With the continuous deepening of people's development and utilization of marine biological resources, seabed mineral resources, and marine energy, the number of seabed environmental monitoring instruments and engineering application instruments deployed to the seabed is gradually increasing, and the recycling of marine equipment is also of paramount importance. In this way, an underwater acoustic release device has emerged.The underwater acoustic release device is mainly used for automatic recovery of underwater equipment. It sends remote release instructions through the deck unit, and the response release device receives the command and verifies it. After the verification is correct, the release mechanism is opened and disconnected from the gravity anchor. The response release device and equipment float out of the water surface under buoyancy, and then recover.This device mainly ...

Shanghai Weihai Marine Technology Co., Ltd. provides various types of photography gimbals. Today, we introduce a dual axis underwater photography gimbals, model:P25 Subsea Pan&Tilt。The horizontal swing and vertical pitch of this gimbal are both ± 135 °; The upper limit of rotational speed is 20deg/sec; The upper limit of torque is 25Nm; the load weight is 20kg; the gimbal comes with a standard equipment mounting bracket, which includes a top mounting bracket and two side expansion brackets. If the space is limited, the expansion brackets on both sides can be left uninstalled.For detailed parameters, please feel free to call for consultation.

K.U.M in Germany develops, designs, and manufactures highly specialized and long-life maritime equipment, such as complete seabed seismometer systems, landers, sediment samplers, nuclear storage systems (including pressure pipes, camera housings, shutter buttons, drives, hooks, rotating frames, etc.), and can also modify the equipment to meet customer requirements.Acoustic release device is also one of KUM's main products. KUMQuat (Quality Control Acoustic Trigger/Converter) is a type of acoustic trigger device that is typically embedded in equipment carriers, OBS systems, or complete brackets. It is made entirely of titanium alloy and is suitable for deep-sea operations up to 6000 meters and deeper.The triggering load of the light load trigger is 250kg (higher can be selected), and the triggering load of the heavy load trigger is 500kg (higher can be selected). Bo...

The German KUM brand sediment trap is used to study vertical particle flow in water columns. It is anchored at a specific depth during operation and collects sediment through a funnel, which is then placed in a sample bottle. The materials collected in this way can be used for qualitative and quantitative analysis of biological, chemical, and mineral composition.The German KUM brand sediment capture equipment has multiple advantages and features:1. The German KUM sediment trap adopts a hexagonal frame and can combine multiple samplers.2. There is no oil filled drive.3. The inclination angle of the funnel is 34 degrees, which is more in line with science.4. Adopting a higher honeycomb grid to prevent sediment traps from rotating or being washed away by seawater.……More importantly, the German KUM sediment trap comes with a Chinese version of the acco...

Marine particulate matter records a lot of information about biological activities, physical and chemical processes during its formation, transformation, and deposition. Therefore, it is of great significance for the study of particulate matter flux, marine sedimentology, global change research, and marine environmental monitoring research. Early sediment capture devices could only sample settling particles within a single time period. To obtain samples with temporal resolution, multiple releases were required, which was time-consuming and labor-intensive. The time series sediment trap is a sampling device that sinks to a certain depth in water and automatically collects sediment particles according to a pre-set working program. The collected samples have both accurate time and quantity, as well as high time resolution, making it an important means of collecting marine sediment par...

Courtesy of Chinese Academy of Sciences Core ReadingOn November 28th, the "Striver" completed its 10000 meter deep-sea trial mission and returned smoothly. Since its launch, the "Striver" has completed 13 dives in the Mariana Trench, with 8 of them breaking 10000 meters and setting a new record for manned deep-sea diving in China at 10909 meters... Behind the constantly breaking numbers are technological breakthroughs in key areas such as pressure resistance, control, communication, and buoyancy, reflecting the breakthrough and progress of China's independent research and development of deep-sea equipment technology.On November 28th, the "Striver" deep-sea manned submersible successfully completed its 10000 meter ...
