Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite transmission line connection processing apparatus used for transmission / reception wiring of measuring instruments for remotely measuring by wire. Among measuring instruments, there is a measuring apparatus in which a main body and a part of an operating part are formed separately for various reasons, and the main body is operated at a place separated from the main body. For example, when used in an environment where radio waves are not transmitted, such as underwater, it is common to connect the device main body and the operating unit by wire. The transmission line, which suspends the operating part and extends underwater, has a heavy structure combined with a foreboding to increase its strength, and a light-weight, easy-to-handle conductor connected to the ground equipment body. The composite transmission line is connected on the ground.

[0002]

2. Description of the Related Art A connection method between such a measuring instrument body and an operating unit is described by taking a towing type ocean observation device as an example.
A conventional transmission line winding apparatus will be described with reference to FIGS. The conventional composite transmission line connecting device shown in FIGS. 1 to 3 is a device invented by the present applicant and the inventor shown in Japanese Patent Publication No. 57-60678, and the present invention is an improvement of this conventional device. It was done.

[0003] Reference numeral 1 denotes a measuring ship, and a cable drum 2 driven by a winch (not shown) is provided on the rear deck of the measuring ship 1. At the outer end of the composite transmission line 3 cable wound around the cable drum 2 lowered into water, an ultrasonic sensor as an ocean observation device operating unit 5 is provided.
A sensing unit comprising a depth sensor, a temperature sensor, an accelerometer, and a direction sensor is engaged. In the structure of the composite transmission line 3 cable, the navigation cable for the operating section 5 and the required transmission line leading to the operating section 5 are formed as a single unit. On the other hand, a measuring section as an instrument body 7 of the ocean observation device is installed in a measurement room 6 on the ship, and a fixed conductor 9 connects between the instrument body 7 and a connection box 8 attached to the rear deck. In addition to being connected, the connection box 8 is provided with a conducting wire 10 made of a flexible wire.

[0004] The conductor 1 of the connection box 8 is attached to the cable drum 2.
A small-diameter sub-drum 14 for winding 0 is formed coaxially and integrally with the sub-drum 14. The sub-drum 14 has a sufficient margin length, that is, the number of rotations of the cable drum 2 required to extend the entire length of the transmission line 3. A conductive wire 10 having a length obtained by multiplying the diameter of the drum 14 and the pi by １ ／ is wound around, and
The winding proximal end 10 a is inserted into the inner hole of the hollow drum shaft 15 and is connected to the proximal end 3 a of the transmission line 3 similarly inserted into the inner hole of the drum shaft 15. In the case where the conductive wire of the transmission line 3 and the conductive wire 10 are formed by a single continuous line, there is no connection.

In addition, in the middle of the conducting wire 10, the auxiliary drum 1
Below 4, it penetrates through the side plate of a receiving box-shaped wire reservoir 16 fixed to the deck or lower part. As a result, the extra portion of the conductor 10 descending from the sub-drum 14 is stacked in the conductor reservoir 16.

[0006] Since the conventional composite transmission line connection device such as a remote measuring device is configured as described above, a fixed conductor 9, a conductor 10, and a transmission line are provided between the input of the equipment body 7 and the output of the operating unit 5. The electrical connection is maintained by a series of fixed connections of the conductive wires of the wire 3, thereby eliminating the occurrence of noise and the problem of signal deterioration, and obtaining good and stable conductive characteristics.

[0007] By the way, the conductor 10 fed from the sub-drum 14 is naturally hung up on the conductor reservoir 16 at low speeds without any trouble. However, if the speed is higher than that, the conductor 10 will rise or float at various points on the winding drum portion of the sub-drum 14 unless the operator performs the operation according to the drooping of the conductor 10, and furthermore, In order to minimize the occurrence of protrusions and protrusions from the flange of the drum 14, the number of workers is further increased in order to minimize the occurrence of such problems, and problems such as slippage and catching with the conductor 10 at the time of driving rotation of the cable drum 2 during driving rotation of the cable drum 2. To
There was a need for quick and clean processing.

[0008] Even if it is properly separated, it is difficult to perform continuous and stable work for a long time. During the work, the conductor 10 is subjected to excessive bending or load, and is deteriorated due to damage or bending habit. And unnecessary reflection of light from such parts may cause troubles in good data transmission or cause mechanical and electrical failures. In addition, in such a wrapping, the wrapping around the sub-drum 14 becomes uneven,
Since the weight distribution and winding alignment of the winding drum of the sub-drum 14 are also non-uniform, the cable of the winding drum is displaced, slackened, and kinked with the rotation of the drive of the cable drum 2, thereby hindering the rotation of the drum. After all, it ends up in a state where the winding operation cannot be performed.

