Description

  The present invention is, for example, an observation apparatus that carries out remote underwater observation while feeding the observation equipment far away from the hull from the stern of a test ship as a measurement ship through a composite transmission line cable as a composite transmission line. In the middle, there is a tow expander as an optical, electrical and mechanical connection, followed by a high performance capability that is demonstrated based on the horizontal stable tow of an observer having an array sensor group as an underwater signal sensor In particular, the present invention relates to a cable drum device of an orthogonal rotation axis type for causing an unnecessary twisting operation induced in a composite transmission line to be maintained for a long time.

  When performing remote underwater observation at a required depth below the surface using a ship, as shown in FIG. There is a composite transmission line cable 1 to reach the required depth depending on the length and ship speed, and it forms an underwater vehicle connected optically, electrically and mechanically, and transmits sound waves in the required direction. There is a tow expander 2 that incorporates a sound source unit 3 that is attached to a horizontal wing 4 and is followed by a sensor group 5.

As a composite transmission line cable 1 as described above, an optical transmission line conductor, an energization line conductor and electric power for towing from a measurement ship with a long, small diameter and heavy specific gravity and reaching the required depth depending on the feed length and ship speed There is a composite transmission line cable 1 in which a system conducting wire is covered with a steel wire and the outer periphery is covered with a sheath, and the applicant of the present application is a cable described in Patent Document 1 below as an apparatus for winding up such a composite transmission line cable 1. A drum device is proposed.
JP 2002-362837 A

  When the composite transmission line cable 1 is coiled and wound around a cable yard or the like of a land facility after manufacture, twisting is induced at a rate of once for each coil winding of the cable. This is wound around the cable drum of the measurement ship by manual feeding, etc. as usual, and then enters the test area and rotates the cable drum to bring the composite transmission line cable 1 to a predetermined length. When carrying out payout and towing, the torsion of the cable, which is called a cable firewood, gradually shifts to the towing expander 2 side, and if the roll moment is larger at that time, the tow expander 2 Rotates and the cable is untwisted. If the roll moment is smaller, the tow expander 2 is tilted to one side and is towed depending on the degree of the roll moment.

  In this state, conventionally, when a sensor group to which an acoustic sensor is attached is followed singly, the sensor group is acoustically omnidirectional, so that there is no significant influence on the performance. There is almost no problem with optical transmission and mechanical strength.

  However, in recent years, the tow expander 2 in the underwater area is intended to improve S (signal) / N (noise) on both the sound source side and the sensor side, which is a higher level of recent underwater observation. In addition to giving sharp directivity to the stored sound source 3, the transmission power is further increased by applying a higher electric power, and ultrasonic waves are transmitted from the sound source 3. At the same time, the sensor group 5 that has been improved in performance by attaching a large number of optical receiving sensors to receive all signal sounds from the seabed 68 etc. of the transmitted sound 7 to the weak echoes is further expanded. The underwater signal sensor is configured by arranging a plurality of (three), and arranging the sensor groups 6 in the both ends and the center of the horizontal wing 4 of the tow expander 2. As a result, the effect of the array gain is added, and the S / N can be further improved. As a result, the performance of the apparatus can be improved. The array sensor group 6 can also be used exclusively for listening to receive incoming radiated sound. The composite transmission line cable 1 in this case is difficult to connect using a conventional slip ring due to a plurality of systems of power system, current system cable and multi-channel optical transmission system.

  In the case of a conventional underwater signal sensor consisting of a single sensor group, the twist of the composite transmission line does not involve any mechanism, and in addition to being naturally performed by the rotation of the towing expander itself, Due to the non-directionality of the horizontal plane of a single sensor group, it was able to operate effectively without degrading the performance regardless of the attitude tilt of the tow expander. From the viewpoint of acoustic performance, it is indispensable to ensure stable and horizontal towing of the tow expander and the following three sensor groups.

