connector through the snap-fit ​​block 2024 and the snap-fit ​​groove. The snap-fit ​​block can be trapezoidal or semi-circular protrusion, and the contour of the snap-fit ​​groove can be complementary to the shape of the snap-fit ​​block.

[0046] Furthermore, the outer wall of the penetrator body 201 is provided with an operating part 2012, which is used for gripping when installing the penetrator body 201. The outer wall of the operating part 2012 is provided with an anti-slip structure. The anti-slip structure can be an anti-slip pattern or anti-slip bumps.

[0047] This invention utilizes a connector with its two ends positioned on either side of the adapter plate body and fixed through a first through hole, directly enabling bidirectional transmission of optical fiber from inside to outside the bearing oil tank. This facilitates the fiber's passage through the bearing oil tank without affecting its sealing performance. The connector and through hole fit tightly together, enhancing resistance to vibration and pressure shocks.
