The first guide wheel 141, which is rotated by the auxiliary motor 12, drives the cable to move upward, thereby pulling the cable upward, and tensioning and straightening the cable between the cable-arranging assist 1 and the underwater winch 2.
The frame 3 is located the submerged buoy, and submerged buoy top sets up the opening, arranges and to hold up assistor 1 and this opening adjacently, and when winch 2 was put down the cable under water, the cable upwards was passed through and is held up and hold up assistor 1 after, further leaves the submerged buoy through the opening, enters into the water outside the submerged buoy, and the paying out of cable makes satellite communication buoy can come up to the surface of water to carry out satellite communication, upload the data that submerged buoy gathered.
In the process of the cable laying of the underwater winch 2, the cable arranging auxiliary device 1 continuously pulls the cable upwards through the auxiliary motor 12 and the guide wheel assembly 14, so that the cable before leaving the submerged buoy is kept tight, the cable is prevented from drifting to the other side of the rotary drum 21 of the underwater winch 2 due to looseness, further, the cable is prevented from being reversely wound on the drum 21, further, the satellite communication buoy is prevented from being pulled downwards to a deeper position by the reversely wound cable, the cable on the drum is prevented from being reversely wound to be excessively thick, the cable is prevented from being worn or even broken due to contact of the reversely wound cable and the cable arranging device, smooth floating of the satellite communication buoy is ensured, the stability of the satellite communication function of the submerged buoy is maintained, and the cable structure is ensured to be intact.
When the underwater winch 2 is retracted, the cable enters the submerged buoy through the opening, further passes through the cable-arranging auxiliary device 1 and then is wound on the roller 21 of the underwater winch 2, and the satellite communication buoy is pulled down and submerged under the water by retracting the cable, so that the navigation of the water-surface ship is prevented from being influenced.
In the process of winding the underwater winch 2, the cable winding auxiliary device 1 continuously pulls the cable upwards through the auxiliary motor 12 and the guide wheel assembly 14, so that the cable enters the submerged buoy and is kept tight before being wound on the roller 21, and the cable winding auxiliary device 22 of the underwater winch 2 can stably drive the cable to axially move, so that the cable is wound on the roller 21 layer by layer, the cable is tightly arranged, the cable is prevented from being broken due to disordered mutual extrusion, the cable structure is ensured to be intact, and the cable can be stretched out more in a penetrating way when the cable is released again.
In the above-mentioned exemplary embodiment, the device of supplementary winch row cable has row and is held the assistor, through the guide pulley subassembly under the auxiliary motor drive, the cable of continuously upwards pulling, the cable of paying out or retrieving keeps tightly, guarantee the row of winch under water and hold the ware and can twine the cable layer by layer on the cylinder, avoid the cable to twine the whole external diameter that the messy leads to, thereby prevent the wearing and tearing that cable and row hold up the ware contact and lead to even break, keep tightly when cable receive and release, can also prevent that the cable from twining on the cylinder in opposite directions, guarantee that the cable can be smooth to pay out or withdraw, and then guarantee that the come-up that satellite communication buoy can be smooth to the surface of water, maintain the stability of submerged buoy communication connection, the problem that the cable can't come-up to the surface of water, the cable is easy to tear down that the cable is caused easily to lead to the cable reverse winding is easily caused to the row of current winch is held to hold up.
In addition, the cable passes through the in-process of arranging and taking the assistor, needs to wear to establish first wire seat and second wire seat, and two lead the wire seat and lead the cable, make the cable pass through between two guide pulleys of guide pulley subassembly, guarantee the guide pulley subassembly to the drive effect of cable.
In some embodiments, the wheel diameter of first idler 141 is greater than the wheel diameter of second idler 142. The first guide wheel 141 is connected with an output shaft of the auxiliary motor 12, and serves as a driving wheel for providing driving force for the movement of the cable; the second guide wheel 142 is used as a driven wheel, rotates along with the movement of the cable, is mainly used for pressing the cable, ensures full contact between the cable and the first guide wheel 141, and can stably drive the cable by the first guide wheel 141 to avoid slipping of the first guide wheel 141. The small wheel diameter reduces the rotational inertia of the second guide wheel 142, ensures that the second guide wheel 142 smoothly rotates, and further, can avoid the second guide wheel 142 from forming a large rotational speed difference with the first guide wheel 141 when the second guide wheel 142 rotates from a static state due to large rotational inertia, so that slipping occurs between the second guide wheel 142 and a cable, and the cable abrasion caused by slipping is prevented.
In some embodiments, as shown in fig. 2, the thickness of the second guide pulley 142 is smaller than the width of the groove on the first guide pulley 141, and the outer edge of the second guide pulley 142 is inserted into the groove of the first guide pulley 141 to limit the cable in the groove of the first guide pulley 141. The two guide wheels are mutually spliced, so that the cable is prevented from falling out of the wheel groove, and the first guide wheel 141 can be ensured to be stably driven by the cable. In addition, the second guide wheel 142 is inserted into the first guide wheel 141, so that the wheel surface of the second guide wheel 142 is in contact with the wheel groove of the first guide wheel 141, the first guide wheel 141 not only drives the cable to move and tightens the cable, but also can directly drive the second guide wheel 142 to rotate, the first guide wheel 141 and the second guide wheel 142 are kept to synchronously rotate, and the situation that the second guide wheel 142 wears the cable due to the fact that a large rotating speed difference is formed between the two guide wheels is avoided, so that the cable is ensured to be intact.
In some embodiments, the first wire guide 131 and the second wire guide 132 are vertically aligned to vertically arrange the cable therebetween, and the first guide wheel 141 and the second guide wheel 142 are located at left and right sides of the cable. The cable is vertical through arranging and to be held in the palm and hold up ware 1, prevents that the cable from taking place to crookedly because of gravity, avoids the cable to leave behind the guide pulley subassembly 14, loses the cable side direction removal of pulling the effect, leads to the cable to pile up in first wire seat 131 below, guarantees that the cable passes through behind the guide pulley subassembly 14, can straight line upwards, and smooth and easy leaving is held in the palm and hold up ware 1, guarantees that the operation of blowing is smooth and easy.
In some embodiments, the mounting seat 11 has an adjusting frame 15, the adjusting frame 15 is slidably mounted in a sliding groove 16 formed in the mounting seat 11 through bolts, the adjusting frame 15 is fixed on the mounting seat 11 by tightening the bolts, and the second guide wheel 142 is mounted on the adjusting frame 15. The adjusting frame 15 can be moved along the sliding groove 16 by loosening the bolts, and the distance between the second guide wheel 142 and the first guide wheel 141 is adjusted, so that the cable clamping force is adjusted.
In some embodiments, the first wire guide 131 and the second wire guide 132 are identical in structure, and each has a base 133 and a guide roller assembly 134 mounted in the base 133.
