A diving bell for draining the bottoms of bodies of water

A diving bell is a special device used for diving to great depths. It consists of a chamber or dome that is submerged underwater, providing access to the interior for divers.

The bell is typically tethered to the surface by cables and equipped with a life support system to sustain the divers inside it. This device allows work to be carried out on the seafloor or ocean floor without having to return to the surface, and is used in various fields, including deep-sea exploration, underwater construction, and underwater repair work.
