[0002] The bow thruster is a special propeller installed at the bow of a ship to improve the maneuverability of the ship.

[0003] Most of the existing bow thrusters are straight tube propeller type thrusters, including propellers, drive mechanisms, straight section pipe tunnel bodies, and straight tube cover structures. The propeller is installed in the straight section pipe tunnel body, and straight tube cover structures are provided at both ends of the straight section pipe tunnel body. The drive mechanism drives the propeller to rotate in the straight section pipe tunnel body, thereby generating thrust. Since the bottom of wide-body ships such as special exploration ships is U-shaped, wide-body ships have the characteristics of shallow draft, which leads to the existing straight tube propeller type thrusters easily leaking out of the water under the action of wind and waves, making the thrusters ineffective. Utility Model Content

[0004] The utility model provides a side thruster for a wide-body ship, so as to solve the technical problem that the existing straight tube propeller type side thruster is easily affected by wind and waves and leaks out of the water when used for the wide-body ship, causing the side thruster to lose its function.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] A side thruster for a wide-body ship, combined with Figure 1 and Figure 2 As shown, it includes a port thruster unit and a starboard thruster unit. The port thruster unit includes: a port propeller 11, a port drive mechanism 12 and a port cylinder 13; the output end of the port drive mechanism 12 is connected to the port propeller 11 by transmission, one end of the port cylinder 13 is arranged on the port side of the wide-body ship 3, and the other end is arranged on the bottom of the wide-body ship 3, and the port propeller 11 is arranged in the port cylinder 13. The starboard thruster unit includes: a starboard propeller 21, a starboard drive mechanism 22 and a starboard cylinder 23; the output end of the starboard drive mechanism 22 is connected to the starboard propeller 21 by transmission, one end of the starboard cylinder 23 is arranged on the starboard side of the wide-body ship 3, and the other end is arranged on the bottom of the wide-body ship 3, and the starboard propeller 21 is arranged in the starboard cylinder 23. The thrust device utilizes the characteristic that the wide-body ship 3 has good stability despite its shallow draft. By arranging one end of the port cylinder 13 on the port side of the wide-body ship 3 and the other end on the bottom of the wide-body ship 3, and arranging one end of the starboard cylinder 23 on the starboard side of the wide-body ship 3 and the other end on the bottom of the wide-body ship 3, it is ensured that one end of the port cylinder 13 and the starboard cylinder 23 are always located below the water surface, so that water can always flow into the port cylinder 13 and the starboard cylinder 23; thereby ensuring that the port thrust unit and the starboard thrust unit can normally take in water under wind and wave conditions, avoiding the port propeller 11 and the starboard propeller 21 from idling and being unable to push water out of the port side ports, and ensuring that the thrust device can work normally.

[0024] Compared with the existing thruster device which needs two straight sections of tunnel bodies to meet the thrust of the port and starboard sides of the wide-body ship 3, the thruster device of the present invention is provided with a port thruster unit and a starboard thruster unit to replace two parallel thrusters, thereby reducing the volume of the thruster device, saving installation space, and facilitating the layout of the internal cabin of the wide-body ship 3. In addition, the length of the thruster device is reduced, and the path through which water flows is shortened, thereby reducing the resistance of water flow, thereby increasing the generated thrust.

[0025] Preferably, the port side cylinder 13 includes a first port side cylinder 131 and a second port side cylinder 132 connected in sequence, one end of the first port side cylinder 131 is arranged on the port side of the wide-body ship 3, and one end of the second port side cylinder 132 is arranged on the bottom of the wide-body ship 3. The axis of the first port side cylinder 131 is arranged parallel to the base plane of the wide-body ship 3 to ensure that the ejected water is along the base plane direction of the wide-body ship 3, avoiding the existence of an inclination angle to weaken the thrust generated by the thrust device. The axis of the second port side cylinder 132 is arranged to be tilted downward, so that one end of the second port side cylinder 132 can be arranged on the bottom of the wide-body ship 3. The port side propeller 11 is arranged in the first port side cylinder 131, and the port side propeller 11 rotates under the drive of the port side drive mechanism 12, thereby pushing water to be ejected outward along the axis of the first port side cylinder 131 to generate thrust.

[0026] Preferably, the angle between the axis of the second port side cylinder 132 and the base plane of the wide-body ship 3 is 30°, which reduces the flow resistance of water in the port side cylinder 13 and ensures that the water at the bottom of the wide-body ship 3 can be smoothly pumped into the port side cylinder 13.

[0027] Preferably, the first port side cylinder 131 is provided at the port side of the wide-body ship 3 and is provided with a bell mouth 133 extending outwardly. The bell mouth 133 is connected to the hull steel plate of the wide-body ship 3 and the connection is smoothed, which can effectively reduce the resistance caused by turbulence and cavitation.

[0028] Preferably, the starboard cylinder 23 includes a first starboard cylinder 231 and a second starboard cylinder 232 connected in sequence, one end of the first starboard cylinder 231 is arranged at the starboard side of the wide-body ship 3, and one end of the second starboard cylinder 232 is arranged at the bottom of the wide-body ship 3, the axis of the first starboard cylinder 231 is arranged parallel to the base plane of the wide-body ship 3, the axis of the second starboard cylinder 232 is arranged downwardly inclined, and the starboard propeller 21 is arranged in the first starboard cylinder 231. The first starboard cylinder 231 and the second starboard cylinder 232 can ensure that the starboard thrust unit can normally generate thrust.

[0029] Specifically, the angle between the axis of the second starboard cylinder 232 and the base plane of the wide-body ship 3 is 30°, which reduces the flow resistance of water in the starboard cylinder 23 and ensures that the water at the bottom of the wide-body ship 3 can be smoothly pumped into the starboard cylinder 23. When the port propeller 11 rotates forward to generate lateral thrust, the horizontal component of thrust generated by the starboard propeller 21 reverses and is in the same direction as the lateral thrust generated by the port propeller 11, and jointly pushes the wide-body ship 3. Conversely, when the starboard propeller 21 rotates forward to generate lateral thrust, the port propeller 11 reverses and can also generate thrust to cooperate in pushing the wide-body ship 3.

[0030] Specifically, the first starboard cylinder 231 is provided at the starboard port of the wide-body ship 3 and is provided with a bell mouth 133 extending outwardly to reduce the resistance caused by turbulence and cavitation at the port position.

[0031] Preferably, the port thrust unit and the starboard thrust unit are symmetrically arranged, that is, the first port cylinder 131 and the first starboard cylinder 231 are coaxially arranged, so that the thrusts generated by the port thrust unit and the starboard thrust unit are in opposite directions and the action point is located on the axis of the first port cylinder 131. At the same time, it is convenient for the ship to control the thrusts on both sides of the ship.

[0032] Preferably, a first grille cover is provided in the port of the port side cylinder 13 disposed at the bottom of the wide-body ship 3, and a second grille cover is provided in the port of the starboard side cylinder 23 disposed at the bottom of the wide-body ship 3. The first grille cover and the second grille cover can block garbage, stones, water plants, etc., and protect the port side propeller 11 and the starboard side propeller 21 from collision and entanglement with foreign objects.
