Description

Technical Field

[0001] This invention belongs to the field of water conservancy engineering technology, specifically relating to an integrated filtration and interception pumping station. Background Technology

[0002] A pumping station is a device and engineering project that provides hydraulic and pneumatic power with a certain pressure and flow rate. It encompasses the water intake, water outlet, pump house, and other structures of an irrigation and drainage pumping station. Applying pumping stations to river management (i.e., using river water for irrigation, which greatly reduces the number of wells needed for farmland, lowers initial investment costs, and reduces the use of groundwater) not only prevents waterlogging but also provides water supply, making it significant for both farmland irrigation and river management.

[0003] However, since branches, weeds, and floating objects are everywhere in the river channels and canals, direct use of these materials for irrigation will affect the ecological environment of the paddy fields and will also block the inlet of the pumping station. In addition, the flow of water discharged into the paddy fields needs to be reasonably controlled, otherwise, excessive irrigation will easily cause flooding and affect the growth of crops. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of existing rivers and canals, such as the large amount of floating debris and the excessive irrigation volume, which makes them unsuitable for farmland irrigation and river management, and to provide a filter-intercepting integrated pump station.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is: an integrated filtration and interception pumping station, comprising:

[0006] The system comprises: a base plate, a pier fixed to the top of the base plate, a debris-blocking channel formed inside the pier, a debris-blocking grid inserted in the debris-blocking channel, multiple sets of maintenance piles fixed to the top of the base plate, a maintenance gate slot formed by the maintenance piles, a gate assembly that can be raised and lowered in the maintenance gate slot, a cut-off wall fixed to the top of the base plate, an outer river section set outside the debris-blocking grid, a filter section set between the debris-blocking grid and the gate assembly, a pumping section set between the cut-off wall and the gate assembly, a pumping section set outside the cut-off wall, and a pumping assembly connecting the pumping section and the pumping section.

[0007] The water in the outer river section enters the filtration section through the trash rack.

[0008] The pumping assembly is used to pump water from the inlet section into the outlet section.

[0009] Ideally, it also includes a pad layer integrally disposed at the bottom of the base plate, a pump hole opened on the cut-off wall, a top plate fixed to the top of the pier, and a maintenance platform fixed to the side of the cut-off wall away from the pumping section.

[0010] Optimally, the trash rack includes multiple sets of grid plates spaced apart, a grid groove opened on one side of the grid plate, a top beam and a bottom beam fixed to the top and bottom of the grid plate, a beam groove opened on the inner side of the top beam and the bottom beam, and a side beam fixed to the outer side of the top beam and the bottom beam, wherein the grid groove is engaged with the side of the top beam and the bottom beam.

[0011] Optimally, the maintenance pile includes a guide plate and a clamping plate fixed to the top of the base plate, a tie rod fixed to the inside of the guide plate and the clamping plate, and a sealing plate fixed to the inside of the guide plate and the clamping plate and used to abut the tie rod. The guide plate and the clamping plate are perpendicular to each other, and the maintenance door slot is arranged between two adjacent sets of clamping plates.

[0012] Optimally, the tie rod includes a first tie rod portion and a second tie rod portion integrally connected to one side of the first tie rod portion;

[0013] The sealing plate includes two sets of diagonal bracing parts arranged opposite each other, a pressing part connected to both ends of one set of diagonal bracing parts, a first locking edge connected to the pressing part, a second locking edge connected to the first locking edge, and a connecting part connecting the second locking edge and the other set of diagonal bracing parts. The pressing part abuts against the inner side of the guide plate and the locking plate. One side of the first tie rod abuts against the first locking edge, and the other side of the first tie rod abuts against the second locking edge.

[0014] Optimally, the pumping assembly includes an axial flow pump with one end fixed in the pumping section and the other end penetrating through the pump hole, an axial flow motor fixed on the top plate and connected to the axial flow pump, a support plate fixed between the piers, a sleeve sleeved on the axial flow pump and fixed to the support plate, a transition section integrally connected to one end of the axial flow pump and with a gradually decreasing diameter, a suction section connected to the end of the transition section, and a flap gate disposed at the other end of the axial flow pump.

