Description

Technical Field

[0001] This utility model relates to a fixed submersible axial flow pump station, belonging to the technical field of submersible pump stations. Background Technology

[0002] In the field of water conservancy engineering, pumping stations, as key water conveyance equipment, undertake important functions such as regulating water volume and raising water levels. However, traditional fixed pumping stations require optimization in design and construction. Traditional fixed pumping stations have high construction costs and low installation efficiency. Traditional fixed pumping stations typically require extensive civil engineering work, including foundation pit excavation, construction of the main pumping station structure, and installation of supporting equipment. These construction stages are not only time-consuming and labor-intensive but also require specialized construction teams and complex construction equipment, increasing construction and time costs, thus resulting in low installation efficiency and a cumbersome, time-consuming process. This prevents pumping stations from being put into use quickly, affecting the overall progress of water conservancy projects. It is against this backdrop that the patent for fixed submersible axial flow pumping stations has emerged, aiming to solve existing problems through technological innovation. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a fixed submersible axial flow pump station to simplify the installation process, reduce construction costs, and significantly improve the installation efficiency and usage flexibility of the pump station, thereby meeting the needs of water conservancy projects for efficient and reliable water conveyance equipment.

[0004] The fixed submersible axial flow pump station of this utility model includes a submersible axial flow pump, a pump cylinder, and a well. The submersible axial flow pump is installed at the bottom of the vertical pump cylinder. The submersible axial flow pump and the pump cylinder are located inside the vertical well. A well flange is provided at the bottom of the well. The well is fixed to a concrete platform on the bottom of the water by a fixing device. The fixing device is a screw with a foot plate at the bottom. The bottom of the screw is embedded in the concrete platform and the top of the screw extends above the concrete platform. The top of the screw passes through the well flange, and a fixing nut is installed on the well flange and screwed on the screw.

[0005] This invention only requires a pre-formed concrete platform with the screw embedded in it during the forming process. During installation, the well flange is hoisted, and the well flange is connected to the screw and fixed with nuts. The installation is fast and efficient, and the construction cost is low.

[0006] Preferably, the screws are provided in multiple sets, forming a rectangular array and connected by a positioning frame. The positioning frame is also pre-embedded in the concrete base. The function of the positioning frame is to maintain a reasonable spacing between the multiple sets of screws and prevent mismatch with the well flange.

[0007] Preferably, the screw and the positioning frame are detachably connected. The screw passes through the positioning frame, and height adjustment nuts are provided on the upper and lower sides of the positioning frame on the screw, so as to facilitate the adjustment of the positioning frame and make its four corners consistent in height.

[0008] The pump cylinder of this utility model has a herringbone wall outside the water inlet and a debris screen at the water inlet.

[0009] The advantages of this utility model compared with the prior art are:

[0010] 1. Simplified installation process and improved installation efficiency: By adopting a pre-formed concrete platform with pre-embedded bolts, this invention greatly simplifies the installation process of the pump station. During installation, it is only necessary to hoist the well flange and connect it with the bolts, then fix it with nuts. There is no need for complex civil construction and installation of supporting equipment, which not only significantly improves installation efficiency but also shortens the construction cycle of the pump station, enabling it to be put into use more quickly.

[0011] 2. Reduced construction costs: By reducing the amount of civil engineering work and the installation of supporting equipment, the construction cost of this utility model is effectively reduced. At the same time, the simpler and faster installation process also reduces the input of manpower and materials, further lowering costs. Attached Figure Description
