Detailed description of the invention
Referring to figs. 1 through Fig. 5, the utility model screw propeller embodiment is described further.
A kind of screw propeller, comprise blade 2 and wheel hub 3, blade 2 is two or more, and blade 2 is evenly arranged on the outside face of wheel hub 3, and the one side backward of blade 2 is for helical surface or be similar to helical surface, more easily can promote hull and advance.
Wheel hub 3 is generally cylindrical, screw propeller can be made to be subject to less resistance when rotating, wheel hub 3 is provided with at least two suspension ring 5, suspension ring 5 are evenly arranged along the circumferencial direction of wheel hub 3 side, in each suspension ring 5, put on lifting rope just to transport screw propeller, in transport process, the combination of many lifting ropes is stressed compared to single lifting rope more balanced, wherein each root lifting rope can be analyzed to the second pulling force vertical direction pointing on first pulling force of offsetting screw propeller gravity and horizontal direction wheel hub 3 center shaft to the pulling force that screw propeller produces, because the second pulling force points to the cental axial position of wheel hub 3, therefore it can limit screw propeller rocking in the horizontal direction effectively, and many lifting ropes are with the use of screw propeller being distributed the tension uniform of lifting rope, thus reduce the stressed of single lifting rope, increase the service life of lifting rope, the outside face of wheel hub 3 is also provided with the groove 4 for placing suspension ring 5, suspension ring 5 are provided with jointed shaft 6, suspension ring 5 are side walls hinged by jointed shaft 6 and groove 4, suspension ring 5 are selectively accommodated in groove 4, when needs use suspension ring 5, easily suspension ring 5 can be taken out in groove 4 by hinged, when without the need to using suspension ring 5, can suspension ring 5 be accommodated in groove 4, thus prevent the transmission effect affecting screw propeller.
Suspension ring 5 are provided with fixed mechanism, when groove 4 accommodated by suspension ring 5, suspension ring 5 and wheel hub 3 are fixed by fixed mechanism, fixed mechanism can make suspension ring 5 be fixed when closing, prevent screw propeller suspension ring 5 in rotary course from can open voluntarily, increase the resistance rotated, fixed mechanism comprises adapter plate 7, adapter plate 7 is fixedly connected with one end of suspension ring 5, fixed mechanism also comprises fastener 10, fastener 10 is preferably bolt, bolt have be convenient to fastening, dismounting, difficult drop-off, the obvious advantage of fixed effect, the screw rod of bolt is provided with screw thread, adapter plate 7 is provided with the first fixed orifice 8, the screw thread corresponding with screw flight is provided with in first fixed orifice 8, wheel hub 3 is provided with the second fixed orifice 9, the screw thread corresponding with screw flight is provided with in second fixed orifice 9, fastener 10 is arranged in the first fixed orifice 8 and the second fixed orifice 9, first fixed orifice 8 and the second fixed orifice 9 are fixed by fastener 10, when needs use suspension ring 5, back out the bolt be arranged on adapter plate 7, then suspension ring 5 are taken out from groove 4, then on suspension ring 5 are in-built lifting rope to facilitate the transport of screw propeller, lifting rope is taken off after carrying terminates, suspension ring 5 can be closed again, suspension ring 5 fixed by bolt of finally screwing on, the resistance that screw propeller is subject to when rotating is less, wheel hub 3 is provided with the hold down groove 11 for placing adapter plate 7, second fixed orifice 9 is positioned at the bottom surface of hold down groove 11, when suspension ring 5 are closed, adapter plate 7 can be mounted in hold down groove 11, prevent adapter plate 7 from giving prominence to, thus reduce the resistance of screw propeller in the middle of rotary course, suspension ring 5 are provided with the grooving 1 for blocking lifting rope away from one end of jointed shaft 6, when lifting rope is through suspension ring 5, the position of lifting rope can be fixed by grooving 1 effectively, prevent it from offseting, thus rocking of reducing further to produce in transport process.
The above is only preferred implementation of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
