Description

Technical Field

[0001] The present invention relates to the technical field of ship energy-saving device monitoring, and in particular to a high-efficiency energy-saving device circulation detection device for oil tankers and a method thereof. Background Art

[0002] As the global shipping industry continues to expand, ships have become a core means of transport for international trade. However, the enormous amount of fuel consumed by ships during navigation not only drives up operating costs but also exacerbates the climate change crisis through the emission of pollutants such as carbon dioxide. Against this backdrop, wind energy, due to its clean and renewable nature, has become a leading alternative energy source for ships.

[0003] Tankers use highly efficient energy-saving devices (such as guide stators and rotor wind tubes) to significantly reduce fuel consumption by optimizing propulsion efficiency or directly converting wind energy. Rotor sails, a representative technology for wind-assisted propulsion, operate based on the Magnus effect: a rotating cylinder generates a pressure difference in crosswinds, creating thrust perpendicular to the wind direction, providing additional propulsion power for the ship.

[0004] However, existing detection methods for rotor sails in actual operation have inherent limitations: First, there is a high reliance on manual labor. More than 80% of the equipment relies on visual inspections and regular docking inspections, resulting in long fault response delays and a lack of real-time tracking and detection of the cylinder structure deformation and surface conditions. Due to the structural characteristics of the cylinder's plastic deformation, strong wind loads at sea can easily cause the cylinder to bend and deform, destroying aerodynamic symmetry and thrust attenuation, making manual detection difficult. Secondly, the cylinder surface is covered with ice or corroded. The high humidity and salt spray environment causes ice to form on the cylinder or the coating to peel off, which doubles the rotation resistance and increases energy consumption. Visual inspection is restricted by weather conditions. In addition, the rotor sail device is huge, and the device is huge and traditional single-point sensors (such as thermometers) cannot fully detect it. The data is inaccurate, there are blind spots in the hidden state, and there is a lack of real-time monitoring methods for key parameters such as the external stress distribution and changes of the cylinder.

[0005] Therefore, it is urgent to develop a cycle detection system that combines real-time, accurate and comprehensive optimization capabilities. This will become the core breakthrough to ensure the continuous and efficient operation of the rotor duct. Summary of the Invention

[0006] The purpose of the present invention is to provide a high-efficiency energy-saving device circulation detection device for oil tankers and a method thereof, which realizes full coverage detection and cleaning of the cylinder surface through a composite motion trajectory of spiral lifting and rotating at the same time, solves the technical defects of blind spots in traditional detection devices, and at the same time utilizes the cylinder's own rotational power to drive, meeting the core design goal of "high efficiency and energy saving" and forming a closed loop of technical effects.

[0007] To achieve the above-mentioned object, the present invention provides the following technical solution: a high-efficiency energy-saving device circulation detection device for oil tankers, comprising a cylinder, a drive system and a support base, wherein the cylinder is arranged on the support base, and the drive system is arranged inside the cylinder for driving the cylinder to rotate; a cylinder state monitoring component is arranged outside the cylinder, including: A circulating drive mechanism is provided above the support base, comprising a driven gear ring rotatably connected to the top of the support base, an axial guide rail assembly, a first drive mechanism driving the driven gear ring to move, and a second drive mechanism driving the axial guide rail assembly to move; The annular support frame is sleeved on the outside of the cylinder and connected to the driven gear ring through the axial guide rail assembly; The annular support frame is driven by the first driving mechanism to rotate along the axial direction of the cylinder, and is driven by the second driving mechanism to reciprocate up and down along the axial direction of the cylinder; The deformation detection mechanism is connected to the annular support frame and includes an array of laser displacement sensors uniformly distributed around the circumference for scanning the curvature of the cylinder surface; The surface cleaning mechanism is connected to the annular support frame and includes an ice scraper and a sponge brush for removing ice or dirt from the surface of the cylinder.

