Description

Technical Field

[0001] This invention relates to the field of water supply pumping station technology, and in particular to an integrated superimposed flow pumping station. Background Technology

[0002] Pressure booster systems, also known as pressureless water supply systems, eliminate the need for water storage tanks or rooftop water tanks. Using pressure booster systems can reduce initial equipment investment and fully utilize the water pressure of the municipal water supply network. It can also maintain the water pressure of the municipal water supply network during power outages and peak water supply periods.

[0003] A search revealed that the invention patent with application publication number CN115492189A discloses a box-type integrated superimposed pump station water supply equipment, including a base, a water tank, fixedly installed on the top of the base, a water pump unit, fixedly installed on the top of the base and located in front of the water tank, a placement box fixedly installed on the left side of the water tank, a filter box fixedly installed inside the placement box, and a water inlet pipe connected to the left side of the filter box.

[0004] However, after practical application by those skilled in the art, the above-mentioned equipment still has some drawbacks. The most obvious one is that when collecting dirt by suction using a telescopic airbag, a lot of water is absorbed along with the dirt. In order to reduce the difficulty of subsequent dirt treatment, a second filter screen is required to separate the dirt and water. However, the second filter screen needs to be cleaned manually periodically, which is still quite inconvenient in actual use.

[0005] Therefore, it is necessary to invent an integrated superimposed flow pump station to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide an integrated stacked cross-flow pump station. By first swapping the positions of two arc-shaped filter screens, the normal filtration of water is ensured. Subsequently, the dirt on the outside of the arc-shaped filter screens is removed by scraping. During the dirt removal and discharge process, there is no excessive simultaneous output of water, thereby effectively reducing the total amount of dirt and reducing the difficulty of dirt treatment. At the same time, no additional manual cleaning is required. This solves the problem mentioned in the background art where when using a telescopic airbag to collect dirt by suction, a lot of water is absorbed along with the dirt. In order to reduce the difficulty of subsequent dirt treatment, a second filter screen is required to separate dirt and water. However, the second filter screen requires periodic manual cleaning, which is still inconvenient in actual use.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an integrated stacked cross-flow pump station, comprising a water tank, a cross-flow pump unit connected to the front of the water tank, a water transfer mechanism connected to the left side of the water tank, a first power unit fixedly installed on the front of the water transfer mechanism, a second power unit installed outside the first power unit, and a reversing filter mechanism and a dirt removal mechanism installed inside the water transfer mechanism, with the dirt removal mechanism located above the reversing filter mechanism;

[0008] The first power unit drives the second power unit to move backward. When the second power unit moves backward, it first drives the two arc-shaped filter screens in the reversing filter mechanism to switch positions, and then triggers the dirt removal mechanism. The dirt removal mechanism removes dirt from the upper arc-shaped filter screen in the reversing filter mechanism, and the water transmission mechanism discharges the dirt.

[0009] Preferably, the water transfer mechanism includes a housing, a shielding door, a guide plate, an inlet pipe, and an outlet pipe;

[0010] The outer casing is fixedly installed on the left side of the water tank. A drain outlet is provided on the rear side of the outer casing. The shield door is located outside the drain outlet and is movably connected to the outer casing. The guide plate is located below the shield door and is fixedly connected to the outer casing. The inlet pipe is fixedly installed through the front of the outer casing, and the outlet pipe is fixedly installed through the back of the outer casing and communicates with the water tank.

[0011] Preferably, the first power unit includes a U-shaped frame, a reciprocating screw, a drive motor, an L-shaped push plate, a first spring, and a tubular component;

[0012] The U-shaped frame is fixedly mounted on the front of the outer casing.

The drive motor is fixedly mounted on the front of the U-shaped frame and is connected to the reciprocating screw in a transmission manner. The L-shaped push plate is sleeved on the outside of the reciprocating screw and is connected to it in a transmission manner. The first spring is fixedly connected between the L-shaped push plate and the tubular component. The tubular component is slidably sleeved on the outside of the reciprocating screw.

[0013] Preferably, the second power unit includes a mounting frame, a first threaded sleeve, a movable plate, and a second threaded sleeve;

[0014] The mounting frame is fixedly mounted on the rear end of the tubular component. The first threaded sleeve is nested inside the mounting frame via an overrunning clutch. The movable plate is fixedly mounted on the rear end of the L-shaped push plate and slidably mounted inside the U-shaped frame. The movable plate is slidably nested on the outer side of the tubular component via a groove and a slider. The second threaded sleeve is movably mounted on the top front of the movable plate via a bearing.

