Description

Technical Field

[0001] This utility model relates to the field of spillway technology, and in particular to a spillway control section structure. Background Technology

[0002] Spillways typically consist of an intake channel, a control section, a spillway section, an energy dissipation section, and a tailrace channel. The control section controls the spillway's discharge capacity. Currently, most spillway control sections are equipped with working gates to control the water flow velocity. However, during flood discharge, the water often contains debris such as garbage, weeds, and silt. When silt accumulates in the dam body for a long time, some of it will settle on the bottom surface of the dam. When the gates are opened to release water, the water flow impacts this silt, and the silt carried away by the water flow may fall into the gate slot below the working gate body and accumulate again. Existing working gates are not convenient for cleaning the silt at the working gate, and the large amount of accumulated sludge affects the normal closing of the working gates. In addition, the garbage carried by the water flow will be directly washed downstream, causing pollution. Utility Model Content

[0021] Example 1 Please refer to the attached document. Figure 1-4 This application provides a spillway control section structure, including a control section body. The side of the control section body is connected to an intake channel 1. The control section body includes a gate pier 2, a working gate 3, a working bridge 4, and a hoist 5. The gate pier 2 is provided with a plurality of working gates 3. The bottom of the working gate 3 is provided with a sand-blocking sill 6. The sand-blocking sill 6 is provided with a collection trough 7 on the side facing the water flow direction. The bottom of the collection trough 7 is provided with a sand-draining pipe 8. The outlet of the sand-draining pipe 8 is connected to a sediment pool 9. A sand-draining pump 10 is installed on the sand-draining pipe 8. The working bridge 4 is provided above the gate pier 2. The hoist 5 corresponding to the working gate 3 is installed on the working bridge 4. The hoist 5 is fixedly connected to the working gate 3.

[0022] During operation, the intake channel 1 directs the floodwater to the control section of the spillway. The control section consists of gate piers 2, working gates 3, working bridges 4, and hoists 5. Multiple working gates 3 are installed between the gate piers 2 to prevent complete interruption or loss of control of the flow due to the failure of a single gate, thus improving the reliability of the spillway operation. Simultaneously, the number and opening degree of the working gates 3 can be dynamically adjusted based on real-time water level and flow data to ensure that the reservoir water level is always controlled within a safe range, improving the practicality of the spillway. The opening and closing of the working gates 3 is controlled by the hoist 5 on the working bridge 4. Preferably, the hoist 5 is... The winch-type gate hoist intercepts silt and other impurities from the water inlet channel 1 by setting a sand-blocking sill 6 at the bottom of the working gate 3. After interception, the silt settles and accumulates in the collection tank 7 at the bottom. The sand-draining pipe 8 at the bottom of the collection tank 7 pumps the silt from the collection tank 7 to the sand-draining pool 9 on the working bridge 4 through the sand-draining pump 10. This prevents silt and other impurities from falling into the gate slot of the working gate 3 during flood discharge, ensuring the normal opening and closing of the working gate 3. At the same time, the sand-draining pipe 8 pumps the intercepted garbage to the sand-draining pool 9, preventing the garbage from flowing downstream with the water flow and causing pollution, thus protecting the downstream environment.

[0023] Specifically, the control section body is connected to the flood discharge channel 11, and the flood discharge channel 11 is provided with a flow-lifting nose sill 12 at its tail. The floodwater discharged by the control section body flows into the flood discharge channel 11, and the floodwater is introduced downstream through the flood discharge channel 11. The flow-lifting nose sill 12 at the tail of the flood discharge channel 11 causes the water flow to be lifted downstream and diffused, mixing in a large amount of air to dissipate some energy. Then it falls into the river channel far from the nose sill, where it dissipates energy in the water cushion formed by the scour pit and a certain tailwater depth, protecting the downstream structure and riverbank.