[0008] Furthermore, the axial guide rail assembly includes: Two ball spline screws are symmetrically and parallelly arranged along the axis of the cylinder, and a threaded sleeve and a spline sleeve are sleeved on the outside of each ball spline screw. The top of the threaded sleeve is rotatably connected to the bottom end of the spline sleeve through a bearing, and the annular support frame is connected to the side of the spline sleeve; the bottom ends of the two ball spline screws are rotatably connected to the side of the driven gear ring, and the top ends of the two ball spline screws are provided with a cross bar, and the top ends of the two ball spline screws are each rotatably connected to one end of the cross bar.

[0009] Furthermore, the ball spline screw is provided with a thread groove cooperating with the threaded sleeve and a vertical spline groove cooperating with the spline sleeve, and the thread grooves arranged on the two ball spline screws rotate in opposite directions.

[0010] Furthermore, the first driving mechanism includes: a rotating gear meshing with the internal gear on the inner side of the driven gear ring, and the rotating gear is simultaneously meshing with the external gear on the outer side of the bottom end of the cylinder. The rotating gear is rotatably arranged above the support base and is provided with several.

[0011] When the cylinder is rotated by the driving system, the planetary gears are composed of the internal gear on the inner side of the driven gear ring, the rotating gear, and the external gear on the outer side of the bottom end of the cylinder, which synchronously drive the driven gear ring and the axial guide rail assembly and annular support frame on it to rotate around the axis of the cylinder. The rotation speed can be adjusted by the planetary gears.

[0012] Furthermore, the second driving mechanism includes: a driving gear coaxially arranged on the outside of the bottom end of the cylinder, the driving gear is semicircular, and a fixed gear is fixedly connected to the outside of the bottom end of the ball spline screw, and the driving gear is meshed with the fixed gear.

[0013] The driven gear ring and the axial guide rail assembly drive the synchronization of the first drive mechanism and the second drive mechanism, and at the same time drive the axis of the annular support frame cylinder to rotate, while synchronously making vertical movements up and down with the axis of the cylinder, forming a comprehensive cyclic detection of all directions on the outside of the cylinder.

[0014] Furthermore, the deformation detection mechanism is symmetrically and detachably arranged above the annular support frame, and each group of the laser displacement sensor array is composed of 4 groups of line laser sensors evenly spaced apart.

[0015] Furthermore, the surface cleaning mechanism includes: The shell has rotating rods symmetrically provided on both sides of the middle part of the inner cavity of the shell, and a rotating block is rotatably provided on the outer side of the rotating rod, one end of the rotating block is rotatably connected to one end of the connecting rod, and the other end of the rotating block is rotatably connected to one end of the first push rod, and one end of the first push rod is connected to an ice scraper corresponding to the shape of the cylinder surface; one end of the second push rod is symmetrically provided above both ends of the connecting rod, and the other end of the second push rod passes through the shell and is connected to a sponge brush, and one end of a compression spring is symmetrically provided at both ends of the connecting rod, and the other end of the compression spring is connected to the bottom of the inner cavity of the shell.

[0016] Through mechanical linkage, adaptive floating cleaning of the ice scraper and sponge brush is achieved, which adapts to the changes in the curvature of the cylinder surface and controls the cleaning pressure; during continuous movement, the spring deformation is adjusted in real time with the surface fluctuations, so that the ice scraper and sponge brush always contact the surface with optimal pressure; the ice scraper is self-adaptive in displacement through the lever mechanism rotating block + the first push rod to cope with the impact of protrusions; the maximum deformation of the compression spring limits the upper pressure limit of the cleaning component to avoid scratching the anti-corrosion coating of the cylinder, and is used to form a flexible cleaning for the outer surface of the cylinder.

[0017] Furthermore, a cover plate is provided above the driving gear.