  As the towing expander 2 is engaged with the horizontal wing 4 and the resistance of the three sensor groups 5 that follow is increased, the stability is expected to increase as a result. It is not possible to easily expect the behavior to naturally untwist by the twisted back rotation of the cable itself. Further, when the tow expander 2 rotates due to the behavior of each sensor group 5, the subsequent sensor group 5 is complicatedly entangled, and there is a situation in which it cannot be recovered due to the positional displacement and disconnection failure of the internal array sensor. Imagine. In particular, in order to avoid getting caught in the turbulent flow from the screw of the test vessel 13 when turning into the sea and turning the two tow expanders together, the array sensor group 6 is messed up. At the stern, we carefully feed out the screw, turning the main engine, steering instructions, tail wave and the situation of the sailing ship.

  However, depending on the sea surface condition, the tow expander 2 and the like are pulled up again on the ship, the connecting portion between the composite transmission line cable 1 and the tow expander 2 is separated, and the twist of the composite transmission line and the entanglement of the array sensor group 6 are caused. Sometimes it is understood. In such a case, inspection and confirmation of the optical system and electrical system of the apparatus and external observation are performed, which requires a large number of people and time, and affects the morale of the team.

  Furthermore, in recent years, composite transmission lines employing optical fiber cables have a problem that must be made sensitive to increase in optical transmission loss due to twisting before reaching the kink, and adopt optical fiber cables. For this apparatus, a large number of optical reception sensors are operated, and the influence of loss due to twisting of the cable when transmitting the received weak optical signal is greatly affected. In addition, since the towing expander is tilted, in addition to the loss of optical transmission, the directivity of the tow expander sound source and the array gain of the array sensor group are greatly affected.

  For this purpose, an invention of an apparatus that can quickly detect the twist generated in a composite transmission line or the like and immediately untwist the composite transmission line safely and easily is desired.

    In view of the above, the present invention is a cable drum device that can quickly detect the twisting of the composite transmission line cable and its connecting portion, and can quickly and easily untwist the composite transmission line safely and easily. The purpose is to provide.

  Next, means for solving the above problems will be described with reference to the drawings corresponding to the embodiments.

In the present invention, a cable for winding or rewinding a telemeter transmission line cable 1 for transmitting a signal from an underwater signal sensor (array sensor group 6) provided at the tip to the measurement ship (test ship 13) side on the measurement ship side. In the drum device, a drum axis line is formed between a laterally fixed stationary outer cylinder 15, a rotating inner cylinder 16 rotatably provided on an inner peripheral surface of the stationary outer cylinder 15, and a diametrically opposed inner wall of the rotating inner cylinder 16. A cable drum 37 provided rotatably inside the rotating inner cylinder 16 so as to be set. When the transmission line cable 1 is wound around the cable drum 37, the drum axis of the cable drum 37 is While rotating in the outer peripheral direction, the fixed outer cylinder 15 is tilted forward and backward integrally with the rotating inner cylinder 16 to be tilted.

  The underwater signal sensor has a structure in which a plurality of linearly arranged sensor groups 5 are arranged in parallel and are towed horizontally, and the transmission line cable includes at least an optical transmission line conductor 28 and an energization line conductor. 29 is a composite transmission line cable 1 in which a power transmission line 29 and a power line 30 are combined.

  The cable drum 37 can be rotated forward and backward by the driving force of the drive motor 22.

  A driven gear train 66 is formed at the opening edge of the rotating inner cylinder 16, and the driven gear train 66 meshes with a separately provided drive gear 69, whereby the driven gear 69 rotates forward and backward to drive the driven gear. The rotating inner cylinder 16 is driven to rotate forward and backward via the row 66.

  Further, the present invention uses the cable drum device described above, and marks the light reflecting material in the length direction of the transmission line cable 1 at a required distance (paint color mark (1) 38, paint color mark (2) 39. And output signals of photosensors erected at two locations of the conduction path of the transmission line cable 1 on the measurement ship by the processor 11 of the control room provided in the measurement ship. Twist is detected and calculated, and the transmission line cable 1 is fed out in the appropriate length direction by active control that feeds back the calculation signal to the rotation driving portions of the cable drum 37 and the rotating inner cylinder 16. It is characterized in that it is rotated so as to release the twist.

