5 results about "Tidal range" patented technology

This invention discloses a method for estimating long-duration design tidal process lines, comprising: preprocessing and frequency analysis of historical tidal data to obtain the design high tide level, design flood tide range, and design ebb tide range; selecting a typical long-duration tidal process containing the highest tide level, and selecting a "one flood, one ebb" process at a later position as the main tidal type according to the principle of "high tide level - long duration - later high tide level", with the rest being secondary tidal types; using the design high tide level, design flood tide range, and design ebb tide range to perform same-frequency combination design on the main tidal type to obtain the design main tidal type process; using the scaling ratio of the corresponding phase points of the design main tidal type and the measured main tidal type as a benchmark, scaling the secondary tidal types accordingly to obtain the design secondary tidal type processes; and splicing the results to obtain the complete long-duration design tidal process. This invention overcomes the limitation of existing methods that can only deduce "one flood, one ebb" processes and is applicable to the calculation of any long-duration design tidal process.

The application discloses a design water level calculation method and device for an unobserved sea area. The method comprises the following steps: acquiring measured data of a marine station adjacent to a target unobserved sea area, wherein the measured data of the marine station comprises a measured mean tidal range and a measured design water level; constructing a correction formula according to the measured data of the marine station, wherein the correction formula comprises a corresponding relationship between the mean tidal range and the design water level; training a numerical model with a tide level simulation function by using the measured data of the marine station to obtain a calibration model; calculating a simulated mean tidal range by using the calibration model; and obtaining a design water level of the target sea area according to the simulated mean tidal range and the correction formula. The design water level calculation method and device for the unobserved sea area can accurately calculate the design water level of the unobserved sea area, and have high flexibility and applicability, and can adapt to different sea area engineering layout requirements.

This invention relates to the field of testing equipment technology, specifically to a stainless steel corrosion performance testing equipment for a full-zone simulated seawater environment. The equipment includes: a test chamber, which is vertically arranged along the interior of the chamber via multiple partitions, sequentially from top to bottom, comprising an atmospheric test zone, a splash test zone, a tidal range test zone, a full immersion test zone, and a sea mud test zone; and a simulation unit, including a sea breeze simulation component and a wave simulation component respectively connected and installed on the side wall of the test chamber, for providing a simulated seawater environment. By separately setting the atmospheric test zone, splash test zone, tidal range test zone, full immersion test zone, and sea mud test zone inside the test chamber, the equipment can work with the sea breeze simulation component and the wave simulation component to simulate a full-zone seawater environment. This allows for convenient testing of the corrosion resistance of stainless steel pipes in different zones of a simulated real marine environment, improving the accuracy of the test, reducing the manpower and material resources consumed in the test, and reducing the workload of the personnel involved in the test.

This utility model discloses a garbage transfer platform for fishing port operation areas, including a support platform fixed to the quay or wharf and a lifting and conveying device on one side. The lifting and conveying device includes a support tray, a lifting guide structure, and a drive assembly consisting of a lead screw and a servo motor. The drive assembly moves the tray up and down between positions above and below the platform's working surface, and is controlled by a control system to stop at a preset position. The lifting guide structure consists of parallel vertical guide rails and a slider assembly. An anti-fall locking mechanism is provided at the lower end of the lead screw. Adjustable positioning blocks and locking claws are provided on the tray to secure garbage containers. The platform is composed of uprights, main beams, and secondary beams. The panel is detachable, and a perimeter fence is provided. The outer surface is covered with a corrosion-resistant layer or anti-corrosion coating, adapting to the tidal range of fishing ports and enabling efficient and safe garbage transfer.