[0015] Preferably, the reversing filter mechanism includes a sealing block, a hollow cylinder, a first one-way screw, an arc-shaped filter screen, a sealing cover, and a transmission pipe;

[0016] Two sealing blocks are provided, symmetrical to each other and fixedly connected to the inner wall of the outer shell. The hollow cylinder is slidably fitted between the two sealing blocks and is nested inside the outer shell through a bearing. The rear end of the hollow cylinder is sleeved on the outside of the water outlet pipe through a rotary joint. The first one-way screw is fixedly installed on the front of the hollow cylinder and extends to the outside of the outer shell. The first one-way screw is driven inside the first threaded sleeve. Two arc-shaped filter screens, sealing covers, and transmission pipes are provided. The two sealing covers are nested on the top and bottom of the hollow cylinder, respectively. The two sealing covers are fixedly installed inside the hollow cylinder and are symmetrical to each other. A water storage chamber is formed between the sealing cover and the adjacent arc-shaped filter screen. The two transmission pipes are fixedly installed through the inner sides of the two sealing covers, and a one-way valve is provided on the transmission pipe.

[0017] Preferably, the decontamination mechanism includes a second one-way screw, a third one-way screw, a movable frame, a decontamination scraper, a second spring, a protrusion, and a guide rail;

[0018] The second one-way screw penetrates the front of the housing and extends into the housing. The second one-way screw is rotatably connected to the housing via a bearing. The third one-way screw is fixedly installed at the front end of the second one-way screw. The moving frame is driven and sleeved on the outside of the second one-way screw. The cleaning scraper is slidably installed on the inside of the moving frame in the vertical direction. The second spring is fixedly connected between the moving frame and the cleaning scraper. The protrusion is fixedly installed on the top of the cleaning scraper. The guide rail slides against the top of the protrusion and is fixedly installed on the top of the inner cavity of the housing.

[0019] This invention also discloses a method for removing contaminants from an integrated superimposed flow pump station, specifically including the following steps:

[0020] S1. Water enters the bottom of the inner cavity of the outer shell through the inlet pipe. Due to the obstruction of the two sealing blocks, the water is filtered by the lower arc-shaped filter screen and then enters the water storage chamber formed by the lower arc-shaped filter screen and the sealing cover. Then it enters the hollow cylinder through the lower transmission pipe and finally enters the water tank through the outlet pipe for storage.

[0021] S2. When the lower arc-shaped filter screen is being cleaned, the drive motor is started. After the drive motor starts, it drives the reciprocating screw to rotate. When the reciprocating screw rotates, it drives the L-shaped push plate to move backward. When the L-shaped push plate moves backward, it drives the tubular part to move backward through the first spring. It drives the second threaded sleeve to move backward through the moving plate. When the tubular part moves backward, it drives the first threaded sleeve to move backward through the mounting frame. When the first threaded sleeve moves backward, it drives the first one-way screw on its inner side to rotate. When the first one-way screw rotates, it drives the two sets of arc-shaped filter screens to switch positions through the hollow cylinder.

[0022] S3. The two arc-shaped filter screens have completed their swapping. At this time, the rear end of the first threaded sleeve is in contact with the front of the outer shell. Due to the obstruction of the outer shell, the first threaded sleeve cannot continue to move backward. Subsequently, as the L-shaped push plate continues to move backward, the first spring is compressed by the L-shaped push plate, and at the same time, the moving plate continues to drive the second threaded sleeve to move backward.

[0023] S4. The second threaded sleeve is sleeved on the outside of the third one-way screw because the moving plate is sleeved on the outside of the second threaded sleeve. As the second threaded sleeve continues to move backward, the third one-way screw drives the second one-way screw to rotate. When the second one-way screw rotates, it drives the moving frame to move backward. When the moving frame moves backward, it drives the protrusion to move backward through the cleaning scraper. When the protrusion moves backward, it is pressed downward by the inclined surface at the front end of the guide rail. The protrusion drives the cleaning scraper to move downward. When the cleaning scraper moves downward, it compresses the second spring.

[0024] S5. The bottom of the cleaning scraper is in contact with the outer surface of the arc-shaped filter screen to be cleaned. As the moving frame continues to move backward, the cleaning scraper scrapes off the dirt on the outer surface of the arc-shaped filter screen and pushes the dirt towards the drain outlet.

[0025] S6, the L-shaped push plate moves to the last end of the reciprocating thread on the outside of the reciprocating screw, and the moving frame moves to the rear end of the second unidirectional screw. At this time, the dirt falls through the drain port onto the top of the guide plate and is output under the push of the dirt removal scraper. Subsequently, as the reciprocating screw continues to rotate, the L-shaped push plate moves forward and resets.