[0015] Optimally, the gate assembly includes a gate body that is vertically and elliptically disposed in the maintenance gate slot, a baffle plate integrally connected to one side of the gate body, a stop plate integrally connected to the other side of the gate body, a main water-stop assembly fixed to the bottom of the gate body, a side water-stop assembly fixed to one side of the baffle plate, and lifting heads fixed to both sides of the gate body.

[0016] After the gate assembly descends into the maintenance gate slot, the main water-stop assembly is used to seal the bottom of the maintenance gate slot, and the side water-stop assembly is used to seal the side of the maintenance gate slot.

[0017] Optimally, the main water-stopping assembly includes an extension plate, bolts, nuts, a main washer plate, a main extrusion strip, and a support plate. The extension plate is fixed to one side of the gate body, the main extrusion strip abuts against the bottom of the extension plate, the main washer plate abuts against the side of the main extrusion strip away from the extension plate, the bolt passes through the main washer plate, the main extrusion strip, and the extension plate in sequence, the nut is screwed onto the end of the bolt, and the support plate is fixed between the extension plate and the water-stopping plate.

[0018] After the gate assembly descends into the maintenance gate slot, the main extrusion bar deforms and presses against the bottom of the maintenance gate slot.

[0019] Optimally, the side water-stop assembly includes a side pressure plate, a side pad, a screw, and a side extrusion strip. The side pressure plate is fixed to the water baffle plate, the side extrusion strip abuts against the side of the side pressure plate away from the water baffle plate, the side pad abuts against the side of the side extrusion strip away from the side pressure plate, and the screw passes through the side pad, the side extrusion strip, and the side pressure plate in sequence to fix it to the water baffle plate.

[0020] When the gate assembly descends into the maintenance gate slot, the side compression bar deforms and presses against the inner wall of the card plate.

[0021] Ideally, the lifting head includes a fixing plate fixed to both sides of the gate body, a lifting plate integrally connected to the outside of the fixing plate, and a lifting groove opened on the side of the lifting plate near the fixing plate.

[0022] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art:

[0023] This invention relates to an integrated filtration and interception pumping station. By setting up a debris-blocking channel and a debris-blocking grid between the side piers and the inner piers, the water flow in the outer river section is filtered, thereby intercepting suspended solids such as branches and weeds in the water flow. By setting up a lifting gate assembly in the maintenance gate slot, the opening and closing of the river channel and the channel can be realized, thereby achieving reasonable control of the irrigation volume. Finally, the pumping assembly pumps the water from the pumping section to the pumping section to complete the irrigation of farmland and the regulation of the river.

[0024] Furthermore, fixing baffles that are offset from the grid plates between the top beam and the bottom beam can effectively improve the filtration effect;

[0025] Furthermore, an inwardly inclined guide section is provided on the "I"-shaped side beam to reduce the impact of water flow on the trash rack;

[0026] Furthermore, the flap design prevents external impurities from entering the axial flow pump and thus clogging it. Attached Figure Description

[0074] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0075] like Figure 1 , 2 The diagram shows a cross-sectional view and a left view of the integrated filtration and interception pumping station of this invention. It is typically used in river regulation to filter water from the outer river side for use in water diversion, dredging, irrigation, and other projects, preventing river erosion and siltation, and better meeting the requirements of flood control and water conservancy. It includes a base plate 1, a cushion layer 2, side piers 3, inner piers 4, a maintenance platform 5, a trash rack 6, a trash rack 7, maintenance piles 8, a maintenance gate slot 9, a gate assembly 10, a cutoff wall 11, a pump hole 12, a top plate 13, a buffer block 14, an axial flow motor 15, an axial flow pump 16, a flap gate 17, a support plate 18, a sleeve 19, a transition section 20, a suction section 21, an outer river section 22, a filtration section 23, a pump inlet section 24, and a pump outlet section 25.

[0076] The base slab 1 is made of C30 reinforced concrete, which has a compressive strength of 30 MPa and a thickness of 600 mm. (Reinforced concrete refers to a composite material that improves the mechanical properties of concrete by incorporating steel mesh, steel plates, or fibers.) A matching layer 2 is placed at the bottom of the base slab 1. The layer 2 is made of 100 mm thick C30 plain concrete, also with a compressive strength of 30 MPa, and serves to further support the base slab 1.

