In addition, the float may have a specific gravity larger than air and a specific gravity smaller than that of the residual gas so as to be positioned at the interface between the air and the residual gas.

The display unit may further include an opening / closing unit that closes the opening of the display tube to protect the floating body from the liquid when the liquid is stored in the closed space.

Further, the display tube includes a tube having a moving space in which the floating body is located; The tube may have an incision in the longitudinal direction.

The display tube may include a tube having a moving space in which the floating body is located; A first opening formed at the lower end of the tube; And a second opening formed at the top of the tube, the opening and closing portion being located below the first opening and including a float for opening and closing the first opening by buoyancy.

In addition, the opening / closing portion may include an opening that extends from the float, is located in a moving space of the tube through the opening, and provides a gas moving passage for allowing gas flow to the moving space when the float opens the first opening .

According to the embodiment of the present invention, the floating body is lifted depending on the height of the residual gas in the harmful work space having the closed space, so that the operator has a remarkable effect of confirming safety through the float height.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the like elements throughout. The description will be omitted.

FIG. 1 is a perspective view showing a residual gas display device according to a first embodiment of the present invention, and FIGS. 2 and 3 are views showing an example of using a residual gas display device installed on a side wall of a cargo tank.

Referring to FIGS. 1 to 3, the residual gas display device 10 according to the first embodiment of the present invention may include a display tube 100 and a float 200.

The display tube 100 may be installed vertically in a cargo tank such as a tanker line or an FPSO. The display tube 100 may be provided with a movable space 102 in which the float 200 can move and the upper and lower openings so that the residual gas and air in the cargo tank 20 can freely flow . In addition, the display tube 100 is preferably made of a transparent material so that the operator can visually confirm the float 200. The display tube 100 may provide the incision 110 in the longitudinal direction so that the float 200 can be easily seen.

The display tube 100 has been illustrated and described in the form of a circular pipe in the present embodiment, but it is not limited thereto and may be provided in various shapes in which the floating body can move.

The float 200 may have a spherical shape. The float (200) is located in the moving space (102) of the indicator tube (100). The float 200 is a kind of balloon filled with a gas therein, and the sum of the weight of the float 200 itself and the weight of the fill gas in the float 200 is located at the interface between the residual gas in the cargo tank 20 and the air And the like. In other words, the float 200 can be made to have a specific gravity larger than that of the air and smaller than the residual gas so as to be positioned at the interface between the air and the residual gas.

The float (200) may be coated with a luminous paint for securing visibility, or the float itself may have luminous properties.

In this embodiment, the float 200 is shown as having a sphere shape, but the shape of the float is not limited thereto and may be provided in various forms such as a polyhedron or an ellipse.

2 and 3 show an example in which the residual gas display device according to the first embodiment of the present invention is installed perpendicularly to the side wall of the cargo tank.

 2 and 3, when residual gas having a specific gravity heavier than air is present in the cargo tank 20, the residual gas is positioned below the air, and the float 200 of the residual gas display device 10 remains And floats on the interface between gas and air. Therefore, the operator can check the residual gas to a certain height in the cargo tank 20 through the floating height of the float 200, and perform the operation in the tank only when the residual gas is within the safe range .

Fig. 4 is a view showing another use example of the residual gas display device. Fig.

As shown in FIG. 4, when the ladder or the step 30 is formed in several stages in the cargo tank 20, it is difficult for the operator to visually confirm the residual gas display device installed on the side wall of the tank 20. In this case The residual gas display device 10 may be inclined along the inclination of the step 30 or may be installed in the step 30 directly in multiple stages.

FIG. 5 is a perspective view showing a residual gas display device according to a second embodiment of the present invention, and FIG. 6 is a sectional view of the residual gas display device shown in FIG.

Referring to FIGS. 5 and 6, the residual gas display device 10a according to the second embodiment may include a display tube 100a, a float 200, and an opening / closing part 300. FIG.

Here, the float 200 has substantially the same configuration as the float 200 mentioned in the residual gas display device 10 of the first embodiment.

However, the residual gas display device 10a of the second embodiment is different from the residual gas display device 10 of the first embodiment in that the floating fluid 200 is contaminated by liquid stored when a liquid such as oil is stored in the cargo tank It is possible to prevent the occurrence of the problem.

For example, the display tube 100a includes a tube 140 having a moving space in which the float 200 is positioned. A first opening 144 is formed at the lower end of the tube 140, An opening 142 is formed.

The opening and closing part 300 has a structure capable of opening and closing the first opening 144 by being floated by the oil stored in the cargo tank 20. For example, the opening and closing part 300 may include a float 310 and an opening 320.

The float 310 is located below the first opening 144 and has buoyancy to allow the first opening 144 to be opened and closed by buoyancy. The openings 320 extend upwardly from the top surface of the float 310 and are located in the moving space of the tube 140 through the first opening 144.

As shown in FIG. 6, the open portion 320 provides a gas flow passage so that the float 310 opens the first opening 144 to allow gas flow to the moving space.

7 is a view showing a state in which the first opening is closed by a float.

As shown in FIG. 7, when oil is stored in the cargo tank after the residual gas display device 10a is installed in the cargo tank, the float is floated by the oil and blocks the first opening 144. Accordingly, since the oil does not flow through the first opening, it is possible to prevent the floating body from being contaminated by the oil.

The description above is merely illustrative of the technical idea of the present invention, and various changes and modifications may be made by those skilled in the art without departing from the essential characteristics of the present invention. Therefore, the embodiments disclosed in this specification are intended to illustrate rather than limit the technical idea of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas which are within the scope of the same should be interpreted as being included in the scope of the present invention.
