Abstract

PURPOSE:To eliminate high costs due to an amount of a using cable of a suspension cable and reduce an occupied area in a housing box. CONSTITUTION:A rubber cord 1 is tightly wound and aligned into a hollow body like a doughnut. At this time, an air-core normal close winding is formed starting end of the rubber cord being positioned at an inner side of the doughnut. A cable 18 formed by coating a conductor with a coating material is also similarly wound into a tightly wound body. A partition thin plate 19 in the shape of a doughnut penetrates in the vicinity of the starting end of the rubber cord 1 so as to separate the cable 18 and rubber cord 1 to avoid the mixing. The starting end of the rubber cord 1 through the partition plate 19 is sent up through a hollow part of the cable 18 from below and accommodated in a cylindrical case 4 while attached to one end drawn out from inside of the cable 18. When the rubber cord 1 and cable 18 are simultaneously taken out as a marine sensor is thrown into water, the cable is spirally wound in the periphery of the rubber cord 1 to form a curl.

By operating the parachute case 3, the parachute case 9 is separated from the housing case 6.

The storage case 4 is stored in the lower portion of the floating portion 14, and the suspension cable 3 is spirally stored in the storage case 4. Further, in the lower portion of the storage case 4, FIG. As shown in (b), the damper 15 connected to the lower end of the suspension cable 3 and the sensor 16 connected to the end of the cable 2 via the damper 15 are housed.

Next, a description will be given of the expanding operation when the ocean sensor having the above-mentioned configuration is operated. The ocean sensor dropped from an aircraft or a ship descends while the parachute 7 is being extended, as shown in FIG. As shown in the figure, when the water is landed on the water surface, it eventually sinks into the water due to its own weight as shown in FIG. Then, due to this sinking, seawater enters the housing 6 through a hole (not shown) provided in the housing 6, and the seawater battery (not shown) provided in the float expansion mechanism 13 is activated.

When the seawater battery is started, the float expansion mechanism 13 is activated to generate gas or the like and supply it to the float 11 to expand the float 11. This float 1
The expansion force of 1 causes the float cap 12 to move to the connecting plate 10.

Then, it floats above the surface of the water. At this time, since the storage case 4 remains in the storage housing 6, the float 11 floats while the suspension cable 3 connected to the lower surface of the floating portion 14 is fed out from the storage case 4. In addition, since the storage case 6 sinks in water due to its own weight and the weight of the bottom cover 8, FIG.
As shown in (a), the suspension cable 3 is gradually drawn out from the storage case 4 that remains inside the storage housing 6 by the floating force of the float 11 and the sinking force of the storage housing 6.

When the suspension cable 3 is further extended to the storage housing 6 by sinking and the rubber cord 1 of the suspension cable 3 is extended to a predetermined length, the storage case 4 stops sinking. However, since the storage case 6 continues to sink due to its own weight, the storage case 4 is detached from the storage case 6 as shown in FIG. 8B. When the storage case 4 is detached, the damper 1 connected to the storage case 4 via a cable
5 and the sensor 16 are also detached from the housing 6 in order, and as a result, the sensor 16 is suspended at a desired depth below the surface of the water via the suspension cable 3, whereby the expansion operation is completed.

[0013]

However, in the above-described conventional suspension cable structure, the straight portion of the rubber cord is wound so as to cover the entire length thereof by the curl portion of the cable, that is, the curl of the cable. Since the length of the portion is equal to the length L of the straight portion of the rubber cord, there is a problem in that the amount of cables used is large and the cost is high.

Further, the ocean sensor has a structure in which each component, that is, a parachute case, a float, a float expansion mechanism, a suspension cable, a sensor, and the like must be accommodated in a storage housing of a limited size. During this storage, parts other than the suspension cable, such as a sensor, must be upsized or the length of the cable must be increased, which increases the volume occupied in the storage housing, and the storage volume of the suspension cable must be reduced. When such a situation occurs,
Due to the large capacity of the cable, there was a problem that it was not possible to deal with the reduction in the storage capacity.

The present invention has been made to solve the above-mentioned problems, and eliminates the high cost caused by the amount of cables used for the suspension cable, and the storage volume other than the suspension cable in the storage housing is reduced. A method of forming a curl of a suspension cable that facilitates storage in a storage housing even if the number increases and does not impair its function, and a suspension cable for storing the suspension cable thus formed in a storage case. It is intended to provide a storage structure.

