Description

Technical Field

[0001] The utility model relates to the technical field of demonstration devices, in particular to a demonstration device for the impact of channel leakage. Background Art

[0002] A demonstration device for the impact of canal leakage is typically a model or device used for demonstration and educational purposes. It simulates actual canal leakage under various conditions, helping people understand the causes, processes, and potential consequences of canal leakage. Through such a device, students, engineers, or policymakers can visually visualize the impacts of canal leakage, such as water loss characteristics, water movement characteristics in farmland, and irrigation effects.

[0003] Specifically, during the process of conveying water from the source through channels to farmland, water leakage can occur to varying degrees due to poor channel construction quality, inadequate anti-seepage treatment technology, and years of disrepair. This leakage not only results in ineffective loss of irrigation water resources, but also affects the speed and flow of water entering the fields, thereby affecting the flow of water to the end of the field and the vertical infiltration rate of soil moisture. This will further affect the uniformity of water distribution within the field, thereby affecting the irrigation effect of the entire farmland.

[0004] To help students better understand the complex irrigation process and its potential impacts, a demonstration device demonstrating the effects of channel leakage is crucial. This interactive teaching tool not only allows students to visually observe the impact of water leakage on irrigation uniformity but also teaches them how to manage and control irrigation systems to ensure efficient use of water resources. More importantly, this demonstration device fosters a sense of safety and responsibility, educating them on the equal importance of safety and efficiency in irrigation district management.

[0005] By simulating actual irrigation scenarios, students learn how to identify and resolve potential problems, such as adjusting irrigation strategies to optimize water flow distribution and improve irrigation uniformity. This hands-on experience not only strengthens students' practical skills but also inspires a passion for fulfilling their responsibilities, laying a solid foundation for their future careers in agricultural irrigation. This educational approach allows students to better understand how irrigation systems work and how to apply this knowledge in real-world operations to ensure sustainable agricultural production and the rational use of water resources.

[0006] The existing demonstration device for the impact of channel leakage is not convenient for displaying the movement process of farmland water flow and irrigation effect during use, and it is difficult to collect the leaked water, which affects the user's understanding of the amount of leaked water and reduces the demonstration effect during use of the demonstration device.

[0031] Furthermore, a controller 4 is fixedly installed on the left side of the water tank 1.

[0032] Furthermore, the farmland simulation trough 7 is internally fixedly connected with a plurality of conductive sheets 8 .

[0033] Furthermore, the collecting mechanism 2 includes a collecting hopper 201 , which is located at the bottom of the first U-shaped channel 5 , the second U-shaped channel 6 and the third U-shaped channel 13 . A collecting box 203 in communication with the collecting hopper 201 is fixedly mounted at the bottom.

[0034] Furthermore, a liquid level sensor 202 is fixedly installed on the top of the collection box 203 , a detection end of the liquid level sensor 202 extends to the inner cavity of the collection box 203 , and a drain valve 204 is connected to the bottom of the surface of the collection box 203 .

[0035] Furthermore, the mixing mechanism 3 includes a first rotating rod 301 and a second rotating rod 306, which are rotatably connected to the inner wall of the water tank 1. The rear side of the first rotating rod 301 is fixedly connected to a reduction motor 303, and the reduction motor 303 is fixedly installed on the rear side of the water tank 1.

[0036] Furthermore, the surfaces of the first rotating rod 301 and the second rotating rod 306 are fixedly provided with several stirring impellers 307, the rear end fixed sleeve of the first rotating rod 301 is provided with a driving pulley 302, and the rear end fixed sleeve of the second rotating rod 306 is provided with a driven pulley 305, and the surfaces of the driving pulley 302 and the driven pulley 305 are connected with belts 304 for transmission.

[0037] When demonstrating the impact of channel leakage, water and dye are injected into the water tank 1 in advance, and the mixing mechanism 3 mixes the water and dye evenly to facilitate observation of the flow pattern of the water. The output shaft of the reduction motor 303 drives the first rotating rod 301 to rotate, and the first rotating rod 301 drives the second rotating rod 306 to rotate synchronously through the active pulley 302, the belt 304 and the driven pulley 305. The first rotating rod 301 and the second rotating rod 306 are respectively located on the left and right sides of the inner cavity of the water tank 1, and drive several stirring impellers 307 to stir and mix the water and dye, thereby improving the efficiency of the demonstration.

[0038] The mixed water enters the first U-shaped channel 5, the second U-shaped channel 6 and the third U-shaped channel 13 through the first gate valve 12 and the first flowmeter 11. The water-stop pad 14 seals the joints of the first U-shaped channel 5, the second U-shaped channel 6 and the third U-shaped channel 13. The first gate valve 12 controls the amount of water output. The first flowmeter 11 detects the water flow rate. During the flow of water, leakage is simulated through the drain hole on the second U-shaped channel 6.

[0039] Specifically, when the second U-shaped channel 6 uses modules with all small holes, it simulates a scenario where the channel is relatively intact but still has minor leaks. Using modules with all large holes can simulate the extreme case of severe damage and severe leakage. As for the use of modules with medium holes, they are between small and large holes and simulate leakage in a channel with moderate damage. This simulation helps to more fully understand the leakage characteristics and irrigation effects of channels with different degrees of damage, providing a basis for developing targeted maintenance plans and irrigation programs.

[0040] Furthermore, considering the impact of different anti-seepage materials on channel leakage, the second U-shaped channel 6 can be replaced with one of different permeability characteristics for actual simulation. Generally, earthen channels are highly permeable and have relatively severe leakage, requiring regular maintenance and reinforcement. However, lined channels, due to their use of impermeable or low-permeability materials, can significantly reduce leakage and improve water resource utilization efficiency.

[0041] In summary, by replacing the second U-shaped channel 6 with different apertures and selecting the second U-shaped channel 6 with different permeable materials, the leakage of the U-shaped channel under different conditions can be fully simulated and evaluated, providing strong support for the design, construction and maintenance of the channel.

[0042] Furthermore, when the second U-shaped channel 6 needs to be replaced, the flange at the connection between the first U-shaped channel 5, the second U-shaped channel 6 and the third U-shaped channel 13 is disassembled, and the water-stop pad 14 at the connection is removed to replace the second U-shaped channel 6 with a different material and a different aperture, thereby simulating leakage conditions of various channels and improving the scope and flexibility of use.

[0043] The leaked water enters the collecting hopper 201 and is collected by it. The collected water is stored in the collecting box 203. The liquid level sensor 202 detects the liquid level inside the collecting box 203 to facilitate the user to calculate the volume of the leaked water. When the demonstration is completed, the drain valve 204 is opened to drain the water inside the collecting box 203.

[0044] The water inside the third U-shaped channel 13 enters the farmland simulation tank 7 through the second flow meter 10 and the second gate valve 9. The second flow meter 10 detects the flow of the incoming water, and the second gate valve 9 controls the opening and closing of the incoming water. After the water enters the farmland simulation tank 7, it spreads inside the farmland simulation tank 7, demonstrating the phenomenon of farmland being flooded. When the water contacts several conductive sheets 8, a conductive loop is formed. The conductive signal of the conductive sheet 8 is transmitted to the controller 4 to form water flow movement distribution data.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
