Description

Technical Field

[0001] The present invention relates to the technical field of ship testing, and in particular to a device for monitoring displacement of an intermediate bearing of a ship output shaft and a ship. Background Art

[0002] As ships grow larger, their propulsion shafts become longer, requiring more and more intermediate bearings. During navigation, the ship's hull deforms to varying degrees due to environmental factors such as wind, waves, and surge, as well as varying ballast and cargo loads. Since the intermediate bearings are fixed to the hull, they also shift with this deformation. This displacement primarily involves displacement and rotation in the ship's width and height.

[0003] On typical ships, due to the short propulsion shafting, the displacement of the intermediate bearing caused by hull deformation is minimal and negligible. However, for ships with extra-long propulsion shafting, the displacement of the intermediate bearing can significantly affect the shafting deflection and the distribution and magnitude of the oil film force on the intermediate bearing. Under certain speeds and intense ship maneuvers, this can cause severe wear of the intermediate bearing, potentially damaging the entire propulsion shafting and impacting ship operation and safety.

[0004] However, existing ship monitoring devices can only measure the deformation of the propulsion shaft system in real time. Since the displacement of the intermediate bearing is caused by the deformation of the hull, the ship monitoring device cannot measure the displacement parameters of the intermediate bearing based on the hull, and cannot provide data reference for ship operation. The intermediate bearing is easily damaged. Summary of the Invention

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0026] In order to solve the technical problems in the prior art that the ship monitoring device cannot measure the displacement parameters of the intermediate bearing based on the hull, cannot provide data reference for ship operation, and the intermediate bearing is easily damaged, the present invention provides a ship output shaft intermediate bearing displacement monitoring device, which can measure the offset angle and offset amount of the intermediate bearing on the ship output shaft, provide data reference for ship operation, and set a reasonable ship operation plan in advance to protect the intermediate bearing.

[0027] It should be noted that the ship output shaft intermediate bearing displacement monitoring device described in the present invention is used for but not limited to ships, etc. For the convenience of explanation, in the present invention, only the ship output shaft intermediate bearing displacement monitoring device is used in ships as an example for explanation. The principle of applying the ship output shaft intermediate bearing displacement monitoring device to other types of equipment is essentially the same as the principle of applying it to ships, and will not be described in detail here.

[0028] See also Figure 1 , Figure 1 This is a structural schematic diagram of a ship output shaft intermediate bearing displacement monitoring device in one embodiment of the present invention. The ship output shaft intermediate bearing displacement monitoring device includes a reference measurement component 1, an on-site measurement component 2 and a data acquisition and processing component 3. The reference measurement component 1 includes a main sensor 11 and a main transmitter 12. The on-site measurement component 2 includes a sub-sensor 23, a receiver 21 and a sub-transmitter 22. The sub-sensor 23 and the main sensor 11 are both used to measure the ship angle at their respective corresponding positions. The receiver 21 is used to receive infrared rays emitted by the main transmitter 11.

[0029] The data acquisition and processing component 3 is connected to the reference measurement component 1 and the on-site measurement component 2, and is used to calculate the ship angle difference measured by the main sensor 11 and the auxiliary sensor 23, and calculate the displacement difference between the main transmitter 12 and the auxiliary transmitter 23.

[0030] In this embodiment, both the primary sensor 11 and the secondary sensor 23 are IMU sensors, each used to measure the angle of the ship at their location. The difference between the ship angles measured by the two sensors is the offset angle. Therefore, the primary sensor 11 and the secondary sensor 23 can be placed on the intermediate bearings 40 at both ends of the output shaft to measure the offset angles of these intermediate bearings 40.

[0031] Both the main transmitter 12 and the auxiliary transmitter 22 are ultra-fine infrared transmitters, capable of emitting ultra-fine infrared rays. The receiver 21 is used to receive the ultra-fine infrared rays emitted by the main transmitter 12 or the auxiliary transmitter 22. The main transmitter 12 or the auxiliary transmitter 22 can be positioned on one of the intermediate bearings 40, and the receiver 21 can be positioned on the other adjacent intermediate bearing 40. The ultra-fine infrared rays emitted by the main transmitter 12 or the auxiliary transmitter 22 can be received by the receiver 21. It is important to emphasize that the receiver 21 has a large receiving area. Even if the receiver 21 is offset by a certain distance, and given that the infrared rays are ultra-fine, the receiver 21 can still receive the emitted ultra-fine infrared rays. The data acquisition and processing component 3 can calculate the offset distance of the ultra-fine infrared rays.

