Abstract
The invention discloses a frame type three-parameter marine environment vertical survey device, which relates to a marine environment investigation tool. According to the technical scheme provided by the invention, a zooplankton vertical drag net, a phytoplankton vertical drag net and marine physical special survey equipment are adopted; the device is characterized in that a frame with length of 2 m and width of 0.8 m which is made of circular steel pipes is arranged, wherein the inner sides of the two ends of the frame are welded into square frames with side lengths of 800 mm and 370 mm respectively; a bracket with a U-shaped ring is connected in the middle of the two square frames; the square frames at the two ends are used for fixedly mounting the zooplankton vertical drag net and the phytoplankton vertical drag net respectively; the U-shaped ring suspension marine physical special survey equipment is arranged in the middle of the bracket close to the phytoplankton vertical drag net; four cross ropes are tied to the corners of the frame; the four cross roes are used for keeping balance of the survey device in the survey process; and the upper ends of the four cross ropes are connected with one drag rope for controlling the survey operation depth.
Description
Technical field
The present invention relates to the marine environment investigation instrument.
Background technology
Present marine environment investigation mainly comprises the investigation of marine organisms and marine physics, and marine organisms investigation net drags by 1 the vertical investigation trawlnet that guiding principle, 3 fork guiding principles, 1 network interface ring, 1 body, 1 net bottom pipe and weight form.The living marine resources investigation can be divided into macroplankton net and microplankton net according to the difference of sampling object, the structure of two kinds of net types also has larger difference, in actual sampling process, often different because of the requirement of sampling object at same sampling spot, two kinds of netting gears need be taken a sample respectively.the marine physics investigation is main by special equipment (temperature, salt, deep profile instrument or Multifunctional water instrument) complete, Investigation requirements is the same with biological vertical investigation net, carry out in the vertical direction data acquisition, as sample mode routinely, carry out vertical trawlnet and the marine organisms parameter acquisition of the 200m depth of water, each sample point need carry out 3 vertical samplings investigation, approximately need spend the sample time of 180 minutes, due to boats and ships wind-engaging during the process of the investigation, the impact of the external environments such as stream easily produces boats and ships and drifts about, particularly the position of 3 sub-samplings is difficult to be consistent in strong wind atmosphere, the error that easily causes sampling result to analyze.
Summary of the invention
What the present invention need to solve is that marine organisms sampling net and the marine physics special surveying equipment organic assembling of two kinds of different sampling objects are integral.
Technical scheme of the present invention adopts the vertical trawlnet of zooplankton, the vertical trawlnet of phytoplankton and marine physics special surveying equipment, it is characterized in that setting 2 meters of length made from round steel pipe, the framework of wide 0.8 meter, and the inboard at framework two ends is welded into respectively the square frame of length of side 800mm and length of side 370mm, connect the support with U-shaped ring in the middle of two square frames; The square frame at two ends is respectively used to fixedly mount the vertical trawlnet of zooplankton trawlnet vertical with phytoplankton, and being positioned in the middle of support the partially near vertical trawlnet net of phytoplankton side, to be provided with U-shaped ring outstanding be marine physics special surveying equipment; There are 4 fork guiding principles in the corner of framework system, keeps the balance of investigation apparatus in fact-finding process with 4 fork guiding principles, and 4 fork guiding principle upper ends connect one and drag guiding principle and be used for controlling and investigate depth of implements.
the present invention is because the network interface with living marine resources investigation net is transformed into frame structure, the vertical trawlnet of plankton of two kinds of different sizes is installed respectively in inboard, framework two ends, marine physics special surveying equipment is installed on frame mid portion and is partial to less biological vertical trawlnet one side, the vertical trawlnet of plankton and marine physics special surveying equipment form the integral type investigation apparatus, two kinds of vertical trawlnets of specification plankton and marine physics special surveying equipment are combined, vertical traw mouth and marine physics special surveying equipment are maintained at the same horizontal plane, its advantage is to make original 1 investigation website need the investigation of 3 vertical operations only need just can complete for 1 time, control time can reduce to 50-60 minute from original 150-180 minute, significantly improved the efficient of marine environment investigation.Simultaneously, the present invention makes simply, easy to operate, the uniformity that keeps the vertical trawlnet of zooplankton, the vertical trawlnet sampling of phytoplankton and marine physics special surveying device location, owing to the vertical trawlnet of zooplankton, the vertical trawlnet of phytoplankton position possessing a determining deviation, the water body of not only can avoiding gushing out in different vertical trawlnet net in fact-finding process enters the interior impact on investigation result of adjacent net, also can analyse and investigate more exactly the plankton stock number of position and the correlation of marine environment, be the vertical researching tool of a kind of efficient marine environment.

Embodiment
The present invention's (referring to accompanying drawing) adopts the vertical trawlnet 3 of zooplankton, the vertical trawlnet 4 of phytoplankton and marine physics special surveying equipment 5; The present invention sets 2 meters of length made from round steel pipe, the framework 1 of wide 0.8 meter, the diameter of round steel pipe is the most suitable with 50mm or 50mm left and right, and the inboard at framework two ends is welded into respectively the square frame of length of side 800mm and length of side 370mm, connects the support with U-shaped ring 2 in the middle of two square frames; Inboard square frame size according to two ends, the square frame at two ends is respectively used to fixedly mount the vertical trawlnet of zooplankton trawlnet vertical with phytoplankton, the using method of the vertical trawlnet of zooplankton and the vertical trawlnet of phytoplankton is identical with the vertical trawlnet that it independently uses, but the present invention has reduced 3 fork guiding principles of investigation netting gear balance; It is marine physics special surveying equipment that the U-shaped ring that is positioned at the middle partially near vertical trawlnet side of phytoplankton of support is used for hanging; There are 4 fork guiding principles 6 in the corner of framework system, keeps the balance of investigation apparatus in fact-finding process with 4 fork guiding principles, and 4 fork guiding principle upper ends connect one and drag guiding principle 7 and be used for controlling and investigate depth of implements.
Use fact-finding process of the present invention identical with the requirement of marine physics special surveying equipment operating with the vertical trawlnet of single plankton, risen by special-purpose winch and put operation.In the vertical trawlnet of zooplankton trawlnet decline vertical with phytoplankton process, keep netting the position vertically by 8 tractions of bottom weight.Marine physics special surveying equipment need not installed weight, synchronously descends with the vertical trawlnet of zooplankton trawlnet vertical with phytoplankton.In sampling process, except need carry out the preservation of marine physics special equipment operation setting and data counts at every turn, need simultaneously the sampling result of trawlnet vertical according to zooplankton and the vertical trawlnet of phytoplankton to make a record respectively, in order to avoid mutually obscure.
