Description

Technical Field

[0001] The utility model belongs to the technical field of gates, and in particular relates to a drainage gate for water conservancy facilities with safe and reliable sealing. Background Art

[0002] Irrigation areas usually use rivers and gates or flap gates to draw water from reservoirs or rivers. Gates are a commonly used device and are widely used. Gates are control facilities used to close and open water discharge (release) channels. An important component of hydraulic structures, they can be used to intercept water flow, control water levels, regulate flow, discharge sediment and floating objects, etc. The gate consists of a frame installed on the canal outlet and a gate plate set in the frame through a slide rail to control the water flow state. The surface of existing gates is mostly alloy or steel, with a solid interior, or filled with concrete, etc., which makes the valve very bulky, making the device driving the valve have a large horsepower and high energy consumption. Therefore, it is very important to obtain a safe and reliable drainage gate for water conservancy facilities that overcomes the above defects. Utility Model Content

[0005] A hollow cavity is provided between the first panel and the second panel, and at least one reinforcing rib is provided in the hollow cavity for fixedly connecting the first panel and the second panel.

[0006] Preferably, at least three side walls of the drainage gate frame are provided with slots for accommodating the drainage gate body, and at least three sides of the drainage gate body are provided with protrusions that match the slots. A limiting slot is provided on the side wall of the protrusion, and a limiting strip that matches the slide rail is provided in the slot, and sealing strips are fixed on both sides of the slot located on both sides of the limiting strip. The surface of the sealing strip is provided with a plurality of wedge-shaped grooves, and the sealing surfaces of the protrusions located on both sides of the limiting grooves match the wedge-shaped groove surface of the sealing strip, and the sealing surfaces squeeze the wedge-shaped groove to deform the sealing strip to achieve sealing.

[0007] Through the above technical solution, the movable sealing of the drainage gate body can be achieved.

[0008] There are many methods for controlling the valve. One of them is: a fixing column is fixed inside the drainage gate body, a threaded groove is opened on the inner wall of the fixing column, a threaded channel is opened on the top of the drainage gate frame, a stud is threadedly connected to the threaded channel, the first end of the stud is located in the threaded groove, and the second end passes through the threaded channel and is fixed with a handwheel.
