Some embodiments of this application are described in detail. The following embodiments and features of the embodiments may be combined with each other without conflict.

Example

Referring to FIG. 1 , this embodiment provides a propeller 100 including a frame 10 , a motor 21 , a driver 22 and a propeller 23 . The frame 10 is provided with a wave pressing part 11. The wave pressing part 11 has a first accommodation cavity 111. The wave pressing part 11 is used to contact the water flow of the water area. The motor 21 is installed on the frame 10 for outputting rotational torque. The driver 22 is fixed to the first accommodation cavity 111 and is electrically connected to the motor 21 to control the operation of the motor 21 . The driver 22 performs heat exchange with the water flow through the wave pressing part 11 . The propeller 23 is installed on the frame 10 and can receive the rotation torque of the motor 21.

When the propeller 100 is running, the frame 10 extends into the water, and the wave pressure part 11 is located at the water surface P of the water area. The water flow in the water area can generate heat exchange with the wave pressure part 11 and further heat exchange with the driver 22 located in the wave pressure part 11 Heat exchange is performed, thereby effectively reducing the heat generated by the driver 22 during the operation of the control motor 21 and improving the heat dissipation effect of the drive structure of the thruster 100 . It can be understood that the wave pressing part 11 can suppress the water waves stirred up by the propeller 23 and reduce the wave energy of the water waves, that is, reduce the energy consumption, so that the propeller 100 has higher propulsion efficiency.

Since the propeller 100 of this embodiment realizes heat exchange through the wave pressure part 11 located at the water surface P of the water area, the water flow rate at the wave pressure part 11 is relatively large, and the water flow quickly dissipates heat to the wave pressure part 11, so that the exchange rate of the driver 22 is The thermal efficiency is high, and there is no need to install additional cooling systems such as water pumps or oil pumps. On the premise of ensuring the heat dissipation effect of the driver 22, the production cost is reduced, and the volume and weight of the thruster 100 are reduced, thereby improving the user experience of the thruster 100. In addition, compared with the existing solid wave-pressing structure, the wave-pressing part 11 in the embodiment of the present application requires less modification to open the first accommodation cavity 111, which can ensure that the wave-pressing part 11 suppresses the water waves stirred by the propeller 23. Reducing energy waste can also further improve the heat dissipation effect of the driver 22, thereby improving the propulsion efficiency of the thruster 100. Therefore, the thruster 100 of this embodiment has simple installation and high heat dissipation efficiency, and will not affect the performance of the thruster 100 itself, thereby taking into account both propulsion performance and heat dissipation performance.

In some embodiments, referring to FIGS. 2 to 4 , the motor 21 is received in the first accommodation cavity 111 , and the motor 21 exchanges heat with the water flow through the wave pressing part 11 .

Since the motor 21 will also generate heat during actual operation, after the motor 21 is installed in the first accommodation cavity 111, the heat of the motor 21 can also be transferred to the wave pressing part 11, and the wave pressing part 11 can then exchange heat with the water flow to achieve The heat exchange between the motor 21 and the water flow is carried out, thereby improving the heat dissipation efficiency of the motor 21, which is conducive to increasing the power of the motor 21, thereby improving the propulsion efficiency of the thruster 100.

In some embodiments, referring to FIGS. 2 and 3 , the wave pressing part 11 is provided with a middle partition 112 , which separates the first accommodation cavity 111 into a motor cavity 111 a and an electronic control cavity 111 b. The motor 21 It is accommodated in the motor cavity 111a, and the driver 22 is accommodated in the electric control cavity 111b.

When the motor 21 is running in the motor cavity 111a, the motor cavity 111a is often filled with media such as air or cooling oil. The central partition 112 can prevent the liquid medium in the motor cavity 111a from entering the electronic control cavity 111b and preventing it from damaging the driver 22 , thereby improving the service life of the driver 22. The middle partition 112 can ensure the sealing performance of the motor cavity 111a and the electric control cavity 111b at the same time. When one of the motor cavity 111a and the electric control cavity 111b accidentally gets water, it can ensure that the other one will not be affected, thereby improving the The service life of the motor 21 and the driver 22 can also facilitate maintenance of either one. In addition, the motor cavity 111a and the electronic control cavity 111b can also ensure that the motor 21 and the driver 22 are firmly installed in the wave pressing part 11 to avoid collision between the two.

