Description

Technical Field

[0001] The present application relates to the technical field of prefabricated pumping stations, and in particular to a prefabricated sewage pumping station. Background Art

[0002] Prefabricated sewage pumping stations are modular, integrated drainage facilities designed to collect, lift, and transport domestic sewage, industrial wastewater, and rainwater. Prefabricated in factories and quickly installed on-site, these pumping stations offer a short construction period and minimal footprint, making them suitable for municipal pipe networks, industrial parks, and rural sewage treatment.

[0003] At present, prefabricated sewage pumping stations consist of a cylinder, a submersible pump group, a screen system (basket screen or crushing screen) and an intelligent control unit. During use, sewage flows into the pumping station through the pipeline, is filtered by the screen system and temporarily stored in the cylinder. When the water level reaches the threshold, the intelligent control unit controls the submersible pump group to start and pressurize the sewage to the pipeline network or treatment plant.

[0004] When using the basket grille for filtering, when there are a lot of debris intercepted in the basket grille, it is necessary to manually lift the basket grille upward through the track chain, then take out the basket grille and clean the debris in the basket grille. This method is not convenient for cleaning the basket grille.

[0005] When a large amount of debris accumulates within a traditional basket screen, manual chain hoisting is required to hoist the entire screen to a ground platform, where it is then disassembled and cleared of the debris. This process of hoisting, disassembling, cleaning, and resetting the basket screen is limited by low efficiency. Summary of the Invention

[0006] In order to improve the cleaning efficiency of the basket grille, the present application provides a prefabricated sewage pumping station.

[0007] The prefabricated sewage pumping station provided in this application adopts the following technical solution: A prefabricated sewage pumping station, comprising a cylinder body, an inlet pipe and an outlet pipe are arranged on the cylinder body, a submersible pump group is arranged in the cylinder body, a basket grille is arranged at the inlet pipe in the cylinder body, a grille outlet is opened at the top end of the cylinder body, an outlet cover is arranged on the cylinder body at the grille outlet, a track is arranged in the cylinder body below the grille outlet, a lifting seat is slidably arranged on the track in the vertical direction, a driving mechanism for driving the lifting seat to lift and move is arranged on the cylinder body at the grille outlet, the basket grille is rotatably arranged in the lifting seat, a first locking mechanism for locking the basket grille is arranged in the lifting seat, a sewage discharge port is arranged at the bottom of the basket grille, a sewage discharge plate is rotatably arranged at the sewage discharge port of the basket grille, a second locking mechanism is arranged in the lifting seat, the second locking mechanism is located below the sewage discharge plate and is used for abutting and closing the sewage discharge plate, an unlocking block is arranged at the top end of the track at the grille outlet, when the lifting seat rises to the grille outlet, the unlocking block unlocks the first locking mechanism, the basket grille is rotated on the lifting seat, when the basket grille drives the sewage discharge plate to rotate away from the second locking mechanism, the sewage discharge plate rotates and opens the sewage discharge port.

[0008] By adopting the above technical solutions, when it is necessary to clean the basket grille, the outlet cover is opened, and the driving mechanism is used to drive the lifting seat to rise and move in the track. When the lifting seat rises to the grille outlet, the basket grille moves outside the grille outlet. At this time, the unlocking block unlocks the first locking mechanism, so that the basket grille can rotate in the lifting seat. Then the basket grille is rotated, and the basket grille drives the sewage discharge plate to rotate. During the rotation of the sewage discharge plate, the second locking mechanism abuts against the sewage discharge plate, so that the sewage discharge plate will not rotate. As the basket grille rotates continuously, when the sewage discharge plate is separated from the second locking mechanism, the sewage discharge plate rotates under the action of gravity, so that the sewage discharge port at the bottom of the basket grille is opened, and the sundries in the basket grille can be discharged from the sewage discharge port. With such a setting, when cleaning the sundries in the basket grille, there is no need to disassemble and assemble the basket grille, thereby improving the cleaning efficiency of the basket grille.

The second elastic member is arranged in the lifting seat and is used to push the pull plate to move back to its original position. When the lifting seat rises to the grille outlet, the unlocking block pushes the pull block to move. The pull block drives the plug pin to slide out of the slot through the pull plate and the pull rope. When the lifting seat descends into the cylinder body, the unlocking block is separated from the pull block, the second elastic member pushes the pull plate to move back to its original position, and the first elastic member pushes the plug pin into the slot.

