Description

Technical Field

[0001] This utility model belongs to the field of electric propulsion technology, specifically a side-mounted electric propulsion device. Background Technology

[0002] Side-mounted electric propulsion units are a common type of electric device. Their working principle is primarily based on the electromagnetic induction principle of an electric motor. When current flows through the coils inside the motor, a magnetic field is generated, driving the rotor to rotate. As the rotor rotates, the propulsion blades generate forward thrust, thus achieving propulsion. They are characterized by high efficiency, environmental friendliness, and flexibility. The conversion of electrical energy into mechanical energy is highly efficient, with no emissions and no harm to the environment. Furthermore, their flexible operation adapts to various complex environments, making them widely used in various fields such as electric vehicles, aerospace, and shipbuilding, providing these fields with efficient and environmentally friendly power solutions. The most common application is in ship propulsion.

[0003] When existing side-mounted electric propellers are running in water, the propellers on the side-mounted electric propellers rotate around the shaft. During this rotation, they are very likely to get entangled in aquatic plants. At this time, the side-mounted electric propellers need to be stopped and the aquatic plants cut before the device can run normally again, thus affecting the working efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a side-mounted electric propeller that drives the blades to reciprocate and cut by rotating the second shaft, which solves the problem of the propeller getting tangled in weeds without stopping the machine and improves the waterproof effect.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A side-mounted electric propeller is provided, comprising a propeller body, the propeller body including a housing, a cutting mechanism mounted on the surface of the housing, the cutting mechanism including a first rotating shaft, one end of the first rotating shaft being movably connected to the surface of the housing, a reciprocating groove being formed on the surface of the first rotating shaft, a first gear being fixedly connected to the surface of the first rotating shaft, a movable disk being movably connected to the surface of the reciprocating groove, the movable disk being located to the left of the first gear, a blade holder being fixedly connected to the left side surface of the movable disk, and a blade being fixedly connected to the left side surface of the blade holder.

[0006] Optionally, the surface of the housing is provided with a through hole, and a rotating mechanism is installed on the inner wall of the through hole. The rotating mechanism includes a second rotating shaft, the surface of the second rotating shaft is movably connected to the inner wall of the through hole, and a second gear is fixedly connected to the surface of the second rotating shaft. The end of the second gear meshes with the end of the first gear.

[0007] Optionally, a connecting shell is fixedly connected to the left side surface of the outer shell, a cover is fixedly connected to the inner wall of the connecting shell, the cover is located on the right side of the moving disk, a connecting pin is fixedly connected to the inner wall of the moving disk, and the connecting pin is located inside the reciprocating groove.

[0008] Optionally, a propulsion mechanism is installed on the inner wall of the housing. The propulsion mechanism includes a stator core, the surface of which is fixedly connected to the inner wall of the housing, and a stator winding is fixedly connected to the lower surface of the stator core. A rotor core is installed on the surface of the second shaft, and a rotor winding is fixedly connected to the surface of the rotor core.

[0009] Optionally, a propeller is fixedly connected to the surface of the second shaft, and a sealing mechanism is installed at the end of the second shaft. The sealing mechanism includes a shaft seat, which is installed at the end of the second shaft.

[0010] Optionally, a fixing plate is installed on the inner wall of the outer casing, and a protrusion is fixedly connected to the surface of the fixing plate. A groove is formed on the surface of the outer casing, and the protrusion is installed inside the groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention features a second rotating shaft, a movable disc, and blades. In operation, the second rotating shaft rotates, driving the propeller to rotate and propel it forward. The first rotating shaft, movably connected to the outer casing, rotates under the meshing of a first gear and a second gear. The movable disc, mounted on the surface of the first rotating shaft, is driven to move back and forth in a reciprocating groove via a connecting pin. If the propeller surface is entangled with aquatic plants, the reciprocating movement of the movable disc causes the blades to move back and forth on both sides of the propeller, cutting the plants. This invention solves the problem of propellers becoming entangled with aquatic plants by rotating the second rotating shaft, eliminating the need to stop the machine and thus improving work efficiency.

[0014] This utility model is equipped with a fixed plate, a sealing block, and a sealing ring. In use, the fixed plate is fixed on the right side surface of the shaft seat. During installation, the fixed plate is inserted into the inside of the outer shell from the right side, so that the protrusion fixed on the surface of the fixed plate is placed into the first groove opened in the outer shell. Then, the sealing block is placed on the right side surface of the fixed plate. Finally, when the sealing cover is screwed onto the surface of the outer shell, the sealing ring fixed on the inner wall of the sealing cover is also pressed against the surface of the sealing block, thereby improving the waterproof effect.
