[0002] Hydraulic engineering projects are engineering works constructed to control and regulate surface water and groundwater in nature to achieve the goals of mitigating harm and promoting benefits. They are also called water engineering projects. The construction of hydraulic engineering projects controls water flow, prevents floods, and regulates and distributes water to meet the water needs of people's lives and production. Hydraulic engineering projects require the construction of various types of hydraulic structures, such as dams, dikes, spillways, sluice gates, intakes, canals, ferries, raft channels, and fishways, to achieve their objectives.

[0003] Chinese Patent No. CN211873243U discloses a drainage device for water conservancy projects, including a base and a pipe body. A water pump is connected to the lower part of the right side wall of the pipe body. A cover is threaded to the top of the pipe body. A support rod is fixed at the center of the inner wall of the cover. A filter plate is rotatably connected to the bottom end of the support rod. Multiple connecting rods are fixed to the support rod. A connecting ring is fixed to the outer end of the connecting rod. Multiple bristles are evenly fixed to the outer side of the connecting ring.

[0004] The drainage system of water conservancy projects uses filter plates to separate solid impurities in the water, preventing these impurities from damaging the water pump.

[0005] The drainage device in the prior art solves the technical problem that the filter plate is usually fixed and difficult to remove, which may cause the filter plate to become clogged during long-term use, resulting in reduced drainage efficiency. In the actual research and development process, the applicant has developed another new technical solution to solve the above-mentioned technical problem. Summary of the Invention

[0006] The purpose of this invention is to provide a drainage device for water conservancy projects, which has the advantage of cleaning filter plates, reducing filter plate blockage and thus reducing drainage efficiency.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This invention provides a drainage device for hydraulic engineering, including a base and a treatment box mounted on the base. The treatment box is equipped with a partition for dividing the interior into a first zone and a second zone. An inlet pipe with a valve is located on the upper left side wall of the treatment box, and the inlet pipe communicates with the first zone. An outlet pipe with a valve is located on the lower right side wall of the treatment box, and the outlet pipe communicates with the second zone. A water pump is mounted on the outlet pipe. One side of the partition has an upper and lower opposing connecting groove and a flow channel, the connecting groove corresponding to the inlet pipe and the flow channel corresponding to the outlet pipe. The first area is provided with a first filter plate located between the connecting channel and the flowing water channel, and the second area is provided with a second filter plate located between the connecting channel and the flowing water channel. The processing box is provided with a first driving member for driving the first filter plate to move vertically up and down in the first area, and a second driving member for driving the second filter plate to move vertically up and down in the second area. When the first filter plate moves vertically upward to between the water inlet pipe and the connecting channel, the first filter plate is provided with a connecting member for connecting the water inlet pipe and the connecting channel. Both the first filter plate and the second filter plate are provided with a plurality of filter holes.

[0009] By adopting the above technical solution, during use, water flows from the inlet pipe into the area above the first filter plate. After being filtered through the various filter holes on the first filter plate, the filtered water is located below the first filter plate. Since the water flow channel corresponds to the outlet pipe, the water filtered by the first filter plate can be pumped out by opening the water pump and the valve on the outlet pipe. When the first filter plate is filtering water, the water level on the first filter plate is always lower than the connecting channel. When the first filter plate needs to be cleaned, the first drive component can be used to move the first filter plate vertically upward in the first area until the first filter plate is moved between the inlet pipe and the connecting channel. At this time, the top of the first filter plate is outside the treatment box, and then the impurities filtered out from the top of the first filter plate can be cleaned.

[0010] When the first filter plate moves between the inlet pipe and the connecting groove, the inlet pipe and the connecting groove will be connected through the connecting piece on the first filter plate. At this time, the water flowing out of the inlet pipe will flow into the connecting groove through the connecting piece, and then flow into the second filter plate in the second zone from the connecting groove. After the water is filtered through the various filter holes on the second filter plate, the filtered water is located below the second filter plate. At this time, while cleaning the first filter plate, the water can continue to be filtered through the second filter plate in the second zone without stopping the water from flowing into the inlet pipe.

