Automatic fixing and protecting device for stainless steel submersible pump

Abstract

The invention relates to the technical field of submersible pumps, and discloses an automatic fixing and protecting device for a stainless steel submersible pump. The automatic fixing and protecting device comprises a water inlet pipe, wherein a piston plate is connected to the inner wall of the water inlet pipe in a sliding mode; a first ejector rod is fixedly installed at the bottom end of the piston plate; a first conductive block is fixedly installed at the bottom end of the first ejector rod; a first spring is fixedly installed at the bottom end of the piston plate; the other end of the first spring is fixedly connected with a bottom plate; a second conductive block is fixedly installed on the upper surface of the bottom plate; a supporting rod is fixedly connected to the bottom end of the bottom plate; the other end of the supporting rod is fixedly connected with the inner side wall of the water inlet pipe; air bags are fixedly installed inside the inner walls of the two sides ofthe water inlet pipe; a fixing box is fixedly installed at the bottom end of the water inlet pipe; an electromagnet is fixedly installed on the inner wall of the left side of the fixing box; and a second spring is fixedly installed on the inner wall of the left side of the fixing box. The automatic fixing and protecting device is simple in structure and convenient to fix, and has an automatic alarm function.

Description

technical field [0001] The invention relates to the technical field of submersible pumps, in particular to an automatic fixing protection device for stainless steel submersible pumps. Background technique [0002] The submersible pump is a widely used water lifting tool, which is mostly used for lifting water in wells for agricultural irrigation, industrial use, and domestic drinking. During the water lifting process of the submersible pump, the internal rotor of the motor drives the water wheel to turn up the water, and the rotation of the rotor has a strong reverse thrust on the stator of the motor, and the stator is integrated with the outer shell of the submersible pump. [0003] If the outer casing of the submersible pump is suspended or placed in the water tank without fixed facilities, the outer casing of the submersible pump will often reverse, and it is easy to cause the submersible pump to shake a lot and the connection is unstable, which will affect the normal ope...
