Description

Technical Field

[0001] This invention relates to the field of measuring device technology, and more specifically to a practical draft measuring device. Background Technology

[0002] Accurate measurement of a ship's draft is crucial during its construction, operation, and maintenance. Draft not only affects navigational safety but also has a critical impact on cargo capacity calculations and navigation performance assessments. However, existing draft measurement methods suffer from the following problems: Firstly, there is manual measurement. Traditional manual measurement methods, such as observing water level gauge markings, are greatly affected by factors such as waves, lighting, and observation angle, resulting in low measurement accuracy and a high risk of error. In situations with large waves, the water surface fluctuates violently, making it difficult to accurately read the water level gauge markings. Moreover, during manual observation, the position and viewing angle of the observer can also lead to reading deviations.

[0003] Secondly, existing draft measuring instruments are complex in structure, expensive, and cumbersome to operate, making them unsuitable for widespread application in practical work. While some high-precision electronic measuring instruments offer high accuracy, they are also expensive and require significant maintenance, making them unaffordable for some small vessels or shipping companies with limited budgets. Furthermore, operating these instruments requires specialized technicians, increasing the difficulty of use and labor costs.

[0004] Therefore, a practical draft measuring device is needed, which can be easily measured using a simple device, thus avoiding errors from manual measurement and reducing the cost of use.

[0005] This invention proposes a practical draft measurement device to solve the above-mentioned problems. Summary of the Invention

Then, the limiting component is closed, thereby achieving a fixed connection between the fixing component and the ship's surface, and ensuring stable installation of the transparent plastic tube.

[0017] The following will refer to the appendices in the embodiments of the present invention. Figure 1-11 The technical solutions in the embodiments of the present invention are clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Example Please refer to Figures 1-11The present invention provides the following technical solution: a practical draft measuring device, comprising a transparent plastic tube 1, the transparent plastic tube 1 having a scale with the scale unit being millimeters, and including a flexible tube 2, a wave-damping float 3, a top cover 4, a camera 5, a mounting component 6, a fixing component 7, and a limiting component 8. The bottom end of the transparent plastic tube 1 is connected to and communicates with the flexible tube 2, and a counterweight 10 is installed at the bottom end of the flexible tube 2. The counterweight 10 includes a rope 1001 and counterweight blocks 1002. The outer wall of the bottom end of the flexible tube 2 is connected to the rope 1001, and the bottom end of the rope 1001 is connected to symmetrically distributed counterweight blocks 1002. The wave-damping float 3 is placed inside the transparent plastic tube 1, and the top end of the transparent plastic tube 1 is connected to the top cover 4. The top end of the top cover 4 has a vent hole 9, and the vent hole 9 is internally threaded and tightly connected. The sealing cap can be unscrewed to open the vent 9, so that the pressure inside and outside the transparent plastic tube 1 is consistent. A camera 5 is connected to the center side wall of the top cover 4. The camera 5 is used to photograph the draft scale position on the surface of the transparent plastic tube 1. Three sets of circumferentially arrayed mounting parts 6 are installed on the outer side wall of the transparent plastic tube 1. The mounting parts 6 include fixed blocks 601 and guide rods 602. The top and bottom ends of the transparent plastic tube 1 are connected to three circumferentially arrayed fixed blocks 601. The side wall of each set of fixed blocks 601 is connected to a guide rod 602. A fixing part 7 is movably set on the mounting part 6. The fixing part 7 is used to fix the transparent plastic tube 1 to the surface of the hull. A limiting part 8 is installed on the fixing part 7. The limiting part 8 is used to limit the movement of the fixing part 7.

