Suspension device of submersible pump

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...

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