[0016]

In order to achieve the above-mentioned object, the present invention firstly describes, as a method for forming a curl of a suspension cable, a linear member having elasticity and insulation and a conductive wire coated with a coating material. When the underwater sensor is suspended at a desired depth by extending a suspension cable composed of the suspension cable into the water from the lower surface of the float floated on the water surface, the linear member is provided to retain the elasticity of the suspension cable. In a method for forming a curl of a suspension cable, which forms a curl that can be spirally covered by the cable around the
An air-core aligned dense winding is formed by aligning and winding the linear member so that the starting end side of the linear member is located inside and the center is hollow and the periphery thereof is surrounded, and the conductive wire is formed. A cable formed by covering with a covering material is formed into an air-core aligned close-wound having a hollow at the same center as the linear member, with its one end facing inside, and the other end is located outside the linear member. A doughnut-shaped partition plate, which is attached to the end and near the start of the linear member, forms a donut shape that separates the cable and the linear member so as not to mix with the air-core aligned densely wound cable. At the same time, the starting end of the linear member penetrating the partition plate is attached to one end of the cable, which is an air-core aligned and densely wound air-core part that penetrates the air-core part from below to above. Housed in a cylindrical shape of the housing case in the state,
As a result, when the ocean sensor is dropped into the water, the starting end side of the rubber cord is extended upward and is expanded into the water. At the same time, the cord attached to the starting end of the rubber cord is also extended from the one end side and spirals around the rubber cord. It is intended to be wound in a shape to form a curl.

Next, as a structure for accommodating the suspension cable in the accommodating case, one end of the cable in which the conductor wire is covered with a covering material is formed on the starting end side of the elastic and insulating linear member, and the other end is formed on the terminal end side. The other end of the cable is attached, and the suspension cable, in which the linear member is spirally surrounded by the cable over the entire length, is detached from the inside of the housing by the drop of the marine sensor and is expanded in the water. In the storage structure of the suspension cable to be stored as described above, the inner peripheral surface is located at a position approximately half the depth of the inner peripheral surface of the bottomed cylindrical storage case having an opening at the top and a through hole at the center of the bottom. A flange portion is formed so as to protrude inward along the storage member, and the linear member is provided on the lower side of the flange portion of the storage case with the starting end side thereof being the inner side. The doughnut-shaped air-core aligned densely wound linear member is wound by aligning and winding so as to surround the periphery with the center as a cavity, and on the upper side of the flange portion of the storage case, A cable is a donut-shaped air-core aligned densely wound cable in which the partition plate is horizontally accommodated and held by the flange portion, and further, the cable has a hollow at the center like the linear member so that one end of the cable is inside. And pulling out the starting end side of the linear member housed in the lower part of the housing case upward and penetrating the central hole of the partition plate and the air core part of the cable housed on the partition plate. And then attached to one end of the cable, and the other end of the cable is guided to the lower side of the storage case from the notch provided in the partition plate and stored in the lower side. Of those which to attach the end.

[0018]

In the above-mentioned structure, when the suspension cable is stored in the storage case and the ocean sensor having the storage case built in the storage case is dropped from an aircraft or a ship, the ocean sensor sinks into the water. On the other hand, the components constituting various marine sensors are fed out from the storage housing.

The suspension cables are also sequentially extended upward from the storage case by these extensions. At this time, as the suspension cable, an air-core aligned densely wound cable is stored on the upper side of a storage case having an open upper surface, and a line member also air-core aligned and densely wound on the lower side is partitioned by a partition plate for storage. However, since the starting end and one end of the cable and the linear member pass through the air cores of each other, and also penetrate the central hole of the partition plate and are pulled out to the upper part of the storage case to be connected to each other, The linear member and the linear member are simultaneously fed out from the storage case into the water.

At this time, since the linear member is fed while penetrating through the air core of the cable, which is aligned with the air core, the cable is spirally wound around the linear member fed into the water. Will be done. That is, the cable is extended into the water while forming a curl that covers the periphery of the linear member. When all the linear members and the cables are fed out from the storage case, the partition plate falls by its own weight so as to be placed on the flange portion inside the storage case. As a result, the suspension cable is composed of a linear member that is linearly expanded in the center and a cable that is curled so as to surround the linear member in a spiral shape and is expanded in water.