[0077] like Figure 2 As shown, the side pier 3 and inner pier 4 are integrally fixed to the top of the base plate 1. By setting the side pier 3 and inner pier 4, the channel can be divided into multiple sets of water diversion channels. A debris barrier 6 is opened inside the side pier 3 and inner pier 4. A debris barrier 7 is inserted into the debris barrier 6. Under the action of the debris barrier 7, the water source on the outer river side is intercepted, thereby filtering out floating branches, weeds, etc. Multiple sets of maintenance piles 8 are fixed to the base plate 1 to form maintenance gate slots 9. Gate assemblies 10 are vertically and flexibly installed in the maintenance gate slots 9. By opening and closing the gate assembly 10, the flow of water or the interception of water can be achieved. Figure 1As shown, the outer side of the trash rack 7 is the outer river section 22; the area between the trash rack 7 and the gate assembly 10 is the filter section 23; the area between the gate assembly 10 and the cutoff wall 11 is the pump inlet section 24; and the outer side of the cutoff wall 11 is the pump outlet section 25. The pump outlet assembly is located within the pump inlet section 24 and is used to pump water from the pump inlet section 24 to the pump outlet section 25 for subsequent irrigation. The maintenance platform 5 is fixed to the side of the cutoff wall 11 away from the pump inlet section 24 for operators to periodically inspect the flap gate 17.

[0078] like Figure 3 The diagram shows a debris barrier 7, used to intercept floating branches, weeds, and other debris on the water flow within the outer river section 22. The debris barrier 7 includes a top beam 701, a bottom beam 702, a beam channel 703, barrier panels 704, a channel 705, a reinforcing plate 706, a reserved channel 707, side beams 708, and a flow guide 709. There are multiple sets of barrier panels 704, such as... Figure 5 As shown, the cross-section of the grid 704 is rectangular, and grid grooves 705 are formed on the top and bottom of one side of the grid 704. Figure 4 As shown, a top beam 701 and a bottom beam 702 are fixed to the top and bottom of the grid plate 704, and beam grooves 703 are formed on the inner sides of the top beam 701 and the bottom beam 702 (the cross-section of the top beam 701 and the bottom beam 702 is in the shape of "]"). In actual welding, as... Figure 4 As shown, the grid groove 705 of the grid plate 704 is engaged on one side of the "]"-shaped top beam 701 and bottom beam 702. By setting the grid groove 705 and beam groove 703, the contact area between the grid plate 704 and the top beam 701 and bottom beam 702 can be increased, thereby increasing the welding area during welding, improving the firmness after welding, and preventing the grid plate 704 from deforming under the pressure of long-term water flow, thus affecting the filtration effect.

[0079] like Figure 4 As shown, the top beam 701, shaped like an "]", has a pre-reserved groove 707 on the side away from the grid plate 704. The groove 707 is used to fix the grid plate between the top beam 701 and the bottom beam 702. The grid plate and the grid plate 704 are staggered in the direction of water flow to improve the filtration effect. There are two sets of side beams 708, which are fixed to the outside of the top beam 701 and the bottom beam 702 by welding. Figure 6 As shown, the side beam 708 is in the shape of an "I" and an inwardly inclined guide section 709 is provided on the "I" shaped side beam 708. The water flow in the outer river section 22 flows to the filter section 23 through the filter screen 7. Under the action of the screen plate 704, it can effectively intercept branches, weeds and other debris in the water flow. At this time, the water flow on the side of the filter screen 7 closer to the water flow direction is more concentrated and the water pressure is greater, which has a stronger impact on the filter screen 7. Therefore, by setting the inwardly inclined guide section 709, the impact of the water flow on the filter screen 7 can be reduced. The intercepted branches and debris can be harvested by the fishermen regularly. In order to improve the filtration effect, multiple sets of filter screens 7 can be set between the side pier 3 and the inner pier 4.

[0080] like Figure 7 As shown, the maintenance pile 8 is fixed on the base plate 1, and the maintenance gate slot 9 is surrounded by the maintenance pile 8. The gate assembly 10 is vertically and flexibly installed in the maintenance gate slot 9 for opening and closing the river channel. Figure 8 As shown, each set of maintenance piles 8 includes a guide plate 801, a clamping plate 802, a sealing plate 803, and a tie rod 804. The guide plate 801 and the clamping plate 802 are fixed to the base plate 1 by welding, and the clamping plate 802 is welded to the inner side of the side pier 3 and the inner pier 4 (e.g., Figure 7 As shown, the guide plate 801 and the clamping plate 802 are perpendicular to each other, as... Figure 7 As shown, the water flow direction is parallel to the guide plate 801, the maintenance gate slot 9 is set between two adjacent sets of clamping plates 802, and the gate assembly 10 can be inserted into the maintenance gate slot 9 in a lifting and lowering manner.

