Detailed Description

The following describes in detail embodiments of the present invention with reference to the accompanying drawings.

As shown in the attached drawing, the utility model discloses a fire extinguishing system for FPSO electricity is module between, including base 1's left side be fixed with fire extinguishing agent storage box 2 left wall on open and to have liquid mouth 3 of annotating, liquid mouth 3 of annotating be used for and carry fire extinguishing agent pipeline intercommunication.

A extinguishing device includes shell 4 shell diapire on the interval be fixed with two bearings 5 about, a connecting axle 6 that sets up along the horizontal direction passes two bearings 5 settings connecting axle 6 about both ends be fixed with a sliding roller 7 respectively shell 4's diapire on have a support 8 through the bolt fastening, support 8 through the bolt fastening on base 1. The bracket 8 is detachable by means of a bolt connection, so that the housing 4 can be pulled by means of the sliding roller 7 when moved.

A baffle is fixed in the shell 4 along the horizontal direction, the cavity in the shell 4 is divided into an upper cavity and a lower cavity which are independent from each other by the baffle, the upper cavity is used as an air chamber 9, a rubber tank 10 is installed in the lower cavity, central holes with the same diameter are respectively arranged on the top wall and the baffle of the shell 4, the axis of the central hole is superposed with the central axis of the shell, the lower end of a hollow T-shaped pipe 11 penetrates through the central holes on the top wall and the baffle and is pressed on the top wall of the rubber tank 10, an air inlet valve 12 is connected on the side wall of the air chamber 9 through a pipeline, one end of a liquid inlet pipeline 13 is communicated with a liquid outlet arranged at the lower part of the fire extinguishing agent storage box 2, the other end of the liquid inlet pipeline 13 is sequentially connected with a pressure pump 14 and a stop valve 23 and is communicated with a liquid inlet arranged on the rubber tank 10 through a first mounting hole arranged on the shell, one end of a liquid outlet pipeline 15 communicates with a liquid outlet opened on the rubber tank 10 and the other end passes through a second mounting hole opened on the shell and is arranged outside the shell, the outlet end of the liquid outlet pipeline 15 communicates with the inlet ends of two branches 16 and 17, an electromagnetic valve 18 is installed on each branch, a nozzle 19 and a nozzle 20 are installed on the outlet of each branch, and two optimized nozzles adopt a shower structure to increase the spray area. The pressure pump 14, the electromagnetic valve 18 and the stop valve 23 are all connected with a controller 21 through control lines, and the controller 21 is connected with a temperature sensor 22 arranged on the base 1 through signal lines.

The working principle of the device is as follows:

opening the liquid injection port 3, enabling NOVEC1230 liquid to enter the fire extinguishing agent storage box 2 from the liquid injection port 3, plugging the liquid injection port 3 with a sealing plug after liquid injection is completed, sending an alarm signal when the temperature sensor 22 detects that the liquid injection port is abnormal, transmitting the alarm signal to the controller 21, outputting a control signal to the electromagnetic valve 18 and the stop valve 23 by the controller 21, automatically opening the electromagnetic valve 18 after receiving the control signal of the controller 21, closing the stop valve 23, screwing down the bolt of the bracket 8 and the base 1 to form a portable fire extinguishing device, moving the fire extinguishing device to a fire scene, manually opening the air inlet valve 12 to fill air into the air chamber 9, manually lifting the T-shaped pipe 11 upwards, fixing the contact part of the T-shaped pipe 11 and the shell 4 through a pipe clamp when the lower end of the T-shaped pipe 11 is completely arranged in the air chamber 9, inflating compressed air in the air chamber 9 into the cavity at the lower part, and rapidly starting compression of the rubber tank 10 under the action of air pressure, the NOVEC1230 liquid stored in the rubber tank 10 is compressed and then enters the two branches 16 and 17 through the liquid outlet pipe 15 and is sprayed out through the two nozzles 19 and 20, the NOVEC1230 liquid is quickly gasified after being released to extinguish the fire, the electromagnetic valve 18 can be set to be a manual mode and an automatic mode, the use mode is selected according to the site fire,

after the fire on site is extinguished, the fire extinguishing device is fixed on the base 1 again, the temperature sensor 22 detects that the temperature on site is reduced and then sends a control signal to the controller 21, the controller 21 sends a control signal to the pressure pump 14, the pressure pump 14 is started after receiving the control signal of the controller 21, meanwhile, the stop valve 23 is opened, and the NOVEC1230 liquid stored in the fire extinguishing agent storage box 2 enters the rubber tank 10 through the liquid inlet pipeline 13 to supplement the NOVEC1230 liquid content in time.

The structure that handle and pulley combined together has richened the removal mode of fire extinguisher, has shortened the transportation time of fire extinguisher, has reduced the injury loss on-the-spot. The NOVEC1230 liquid stored in the rubber cylinder is safe and environment-friendly, is non-toxic and harmless after being gasified, plays a good role in protecting the environment, and realizes green, clean and fire-fighting. The double-nozzle and sprinkler structure increases the fire-extinguishing coverage area, improves the fire-extinguishing effect and can quickly extinguish the fire. The device compact structure, easy dismounting, occupation of land space is little, has made things convenient for the transportation of depositing, makes things convenient for the maintenance in later stage simultaneously, has reduced the maintenance cost.
