Description

Technical Field

[0001] This utility model relates to the field of fiber optic temperature probe technology, and more specifically to a fiber optic temperature probe protection device. Background Technology

[0002] A fiber optic temperature probe is a sensor device that uses fiber optic technology to measure temperature. This probe achieves accurate temperature measurement by converting temperature changes into changes in optical signals. When an optical fiber is affected by temperature, its refractive index, length, or phase changes. These changes alter the propagation characteristics of the optical signal within the fiber, such as light intensity, frequency, or phase. By detecting these changes, the temperature of the environment in which the optical fiber is located can be calculated.

[0003] As shown in the prior art published in CN219121585U, although this prior art effectively protects the temperature probe and contacts by setting up protective components to avoid external damage and ensure that the entire probe device can safely and effectively transmit signals for a long time in the environment of normal operation of oil-immersed transformers, thus improving the service life of the fiber optic probe, when the protective components in this prior art are subjected to excessive impact and deform, the deformation of the protective components will directly squeeze the fiber optic temperature probe, thereby causing deformation and damage to the fiber optic temperature probe, which in turn affects the integrity of the fiber optic temperature probe. Utility Model Content

[0004] To overcome the aforementioned deficiencies of the prior art, this utility model provides a fiber optic temperature probe protection device. This device provides multiple layers of protection for the fiber optic temperature probe body through an outer ring, an inner ring supported by springs, and a support ring. This allows for multiple stress relief and buffering of impacts, preventing damage to the fiber optic temperature probe body from excessive impact. Furthermore, when the outer ring deforms due to impact, the multiple layers of protection from the inner ring and support ring prevent deformation and damage to the fiber optic temperature probe body, ensuring its integrity and solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fiber optic temperature probe protection device, including a protective component installed on the outside of the fiber optic temperature probe body for protection against impact damage;

[0006] The protective component includes two support rings, which are respectively fitted onto the top and bottom of the fiber optic temperature probe body. The support rings have an inner ring on the side away from the fiber optic temperature probe body, and two sets of pressure-relieving components are installed on the side of the inner rings close to the support rings.

[0007] Each pressure-relieving component includes multiple spaced springs, with the springs installed on the inner ring near the support ring, and the end of the spring away from the inner ring fixed to the support ring.

[0008] The inner ring is provided with an outer ring on the side away from the support ring.

[0009] In a preferred embodiment, the fiber optic temperature probe body includes a fiber optic body, a temperature probe, and a contact, wherein the contact is located on the front side of the temperature probe, and the temperature probe is located on the front side of the fiber optic body.

[0010] The optical fiber body, temperature probe, and contact are all located between the two support rings.

[0011] In a preferred embodiment, a heat-conducting shell is installed inside the front end of the outer ring, and the front end of the heat-conducting shell extends to the outside of the front end of the outer ring.

[0012] In a preferred embodiment, two sets of mounting components for assembly connection are provided between the two outer rings;

[0013] Each set of mounting components includes a mounting base and a connecting base. The connecting base is located on top of the mounting base, and the connecting base and the mounting base are respectively installed on the outer side of the two outer rings that are close to each other.

[0014] In a preferred embodiment, the top of the mounting base has multiple mounting holes that are evenly spaced apart, and the top of the connecting base has multiple connecting grooves that correspond vertically to the positions of the mounting holes.

[0015] In a preferred embodiment, a fastening bolt is provided inside the mounting hole, the bottom end of the fastening bolt passes through the mounting hole and extends into the connecting groove, and the outside of the fastening bolt is threadedly connected to the inner wall of the connecting groove.

[0016] In a preferred embodiment, a card plate is installed on the side of the inner ring near the outer ring, and a card slot is provided on the side of the outer ring corresponding to the card plate, with the end of the card plate away from the inner ring extending into the card slot.

[0017] The technical effects and advantages of this utility model are:

[0018] The fiber optic temperature probe body is protected by multiple layers of protection, including an outer ring, an inner ring supported by springs, and a support ring. This allows for multiple stress relief and buffering of impacts, preventing damage to the fiber optic temperature probe body from excessive impacts. Furthermore, if the outer ring deforms due to impact, the multiple layers of protection from the inner ring and support ring can prevent deformation and damage to the fiber optic temperature probe body, thus ensuring the integrity of the fiber optic temperature probe body.

