Description

Technical Field

[0001] The utility model relates to the technical field of optical cable census, in particular to an optical cable census device that can accurately identify. Background Technique

[0002] An optical cable is a communication cable assembly that uses optical fibers as the transmission medium and is made through a specific process. It mainly consists of optical fibers, a plastic protective sleeve, and a plastic outer skin. It does not contain metals such as gold, silver, copper, and aluminum inside, so it generally has no recycling value. The design of the optical cable aims to meet optical, mechanical, or environmental performance specifications. A certain number of optical fibers are arranged in a certain way to form a cable core, which is wrapped with a sheath, and some are also covered with an outer protective layer to achieve the transmission of optical signals. The basic structure of the optical cable includes parts such as a cable core, reinforcing steel wires, fillers, and a sheath. According to needs, it may also include components such as a waterproof layer, a buffer layer, and insulated metal wires. When constructing and maintaining an optical cable line, an optical cable census device is required. The optical cable census device uses advanced acoustic principles or the elastic effect of optical fibers to identify and analyze the vibration signals generated by tapping the optical cable, so as to achieve accurate census and positioning of the optical cable, improve the efficiency of optical cable line construction and maintenance, and effectively avoid damage to existing pipelines during construction.

[0003] A Chinese patent with the publication number of CN209783877U discloses an optical cable census device, which includes at least two optical cable census instruments. The optical cable census instrument includes an instrument main body and a vibration assembly. The vibration assembly includes a vibration rod for generating vibration, an electromagnet for controlling the vibration of the vibration rod, a return spring for resetting the vibration rod, an adjustment knob for adjusting the current input to the electromagnet, and a push button switch for controlling the power supply to the electromagnet. The adjustment knob and the push button switch are arranged on the instrument main body, the electromagnet and the return spring are arranged inside the instrument main body, and the vibration rod extends from inside the instrument main body to outside the instrument main body.

[0004] Although the above solution can use the vibration rod to replace manual tapping, when the optical cable census device performs simulated tapping, it needs to be close to and fit the optical cable. During the use of the hand-held optical cable census instrument, it is often inevitable for the operator's hand to shake. This kind of shake will directly affect the contact stability between the vibration rod and the optical cable. The hand shake will not only cause slight changes in the force and position of the vibration rod when tapping the optical cable, but also may make the tapping action unstable and discontinuous. This unstable tapping will introduce additional noise and interference signals, making it difficult for the optical cable census device to accurately capture and analyze the true vibration characteristics generated by the optical cable. Therefore, it does not meet the existing requirements. For this reason, we propose an optical cable census device that can accurately identify. Content of the Utility Model

[0005] The purpose of the present utility model is to provide an optical cable census device that can be accurately identified, so as to solve the problem that the shaking generated by hand-held operation during the use of the optical cable census device affects the use of the vibration rod, resulting in the difficulty of the optical cable census device to accurately capture and affecting the detection accuracy in the above-mentioned background technology.

[0006] To achieve the above purpose, the present utility model provides the following technical solution: an optical cable census device that can be accurately identified, including an optical cable census instrument, and a vibration part is arranged on the upper side of the rear end of the optical cable census instrument;

[0007] It further includes adjusting seats, which are arranged on both sides of the vibration part. Threaded rods are rotatably arranged inside the adjusting seats, and moving blocks are threadedly connected to the outer parts of the threaded rods. Guide grooves are respectively opened on the upper and lower sides inside the adjusting seats, and the guide grooves are slidably matched with the moving blocks. One end of each moving block extends to the outside of the adjusting seat;

[0008] It further includes a joint adjustment seat, which is opened on the upper end of the vibration part. One side inside each adjusting seat is rotatably provided with a first rotating rod, and one end of each first rotating rod extends into the inside of the joint adjustment seat and is rotatably matched with the joint adjustment seat. Second rotating rods are rotatably arranged on both sides inside the joint adjustment seat, and a third rotating rod is rotatably arranged at the middle position inside the joint adjustment seat. One end of the third rotating rod extends to the outside of the joint adjustment seat, and a knob is arranged at the end of the third rotating rod located outside the joint adjustment seat.

[0009] Preferably, first bevel gears are arranged on one end of the threaded rod and the outer wall of one end of the first rotating rod located inside the adjusting seat, and the first bevel gears are meshed with each other.

[0010] Preferably, second bevel gears are arranged on one end of the first rotating rod located inside the joint adjustment seat and one side of the outer wall of the second rotating rod, and the second bevel gears are meshed with each other.

[0011] Preferably, third bevel gears are arranged on one end of the second rotating rod and the outer wall of one end of the third rotating rod located inside the joint adjustment seat, and the third bevel gears are meshed with each other.

