Description

Technical Field

[0001] The present invention relates to the technical field of production detection of diesel generator sets, and more particularly to a production detection system and a detection method thereof. Background Art

[0002] As a commonly used emergency power supply equipment, diesel generator sets are usually composed of diesel engines, generators, control systems and related auxiliary components. The diesel engine drives the generator to operate to achieve power output. They are widely used in scenarios with high requirements for continuous power supply, such as ships, data centers, and hospitals.

[0003] In the existing technology, the inspection of such units is often carried out by placing them on a test bench by hoisting. After being positioned with bolts, the vibration resistance of the test bench is tested by horizontal displacement vibration. However, this inspection method can only realize a single horizontal vibration test and cannot simulate the impact of the hull swing on the diesel generator set. For this reason, the staff improved the existing method and set the test bench as a comprehensive vibration platform, that is, the test bench can not only perform horizontal displacement vibration, but also swing, simulating the swing force existing when the diesel generator set is installed on the ship, and testing whether the diesel generator set can be used normally in harsh environments.

[0004] However, in the existing inspection process, although the diesel generator set has achieved horizontal vibration and swing testing, when faced with complex environmental scenarios such as the centrifugal force of the hull turning and the coupling of complex working conditions, the existing inspection dimensions still have insufficient coverage, making it difficult to fully verify the operating reliability of the unit in actual complex environments. It is necessary to further expand the inspection conditions to improve the comprehensiveness of the test. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the present invention aims to provide a production detection system and a detection method for a diesel generator set.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a diesel generator set production detection system, comprising a frame, a simulation component installed inside the frame, and an offset component installed on the top of the simulation component, multiple groups of buffer components are installed around the top of the offset component, generator sets are arranged between the multiple groups of buffer components, a locking component is installed on the top of each group of buffer components, and four groups of connecting components are installed around the top of the offset component.

[0007] The simulation component includes a fixing seat installed inside the frame and a plurality of telescopic cylinders hinged to the top of the fixing seat. The tops of the plurality of telescopic cylinders are hinged to a supporting seat, and a fixing plate is installed on the top of the supporting seat.

[0008] The offset assembly includes a turntable rotating on the top of the fixed plate, an electric slide rail installed on the top of the turntable and a placement seat slidably connected to the top of the electric slide rail. The buffer assembly, connection assembly and generator set are all located above the placement seat.

[0009] The present invention is further configured as follows: a drive motor is installed vertically upward at the bottom of the support seat, the output end of the drive motor passes through the support seat and is connected to the bottom center of the turntable, two guide rails are symmetrically installed on the top of the turntable, the extension direction of the guide rails is consistent with the extension direction of the electric slide rail, and the top of the guide rails is slidably connected to two sliders, and both of the sliders are connected to the bottom of the placement seat.

[0010] By adopting the above technical solution, after the generator set completes the detection under displacement and swinging movements, the placement seat is driven by the electric slide to move horizontally for a certain distance, causing the placement seat and the generator set to move away from the rotation center of the turntable. Then, the drive motor drives the turntable, electric slide, placement seat and generator set to move centrifugally. The generator set continues to operate in this state for a preset time, thereby simulating the inertial load caused by changes in motion trajectory in the ship turning scenario, alleviating the current situation of insufficient detection dimension coverage in complex environments.

[0011] The present invention is further configured as follows: each group of the buffer components includes a buffer mechanism, the interior of the buffer mechanism is connected with a column, the top of the column passes through the generator set, and the outer side wall of the column is installed with a block ring.

[0012] The present invention is further configured as follows: the generator set includes a base and a set main body installed on the top of the base, a plurality of through holes are opened on the top of the base, the plurality of through holes are arranged corresponding to a plurality of columns, the columns are inserted into the corresponding through holes, and the bottom surface of the base is in contact with the top surface of the resistance ring.

[0013] The present invention is further configured as follows: each group of the locking assemblies includes a sleeve, a plurality of the sleeves are arranged corresponding to a plurality of columns, the bottom end of the sleeve is connected to the top of the corresponding column, and the top of the sleeve is connected to a circular plate.

[0014] The present invention is further configured as follows: two first hinged plates are symmetrically hinged on the top of the circular plate, the tops of the two first hinged plates are hinged with a second hinged plate, the tops of the second hinged plates are hinged with a pressure plate, and an adjusting cylinder is vertically installed inside the sleeve, and the piston rod of the adjusting cylinder passes through the corresponding circular plate and is connected to the bottom of the pressure plate.

[0015] The present invention is further configured such that the hinge points of the first hinge plate and the second hinge plate are both provided with guiding inclined surfaces, and the guiding inclined surfaces are extended in a direction away from the center line of the circular plate.

[0016] By adopting this technical solution, pre-positioning is achieved during the placement of the generator set through the use of lifting equipment in conjunction with locking and buffer assemblies. After the pressure plate passes through the base's retaining hole, the base continuously slides downward and fits over the outside of the column. The column's outer wall block ring fits against the base's bottom, ensuring precise initial placement. Multiple sets of locking assemblies extend upward to the side walls of the unit body, improving the generator set's stability during vibration and shaking.

