[0002] Cables are a very important type of electrical material. As the degree of cableization in urban power grids continues to increase, the requirements for the reliability of cable power supply are also constantly increasing. Accurately grasping the internal condition of cables and formulating corresponding maintenance strategies can effectively prevent cable joint accidents. Therefore, cable joints must be inspected.

[0003] In the prior art, for example, Chinese patent CN216350373U discloses a quality inspection device for cable joints, including a housing, a machine vision acquisition mechanism for acquiring images of the cable joints, and an angle adjustment mechanism for driving the machine vision acquisition mechanism to rotate. Both the machine vision acquisition mechanism and the angle adjustment mechanism are disposed inside the housing. The machine vision acquisition mechanism is provided with a receiving cavity for placing the cable joint, and the receiving cavity is provided with at least one acquisition module for acquiring images of the cable joints. The angle adjustment mechanism is connected to the machine vision acquisition mechanism to drive the machine vision acquisition mechanism to rotate, thereby driving the acquisition module to rotate and acquire images of the cable joints from various angles. This inspection device can effectively inspect the quality of cable joints, thereby effectively reducing safety hazards caused by manufacturing quality problems of cable joints.

[0004] However, the aforementioned testing device is closed at one end and open at the other. The cable end connector is inserted into the receiving cavity from the opening for testing. That is, the aforementioned testing device can only detect the cable end connector and cannot detect the cable intermediate connector. Utility Model Content

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. This utility model provides a device for detecting the quality of electrical materials. In the initial position, the notch on the gear and the notch on the circular bracket are connected. The cable enters the detection area through the notch. The sliding rack drives the gear to rotate, which in turn drives the support rod to rotate, which in turn drives the camera to rotate around the axis of the circular bracket. The rotation of 180° allows the two cameras to capture images of the cable surface and detect the appearance quality of the cable joint. At this time, the notch on the gear and the notch on the circular bracket are set opposite each other. After the detection is completed, the rack slides in the opposite direction, driving the gear to rotate in the opposite direction until the notch on the gear and the notch on the circular bracket are connected. The cable is then removed, completing the quality detection of the cable joint. That is, this device can simply and quickly detect the quality of cable joints.

[0017] 2. In this utility model, the spring force of the compression spring makes the slider position away from the base. At this time, the gear notch and the ring bracket notch are connected, which facilitates the cable to enter the detection area. During the detection process, the slider is pushed to drive the rack towards the base, so that the gear drives the camera to rotate and collect the image of the cable surface. After rotating 180° to complete the acquisition, the slider is released, and the restoring force of the compression spring pushes the slider to move in the opposite direction to realize the reset of the slider. The operation is simple and improves the detection efficiency of cable intermediate joints. Attached Figure Description

[0023] The technical solution of this utility model will be further described in detail below with reference to specific embodiments. Parts not described or disclosed in detail in the following embodiments of this utility model should be understood as prior art known or should be known by those skilled in the art, such as how the driven gear 2 is rotated and installed on the ring bracket 1.

[0024] Example

[0025] A device for detecting the quality of electrical materials includes a base 4, which is a rectangular plate structure. Two coaxial circular support brackets 1 are fixedly mounted on the base 4, with their axes parallel to the base 4. The circular support brackets 1 are parallel to the base 4 via connecting rods. The connecting rods can be circular or square; in this embodiment, the connecting rods are circular, and their diameter is less than or equal to the width of the circular support brackets 1. The connecting rods are perpendicular to the base 4, and one end of the connecting rod is fixedly connected to the base 4 by welding or bolting. The other end of the connecting rod is fixedly connected to the outer wall of the circular support brackets 1 by welding.

[0026] A detection area 102 is formed between two annular supports 1. One of the annular supports 1 is coaxially rotatably equipped with a driven gear 2 located within the detection area 102. Figure 3 and Figure 4 As shown, the driven gear 2 is mounted on the left annular bracket 1, and is located on the right side of the annular bracket 1, i.e., the driven gear 2 is located within the detection area 102. The driven gear 2 has a through hole at its center, the diameter of which is greater than or equal to the inner diameter of the annular bracket 1. Both the driven gear 2 and the two annular brackets 1 have notches for the cable to enter the detection area 102. For ease of description, in this embodiment, the notch on the annular bracket 1 is referred to as the first notch 103, and the notch on the driven gear 2 is referred to as the second notch 202. Figure 1 As shown, the opening of the first notch 103 faces away from the base 4, and the first notch 103 is connected to the inner cavity of the annular bracket 1; the width of the second notch 202 is equal to the width of the first notch 103, and the second notch 202 is connected to the through hole at the center of the driven gear 2. When the first notch 103 and the second notch 202 are connected, the cable passes through the first notch 103 and the second notch 202, and finally rests on the inner wall of the two annular brackets 1, with the intermediate joint located in the detection area 102.