[0012] Preferably, bearings are arranged on the outer walls of the second rotating rods, the outer walls of the bearings are connected to the inner walls of the joint adjustment seats, and the inner walls of the bearings are connected to the outer walls of the second rotating rods.

[0013] Preferably, handrails are installed on the lower end and the lower sides of both sides of the optical cable census instrument.

[0014] Preferably, arc-shaped clamping blocks are arranged at one ends of the moving blocks located outside the adjusting seats.

[0015] Compared with the prior art, the beneficial effects of the present utility model are:

[0016] 1. The utility model is provided with adjusting seats on both sides of the vibration part. When the vibration part is in contact with the optical cable, by rotating the threaded rods on both sides, the threaded rods will drive the moving blocks to rotate synchronously. Under the limitation of the guiding grooves, the moving blocks can move linearly. The two moving blocks will drive the arc-shaped clamping blocks to move towards or away from each other. When the two arc-shaped clamping blocks move towards each other, the optical cable in the middle can be clamped and fixed. Therefore, when the operator's hand shakes, the vibration part will not be separated from the optical cable, ensuring the continuity of knocking and improving the detection accuracy.

[0017] 2. The utility model is provided with a joint adjustment seat at the upper end of the vibration part. When it is necessary to rotate the threaded rods on both sides, the operator only needs to rotate the knob on the joint adjustment seat. The knob will drive the third rotating rod to rotate. Under the meshing rotation of the third bevel gear, the second rotating rod can be rotated. The second rotating rod can drive the first rotating rod to rotate under the meshing transmission of the second bevel gear. And under the meshing transmission of the first bevel gear, the threaded rod can be rotated. Thus, by only rotating the knob, the synchronous rotation of the two threaded rods can be achieved. The operator does not need to perform multiple complex operations on the threaded rods on both sides, making the overall fixation more rapid and convenient and improving the operation efficiency.

[0018] 3. The utility model is provided with handrails at the lower end and on both sides of the optical cable census instrument. When the operator needs to operate with one hand to free the other hand for other tasks, the operator can choose to hold one of the handrails and keep the optical cable census instrument stable by adjusting the position and strength of the arm. And when more precise and stable control is required, the operator can hold the handrails on both sides with both hands and use the coordination of both hands to reduce the slight shaking of the hand, improving the detection accuracy.

Specific implementation manner

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Please refer to Figures 1-4 , the present invention provides a technical solution: an optical cable census device that can accurately identify, including an optical cable census instrument 1, and a vibration part 2 is arranged on the upper side of the rear end of the optical cable census instrument 1;

[0026] It further includes adjusting seats 3, which are arranged on both sides of the vibration part 2. Threaded rods 4 are rotatably arranged inside the adjusting seats 3. Moving blocks 5 are threadedly connected to the outside of the threaded rods 4. Guide grooves 6 are opened on the upper and lower sides inside the adjusting seats 3, and the guide grooves 6 are slidably matched with the moving blocks 5. One ends of the moving blocks 5 extend to the outside of the adjusting seats 3;

[0027] It further includes a joint adjustment seat 10, which is opened on the upper end of the vibration part 2. First rotating rods 8 are rotatably arranged on one side inside the adjusting seats 3. One ends of the first rotating rods 8 extend to the inside of the joint adjustment seat 10, and the first rotating rods 8 are rotatably matched with the joint adjustment seat 10. Second rotating rods 12 are rotatably arranged on both sides inside the joint adjustment seat 10. A third rotating rod 15 is rotatably arranged at the middle position inside the joint adjustment seat 10. One end of the third rotating rod 15 extends to the outside of the joint adjustment seat 10, and a knob 16 is arranged at the end of the third rotating rod 15 located outside the joint adjustment seat 10.

[0028] When in use, the vibration part 2 contacts the optical cable. The operator rotates the knob 16, and the power is transmitted to the second rotating rod 12 through the third rotating rod 15 and the third bevel gear 14, and the bearing 13 ensures stable rotation. Subsequently, the power is transmitted to the second bevel gear 11, the first rotating rod 8 and the first bevel gear 9, and finally the synchronous rotation of the two threaded rods 4 is realized. The rotation of the threaded rods 4 drives the moving blocks 5 to slide in the guide grooves 6, thereby pushing the arc-shaped clamping blocks 7 to move towards each other and clamp the optical cable. This design effectively prevents the vibration part from detaching from the optical cable due to hand tremors, ensures the continuity of knocking and the accuracy of detection. At the same time, the three-way handrail 17 provides multi-angle gripping options, enhancing the stability and convenience of operation.

