Abstract

The present invention relates to a pressure-resistant spherical low-speed vertical lift type underwater camera apparatus. The vertical lift type underwater camera apparatus according to the present invention is small, simple in construction, and inexpensive. Because the underwater camera apparatus is small and wirelessly operated, exploration is performed by dropping multiple underwater camera apparatuses in various areas and then collecting them that float to the surface after filming is completed. Thus, the underwater camera apparatus can photograph the underwater conditions of a large area with a single expedition. It is durable enough to withstand high water pressure, thereby providing the effect of enabling deep-sea photography.

Description

The present invention relates to a pressure-resistant vertically elevating underwater camera device.

In order to observe or photograph the underwater state in the sea, a diver is usually submerged with an underwater camera and photographed. However, in the case of the deep seabed, which exceeds the physiological limit of human diving depth, it is impossible for a diver to dive, so an underwater camera device must be put in to take a picture.

Such an underwater camera device must be capable of taking pictures in a harsh deep-sea environment where high water pressure and natural light cannot reach. Therefore, the underwater camera device must be designed to be waterproof and have durability that can withstand high water pressure and low temperature, and a lighting device is essential.

Since the underwater camera device must transmit shooting information to the ground and collect it again after shooting is finished, it is mainly driven while connected to a floating body on the surface of the water through a cable. The deep-sea state is photographed, and the captured image and deep-sea information are sent to the ground through a cable connected to the camera device. On the ground, the image and information are used to determine the deep-sea state and to study the deep sea or develop deep-sea resources.
