One end of the electric push rod 73 is fixedly installed with a flexible brush plate 74.

[0022] When personnel use the auxiliary device for well flushing during downhole operations, the personnel can place the control box 1 in the downhole position. Subsequently, the personnel can connect the power supply of the electric push rod 73, so that the electric push rod 73 drives the flexible brush plate 74 to contact the downhole inner wall. Then, the power supply of the driving motor 31 is connected, so that the pulley 32 rotates. Subsequently, the belt 33 drives the driven wheel 34 to rotate. Immediately, the driven wheel 34 drives the connecting rod 71 to rotate, so that the flexible brush plate 74 quickly cleans along the downhole inner wall. Then, the personnel can use the diversion pipe 5 to connect to an external water source conveying device. Secondly, the water source is conveyed along the diversion pipe 5 to the inside of the spraying disc 62. Subsequently, the high-pressure nozzle 63 quickly flushes the water source to the downhole inner wall, so that the stubborn foreign matters on the downhole inner wall are quickly flushed, thus playing a role in facilitating the staff to quickly flush the foreign matters on the downhole inner wall.

Subsequently, the person can turn on the power supply of the electric push rod 73, so that the electric push rod 73 drives the flexible brush plate 74 to abut against the inner wall of the well. Subsequently, the power supply of the drive motor 31 is turned on, so that the pulley 32 rotates self - sufficiently. Subsequently, the belt 33 drives the driven wheel 34 to rotate. Immediately, the driven wheel 34 drives the connecting rod 71 to rotate, so that the flexible brush plate 74 quickly cleans along the inner wall of the well. Immediately, the person can connect the external water source conveying device by using the diversion pipe 5. Secondly, the water source is conveyed along the diversion pipe 5 to the inside of the spraying disc 62. Subsequently, the high - pressure nozzle 63 quickly flushes the water source to the inner wall of the well, so that the stubborn foreign matters on the inner wall of the well are quickly flushed, thus playing the role of facilitating the staff to quickly flush the foreign matters on the inner wall of the well.