[0029] Please refer to Figure 4 One end of the threaded rod 4 and the outer wall of one end of the first rotating rod 8 located inside the adjusting seat 3 are both provided with a first bevel gear 9, and the first bevel gears 9 are meshed with each other. The meshing connection of the first bevel gears 9 can ensure that the rotational power of the first rotating rod 8 is transmitted to the threaded rod 4 through the meshing action of the first bevel gears 9, realizing the synchronous rotation between the two, and further controlling the linear motion of the moving block 5, enhancing the transmission efficiency and stability of the system;

[0030] Please refer to Figure 4 One end of the first rotating rod 8 located inside the joint adjustment seat 10 and one side of the outer wall of the second rotating rod 12 are both provided with a second bevel gear 11, and the second bevel gears 11 are meshed with each other. Through the meshing of the second bevel gears 11, the power transmission between the first rotating rod 8 and the second rotating rod 12 is realized, making the entire transmission system more compact and efficient. At the same time, due to the transmission characteristics of the bevel gears, it can effectively bear larger axial forces and torques, improving the load-bearing capacity and stability of the system;

[0031] Please refer to Figure 4 One end of the second rotating rod 12 and the outer wall of one end of the third rotating rod 15 located inside the joint adjustment seat 10 are both provided with a third bevel gear 14, and the third bevel gears 14 are meshed with each other. The meshing connection between the third bevel gears 14 can convert the rotational action of the operator into the rotation of the second rotating rod 12, and further through the transmission of multiple-stage bevel gears, ensuring the continuity and stability of power transmission;

[0032] Please refer to Figure 4 Bearings 13 are provided on the outer walls of the second rotating rod 12, and the outer walls of the bearings 13 are connected to the inner walls of the joint adjustment seat 10, and the inner walls of the bearings 13 are connected to the outer walls of the second rotating rod 12. As a rotating support component, the bearings 13 can significantly reduce the friction and resistance during the rotation of the second rotating rod 12, improving the transmission efficiency. At the same time, the supporting role of the bearings can also ensure the stability and accuracy of the second rotating rod 12 during rotation, preventing deviation or shaking caused by vibration or external forces;

[0033] Please refer to Figure 1 、 Figure 2 and Figure 3 Handrails 17 are installed at the lower end and the lower sides of both sides of the optical cable census instrument 1. The handrails 17 provide holding points in multiple directions for the operator, enabling more flexible adjustment of the holding posture and force in a complex working environment, effectively avoiding equipment slipping or getting out of control caused by hand shaking or improper operation;

[0034] Please refer to Figure 1 and Figure 4, arc-shaped clamping blocks 7 are provided at one ends of the moving blocks 5 located outside the adjusting base 3. By contacting and clamping the optical cable with the arc-shaped clamping blocks 7, it can ensure that the vibrating part 2 always maintains stable contact with the optical cable during the knocking process, prevent detection errors caused by poor contact or detachment, and at the same time, the arc-shaped clamping blocks 7 are made of rubber material to avoid abrasion of the optical cable.

[0035] Working principle: When in use, the vibrating part 2 at the rear end of the optical cable census instrument 1 is brought into contact with the optical cable. Rotate the knob 16, and the knob 16 will drive the third rotating rod 15 to rotate. The third rotating rod 15 will drive one of the third bevel gears 14 to rotate. Under the meshing drive of the third bevel gear 14, the second rotating rod 12 can be rotated synchronously. The setting of the bearing 13 ensures the stability of the rotation of the second rotating rod 12. When the second rotating rod 12 rotates, it will drive one of the second bevel gears 11 to rotate. Under the meshing connection of the second bevel gear 11, the first rotating rod 8 can be rotated synchronously. The first rotating rod 8 can drive the threaded rod 4 to rotate synchronously through the meshing connection of the first bevel gear 9, thereby realizing the synchronous rotation of the two threaded rods 4. When the threaded rod 4 rotates, it will drive the moving block 5 to rotate synchronously. Since the moving block 5 is in sliding fit with the upper and lower guide grooves 6, the rotation of the moving block 5 will be axially limited. The rotation of the two moving blocks 5 will be converted into horizontal straight lines in opposite or opposite directions. When the two moving blocks 5 move towards each other, they will both drive the arc-shaped clamping blocks 7 to move synchronously. Thus, the two arc-shaped clamping blocks 7 moving towards each other will clamp and fix the optical cable in the middle, and further ensure the contact between the vibrating part 2 and the optical cable. When the operator's hand shakes, the vibrating part 2 will not be separated from the optical cable, ensuring the continuity of knocking, improving the detection accuracy. At the same time, by setting three handrails 17 in different directions to increase the holding points, it is convenient for the operator to better grasp the optical cable census instrument 1, providing the operator with multi-angle holding options, and effectively preventing the optical cable census instrument 1 from slipping due to improper operation.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
