Description

Technical Field

[0001] This invention relates to the field of drainage control system technology, and in particular to a drainage system and drainage control method for water conservancy projects. Background Technology

[0002] Water conservancy projects are engineering projects constructed to control and regulate surface water and groundwater in nature to achieve the purpose of eliminating harm and promoting benefits. They are an indispensable and valuable resource for human production and life. However, the natural state of water does not fully meet human needs. Only by constructing water conservancy projects can we control water flow, prevent floods, and regulate and distribute water to meet the needs of people's lives and production. Water conservancy projects require the construction of different types of hydraulic structures such as dams, dikes, spillways, sluices, intakes, canals, ferries, rafts, and fishways to achieve their goals. Drainage systems are usually used in water conservancy projects to filter impurities from the water and better control the water body. Existing drainage systems are generally constructed simultaneously with water conservancy projects to adapt to different application scenarios of water conservancy projects. Therefore, they cannot be moved. Once they reach the end of their service life, they must be demolished, rebuilt, or renovated and maintained, resulting in high renovation costs.

[0003] Currently, Chinese invention patent CN114892608B discloses a drainage device for water conservancy projects, comprising: a drainage mechanism 1; a drainage mechanism 2, snapped onto one side of the drainage mechanism 1; a drainage mechanism 3, snapped onto the other side of the drainage mechanism 1; a fixing component 1, snapped onto the side of the drainage mechanism 2 away from the drainage mechanism 1; a fixing component 2, snapped onto the side of the drainage mechanism 3 away from the drainage mechanism 1; a cover plate 1, fixedly installed on the upper end of the drainage mechanism 1 for protection; a cover plate 2, fixedly installed on the upper end of the drainage mechanism 2 for protection; and a cover plate 3, fixedly installed on the upper end of the drainage mechanism 3 for protection.

[0004] Existing inventions adapt to different widths of water conservancy projects by setting up multiple sets of detachable drainage mechanisms. Individual components can be replaced when damaged, reducing capital investment and extending the overall service life. However, this drainage device filters or purifies water by installing baffles within the drainage structure, and requires periodic baffle replacement to maintain filtration effectiveness. This approach is problematic because, firstly, when there are many or large impurities in the water, the baffles are easily clogged, significantly shortening the replacement cycle and increasing labor costs. Secondly, maintenance personnel cannot accurately assess the clogging status of the baffles, and relying on periodic baffle replacement to maintain filtration effectiveness is insufficient to respond quickly to significant changes in water quality in water conservancy projects, thus affecting drainage efficiency. Therefore, improvements are necessary. Summary of the Invention

[0005] The primary objective of this invention is to provide a drainage system for water conservancy projects, which has the advantages of good filtration effect, high drainage efficiency, and low labor cost.

[0015] The second objective of this invention is to provide a drainage control method for water conservancy projects, which has the advantages of good filtration effect, high drainage efficiency, and low labor cost.

[0016] The above-mentioned technical objective of this invention is achieved through the following technical solution: a drainage control method for water conservancy projects, applying a water conservancy project drainage system as described in any of the above technical solutions; comprising:

[0017] Step 1: First, the water impurity crushing component crushes the impurities in the water. Then, the water after impurity crushing is fed into the drainage mixing and pressurizing component for mixing and pressurization. When the drainage mixing and pressurizing component stores enough water, the water is fed into the drain pipe.

[0018] Step 2: Water containing impurities enters the drain and passes through the filter cartridge to remove the impurities. After filtration, the water is collected in the main collection pipe after passing through the distribution pipe and then discharged.

[0019] Step 3: After filtration, impurities remain in the filter cartridge. When the amount of impurities in the filter cartridge reaches a certain level, the rotating and flipping component replaces the filter cartridge with a new one between the drain outlet and the manifold for further impurity filtration. The filter cartridge with impurities flips during the transport process to remove the impurities and prepares to re-enter between the drain outlet and the manifold for further impurity filtration.

