[0002] With the popularization of electric vehicles, the number of charging piles is gradually increasing. The power quality monitor can regularly record and store the changing trends of power parameters such as voltage, current, active power, reactive power, frequency, phase, etc. of the charging piles.

[0003] In recent years, new charging piles have been equipped with power quality monitors, such as the charging pile disclosed in the patent number CN220947637U, entitled "A charging pile with power quality monitoring function". However, the charging piles installed in the early stage did not have this function, and there was no reserved position and installation components for the additional installation of the power quality monitor. Utility Model Content

[0004] The purpose of the utility model is to provide a device for supplementing the installation of a power quality monitor on a charging pile, so as to solve the deficiencies in the above-mentioned prior art.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for supplementing a power quality monitor for a charging pile, comprising a fixed frame, the fixed frame is fixedly connected to one side of the charging pile, a slide plate is slidably connected to the fixed frame, a clamping assembly for clamping and fixing the power quality monitor is provided on the slide plate, a locking assembly is provided between the fixed frame and the slide plate, the locking assembly comprises a U-shaped clip arranged on the slide plate, a wedge block slidably connected to the fixed frame, and a spring arranged between the wedge block and the fixed frame.

[0006] Furthermore, the locking assembly also includes an L-shaped rod and a limit rod. The L-shaped rod is fixedly connected to the wedge block, and the limit rod is slidably connected to the fixed frame. When the wedge block locks the slide plate and needs to be unlocked to inspect the power quality monitor, the L-shaped rod is pulled and the L-shaped rod will drive the wedge block to move horizontally. The wedge block will squeeze the spring while moving horizontally, and the spring has a tendency to restore the deformation and needs to fix the L-shaped rod. At this time, the limit rod needs to be slid a certain distance so that the limit rod can abut the L-shaped rod. At this time, the L-shaped rod and the limit rod form a U-shape.

[0007] Furthermore, the locking assembly also includes an L-shaped rod and a limit rod. The L-shaped rod is rotatably connected to the wedge block, and the limit rod is fixedly connected to the fixed frame. When the wedge block locks the slide and needs to be unlocked to inspect the power quality monitor, the L-shaped rod is pulled and the L-shaped rod will drive the wedge block to move horizontally. The wedge block will squeeze the spring while moving horizontally, and the spring has a tendency to restore deformation. At this time, the L-shaped rod is rotated and the limit rod can abut against the L-shaped rod, and the limit rod and the L-shaped rod form a U shape.

[0008] Furthermore, the clamping assembly includes a baffle, two parallelly arranged clamping plates and a driving unit. The baffle is fixedly connected to a side of the skateboard away from the charging pile, and the two clamping plates are slidably connected to the skateboard. The driving unit includes a bidirectional screw and two nuts. The bidirectional screw is rotatably connected to the skateboard, and the two nuts are fixedly connected to the two clamping plates one by one. The bidirectional screw has two threaded sections with opposite rotation directions, and the two nuts are threadedly connected to the two threaded sections one by one. When the power quality monitor needs to be fixed on the skateboard, the power quality monitor needs to be placed on the skateboard first and then the power quality monitor is abutted against the baffle. At this time, the bidirectional screw is rotated. The rotation of the bidirectional screw will cause the nut on the bidirectional screw to move, and the movement of the nut will move with the clamping plate. At this time, the two clamping plates move closer to the power quality monitor and finally the two clamping plates abut the power quality monitor. At this time, the power quality monitor can be more stably installed on the skateboard. At the same time, the clamping assembly can also clamp and fix power quality monitors of different models.

[0009] Furthermore, a handle is fixedly connected to the side of the baffle away from the charging pile, which is convenient for workers to pull out the slide plate to repair and maintain the power quality monitor.

[0010] In the above technical scheme, the utility model provides a device for supplementing the installation of a power quality monitor for a charging pile, wherein the power quality monitor is placed on a slide board and fixedly clamped by a clamping assembly on the slide board, and then the slide board with the power quality monitor is slid into a fixed frame and the slide board is locked by a locking assembly so that the power quality monitor is firmly installed in the fixed frame. On the one hand, the fixed frame and the slide board on the charging pile reserve a position and structure for installing the power quality monitor, and on the other hand, the power quality monitor enables the charging pile to have a power quality monitoring function.

