Description

Technical Field

[0001] The utility model belongs to the field of petroleum detection, and particularly relates to a new type of inserting pin. Background Art

[0002] Fiber optic connectors are a high-end communication technology that inserts optical fibers into oil pipelines or storage tanks to monitor oil flow, temperature, pressure and other parameters in real time. They are commonly used in oil extraction, testing and management.

[0003] To address the problem of unstable signal transmission in fiber optic pin detection, the existing fiber optic pin has a fiber optic positioning capillary hole that runs through the pin. Corresponding to the capillary hole, a tapered entrance is opened on the end face of the positioning pin. The tapered tip transitions to the arc of the fiber optic positioning capillary hole. The optical fiber passes through the tapered hole into the capillary hole, and then glue is dispensed at the tapered entrance. The glue is sucked into the gap between the optical fiber and the capillary hole through the siphon effect of the capillary pin hole. The glue fixes the optical fiber and the fiber optic positioning capillary hole. Compared with traditional sensors, the improved fiber optic pin has higher sensitivity and accuracy, and can perform sensing work in harsh working environments.

[0004] However, during the oil exploration and production process, the friction between the exploration device and the soil and rocks causes the interior of the exploration device to be in a high temperature and high pressure state for a long time. The optical fiber pin is in a high temperature and high pressure state for a long time, causing the optical fiber positioning capillary hole to deform, thereby causing large deviations in the signal transmission and signal detection of the optical fiber pin. In severe cases, the optical fiber pin may be damaged and scrapped. During the oil exploration process, the exploration device needs to be stopped to protect the optical fiber pin inside the exploration device, resulting in low efficiency during the oil exploration process.

[0005] In summary, a new type of pin is urgently needed to solve the problem that the pin cannot withstand high temperatures in the existing oil exploration process. Utility Model Content

Furthermore, a heat dissipation layer is provided on the base 111 outside the ceramic insulation layer 113, effectively improving the heat dissipation performance of the ceramic insulation layer 113 and evenly distributing the temperature across the ceramic insulation layer 113, thereby avoiding the concentration of thermal stress and extending the service life of the material.

[0030] Specifically, in this embodiment, a new type of pin 100 includes a base 111. The base 111 is used to fix the optical fiber 110 and fix the optical fiber 110 to the connecting device.

The optical fiber 110 and the matrix 111 can be fixedly connected by extrusion or by embedding. Specifically, a conical shrinkage hole can be provided in the matrix 111, and the optical fiber 110 passes through the shrinkage hole and is embedded in the matrix 111.

[0033] Specifically, a ceramic insulation layer 113 is fixed on the side of the connecting end 120 and the fixed end 130 away from the base 111, wherein the ceramic insulation layer 113 is used to isolate heat and prevent external heat from being conducted into the pin through heat transfer. The ceramic insulation layer 113 and the base 111 of the connecting end 120 and the fixed end 130 are fixedly connected by inlaying, and can also be fixedly connected by pasting. The specific connection method includes but is not limited to the specific examples mentioned above. The thickness of the ceramic insulation layer 113 can be 0.5 mm, 1 mm, 0.3 mm, etc. The specific thickness can be selected according to actual insulation requirements.

[0034] In another embodiment, a heat dissipation layer is provided on the base 111 outside the ceramic thermal insulation layer 113. The heat dissipation layer is used to evenly distribute the heat of the connecting device along the heat dissipation device to avoid cracking of the ceramic thermal insulation layer 113 caused by heat concentration. The heat dissipation layer is embedded on the base 111, and one side of the heat dissipation layer is in contact with the ceramic thermal insulation layer 113. The thickness of the heat dissipation layer can be 0.3 mm, 0.5 mm or 1 mm. The specific thickness can be selected according to actual needs.