  Further, the present invention uses the cable drum device described above, from the installation position of the cable drum device installed on the deck of the measurement ship 13 to the required position in the stern direction along the transmission line cable 1. Each sensor of the torsion meter, the wire length meter 58, and the tension meter 57 for the transmission line cable passing length when the cable 1 is unwound / lifted is installed, and these signal outputs are sent to the arithmetic processing unit for calculation. Further, the controller 10 is fed back to control the operation of the cable drum device, and has a feedback circuit that realizes horizontal towing of the array sensor group 6 constituting the underwater signal sensor throughout the measurement time, and performs active control. It is characterized by things.

  In the invention of the present application, in order to eliminate the unnecessary twist occurring in the length direction of the composite transmission line cable of optical / electrical / mechanical connection, the rotation of the cable drum 14 is rotated and fed out of the conventional composite transmission line cable. In addition to the rotation of the direction, a new mechanism structure that tilts and rotates in the axial direction of the composite transmission cable is adopted.

  As shown in FIG. 2, this structure is a vertical rotation type cable drum device in which a fixed outer cylinder 15 having a large diameter and a flat shape with a perpendicular axis of rotation is fixed to a deck 45 of a test ship 13. The cable drum 37 of the composite transmission line is arranged in the rotating inner cylinder 16 and the rotation of the composite transmission line cable 1 in the axial direction and the length direction is performed by individual motors (the cable drum driving motor 22 and the rotating inner cylinder driving motor 31). Each one is driven.

  FIG. 4 showing the stern of the test vessel 15 includes a torsion detector 55, a rotary wire length meter 58, a rotary tension meter 57, and a GPS receiver 9 in the device room 8 of FIG. The output is communicated to the controller 10 by the composite transmission line, and the twist amount and the wire length with respect to the wire length of the composite transmission line cable 1 as well as the tension and ship position can be detected, and this is twisted by the composite transmission line cable 1. An interlocking operation or a manual individual operation is performed by electrically feeding back to the drive system so as not to cause a failure and appropriately controlling the cable drum 14 and the rotating inner cylinder 16.

  In addition, in order to electrically or optically connect between two required portions where one rotates and the other is stationary, a power system conductor 30, a conduction system conductor 29, and a multi-channel optical transmission system conductor In the case of having 28 multiple systems, it is difficult to make a communication connection by using a conventional slip ring.

  Therefore, for the rotating shaft system in the longitudinal direction of the composite transmission line, the “interior-type composite transmission line processing apparatus such as a remote observation device” shown in the above-mentioned Patent Document 1 (Japanese Patent Laid-Open No. 2002-362837) is basically used. By adopting conformity, the fixed drum shaft 36 that passes through the winding drum hollow portion 40 of the cable drum 14 shown in FIG. 3 and rotatably supports the cable drum 14, and the drum shaft 36 in the winding drum hollow portion 40 is used. A driven secondary drum (1) 34 that is rotatably supported integrally with the cable drum 37, and a stationary secondary drum 35 that is fixed to the drum shaft 36 adjacent to the driven secondary drum (1) 34. And a continuous portion of the conductive wire wound or unwound around the driven secondary drum (1) 34 by the swivel 41 of the cable traverser that rotates along the outer circumference of the driven secondary drum and the stationary secondary drum 35. Bridge to 35 Rewind or as wound Te, one rotates, the other is electrically or optically it can be connected by a fixed coupling between predetermined portions of two places to rest.

