Description

Technical Field

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

[0002] In conventional water conservancy and hydropower projects, water diversion structures guide water from upstream of a reservoir or dam to the turbine room. For example, after a dam is built on a river with a certain head difference to form a reservoir, water is transported to the turbine in the powerhouse according to the designed flow rate and velocity through water diversion tunnels, water diversion pipelines, and other water diversion structures, which drive the turbine to rotate and in turn drive the generator to generate electricity.

[0003] Existing technologies partially utilize rope pulley systems as a manual operation method. Pulleys are installed on the top or side of the gate, with one end of a rope connected to the gate and the other end connected to the operating platform via the pulleys. The operator pulls the rope from the platform, changing the direction of the force through the pulleys, thus moving the gate up and down. However, this method requires high rope strength and maintenance.

[0004] However, in practical use, if the gates cannot be opened and closed, the water diversion cannot be effectively controlled. During flood season, the inability to close the gates in time leads to excessive water flowing into the diversion channel, causing the water volume in the channel to exceed the design standard, resulting in disasters such as channel overflow and levee breaches. For example, when a river experiences a flood peak, if the diversion gates cannot be closed to divert the floodwater into a reservoir for regulation, a large amount of floodwater will directly impact downstream areas, causing flood damage to farmland and towns. Therefore, to address the above-mentioned problems, a water diversion structure for water conservancy and hydropower projects is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1 to 3 One embodiment of this utility model is a water diversion structure for water conservancy and hydropower projects, including a water channel 1. The water channel 1 is one of the main water transport channels, and its construction materials are usually concrete, bricks, or prefabricated U-shaped channels. Concrete canal 1 has good integrity and durability, and can withstand large water flow impact and soil pressure. Its internal surface is generally smoothed and polished to reduce water flow resistance, improve water conveyance efficiency, and reduce leakage. Canal 2 is fixedly connected to the front of canal 1. Canal 2 works in conjunction with canal 1 to realize functions such as water diversion, merging, or turning. The construction materials and structural form of canal 2 are similar to those of canal 1. Its size and shape are determined according to specific water diversion needs. For example, when it is necessary to divert part of the water flow from canal 1 to other areas for irrigation or power generation, the flow rate and size of canal 2 will be designed according to the water demand of the target area. Its width, depth, slope and other parameters will be adjusted accordingly to ensure that the water flow can be distributed and transported according to the predetermined plan.

[0034] A mounting plate 3 is fixedly connected to the top of water channel 2. An opening and closing mechanism is fixedly connected to the top of the mounting plate 3. This mechanism controls the flow of water between water channel 1 and water channel 2, enabling precise water flow regulation. A rotating mechanism is fixedly connected to the left side of water channel 1. This mechanism stirs or guides the water flow within water channel 1, preventing debris accumulation and obstructed flow. The rotating mechanism includes a fixed frame 12, which serves as the mounting base for motor 2 13 and rotating rod 14. Its material is typically metal, such as carbon steel or stainless steel. The carbon steel fixed frame 12 has high strength and rigidity, enabling it to stably support the weight of motor 2 13 and rotating rod 14 and maintain structural stability under water flow impact. Motor 2 13 is fixedly connected to the outside of the fixed frame 12, serving as the power source for the rotating mechanism. The selection of its type requires comprehensive consideration of various factors, such as the scale of the water conservancy project, the required torque and speed of the rotating mechanism, the operating environment, and cost. A rotating rod 14 is fixedly connected to the drive end of motor 2 13. The rotating rod 14, as a key component transmitting motor power and driving the actuating plates 15 to rotate, is generally made of high-strength metal materials, such as alloy steel or stainless steel. The alloy steel rotating rod 14 has high strength and toughness, capable of withstanding the torque output by motor 2 13, as well as the impact and bending forces from the water flow during rotation, ensuring stability and reliability during rotation. Multiple actuating plates 15 are fixedly connected to the outside of the rotating rod 14. As components directly acting on the water flow, the design and installation of the actuating plates 15 have a significant impact on the effectiveness of the rotating mechanism. The actuating plates 15 are generally made of corrosion-resistant, high-strength metal materials or engineering plastics, such as stainless steel, aluminum alloy, or fiberglass. Stainless steel actuating plates 15 have good corrosion resistance and high strength, allowing for long-term use in water flow without easy damage.

