Description

Technical Field

[0001] This invention relates to the field of drainage canal technology, specifically to an automated drainage canal for water conservancy projects. Background Technology

[0002] In the field of water conservancy engineering, drainage canals are key infrastructure for coping with floods and ensuring regional flood control safety. Their core function is to quickly drain accumulated water, prevent backflow of water, and prevent regional flooding. With the acceleration of urbanization and the frequent occurrence of extreme weather, traditional drainage canals have gradually exposed many technical defects and are unable to meet the needs of modern automated drainage.

[0003] Existing drainage channels mostly adopt a single-channel drainage mode, which has limited diversion capacity. When encountering heavy rainfall or concentrated water flow, the excessive drainage pressure can easily lead to water flow congestion and even cause the channel to overflow. At the same time, a large amount of floating debris (such as branches, garbage, weeds, etc.) mixed in natural water bodies can easily accumulate in the drainage channels, which can not only block the drainage channels and reduce drainage efficiency, but also damage subsequent water conservancy facilities.

[0004] To address the problem of floating debris clogging, some drainage channels have been equipped with simple filtration structures. However, these structures are mostly fixed installations with a single pore size, making it difficult to achieve multi-stage precise filtration. Furthermore, after prolonged use, debris easily accumulates on the surface of the filter components, requiring frequent manual cleaning, resulting in high maintenance costs and poor safety. In addition, the existing drainage channels lack a coordinated and automated control mechanism for diversion and filtration functions, relying heavily on manual operation and adjustment. This results in slow response times and an inability to dynamically adjust the operating status based on real-time water accumulation and pollutant levels, severely impacting drainage efficiency and water purification effectiveness. Summary of the Invention

Detailed Implementation

[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0035] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present application.

[0036] Please refer to Figures 1 to 7 An automated drainage canal for water conservancy projects includes: a drainage canal body 1; the automated drainage canal for water conservancy projects also includes: a diversion mechanism disposed on both sides and inside the drainage canal body 1; and a filtration mechanism disposed inside the drainage canal body 1.

[0037] This embodiment provides an automated drainage canal for water conservancy projects. Its core includes a drainage canal body 1, as well as a diversion mechanism and a filtration mechanism integrated on the body. The mechanisms work together to achieve efficient drainage and water purification functions.

[0038] An automated drainage canal for water conservancy projects further includes: a diversion mechanism set on both sides and inside the drainage canal body 1. The diversion mechanism includes a plurality of diversion pipes 2 equidistantly connected on both sides of the drainage canal body 1. The ends of the diversion pipes 2 are connected to a diversion channel 3. A flow-blocking plate 6 is set inside the drainage canal body 1. The diversion mechanism is used for rapid diversion of water in the drainage canal body 1.

[0039] Furthermore, the diversion mechanism also includes several sets of symmetrical blocks 4 symmetrically and fixedly installed on the main body 1 of the drainage channel. Every four symmetrical blocks 4 form a group, and a fixing strip 5 is snapped between the fixing blocks in one group. The fixing strip 5 is fixedly connected to the flow-blocking plate 6. The flow-blocking plate 6 is made of rubber, and its width is greater than the width of the main body 1 of the drainage channel. The flow-blocking plate 6 is installed at an angle.

[0040] During the assembly of the drainage canal body 1, the diversion mechanism is installed first. Several diversion pipes 2 are installed on both sides of the drainage canal body 1 according to a pre-designed layout. The ends of each diversion pipe 2 are connected to a corresponding diversion channel 3, forming the main diversion channel. Then, a flow-blocking plate 6 is installed inside the drainage canal body 1. During installation, several sets of symmetrical blocks 4 are symmetrically fixed to the drainage canal body 1. Each set of symmetrical blocks 4 consists of four blocks. Fixing strips 5 are snapped between the same set of symmetrical blocks 4, and then the flow-blocking plate 6 is fixedly connected to the fixing strips 5. Because the flow-blocking plate 6 is made of rubber and its width is greater than the width of the drainage canal body 1, the flow-blocking plate 6 is assembled according to a pre-designed tilt angle to ensure it fits tightly against the port of the drainage canal body 1, achieving reliable flow blocking and diversion effects.

[0041] An automated drainage canal for water conservancy projects further includes: a filtration mechanism installed inside the drainage canal body 1. The filtration mechanism includes a screen 9 installed inside the drainage canal body 1. A screen 10 is fixed and symmetrically arranged on the bottom side wall of the screen 9. The screen 10 is arranged at a relative inclination. A screen 3 15 is arranged on one side of the screen 10. A pulling component is arranged between the screen 10 and the screen 3 15. The filtration mechanism is used to filter floating objects in the water.

[0042] Furthermore, the pulling component includes a first groove 7 symmetrically arranged within the drainage channel body 1. A slider 8 is slidably arranged within the first groove 7, with opposite faces of the slider 8 fixedly connected to a screen 9. A fixed seat 11 is symmetrically arranged on the screen 9, and a connecting rod 12 is fixedly arranged between the fixed seats 11. A second groove 13 is symmetrically arranged within the drainage channel body 1, and a sliding strip 14 is slidably arranged within the second groove 13. The sliding strip 14 is fixedly connected to a third screen 15, and a connecting strip 16 is fixedly arranged above the third screen 15. A second fixed seat 17 is symmetrically and fixedly arranged on the connecting strip 16, and a connecting rod 18 is fixedly arranged between the second fixed seats 17.

