Description

Technical Field

[0001] This utility model relates to the field of shipbuilding measurement readings, specifically a seaworthy ship draft gauge. Background Technology

[0002] In shipbuilding, the empty ship weight data obtained from inclining and weighing tests is an important design indicator for a ship. It has always been obtained through floating weighing. However, the water environment is not calm. Each reading is affected by the waves, with an error of about 5 centimeters. For a large cargo ship, such a deviation can result in a weight loss of nearly 300 tons.

[0003] Traditional reading gauges are operated with both ends closed, resulting in a fixed value that differs significantly from the actual reading, leading to substantial reading errors. Furthermore, the components of these reading gauges were relatively rigid, which is problematic since ship hulls are not always flat, making them difficult to fix in place during use.

[0004] In document CN 117985195 B, a hydrostatic level gauge-assisted ship draft reading device is disclosed, including a hydrostatic level gauge (1) for measuring liquid level; a measuring sensor component (2) fixedly installed on the output end of the hydrostatic level gauge (1), the measuring sensor component (2) including a connecting cable (21) fixedly installed on the output end of the hydrostatic level gauge (1), a sensor probe (22) fixedly installed at the bottom of the connecting cable (21) for sensing changes in liquid level, and a screen plate (23) fixedly installed at the bottom of the sensor probe (22) for isolating external impurities; and a wave-damping mechanism (3) for reducing underwater fluctuations from the measurement, and the wave-damping mechanism (3) is fixedly installed outside the measuring sensor component (2). If both ends of this structure are sealed, the accuracy is poor.

[0005] Therefore, a new technical solution is needed to solve the above-mentioned technical problems. Summary of the Invention

[0006] To address the aforementioned issues, this utility model discloses a seaworthy draft gauge for ships, which improves the accuracy of reading ship draft and reduces cargo transportation losses. The flexible components can improve the fit between the gauge and the ship's outer plating and are not limited by different types of lines.

[0007] The technical solution of this utility model is as follows: a wave-resistant ship draft gauge, including a steel ruler, a visible water tank, an air duct and a throttle valve. The visible water tank and the steel ruler are both fixed by a guide clamp. The upper end and the lower end of the visible water tank are respectively connected to the air duct and the diving guide pipe. The air duct is equipped with a throttle valve, and the diving guide pipe is placed in the water.

[0008] By adopting the above technical solution, the reading meter is placed in the water, and then water enters the visible water tank through the submersible guide pipe. The throttle valve is turned off to control the air pressure and lock the liquid in the visible water tank. The readings of high and low liquid levels can be counted to obtain accurate draft data.

[0009] Preferably, the guide clamps are placed at the upper, middle and lower parts of the steel ruler, and the guide clamps are provided with cavities for the steel ruler, the visible water tank and the high-strength magnet to pass through.

[0010] By adopting the above technical solution, the guide clamp precisely holds the entire assembly, ensuring that the entire assembly is firmly against the hull during readings, and that the components inside the guide clamp remain completely secure.

[0011] Preferably, the side of the guide clamp away from the steel ruler is an outward arc shape, and the side of the guide clamp close to the steel ruler is attached to the surface of the steel ruler. The guide clamp is integrally formed.

[0012] By adopting the above technical solution, the guide clamp is arc-shaped. When the ship is navigating in the water, the arc shape reduces the overall water resistance and reduces the damage to the reading instrument caused by water resistance during navigation.

[0013] Preferably, the high-strength magnet is placed between the visible water tank and the steel ruler, with the high-strength magnet located on both sides of the steel ruler in the vertical direction. The high-strength magnet is a permanent magnet with a thickness of 2 mm.

[0014] By adopting the above technical solution, the high-strength magnet can magnetically attract the entire reading meter to the ship. When replacement is needed, the high-strength magnet can be removed from the hull without damaging the hull or the reading meter.

[0015] Preferably, the throttle valve is a two-way airtight valve with an M8 mm diameter, and the throttle valve side is in a manual hand-held state.

[0016] By adopting the above technical solution, after the throttle valve is closed, the air pressure in the air pipe can lock the liquid in the visible water tank, making it convenient to read the high and low liquid levels, thereby obtaining more accurate draft data.

[0017] Preferably, the air duct is a high-transparency acrylic flexible tube with a diameter of 8 mm.

[0018] By adopting the above technical solution, the air guide tube is a flexible hose with a certain degree of flexibility, which makes it convenient to hold the throttle valve part by hand.

[0019] Preferably, the visible water tank is a high-transparency acrylic hose with a diameter of 36 mm.

[0020] By adopting the above technical solution, it has excellent bending and toughness, and can adapt to different ship shapes. The ship's outer plate is not entirely a flat area, and the flexible material can adapt better and is not easy to break.

[0021] Preferably, the submersible guide tube is a high-transparency acrylic flexible tube with a diameter of 15 mm.