[0020] In summary, the present invention has the following beneficial effects:

[0021] 1. An impurity crushing component and a drainage mixing and pressurizing component are installed. Water containing impurities enters the impurity crushing component, where the impurities are crushed to prevent large impurities from clogging the drain pipe. The mixture of crushed impurities and water enters the drainage mixing and pressurizing component for storage. The component continuously stirs and mixes the water to prevent impurities from settling and clogging the drain pipe. When the water in the mixing and pressurizing cylinder reaches a certain level, a pressurizing pump increases the pressure, thereby increasing the drainage speed. The drain pipe is designed with a curved structure, allowing the pressurized water to enter at a high flow rate. When the water passes through the lowest point of the drain pipe, some of it is filtered and discharged through the drain outlet. Due to differences in impurity size, larger impurities are discharged through the drain outlet located at the front of the drain pipe, while smaller impurities are discharged through the drain outlet located at the rear of the drain pipe. To ensure all impurities are discharged through the drain outlet, the height difference between the highest and lowest points of the adjacent drain pipe gradually increases along the drainage direction. When the water flows to the rear of the drain pipe, its kinetic energy decreases, preventing it from breaking through the highest point. This allows impurities and water to be filtered and discharged from the final drain outlet, thus dividing the water into several segments for filtration and discharge, preventing water from concentrating in one drain outlet and causing blockage. At the same time, an arc-shaped water guide block is installed at the rear end of the drain outlet along the drainage direction. When the water flows into the arc-shaped water guide block, its direction of movement changes, moving along the tangent of the arc-shaped water guide block. This allows the water to be transported along the drain pipe, thereby dispersing the filtration pressure of the filter cylinder at the front of the drain pipe. This allows the water to be filtered and discharged sequentially through the drain outlet at the rear of the drain pipe, preventing blockage and improving drainage efficiency.

[0022] 2. A filter cartridge is installed between the drain outlet and the manifold using a rotating and flipping assembly. Water draining from the drain outlet passes through the filter cartridge and enters the manifold, eventually converging into the main manifold for discharge. Filtered impurities remain in the filter cartridge. When a pressure sensor detects that the weight of impurities in the filter cartridge has reached a certain level, the rotating and flipping assembly replaces the filter cartridge between the drain outlet and the manifold for further filtration. This allows for rapid response even when there are many impurities in the water or significant changes in water quality, eliminating the need for manual replacement, improving drainage efficiency, and reducing costs. The system also includes a flipping guide groove, comprising a fixed flipping guide cylinder and a rotating cylinder. Several rotatable rotating and flipping seats are arranged circumferentially on the rotating cylinder. A set of flipping guide holes is formed on the flipping guide cylinder, cooperating with guide blocks to form a flipping guide groove. An arc-shaped connecting block is also provided on the rotating and flipping seats. The rotating drum drives the rotating rotating seat to the position of the rotating guide groove. The rotating guide wheel at the front end along the rotation direction first moves through the guide groove into the rotating groove. Then, the rotating rod and the arc-shaped connecting block rotate around the axis of the rotating guide wheel until another rotating guide wheel comes into contact with and rolls at the bottom of the rotating guide drum. Finally, the initial rotating guide wheel follows the rotation of the rotating drum and slides out of the rotating guide groove through the other guide groove. The rotating guide groove realizes the exchange of the front and rear positions of the two rotating guide wheels, thereby realizing the rotation of the rotating rotating seat. When the rotating rotating seat rotates 180 degrees, it drives the filter cylinder to rotate 180 degrees. Due to gravity, the second filter cylinder causes the impurities to fall until they come into contact with the limit block and stop. Due to inertia, the impurities in the second filter cylinder detach from the second filter cylinder and fall into the collection frame for collection. Only the impurities in the collection frame need to be collected periodically, which greatly improves the filtration effect. Attached Figure Description

[0028] The present invention will be further described in detail below with reference to the accompanying drawings. Example