[0018] A method for using a circulation detection device for a high-efficiency energy-saving device for an oil tanker comprises the following steps: starting a drive system to rotate a cylinder; synchronously activating a first drive mechanism and a second drive mechanism; The first drive mechanism drives the driven gear ring to rotate, driving the annular support frame and the deformation detection mechanism to rotate synchronously around the axis of the cylinder. At the same time, the semicircular driving gear of the second drive mechanism alternately engages the fixed gears on both sides, driving the two ball spline screws with opposite thread grooves to rotate alternately, causing the annular support frame to perform up and down cyclic reciprocating motion along the axial guide rail assembly. The laser displacement sensor array scans the curvature of the cylinder surface under the composite trajectory of rotation and reciprocating motion. When the deformation detection mechanism identifies ice or dirt on the surface, the surface cleaning mechanism is activated: the ice scraper is close to the surface of the cylinder to remove hard foreign objects through the lever mechanism of the first push rod and the rotating block; the sponge brush adjusts the pressure through the compression spring to flexibly clean the residual dirt; during the cleaning process, the annular support frame continues to move in a compound manner to achieve full coverage of the cylinder.

[0019] Compared with the prior art, the present invention has the following beneficial effects: Through the collaborative innovation of an integrated composite motion mechanism, an adaptive cleaning system, and a full-area scanning detection unit, this invention solves three core problems during the operation of the rotor sail: the difficulty in tracking structural deformation, the difficulty in removing surface ice and corrosion, and the low efficiency of manual inspection. Specifically, the following are embodied: 1. High-precision deformation monitoring with full coverage: Adopting planetary gear drive, the compound motion design of the second drive mechanism is linked by the first drive mechanism, semicircular gear and reverse screw: When the cylinder rotates, the planetary gear system composed of external gears, rotating gears and internal gears drives the annular support frame to revolve around the axis of the cylinder; synchronously, the semicircular driving gears alternately engage the fixed gears on both sides, driving the ball spline screws with opposite thread grooves to rotate alternately, so that the annular support frame can reciprocate along the axial direction; the laser displacement sensor array scans the surface of the cylinder under the spiral trajectory of revolution + axial motion to achieve full surface area coverage, generate high-precision curvature topology maps in real time, accurately identify plastic deformation, and eliminate human visual blind spots.

[0020] 2. Energy-saving and efficient driving mechanism: The present invention innovatively utilizes the rotational kinetic energy of the cylinder itself to drive the detection frame: the first driving mechanism converts the rotation of the cylinder into the revolution of the annular support frame through planetary gears, without the need for an additional rotary motor; the second driving mechanism converts the rotational motion into axial reciprocating motion through the alternating engagement of semicircular driving gears and reverse threaded screws, eliminating the need for an independent linear drive source and reducing energy consumption. It is particularly suitable for long-term operation of ship energy-saving devices.

[0021] 3. Adaptive cleaning and damage protection: The present invention achieves a dynamic balance between hard removal and soft cleaning through a mechanical linkage system via a surface cleaning mechanism: When the ice scraper encounters a hard object, the reverse force pushes the first push rod, causing the rotating block to rotate around the rod. The compression spring cushions the impact and prevents scratches on the cylinder's anti-corrosion coating. When the connecting rod is pressed down, the second push rod increases the brush pressure to intensify the removal of residual dirt. Once the foreign object is removed, the compression spring returns to the preset pressure. This overcomes the challenges of ice buildup and corrosion in high-salt fog environments, improves cleaning efficiency, and reduces coating damage.

[0022] After the deformation detection mechanism identifies surface abnormalities, it immediately triggers the cleaning unit mounted on the same frame, and synchronously performs scanning and cleaning under the continuous compound motion of the annular support frame, realizing a "monitoring-processing" closed loop.

