Technical Field

[0001] This utility model relates to the field of integrated pump station technology, specifically an integrated pump station with sedimentation and cleaning function. Background Technology

[0002] An integrated prefabricated pumping station is a complete set of equipment that is pre-manufactured and assembled in a factory. It achieves the functions of irrigation, drainage, water supply and water resource allocation of traditional pumping stations through overall transportation and installation.

[0003] The sewage treated by the pumping station contains impurities. Due to gravity, these impurities often accumulate at the bottom of the cylinder, which can easily cause foul odors or even damage the pumping station over time. Therefore, workers need to clean and maintain the pumping station regularly, which increases labor and costs. In order to clean the sediment in a timely manner, this application designs an integrated pumping station with sedimentation and cleaning functions to solve this technical defect. Utility Model Content

[0007] The dredging lifting cylinder has a sealed sliding movable lifting plate inside, and a sewage pipe is connected to the outside of the dredging lifting cylinder;

[0008] The dredging lifting cylinder is equipped with a lifting component for lifting and moving the movable lifting plate.

[0009] Using the above technical solution, after the sewage is pumped out by the internal lift pump of the GRP pump station cylinder, the sediment settles into the tank and is discharged into the sludge lifting cylinder through the connecting pipe. When cleaning the sediment in the sludge lifting cylinder, the opening at the connection between the GRP pump station cylinder and the connecting pipe is sealed by the switch assembly, and then the lifting assembly lifts the moving lifting plate to move upwards in the sludge lifting cylinder. During the movement, the stored sediment moves upwards synchronously. When it moves to the sewage pipe, the sediment can be discharged from the sewage pipe.

[0010] The cleaning component removes sediment buildup in the tank, preventing blockages.

[0011] As a preferred embodiment of this utility model, the upper end of the mounting base is provided with a device mounting tray frame.

[0012] Using the above technical solution, the equipment installation mesh frame enables the installation and assembly of equipment such as booster pumps inside the GRP pump station cylinder.

[0013] As a preferred technical solution of this utility model, the cleaning component includes a hydraulic push rod 1 located outside the GRP pump station cylinder. The push rod of the hydraulic push rod 1 passes through the GRP pump station cylinder and is located at the scraper of the collection groove. The scraper is tightly fitted with the mounting base. Sealing arc plates are provided on both the left and right sides of the scraper, and the sealing arc plates seal the opening of the connecting pipe.

[0014] Using the above technical solution, the scraper and sealing arc plate are moved by the hydraulic push rod to clean the sediment attached to the tank, thus avoiding blockage caused by not cleaning for a long time.

[0015] As a preferred technical solution of this utility model, the switch assembly includes a hydraulic push rod II located at the lower end of the dredging lifting cylinder. The push rod of the hydraulic push rod II passes through into the dredging lifting cylinder, and a sealing seat is provided at the push rod to seal and fit with the inside of the dredging lifting cylinder.

[0016] As a preferred technical solution of this utility model, when the push rod of the hydraulic push rod II is in a fully extended state, the sealing seat seals the connection between the connecting pipe and the dredging lifting cylinder.

[0017] Using the above technical solution, the hydraulic pusher two pushes the sealing seat to move within the dredging lifting cylinder to the connecting pipe, thereby sealing the connection between the connecting pipe and the dredging lifting cylinder.

[0018] As a preferred embodiment of this utility model, the movable lifting plate and the sealing seat have the same diameter, and the diameter of the movable lifting plate is equal to the inner diameter of the dredging lifting cylinder;

[0019] The movable lifting plate is located above the sealing seat.

[0020] By adopting the above technical solution, the sealing fit between the movable lifting plate and the sealing seat and the dredging lifting cylinder is guaranteed.

A winding reel is provided at the center of the outer side of the rotating shaft. A pull rope is wound and fixed on the outer side of the winding reel. The other end of the pull rope is connected to the center of the movable lifting plate.