[0029] refer to Figures 1 to 4 A drainage system for a water conservancy project includes an impurity crushing component 1, a drainage mixing and pressurizing component 2, and a drainage filtration device 3 arranged along the drainage direction. The drainage filtration device 3 includes a drainage pipe 31 fixedly connected to the drainage mixing and pressurizing component 2 and several drainage outlets 32 fixedly connected to the drainage pipe 31. The drainage filtration device 3 also includes several distribution water collection pipes 33 spaced apart from the drainage outlets 32 and a main water collection pipe 34 connecting the distribution water collection pipes 33. Between the drainage outlets 32 and the distribution water collection pipes 33, several filter cylinders 36 for filtering impurities are arranged based on a rotating and flipping component 35. Water draining from the drainage outlets 32 enters the distribution water collection pipes 33 after being filtered by the filter cylinders 36 and finally collects in the main water collection pipe 34 for discharge. The rotating and flipping component 35 can replace the filter cylinders 36 with impurity-free filter cylinders 36 when the impurities in the filter cylinders 36 reach a certain level, thereby avoiding the need for manual replacement when there are many impurities in the water or when the water quality of the water conservancy project changes significantly. This improves drainage efficiency and reduces costs.

[0030] refer to Figures 1 to 2Specifically, the drain pipe 31 has a curved structure, and the height difference between the highest and lowest points of adjacent drain pipe 31 gradually increases along the drainage direction. The drain outlet 32 ​​is fixedly connected to the lowest point of the drain pipe 31. The drain pipe 31 is curved, and water pressurized by the drainage mixing and pressurizing component 2 enters the drain pipe 31 at a high flow rate. When the water passes the lowest point of the drain pipe 31, some water is filtered and discharged through the drain outlet 32. Due to differences in impurity size, larger impurities are discharged through the drain outlet 32 ​​located at the front of the drain pipe 31, while smaller impurities are discharged through the drain outlet 32 ​​located at the rear of the drain pipe 31. To ensure that all impurities are discharged through the drain outlet 32, the height difference between the highest and lowest points of adjacent drain pipe 31 gradually increases along the drainage direction. When the water flows to the drain outlet 31... The kinetic energy at the rear of the water pipe 31 decreases, preventing it from breaking through the highest point of the drain pipe 31. This causes impurities and water to be filtered and discharged from the drain outlet 32 ​​at the very end, thus achieving segmented filtration and discharge of water in several parts, preventing water from concentrating in one drain outlet 32 ​​and causing blockage. An arc-shaped water guide block 37 is fixedly provided at the rear end of the drain pipe 31 along the drainage direction at the drain outlet 32 ​​to ensure smooth drainage along the direction of the drain pipe 31. When the water flow touches the arc-shaped water guide block 37, the direction of water flow changes, moving along the tangent of the arc-shaped water guide block 37, allowing the water to be transported along the drain pipe 31. This disperses the filtration pressure of the filter cylinder 36 at the front of the drain pipe 31, allowing the water to be filtered and discharged sequentially through the drain outlet 32 ​​at the rear of the drain pipe 31, avoiding blockage and improving drainage efficiency.

