[0032] Reference Figures 1 to 3 , the present invention provides a technical solution: a high-efficiency generator collector ring carbon brush grinding control system, including: a live wire L, a neutral wire N, a state display module 1, a control switching module 2, a grinding component 3, and a stroke component 4;

[0033] The power supply end of the status display module 1 is connected to the live wire L, and the load end is connected to the neutral wire N, for displaying the working status of the system; the control switching module 2 is arranged in parallel with the status display module 1 in the circuit, and its power supply end is connected to the live wire L, and its load end is connected to the neutral wire N, for controlling the status of the travel component 4; and

[0034] The grinding component 3 is connected to the control switching module 2 and is used to adjust the rotation speed of the brush head; the stroke component 4 is connected to the control switching module 2 and is used to adjust the reciprocating grinding stroke spacing and speed of the brush head.

[0035] A power switch S1 and a power switch S2 are respectively provided between the live line L, the neutral line N and the power distribution line.

[0036] As a preferred embodiment, a start button TA is provided at the connection point between the power supply end of the control switching module 2 and the live wire L.

[0037] As a preferred embodiment, a starting contactor KM3 is provided at the power supply end where the control switching module 2 is connected to the polishing assembly 3, and a starting contactor KM4 is provided at the load end.

[0038] The parameters of the control switching module 2 are adjusted according to the specifications of the carbon brushes, so that the control switching module 2 controls the stroke component 4 and performs cyclic grinding of the carbon brushes, thereby improving the grinding effect and efficiency of the carbon ring.

[0039] When grinding the carbon brush of the collector ring:

[0040] Close the power switch S1 and the power switch S2, and the indicator light HL1 will light up, which means that the power supply line is in normal power supply state. If the indicator light HL1 is not lit, it means that the power supply line is abnormal and needs to be repaired.

[0041] When the indicator light HL1 is on, press the start button TA to supply normal power to the control switching module 2. In this state, the starting contactors KM1, KM3 and KM4 are automatically closed to make the entire circuit conductive. At the same time, the indicator light HL2 is on, indicating that under the control of the control switching module 2, the stroke component 4 switches the grinding stroke and direction of the carbon brush according to the set parameters, thereby achieving the effect of cyclic grinding. After the grinding is completed, press the stop button 5 to end the grinding state. At the same time, after pressing the stop button 5, the circuit is interrupted, that is, the indicator light HL2 goes out.

[0042] By adjusting the grinding component 3, the rotation speed of the brush head can be changed, that is, the grinding force of the brush head on the carbon brush can be changed, and the staff can make adjustments at any time during the grinding process to avoid insufficient or excessive grinding.

[0043] Repeat the above operation to grind the carbon brushes in batches. The carbon brushes after grinding are standard parts, which can form a perfect arc with a fixed radius to ensure the fit with the collector ring.

[0044] It should be noted that when the grinding component 3 or the stroke component 4 fails and cannot be started correctly, the starting contactor KM3 is disconnected from the starting contactor KM4, that is, the power supply circuit to the grinding component 3 or the stroke component 4 is disconnected to prevent a short circuit from occurring and causing damage to the equipment.

[0045] As a preferred embodiment, the controlled switching module 2 includes: a stop button 5, a start contactor KM2, an intermediate relay KA1, an intermediate relay KA2, and a travel switch SQ2;

[0046] The power supply end of the stop button is connected to the start button TA, the upper interface of the load end is connected to the neutral line N through the start contactor KM2, the lower interface of the load end is connected to the neutral line N through the intermediate relay KA1, and a converter is arranged between the lower port and the intermediate relay KA1, and the first adjustment component and the second adjustment component are arranged in parallel in the converter.