[0021]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an external view showing a suspension cable of this embodiment. As shown in FIG. 1, the suspension cable of this embodiment has a length of a cable having a curl portion spirally surrounding a linear member, In the conventional example, the spring constant of the cable is shortened within a range that does not cause a change to reduce the usage amount, and the linear member and the cable are separately air-core aligned and tightly wound, and are stored without curling. It was done like this. In this embodiment, rubber cords and cables as linear members of the suspension cable, a storage case described later for storing the suspension cable, and other components except the partition plate are almost the same as the conventional structure, And since it is constituted similarly, the same numerals are attached here and the explanation is omitted.

In the figure, reference numeral 17 denotes a suspension cable. The suspension cable 17 has a rubber cord 1 as a linear member, a ring-shaped portion 1a provided on the starting end side and the terminal end side of the rubber cord 1, and both end portions 18a thereof. And a cable 18 that binds the suspension cable 17, and when the suspension cable 17 is extended in water, the cable 18 forms a curl having a spring constant that does not change from the spring constant of the curl portion in the conventional example. While trying to get out.

The curl portion 18b forming the coil spring-like curl has two ring-shaped portions 1a provided at both ends of the rubber cord 1 and a stretched portion 1b having a length L between the elastic portions 1a and 1a. When the stretched portion 1b is stretched in water, the entire length of the stretched portion 1b is spirally wound. That is, the rubber cord 1 and the cable 18 are separately stored in the storage case 6 of the ocean sensor, and the curl portion 18b of the cable 18 surrounds the stretched portion 1b of the rubber cord 1 at the same time as the stretching operation in water. It is intended to be wrapped.

2 to FIG. 2, a structure for accommodating the suspension cable 17 having the above-described structure in the accommodating case 4 and a curl forming method for forming a curl on the cable 18 by being drawn out from the accommodating case 4 will be described. 4 will be described. First, FIG. 2 is an explanatory view showing a storage structure of a suspension cable, and FIG.
(B) shows the BB sectional drawing of (a).

As shown in the figure, the storage case 4 is formed in a cylindrical shape having an opening on the upper surface, and a partition surface 4a is provided at a predetermined depth to partition the storage case 4 to store a suspension cable which will be described later. Although the storage portion 4b is formed and the through hole 4c is formed in the center of the partition surface 4a, it is similar to the conventional storage case structure.
In the present embodiment, further, on the inner peripheral surface of the storage portion 4b of the storage case 4, at a position approximately half the depth of the storage portion 4b, and inside the storage portion 4b with a predetermined width along the inner peripheral surface. The protruding flange portion 4d is configured, and the inside of the storage case 4 is divided into two upper and lower chambers on the upper side and the lower side with the flange portion 4d as a boundary.

On the other hand, the rubber cord 1 and the cable 18 in the suspension cable 17 are separately and closely wound in air-core alignment. That is, the center of the rubber cord 1 and the cable 18 is an air core in a hollow state, and the circumference is spirally surrounded and aligned so as to be closely wound, so that the starting end side is pulled out from the inner side of the air core. By doing so, it is possible to unwind easily. When the cable 18 is in the air-core aligned close-wound state, the hollow portion at the center of the cable 18 is in a state in which the linear stretched portion 1a of the rubber cord 1 is penetrated. This is the cable 18 that is formed when the cable 18 is stretched in water.
This is to allow the curl portion 18b to cover the periphery of the rubber cord 1.

Reference numeral 19 denotes the flange portion 4d formed to divide the storage portion 4b of the storage case 4 into upper and lower chambers.
Is a partition plate to be placed on the upper surface side of the storage case, and is formed in a donut shape by a thin plate material, the outer diameter of which is slightly smaller than the inner diameter of the storage case 4, and a cutout is formed in a part of the outer peripheral surface thereof. The portion 19a is provided, and the notch portion 19a guides the end of the air-core aligned close-wound cable 18 to be stored on the upper side in the storage portion 4b of the storage case 4 to the lower side, and the air core stored on the lower side. The tightly wound rubber cord 1 is fixedly attached to the ring-shaped portion 1a at the end thereof.

The rubber cord 1 and the starting end of the cable 18 are pulled out from the air core of the cable 18 and connected to another unit (not shown). After passing through the air-core portion of the cable 18 and further passing through the central hole of the doughnut-shaped partition plate 19 on the flange portion 4d that divides the storage portion 4b of the storage case 4 into upper and lower chambers, the partition plate On the lower side of 19, the air-core is closely packed and stored. The closely-rolled end-side ring-shaped portion 1a is extended downward from a through-hole portion 4c formed in the bottom surface of the storage case 4, and the notch of the partition plate 19 is formed in the ring-shaped portion 1a. Part 19
The end of the cable 18 led out to the lower side of the partition plate 19 from a is fixed, and the suspension cable 17 is connected to a unit (not shown) stored under the storage case 4 and stored. It is stored in the case 4.