[0011] After the first filter plate is cleaned and moved downwards to its initial position, the water flowing out of the inlet pipe will flow back into the area above the first filter plate. When it is necessary to clean the second filter plate, simply use the second drive to move the second filter plate vertically upwards until it is removed from the treatment box. Then clean the second filter plate that has been removed from the treatment box. It is simple and convenient to use.

At this time, the opposite side walls of the second sliding groove are in contact with the second sliding column. The processing box is provided with a driving component for simultaneously driving the first and third rotating shafts to rotate.

[0014] Preferably, the driving component includes a driven shaft coaxially disposed at one end of the first rotating shaft near the first protrusion, and the end of the driven shaft away from the first rotating shaft passes through the first protrusion and is provided with a driven gear. The end of the first protrusion away from the first rotating shaft is rotatably connected to a transmission gear that meshes with the driven gear. The end of the third rotating shaft near the fourth protrusion is coaxially provided with a driving shaft, and the end of the driving shaft away from the third rotating shaft passes through the fourth protrusion and is provided with a first sprocket. The end of the transmission gear away from the first protrusion is provided with a second sprocket, and the first sprocket and the second sprocket are connected by a chain.

At this time, one end of the rotating shaft of the first motor passes through the vertical groove, and the top of the vertical rod is fixedly connected to the bottom of the placement groove. At this time, the first cover plate is used to close the box opening above the first zone on the processing box.

[0016] Preferably, the top of the first filter plate has a groove, the bottom of the vertical rod passes vertically through the groove and is horizontally fixedly connected to a placement plate, the top of the placement plate has several cleaning columns located below the first filter plate, and each cleaning column corresponds to each filter hole on the first filter plate, a compression spring is provided between the top of the placement plate and the bottom of the first filter plate, the first protrusion, the second protrusion, the third protrusion and the fourth protrusion are all horizontally provided with baffles at the ends near the vertical rod, and the bottom ends of the four baffles are in contact with the top of the rectangular frame, and the top of the placement plate has several elongated grooves.

[0021] The beneficial effects of this invention are as follows: In use, water flows from the inlet pipe into the area above the first filter plate. After the water is filtered through the filter holes on the first filter plate, the filtered water is located below the first filter plate. Since the water trough corresponds to the outlet pipe, the water filtered by the first filter plate can be pumped out by opening the water pump and the valve on the outlet pipe. When the first filter plate is filtering water, the water level on the first filter plate is always lower than the connecting trough.

After the water is filtered through the various filter holes on the second filter plate, the filtered water is located below the second filter plate. At this time, while cleaning the first filter plate, the water can continue to be filtered through the second filter plate in the second zone without stopping the water from flowing into the inlet pipe.

[0023] After the first filter plate is cleaned and moved downwards to its initial position, the water flowing out of the inlet pipe will flow back into the area above the first filter plate. When it is necessary to clean the second filter plate, simply use the second drive to move the second filter plate vertically upwards until it is removed from the treatment box. Then clean the second filter plate that has been removed from the treatment box. It is simple and convenient to use. Attached Figure Description

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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.

[0036] A drainage device for water conservancy projects, such as Figure 1 and Figure 2The system includes a base 1 and a processing box 2 mounted on the base 1. The processing box 2 is equipped with a partition 3 that divides the interior of the processing box 2 into a first zone 4 and a second zone 5. A water inlet pipe 6 with a valve is located on the upper left side wall of the processing box 2 and is connected to the first zone 4. A water outlet pipe 7 with a valve is located on the lower right side wall of the processing box 2 and is connected to the second zone 5. A water pump 8 is mounted on the water outlet pipe 7. A connecting groove 9 and a water flow channel 10, which are vertically opposite, are opened on one side of the partition 3. The connecting groove 9 corresponds to the water inlet pipe 6, and the water flow channel 10 corresponds to the water outlet pipe 7. The first zone 4 contains a section located within the connecting groove 9. The first filter plate 12 is located between the water tank 10 and the second filter plate 13 located between the connecting groove 9 and the water tank 10 in the second zone 5. The processing box 2 is provided with a first driving member for driving the first filter plate 12 to move vertically up and down in the first zone 4. The processing box 2 is provided with a second driving member for driving the second filter plate 13 to move vertically up and down in the second zone 5. When the first filter plate 12 moves vertically upward to between the water inlet pipe 6 and the connecting groove 9, the first filter plate 12 is provided with a connecting member for connecting the water inlet pipe 6 and the connecting groove 9. Both the first filter plate 12 and the second filter plate 13 are provided with a number of filter holes 14.