[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figures 1-6, an embodiment provided by the present invention: A high-efficiency energy-saving device circulation detection device for oil tankers, comprising a cylinder 1, a drive system and a support base 2. The cylinder 1 is arranged on the support base 2 and is the main structure for generating thrust. The drive system is arranged inside the cylinder 1 and is used to drive the cylinder 1 to rotate. The cylinder 1 is provided with a cylinder 1 status monitoring component on the outside, including: The circulating drive mechanism 3 is provided above the support base 2 and includes a driven gear ring 31 rotatably connected to the top of the support base 2, an axial guide rail assembly 32, a first drive mechanism 33 that drives the driven gear ring 31 to move, and a second drive mechanism 34 that drives the axial guide rail assembly 32 to move; The annular support frame 4 is sleeved on the outside of the cylinder 1 and connected to the driven gear ring 31 through the axial guide rail assembly 32; The annular support frame 4 is driven by the first driving mechanism 33 to rotate along the axial direction of the cylinder 1, and is driven by the second driving mechanism 34 to reciprocate up and down along the axial direction of the cylinder 1; In this embodiment, the annular support frame 4 and the deformation detection mechanism 5 and surface cleaning mechanism 6 carried by it are completely decoupled from the cylinder 1, avoiding the influence of additional mass or mechanical resistance on the aerodynamic performance and rotational balance of the cylinder 1; the inner diameter of the frame is customized according to the outer diameter of the cylinder 1, and can be quickly disassembled and assembled to the existing rotor sail without changing the main structure of the cylinder 1; in addition, the independent support structure isolates the high-frequency vibration of the cylinder 1 to ensure the detection accuracy of the sensor and the stability of the cleaning mechanism.

[0027] The deformation detection mechanism 5 is connected to the annular support frame 4 and includes a circumferentially evenly distributed laser displacement sensor array for scanning the surface curvature of the cylinder 1; the deformation detection mechanism 5 is symmetrically arranged above the annular support frame 4 and adopts a detachable connection. In this embodiment, it is connected to the annular support frame 4 by bolts. Each group of the laser displacement sensor array is composed of 4 groups of evenly spaced line laser sensors 51.

[0028] In this embodiment, four groups of line laser sensors 51 on each side are used for multi-angle synchronous scanning: multiple groups of sensors synchronously emit high-density line lasers to form a continuous light band on the surface of the cylinder 1; by receiving the phase offset of the reflected laser, the distance from the sensor to the surface of the cylinder 1 is calculated in real time, and the surface curvature point cloud data is generated in combination with the circumferential position of the sensor and the axial motion trajectory of the frame; the point cloud data is fitted into a three-dimensional model of the cylinder 1, and compared with the baseline curvature map, local depressions, protrusions or bending deformations are automatically identified. The prior art is only introduced in principle here without further elaboration.

[0029] The surface cleaning mechanism 6 is connected to the annular support frame 4 and includes an ice scraper 68 and a sponge brush 69 for removing ice or dirt from the surface of the cylinder 1 .

[0030] The present invention uses an independent annular frame to physically isolate the detection system from the operation of the cylinder 1. The laser sensor array achieves full surface coverage through spiral trajectory scanning (revolution + axial movement), completing deformation monitoring and dirt removal without affecting the aerodynamic performance of the cylinder 1, solving the structural interference and coverage blind spot problems of traditional detection methods.

[0031] In this embodiment, the axial guide rail assembly 32 preferably includes: Two ball spline screws 321 are symmetrically and parallelly arranged along the axis of the cylinder 1. A threaded sleeve 322 and a spline sleeve 323 are sleeved on the outside of each ball spline screw 321. The top of the threaded sleeve 322 is rotatably connected to the bottom end of the spline sleeve 323 through a bearing 324, and the annular support frame 4 is connected to the side of the spline sleeve 323; the bottom ends of the two ball spline screws 321 are rotatably connected to the side of the driven gear ring 31, and the top ends of the two ball spline screws 321 are provided with a cross bar 325, and the top ends of the two ball spline screws 321 are each rotatably connected to one end of the cross bar 325.

[0032] The ball spline screw 321 is provided with a thread groove that cooperates with the threaded sleeve 322 and a vertical spline groove that cooperates with the spline sleeve 323. The thread grooves provided on the two ball spline screws 321 rotate in opposite directions.

