It can be understood that when the scientific investigation ship needs to perform a small-load towing operation (i.e. the weight of the scientific investigation instrument connected to the lower end of the cable is light, so that the tensile force applied to the cable is obviously small), the friction force between the cable and the stern roller 3 is insufficient, so that the stern roller 3 cannot roll, and the cable directly generates sliding friction with the stern roller 3 in the towing process, so that the cable is easy to wear and break. In the technical scheme of the embodiment, a small load roller 11 which is horizontally arranged can be additionally arranged above the sealing panel 2, and the diameter of the small load roller 11 is smaller than that of the stern roller 3, so that even if the lower end of a mooring rope is subjected to small tension in the towing process, the mooring rope can easily drive the stern roller 3 to roll to form rolling friction, thereby maintaining the rolling support on the mooring rope and preventing the mooring rope from being worn. In short, when the small-load towing operation is required, the horizontal roller 3 can be set to be in a storage state, and then the small-load roller 11 is directly arranged above the closed panel 2, so that the normal operation of the small-load towing operation is ensured, the small-load towing operation is required, and the use is more flexible.
In one embodiment, as shown in fig. 16 to 20, the device further comprises a base 22, the base 22 can be detachably mounted on the top of the closing panel 2, a bracket 23 is fixed on the base 22, two ends of the small load roller 11 are rotatably mounted on the bracket 23 through bearings respectively, in addition, a first limit roller 24 and a second limit roller 25 which extend vertically are mounted on the bracket 23 respectively, the first limit roller 24 and the second limit roller 25 are respectively abutted to the left end and the right end of the small load roller 11, and the first limit roller 24 and the second limit roller 25 are respectively corresponding to the length range of the small load roller 11.
It will be appreciated that since the base 22 is removably mounted on top of the closure panel 2, the mounting and removal of the small load drum 11 over the closure panel 2 can be facilitated, i.e. the small load drum 11 can be removably mounted on the closure panel 2 with the base 22, while the bracket 23 can provide a support and mounting for the small load drum 11. In addition, when the cable is lapped on the surface of the small load roller 11 and is in a moving state, the first limit roller 24 and the second limit roller 25 can limit the transverse movement range of the cable, so that the cable is prevented from being separated from the surface of the small load roller 11 due to transverse deflection in the moving process, in other words, when the cable contacts the first limit roller 24 or the second limit roller 25 due to transverse deflection in the moving process of the surface of the small load roller 11, the first limit roller 24 or the second limit roller 25 can limit the cable to continuously move outwards to prevent the cable from being separated, and simultaneously can synchronously roll and rub with the cable, so that smooth dragging of the cable is ensured.
In one embodiment, the base 22 is fixedly attached to the closure panel 2 by bolts, so that it can be easily removed and installed.
Alternatively, as shown in fig. 16 to 20, the number of the small load drums 11 is two, the two small load drums 11 are vertically arranged on the bracket 23, and the small load drum 11 on the upper side can be disassembled on the bracket 23, so that rolling support can be realized for a plurality of cables at the same time, and the small load drum 11 on the upper side can be disassembled and assembled at will according to the requirement of the offshore operation mode, and single-shaft cable supporting or double-shaft cable supporting can be realized selectively, so that the use is more flexible.
In one embodiment, the weight of the stern roller 3 may be chosen to be greater than or equal to six tons, while the weight of the small-load roller 11 may be chosen to be 0.5 tons, due to its high load demand.
The present embodiment also provides a scientific investigation ship, which comprises a hull 100, wherein a stern working mechanism of the ship according to the present embodiment is arranged at a stern of the hull 100.