[0037] like Figure 1 and Figure 2 When in use, water flows from the inlet pipe 6 into the first zone 4 above the first filter plate 12. After the water is filtered through the filter holes 14 on the first filter plate 12, the filtered water is located below the first filter plate 12. Since the water trough 10 corresponds to the outlet pipe 7, the water filtered by the first filter plate 12 can be pumped out by opening the valve on the water pump 8 and the outlet pipe 7. When the first filter plate 12 is filtering water, the water level on the first filter plate 12 is always lower than the connecting groove 9. When the first filter plate 12 needs to be cleaned, the first drive component can be used to move the first filter plate 12 vertically upward in the first zone 4 until the first filter plate 12 is moved between the inlet pipe 6 and the connecting groove 9. At this time, the top of the first filter plate 12 is outside the treatment box 2. Then the impurities filtered out from the top of the first filter plate 12 can be cleaned.

[0038] When the first filter plate 12 moves between the water inlet pipe 6 and the connecting groove 9, the water inlet pipe 6 and the connecting groove 9 will be connected through the connecting piece on the first filter plate 12. At this time, the water flowing out of the water inlet pipe 6 will flow into the connecting groove 9 through the connecting piece, and then flow into the second filter plate 13 in the second zone 5 from the connecting groove 9. After the water is filtered through the filter holes 14 on the second filter plate 13, the filtered water is located below the second filter plate 13. At this time, while cleaning the first filter plate 12, the water can continue to be filtered through the second filter plate 13 in the second zone 5 without stopping the water from flowing in from the water inlet pipe 6.

[0039] After the first filter plate 12 is cleaned and moved downward to its initial position, the water flowing out of the inlet pipe 6 will flow back into the first filter plate 12 in the first zone 4. When it is necessary to clean the second filter plate 13, simply move the second filter plate 13 vertically upward through the second drive component until the second filter plate 13 is removed from the treatment box 2. Then clean the second filter plate 13 that has been removed from the treatment box 2. It is simple and convenient to use.

[0040] like Figure 3 The connecting element includes a guide groove 15 formed on the side of the first filter plate 12 near the inlet pipe 6. Each filter hole 14 on the first filter plate 12 is located on both sides of the guide groove 15. The purpose of this arrangement is that when the first filter plate 12 moves between the inlet pipe 6 and the connecting groove 9, the guide groove 15 on the first filter plate 12 will connect the inlet pipe 6 and the connecting groove 9 (e.g., Figure 7 At this time, the water flowing out of the inlet pipe 6 will flow into the guide channel 15, and then from the guide channel 15 into the connecting channel 9, which is simple and convenient to use.

