Description

Technical Field

[0001] This utility model belongs to the technical field of water conservancy and hydropower, and more specifically, it relates to a water intake structure that maintains a constant water level at the inlet of a canal system. Background Technology

[0002] Farmland, also known as arable land, refers to land that can be used to grow crops. Paddy fields are arable land used for growing aquatic crops such as rice and lotus, including arable land where aquatic and drought-tolerant crops are rotated. Irrigated land is arable land with guaranteed water sources and irrigation facilities, which can be irrigated normally in normal years, and is used to grow drought-tolerant crops (including vegetables), including non-factory greenhouse land for growing vegetables. Dry land is arable land without irrigation facilities, which mainly relies on natural rainfall to grow drought-tolerant crops, including arable land without irrigation facilities that relies solely on flood diversion for irrigation. In farmland water conservancy projects, canal intakes usually draw water from natural rivers to meet the needs of agricultural irrigation.

[0003] Based on the above, since the water level of natural rivers is affected by factors such as seasonal rainfall, dry season and wet season, its water level fluctuates greatly, which directly affects the water intake stability of the channel inlet. Therefore, a water intake structure that can automatically adapt to the water level changes of natural rivers and keep the water level of the channel inlet basically constant without being affected by the rise and fall of natural rivers, is designed to improve the water intake stability and the stability of the canal system's watershed area, reduce human intervention, and lower operating costs. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a water intake structure that maintains a constant water level at the canal inlet. This addresses the issue that the water level in natural rivers fluctuates significantly due to factors such as seasonal rainfall, dry seasons, and wet seasons, directly affecting the stability of water intake at the canal inlet. Therefore, this invention designs a water intake structure that can automatically adapt to changes in the natural river water level, ensuring that the water level at the canal inlet remains essentially constant regardless of the natural river's rise and fall. This improves water intake stability and the stability of the canal's catchment area, reduces human intervention, and lowers operating costs.

[0009] Furthermore, the mounting side seat is also provided with a guide support and a debris barrier; the guide support is located on the side seat of the mounting side seat, and the debris barrier is located on the side of the guide support.

[0010] Furthermore, the bottom of the adjusting bracket is also provided with an inspection door and a guide block; the inspection door is located at the bottom of the adjusting bracket, and the guide blocks are located on both sides of the inspection door.

[0011] Furthermore, the inner side of the adjustment side channel is also provided with a closed support and a guide inner channel; the closed support is located inside the adjustment side channel, and the guide inner channel is located at the bottom of the closed support.

[0013] The water intake structure provided by this utility model for maintaining a constant water level at the inlet of a canal system has the following beneficial effects:

[0014] This utility model achieves the following optimization effects by setting up a river channel, a bearing support, an adjustment side channel, and a control side channel:

[0015] Intelligent dynamic water level regulation: This innovative system combines a debris-blocking screen with an adaptive water level control system. During the dry season, the system uses a linkage mechanism between a float and control gates to automatically increase the opening degree of the gates as the water level drops, promptly replenishing the channel water. During the wet season, as the river water level rises, the float drives the control gates to close precisely, effectively preventing excessive water inflow. This process requires no manual intervention, and the dynamic balancing mechanism ensures that the water level remains stable at the optimal state, greatly improving the automation level of water conservancy facilities and the efficiency of water resource utilization.

[0016] Highly efficient pollution interception and coordinated operation: While the water level is intelligently regulated, the pollution interception screen continues to play its role, effectively intercepting floating objects such as duckweed, tree trunks and roots, preventing debris from clogging the channel or downstream equipment. Through the coordinated operation of water level and pollution interception functions, the system not only ensures the smooth flow of water in the channel, but also reduces the workload of subsequent cleaning and maintenance, and extends the service life of water conservancy facilities.

[0017] Convenient and safe maintenance design: The unique maintenance structure design greatly improves the convenience and safety of equipment maintenance. When maintenance is required inside the regulating channel, the operator only needs to drive the toothed chain to rotate by adjusting the rocker arm to achieve the coordinated transmission between the threaded support and the threaded cylinder. The precise control of the adjusting bracket drives the maintenance door to move into the positioning bottom frame, quickly cutting off the water flow and forming a safe maintenance space. With the ladder design, maintenance personnel can easily enter the regulating channel without complicated drainage or flow interruption operations, significantly reducing maintenance costs and safety risks, and ensuring the long-term stable operation of water conservancy facilities.

[0038] The specific usage and function of this embodiment: In use, the debris screen 1082 is used to remove floating debris such as duckweed and tree trunks / roots from the river channel 1. When the river channel 1 is in the dry season, the water level in the river channel 1 gradually decreases. As the water level in the river channel 1 decreases, the amount of water entering the channel 401 will naturally decrease. At this time, the water level at the float box 308 will drop due to the decrease in the amount of water coming in, which will cause the float box 308 to drop, breaking the balance previously formed with the control gate leaf 307. Once a certain critical counterweight 309 is exceeded, it will also participate in exacerbating this imbalance. At this time, the drop of the float box 308 will also drive the control gate leaf 307 to open upward. The opening degree increases, and the amount of water coming in will increase due to the increase in the opening degree of the control gate leaf 307. The water level at the float box 308 will rise until it reaches the required level. The water level in the channel 1 gradually rises during the high-water season, leading to a higher dynamic equilibrium state caused by the increased opening degree. As the water level in the channel 1 rises, the amount of water entering the channel 401 naturally increases. At this time, the water level at the pontoon 308 will rise due to the increased water volume, causing the pontoon 308 to rise and breaking the previous balance with the control gate leaf 307. Once a certain critical counterweight 309 is exceeded, it will also participate and exacerbate this imbalance. At this time, the rise of the pontoon 308 will also drive the control gate leaf 307 to close downward, reducing the opening degree. The water volume will decrease due to the reduced opening degree of the control gate leaf 307, and the water level at the pontoon 308 will drop until it is maintained at a lower dynamic equilibrium state caused by the reduced opening degree.