[0019] A transparent plastic tube 1 is vertically inserted into the water outside the ship. Using a fixing piece 7, the transparent plastic tube 1 is fixed at a suitable height on the ship's surface. A limiting piece 8 is used to limit the fixing piece 7. At this time, the flexible tube 2 located below the transparent plastic tube 1 is in the water, and water enters the transparent plastic tube 1 from the flexible tube 2. The wave-damping buoy 3 can reduce the amplitude of water surface fluctuations to improve the accuracy of reading the draft scale. The scale of the transparent plastic tube 1 is used to measure the water level inside the transparent plastic tube 1, and a camera 5 is used to take a high-definition and accurate picture of the water level inside the transparent plastic tube 1 at the scale to avoid observation errors. The above operation is repeated multiple times, and the average value is taken to obtain a more accurate draft value, thereby achieving the effect of conveniently measuring the draft. The counterweight 1002, which is attached to the hose 2 by the rope 1001, helps the hose 2 to remain vertical underwater, preventing the hose 2 from bending or folding and causing slow water flow. The rope 1001 can also be removed from the hose 2, allowing the hose 2 to bend freely and be used according to the specific water conditions.

[0020] The specific use of fastener 7 is as follows: Please refer to Figure 4 , Figure 5 , Figure 7 , Figure 8 and Figure 9 The fixing component 7 includes a bracket 701, a guide hole 702, a rotating groove 703, a rotating shaft 704, a keyway ring 705, a magnet 706, a rubber pad 707, a fixed ring 708, a moving ring 709, and a bolt 710. The bracket 701 is Y-shaped. The top of the bracket 701 has a guide hole 702. A rotating groove 703 is formed on the side wall of a single end of the bracket 701. The side wall of the rotating groove 703 is rotatably connected to the rotating shaft 704. Both ends of the rotating shaft 704 are connected to keyway rings 705, which are also located on both sides of the single end of the bracket 701. One end of the rotating shaft 704 is connected to a magnet 706. A rubber pad 707 is connected to the outer wall of the magnetic block 706. Anti-slip grooves are provided on the surface of the rubber pad 707. Fixed rings 708 are connected to the end side walls of both ends of the bracket 701. Rotary rings 709 are rotatably connected to the side walls of the fixed rings 708. The fixed rings 708 and the rotary rings 709 are both semi-circular arc-shaped. Through holes are provided on the side walls of the fixed rings 708 and the rotary rings 709. Buffer pads are provided on the inner side walls of the fixed rings 708 and the side walls of the rotary rings 709. Bolt 710 passes through the through holes. Bolt 710 includes a bolt and a nut. The bolt passes through the through holes, and the nut is threaded onto the side wall of the bolt.

[0021] Please refer to Figure 5 , Figure 7 , Figure 8 and Figure 10 The limiting component 8 includes a side plate 801, a self-locking screw 802, a screw hole 803, a sliding hole 804, a sliding rod 805, and a key 806. The side plate 801 is located on both sides of a single end of the bracket 701. The side wall of the side plate 801 is rotatably connected to the self-locking screw 802. The side walls of both sides of the single end of the bracket 701 are provided with screw holes 803, which are threadedly connected to the self-locking screw 802. The side walls of both sides of the single end of the bracket 701 are also provided with sliding holes 804. The side wall of the side plate 801 is connected to the sliding rod 805, and the side wall of the sliding rod 805 is slidably connected to the sliding hole 804. One side wall of the side plate 801 is provided with a key 806, which is inserted and engaged with the keyway ring 705.

[0022] Depending on the ship's height, the height of the fixing component 7 on the guide rod 602 is adjusted. Specifically, the bracket 701 is moved up and down along the guide rod 602 to move the fixing component 7 up and down as a whole, so that the magnet 706 can fit against the surface at a suitable ship height. Then, the moving ring 709 and the fixed ring 708 are attached and clamped to the guide rod 602 on both sides. Then, the through holes are aligned, and the bolt 710 is inserted into the aligned through holes, so that the bolt 710 tightly clamps the moving ring 709 and the fixed ring 708 to fix the guide rod 602, thereby fixing the entire fixing component 7 on the guide rod 602, and thus achieving a fixed connection between the fixing component 7 and the transparent plastic tube 1 as a whole. At this time, the limiting member 8 is opened, so that the magnetic block 706 can drive the rotating shaft 704 to rotate. The rotating shaft 704 drives the keyway ring 705 to rotate. With the multiple keyways provided in the keyway ring 705, the rotating shaft 704 can be fixed by the limiting member 8 at multiple rotation angles, so that the magnetic block 706 can fit against the inclined surface of the ship surface, and the magnetic block 706 can better fit and adhere to the ship surface. Then, the limiting member 8 is closed, thereby achieving the effect of fixing the fixing member 7 to the ship surface and achieving the effect of stable installation of the transparent plastic tube 1. The specific operating steps of the limiting component 8 are as follows: Rotate the self-locking screw 802 to make the self-locking screw 802 drive the side plate 801 to move back and forth (refer to...). Figure 5 The side plate 801 can move stably in a straight line through the sliding rod 805 and the sliding hole 804. At the same time, the side plate 801 also drives the key 806 to move back and forth (see reference). Figure 5 This allows the key 806 to be inserted into and detached from the keyway on the keyway ring 705, thereby limiting and opening the keyway ring 705, and ultimately fixing and allowing the rotating shaft 704 to rotate freely.

