[0032] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation modes in conjunction with the accompanying drawings.

[0033] Please refer to Figures 1 to 3 , the utility model provides a shaft current conducting device for electromechanical equipment, comprising a connecting plate 1 and a brush holding mechanism 2;

[0034] The brush holding mechanism 2 is provided with two groups, which are symmetrically arranged on the connecting plate 1. The brush holding mechanism 2 includes a rectangular housing 21, a grounding wire 26, a carbon brush 25, a connecting seat 23 and a spring 22;

[0035] The rectangular shell 21 is a rectangular shell with an opening at the bottom, and both side walls of the rectangular shell 21 are provided with strip-shaped guide holes 24;

[0036] The connecting seat 23 is slidably installed in the rectangular housing 21, and connecting blocks extending from the strip-shaped guide holes 24 are provided at both ends of the connecting seat 23;

[0037] The carbon brush 25 is fixed on the connecting seat 23.

[0038] The spring 22 is installed in the rectangular housing 21, one end of the spring 22 is connected to the connecting seat 23, and the other end of the spring 22 is connected to the top of the inner wall of the rectangular housing 21;

[0039] One end of the grounding wire 26 is connected to the carbon brush 25, and one end of the grounding wire 26 is passed through the rectangular housing 21 and is grounded;

[0040] When in use, during the operation of the motor, the shaft current generated is guided into the brush holding mechanism 2, and under the action of the spring 22, the carbon brush 25 can maintain stable contact with the grounding ring on the motor, which is beneficial to the stable and safe conduction of the shaft current.

[0041] In this embodiment, an early warning mechanism 3 is further included. The early warning mechanism 3 is installed on the connecting plate 1. When the carbon brush 25 is worn to a certain extent, the early warning mechanism 3 sends out an early warning signal.

[0042] The warning mechanism 3 includes a battery 33, a signal light 32, a single chip microcomputer and a touch sensor 34;

[0043] The rectangular housing 21 has protruding blocks 35 disposed opposite to each other on both sides of the opening;

[0044] The touch sensor 34 is installed on the surface of the protruding block 35, and when the connecting block moves to the terminal end of the strip-shaped guide hole 24, it contacts the touch sensor 34;

[0045] The battery 33 is connected to the signal light 32 , the single chip microcomputer and the touch sensor 34 in sequence.

[0046] Wherein, the warning mechanism 3 further includes a buzzer 31, and the buzzer 31 is electrically connected to the single chip computer;

[0049] The working principle of the utility model is as follows:

Under the action of the spring 22, the carbon brush 25 can maintain stable contact with the grounding ring on the motor, which is beneficial to the stable and safe conduction of the shaft current. When the carbon brush 25 is worn to a certain extent, the early warning mechanism 3 serves as a timely warning to avoid serious wear of the carbon brush 25, which causes its contact resistance to increase, thereby affecting the current extraction problem.
