Abstract
Description
Technical Field
[0001] This utility model relates to the field of cable testing technology, and in particular to a testing device for the anti-interference capability of early warning cables. Background Technology
[0002] In modern industrial automation, smart grids, and communication transmission, early warning cables are increasingly widely used, and their performance directly affects the stability and reliability of system operation. With the increasingly complex electromagnetic environment, cables are highly susceptible to various types of electromagnetic interference, leading to signal transmission distortion, false alarms, and even system failure.
[0003] Existing testing equipment for the anti-interference capability of early warning cables is inconvenient to simulate complex scenarios such as multi-angle rotation and different stress states faced by cables in actual working conditions, resulting in significant deviations between test results and real-world conditions. Furthermore, it is not readily adaptable to the testing requirements of cables of different specifications. Therefore, it is necessary to develop a testing equipment for the anti-interference capability of early warning cables that can accurately simulate actual working conditions, is easy to operate, and has a wide range of applications, in order to ensure the normal operation of early warning cables in complex electromagnetic environments. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a testing device for the anti-interference capability of early warning cables.
[0005] This utility model is achieved by the following technical solution: a test device for the anti-interference capability of early warning cables, including a base, a test box fixedly connected to the top of the base, an inlet on the left and right sides of the test box, a rotating device on the top left side of the base, a sliding groove on the top right side of the base, and a moving device on the top right side of the base.
[0006] The rotating device includes a first fixed ring, with a bolt threaded inside the first fixed ring. A throttle handle is fixedly connected to the top of the bolt, and a fixed plate is rotatably connected to the bottom of the bolt. A first gear is fixedly connected to the left side of the surface of the first fixed ring, and a first motor is fixedly connected to the top of the base. A second gear is fixedly connected to the output end of the first motor.
[0007] Through the above technical solution, the first motor provides power for the rotation of the cable. By controlling the speed and direction of the first motor, the rotation speed and direction of the cable can be precisely controlled to meet the needs of different test conditions.
[0008] As a further improvement to the above solution, the first fixing ring is located on the left side of the detection box, and the right side of the first fixing ring is rotatably connected to the inside of the detection box.
[0009] As a further improvement to the above solution, the number of bolts is set to two, and the number of fixing plates corresponds to the number of bolts.
[0010] With the above technical solution, there are two fixing plates and two bolts, located inside the first fixing ring and the second fixing ring.
[0011] As a further improvement to the above solution, the fixing plate is located inside the first fixing ring, and the first gear meshes with the second gear.
[0012] Through the above technical solution, the fixing plate, under the action of the bolts, cooperates with the inner wall of the first fixing ring to firmly clamp the cable in the middle, ensuring the stability of the cable during rotation.
[0013] As a further improvement to the above solution, the moving device includes a second motor, the output end of which is fixedly connected to a lead screw, a moving plate is threadedly connected to the surface of the lead screw, a placement ring is fixedly connected to the top of the moving plate, and a second rotating ring is rotatably connected to the right side of the placement ring.
[0014] Through the above technical solution, the placement ring provides support for the other end of the cable and cooperates with the second rotating ring to enable the cable to remain stable during movement, while allowing the cable to rotate freely.
[0015] As a further improvement to the above solution, the second motor is located on the right side of the base, and the left side of the second motor is fixedly connected to the right side of the base.
[0016] As a further improvement to the above solution, the left and right sides of the lead screw are rotatably connected to the interior of the base, the lead screw is located inside the sliding groove, and the bottom surface of the moving plate is slidably connected to the inner wall of the sliding groove.
[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0018] This invention achieves omnidirectional cable rotation by setting a first fixed ring and a second fixed ring. A first motor drives the first fixed ring to rotate via gear transmission, and the second fixed ring rotates synchronously. At this time, various interference sources are applied inside the testing box. By monitoring the signal transmission stability of the cable under different rotation angles and tensions in real time, its anti-interference capability is comprehensively and accurately evaluated, ensuring that the test results truly reflect the cable's performance under complex operating conditions.
