Description

Technical Field

[0001] This invention belongs to the field of pumping station technology, and in particular relates to a high-efficiency and energy-saving drainage pumping station for water conservancy projects. Background Technology

[0002] Flood control and drainage planning is an important part of urban infrastructure engineering planning and design, and a guarantee for the sustainable development of cities. Flooding is caused by surface runoff formed by rainfall in urban areas, which in turn leads to water accumulation and inundation losses due to the inability to drain water in time.

[0003] Currently, urban river drainage pumping stations generally operate in two ways: gravity drainage and forced drainage. When the water level of the inland river is higher than that of the outer river, gravity drainage can be carried out. During gravity drainage, the valves of the gate chamber need to be opened to allow the water in the river to flow on its own. When the water level of the inland river is lower than that of the outer river, forced drainage is required. Forced drainage requires closing the working gate and using the submersible pumps on the gate to forcefully drain the water.

[0004] Regardless of the drainage method, to ensure the safe and smooth operation of the pumping station, most rivers will have a debris removal machine installed in the river channel. This machine will lift and separate large debris from the river channel, allowing the water to flow through. However, debris removal machines can usually only remove larger debris such as tree branches from the river channel. They are less effective at handling silt and sand particles. Smaller silt and sand particles are fine when discharged, but larger particles will erode the pump blades during pumping, causing significant damage to the pump blades. Summary of the Invention

At the same time, the liftable sealing guide plate can be raised and lowered to clear the first and second filter holes, reducing the need for manual clearing operations. Attached Figure Description

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0033] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0034] This invention provides a high-efficiency and energy-saving drainage pumping station for water conservancy projects, such as... Figure 1-13 As shown, the high-efficiency and energy-saving drainage pumping station for water conservancy projects includes: a pumping platform 2 built on a river channel 1, a gate 3 and a cleaning machine 7 located in the river channel 1; a gate pump 4 is installed on the gate 3, and a rear maintenance gate 5 and a front maintenance gate 6 are located on both sides of the gate 3 in the river channel 1; the cleaning machine 7 is located on the water inlet side of the front maintenance gate 6 away from the gate 3; and an adjustable filter plate is installed between the front maintenance gate 6 and the cleaning machine 7 for filtering silt particles; a conveyor belt 8 is installed on the river channel 1 to cooperate with the cleaning machine 7.

[0035] It should be noted that urban river drainage pumping stations generally operate in two ways: gravity drainage and forced drainage. When the water level of the inland river is higher than that of the outer river, gravity drainage can be carried out. During gravity drainage, the valves of the gate chamber need to be opened to allow the water in the river to flow on its own. When the water level of the inland river is lower than that of the outer river, forced drainage is required. Forced drainage requires closing the working gate and using the submersible pumps on the gate to force the drainage.

[0036] Regardless of the drainage method, to ensure the safe and smooth operation of the pumping station, most rivers will have cleaning machines installed in the riverbed to remove large impurities by lifting them out, allowing the river water to pass through.

[0037] Currently, people usually use cleaning machines to remove larger debris such as tree branches from river channels. The advantage of cleaning machines is that they can continuously discharge debris from the river channel and operate without interruption. However, cleaning machines are not very effective at handling silt particles. Smaller silt particles are fine when discharged, but larger silt particles will wash away the pump blades when the pump is running to drain water, causing greater damage to the pump blades and increasing the operating cost of the pumping station.

[0038] In this embodiment, the pumping station adopts conventional operation mode. When the water level of the inland river is higher than that of the outer river, gravity drainage can be carried out. During gravity drainage, gate 3 needs to be opened to allow the water in the river channel 1 to flow by itself. When the water level of the inland river is lower than that of the outer river, forced drainage is required. Forced drainage requires closing the working gate 3 and using the gate pump 4 on the gate 3 to force drainage. When the pumping station is running, the cleaning machine 7 discharges large garbage from the river channel 1 in real time at the front side and discharges it to the outer cleaning site through the conveyor belt 8. During forced drainage, the incoming river water is filtered through the sand filter plate to filter out larger sand particles and impurities in the river water, reducing the damage of impurities to the pump blades of the gate pump 4 and reducing maintenance costs.

[0039] In a further preferred embodiment of the present invention, the sand filter plate includes: two outer filter plates 9 disposed in the river channel 1 and having a plurality of first filter holes 11; and an inner filter plate 10 slidably disposed between the two outer filter plates 9 and having a plurality of second filter holes 12, wherein the inner filter plate 10 is used to cooperate with the two outer filter plates 9 to adjust the positions of the first filter holes 11 and the second filter holes 12 to filter silt particles.