[0081] like Figure 9 The diagram shows the structure of the sealing plate 803. The sealing plate 803 includes a diagonal brace 8031, a pressing part 8032, a first locking edge 8033, a second locking edge 8034, and a connecting part 8035. There are two sets of diagonal braces 8031, arranged parallel to each other. The pressing part 8032 connects to both ends of one set of diagonal braces 8031. The first locking edge 8033 connects to the end of the pressing part 8032 away from the diagonal brace 8031. The second locking edge 8034 connects to the end of the first locking edge 8033 away from the pressing part 8032, as shown below. Figure 9 As shown, the two sets of pressing parts 8032 are perpendicular to each other, and the first locking edge 8033 and the second locking edge 8034 are arranged perpendicular to each other. In actual fixing, as... Figure 8 As shown, the two sets of pressing parts 8032 of the sealing plate 803 press against the inner side of the guide plate 801 and the clamping plate 802 respectively, while the two sets of diagonal bracing parts 8031 ​​of the sealing plate 803 are clamped between the guide plate 801 and the clamping plate 802 to prevent the guide plate 801 and the clamping plate 802 from deforming due to the impact of the water flow.

[0082] like Figure 8 As shown, there are two sets of tie rods 804, each set including a first tie rod portion 8041 and a second tie rod portion 8042. The first tie rod portion 8041 is fixed to the inner side of the guide plate 801 and the clamping plate 802. The side of the first tie rod portion 8041 away from the guide plate 801 and the clamping plate 802 abuts against the second clamping edge portion 8034, and the side of the first tie rod portion 8041 perpendicular to the guide plate 801 and the clamping plate 802 abuts against the first clamping edge portion 8033. The first clamping edge portion 8033 and the second clamping edge portion 8034 limit the first tie rod portion 8041. The second tie rod portion 8042 is integrally connected to the first tie rod portion 8041 and is inclined. The second tie rod portion 8042 is welded to the inner side of the side pier 3 and the inner pier 4.

[0083] During actual flow interception, the tie rod 804 abuts against the inner side of the guide plate 801 and the clamping plate 802, limiting the guide plate 801 and the clamping plate 802 to prevent deformation caused by the impact of the water flow. At this time, part of the sealing plate 803 abuts against the inner side of the guide plate 801 and the clamping plate 802, while the other part of the sealing plate 803 abuts against the outer side of the tie rod 804, together limiting the guide plate 801 and the clamping plate 802.

[0084] The gate assembly 10 is vertically and retractably inserted into the maintenance gate slot 9 for the flow or interception of water. For example... Figure 10 , 11 As shown, the gate assembly 10 includes a gate body 101, a baffle plate 102, a stop plate 103, an opening 104, a corner plate 105, a lifting head 106, a side water-stop assembly 107, and a main water-stop assembly 108. The gate body 101 is typically installed within the maintenance gate slot 9 and can be raised and lowered within the maintenance gate slot 9 by an external motor to open or close the channel (e.g., Figure 12 As shown, Figure 12 The view shown is a top view. The structure with cross-sections in the figure is the guide plate 801 and the clamping plate 802. The area between two adjacent sets of clamping plates 802 is the maintenance gate slot 9, which is used to accommodate the lifting and lowering gate body 101.

[0085] The baffle plate 102 is fixed to one side of the gate body 101, and the abutment plate 103 is fixed to the other side of the gate body 101, such as... Figure 11 As shown, Figure 11 The state shown is a top view of the gate assembly 10, in which the baffle plate 102 and the abutment plate 103 are arranged opposite each other on the long side of the gate body 101. When actually intercepting the water flow, the baffle plate 102 faces the direction of the water flow (in order to avoid the baffle plate 102 and the abutment plate 103 from being in contact with water for a long time and thus causing corrosion, the outer sides of the baffle plate 102 and the abutment plate 103 are painted).