[0041] like Figure 2 and Figure 4 and Figure 5The first driving component includes a rectangular frame 16 located at the top of the processing box 2, directly above the first area 4. The top four corners of the rectangular frame 16 are respectively provided with a first protrusion 17, a second protrusion 18, a third protrusion 19, and a fourth protrusion 20. A first rotating shaft 21 rotatably connects the first protrusion 17 and the second protrusion 18; a second rotating shaft 22 rotatably connects the second protrusion 18 and the third protrusion 19; a third rotating shaft 23 rotatably connects the third protrusion 19 and the fourth protrusion 20; and a fourth rotating shaft 24 rotatably connects the fourth protrusion 20 and the first protrusion 17. The sidewall of the first filter plate 12 contacts the inner wall of the first area 4. A vertical rod 25 is vertically provided on the first filter plate 12, and four U-shaped first swing arms 26 are hinged to the sidewall of the vertical rod 25. The four first swing arms 26 are evenly distributed along the circumference of the vertical rod 25, and one side of each of the four first swing arms 26 is positioned along its length. A first groove 27 passes through the first swing arm 26. The first rotating shaft 21, the second rotating shaft 22, the third rotating shaft 23, and the fourth rotating shaft 24 are all inclined downward with one end of the second swing arm 28 located in the first area 4. The ends of the four second swing arms 28 near the vertical rod 25 are respectively located in the four first swing arms 26 and are all horizontally provided with first sliding columns 29. The two ends of the four first sliding columns 29 are all located in the first groove 27 on the first swing arm 26. At this time, the opposite side walls of the first groove 27 are in contact with the first sliding column 29. A second groove 30 is opened on one side of each of the four second swing arms 28 along the length direction of the second swing arm 28. The ends of the four first swing arms 26 away from the vertical rod 25 are all horizontally provided with second sliding columns 31 located in the second groove 30. At this time, the opposite side walls of the second groove 30 are in contact with the second sliding column 31. The processing box 2 is provided with a driving component for simultaneously driving the first rotating shaft 21 and the third rotating shaft 23 to rotate.

[0042] like Figure 2 and Figure 4 and Figure 5When it is necessary to move the first filter plate 12 vertically up and down, it is only necessary to drive the first rotating shaft 21 and the third rotating shaft 23 to rotate in opposite directions simultaneously through the driving component. At this time, the first rotating shaft 21 will drive the second swing arm 28 on the first rotating shaft 21 to rotate along the rotation axis of the first rotating shaft 21, and the third rotating shaft 23 will drive the second swing arm 28 on the third rotating shaft 23 to rotate along the rotation axis of the third rotating shaft 23. Since the four first swing arms 26 are hinged to the vertical rod 25, the first sliding pins 29 on the four second swing arms 28 are respectively located in the first sliding grooves 27 on the four first swing arms 26. The second sliding pins 31 on the four first swing arms 26 are respectively located in the second sliding grooves 30 on the four second swing arms 28. Therefore, when the driving component drives the first rotating shaft 21 and the third rotating shaft 23 to rotate in opposite directions at the same time, the vertical rod 25 can be driven to move vertically up and down through the cooperation of the four first swing arms 26, second swing arms 28, first sliding grooves 27, first sliding pins 29, second sliding grooves 30 and second sliding pins 31. At this time, the first filter plate 12 will move up and down with the vertical rod 25. At this time, the first sliding pin 29 will slide in the first sliding groove 27 and the second sliding pin 31 will slide in the second sliding groove 30.

[0043] When the first rotating shaft 21 drives the second swing arm 28 on the first rotating shaft 21 to rotate upward along the rotation axis of the first rotating shaft 21, and the third rotating shaft 23 drives the second swing arm 28 on the third rotating shaft 23 to rotate upward along the rotation axis of the first rotating shaft 21, the first filter plate 12 and the vertical rod 25 will move vertically upward.

[0044] When the first rotating shaft 21 drives the second swing arm 28 on the first rotating shaft 21 to rotate downward along the rotation axis of the first rotating shaft 21, and the third rotating shaft 23 drives the second swing arm 28 on the third rotating shaft 23 to rotate downward along the rotation axis of the first rotating shaft 21, the first filter plate 12 and the vertical rod 25 will move vertically downward, making it simple and convenient to use.

[0045] like Figure 4 The driving component includes a driven shaft 32 coaxially disposed at one end of the first rotating shaft 21 near the first protrusion 17, and the end of the driven shaft 32 away from the first rotating shaft 21 passes through the first protrusion 17 and is provided with a driven gear 33. The end of the first protrusion 17 away from the first rotating shaft 21 is rotatably connected to a transmission gear 34 that meshes with the driven gear 33. The end of the third rotating shaft 23 near the fourth protrusion 20 is coaxially provided with a drive shaft 35, and the end of the drive shaft 35 away from the third rotating shaft 23 passes through the fourth protrusion 20 and is provided with a first sprocket 36. The end of the transmission gear 34 away from the first protrusion 17 is provided with a second sprocket 37, and the first sprocket 36 and the second sprocket 37 are connected by a chain 38. The processing box 2 is provided with a first motor 39, and one end of the rotating shaft of the first motor 39 is coaxially and fixedly connected to the first sprocket 36.