[0040] In this embodiment, when the sand filter plate is running, the inner filter plate 10, which is slidable inside the two outer filter plates 9, can be adjusted so that the height position of the first filter hole 11 and the second filter hole 12 is staggered, thereby adjusting the size of the sand particles and impurities that pass through. It can be adjusted at different stages as needed, making it flexible and versatile.

[0041] In a further preferred embodiment of the present invention, the top of the two outer filter plates 9 are fixedly installed with the same connecting plate frame 13. The connecting plate frame 13 has multiple assembly ports 14. Each of the multiple assembly ports 14 is fixedly installed with a hydraulic cylinder 15. The output rods of the multiple hydraulic cylinders 15 are fixedly connected to the top of the inner filter plate 10.

[0042] In this embodiment, the connecting plate frame 13 connects two outer filter plates 9, which can be linked together when suspended. When adjusting the position of the inner filter plate 10, the hydraulic cylinder 15 is activated, causing the output rod of the hydraulic cylinder 15 to extend and retract, thereby driving the inner filter plate 10 to slide between the two outer filter plates 9, realizing the adjustment of the misalignment of the first filter hole 11 and the second filter hole 12, and realizing the adjustment of filtration. The way in which the two outer filter plates 9 clamp one inner filter plate 10 can ensure the stability of the inner filter plate 10 during use, and prevent it from being separated by the impact of river water, ensuring the tight fit between the outer filter plate 9 and the inner filter plate 10.

[0043] In a further preferred embodiment of the present invention, a sealing guide plate 16 is slidably installed in each of the plurality of second filter holes 12. An assembly groove 19 is provided on the top inner wall of the plurality of second filter holes 12 in the uppermost row. A receiving opening 17 is provided on the bottom inner wall of the plurality of other second filter holes 12. The receiving opening 17 is adapted to the sealing guide plate 16. The same connecting rod 18 is fixedly installed on the plurality of sealing guide plates 16 in the same column. The connecting rod 18 slides through the plurality of second filter holes 12 and the receiving opening 17 in the same column.

[0044] In this embodiment, during use, since the second filter hole 12 and the first filter hole 11 have a high position difference most of the time, in order to avoid a large amount of silt accumulating in the second filter hole 12, the sealing guide plate 16 can balance the height of the second filter hole 12 and the first filter hole 11, so that the silt can pass through smoothly. The sealing guide plates 16 in the same row are connected by the same connecting rod 18, and are adjusted synchronously, which is simple and convenient to operate. The storage port 17 can store the sealing guide plate 16 when the second filter hole 12 and the first filter hole 11 are completely aligned, reducing the impact on the passing river water.

[0045] In a further preferred embodiment of the present invention, a threaded rod 20 is provided in the assembly groove 19, the bottom end of the threaded rod 20 is fixedly connected to the corresponding sealing guide plate 16, a threaded sleeve 21 is threadedly fitted on the threaded rod 20, the threaded sleeve 21 is rotatably connected to the assembly groove 19 by a bearing, an assembly port 22 is provided on the inner filter plate 10, a drive motor 23 is fixedly installed in the assembly port 22, and the output shaft of the drive motor 23 extends into the assembly groove 19 and is fixedly connected to the top end of the threaded sleeve 21.

[0046] In this embodiment, when adjusting the position of the sealing guide plate 16, the drive motor 23 is started. The output shaft of the drive motor 23 drives the threaded sleeve 21 to rotate. When the threaded sleeve 21 rotates, it drives the threaded rod 20 to slide up or down, thereby adjusting the height of the sealing guide plate 16 and achieving quick and labor-saving adjustment. In this device, multiple drive motors 23 can be controlled independently. They can be adjusted differently according to the amount of sediment at the position near the riverbank and in the middle of the river channel 1, or they can be controlled synchronously.

[0047] In a further preferred embodiment of the present invention, air passages 24 are provided on both of the outer filter plates 9, the air passages 24 extend to the bottom of the outer filter plates 9, and air holes 25 communicating with the air passages 24 are provided at the bottom of both outer filter plates 9, and the plurality of air holes 25 are inclined toward the drainage side.

[0048] In this embodiment, when the pump station is regulated, the sand filter plate consisting of the outer filter plate 9 and the inner filter plate 10 needs to be extracted and then submerged again. Since the bottom of the river channel 1 usually contains silt, in order to increase the sealing of the sand filter plate, an external air source can be connected through the air passage 24 to pump in high-pressure air, which is then discharged through the air hole 25 set at an angle towards the drainage side. This allows the silt at the bottom of the river channel 1 to be flushed towards the drainage side and flow downstream. At this time, the sand filter plate can descend and sink to the bottom of the river channel 1 relatively smoothly, ensuring the sealing of the placement. Similarly, the gate 3, the rear maintenance gate 5, and the front maintenance gate 6 in this pump station can all adopt the same method.

