Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of ships, in particular to a propulsion auxiliary device for ships. Background Art
[0002] At present, the ship driving and control in the existing technology is basically driven by the combination of propeller + steering gear. When the ship needs to accelerate on the water, it only needs to increase the propeller power to increase the propulsion. The propeller structure and rudder structure in the existing technology are connected to the engine through a huge shaft system and a speed transmission system. The mechanical structure is complex, and it is difficult to eliminate the resistance in front of the ship and the excessive swing of the hull during operation. At present, the existing propeller system can only provide two-dimensional drive, forward and backward, and cannot achieve 360-degree rotation in place, and cannot achieve left and right parallel movement of the hull, which makes it difficult for the ship to leave the shore. When the ship is docked, it can only rely on manual traction; when the ship is off the shore, it needs to be manually pushed away.
[0003] Therefore, it is urgent to propose a propulsion auxiliary device for ships with simple structure and reliable propulsion. Utility Model Content

[0034] like Figures 1 to 4As shown, this embodiment provides a propulsion auxiliary device for a ship, which is installed in the hull of the ship. When the propeller and the steering gear stop running, the propulsion auxiliary device of the ship is used to propel the ship to perform operations such as 360-degree rotation in place, docking, and leaving the shore. Specifically, the propulsion auxiliary device includes a first propulsion assembly and a second propulsion assembly arranged in the hull along the length direction of the hull, a third propulsion assembly and a fourth propulsion assembly arranged in the hull along the width direction of the hull, and a controller connected to the first propulsion assembly, the second propulsion assembly, the third propulsion assembly, and the fourth propulsion assembly. Among them, the third propulsion assembly is vertically connected to the first propulsion assembly and the second propulsion assembly, and the fourth propulsion assembly is vertically connected to the first propulsion assembly and the second propulsion assembly. The first propulsion assembly, the second propulsion assembly, the third propulsion assembly, and the fourth propulsion assembly are placed on the same horizontal plane. In this embodiment, the controller and the propeller are existing mature products, which will not be repeated here.
[0035] In this embodiment, the first propulsion assembly is arranged in parallel with the second propulsion assembly, and the first propulsion assembly includes a first longitudinal propulsion assembly 2, a first two-way two-position electric valve group 13, a first longitudinal connecting pipe 11, a third two-way two-position electric valve group 15 and a third longitudinal propulsion assembly 7, which are sequentially connected from front to back. In addition, the second propulsion assembly includes a second longitudinal propulsion assembly 3, a second two-way two-position electric valve group 14, a second longitudinal connecting pipe 12, a fourth two-way two-position electric valve group 16 and a fourth longitudinal propulsion assembly 8, which are sequentially connected from front to back.
[0036] In this embodiment, in order to obtain lateral movement of the hull, a third propulsion assembly and a fourth propulsion assembly are respectively arranged at the bow and the stern. Among them, the third propulsion assembly includes a first lateral propulsion assembly 1, a first lateral connecting pipe 9 and a second lateral propulsion assembly 4 arranged in sequence from left to right. In the lateral direction (i.e., the hull width direction), the first lateral propulsion assembly 1, the first two-way two-position electric valve group 13, the first lateral connecting pipe 9, and the second lateral propulsion assembly 4 are connected in sequence. In addition, the fourth propulsion assembly includes a third lateral propulsion assembly 5, a second lateral connecting pipe 10 and a fourth lateral propulsion assembly 6 arranged in sequence from left to right. In the lateral direction, the third lateral propulsion assembly 5, the third two-way two-position electric valve group 15, the second lateral connecting pipe 10, the fourth two-way two-position electric valve group 16 and the fourth lateral propulsion assembly 6 are connected in sequence.
[0037] In this embodiment, the first transverse propulsion assembly 1, the first longitudinal propulsion assembly 2, the second longitudinal propulsion assembly 3, the second transverse propulsion assembly 4, the third transverse propulsion assembly 5, and the fourth transverse propulsion assembly 6 have the same structure. Taking the second transverse propulsion assembly 4 as an example, it includes a first pipeline 41, a propeller 42 arranged in the first pipeline 41, a curved pipe portion 43 with one end connected to one end of the first pipeline 41 and inclined downward, and a filter screen 44 connected to the other end of the curved pipe portion 43. Among them, a propeller 42 is arranged in the third longitudinal propulsion assembly 7 and the fourth longitudinal propulsion assembly 8. In this embodiment, the propeller 42, the first two-way two-position electric valve group 13, the second two-way two-position electric valve group 14, the third two-way two-position electric valve group 15, and the fourth two-way two-position electric valve group 16 are electrically connected to the controller.
[0038] In this embodiment, the second two-way, two-position electric valve group 14 includes a valve body 141 with four interfaces, and a motor arranged on the valve body 141; the four interfaces of the valve body 141 are respectively connected to the first transverse connecting pipe 9, the second longitudinal propulsion assembly 3, the second transverse propulsion assembly 4 and the second longitudinal connecting pipe 12.
[0039] When in use, when it is necessary to travel straight along the length direction of the hull, in the first propulsion assembly: the first two-way two-position electric valve group 13 is switched to connect the first longitudinal propulsion assembly 2 with the first longitudinal connecting pipe 11, and the third two-way two-position electric valve group 15 is switched to connect the first longitudinal connecting pipe 11 with the third longitudinal propulsion assembly 7. Similarly, the second propulsion assembly adopts the same connection method. Then, the first longitudinal propulsion assembly 2, the third longitudinal propulsion assembly 7, the second longitudinal propulsion assembly 3, and the fourth longitudinal propulsion assembly 8 are used to propel the hull forward.
[0040] When the hull needs to be propulsed transversely, the first two-way two-position electric valve group 13, the second two-way two-position electric valve group 14, the third two-way two-position electric valve group 15, and the fourth two-way two-position electric valve group 16 are used to switch to the first transverse propulsion component 1, the first two-way two-position electric valve group 13, the first transverse connecting pipe 9, and the second transverse propulsion component 4 are connected, and the third transverse propulsion component 5, the third two-way two-position electric valve group 15, the second transverse connecting pipe 10, the fourth two-way two-position electric valve group 16 and the fourth transverse propulsion component 6 are connected. For example, when it is necessary to move transversely to the right, the first transverse propulsion component 1 and the third transverse propulsion component 5 are started, and the second transverse propulsion component 4 and the fourth transverse propulsion component 6 are stopped; similarly, when it is necessary to move transversely to the left, the second transverse propulsion component 4 and the fourth transverse propulsion component 6 are started, and the first transverse propulsion component 1 and the third transverse propulsion component 5 are stopped.
[0041] The above embodiments are only preferred embodiments of the present utility model and are not intended to limit the protection scope of the present utility model. Any changes that adopt the design principles of the present utility model and are made through non-creative labor on this basis should fall within the protection scope of the present utility model.
