For those of ordinary skill in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] The following will be described with reference to Figures 1 to 4The application discloses a tilt angle measuring tool and a ship.

[0026] Referring to Figures 1 to 3 As shown in the drawings, the embodiment of the first aspect of the application provides a tilt angle measuring tool, which comprises a tilt angle sensing part 6, a support part and a warning part. The support part is fixed to the ship body, and the support part comprises a test platform 1. The tilt angle sensing part 6 is detachably arranged on the test platform 1. The warning part is in communication connection with the tilt angle sensing part 6, so that when the warning part receives the inclination information collected by the tilt angle sensing part 6 and the inclination information exceeds a threshold value, the warning part can give a warning.

[0027] The tilt angle measuring tool provided according to the above technical features integrates the three core functions of “sensing, fixing and warning” in the same tool. First, by arranging the support part with a test platform, the sensor is fixed to the ship body, which ensures the installation stability of the tilt angle sensing part 6, avoids the position deviation caused by the vibration of the ship, and reduces the measurement deviation caused by loose installation. Second, by establishing a standard measurement reference through the unified test platform, the inclination of the sensing part is synchronized with the posture of the ship body, which significantly improves the reference accuracy of the tilt angle measurement and lays a structural foundation for subsequent high-precision detection. The tilt angle sensing part 6 is detachably arranged on the test platform, which reduces the maintenance difficulty and cost. During maintenance, the fixed support does not need to be disassembled, and the replacement / calibration of the single sensing part can avoid long-term interruption of monitoring. Third, the warning part is in communication connection with the tilt angle sensing part 6, and a warning is given when the inclination information exceeds the threshold value. This eliminates the delay of manual response, ensures that the operator can detect the tilt risk in the first time, and timely starts the preventive measures such as ballast water adjustment and suspension of loading and unloading operation. Through automatic threshold judgment and active alarm, the false alarm caused by the observation negligence and insufficient experience of personnel is avoided, and the reliability of risk identification is improved.

[0028] Optionally, the tilt angle sensing part 6 can be a tilt angle sensor, such as a MEMS capacitive sensor, a MEMS piezoelectric sensor, a liquid pendulum sensor, an optical fiber sensor, etc.

[0029] Optionally, the warning part can be a warning light, a buzzer, a display screen, etc.

[0030] Optionally, as shown in the drawings, the tilt angle measuring tool can further comprise an electricity storage part, which can be in electrical connection with the tilt angle sensing part 6 and the warning part, so as to provide power for the work of the tilt angle sensing part 6, and the use of the tilt angle measuring tool is not limited by the power supply of the site.

[0031] Optionally, the electricity storage part can be arranged on the base 3.

[0032] Optionally, the electricity storage part can be a battery with a charging function, so as to realize the recycling of the electricity storage part.

[0033] Preferably, as shown in Figures 1 to 4 The support part can further include a base 3, a clamping assembly 4, and a plurality of adjusting struts 2, one end of the adjusting struts 2 being connected to the test platform 1, and the other end of the adjusting struts 2 being connected to the base 3. The clamping assembly 4 is arranged on the test platform 1 and is used to clamp the inclination angle sensing part 6. In this way, on the one hand, the clamping assembly 4 forms a circumferential constraint on the inclination angle sensing part 6, avoiding displacement or rotation caused by vibration, achieving quick mounting and dismounting of the inclination angle sensing part 6, and improving measurement stability and maintenance efficiency; on the other hand, the adjusting struts 2 are used as an intermediate body connecting the test platform 1 and the base 3, and the space posture of the test platform 1 can be changed by length / angle adjustment, so that the test platform 1 can still maintain a horizontal reference on a rough deck; and the base 3 is used as a direct connecting component with the ship body, increasing the force receiving area, increasing the stability of the inclination angle measuring tool, reducing the conduction of ship body vibration to the test platform 1, and further reducing the vibration interference of the sensing part.

[0034] Preferably, as shown in Figure 1 and Figure 4 The clamping assembly 4 can include a clamping piece 42 and two clamping plates 41 arranged opposite to each other along a first direction F1, and the clamping piece 42 is in transmission connection with the clamping plates 41 to apply a clamping force of approaching each other to the two clamping plates 41. In this way, the inclination angle sensing part 6 is clamped by the two clamping plates 41, and the two clamping plates 41 apply force synchronously from opposite directions to balance the force on the sensing part, avoid inclination caused by one-sided fixation, ensure that the axis of the sensing part is strictly perpendicular to the test platform 1, and further improve the accuracy of the measurement reference.