[0031] refer to Figures 2 to 4Specifically, the rotating and flipping assembly 35 includes a fixed base 351 and a mounting rod 352 fixedly connected to the base 351 in the vertical direction. A flipping guide cylinder 353 is coaxially fixedly connected to the mounting rod 352, and a rotating cylinder 354 and a rotary motor 355 for driving the rotating cylinder 354 to rotate are coaxially rotatably connected to the mounting rod 352. The flipping guide cylinder 353 and the rotating cylinder 354 are coaxially arranged, and the outer shaft wall of the flipping guide cylinder 353 and the inner shaft wall of the rotating cylinder 354 are spaced apart by a certain distance. At least four rotating and flipping seats 356 for mounting the filter cylinder 36 are evenly rotatably connected to the rotating cylinder 354 in the circumferential direction, preferably six. The rotating and flipping seats 356 rotate with the rotating cylinder 354. The rotating rotating seat 356 is rotated during the process. A rotating component 357, which cooperates with the rotating guide cylinder 353 to achieve the rotation, is fixedly mounted on the rotating rotating seat 356. A set of rotating guide holes 3531 are symmetrically opened on the rotating guide cylinder 353. A guide block 3532, which cooperates with the rotating guide holes 3531, is fixedly connected to the mounting rod 352 based on a connecting rod. The rotating guide holes 3531 and the guide block 3532 combine to form a rotating guide groove 3533 that cooperates with the rotating component 357 to achieve the rotation of the rotating rotating seat 356. The rotating guide groove 3533 includes symmetrically arranged guide grooves 3534 and a rotating groove 3535 disposed between and communicating with the guide grooves 3534. The rotating component 357 includes a rotating rod 357 fixedly connected to the rotating rotating seat 356. 571 and an arc-shaped connecting block 3572 fixedly connected to the rotating rod 3571 and coinciding with the axis of the flipping guide cylinder 353. A flipping guide wheel 3573, which mates with the flipping guide groove 3533, is symmetrically connected to both ends of the arc-shaped connecting block 3572 along the rotation direction. When the rotating cylinder 354 drives the rotating flipping seat 356 to the position of the flipping guide groove 3533, the flipping guide wheel 3573 at the front end along the rotation direction first moves through the guide groove 3534 into the flipping groove 3535. Then, the rotating rod 3571 and the arc-shaped connecting block 3572 rotate around the axis of the flipping guide wheel 3573 until another flipping guide wheel 3573 abuts against and rolls on the bottom of the flipping guide cylinder 353, finally completing the initial flipping. Guide wheel 3573 follows the rotation of rotating cylinder 354 and slides out of flipping guide groove 3533 through another guide groove 3534. The flipping guide groove 3533 allows the two flipping guide wheels 3573 to exchange positions, thus flipping the rotating flipping seat 356. A pressure sensor 3574 is fixedly connected between rotating rod 3571 and rotating flipping seat 356 to detect the weight of impurities inside filter cartridge 36, thereby controlling the rotation of rotating cylinder 354 and enabling filter cartridge 36 replacement. When pressure sensor 3574 senses that the weight of impurities inside filter cartridge 36 reaches a certain level, rotating flipping assembly 35 controls rotating cylinder 354 to replace the filter cartridge 36 with a new one, positioned between drain outlet 32 ​​and manifold 33 for impurity filtration.This design allows for rapid response even when there are many impurities in the water or significant changes in water quality in water conservancy projects, eliminating the need for manual replacement, thus improving drainage efficiency and reducing costs. The filter cartridge 36 includes a first filter cartridge 361 fixedly connected to a rotating and flipping base 356 and a second filter cartridge 362 slidably connected within the first filter cartridge 361. An impurity collection frame is provided on the base 351. A limiting block 363 is fixedly provided at the top of the first filter cartridge 361 to block the second filter cartridge 362. The diameter of the filter holes on the second filter cartridge 362 is smaller than the diameter of the filter holes on the first filter cartridge 361, allowing impurities to accumulate inside the second filter cartridge 362. When the rotating and flipping base 356 rotates the filter cartridge 36, gravity causes the impurities in the second filter cartridge 362 to fall until they reach the limiting block 363 and stop. Due to inertia, the impurities inside the second filter cartridge 362 detach and fall into the collection frame for collection. Only periodic cleaning of the collection frame and reverse cleaning are required.

[0032] refer to Figures 1 to 2 Specifically, the impurity crushing component 1 is positioned higher than the drainage mixing and pressurizing component 2. The impurity crushing component 1 includes a fixed crushing cylinder 11 and several impurity crushing rods 12 that are rotatably connected to the crushing cylinder 11 in a vertical direction. Several crushing blades 13 are fixedly provided on the impurity crushing rods 12. Several crushing motors 14 for driving the impurity crushing rods 12 to rotate are fixedly provided on the crushing cylinder 11. A water inlet pipe 15 for connecting to a water conservancy project is provided at the top of the crushing cylinder 11. A first connecting pipe 16 for connecting to the drainage mixing and pressurizing component 2 is provided at the bottom of the crushing cylinder 11. After the water containing impurities enters the impurity crushing component 1, the impurities are crushed, thereby avoiding blockage of the drainage pipe 31 by large impurities.

