Description

Technical Field

[0001] This utility model relates to the field of pump station technology, specifically providing a prefabricated pump station. Background Technology

[0002] Prefabricated pumping stations are integrated products that combine submersible pumps, pumping station equipment, sludge removal screens, control systems, and remote monitoring systems. Prefabricated pumping stations are characterized by their mobility, extremely short construction period, and ease of installation. They are becoming a new trend in pumping station construction in China's municipal engineering industry.

[0003] When overhauling a prefabricated pumping station, operators enter through the top access port, climb a ladder into the cylinder, and then stand on the maintenance platform to perform the maintenance. However, submersible pumps are usually located at the bottom of the pumping station, making them inaccessible through the maintenance platform.

[0004] Accordingly, a new technical solution is needed in this field to solve the above problems. Utility Model Content

[0005] The present invention aims to solve the above-mentioned technical problems and address the difficulty in maintaining submersible pumps in existing pumping stations.

[0006] This utility model provides a prefabricated pumping station, comprising: a cylinder with an inspection port at its upper end, an inlet and an outlet on the side wall of the cylinder, the outlet being located above the inlet; a guide rail assembly placed inside the cylinder and arranged along the height direction of the cylinder; a submersible pump assembly disposed below the inlet inside the cylinder and configured to discharge the medium inside the cylinder through the outlet; the submersible pump assembly having a sliding hole slidably connected to the guide rail assembly, the submersible pump assembly being configured to move along the length direction of the guide rail assembly; and a lifting assembly including a lifting drive and a connecting cable, the lifting drive being connected to the upper end of the cylinder, one end of the connecting cable being connected to one end of the lifting drive, and the other end of the connecting cable being connected to the submersible pump assembly, the lifting drive being configured to move the submersible pump assembly along the length direction of the guide rail assembly via the connecting cable.

[0007] With the above technical solution, the submersible pump can slide along the height of the cylinder to below the inspection port through the cooperation of the guide rail assembly and the lifting assembly, allowing operators to complete maintenance without entering the bottom of the cylinder. The sliding connection between the submersible pump assembly and the guide rail assembly supports quick disassembly and assembly, facilitating replacement or maintenance.

[0008] In the specific implementation of the prefabricated pumping station described above, the submersible pump assembly includes a pump body and a connector; the pump body is connected to the connecting cable, the pump body communicates with the connector, and the connector is provided with a sliding hole.

[0009] In the specific implementation of the prefabricated pumping station described above, the guide rail assembly includes two connector guide rails, which are slidably connected to the sliding hole.

[0010] With the above technical solution, the sliding hole cooperates with the two connector guide rails to ensure that the pump body moves without deviation or jamming. The separate design of the connector and the pump body reduces the risk of connection failure due to pump body shaking during the lifting process.

[0011] In the specific implementation of the prefabricated pumping station described above, the inlet is equipped with a screen, which is configured to filter the liquid entering the cylinder through the inlet.

[0012] In the specific embodiment of the prefabricated pumping station described above, a grid guide rail is provided on the inner wall of the cylinder, and the grid is slidably connected to the grid guide rail; and / or

[0013] A support frame is provided on the side wall of the cylinder at the lower end of the grid guide rail, and the support frame is configured to support the grid.

[0014] When the above technical solution is adopted, the bar screen filters impurities at the water inlet, preventing pump blockage. The bar screen guide rail and support frame design allows for quick removal and cleaning or replacement of the bar screen.

[0015] In the specific implementation of the prefabricated pumping station described above, a maintenance platform is provided on the lower side of the water inlet on the inner wall of the cylinder, and the maintenance platform is configured to allow maintenance personnel to stand on it.

[0016] In the specific implementation of the prefabricated pumping station described above, the maintenance platform includes a fixed crossbar, an overlapping crossbar, and a support plate; the fixed crossbar and the overlapping crossbar are fixedly connected to the cylinder; one end of the support plate is hinged to the fixed crossbar, and the other end of the support plate overlaps with the overlapping crossbar.