[0035] As shown in Figures 1 to 4 F1 shown in the figure can be an example of the first direction F1.

[0036] Preferably, as shown in Figure 1 and Figure 4 The clamping piece 42 is an example of a spring, which applies a clamping force of approaching each other to the two clamping plates 41 by the elastic force of the spring, instead of traditional bolt fixation, and the adjustment process does not need to disassemble the components, effectively improving the maintenance efficiency. However, the clamping piece 42 is not limited to the example of the spring, and the clamping piece 42 can also be a lead screw in threaded connection with the clamping plates 41, so as to realize the approaching and moving away of the clamping plates 41 by the rotation of the lead screw.

[0037] Preferably, the clamping part 42 can be embedded in the test platform 1, in other words, the test platform 1 can be provided with a groove for accommodating the clamping part 42, so that the clamping part 42 can be hidden inside the test platform 1, not only improving the neatness of the inclination angle measurement tool, but also ensuring good adhesion of the inclination angle sensing part 6 to the surface of the test platform 1, to avoid the influence of the clamping part 42 on the horizontality of the inclination angle sensing part 6.

[0038] Preferably, as shown in Figure 1 and Figure 4 , the test platform 1 can be provided with a slide 11 extending in the first direction F1, and the clamping plate 41 is in sliding connection with the slide 11, so that on the one hand, the connection and fixation between the clamping plate 41 and the test platform 1 are realized, and the sliding track accuracy of the clamping plate 41 is effectively improved; on the other hand, the cooperation of the slide 11 and the sliding clamping plate 41 makes the spacing between the two clamping plates 41 adjustable in the first direction F1, thereby making the support part adaptable to inclination angle sensing parts 6 of different models, solving the problem of poor universality of "fixed size clamping structure", and improving the compatibility of the tool to the sensor.

[0039] Preferably, as shown in Figure 1 and Figure 4 , the number of the slide 11 is two, and the two ends of the clamping plate 41 are in sliding connection with the two slides 11 respectively, to ensure the stability of the sliding of the clamping plate 41 and the uniformity of the clamping force distribution of the clamping plate 41.

[0040] Preferably, as shown in Figure 3 , the slide 11 can be formed as a sliding groove recessed in the test platform 1, in other words, at least part of the clamping plate 41 is clamped in the sliding groove, realizing the sliding connection between the clamping plate 41 and the test platform 1, thereby avoiding the influence of the slide 11 on the contact between the inclination angle sensing part 6 and the surface of the test platform 1, ensuring good adhesion of the inclination angle sensing part 6 to the surface of the test platform 1, to avoid the influence of the slide 11 on the horizontality of the inclination angle sensing part 6.

[0041] In the embodiment, as shown in Figures 1 to 4 , the base 3 can include a bottom plate 31 for fixed connection with the hull, so that the contact area with the hull can be effectively increased through the bottom plate 31, avoiding displacement of the base 3 in vibration, providing a stable basis for angle adjustment, and ensuring that the posture of the test platform 1 after adjustment does not rebound.

[0042] Preferably, as shown in Figures 1 to 3 , a magnetic member 33 is embedded on the side of the bottom plate 31 opposite the angle adjuster 32, so that the bottom plate 31 can be temporarily adsorbed to the surface of the hull steel structure without bolts, realizing quick fixation of the inclination angle measurement tool to the hull, and facilitating temporary adjustment and monitoring.

[0043] Preferably, as shown in Figures 1 to 4 the above-mentioned hull can also be provided with locking buckles 5, which can be buckled with the bottom plate 31. In this way, on the one hand, by buckling with the pre-set locking buckles 5 of the hull, the bottom plate 31 is prevented from sliding when the ship is vibrating, ensuring the fixing strength and solving the problem of "simple magnetic attraction is easy to fall off under strong vibration". On the other hand, there is no need to punch holes in the hull, avoiding the damage to the deck anticorrosion layer, reducing the risk of salt spray corrosion, prolonging the service life of the hull; At the same time, it avoids the problem of rusting of the bolt, effectively shortens the disassembly time of the inclined angle measurement tooling.