[0019] This invention utilizes a movable plate and a second motor to drive a lead screw, causing the movable plate, threaded onto the lead screw, to slide within a sliding groove. This, in turn, moves the placement ring and the second rotating ring, achieving precise adjustment of the cable tension. Different tensions affect the cable's internal structure and electromagnetic properties, allowing for testing of the cable's anti-interference performance under different stress states, thus more closely reflecting actual working conditions.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] Example:
[0029] Please combine Figure 1-5 This embodiment of an anti-interference capability testing device for early warning cables includes a base 1, a test box 2 fixedly connected to the top of the base 1, an inlet 3 on the left and right sides of the test box 2, a rotating device 4 on the top left side of the base 1, a sliding groove 5 on the top right side of the base 1, and a moving device 6 on the top right side of the base 1.
[0030] The rotating device 4 includes a first fixed ring 401, with a bolt 402 threaded inside the first fixed ring 401. A handle 403 is fixedly connected to the top of the bolt 402, and a fixing plate 404 is rotatably connected to the bottom of the bolt 402. A first gear 405 is fixedly connected to the left side of the surface of the first fixed ring 401, and a first motor 406 is fixedly connected to the top of the base 1. A second gear 407 is fixedly connected to the output end of the first motor 406. The cable is first passed through the first fixed ring 401, the inlets 3 on both sides of the detection box 2, the placement ring 604, and the second fixed ring 605 in sequence. The bolts 402 and the fixing plate 404 inside the first fixed ring 401 and the second fixed ring 605 are used to firmly clamp the two ends of the cable. The first motor 406 starts to operate, and the second gear 407 at its output end meshes with the first gear 405 on the outside of the first fixed ring 401, allowing the first fixed ring 401 to rotate flexibly on the right side of the detection box 2. At the same time, the second fixed ring 605 also rotates synchronously on the right side of the placement ring 604, realizing the omnidirectional rotation of the cable inside the detection box 2. During this process, various interference sources are applied to the test box 2. By monitoring the signal transmission stability of the cable under different rotation angles and tensions in real time, its anti-interference ability is comprehensively and accurately evaluated, ensuring that the test results truly reflect the performance of the cable under complex working conditions.
[0031] The first fixing ring 401 is located on the left side of the detection box 2, and the right side of the first fixing ring 401 is rotatably connected to the inside of the detection box 2.
[0032] There are two bolts 402, and the number of fixing plates 404 corresponds to the number of bolts 402.
[0033] The fixing plate 404 is located inside the first fixing ring 401, and the first gear 405 meshes with the second gear 407.
[0034] The moving device 6 includes a second motor 601, with a lead screw 602 fixedly connected to the output end of the second motor 601. A moving plate 603 is threadedly connected to the surface of the lead screw 602. A placement ring 604 is fixedly connected to the top of the moving plate 603. A second rotating ring 605 is rotatably connected to the right side of the placement ring 604. When the second motor 601 is started, it drives the lead screw 602 to rotate, causing the moving plate 603 to slide smoothly in the sliding groove 5, precisely adjusting the tension of the cable and simulating the stress state in actual use.
[0035] The second motor 601 is located on the right side of the base 1, and the left side of the second motor 601 is fixedly connected to the right side of the base 1.
[0036] The left and right sides of the lead screw 602 are rotatably connected to the inside of the base 1. The lead screw 602 is located inside the sliding groove 5, and the bottom surface of the moving plate 603 is slidably connected to the inner wall of the sliding groove 5.
[0037] The implementation principle of the anti-interference capability testing device for early warning cables in this embodiment is as follows: First, the cable is passed sequentially through the first fixing ring 401, the inlets 3 on both sides of the testing box 2, the placement ring 604, and the second fixing ring 605. The bolts 402 and fixing plates 404 inside the first fixing ring 401 and the second fixing ring 605 are used to firmly clamp both ends of the cable. Then, the second motor 601 is started, driving the lead screw 602 to rotate, causing the moving plate 603 to slide smoothly within the sliding groove 5, thereby moving the second fixing ring 605 and precisely adjusting the cable tension to simulate the stress state in actual use. During the testing phase, the first motor 406 starts operating, and its output second gear 407 meshes with the first gear 405 on the outside of the first fixing ring 401, allowing the first fixing ring 401 to rotate flexibly on the right side of the testing box 2. Simultaneously, the second fixing ring 605 also rotates synchronously on the right side of the placement ring 604, achieving omnidirectional rotation of the cable within the testing box 2. During this process, various interference sources are applied to the test box 2. By monitoring the signal transmission stability of the cable under different rotation angles and tensions in real time, its anti-interference ability is comprehensively and accurately evaluated, ensuring that the test results truly reflect the performance of the cable under complex working conditions.
[0038] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
