[0025] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0026] Example: Figure 1-5 As shown, the utility model provides a technical solution, a lifting thruster of a submersible cross-medium buoy, comprising a mounting block 1, a rotating shaft 2 is connected to the top of the mounting block 1, the rotating shaft 2 is connected to the output end of the driving mechanism of the buoy, an inner base 3 is connected to the top of the rotating shaft 2, an outer base 4 is installed outside the inner base 3, and four connecting ear plates 5 are installed outside the outer base 4;

[0027] A mounting hole 6 is provided in the middle of the connecting ear plate 5, a fixing screw 7 is clamped inside the mounting hole 6, the bottom of the fixing screw 7 is connected to a limited end 8, two pairs of limiting plates 9 are installed on the outside of the limiting end 8, a fixing nut 10 is threadedly connected to the top of the fixing screw 7, a connecting plate 11 is installed on the top of the fixing nut 10, a sealing shell 12 is installed on the outside of the connecting plate 11, the bottom ends of the fixing nut 10 and the sealing shell 12 are both fitted with the top of the connecting ear plate 5, and three fixing screws 10 are installed at equal angles on the top of each fixing nut 10. A connecting piece 11 is provided to facilitate the connection between the sealing housing 12 and the fixing nut 10. A connecting block 13 is sleeved on the outside of the fixing screw 7. A limiting clamping block 14 is installed on the outside of the connecting block 13. One end of the connecting block 13 is connected to a fixed end tube 15. A limiting sleeve 16 is slidably clamped on the outside of the connecting block 13. A blade 17 is rotatably clamped on the outside of the fixed end tube 15. One end of the limiting sleeve 16 is in an open trumpet shape. One end of the limiting sleeve 16 is in a close fit with one end of the blade 17, so as to facilitate the limiting of the blade 17 when it is deployed.

[0028] A connecting rod 18 is installed at one end of the blade 17 at the position corresponding to the fixed end tube 15, and there are two for each pair of limiting plates 9. The distance between each pair of limiting plates 9 is equal to the thickness of the limiting block 14. The fixed end tube 15 is rotatably connected to the connecting rod 18, and each limiting block 14 is connected between the two limiting plates 9, which is convenient for limiting the connection block 13. A folding groove 19 is provided on the top of the blade 17, and a rope loop 20 is embedded and installed at one end of the folding groove 19. After the rope loop 20 is flattened, one end is connected to the inner side of the folding groove 19. Two rope loops 20 are provided, and the two rope loops 20 are respectively installed at the end positions of the two blades 17 on the same side, which is convenient for limiting the blade 17.

[0029] The working principle and use process of the utility model are as follows: before the snorkeling buoy enters the water, the limiting sleeve 16 is slid to separate from the blade 17, and then the blade 17 is rotated upward to make the blades 17 on both sides of the outer base 4 close to each other, and the two blades 17 close to each other are clamped through the folding groove 19 position, and then the rope loop 20 is put on the end of the blade 17 to limit one end of the blade 17, so that the blade 17 is folded up, the resistance is reduced underwater, and the blade 17 is not easily damaged;

[0030] When the paddle 17 is in use, the driving device of the buoy drives the rotating shaft 2 to rotate, so that the inner base 3, the outer base 4 and the paddle 17 rotate simultaneously. The paddle 17 is located on both sides of the outer base 4, and generates centrifugal force to expand to both sides when rotating at high speed. At the same time, the limiting sleeve 16 also slides toward one end of the paddle 17 due to the centrifugal force, thereby engaging with one end of the paddle 17, limiting the paddle 17, keeping it in an expanded state, so that the paddle 17 can work normally;

[0031] By folding the blades 17 underwater, the resistance and damage to the blades 17 underwater are reduced, and the blades 17 are unfolded on the water by the centrifugal force of the rotation. The blades 17 can be unfolded automatically, and the structure is simple and compact, and it is not easy to increase the burden of the snorkeling buoy;

[0032] A limiting block 14 is set on the outside of the connecting block 13 of the blade 17, and is limited by the connecting piece 11 of the fixing nut 10, so that the installation is more stable and can remain stable during rotation. A connecting piece 11 and a sealing shell 12 are set on the outside of the fixing nut 10 to protect the fixing nut 10 and prevent it from loosening easily.

[0033] Finally, it should be noted that the above description is only a preferred example of the present utility model and is not intended to limit the present utility model. Although the present utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