  Furthermore, as shown in FIG. 2, the transmission line connection of a remote measuring instrument or the like shown in Japanese Patent Publication No. 57-60679 related to the application of the present applicant is shown in FIG. Adopted “apparatus”. That is, under the driven sub-drum (2) 19 attached to the bottom of the central axis of the rotating inner cylinder in the middle of the conductive wire, the side plate 26 of the receiving box-shaped conductive wire reservoir 25 fixed to the deck or the lower part penetrates. It penetrates the hole 27. Thereby, since the margin part of the conducting wire descending from the driven secondary drum (2) 19 is stacked in the conducting wire reservoir 25, it can be communicated.

  Due to the fixed connection between the two departments, there is no brush like a slip ring, so a high-power, high-quality power source can be supplied to the sound generator section of the towing expander shown in FIG. The Further, the echo received by the array sensor group can also be obtained by the multi-channel optical signal through the plurality of optical transmission system conductors 28 without degrading S [signal] / N (noise) by the fixed junction of the optical transmission system. , Sent to the signal processor with high quality and analyzed.

  The towing expander 2 shown in FIG. 1 incorporates a transmitter of the sound source unit 3 to transmit underwater sound in the required direction in the sea and attach and deploy the array sensor group 6 to the wing 4 at a required interval. Considering the subsequent strength and stability, the roll, pitch, inclinometer, azimuth meter, depth meter, tension meter, etc. necessary for the attitude sensor of the tow deployer 2 and the optical transmission line 28 pass through the fuselage. ing. Although the tow expander 2 is more stable with the attachment of various types of fins, the turbulence induced by them is also increased, and the undesired situation in which the array sensor group 6 is placed in the long turbulent flow behind it. In order to avoid this, and in consideration of operational workability, a simple external shape is adopted.

  In addition to the arrangement of the drums and the like described above, the rotary shaft orthogonal type cable drum device is provided with a drive mechanism, a detection mechanism, a lock mechanism, and an interlocking mechanism, and does not require any manual work. The tow deployer and array sensor group can be tested with their original behavior and characteristics without causing damage to the tow expander and sensor group by safely unwinding the twist of the transmission line and the behavior of the composite transmission line cable. . Further, it is possible to provide a rotary shaft orthogonal cable drum device that is effective in improving safety and labor saving.

  The present invention is a rotating shaft orthogonal type cable drum device characterized by having a drive mechanism, a detection mechanism, and a torsional relaxation mechanism structure in addition to the arrangement of each of the drums described above, and is generated in the length direction of the composite transmission line. It is possible to effectively relieve and cancel unnecessary twists and avoid cable kink obstacles, and the two rotation axis concepts of the single cable drum 37 of the vertical rotation type are based on an optical fiber on land. There is an extremely large effect that affects the cost, workability, and reliability, such as cable repair and rewinding work at the same time as normal wires.

  In addition, unnecessary twisting that has occurred in the composite transmission line can be automatically resolved, and conventionally, optical amplification parts in the middle of the cable that have been placed extra in anticipation of optical transmission loss due to kink failure are no longer necessary. Drastically reducing costs.

  In addition, to repair torsional troubles, the tow expander, etc. is pulled up again on the ship, separating and connecting the connection between the composite transmission line and the tow expander, twisting of the composite transmission line, and array sensor group It is possible to avoid the work by all members of the test ship for untangling, inspection and confirmation work of the optical transmission system and power supply system of the equipment, and return to the quay of the cable manufacturing facility, or the request of additional workers is unnecessary. A substantial cost reduction is expected.

  According to the present invention, it can be carried out by the test team, and the test ship crew can concentrate on the original place of the ship, and the safety of the test ship is ensured.

  In addition, there is no need for additional workers, and there are large expenses such as damage to the sensor group when the array sensor group is entangled, repair cost in the case of a kink failure in the composite transmission line, extended usage fee for the test ship, etc. In addition to the significant benefits that can be saved, repair time can be used for testing time, team morale can be maintained, and valuable and reliable data can be acquired that can be provided to advance the technology and converted into expenses. There is an extremely large technical effect that cannot be achieved.

