The propelling paddle 102 and the installation disc 107 can be fixedly connected through a plurality of bolts to increase the fixed points and further improve the stability of the propelling paddle 102 after installation.

[0028] Optionally, in some possible embodiments, a fairing 103 is arranged on the side of the driving motor 108 away from the propelling paddle 102, the fairing 103 is sleeved on the side of the driving motor 108, and the fairing 103 is detachably connected with the mounting shell 101.

[0029] As shown in Figure 1 and Figure 2 , the mounting pipe 202 is vertically arranged on the unmanned device, generally, the propelling device needs to propel the unmanned device in the horizontal direction, therefore, the rotating shaft of the driving motor 108 is perpendicular to the axis direction of the mounting pipe 202 to ensure that the propelling paddle 102 generates propelling force in the horizontal direction. After the driving motor 108 is installed, the side of the mounting shell 101 close to the propelling paddle 102 is the water outlet end, and the side of the mounting shell 101 away from the propelling paddle 102 is the water inlet end. The fairing 103 is arranged on the side of the water inlet end of the mounting shell 101, the fairing 103 is sleeved on the side of the driving motor 108, cooperates with the mounting shell 101 to form a relatively sealed installation cavity, and the driving motor 108 is arranged in the installation cavity. The fairing 103 can protect the driving motor 108, avoid the driving motor 108 from being impacted by external liquid or solid substances, and ensure the safety and service life of the driving motor 108.

[0030] Optionally, in some possible embodiments, the mounting shell 101 is provided with a filter assembly on the side away from the propeller 102.

[0031] The filter assembly provided on the water inlet end of the mounting shell 101 can filter impurities in the liquid, so as to avoid waterweeds, solid waste, animals, etc. from passing through the propeller 102, thereby avoiding the propeller 102 from being damaged due to impact, and avoiding long strip-shaped objects from being entangled with the propeller 102, thereby avoiding the driving motor 108 from being damaged.

[0032] Optionally, in some possible embodiments, the filter assembly comprises a water inlet mesh cover 104 and a filter mesh cover 105, the water inlet mesh cover 104 is connected with the mounting shell 101, and the water inlet mesh cover 104 is provided with a water inlet hole, the filter mesh cover 105 is sleeved on the water inlet mesh cover 104, and the filter mesh cover 105 is detachably connected with the water inlet mesh cover 104.

[0033] Please refer to Figure 1 and Figure 2 , the water inlet mesh cover 104 is detachably connected with the mounting shell 101, and the water inlet mesh cover 104 forms a support structure on the water inlet end of the mounting shell 101, thereby protecting the mounting shell 101 and the driving motor 108 inside. The water inlet mesh cover 104 is mainly used to avoid the direct impact of objects on the driving motor 108, so as to avoid the driving motor 108 from being damaged due to impact. During use, under the power of the driving motor 108, the entire propulsion device has a certain conveying speed, at this time, even the stationary objects in the external environment will also move relatively fast with respect to the propulsion device, and it is extremely easy to collide with the propulsion device. At this time, the water inlet mesh cover 104 can block foreign matter, so as to avoid the direct impact of objects on the driving motor 108. The water inlet mesh cover 104 is provided with the filter mesh cover 105, the filter mesh cover 105 can be arranged on the outer wall or the inner wall of the water inlet mesh cover 104, and the filter mesh cover 105 is mainly used to filter small foreign matter such as waterweeds, animals, solid particles, etc., so as to avoid the entanglement of the propeller 102, thereby avoiding the propeller 102 from being stuck. The filter mesh cover 105 is detachably connected with the water inlet mesh cover 104, so as to facilitate cleaning. It can be understood that when too much impurity is accumulated on the filter mesh cover 105, the filter holes of the filter mesh cover 105 will be blocked, thereby affecting the water inlet effect and the propulsion effect, and the filter mesh cover 105 needs to be cleaned. The filter mesh cover 105 is detachably connected with the water inlet mesh cover 104, so that the filter mesh cover 105 can be directly detached during cleaning, thereby reducing the operation difficulty during cleaning and improving the cleaning efficiency.

[0037] Please refer to Figure 1 and Figure 2 As shown, the propeller 102 is provided with the propelling nozzle 106, which can form a protective cover to avoid the propeller 102 from contacting the external environment, thereby ensuring the safety of the propeller 102. In addition, the propeller 102 can guide the flow of liquid, so that the liquid is sprayed from the opening of the propelling nozzle 106, thereby generating a greater propelling force and improving the propelling effect. Optionally, in some possible embodiments, the propelling nozzle 106 can be provided in a funnel structure. The funnel-shaped propelling nozzle 106 forms a smaller water outlet, and when the liquid flows through the propelling nozzle 106, the liquid accelerates and is sprayed from the water outlet, thereby forming a stronger propelling force and further improving the propelling effect.

[0038] Optionally, in some possible embodiments, the connecting rod 201 is provided with a wire hole 2011 in the axial direction, and the wire cable 400 is arranged in the wire hole 2011. The driving motor 108 is electrically connected to the power supply device through the wire cable 400.

[0039] The driving motor 108 needs to be connected to the power supply device and the control device, and needs to be connected to the wire cable 400. Therefore, the connecting rod 201 is provided in a hollow structure, and the power cable 400 and the control cable 400 pass through the inside of the connecting rod 201 and are connected to the driving motor 108. The inside of the connecting rod 201 directly communicates with the mounting cavity in the inside of the mounting shell 101, thereby ensuring the sealing of the driving motor 108 and the wire cable 400.

[0040] Optionally, in some possible embodiments, the wire hole 2011 is provided with a waterproof plug 500.

[0041] The waterproof plug 500 can be made of rubber or silicone, and forms an interference fit with the inner wall of the wire hole 2011, thereby achieving a sealing effect. The waterproof plug 500 can prevent liquid from entering the mounting cavity in the mounting shell 101 from the top of the connecting rod 201, thereby preventing the liquid from contacting the driving motor 108 or the wire cable 400 to cause short circuit or corrosion of the electronic elements, and ensuring the service life of the driving motor 108.