[0035] The aluminum alloy actuating plate 15 is lightweight and has high strength. The fixing frame 12 is externally fixed to the front and rear sides of the water channel 1. A collection box 16 is fixedly connected to the right side of the water channel 1. The collection box 16 plays an important role in collecting debris in the water flow in the water diversion structure of the water conservancy and hydropower project. It helps to keep the water flow in the water channel clean, prevents debris from entering the subsequent water conservancy facilities, and reduces equipment damage and maintenance costs. A pushing component is slidably connected inside the collection box 16. The pushing component includes a handle 21. The handle 21 is generally designed to be cylindrical or elliptical, and its diameter is determined according to the size of the human hand. A sliding plate 22 is fixedly connected inside the handle 21. The sliding plate 22 acts as... The main force-bearing components of the push assembly are generally made of high-strength metal materials, such as carbon steel. The carbon steel sliding plate 22 has high strength and rigidity, and can withstand the thrust transmitted from the push plate 25 and the resistance of debris, ensuring that the push assembly can work stably during the debris cleaning process. The four front corners of the sliding plate 22 are fixedly connected with telescopic rods 23. The telescopic rods 23 serve to connect the sliding plate 22 and the push plate 25 in the push assembly, and can also adapt to the position changes of the push plate 25 during the debris cleaning process. The telescopic rods 23 are fitted with springs 24 on the outside, and the other end of the telescopic rods 23 is fixedly connected to the push plate 25. The handle 21 is slidably connected to the inside of the collection box 16.

[0036] The opening and closing mechanism includes a motor 4, which serves as the power source. The type of motor 4 can be selected according to actual needs, such as an AC asynchronous motor 4. The AC asynchronous motor 4 has advantages such as simple structure, reliable operation, and low cost, and is widely used in some water conservancy projects where the control precision requirements are not particularly high. A rotating plate 5 is fixedly connected to the drive end of the motor 4. The rotating plate 5, as a key component connecting the motor 4 and the connecting plate 6, is generally made of metal, such as carbon steel. The carbon steel rotating plate 5 has high strength and rigidity, can stably transmit the power of the motor 4 and drive the connecting plate 6, and is relatively inexpensive. Connecting plates 6 are rotatably connected to the left and right sides of the rotating plate 5. The connecting plates 6, as intermediate components connecting the rotating plate 5 and the fixed rod 7, are generally made of metal, such as carbon steel. The carbon steel connecting plates 6 have relatively high strength and rigidity, can stably transmit the power of the motor 4 and drive the connecting plate 6, and are relatively inexpensive. With high strength and rigidity, it can stably transmit force and motion. The other end of the connecting plate 6 is fixedly connected to a fixing rod 7. The fixing rod 7 is a component connecting the limiting ring 8 and the gate 9. Its material is generally metal, such as carbon steel. The carbon steel fixing rod 7 has high strength and rigidity, and can stably bear the weight of the limiting ring 8 and the gate 9 and maintain structural stability under the impact of water flow. The fixing rod 7 is externally fixedly connected to the limiting ring 8. The stainless steel limiting ring 8 is known for its excellent corrosion resistance and is particularly suitable for use in humid environments with corrosive media. It can effectively prevent rust and corrosion and ensure that the lifting range of the gate 9 can be accurately limited during long-term use.

[0037] A gate 9 is fixedly connected to the bottom of the fixed rod 7. As a key component that directly controls the flow of water, the gate 9 is generally made of metal, such as carbon steel, stainless steel, or cast iron. Carbon steel gates 9 have high strength and rigidity, can withstand large water flow impact and pressure, and are relatively inexpensive. Stainless steel gates 9 are known for their excellent corrosion resistance, and are particularly suitable for use in water flows containing corrosive media. They can effectively prevent rust and corrosion, ensuring the stability and reliability of the gate 9 during long-term use. The motor 4 is externally fixedly connected to the top of the mounting plate 3.

