Description

Technical Field

[0001] The utility model relates to the technical field of propeller shells, in particular to a quick-installable propeller shell. Background Art

[0002] A propeller is a rotating mechanical device used to propel an aircraft or a ship forward. It generates a propulsive force to move the aircraft or ship. A propeller usually consists of blades, a hub, and blade connections. The key part of the propeller, usually made of composite materials or metals, has an aerodynamic design to maximize the propulsion efficiency. A propeller is also the main propulsion method for most ships. By rotating the propeller blades in water, the hull is pushed forward. Usually, a shell is added outside. The shell can enhance the structural strength of the propeller, especially under high-speed rotation and high load, and can withstand various forces and pressures during navigation. It can prevent the propeller from being damaged or deformed due to air flow, flutter, or other external forces.

[0003] Traditional propeller shells are usually made of lightweight composite materials or metals to ensure strength and light weight. The design of the shell aims to reduce the resistance in air flow, especially during driving, which can effectively reduce the aerodynamic resistance and effectively protect the propeller blades and hub from the external environment.

[0004] However, traditional propeller shells are usually directly welded around the propeller. Since the shell is directly welded around the propeller, when subsequent maintenance or replacement of the propeller is required, more time and labor may be needed, which will affect the availability and maintenance efficiency of the ship. Therefore, a quick-installable propeller shell is proposed to solve the above problems. Summary of the Utility Model

DETAILED DESCRIPTION

[0030] 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.

[0031] Reference Figure 1 and Figure 2, an embodiment provided by the present utility model: a quick - install propeller housing, including a protective housing 1. A limiting hole 6 is provided inside the protective housing 1, a slide rail 10 is provided inside the protective housing 1, a limiting groove 7 is provided on the protective housing 1, a thruster 13 is provided inside the protective housing 1. A starting device 2 is fixedly connected to the top of the thruster 13, the outer wall of the starting device 2 is slidably connected inside the slide rail 10. On the outer wall of the thruster 13, a fixture 9 is provided, a slider 8 is slidably connected inside the fixture 9, the outer wall of the slider 8 is slidably connected inside the limiting groove 7. A fixing block 14 is fixedly connected to the bottom of the thruster 13, a positive and negative thread lead screw 4 is threadedly connected inside the fixing block 14, the outer wall of the positive and negative thread lead screw 4 is rotatably connected inside the limiting hole 6, and starting components are provided at both ends of the positive and negative thread lead screw 4, and the starting components act on the rotation of the positive and negative thread lead screw 4.

[0032] Specifically, the protective housing 1 is sleeved on the outer wall of the thruster 13, and then the positive and negative thread lead screw 4 is rotated. By driving the fixing block 14 to move through the positive and negative thread lead screw 4, and then driving the fixture 9 to move through the fixing block 14, the thruster 13 is fixed, so that the housing can be installed conveniently. Quickly installing the housing can significantly reduce the assembly time, which is very important for the production line efficiency and the overall manufacturing cost of the ship. At the same time, when the propeller 11 needs to be maintained or replaced, the quickly installed housing design can greatly simplify this process. Through simple operations, technicians can quickly remove the old protective housing 1 and install a new protective housing 1, thereby reducing the maintenance time and the labor intensity of the staff. Thus, installing the protective housing 1 can reduce the safety risks that may be caused by the exposure or damage of the propeller blades.

[0033] Refer to Figure 2 , the starting components include hexagonal holes 5, and the outer walls of the hexagonal holes 5 are provided at both ends inside the positive and negative thread lead screw 4.

[0034] Specifically, the hexagonal holes 5 can conveniently rotate the positive and negative thread lead screw 4. The hexagonal holes 5 provide a more stable and reliable connection, and can withstand higher torsional forces without sliding or damage easily.

[0035] Refer to Figure 1 and Figure 3, a propeller 11 is provided inside the thruster 13. A fixed rod 12 is fixedly connected inside the thruster 13. A fluid guide 15 is fixedly connected to the outer wall of the fixed rod 12. A fixing groove 17 is formed inside the protective housing 1. A rotating block 16 is rotatably connected to the outer wall of the fixing groove 17. A fixing plate 18 is fixedly connected to the outer wall of the rotating block 16. A through hole 21 is formed inside the fixing plate 18. A rotating column 20 is provided inside the through hole 21. A rotating block 19 is fixedly connected to the top of the rotating column 20. The outer wall of the rotating block 19 is slidably connected inside the through hole 21. The outer wall of the rotating column 20 is slidably connected inside the through hole 21. The bottom of the rotating column 20 is rotatably connected to a filter screen 3. The outer wall of the filter screen 3 is slidably connected inside the filter screen 3.

[0036] Specifically, rotate the rotating block 19. Through the rotation of the rotating block 19, the fixing plate 18 rotates, so that the filter screen 3 can be conveniently replaced and fixed. By effectively filtering the impurities in seawater through the filter screen 3, the damage and wear of the blades and the hub can be reduced, which can extend the service life of the propeller 11, reduce the maintenance period and cost, reduce the impact of blade damage and replacement on the environment, and at the same time reduce the energy consumption of the ship. At the same time, preventing external objects from entering the inside of the propeller 11 can not only protect the ship, but also improve the operation safety of the crew and reduce the risk of accidents.

[0037] Working principle: Drive the protective housing 1 with the slide rail 10 formed inside it into the outer wall of the starting device 2 with internal sliding connection. Then, drive the external left - and - right - hand threaded screw rod 4 to rotate inside the limiting hole 6 where it is rotatably connected through the hexagonal hole 5. Then, drive the fixed block 14 connected by thread through the left - and - right - hand threaded screw rod 4 to move. Subsequently, drive the fixture 9 fixedly connected by the fixed block 14 to move. Then, drive the slider 8 slidably connected inside the fixture 9 to move inside the limiting groove 7 where it is slidably connected, so as to fix the thruster 13 inside the protective housing 1, playing a protective role for the thruster and preventing damage to it caused by sundries in seawater. Then, place the filter screen 3 into the protective housing 1 with sliding connection. Rotate the fixing plate 18 to the outer wall of the rotatable column 20 with sliding connection. Then, rotate the rotating block 19 and fix it through the rotating block 19, so as to fix the filter screen 3 inside the protective housing 1 and filter the seawater. After that, the starting device 2 can be turned on. Drive the propeller 11 fixedly connected inside the starting device 2 to rotate, thereby driving the ship to move.