[0017] With the above technical solution adopted, the maintenance platform is located below the water inlet, providing a stable standing area and facilitating simultaneous maintenance of the pump and other equipment by operators. The support plate and overlapping crossbar are hinged, allowing for foldable storage to save space, and forming a stable support surface when unfolded.

[0018] In the specific implementation of the prefabricated pumping station described above, a ladder is provided inside the cylinder, leading from the upper inspection port to the maintenance platform.

[0019] With the above technical solution adopted, the ladder leads directly from the inspection port to the maintenance platform, reducing the risk of unprotected climbing inside the cylinder.

[0020] In the specific embodiment of the prefabricated pumping station described above, an inspection cover is movably provided at the upper end of the cylinder outside the inspection port, and the inspection cover is configured to be able to open or cover the inspection port.

[0021] In the specific implementation of the prefabricated pumping station described above, one end of the inspection cover is movably connected to the upper end of the cylinder, and the inspection cover fits against the upper end of the cylinder when closed.

[0022] When the above technical solution is adopted, the inspection cover is sealed and fits snugly against the cylinder when closed, preventing rainwater or foreign objects from entering the cylinder. Attached Figure Description

[0033] like Figures 1-5 As shown, to solve the problem of difficult maintenance of submersible pumps in existing pumping stations, this utility model provides a prefabricated pumping station, including: a cylinder 1, with an inspection port at its upper end; an inlet 11 and an outlet 12 on the side wall of the cylinder 1, with the outlet 12 located above the inlet 11; a guide rail assembly, which is placed inside the cylinder 1 and arranged along the height direction of the cylinder 1; a submersible pump assembly, which is located below the inlet 11 inside the cylinder 1 and is configured to discharge the medium inside the cylinder 1 through the outlet 12; the submersible pump assembly is provided with a sliding hole, which is slidably connected to the guide rail assembly, and the submersible pump assembly is configured to move along the length direction of the guide rail assembly; and a lifting assembly, which includes a lifting drive and a connecting cable, wherein the lifting drive is connected to the upper end of the cylinder 1, one end of the connecting cable is connected to one end of the lifting drive, and the other end of the connecting cable is connected to the submersible pump assembly, and the lifting drive is configured to move the submersible pump assembly along the length direction of the guide rail assembly via the connecting cable. Thus, through the cooperation of the guide rail assembly and the lifting assembly, the submersible pump can slide along the height of the cylinder 1 to below the inspection port, allowing operators to complete maintenance without entering the bottom of the cylinder 1. The sliding connection between the submersible pump assembly and the guide rail assembly supports quick disassembly and assembly, facilitating replacement or maintenance.

[0034] In one or more embodiments, the lifting assembly includes a lifting drive and a connecting cable. The lifting drive is connected to the upper end of the cylinder 1 and is a motor. The connecting cable is a chain, with one end connected to the lifting drive and the other end connected to the submersible pump assembly. By rotating the lifting drive, the connecting cable winds around the power output shaft of the lifting drive, thereby causing the submersible pump assembly to move upward.

[0035] like Figure 5 As shown, in one or more embodiments, the submersible pump assembly includes a pump body 32 and a connector 31; the pump body 32 is connected to a connecting cable and communicates with the connector 31, which has a sliding hole. The guide rail assembly includes two parallel connector guide rails 4, which are arranged along the length of the cylinder 1, and the sliding hole is slidably connected to the connector guide rails 4. Thus, the sliding hole cooperates with the two connector guide rails 4 to ensure that the pump body 32 moves without deflection or jamming. The connector 31 and pump body 32 are designed separately to reduce the risk of connection failure due to pump body 32 shaking during lifting. Alternatively, the guide rail assembly may also include one connector guide rail 4, with a corresponding anti-rotation protrusion in the sliding hole and an anti-rotation recess corresponding to the anti-rotation protrusion on the outside of the connector guide rail 4, so that the submersible pump assembly will not rotate relative to the connector guide rail 4 when moving along it. Furthermore, the number of submersible pump assemblies can also be two, and the corresponding number of guide rail assemblies and lifting assemblies can also be two.

