Sea bed observation platform

The utility model relates to a seabed observation platform which is a seabed frame provided with an acoustics releaser. The utility model is an unit wholly opened style modular frame structure welded by corrosion resistant light weight metal pipelines; according to the observation technical requirement in blue water seabed or in shallow sea seabed, the module frames can be assembled into a floating body frame and/or observation frame with respective functions and characteristics by a knock-down assemble connecting unit which consists a long connecting buckling ring and a short connecting buckling ring. The platform can be directly used in blue water work and is also suitable for the application in shallow sea environment. The modular frame can be quickly assembled into different seabed observation platform structures by the connecting unit group, which makes a group of platform main body structures able to satisfy different practical application needs. So that, the utility model saves the making cost of the device, improves the service efficiency of the device, and enriches the methods of the modern sea researching techniques.