  Furthermore, in the design of the composite transmission line, the torque balance structure for avoiding cable kink failure and the strength of the connection part with the tow expander and the special design adopting a high safety factor were relatively expensive. With the invention of the twist sensor and the rotation mechanism for solving the twist, the cable kink can be sufficiently handled and the composite transmission line manufactured by the normal design can be used sufficiently, so that the cost can be greatly reduced. In addition, since the fear of applying a large load due to cable kink can be eliminated, the weight of the design structure related to the strength structure of the composite transmission line, the tow expander and the array sensor group can be reduced by reviewing the allowable load with a safety factor in anticipation of it. The burden can be reduced and each part can be changed from large to medium and from medium to small. At the same time, fluid resistance is reduced and the flow noise is also greatly reduced, greatly improving the performance of the array sensor group. There is an effect to make.

  A power transmission wire 30 for driving the sound source from underwater to the ship, an energizing cable and a multi-channel optical transmission line 28 are integrally formed with the towing line, and a rotating mechanism that extends the composite transmission line to two axes. By overcoming and connecting with fixed connection, the twist of the composite transmission line is continuously monitored over the whole process from the introduction of the composite transmission line in the sea test to the long-time towing test and unloading. It has become possible to respond quickly to the situation, and it has become possible to stop the great difficulty in a small difficulty.

  In addition, since the communication is performed by fixed coupling, a high-power and high-quality power source can be supplied to the sound source unit of the tow expander, and an acoustic transmission convenient for echo analysis is achieved. Furthermore, the echo received by the array sensor group is also high in the multi-channel optical signal without degrading S [signal] / N (noise) by the fixed junction of the optical transmission system. The quality will be sent to the arithmetic processing unit, which will greatly improve performance.

  In particular, if there are unclear parts in the observation data, the composite transmission line can be extended at any time, allowing the towing speed to be reduced immediately and avoiding the effects of flow noise that increases with the sixth power of the towing speed. Thus, it is possible to make a determination in a condition where the received signal can be emphasized, and the reliability of acquired data is further improved. Furthermore, it is possible to acquire effective observation data and expand the observation area without inefficiency such as re-acquisition of data by re-entering the observation sea level and restarting the observation work. This man-hour reduction effect and the expansion of the observation area have a significant economic effect.

  The best mode for carrying out the present invention will be described below with reference to the accompanying drawings.

An embodiment of the rotation axis orthogonal cable drum apparatus will be described with reference to FIG.
The rotation axis orthogonal cable drum device 14 of this embodiment installed on the deck 45 of the test ship 13 as a measurement ship is a conventional one that unwinds and entrains the composite transmission line cable 1 by rotating it in the feeding or lifting direction. The vertical type single cable drum 37 is basically used. The rotating shaft orthogonal type cable drum device 14 has a fixed outer cylinder 15 having a large diameter and a flat double cylinder held on a deck 45 of a measurement ship so that an opening end face thereof is in the same direction as the delivery of the composite transmission line cable 1. Installation is fixed. End face ridges 44 are formed on the outer periphery of both end faces of the fixed outer cylinder 15. There is a rotating inner cylinder 16 that forms a double cylinder together with the fixed outer cylinder 15, and a rotor such as a roller bearing 42 is provided on the inner peripheral surface of the fixed outer cylinder 15 and the outer peripheral surface of the rotating inner cylinder 16. This is a mechanism for rotating the rotating inner cylinder 16 through this. The deck 45 is provided with an operation panel 65.

  In the rotating inner cylinder 16, the rotation of the driving gear 69 at the rotating shaft end of the rotating inner cylinder driving motor 31 is transmitted to a driven gear train 66 made of a spur gear provided on the entire circumference of one end surface of the rotating inner cylinder 16, and a composite transmission line. It rotates in the axial direction of the cable 1. Further, the cable drum 37 is placed in the rotating inner cylinder 16, and the rotation of the cable drum 37 is a large gear through the chain 21 from the cable drum drive motor 22 installed on the pedestal 24 on the side of the support plate 43 on one end side of the cable drum 37. 20, and the composite transmission line cable 1 is rotated in the unwinding / withdrawing direction.

