Description

[Detailed description of the invention] (Technical field of the invention) The invention relates to an instrument that houses a measuring instrument, etc.
In particular, the present invention relates to a long measuring instrument mounting structure for attaching to long objects such as cables and ropes.

(Prior technology) A measuring device is attached to a long object such as a submarine cable or rope in advance to measure external environmental conditions such as temperature in the sea or the atmosphere, or to measure the magnetic field generated by the current flowing through the submarine cable. Electrical properties such as electrical properties may be measured.

Generally, the measuring device itself is not structured to be attached to a long object. Therefore, a mounting fixture for a long object that can accommodate the measuring device and can be attached to the long object is required.

FIG. 2 is a sectional view of a conventional fixture, with FIG. 2a showing a longitudinal sectional view in the longitudinal direction and FIG. 2b showing a transverse sectional view along the Z-Z' axis.

In the figure, 1 is a fixture made of an elastic material such as rubber or plastic material, 2 is a space for accommodating a measuring instrument (not shown), and 3 is a cable 7.
The measuring instrument is housed in the gap 2 divided along the y-y′ axis, the cable is housed in the gap 3, and the divided fixture 1
It was fastened with metal fittings etc.

Since the cable 7 is usually long, it is wound up and stored on a drum or the like.

Figure 3a is a conceptual diagram when winding up the cable with the conventional attachment 1 attached, and Figure 3b is the cable 7.
Figure c shows a front view when the egg-shaped fixture 1 is rolled up. As shown in Figure 3a, cable 7
When winding up the cable 7, the cable 7 is passed between a plurality of rollers 6 whose upper and lower rotation directions are different in order to apply tension to the cable 7 and to relax the tension as much as possible.

(Problem to be solved by the invention) However, in the conventional fixture 1, the cable 7 applying tension is not in the center position and has an egg-shaped shape, so when passing between the rollers 6, the distance between the rollers 6 is Due to the rapid spread, sudden pressure was being applied to the measuring instrument and roller 6. Also, the contact surface between the cable 7 and the roller 6 when only the cable 7 passes between the rollers 6 as shown in FIG. 3b, and the contact surface between the cable 7 and the roller 6 when the mounting device 1 passes between the rollers 6 as shown in FIG. Since the contact surface between the cable 7 and the roller 6 is different, the stability when passing the roller 6 deteriorates, and the roller 6
It was necessary to increase the width (horizontal length).

(Means for solving the problem) The present invention was made to solve the problems of the prior art described above, and it allows the measuring device to pass between the rollers stably without applying sudden pressure. The purpose of the present invention is to provide a measuring instrument mounting structure for long objects.

(Structure of the invention) The present invention is characterized by having a accommodating part for accommodating the measuring instrument with the cable placed approximately in the center position, and a boot part on one side of the accommodating part that becomes smaller in diameter as it goes away from the accommodating part. That's true.

The present invention will be explained in detail below using the drawings.

FIG. 1 is a schematic diagram of the mounting structure for measuring instruments for long objects according to the present invention, and FIG. 1a is a longitudinal sectional view;
Figure b shows a sectional view along the y-y' axis.

In the figure, 2 is a space for accommodating a measuring instrument, 3 is a space for accommodating a long object such as a cable, 4 is a space for reducing the weight of the mounting device 10, and 5 is a divided accommodating section to be described later. 10a and boot part 1
The groove 10 used for joining 0b is a mounting structure for a long object, which is composed of a cylindrical housing part 10a for accommodating a measuring instrument and a conical boot part 10b for accommodating a long object such as a cable. Also, y− in the figure
The y' axis indicates the dividing (plane) direction of the housing portion 10a and the boot portion 10b.

As shown in the figure, this invention creates a half-split groove (void) on the division.
After accommodating a measuring instrument (not shown) in 2 and placing a long object in the half-split groove (gap) 3 on the split surface, the split surfaces are aligned and the outer periphery of the accommodating part 10a and the boot part 10b is coated. It has a structure in which it is captured by, for example, a band placed in a plurality of grooves.

Therefore, if at least the boot portion 10b is arranged in the direction in which the roller 6 is first rolled up, since the boot portion 10b has a conical shape, the roller 6 will gradually expand and pass through the storage portion 10a. Sudden pressure is not applied to the measuring instrument or roller 6.
In addition, in the present invention, since the elongated object to which tension is applied in advance is placed at the center position of the storage section 10a and the boot section 10b, the long object is placed between the rollers 6 and the storage section 10a and the boot section with different diameters. Even when the roller 10b passes, the contact surface of the roller 6 is almost the same, and the fixture 10 can be passed stably. Furthermore, since the cavity 2 that accommodates the measuring instrument and the cavity 3 that accommodates the long object are divided, the measuring instrument and the long object can be easily installed without penetrating the measuring instrument and the long object into the fixture 10. You can place things.

In addition, the fixture 10 may be made entirely of a resilient rubber material, or the boot portion 10b may be made of a material such as highly elastic rubber, and the housing portion 10a may be made of a plastic material to protect the measuring instrument from external pressure. The boot portion 10b and the accommodating portion 10a are separated from each other, so that even if bending stress is applied, the bending stress applied to the measuring instrument can be reduced.

Note that if the measuring instrument is extremely small or does not receive much bending stress, the accommodating part 10a and the boot part 10b may have an integrated structure and be made of the same material. Moreover, the voids 4 for reducing the weight of the accommodating portion 10a are not necessarily required, and may be provided in any number depending on the weight of the accommodating portion 10a. Further, although two gaps 2 are provided in the measuring device to make the gap 2 bilaterally symmetrical on the dividing plane, this number is also arbitrary.

Further, by arranging the boot portions 10b on both sides of the storage portion 10a, the boot portions 10b can be wound up from either direction, but if the winding direction is only one, at least one boot portion on the winding direction side is sufficient. .

(Effect of the invention) As described above, the present invention allows the long object to be located at the center, and by arranging at least the conical boot part 10b on one side of the storage part 10a, the measuring instrument is It can be stably passed between the rollers 6 without applying pressure.

By configuring the mounting device 10 by separating the housing part 10a and the boot part 10b, the housing part 10
It is possible to reduce the bending stress applied to the measuring instrument inside a.

By providing the boot portions 10b on both sides of the accommodating portion 10a, it is possible to cope with winding from both directions. By using different materials for the boot portion 10b and the housing portion 10a, the mounting device 10
It is possible to reduce the bending stress applied to the

Divided housing section 10a and boot section 10
By forming a groove 5 on the outer periphery of b and tightening the band in the groove 5 to join the divided surfaces, the divided surfaces can be easily aligned, and the diameter of the outer periphery of the housing portion 10a and the boot portion 10b can be increased. It can be configured so that it does not need to be done.
