Description

Technical Field

[0001] The invention relates to the technical field of fire extinguishing devices, in particular to an inert gas fire extinguishing device used for a skid-mounted refueling device. Background Art

[0002] When a fire occurs in a tank of a skid-mounted refueling device, it will cause serious consequences if it cannot be put out in time. However, the current fire extinguishing method mainly adopts external cooling and air isolation. However, when a fire occurs in a tank, if it cannot be put out in time within a short period of time, the pressure in the tank will continue to increase. Once an explosion occurs, the consequences will be disastrous. If a fire occurs in a tank, the oil and gas in the tank can be quickly discharged through the pressure relief pipe, and the oil in the tank can be isolated from the air, then the danger will be greatly reduced.

[0003] Inert gas refers to the gaseous single substance corresponding to all the Group 0 elements on the periodic table. At normal temperature and pressure, they are all colorless and odorless monatomic gases, and it is difficult to undergo chemical reactions. If a fire occurs inside an oil tank, the inert gas can quickly rush into the tank, which can not only press out the oil and gas in the tank, but also isolate the oil from the air, achieving the purpose of rapid fire extinguishing. However, there is currently no mature product for skid-mounted fire extinguishing using this method, and a reasonable design is needed. Summary of the invention

[0004] The object of the present invention is to provide an inert gas fire extinguishing device for use in a skid-mounted refueling device to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned object, the present invention provides the following technical solution: an inert gas fire extinguishing device for a skid-mounted refueling device, comprising a mounting plate, a bottom plate fixedly connected to the lower surface of the mounting plate, a sealed container fixedly connected to the upper surface of the bottom plate, a gas pipeline fixedly connected to the upper surface of the sealed container, a moving assembly symmetrically fixedly connected to the lower surface of the bottom plate, the moving assembly and the sealed container movably matched, a pressing mechanism fixedly connected to the interior of the sealed container, the pressing mechanism and the gas pipeline movably plugged:

[0006] The pressing mechanism includes an electric push rod, which is fixedly connected to a sealed container. The inner wall of the sealed container is symmetrically provided with card grooves, and the surface of the card grooves is movably connected with card blocks. A pressing plate is fixedly provided between the card blocks. The pressing plate is fixedly connected to the electric push rod, and the pressing plate is movably connected to the gas pipe.

[0007] Preferably, one side of the mounting plate is evenly distributed with mounting bolts for rotational connection.

[0008] Preferably, an annular sealing gasket is fixedly mounted on the lower surface of the sealed container, and a valve body is fixedly connected to the surface of the gas pipe.

[0010] Preferably, one end of the pull rod is fixedly connected to a handle.

[0011] Preferably, an annular sealing strip is fixedly mounted on the outer wall of the lower pressure plate, the annular sealing strip is fixedly connected to the clamping block, and the annular sealing strip is movably connected to the sealing container.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. Through the knob valve body, the gas pipeline is in an open state, and the external compressed liquid inert gas is transported to the inside of the sealed container through the gas pipeline. Through the knob mounting bolt, the mounting bolt knob is turned to the fire extinguishing device installation position inside the oil tank, thereby completing the installation of the fire extinguishing device, thereby effectively improving the convenience of fire extinguishing operations in the event of a subsequent fire;

[0014] 2. Pull the two sets of handles in opposite directions to open the electric push rod. The handle drives the pull rod to move, and the pull rod drives the connecting block and the slider to move. The two sets of connecting blocks move in opposite directions and the two sets of fan-shaped cover plates are quickly separated. The piston end of the electric push rod pushes the lower pressure plate downward, and the lower pressure plate drives the annular sealing strip and the card block to move downward. The thrust generated when the lower pressure plate moves downward quickly pushes the inert gas inside the sealed container to the outside of the sealed container, thereby quickly pushing out the inert gas inside the sealed container, thereby effectively improving the speed of fire extinguishing.