Therefore, when the ocean sensor is dropped and the suspension cable 17 is stretched in water, the suspension cable 17 is extended by the unit (not shown) arranged above the storage case 4 and the cable 18 and the rubber cord 1 are extended. And at the same time, the starting end side is pulled so that it can be unwound from the inside of the air-core aligned close-wound state and smoothly drawn upward through the cavity and the hole of the partition plate 19. .

The expansion operation of the suspension cable 17 housed in the storage case 4 as described above will be described with reference to FIGS. 3 and 4 showing the expansion operation when the marine sensor equipped with the storage case 4 is in operation. To do. In FIGS. 3 and 4, the same parts as those of the conventional one are designated by the same reference numerals, and the description thereof will be omitted. Further, the expansion operation of the marine sensor will be the same as the conventional one except for the expansion operation of the suspension cable 17. Since it is almost the same as the above, the description is omitted here to avoid duplication, and the expansion operation of the suspension cable 17 will be mainly described.

When the ocean sensor is dropped from an aircraft or a ship and descends while spreading the parachute as shown in FIG. 3 (a) to land on the water, the storage housing 6 sinks into the water due to its own weight, and the storage housing 6 is stored. Seawater enters the housing 6 to activate the seawater battery. Therefore, the float 11 starts to expand by the float expansion mechanism 13 as shown in FIG. 7B, and the expansion force of the float 11 causes the parachute 7 and the parachute case 9 to be expanded as shown in FIG.
Then, the coupling plate 10 is separated from the storage housing 6 in an integrated state.

As a result, the inflated float 11 is shown in FIG.
As shown in (a), the float expansion mechanism 13 floats inside the storage housing 6, and eventually separates from the storage housing 6 and floats above the water surface. At this time, the float 11 floats while gradually extending the suspension cable 17 connected to the lower surface of the floating portion 14 from the starting end side of the storage case 4. Since the starting end side of the suspension cable 17 is secured to the cable 18 and each starting end side of the rubber cord 1 via the ring-shaped portion 1a of the rubber cord 1, both of them are fed out integrally. That is, the rubber cords 1 arranged above the storage case 4 with the partition plate 19 as a boundary can be unwound from the inside of the air core, and the rubber cords 1 arranged below the holes of the partition plate 19 and The cable 18 is fed through the air core portion so that it can be unwound from the inside of the air core.

At the time of this feeding operation, the rubber cord 1 and the cable 18 are wound in a curled state in a certain direction because the rubber core 1 and the cable 18 are closely wound in a spiral shape, and the rubber cord 1 is fed to the cable 18. On the other hand, since it is short in a predetermined relationship, it is stretched in a straight line in a twisted state, and the cable 18 is extended so that the rubber cord 1 penetrates straight through the center thereof, and as described above. Since the rubber cord 1 is longer than the rubber cord 1 in a predetermined relationship, as shown in FIG. 3B, the rubber cord 1 is fed while curling so as to cover the rubber cord 1 from its periphery. Become.

The feeding force of the suspension cable 17 causes the storage case 6 to settle down as the storage case 6 sinks in water due to its own weight and the weight of the bottom lid 13 in addition to the floating of the float 11. This is because the suspension cable 17 is also paid out by the sinking force of the storage housing 6. Then, as the storage housing 6 further sinks into the water, the suspension cable 17 is gradually extended upward from the upper and lower two chambers of the storage case 4, and the lower portion shorter than the cable 18 stored on the upper side. After all the rubber cords 1 housed on the side have been paid out, the remaining cable 18 which has not been paid out is drawn out into the water while forming a curl so as to be unwound from the air-core aligned close-wound state.

At this time, since the end of the suspension cable 17 is connected to the lower unit (not shown), the rubber cord 1 is stretched linearly as if it is pulled by this lower unit, and at the same time as it is fed out. In the center of the cable 18 that is being extended while forming a curl,
In the direction of the arrow b shown in FIG. 7B, that is, the curl portion 18a is pulled in and expanded.