In some embodiments, referring to FIG. 2 , the first cooling lubricant 41 is built into the motor cavity 111 a. The first cooling lubricant 41 cools down the motor 21 and reduces the rotation resistance of the motor 21 .

Since the motor cavity 111a and the electric control cavity 111b are isolated by the middle partition 112, the first cooling lubricant 41 will not enter the electric control cavity 111b and damage the driver 22. After the first cooling lubricant 41 is additionally provided in the motor cavity 111a, the first cooling lubricant 41 can exchange heat with the motor 21, and then transfer the heat transferred by the motor 21 to the wave pressing part 11, and the wave pressing part 11 interacts with the water flow. The heat exchange can have a cooling effect on the first cooling lubricant 41, thereby improving the heat transfer efficiency of the motor 21 to the wave pressing part 11, thereby further improving the cooling efficiency of the motor 21, and further reducing the rotation resistance of the motor 21 , the motor 21 can be easily replaced and upgraded to a higher power motor 21 to improve the propulsion performance of the thruster 100 .

In some embodiments, referring to FIG. 3 , the propeller 100 further includes a first cable 24 , which connects the motor 21 and the driver 22 . The central partition 112 is provided with a first threading hole 1121 and is connected to the first threading hole 1121 . The inner peripheral side wall of the hole 1121 tightly fits the first wire harness sealing member 51 , and the first cable 24 passes through the first wiring hole 1121 and tightly fits the first wire harness sealing member 51 .

The first cable 24 can facilitate the driver 22 to control the motor 21 accurately and efficiently, thereby adjusting the output power of the motor 21; the cooperation of the first threading hole 1121 and the first wire harness seal 51 can facilitate the connection between the first cable 24 and the motor 21. The drivers 22 are connected, and the isolation between the electronic control chamber 111b and the motor chamber 111a can still be ensured. Of course, in other embodiments of the present application, there is no need to additionally provide the first cable 24, and control between the driver 22 and the motor 21 can be realized through a wireless network, which is not specifically limited in the embodiment of the present application.

In addition, the first wire harness seal 51 in this embodiment can be an oil seal or other types of sealing structures, which need not be described again.

In some embodiments, referring to FIG. 2 , the propeller 100 further includes a first transmission mechanism 61 connecting the motor 21 and the propeller 23 . The first transmission mechanism 61 transmits the rotational torque of the motor 21 to the propeller 23 .

By disposing the first transmission mechanism 61 between the motor 21 and the propeller 23 , the positional relationship of the propeller 23 relative to the wave pressing part 11 can be easily adjusted according to the actual installation environment of the propeller 100 .

That is, the driving force output by the motor 21 needs to be reversed by the first transmission mechanism 61 in order to achieve the propulsion effect when the propeller 23 rotates. In this embodiment, since the axis direction of the output shaft 211 is perpendicular to the axis direction of the rotation axis of the propeller 23, one end of the first transmission mechanism 61 can be directly connected to the output shaft 211, and the other end of the first transmission mechanism 61 can be connected through a switch. The axial structure is connected to the propeller 23, so that the rotational torque output by the output shaft 211 only needs to undergo one reversal, thereby reducing the loss of its rotational torque during the reversal process.

The length is smaller than the outer diameter of the stator and rotor 212.

Since the length of the stator and rotor 212 in the extension direction of the output shaft 211 is smaller than the outer diameter of the stator and rotor 212, the motor 21 as a whole can be flat, reducing the overall height of the motor 21, thereby making it easier to install the motor 21 in the wave pressure portion 11. Furthermore, the contact surface between the top surface and the bottom surface of the motor 21 and the wave pressing part 11 is increased, which not only prevents the motor 21 from having an excessive influence on the shape of the wave pressing part 11, but also further improves the heat dissipation performance of the motor 21.

At the same time, the underwater accommodating cavity 121 can also provide an accommodating space for the first transmission mechanism 61. The underwater accommodating cavity 121 is isolated from the first accommodating cavity 111, which can ensure that when water accidentally enters the underwater accommodating cavity 121, water It is impossible to enter the first accommodation cavity 111 from the underwater accommodation cavity 121, thereby improving the reliability of the propeller 100.

In some embodiments, referring to FIG. 2 , the output shaft 211 extends to the underwater accommodation cavity 121 , and the power receiving end 613 and the power output end 614 of the first transmission mechanism 61 are both located in the underwater accommodation cavity 121 .
