According to the utility model, the related composite cable for collecting the seawater sample realizes collection and whole-process closed conveying of the seawater sample in the specified depth, can keep physical, chemical and biological properties of the seawater sample to the greatest extent, has the advantages of large seawater collection amount, high simplicity and easiness in use and the like, and plays an important role in improving the seawater sampling efficiency.
Description
Technical field
The utility model relates to the marine environmental monitoring device, particularly relates to a kind of seawater sample and gathers composite rope.
Background technology
Developing rapidly of marine economy brought day by day serious environmental problem, particularly nearshore marine environment to bear huge pollution pressure, and marine environmental monitoring is further paid attention to as the element task of marine environmental protection.
The ocean water quality detection is the important component part of marine environmental monitoring, measures the seawater quality parameter, analyzes water quality environment situation or pollution level, for marine environmental protection and scientific research of seas provide basic data.A kind of important means of ocean water quality detection is to utilize water sampling equipment that seawater is collected on ship, and then brings back in laboratory and analyze.
General water sampling method is that the seawater that utilizes water pipe will draw different water layers with water pump is drawn onto on ship.Suction hose is adopted water by tying up the hawser applied together under the Action of Gravity Field that hangs fish lead, entering water, judges the degree of depth of institute's water sampling according to the scale of indicating on water pipe.But water pipe can produce under the effect of current, this method can not accurately obtain the degree of depth of institute's water sampling.
Summary of the invention
For the existing problem of existing water sampling method, the utility model is released a kind of novel seawater sample and is gathered composite rope, centralized procurement water, load-bearing and signal are transmitted in one, suction hose, signal cable, head-rope are combined, signal cable connects the pressure transducer of suction hose end, to realize accurately gathering the seawater sample of different depth aboard ship.
The seawater sample that the utility model relates to gathers composite rope and is combined side by side by suction hose, signal cable and head-rope, outer wrap polyurethane crust.Gather the lower end of composite rope at seawater sample, the water pipe water inlet of suction hose end arranges pressure transducer, and water pipe water inlet and pressure transducer are in the same level position, and pressure transducer connects the end of signal cable, and the head-rope end hangs fish lead.Gather the upper end of composite rope at seawater sample, suction hose connects water pump, and signal cable connects display.
Signal cable is by four cross section 0.3mm
2copper conductor and insulation course form, signal cable is through the signal cable sleeve pipe of hollow, the external diameter of signal cable is less than the internal diameter of signal cable sleeve pipe.Signal cable can be loosening in signal cable sleeve pipe the inside, reduces the stressed of thinner signal cable, in order to avoid because of stressed interruption.Simultaneously, four middle spaces of copper conductor arrange Kev and draw gasket for packing, so that cable can bear certain pulling force.
When the seawater sample that the utility model relates to gathers the composite rope application, the gravity that hangs fish lead by head-rope sinks to marine by the lower end of composite rope, water pump on the other end connected boat of suction hose, water pump is drawn water sample from the water pipe water inlet of putting into seawater, completes the collection of water sample.One end of signal cable connects the pressure transducer of water sucking mouth, and sensor is exported the current signal be directly proportional to water depth pressure, determines the sampling depth of water sample by the size of calculated current signal.Due to the pressure transducer collection be the pressure at right angle of seawater, irrelevant at marine angle of inclination with composite rope, so can accurately determine the sampling depth of water sample.
The seawater sample that the utility model relates to gathers composite rope and has realized collection and the omnidistance sealing of designated depth seawater sample are carried, the Physical and chemical and biological property that can keep to greatest extent seawater sample, have the water yield of adopting large, the advantage such as be simple and easy to use, to improving the seawater sampling efficiency, play an important role.

Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described.Fig. 1 shows the cross section basic structure of the seawater sample sampling composite rope that the utility model relates to, and Fig. 2 shows the application feature of seawater sample sampling composite rope.
As shown in the figure, the seawater sample that the utility model relates to gathers composite rope 10 and is combined side by side by suction hose 1, signal cable 4 and head-rope 5, outer wrap polyurethane crust 2.Signal cable 4 is by four cross section 0.3mm
2copper conductor and insulation course form, signal cable 4 is through the signal cable sleeve pipe 3 of hollow, the external diameter of signal cable 4 is less than the internal diameter of signal cable sleeve pipe 3, the spaces in the middle of four copper conductors arrange Kev and draw gasket for packing.
Water pipe water inlet 6 places of suction hose 1 end arrange pressure transducer 8, and pressure transducer 8 connects the end of signal cable 4, and head-rope 5 ends hang fish lead 7.The lower end that seawater sample gathers composite rope 10 installs containment vessel 9 additional; the critical components such as protection water pipe water inlet 6 and pressure transducer 8; the pressure perception hole of water pipe water inlet 6 and pressure transducer 8 is exposed at the outside of containment vessel 9, and water pipe water inlet 6 and pressure transducer 8 are in the same level position.Gather the upper end of composite rope 10 at seawater sample, the water pump that suction hose 1 connects on monitoring ship 11, the display that signal cable 8 connects on monitoring ship 11.
When the seawater sample that the utility model relates to gathers composite rope 10 collection in worksite seawater sample, the gravity that hangs fish lead 7 by head-rope 5 will gather the lower end of composite rope 10 and sink to marine, after the set depth that arrives display, open water pump, can carry out the collecting work of seawater sample.Water pump on monitoring ship 11 is drawn and is gathered water sample from the water pipe water inlet 6 of putting into seawater.After the seawater sample collection completes, seawater sample is gathered to composite rope 10 and be recovered on monitoring ship 11 together with sampling head.