[0032] See also Figure 2 , Figure 2 The output shaft 4 of the illustrated embodiment is provided with two intermediate bearings, namely a first intermediate bearing 5 and a second intermediate bearing 6. The first intermediate bearing 5 and the second intermediate bearing 6 are both provided with on-site measurement assemblies, which for the convenience of description are defined as a first measurement assembly 7 and a second measurement assembly 8, respectively. The output shaft 4 is connected to a drive motor 9 and is driven to rotate by the drive motor 9. The reference measurement assembly 1 is mounted and fixed next to the output shaft 4, and the main transmitter 12 of the reference measurement assembly 1 is aligned with the receiver 21 of the first measurement assembly 7 so that the extremely fine infrared rays emitted by the main transmitter 12 can be received by the receiver 21. When the first intermediate bearing 5 or the second intermediate bearing 6 is offset, the first intermediate bearing 5 or the second intermediate bearing 6 will inevitably be offset relative to the reference measurement assembly 1. The offset distance in the longitudinal direction of the output shaft 4 is L1. The value of L1 can be sensed by the extremely fine infrared rays emitted by the main transmitter 12 of the reference measurement assembly 1 being received by the receiver 21 of the first measurement assembly 7. The angle of the offset of the first intermediate bearing 5 can be sensed by the auxiliary sensor 23 of the first measurement assembly 7, for example Figure 2 In the embodiment shown, the offset angle of the first intermediate bearing 5 is R1.

[0033] The first measuring assembly 7 also includes a sub-transmitter 22. Sub-transmitter 22 emits ultra-thin infrared rays that can be received by the receiver of the second measuring assembly 8. Even if the second intermediate bearing 6 is offset relative to the first intermediate bearing 5, the receiver of the second measuring assembly 8 can still receive the ultra-thin infrared rays emitted by sub-transmitter 22 of the first measuring assembly 7 and detect the offset L2 of the ultra-thin infrared rays. Furthermore, the second measuring assembly 8 includes a sub-sensor 23, which can sense the offset angle R2 of the second intermediate bearing 6.

[0034] The number of on-site measurement components 2 is not limited and can be set as needed. Generally, the more intermediate bearings there are, the more on-site measurement components 2 there are.

[0035] In one embodiment, see Figure 3 The reference measurement assembly 1 also includes a first housing 13 and first flanges 14 located on the left and right sides of the first housing 13. The reference measurement assembly 1 can be mounted on a vessel using screws via the two first flanges 14. The first housing 13 defines a first light outlet 131. The main sensor 11 and the main emitter 12 are both located within the first housing 13. The transmitting end of the main emitter 11 is located at the first light outlet 131, allowing the extremely fine infrared rays emitted by the main emitter 11 to be emitted through the first light outlet 131.

[0036] In one embodiment, see Figure 4 The on-site measurement component 2 also includes a second housing 24 and second flanges 25 located on the left and right sides of the second housing 24. The on-site measurement component 2 can be fixed to the ship using screws via the two second flanges 25. The second housing 24 is provided with a second light outlet 26 and a third light outlet 27 that are oppositely disposed. The sub-sensor 23, the receiver 21, and the sub-transmitter 22 are all located inside the second housing 24. The receiving end of the receiver 21 is located at the second light outlet 26 to receive the extremely fine infrared light emitted by the sub-transmitter 22 of the previous on-site measurement component 2. The transmitting end of the sub-transmitter 22 is located at the third light outlet 27 to allow the sub-transmitter 22 to emit the extremely fine infrared light through the third light outlet 27 and illuminate the receiver 21 of the next on-site measurement component 2.

[0037] In one embodiment, see Figure 2 The on-site measurement assembly 2 further includes a first motor 30, a bracket 28, and a rotating drum 29, which are disposed within the second housing 24. The bracket 28 is connected to the rotating drum 29. The receiver 21 and the sub-transmitter 22 are disposed at both ends of the rotating drum 29. The first motor 30 rotates the bracket 28 and can drive the bracket 28 to rotate in a first direction to adjust the directions of the receiver 21 and the sub-transmitter 22. The receiving end of the receiver 21 is aligned with the second light outlet 26 to receive the extremely fine infrared light emitted by the sub-transmitter 22 of the previous on-site measurement assembly 2. The transmitting end of the sub-transmitter 22 is aligned with the third light outlet 27 to allow the sub-transmitter 22 to transmit the extremely fine infrared light through the third light outlet 27 and illuminate the receiver 21 of the next on-site measurement assembly 2.

[0038] In one embodiment, see Figure 2 The in-situ measurement assembly 2 also includes a second motor 31 mounted on the bracket 28. The bracket 28 is rotatably connected to the rotating drum 29. The second motor 31 is connected to the rotating drum 29 and is capable of driving the rotating drum 29 to rotate in a second direction, which is perpendicular to the first direction. In this embodiment, the provision of the second motor 31 further expands the range of motion of the receiver 21 and the sub-transmitter 22, enabling the receiver 21 and the sub-transmitter 22 to more conveniently receive and transmit ultra-fine infrared rays.

