Submarine survey platform and method for using the same

A submarine survey platform, comprising:

• a gasbag;
• a gas tube;
• a floater;
• an upper longitudinal plate;
• a lower longitudinal plate;
• diaphragm plates, the diaphragm plates comprising upper openings, lower openings, and trapezoid openings disposed between the upper openings and the lower openings;
• and
• diagonal braces;
• wherein
• the upper longitudinal plate comprises a flat plate adapting to support measuring instrument, and a flanged plate;
• the lower longitudinal plate is a rectangular plate;
• the upper longitudinal plate pass through the upper openings, and the lower longitudinal plate pass through the lower openings;
• the diagonal braces and longitudinal stiffeners are disposed between every two adjacent diaphragm plates;
• two diaphragm plates respectively disposed at two ends of the flat plate are provided with a lifting lug;
• the diagonal braces are symmetrically disposed, and comprise outward braces and inward braces which are crossed with each other;
• cross points of the upper/lower longitudinal plate with the diaphragm plates are support points of the upper/lower longitudinal plate;
• the gasbag is disposed in and passes through each of the trapezoid openings;
• one end of the gasbag is connected to the gas tube;
• another end of the gas tube is provided with an air valve, and the air valve is attached to the floater;
• the diaphragm plates are a trapezoidal frame, four edges of the diaphragm plates comprise first flanged plates, and the trapezoid openings are surrounded by second flanged plates;
• the diagonal braces employ trough type members, cross points of the outward braces and the inward braces are reinforced using bolt and nuts;
• and
• the longitudinal stiffeners are symmetrically disposed at a bottom of the lower longitudinal plate, and are a right-angle structure connected to the lower longitudinal plate and the diaphragm plates.