[0024] Specifically, a maintenance gate 13 is provided on the side of the working gate 3 facing the intake channel 1, and the maintenance gate 13 is fixedly connected to the mobile hoist 14. By setting a maintenance gate 13 in front of the working gate 3, when maintenance of the working gate 3 is required, the maintenance gate 13 is lowered to separate the working gate 3 from the intake channel 1, and the working gate 3 is opened to release the water between the two gates, making it convenient for maintenance personnel to go to the dam to maintain the working gate 3. After the maintenance is completed, the maintenance gate 13 is opened and the working gate 3 is closed to restore the operation of the spillway.

[0025] Specifically, the collection trough 7 is a rectangular trough with a gradually sloping bottom that slopes down from both ends to the middle. The sand-draining pipe 8 is located in the middle of the bottom of the collection trough 7. The rectangular design of the collection trough 7, with its sloping bottom that slopes down from both ends to the middle, allows sediment to continuously accumulate in the middle of the trough, facilitating cleaning. The sand-draining pipe 8, located in the middle of the trough, maximizes sand discharge and improves cleaning efficiency.

[0026] Specifically, a hoisting machine room 15 is installed on the working bridge 4, and the hoisting machine 5 is installed inside the hoisting machine room 15. By installing the hoisting machine 5 inside the hoisting machine room 15, the metal shell of the hoisting machine 5 is prevented from being oxidized and corroded by rainwater, water vapor, ultraviolet rays, high temperature or low temperature alternation, which would lead to a decrease in structural strength and improve the service life of the hoisting machine 5.

[0027] Specifically, the side wall of the sedimentation tank 9 is provided with a drain outlet 16, and a first filter screen 17 is provided at the drain outlet 16. By providing a drain outlet 16 on the side wall of the sedimentation tank 9 and providing a first filter screen 17 at the drain outlet 16, water in the sedimentation tank 9 can be drained, which facilitates subsequent cleaning of sediment in the sedimentation tank 9.

[0028] Specifically, a filter plate 18 is provided on the side of the sediment tank 9 near the drain outlet 16. By setting the filter plate 18 in the sediment tank 9, the sediment tank 9 is divided into two parts, and the sediment and water are separated. The water is discharged through the drain outlet 16, which improves the separation efficiency.

[0029] Example 2 Please refer to the appendix. Figure 1-4 The difference between this embodiment and Embodiment 1 is that the working gate 3 is provided with wooden piles 19 on the sand-retaining embankment 6, and a second filter screen 20 is connected between the wooden piles 19. The wooden piles 19 are installed on the side of the sand-retaining embankment 6 near the gate. When water flows through them, it creates turbulence and circumference, consuming kinetic energy and reducing the overall flow velocity. During flood discharge, the impact force on the working gate 3 is reduced, thus improving the service life of the working gate 3. Simultaneously, the second filter screen 20 between the wooden piles 19 intercepts impurities floating in the water, preventing impurities from flowing downstream and causing pollution, thus protecting the downstream environment.

[0030] Specifically, it also includes an alarm system, which includes a seepage sensor, a water level sensor, an alarm, a wireless communication module, and a controller. The seepage sensor is installed on the gate pier 2, and the wireless communication device and the controller are installed on the working bridge 4. The seepage sensor is connected to the controller through the wireless communication module, and the controller is electrically connected to the alarm. The water level sensor is installed on the working gate 3 and is connected to the controller through wireless communication. The controller is electrically connected to the hoist 5. By setting up an alarm system, the reservoir environment and usage in the control section are monitored in real time. This includes a seepage sensor installed at gate pier 2 to automatically monitor the seepage pressure at gate pier 2 of the spillway. When the seepage pressure is abnormal, the signal is transmitted to the controller via a wireless communication module. The controller then activates the alarm to sound an alarm in time, giving reservoir staff time to carry out maintenance and reinforcement, and preventing small hidden dangers from developing into major accidents. Additionally, a water level sensor installed on the working gate 3 monitors the water level near the control section of the spillway in real time. When the water level sensor detects that the water level exceeds the flood level, the signal is transmitted to the controller via a wireless communication module. The controller then controls the hoist 5 to select different gate openings to release water based on the water level, ensuring the safe operation of the spillway.