[0039] In one embodiment, see Figure 2 The in-situ measurement assembly 2 further includes a controller 32, which is located at the bottom of the second housing 24. The first motor 30 is located within the controller 32, and the controller 32 is connected to the first motor 30, the second motor 31, the receiver 21, and the sub-transmitter 22. In this embodiment, the controller 32 is connected to a terminal device, so that the terminal device can operate the controller 32 to control the operation of the first motor 30 and the second motor 31, drive the rotating drum 29 in the first direction and / or the second direction, and adjust the direction of the receiver 21 and the sub-transmitter 22. The terminal device can also control the operation or non-operation of the receiver 21 and the sub-transmitter 22 through the controller 32.

[0040] In one embodiment, see Figure 2 Receiver 21 is a CCD four-quadrant photodetector. When a very fine infrared light spot impinges on the detector, the CCD four-quadrant photodetector locates the center of the very fine infrared light through the output currents of the four quadrants. Specifically, when the very fine infrared light spot is incident on the four-quadrant detector, the four quadrants output different photocurrents IA, IB, IC, and ID. By calculating these currents, the offset of the very fine infrared light spot can be determined, thereby locating the center of the spot. This type of detector is particularly important in space laser communication systems because it requires an acquisition, targeting, and tracking (APT) system to ensure precise alignment and stable tracking between the two communicating ends.

[0041] In addition, the CCD four-quadrant photodetector has the characteristics of high signal-to-noise ratio, high sensitivity, and high precision in performance. It also has the advantages of large dynamic range, small photoelectric crosstalk, high integration, small size, strong overload resistance, and stable and reliable performance.

[0042] In one embodiment, see Figure 2 The data acquisition and processing component 3 includes a data collector, a processor, and a display. The data collector is connected to the reference measurement component 1 and the local measurement component 2 and is used to collect the ultra-fine infrared light spot information measured by the reference measurement component 1 and the local measurement component 2. The processor is connected to the data collector and the display. The processor receives the light spot information collected by the data collector and processes it into visual information, which is transmitted to the display. The display shows the specific angular and positional offsets of the ship's intermediate bearing. By viewing the data displayed on the display, personnel can set the ship's maneuvering plan in advance to prevent further displacement of the intermediate bearing.

[0043] In a second aspect, the present invention further discloses a vessel comprising a hull, a drive motor, an output shaft, multiple intermediate bearings, and the aforementioned vessel output shaft intermediate bearing displacement monitoring device. The output shaft is disposed along the length of the hull, and the drive motor is connected to the output shaft and configured to drive the output shaft to rotate, thereby providing power for the vessel's navigation. The multiple intermediate bearings are spaced apart along the length of the output shaft and are all fixed to the hull so as to support the output shaft and enable normal rotation. Multiple in-situ measurement assemblies are provided, one for each of the intermediate bearings. A reference measurement assembly is provided adjacent to the output shaft, and the infrared emission direction of the reference measurement assembly is substantially parallel to the axis of the output shaft. When the hull experiences significant deformation due to varying degrees of ballast or strong winds, the hull causes one or more intermediate bearings to shift. The extremely fine infrared rays emitted and received by the multiple in-situ measurement assemblies provided on the intermediate bearings can be used to measure the corresponding intermediate bearing's displacement angle and distance, thereby inferring the extent of the intermediate bearing displacement and enabling a reasonable ship maneuvering plan to be formulated in advance to minimize intermediate bearing displacement.

[0044] In one embodiment, due to the functional configuration of the ship, the ship also includes a bulkhead 10, and the output shaft 4 is relatively long. In order not to affect the normal use of the output shaft 4, the output shaft can only be passed through the bulkhead 10. On-site measurement components 2 are provided on opposite sides of the bulkhead 10. The two on-site measurement components 2 can cooperate with other on-site measurement components 2 or the reference measurement component 1 to feedback the offset angle and offset distance of the intermediate bearing.

[0045] In order to better understand the present invention, the following Figures 1 to 4 The technical solution of the present invention is described in detail:

[0046] The device for monitoring the displacement of the intermediate bearing of the output shaft of a ship provided by the present invention can be installed on a ship for use. The reference measurement component is arranged near the output shaft, and multiple on-site measurement components can be installed one by one on multiple intermediate bearings. The reference measurement component and the multiple on-site measurement components are installed along the length direction of the output shaft so that the infrared rays emitted by the main transmitter of the reference measurement component can be received by the receiver of the on-site measurement component, and the infrared rays emitted by the auxiliary transmitter can be received by the receiver of the next on-site measurement component, so as to form a line of signal conduction. When the intermediate bearing is displaced, the offset angle can be obtained by the angle difference measured by adjacent sensors, and the deformation offset can be measured by the offset of the infrared rays sent and received by adjacent transmitters and receivers. The obtained offset angle and offset of the intermediate bearing can provide data reference for ship operation, and a reasonable ship operation plan can be set in advance to avoid easy damage to the intermediate bearing.
