In a plurality of extension ends (121a ~ 121n) is made of a structure in which the extension arm 120 is extended while unfolding.

At this time, in the embodiment of the present invention, four expansion arms 120 form a cross shape with respect to the central body 110 and are exemplified as forming a blocking wall in the vertical direction, but the number of expansion arms 120 is limited thereto. not, and various numbers of expansion arms 120 may be extended based on the central body 110 .

And each extension end (121a ~ 121n) is made of a plate shape, is composed of a pair of partition walls (122, 122') formed to be spaced apart from each other to form an internal space.

The plurality of extension ends 121a to 121n have a central end 121a having one side connected to the central body 110, and the elastic member 130 in a state accommodated in the inner space of the central end 121a. It is composed of one or more unfolding ends 121n that extend the extension arm 120 while sliding to the other side of the central end 121a by the

Here, the unfolding ends 121b, 121c, ..., 121n are at the first unfolding end 121b disposed adjacent to the central end 121a when the extension arm 120 is extended, and the first unfolding end 121b. It may be composed of an adjacently arranged second unfolding end 121c, and an nth unfolding end 121n that is formed in the same structure as this and is in close contact with the inner wall of the tank.

Here, n is a natural number of 1 or more, and the number of the deployment ends 121b to 121n may be varied according to the length constituting the extension arm 120 , so the number of the deployment ends 121b to 121n is not limited, and at least one It is preferable that it is the unfolding end 121n.

More specifically, in the inner space of the central end 121a, a plurality of unfolding ends 121b to 121n may be inserted and accommodated in a state in which the elastic member 130 is contracted, and the elastic member 130 is elongated. As a result, the expansion arms 120 are deployed as the expansion ends 121b to 121n slide to the other side of the central end 121a.

In addition, a fixing member 140 that passes through each coupling hole 124 at the same time and restricts the movement of the plurality of extension ends 121a to 121n may be mounted in the coupling hole 124 .

In this case, the fixing member 140 may be formed of a member such as a fixing pin or a bolt and a nut passing through each of the coupling holes 124 at the same time.

In addition, the coupling holes 124 may be respectively formed on the upper and lower sides of the extension ends 121a to 121n, but the formation position and number of the coupling holes 124 is not limited thereto.

The fixing member 140 passes through the plurality of extension ends 121a to 121n at the same time and can fix the contracted state of the extension arm 120 and the elastic member 130, so that the baffle 100 according to the present invention can be fixed. ) can be stored in a small volume when not in use and has excellent portability, and when in use, only the operation of releasing the fixing member 140 expands the expansion arm 120 by extension of the elastic member 130 and at the same time expands the tank 200 ) Since it is fixed in close contact with the inner wall, there is an advantage that it is easy to install in the tank 200 .

In addition, the baffle 100 according to the present invention is not limited to the configuration of the coupling hole 124 and the fixing member 140 as a means for fixing the reduced state of each expansion arm 120 .
