Description

Technical Field

[0001] This utility model relates to the field of optical fiber through-hole plate fixing technology, specifically a transformer optical fiber through-hole plate fixing device that is easy to maintain. Background Technology

[0002] Fiber optic temperature measurement systems are widely used in modern large oil-immersed transformers due to their advantages such as resistance to electromagnetic interference, high accuracy, and good reliability. The fiber optic through-hole is an important component of this system. It is installed on the transformer tank wall and serves as a transition and sealing interface for the temperature-measuring fiber optic cable to pass from the outside of the tank into the inside of the tank. Currently, traditional methods for fixing fiber optic cable trays in transformers typically involve manual support or the use of heavy cubic clamps. These methods have the following significant drawbacks: 1. Difficult to maintain: When it is necessary to maintain the through plate or its internal seals (such as O-rings), or to maintain the fiber optic splice or through connector, the overall circular design makes it unstable and requires manual support or the use of other tools to fix it, which is time-consuming and laborious. 2. Inconvenient debugging: Before installation, the angle of the through-hole tray needs to be adjusted to ensure smooth fiber optic cabling and avoid excessive bending. The rigid fixing method is extremely difficult to adjust, usually requiring repositioning of the hole or the addition of shims, which is inefficient. 3. High operational risk: Since the fiber optic cable pass-through components on the transformer fiber pass-through panel are very precise devices, any bumps or knocks will affect the temperature measurement signal and effect of the entire system. During maintenance, the lack of a stable fixing device increases the operation time and the safety risks to personnel and the pass-through panel. Therefore, there is an urgent need for a new fixing device to solve the above problems and enable rapid, simple and safe maintenance of the fiber optic cable tray.

[0003] The above content is only used to help understand the technical solution of the present invention and does not represent an admission that the above content is the closest prior art. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: An easy-to-maintain transformer fiber optic cable fixing device for supporting and fixing the cable body, comprising: The fixing assembly includes two sets of fixing bases placed in parallel to support the body of the through plate. One side of the fixing base is provided with a base support slope for supporting one end face of the through plate body, and a bayonet is provided at the lower part of the fixed base to limit the bottom of the through plate body. The support assembly includes a support rod disposed between the two sets of fixed bases for supporting and securing the fixed bases.

[0006] Furthermore, the fixing base is triangular in shape; The support rod has one set at the top and two sets at the bottom between the two sets of fixed bases, forming a triangular structure to improve the stability of the through plate body after it is fastened.

[0007] Furthermore, the lower end of the bayonet is set as an inclined surface, and the corresponding inclined surfaces in the two sets of fixed bases are arranged opposite each other to tighten and limit the through disc body.

[0008] Furthermore, threaded holes are provided at both ends of the support rod; The fixed base has fixing holes at both ends of the support rod. A screw is inserted into the fixing hole; One end of the screw is threaded into the fixing hole to fasten the support rod to the inside of the fastening base.

[0009] Furthermore, the fixed base has bearing holes inside and at both ends of the support rod, which are used to limit the position of the support rod with screws.

[0010] Compared with the prior art, the beneficial effects of this utility model are: This utility model places the through-plate body on the upper end of the fixed base, so that one end of the through-plate body rests against the inclined support surface of the base, and the bottom of the through-plate body is inserted into the slot.

[0013] 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.

[0014] Please see Figure 1-6 This utility model provides a technical solution: An easy-to-maintain transformer fiber optic cable fixing device for supporting and fixing the cable body 100, comprising: The fixing component 1 includes two sets of fixing bases 11 placed in parallel to support the through plate body 100. One side of the fixing base 11 is provided with a base support slope 15 for supporting one end face of the through plate body 100, and a bayonet 12 is provided at the lower part of the fixing base 11 to limit the bottom of the through plate body 100. The support assembly 2 includes a support rod 21 disposed between the two sets of fixed bases 11 for supporting and securing the fixed bases 11.

