Embodiment 1
[0028] A suspension device for a submersible pump, comprising an annular airbag 1 surrounding the submersible pump 01, a connecting structure connected between the annular airbag and the submersible pump, and the connecting structure includes a top ring set inside the annular airbag Frame 2, connected to the bottom of the top ring frame and extending downwards, has a lower sleeve part 3 with a sleeve ring part 32 for socketing the main body of the submersible pump. The outside of the top ring frame is glued or socketed with the annular airbag.
[0029] The suspending device of this application sets the submersible pump upright in the central ring cavity area of the annular air bag, which greatly increases the peripheral area of the righting submersible pump, so that the buoyancy of the air bag is not only used to float the submersible pump in the water, but also used to protect the submersible pump. It is in an upright state, and the submersible pump is mainly fixed through...
Embodiment 2
[0031] The difference from the above embodiment is that the inside of the top ring frame is provided with an adjustable elastic auxiliary ring 4 for straightening the submersible pump, and the elastic auxiliary ring is an elastic washer or an inner air bag ring.
[0032] The lower part of the submersible pump is connected to the ground and the ring is connected, and the upper part is connected to the elastic auxiliary ring to fix the water pump at two points. The elastic auxiliary ring can also buffer the shaking force of the submersible pump. The impact of the impact is not likely to drive the annular airbag to turn over, ensuring that the submersible pump is facing downward, which improves the stability of the submersible pump in the water.
[0033] The elastic auxiliary ring is provided with at least one perforation opening 41 for passing through the drain pipe of the submersible pump from bottom to top. The perforation opening communicates with the cavity of the elastic au...
Embodiment 3
[0036] The difference from the above embodiment is that the inner top of the top ring is provided with a limit ring edge 23 that limits the position of the inner airbag ring, and the limit ring is a split ring that is provided with an opening corresponding to the perforation port. The inner airbag ring is glued on the top ring frame. The limit ring can ensure that the inner airbag ring is not easy to turn upwards, and ensure the radial extrusion effect on the submersible pump as much as possible. The downward deformation space of the inner airbag ring is mainly restricted by the lower sleeve parts, and the displacement space is limited.