[0046] like Figure 4When it is necessary to drive the first rotating shaft 21 and the third rotating shaft 23 to rotate in opposite directions, simply turn on the first motor 39. At this time, the rotating shaft of the first motor 39 drives the first sprocket 36 to rotate. The first sprocket 36 then drives the third rotating shaft 23 to rotate through the drive shaft 35. Simultaneously, the first sprocket 36 drives the second sprocket 37 to rotate through the chain 38. The second sprocket 37 drives the transmission gear 34 to rotate. The transmission gear 34 then drives the driven shaft 32 to rotate through the driven gear 33 it meshes with. The driven shaft 32 then drives the first rotating shaft 21 to rotate. The first rotating shaft 21 and the third rotating shaft 23 rotate in opposite directions, and their rotation speeds are the same. The first motor 39 is a servo motor, which is simple and convenient to use.

[0047] like Figure 1 and Figure 2 and Figure 3 A first cover plate 40 is placed on top of the processing box 2, directly above the first zone 4. The bottom of the first cover plate 40 has a placement groove 41. The rectangular frame 16, driven gear 33, transmission gear 34, first sprocket 36, and second sprocket 37 are all located within the placement groove 41. A vertical groove 42, communicating with the placement groove 41, is vertically provided on one side of the first cover plate 40, and the vertical groove 42 is connected to the bottom of the cover plate. At this time, one end of the rotating shaft of the first motor 39 passes through the vertical groove 42, and the top of the vertical rod 25 is fixedly connected to the bottom of the placement groove 41. The first cover plate 40 is used to close the opening of the processing box 2 above the first zone 4. The purpose of this arrangement is to... The first cover plate 40 reduces the amount of external impurities falling into the first zone 4. Simultaneously, because the first cover plate 40 closes the opening of the processing box 2 above the first zone 4, the rectangular frame 16, driven gear 33, transmission gear 34, first sprocket 36, and second sprocket 37 are all located within the placement slot 41. Therefore, the first cover plate 40 protects the rectangular frame 16, driven gear 33, transmission gear 34, first sprocket 36, and second sprocket 37. When the vertical rod 25 moves the first filter plate 12 vertically upwards, the first cover plate 40 will also move upwards with the vertical rod 25. At this time, the opening of the processing box 2 above the first zone 4 can be opened (e.g., Figure 6 It is simple and convenient to use.

[0048] like Figure 2 and Figure 4The top of the first filter plate 12 is provided with a groove 43. The bottom end of the vertical rod 25 passes vertically through the groove 43 and is horizontally fixedly connected to a placement plate 44. The top of the placement plate 44 is provided with several cleaning columns 45 located below the first filter plate 12, and each cleaning column 45 corresponds to each filter hole 14 on the first filter plate 12. A compression spring 46 is provided between the top of the placement plate 44 and the bottom of the first filter plate 12. The first protrusion 17, the second protrusion 18, the third protrusion 19, and the fourth protrusion 20 are all provided with baffles 47 at the end near the vertical rod 25, and the bottom ends of the four baffles 47 are in contact with the top of the rectangular frame 16. The top of the placement plate 44 is provided with several elongated grooves 48.

