Description
Technical field
The utility model relates to a kind of river phytoplankton harvester, is used for the collection of small-sized phytoplankton.
Background technology
At present, known phytoplankton sampling thief is an III type plankton net, is coniform, is mainly used in to gather the phytoplankton sample, and its structure network interface, etting and net bottom sampling jar connect and compose.Network interface is made by metal edge frame, and is generally rounded, is used for support and fixing to etting, simultaneously fixed pulling rope; Etting is made by the certain bolting silk in aperture; The net bottom sampling jar is connected the etting end, in order to the planktonic organism sample in the collecting net.During use, earlier certain fish lead is fixed on III type planktonic organism sieve bottom, slowly be discharged in the water, go out the water surface to the certain depth post-tensioning, water cleans etting is collected in the net bottom sampling jar sample, open the sampling jar valve at last, the water in the sampling jar is transferred in the sample bottle together labelled getting final product with sample.This method was used nearly 40 years in China, did not do any improvement always, had following defective:
1. the plankton net volume is big, weight is bigger, adopts the manpower sampling, operation inconvenience and effort.
2. the error of calculation of drainage amount is bigger.In the river, sample, be subjected to water currents can not keep vertical sample states, be difficult for determining sampling depth, under the situation in sampling angle and sampling time, estimate the drainage amount and exist, and the phytoplankton biological density and the actual conditions that calculate with this drainage amount are not inconsistent than mistake.
Summary of the invention
The purpose of this utility model provides a kind of river phytoplankton harvester, to overcome the deficiencies in the prior art.
A kind of river phytoplankton harvester, comprise the bracing frame that has the pulley support bar, it is characterized in that also comprising the suction pump that has drinking-water pipe that is fixed on the bracing frame, one end of this drinking-water pipe is connected with movable flexible pipe, the other end of movable flexible pipe is connected with the sampling head of bottom band screen pack, described sampling head via the steel cable of walking around pulley by the reel folding and unfolding; The other end of above-mentioned drinking-water pipe feeds the receiving flask that the bottom has valve via bolting silk.
Above-mentioned sampling head is stainless funnel-shaped structure.
Above-mentioned screen pack is that the aperture that the 1mm iron wire is made is the entanglement of 5mm.
Above-mentioned movable flexible pipe is a plastic flexible pipe.
Above-mentioned suction pump is flow 30m
3/ h provides the suction pump of power by ship.
Above-mentioned sample collection bottle is a steel cylinder.
Above-mentioned bracing frame is fixed with suction pump and reel with handles, and has the pulley support bar for fixing metal framework structure aboard ship on the bracing frame.
Utilize sampling principle of the present utility model as follows: at first to regulate sampling head to desired depth, the locking steel cable by the steel cable of band scale; Open suction pump then, current enter water pipe by tubaeform sampling head, and large-scale suspension is because of being entered drinking-water pipe every the interception of foreign material net; Planktonic organism enters in the bolting silk net with current, and ecto-entad flushing bolting silk entered the planktonic organism flushing in the net bottom sampling jar after sampling finished.The volume of water sampling can be tried to achieve by the flow velocity and the sampling time of suction pump.
The utility model couples together water sampling device and filtering biological sampling thief guaranteeing to have on the function basis of III type plankton net, and adopts propulsion system to collect the phytoplankton sample, and it is fast to have sample rate, rapid operation, convenience; Sampling head can move up and down, and can gather the water sample of each desired depths such as top layer, bottom; Drainage amount convenience of calculation is accurate, has improved sampling efficiency and security.