[0010] By adopting the above technical solution, when the basket grille filters sewage, the first elastic member pushes the bolt into the slot and limits the rotation shaft, so that the basket grille will not rotate; when the lifting seat rises to the grille outlet, the unlocking block pushes the pulling block to move, and the pulling block drives the bolt to move away from the rotation shaft through the pulling plate and the pulling rope. After the bolt slides out of the slot, the limit on the rotation shaft can be released, and then the basket grille can be rotated; when the lifting seat descends into the cylinder body, the unlocking block is separated from the pulling block, the second elastic member pushes the pulling plate to move back to its original position, and the first elastic member pushes the bolt into the slot, so as to lock the rotation shaft again.

A lifting groove is formed on the top wall of the push rod. Chamfers are formed at one ends of the lifting groove and the top rod close to each other. Chamfers are formed at the ends of the push rod and the trigger block close to each other. The fifth elastic member is arranged in the lifting seat and is used to push the push rod to move back to its original position. When the lifting seat rises to the grille outlet, the unlocking block pushes the push rod to move, the bottom end of the top rod enters the lifting groove, the top rod descends and releases the lock on the basket grille. When the lifting seat descends into the cylinder body, the unlocking block is separated from the push rod, the fifth elastic member pushes the push rod to move back to its original position, the push rod drives the top rod to rise through the lifting groove, the bottom end of the top rod abuts against the push rod, and the top end of the top rod abuts against the bottom of the basket grille to lock the basket grille.

[0012] By adopting the above technical solution, when the basket grille filters sewage, the top end of the top rod abuts tightly against the bottom of the basket grille, so that the basket grille will not rotate; when the lifting seat rises to the grille outlet, the unlocking block pushes the push rod to move, the bottom end of the top rod enters the lifting groove, the top rod descends and releases the lock on the basket grille; when the lifting seat descends into the cylinder body, the unlocking block is separated from the push rod, the fifth elastic member pushes the push rod to move back to its original position, the push rod drives the top rod to rise through the lifting groove, the bottom end of the top rod abuts against the push rod, and the top end of the top rod abuts against the bottom of the basket grille to lock the basket grille.

[0014] By adopting the above technical solution, the third elastic member pushes the first roller upward through the lifting rod, and the first roller moves and abuts against the bottom wall of the sewage discharge plate, so as to be able to close the sewage discharge port; when the basket grille starts to rotate, the third elastic member acts on the lifting rod, and the lifting and lowering movement of the lifting rod enables the first roller to always abut tightly against the sewage discharge plate, so that sundries will not leak during the initial rotation process of the basket grille; when the basket grille rotates to a certain angle, the sewage discharge plate and the first roller move away from each other, and at this time, the sewage discharge plate rotates under the action of gravity and opens the sewage discharge port; after the sundries are cleaned up, the basket grille is rotated back to its original position, and the first roller abuts against the sewage discharge plate again to close the sewage discharge port.

[0015] Preferably, the driving mechanism includes a driving member, a winding drum, two cables and guide wheels. Lifting lugs are fixedly arranged on the bottom walls of the opposite side walls of the lifting seat.

Detailed implementation manners

[0026] The following further elaborates on the present application in conjunction with the attached Figures 1 - 10 for a more detailed description.

[0027] Embodiment 1 of the present application discloses a prefabricated sewage pumping station.

[0028] Embodiment 1: Referring to Figure 1 and Figure 2 , a prefabricated sewage pumping station includes a cylinder body 1. A grille outlet 9 and an inspection opening 24 are formed at the top of the cylinder body 1. An outlet cover 10 is installed on the top of the cylinder body 1 at the grille outlet 9, and an inspection cover 25 is installed at the inspection opening 24 on the top of the cylinder body 1. The inlet pipe 2 and the outlet pipe 3 are respectively installed on both sides of the outer wall of the cylinder body 1, and the height of the inlet pipe 2 is greater than the height of the outlet pipe 3.

[0029] Referring to Figure 3 and Figure 4, a submersible pump set 4 is installed inside the cylinder body 1. The water inlet end of the submersible pump set 4 is located at the bottom of the inner cavity of the cylinder body 1, and the water outlet pipe 3 of the submersible pump set 4 is connected to the water outlet pipe 3. On one side of the inner side wall of the cylinder body 1 close to the water inlet pipe 2, a track 11 is fixedly installed. An elevator seat 12 is slidably installed in the track 11 in the vertical direction, and the cross-section of the elevator seat 12 is in a U shape. A basket grille 8 is rotatably installed in the elevator seat 12 through a rotating shaft 16. The basket grille 8 is located at the water inlet of the water inlet pipe 2, and the basket grille 8 is directly below the grille outlet 9.