[0022] Using the above technical solution, the drive motor drives the winding reel on the rotating shaft to rotate, thereby winding and unwinding the rope, which in turn pulls the moving lifting disc to move up and down inside the dredging lifting cylinder.

[0023] As a preferred embodiment of this utility model, the upper end of the movable lifting plate has multiple counterweights at equal intervals in a ring.

[0024] Using the above technical solution, the counterweight blocks counterbalance the moving lifting plate, so that the counterweight blocks can move stably downward inside the dredging lifting cylinder under the action of the counterweight gravity.

[0025] As a preferred technical solution of this utility model, the sealing seat is provided with an air hole, and the bottom of the dredging lifting cylinder is provided with an exhaust hole.

[0026] By adopting the above technical solution, it is convenient to discharge the compressed gas through the air hole and exhaust hole when the moving lifting plate moves down.

[0027] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0028] This integrated pump station with sedimentation and cleaning function uses an internal lift pump to pump out sewage. The sediment settles in a tank and is discharged into a sludge lifting cylinder through a connecting pipe. When cleaning the sediment in the sludge lifting cylinder, the opening at the connection between the GRP pump station cylinder and the connecting pipe is sealed by a switch assembly. Then, the lifting assembly lifts the moving lifting plate and moves it upwards within the sludge lifting cylinder. During the movement, the stored sediment moves upwards synchronously. When it reaches the sewage pipe, the sediment is discharged from the sewage pipe.

[0029] The cleaning component removes sediment buildup in the tank, preventing blockages and eliminating the need for regular manual cleaning compared to existing technologies, thus achieving automated cleaning. Attached Figure Description

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1 to 6 The integrated pump station with sedimentation and cleaning function in this embodiment mainly includes a GRP pump station cylinder 1, a mounting base 2, a connecting pipe 3, a sludge lifting cylinder 4, a collection trough 5, a cleaning component, a switch component, a movable lifting plate 11, a lifting component, and a sewage pipe 19.

[0039] The GRP pump station cylinder 1 is made of fiberglass (GRP) material, which has the advantages of high strength and corrosion resistance. It is the main housing structure of the entire pump station. The mounting base 2 is fixedly set at the bottom of the lower end of the GRP pump station cylinder 1 and is set at the same center. It provides the installation foundation for other components of the pump station. The upper end of the mounting base 2 is provided with a rectangular collection trough 5 for collecting sediment in sewage.

[0040] Furthermore, the lower end of the GRP pump station cylinder 1 is provided with a water inlet connector, and the inside of the GRP pump station cylinder 1 is provided with a gate valve that controls the opening and closing of the water inlet connector. A crushing screen is connected to the gate valve to crush impurities entering the water. The upper external end of the GRP pump station cylinder 1 is provided with a drain connector that connects to the drain outlet of the internal booster pump. The upper end of the GRP pump station cylinder 1 is also provided with a control box and maintenance window. The lower end of the mounting base is provided with mounting holes, and it is installed on the mounting carrier by bolts.

[0041] The mounting base 2 is externally connected to two connecting pipes 3. One end of the connecting pipe 3 is connected to the collection tank 5, and the other end is connected to the sludge lifting cylinder 4, so as to realize the transfer of sediment from the collection tank 5 to the sludge lifting cylinder 4.

[0042] The dredging lifting cylinder 4 has a cylindrical structure, and a movable lifting plate 11 is installed inside it in a sealed sliding manner. The diameter of the movable lifting plate 11 is equal to the inner diameter of the dredging lifting cylinder 4 to ensure the sealing effect. The upper outer side of the dredging lifting cylinder 4 is connected to a sewage pipe 19 for discharging the cleaned sediment.