[0026] S7. The compressed first spring is reset due to the movement of the L-shaped push plate. Subsequently, as the L-shaped push plate continues to move forward, the L-shaped push plate drives the tubular part to move forward synchronously through the first spring. The tubular part drives the first threaded sleeve to move forward synchronously through the mounting frame. At this time, due to the limitation of the overrunning clutch, the first one-way screw does not rotate.

[0027] S8, the L-shaped push plate arrives at the initial position, that is, the front end of the reciprocating thread on the outer side of the reciprocating screw, at which point the drive motor stops.

[0028] The technical effects and advantages of this invention are as follows:

[0029] This invention utilizes a first power unit to drive a second power unit to move backward. When the second power unit moves backward, it first causes the two arc-shaped filter screens in the reversing filter mechanism to switch positions, and then triggers the cleaning mechanism. After being triggered, the cleaning mechanism cleans the upper arc-shaped filter screen in the reversing filter mechanism until the dirt is discharged through the water transmission mechanism. Compared with existing similar devices, this invention first switches the two arc-shaped filter screens to ensure the normal operation of water filtration, and then removes the dirt on the outside of the arc-shaped filter screen by scraping. During the dirt removal and discharge process, there is no excessive simultaneous output of water, which effectively reduces the total amount of dirt, reduces the difficulty of dirt treatment, and eliminates the need for additional manual cleaning.

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0038] Example 1

[0039] This invention provides, for example Figures 1-6An integrated stacked cross-flow pump station is shown, including a water tank 1. A cross-flow pump unit 2 is connected to the front of the water tank 1. A water transfer mechanism 3 is connected to the left side of the water tank 1. A first power unit 4 is fixedly installed on the front of the water transfer mechanism 3. A second power unit 5 is installed outside the first power unit 4. A reversing filter mechanism 6 and a dirt removal mechanism 7 are installed inside the water transfer mechanism 3. The dirt removal mechanism 7 is located above the reversing filter mechanism 6.

[0040] The first power unit 4 drives the second power unit 5 to move backward. When the second power unit 5 moves backward, it first drives the two arc-shaped filter screens 64 in the reversing filter mechanism 6 to change position, and then triggers the dirt removal mechanism 7. The dirt removal mechanism 7 removes dirt from the arc-shaped filter screen 64 located at the top in the reversing filter mechanism 6, and the water transmission mechanism 3 discharges the dirt.

[0041] like Figure 3 As shown, the water transfer mechanism 3 includes a housing 31, a shielding door 32, a guide plate 33, an inlet pipe 34, and an outlet pipe 35. The housing 31 is fixedly installed on the left side of the water tank 1, and a drain outlet is provided on the rear side of the housing 31. The shielding door 32 is located outside the drain outlet and is movably connected to the housing 31. The guide plate 33 is located below the shielding door 32 and is fixedly connected to the housing 31. The inlet pipe 34 is fixedly installed through the front of the housing 31, and the outlet pipe 35 is fixedly installed through the back of the housing 31 and communicates with the water tank 1.

[0042] like Figure 4 As shown, the first power unit 4 includes a U-shaped frame 41, a reciprocating screw 42, a drive motor 43, an L-shaped push plate 44, a first spring 45, and a tubular component 46. The U-shaped frame 41 is fixedly mounted on the front of the housing 31. The reciprocating screw 42 passes through the U-shaped frame 41 and is rotatably connected to the U-shaped frame 41 via a bearing. The drive motor 43 is fixedly mounted on the front of the U-shaped frame 41 and is drive-connected to the reciprocating screw 42. The L-shaped push plate 44 is sleeved on the outside of the reciprocating screw 42 and is drive-connected to it. The first spring 45 is fixedly connected between the L-shaped push plate 44 and the tubular component 46. The tubular component 46 is slidably sleeved on the outside of the reciprocating screw 42.

[0043] like Figure 4As shown, the second power unit 5 includes a mounting frame 51, a first threaded sleeve 52, a movable plate 53, and a second threaded sleeve 54. The mounting frame 51 is fixedly disposed at the rear end of the tubular component 46. The first threaded sleeve 52 is nested inside the mounting frame 51 via an overrunning clutch. The movable plate 53 is fixedly disposed at the rear end of the L-shaped push plate 44 and slidably disposed inside the U-shaped frame 41. The movable plate 53 is slidably nested with a slider via a groove on the outside of the tubular component 46. The second threaded sleeve 54 is movably disposed through the top front of the movable plate 53 via a bearing.

