The utility model provides a non metallic member's large -scale seabed measuring platform, belongs to the ocean surveying and ocean engineering equips technical field. This ocean measuring platform includes logical board, lower logical board, cross slab, bracing and the gasbag etc. Of intersecting indulged from north to south. Fully consider ocean measuring platform's practical application requirement to and technological and economic nature overall balance, adopt glass fiber reinforced plastic material, upward indulge logical board and provide good operational environment for the instrument, upward indulge and lead to the board and be connected by the cross slab between the logical board from north to south down to by alternately bracing reinforcement, structural style is both simple novel, has guaranteed vertical bending strength again, come the control platform heave through adjustment gasbag aeration quantity, setting up the hoisting point on the cross slab of both ends, being equipped with the transportation by driving platform in addition and helping the operation, it is controllable to ensure that this platform sinks the process, strikes the damage to the structure when avoiding the platform to sit the end in the twinkling of an eye. This measuring platform manufacturing process is simple, and the function is perfect, and antimagnetic nature is good, anti rotten can the reinforce, be formula ocean measuring platform at the bottom of reliable, the high -efficient and economic seat.
