Description

Technical Field

[0001] This invention relates to the field of heat dissipation and waterproof cable technology, specifically to a testing device for heat dissipation and waterproof cables. Background Technology

[0002] The heat-dissipating and waterproof cable uses waterproof rubber for insulation; the cable filler also uses waterproof rubber; the cable sheath uses a waterproof rubber sheath and is suitable for water treatment equipment such as submersible pumps, coal mines, underwater operations, and underwater landscape lighting. This product uses high-density adhesive with waterproof functions, and due to the characteristics of the cable's own materials, it has good heat dissipation performance.

[0003] Cables often require testing before use. To ensure performance, heat-dissipating and waterproof cables have their internal conductors individually wrapped and then connected with insulation. Because the cables are coiled or bent during use, identifying damaged sections requires segment-by-segment testing. This necessitates selecting the required length of cable for testing, straightening it, and repeatedly cutting the outer layer with tools to expose the conductors before using a testing instrument. This process is cumbersome, time-consuming, and increases the workload of operators. Therefore, we propose a testing device for heat-dissipating and waterproof cables. Summary of the Invention

[0004] The purpose of this invention is to provide a testing device for heat-dissipating and waterproof cables to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a testing device for heat-dissipating and waterproof cables, comprising: a cable testing instrument body, a data connection line fixedly connected to the cable testing instrument body, two conductor clamps respectively provided at the two ends of the data connection line away from the cable testing instrument body, and a connecting shaft penetrating the conductor clamp on each conductor clamp; further comprising: an inlet assembly, the inlet assembly being connected to the outside of the cable testing instrument body, the inlet assembly being used to selectively straighten the cable, one end of the inlet assembly being connected to a guide member, and the guide member contacting the power part of the inlet assembly to guide the straightened cable; a first cable testing pretreatment assembly, the first cable testing pretreatment assembly being disposed on a single conductor clamp and connected to the conductor clamp via a connecting shaft; and a second cable testing pretreatment assembly, the second cable testing pretreatment assembly being disposed inside the first cable testing pretreatment assembly and contacting the conductor clamp.

Detailed Implementation

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1-11 This invention provides a technical solution: a testing device for heat-dissipating and waterproof cables, comprising: a cable testing instrument body 1, a data connection cable 101 fixedly connected to the cable testing instrument body 1, two conductor clamps 102 respectively provided at the two ends of the data connection cable 101 away from the cable testing instrument body 1, and a connecting shaft 10201 passing through the conductor clamp 102; further comprising: an inlet assembly 4, the inlet assembly 4 being connected to the outside of the cable testing instrument body 1, the inlet assembly 4 being used to selectively straighten the cable, one end of the inlet assembly 4 being connected to a guide 5, and the guide 5 being in contact with the power part of the inlet assembly 4 to guide the straightened cable; a first cable testing pretreatment assembly 2, the first cable testing pretreatment assembly 2 being disposed on the individual conductor clamp 102 and connected to the conductor clamp 102 via the connecting shaft 10201; and a second cable testing pretreatment assembly 3, the second cable testing pretreatment assembly 3 being disposed inside the first cable testing pretreatment assembly 2 and in contact with the conductor clamp 102.

[0030] When organizing cables, please refer to the attached diagram. Figure 1 , attached Figure 9-11 As shown, the inlet assembly 4 includes a mounting bracket 41 connected to the outside of the cable detector body 1. A rack segment 42 is provided on the outer side of the mounting bracket 41. One end of the mounting bracket 41 is connected to a limit ring 43, and the other end is connected to a guide member 5. A threaded rod 44 is connected inside the mounting bracket 41, and one end of the threaded rod 44 is connected to a drive motor 45. The drive motor 45 is connected to the outside of the mounting bracket 41. A movable bearing 46 is connected to the threaded rod 44, and a fixed frame 47 is connected to the outside of the movable bearing 46. A rotating shaft 48 is connected to the outside of the fixed frame 47, and a movable gear 49 that meshes with the rack segment 42 is connected to the rotating shaft 48. Cam blocks 481 are connected to both sides of 49, and cam blocks 481 are connected to rotating shaft 48. The cable enters from the limit ring 43. After the drive motor 45 is set, the threaded rod 44 starts to drive the movable bearing 46 to reciprocate and adjust. Because the threaded rod 44 is fixedly connected to the fixed frame 47, the fixed frame 47 moves and adjusts along the rack section 42. Because the rotating shaft 48 on the fixed frame 47 is connected to the movable gear 49, after the fixed frame 47 moves along the threaded rod 44, the movable gear 49 rotates with the rack section 42, so that the rotating shaft 48 drives the cam block 481 to straighten the cable, thus making it easier to straighten the cable.