  The composite transmission line cable 1 shown in FIG. 4 is combined so that the twist and the passage of the required length of the composite transmission line cable 1 can be detected by the photo twist sensor (1) 54 and the photo twist sensor (2) 51. A paint color mark (1) 38 and a paint color mark (2) 39 are provided so that a broken line can be identified for each required length along the length direction on the outer skin of the transmission line cable 1.

  In this case, the outer periphery of the composite transmission line cable 1 is covered with the slip ring mechanism (1) 62 and the sensor base (2) 52, which are equipped with one sensor base (1) 56 and the other slip ring, by each photo twist sensor. The direction position of each broken line is detected, and this signal is sent to the arithmetic processing unit to calculate the relative twist, and if the twist is large, the rotating inner cylinder 16 is released from the twist. The twist can be properly solved by rotating in the direction of.

  Similarly, the number of rotations of the roller is read simultaneously with the point detection of the paint color marks (1) (2) 38 and 39 when the composite transmission line cable 1 passes through the other sensor base (2) 52, The angle change of the twist with respect to the length, the passing speed and the passing length of the composite transmission line are calculated, and appropriate control is performed by the control panel.

  Further, when the composite transmission line cable 1 is wound up and sent out, the contact angle θ and the rotational load meter determined by the rotary load meter 59, the first stern roller 49 and the moving wheel type angular displacement meter 60 provided on both sides thereof. Based on the measured value of the load W of 59, the cable tension of the composite transmission line cable 1 and the wire length are detected by the rotary tension meter 58, and an appropriate cable drum 37 is used so that no kink failure occurs in the composite transmission line cable 1. And active control to electrically feed back the rotation of the rotating inner cylinder 16. In the above case, each sensor and the arithmetic processing unit / controller 10 are communicated with each other by the lead wires (2) 23. The driving wheel type angular displacement meter 60 is elastically pressed against the composite transmission line cable 1 by a coil spring 61. The composite transmission line cable 1 pulled up from the sea is guided by the stern first roller 49 and the stern roller group 48 subsequent thereto. The stern first roller 49 and the stern roller group 48 are covered with a stern sheep 50.

  Further, as shown in FIG. 2 and FIG. 3, in order to be able to connect electrically and optically by fixed coupling, the driven sub drum (1) 34 and the winding hollow portion 40 inside the winding drum of the cable drum 37 are connected. In addition, a stationary sub drum 35 and a cable traverser swirler 41 swirling along the outer periphery thereof are arranged. The supporting portion of the cable drum 37 is provided with the auxiliary motor 17 with the friction plate and the belt 18, and the lead wire (1) 46 is provided therein. A lead-out portion of the conducting wire (1) 46 from the cable drum 37 is guided by a conducting tube 33. Since the structure and operation inside the winding drum of the cable drum 37 are the same as those described in Patent Document 1 (Japanese Patent Laid-Open No. 2002-362837) of the applicant's invention, detailed description thereof is omitted.

  For the rotating system in the axial direction of the composite transmission line cable 1, the middle of the conducting wire is engaged with a secondary auxiliary drum (2) 19 at the bottom of the central axis of the rotating inner cylinder 16, and is arranged below the receiving drum. The side plate 26 of the box-shaped conductor reservoir 25 is penetrated, and the surplus portion of the conductor descending from the driven sub drum (2) 19 is stacked in the conductor reservoir 25 to communicate with each other.

  FIG. 5 shows another embodiment of a rotation axis orthogonal cable drum that can be used as a single-channel optical transmission system, energization system, and power system. This is because an optical slip ring of a single optical transmission system is attached to one end surface of the shaft that rotates integrally with the winding drum, and the electrical continuity between the power system and the current-carrying system is provided on the outer periphery of the shaft. There is a slip ring mechanism (1) 62 to which a slip ring is attached. Similarly, a slip ring mechanism (2) 63 in which an optical slip ring of a single channel optical transmission system and an electrically conductive slip ring of a power system and an energization system are mounted on the bottom of the central shaft in the rotating inner cylinder. Is attached. The slip ring mechanism (2) 63 is supported on the deck by the support column 64.