[0022] By adopting the above technical solution, the submersible guide pipe is a flexible hose. When the submersible guide pipe is stored in water, it will not be bent or damaged due to its good flexibility.

[0023] The advantages of this utility model are as follows: 1. By setting a throttle valve at one end of the reading meter and keeping the submersible guide pipe always open, the liquid level in the water tank can be displayed in real time, and the highest and lowest values ​​of the liquid level can be read to obtain the intermediate value. This results in higher accuracy, avoids cargo loss on the cargo ship, and increases profits.

[0024] 2. The steel ruler and the visible water tank of this utility model are all flexible components. The outer plate of a ship is not always straight. The flexible components can be well attached to the outer plate of the ship, without being restricted by the outer plate shape. Measurements can be taken in waters with large waves, without being affected by the environmental water, and the measurement data is accurate.

[0025] 3. The guide clamp of this utility model is generally outward arc-shaped, which reduces the resistance between the guide clamp and the water flow, thereby reducing the overall resistance of the device, reducing wear and tear, and extending the service life. Attached Figure Description

[0029] The components include: 1. Steel ruler, 2. Visual water tank, 3. Diving guide pipe, 4. Air guide pipe, 5. Throttle valve, 6. High-strength magnet, and 7. Guide clamp. Detailed Implementation

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0031] like Figure 1-3 As shown, a seaworthy draft gauge for ships includes a steel draft gauge 1, a visible water tank 2, an air duct 4, and a throttle valve 5. The visible water tank 2 and the steel draft gauge 1 are both fixed by a guide clamp 7. The upper and lower ends of the visible water tank 2 are connected to the air duct 4 and the submersible guide pipe 3, respectively. The air duct 4 is equipped with a throttle valve 5. The submersible guide pipe 3 is placed in the water, and the draft gauge is placed in the water. Then, water enters the visible water tank 2 from the submersible guide pipe 3. By closing the throttle valve 5, the liquid in the visible water tank 2 is locked by controlling the air pressure. The high and low liquid level readings can be counted to obtain accurate draft data.

[0032] The guide clamps 7 are respectively placed at the upper, middle, and lower parts of the steel ruler 1. The guide clamps 7 have cavities for the steel ruler 1, the visible water tank 2, and the high-strength magnet 6 to pass through. The guide clamps 7 clamp the entire assembly, ensuring that the entire assembly is firmly against the hull during readings. The components inside the guide clamps 7 are completely secure.

[0033] The side of the guide clamp 7 away from the steel ruler 1 is an outward arc shape, and the side of the guide clamp 7 close to the steel ruler 1 is attached to the surface of the steel ruler 1. The guide clamp 7 is integrally formed and the whole guide clamp 7 is arc-shaped. In this way, when the ship is sailing in the water, the arc-shaped appearance reduces the overall water resistance and reduces the damage to the reading instrument caused by water resistance during navigation.

[0034] The high-strength magnet 6 is positioned between the visible water tank 2 and the steel ruler 1. The high-strength magnet 6 is located on both sides of the steel ruler 1 in the vertical direction. The high-strength magnet 6 is a permanent magnet with a thickness of 2 mm. The high-strength magnet 6 can magnetically attract the entire reading meter to the ship. When it needs to be replaced, the high-strength magnet 6 can be removed from the hull without damaging the hull or the reading meter.

[0035] Throttle valve 5 is a two-way airtight valve with an M8 mm diameter. Throttle valve 5 is manually operated. After throttle valve 5 is closed, the air pressure in the air pipe 4 can lock the liquid in the visible water tank 2, making it convenient to read the high and low liquid levels, thereby obtaining more accurate draft data.

[0036] The air guide tube 4 is a high-transparency acrylic flexible tube with a diameter of 8 mm. The air guide tube 4 is a flexible tube with a certain degree of flexibility, which makes it convenient to hold the throttle valve 5 by hand.

[0037] The visible water tank 2 is made of high-transparency acrylic flexible hose with a diameter of 36 mm. It has good flexibility and toughness and can adapt to different ship hulls. The flexible material can better adapt to areas where the ship's outer plate is not entirely flat and is not easy to break.

[0038] The submersible guide tube 3 is a high-transparency acrylic flexible tube with a diameter of 15 mm. As a flexible tube, the submersible guide tube 3 will not be bent or damaged when stored in water due to its good flexibility.

[0039] The ship's draft gauge is placed on the ship's outer plating. Because the steel gauge 1 and the visible water tank 2 have good bending and toughness, they can freely adhere to the curvature of the ship's outer plating even if the outer plating is not entirely flat. The deeper the diving guide pipe 3 is inserted into the large wave fluid, the more stable the liquid level changes in the visible water tank 2 that enters through the guide pipe 3. The liquid level in the visible water tank 2 changes periodically over a certain period of time. By closing the throttle valve 5 and controlling the air pressure to lock the liquid in the visible water tank 2, the high and low liquid level readings can be counted, the intermediate value can be calculated, and accurate draft data can be obtained.

The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments.
