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.

[0017] This utility model provides the following technical solution: a DC power line swing test device, please refer to... Figures 1-4 The system includes an operating frame 1, with a guide groove 101 at the center of the upper surface of the operating frame 1. A power cord release roller 102 is installed on one side of the top of the operating frame 1, and a power cord take-up roller 103 is installed on the other side of the top of the operating frame 1. Side plates 2 are installed on both sides of the bottom of the operating frame 1. Left and right lead screws 201 are rotatably connected between the opposite sides of the two sets of side plates 2. A motor A202 is installed on the outer wall of one side of one set of side plates 2. The output end of the motor A202 is fixedly connected to one end of the left and right lead screws 201. The DC power cord is installed on the power cord release roller 102 in the form of a complete set of rollers. The DC power cord can be released by the power cord release roller 102 for subsequent swing test processing. At the same time, the other set of power cord take-up rollers 103 can take the DC power cord for take-up processing. The release and take-up of the entire set of DC power cord can be automatically released and taken up. Test components are installed on both sides of the upper part of the operating frame 1. The test components include a test frame 3. A slide 301 is installed at the bottom of the test frame 3. The outer wall of the slide 301 is slidably connected to the inside of the guide groove 101. A movable seat 302 is installed at the bottom of the slide 301. The inside of the movable seat 302 is threadedly connected to the outer wall of the left and right lead screws 201. A motor B303 is installed on the upper part of one side of the outer wall of the test frame 3. A turntable 304 is installed at the output end of the motor B303. A guide seat 305 is installed on one side of the end face of the turntable 304. A movable frame 306 is slidably connected to the outer wall of the guide seat 305. A screw 307 is provided on one side of the end face of the guide seat 305. A groove 308 is opened on the surface of the movable frame 306. The inside of the groove 308 is slidably connected to the outer wall of the screw 307. A knob 309 is threadedly connected to the outer wall of the screw 307. A collar 310 is installed on one side of the outer wall of the movable frame 306. The slide blocks 301 on the two sets of test frames 3 are slidably set in the guide grooves 101 on the operating frame 1, and the movable seats 302 on the slide blocks 301 are threadedly connected to the outer walls of the left and right lead screws 201. According to the left and right thread effect of the outer walls of the left and right lead screws 201, the motor A202 drives and controls the left and right lead screws 201 to rotate, so that the two sets of test frames 3 can move outward or inward synchronously. By slidably setting the movable frame 306 on the collar 310 to the outer wall of the guide seat 305 on the turntable 304, and the screw 307 on the guide seat 305 is in the slide groove 308 on the movable frame 306, during the DC power line swing test, the distance between the test frames 3 is adjusted by the motor A202 according to the swing test requirements. The size of the distance can realize the swing amplitude, and the length of the collar 310 can also realize the swing amplitude.

[0018] Working principle: When using this utility model, the DC power cable is installed on the power cable release roller 102 as a complete set of rollers. The power cable release roller 102 can release the DC power cable for subsequent swing testing. At the same time, another set of power cable take-up rollers 103 can take the DC power cable back up. The release and take-up are carried out automatically to release and take up the entire set of DC power cables. The slide blocks 301 on the two sets of test frames 3 are slidably set in the guide grooves 101 on the operation frame 1, and the movement of the slide blocks 301 is controlled. The seat 302 is threadedly connected to the outer wall of the left and right lead screws 201. Based on the left and right threaded appearance of the outer walls of the lead screws 201, the motor A202 drives and controls the rotation of the left and right lead screws 201, allowing the two sets of test frames 3 to move synchronously outwards or inwards. The movable frame 306 on the collar 310 is slidably mounted on the outer wall of the guide seat 305 on the turntable 304, with the screw 307 on the guide seat 305 positioned within the groove 308 on the movable frame 306. This allows for the DC power cord swing test. During the swing test, the spacing between the test frames 3 is adjusted by motor A202 according to the swing test requirements. The spacing determines the swing amplitude, and the length of the collars 310 also determines the swing amplitude. When the DC power cable is swing tested, one end of the DC power cable on the power cable release roller 102 is passed through two sets of collars 310 in sequence and wound onto the outer wall of the power cable take-up roller 103. During the test, the DC power cable needs to be kept in a slack state. Motor B303 drives the control turntable 304 to rotate half a circle and operate back and forth to achieve the swing test processing of the DC power cable. After the DC power cable is tested here, the power cable take-up roller 103 winds it up. At this time, the DC power cable moves to a new part, and the swing test can be performed again. During this process, no technical personnel are required to assist in the operation, reducing the workload and repetitive operations of the personnel involved. This effectively improves the testing efficiency and the use effect of the automatic swing test device for DC power cables.