  According to the above configuration, the vertically placed cable drum 37 is fixedly disposed on the inner peripheral surface of the rotating inner cylinder 16, and the composite transmission line cable 1 is fed into the sea. The composite transmission line cable 1 can be rotated in the axial direction, and the composite transmission line cable 1 that has never existed in the past is continued to be unwound or lifted, and at the same time, the twist of the composite transmission line cable 1 is removed. By rotating it, cable kink failure can be prevented.

  The twist of the composite transmission line cable 1 acts as a force for tilting the tow expander, disturbs the tow attitude of the array sensor group, greatly affects the acoustic performance, and causes a loss in optical transmission. Unnecessary twisting, which is a factor such as, can be removed.

  In addition, a twist photo sensor, a line length meter, a tension meter, and a GPS receiver are arranged so that the output of each sensor communicates with the controller via a conductor, and the twist amount and the line length with respect to the line length of the composite transmission line, and the tension.・ The ship position can be detected. Furthermore, this can be electrically fed back to the motor drive system so that there is no twisting trouble in the composite transmission line, and appropriate rotation drive control can be performed on the cable drum 37 and the rotating inner cylinder 16. The twist of the composite transmission line cable 1 can be released by automatically and manually rotating the biaxial shaft 37.

  In addition, when the tow expander with the array sensor group attached from the stern of the measurement ship is thrown into the sea when it is caught in the turbulent flow from the screw of the measurement ship and the tow expander turns, the array sensor group Check whether the optical transmission etc. is good or not until the end of the array sensor group. It can be rotated and unwound to a predetermined length.

  Despite the fact that the master and the working chief are carefully feeding the stern at the stern while taking into consideration the situation of the ship's turning and stopping of the main engine, steering instruction, tail wave and sailing ship, Depending on the sea level, the tow expander, etc. may be lifted again on the ship, the connection between the composite transmission line and the tow expander may be separated, and the twist of the composite transmission line and the entanglement of the array sensor group may be released, and the optical system of the device It is possible to avoid work that requires many people and time, such as checking and checking the electrical system and external observation. In addition, it is possible to avoid the influence of the team's morale due to repeated complicated and troublesome repair work, and the amount of the time can be used for the test time, and sufficient data can be obtained for the evaluation.

  In addition, since the tow expander can perform stable horizontal towing, the subsequent array sensor group can eliminate the influence of the tilt towing that the tow attitude has been covered by the tilt of the conventional tow expander, and the original array sensor group The acoustic characteristics can be obtained, and the acquired data greatly contributes to the improvement of the design technology.

  In the design of composite transmission lines, the cost is reduced due to the twisting of the cable, that is, the torque balance structure to avoid the cable kink failure, the strength of the connection part with the tow expander and the special design adopting high safety factor Although it tends to be high, the invention of the twist sensor of the present invention and the rotation mechanism for untwisting can sufficiently cope with the cable kink, so that a composite transmission line cable manufactured by a normal design can be used.

  In addition, a stationary sub drum 35, a driven sub drum (1) 34, and a swivel 41 are used between two required portions where one rotates and the other stops, and two electrical or optical connections are made by fixed coupling. Communicated across departments.

  By this fixed coupling, since there is no brush like a slip ring, a high-power, high-quality power source can be supplied to the sound source section of the towing expander, and acoustic transmission convenient for echo analysis can be performed. In addition, the echo received by the array sensor group is high without the deterioration of S [signal] / N (noise) by the multi-channel optical output signal by a plurality of optical transmission lines due to the fixed junction of the optical transmission system. Since the quality is sent to the signal processor, the performance of the observation device is further improved.
