Description

Technical Field

[0001] This utility model relates to the field of low-voltage harmonic detection technology, and in particular to a low-voltage harmonic detection device. Background Technology

[0002] A low-voltage harmonic detection device is a specialized piece of equipment used to detect harmonic components in low-voltage power grids (generally referring to AC power grids with a rated voltage of 1000V and below). Harmonics refer to sinusoidal wave components in the power grid whose frequencies are integer multiples of the fundamental frequency (50Hz in my country's power system).

[0003] However, in existing technologies, data may become entangled inside some devices, and prolonged entanglement can cause physical damage to the data cable itself. The torque generated by the entanglement can cause the internal wires of the data cable to break or the insulation layer to be damaged. Once such damage occurs to the data cable, it will lead to the interruption of signal transmission. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a low-voltage harmonic detection device. This device ensures that the data line is in good condition, guarantees accurate and stable data transmission, and allows testing personnel to obtain reliable low-voltage harmonic information. This also facilitates internal inspection and maintenance, making maintenance work more convenient.

[0005] To achieve the above objectives, a low-voltage harmonic detection device is provided, comprising a detector, wherein a plurality of fixing blocks are fixedly connected inside the detector, a plurality of first springs are fixedly connected inside the fixing blocks, a sliding plate is fixedly connected to one end of each first spring, a limiting component for limiting mechanism and fixing is provided inside the fixing blocks, and a rubber sleeve is fixedly connected to the outside of the sliding plate.

[0006] According to the low-voltage harmonic detection device, the limiting component includes a second limiting hole, the outside of which is fixedly connected to the inside of the fixing block.

[0007] According to the low-voltage harmonic detection device, two telescopic rods are fixedly connected inside the fixed block, and one end of each telescopic rod is fixedly connected to the rear side of the sliding plate.

[0008] According to the low-voltage harmonic detection device, a first limiting block is fixedly connected inside the detector, and a plurality of first limiting holes are opened inside the first limiting block.

[0009] According to the low-voltage harmonic detection device, a housing cover is detachably connected to the rear side of the detector, a fixing plate is detachably connected to the rear side of the housing cover, and multiple knobs are rotatably connected inside the housing cover.

[0010] According to the low-voltage harmonic detection device, a rotating rod is fixedly connected to the rear side of the knob, and a second spring is sleeved on the outside of the rotating rod.

[0011] According to the low-voltage harmonic detection device, one end of the rotating rod is fixedly connected to a locking block, and a second limiting block is detachably connected to the outside of the locking block.

[0012] According to the low-voltage harmonic detection device, the detector has an internal display screen and multiple control buttons are fixedly connected to the outside of the detector.

[0013] Beneficial effects:

[0014] 1. Inside the detector is an anti-tangling data cable mechanism. The data cable can be placed on the surface of the fixed block. Then, pressing the rubber sleeve will compress the sliding plate fixed on the outside, which will compress the first spring inside. When the sliding plate is fully inserted into the groove inside the fixed block, it will slowly move into the second limiting hole. Then, slowly release the pressure so that one end of the sliding plate comes out of the second limiting hole, thereby fixing the data cable. This ensures that the data cable is in good condition, guarantees that the data can be transmitted accurately and stably, and allows the testing personnel to obtain reliable low-voltage harmonic information.

[0015] 2. When the data cable inside the detector is damaged, the knob on the outside of the cover can be rotated to make the rotating rod inside the knob drive the locking block to rotate inside the second limit block. When it is aligned with the groove of the second limit block, press the knob gently to compress the second spring, thereby pulling out the rotating rod and the locking block, and disassembling the cover. This facilitates the inspection and maintenance of the internal parts, making the maintenance work more convenient.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model provides a low-voltage harmonic detection device, which includes a detector 1. Multiple fixing blocks 7 are fixedly connected inside the detector 1 for fixing and supporting various types of components and structures. Multiple first springs 10 are fixedly connected inside the fixing blocks 7. A sliding plate 12 is fixedly connected to one end of each first spring 10 for supporting and sliding operations, allowing objects to move smoothly on its surface. A limiting component for limiting mechanism and fixing is provided inside the fixing blocks 7. A rubber sleeve 14 is fixedly connected to the outside of the sliding plate 12.

[0026] The limiting component includes a second limiting hole 13, which can limit the radial movement and rotation of the workpiece and ensure that the workpiece remains stable during processing. The second limiting hole 13 is externally fixedly connected to the inside of the fixing block 7.

[0027] The fixed block 7 has two telescopic rods 11 fixedly connected inside, and one end of the telescopic rod 11 is fixedly connected to the rear side of the sliding plate 12.

[0028] The detector 1 is internally fixedly connected to a first limiting block 8, which is used to ensure that the workpiece in the mold maintains an accurate position during the manufacturing process. The first limiting block 8 has multiple first limiting holes 9 inside.

[0029] The detector 1 is detachably connected to a cover 4 on the rear side, and a fixing plate 6 is detachably connected to the rear side of the cover 4. Multiple knobs 5 are rotatably connected inside the cover 4.

[0030] A rotating rod 15 is fixedly connected to the rear side of the knob 5, and a second spring 16 is sleeved on the outside of the rotating rod 15.

[0031] One end of the rotating rod 15 is fixedly connected to a locking block 17, which can restrict the movement of the workpiece and provide a guiding function to ensure that the workpiece moves along a predetermined path. A second limiting block 18 is detachably connected to the outside of the locking block 17.

[0032] The detector 1 has a display screen 2 inside and multiple control buttons 3 fixedly connected to the outside of the detector 1.

[0033] Working principle: Inside the detector 1 there is an anti-tangling data cable mechanism. The data cable can be placed on the surface of the fixing block 7. Then, the rubber sleeve 14 is pressed, which compresses the sliding plate 12 fixed on the outside and compresses the first spring 10 inside. When the sliding plate 12 is fully inserted into the groove inside the fixing block 7, it slowly moves into the second limiting hole 13. Then, it is slowly released, so that one end of the sliding plate 12 comes out from the second limiting hole 13, thereby fixing the data cable and fixing the other end of the data cable in the first limiting hole 9 inside the first limiting block 8.

[0034] When the data cable inside the detector 1 is damaged, the knob 5 on the outside of the cover 4 can be rotated to make the rotating rod 15 inside the knob drive the locking block 17 to rotate inside the second limiting block 18. When it is aligned with the groove of the second limiting block 18, gently press the knob 5 to compress the second spring 16, thereby pulling out the rotating rod 15 and the locking block 17, and disassembling the cover 4. This makes it convenient to maintain and replace the data cable.