[0035] In another embodiment, a locking nut 112 is provided on the base 111, and the locking nut 112 is used to enable a wrench to drive the base 111 to rotate, thereby screwing the base 111 into the connecting device. The locking nut 112 and the base 111 can be manufactured using an integrated molding process, such as 3D printing, casting, etc. The locking nut 112 and the base 111 can also be manufactured separately and fixedly connected by welding, inlaying or other methods.

[0036] A fixing thread 121 is provided on the base 111 of the connecting end 120, and the fixing thread 121 is used to fix the base 111 to the fixing device. The length of the thread 121 can be 1 cm, 2 cm or 3 cm, and the specific length can be adjusted according to actual needs; a connecting positioning groove 131 is provided on the base 111 of the fixing end 130, and the connecting positioning groove 131 is used to engage with the connecting device. It should be explained that the connecting device is a connecting pipe, a detection rod or other device for connecting a pin. The connecting device is provided with a connecting snap ring corresponding to the connecting positioning groove 131, and the connecting snap ring is embedded in the connecting positioning groove 131, and then the fixing thread 121 is connected to the adjacent fixing device. By rotating the locking nut 112, the two adjacent connecting devices are fixedly connected through the pin, thereby realizing optical fiber 110 communication between adjacent devices.

[0037] Based on the above structure, when it is necessary to realize optical fiber 110 communication between two adjacent connecting devices, the optical fiber 110 is first passed through the connecting device, and then the connection positioning groove 131 of the pin fixing end 130 is embedded and connected with the connecting clamp of the connecting device on one side, and then the fixing thread 121 of the pin connecting end 120 is connected with the nut thread 121 of the connecting device, and the wrench is connected with the locking nut 112. The locking nut 112 is driven to rotate by the wrench to fix the pin and the connecting device close to the connecting end 120, thereby realizing the fixation of the adjacent fixing devices through the pin and realizing the communication connection of the optical fiber 110.

[0038] In this embodiment, ceramic insulation layers 113 are provided at both ends of the base 111, which can reduce heat transfer at the contact points with the pins, thereby achieving a heat insulation effect. At the same time, a heat dissipation layer is provided on the base 111 outside the ceramic insulation layer 113, which can effectively improve the heat dissipation performance of the ceramic insulation layer 113 and evenly distribute the temperature on the ceramic insulation layer 113, thereby avoiding the concentration of thermal stress and extending the service life of the material.

[0041] In this embodiment, a ceramic insulation layer 113 is fixed in the heat dissipation layer. Specifically, a ceramic insulation layer 113 is also fixed between the heat dissipation layer and the base 111.

The specific thickness can be selected according to actual needs.

[0046] Specifically, one end of the ceramic washer is squeezed against the locking nut 112, and the other end of the ceramic washer is squeezed against the nut. The nut is a standard nut, and the nut is fixed to the base 111 through a thread 121.

[0048] At the same time, by providing an insulating ceramic washer 114, the loosening of the thread 121 caused by thermal expansion can be reduced, ensuring that the nut can remain firmly connected under high temperature or frequent temperature changes, thereby improving the stability, safety and durability of the equipment, extending the service life of the equipment and reducing maintenance costs.

[0053] By providing a protective sleeve in the cavity, the optical fiber 110 is fixed in the protective sleeve by embedding, which can effectively protect the optical fiber 110 from the influence of the external environment and improve the service life of the optical fiber 110; during the transmission process, the optical fiber 110 may be damaged by external compression or temperature changes, and the protective sleeve can effectively fix and protect the optical fiber 110, reduce the influence of external factors on the transmission of the optical fiber 110, and ensure the stability and reliability of the transmission of the optical fiber 110.

[0056] In this embodiment, the protective sleeve is no shorter than the length of the substrate 111. After the optical fiber 110 is embedded in the protective sleeve, the protective sleeve is then embedded within the substrate 111. This design requirement effectively protects the substrate 111 and reduces accidental damage from the external environment or during operation. Furthermore, this design requirement helps improve the stability and reliability of the device, reducing the number of failures and repairs, and extending the device's service life.