[0036] like Figure 2 and Figure 3 As shown, in one or more embodiments, a grid guide rail 52 is provided on the inner sidewall of the cylinder 1, and the grid guide rail 52 is arranged along the height direction. A grid 51 is provided inside the cylinder 1 directly opposite the water inlet 11, and the grid 51 is configured to filter the liquid entering the cylinder 1 through the water inlet 11. Slider blocks are provided on both sides of the grid 51, and the sliders are located inside the grid guide rail 52, allowing the grid 51 to slide along the length direction of the grid guide rail 52. A support frame 53 is provided on the sidewall of the cylinder 1 at the lower end of the grid guide rail 52, and the support frame 53 is configured to support the grid 51. In this way, the grid 51 filters impurities from the water inlet 11, preventing the pump body 32 from becoming clogged. The grid guide rail 52 and the support frame 53 are designed to support the quick removal and removal of the grid 51 for cleaning or replacement. It should be noted that the installation of grille guide rail 52 and grille 51 is not mandatory. Those skilled in the art can choose whether to install grille guide rail 52 and grille 51 and the specific structure of grille guide rail 52 and grille 51 based on the specific application scenario. Of course, grille guide rail 52 and grille 51 can also be omitted.

[0037] like Figure 2 and Figure 4As shown, in one or more embodiments, a maintenance platform 7 is provided below the water inlet 11 on the inner wall of the cylinder 1. The maintenance platform 7 is configured to allow maintenance personnel to stand. The maintenance platform 7 includes a fixed crossbar 71, an overlapping crossbar 72, and a support plate 73. The fixed crossbar 71 and the overlapping crossbar 72 are fixedly connected to the cylinder 1. One end of the support plate 73 is hinged to the fixed crossbar 71, and the other end of the support plate 73 overlaps with the overlapping crossbar 72. When maintenance personnel need to stand on the support plate 73, one end of the support plate 73 overlaps with the overlapping crossbar 72, and the support plate 73 can support the maintenance personnel. When it is necessary to lift the pump body 32 from the lower side, the support plate 73 rotates around the fixed crossbar 71, allowing the pump body 32 to pass through. Thus, the maintenance platform 7 is located below the water inlet 11, providing a stable standing area, which facilitates the simultaneous maintenance of the pump body 32 and other equipment by the operator. The support plate 73 and the overlapping crossbar 72 are hinged, allowing for foldable storage to save space, and forming a stable support surface when unfolded. It should be noted that the installation of the maintenance platform 7 is not mandatory. Those skilled in the art can choose whether to install the maintenance platform 7 and its specific structure based on the specific application scenario, or of course, the maintenance platform 7 can be omitted.

[0038] like Figure 2 As shown, in one or more embodiments, a ladder 6 is provided inside the cylinder 1, leading from the upper inspection port to the maintenance platform 7. Thus, the ladder 6 provides direct access from the inspection port to the maintenance platform 7, reducing the risk of unprotected climbing inside the cylinder 1. Of course, the ladder 6 is not mandatory; those skilled in the art can choose whether to provide the ladder 6 and its specific structure based on the specific application scenario, or it may be omitted.

[0039] like Figure 1 and Figure 2 As shown, in one or more embodiments, a maintenance cover 2 is movably disposed at the upper end of the cylinder 1, outside the maintenance opening. The maintenance cover 2 is configured to be openable or to cover the maintenance opening. One end of the maintenance cover 2 is connected to the upper end of the cylinder 1 via a hinge, and when closed, the maintenance cover 2 fits snugly against the upper end of the cylinder 1. Thus, when closed, the maintenance cover 2 is sealed tightly against the cylinder 1, preventing rainwater or foreign objects from entering the interior of the cylinder 1. A handle is provided on the maintenance cover 2, away from the hinge, allowing the maintenance cover 2 to be opened.

For example, any of the claimed embodiments in the claims of this application can be used in any combination.

[0041] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
