Description

Technical Field

[0001] This utility model relates to the field of sewage pumping stations, and in particular to a prefabricated pumping station. Background Technology

[0002] With social development, the demand for sewage discharge in rural and urban areas is increasing, leading to the emergence of various drainage equipment. Integrated pumping stations, with their advantages of small footprint, factory prefabrication, and short construction period, are widely used in sewage systems. Their main function is to be installed in the sewage pipeline system to raise the elevation of sewage, allowing it to flow by gravity to the intercepting sewer network and ultimately be transported to the sewage treatment plant.

[0003] Chinese patent document CN104265615B discloses an integrated prefabricated pump station, including a casing with an inlet on the lower side and an outlet on the upper side. A sewage pump is located at the bottom of the casing, and the sewage pump is connected to the outlet via a pipe. Using this solution, the integrated prefabricated pump station only needs to be transported to the site for installation. However, the angle between the inlet and outlet in this solution is fixed. If there is a deviation in the connection angle with the existing inlet and outlet pipes, additional adapter pipes need to be fabricated, increasing the connection difficulty and reducing the tolerance for error.

[0004] Furthermore, Chinese patent application CN107083791A discloses a prefabricated pump station simplified structure, including a shell, which is a segmented structure connected by steel strips. While this approach allows the inlet and outlet to be located on different segments of the shell, enabling adjustment of the angle between them, it also prevents pre-installation of the piping between the outlet and the sewage pump. This necessitates on-site installation, and if the final inlet angle differs from the design angle, the piping needs to be redesigned and reassembled, impacting construction progress.

[0005] Meanwhile, the aforementioned pumping stations are not very efficient, and some large impurities may affect the efficiency of sewage discharge.

[0006] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a new type of prefabricated pumping station with greater industrial value. Utility Model Content

[0023] In this embodiment, the pump station cylinder 2 is composed of a cylinder base, a cylindrical cylinder wall, and a cylinder top cover, which are connected by welding. The pump station cylinder 2 is made of stainless steel.

[0024] In this embodiment, two water pumps 9 are provided, and the two water pumps can work simultaneously to improve the efficiency of sewage discharge.

[0025] In this embodiment, the maintenance platform 13 includes a maintenance mounting ring 131, a maintenance platform support 132, and a maintenance platform 133. The maintenance mounting ring 131 is installed on the inner wall of the pump station cylinder 2, the maintenance platform support 132 is installed between the maintenance mounting rings 131, and the maintenance platform 133 is installed between the maintenance platform supports 132.

[0030] During the above-mentioned sewage discharge process, the sealing plate is in a closed state to prevent sewage from being discharged from the outlet pipe. If the flow rate is large, the sealing plate can be opened to discharge water that exceeds the height of the outlet pipe. At the same time, the water pump is also in operation.

[0031] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0032] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0033] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or vertical, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0034] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "set up," "install," "connect," and "link" should be interpreted broadly.
