Scientific research vessel environment instrument release auxiliary device and working method thereof

Abstract

The invention relates to a scientific research vessel environment instrument release auxiliary device. Equally-divided angle portions on the upper portion of a ring are connected with the lower ends of multiple straight steel columns, the upper ends of the straight steel columns are connected with a rotary disc, and the upper end of the rotary disc is connected with a lifting ring; six lower hanging components are arranged on the 60-degree equally-divided portions on the lower portion of the ring, a pair of connecting rods penetrating through the center of a circle are further fixedly arrangedon the ring, and a seventh lower hanging component is arranged in the crossed position of the pair of the connecting rods; when needing to be hung, one suspension object is hung on the lower hangingcomponent in the center portion; when needing to be hung, two suspension objects are hung on the pair of the lower hanging components 180 degrees away from each other; when needing to be hung, three suspension objects are hung on the three lower hanging components 120 degrees away from each other; when needing to be hung, four suspension objects are hung on the fourth lower hanging components symmetric about the ring bisector as the central axis; the four suspension objects are provided with balancing weights, so that the weights of the multiple suspension objects are equal; and according to the actual specific requirements, 5 to 7 suspension objects can be hung as well, and the balance of the whole device can be kept.

Description

technical field [0001] The invention relates to an auxiliary equipment of a scientific investigation ship, in particular to an auxiliary device for launching environmental instruments of a scientific investigation ship. Background technique [0002] When investigating marine fishery resources, the collection of data on marine plankton and physical and chemical environmental factors is especially important for assessing fish migration and other activities. Plankton includes zooplankton and phytoplankton, which are generally collected vertically on the seabed through zooplankton nets and phytoplankton nets; physical and chemical environmental factors are mainly collected by vertically placing them on the seabed through CTD and water collectors, and CTD can directly collect temperature and salinity , dissolved oxygen and chlorophyll, etc., the water samples collected by the water collector can be used to analyze the chemical characteristics such as the inorganic salt content of...

Problems solved by technology

On the one hand, this survey method prolongs the survey time. If there is bad weather such as typhoon or cold air, the expected survey task cannot be completed; on the other hand, a large amount of fuel costs will be wasted due to the extended operation time.