[0043] The cleaning assembly is installed on the GRP pump station cylinder 1 and is used to clean the sludge collected in the tank 5. Specifically, it includes a hydraulic push rod 6, a scraper 7, and a sealing arc plate 8. The hydraulic push rod 6 is fixedly installed on the outside of the GRP pump station cylinder 1. Its push rod passes through the GRP pump station cylinder 1 and extends into the tank 5. The scraper 7 is fixedly connected to the push rod end of the hydraulic push rod 6 and fits tightly with the mounting base 2. It can move in the tank 5 under the push of the hydraulic push rod 6 to scrape off the sediment attached to the mounting base 2. The left and right sides of the scraper 7 are fixed with sealing arc plates 8. The shape of the sealing arc plate 8 is adapted to the opening of the connecting pipe 3, and can seal the opening of the connecting pipe 3 when the scraper 7 moves.

[0044] A switch assembly is installed on the dredging lifting cylinder 4 to control the opening at the connection between the connecting pipe 3 and the dredging lifting cylinder 4. Specifically, it includes a hydraulic push rod 2 9 and a sealing seat 10. The hydraulic push rod 2 9 is fixedly installed at the bottom of the lower end of the dredging lifting cylinder 4, with its push rod passing through the dredging lifting cylinder 4 and extending into the interior. The sealing seat 10 is fixedly connected to the end of the push rod of the hydraulic push rod 2 9 and is sealed and fitted inside the dredging lifting cylinder 4. When the push rod of the hydraulic push rod 2 9 is in the fully extended state, the sealing seat 10 can seal the connection between the connecting pipe 3 and the dredging lifting cylinder 4, preventing the sediment in the dredging lifting cylinder 4 from flowing back into the collection tank 5 when cleaning sediment. In addition, the sealing seat 10 is provided with an air hole, and the bottom of the dredging lifting cylinder 4 is provided with an exhaust hole, so that the compressed gas can be discharged through the air hole and the exhaust hole when the moving lifting plate 11 moves down, ensuring the smooth downward movement of the moving lifting plate 11.

[0045] It should be noted that the movable lifting plate 11 and the sealing seat 10 have the same diameter.

[0046] The lifting assembly is mounted on the dredging lifting cylinder 4 and is used to lift and move the movable lifting plate 11. Specifically, it includes a mounting frame 12, a drive motor 13, a rotating shaft 14, a winding reel 15, and a pull rope 16. The mounting frame 12 is fixedly mounted on the upper surface of the dredging lifting cylinder 4 to provide mounting support for other components. The drive motor 13 is fixedly mounted on the left side of the mounting frame 12, and its output end is connected and fixed to the rotating shaft 14 to drive the rotating shaft 14 to rotate. The rotating shaft 14 is connected to the inner side of the mounting frame 12 through a bearing to rotate. The winding reel 15 is arranged concentrically on its outer side. The pull rope 16 is wound and fixed on the outside of the winding reel 15, and its other end is connected to the center of the movable lifting plate 11. When the drive motor 13 starts, it drives the rotating shaft 14 and the winding reel 15 to rotate, realizing the winding and unwinding of the pull rope 16, thereby pulling the movable lifting plate 11 to move up and down inside the dredging lifting cylinder 4.

[0047] The lower end of the dredging lifting cylinder 4 has a fastening hole. Bolts are passed through the fastening hole to install the dredging lifting cylinder 4 onto the mounting carrier.

[0048] The upper surface of the mounting base 2 is also fixed with an equipment mounting mesh tray 18. The equipment mounting mesh tray 18 is made of metal material and has high strength and stability. It is used to install and assemble equipment such as lifting pumps inside the GRP pump station cylinder 1. Multiple counterweights 17 are fixed at equal intervals in a ring at the upper end of the movable lifting plate 11. In this application, there are 6 counterweights 17. The number can be increased or decreased according to the actual situation. The counterweights 17 are made of high-density material, such as cast iron, and are used to counterweight the movable lifting plate 11 so that the movable lifting plate 11 can move stably downward inside the dredging lifting cylinder 4 under the action of the counterweight gravity.

