Abstract

The invention relates to the technical field of waste water treatment equipment, and discloses a submersible electric pump automatic coupling device. A supporting frame is included. A coupling devicebody is fixedly arranged on the upper surface of the supporting frame. A water discharging pipe is fixedly arranged at one end of the coupling device body. A sliding rod is fixedly arranged at the middle portion of the upper surface of the coupling device body. A platform is fixedly arranged above the coupling device body. The other end of the coupling device body is movably provided with an additional coupling flange. The upper part of the additional coupling flange is connected with the sliding rod in a clamped manner. Compared with the prior art, cooperative installation of a sliding block,a rope fixing ring and a wheel, an elevating rope is directly connected to the rope fixing ring, the sliding block and the wheel, a submersible electric pump is constantly kept with the effect parallel to the sliding rod in the collecting and releasing process, and it is guaranteed that in the vertical face of the additional coupling flange in the collecting and releasing process, the problem ofadditional coupling flange bending due to the large weight of the submersible electric pump is solved.

Description

technical field [0001] The invention relates to the technical field of sewage treatment equipment, in particular to an automatic coupling device for a submersible electric pump. Background technique [0002] The coupling device is an automatic coupling device for automatic docking between the outlet flange of the submersible electric pump and the outlet pipeline system. It is composed of the outlet flange of the submersible electric pump, the additional coupling flange and the inlet flange of the outlet pipe seat. There is a pair of wedges on both sides of the inlet flange of the outlet pipe seat, and the position of the wedges is near the horizontal centerline of the flange. The wedges on both sides of the inlet flange of the water pipe seat are stuck together. Under the action of the submersible pump’s own weight and the wedge’s inclined surface, the two flanges are tightly attached to each other. No matter how high the water pressure of the submersible pump is, it cannot ...
