[0021] It should be understood that the present invention uses the terms "front", "back", etc. to describe various information, but these information should not be limited to these terms, and these terms are only used to distinguish the same type of information from each other. For example, "front" information may also be referred to as "back" information, and "back" information may also be referred to as "front" information without departing from the scope of the present invention.

[0022] like Figures 1 to 4 As shown, the present invention provides a foldable floating boat pump, which includes a submersible pump 1, a rectangular frame 2 and a float 3. The submersible pump 1 is fixedly connected to the frame 2 through a first connecting member 21, and the float 3 is connected to the frame 2 through a folding device 4. Specifically, the folding device 4 includes a fixed seat 41, a folding seat 42, a rotating seat 43 and a collar 44. The fixed seat 41 is fixedly connected to the frame 2, the folding seat 42 is hingedly connected to the fixed seat 41 through a second leveling member 45 and can rotate 180° around the hinge axis, the rotating seat 43 is hingedly connected to the folding seat 42 through a third connecting member 46 and can rotate 90° around the hinge axis, the collar 44 is fixedly connected to the rotating seat 43 through a fastening bolt, and the float 3 is arranged in the collar 44.

[0023] Based on the above structure, when the foldable floating boat pump is stored, the ring 44 is parallel to the frame 2 and is located in the frame 2. When in use, the folding seat 42 is rotated to take the ring 44 out of the frame 2, and then the rotating seat 43 is rotated to make the ring 44 perpendicular to the frame 2, and the uninflated float 3 is placed in the two rings 44 located on the same side of the frame 2. The float 3 is inflated using an electric air pump. The inflated float 3 expands and squeezes the ring 44 to fix the float 3 and the ring 44. The submersible pump 1 and the frame 2 are connected by the first connecting member 21, and the foldable floating boat pump can be put into the water for use. In this way, the frame 2 of the foldable floating boat pump is hingedly connected to the folding device 4, and the operator can fold the ring 44 and put it into the frame 2 as needed, which can effectively reduce the space occupied by the foldable floating boat pump.
