Description

Technical Field

[0001] This utility model relates to the field of farmland irrigation equipment technology, and in particular to a flat gate with an integrally molded structure. Background Technology

[0002] With the continuous advancement of agricultural modernization, farmland irrigation and drainage management has gradually become a key bottleneck restricting the improvement of agricultural management level and water use efficiency. Against this backdrop, automated flat-panel gates, with their significant advantages such as unmanned operation, high real-time performance, and precise control, are widely used in farmland channels at all levels and irrigation and drainage outlets, becoming important equipment for improving farmland irrigation and drainage management efficiency and promoting the refined development of agriculture. Currently, mainstream gate frames suffer from the following problems: 1. High structural dispersion: Mainstream gate frames are formed by cutting straight sections of aluminum profiles and then splicing them with bolts / angle brackets, resulting in a large number of components, cumbersome installation procedures, and overall rigidity dependent on the strength of the connecting parts. Long-term use is prone to structural loosening due to corrosion or vibration, affecting sealing performance and service life; 2. Low functional integration: The guide rail system (such as pulleys and sealing strip mounting grooves) requires secondary processing or additional components. The gaps between multiple components can easily lead to problems such as gate operation jamming and poor sealing, and the labor costs required for assembly are high. Summary of the Invention

The upper end of the screw is connected to the output end of the actuator and extends downward through the horizontal section of the gate frame. The gate plate is installed inside the gate frame. The gate plate has a strip-shaped notch in the middle with a width greater than the diameter of the screw. The screw sleeve consists of two symmetrical shells and is symmetrically fixed on both sides of the strip-shaped notch of the gate plate. The nut is fixed to the top of the screw sleeve and threaded to the screw.

[0005] Furthermore, the cross-section of the U-shaped section of the gate frame includes one vertical section and two parallel horizontal sections, forming a "π" shaped structure. Pulley guide rail, baffle guide rail and sealing strip guide rail are respectively provided in the two parallel horizontal sections.
