[0020] Example one, as Figs. 1-3 Indicated, a water jet propeller for water navigation, including the pump housing 1, the pump housing 1 is provided with motor cavity 2, transmission cavity 3 and water inlet cavity 4 respectively, motor cavity 2 is located above water inlet cavity 4, water inlet cavity 4 left end fixedly installed with spray head 8, motor cavity 2 is fixedly installed with drive motor 5, transmission cavity 3 is equipped with transmission assembly, water inlet cavity 4 is connected with drive shaft 6 through bearing horizontal rotation, the output shaft of drive motor 5 passes through motor cavity 2 and is connected with the input end of transmission assembly, one end of drive shaft 6 passes through water inlet cavity 4 and is connected with the output end of transmission assembly, the other end of drive shaft 6 is connected with one end of impeller center shaft 7 through coupling, the other end of impeller center shaft 7 is fixedly installed with impeller 9, impeller 9 is movably connected in spray head 8;The bottom of the pump housing 1 is fixedly embedded with water inlet grid 14, water inlet cavity 4 is communicated with external water area through water inlet grid 14,

[0021] The upper portion of the pump housing 1 is fixedly installed with support plate 10, the support plate 10 is fixedly installed with U-shaped hanging plate 11, the left side of support plate 10 is fixedly installed with control box 12, the left side of support plate 10 is fixedly covered with outer shell 13, the lower end of outer shell 13 is sealingly connected with pump housing 1, control box 12 is located in the inside of outer shell 13, control box 12 is connected with the control port of drive motor 5 through cable.

[0022] Working principle:

[0023] In use, the U-shaped hanging plate 11 can be hung on the rear side of the ship body through the hanging function, and in this embodiment, a pressing bolt can be connected to the right side of the U-shaped hanging plate 11 through a threaded connection, so that when the U-shaped hanging plate 11 is hung on the rear side of the ship body, the pressing bolt can be tightened to firmly fix the propeller. At this time, the spray pump shell 1 is submerged below the water surface, ensuring that the water inlet grid 14 is completely submerged below the water surface. At this time, the bottom of the spray pump shell 1 will not exceed the bottom of the ship body, so that the spray pump shell 1 can effectively avoid collision with underwater obstacles below the ship body, ensuring safe navigation.

[0024] When working, the drive motor 5 is started through the control box 12, so that the output shaft of the drive motor 5 drives the drive shaft 6 to rotate through the transmission assembly, so that the drive shaft 6 drives the impeller center shaft 7 and the impeller 9 to rotate at high speed, and the water in the water inlet cavity 4 is sucked into the water inlet grid 14 and accelerated to be sprayed out, forming a strong thrust to push the ship body forward. Thus, efficient water navigation is achieved. And it can effectively avoid the power loss or failure caused by the entanglement of water grass, debris and the like, and ensure the continuous and stable propulsion effect.

[0025] In this embodiment, a communication module can be provided in the control box 12 for receiving remote instructions to adjust the speed of the drive motor 5, so as to realize precise control of the propulsion force and improve the stability and flexibility of navigation. At the same time, the sealing design of the outer shell 13 effectively prevents water immersion and ensures the safe operation of the internal components. And by arranging the water inlet grid 14 at the bottom of the spray pump shell, the water intake path is optimized, the resistance is reduced, the water intake efficiency is improved, and the air entering the water inlet cavity is effectively avoided, further improving the overall performance and reliability of the propeller.

[0027] Specifically, the angle adjusting assembly includes a servo motor 16, a double-head screw 17 and a rotating bracket 18, the servo motor 16 is fixedly installed on the side wall of the spray pump shell 1 through a mounting bracket 19, the output shaft of the servo motor 16 is fixedly connected with one end of a transmission arm 20, the two ends of the double-head screw 17 are respectively threaded with a first joint bearing 21 and a second joint bearing 22, the first joint bearing 21 is rotatably connected with the other end of the transmission arm 20 through a rotating shaft, and the second joint bearing 22 is rotatably connected with one end of the rotating bracket 18 through a rotating shaft, and the other end of the rotating bracket 18 is fixedly connected with the nozzle 15. The control port of the servo motor 16 is connected with the control box 12.

[0028] Therefore, in use, when the water jet direction needs to be adjusted, the control box 12 sends a command to the servo motor 16, so that the servo motor 16 drives the transmission arm 20 to rotate through the output shaft, and then drives the rotating bracket 18 and the nozzle 15 to rotate around the connecting shaft through the transmission of the double-headed screw rod 17, so as to effectively control the angle of the nozzle 15, and then accurately adjust the water jet direction, meet the needs of different navigation conditions, and further improve the navigation control and adaptability.

Therefore, when the driving motor 5 is started, the driving gear 23 is driven to rotate through the output shaft of the driving motor 5, and the driving gear 23 and the driven gear 24 are connected through the transmission belt, so that the driven gear 24 and the driving shaft 6 are driven to rotate synchronously, and then the jet pump impeller 7 is driven to rotate at high speed through the rotation of the driving shaft 6, forming a strong water jet.
