The rollers 11 can roll along the guide rail 20. An annular rack 13 is disposed on the periphery of the base 10, and a drive gear (not shown) is engaged with the rack 13 to drive the base 10 to rotate. Three power outlets 15 are mounted on the top of the base 10. The bottom of the base 10 extends downwardly from the power socket 15 to extend a plurality of brackets 16, each of which is provided with three positioning rods 161 for positioning the wires 60.

Referring to FIG. 3 together, the bottom end of the support rod 30 is fixed to the base 70, and the base 10 is rotatably coupled to the top end of the support rod 30. The support rod 30 defines three through holes 31 facing the conductive assembly 50. The base 70 defines a through hole 71 extending through the support rod 30.

Each of the conductive components 50 includes a barrel-shaped outer casing 51 fixed to the support rod 30, a receiving can 52 that is sleeved on the support rod 30 and is fastened between the outer casing 51 and the support rod 30, and is hollow. The conductive liquid 53 accommodated in the storage tank 52, the insulating oil layer 55 covering the upper surface of the conductive liquid 53, the annular cover 56, the three wires 60, one wire 80, and a conductive liquid testing device 57. The receiving can 52 is made of an insulating material such as plastic, and an annular opening 521 is formed on the upper side thereof. In the present embodiment, the conductive liquid 53 is mercury, and the insulating oil layer 55 can prevent volatilization of the conductive liquid 53. The cover body 56 is rotatably sleeved on the support rod 30 and covers the opening 521 of the receiving can 52 . The cover 56 defines a plurality of threading holes 562 through which the wires 60 pass.

The conductive liquid testing device 57 is configured to test whether the height of the conductive liquid 53 in the receiving tank 52 meets the requirements. The conductive liquid testing device 57 includes an L-shaped connecting tube 571 made of a transparent insulating material, from the housing 51. Two support plates 573 extending outward from both sides of the communication tube 571, a laser emitter 575 disposed at the end of one of the support plates 573, and disposed at the end of the other support plate 573 and facing the laser emitter 575 A laser receiver 576, an alarm 577, and a cable 578 connected between the alarm 577 and the laser receiver 576.

The communication tube 571 includes a first section 572 that passes through the bottom of the housing 51 and the receiving can 52, and a second section 574 that extends vertically upward from the outer end of the first section 572. The conductive liquid 53 in the storage can 52 can flow into the communication tube 571 through the first segment 572. The second section 574 is located between the laser emitter 575 and the laser receiver 576. When the conductive liquid testing device 57 is used, the laser emitter 575 emits a beam of light. If the conductive liquid 53 in the second section 574 of the communication tube 571 blocks the light, the laser receiver 576 cannot receive the beam. The light, the alarm 577 is normal, indicating that the amount of the conductive liquid 53 in the storage tank 52 meets the requirements; if the conductive liquid 53 in the second section 574 of the communication tube 571 does not block the light, the laser receiver 576 When the beam of light is received and the corresponding alarm light on the alarm 577 is alarmed, the amount of the conductive liquid 53 in the storage tank 52 is small, and the conductive liquid 53 needs to be added.

One end of each of the wires 60 is electrically connected to the conductive liquid 53 through the threading hole 562 of the cover 56 and the insulating oil layer 55. The other end of the wire 60 is connected to the power socket 15 on the base 10. Each wire 60 is wrapped with an insulating skin.

One end of the three electric wires 80 passes through the through hole 71 of the base 70 and the hollow portion of the support rod 30, and is inserted into the through hole 31 of the support rod 30 and connected to the conductive liquid 53 in the storage tank 52. The other end of the electric wire 80 is electrically connected to an external alternating current power source. In the present embodiment, each of the power sockets 15 is connected to three conductive wires 60 respectively inserted into the conductive liquid 53 in the three storage tanks 52. The three wires 80 are respectively connected to the live wire, the neutral wire and the ground wire of the AC power source.

In use, the mains is connected to the power outlet 15 of the base 10 by wires 80, conductive liquid 53 of the conductive assembly 50, and wires 60 to power the electronic devices on the base 10. The base 10 rotates to drive the bracket 16, the wire 60 and the cover 56 to rotate together, so that the cable strand during the rotation of the test turret does not occur.

In other embodiments, the sidewall of the second section 574 of the communication tube 571 is marked along the length of the second section 574 for indicating the height of the conductive liquid 53 in the storage can 52.