[0033] The ball spline screw 321 integrates the thread groove and the vertical spline groove, which has high transmission efficiency and ensures that the axial motion accuracy error is within the controllable range; In this embodiment, the first driving mechanism 33 preferably includes: a rotating gear 332 meshing with an internal gear 331 on the inner side of the driven gear ring 31, and the rotating gear 332 is also meshing with an external gear 333 on the outer side of the bottom end of the cylinder 1. The rotating gear 332 is rotatably arranged above the support base 2 and is provided with a plurality of. The specific working principle of the first driving mechanism 33 in this embodiment is as follows: When the cylinder 1 is rotated by the driving system, the planetary gear is composed of the internal gear 331 inside the driven gear ring 31, the rotating gear 332, and the external gear 333 outside the bottom end of the cylinder 1, which synchronously drives the driven gear ring 31 and the axial guide rail assembly 32 and the annular support frame 4 thereon to rotate around the axis of the cylinder 1. The transmission ratio of the planetary gear is adjustable to adapt to different rotation speeds of the cylinder 1.

[0034] In this embodiment, the second drive mechanism 34 preferably includes: a driving gear 341 coaxially arranged on the outer side of the bottom end of the cylinder 1, the driving gear 341 being semicircular in shape, and a fixed gear 342 fixedly connected to the outer side of the bottom end of the ball spline screw 321, the driving gear 341 meshing with the fixed gear 342. A cover plate 343 is provided above the driving gear 341 to prevent dust and jamming, ensuring stable operation under harsh working conditions at sea. The specific working principle of the second drive mechanism 34 in this embodiment is as follows: When the cylinder 1 rotates, the driving gear 341 is synchronously driven to rotate, and the fixed gear 342 is driven to rotate, and the ball spline screw 321 is rotated. Since the driving gear 341 is semicircular, it can only contact and rotate with the ball spline screw 321 on one side. When the ball spline screw 321 on one side rotates, since its two ends are rotatably connected, the rotational motion of the ball spline screw 321 drives the threaded sleeve 322 to cooperate with the thread groove to make a linear motion upward, and at the same time drives the spline sleeve 323 and the annular support frame 4 to move. At this time, the ball spline screw 321 on the other side rotates but does not rotate, and the ball spline screw 321 on it does not rotate. The spline sleeve 323 is driven by the annular support frame 4 to perform linear motion, and drives the threaded sleeve 322 rotatably connected to it below to perform rotational motion; when the driving gear 341 completes a semicircular rotation and contacts the ball spline screw 321 on the other side and drives it to rotate, since the thread grooves on the two ball spline screws 321 rotate in opposite directions, the two threaded sleeves 322 also perform linear motion with opposite strokes. When the threaded sleeve 322 on one side drives the annular support frame 4 to move to the top end, it is converted to the threaded sleeve 322 on the other side to drive the annular support frame 4 back to the bottom end, forming a cyclic reciprocating motion.

[0035] The driven gear ring 31 and the axial guide rail assembly 32 drive the first drive mechanism 33 and the second drive mechanism 34 synchronously, and at the same time, the annular support frame 4 drives the cylinder 1 to rotate axially, and synchronously makes vertical movements up and down with the axis of the cylinder 1, forming a comprehensive cyclic detection of all directions of the outside of the cylinder 1.

[0036] In this embodiment, the surface cleaning mechanism 6 preferably includes: Shell 61, the top of the shell 61 is connected to the bottom of the annular support frame 4, and a detachable connection is adopted. In this embodiment, it is connected to the bottom surface of the annular support frame 4 by bolts; rotating rods 62 are symmetrically provided on both sides of the middle part of the inner cavity of the shell 61, and a rotating block 63 is rotatably provided on the outer side of the rotating rod 62. One end of the rotating block 63 is rotatably connected to one end of the connecting rod 64, and the other end of the rotating block 63 is rotatably connected to one end of the first push rod 65, and one end of the first push rod 65 is connected to an ice scraper 68 corresponding to the surface shape of the cylinder 1; one end of a second push rod 66 is symmetrically provided above both ends of the connecting rod 64, and the other end of the second push rod 66 passes through the shell 61 and is connected to a sponge brush 69, and one end of a compression spring 67 is symmetrically provided at both ends of the connecting rod 64, and the other end of the compression spring 67 is connected to the bottom of the inner cavity of the shell 61.

