However, in addition to the technical issues of interception and flood control, in actual use, there are also problems such as the riverbanks on both sides of some river channels being relatively low and having limited capacity to accommodate water flow, resulting in river water overflowing from the banks.

[0005] In view of this, this utility model is hereby proposed. Utility Model Content

[0014] Compared with the prior art, the present invention has the following advantages: 1. A flood control device for river channels in water conservancy projects. The system can automatically monitor and respond to sudden rises in water level through a water level sensor, and automatically raise the extension plate through a drive mechanism, thereby rapidly and proactively increasing the cross-sectional area of ​​the river channel, effectively improving its flood carrying capacity, fundamentally preventing floods from overflowing the river channel, and protecting the safety of life and property in the surrounding area.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0021] Please see Figure 1-5 A flood control device for a river channel in a water conservancy project includes a river embankment body 1 with an installation position on it; a flood control component, which is installed on the river embankment body 1 and is used for flood control. The flood control component includes a guide frame 2, an extension plate 21, a drive motor 22, a gear 24, and a rack 25. The guide frames 2 are symmetrically arranged on the corresponding wall surfaces of the river embankment body 1. The extension plate 21 is slidably connected to the corresponding guide frame 2. The drive motor 22 is fixedly connected to the river embankment body 1. The gear 24 is driven by the drive motor 22. The gear 24 meshes with the rack 25. The rack 25 is fixedly connected to the corresponding position of the river embankment body 1. When a rise in water level is detected, the drive motor 22 drives the gear 24 to rotate through the output end, and the gear 24 meshes with the rack 25. Through the meshing of the rack 25, the extension plate 21 is extended upward with the guide frame 2 as a guide, increasing the water level that this part of the river can withstand, and avoiding overflow due to a sudden rise in water level, which would threaten the surrounding environment and personnel safety.

[0022] The output end of the drive motor 22 is connected to the drive shaft 23 via a coupling. The gear 24 is fixedly connected to the drive shaft 23. The drive shaft 23 is rotatably connected to the river embankment body 1. Each guide frame 2 has a snap-fit ​​position. The extension plate 21 is arranged in an array and symmetrically with snap-fit ​​blocks 5. Each snap-fit ​​block 5 is slidably connected to the extension plate 21. Each snap-fit ​​block 5 is correspondingly provided with a cylinder 51. Each cylinder 51 is fixedly connected to the corresponding extension plate 21. The output end of the cylinder 51 is fixedly connected to the corresponding snap-fit ​​block 5. Each snap-fit ​​block 5 and the extension plate 21 are provided with a spring 52. The end of each spring 52 is fixedly connected to the corresponding snap-fit ​​block 5 and the extension plate 21 respectively. Each guide frame 2 is fixedly connected with a protective frame 4. Water level sensors 41 are arranged in an array between the protective frame 4 and the guide frame 2. Each water level sensor 41 is fixedly connected to the guide frame 2. When the water level rises sharply and a flood control signal is issued, the water level sensor 41 is set to monitor the water level in real time. When an emergency adjustment is needed, the drive motor 22 drives the drive shaft 23 to rotate through the output end. The drive shaft 23 drives the gear 24 to mesh with the rack 25. The rack 25 is driven to move, and the movement of the rack 25 drives the extension plate 21 to extend upward, thereby expanding the carrying capacity of the river in the installation area and preventing the water level from rising sharply and exceeding the area's carrying capacity, causing water to overflow the river and threaten the surrounding people and environment. As the extension plate 21 moves upward, the locking block 5 is pressed inward by the guide frame 2, and the locking block 5 compresses the spring 52. The spring 52 deforms and applies the force of the deformation to the locking block 5. When the extension plate 21 reaches the designated position, the locking block 5 is pushed by the spring 52 and engages with the guide frame 2, which restricts the position of the extension plate 21 and shares the force required by the gear 24 and rack 25, ensuring the stability of the lifting position of the extension plate 21. When the flood control is over, the drive motor 22 retracts the extension plate 21 through the gear 24 and rack 25. During this process, the cylinder 51 retracts the locking block 5 inward through the output end until the extension plate 21 is reset. It is worth noting that the output end of cylinder 51 can move freely when it is not running.

[0023] Among them, a lifting net 3 is provided between the extension plates 21. The end of the lifting net 3 is fixedly connected to the corresponding extension plate 21. The lifting net 3 is mesh-like. A baffle plate 31 is fixedly connected to the lifting net 3. The baffle plate 31 is arc-shaped and has water passage holes. As the extension plate 21 rises, it drives the lifting net 3 to rise as well. The lifting net 3 lifts up large impurities remaining in the river channel, preventing the accumulation of impurities from affecting the flow capacity at the bottom of the river channel. Furthermore, the shielding plate 31 blocks large impurities, keeping them on the lifting net 3. Later, they can be manually retrieved and cleaned, preventing the sedimentation of impurities caused by floods from affecting the subsequent carrying capacity of the river channel.

[0024] Working principle: When the water level rises sharply and a flood control signal is issued, the water level sensor 41 monitors the water level in real time. When emergency adjustments are needed, the drive motor 22 drives the drive shaft 23 to rotate through its output end. The drive shaft 23 drives the gear 24 to mesh with the rack 25, causing the rack 25 to move. The movement of the rack 25 drives the extension plate 21, which extends upward, thereby expanding the carrying capacity of the river channel in the installation area. This prevents the water level from rising too high and exceeding the area's carrying capacity, thus avoiding water overflowing the river channel and threatening surrounding personnel and the environment. Furthermore, as the extension plate 21 moves upward, the locking block 5 is pressed inward by the guide frame 2, compressing the spring 52. The spring 52 deforms and applies the deformation force to the locking block 5. When the extension plate 21 reaches the designated position, the locking block 5 releases its tension. Pushed by spring 52, the locking block 5 engages with the guide frame 2, restricting the position of the extension plate 21 and sharing the force required by gear 24 and rack 25, ensuring the stability of the extension plate 21's lifting position. When the flood control ends, the drive motor 22 retracts the extension plate 21 through gear 24 and rack 25. During this process, cylinder 51 retracts the locking block 5 inward through its output end until the extension plate 21 is reset. As the extension plate 21 rises, it drives the lifting net 3 to rise. The lifting net 3 lifts up large impurities remaining in the river channel, preventing the accumulation of impurities from affecting the flow capacity at the bottom of the river channel. The baffle plate 31 blocks large impurities, leaving them on the lifting net 3 for later manual dredging and cleaning, preventing the sedimentation of impurities caused by floods from affecting the subsequent carrying capacity of the river channel.
