Title:
UNDERWATER PHOTOGRAPHING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/109848
Kind Code:
A1
Abstract:
Provided is an underwater photographing apparatus, comprising a driving transmission box (1), a driven transmission box (2) and a waterproof camera (10) which are connected in sequence, and further comprising a second magnet (7) arranged in the driven transmission box (2), and a power supply (22), a motor (5) and a first magnet (6) which are arranged in the driving transmission box (1) and are connected in sequence, with the driving transmission box (1) being of a completely sealed structure. By means of magnetic coupling of the first magnet (6) and the second magnet (7), the underwater photographing apparatus can realize force and torque transmission between the driving shaft (9) and the driven shaft (8) without direct contact, so that dynamic sealing of the driving transmission box (1) can be converted into static sealing, thereby realizing zero-leakage, and improving the waterproof function.