[0043] The drainage canal body 1 is fixedly and symmetrically equipped with square rods 19, and fixed rods 20 are fixedly installed between opposite faces of the square rods 19. A rotating rod 21 is rotatably mounted on the fixed rod 20, and an external drive motor is connected to the rotating rod 21. One end of the rotating rod 21 is rotatably connected to connecting rod 12. The end of the rotating rod 21 away from connecting rod 12 is rotatably connected to connecting rod 18.

[0044] Next, the filtration mechanism is assembled. Screen 19 is installed at a preset position inside the drainage channel body 1, and screen 20 is symmetrically fixed at the bottom of the side wall of screen 19. The two sets of screen 210 are arranged in a relatively inclined direction. Screen 315 is set on one side of screen 210, and a pulling component is installed between screen 210 and screen 315. The assembly process of the pull assembly is as follows: A sliding groove 7 is symmetrically opened inside the drainage channel body 1. The slider 8 is slidably embedded in the sliding groove 7, so that the opposite face of the slider 8 is fixedly connected to the screen 9. Fixing seats 11 are symmetrically installed on the screen 9, and connecting rod 12 is fixed between the two fixing seats 11. A sliding groove 2 13 is symmetrically opened inside the drainage channel body 1. The sliding strip 14 is slidably embedded in the two sets of sliding grooves 2 13, so that the sliding strip 14 is fixedly connected to the screen 3 15. A connecting strip 16 is fixed above the screen 3 15. Fixing seats 2 17 are symmetrically fixed on the connecting strip 16, and connecting rod 2 18 is fixed between the two fixing seats 2 17.

[0045] Finally, the assembly of the drive-related components is completed: square rods 19 are symmetrically fixedly installed on the main body 1 of the drainage canal, and a fixing rod 20 is fixedly installed between the opposite faces of the two sets of square rods 19. The rotating rod 21 is rotatably assembled onto the fixing rod 20, and the rotating rod 21 is associated with the external drive motor. At the same time, one end of the rotating rod 21 is rotatably connected to the connecting rod 12, and the other end is rotatably connected to the connecting rod 18, thus completing the assembly of the entire drainage canal.

[0046] In summary, the working principle of this invention is as follows:

[0047] This automated drainage canal achieves an automated process of drainage and water filtration through the coordinated operation of a diversion mechanism and a filtration mechanism. The specific working principle is divided into a diversion stage and a filtration stage.

[0048] When flooding occurs and a large amount of water accumulates in the drainage channel 1, the diversion mechanism takes effect first. Initially, the baffle plate 6, due to its tilted installation angle and the characteristics of its rubber material, fits tightly against the port of the drainage channel 1, blocking the water. As the water volume increases, the water flow impacts the baffle plate 6. Because the baffle plate 6 is fixedly connected to the fixing strip 5, and the fixing strip 5 is engaged between the symmetrical blocks 4, this connection structure ensures that the baffle plate 6 maintains a stable tilted posture under the impact of the water flow, preventing displacement. At this time, the baffle plate 6 guides some water to flow to both sides of the drainage channel 1 through its tilt angle, allowing the water to enter the pre-set diversion pipe 2, and then be guided into the diversion channel 3 through the diversion pipe 2, achieving rapid water diversion, effectively reducing the drainage pressure of the drainage channel 1, and preventing drainage problems caused by excessive water volume.

[0049] While the water is being diverted, the water entering the main channel of the drainage canal 1 flows through the filtration mechanism to filter floating debris. The water first contacts the relatively inclined screen 2 10, whose inclined structure can initially intercept larger floating debris while guiding the water towards screen 1 9. The water then flows through screen 1 9, which further filters medium-sized floating debris. During this process, an external drive motor starts, causing the rotating rod 21 to rotate around the fixed rod 20. Since one end of the rotating rod 21 is rotatably connected to connecting rod 1 12 and the other end is rotatably connected to connecting rod 2 18, the rotation of the rotating rod 21 synchronously drives connecting rod 1 12 and connecting rod 2 18 to reciprocate.

[0050] The reciprocating motion of connecting rod 12 drives the fixedly connected screen 9 to move. Since screen 9 is slidably engaged with slide groove 7 via slider 8, slider 8 reciprocates within slide groove 7, thereby causing screen 9 to reciprocate up and down or translate along slide groove 7. This movement prevents floating debris from accumulating on the surface of screen 9, ensuring smooth filtration. Simultaneously, the reciprocating motion of connecting rod 18 drives the connecting bar 16 to move, which in turn drives screen 15 to move. Since screen 15 is slidably engaged with slide groove 13 via sliding bar 14, sliding bar 14 reciprocates within slide groove 13, thereby causing screen 15 to reciprocate up and down or translate along slide groove 13. Screen 15 intercepts floating debris in the water filtered by screens 2 and 9, especially small floating objects, while its reciprocating motion also prevents it from clogging itself. Through the aforementioned multi-stage filtration and dynamic anti-clogging structure, efficient filtration of floating debris in the water is achieved, ensuring the cleanliness of the drainage water.
