Description

Canal structure Technical Field The application relates to the technical field of hydraulic engineering, in particular to a water diversion channel structure. Background In the field of agricultural irrigation, the water intake canal is used as a core water delivery facility, and the flow control capability of the water intake canal directly influences irrigation efficiency and farmland safety. The current main flow water channel mostly adopts an assembled structure and adjusts the water quantity through the opening and closing degree of the flashboard, but under the extreme working conditions such as flood season, the existing flashboard control mechanism exposes significant defects. Traditional flashboard relies on manual or electromechanical adjustment, but manual adjustment is not efficient, and excessive mechanical automatic control is adopted to increase agricultural cost. In addition, the flashboard of the assembled channel is usually designed by adopting a plane straight plate, and the area of the flow cross section is fixed. When the flow exceeds a design threshold (for example, 1.5 times of rated flow), the upstream water level of the flashboard can reach 1.2-1.8m, so that the probability of the embankment overtaking is obviously increased. In 2022, under the condition of insufficient flow of flashboard in flood season, 500 mu of farmland is flooded, and the economic loss is directly over 30 ten thousand yuan. Gaps (the width of the gaps can reach 2-5 mm) are easily generated at the joint of the flashboard and the channel due to water flow impact, so that the leakage amount in the flood season is increased by 20-30%. Meanwhile, the assembly type interface can displace (the displacement is 0.5-1.0cm in year) under long-term water flushing, so that the flow control capability of the flashboard is further weakened. Accordingly, to solve the above-described problems, the present application provides a canal structure. Disclosure of utility model In order to solve the problems, the application provides a water channel structure. The application provides a water channel structure, which comprises a channel module arranged in a water channel, wherein a diversion structure with a height difference is arranged at the inner side of the channel module and at the bottom of the channel module, the diversion structure is horizontally and movably connected at the inner side of the channel module, water flow lower than the upper end of the diversion structure normally flows, and water flow higher than the upper end of the diversion structure is diverted to the outside of the channel module. Through setting up the reposition of redundant personnel structure in the inboard of ditch module, utilize the difference in height that the reposition of redundant personnel structure and ditch module bottom formed for the rivers that are less than platform board and fly leaf combination can normally flow, and the rivers that are higher than platform board and fly leaf combination can flow through the shunt outlet of one side, thereby realize the convenient control to the water delivery volume of water channel. Preferably, the diversion structure comprises a platform plate fixed on the side wall of the ditch module and a movable plate sliding below the platform plate, the movable plate and the platform plate are in transition fit, and the height of the platform plate is larger than that of the bottom wall of the ditch module. Preferably, the side wall of the ditch module is provided with a through groove, and the movable plate is slidably embedded in the through groove. Preferably, the platform plate is rotatably connected with a fastening structure, and the fastening structure fixes the position of the movable plate. Preferably, the side wall of the ditch module is provided with a through groove, and the through groove is positioned above the platform plate. Preferably, a guide groove is arranged at the outer side of the through groove and used for guiding split water flow. In summary, the application has the following beneficial technical effects: Through setting up the reposition of redundant personnel structure in the inboard of ditch module, utilize the difference in height that the reposition of redundant personnel structure and ditch module bottom formed for the rivers that are less than platform board and fly leaf combination can normally flow, and the rivers that are higher than platform board and fly leaf combination can flow through the shunt outlet of one side, thereby realize the convenient control to the water delivery volume of water channel.
