Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, and in particular to a diversion and drainage device for water conservancy projects. Background Technology

[0002] The purpose of diversion devices in water conservancy projects is to divert river water to where it is needed, or to divert and discharge excess river water during the rainy season to prevent flooding and to ensure the rational allocation and utilization of water resources. Existing water diversion devices mostly employ methods such as interception and obstruction to change the direction of river flow, thereby achieving the diversion function. However, this method places a significant impact on the diversion device, requiring it to possess extremely high strength to ensure stable operation. Utility Model Content

[0003] The purpose of this utility model is to provide a diversion and drainage device for water conservancy projects. This device adopts a dredging and diversion method to separate the main waterway. Part of the river water continues to flow downstream, while part of the river water is discharged through the diversion channel, thereby reducing the impact of the water flow on the device and improving the stability of the device's operation.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a water diversion and drainage device for a water conservancy project, comprising a water channel, with diversion channels respectively arranged on both sides of the water channel, the two diversion channels being staggered, and two diversion dikes arranged inside the water channel, the two diversion dikes being respectively arranged on one side of the diversion channel, the side of the diversion dike closer to the diversion channel being the diversion waterway, and the other side of the diversion channel being the main waterway; a diversion cut-off mechanism is provided at the inlet of the diversion channel, the diversion cut-off mechanism including a diversion gate and two diversion hydraulic cylinders, the diversion hydraulic cylinders being vertically arranged on both sides of the diversion channel, the diversion gate being arranged inside the diversion channel, and a connecting plate being provided on the top of the diversion gate, the connecting plate being fixedly connected to the top of the diversion hydraulic cylinder.

[0005] Optionally, a main shut-off mechanism is provided on the water channel. The main shut-off mechanism includes a shut-off gate and two shut-off hydraulic cylinders. The shut-off hydraulic cylinders are vertically arranged on both sides of the water channel. The shut-off gate is located inside the water channel. A fixing plate is provided on the top of the shut-off gate and is fixedly connected to the top of the shut-off hydraulic cylinder.

[0006] Optionally, the cross-sections of the canals, diversion channels, and diversion dikes are all trapezoidal.

[0007] Optionally, the width of the diversion channel is smaller than the width of the main channel.

[0008] The water diversion and drainage device for water conservancy projects of this utility model has the following advantages: (1) The diversion dike divides the waterway into the main waterway and the diversion waterway. Part of the river water continues to flow downstream through the main waterway, while part of the river water is discharged through the diversion waterway and diversion canal. By dredging, the impact of the water flow on the diversion device is reduced, thereby improving the ability of the diversion device to operate stably and improving safety.

[0009] (2) The main interception mechanism can cut off the waterway and store the river water.

[0010] (3) The diversion channel is narrow and the main channel is wide, which can ensure that enough river water can be diverted away regardless of the flow rate. Attached Figure Description

[0013] Figure 3 This is a schematic diagram of the drainage and cutoff machine. Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings.

[0015] like Figures 1-3 As shown, a water diversion and drainage device for a water conservancy project includes a water channel 1. A main interception mechanism 2 is installed on the water channel 1. The main interception mechanism 2 includes an interception gate 3 and two interception hydraulic cylinders 4. The interception hydraulic cylinders 4 are vertically installed on both sides of the water channel 1. The interception gate 3 is located inside the water channel 1, and a fixing plate 5 is installed on the top of the interception gate 3. The fixing plate 5 is fixedly connected to the top of the interception hydraulic cylinders 4. The main interception mechanism 2 can intercept upstream water flow and store river water. A diversion channel 6 is installed on each of the left and right sides of the water channel 1. The two diversion channels 6 are staggered to divert river water to the left and right directions. Two diversion dikes 7 are installed inside the water channel 1, corresponding to the two diversion channels 6. The diversion dikes 7 are located on one side of the diversion channels 6. The side of the diversion dike 7 closest to the diversion channel 6 is called the diversion waterway 8, and the other side of the diversion channel 6 is called the main waterway 9. The width of the diversion waterway 8 is smaller than the width of the main waterway 9. A diversion cutoff mechanism 10 is installed at the inlet of the diversion channel 6. The diversion cutoff mechanism 10 includes a diversion gate 11 and two diversion hydraulic cylinders 12. The diversion hydraulic cylinders 12 are vertically installed on both sides of the diversion channel 6. The diversion gate 11 is installed inside the diversion channel 6. A connecting plate 13 is installed on the top of the diversion gate 11, and the connecting plate 13 is fixedly connected to the top of the diversion hydraulic cylinders 12. The cross-sections of the water channel 1, the diversion channel 6, and the diversion embankment 7 are all trapezoidal to reduce the impact and pressure of the water flow on the device and improve the stability of the device.

[0016] When drainage is not required, both diversion gates 11 remain closed, and the river water flows downstream along the canal 1. When the river flow is large and diversion to one side is necessary, the corresponding diversion hydraulic cylinder 12 extends upward, opening the diversion gate 11. The river water in the diversion channel 8 is then discharged through the diversion canal 6. Due to the diversion dike 7, some river water still flows away through the main channel, preventing significant load pressure on the diversion canal 6. When the river flow is extremely large, both diversion gates 11 are fully opened. Because the diversion channel is narrow and the main channel is wide, the river flow in the diversion canal 6 is limited to its capacity. Excess water still flows downstream through the main channel, preventing damage to the diversion canal 6 and ensuring the long-term stable operation of the drainage system, thus reducing the probability of flood disasters.

[0017] The embodiments described above are merely some embodiments of this utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the protection scope of this utility model.
