DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fluid transfer hose for transferring a fluid such as petroleum at sea, and more particularly, to a fluid transfer hose which allows an operator to easily detect internal breakage of the hose. It relates to a transfer hose.

[0002]

2. Description of the Related Art A fluid transfer hose used for transferring a fluid such as petroleum at sea may break down the hose and cause the fluid being transferred to flow into the sea, which may lead to large environmental pollution. Therefore, it is indispensable that the hose has a structure that can quickly detect breakage of the hose.

[0003] Generally, the fluid transfer hose as described above has a structure in which an inner rubber layer, a main reinforcing layer group, an outflow fluid absorbing layer, an auxiliary reinforcing layer group, and an outer rubber layer are sequentially laminated from the inner peripheral side of the hose. Has become. The main reinforcing layer group and the auxiliary reinforcing layer group each have a structure in which a plurality of reinforcing layers formed by rubber-covering reinforcing cords inclined with respect to the longitudinal direction of the hose are laminated such that adjacent reinforcing layers cross the reinforcing cords. The main reinforcement layer group acts as a pressure-resistant layer against the fluid passing inside the inner rubber layer, while the auxiliary reinforcement layer group flows out to the outflow fluid absorption layer due to the damage of the main reinforcement layer group. The leaked fluid is prevented from leaking to the outside.

Conventionally, in the fluid transfer hose described above, when a fluid flows out to the outflow fluid absorbing layer due to breakage of the main reinforcement layer group, the auxiliary reinforcement layer group receives the pressure of the outflow fluid, and the longitudinal direction and diameter of the hose are reduced. There has been proposed a hose having a structure capable of extending and deforming in the direction or twisting and deforming in the circumferential direction. In these hoses, a plurality of lines (stripe) are provided on the surface of the outer rubber layer. These lines are deformed by extension deformation or torsion deformation of the auxiliary reinforcing layer group. By visually inspecting the deformation of the line, the worker can know the damage of the main reinforcing layer group before the fluid being transferred flows out into the sea.

However, since the fluid transfer hose is connected for several hundred meters, even if the auxiliary reinforcing layer group is deformed as described above, the worker may overlook the deformation of the line when viewed from a distance. There is. Moreover, it is extremely difficult to confirm that during nighttime work.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a fluid transfer hose which enables an operator to easily and reliably find a break in a main reinforcing layer group even from a distance or at night. It is in.

[0007]

The present invention for achieving the above object has a hose body in which an inner rubber layer, a main reinforcing layer group, an outflow fluid absorbing layer, and an outer rubber layer are sequentially laminated from the inner peripheral side of the hose.

And a warning means connected to the conductor and generating an alarm by cutting or changing the resistance value of the conductor is provided. Was And wherein the door.

[0008] According to the above structure, when the conductor is cut or the resistance value changes due to the damage of the main reinforcing layer group, the alarm means gives an alarm, so that the worker can be operated even from a distance. Never overlook the damage of the reinforcement layer group. Further, even at night, the worker can easily and surely find the damage of the main reinforcing layer group.

An auxiliary reinforcing layer group 6 is disposed in a tubular shape on the outer peripheral side of the main reinforcing layer group 4 via a tubular outflow fluid absorbing layer 5, and a tubular outer rubber layer 7 is provided on the outer peripheral side.

The main reinforcing layer group 4 has a structure in which a plurality of reinforcing layers formed by coating rubber with a reinforcing cord made of an organic fiber cord obliquely arranged with respect to the longitudinal direction of the hose are laminated. Adjacent reinforcing layers have their reinforcing cords crossing each other with the direction of inclination with respect to the longitudinal direction of the hose reversed, and the main reinforcing layer group 4 is a pressure-resistant layer against the fluid transferred inside the inner rubber layer 3. And acts as a tension-resistant layer. The number of reinforcing layers in the main reinforcing layer group 4 can be, for example, 14 to 20 layers.

The outflow fluid absorption layer 5 is made of sponge rubber, foamed polyurethane, or the like, and serves as an absorption layer that absorbs the fluid that has flowed out due to breakage of the main reinforcing layer group 4 and a float layer that floats the liquid transfer hose H1. It has both functions.

The auxiliary reinforcing layer group 6 has a structure in which a plurality of reinforcing layers formed by coating rubber with a reinforcing cord made of an organic fiber cord that is arranged obliquely with respect to the longitudinal direction of the hose are laminated. The adjacent reinforcing layers have their reinforcing cords intersecting each other with the direction of inclination with respect to the longitudinal direction of the hose being reversed, and the auxiliary reinforcing layer group 6 is composed of the fluid flowing out to the outflow fluid absorbing layer 5 due to the damage of the main reinforcing layer group 4.

The reinforcing cords of the reinforcing layers of the auxiliary reinforcing layer group 6 are as follows:
The reinforcement cord inclined to one side and the reinforcement cord inclined to the other side with respect to the longitudinal direction of the hose have substantially the same inclination angle with respect to the longitudinal direction of the hose, that is, about 55 ° (stationary angle). Even if the auxiliary reinforcing layer group 6 receives the pressure of the outflow fluid due to the damage, the auxiliary reinforcing layer group 6 does not deform. The number of reinforcing layers in the auxiliary reinforcing layer group 6 can be, for example, about 20 layers.

On the outer peripheral surface 4a of the main reinforcing layer group 4, a conductor 9 that can be cut when the main reinforcing layer group 4 is elongated and deformed as described later due to damage of the main reinforcing layer group 4 extends along the longitudinal direction of the hose.