[0049] like Figure 2 and Figure 3 and Figure 4 After being filtered through the filter holes 14 on the first filter plate 12, water droplets fall onto the placement plate 44, and then flow from the elongated groove 48 on the placement plate 44 to the bottom of the treatment tank 2. When the vertical rod 25 moves vertically up and down, the placement plate 44 moves vertically along with the vertical rod 25. At this time, because there is a compression spring 46 between the first filter plate 12 and the placement plate 44, the placement plate 44 will drive the first filter plate 12 to move with the vertical rod 25 through the compression spring 46. When the vertical rod 25 moves vertically upward until the first filter plate 12 is moved between the inlet pipe 6 and the connecting groove 9, the guide groove 15 on the first filter plate 12 connects the inlet pipe 6 and the connecting groove 9. Figure 6 and Figure 7 and Figure 8 At this point, the top of the first filter plate 12 will be located inside the rectangular frame 16 and flush with the top of the rectangular frame 16. The top of the first filter plate 12 will then contact the bottom of the four baffles 47. Then, the vertical rod 25 continues to move upward. Since the first filter plate 12 is in contact with the bottom of the baffles 47, the first filter plate 12 will stop moving with the vertical rod 25. At this point, the placement plate 44 will gradually approach the first filter plate 12 as the vertical rod 25 moves upward. At this point, the compression spring 46 will be compressed. As the placement plate 44 gradually approaches the first filter plate 12, each cleaning column 45 on the placement plate 44 will be vertically inserted into each filter hole 14 on the first filter plate 12. At this point, the solid impurities blocking the filter holes 14 on the first filter plate 12 can be cleaned by the cleaning columns 45. It is simple and convenient to use.

[0050] like Figure 2 and Figure 4 Both the first motor 39 and the water pump 8 are provided with a first housing 49 on their outer side, and the outer surface of the first housing 49 is coated with a hydrophobic coating. The purpose of this arrangement is to protect the water pump 8 and the first motor 39 through the first housing 49, thereby improving the service life of the water pump 8 and the first motor 39.

[0051] like Figure 2 The second driving component includes a screw 50 rotatably connected to the bottom of the inner chamber of the processing box 2 and a mounting groove 51 opened at the top of the second filter plate 13. The side wall of the second filter plate 13 contacts the inner wall of the second zone 5. The top of the screw 50 passes through the mounting groove 51. A threaded cylinder 52 located above the second filter plate 13 is threadedly connected to the screw 50, and the bottom end of the threaded cylinder 52 is fixedly connected to the top of the second filter plate 13. A second motor 53 for driving the screw 50 to rotate is provided at the bottom of the outer wall of the processing box 2.

[0052] like Figure 2 When it is necessary to move the second filter plate 13 vertically upward and remove it from the processing box 2, simply turn on the second motor 53. At this time, the rotating shaft of the second motor 53 drives the screw 50 to rotate clockwise. Since the threaded cylinder 52 connected to the screw 50 is fixedly connected to the second filter plate 13, when the screw 50 rotates clockwise, it can drive the second filter plate 13 to move vertically upward through the threaded cylinder 52. Because the side wall of the second filter plate 13 is in contact with the inner wall of the second zone 5, the threaded cylinder 52 and the second filter plate 13 will not rotate with the screw 50. When the second filter plate 13 moves vertically upward out of the processing box 2, the threaded cylinder 52 will separate from the screw 50. At this time, the second filter plate 13 with the threaded cylinder 52 can be removed for cleaning. It is simple and convenient to use.

[0053] like Figure 2 The top of the threaded cylinder 52 is flush with the top of the treatment box 2, and the top of the threaded cylinder 52 is provided with a second cover plate 54, which is located above the second zone 5. At this time, the second cover plate 54 is used to close the box opening on the treatment box 2 located above the second zone 5. The purpose of this setting is to reduce the amount of external impurities falling into the second zone 5 through the second cover plate 54. When the threaded cylinder 52 and the second filter plate 13 move vertically upward, the second cover plate 54 will move upward with the threaded cylinder 52. At this time, the box opening on the treatment box 2 located above the second zone 5 can be opened, which is simple and convenient to use.

[0054] like Figure 2 The second motor 53 is provided with a second housing 55 on its outer side, and the outer surface of the second housing 55 is coated with a hydrophobic coating. The purpose of this is to protect the second motor 53 through the second housing 55 and improve the service life of the second motor 53.

[0055] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