When the slide plate 2 moves toward the charging pile 11 again, there is a moment when the U-shaped clamp 22 can no longer abut the wedge block 12. At this time, the wedge block 12 is subjected to the horizontal elastic force of the spring 13, so that the wedge block 12 enters the recess of the U-shaped clamp 22, and then the locking assembly locks the slide plate 2 and fixes the slide plate 2. At this time, the fixed frame 1 provides space for installing the power quality monitor 21, and the clamping assembly and the lock can gradually fix the power quality monitor 21 to the fixed frame 1. In addition, the U-shaped clamp 22 will only generate an abutting force when it contacts the wedge block 12, and the U-shaped clamp 22 can effectively avoid friction between the wedge block 12 and the slide plate 2 compared to the slide plate 2, thereby protecting the slide plate 2.

[0022] In the above technical scheme, the utility model provides a device for supplementing the installation of a power quality monitor for a charging pile, wherein the power quality monitor 21 is placed on a slide plate 2 and fixedly clamped by a clamping assembly on the slide plate 2, and then the slide plate 2 with the power quality monitor 21 is slid into a fixed frame 1 and the slide plate 2 is locked by a locking assembly so that the power quality monitor 21 is firmly installed in the fixed frame 1. On the one hand, the fixed frame 1 and the slide plate 2 on the charging pile 11 reserve a position and structure for installing the power quality monitor 21, and on the other hand, the power quality monitor 21 enables the charging pile 11 to have a power quality monitoring function.

[0023] As the preferred technical solution of this embodiment, the locking assembly also includes an L-shaped rod 121 and a limit rod 14. The L-shaped rod 121 is fixedly connected to the wedge block 12, and the limit rod 14 is slidably connected to the fixed frame 1. When the wedge block 12 locks the slide plate 2 and needs to be unlocked to inspect the power quality monitor 21, the L-shaped rod 121 is pulled and the L-shaped rod 121 will drive the wedge block 12 to move horizontally. The wedge block 12 will squeeze the spring 13 while moving horizontally, and the spring 13 has a tendency to restore deformation and needs to fix the L-shaped rod 121. At this time, the limit rod 14 needs to be slid a distance so that the limit rod 14 can abut against the L-shaped rod 121. At this time, the L-shaped rod 121 and the limit rod 14 form a U shape.

[0024] In another embodiment provided by the utility model, the locking assembly also includes an L-shaped rod 121 and a limit rod 14. The L-shaped rod 121 is rotatably connected to the wedge block 12, and the limit rod 14 is fixedly connected to the fixed frame 1. When the wedge block 12 locks the slide plate 2 and needs to be unlocked to inspect the power quality monitor 21, the L-shaped rod 121 is pulled and the L-shaped rod 121 will drive the wedge block 12 to move horizontally. The wedge block 12 will squeeze the spring 13 while moving horizontally, and the spring 13 has a tendency to restore deformation. At this time, the L-shaped rod 121 is rotated. At this time, the limit rod 14 can abut against the L-shaped rod 121, and the limit rod 14 and the L-shaped rod 121 form a U shape.

[0025] As the preferred technical solution of this embodiment, the clamping assembly includes a baffle 23, two parallel clamping plates 3 and a driving unit. The baffle 23 is fixedly connected to the side of the skateboard 2 away from the charging pile 11. The two clamping plates 3 are slidably connected to the skateboard 2. The driving unit includes a bidirectional screw 4 and two nuts 41. The bidirectional screw 4 is rotatably connected to the skateboard 2. The two nuts 41 are fixedly connected to the two clamping plates 3 in a one-to-one correspondence. The bidirectional screw 4 has two threaded sections with opposite rotation directions. The two nuts 41 are threadedly connected to the two threaded sections in a one-to-one correspondence. When it is necessary to fix the power quality monitor 21 on the skateboard 2 When the power quality monitor 21 is mounted on the slide 2, it is necessary to first place the power quality monitor 21 on the slide 2 and then make the power quality monitor 21 abut against the baffle 23. At this time, the bidirectional screw rod 4 is rotated. The rotation of the bidirectional screw rod 4 will cause the nut 41 on the bidirectional screw rod 4 to move, and the movement of the nut 41 will move with the clamping plate 3. At this time, the two clamping plates 3 move closer to the power quality monitor 21 and finally the two clamping plates 3 abut against the power quality monitor 21. At this time, the power quality monitor 21 can be more firmly installed on the slide 2, and the clamping assembly can also clamp and fix different models of power quality monitors 21.