[0044] Preferably, as shown in Figure 2 and Figure 3 the above-mentioned locking buckle 5 is shown as an example of C-shaped clamp. Correspondingly, the corresponding position of the above-mentioned bottom plate 31 can be provided with a clamping groove 34 matched with the C-shaped clamp, so as to further improve the locking stability of the locking buckle 5 and the positioning accuracy of the locking buckle 5.

[0045] Preferably, as shown in Figure 1 and Figure 4 the above-mentioned bottom plate 31 can be a square plate, and the above-mentioned locking buckle 5 can be arranged at the four corners of the square plate to ensure the locking stability.

[0046] In the embodiment, preferably, as shown in Figures 1 to 3 the above-mentioned base 3 can also include an angle adjuster 32, which is fixedly arranged on the bottom plate 31, and the supporting rod 2 is connected with the base 3 via the angle adjuster 32. In this way, by adjusting the rotation of the supporting rod 2 around the angle adjuster 32, the inherent inclination of the hull mounting surface can be offset, so that the test platform 1 always keeps parallel with the design level of the hull, solving the problem of "reference deviation caused by the inclination of the mounting surface" and eliminating systematic measurement error.

[0047] Preferably, as shown in Figure 2 and Figure 3As shown, the angle adjuster 32 may include a hinge shaft 322, a locking bolt 324, and two limiting plates 321. The two limiting plates 321 are positioned opposite each other and spaced apart along the second direction F2, and at least a portion of the adjusting strut 2 is located between the two limiting plates 321. The hinge shaft 322 passes through all the adjusting struts 2 sequentially along the second direction F2, and both ends of the hinge shaft 322 are connected to the two limiting plates 321 respectively. The limiting plate 321 is provided with an arc-shaped groove 323, which passes through the limiting plate 321 along the second direction F2. The arc-shaped groove 323 is an arc groove with the hinge shaft 322 as the axis. The locking bolt 324 passes through the arc-shaped grooves 323 of the two limiting plates 321 and at least one adjusting support rod 2 to fix the adjusting support rod 2. In this way, on the one hand, the arc-shaped groove 323 with the hinge shaft 322 as the center ensures that the adjusting support rod 2 rotates only along the preset arc trajectory, improving the adjustment accuracy; on the other hand, after the locking bolt 324 passes through the two limiting plates 321 and the adjusting support rod 2, it is tightened and the adjustment angle is locked by friction, ensuring the long-term stability of the posture of the test platform 1.

[0048] like Figures 1 to 4 As shown in the figure, F2 can be an example of the second direction F2 mentioned above, such as... Figures 1 to 4 As shown in the figure, an example is illustrated where the second direction F2 and the first direction F1 are perpendicular to each other. However, this is not the only example. As long as both the first direction F1 and the second direction F2 are on the horizontal plane of the ship's design, they can be parallel or intersecting. For ease of description, the direction perpendicular to the horizontal plane of the ship's design is defined as the third direction F3. The F3 shown in the figure can be an example of the third direction F3.

[0049] Preferably, such as Figure 3 As shown, the angle adjuster 32 may include a connecting plate 325, and the two limiting plates 321 are connected via the connecting plate 325. The bottom of the connecting plate 325 is attached and fixed to the base plate 31 (e.g., by welding, bonding, etc.).

[0050] Preferably, such as Figure 3 As shown, the connecting plate 325 and the two limiting plates 321 can be bent into one piece to ensure the connection stability of the angle adjuster 32.

[0051] Optionally, the aforementioned limiting plate 321 may also be provided with an angle scale, which can be set along the arc-shaped slide groove 323, so that the operator can intuitively grasp the adjustment amount without the need for additional tools to measure, thereby improving the adjustment efficiency.

[0052] like Figure 2As shown in the figure, taking the example of three adjusting struts 2, the figure also shows an example of one locking bolt 324. In other words, all three adjusting struts 2 shown in the figure are fixed by the locking bolt 324. However, it is not limited to this. The number of locking bolts 324 can also be two (that is, two of the three adjusting struts 2 are fixed by one locking bolt 324, and the other of the three adjusting struts 2 is fixed by another locking bolt 324) or three (that is, the three adjusting struts 2 are fixed by three locking bolts 324 respectively) to accommodate different angle adjustment situations.

