Definitions

  • the present invention relates generally to a propelling system, and more particularly, to a marine propelling system for a boat.
  • a conventional propelling system 10 for a large boat 1 is composed of an open-type propeller 12 and a rudder plate 14. Rotation of the propeller 12 and yaw of the rudder plate 14 can drive the boat 1 to move forward and to turn respectively.
  • the rudder plate 14 is located behind the propeller 12, such that the rudder plate 14 having a predetermined size inevitably counteracts the thrust generated by the propeller 12.
  • the loss of vortex flow generated by the open-type propeller 12 can lessen the propulsive efficiency of such kind of the boat 1.
  • the steering of the boat 1 needs a large yaw angle to allow the boat 1 to effectively turn leftward or rightward due to the shape of the rudder plate 14, such that such kind of the boat 1 is worse in steering maneuverability.
  • a conventional propelling system 20 for a speedboat 2 is also composed of a propeller 22 and a rudder plate 24 located behind the propeller 22.
  • propelling system 20 includes another recited hereinafter.
  • a sideward impeller 26 is mounted to a front section of the hull of the speedboat 2.
  • such sideward impeller 26 not only increases the production cost of the speedboat 2 but decreases the utilization rate of the space inside the hull of the speedboat 2.
  • each of the propellers 12 and 22 and the rudder plates 14 and 24 of the aforesaid two propelling systems 10 and 20 is located at the bottom of the large boat 1 or the speedboat 2, such that objects in the water, like plastic bag, fishing net, or waterweed, may be sucked into the vortex flow to damage the propeller 12 (22); or the propellers 12 and 22 and the rudder plates 14 and 24 may hurt divers or swimmers or marine creatures, like cowfish.
  • the aforesaid large boat and the speedboat only fit the shipping lane of relatively deep water. The last but not the least, they both do not have any means for dexterously controlling backward navigation.
  • the primary objective of the present invention is to provide a marine propelling system, which can greatly enhance the steering maneuverability and the safety of a boat.
  • the marine propelling system composed of a guide shell, a propelling member, a vortex guide member, and a horizontally steering ring.
  • the guide shell includes a guideway for guiding a water flow to pass therethrough.
  • the propelling member includes a main body and a propeller.
  • the main has a plurality of fixed wings located inside a front section thereof for swirling the water flow flowing therein from the guideway in a direction.
  • the propeller is mounted to rear sides of the fixed wings and rotated in a direction converse to that of the water flow passing through the fixed wings.
  • the vortex guide member is made of a flexible material and mounted to an outlet of the main body, extending backward.
  • the horizontally steering ring is sleeved onto a peripheral edge of a front section of the vortex guide member and pivoted to the main body at a top edge thereof and a bottom edge thereof for linking-up with and forcing the vortex guide member to turn leftward or rightward relative to the propelling member.
  • a high-speed vortex flow ejected through the propeller can dexterously drive the boat to turn for better steering maneuverability.
  • the propelling system of the present invention comprises a vertically steering ring sleeved onto the vortex guide member and pivoted to the horizontally steering ring in such a way that the vortex guide member can be linking-up with the vertically steering ring to turn upward or downward so as to properly adjust depress and elevation angles of marine voyage, thus allowing the boat to navigate forward under the least resistance.
  • the propelling system of the present invention comprises an inverted guide hood pivoted to the main body of the propelling member.
  • the inverted guide hood When the boat navigates forward, the inverted guide hood is located above the main body.
  • the inverted guide hood can be displaced to a rear side of the vortex guide member; meanwhile, the vortex flow flowing backward through the propeller is guided by the inverted guide hood to be ejected forward.
  • the vortex guide member can be controlled to turn leftward or rightward to eject the vortex flow toward a left front or right front side. In this way, the boat can still be controlled to turn leftward or rightward while navigating backward.
  • a marine propelling system for a boat 3 in accordance with a preferred embodiment of the present invention is composed of a guide shell 32, an incoming-stream chassis 35, a propelling member 40, a vortex guide member 50, a horizontally steering ring 60, a vertically steering ring 70, and an inverted guide hood 80.
  • the guide shell 32 is mounted to a bottom side of a stem 31 of the boat 3 and includes a streamline guideway 33 for guiding a water flow to pass therethrough.