[0030] Referring to Figure 2 and Figure 4 , a driving mechanism 5 is installed at the grille outlet 9 of the cylinder body 1. The driving mechanism 5 includes a driving part 51, a winding drum 52, two cable wires 53 and a guide wheel 54. The driving part 51 is fixedly installed on the cylinder body 1, the winding drum 52 is rotatably installed on the cylinder body 1, and the two cable wires 53 are respectively wound and installed at both ends in the length direction of the winding drum 52. In this application, the driving part 51 can be selected as a servo motor, and the driving end of the driving part 51 is connected to the winding drum 52.

[0031] At the bottom of the opposite side walls of the elevator seat 12, two lifting lugs 19 are symmetrically and fixedly installed. The two guide wheels 54 are rotatably installed at the top of the opposite side walls of the track 11. The two guide wheels 54 are respectively directly above the two lifting lugs 19, and the two cable wires 53 pass through the two guide wheels 54 and are connected to the two lifting lugs 19.

[0032] The driving part 51 drives the winding drum 52 to rotate. During the rotation of the winding drum 52, the cable wire 53 is wound up. The cable wire 53 drives the elevator seat 12 to rise through the lifting lug 19, and the elevator seat 12 then drives the basket grille 8 to rise to the grille outlet 9, so as to facilitate the cleaning of the basket grille 8. When the winding drum 52 rotates in the reverse direction, the basket grille 8 can be driven to descend and reset.

[0033] Referring to Figure 4 and Figure 5 , a plurality of sliders 21 are slidably installed on the outer side wall of the elevator seat 12. A plurality of fourth elastic members 22 are installed in the elevator seat 12. The plurality of fourth elastic members 22 correspond to the plurality of sliders 21 one by one and push the sliders 21 to slide away from the elevator seat 12. A second roller 20 is rotatably installed on each slider 21, and the second roller 20 abuts against the inner side wall of the track 11. In this application, the fourth elastic member 22 can be selected as a spring.

[0034] During the lifting movement of the elevator seat 12, the elevator seat 12 drives the second roller 20 to move. The second roller 20 contacts the inner wall of the track 11, reducing the friction between the elevator seat 12 and the track 11 and facilitating the smooth lifting movement of the basket grille 8. When there are sundries in the track 11, under the action of the fourth elastic member 22, the second roller 20 can push the slider 21 to move into the elevator seat 12, making the movement of the elevator seat 12 not easily blocked.

[0035] Refer to Figure 2 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown in, a first locking mechanism 6 is installed inside the lifting seat 12. The first locking mechanism 6 locks the rotating shaft 16, and further locks the basket grille 8, so that the basket grille 8 will not rotate during the process of filtering debris. A sewage outlet 13 is formed at the bottom of the basket grille 8. A sewage discharge plate 14 is rotatably installed at the sewage outlet 13 of the basket grille 8. The hinge point of the sewage discharge plate 14 is located on the side away from the water inlet pipe 2 of itself. A second locking mechanism 7 is installed inside the lifting seat 12. The second locking mechanism 7 locks the sewage discharge plate 14 in the closed state.

[0036] An unlocking block 15 is fixedly installed on the inner side wall of the top end of the track 11. When the driving mechanism 5 drives the lifting seat 12 to rise to the grille outlet 9, the basket grille 8 rises above the grille outlet 9. At this time, the unlocking block 15 unlocks the first locking mechanism 6, and the basket grille 8 is rotated on the lifting seat 12. When the basket grille 8 drives the sewage discharge plate 14 to rotate away from the second locking mechanism 7, the sewage discharge plate 14 rotates under the action of gravity and opens the sewage outlet 13. Place the trash can at the sewage outlet 13 of the basket grille 8, and the debris in the basket grille 8 can be discharged from the sewage outlet 13 without disassembling and assembling the basket grille 8, thereby improving the cleaning efficiency of the basket grille 8.

