FREE-FALL TYPE CONE PENETROMETER HAVING VARIABLE STRUT PART

摘要

The present invention relates to a cone penetrometer (100), which freely falls in a perpendicularly erected state and penetrates a seabed ground so as to collect information of the seabed ground, comprising: a sensor part (1), which is provided at the lower end thereof and has a sensor embedded therein; a payload part (2), which is provided at the upper end thereof, and receives a signal and records the same; and a strut part (3) formed between the sensor part (1) and the payload part (2), wherein the strut part (3) has a structure, in which a plurality of strut modules (30) are continuously arranged and assembled in a disassemblable state, such that the strut part (3) can be formed through replacement with the strut module (30) having a thickness and a perpendicular length selected to be suitable for the softness of the seabed ground for which the cone penetrometer (100) is to penetrate.