[0086] An opening 104 is formed at the bottom of the gate body 101 for subsequent fixing of the main water-stop assembly 108. Angle plate 105 is fixed to the baffle plate 103, as shown below. Figure 12 As shown, the corner plate 105 is L-shaped, with one side of the L-shaped corner plate 105 fixed to the abutment plate 103, and the other side of the L-shaped corner plate 105 abutting against the guide plate 801. Figure 12 To highlight the positional relationship between the corner plate 105 and the guide plate 801, when the gate assembly 10 is actually closed or opened, the other side of the "L"-shaped corner plate 105 rests against the guide plate 801.

[0087] like Figure 11As shown, the lifting head 106 is fixed to the short side of the gate body 101, and an external motor is connected to the lifting head 106, which drives the gate body 101 to rise and fall. Figure 16 The diagram shows the structure of the lifting head 106, which includes a fixing plate 1061, a lifting plate 1062, and a lifting groove 1063. The fixing plate 1061 is fixed to the outside of the gate body 101, and the lifting plate 1062 is integrally connected to the outside of the fixing plate 1061. The lifting groove 1063 is located on the side of the lifting plate 1062 closest to the fixing plate 1061. The hook connected to the motor is hooked in the lifting groove 1063, which prevents the hook from falling off when the gate body 101 is opened.

[0088] like Figure 12 , 13 As shown, the side water-stop assembly 107 is fixed to one side of the baffle plate 102. When the gate body 101 descends, the side water-stop assembly 107 is used to seal the side wall of the clamping plate 802. The side water-stop assembly 107 includes a side pad 1071, a side pressure plate 1072, a screw 1073, and a side compression strip 1074. The side pressure plate 1072 is fixed to one side of the baffle plate 102, the side compression strip 1074 abuts against the side pressure plate 1072, and the side pad 1071 abuts against the side of the side compression strip 1074 away from the side pressure plate 1072. The screw 1073 passes through the side pad 1071, the side compression strip 1074, and the side pressure plate 1072 in sequence and is fixed to the baffle plate 102. By setting the side pad 1071, the screw 1073 can be prevented from directly contacting the side compression strip 1074 and damaging the side compression strip 1074.

[0089] The side extrusion strip 1074 includes a side fixing part 1075 and a side extrusion ball 1076. The side fixing part 1075 is fixed between the side pad 1071 and the side pressure plate 1072. The side extrusion ball 1076 is integrally connected to one side of the side fixing part 1075, such as... Figure 12 As shown, when the gate body 101 descends within the maintenance gate slot 9, the side compression ball 1076 deforms and abuts against the inner wall of the retaining plate 802 on one side of the baffle plate 102. The side compression strip 1074 is made of rubber, which utilizes the high elasticity of rubber to ensure more reliable compression (by setting the side compression ball 1076, a greater amount of compression can be provided during deformation, thereby improving the sealing effect).

[0090] like Figure 14 , 15As shown, the main water-stop assembly 108 is fixed inside the opening 104 at the bottom of the gate body 101. When the gate body 101 descends, the main water-stop assembly 108 seals the bottom of the inspection gate slot 9. The main water-stop assembly 108 includes an extension plate 1081, a bolt 1082, a nut 1083, a main pad 1084, a main compression strip 1085, and a support plate 1088. The extension plate 1081 is fixed to the bottom of the gate body 101 and located inside the opening 104. The main compression strip 1085 abuts against the bottom of the extension plate 1081, and the main pad 1084 abuts against the side of the main compression strip 1085 away from the extension plate 1081. The bolt 1082 passes through the main pad 1084, the main compression strip 1085, and the extension plate 1081 in sequence, and is tightened by a nut 1083 on the other side. By setting the main pad 1084, the bolt 1082 can be prevented from directly contacting the main extrusion strip 1085, thus avoiding damage to the main extrusion strip 1085. After installation, the support plate 1088 is welded between the extension plate 1081 and the baffle plate 102 to improve the structural strength of the extension plate 1081 and prevent the extension plate 1081 from deforming when the main extrusion strip 1085 is extruded.

