Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, and in particular to a ship draft measurement device. Background Technology

[0002] Ships are the primary means of water transportation. Every ship has its maximum deadweight tonnage, also known as its maximum draft. Draft refers to the depth to which the hull is submerged in water, and it is crucial for navigational safety and ship performance. A ship's speed is affected by its deadweight tonnage, therefore, its draft must be measured when loaded. Traditionally, the draft of a ship is determined primarily by observing the waterline on the hull, but this method is prone to errors due to variations in viewing angle. Summary of the Invention

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] This embodiment provides a ship draft measurement device, such as... Figure 1 and Figure 2 As shown, it includes measuring mechanism 3, such as Figure 3 and Figure 6 As shown, the measuring mechanism 3 includes a measuring tube 301 disposed inside the hull 1, and the bottom of the measuring tube 301 is connected to the outside of the hull 1.

[0029] like Figure 3 As shown, the measuring tube 301 is provided with multiple sliding rods 302, and a slider 303 is sleeved on the sliding rods 302, such as... Figure 3 and Figure 5 As shown, a float plate 304 is fixed between the plurality of sliders 303, such as Figure 6 As shown, the measuring tube 301 is provided with an observation window 305, and the measuring tube 301 or the observation window 305 is provided with a scale 306.

[0030] In this embodiment, as Figure 4 and Figure 6 As shown, it also includes a bracket 2 welded and fixed to the hull 1, the measuring tube 301 is fixed to the bracket 2 (the measuring tube 301 can be clamped and fixed by the bracket 2; or, the measuring tube 301 can be welded and fixed to the bracket 2), two sliding rods 302 are welded and fixed inside the measuring tube 301, the float 304 is fixed together with two sliders 303, and the scale 306 is set on the measuring tube 301.

[0031] This embodiment discloses a ship draft measurement device. By setting a measuring tube 301 inside the hull 1 and communicating with the outside of the hull 1, the device utilizes the principle of communicating vessels (under pressure, seawater will enter the measuring tube 301, making its internal liquid level level with the external sea level) to match the liquid level of the measuring tube 301 with the draft depth. The float 304 drives the sliders 303 on both sides to slide on the sliding rods 302. The float 304 inside the measuring tube 301 is always above the seawater entering the measuring tube 301. The crew can quickly confirm the draft depth through the observation window 305 and the scale 306, which is highly practical. The float 304 inside the measuring tube 301 is slidably connected to multiple sliding rods 302 through the sliders 303 to ensure the stable and reliable movement of the float 304, thereby reducing measurement errors and the possibility of misjudgment.

[0032] In a specific embodiment, such as Figure 1 and Figure 2 As shown, it also includes a connecting pipe 4, one end of which is connected to the bottom of the measuring pipe 301, and the other end of which is connected to the outside of the hull 1.

[0033] In this embodiment, one end of the connecting pipe 4 that connects to the outside of the hull 1 is watertightly welded to the hull 1, and the connecting pipe 4 may be composed of several pipes and elbows.

[0034] In a specific embodiment, a valve 6 is provided on the connecting pipe 4, which can control the opening and closing of the connecting pipe 4.

[0035] In a specific embodiment, such as Figure 1 and Figure 2 As shown, a pressure gauge 5 is installed on the connecting pipe 4. The pressure gauge 5 can be used to detect the pressure of the liquid inside the measuring device 3. The operator can judge the rising speed of the liquid level based on the pressure change. If the rising speed is too fast, the valve 6 can be closed to avoid seawater overflow as much as possible.

[0036] In a specific embodiment, such as Figure 1 As shown, the top of the measuring tube 301 is provided with an air guiding component 7. The air guiding component 7 includes a cover 701, a U-shaped bend 702 and a vent cap 703 that are welded and fixed in sequence. The U-shaped bend 702 has its opening facing downwards, and the cover 701 has a through hole that connects to the U-shaped bend 702.

[0037] In this embodiment, the structure of the vent cap 703 is the same as that of the vent cap disclosed in CN218506089U, including a U-shaped tube section and a connecting tube section. The U-shaped tube section includes a bent section and tube bodies at both ends of the bent section. The bent section of the U-shaped tube section is connected to the connecting tube section, and the connecting tube section is connected to the U-shaped elbow 702. Under the premise of effectively eliminating the influence of the external working environment on the measurement results, the measuring tube 301 is connected to the atmosphere, so that the liquid level in the measuring tube 301 can be consistent with the sea level.

[0038] In a specific embodiment, the cap 701 is detachably connected to the top of the measuring tube 301. In practical applications, the cap 701 can be fastened to the top of the measuring tube 301; or, both the cap 701 and the measuring tube 301 are provided with flanges, and the two are connected by the flanges.

[0039] In a specific embodiment, the float 304 is made of polystyrene, which is lightweight and water-resistant, and can effectively ensure the buoyancy of the float 304.