[0038] Reference Figures 3 to 4 Sealing gaskets 10 are fixedly connected to both the left and right sides of the outer side of water channel 2. The sealing gaskets 10 are generally made of rubber materials with good elasticity and water resistance, such as neoprene rubber. Neoprene rubber sealing gaskets 10 have high strength and wear resistance, can effectively resist the scouring and wear of water flow, and can maintain good elasticity and sealing performance under normal water temperature conditions. A connecting rod 11 is fixedly connected to the top of water channel 2. The connecting rod 11 is an important component for connecting other parts or auxiliary structures. Its material is usually metal, such as carbon steel. Carbon steel connecting rod 11 has high strength and good processing performance, can meet general structural connection requirements, and has a relatively low cost. Stainless steel connecting rod 11 is favored for its excellent corrosion resistance. It is particularly suitable for use in humid environments with corrosive media, which can effectively prevent rust and corrosion and ensure long-term stability.

[0039] The gate 9 is externally slidably connected to the inside of the sealing gasket 10. The inside of the collection box 16 is provided with sliding grooves 17 on both the left and right sides. The sliding grooves 17 serve as the tracks for the handle 21 and the sliding plate 22 to slide, and their shape is usually a rectangular groove. The dimensions of the slide groove 17 are precisely designed according to the dimensions of slider 19 and slider 20. The width of the slide groove 17 is slightly larger than the width of slider 19 and slider 20. Slider 19 is fixedly connected to both the left and right sides of the handle 21. Slider 19 is a key component for the sliding connection between the handle 21 and the slide groove 17. Its material is generally metal, such as carbon steel. Carbon steel slider 19 has high strength and rigidity, and can slide stably in the slide groove 17 and withstand a certain amount of external force. Stainless steel slider 19 is suitable for humid environments with corrosive media due to its excellent corrosion resistance. It can effectively prevent rust and corrosion and ensure long-term performance. The outside of slider 19 is slidably connected to the inside of the slide groove 17. Slider 20 is fixedly connected to both the left and right sides of the outside of the sliding plate 22. Slider 20 is slidably connected to the inside of the slide groove 17. A collection net 18 is fixedly connected to the front of the collection box 16.

[0040] The collecting net 18, as a crucial component for intercepting debris in the water flow, is typically made of corrosion-resistant, high-strength metal wire or synthetic fiber materials. The metal wire collecting net 18, such as one woven from stainless steel wire, possesses high strength and corrosion resistance, maintaining structural integrity even under long-term water flow and effectively intercepting various debris. The exterior of the push plate 25 contacts the interior of the collecting net 18. One end of the spring 24 is fixedly connected to the front exterior of the sliding plate 22. As an elastic element in the pushing assembly, the spring 24 plays a buffering and assisting role in the overall structure. The spring 24 is generally made of high-quality spring steel, undergoing a special heat treatment process to achieve excellent elastic properties and fatigue life. The other end of the spring 24 is fixedly connected to the rear exterior of the push plate 25.

[0041] Working principle: When opening and closing the gate 9, the motor 4 is started. Under the action of the motor 4, the rotating plate 5 is driven to rotate. Under the action of the rotating plate 5, the rotating plate 5 drives the connecting plates 6 on the left and right sides to rotate. The connecting plates 6 can drive the gate 9 to slide through the fixed rod 7, thereby realizing the opening and closing of the gate 9.

[0042] When collecting debris from the water flow, motor 13 is started. Under the action of motor 13, the rotating rod 14 drives the actuating plate 15 to rotate, which in turn causes the actuating plate 15 to transport the debris into the collection box 16. Then, by sliding the handle 21, the debris inside the collection box 16 is transported into the collection net 18. Because of the spring 24, the spring 24 can drive the push plate 25 to push the debris into the collection net 18.
