Description

Technical Field

[0001] This application relates to the technical field of water conservancy engineering, and in particular to a water diversion canal structure. Background Technology

[0002] In agricultural irrigation, irrigation canals, as core water conveyance facilities, directly affect irrigation efficiency and farmland safety through their flow control capabilities. Currently, most mainstream irrigation canals adopt a modular structure and regulate water volume through the opening and closing of gates. However, under extreme conditions such as flood season, the existing gate control mechanism reveals significant shortcomings.

[0003] Traditional gate valves rely on manual or electromechanical adjustment, but manual adjustment is inefficient, and excessive use of mechanical automatic control will increase agricultural costs.

[0004] Furthermore, the gates of prefabricated irrigation canals typically employ a flat, straight-plate design with a fixed cross-sectional area for flow passage. When the flow rate exceeds the design threshold (e.g., 1.5 times the rated flow), the water level upstream of the gate can rise by 1.2-1.8 meters, significantly increasing the probability of canal embankment overflow. In 2022, in a southern irrigation district, insufficient flow passage through the gates during the flood season resulted in the flooding of 500 mu (approximately 33 hectares) of farmland and direct economic losses exceeding 300,000 yuan.

[0005] The connection between the gate and the channel is prone to gaps (2-5 mm wide) due to water flow impact, leading to a 20%-30% increase in leakage during the flood season. Simultaneously, the assembled interface may shift under long-term water flow erosion (an average annual displacement of 0.5-1.0 cm), further weakening the gate's flow control capability. Therefore, to address these issues, this application provides a water diversion channel structure. Utility Model Content

[0006] To address the aforementioned problems, this application provides a water diversion channel structure.

[0007] This application provides a water diversion channel structure, including a ditch module disposed in the water diversion channel. A diversion structure with a height difference between the inside of the ditch module and the bottom of the ditch module is disposed therein. The diversion structure is horizontally and movably connected to the inside of the ditch module. Water flow below the upper end of the diversion structure flows normally, while water flow above the upper end of the diversion structure is diverted to the outside of the ditch module.

[0008] By setting a diversion structure inside the ditch module, the height difference formed between the diversion structure and the bottom of the ditch module allows water flow below the combination of the platform plate and the movable plate to flow normally, while water flow above the combination of the platform plate and the movable plate will flow out through the diversion port on one side, thereby achieving convenient control of the water delivery volume of the water diversion channel.

[0009] Preferably, the diversion structure includes a platform plate fixed to the side wall of the ditch module and a movable plate sliding below the platform plate, with the movable plate and the platform plate in a transitional fit, and the height of the platform plate being greater than the bottom wall of the ditch module.

[0010] Preferably, the sidewall of the ditch module has a through groove, and the movable plate is slidably embedded in the through groove.

[0011] Preferably, the platform plate is rotatably connected to a fastening structure, which fixes the position of the movable plate.

[0012] Preferably, a through groove is formed on the side wall of the ditch module, and the through groove is located above the platform plate.

[0013] Preferably, a guide groove is provided on the outer side of the through groove for guiding the diverted water flow.

[0014] In summary, this application includes the following beneficial technical effects:

[0015] By setting a diversion structure inside the ditch module, the height difference formed between the diversion structure and the bottom of the ditch module allows water flow below the combination of the platform plate and the movable plate to flow normally, while water flow above the combination of the platform plate and the movable plate will flow out through the diversion port on one side, thereby achieving convenient control of the water delivery volume of the water diversion channel.

[0020] The following is in conjunction with the appendix Figure 1 - Figure 3 This application will be described in further detail.

[0021] Example 1:

[0022] A water diversion canal structure, referring to Figure 1 - Figure 3The ditch module 1 is set in the water diversion channel. A diversion structure with a height difference between the inside of the ditch module 1 and the bottom of the ditch module 1 is set inside the ditch module 1. The diversion structure is horizontally movable and connected to the inside of the ditch module 1. The water flow below the upper end of the diversion structure flows normally, while the water flow above the upper end of the diversion structure is diverted to the outside of the ditch module 1.

[0023] By setting a diversion structure inside the ditch module 1, the height difference formed by the diversion structure and the bottom of the ditch module 1 allows water flow below the combination of platform plate 2 and movable plate 3 to flow normally, while water flow above the combination of platform plate 2 and movable plate 3 will flow out through the diversion port 11 on one side, thereby realizing convenient control of the water supply of the water diversion channel.

[0024] The diversion structure includes a platform plate 2 fixed to the side wall of the ditch module 1 and a movable plate 3 sliding below the platform plate 2. The movable plate 3 and the platform plate 2 are fitted together. The height of the platform plate 2 is greater than the bottom wall of the ditch module 1. The bottoms of the platform plate 2 and the movable plate 3 slide together. The bottom of the movable plate 3 and the bottom of the ditch module 1 also slide together. After adjusting the position of the movable plate 3, an appropriate water flow rate can be selected. When the water level is lower than the combined height of the platform plate 2 and the movable plate 3, the water will flow through the channel between the ditch module 1 and the movable plate 3. When the water level rises and exceeds the height of the platform plate 2, the water will flow to the outside through the diversion port 11 on the side of the ditch module 1, thus completing the diversion of the water flow and ensuring that the water supply in the ditch is not excessive.

[0025] A through groove 13 is opened on the side wall of the ditch module 1, and a movable plate 3 is slidably embedded in the through groove 13. The movable plate 3 has a C-shaped structure when viewed from above, and its two free ends are slidably embedded in the through groove 13 to adjust the width of the flow channel below the ditch module 1.

[0026] A fastening structure is rotatably connected to the platform plate 2. The fastening structure fixes the position of the movable plate 3. The fastening structure includes a threaded rod 4 that passes through the platform plate 2 and a handle 5 fixed at the top of the threaded rod 4. The end of the threaded rod 4 abuts against the top of the movable plate 3 to increase the friction between them, thereby ensuring the stability of the position of the movable plate 3.

[0027] A through-slot 13 is formed on the side wall of the ditch module 1, located above the platform plate 2. The bottom end of the through-slot 13 overlaps with the top surface of the platform plate 2. After water flows over the platform plate 2, it can flow to the outside of the ditch module 1 through the through-slot 13. Due to the characteristics of the ditch module 1, the location of the ditch module 1 needs to meet the following conditions: a diversion ditch needs to be set up on one side of the through-slot 13, the original water channel needs to be cut off, and the ditch module 1 needs to be placed in this position. The ditch module 1 is installed by hoisting.

[0028] A guide groove 12 is provided on the outside of the through groove 13 for guiding the diversion water flow. The shape of the guide groove 12 is not fixed and can be customized according to the actual ditch structure. It can be a straight groove or a groove with a certain turning angle.

However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the spirit of this disclosure, and various combinations can be made to the various technical features and structures proposed in this disclosure without exceeding the protection scope of this disclosure, which is determined by the appended claims.
