It can charge various models of electric vehicles by adjusting voltage and current. After the installation of the charging pile, various detection devices are needed to detect the electrical safety, charging performance, and damage of the charging cable of the charging pile to ensure the safety of using the charging pile.
[0003] Currently, when detecting the surface of the charging cable of the charging pile, an ultrasonic detector is usually used to detect the damage of the cable skin. During the use of the ultrasonic detector, the operating experience of the operator will greatly affect the detection result. When the operator moves the ultrasonic probe on the surface of the cable, since the contact surface between the cable and the probe is arc-shaped, if the probe is unstable or detaches from the cable during movement, the detection accuracy will be reduced, resulting in measurement errors.

[0023] The following will further describe the present application in detail with reference to the attached Figure 1 — Figure 5 to further illustrate the present application in detail,
[0024] The embodiments of the present application disclose a device for detecting new energy charging piles. Refer to Figure 1, a device for detecting new energy charging piles, including a detector body 1. The top of the detector body 1 is electrically connected to a probe 2. A connection component 3 is arranged on the right side of the top of the probe 2. The connection component 3 includes a pillar 31 slidably connected to the left side of the top of the probe 2. The bottom end of the pillar 31 is fixedly installed with an arc plate 32. A strap 33 is wound and connected to the bottom end of the arc plate 32. A limiting component 4 is arranged inside the connection component 3, and a coating component 5 is arranged on the right side of the connection component 3;
[0025] Refer to Figure 2 - Figure 4 , the limiting component 4 includes two threaded rods 41 threadedly connected to the front and rear sides of the top of the arc plate 32. The bottom of the threaded rod 41 is rotatably connected to a fitting plate 42. A rolling ball 43 is rotatably connected to the inside of the bottom of the fitting plate 42. The front and rear sides of the top of the fitting plate 42 are fixedly connected with telescopic connecting rods 44. The rolling balls 43 are equidistantly spaced inside the fitting plate 42. The rolling balls 43 roll on the surface of the cable, making it more convenient to push the probe 2. The end of the telescopic connecting rod 44 away from the fitting plate 42 is rotatably connected to the inner wall of the arc plate 32. The telescopic connecting rod 44 supports the fitting plate 42 to make it stable. The front and rear sides of the inside of the arc plate 32 are fixedly connected with reset springs 45. The end of the reset spring 45 away from the inner wall of the arc plate 32 is fixedly connected with a convex block 46. Inner grooves are opened on the front and rear sides of the inner wall of the arc plate 32. The reset spring 45 is fixedly installed inside the inner groove. The convex block 46 is adapted to be snap-fitted with the opening of the inner groove.
[0026] Refer to Figure 5 , the coating component 5 includes a connecting rod 51 fixedly installed at the right end of the arc plate 32. The right end of the connecting rod 51 is fixedly connected with a containing dish 52. The bottom end of the containing dish 52 is fixedly connected with a spray pipe 53. A sliding rod 54 is slidably connected to the right side inside the containing dish 52. The left end of the sliding rod 54 is fixedly connected with a buffer spring 55. The bottom of the sliding rod 54 is rotatably connected to a push rod 56. The bottom end of the push rod 56 is rotatably connected to a blocking block 57. The end of the buffer spring 55 away from the sliding rod 54 is fixedly installed on the inner wall of the containing dish 52. The blocking block 57 is slidably connected to the inside of the spray pipe 53 in an adapted manner. When the blocking block 57 disengages from the spray pipe 53, the coupling agent inside the containing dish 52 enters the inside of the spray pipe 53. The bottom of the right end of the containing dish 52 is fixedly connected with a telescopic rod 581. A pressure spring 582 is fixedly connected to the inside of the telescopic rod 581. The bottom end of the pressure spring 582 is rotatably connected to a roller 583. The front end of the roller 583 is rotatably connected to a push rod 584. The end of the sliding rod 54 away from the buffer spring 55 extends to the outside of the containing dish 52. The connection part of the push rod 584 and the roller 583 is located at a non-central position of the roller 583. The end of the push rod 584 away from the roller 583 and the bottom of the end of the sliding rod 54 outside the containing dish 52 are rotatably connected. When the roller 583 rotates, it will push the push rod 584 to swing.
[0027] Working principle: Before use, the operator opens the holding dish 52, then adds a coupling agent into the interior of the holding dish 52 and closes the holding dish 52;
[0028] After that, the operator loosens the strap 33, sleeved the arc-shaped plate 32 on the surface of the cable, then winds the strap 33 around the cable and connects it to the surface of the arc-shaped plate 32. Then, the bump 46 is loosened. At this time, the bump 46 separated from the arc-shaped plate 32 will move away from the arc-shaped plate 32 under the action of the resilience of the return spring 45. After that, the bump 46 will move and fit on the surface of the cable. At this time, the position of the arc-shaped plate 32 is preliminarily limited. Then, the operator rotates the threaded rod 41, and the threaded rod 41 will push the fitting plate 42 to move towards the surface of the cable until the ball 43 inside the fitting plate 42 fits on the epidermis of the cable. When the fitting plate 42 moves, it will drive the telescopic link 44 to extend and rotate. At this time, the fitting plate 42 always remains stable. Then, the operator can push the probe 2 towards the cable. At this time, the probe 2 slides relative to the support column 31 until the bottom of the probe 2 also fits on the surface of the cable; At this time, when the operator pushes the probe 2, the probe 2 will drive the arc-shaped plate 32 to move through the support column 31, and the arc-shaped plate 32 is always sleeved on the surface of the cable. And at this time, the ball 43 rolls on the surface of the cable to maintain the stability when the probe 2 moves.
[0029] During the movement of the arc-shaped plate 32, the roller 583 will stretch the telescopic rod 581 and move downward under the action of the elastic force of the pressure spring 582. At this time, the roller 583 will move downward and fit on the surface of the cable. At this time, during the process of pushing the probe 2 and the arc-shaped plate 32 to move, the roller 583 will roll on the surface of the cable. At this time, the roller 583 will push the second push rod 584 to swing. When the second push rod 584 swings upward, it will push the sliding rod 54 to move towards the interior of the holding dish 52. At this time, the sliding rod 54 compresses the buffer spring 55 and pushes the first push rod 56 to swing downward. At this time, the first push rod 56 pushes the plug 57 to move into the spray pipe 53. And then, when the roller 583 continues to rotate, it will cause the second push rod 584 to swing downward. At this time, the plug 57 is pulled upward by the first push rod 56 and separated from the spray pipe 53. At this time, the coupling agent inside the holding dish 52 will be discharged to the surface of the cable through the spray pipe 53. At this time, when the probe 2 continues to move, the coupling agent will be smeared at the contact position between the probe 2 and the cable, thereby making the detection accuracy of the probe 2 higher.
[0030] The above shows and describes the basic principle, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
