Company: 徐州海河水文设备有限公司

Product Description: I. OverviewThe HHL Constant Force Cable Gate Opening Sensor features an internal steel cable that extends and directly connects to the gate being measured. When the gate is raised or lowered, the cable drives a measuring wheel coaxial with an encoder, causing the encoder to rotate synchronously with the gate movement. This converts the gate’s vertical displacement into rotational motion of the encoder shaft, outputting corresponding position data. Its internal mechanical structure mainly consists of a constant force spring, spring wheel, measuring wheel, and wheel shaft. During descent, the gate pulls and rewinds the spring, driving the mechanical components to rotate. During ascent, the force generated by the rewound spring drives the mechanism to rotate and retract the cable. The sensor boasts a rational design, easy installation, strong anti-interference capability, high resolution, large measuring range, long service life, and integrates detection with A/D conversion. It also features signal tracking and memory retention after power loss. It is suitable for long-term displacement detection of measured components while ensuring stable and reliable performance. Ideal for measuring and controlling the lifting height of various gates (including flat gates, radial gates, miter gates, gantry cranes, and bridge cranes), it is an excellent sensor for displacement measurement and control in rivers, lakes, reservoirs, locks, hydropower stations, hydrological stations, water treatment plants, and the petrochemical industry.II.

Product Description: An arc gate is a type of gate that opens and closes by rotating around a support hinge, widely used in various hydraulic structures. The following are its key points:Structural CompositionMainly consists of the gate leaf, supporting arms, support hinge, and sealing device. The gate leaf features a curved panel and beam grid structure (main cross-beam or main longitudinal-beam type). Supporting arms are divided into straight arms and inclined arms, suitable for openings with larger width-to-height ratios and wide open-top scenarios, respectively.Classification MethodsBy water depth: Open-top (water level does not exceed the gate top) and submerged (water level above the gate top);By arm type: Straight arms (suitable for openings with smaller width-to-height ratios) and inclined arms (often used in broad water areas);By hinge type: Cylindrical hinges, conical hinges, spherical hinges, etc., with cylindrical hinges being the most widely used due to their simple structure.AdvantagesSuperior hydraulic conditions: Gate slot-free design reduces water flow resistance, making it suitable for flood discharge needs;Low operating force: Opening and closing are achieved by rotating around the support hinge, requiring minimal operational force;Lightweight structure: Compared to traditional gates, it has less weight and fewer embedded parts, facilitating easy installation. more>

Product Description: The flap gate is a hydraulic facility that achieves automatic water level regulation through the balance of hydraulic force and self-weight. It is primarily used in reservoirs, rivers, and other locations to block or discharge water flow. Its core principle involves lever balance and a rotational mechanism, where the gate’s tilt angle is controlled by changes in the moment of hydrodynamic pressure and gate weight. The structure includes components such as the faceplate, legs, and piers, enabling automatic opening and closing to maintain a set water level range. Core PrincipleThe flap gate utilizes the interaction between water pressure and gravity. When the upstream water level rises, the moment of hydrodynamic pressure on the pivot exceeds that of the gate weight and damping, causing the gate to gradually open around the horizontal axis to release flow. As the water level drops, it automatically closes to retain water. For example, the roller-linkage type gate reduces vibration through a dual-pivot structure and, combined with a trapezoidal practical weir, improves the discharge coefficient for more precise regulation. more>

Product Description: A flap gate is a hydraulic facility that utilizes the balance between hydraulic force and self-weight to achieve automatic water level regulation, primarily used in reservoirs, rivers, and other locations to block or discharge water flow. Its core principle involves lever balance and a rotational mechanism, where the gate's tilt angle is controlled by changes in the moment of water flow pressure and gate weight. The structure includes components such as panels, legs, and piers. Classification and ApplicationFlap gates mainly fall into two categories: Hydraulically Automated Flap Gates and Hydraulic Flap Gates:Hydraulically Automated Flap Gates: Regulate water levels through the mutual balance of hydraulic force and gate weight. They are suitable for small to medium-sized hydraulic engineering projects, featuring simple structures and low costs, and are widely used in flood control, irrigation, and other fields. Hydraulic Flap Gates: Employ a hydraulic system to control opening and closing, allowing manual adjustment of water levels. They are suitable for scenarios requiring precise water level control (such as urban landscapes, hydropower stations, etc.), offering faster operation speeds and superior aging resistance. Technical FeaturesSteel Dam (Bottom Axle-Driven Flap Gate): Uses hydraulic drive technology, supporting stepless water regulation from 0 to 90 degrees. It is suitable for river channels 10-100 meters wide and operates faster than traditional rubber dams. Slider-Type Flap Gate: Optimized with a slider structure to address vibration issues found in early roller-link gates, ensuring more stable flow control. While ensuring the safe operation of hydraulic facilities, flap gates also feature eco-friendly characteristics and can be applied in river management, urban flood control, and other scenarios. more>
