Fig. 1-5, a kind of closed bilge sampler, including top shell 1 are please referred to, is equipped with cavity components, the bottom of top shell 1 in top shell 1 End is fixedly connected with protective cover 2, and the bottom end of protective cover 2 is fixedly connected with relief valve 7, is equipped with bilge sample bucket 6 in the protective cover 2, The top of bilge sample bucket 6 is fixedly connected with hook 4, and the cavity components include shaft 28, measuring scale 3 and mounting disc 29, turns Axis 28 is fixedly and coaxially connected with mounting disc 29, and mounting disc 29 is equipped with and measuring scale 3, one end of measuring scale 3 and the fixed company of hook 4 It connects, the bottom end of the relief valve 7 is fixedly connected with setting-out valve 8, and the top in the bilge sample bucket 6 and bottom end are respectively equipped with upper valve Upper valve core 19 and bottom spool 26, the top of bilge sample bucket 6 are respectively equipped in seat 15 and lower valve base 16, upper valve base 15 and lower valve base 16 End is equipped with hanging hook assembly 20, and fixing screws 22, the top of hanging hook assembly 20 are fixedly connected between hanging hook assembly 20 and bilge sample bucket 6 End center offers air hole 21, and lower guide rod 18 and top guide bar 33 are coaxially provided in bilge sample bucket 6, and top guide bar 33 runs through upper valve The top of core 19, top guide bar 33 is threadedly coupled locking nut 24, and holddown spring 23 is equipped between upper valve core 19 and hanging hook assembly 20, The bottom end of the lower valve base 16 is equipped with lead channel 27, and lower valve base 16 and the junction of upper valve base 15 are equipped with the first sealing ring 25.

One end of the shaft 28 passes through top shell 1 and is fixedly connected with rotating handle 10, the company of the top shell 1 and protective cover 2 The place of connecing is threaded with rapid abutting joint bolt 12, and the side of the protective cover 2 is fixed with vent valve 5, the relief valve 7 it is outer Portion is equipped with relief valve handle 13, and the bottom end of the protective cover 2 is fixedly connected with quick coupling 14, and the top shell 1 is equipped with form 11, Junction, bottom spool 26 and the junction of lower valve base 16 of the upper valve core 19 and upper valve base 15 are equipped with the second sealing ring 30, The outside of the lower guide rod 18 is fixedly connected with clump weight 17, and the fixed spiral shell of counterweight is threaded between clump weight 17 and lower guide rod 18 The bottom end of silk 31, protective cover 2 connects deck valve.

Embodiment 2

Fig. 1-5 is please referred to, other contents of the present embodiment are same as Example 1, the difference is that: outside the protective cover 2 Side is electrically connected ground line 9.

The present invention connects 14 on deck valve 32 in implementation process, 2 cun of quick couplings of closed cabin bottom sampler, releasing It puts valve handle 13 and turns to and take sample position, rotate rotating handle 10, transfer bilge sample bucket 6 until the bilge, at this moment cabin The upper valve core 19 and bottom spool 26 of bottom sample bucket 6 are opened, and liquid flows into from bottom spool 26, in bilge sample bucket 6 gas from It is excluded at upper valve core 19, static 5 minutes or so, reversed uniform rotation rotating handle 10 put on bilge sample bucket 6 and comes protection In cover, relief valve handle 13 is gone to and unloads sample position, deck valve 32 is closed, setting-out valve 8 is opened, sample container is placed 8 aligned beneath interface of setting-out valve, rotation rotating handle 10 transfer bilge sample bucket 6 to touching relief valve 8, bilge sample bucket 6 Spool open, pin vent valve 5 manually, sample will be drained into sample container by bilge sample bucket 6, so sampling complete.

Under not working condition, bottom spool 26, with 16 close contact of lower valve base, keeps close property under the gravity of clump weight 17, Upper valve core 19, with 15 close contact of upper valve base, keeps the close property in 6 top of bilge sample bucket, entire cabin under the action of holddown spring 23 Bottom sample bucket 6 is totally-enclosed state；When to be sampled, during decentralization, gravity of the bottom spool 26 in clump weight 17 Under, overcome the buoyancy of liquid, still remain off, upper valve core 19 is not by buoyancy, under the action of holddown spring 23 It remains off；Bilge sample bucket 6 reaches the bilge, and bottom spool 26 touches bilge entity opening, and lower guide rod 18 is pushed and led 33 uplink of bar, overcomes the elastic force of holddown spring 23 to open upper valve core 19, and liquid enters the bilge from the lead channel 27 on lower valve base 16 In sample bucket 6, the gas in bilge sample bucket 6 is discharged from the air hole 21 on open upper valve core 19 and hanging hook assembly 20, liquid Body is into after full bilge sample bucket 6, and rotation rotating handle 10 promotes bilge sample bucket 6, and bottom spool 26 is fast under 17 gravity of clump weight Speed is closed, and upper valve core 19 is also switched off under the elastic force effect of holddown spring 23, and the bilge, which obtains sample, will be stored in bilge sample bucket 6 It is interior, it is promoted and arrives protective cover, closed deck valve and carry out setting-out.

The upper valve core 19 and bottom spool 26 of this structure are all closed when not sampling, and when sampling opens simultaneously, and ensure that cabin The airtightness of bottom sample bucket 6 ensure that the bilge sample got is not replaced by supernatant liquid.

There is small gap among top guide bar 33 and lower guide rod 18 designed by this structure, can guarantee upper valve core 19 and lower valve Core 26 simultaneously closes off, and does not interfere with each other；Simultaneously when assembling, bottom spool 26 and lower guide rod 18 are directly loadable into, upper valve core 19 with After top guide bar 33 is packed into, slightly on put on that guide rod 33 is fixed, and assembly is simple, almost not having to debugging can be used.

The operating process of closed bilge sampler provided by the present invention is all closed, prevents cargo tank or fluid reservoir It being communicated with the atmosphere, leakproofness is strong, and it is highly-safe, therefore have very for oils and taking for chemical liquor or volatile liquid Good effect.

Finally, it should be noted that the foregoing is only a preferred embodiment of the present invention, it is not intended to restrict the invention, Although the present invention is described in detail referring to the foregoing embodiments, for those skilled in the art, still may be used To modify the technical solutions described in the foregoing embodiments or equivalent replacement of some of the technical features. All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in of the invention Within protection scope.
