· The editor takes you to understand the wide range of underwater camera applications

2023-04-24

Underwater cameras are mainly used to capture underwater images. The camera can be directly used in water through waterproof treatment, and the photographer can operate the camera from the ship. The image signal is transmitted to the monitor through a cable and recorded on a magnetic tape. Due to the weak light at the bottom of the water, multiple infrared light emitting diodes are generally installed around the camera, ensuring its normal operation.

· What are the basic functions of underwater thrusters

2022-10-19

Underwater thruster is one of the key equipment for underwater vehicles and sewage flow. It follows the Conservation of energy and converts the energy carried by the underwater vehicle into the mechanical energy necessary for driving the vehicle to carry out related movements on the basis of the relevant energy conversion principle. When underwater thrusters move underwater, they are subject to water resistance.
