[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] Please see Figures 1-4 A tail fin thruster in this embodiment includes a mounting plate 1 and a tail fin 2 disposed on one side surface of the mounting plate 1. A thruster body 3 is disposed on the surface of the tail fin 2. The thruster body 3 has a built-in drive motor 31 and a driver 32. The surface of the thruster body 3 is provided with one or more drag-reducing surfaces 35. One or more water inlets 36 are opened on the surface of the drag-reducing surfaces 35. A trapezoidal guide platform 37 is integrally disposed on the surface of the thruster body 3 near the rear end. A plurality of water outlets 39 are opened on the peripheral surface of the trapezoidal guide platform 37.

[0026] The head of the propeller body 3 is conical, and the angle formed between the water inlet 36 and the conical head of the propeller body 3 is θ, and 0°<θ≤60°;

[0027] After the tail fin 2 is mounted on the propeller plate via the mounting plate 1, the direction of the propeller plate can be controlled by the tail fin 2, making the movement of the propeller plate directional. The propeller body 3, through its built-in drive motor 31 and driver 32, drives the propeller plate, eliminating the need for manual propulsion and saving effort. Simultaneously, during the propeller plate's movement, the inlet 36 allows water to enter the propeller body 3 and exit through the outlet 39, thus cooling the built-in driver 32 and drive motor 31 and improving their efficiency. The drag-reducing surface 35 guides the water flow and reduces drag, as does the conical head. The angle between the inlet 36 and the conical head increases the water intake of the inlet 36, improving heat dissipation efficiency. The trapezoidal guide platform 37 guides the water under water pressure as the propeller body 3 moves forward, increasing the water flow through the propeller 34, reducing bubble generation, and thus improving propulsion.

[0028] Among them, the drive motor 31 and the driver 32 are electrically connected to an external power supply through wires. The output end of the drive motor 31 is provided with a drive rod 33. The surface of the trapezoidal guide platform 37 is provided with several support frames 5. The surface of the several support frames 5 is equipped with a protective shell 4. The protective shell 4 is provided with a propeller 34. The propeller 34 is connected to the output end 31 of the drive motor through the drive rod 33. The diameter of the drive motor 31 is smaller than the diameter of the propeller 34.

[0029] The drive motor 31 and driver 32 can drive the drive rod 33 under the action of an external power source, so that the propeller can move forward normally. The protective shell 4 can protect the propeller 34 installed inside, thereby preventing the propeller 34 from being damaged by collision with external objects in the water when it is working in the water. The diameter of the drive motor 31 is smaller than the diameter of the propeller 34, which can reduce the water resistance of the propeller body 3 when it is working in the water and improve the utilization rate of the power source.

[0030] The working principle of the above embodiments is as follows:

[0031] In use, the drive motor 31 and the driver 32 can drive the drive rod 33 under the action of an external power source, so that the paddle can move forward normally. At this time, during the forward movement of the paddle, the water inlet 36 can allow water to flow into the propeller body 3 and be discharged from the water outlet 39, thereby cooling the built-in driver 32 and drive motor 31 and improving the working efficiency of the driver 32 and drive motor 31. At the same time, the drag-reducing surface 35 can guide the water and reduce drag, and the conical head also has the effect of reducing drag. The angle between the water inlet 36 and the conical head can increase the water intake effect of the water inlet 36 and improve the heat dissipation efficiency. The trapezoidal guide platform 37 can guide the water under water pressure when the propeller body 3 moves forward, which can increase the water flow through the propeller 34, reduce the generation of air bubbles, and thus improve the propulsion effect.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