[0047] As a preferred embodiment, the first adjustment component includes: a travel switch SQ1, a circuit breaker QF2, and a circuit breaker QF1;

[0048] The power supply end of the travel switch SQ1 is connected to the stop button, the upper interface of the load end is connected to the power supply end of the intermediate relay KA1, and the circuit breaker QF2 and the circuit breaker QF1 are arranged in series on the connection line between the upper interface of the load end of the travel switch SQ1 and the intermediate relay KA1;

[0049] The lower interface of the load end of the travel switch SQ1 is connected to the second adjustment component.

[0050] As a preferred embodiment, the second regulating component includes: a travel switch SQ2, a circuit breaker QF3, a circuit breaker QF4, and an intermediate relay KA2;

[0051] The power supply end of the travel switch SQ2 is connected to the stop button, the upper interface of the load end is connected to the lower interface of the load end of the travel switch SQ1, and the circuit breaker QF3 and the circuit breaker QF4 are arranged in series on the connection line between the upper interface of the load end of the travel switch SQ2 and the lower interface of the load end of the travel switch SQ1;

[0052] The lower interface of the load end of the travel switch SQ2 is connected to the power end of the intermediate relay KA1; the power end of the intermediate relay KA2 is connected to the circuit breaker QF4, and the load end is connected to the starting contactor KM4.

[0053] It should be noted that by adjusting the travel switch SQ1 and the travel switch SQ2, and coordinating the changes in the line signals by the intermediate relays KA1 and KA2, the moving speed and the round-trip distance of the travel component 4 can be controlled, that is, by controlling the travel component 4, the relative dwelling gap of the grinding component 3 to the carbon brush grinding area can be changed, while ensuring the grinding effect, preventing excessive grinding, and in the process of reciprocating grinding of the carbon brush, ensuring the grinding effect of the grinding component 3, avoiding excessive grinding, and ensuring the grinding effect.

[0054] As a preferred embodiment, the grinding assembly includes: a power switch S3, a vacuum cleaner M1, an AC speed regulator, and a rotating motor M2;

[0055] The vacuum cleaner M1 and the AC speed regulator are connected in parallel to the control switching module 2, and a power switch S3 is provided in series on the connection line between the vacuum cleaner M1 and the switching module 2; the rotary motor M2 is connected to the AC transmission.

[0056] It should be noted that by changing the control current of the AC speed regulator, the speed of the rotating motor M2 is changed, thereby changing the speed of the brush head connected to the rotating motor M2, that is, the grinding speed is adjusted during the grinding process, thereby improving the grinding effect of the brush head on the carbon brush.

[0057] During the grinding process, the power switch S3 can also be turned on to start the vacuum cleaner M1 to absorb and collect the residues generated by the grinding carbon brush to prevent the residues from causing wear and scratches on the surface of the carbon brush during the grinding process, thereby improving the grinding effect. At the same time, it can also prevent the residues from being inhaled into the nasal cavity of the staff, ensuring that the staff is in a safe working environment.

[0058] As a preferred embodiment, the stroke component 4 includes: a single-phase transformer, a rectifier 6, a DC speed regulator, and a brush head stroke motor M3;

[0060] The power supply end of the DC speed regulator is connected to the rectifier, and the load end is connected to the brush head stroke motor M3. An intermediate relay KA3 and an intermediate relay KA4 are respectively provided on the connection circuit between the DC speed regulator and the positive and negative poles of the brush head stroke motor M3.

[0061] The voltage of the current is changed through a single-phase transformer to meet the working voltage requirement of the brush head stroke motor M3. At the same time, under the action of the rectifier 6, the AC current changed by the single-phase transformer is converted into DC current for use by the brush head stroke motor M3, thereby ensuring the accuracy of the mobile grinding rate and the accuracy of the reciprocating formation, effectively reducing the control cost while improving the control effect.

[0062] It should be noted that intermediate relays KA3 and KA4 and a DC speed regulator are set at the positive and negative poles of the brush head stroke motor M3. Through the signal interaction between the intermediate relays KA3 and KA4 and the control switching module 2, the stroke motor M3 can accurately control the reciprocating distance of the brush head, and the reciprocating grinding rate can be adjusted by the DC speed regulator.

[0063] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
