The invention discloses a collector for sea water on the surface of a polar region. The collector comprises a water pumping device, a filter device and a fixed device, wherein the water outlet end of the water pumping device is connected with the filter device; the fixed device is arranged below the filter device; the water pumping device comprises a gear pump, a throttle valve, a pressure gauge, a fixed guide tube support, a water inlet, a water outlet guide tube and a flaring; the filter device comprises a primary filter unit, a secondary filter unit, a residue drain port and an outer housing; a through hole is formed in the middle of the upper end of the outer housing; the water outlet guide tube penetrates through the through hole; the primary filter unit is arranged just under the flaring; the secondary filter unit is arranged just under the primary filter unit; the lower end of the outer housing is connected with the residue drain port; the fixed device comprises supporting seats and screws; one ends of the supporting seats are fixedly connected with the outer housing, and the other ends of the supporting seats are connected with the screws. The collector is used for removing ice particles in collected sea water during scientific expeditions in the Antarctic and the Arctic, so that real and accurate original data of the collected sea water can be ensured. The collector is simple in structure and low in manufacturing cost.

A giant gully-crossing vehicle for polar scientific expeditions, including a gully-crossing bridge and a vehicle body. The vehicle body includes a stage and a travelling portion. The stage includes a top platform, a front bottom plate, a rear bottom plate and a multifunctional lock platform assembly. The front bottom plate and the rear bottom plate are capable of sliding independently relative to the top platform. The travelling portion includes a first travelling component, a second travelling component, a third travelling component, a fourth travelling component, a fifth travelling component and a sixth travelling component which are symmetrically provided at left and right sides of the stage and below the stage. Bridge bodies of the bridge components can be assembled to two gully-crossing bridges, and are connected to the multifunctional lock platform assembly when crossing gullies.

The invention discloses a scientific research ship with an rolling stabilizing water compartment system. The scientific research ship is provided with a hull and a cabin, the cabin is internally provided with an rolling stabilizing water compartment system, the rolling stabilizing water compartment system comprises a water compartment body which is composed of a left compartment, a right compartment and a connecting compartment which is communicated with the left and right compartment, the water compartment body is internally filled with liquid and comprises left and right adjusting compartments which are arranged in the left and right compartments respectively, a baffle which penetrates through the connecting compartment to divide the connecting compartment into a lower connecting compartment and an upper connecting compartment is arranged on the part between the left and right adjusting compartments, left and right rapid adjusting compartments are formed in the parts between the leftand right adjusting compartments and the outer side walls of the left and right compartments respectively, and rapid adjusting devices and air pressure adjusting devices which are used for controlling the heights of liquid levels of liquid in left and right passive compartments are arranged in the left and right adjusting compartments respectively. The rolling stabilizing water compartment systemhas the advantages that the rolling stabilizing water compartment system can effectively operate within a wider frequency range, and rolling increasing does not take place both in low and high frequency ranges.

The invention aims at the safety arrangement requirement of the existing gliding turbulence profiler, the invention relates to a gliding turbulence profiler distribution device and an operation methodthereof, the device is fixed on the operation deck of a scientific research ship, A hydraulic pump station is used to drive the hydraulic cylinder and the motor to provide power, the gliding turbulence profiler is transported from the operation deck to the sea surface by a rotary mechanical boom, then switch on the electromagnetic switch of the glide track between the glide turbulence profiler and the boom, Front end limit of boom, a mooring electromagnetic switch between the gliding turbulence profiler and the floating mooring drum, The invention solves the technical problem that the glidingturbulence profiler developed in China does not develop a special distribution device at present, and the known distribution scheme is extremely easy to cause the collision damage of the gliding turbulence profiler to be inoperable, and the gliding turbulence profiler starts to glide according to a predetermined route. The invention greatly improves the reliability and safety of the gliding turbulence profiler deployment, and provides a powerful guarantee for obtaining marine survey data.