[0053] Preferably, such as Figures 1 to 3 As shown, the length of the aforementioned adjusting strut 2 is adjustable. On the one hand, by adjusting the adjusting strut 2 in conjunction with angle adjustment, the test platform 1 can be adjusted in height and attitude within a larger space range to meet the installation requirements of different positions on the hull (such as the deck, cargo hold edge, and bridge). On the other hand, when the hull mounting surface has a large tilt angle, the test platform 1 can be leveled by adjusting the length difference of different struts (in conjunction with angle adjustment), thus expanding the applicable scenarios of the tooling. In addition, the length of the struts can be shortened in the non-working state to reduce the space occupied by the tooling and facilitate storage and transportation.

[0054] Optionally, such as Figures 1 to 3 As shown, the aforementioned adjusting strut 2 may include a first part 21, a second part 22, and an adjusting screw 23, all extending in a predetermined direction. The adjusting screw 23 connects the first part 21 and the second part 22. At least one of the first part 21 and the second part 22 may be threadedly connected to the adjusting screw 23 to achieve the extension and retraction of the adjusting strut 2.

[0055] However, this is not the only limitation. The extension and retraction of the two adjusting rods 2 are not limited to the method of turning the adjusting screw 23. As long as the length of the adjusting rod 2 can be adjusted, the adjusting rod 2 can also be in other forms. For example, the adjusting rod 2 can be an inner rod and an outer rod that are nested and threaded together; or the adjusting rod 2 can be a nested inner and outer rod with a positioning pin for fixing; or the adjusting rod 2 can be an electric telescopic rod or other forms.

[0056] Preferably, such as Figures 1 to 3As shown, the adjusting support rod 2 can be hinged with the test platform 1, so that, on the one hand, the relative rotation between the adjusting support rod 2 and the test platform 1 is allowed, and when a single support rod is adjusted, the torque applied to the platform is avoided, the stress concentration of the rigid connection is eliminated, the fatigue damage risk of the connection part between the support rod and the platform is reduced, the service life of the tooling is prolonged, and the flatness of the test platform 1 is ensured; on the other hand, when multiple support rods are adjusted respectively, the hinge structure can automatically adapt to the height difference of each support rod, so that the test platform 1 is leveled horizontally through a small rotation, without the need for strict synchronous adjustment of all support rods, and the leveling operation is simplified.

[0057] Optionally, the adjusting support rod 2 and the test platform 1 can be hinged via a spherical hinge 24 to ensure the overall and unrestricted adjustment of the angle between the adjusting support rod 2 and the test platform 1.

[0058] Preferably, as shown, Figures 1 to 4 The number of the adjusting support rods 2 can be three, so as to ensure the flatness and support stability of the test platform 1, effectively reduce the difficulty of leveling the test platform 1, simplify the leveling operation of the test platform 1, and improve the installation efficiency of the inclination angle measuring tooling. However, the number of the adjusting support rods 2 can also be four, five or more, as long as the flatness and support stability of the test platform 1 are ensured.

[0059] Preferably, at least one of the multiple adjusting support rods 2 is in a curved rod structure, and specifically, as shown, Figure 3 The adjusting support rod 2 can further include a third part 25, which extends in a direction intersecting the predetermined direction, so as to form the curved rod structure. As shown, Figure 3 Two of the three adjusting support rods 2 are in the curved rod structure, so as to facilitate the assembly of the multiple adjusting support rods 2 in the angle adjuster 32. It should be noted that the number of the curved rod structures included in the multiple adjusting support rods 2 can be adjusted adaptively, as long as the interference of the multiple adjusting support rods 2 in the angle adjuster 32 is avoided.

[0060] Preferably, as shown, Figures 1 to 4 The multiple adjusting support rods 2 are arranged along the edge of the test platform 1, so as to ensure the stability of the support of the adjusting support rod 2 to the test platform 1.

[0061] Preferably, as shown, Figure 1 And Figure 4 The test platform 1 can be a circular platform, and the multiple adjusting support rods 2 can be uniformly distributed along the circumferential direction of the circular platform.

[0062] The embodiments of the second aspect of the present application also provide a ship comprising the inclination angle measuring tool according to any one of the above embodiments, thus having all the beneficial technical effects of the inclination angle measuring tool, which will not be repeated here.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the above embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
