Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering, and more specifically, to a power generation device for water conservancy engineering. Background Technology

[0002] In today's energy sector, hydropower is receiving increasing attention as a clean and renewable energy production method. Water conservancy projects aim to comprehensively develop and utilize water resources and eliminate water hazards, covering multiple fields such as flood control, farmland irrigation, hydropower generation, waterways and ports, water supply and drainage, environmental water conservancy, and coastal reclamation. Among them, hydropower generation is the key link in converting the potential energy of water into electrical energy. However, in existing water conservancy projects, when the turbine blades of the power generation device rotate counterclockwise, they drive the drive shaft to rotate synchronously. But when the turbine blades rotate clockwise, they do not drive the drive shaft to rotate, thus achieving the purpose of unidirectional rotation. This wastes the power of the turbine blades rotating clockwise, thereby reducing the power generation efficiency.

[0003] To address the aforementioned issues, existing power generation devices for hydraulic engineering utilize turbine blades that rotate counterclockwise to drive the drive shaft synchronously, but not clockwise, achieving unidirectional rotation. This wastes the power generated during clockwise rotation, thus reducing power generation efficiency. Extensive research revealed a power generation device for hydraulic engineering with patent publication number CN215521115U. This device, belonging to the field of hydraulic engineering, uses a transmission and driven assembly that works in conjunction to ensure that the power supplied to the power generation device is always clockwise, regardless of whether the turbine blades rotate clockwise or counterclockwise. This avoids problems caused by bidirectional rotation and prevents the waste of power generated during counterclockwise rotation, significantly improving power generation efficiency.

[0004] However, the aforementioned power generation device for water conservancy projects still has some problems. For example, during use, debris in the water flow can easily enter the device, causing malfunctions and affecting its operation. To address these problems, this utility model proposes a power generation device for water conservancy projects. Summary of the Invention

Detailed Implementation

[0023] The following will refer to the appendix in the embodiments of this utility model. Figures 1-6The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0024] Please see Figure 1-6 In this embodiment of the utility model, a power generation device for water conservancy projects includes a fixed block 1, on which a power generation component 8 is provided. Two side plates 2 are fixedly installed on the top of the fixed block 1, and a collection basket 3 is fixedly installed between the two side plates 2. Multiple guide plates 5 are spaced apart along the length of the collection basket 3. A cleaning component 9 is provided between the two side plates 2. The cleaning component 9 includes a first rotating shaft 92, which is rotatably mounted on the two side plates 2. Multiple blades 91 and a first gear 94 are fixedly installed on the first rotating shaft 92 along its circumference. The second rotating shaft 95 is rotatably mounted on the side plate 2. The second rotating shaft 95 and the first rotating shaft 92 are connected by a first chain and sprocket mechanism 93. The third rotating shaft 96 is rotatably mounted on the two side plates 2. Multiple sets of cleaning components are fixedly installed on the third rotating shaft 96 along its circumference. The cleaning components include multiple cleaning rods 98 spaced apart along the length of the third rotating shaft 96. The multiple cleaning rods 98 are offset from multiple guide plates 5. A second gear 97 that meshes with the first gear 94 is sleeved and fixedly mounted on the third rotating shaft 96.

[0025] Specifically, by installing the fixing block 1 at the drop point of the water flow (i.e., the connection between the high-level and low-level water flow), with one end of the fixing block 1 housing the cleaning component 9 facing the high-level water area and the inclined slope 13 located in the low-level water area, after installation, the water flow impacts the blades 91 on the first rotating shaft 92, causing the first rotating shaft 92 to rotate. The first rotating shaft 92 drives the second rotating shaft 95 to rotate via the first chain and sprocket mechanism 93, thereby causing the first gear 94 to rotate. The first gear 94 meshes with the second gear 97, driving the third rotating shaft 96 to rotate. The multiple sets of cleaning components on the third rotating shaft 96 rotate accordingly, causing the multiple cleaning rods 9... 8. Debris flowing through the water on top of the fixed block 1 is hooked up. As the third rotating shaft 96 rotates, due to the misalignment between the cleaning rod 98 and the guide plate 5, the debris hooked up by the cleaning rod 98 is scraped off by the guide plate 5 and falls into the collection basket 3 (the collection basket 3 has multiple drainage holes). The overall structure has a high degree of automation. The cleaning component 9 is driven by the energy of the water flow itself, without the need for an additional power source, saving energy. Multiple cleaning rods 98 work together to effectively clean debris in the water flow, reduce the impact of debris on the water flow and power generation equipment, extend the service life of the equipment, and ensure the stable operation of the power generation device.

[0026] In this embodiment of the utility model, such as Figure 1 , Figure 2 and Figure 6As shown, the cleaning rod 98 includes an integrally formed rod body 981 and a hook 982. Specifically, the integrally formed design of the rod body 981 and the hook 982 enhances the structural strength and cleaning ability of the cleaning rod 98, enabling it to clean various types of debris more effectively and improving the working efficiency of the cleaning assembly 9. Furthermore, the guide plate 5 is inclined toward the collection basket 3, which can improve the collection efficiency of the collection basket 3 for debris, making it easier for debris on the cleaning rod 98 to be discharged into the collection basket 3.

[0027] In this embodiment of the utility model, such as Figure 2 As shown, the diameter of the first gear 94 is smaller than the diameter of the second gear 97.

