87 results about "Deep ocean water" patented technology

Deep ocean water (DOW) is the name for cold, salty water found deep below the surface of Earth's oceans. Ocean water differs in temperature and salinity. Warm surface water is generally saltier than the cooler deep or polar waters; in polar regions, the upper layers of ocean water are cold and fresh. Deep ocean water makes up about 90% of the volume of the oceans. Deep ocean water has a very uniform temperature, around 0-3 °C, and a salinity of about 3.5% or as oceanographers state as 35 ppt (parts per thousand).

Deep ocean water pressure-retention sampling device based on controllable one-way valve cascaded structure

The invention provides a deep ocean water pressure-retention sampling device based on a controllable one-way valve cascaded structure, which belongs to the field of an ocean technological instrument. Two controllable one-way valves (an electromagnetic one-way valve and a manual one-way valve) are reversely arranged in a pipeline at the front end of a sampling cylinder in serial connection to realize pollution-free sampling, pressure-retention sampling and sample constant-pressure transferring; the way for additionally arranging a pressure compensation cylinder behind a sample cylinder realizes the continuous and mutation-free compensation to the pressure of a sample cavity; a method for filling a space between a sampling piston and a compensation piston with clean seawater and processing a throttling hole in the center of a connection body, pressure-mutation-free sampling is realized; and a one-way valve assembly and a choke plug are installed on an end cover of the compensation cylinder, so that the reliability of the sampling device is improved. All static connection in the sampling device is sealed by virtue of an O-shaped ring end surface, so that the sealing performance of the sampling device is improved. The deep ocean water pressure-retention sampling device is compact in structure, fewer in accessory equipment, simple in a sampling triggering signal and particularly suitable for being equipped with an AUV (Autonomous Underwater Vehicle) to collect deep ocean water samples.

24-hour moist three-layer moisturizing and repairing system

The invention belongs to the field of cosmetics, and relates to a moisturizing technology in skin care products, namely a 24-hour moist three-layer moisturizing and repairing system. The skin care product provided by the invention is characterized in that kelp extractive, deep ocean water, pansy extractive and a water catching factor form a three-layer moisturizing and repairing system; the kelp extractive contains a plurality of minerals, saccharides and amino acid and has the moisturizing effect of reinforcing surface water locking of skin; the pansy extractive promotes synthesis of aquaporins in cell membranes, improves water circulation of dermis and promotes water to transfer from dermis to cuticle; silicon and manganese elements in the deep ocean water can reduce transepidermal water loss and are cooperative to achieve the effect of activating water deeply; and the water catching factor ensures that skin has the moisturizing effect of catching water outside. By means of the three-layer moisturizing and repairing system including surface water locking, water activating deeply and water catching outside, the skin care product provided by the invention can bring an intelligent lasting moisturizing technology to skin, so that bright, smooth, transparent and moist skin is brought.

Ultra-high pressure sea water pressure balance valve

The invention discloses an ultra-high sea-water pressure balance valve, comprising a valve seat, a valve body and a valve pocket. The valve body is a tee joint. Both the valve seat and the valve pocket are in a tubular shape, the inner ends of the valve seat and the valve pocket are sealed, inserted into and fixed on the two ends sharing the same axial line with the valve body, and a segment inner hole of the inner end of the valve body is a taper hole. A valve flap and a spring are arranged inside the valve body. One end of the valve flap is arranged in the valve body, and the other end is inserted into the valve pocket. A taper head is arranged at one end of the valve flap, and the taper angle of the taper head is equal to the taper angle of the taper hole of the inner end of the valve seat; under non-working state, the taper head of the valve flap is arranged against the taper hole of the inner end of the valve seat. A spring is coated on the valve flap. Under non-working state, the taper head of the valve flap and the taper hole of the inner end of the valve seat closely match with each other by the seal ring. The invention can not only seal the hydraulic oil with relatively big viscosity, but also seal deep-ocean water, and the scope of application is not limited. The invention can be used to adjust the balance of the weight and buoyancy of a deep-ocean robot.