[0033] refer to Figures 1 to 2Specifically, the drainage mixing and pressurizing assembly 2 includes a fixedly installed mixing and pressurizing cylinder 21 and a mixing rod 22 rotatably connected to the mixing and pressurizing cylinder 21 in a vertical direction. Several mixing blocks 23 are fixedly installed on the mixing rod 22. A mixing motor 24 for driving the mixing rod 22 to rotate and a pressurizing pump 25 for pressurizing are fixedly connected to the mixing and pressurizing cylinder 21. A second connecting pipe 26 for connecting to the drainage pipe 31 is fixedly installed at the bottom of the mixing and pressurizing cylinder 21. The mixture of pulverized impurities and water enters the drainage mixing and pressurizing assembly 2 for storage. The water is constantly stirred and mixed to prevent impurities from settling at the bottom and causing blockage in the drain pipe 31. When the water in the mixing and pressurizing cylinder accumulates to a certain level, the pressurizing pump 25 increases the pressure of the water in the mixing and pressurizing cylinder to a certain level, thereby increasing the drainage speed and allowing the water to flow along the drain pipe 31 as much as possible. This allows the water to be filtered and discharged in several sections, preventing the water from concentrating in one drain outlet 32 ​​and causing blockage. Switch valves 27 are fixedly installed on both the first connecting pipe 16 and the second connecting pipe 26. During pressurization, the switch valves 27 are closed to avoid affecting the kinetic energy of the water and reduce the risk of blockage. Example

[0034] A drainage control method for a water conservancy project, using a drainage system for a water conservancy project as shown in Embodiment 1 above, includes:

[0035] Step 1: First, the water impurity crushing component 1 crushes the impurities in the water. Then, the water after impurity crushing is input into the drainage mixing and pressurizing component 2 for mixing and pressurization. When the drainage mixing and pressurizing component 2 stores enough water, the water is input into the drain pipe 31.

[0036] Step 2: Water containing impurities enters the drain outlet 32 ​​and passes through the filter cylinder 36 to filter out the impurities in the water. After filtration, the water is collected in the main collection pipe 34 after passing through the distribution water pipe 33 and then discharged.

[0037] Step 3: After filtration, the impurities remain in the filter cylinder 36. When the amount of impurities in the filter cylinder 36 reaches a certain level, the rotating flipping component 35 replaces the filter cylinder 36 with a new one between the drain outlet 32 ​​and the water distribution pipe 33 to filter the impurities. The filter cylinder 36 with impurities flips during the conveying process to export the impurities and prepares to re-enter between the drain outlet 32 ​​and the water distribution pipe 33 for impurity filtration.

[0038] This specific embodiment is merely an explanation of the present invention and is not intended to limit the invention. After reading this specification, those skilled in the art can make inventive modifications to this embodiment as needed, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.

5. A drainage control method for a water conservancy project, employing a drainage system for a water conservancy project as described in any one of claims 1-4; characterized in that, include: Step 1: First, the impurities in the water are crushed in the water impurity crushing component (1). Then, the water after impurity crushing is input into the drainage mixing and pressurizing component (2) for mixing and pressurization. When enough water is stored in the drainage mixing and pressurizing component (2), the water is input into the drain pipe (31). Step 2: Water containing impurities enters the drain outlet (32) and passes through the filter cylinder (36) to filter out the impurities in the water. After filtration, the water is collected in the main collection pipe (34) after passing through the distribution water pipe (33) for collection and discharge. Step 3: After filtration, the impurities remain in the filter cylinder (36). When the amount of impurities in the filter cylinder (36) reaches a certain level, the rotating flipping component (35) replaces the new filter cylinder (36) between the drain outlet (32) and the water distribution pipe (33) to filter the impurities. The filter cylinder (36) with impurities flips during the transportation process to export the impurities and prepares to re-enter between the drain outlet (32) and the water distribution pipe (33) for impurity filtration.
