[0017] The present invention will be further described in detail below through specific embodiments:

[0018] The reference numerals in the accompanying drawings are as follows: 1-support rod, 2-fixed clamp, 3-movable clamp, 4-spring, 5-probe, 6-DC voltmeter, 7-sleeve, 8-pull rod, 9-connector, 10-pull rope, 11-slider, 12-slide groove, 13-arc plate.

[0019] like Figs. 1 to 3 The following describes a device for measuring the voltage at the short-circuit point of an electrolytic cell column busbar: a support rod 1 and a DC voltmeter 6. One end of the support rod 1 is threadedly connected to a fixed clamp 2, and the other end of the fixed clamp 2 is hinged to a movable clamp 3. A spring 4 is tied between the fixed clamp 2 and the movable clamp 3 with a wire. Probes 5 are fixedly connected to one end of both the fixed clamp 2 and the movable clamp 3. An arc-shaped plate 13 is bolted to the DC voltmeter 6, abutting against the support rod 1. The arc-shaped plate 13 and the support rod 1 are connected by a clamp. The DC voltmeter is model BY436VG. The probes 5 are electrically connected to the terminals of the DC voltmeter 6. The support rod 1, fixed clamp 2, and movable clamp 3 are all hollow. The structure facilitates the installation of the wires connecting the probe 5 and the DC voltmeter 6 inside the hollow structure. The support rod 1 is equipped with a movable component for opening and closing the movable clamp 3. The movable component includes a sleeve 7, the support rod 1 is slidably connected to the sleeve 7, a pull rod 8 is fixedly connected to the sleeve 7, a connector 9 is fixedly connected to the movable clamp 3, a pull rope 10 is tied between the connector 9 and the pull rod 8, a slider 11 is fixedly connected to the inner wall of the sleeve 7, a sliding groove 12 is opened on the support rod 1, and the slider 11 is slidably connected to the sliding groove 12. Both the fixed clamp 2 and the movable clamp 3 are made of insulating material, specifically polypropylene. One end of the support rod 1 is equipped with a handle, which is perpendicular to the support rod 1 to facilitate sliding the pull rod.

[0020] The implementation method of this embodiment is as follows: When it is necessary to measure the voltage at the short circuit point of the electrolytic cell column busbar, the operator first holds the handle of the support rod 1 and then pulls the pull rod 8. The pull rod 8 drives the sleeve 7 to slide on the support rod 1, and then pulls the movable clamp 3 open through the pull rope 10. Next, after aligning the fixed clamp 2 and the movable clamp 3 with the short circuit point of the busbar, the pull rod 8 is released. At this time, the spring 4 pulls the movable clamp 3 to close with the fixed clamp 2, tightly clamping the busbar, so that the probe 5 makes good contact with the busbar. Finally, the voltage of the electrolytic cell column busbar is transmitted to the DC voltmeter 6 through the probe 5, and the operator can directly read the voltage value on the DC voltmeter 6.

[0021] When it is necessary to adjust the position of DC voltmeter 6, the clamp can be loosened, and the position and angle of the arc plate 13 on the support rod 1 can be adjusted as needed, and then the clamp can be tightened again.

[0022] The above only is the embodiment of the present application, and the well-known specific structure and characteristics and other common knowledge in the scheme are not described too much here. It should be pointed out that, for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application.
