Description

Technical Field

[0001] This utility model relates to the field of prefabricated pumping station technology, specifically to an integrated prefabricated pumping station. Background Technology

[0002] Integrated prefabricated pumping stations are common equipment that uses sewage pumps to provide potential and pressure energy to water, solving the problems of irrigation and sewage discharge in the absence of gravity flow. Generally, sewage is directly fed into the integrated prefabricated pumping station and then pumped out by the sewage pump. A search revealed Chinese patent CN215977639U, which discloses the technical field of integrated prefabricated pumping stations. The inlet is equipped with a maintenance valve, including a handwheel that extends out from the maintenance platform and is positioned above it. A guide rod is provided between the support and the safety port, with both ends of the guide rod connected to the support and the safety port respectively. Guide rods pass through both sides of the grating, and the grating and guide rods are detachable. A hook is provided on the inner side of the top of the cylinder, located above the grating and between the maintenance port and the safety port. The ladder is a long ladder, with one end located at the maintenance port and the other end extending to the bottom of the cylinder. An inspection valve is installed at the inlet to ensure the safety of maintenance personnel when they go down into the well to repair equipment. This effectively prevents sewage from entering the cylinder, allowing the pump station to function as both a gate well and a drainage well, reducing investment costs, shortening the construction and maintenance cycle, and improving maintenance efficiency.

[0003] The existing technologies have the following shortcomings: While wastewater can pass through the screen to filter larger debris, the sludge mixed in the water flows directly into the cylinder, easily settling on the bottom of the inner wall. This makes cleaning difficult and requires manual lifting. Furthermore, it is difficult to detect the accumulation of impurities on the screen in a timely manner. Therefore, an integrated prefabricated pumping station is provided to solve these problems. Utility Model Content

[0004] To address the problems mentioned in the background art, the technical solution adopted by this utility model is: an integrated prefabricated pumping station, comprising: a cylindrical body, a pump frame fixedly connected to the bottom of the inner part of the cylindrical body, a first water pump, a second water pump, and a third water pump fixedly connected to one side of the pump frame by bolts, a first pipe connected to the outlet end of the first water pump, a second pipe connected to the outlet end of the second water pump, and a third pipe connected to the outlet end of the third water pump, an annular pipe connected to the lower end of the first pipe, an inclined nozzle provided in the inner circle of the annular pipe, a water inlet provided on one side of the lower end of the cylindrical body, a limiting seat provided inside the cylindrical body on one side of the water inlet, a grid support plate fixedly connected to the lower end of the limiting seat, and a pressure sensor provided at the top center of the grid support plate.

[0005] As a preferred technical solution of this utility model, guide rods are fixedly connected to both sides of the top of the grid support plate, and the grid support plate is longitudinally slidably connected to the basket grid through the guide rods.

[0006] As a preferred technical solution of this utility model, a one-way solenoid valve is provided on one side of the upper end of the first pipe, the second pipe and the third pipe, and the water outlet end of the first pipe, the second pipe and the third pipe is connected to the water outlet pipe, and one end of the water outlet pipe is connected to one side of the upper end of the cylinder.

[0007] As a preferred embodiment of this utility model, the bottom side of the inner cavity of the cylinder is an inner groove, the annular tube is fixedly connected to the bottom side of the inner cavity of the cylinder, and a number of inclined nozzles are provided, with the water outlet of the inclined nozzles facing the bottom side of the inner cavity of the cylinder.

[0008] As a preferred technical solution of this utility model, the top of the cylinder is installed on a control cabinet, and the control cabinet is connected to a pressure sensor, a first water pump, a second water pump and a third water pump through wires.

[0009] As a preferred technical solution of this utility model, the top of the cylinder has an opening on the side facing the basket grid, and the top of the basket grid is connected to a steel wire rope.

