Description of the Related Art In general, a cable for supplying power to a crane, a seabed exploration machine, and other various moving equipment is wound in multiple layers and multiple rows on a cable reel, but conventionally, as shown in FIG. It is aligned and closely wound on a simple cylindrical body 3. That is, in each layer of the cable 1 wound in multiple layers and multiple rows around the trunk 3, adjacent ones are closely wound and aligned. When a cable is wound in multiple layers and multiple rows on a cable reel, unless the cables 1 are aligned and tightly wound as described above, the winding of the cable 1 in the cable reel 2 may be broken and may not be able to be pulled out from the cable reel 2. And tightly wound as described above. In the figure, reference numeral 4 denotes a flange plate of the cable reel 2. The entirety of the cable reel 2 around which the power supply cable 1 is wound is referred to as a power supply cable reel device 5.

い。However, when the power supply cable reel device 5 for mobile equipment described above is used in a state where the cable 1 is completely extended, the mobile equipment cannot be moved farther than that. Therefore, the cable 1 is always used in a state where it is left unwound in the cable reel 2. Therefore, the current is supplied while a part of the cable 1 is left unwound, but the amount of unwound is not always small, and depending on the situation, the current is often supplied in a multilayer winding state.

However, there is a problem that it is difficult to radiate the generated Joule heat, and the cable temperature particularly at the center of the winding (in the vicinity indicated by arrow A in FIG. 3) increases. In other words, in the aligned and densely wound state, the heat generated in the cable 1 at the central portion of the winding is escaping through the cable 1 wound inside and outside thereof, but the efficiency of such heat dissipation is very poor and the cable 1 has a very low efficiency. Since the temperature rises, the current value (allowable current value) that can flow through the cable 1 becomes extremely small depending on the number of rows and the number of layers. The ratio (current reduction rate) of the allowable current of one cable (in a single state) to the allowable current of the multilayer winding (current reduction rate) is, for example, 0.5 (50% ),
When the number of rows is nine or more in a three-layer winding, a low value such as 0.3 (30%) is obtained.

いる。However, when the above-mentioned large-sized cable is used, the cable is further increased in size and weight, and there is a disadvantage that the handling property is deteriorated. In addition, the above-described countermeasures for spraying the cooling water are effective when the unwound cable is very small, but not effective when energized in a multilayer winding state. That is, as shown in the schematic cross-sectional view of FIG. 4 and the partial cutaway view of FIG. 5, adjacent ones of the cables 1 in each layer are in close contact (the close contact portions are indicated by arrows P and Q in FIG. 5). ) Since there is no gap between them, the cooling water does not easily enter the inner layer.
Although the cable 1 enters into the gap between the flange plate 4 of the cable reel 2 and the cable 1 to some extent, it does not easily penetrate to the center of the trunk width, so that the effect of cooling the cable 1 in the central portion of the winding whose temperature has increased is small. Note that the arrow P in FIG. 5 corresponds to the contact portion between the cables 1 in the second layer, and the arrow Q corresponds to the third portion.
It is a contact portion between the cables 1 in the layer. In FIG. 5, the cable 1 of the first layer is indicated as 1A, the cable 1 of the second layer is indicated as 1B, and the cable 1 of the third layer is indicated as 1C.

This will be described with reference to FIG. FIG. 1 shows a power supply cable reel device 15 for a mobile device according to an embodiment of the present invention, in which a cable 1 for feeding power to a mobile device is wound around a cable reel 12 in multiple layers. Although not shown, the power supply cable reel device 15 cools the cable 1 by spraying a cooling liquid on the outer periphery of the cable reel device 15 in order to prevent a rise in cable temperature due to energization. The cable reel 12 of the present invention has a helical groove 13a with a helical pitch P larger than the cable diameter dimension d on the outer periphery of the trunk portion 13.
Then, first, the first layer cable 1 (1A) is spirally wound around the trunk 13 along the spiral groove 13a. As a result, a gap H is provided between adjacent cables (A). Next, the second layer cable 1 (1B) is spirally wound on the first layer 1A at the same pitch as the spiral pitch P, and the third layer cable 1 (1B) is wound on the second layer 1B.

低温水、低温海水等の冷却水を散布する。When power is supplied to a mobile device such as a seafloor using the power supply cable reel device 15 as described above, the cable 1 is used in a state of being left unwound in the cable reel 12 as described above. Although power is supplied when a part of the cable 1 is unwound on the reel 12, power is often supplied when the unwound cable is in a multilayer winding state. In this case, the Joule heat generated in the cable 1 due to energization becomes difficult to radiate, and the cable temperature rises particularly at the winding center. Therefore, if necessary, cooling water such as low-temperature water or low-temperature seawater is sprayed from above the power supply cable reel device 15 to the outer periphery of the cable winding.

を防止できる。The gap H overlapping portion (21) between the two vertically adjacent layers (between the n-th layer and the (n + 1) -th layer)
Although there is a slight difference in the gap shape due to the difference in the winding diameter of each layer, geometrically, the overlapping portion (21) of the gap H between any two layers has substantially the same position and the same position. It occurs in the form of a gap. Therefore, geometrically, the overlapping portion (21) of the gap H substantially matches (the position and the shape of the gap match) in the entire multilayer / multi-row wound cable, and the cooling water passage 21 extends from the outermost layer to the innermost layer of the cable. Communicate directly in the radial direction. Note that, in actual reel winding, various errors are accumulated, which is different from the principle winding mode. However, at least the overlapping portion (2
It is certain that 1) will occur, and since it communicates with the overlapping portion (21) of the upper and lower gaps H through the gap H in the same layer, the cooling water passage 21 that always communicates from the outermost layer to the innermost layer is formed. You. Therefore, even when the temperature of the central part of the winding of the multilayer wound cable rises, the cooling water sprayed on the outer periphery of the cable winding reaches the inner layer through the cooling water passage 21 and is applied to the cable surface of each layer and each row. The heat of the cable is removed by touching, and the heat of the cable is efficiently radiated to the outside. Therefore, a high cooling effect is obtained, and it is possible to prevent the allowable current value that can be passed through the cable 1 from decreasing.

If the cables 1 are not aligned and wound closely, there is a possibility that the windings of the cables 1 may be broken and cannot be pulled out from the cable reel 2. In the present invention, the innermost cable 1 is accommodated in the spiral groove 13 a of the cable reel 12. As described above, the cable 1 in each layer on the outer layer is inserted into the valley between adjacent cables 1 in the layer on the inner layer (not at all points but at two places per one round, as described above). Since the cable 1 is wound after being inserted, the winding of the cable 1 is stabilized also in each of the outer layers, and therefore, the problem of the cable winding collapse does not occur.

A gap is provided between adjacent cables by helically winding at a helical pitch along, and all outer layers are helically wound at the same helical pitch as described above to provide a gap between adjacent cables to form a multilayer.・
Since the cable is wound in multiple rows, this multilayer / multi-row wound cable has an overlapping portion between two vertically adjacent cable gaps, and the gap overlapping portion forms a cooling water passage communicating between the cable layers. It is formed. Therefore, even when the cable winding on the reel is energized when the remaining winding of the cable is in a multilayer winding state and the cable temperature at the center of the winding rises, if the cooling water is sprayed on the outer periphery of the cable winding, the cooling water passes through the cooling water passage. To the inner layer, and the cables in each layer and each row are cooled efficiently, so that it is possible to prevent the allowable current value of the cable from being reduced due to the rise in cable temperature. ), And the cable does not become large and heavy.
