摘要： Image recording as long as possible during one activity is required in deep sea exploration. Necessity of multi-directional image recording, optical and chemical observations and probing of mineral resources of seabed are also increased. There is no underwater exploration device enable these requirements. It is disclosed that at least one battery-driven underwater exploration body having three pressure-resistant hollow glass spheres for housing an image capturing device, an illumination device, a recording device, an acoustic communication device and a control device controlling thereof and at least one battery body having an approximately the same shape and structure as the underwater exploration body are connected with each other by a connecting tool to provide the connectedly-formed underwater exploration device.

摘要： Provided with a weight release device capable of being operated in deep sea same as the conventional weight release device without accompanying a mechanical operation at all to avoid troubles of mechanical operation occurred in the conventional weight release device. The weight release device includes a housing fixed to the underwater observation device; a thread made of thermoplastic resin; electric heater portions; a weight support plate; a locking member of the thread made of the thermoplastic resin; and a ring for hanging the weight. The thread made of the thermoplastic resin is arranged from a start point housed in the housing, arranged to pass through the first electric heater portion, locked to the locking member of the thread made of the thermoplastic resin, arranged to pass through the second electric heater portion housed in the housing, and returned to an end point housed in the housing. The ring for hanging the weight is fixed to a lower surface of the weight support plate. The weight is released only by conducting an electricity through the electric heater portion to release the weight for floating the underwater observation device.