[0010] The present invention has the following advantages: part of the water pumped by the first water pump flows to the main outlet pipe through the first pipe, and the other part of the water enters the annular pipe through the pipe. The water entering the annular pipe continuously flows out from the inclined nozzle, thereby causing the water at the bottom of the cylinder to continuously surge towards the middle, thus effectively avoiding the situation where sewage sludge settles at the bottom of the cylinder, and allowing the sludge mixed in the water to be continuously transported out by the water pump. When too many impurities are collected in the basket grille, the pressure sensor is pressed down, and the pressure sensor transmits the pressure data to the control cabinet in real time, so that personnel can promptly detect and clean the basket grille.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] Please refer to the following: Figures 1-4 This utility model relates to an integrated prefabricated pumping station, comprising: a cylindrical body 1, with a pump frame 2 fixedly connected to the bottom of the cylindrical body 1; a first pump 3, a second pump 4, and a third pump 5 fixedly connected to one side of the pump frame 2 via bolts; a first pipe 6 connected to the outlet of the first pump 3; a second pipe 7 connected to the outlet of the second pump 4; and a third pipe 8 connected to the outlet of the third pump 5; an annular pipe 9 connected to the lower end of the first pipe 6; an inclined nozzle 10 disposed within the inner ring of the annular pipe 9; a water inlet 12 disposed on one side of the lower end of the cylindrical body 1; a limiting seat 13 disposed inside the cylindrical body 1 on one side of the water inlet 12; a grid support plate 14 fixedly connected to the lower end of the limiting seat 13; and a pressure sensor 15 disposed at the top center of the grid support plate 14. The pressure sensor 15 is a Consensic CPS135B waterproof type.

[0017] The top two sides of the grid support plate 14 are fixedly connected to guide rods 16. The grid support plate 14 is longitudinally slidably connected to the basket grid 17 through the guide rods 16. The basket grid 17 can be lifted and lowered by dragging the steel wire rope, so that the basket grid 17 moves up and down along the guide rods 16. One-way solenoid valves 11 are installed on one side of the upper end of the first pipe 6, the second pipe 7, and the third pipe 8, so as to effectively prevent water backflow in the outlet pipe 19. The outlet ends of the first pipe 6, the second pipe 7, and the third pipe 8 are connected to the outlet pipe 19. One end of the outlet pipe 19 is connected to one side of the upper end of the cylinder 1. The bottom side of the inside of the cylinder 1 is an inner groove, and the annular pipe 9 is fixedly connected. Several inclined nozzles 10 are provided on the bottom side inside the cylinder 1. The water outlet of the inclined nozzles 10 is directly facing the bottom side inside the cylinder 1. The multiple inclined nozzles 10 can make the sewage inside the cylinder 1 form a vortex flow, which makes it easier for sludge and other impurities in the sewage to be located in the middle of the vortex and easily pumped out by the water pump. The top of the cylinder 1 is installed on the control cabinet 18. The control cabinet 18 is connected to the pressure sensor 15, the first water pump 3, the second water pump 4 and the third water pump 5 through wires. The control cabinet 18 is also remotely connected to the terminal equipment in the control room. An opening 20 is preset on the side of the top of the cylinder 1 facing the basket grille 17. A steel wire rope is connected to the top of the basket grille 17.

[0018] Specifically, in use, wastewater enters through inlet 12, passes through basket screen 17 to filter out larger impurities, and then flows into cylinder 1. The first pump 3 is activated, and simultaneously the second pump 4 or the third pump 5 (one in operation and one on standby) is also activated. The corresponding one-way solenoid valve 11 on the pumping pipeline is opened, causing part of the water pumped by the first pump 3 to flow through the first pipe 6 to the main outlet pipe 19, while the other part enters the annular pipe 9 through a pipe. The water inside the annular pipe 9 continuously flows out from the inclined nozzle 10. This causes the water at the bottom of the cylinder 1 to continuously flow towards the middle, effectively preventing the sludge from settling at the bottom of the cylinder 1. The sludge mixed in the water can be continuously transported out by the water pump. When too many impurities are filtered and collected in the basket grille 17, the overall weight increases, which in turn increases the pressure of the pressure sensor 15. The pressure sensor 15 then transmits the pressure data to the control cabinet 18 in real time. If the pressure exceeds the set range, an alarm is triggered, indicating that too much debris has been collected inside the basket grille 17 and it needs to be cleaned.

[0019] The above are merely preferred embodiments of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.

[0020] All other parts of this utility model that are not described in detail belong to the prior art, and therefore will not be described in detail here.

[0021] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
