[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0029] Figures 1-6 As shown, the present utility model provides a water surface propeller for a life buoy, which is used in combination with a life buoy or a common life buoy. Specifically, it includes a connecting frame detachably connected to the outer side of the life buoy housing. A power unit 6 and an energy unit 5 are detachably installed on the connecting frame. Starting the power unit 6 mainly includes a motor and a propeller, and the energy unit 5 mainly includes a power source. Through the detachable connecting frame, it is possible to cooperate with the life buoy to achieve rapid navigation on the water surface, so as to quickly rescue drowning people on the water.

[0030] The connecting frame mainly includes an upper snap ring 2, a lower bridge plate 3 and a pair of lower snap rings 4. A power supply box is fixed on the upper side of the upper snap ring 2, and other electronic components such as a battery and a control chip are stored in the power supply box. The power unit 6 is installed on the lower side of the lower snap ring 4.

[0031] The lower bridge plate 3 is bent to fit the lower side of the ring body 1. In addition, fitting pieces 21 extend downward from both ends of the upper snap ring 2. Locking portions 31 extend upward from both sides of the width of the lower bridge plate 3. A slot 311 is preset at the upper end of the locking portion 31. The fitting pieces 21 and the slot 311 are inserted and matched. At the same time, a clamping portion 22 extends on the fitting piece 21, and a clamping groove 312 matched with the clamping portion 22 is opened on the inner wall of the slot 311. The clamping portion 22 and the clamping groove 312 form a locking structure to realize the fixed connection between the upper snap ring 2 and the lower bridge plate 3. The fitting piece 21 has elastic deformation, and the clamping groove 312 penetrates through the locking portion 31. By pushing the clamping portion 22 out of the clamping groove 312, the fitting piece 21 can be pulled out of the slot 311 to realize the unlocking and separation between the upper snap ring 2 and the lower bridge plate 3.

[0032] The lower bridge plate 3 and the lower snap ring 4 also adopt a detachable connection structure to further improve the space flexibility and applicability during storage. Receiving plates extend from the lower side of the lower bridge plate 3 respectively, and a wedge block 32 is preset on the upper side of the receiving plate. A wedge groove 41 is preset on the lower side of the lower snap ring 4. The insertion and matching between the wedge block 32 and the wedge groove 41 realizes the quick disassembly and assembly between the lower bridge plate 3 and the lower snap ring 4.

[0033] In addition, one end of the lower snap ring 4 in the width direction is hinged with a limit cover 42. The limit cover 42 includes a pair of hinge rods. One end of the hinge rod is rotatably connected to the lower snap ring 4. A locking rod is fixed between the other ends of the two hinge rods. And the hinge rod is in a bent structure and can fit with the upper side of the ring body 1. On the other side of the width of the lower snap ring 4, a limit protrusion 43 is preset. The limit protrusion 43 can limit the movement of the locking rod, so as to realize the stable installation of the lower snap ring 4 on the ring body 1.

[0034] At the same time, a number of straps can be preset and installed on both sides of the width direction of the lower bridge plate 3, and the connection stability with the ring body 1 is further improved through the straps.

[0035] In addition, wire holes are preset on the upper snap ring 2 and the lower snap ring 4, and a wire groove 33 is preset on the upper side of the lower bridge plate 3. The electric wire can transmit electric energy to the motor through the wire holes and the wire groove 33, and at the same time avoid the exposure of the electric wire, improving the safety and aesthetics during use.

[0036] The working principle of the present utility model is:

[0037] Steps for installing the water surface thruster on the life buoy:

[0038] First, the lower snap ring 4 and the lower bridge plate 3 are assembled by using a wedge block 32 and a wedge groove 41.

[0039] Then, the lower snap ring 4 and the lower bridge plate 3 are attached and fixed to the lower side of the ring body 1, and are locked through the cooperation between the limit cover 42 and the limit protrusion 43.

[0040] Finally, the upper snap ring 2 is attached and fixed to the upper side of the ring body 1, and the fitting piece 21 is inserted into the slot 311, and the clamping portion 22 is matched with the clamping groove 312 to realize the fitting and locking.