[0037] Refer to Figure 2 、 Figure 4 and Figure 5 As shown in, two first locking mechanisms 6 and two unlocking blocks 15 are installed. The two first locking mechanisms 6 are installed on both sides of the lifting seat 12, and the two unlocking blocks 15 are installed on the opposite inner side walls of the track 11 and correspond to the two first locking mechanisms 6. The first locking mechanism 6 includes a bolt 601, a pull rope 602, a pull block 603, a pull plate 604, a first elastic member 605 and a second elastic member 606. The bolt 601 is slidably installed horizontally inside the lifting seat 12. A slot 17 is formed in the side wall of the rotating shaft 16 along its radial direction. The first elastic member 605 is installed inside the lifting seat 12 on the side of the bolt 601 away from the slot 17. In this application, the first elastic member 605 can be selected as a spring. The first elastic member 605 pushes the bolt 601 into the slot 17, and the bolt 601 locks the rotating shaft 16 through the slot 17, so as to lock the rotation of the basket grille 8.

[0038] The pull plate 604 is slidably installed horizontally in the lifting seat 12 and is located below the bolt 601. The pull block 603 is fixedly installed on the side wall of the pull plate 604, and one end of the pull block 603 away from the pull plate 604 is located inside the lifting seat 12. The pull rope 602 is installed inside the lifting seat 12. The two ends of the pull rope 602 are respectively connected to the ends of the bolt 601 and the pull plate 604. The second elastic member 606 is installed inside the lifting seat 12, and the second elastic member 606 abuts against the end of the pull plate 604 away from the pull rope 602. Chamfers are formed at the tops of both the pull block 603 and the unlocking block 15.

[0039] When the lifting seat 12 rises to the grille outlet 9, the lifting seat 12 drives the pull block 603 to move and contact the unlocking block 15. Under the action of the chamfers of the pull block 603 and the unlocking block 15, the unlocking block 15 pushes the pull block 603 to move horizontally. The pull block 603 drives the bolt 601 to move away from the rotating shaft 16 through the pull plate 604 and the pull rope 602. The bolt 601 disengages from the slot 17 and releases the locking of the rotating shaft 16. The pull plate 604 squeezes the second elastic member 606 and deforms it. The bolt 601 squeezes the first elastic member 605 and deforms it.

[0040] After the sundries in the basket grille 8 are cleaned up, the lifting seat 12 descends into the cylinder body 1. The unlocking block 15 separates from the pull block 603. The second elastic member 606 pushes the pull plate 604 to move back to its original position. The first elastic member 605 pushes the bolt 601 to re-insert into the slot 17, so that the rotating shaft 16 can be locked again.

[0041] Refer to Figure 6 and Figure 7 As shown in, two second locking mechanisms 7 are installed. The two second locking mechanisms 7 are respectively located on both sides of the bottom of the basket grille 8 in the width direction. The second locking mechanism 7 includes a sleeve 71, a lifting rod 72, a third elastic member 73 and a first roller 74. The sleeve 71 is fixedly installed on the lifting seat 12. The lifting rod 72 is slidably installed vertically in the sleeve 71. The third elastic member 73 is installed in the sleeve 71. The top end of the third elastic member 73 abuts against the bottom end of the lifting rod 72. In this application, the third elastic member 73 can be selected as a spring. The first roller 74 is rotatably installed on the top end of the lifting rod 72. The first roller 74 abuts against the bottom wall of the sewage discharge plate 14 and is located on one side close to the inner wall of the cylinder body 1.

[0042] During the process of the basket grille 8 filtering debris, the third elastic member 73 pushes the first roller 74 against the bottom wall of the sewage discharge plate 14 through the lifting rod 72, thereby locking the sewage discharge plate 14 and preventing the sewage discharge plate 14 from rotating and opening. At the beginning of the rotation of the basket grille 8, the basket grille 8 drives the sewage discharge plate 14 to move. The third elastic member 73 acts on the lifting rod 72, and the lifting and lowering movement of the lifting rod 72 enables the first roller 74 to always press tightly against the sewage discharge plate 14, so that debris will not leak during the initial rotation of the basket grille 8.

[0043] When the basket grille 8 rotates to a certain angle, the sewage discharge plate 14 and the first roller 74 move apart. At this time, the first roller 74 no longer locks the sewage discharge plate 14, and the sewage discharge plate 14 rotates under the action of gravity and opens the sewage discharge port 13. After the debris is cleared, when the basket grille 8 is rotated back to its original position and the first roller 74 abuts against the sewage discharge plate 14 again, the first roller 74 can push the sewage discharge plate 14 to rotate in the reverse direction, thereby closing the sewage discharge port 13.

