At present, the conventional design scheme is that an overhaul hatch cover is arranged at the top of the liquid cargo tank, the overhaul hatch cover is disassembled when the portable submersible pump is placed, and the portable submersible pump is placed into the liquid cargo tank, so that the design scheme has the following defects:
(1) when the hatch cover is disassembled, the inert gas in the liquid cargo tank can leak out, and the personal safety of operators is influenced;
(2) when the hatch cover is opened, outside air enters the liquid cargo tank, the oxygen content in the tank is increased, the inerting degree of the liquid cargo tank is damaged, and the safety of the FPSO is influenced;
(3) after the hatch cover is opened, a hole is formed on the deck, and the personal safety of operators is influenced.
SUMMERY OF THE UTILITY MODEL
The utility model relates to a lower cabin installation component of portable hydraulic submerged pump when the portable submerged pump of installation, can prevent that the inert gas in the liquid cargo hold from leaking.
In order to solve the technical problem, the utility model provides a lower cabin installation component of portable hydraulic submerged pump, fill water valves, knife gate valve and short tube coupling including seal anchor clamps, isolation capsule, inert gas, seal anchor clamps are installed the upper portion port of isolation capsule, hydraulic submerged pump locate in the isolation capsule, just the overhanging cargo oil pipe that connects on the hydraulic submerged pump passes seal anchor clamps, the lower extreme of isolation capsule with knife gate valve connects, knife gate valve passes through the short tube coupling with wear cabin spare intercommunication, the side-mounting of isolation capsule the inert gas fills water valves.
Furthermore, two through holes are formed in the sealing clamp, so that the cargo oil pipe can pass through the through holes, and the outer wall of the cargo oil pipe is sealed with the inner wall of the through holes.
Furthermore, the short pipe joint is communicated with the knife gate valve through a flange.
Further, the sealing clamp is installed on the isolation capsule through bolts and sealing gaskets.
Furthermore, after the isolation seal cabin is detached from the knife gate valve, a blind plate is installed at the upper port of the knife gate valve.
The technical effects of the utility model reside in that: the utility model discloses cargo oil pipe on the hydraulic submerged pump stretches out through seal anchor clamps, and the hydraulic submerged pump sets up and keeps apart in the sealed cabin, be encapsulated situation between cargo oil pipe and the sealing member anchor clamps, when transferring the hydraulic submerged pump, fill earlier from the inert gas and fill in the valves and fill into nitrogen gas, then open the knife gate valve, because keep apart sealed cabin atmospheric pressure great, can with effectual isolated liquid cargo under-deck inert gas leak and outside air gets into the liquid cargo under-deck, also guaranteed the stability of inertization in the liquid cargo under-deck when having protected operating personnel's personal safety, FPSO's safety has been guaranteed.

Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and can implement the present invention, but the embodiments are not to be construed as limiting the present invention.
As shown in fig. 1-3, an embodiment of the present invention provides a lower chamber installation assembly of a portable hydraulic submersible pump, wherein each step is implemented as follows:
the utility model discloses a seal anchor clamps 1, isolation capsule 2, inert gas fill valves 4, knife gate valve and nipple festival, seal anchor clamps 1 are installed at the upper portion port of isolation capsule 2, and hydraulic pressure submerges pump 3 and locates in the isolation capsule 2, and the overhanging goods oil pipe that connects on the hydraulic pressure submerges pump 3 passes seal anchor clamps 1, and the lower extreme and the knife gate valve of isolation capsule 2 are connected, and the knife gate valve passes through the nipple festival and wears cabin spare intercommunication, the side-mounting of isolation capsule 2 inert gas fills valves 4.
Specifically, the isolation sealed cabin 2 is a hollow tubular structure with two open ends, wherein the sealing clamp 1 is arranged at the upper port of the isolation sealed cabin 2 through a bolt and a sealing gasket; the two cargo oil pipes respectively penetrate out of the through hole of the sealing clamp 1, the outer wall of each cargo oil pipe and the inner wall of the through hole are sealed, and inert gas can be prevented from flowing into the air.
The lower port of the isolation sealed cabin 2 is communicated with a knife gate valve, the other end of the knife gate valve is communicated with a short pipe joint, and the other end of the short pipe is welded at the top of the cabin penetrating piece.
