Problems solved by technology

Regardless of the above structure or the structure with built-in airbags, it is difficult to ensure that the self-heavy submersible pump is generally in a vertical state under the impact of water flow or external force, so it is impossible to ensure that the water inlet is always in the water or the water inlet is always in the vertical state. Next
Moreover, most of the existing submersible pumps and airbag structures are well-matched, one-to-one form. If the pump is broken or the airbag is broken, it will be troublesome, which may lead to the abandonment of the submersible pump, and the submersible pumps on the market that do not have the suspension function are also Cannot be applied, resulting in higher cost and short life of suspendable submersible pumps

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.

Abstract

The invention belongs to the field of submersible pumps, and particularly relates to a suspension device of a submersible pump. The device comprises an annular air bag annularly arranged outside the submersible pump and a connecting structure connected between the annular air bag and the submersible pump, the connecting structure comprises a top ring frame arranged in the annular air bag in a sleeving mode and a lower sleeving part connected to the bottom of the top ring frame and extending downwards to be provided with a sleeving ring part which is connected with a submersible pump main bodyin a sleeving mode, and the outer side of the top ring frame is connected with the annular air bag in a gluing or sleeving mode. According to the suspension device, the submersible pump is verticallyarranged in the central annular cavity area of the annular air bag, the peripheral area for centralizing the submersible pump is greatly increased, so that the buoyancy of the air bag is not only usedfor floating the submerged pump in water, but also used for embosoming the submerged pump and guaranteeing the standing state of the submersible pump, the submersible pump is fixed mainly through thelower sleeving part, so that the submerged pump can be vertically erected in the water as far as possible through the penetrating connection mode, a water inlet can be guaranteed to sink into the water, and the water inlet effect is ensured.

Description

technical field [0001] The invention belongs to the field of submersible pumps, and in particular relates to a suspension device of a submersible pump. Background technique [0002] In the existing submersible pumps with airbags, the airbags are generally placed in the pump body structure to ensure buoyancy or directly connected by simple ropes. For example, a submersible pump suspension device disclosed in the application number "201720515609.1" includes the submersible pump body. Suspended in the water, the suspended body is connected with the submersible pump body through a connecting rope, and the suspended body is an air bag structure with an inflatable inner cavity. Regardless of the above structure or the structure with built-in airbags, it is difficult to ensure that the self-heavy submersible pump is generally in a vertical state under the impact of water flow or external force, so it is impossible to ensure that the water inlet is always in the water or the water i...
