Description

Technical Field

[0001] The utility model belongs to the technical field of ship propellers, and in particular relates to a hydraulic lifting type electric full-rotation propeller. Background Art

[0002] A ship propeller refers to an energy converter in a ship's propulsion device, which converts the power generated by the engine into thrust for the ship to move forward, in order to overcome the resistance of the ship sailing in the water and drive the ship forward. The most common propeller is a propeller, in addition there are paddle wheels, water jets, jet propulsion, ducted propulsion, and transverse propulsion, etc. However, since some ship types have a large aspect ratio and are difficult to turn in narrow waterways, a side thruster is installed at the bow. When the ship is unloaded, the bow position cannot guarantee full draft, and ordinary side thrusters cannot meet the use requirements. In addition, ordinary side thrusters mostly use gear meshing transmission. Since the gears are corroded and rusted due to long-term contact with water, the meshing is locked. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0022] Example 1

[0023] like Figure 1 As shown;

[0024] The hydraulic lifting electric full-rotation thruster comprises a pair of L-shaped supports 1 and a top plate 2 arranged on the top of the two L-shaped supports 1.

[0025] In this embodiment: In order to solve the technical problems existing in this prior art, as disclosed in the background technology above, "due to the large length-to-width ratio of some ship types, it is difficult to turn in narrow waterways, so a side thruster is installed at the bow, and when the ship is unloaded, the bow position cannot ensure complete draft, and ordinary side thrusters cannot meet the use requirements. In addition, ordinary side thrusters mostly use gear meshing transmission. Since the gears are in contact with water for a long time, they will corrode and rust, resulting in meshing lock." Combined with actual use, this problem is obviously a real problem that exists and is relatively difficult to solve. In view of this, in order to solve this technical problem, a lifting component 3 is added on this basis.

[0026] like Figure 1-Figure 4 As shown;

[0027] In combination with the above content, in order to meet the draft requirements of the thruster and prevent the pushing mechanism from being rusted and locked, it also includes a lifting assembly 3 arranged at the front end of the two L-shaped supports 1;

[0028] The lifting assembly 3 includes a pair of support blocks 31 fixed at the front ends of the two L-shaped supports 1 and a lifting hydraulic cylinder 32 fixed at the top of the top plate 2. A limiting slide groove 33 is provided on the inner wall of the support block 31. A U-shaped lubricating oil chamber 39 is provided inside the support block 31. An oil inlet 34 is fixed on the top of the support block 31, and the oil inlet 34 is connected to the U-shaped lubricating oil chamber 39.

[0029] In an optional embodiment, a plurality of slots 35 are provided on the support block 31 between the U-shaped lubricating oil chamber 39 and the limiting slide groove 33, and a circularly rotating steel ball 36 is clamped inside the slot 35. The U-shaped lubricating oil chamber 39 and the limiting slide groove 33 are connected through the slot 35, and the two ends of the steel ball 36 extend into the U-shaped lubricating oil chamber 39 and the limiting slide groove 33 respectively.

[0030] In this implementation scheme: the I-shaped slider 37 slides up and down inside the limiting slide groove 33, driving the steel ball 36 to rotate in a circle inside the slot 35, and then the two ends of the steel ball 36 reciprocate inside the U-shaped lubricating oil chamber 39 and the limiting slide groove 33, and then the steel ball 36 is lubricated, so that the I-shaped slider 37 and the steel ball 36 are always lubricated to prevent long-term water corrosion and cause the linkage effect to be locked.

[0031] In an optional embodiment, an I-shaped slider 37 is provided inside the limiting slide groove 33 between the two rows of steel balls 36, and a full-return thruster 38 is provided between the two I-shaped sliders 37. The I-shaped slider 37 is placed inside the limiting slide groove 33, and the two are not in contact with each other. The grooves on the left and right ends of the I-shaped slider 37 match the steel balls 36, and the I-shaped slider 37 is limited by the steel balls 36. The lower end of the telescopic rod of the lifting hydraulic cylinder 32 is fixedly connected to the top center of the full-return thruster 38.

[0032] In this embodiment: the lifting hydraulic cylinder 32 pushes the full-return thruster 38 to move downward, and the full-return thruster 38 drives the I-shaped slider 37 to slide up and down inside the limiting slide groove 33, so that the full-return thruster 38 meets the draft requirement.

[0033] The working principle of the utility model is as follows: the lifting hydraulic cylinder 32 pushes the full-return propeller 38 to move downward, and the full-return propeller 38 drives the I-shaped slider 37 to slide up and down inside the limiting slide groove 33, so that the full-return propeller 38 meets the draft requirement, and the I-shaped slider 37 slides up and down inside the limiting slide groove 33, driving the steel ball 36 to rotate in a circle inside the card slot 35, so that the two ends of the steel ball 36 reciprocate inside the U-shaped lubricating oil chamber 39 and the limiting slide groove 33, and then the steel ball 36 is lubricated, so that the I-shaped slider 37 and the steel ball 36 are always kept in a lubricated state to prevent long-term water corrosion and cause the linkage effect to be locked.

[0034] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the present invention.