[0091] The main extrusion strip 1085 includes a main fixing part 1086 and a main extrusion ball 1087. The main fixing part 1086 is fixed between the extension plate 1081 and the main pad plate 1084. The main extrusion ball 1087 is integrally connected to the bottom of the main fixing part 1086. When the gate body 101 descends in the maintenance gate slot 9, the main extrusion ball 1087 deforms and abuts against the bottom of the maintenance gate slot 9, while the part of the bottom of the gate body 101 away from the opening 104 normally abuts against the bottom of the maintenance gate slot 9. The main extrusion strip 1085 is made of rubber, utilizing the high elasticity of rubber to ensure more reliable extrusion (by setting the main extrusion ball 1087, a larger compression amount can be provided during deformation, thereby improving the sealing effect).

[0092] During the diversion, the gate body 101 descends within the maintenance gate slot 9. During this process, the side extrusion strip 1074 deforms and presses against the inner wall of the clamping plate 802. When the gate body 101 descends to the bottom of the maintenance gate slot 9, the main extrusion strip 1085 deforms and presses against the bottom of the maintenance gate slot 9. Under the water-stopping effect of the side extrusion strip 1074 and the main extrusion strip 1085, the seal between the gate body 101 and the maintenance gate slot 9 is effectively achieved, preventing leakage of water flow in the channel.

[0093] like Figure 1As shown, the top plate 13 is fixed to the top of the side pier 3 and the inner pier 4 to fix the axial flow motor 15. The support plate 18 is fixed between the side pier 3 and the inner pier 4 at intervals. The sleeve 19 is fitted onto the axial flow pump 16 and fixed to the support plate 18. One end of the axial flow pump 16 passes through the pump hole 12 on the cut-off wall 11 and is placed in the pump outlet section 25, while the other end of the axial flow pump 16 is placed in the pump inlet section 24. The axial flow motor 15 is fixed to the top plate 13 and connected to the axial flow pump 16 to drive the axial flow pump 16 to rotate, thereby pumping the water in the pump inlet section 24 to the pump outlet section 25 for subsequent irrigation treatment.

[0094] A buffer block 14 is provided between the axial flow motor 15 and the top plate 13 to reduce the vibration generated by the axial flow motor 15 (the axial flow pump 16 is a pump that uses the force generated by the blades of the rotating impeller to transport the liquid along the axial direction; the motor shaft of the axial flow motor 15 is connected to the impeller of the axial flow pump 16 to drive the impeller to rotate). The transition section 20 is connected to one end of the axial flow pump 16 and has a gradually decreasing diameter. The suction section 21 is integrally connected to one end of the transition section 20. By setting the transition section 20 with a gradually decreasing diameter, it is beneficial to reduce water resistance.

[0095] like Figure 17 The diagram shows the structure of the flap valve 17, which is connected to the other end of the axial flow pump 16. The flap valve 17 includes a flap plate 171, a self-opening pipe 172, a sloping surface 173, and a self-opening plate 174. When water flows normally into the axial flow pump 16, the flap valve 17 automatically opens to allow water to flow out; when the water flow is stopped, the flap valve 17 automatically closes to prevent external impurities from entering the axial flow pump 16 and thus clogging it.

[0096] The flap 171 is fixed to the end of the axial flow pump 16, and the self-starting pipe 172 is integrally connected to the flap 171. The side of the self-starting pipe 172 away from the flap 171 has an inclined surface 173 facing outward. The self-starting plate 174 is pivotally mounted on the top of the flap 171 and rests on the inclined surface 173 under its own weight. Because the inclined surface 173 is inclined, under normal circumstances, the self-starting plate 174 is tightly pressed against the inclined surface 173, which can prevent external impurities from entering the axial flow pump 16. When irrigating or draining, water flows into the axial flow pump 16. Under the action of the pivot, the water flows up the self-starting plate 174 and flows from the axial flow pump 16 into the pump inlet section 25.

[0097] The present invention's integrated filtration and interception pumping station filters the water flow in the outer river section 22 by setting up a debris-blocking channel 6 and a debris-blocking grid 7 between the side pier 3 and the inner pier 4, thereby intercepting suspended solids such as branches and weeds in the water flow; by setting up a lifting gate assembly 10 in the maintenance gate slot 9, the opening and closing of the river channel and channel can be realized, thereby achieving reasonable control of irrigation volume; finally, the pumping assembly pumps the water in the pumping section 24 to the pumping section 25 to complete farmland irrigation and river regulation.

They should not be construed as limiting the scope of protection of the present invention. All equivalent changes or modifications made in accordance with the spirit and essence of the present invention should be covered within the scope of protection of the present invention.
