Description

  The present invention relates to a fluid leakage prevention cover. In particular, the present invention relates to a leaked fluid outflow prevention cover structure for preventing fluid such as oil leaked from a pipe installed in a power plant or substation from flowing out of the ground or the like.

  For example, in a power plant or a substation, a transformer with a radiator is installed. And a transformer main body and a radiator are connected with an oil feed pipe, and the transformer main body is cooled by circulating the oil cooled with a radiator between the transformer main body and a radiator.

  Such a transformer with a radiator includes a first flange provided at an end of a first oil feeding pipe extending from the transformer main body side, and a radiator for easily separating or connecting the transformer main body and the radiator. And a second flange provided at the end of the second oil feeding pipe extending from the side, and the first flange and the second flange are connected by a bolt member via a packing.

  By the way, when the packing deteriorates due to secular change or the like, there is a concern that oil leaks from between the first flange and the second flange, and the oil flows out to the ground. In such a situation, there is a concern that the oil penetrates into the ground and becomes a remote cause of contaminating soil or water quality.

  In order to prevent the above-described situation, a pair of semi-cylindrical transparent covers that covers the periphery of a pair of flanges connected to each other in a sealable manner and an adsorbent for oil that can be accommodated inside the pair of transparent covers An oil leakage prevention cover is disclosed (see, for example, Patent Document 1).

  The oil leakage prevention cover according to Patent Document 1 is configured such that one end portions of a pair of transparent covers are rotatably connected, and the other end portions of the pair of transparent covers are configured to be openable and closable. By attaching a lock operating lever and attaching a latch to the other end of the other transparent cover, the pair of transparent covers can be opened and quickly introduced into a set of flanges.

  As similar to the oil leakage prevention cover disclosed in Patent Document 1, when the outer periphery of the pole transformer containing the insulating oil is damaged by a lightning strike, and the insulating oil leaks, the leakage portion is covered, A fluid leakage prevention cover that can prevent the insulating oil from flowing out is disclosed (for example, see Patent Document 2).

  The fluid leakage prevention cover according to Patent Document 2 includes a bottomed cylindrical transparent cover, a ring-shaped packing that is attached to the peripheral edge of the opening end of the transparent cover, and can be in close contact with the outer periphery of the pole transformer, and the inner wall of the packing A disc-shaped oil adsorption mat fitted to the two ends, and one end portion moored to the middle portion of the transparent cover, and the other end portions can be moored together so as to extend and adhere to the outer periphery of the pole transformer. A pair of rubber cords.

  In the fluid leakage prevention cover according to Patent Document 2, the oil adsorption mat is brought into contact with the leakage portion of the pole transformer, the other ends of the pair of rubber strings are moored together, and the leakage portion is pressed with the oil adsorption mat. By accommodating the leaked insulating oil inside the transparent cover through the adsorption mat, the insulating oil can be prevented from flowing out.

  When oil leakage is detected or detected from a pipe installed in a power plant or substation, it is necessary to immediately prevent the oil leakage from flowing out of the ground or the like. In this case, it is often difficult to immediately perform a so-called complete recovery in which oil leakage is prevented by replacing parts at the oil leakage location. It is necessary to implement a so-called first-aid measure to prevent the oil leak from spilling out to the outside such as the ground.

  It is also effective to take emergency measures, such as closing the oil spill area with a waste cloth or installing a tray to collect the oil spill. However, if the oil leakage prevention cover according to Patent Document 1 or the fluid leakage prevention cover according to Patent Document 2 is prepared, it is considered that the leakage of oil to the outside can be prevented quickly and reliably.

  However, the oil leakage prevention cover according to Patent Document 1 is configured such that the inner diameter of the pair of transparent covers is in close contact with the periphery of the oil feeding pipe. It is necessary to prepare an oil leakage prevention cover.

  A large number of oil pipes are arranged in a power plant or substation. In addition, it is generally difficult to predict oil leakage from these oil feeding pipes, and preparing a plurality of types of oil leakage prevention covers has a problem of high economic burden. There is a need for a versatile leakage prevention cover that can accommodate oil pipes with different outer diameters.

  On the other hand, since the fluid leakage prevention cover according to Patent Document 2 is closed around the tubular body with a set of elastic rubber strings, it can accommodate oil supply pipes having different outer diameters. However, the fluid leakage prevention cover according to Patent Document 2 is considered to be difficult to prevent oil leakage with a disc-shaped oil adsorption mat when a crack occurs along the outer diameter direction of the oil feeding pipe. This is because the flat surface of the oil adsorption mat is in contact with the curved surface of the oil feeding pipe. There is a need for a versatile leakage prevention cover that can deal with cracks in the outer diameter direction of an oil feeding pipe. The above can be said to be the subject of the present invention.

  The present invention has been made in view of such a problem, and is a leaked fluid outflow prevention cover for preventing fluid leaking from a tube from flowing out to the outside, so that it can cope with tubes of different outer diameters. Another object of the present invention is to provide a versatile leakage prevention cover for leakage fluid.

  The inventors have a set of belt-shaped belt members that can be attached to the outer periphery of a tube having an incompressible fluid therein, and a bendable accordion that repeats a mountain fold and a valley fold on a pair of opposing side and bottom surfaces. A box-shaped cover member having a structure constitutes a leakage prevention cover for leakage fluid, a guide member is disposed along the longitudinal direction of the belt member, and the cover member is guided by a pair of guide members. A plurality of ring members are arranged at the open end, and the open end of the cover member is brought into close contact with the outer periphery of the pipe, thereby finding that the leaked fluid can be collected inside the cover member so that it can be used for pipes having different outer diameters. Based on this, the inventors have invented the following new leakage prevention cover for leakage fluid.

  (1) A leaked fluid outflow prevention cover according to the present invention is a leaky fluid outflow prevention cover capable of preventing an incompressible fluid leaking from the inside of a pipe from flowing out to the outside, with a tip fitting at one end.

The guide member is disposed at one end in the width direction, and the cover member includes a pair of ring members guided by the guide member in a state where the pair of guide members are opposed to each other. At the open end of the side, Serial cover member freely recovering the fluid therein, it can be in close contact with the opening end on the outer periphery of the tube.

  (2) It is preferable that the plurality of ring members are arranged at least at the four corners of the opening end of the cover member.

  (3) The belt member has a plurality of locking holes arranged along the longitudinal direction thereof, and a pin-shaped clasp that is disposed in the buckle and can be locked to the locking hole. Is preferred.

  (4) The guide member may be a linear body that can be bent.
