Description

A kind of table shallow-layer sludge sampler

Technical field

The present invention relates to a kind of sampler for the collection of bilge mud sample.

Background technology

With flourishing for global economic integration and shipping industry, on the one hand it is greatly promoted international trade and increases rapidly It is long, on the other hand, continually to be travelled to and fro between due to International Voyage Ship all over the world, the seawater in ballast tank of ship is in regional Exchange, also for the intrusion of alien species and the propagation of infectious disease provide faster, more convenient condition, to human health structure Into potential threat.

International shipping water ballast during navigation is constantly exchanged with the external world, some mud for bringing therewith and various aquatic Biological, microorganism gradually deposits, resides in the bottom of ballast tank.Mud have many aquatiles and microorganism life needed for The good base that various conditions are aquatile and growth of microorganism, perch, breed.It is various biological in silt compared with water ballast Living environment in mud is relatively more stablized.Therefore, if causal organism is survived in the mud of ballast tank bottom, these have Harmful is biological in constantly being bred from mud during international shipping is navigated by water and being diffused into water ballast, with the exchange of water ballast And send out.Mud is not as water ballast and equally often changes, but is discharged into difference in shiprepair or desilting after certain hour Place, the discharge of mud is likely to entrained pathogenic microorganism can be sent out into new region, threatens surrounding enviroment and the mankind strong Health.

Health quarantine department liable in frontier port is given birth to international shipping ballast tank discharged ballast water and bottom sludge Thing harm monitoring, for the collection of ballast tank bottom sludge sample, more using instruments such as negative pressure tubular type bottom samplers, bilge mud tool There is viscosity to differ, the features such as mud layer is thin, instrument access times be inconvenient to safeguard after increasing, it is necessary to develop it is easy to use, facilitate The instrument of maintaining.

The content of the invention

Regarding to the issue above, the invention provides a kind of table shallow-layer sludge sampler, simple structure is reasonable in design, uses Easy, carrying is easy to maintenance, is conducive to live quarantine functionary to carry out mud sampling.Technical scheme specific as follows is as follows.

The application provides a kind of table shallow-layer sludge sampler, and the sampler includes handle, sampling cylinder, handle, connecting rod, three Angle-style support, spring, universal driving shaft, rotary shaft and base plate, the handle are located at the outside of sampling cylinder, and its two ends is fixed on sampling cylinder Lateral wall, handle is fixed on handle, and the triangular form support is fixed on the top of sampling cylinder, and the connecting rod passes through triangular form The interstitial hole of support and its top be fixed on handle；The upper end of the spring is fixed on triangular form support, the lower end of spring It is fixed on connecting rod；Connecting rod lower end is connected with universal driving shaft；The bottom of sampler is sealed by base plate, and the side of cutting of base plate passes through to turn Moving axis is connected, and rotary shaft is fixed on the bottom inside wall of sampling cylinder, and the base plate top is solid respectively with two end points of universal driving shaft Fixed connection.

Preferably, the base plate is shaped as semicircle, two pieces.

Preferably, the rotary shaft is two.

Preferably, the base plate can be along the tie point of sampling cylinder bottom and the rotary shaft to doing 90 degree of rotations in cylinder.

Preferably, each part of the sampler is bolted.

Preferably, the handle side is provided with groove, can be slided up and down along handle in handle two ends insertion groove.

When using, the handle of sampler is lifted, handle drives the universal driving shaft of sampler bottom by connecting rod, by sampler Bottom base panel is opened, and after insertion certain depth, unclamps handle, and connecting rod promotes universal driving shaft by bottom under the elastic force effect of spring Base plate closes up, while bottom sampler is lifted from mud, the gravity of content can also aid in closing up base plate, closed bottom, from And conveniently propose.Go at container, handle is lifted up, the mud in sampling tank discharges sampler by self gravitation.Adopt Sample device can facilitate dismounting to carry out disinfection treatment.

Beneficial effect：The sampler that the present invention is provided, simple structure is reasonable in design, and easy to use, carrying is easy to maintenance, Being conducive to live quarantine functionary carries out mud sampling.

Specific embodiment

Come that the present invention is described in detail below in conjunction with the accompanying drawings.

As Figure 1-5, the sampler that the present invention is provided includes handle 1, sampling cylinder 2, handle 3, connecting rod 5, triangular form branch Frame 9, spring 4, universal driving shaft 6, rotary shaft 7 and base plate 8, handle 1 are located at the outside of sampling cylinder 2, and its two ends is fixed on sampling cylinder 2 Lateral wall, handle 3 is fixed on the middle part of handle 1, and the top of connecting rod 5 is fixed on handle middle part, and triangular form support 9 is fixed on sampling cylinder Interior top, the upper end of spring 4 is fixed on triangular form support, and the lower end of spring is fixed on connecting rod middle part, and connecting rod 5 can freely be worn The interstitial hole for crossing triangular form support 9 is connected with handle 3, and connecting rod lower end is connected with the middle part of universal driving shaft 6, and the bottom of sampler passes through Base plate 8 is sealed, and base plate is divided into two semicircle base plates, and the side of cutting of two semicircle base plates is connected by rotary shaft 7, rotary shaft It is fixed on the bottom inside wall of sampling cylinder.Two semicircle base plate tops are respectively fixedly connected with two end points of universal driving shaft, even By axle of rotary shaft can be folded up two semicircle base plates by lifting universal driving shaft by bar.

Specifically, the present invention needs to lift the handle 3 of sampler when in use, as shown in figure 5, handle 3 passes through connecting rod 5 Drive the universal driving shaft 6 of sampler bottom to open sampler bottom base panel 8 by rotary shaft 7, i.e., made by the effect of rotary shaft Simultaneously to being rotated by 90 ° in sampling cylinder to base plate and sampling cylinder plane perpendicular, now, firmly pin the upper end of handle 1 makes two pieces of base plates After the insertion certain depth of sampler base plate 8, handle 3 is unclamped, connecting rod 5 drives universal driving shaft 6 to pass through under the elastic force effect of spring 4 Rotary shaft 7 closes up bottom base panel 8, while sampler is lifted from mud, the gravity of content can also aid in closing base plate 8 Hold together, closed bottom, so that convenient propose.Go at container, handle 3 is lifted up, the mud in sampling tank is by itself weight Power discharges sampler.Sampler can facilitate dismounting to carry out disinfection treatment.

The above, the only present invention preferably specific embodiment, but protection scope of the present invention is not limited thereto, Any one skilled in the art in the technical scope of present disclosure, technology according to the present invention scheme and its Inventive concept is subject to equivalent or change, should all be included within the scope of the present invention.
