Abstract
The utility model provides a marine plankton conical multi-screen united sampling device which comprises inverted conical filtering screens, sample collection tubes and a quadrihedron-shaped support, wherein the sample collection tubes are fixed at the bottoms of the filtering screens, and the filtering screens are hung at three corners at the bottom of the quadrihedron-shaped support. According to the marine plankton conical multi-screen united sampling device, the three filtering screens are hung at the three corners at the bottom of the quadrihedron-shaped support and sample marine plankton simultaneously in a united mode, the sampling efficiency is greatly improved compared with the single screen, and the using cost is low. Furthermore, the filtering screens fixed on the support can be collected and released by controlling a rope, so that the operation is simple. In addition, the sampling device is simple in structure and low in manufacture cost.
Description
Technical field
The utility model relates to a kind of for the marine organisms sampling apparatus, and particularly the connection device for picking is netted in a kind of halomereid taper more.
Background technology
Complicated natural phenomena, occurring in the resource that is richly stored with in ocean, and these natural phenomenas are producing tremendous influence to transition, weather, ecologic biological, society & culture, economic development and even the military installations on seashore island again.Only have and accurately, reliable system obtain Ocean Investigation Data; could go deep into cognitive immense ocean; thereby marine environmental protection is made to science, estimating exactly, is data and the information foundation that marine economy development, ocean exploitation, marine disaster prevention and reduction, maritime rights and interests are safeguarded, marine sustainable development provides science.
Plankton general reference moves in water and lacks the drifting organism of effective locomotivity, wherein divides phytoplankton and zooplankton are arranged.Phytoplankton is the main primary producer of ocean, is the basis of aquatic productivity; The output of phytoplankton is determining the output of phytophagy zooplankton, and the latter is determining the output of small fishes and the output of large-scale fish.In addition, plankton also has very important ecological significance and indicative function.At present, it is the important means of oceanographic survey that plankton net is adopted, but traditional net is adopted and existed the unitary sampling time long, the shortcoming that sampling efficiency is not high.In order to address this problem, there is afterwards human hair to understand the Marine Planktonic sampler, the Marine Planktonic sampler has the characteristics of advanced technology, but due to complex operation, expensive, it can not be widely used in oceanographic survey.
The utility model content
The purpose of this utility model is to overcome above-mentioned shortcoming, provides a kind of halomereid taper to net the connection device for picking more, easy and simple to handle, cost is low, sampling efficiency is high.
The technical scheme that realizes the utility model purpose is: the connection device for picking is netted in a kind of halomereid taper more, comprise back taper filter screen and sample collection pipe, wherein, the sample collection pipe is fixed on the bottom of filter screen, it is characterized in that, also comprise the triconic support, three bights of triconic frame bottom have mounted respectively filter screen.Three filter screens are mounted on three angles of triconic support Collect jointly halomereid simultaneously, make the efficiency of its collection high and be independent of each other, and relatively single its use cost of net sampling is lower.Simultaneously, the utility model filter screen adopts the pyramidal structure design, and quality is little, and weight capacity is strong.
The conical top of above-mentioned triconic support is fixed with the main hoisting ring, on the main hoisting ring, is the rope for traction that is useful on retractable bracket.Convenient by the pulley on ship, control rope folding and unfolding filter screen just can, simple to operate.
Three bights of above-mentioned triconic frame bottom are equipped with the net ring, and the third-class office of upper surrounding edge of each filter screen is all that lanyard is arranged, and three lanyards converge and fixedly lie in a net ring; Facilitate filter screen dragging in sampling process, the handling filter screen is convenient and swift.
Above-mentioned support is the triconic that tubing is welded, and guarantees can not occur the phenomenon of disconnected cable when sea situation is poor.
The bottom of above-mentioned filter screen also is fixed with the pendant piece, for ship, starts when filter screen gathers and is convenient to trawlnet.
The length of above-mentioned sample collection pipe is 125cm～135cm, and sample is received in the collection that is applicable to wider scope.
The beneficial effects of the utility model are: adopt three filter screens to be mounted on three angles of triconic support Collect jointly halomereid simultaneously, the relatively single net of collecting efficiency improves greatly, and its use cost is lower, simultaneously, the filter screen that this sampling apparatus only is fixed on support by the folding and unfolding of control rope is just passable, simple to operate, in addition, this sampling apparatus is simple in structure, cost is low.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
In figure, support 1, filter screen mouth 2, filter screen 3, sample collection pipe 4, plummet 5, main hoisting ring 6, net ring 7, rope for traction 8.
Embodiment
Below in conjunction with accompanying drawing, with embodiment, the utility model is described in further detail.
As shown in Figure 1, the utility model provides the connection device for picking of a kind of halomereid, comprises triconic support 1, back taper filter screen 3 and sample collection pipe 4, wherein, sample collection pipe 4 is fixed on the bottom of filter screen 3, and the length of sample collection pipe 4 is generally 125cm～135cm.The bottom of filter screen 3 also is fixed with plummet 5, and three bights of triconic support 1 bottom have mounted respectively filter screen 3, and triconic support 1 can be welded with tubing, to increase its intensity; The conical top of triconic support 1 is fixed with main hoisting ring 6, on main hoisting ring 6, is the rope for traction 8 that is useful on retractable bracket, and rope can be hung on the Cantilever pulley of installing on ship, conveniently slings and puts down the utility model sampling apparatus.Three bights of triconic support 1 bottom are equipped with net ring 7, and the third-class office of upper surrounding edge of each filter screen 3 is all that lanyard is arranged, and three lanyards converge and fixedly lie in a net ring 7.Usually, plankton collector quality is larger, the phenomenon that disconnected cable is lost instrument can occur when sea situation is poor, and the utility model adopts the pyramidal structure design, and resistance is little, and quality is little, and weight capacity is strong, can evade the phenomenon of disconnected cable
As shown in Figure 1,2 is the filter screen mouth, and halomereid enters filter screen 3 by filter screen mouth 2, then is filled into sample collection pipe 4 by filter screen 3.Plankton haul usually comprises phytoplankton trawlnet, zooplankton, fish eggs and larvae etc.Single net sampling is consuming time more, uses the utility model can carry out three net connection simultaneously and adopts.Take and gather 3 nets as example, suppose network speed 2m/s, rinse and the 3 minutes time of falling the sample, during sampling depth of water 500m, use this device can save 10-20 minute, during sampling 200m, use this device can save 8-12 minute.If 40 erect-positions of flight number design, can save ship time half a day left and right, save a large amount of funds, therefore, use cost of the present utility model is low.
Above-described embodiment is only preferred embodiment of the present utility model, not is used for limiting practical range of the present utility model.Be that all equalizations of doing according to the utility model content change and modify, all contained by the utility model claim scope required for protection.