[0044] By setting up the first power unit 4 and the second power unit 5, the reciprocating screw 42 is driven to rotate after the drive motor 43 starts. When the reciprocating screw 42 rotates, it drives the L-shaped push plate 44 to move backward. When the L-shaped push plate 44 moves backward, it drives the tubular part 46 to move backward through the first spring 45. The second threaded sleeve 54 is driven to move backward through the moving plate 53. When the tubular part 46 moves backward, it drives the first threaded sleeve 52 to move backward through the mounting frame 51. When the first threaded sleeve 52 can no longer move backward, the first spring 45 is compressed by the L-shaped push plate 44 as the L-shaped push plate 44 continues to move backward. At the same time, the moving plate 53 continues to drive the second threaded sleeve 54 to move backward.

[0045] like Figure 5 As shown, the reversing filter mechanism 6 includes a sealing block 61, a hollow cylinder 62, a first one-way screw 63, an arc-shaped filter screen 64, a sealing cover 65, and a transmission pipe 66. Two sealing blocks 61 are provided, symmetrically arranged and fixedly connected to the inner wall of the outer casing 31. The hollow cylinder 62 is slidably fitted between the two sealing blocks 61 and is rotatably nested inside the outer casing 31 via bearings. The rear end of the hollow cylinder 62 is sleeved onto the outside of the outlet pipe 35 via a rotary joint. The first one-way screw 63 is fixedly disposed on the front side of the hollow cylinder 62. Extending to the outside of the outer shell 31, the first one-way screw 63 is driven and disposed inside the first threaded sleeve 52. Two of the arc-shaped filter screen 64, sealing cover 65 and transmission pipe 66 are provided. The two sealing covers 65 are respectively nested in the top and bottom of the hollow cylinder 62. The two sealing covers 65 are fixedly disposed inside the hollow cylinder 62 and are symmetrically arranged with each other. A water storage chamber is formed between the sealing cover 65 and the adjacent arc-shaped filter screen 64. The two transmission pipes 66 are respectively fixedly disposed through the inside of the two sealing covers 65. A one-way valve is provided on the transmission pipe 66.

[0046] By setting up the water transmission mechanism 3 and the reversing filter mechanism 6, when water enters the bottom of the inner cavity of the outer shell 31 through the inlet pipe 34, due to the obstruction of the two sealing blocks 61, the water is filtered by the lower arc-shaped filter screen 64 and enters the water storage chamber formed by the lower arc-shaped filter screen 64 and the sealing cover 65. Then, it enters the hollow cylinder 62 through the lower transmission pipe 66, and finally enters the water tank 1 through the outlet pipe 35 for storage. When the first threaded sleeve 52 moves backward, the first threaded sleeve 52 drives the first one-way screw 63 inside it to rotate. When the first one-way screw 63 rotates, it drives the two sets of arc-shaped filter screens 64 to switch positions through the hollow cylinder 62.

[0047] like Figure 6 As shown, the cleaning mechanism 7 includes a second one-way screw 71, a third one-way screw 72, a movable frame 73, a cleaning scraper 74, a second spring 75, a protrusion 76, and a guide rail 77. The second one-way screw 71 penetrates the front of the housing 31 and extends into the interior of the housing 31. The second one-way screw 71 is rotatably connected to the housing 31 via a bearing. The third one-way screw 72 is fixedly disposed at the front end of the second one-way screw 71. The movable frame 73 is drivenly sleeved on the outside of the second one-way screw 71. The cleaning scraper 74 is slidably disposed on the inside of the movable frame 73 in a vertical direction. The second spring 75 is fixedly connected between the movable frame 73 and the cleaning scraper 74. The protrusion 76 is fixedly disposed at the top end of the cleaning scraper 74. The guide rail 77 is slidably attached to the top end of the protrusion 76 and fixedly disposed at the top of the inner cavity of the housing 31.