When all the suspension cables 17 housed in the housing case 4 are thus fed out, the rubber cord 1 is stretched to a predetermined length and stretched, and the cable 18 is curled over the entire length of the stretched portion 1b. It will be spread in the water while being wound by the portion 18b. At this time, the partition plate 19 remains in the storage case 4 due to its own weight and remains in the storage case 4 while remaining on the flange portion 4d.
At the same time, the suspension cable 17 is suspended at the lower end. In the suspension cable 17 shown in FIG. 1, the partition plate 19 exists in a state of penetrating the rubber cord 1, but it is omitted in FIG.

When all of the suspension cables 17 are fed out as described above, the subsidence of the storage case 4 is suspended by the suspension cables 17 and stops. However, the storage case housing the storage case 4 is stopped. Since the body 6 continues to sink in the water due to its own weight,
As shown in (b), the storage case 4 is detached upward from the storage housing 6. As a result, the damper 15, which is connected to the storage case 4 via the cable, and the sensor 16
However, when the sensors 16 are sequentially separated from the inside of the housing case 6 and as a result, the sensor 16 is expanded to the lowermost end at a desired depth below the water surface, the expansion operation ends.

[0038]

As described above, according to the present invention, the wire member and the cable that form the suspension cable are separately air-core aligned and tightly wound, and are partitioned in a cylindrical storage case having an open upper surface. The cable is arranged on the upper side through the plate, the linear member is arranged on the lower side, and the starting end side of the linear member located on the lower side is pulled out from the inside of the linear member and then the central hole of the partition plate. Part, and further, after passing through the air core of the cable on the upper side, it is connected to the starting end side of the cable, and the end of the cable is connected to the end of the linear member on the lower side. When the suspension cable is paid out, the linear member forming the suspension cable and the cable are paid out so that they can be unwound from the inner side of the air-core aligned dense winding, so that Wrapped around the cable helically to form a curl, in which so as to cover over the linear member throughout its length.

Therefore, compared with the conventional suspension cable which has been formed by covering the entire linear member with the curl portion of the cable from the stage before being stored in the storage case, the amount of cable used is greatly reduced. Therefore, it is possible to eliminate the high cost caused by the usage amount of the cable, and to realize a suspension cable that has the same function as the conventional one even at a low cost.

Further, since the volume of the suspension cable is reduced by reducing the usage amount of the cable, when the suspension cable is accommodated together with other components, the occupied volume required for accommodating the suspension cable is reduced. Therefore, when the sensor, which is each of the other constituent parts, is enlarged, or when the length of the cable for suspending the sensor is desired to be increased, the occupied volume for accommodating them can be increased.

The storage case for storing the suspension cable having the above structure has a structure in which a flange portion is provided along the inner peripheral surface at a position at a depth of about a half of a cylindrical shape having an open upper surface, and A partition plate having an outer diameter slightly smaller than the inner diameter of the storage case is placed on the upper surface of the flange portion, and the linear member is stored on the lower side of the storage case and the cable is stored on the upper side through the partition plate. , The lower end of the linear member is pulled out from the inside, and is connected to one end of the cable through the hole in the center of the partition plate and the air core of the densely wound cable, while the end of the cable is cut by the partition plate. The suspension cable is connected to the lower end of the storage case through the notch and is connected to the end of the linear member to store the suspension cable in the storage case.

As a result, when the ocean sensor is dropped into the water and the suspension cable is started to be unwound from the storage case, the suspension cable can be unwound from the inside of the air-core aligned dense winding at the same time as the cable and the linear member. It can be easily and promptly fed upward. Furthermore, since the cable and the linear member are partitioned by the partition plate, it is possible to prevent the cables from being entangled with each other and to smoothly feed the cable and the linear member.

A flange portion is formed so as to project inward along the inner peripheral surface, and the linear member is positioned below the flange portion of the storage case such that the starting end side thereof is inside and the center thereof is a cavity. The doughnut-shaped air-core aligned densely wound linear member is housed by arranging and winding so as to surround the periphery, and the partition plate is horizontally provided by the flange portion above the flange portion of the storage case. In addition, the cable is housed and held in the same manner as the linear member, and the cable is housed in a donut-shaped air-core aligned close-wound cable having a hollow center like the linear member. The starting end side of the linear member housed in the lower side is pulled out upward, and the hole in the center of the partition plate and the air core part of the cable housed on the partition plate are penetrated, and then the case The cable is attached to one end of the cable, and the other end of the cable is guided from the notch provided in the partition plate to the lower side of the storage case and attached to the end of the linear member stored in the lower side.
