Description

Technical Field

[0001] The utility model belongs to the technical field of propellers, and particularly relates to a propeller device. Background Art

[0002] A propeller is a device that converts any form of energy into mechanical energy. It generates thrust by rotating blades or jets (water). It can be used to drive a vehicle forward or as a power source for other devices such as generators.

[0003] Traditional propellers have problems such as high noise and low transmission efficiency. After long-term use, the blades may be corroded. In addition, there is a possibility of damage caused by impact from foreign objects, which requires replacement of the blades. Most of the existing propellers are integral structures, so when replacing the blades, they need to be replaced as a whole, resulting in a waste of resources.

[0004] To this end, we provide a thruster device to solve the above-mentioned problems. Utility Model Content

[0005] The utility model aims to provide a propeller device, which solves the existing problem of requiring the overall replacement of the propeller by designing the propeller blades to be detachable.

[0006] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] The utility model is a propeller device, comprising a fixing component, including a housing, a stator winding arranged inside the housing, a rotor ring arranged inside the stator winding, and a blade fixing ring arranged inside the rotor ring;

[0008] The disassembly and assembly component comprises a blade assembly arranged inside the housing; the blade assembly comprises a rotating blade fixed inside the blade fixing ring, a fairing arranged on the inner side of the rotating blade, and a rotating shaft penetrating inside the fairing; wherein the rotating blade is fixedly connected to the blade fixing ring;

[0009] A clamping assembly is arranged inside the blade assembly; the clamping assembly comprises a clamping sleeve arranged inside the rotating blade, a push rod passing through the clamping sleeve, a cross bar fixed to one side of the push rod, a guide sleeve sleeved on the outer wall of the push rod, and a clamping block arranged at the top end of the push rod;

[0010] And a driving assembly arranged inside the clamping assembly; the driving assembly includes a fixed shaft arranged inside the clamping sleeve, a rotating gear sleeved on the outer wall of the fixed shaft, a through groove running through the rotating gear, a connecting rod fixed to the top side of the clamping sleeve, a motor arranged at the end of the connecting rod, and a transmission gear fixed to the driving end of the motor.

[0011] The utility model is further configured such that the guide sleeve is evenly fixed inside the clamping sleeve, the guide sleeve is slidably connected to the inner wall of the push rod, the fixed shaft is fixedly connected to the clamping sleeve, the fixed shaft is rotationally connected to the rotating gear, and the rotating gear is meshed with the transmission gear.

[0012] The utility model is further configured that the disassembly and assembly component also includes a connection assembly fixed in the blade assembly, and the connection assembly includes a fixing collar arranged inside the deflector, a fixing groove opened inside the fixing collar, and a limit block arranged inside the fixing groove;

[0013] Wherein, the limiting block is fixedly connected to the fixing groove.

[0014] The utility model is further configured to also include a rotating assembly, including a connecting sleeve that passes through the deflector cover, a deflector shell sleeved on the outer wall of the rotating shaft, a gear ring arranged on one side of the deflector shell, a carrier frame sleeved on the outer wall of the rotating shaft, a connecting gear arranged on the carrier frame, and a driving gear arranged on the inner side of the connecting gear.

[0015] The utility model is further configured such that the connecting sleeve is rotatably connected to the rotating shaft and is fixedly connected to the air deflector on the rear side, the air deflector shell is fixedly connected to the connecting sleeve and is rotatably connected to the rotating shaft, the air deflector shell is fixedly connected to the gear ring, and the supporting frame is fixedly connected to the rotating shaft.

[0017] The utility model has the following beneficial effects:

[0018] 1. In the utility model, the motor serves as the driving source of the transmission gear. When the motor is started, it drives the transmission gear to rotate. When the transmission gear rotates, it drives the rotating gear meshing with it to rotate. When the rotating gear rotates, the angle of the through slot set on the rotating gear changes, that is, the height of the two ends changes. Since the cross bar is restricted and can only move up and down, when the rotating gear rotates, it causes the cross bar to move up and down, thereby realizing the up and down movement of the clamping block, further realizing that the clamping block can be clamped into or out of the fixed slot, indirectly achieving the purpose of disassembling and replacing the rotating blades.

[0019] 2. The utility model drives the driving gear to rotate by rotating the rotating shaft, and also rotates the guide shell through the meshing action between the gear ring, the connecting gear and the driving gear. The guide shell is fixedly connected to the rear guide cover through a connecting sleeve. This design enables the two-part rotating blades to achieve forward and reverse rotation, forming a counter-rotating propulsion water flow movement, and its transmission efficiency is higher than that of a single propeller.

[0020] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