[0037] The mechanical linkage enables the adaptive floating cleaning of the ice scraper 68 and the sponge brush 69, adapting to the curvature change of the cylinder 1 surface and controlling the cleaning pressure. The specific working principle of the surface cleaning mechanism 6 in this embodiment is as follows: In the initial state, the surface cleaning mechanism 6 contacts the surface of the cylinder 1: Positioning of the ice scraper 68 : The ice scraper 68 , which matches the surface shape of the cylinder 1 , is pressed against the cylinder 1 through the first push rod 65 .

[0038] Pre-compression of the sponge brush 69: The sponge brush 69 contacts the surface of the cylinder 1 under the initial pre-compression of the compression spring 67.

[0039] When the ice scraper 68 encounters ice or hard foreign objects such as protrusions to be removed: The ice scraper 68 is subjected to a reverse force, pushing the first push rod 65 to move toward the inside of the housing 61. The first push rod 65 drives the rotating block 63 to rotate around the rotating rod 62, and the rotating block 63 drives the connecting rod 64 to move downward, so that the ice scraper 68 can maintain contact while buffering the impact force, thereby preventing hard scraping and damaging the cylinder 1. The flexible cleaning sponge brush 69 moves: the connecting rod 64 moves downward synchronously, and the symmetrically arranged second push rod 66 is lifted up synchronously, and the pressure of the sponge brush 69 on the surface of the cylinder 1 is increased, and the brush is used to assist in cleaning and wiping when the ice scraper 68 removes hard objects.

[0040] Reset after foreign matter is removed: the compression spring 67 is retracted, pushing the connecting rod 64 upward, and the second push rod 66 retracts the sponge brush 69 to restore the preset cleaning pressure.

[0041] During continuous motion, the spring's deformation adjusts in real time with surface fluctuations, ensuring that the ice scraper 68 and sponge brush 69 maintain optimal contact pressure. The ice scraper 68 utilizes a lever mechanism, rotating block 63, and first push rod 65 to achieve adaptive displacement, counteracting impacts from bumps. The sponge brush 69 achieves adaptive pressure through a spring system, maintaining consistent cleaning results. The maximum deformation of the compression spring 67 limits the upper pressure limit of the cleaning components, preventing scratches on the anti-corrosion coating of the cylinder 1 and ensuring flexible cleaning of the cylinder 1's exterior surface.

[0042] A method for using a high-efficiency energy-saving device circulation detection device for oil tankers comprises the following steps: starting a drive system to rotate a cylinder 1; synchronously activating a first drive mechanism 33 and a second drive mechanism 34; The driven gear ring 31 is driven to rotate by the first driving mechanism 33, driving the annular support frame 4 and the deformation detection mechanism 5 to rotate synchronously around the axis of the cylinder 1. At the same time, the semicircular driving gear 341 of the second driving mechanism 34 alternately engages the fixed gears 342 on both sides, driving the two ball spline screws 321 with opposite thread grooves to rotate alternately, causing the annular support frame 4 to perform an up and down reciprocating motion along the axial guide rail assembly 32. The laser displacement sensor array scans the surface curvature of the cylinder 1 under the composite trajectory of rotation and reciprocating motion. When the deformation detection mechanism 5 identifies ice or dirt on the surface, the surface cleaning mechanism 6 is activated: the ice scraper 68 is close to the surface of the cylinder 1 to remove hard foreign objects through the lever mechanism of the first push rod 65 and the rotating block 63; the sponge brush 69 adjusts the pressure through the compression spring 67 to flexibly clean the residual dirt; during the cleaning process, the annular support frame 4 continues to move in a compound manner to achieve full coverage of the cylinder 1.

[0043] The present invention realizes full coverage detection and cleaning of the cylinder surface through a composite motion trajectory of spiral lifting and rotating at the same time, solving the technical defect of blind spots in traditional detection devices. At the same time, it utilizes the rotational power of the cylinder itself to drive, meeting the core design goal of "high efficiency and energy saving", and forming a closed loop of technical effects.
