Description

Technical Field

[0001] This utility model relates to the field of resonance testing technology, and more specifically, to a series resonance testing device. Background Technology

[0002] In power systems, series resonant test devices are key equipment for testing the insulation performance of electrical equipment. Large electrical equipment, such as high-voltage cables and complete sets of equipment in substations, are bulky and heavy, and cannot be disassembled and transported to a fixed laboratory for testing. The tests must be carried out on-site. Therefore, the series resonant test device needs to be moved to the site where the equipment is located in order to complete the wiring, debugging and testing operations. Because the series resonant test device is large and inconvenient to move, the complex ground conditions may cause bumps during the movement.

[0003] However, the series resonance test devices commonly available on the market have many limitations. The devices are generally large in height and volume, and when they are difficult to move in complex terrain or narrow spaces, they need to be adjusted to be horizontal, tilted, or vertical in order to enter a small doorway. Therefore, a more efficient, stable, and flexible series resonance test device is needed. Utility Model Content

[0004] This invention addresses the technical problems existing in the prior art by providing a series resonance test device.

[0005] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: It includes an adjustment component, wherein a pair of symmetrical clamping components are provided in the middle of the adjustment component, and a pair of symmetrical moving components are provided at the lower end of the adjustment component; The adjustment assembly includes a main housing, a rotating shaft rotatably connected to the middle of the main housing, a worm gear fixedly connected to the middle of the rotating shaft and inside the main housing, a first servo motor fixedly connected inside the main housing, a worm fixedly connected to the output end of the first servo motor, and the worm meshing with the worm gear.

[0006] Furthermore, the clamping assembly includes a C-shaped fixing frame fixedly connected to one end of the rotating shaft. A second servo motor is fixedly connected to one end of the C-shaped fixing frame. A bidirectional lead screw is rotatably connected to the output end of the second servo motor. A fixing rod is fixedly connected inside the C-shaped fixing frame. A pair of symmetrical hinge blocks are fixedly connected to one end of the fixing rod. A clamping ring is hinged to one end of each pair of hinge blocks. The lead screw surface has two sections of threads with opposite directions of rotation, which cooperate with the drive blocks. When the lead screw rotates, it can drive the two drive blocks to move simultaneously in opposite directions, thereby controlling the opening and closing of the clamping rings through the hinge rod.

[0007] Furthermore, the C-shaped fixing frame has a pair of symmetrically slidably connected internally. One end of each pair of driving blocks is hinged to a hinge rod, which is then hinged to the middle of a pair of clamping rings. The component directly in contact with the workpiece achieves a circumferential clamping action on the workpiece through its own rotation. Its shape is adapted to the workpiece's shape, such as a round workpiece, increasing the contact area, dispersing pressure, and preventing damage to the workpiece.

[0008] Furthermore, the movable component includes two pairs of fixed outer shells fixedly connected to the middle of the main body shell. A hydraulic buffer rod is fixedly connected inside each fixed outer shell. An L-shaped support rod is fixedly connected to the upper end of each hydraulic buffer rod. A movable mounting plate is fixedly connected to the middle of each pair of L-shaped support rods. A pair of symmetrical movable wheels are fixedly connected to the lower end of each movable mounting plate, serving as a buffer and support mechanism. When the equipment is moved or placed, it can absorb vibrations such as bumps caused by uneven ground through its own extension and retraction, reducing the impact on the main structure. Simultaneously, it supports the weight of the L-shaped support rods and the components above, and adjusts the height of the movable wheels.

[0009] Furthermore, the worm gear is hollowed out, which can effectively reduce the weight of the entire device and make it relatively lightweight.

[0010] Furthermore, a limiting protrusion is fixedly connected to the other end of the drive block, which cooperates with the limiting groove for sliding limitation.

[0011] Furthermore, the C-shaped fixing frame has a limiting groove inside that slides with the limiting protrusion, which limits the movement of the driving block when it slides.

[0012] Furthermore, the fixing rod has a circular hole in the middle for the bidirectional lead screw to pass through, which facilitates installation and ensures that the entire structure operates without conflict.

[0013] The beneficial effects of this utility model are: In the adjustment assembly, the first servo motor drives the worm gear to rotate, which meshes with the worm wheel to drive the rotating shaft to rotate, thereby realizing the angle adjustment of the test sample connected to the rotating shaft. It facilitates transportation laterally and testing operation vertically, and no manual adjustment is required. In the moving assembly, the hydraulic buffer rod inside the fixed housing can effectively absorb the impact force from the ground during the movement of the device. Together with the L-shaped support rod and the moving wheels, the device can be easily moved in complex terrain or confined spaces. At the same time, the shock absorption effect of the hydraulic buffer rod can reduce the damage to the internal precision components caused by bumps during movement, extend the service life of the device, and improve the stability and reliability of the equipment.
