Description

Technical Field

[0001] The present invention relates to the technical field of ships, and particularly to a magnetic adsorption type ship draft reading and wave eliminating water pipe. Background Art

[0002] The light ship weight of a ship is the most important index in shipbuilding, which directly determines the load capacity level of the ship. After the ship is built, an inclining test is required to determine the weight and the position of the center of gravity of the ship.

[0003] The calculation of the ship weight is to determine the drafts at the bow, middle and stern of the ship by reading the water gauges arranged at the bow, middle and stern on both sides of the ship respectively, and then calculate the light ship weight of the ship through a hydrostatic table, etc. The prior art mainly observes the draft height at the water gauge by the naked eye. However, due to the influence of external environment factors, there are always certain waves in the ship launching water area, and the water surface fluctuates up and down. It is very difficult to accurately read through naked eye observation. When the environmental conditions are worse, the test of the day will even be cancelled according to the requirements, delaying the time node and causing certain losses. Even if a wave eliminating water pipe is adopted, most of them are rigid glass water pipes. Due to the certain curved shape of the outer hull of the ship, it cannot be closely attached to the outer hull of the ship. Coupled with the naked eye observation from a distance, different results will be read at different heights and angles, resulting in deviation of the test.

[0004] The prior art has the following defects:

[0005] 1. Environmental factors may lead to the delay of the time node and cause certain losses;

[0006] 2. The waves cause the water surface to fluctuate up and down, making it impossible to accurately read the data, resulting in test errors;

[0007] 3. The existing rigid wave eliminating water pipes cannot fit the curved shape of the outer hull of the ship, resulting in deviation of the reading test. Summary of the Invention

[0008] The technical problem to be solved by the present invention is to overcome the above defects existing in the prior art and provide a magnetic adsorption type ship draft reading and wave eliminating water pipe.

[0009] The present invention solves the above technical problem by the following technical solutions:

[0010] A magnetic adsorption type ship draft reading and wave eliminating water pipe, which comprises a transparent hose. A groove is arranged on the back surface of the hose, and a plurality of magnets for adsorbing the hose to the outer hull of the ship are embedded in the groove. The magnets have magnetic adsorption ends that are not covered by the hose and can adsorb the hose to the outer hull of the ship.

[0011] In the cross-sectional view of the hose, the front surface of the hose is arc-shaped, and the back surface of the hose is rectangular.

[0012] The grooves are distributed along the length direction of the hose.

[0013] The groove is a T-shaped groove.

[0014] The width of the notch of the groove is smaller than the width of the bottom of the groove.

[0015] The magnet is a T-shaped magnet adapted to the groove.

[0016] The width of the bottom of the magnet is not less than the end of the bottom of the groove.

[0017] The end of the magnet clamped in the notch of the groove is the magnetic adsorption end of the magnet.

[0018] Both ends of the inner cavity of the hose are pipe orifices communicating with the outside.

[0019] The material of the hose is plastic or rubber.

[0020] The beneficial effect of the present invention is that: the present invention uses a hose and magnetic adsorption performance to make a wave-dissipating water pipe, which can be attached to the outer plate of the ship during use to eliminate the interference of external waves when the ship reads the draft, and can effectively reduce the influence of waves on the reading, so as to obtain more accurate draft data.

[0025] The following is a preferred embodiment and is described in more clearly and completely in conjunction with the drawings to illustrate the present invention.

[0026] As Figure 1 and Figure 2 shown, a magnetic adsorption type marine draft reading wave-dissipating water pipe includes a transparent hose 10, and the material of the hose 10 is plastic or rubber. A groove 11 is provided on the back of the hose, and a plurality of magnets 12 for adsorbing the hose to the outer plate of the ship are embedded in the groove 11. The magnet has a magnetic adsorption end that is not covered by the hose and can adsorb the hose to the outer plate of the ship.

[0027] In the cross-sectional view of the hose, the front of the hose 10 is arc-shaped and the back of the hose is rectangular.

[0028] The grooves 11 are distributed along the length direction of the hose.