[0031] After the cable is straightened, it needs to be guided to the detection position. The guide 5 includes an arc-shaped adjustment frame 51 connected to one end of the mounting bracket 41, and an adjustment shaft 52 is connected to the arc-shaped adjustment frame 51. A flywheel 53 is connected to the top of the adjustment shaft 52, and a semi-arc-shaped guide tube 54 is connected to the bottom of the adjustment shaft 52. One end of the threaded rod 44 is connected to a first bevel gear 55, and a second bevel gear 56 meshes with the outer side of the first bevel gear 55. A flywheel 53 is connected to the connecting rod 57 of the second bevel gear 56, and the flywheel 53 on the adjustment shaft 52 and the flywheel 53 on the connecting rod 57 are driven by a transmission belt 58. A bracket 59 is connected to the top of the connecting rod 57, and... The bracket 59 is connected to the mounting bracket 41. After the threaded rod 44 is driven to rotate, the first bevel gear 55, which is fixedly installed on the threaded rod 44, drives the second bevel gear 56 to start rotating. Because the second bevel gear 56 is rotatably installed on the bracket 59 through the connecting rod 57, and because the flywheel 53 on the connecting rod 57 and the flywheel 53 on the adjusting shaft 52 are driven by the transmission belt 58, the adjusting shaft 52 starts to rotate, which moves the cable entering the semi-arc guide pipe 54 along the pipe, so that the cable can be synchronously transmitted to the detection position after being straightened. The arc-shaped adjusting frame 51 in this solution is designed to facilitate the adjustment of the position of the semi-arc guide pipe 54.

[0032] Please see Figures 3-4The entire first cable inspection pretreatment assembly 2 is connected to the conductor clamp 102 via a connecting shaft 10201, so that the structure will not interfere with the normal use of the conductor clamp 102. This design can effectively improve the efficiency of the entire inspection device.

[0033] Please see Figures 5-8The first cable inspection pretreatment assembly 2 includes a loading seat 201 fixedly connected to the connecting shaft 10201 through the conductor clamp 102. An auxiliary block 20101 is fixedly installed on the top surface of the loading seat 201 near the conductor clamp 102. A positioning block 202 and a conical cutting block 203 are fixedly installed on the bottom surface of the loading seat 201 away from the auxiliary block 20101. A Y-shaped cylindrical groove 204 is opened inside the loading seat 201, and a cutting blade 205 is provided on the side wall of the inner cavity of the Y-shaped cylindrical groove 204. The second cable inspection pretreatment assembly 3 includes a first sliding block 301 movably connected to the auxiliary block 20101, a second sliding block 302 and a third sliding block 303 movably connected to the loading seat 201. The first sliding block 301 and the second sliding block 302 are connected to each other. All contact points are chamfered. The contact points between the second sliding block 302 and the third sliding block 303 are also chamfered. A limit block 304 is fixedly installed at the end of the third sliding block 303 that penetrates the loading seat 201. A limit spring 305 is fixedly installed on the side of the limit block 304 near the inner wall of the loading seat 201. The end of the limit spring 305 away from the limit block 304 is fixedly connected to the loading seat 201. Two auxiliary blocks 20101 are provided, symmetrically arranged on both sides of the conductor clamp 102. The limit block 304 is located directly below the conductor clamp 102. The cutting angle of the cutting blade 205 is n, and n satisfies 25°≤n≤45°. The hardness of both the conical cutting block 203 and the cutting blade 205 is HRC64. There are two positioning blocks 202. The number of tapered cutting blocks 203 is the same as the number of positioning blocks 202. The adjacent sides of the two positioning blocks 202 are arc-shaped. The user inserts the cable to be tested into the loading seat 201 through the opening below the Y-shaped cylindrical groove 204. The positioning blocks 202 at the bottom of the loading seat 201 can restrict the position of the cable. The tapered cutting blocks 203 can remove the outermost protective material of the cable by using their tapered shape and sharpness. The two conductors inside the cable and the conductor protective material are separated after being processed by the Y-shaped cylindrical groove 204 and the cutting blade 205. One conductor contacts the limiting block 304 through the Y-shaped cylindrical groove 204. At this time, the conductor clamp 102 is opened, the first sliding block 301 is squeezed, and the second sliding block... With the cooperation of 302 and the third sliding block 303, the positions of the two limiting blocks 304 move, restricting the position of the conductor inside. The protective material of the outer layer of the conductor is separated from the conductor under the cooperation of the two limiting blocks 304 until the conductor extends into the conductor clamp 102. At this time, the conductor clamp 102 can be released to hold it. The other conductor and its protective material extend out through another opening of the Y-shaped cylindrical groove 204 and come into contact with the air. Then, another conductor clamp 102 is used to hold the conductor. The cable tester body 1 can then be used to perform fault detection on the heat dissipation and waterproof cable. The conductor clamp 102 and its internal power device are existing structures. The conductor clamp 102 and the limiting spring 305 cooperate with each other to achieve the purpose of reusability of the whole device.
