Description

Technical Field

[0001] This utility model relates to the field of irrigation auxiliary equipment technology, and in particular to the structure of a water level regulating gate for irrigation canals. Background Technology

[0002] As a core control component of farmland water conservancy systems, irrigation canal water level regulating gates play a crucial role in ensuring efficient agricultural water use. By precisely regulating canal water levels, they can achieve on-demand irrigation based on the water requirements of different crops, avoiding water waste and insufficient irrigation, and significantly improving farmland yield and quality. On the other hand, they can effectively balance water resource allocation in different regions, ensuring stable water supply to all nodes of the irrigation network and optimizing the operational efficiency of the agricultural irrigation network. In addition, in response to rainstorms, droughts, and extreme weather, regulating gates can respond quickly, controlling water levels to assist in flood control and drainage or water storage and supply, enhancing the disaster resistance of agricultural production. Their performance directly affects agricultural production efficiency, sustainable water resource utilization, and the stable operation of farmland water conservancy systems, making them an indispensable infrastructure for promoting high-quality development of modern agriculture.

[0003] Traditional gate valves are mostly designed with fixed dimensions, making it difficult to match gate openings of different widths and diverse canal cross-sections. To solve this problem, society currently relies mainly on frequent replacement or customization of gate valves. New projects require gate valves to be customized according to the canal dimensions. From design drawings and mold development to finished product processing, the process is lengthy. Existing systems are affected by water flow erosion and siltation. When the canal cross-section dimensions change, gate valves must also be replaced immediately. However, this still results in extended construction cycles and significantly increased costs. Frequent replacements not only increase the burden on maintenance personnel but also bring high economic costs and serious waste of resources, making it difficult to meet the needs of modern agricultural development.

The design of these bolts 21 allows the long plate 20 to be fixed on the gate frame 207, ensuring the reliability and durability of the entire device.

[0039] Working principle: By moving sliding blocks 1 (4) and 2 (10) up and down, they can slide on the long shaft 6. By moving sliding block 1 (4) downward, rotating plate 1 (7) rotates with connecting shaft 1 (5). By moving sliding block 2 (10) upward, rotating plate 2 (8) rotates with connecting shaft 2 (9). Since rotating plate 1 (7) and rotating plate 2 (8) are connected by connecting shaft 3 (15), connecting shaft 3 (15) drives connecting block 1 (14) to move. Connecting block 1 (14) drives auxiliary plate 3 to move, thus realizing the free adjustment according to the width of the gate and realizing the connection between the gate and the gate.

[0040] By starting motor 202, its output end drives the rotating shaft 203 to rotate, causing bevel gear 204 to rotate along with the rotating shaft 203. The rotation of bevel gear 204 causes bevel gear 205 to rotate along with bevel gear 204, thereby driving the threaded rod 206 to rotate. The rotation of the threaded rod 206 causes gate 209 to move upward. When gate 209 moves to the top of the inner wall of gate 208, it will take gate 208 with it and continue to move upward, thus allowing the water level to be adjusted as needed.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