[0009] In addition, these operations require extra manpower, and the handling of the cable drum 2 and the tensioned conductor 10 during high-speed rotation increases the danger during the operation. In the case where the sea pattern becomes stormy in the middle of the course and the ship is shaking, the maneuvering operation at high speed rotation is extremely dangerous. In particular, when the ship is moving by hand, or when the conductor 10 or the like is secured by hand, its own body floats in the air at the time of swaying, so that its standing is not effective. The lead wire 10 is dragged down onto the deck together with the lead wire 10, which not only damages the lead wire 10 but also puts a danger to the worker, and thus poses a safety problem. Also, the work
It is convenient to perform it during the daytime during the daytime, and in the case of low-speed rotation, the operation rate of the device is reduced accordingly, which leads to a reduction in the efficiency of the measurement operation. However, in recent years, there has been a demand for an increase in the exploration area, an increase in the exploration depth, and an improvement in reliability, and these improvements must be achieved while paying attention to safety.

[0010] Further, on the deck for performing maintenance and adjustment work, various additional devices and the like have been added to expand the measuring capability of the exploration device, and the capability has been greatly improved compared to the conventional device. The equipment becomes heavier and larger, and it is necessary to install crane equipment on the deck to recover the equipment. Therefore, the working space on the rear deck is gradually narrowing. Therefore, studies have been proposed to minimize the area occupied by the cable drum on the deck.

[0011]

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems,
In a wind-up device for a transmission line cable of a remote sensing device that remotely measures the underwater using a cable, the increase in the area occupied by the cable drum on the deck is eliminated, and safety is ensured regardless of the rotation and speed of the cable drum. It is an object of the present invention to provide a built-in type composite transmission line connecting device in which highly reliable electrical connection and optical connection are maintained. The present invention relates to Japanese Patent Application No. 2000-35962 based on the applicant's earlier application.
0 is an improvement of the invention, in which the area occupied by the cable drum on the deck is reduced.

For this reason, there is no fear of signal deterioration, and if there is an unclear part of the observation data,
By extending the composite transmission line 3, the navigation speed can be relatively reduced immediately, and the influence of the flow noise that increases with the sixth power of the navigation speed can be avoided, and the determination can be made in a good condition where the received signal can be distinguished. This makes it possible to improve the reliability of the acquired data. Furthermore, it is possible to achieve effective acquisition of observation data and expansion of the search area without inefficiency such as re-entering the search sea surface and resuming the search operation to collect data again. This reduction in man-hours and expansion of the exploration area has significant economic effects. In addition, although the sophistication of the exploration equipment has been improved, the inspection and maintenance prior to its introduction is extremely important, and it is necessary to carry out the inspection on the deck quickly, and for that purpose, the work space on the deck is required. Presence or absence has a significant effect on the operation of the exploration area.

8, the optical transmission line 10B drawn from the driven (stationary) sub-drum is transferred to the stationary (driven) sub-drum while rotating on the circumference thereof, and a back tension-added turn is provided for rewinding and aligning. The functional configuration of the cable traverser 20 with the optical device 22 allows the optical transmission system conductor 10B to be smoothly taken in and out, thereby preventing damage and disconnection of the optical transmission system conductor 10B due to turbulent winding and cutting into gaps. It is possible to eliminate the manual operation of conducting wires, which has been conventionally performed, and also to make the manual operator unmanned. Therefore, it greatly contributes to labor saving and eliminates the need to worry about safety, so that the person in charge can concentrate on the exploration, and a substantial exploration can be performed for a long time.

In addition, there is no need to perform the work of manually aligning unlike the conventional apparatus, and the reliability, safety and work efficiency are greatly improved. In addition, since the above device is provided in the hollow portion of the winding drum of the cable drum together with the slip ring mechanism of the current-carrying system, the device can be significantly reduced in size as compared with the case where the device is provided on the outer end surface of the winding drum portion of the cable drum. The work area on the deck is greatly increased. Regarding the electrical conductivity, the adoption of a technically established slip ring mechanism can significantly reduce the number of inspection / adjustment work and maintenance work.

Further, since the two required parts, one of which moves, are optically connected by fixed coupling, good and stable optical transmission characteristics can be obtained, and the performance and weather resistance of the remote probe can be improved. There is also an effect of improving the usability of the device and an effect of improving the usage, safety and labor saving of the winding device.

In addition, there is no electromagnetic interference, and multi-channel optical receiving array transmission has become possible, and satisfactory measurement can be performed even during the rotation operation of the cable drum.

The winding processing section can be arranged separately in the hollow portion of the winding drum of the cable drum, so that the winding operation by the cable drum is stabilized and the number of directly connectable composite transmission lines can be set more. The number can be greatly increased, the signal processing can be simplified, and the search performance and search efficiency can be particularly improved. In addition, since a processing device is provided in the hollow part of the cable drum winding drum, the cable drum can be reduced in size, the area occupied on the deck can be significantly reduced, and the work area can be widely used. Can be effectively implemented in a short time. As a result, safety is improved, man-hours are significantly reduced, and operability is greatly improved.
