Description

Technical Field

[0001] This utility model relates to the technical field of water depth measurement devices, and more specifically, to a fixed device for measuring dynamic draft. Background Technology

[0002] Dynamic draft refers to the change in draft caused by a ship's motion while sailing. In water depth measurement, we usually measure the transducer draft accurately when the ship is stationary (i.e., "static draft"). However, dynamic draft during motion is often ignored or only slightly corrected. Compared to a stationary state, a ship sinks a certain depth while sailing, and the draft varies depending on different speeds, ship types, and hydrological conditions. Static draft cannot accurately reflect the true draft during the measurement process, thus affecting the accuracy of water depth data.

[0003] Conventional dynamic draft measurement methods often involve mounting the GNSS RTK on the side of the ship. The mounting location depends on the ship's structure and is not fixed, which affects the measurement efficiency. When the measuring ship moves, its attitude changes, and the attitude of the GNSS RTK changes accordingly, resulting in quality defects. Summary of the Invention

According to the above scheme, the depth measuring rod locking fastener has a bolt hole in the middle, and the depth measuring rod locking fastener is connected and fixed to the square plate by the depth measuring rod fastening screw.

[0006] According to the above scheme, the square plate is a serrated square plate. According to the above scheme, the sounding rod locking fastener is square in shape with a "C" shaped opening inside. According to the above scheme, the sounding rod locking fastener is connected to the left topographic rod locking fastener via a connecting rod. According to the above scheme, the left terrain pole locking fastener and the right terrain pole locking fastener are connected by fixing screws, and the fixing screws include two screws respectively set at the upper and lower ends of the left terrain pole locking fastener and the right terrain pole locking fastener.