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Refer to the instruction manual appendix Figure 1-5 This utility model provides a protective device for a fiber optic temperature probe, including a protective component installed on the outside of the fiber optic temperature probe body for protection against impact damage. The fiber optic temperature probe body includes a fiber optic body 5, a temperature probe 6, and a contact 7. The contact 7 is located on the front side of the temperature probe 6, and the temperature probe 6 is located on the front side of the fiber optic body 5. The fiber optic body 5, the temperature probe 6, and the contact 7 are all located between two support rings 1. The cooperation of the fiber optic body 5, the temperature probe 6, and the contact 7 facilitates temperature measurement by operators. Because a heat-conducting shell 8 is installed inside the front end of the outer ring 4, and the front end of the heat-conducting shell 8 extends to the outside of the front end of the outer ring 4, the heat-conducting shell 8 can conduct external temperature to the fiber optic temperature probe body, thereby reducing the contact between the fiber optic temperature probe body and the outside, thus improving the protective performance of this utility model for the fiber optic temperature probe body.

[0027] like Figure 1-4As shown, the protective component includes two support rings 1, which are respectively fitted onto the top and bottom of the fiber optic temperature probe body. An inner ring 2 is provided on the side of the support ring 1 away from the fiber optic temperature probe body. Two sets of pressure-relieving components are installed on the side of the inner ring 2 closest to the support ring 1. Each set of pressure-relieving components includes multiple spaced springs 3, which are installed on the side of the inner ring 2 closest to the support ring 1. The end of the spring 3 away from the inner ring 2 is fixed to the support ring 1. An outer ring 4 is provided on the side of the inner ring 2 away from the support ring 1.

[0028] The fiber optic temperature probe body is protected from all sides by two outer rings 4. When the outer ring 4 is damaged by impact, the inner ring 2, supported by multiple springs 3, provides secondary stress relief, and the support ring 1 further relieves the impact. This multiple stress relief and buffering can prevent excessive impact from damaging the fiber optic temperature probe body. Furthermore, when the outer ring 4 deforms due to impact, the inner ring 2 and support ring 1 provide multiple layers of protection to prevent deformation and damage to the fiber optic temperature probe body, thus ensuring the integrity of the fiber optic temperature probe body.

[0029] To facilitate the assembly of the two outer rings 4, such as Figure 1 and 2 As shown, two sets of mounting components for assembly and connection are provided between the two outer rings 4. Each set of mounting components includes a mounting base 9 and a connecting base 10. The connecting base 10 is located on the top of the mounting base 9, and the connecting base 10 and the mounting base 9 are respectively installed on the outer side of the two outer rings 4 that are close to each other. The top of the mounting base 9 has multiple mounting holes 11, which are evenly spaced apart. The top of the connecting base 10 has multiple connecting grooves 12, which correspond vertically to the positions of the mounting holes 11. The mounting holes 11 are provided with fastening bolts 13. The bottom end of the fastening bolts 13 passes through the mounting holes 11 and extends into the connecting grooves 12. The outside of the fastening bolts 13 is threaded to the inner wall of the connecting grooves 12. By the correspondence between the mounting holes 11 and the connecting grooves 12, the operator can operate the fastening bolts 13 into the mounting holes 11 and the connecting grooves 12, which facilitates the fixing of the mounting base 9 and the connecting base 10 together, thereby realizing the assembly and fixing of the two outer rings 4 and ensuring the connection stability of the two outer rings 4.

[0030] To ensure the installation stability of outer ring 4, such as Figure 3-5 As shown, a retaining plate 14 is installed on the side of the inner ring 2 near the outer ring 4, and a retaining groove 15 is opened on the side of the outer ring 4 corresponding to the retaining plate 14. The end of the retaining plate 14 away from the inner ring 2 extends into the groove 15. By engaging the retaining plate 14 with the groove 15, the retaining plate 14 can be limited and fixed to the outer ring 4 by the groove 15, thereby preventing the outer ring 4 from rotating and ensuring the connection stability between the outer ring 4 and the inner ring 2.

[0031] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
