Description

Technical Field

[0001] The present invention relates to the technical field of DC charging pile detection, and in particular to a portable DC charging pile detection device. Background Art

[0002] Charging piles are devices that recharge electric vehicles, similar in function to gas pumps at gas stations. They can be fixed to the ground or wall and installed in public buildings (such as public buildings, shopping malls, and public parking lots), residential parking lots, or charging stations. They can charge various models of electric vehicles at different voltage levels. To ensure that the quality and performance of charging piles meet standards, they require regular inspection.

[0003] In the prior art, when operation and maintenance personnel use portable detection devices to diagnose faulty charging piles, the detection devices directly display whether the charging pile is abnormal and upload the detection results to the intelligent power distribution system, triggering an operation and maintenance work order or updating the health status of the pile. During the charging pile detection process, the charging gun in the charging pile needs to be inserted into the interface module in the DC charging pile detection device, and then the detection device is used for detection. However, in actual use, some charging guns may be slightly deformed at the muzzle due to collisions with other objects due to long-term use. This results in the charging gun and the interface module not being completely aligned, making it more laborious to insert the charging gun into the interface module. Moreover, when pulling out the charging gun, the entire detection device may be moved, making it even more laborious to detect multiple charging piles. Summary of the Invention

[0039] The second fixing mechanism includes a push plate 37 and a moving block 38. The push plate 37 cooperates with the raised block 33. The push plate 37 is slidably fitted inside the inner cylinder 34. Both ends of the moving block 38 are slidably sleeved with guide rods 39.

A spring 42 is fixedly installed between the bottom of the fixed block 41 and the inner wall of the moving block 38.

[0040] Working principle: When in use, the two fixing rods 1 7 and the two fixing rods 2 8 are fixedly installed on the top of the detection box 1, and two operating mechanisms are used respectively to make the two fixing mechanisms 1 and the two fixing mechanisms 2 move accordingly. The movement process of one operating mechanism and the corresponding fixing mechanism 1 and fixing mechanism 2 is as follows: Turn the adjusting rod 23, the adjusting rod 23 descends along the fixing rod 1 7, the lifting plate 24 slides downward along the two guide rods 1 25, and drives the transmission rod 30 to slide inside the transmission groove 29, the transmission rod 30 acts on the moving block 1 26, and the moving block 1 26 is forced to drive the fixed block 1 27 to slide outward, and the T-shaped slider 2 32 at the bottom of the moving block 1 26 is inside the T-shaped slide groove 2 31 When the adjusting rod 23 drops to the bottom, the moving block 1 26 is located at the outermost position, and the fixed block 1 27 extends to the outside of the fixed rod 1 7. At the same time, as the adjusting rod 23 rotates, the protruding block 33 on its outside rotates synchronously, and the protruding block 33 and the corresponding push plate 37 are misaligned. Under the action of the spring 3 40, the moving block 2 38 drives the fixed block 2 41 to move downward along the two guide rods 2 39. The bottom of the moving block 2 38 acts on the push plate 37, and the push plate 37 is forced to move to the side close to the protruding block 33. At this time, the fixed block 2 41 is retracted into the interior of the inner cylinder 34, and the fixed block 2 41 is disengaged from the positioning groove 2 36, thereby releasing the connection between the inner cylinder 34 and the outer cylinder 35.

[0041] Then, pull the two fixing rods 1 7 and the two fixing rods 2 8 to both sides respectively to unfold the whole body. After the unfolding is completed, the two fixing rods 1 7 are respectively inserted into the clamping ring 21 with a positioning groove 1 22, and the two fixing rods 2 8 are inserted into the other two clamping rings 21. When the two fixing rods 1 7 are fully inserted, under the action of the two springs 2 28, the two fixing blocks 1 27 are respectively inserted into the corresponding positioning groove 1 22, completing the fixation between the two fixing rods 1 7 and the two clamping rings 21, so that the two fixing rods 1 7 and the two fixing rods 2 8 are fixed to the top of the detection box 1.

[0042] When the charging gun is inserted into the interface module 3 for testing, first insert the port of the charging gun into the interface module 3 for a distance, and then use two pushing mechanisms to assist the charging gun to be fully inserted into the interface module 3, start the two cylinders 10, and drive the two T-shaped frames 11 to descend. At this time, the two T-shaped frames 11 drive their respective corresponding T-shaped sliders 12 to slide in the corresponding T-shaped slide grooves 15, and the two clamping blocks 14 are forced to drive the two limit sliders 16 on both sides to slide in the corresponding limit slide grooves 13. The two clamping blocks 14 slide inward at the same time to clamp the charging gun. The setting of the two rubber pads 17 has the effect of protecting the surface of the charging gun. When the two clamping blocks 14 completely clamp and fix the charging gun, as the two cylinders 10 continue to drive the T-shaped frame 11 to move downward, the two clamping blocks 14 also move downward synchronously, thereby causing the two connecting rods 9 to move along As they move downward along the two fixing rods 1 7 and the two fixing rods 2 8 respectively, the four springs 1 20 are squeezed, and the two clamping blocks 14 can drive the charging gun to be fully inserted into the interior of the interface module 3. The detection box 1 will directly display whether the charging pile is abnormal, and upload the detection results to the intelligent power distribution system, triggering an operation and maintenance work order or updating the health status of the pile body. After the detection is completed, through the upward movement of the two cylinders 10, the two clamping blocks 14 first drive the charging gun to be pulled out of the interface module 3, and then the two clamping blocks 14 move away from each other, thereby away from the charging gun, and the operation and maintenance personnel can easily remove the charging gun, which solves the problem in the prior art that the charging gun is slightly deformed due to collision with other objects, which makes it difficult to insert the charging gun into the interface module 3. The operation and maintenance personnel can easily insert or remove the charging gun into the interface module 3, which is also very labor-saving when detecting multiple charging piles.

[0043] After the detection work is completed, the two adjusting rods 23 are reversed, so that the two movable blocks 1 26 drive the two fixed blocks 1 27 to be retracted into the interior of the two fixed rods 1 7 respectively. At this time, the two movable blocks 2 38 drive the two fixed blocks 2 41 to extend out of the interior of the two inner cylinders 34 respectively, so that the two fixed rods 1 7 and the two fixed rods 2 8 can be directly taken out. By pushing the two fixed rods 1 7 and the two fixed rods 2 8, the two outer cylinders 35 slide respectively inside the two inner cylinders 34 until the two fixed blocks 2 41 correspond to the two positioning grooves 2 36. Under the action of the two springs 42, the two fixed blocks 2 41 are respectively inserted into the interior of the two positioning grooves 2 36, and the two outer cylinders 35 are respectively fixed between the two inner cylinders 34. The distance between the two fixed rods 1 7 and the two fixed rods 2 8 is fixed, which reduces the overall volume and is convenient to carry. The device can be stored in the storage box 6 through the provided storage box 6. The provision of three handles 4 and the provision of four rollers 5 make it convenient for operation and maintenance personnel to carry the DC charging pile detection device.