[0049] Structural design principles and usage steps:

[0050] During the sediment collection stage,

[0051] After the lifting pump inside the GRP pump station cylinder 1 pumps out the sewage, the sediment in the sewage settles into the tank 5 due to gravity. As the sewage is continuously treated, the sediment in the tank 5 gradually increases and is discharged into the sludge lifting cylinder 4 through the connecting pipe 3 and stored in the space below the movable lifting plate 11.

[0052] Cleanup and preparation phase

[0053] When it is necessary to clean the sediment in the dredging lifting cylinder 4, first activate the hydraulic push rod 2 9 to extend it and push the sealing seat 10 to move upward and seal inside the dredging lifting cylinder 4 until the sealing seat 10 seals the connection between the connecting pipe 3 and the dredging lifting cylinder 4, preventing the sediment from flowing back during the cleaning process.

[0054] During the sedimentation stage,

[0055] Start the drive motor 13, which drives the rotating shaft 14 and the winding reel 15 to rotate and wind up the pull rope 16, causing the movable lifting plate 11 to move upward in a sealed manner inside the dredging lifting cylinder 4. During the upward movement of the movable lifting plate 11, the stored sediment moves upward synchronously. Since the movable lifting plate 11 is sealed and fitted with the dredging lifting cylinder 4, the sediment will not leak back to the bottom of the dredging lifting cylinder 4.

[0056] During the sediment discharge stage,

[0057] When the movable lifting plate 11 moves to the drain pipe 19, the sediment is discharged from the drain pipe 19 under the action of gravity, thus cleaning up the sediment.

[0058] Collected in the cleaning stage of tank 5,

[0059] After the sediment in the dredging lifting cylinder 4 is cleaned, the moving lifting plate 11 is lowered and reset. At the same time, compressed gas is discharged from the air hole and exhaust hole. The hydraulic push rod 6 is activated. The hydraulic push rod 6 pushes the scraper 7 and the sealing arc plate 8 to move in the collection trough 5, scraping off the sediment attached to the mounting base 2 and pushing the sediment into the connecting pipe 3, and then into the dredging lifting cylinder 4, to avoid the sediment in the collection trough 5 from clogging.

[0060] GRP pump station cylinder 1: Made of fiberglass (GRP) material, it has the advantages of high strength, corrosion resistance, and light weight, and can adapt to various harsh environmental conditions.

[0061] Mounting base 2, connecting pipe 3, and dredging lifting cylinder 4: Made of stainless steel, they have good corrosion resistance and strength, ensuring long-term stable operation of the pump station.

[0062] Scraper 7, sealing arc plate 8, sealing seat 10, and movable lifting plate 11: Made of sealing materials such as rubber or polytetrafluoroethylene, they have good sealing performance and can effectively prevent the leakage of sediment.

[0063] Hydraulic push rod 16 and hydraulic push rod 29: They adopt a hydraulic drive method and have the advantages of large thrust and smooth operation, which can meet the power requirements of cleaning components and switching components.

[0064] Drive motor 13: It adopts an AC motor, which has the advantages of high power and stable speed, and can provide sufficient power for the lifting components.

[0065] Pull rope 16: Made of high-strength steel wire rope, it has the advantages of strong load-bearing capacity and good wear resistance, which can ensure the stable lifting of the mobile lifting plate 11.

[0066] Counterweight 17: Made of cast iron, it has the advantages of high density and heavy weight, and can provide sufficient counterweight for the moving lifting plate 11.

[0067] Control cabinet: It adopts a programmable logic controller (PLC), which has the advantages of flexible programming, high reliability and strong anti-interference ability, and can accurately control various components of the pump station.

[0068] Through the above system control expansion, this integrated pump station with sedimentation and cleaning function can realize the automatic collection, automatic cleaning and automatic discharge of sediment, which greatly improves the operating efficiency and reliability of the pump station and reduces manual maintenance costs.

[0069] All electrical components mentioned in the text are electrically connected to the main controller and power supply. The main controller can be a conventional and known device such as a computer, and the existing publicly available power connection technology will not be elaborated in the text.

[0070] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
