Here, the inclination to the installation floor does not mean that the installation is arranged substantially parallel to the installation floor, but the inclination is not less than a predetermined inclination including the installation state perpendicular to the installation floor And the like. 1, the pipe connection unit 10 includes a pipe 11, a pipe 11, a pipe 11, a pipe 11, The first flange 12, the second flange 13 and the gap regulating portion 14 that regulates the gap between the first flange 12 and the second flange 13 provided on the first flange 12. The occurrence of leakage in the pipe connecting portion 10 means leakage between the first flange 12 and the second flange 13.

1 to 3, a cover device according to an embodiment of the present invention includes a pair of pipe connection portions 10 that cover the pipe connection portion 10 in a circumferential direction and are removably coupled to each other, The first and second cover housings 100 and 200 and the first and second leak-storage areas 250 and 260, which are provided respectively at the bottoms of the first and second cover housings 100 and 200 and can receive the liquid leaked from the pipe connection part 10, ). Here, the first and second leak storage regions 250 and 260 are partitioned from each other and will be described below. Here, leakage refers to leakage.

The first and second cover housings 100 and 200 are configured to surround the upper end portion of the pipe 11, the first flange 12, the second flange 13, and the gap adjusting portion 14 in the circumferential direction. The first and second cover housings 100 and 200 are detachably coupled to each other. When the first and second cover housings 100 and 200 are coupled to each other and the separate cap 300 is fastened to the upper end of the first and second cover housings 100 and 200, The interior of the cover housings 100 and 200 is hermetically sealed to the outside, thereby preventing external scattering and leakage of gas and liquid leaked from the pipe connecting portion 10. At this time, the lower openings of the first and second cover housings 100 and 200 are in contact with the outer surface of the pipe 11 as much as possible.

In the embodiment of the present invention, the first and second cover housings 100 and 200 have a substantially semicircular cylindrical structure symmetrical to each other. For example, in the first cover housing 100, The second cover housing 200 may be provided with a coupling hole 210 into which the coupling protrusion 110 can be inserted.

The first and second cover housings 100 and 200 are respectively provided with sealing grooves 120 for sealing the inner space of the first and second cover housings 100 and 200 with respect to the outside. A soft ring 130 may be inserted into the sealing groove 120. The inner space of the first and second cover housings 100 and 200 is sealed by the ring 130 when the first and second cover housings 100 and 200 are coupled to each other .

In the embodiment of the present invention, the first and second cover housings 100 and 200 may be made of transparent or semitransparent material so that the operator can visually detect leakage or leakage. For example, the first and second cover housings 100 and 200 are applicable to acrylic or the like.

2, the first and second liquid leakage areas 250 and 260 are respectively provided at the bottom of the first and second cover housings 100 and 200 to receive the liquid leaked from the pipe connection part 10 . Here, the first and second leak storage regions 250 and 260 are separately partitioned from each other. When the operator confirms leakage of the piping connection part 10 and wants to collect the leaked liquid, for example, the first and second cover housings 100 and 200 are separated from each other, and then the first and second leak- The leakage liquid stored in the areas 250 and 260 can be separately collected. In the present invention, since the first and second leakage areas 250 and 260 are separately partitioned from each other, when the first and second cover housings 100 and 200 are separated, There is an advantage that contamination of the surrounding space can be prevented as much as possible.

In the embodiment of the present invention, partition walls 400 are respectively formed below the first and second cover housings 100 and 200 to form the first and second leakage areas 250 and 260, respectively. The first cover housing 100 and the second cover housing 200 are coupled to each other through a pipe through hole 500 so that the pipe 11 of the pipe connecting portion 10 passes through the first and second cover housings 100 and 200. [ .

The partition wall 400 includes a first partition wall 410 forming one side of the pipe through hole 500 and a second partition wall 410 connecting the first partition wall 410 and the outer walls of the first and second cover housings 100 and 200 And includes a second partition wall 420. That is, the first and second leakage areas 250 and 260 are separated from each other by the first partition wall 410 and the second partition wall 420, respectively. When the liquid leaked from the piping connection part 10 drops to the upper surface side of the first partition wall 410 and the second partition wall 420, the first partition wall 410 and the second partition wall 420 are separated from each other, It is possible that the liquid remaining on the upper surface of the container can hardly fall down to the bottom surface. The upper surfaces of the first partition wall 410 and the second partition wall 420 are provided to be inclined downward toward the bottom surfaces of the first and second cover housings 100 and 200, respectively .

1 to 3, at least one rib 600 protrudes from the inner surface of each of the first and second cover housings 100 and 200 so as to be engaged with the upper portion of the flange portion of the pipe connection portion 10 . Specifically, at least one rib 600 is provided so as to cover the upper portion of the second flange 13 of the pipe connection portion 10. In order to mount the first and second cover housings 100 and 200 on the piping connection part 10, the operator first moves one of the cover housings to the appropriate installation position of the pipe connection part 10, The cover housing is engaged. However, in the case of mounting and assembling as described above, the first and second cover housings 100 and 200 are not easy to be fixed, and the coupling position with respect to the pipe connecting portion 10 is also not constant. There arises a problem that the coupling is not easy.

The present invention is provided with at least one rib 600 to compensate for the difficulty in such installation work. The ribs 600 protrude from the inner surfaces of the first and second cover housings 100 and 200 by a predetermined amount or more so that the operator can move the ribs 600 of the first cover housing 100 to the second flange 13), it is possible to prepare for the coupling operation of the second cover housing 200. [ At this time, since the first cover housing 100 can keep the state over the second flange 13 due to the rib 600, the operator can perform the cover housing joining operation more easily, It is possible to quickly assemble to the same position at all times even when it is coupled to a plurality of pipe connection portions 10.

On the other hand, in the above description, the collection of the first and second cover housings 100 and 200 separately for collecting the leakage liquid stored in the first and second cover housings 100 and 200 has been described. However, when the first and second cover housings 100 and 200 are separated from each other in a state where leakage of the piping connection part 10 is continuously generated, there is a problem that the liquid leaking from the piping connection part 10 falls down to the surrounding floor Lt; / RTI > In order to solve this problem, the present invention provides a structure capable of collecting leakage liquid stored therein without separating the first and second cover housings 100 and 200 from each other.

4, the bottom surfaces of the first and second cover housings 100 and 200 forming the bottoms of the first and second leak-storage regions 250 and 260 are formed on the outer side of the first and second cover housings 100 and 200 And gradually downwardly inclined toward the direction.