  • the incoming-stream chassis 35 includes an incoming-stream lower member 36, an incoming-stream grating 37, and an incoming-stream front member 38 for preventing the boat from sucking the trash, floating wood, plastic bag, fishing net or waterweed to further prevent something like propeller from entwinement with the aforesaid things.
  • the propelling member 40 includes a main body 41 and a propeller 42.
  • the main body 41 has a housing 43, a support axial tube 44, four fixed wings 45, a pair of water-baffling wings 46, and a stabilizing wing 47.
  • the housing 43 is fixed to the stem 31 by screws (not shown).
  • the support axial tube 44 is fixed to a center of the housing 43, defining a passage 442 for a water flow to pass through.
  • the fixed wings 45 are fixed to an external surface of the support axial tube 44 and arranged like a cross.
  • the water-baffling wings 46 are mounted to an external surface of the housing 43 and located at two opposite sides (left and right) of the housing 43 for preventing the water flow from impacting an upper side of the propelling member 40.
  • the stabilizing wing 47 is also mounted to the external surface of the housing 43 and located at a bottom side of the housing 43 for keeping the boat 3 in stable navigation.
  • the propeller 42 includes a rotary shaft 422 and a plurality of blades 424.
  • the rotary shaft 422 has a front end inserted into the boat 3 and connected with a power source (not shown), such as an engine or electric motor, and passes through the support axial tube 44, and has a rear end fixedly connected with the blades 424.
  • the vortex guide member 50 is made of a flexible material, such as rubber or the like, and can be forced to pivotably wag.
  • the vortex guide member 50 is combined into the housing 43 of the main body 41 of the propelling member 40 by screws (not shown), extending backward from an outlet end of the housing 43.
  • the horizontally steering ring 60 is sleeved onto a peripheral edge of a front section of the vortex guide member 50, having a top edge and a bottom edge, both of which are pivoted to the housing 43.
  • the horizontally steering ring 60 can be driven by a first driving device 62 to turn leftward or rightward relative to the propelling member 40, and meanwhile, the vortex guide member 50 can be forced to wag leftward or rightward relative to the propelling member 40 to further control the steering of the boat 3.
  • the vertically steering ring 70 is sleeved onto a peripheral edge of a rear section of the vortex guide member 50, having two sides (left and right) pivoted to the horizontally steering ring 60, and can be driven by a second driving device 72 to turn upward or downward, such that the water flow passing through the vortex guide member 50 can be ejected upward or downward.
  • a second driving device 72 to turn upward or downward, such that the water flow passing through the vortex guide member 50 can be ejected upward or downward.
  • the depress and elevation angles of the marine voyage of the boat 3 can be manipulated to keep the boat 3 navigating under the least resistance.
  • the inverted guide hood 80 is pivoted to the main body 41 by a strut 82 and can be driven by a third driving device 86 to shift between a first position P1 and a second position P2.
  • the inverted guide hood 80 While in the first position P1, the inverted guide hood 80 is located behind the propelling member 40, as shown in FIG. 13 , and meanwhile, a vortex flow generated by the propeller 42 is guided by the inverted guide hood 80 to flow forward instead of backward, such that the boat 3 can stop forward navigation or navigate backward.
  • the inverted guide hood 80 is located above the propelling member 40, as shown in FIG.
  • the inverted guide hood 80 includes two guide portions 84 facing forward and inclined slightly downward, as shown in FIG. 4 , and the inverted guide hood 80 has a cross-shaped deflector 88 formed at an internal periphery thereof.
  • the guide portions 84 and the cross-shaped deflector 88 can change backward water flow of the vortex flow ejected to the left, right, and lower sides of the inverted guide hood 80 to forward water flow.
  • the cross-shaped deflector 88 can distribute the water flow in proportion to allow the boat 3 to turn left or right for leftward or rightward navigation, while it navigates backward, to greatly enhance the dexterity of the backward navigation of the boat 3.
  • the first driving device 62 can drive the horizontally steering ring 60 to turn leftward or rightward; meanwhile, the flexible vortex guide member 50 can be linking-up to turn leftward or rightward to enable the vortex flow passing through the vortex guide member 50 to be ejected toward the left rear or right rear side of the boat 3, such that the boat 3 can be controlled to navigate leftward or rightward.