[0027] Two support rods 201, symmetrically distributed along their axis, are fixedly mounted on the end face of the driven gear 2. The support rods 201 are circular rod-shaped structures, such as... Figure 4 As shown, the support rod 201 is perpendicular to the end face of the driven gear 2. The support rod 201 is connected to the driven gear 2 in such a way that the end face of the driven gear 2 has a mounting hole, and the support rod 201 is interference-fitted with the mounting hole. The support rod 201 extends along a direction parallel to the axis of the driven gear 2 and passes through the detection area 102, that is, the support rod 201 extends toward the right annular bracket 1. It should be noted that in this embodiment, the right end of the support rod 201 does not contact the annular bracket 1, that is, there is a gap between the right end face of the support rod 201 and the left end face of the annular bracket 1.

[0028] Each support rod 201 is equipped with a camera 5, and each support rod 201 is equipped with two light sources 6 located on both sides of the camera 5, so that the image captured by the camera 5 is clearer.

[0029] A rack 3, which is slidably connected to the driven gear 2, is mounted on the base 4. The transmission connection between the rack 3 and the driven gear 2 is as follows: a transmission gear 101 is rotatably mounted on the annular support 1, and both the rack 3 and the driven gear 2 mesh with the transmission gear 101. Specifically, as shown... Figure 1 As shown, the transmission gear 101 is located to the lower right of the driven gear 2; the transmission gear 101 is connected to the annular bracket 1 by a mounting shaft fixedly connected to the annular bracket 1, the axis of the mounting shaft being parallel to the axis of the annular bracket 1, and the transmission gear 101 and the mounting shaft being coaxially rotatably connected. The rack 3 is located below the transmission gear 101 and meshes with it, specifically as follows... Figure 1 As shown, the base 4 has a groove extending perpendicular to the axis of the driven gear 2. A slider 401, located within and sliding along the groove, is fixedly connected to the rack 3. The slider 401 is located below the rack 3, and the two are connected by bolts. The slider 401 has a guide hole 402, the axis of which is parallel to the sliding direction of the slider 401. A guide rod 403, fixedly connected to the base 4 and capable of extending into the guide hole 402, is provided in the groove. The axis of the guide rod 403 coincides with the axis of the guide hole 402. In this embodiment, the guide hole 402 is a blind hole, and a compression spring 404 is provided at the bottom of the guide hole 402. One end of the compression spring 404 is fixedly connected to the end of the guide rod 403 that extends into the guide hole 402, and the other end of the compression spring 404 is fixedly connected to the bottom wall of the guide hole 402.

[0030] The initial state of the device is as follows Figure 1 As shown, under the action of the compression spring 404, part of the slider 401 is located outside the groove. At this time, the first notch 103 and the second notch 202 are connected. The two cameras 5 are located at the same horizontal position and are symmetrically arranged along the axis of the driven gear 2. The cable passes through the first notch 103 and the second notch 202 at the same time and rests on the inner wall of the two annular brackets 1, so that the intermediate connector is located in the detection area 102. Pushing the slider 401 causes the rack 3 to move to the left, causing the transmission gear 101 to rotate clockwise, and then causing the driven gear 2 to rotate counterclockwise until the slider 401 abuts against the bottom of the groove. Figure 2As shown, at this time, the driven gear 2 rotates 180°, that is, the camera 5 initially located on the left side of the driven gear 2 axis has rotated to the right side of the driven gear 2 axis, and the camera 5 initially located on the right side of the driven gear 2 has rotated to the left side of the driven gear 2 axis. That is, the camera 5 initially located on the left side of the driven gear 2 captures the image of the lower surface of the cable, and the camera 5 initially located on the right side of the driven gear 2 captures the image of the upper surface of the cable. Both cameras 5 capture the image of the entire surface of the cable, and the compression spring 404 is in a compressed state. After the acquisition is completed, the slider 401 is released. Under the action of the restoring force of the compression spring 404, the slider 401 slides in the opposite direction, driving the transmission gear 101 to rotate counterclockwise, and then driving the driven gear 2 to rotate clockwise, until the gear returns to its original position. At this time, the first notch 103 and the second notch 202 are connected, the cable is taken out, and the detection of the intermediate joint is completed.

[0031] A limiting block extending away from the guide rod 403 is provided on the outer wall of the end of the guide rod 403 that extends into the guide hole 402. The limiting block has a ring structure, and its inner diameter is equal to the diameter of the guide rod 403. A limiting ring extending towards the center is fixedly provided on the inner wall of the guide hole 402. The limiting ring is located at the opening of the guide hole 402, and its inner diameter is smaller than the outer diameter of the limiting block. The outer diameter of the limiting ring is equal to the diameter of the guide hole 402. The limiting block and the limiting ring cooperate to limit the extreme displacement of the slider 401, prevent the driven gear 2 from rotating too far in the opposite direction, and ensure that the driven gear 2 returns to its original position.