[0023] Please refer to Figure 11 The keyway ring 705 is installed as follows: four symmetrically distributed insert blocks 11 are connected to the inner ring sidewall of the keyway ring 705. Four symmetrically distributed slots 12 are opened on both ends of the rotating shaft 704. The slots 12 are inserted and connected to the insert blocks 11. Mounting holes 13 are opened on both ends of the rotating shaft 704. Screws 14 are threadedly connected to the sidewall of the mounting holes 13. The sidewall of the screws 14 fits tightly with the keyway ring 705, so that the keyway ring 705 can be tightly fixed together with the rotating shaft 704. Furthermore, removing the screws 14 can also easily remove the keyway ring 705 for easy replacement.

[0024] The working principle and usage process of this invention are as follows: In specific use, the transparent plastic tube 1 is vertically inserted into the water outside the ship. The fixing part 7 is used to fix the transparent plastic tube 1 at a suitable height on the ship surface. The limiting part 8 is used to limit the fixing part 7. At this time, the hose 2 located below the transparent plastic tube 1 is in the water. Water enters the transparent plastic tube 1 from the hose 2. The wave-damping float 3 can reduce the fluctuation amplitude of the water surface to improve the accuracy of reading the draft scale. The scale of the transparent plastic tube 1 is used to measure the water level inside the transparent plastic tube 1. The camera 5 is used to take a high-definition and accurate picture of the water level inside the transparent plastic tube 1 at the scale to avoid observation errors. The above operation is repeated multiple times and the average value is taken to obtain a more accurate draft value, thereby achieving the effect of conveniently measuring the draft. Depending on the ship's height, the height of the fixing component 7 on the guide rod 602 is adjusted. Specifically, the bracket 701 is moved up and down along the guide rod 602 to move the fixing component 7 up and down as a whole, so that the magnet 706 can fit against the surface at a suitable ship height. Then, the moving ring 709 and the fixed ring 708 are attached and clamped to the guide rod 602 on both sides. Then, the through holes are aligned, and the bolt 710 is inserted into the aligned through holes, so that the bolt 710 tightly clamps the moving ring 709 and the fixed ring 708 to fix the guide rod 602, thereby fixing the entire fixing component 7 on the guide rod 602, and thus achieving a fixed connection between the fixing component 7 and the transparent plastic tube 1 as a whole. At this time, the limiting member 8 is opened, so that the magnetic block 706 can drive the rotating shaft 704 to rotate. The rotating shaft 704 drives the keyway ring 705 to rotate. With the multiple keyways provided in the keyway ring 705, the rotating shaft 704 can be fixed by the limiting member 8 at multiple rotation angles, so that the magnetic block 706 can fit against the inclined surface of the ship surface, and the magnetic block 706 can better fit and adhere to the ship surface. Then, the limiting member 8 is closed, thereby achieving the effect of fixing the fixing member 7 to the ship surface and achieving the effect of stable installation of the transparent plastic tube 1. The specific operating steps of the limiting component 8 are as follows: Rotate the self-locking screw 802 to drive the side plate 801 to move back and forth. Through the sliding rod 805 and the sliding hole 804, the side plate 801 can move stably in a straight line. At the same time, the side plate 801 also drives the key 806 to move back and forth, so as to realize the insertion and disengagement of the key 806 and the keyway ring 705, thereby achieving the effect of limiting and opening the keyway ring 705, and thus achieving the effect of fixing and freely rotating the rotating shaft 704.