[0028] In this embodiment of the utility model, such as Figures 1 to 5 As shown, the fixed block 1 has a downward-sloping slope 13 at the end opposite to the blade 91. The power generation component 8 is set on the slope 13. The power generation component 8 includes two fixed plates 81, which are fixedly installed on the slope 13. Two mounting plates 85 are fixedly installed between the two fixed plates 81. An Archimedes screw 84 is rotatably installed between the two mounting plates 85. A generator 82 is fixedly installed on the two fixed plates 81. The drive shaft of the generator 82 is connected to the Archimedes screw 84 through a second chain sprocket mechanism 83. Specifically, the Archimedes screw 84 converts the kinetic energy of the water flow into mechanical energy, which is then converted into electrical energy by the generator 82. The structure is simple and efficient, which can make full use of the energy of the water flow and improve the power generation efficiency of the power generation device. It is suitable for scenarios with different water flow speeds.

[0029] In this embodiment of the utility model, such as Figures 1 to 5 As shown, an arc-shaped groove 4 is embedded in the inclined slope 13 relative to the Archimedes screw 84. The Archimedes screw 84 is rotatably mounted in the arc-shaped groove 4. Specifically, the arc-shaped groove 4 provides rotational support and guidance for the Archimedes screw 84, enabling the Archimedes screw 84 to rotate stably in the groove, ensuring its coaxiality, reducing swaying and offset, improving the stability and reliability of the rotation of the Archimedes screw 84, reducing wear and energy loss caused by swaying, helping to extend the service life of the Archimedes screw 84, and ensuring the stable operation of the power generation device.

[0030] In this embodiment of the utility model, such as Figures 2 to 5As shown, a protective cover 7 is fixedly installed between the two fixed plates 81. The protective cover 7 is configured to protect the connection between the second chain sprocket mechanism 83 and the Archimedes screw rod 84. A cover plate 12 is detachably provided on the protective cover 7. Specifically, the protective cover 7 protects the connection between the second chain sprocket mechanism 83 and the Archimedes screw rod 84, preventing water, debris, etc. from entering the connection and affecting the transmission effect or causing damage to the components. The cover plate 12 is detachable, which facilitates the inspection and maintenance of the internal transmission components. It should be noted that a groove is provided through the cover plate 12 to allow the second chain sprocket mechanism 83 to move.

[0031] In this embodiment of the utility model, such as Figures 1 to 5 As shown, baffles 10 are fixedly installed between the two fixed plates 81 and the two side plates 2. Drainage channels 11 are provided through the baffles 10. Specifically, the baffles 10 are used to guide the water flow, so that the water flows into the arc-shaped channel 4 according to the designed path. The drainage channels 11 allow the water to pass through after the water level increases after being blocked by the baffles 10. Furthermore, a screen 6 is fixedly installed between the two baffles 10. The screen 6 is installed between the two baffles 10 to filter the water flow and intercept smaller impurities in the water flow, preventing these impurities from entering the power generation component 8 and affecting the operation of the device.

[0032] Working principle: By installing the fixing block 1 at the drop in water flow (i.e., the connection between the high-level and low-level water flow), with one end of the fixing block 1 housing the cleaning component 9 facing the high-level water area and the inclined slope 13 located in the low-level water area, after installation, the water flow impacts the blades 91 on the first rotating shaft 92, causing the first rotating shaft 92 to rotate. The first rotating shaft 92 drives the second rotating shaft 95 to rotate through the first chain and sprocket mechanism 93, thereby causing the first gear 94 to rotate. The first gear 94 meshes with the second gear 97, driving... The third rotating shaft 96 rotates, and the multiple sets of cleaning components on the third rotating shaft 96 rotate accordingly, causing multiple cleaning rods 98 to hook up debris in the water flowing over the top of the fixed block 1. As the third rotating shaft 96 rotates, due to the misalignment between the cleaning rods 98 and the guide plate 5, the debris hooked by the cleaning rods 98 is scraped off by the guide plate 5 and falls into the collection basket 3 (the collection basket 3 is provided with multiple drain holes). Subsequently, the water flows along the fixed block 1 to between the two baffles 10, where the screen 6 further filters the water. Small debris in the water flow is removed to ensure the normal operation of the power generation component 8. Subsequently, two inclined baffles 10 guide the water flow to the arc-shaped groove 4, impacting the Archimedes screw 84. Under the impact of the water flow, the Archimedes screw 84 rotates around its own axis. Its rotation is transmitted to the drive shaft of the generator 82 through the second chain sprocket mechanism 83, driving the generator 82 to generate electricity. The water flow in the arc-shaped groove 4 provides a stable water flow impact environment for the Archimedes screw 84, ensuring its continuous rotation. The protective cover 7 protects the connection between the second chain sprocket mechanism 83 and the Archimedes screw 84, preventing debris from entering and damaging the equipment. At the same time, the cover plate 12 facilitates internal inspection and maintenance. The overall structure has a high degree of automation. The cleaning component 9 is driven by the energy of the water flow itself, requiring no additional power source, thus saving energy. Multiple sets of cleaning rods 98 work together to effectively clean debris in the water flow, reduce the impact of debris on the water flow and power generation equipment, extend the service life of the equipment, and ensure the stable operation of the power generation device.