[0015] It should be noted that when fixing and supporting the circular through-plate body 100, the through-plate body 100 is placed on the upper end of the fixed base 11, so that one end face of the through-plate body 100 rests on the base support inclined surface 15, and the bottom of the through-plate body 100 is inserted into the slot 12. At this time, the through-plate body 100 is located between the two sets of fixed bases 11, completing the flexible fixing and support work of the through-plate body 100. There is no need to use hands or other tools to rigidly fix the through-plate body 100, which facilitates the maintenance of the through-plate body 100. When the angle of the through plate body 100 needs to be adjusted, since a flexible fixing method is adopted, the through plate body 100 only needs to be rotated and adjusted between the two sets of fixed bases 11. After the rotation adjustment, the through plate body 100 is still located between the two sets of fixed bases 11. Meanwhile, when maintaining the through plate body 100, the angle of the through plate body 100 can be switched directly between the two sets of fixed bases 11 by rotation, without having to pick up the through plate body 100, thus avoiding the through plate body 100 from being bumped and affecting the temperature measurement signal of the entire system.

[0016] Preferably, the base support slope 15 forms a 120° angle with the ground.

[0017] As an improvement, such as Figure 1-3 As shown, the fixed base 11 is triangular in shape; The support rod 21 has one set at the top and two sets at the bottom between the two sets of fixed bases 11, forming a triangular structure to improve the stability of the through plate body 100 after it is fastened.

[0018] Furthermore, such as Figure 4-5 As shown, the lower end of the bayonet 12 is set as an inclined surface 121, and the corresponding inclined surfaces 121 in the two sets of fixed bases 11 are arranged opposite to each other to tighten and limit the through plate body 100.

[0019] Furthermore, such as Figure 5-6 As shown, threaded holes 211 are provided at both ends of the support rod 21; The fixed base 11 has fixing holes 14 at both ends of the support rod 21. A screw 22 is inserted into the fixing hole 14; One end of the screw 22 is threaded into the fixing hole 14 to fasten the support rod 21 to the inside of the fastening base.

[0020] The fixed base 11 has bearing holes 13 inside and at both ends of the support rod 21, which are used to limit the support rod 21 with screws 22.

[0021] In the specific implementation of this utility model, such as Figure 1-3 , Figure 5-6 As shown, when assembling the two sets of fixed bases 11, the two ends of the three sets of support rods 21 are inserted into the corresponding bearing holes 13, and then the screws 22 are inserted into the fixing holes 14. The threaded section of the screws 22 is tightened into the threaded hole 211, thus completing the assembly of the two sets of fixed bases 11 and support rods 21. Then, the through plate body 100 is placed between the two sets of fixed bases 11, so that the rear end face of the through plate body 100 rests on the base support inclined surface 15, and the lower part of the through plate body 100 is located inside the bayonet 12 and is pressed and limited by the inclined surface 121. By setting the fixed bases 11 and the three sets of support rods 21 in a triangular structure, the stability of the through plate body 100 placed between the two sets of fixed bases 11 is improved. like Figure 2-5 As shown, this utility model places the through-plate body 100 at an angle between two sets of fixed bases 11, limits the bottom of the through-plate body 100 by the bayonet 12, and presses the through-plate body 100 against the inclined surface 121, so that the through-plate body 100 is in a central state between the fixed bases 11, thereby achieving flexible fixation of the through-plate body 100. When it is necessary to adjust the angle of the through-plate body 100, it is only necessary to rotate the through-plate body 100 between the two sets of fixed bases 11 for adjustment, which is convenient for debugging. Furthermore, since the present invention uses a flexible fixing method for the through plate body 100, the through plate body 100 can be quickly installed or removed from the fixing device when it is being repaired, making maintenance convenient. like Figure 1-2 As shown, when multiple parts of the through plate body 100 need to be inspected, each part of the through plate body 100 can be inspected simply by rotating and adjusting the through plate body 100 between the two sets of fixed bases 11. There is no need to pick up the through plate body 100 for inspection, which greatly reduces the risk of bumps and knocks during the handling of the through plate body 100.