[0029] In a preferred embodiment, the groove 11 is a T-shaped groove. The width of the groove opening is smaller than the width of the groove bottom.

[0030] The magnet 12 is a T-shaped magnet adapted to the groove. The width of the magnet bottom is not less than the end of the groove bottom. The end of the magnet clamped in the groove opening is the magnetic adsorption end of the magnet.

[0031] Both ends of the inner cavity of the hose 10 are pipe orifice parts communicating with the outside.

[0032] The material of the hose has a certain elasticity, and the shape of the magnet is adapted to the groove. In this way, the magnet can be clamped in the groove to adsorb the hose to the outer plate of the ship; in addition, the magnet can also slide in the groove to enable the hose to adapt to the shape of the outer plate of the ship and fit against the outer plate of the ship.

[0033] Due to the certain linear curvature of the outer plate of the ship, the magnet has a small width and a thin thickness, which can ensure the degree of fit between the magnet and the hull.

[0034] The actual application situation of the magnetic adsorption type ship draft reading and wave damping water pipe of the present invention is as Figure 3 and Figure 4 shown. Figure 4 It is a schematic cross-sectional view at the water gauge mark position. Figure 3 and Figure 4 In, a water gauge mark 24 is provided outside the outer plate 21 of the ship. Figure 4 In, the left side of the outer plate 21 of the ship represents the inside of the ship's cabin, and the right side of the outer plate 21 of the ship represents the water area.

[0035] When the ship conducts an inclination test, it is necessary to read the draft depth of the water gauge mark 24 relative to the theoretical water surface 22. However, due to external environmental factors, there are certain waves on the actual water surface 23 of the water area. During the test, visual observation is carried out with the naked eye, and the waves cause the water surface to rise and fall, making it difficult to observe accurate data.

[0036] The water gauge mark 24 located on the outer plate 21 of the ship is usually made by lofting and cutting a 6 mm steel plate and welded to the outer plate of the ship.

[0037] As Figure 3 and Figure 4 shown, the magnetic adsorption type ship draft reading and wave damping water pipe 20 of the present invention is closely attached to the water gauge mark 24 on the outer plate 21 of the ship through the magnet on the back of the hose.

[0038] The magnetic-absorption type marine draft-reading wave-dissipating water pipe 20 blocks the transmission of wave energy. Therefore, the liquid level inside the hose of this wave-dissipating water pipe is the actual theoretical water surface. A colored oil film 25 is arranged above the liquid level inside the hose cavity, which can clearly read the draft height at the water gauge, avoiding the error caused by different visual observation angles.

[0039] Since the wave transmission still has a certain depth underwater, the lower end of the wave-dissipating water pipe is preferably located below 1.0 m of the water surface. If the waves are larger, the underwater length can be further increased to minimize the influence of environmental factors on the ship's draft reading and ensure the smooth progress of the test.

[0040] The magnetic-absorption type marine draft-reading wave-dissipating water pipe of the present invention can be bent along the curve of the ship's outer plate, adsorbed on the ship's water gauge position by a magnet. The lower end of the water pipe is immersed in the water area and connected to the water area, and the upper end is connected to the air. Since the transmission of wave energy on the water surface does not affect the lower water area, the present invention can keep the liquid level inside the wave-dissipating water pipe as static as possible, minimizing the influence of environmental factors on the ship's draft reading and ensuring the smooth progress of the test. At the same time, it can be bent to fit the shape of the ship's outer plate to the greatest extent, accurately read the draft at the water gauge, and thus calculate a more accurate light ship weight.

[0041] The present invention uses a hose and magnetic-absorption performance to make a wave-dissipating water pipe, which can fit the ship's outer plate during use, eliminate the external wave interference when the ship reads the draft, effectively reduce the influence of waves on the reading, and obtain more accurate draft data.

[0042] Although the specific embodiments of the present invention have been described above, those skilled in the art should understand that this is only an example, and the protection scope of the present invention is defined by the appended claims. Without departing from the principle and essence of the present invention, those skilled in the art can make various changes or modifications to these embodiments, but these changes and modifications all fall within the protection scope of the present invention.