[0044] Side baffles 23 are fixedly installed at both ends of the sewage discharge plate 14 in the length direction. The side baffles 23 are perpendicular to the sewage discharge plate 14, and the two side baffles 23 are respectively located on both sides of the basket grille 8. When the sewage discharge plate 14 rotates to open the sewage discharge port 13, the two side baffles 23 are located on both sides of the sewage discharge plate 14, so as to block debris and prevent the debris from falling into the cylinder 1 from the side of the sewage discharge plate 14.

[0045] The implementation principle of a prefabricated sewage pumping station in an embodiment of the present application is as follows: Sewage flows into the pumping station through the water inlet pipe 2, is filtered by the basket grille 8 and temporarily stored in the cylinder 1. When the water level reaches the threshold, the submersible pump group 4 pressurizes the sewage and transports it to the pipe network or treatment plant through the water outlet pipe 3. When the basket grille 8 needs to be cleaned, the driving member 51 drives the reel 52 to rotate. During the rotation of the reel 52, the cable 53 is wound up. The cable 53 drives the lifting seat 12 to rise through the lifting lug 19, and the lifting seat 12 then drives the basket grille 8 to rise to the grille outlet 9. The lifting seat 12 drives the pulling block 603 to move into contact with the unlocking block 15. Under the action of the chamfers of the pulling block 603 and the unlocking block 15, the unlocking block 15 pushes the pulling block 603 to move horizontally. The pulling block 603 drives the bolt 601 to move away from the rotating shaft 16 through the pulling plate 604 and the pulling rope 602, and the bolt 601 disengages from the slot 17 and releases the lock on the rotating shaft 16. After rotating the basket grille 8, the sewage discharge plate 14 and the first roller 74 move apart. At this time, the first roller 74 no longer locks the sewage discharge plate 14, and the sewage discharge plate 14 rotates under the action of gravity and opens the sewage discharge port 13. Place a trash can at the sewage discharge port 13 of the basket grille 8, and the debris in the basket grille 8 can be discharged from the sewage discharge port 13 without disassembling and assembling the basket grille 8, thereby improving the cleaning efficiency of the basket grille 8.

[0046] Embodiment 2: Reference Figure 8 、 Figure 9 and Figure 10 In this embodiment, the difference from Embodiment 1 is that the first locking mechanism 6 includes a push rod 611, a push rod 612 and a fifth elastic member 613. The push rod 611 is slidably installed in the lifting seat 12 in the horizontal direction. One end of the push rod 611 extends out of the lifting seat 12, and a chamfer is formed at the top of the end of the push rod 611 extending out of the lifting seat 12. The fifth elastic member 613 is installed in the lifting seat 12, and the fifth elastic member 613 is located at one end of the push rod 611 away from the chamfer.

[0047] The push rod 612 is slidably installed in the lifting seat 12 in the vertical direction. A lifting groove 27 is formed in the top wall of the push rod 611. Chamfers are formed on one side of the lifting groove 27 close to the push rod 612 and at the bottom end of the push rod 612. The top end of the push rod 612 extends out of the lifting seat 12 and extends to the bottom of the basket grille 8. A third roller 26 is installed at the top end of the push rod 612. Two first rollers 74 are located at two corners of the bottom wall of the basket grille 8, and two third rollers 26 are located at the other two corners of the bottom wall of the basket grille 8.

[0048] The implementation principle of Embodiment 2 of this application is as follows: When the basket grille 8 filters sewage, the third roller 26 at the top end of the push rod 612 abuts against the bottom of the basket grille 8, and the bottom end of the push rod 612 abuts against the top wall of the push rod 611, thereby locking the basket grille 8 so that the basket grille 8 will not rotate. When the lifting seat 12 rises to the grille outlet 9, the unlocking block 15 pushes the push rod 611 to move horizontally into the lifting seat 12. The push rod 611 drives the lifting groove 27 to move below the push rod 612, and the push rod 611 moves to compress the fifth elastic member 613. The push rod 612 moves downward under the action of gravity into the lifting groove 27. At this time, the third roller 26 at the top end of the push rod 612 is separated from the bottom of the basket grille 8, thereby unlocking the basket grille 8 so that the basket grille 8 can rotate to clean debris. When the lifting seat 12 descends into the cylinder body 1, the unlocking block 15 is separated from the push rod 611. The fifth elastic member 613 pushes the push rod 611 to move back to its original position. The push rod 611 pushes the push rod 612 to move upward through the chamfer of the lifting groove 27, and the bottom end of the push rod 612 abuts against the top wall of the push rod 611. The third roller 26 at the top end of the push rod 612 abuts against the bottom of the basket grille 8 and locks the basket grille 8 again.