[0048] By setting the above structure, after the second threaded sleeve 54 is sleeved on the outside of the third one-way screw 72, as the second threaded sleeve 54 continues to move backward, the third one-way screw 72 drives the second one-way screw 71 to rotate. When the second one-way screw 71 rotates, it drives the moving frame 73 to move backward. When the moving frame 73 moves backward, it drives the protrusion 76 to move backward through the cleaning scraper 74. When the protrusion 76 moves backward, it is pressed downward by the inclined surface at the front end of the guide rail 77. The protrusion 76 drives the cleaning scraper 74 to move downward, thus removing dirt. When the scraper 74 moves downward, it compresses the second spring 75 until the bottom of the scraper 74 is in contact with the outer surface of the arc-shaped filter screen 64 to be cleaned. Subsequently, as the moving frame 73 continues to move backward, the scraper 74 scrapes off the dirt on the outer surface of the arc-shaped filter screen 64 and pushes the dirt towards the drain port. When the moving frame 73 moves to the outer rear end of the second one-way screw 71, the dirt falls through the drain port onto the top of the guide plate 33 and is output under the push of the scraper 74.

[0049] Example 2

[0050] This invention also discloses a method for removing contaminants from an integrated superimposed flow pump station, specifically including the following steps:

[0051] S1. Water enters the bottom of the inner cavity of the outer shell 31 through the water inlet pipe 34. Due to the obstruction of the two sealing blocks 61, the water is filtered by the lower arc-shaped filter screen 64 and enters the water storage chamber formed by the lower arc-shaped filter screen 64 and the sealing cover 65. Then, it enters the hollow cylinder 62 through the lower transmission pipe 66 and finally enters the water tank 1 through the water outlet pipe 35 for storage.

[0052] S2. When the lower arc-shaped filter screen 64 is cleaning, the drive motor 43 is started. After the drive motor 43 starts, it drives the reciprocating screw 42 to rotate. When the reciprocating screw 42 rotates, it drives the L-shaped push plate 44 to move backward. When the L-shaped push plate 44 moves backward, it drives the tubular part 46 to move backward through the first spring 45. It drives the second threaded sleeve 54 to move backward through the moving plate 53. When the tubular part 46 moves backward, it drives the first threaded sleeve 52 to move backward through the mounting frame 51. When the first threaded sleeve 52 moves backward, it drives the first one-way screw 63 inside it to rotate. When the first one-way screw 63 rotates, it drives the two sets of arc-shaped filter screens 64 to switch positions through the hollow cylinder 62.

[0053] S3. The two arc-shaped filter screens 64 have completed the swap. At this time, the rear end of the first threaded sleeve 52 is in contact with the front of the outer shell 31. Due to the obstruction of the outer shell 31, the first threaded sleeve 52 cannot continue to move backward. Subsequently, as the L-shaped push plate 44 continues to move backward, the first spring 45 is compressed by the L-shaped push plate 44. At the same time, the moving plate 53 continues to drive the second threaded sleeve 54 to move backward.

[0054] S4. The second threaded sleeve 54 is sleeved on the outside of the third one-way screw 72 because the moving plate 53 is sleeved on it. As the second threaded sleeve 54 continues to move backward, the third one-way screw 72 drives the second one-way screw 71 to rotate. When the second one-way screw 71 rotates, it drives the moving frame 73 to move backward. When the moving frame 73 moves backward, it drives the protrusion 76 to move backward through the cleaning scraper 74. When the protrusion 76 moves backward, it is pressed downward by the inclined surface at the front end of the guide rail 77. The protrusion 76 drives the cleaning scraper 74 to move downward. When the cleaning scraper 74 moves downward, it compresses the second spring 75.

[0055] S5. The bottom end of the cleaning scraper 74 is attached to the outer surface of the arc-shaped filter screen 64 to be cleaned. As the moving frame 73 continues to move backward, the cleaning scraper 74 scrapes off the dirt on the outer surface of the arc-shaped filter screen 64 and pushes the dirt towards the drain outlet.

[0056] S6, the L-shaped push plate 44 moves to the last end of the reciprocating thread on the outside of the reciprocating screw 42, and the moving frame 73 moves to the rear end of the second one-way screw 71. At this time, the dirt falls through the drain port onto the top of the guide plate 33 and is output under the push of the dirt removal scraper 74. Subsequently, as the reciprocating screw 42 continues to rotate, the L-shaped push plate 44 moves forward and resets.

[0057] S7. The compressed first spring 45 is reset due to the movement of the L-shaped push plate 44. Subsequently, as the L-shaped push plate 44 continues to move forward, the L-shaped push plate 44 drives the tubular part 46 to move forward synchronously through the first spring 45. The tubular part 46 then drives the first threaded sleeve 52 to move forward synchronously through the mounting frame 51. At this time, due to the limitation of the overrunning clutch, the first one-way screw 63 does not rotate.

[0058] S8, the L-shaped push plate 44 arrives at the initial station, that is, the outermost end of the reciprocating thread on the outside of the reciprocating screw 42, at which point the drive motor 43 is stopped.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
