A kind of water quality table environment shooting, collecting intelligence equipment parallel manipulator
Technical field
The present invention relates to waters field of work machines, a kind of water quality table environment shooting, collecting intelligence equipment is used
Parallel manipulator.
Background technology
Water environment refers to the formation of water in nature, is distributed and converts the environment in residing space, refers to around people's group space
And can directly or indirectly affect the water body of human lives and development, the various natural causes of its normal function and relevant society because of
Plain is overall;Also referring to of having is metastable, the environment in space residing for natural water area with land as border, at the earth's surface,
Coverage of water accounts for 71% that earth surface is long-pending, and water is made up of, respectively with total Water ocean water and terrestrial water two part
97.28% and 2.72%.Shared by the latter, sum-rate is the least, and the environment in residing space is sufficiently complex.Water environment is mainly by ground
Table water environment and groundwater environment two parts composition, surface water environment includes river, lake, reservoir, ocean, pond, marsh, ice
River etc., groundwater environment includes spring water, phreatic water, deep phreatic water etc., water environment be composing environment fundamental it
One, it is the important place depended on for existence and development of human society, is also by Human impact and to destroy the most serious field.
Water is the affluent resources that people depend on for existence, and people utilize water environment can carry out multiple affairs, such as fishery water
Produce cultivation, water transportation waterborne, water resource generating etc., progressively increasing water resource utilized along with people, therewith waterborne
Operation also gets more and more, and such as aquatic environment monitoring observation, water surface traffic cruise, waters shooting passback, water-quality observation, waterborne searches
Helping and help etc., the one side all be unableing to do without for above work at present shoots operation exactly, first to water environment table body
Carrying out data and picture analysis after carrying out photo acquisition, finding out useful information, at present mostly people is for shooting operation waterborne
Work is gone by ship handheld camera shooting, but manually there is person risk in waters operation, also has and carries out unmanned plane on a small quantity and take photo by plane, but
Unmanned plane due to continuation of the journey problem can not large area long working, therefore suffer from limiting accordingly;In addition, present shooting
Operation many employings spider, but regulation orientation angles is limited, and very flexible when regulating, it is poor to stablize, when causing shooting by
Fluctuation in motion carrier causes shooting picture jitter big, the quality of impact shooting.In view of the above circumstances, the invention provides
