Underwater sensor protection device and method employed thereof

An underwater sensor protection device, comprising:

• at least three focal tubes connected to at least one control board, the at least three focal tubes comprise open ends are kept open and closed ends are connected to the at least one control board;
• at least three air pumps and at least three solenoid valves are connected to the at least one control board, whereby the at least one control board is configured to control an operation of at least three sensors and the at least three sensors contact with the water level, the at least three focal tubes are submerged in water level for regulating the at least three pumps;
• at least one air tube is connected to the at least one air pump and the at least one air tube is positioned in the at least one focal tube, air is passed through the at least one air tube to the at least one focal tube and vacates the volume of water within the at least one focal tube for avoiding water contact with the at least one sensor;
• and
• a plurality of air bubbles is generated by passing air via the at least one air tube for longer duration into the at least one focal tube thereby performing cleaning operation of the at least three sensors.

A method, comprising:

• submerging at least one focal tube in water level, whereby the at least one focal tube comprises at least one open end is kept open and at least one top closed end is connected to at least one control board;
• regulating at least one air pump in a periodic manner by at least one solenoid valve, whereby the at least one solenoid valve and the at least one air pump are connected to the at least one control board and the at least one control board is configured to control and operation of a plurality of sensors and the plurality of sensors contact with the water level;
• passing air through at least one air tube to the at least one focal tube and vacating the volume of water within the at least one focal tube for avoiding water contact with the plurality of sensors, the at least one air tube is connected to the at least one air pump and the at least one air tube is positioned in the at least one focal tube;
• and
• generating a plurality of air bubbles by passing air via the at least one air tube for longer duration into the at least one focal tube thereby performing cleaning operation of the plurality of sensors.
