Description

Technical Field

[0001] This utility model relates to the technical field of submersible pump installation, and in particular to an open installation structure for low-head pumps. Background Technology

[0002] Axial-flow submersible pumps and mixed-flow submersible pumps are traditional water pump products that can operate submerged in water for extended periods. They are widely used in agricultural irrigation and drainage, industrial and mining operations, shipbuilding, urban water supply and drainage, and water supply projects. Axial-flow submersible pumps typically have a discharge capacity of over 500 cubic meters per hour, and a head generally not exceeding 20 meters.

[0003] For high specific speed submersible axial flow pumps, traditional installation methods cannot adequately meet the needs in drainage in low-lying, flood-prone areas near lakes and in urban sewage treatment. Utility Model Content

[0004] This invention aims to address the shortcomings of existing technologies by providing an open mounting structure for low-head electric pumps.

[0005] To achieve the above objectives, this utility model adopts the following technical solution:

[0006] An open installation structure for a low-lift electric pump includes a lower concrete slab and an upper concrete slab. A lower concrete sealing plate is provided between the lower and upper concrete slabs. An upper concrete sealing plate and a concrete installation plate are provided on the upper concrete slab. A concrete top plate is provided on the top of the upper concrete sealing plate and the concrete installation plate. The lower concrete sealing plate is located between the upper concrete sealing plate and the concrete installation plate. A filter screen is provided at the open end opposite to the lower concrete sealing plate between the lower and upper concrete slabs. A well is installed on the lower concrete slab between the upper and lower concrete sealing plates. A seat ring is installed at the bottom of the well. A submersible electric pump is installed inside the well. The lower end of the submersible electric pump is supported on the seat ring. A cover plate is installed directly above the well on the concrete top plate. A lifting rod is installed on the cover plate and fixed to the submersible electric pump. A cable is tied to the lifting rod and connected to the submersible electric pump. The cable passes through the cover plate in a sealed manner. A wall-penetrating pipe is installed on the concrete installation plate, and a flap valve is installed at the outer end of the wall-penetrating pipe.

[0007] The well shaft is a tapered structure that is wider at the top and narrower at the bottom. The top of the well shaft is equipped with a support ring plate and the bottom is equipped with a connecting ring plate. A support seat is provided between the bottom of the support ring plate and the top of the upper concrete slab. The support seat is a side-mounted U-shaped structure. The bottom plate of the support seat is fixed to the upper concrete slab by anchor bolts. The connecting ring plate and the seat ring are fixedly connected by bolts.

[0008] The inner side of the seat ring is provided with a tapered protective sleeve that is wider at the top and narrower at the bottom.

[0009] The inclination angle of the conical casing is 60°.

[0010] The beneficial effects of this utility model are: This utility model utilizes the concrete structure and well structure in combination to install the submersible pump in an open manner, which is suitable for the installation of low-head pumps and is more suitable for use in drainage in low-lying and flood-prone areas near lakes and in urban sewage treatment.