[0049] In a further preferred embodiment of the present invention, an air pipe 26 connected to the air passage 24 is fixedly installed on the external filter plate 9. The air pipe 26 can slide through the pump station 2. An aeration fan 27 is provided on the pump station 2. The exhaust end of the aeration fan 27 is fixedly connected to the air inlet end of the air pipe 26.

[0050] In this embodiment, during air supply, the aeration blower 27 pumps high-pressure air into the air passage 24 through the air pipe 26. The air pipe 26 is telescopic or slidable, adapting to the lifting and lowering of the filter sand plate.

[0051] In a further preferred embodiment of the present invention, the top of the pump station platform 2 is provided with a plurality of secondary housings 28 and a main housing 29. The plurality of secondary housings 28 are respectively distributed corresponding to the filter sand plate, the rear maintenance gate 5 and the front maintenance gate 6. The main housing 29 is distributed corresponding to the gate 3. A winding shaft 30 is rotatably installed inside the plurality of secondary housings 28 and the main housing 29. A cable 31 that slides through the pump station platform 2 is wound on the plurality of winding shafts 30. The plurality of cables 31 are respectively hoisted and connected to the gate 3, the rear maintenance gate 5, the front maintenance gate 6 and the connecting plate frame 13. A winding motor 32 is fixedly installed on one side of the plurality of secondary housings 28 and the main housing 29. The output shafts of the plurality of winding motors 32 are respectively fixedly connected to one end of the plurality of winding shafts 30.

[0052] In this embodiment, when lifting gate 3, rear maintenance gate 5, front maintenance gate 6 and filter sand plate are in operation, the corresponding winding motor 32 can be started. The output shaft of the winding motor 32 drives the winding shaft 30 to rotate, thereby realizing the winding and release of the cable 31, and thus realizing the lifting and lowering of lifting gate 3, rear maintenance gate 5, front maintenance gate 6 and filter sand plate.

[0053] In a further preferred embodiment of the present invention, a positioning gear 33 is disposed inside the main housing 29, the positioning gear 33 is fixedly sleeved on the corresponding take-up shaft 30, a guide frame 34 is fixedly installed inside the main housing 29, a slide plate 35 is slidably sleeved on the guide frame 34, a positioning tooth 36 that meshes with the positioning gear 33 is fixedly installed on the slide plate 35, and a second hydraulic cylinder 37 is fixedly installed on the top of the main housing 29, the output rod of the second hydraulic cylinder 37 extends into the main housing 29 and is fixedly connected to the slide plate 35.

[0054] In this embodiment, since the gate 3 is under high pressure during use, in order to increase the load-bearing capacity of the winding shaft 30 during suspension and reduce the output shaft pressure of the winding motor 32, the slide plate 35 driven by the hydraulic cylinder 37 can be raised and lowered so that the positioning teeth 36 mesh with the positioning gear 33, thereby preventing the winding shaft 30 from rotating. The guide frame 34 can increase the correction force of the slide plate 35.

[0055] In a further preferred embodiment of the present invention, the plurality of first filter holes 11 and second filter holes 12 are all rectangularly arranged, and the plurality of first filter holes 11 and second filter holes 12 are correspondingly arranged.

[0056] In this embodiment, the rectangular first filter hole 11 and second filter hole 12 can be used well with the sealing guide plate 16 to ensure that the first filter hole 11 and the second filter hole 12 are on the same horizontal line after adjustment. This allows water to flow through the first filter hole 11, the second filter hole 12 and the sealing guide plate 16, avoiding the problem of sediment accumulation caused by misalignment of the first filter hole 11 and the second filter hole 12, and reducing the probability of blockage. At the same time, the liftable sealing guide plate 16 can be raised and lowered to clear the first filter hole 11 and the second filter hole 12, reducing the need for manual clearing operations. In specific implementation, it is only necessary to frequently raise and lower the sealing guide plate 16 to change the flow hole.

[0057] In summary, the variable sand filter plates used in this pumping station can filter silt particles in the river, reduce damage to the pump blades, and lower maintenance costs.

[0058] Compared with related technologies, this device uses variable sand filter plates to filter silt particles in the river, which not only reduces the damage of silt particles to the pump blades and lowers maintenance costs, but also allows the first filter hole 11 and the second filter hole 12 to be aligned at the same horizontal line after adjustment. This allows water to flow through the first filter hole 11, the second filter hole 12 and the sealing guide plate 16, avoiding the problem of silt accumulation caused by misalignment of the first filter hole 11 and the second filter hole 12, and reducing the probability of blockage. At the same time, the liftable sealing guide plate 16 can be raised and lowered to clear the first filter hole 11 and the second filter hole 12, reducing the need for manual clearing operations.
