The invention discloses an electrode wall surface micro-pit electrolysis micro-bubble generating device based on micro-drill drilling, and relates to the technical field of active drag reduction of underwater vehicles. The device comprises a base body, a carbon rod and a voltage-stabilized direct-current power supply, the surface of the base body is provided with an electrode wall surface micro-pit structure, a polyimide coating is laid on the upper surface of the base body, the lower surface of the base body is connected with a negative electrode of the voltage-stabilized direct-current powersupply through a power lead, and the carbon rod is connected with the negative electrode of the voltage-stabilized direct-current power supply. By electrolyzing a NaCl solution, self-adaptive controlover microbubble growth can be achieved, gas does not need to be continuously introduced for a long time, when microbubbles are broken or fall off or a gas-liquid interface is lower than a laid polyimide coating, the device automatically triggers an electrolysis circuit, self-adaptive control over the microbubbles is achieved, and the device is suitable for surface ships and underwater vehicles.Micro-bubbles can be stably maintained, and practical engineering and military application are facilitated.