[0017] After the generator set is positioned, the regulating cylinder contracts, driving the pressure plate to squeeze the hinge plate. The hinge plate then swings along the guiding slope, ensuring the hinge point fits snugly against the outer wall of the generator set body, achieving precise positioning. This structure effectively limits the overall swing amplitude of the generator set and mechanically prevents excessive tipping during operation, enhancing equipment stability, reducing safety risks and the probability of equipment damage caused by tipping, and ensuring safe operation.

[0018] The present invention is further configured such that: the four groups of connecting assemblies are all located at the four sides of the top surface of the placement seat, and the four groups of connecting assemblies each include a connecting seat mounted on the top of the placement seat, a servo motor is mounted on one side of the connecting seat, an output end of the servo motor passes through the corresponding connecting seat and is connected to a swing seat, and a support tube is mounted on one side of the swing seat;

[0019] Among them, multiple vertical pipes are installed on the top of the support tube located on the longer side of the top surface of the buffer mechanism, and one vertical pipe is installed on the top of the support tube located on the shorter side of the top surface of the buffer mechanism. The number of the vertical pipes is the same as that of the buffer assembly and they are arranged in a one-to-one correspondence. The top of each vertical pipe is slidably connected with a sliding rod, and a U-shaped frame is installed on the top of the sliding rod. The opening of the U-shaped frame is set toward one side of the generator set, and a micro cylinder is installed on one side of the U-shaped frame, and the piston rod of the micro cylinder extends to the inside of the U-shaped frame.

[0020] The present invention is further configured as follows: a gap is provided between the side wall of the sliding rod and the inner side wall of the vertical pipe; a limit block is installed at one end of the sliding rod close to the vertical pipe; a blocking plate is installed at one end of the connecting seat close to the sliding rod; the sliding rod passes through the blocking plate, and the limit block is adapted to the inner diameter of the vertical pipe.

[0021] The bottom of each limiting block is connected with a rope, the bottom of the outer side wall of the riser is provided with a through hole, one end of the rope passes through the through hole and is connected with the top of the placement seat.

[0022] By adopting the above technical solution, the servo motor is used to drive the various components to work together, so that the connecting component can be automatically installed and the locking structure of the generator set can be locked to form a stable connection. When the generator set shakes, the locking component and the connecting component pull each other, and the rope is used to limit the shaking amplitude, thereby improving the anti-dumping performance and further improving the anti-dumping effect, avoiding damage to the locking component when the generator set tips over. The automated connection process replaces manual operation, significantly improving connection efficiency and operational safety.

[0023] A diesel generator set production detection method, using a diesel generator set production detection system as described above, includes the following steps:

[0024] S1. The generator set is hoisted to the top of the placement seat by using a hoisting device, and is pre-positioned by using multiple sets of buffer assemblies and locking assemblies. Then the generator set is continued to be lowered by using the hoisting device until the generator set is positioned by using the buffer assemblies and locking assemblies.

[0025] S2. Then, the connecting component is connected and locked with the corresponding locking component.

[0026] S3. After the positioning of the generator set is completed, it starts to run. Then, the offset component, buffer component, generator set displacement vibration and surrounding swing are controlled by simulation components. The simulation components are used to test the vibration resistance of the generator set body. During the vibration process, the generator set uses the elastic deformation of the buffer component to simulate the elastic support working condition of the generator set in the actual application scenario, and absorbs and transmits vibration energy, adjusts the vibration frequency and amplitude during the test, so that the vibration load borne by the generator set during the test is closer to the actual operating environment. When the generator set is shaking, the connection component is used to cooperate to control the shaking amplitude of the generator set.

[0027] After completing the detection under S4, displacement and swinging motions, the generator set is moved horizontally for a certain distance through the offset component. Then, the offset component drives the generator set to perform centrifugal motion, thereby simulating the inertial load caused by the change in motion trajectory in the ship turning scenario.

[0028] S5. After the test is completed, the connecting assembly is separated from the locking assembly, and then the locking assembly cancels the positioning state of the generator set. Then, the generator set can be lifted and removed using the lifting equipment.

[0029] In summary, this application includes at least one of the following beneficial technical effects:

[0030] (1) After the generator set completes the detection under displacement and swinging motions, the placement seat is driven by the electric slide to move horizontally for a certain distance, causing the placement seat and the generator set to move away from the rotation center of the turntable. Then, the drive motor drives the turntable, electric slide, placement seat and generator set to move centrifugally. The generator set continues to operate in this state for a preset time, thereby simulating the inertial load caused by the change of motion trajectory in the ship turning scenario, alleviating the current situation of insufficient detection dimension coverage in complex environments.

[0031] (2) During the placement of the generator set, the pre-positioning function is achieved through the lifting equipment in conjunction with the locking assembly and the buffer assembly. After the pressure plate passes through the base limit hole, the base continues to move downward and is mounted on the outside of the column. The outer wall resistance ring of the column is fitted with the bottom of the base to ensure the accuracy of the initial placement position. In addition, multiple sets of locking assemblies are extended upward to the side wall of the unit body to improve the stability of the generator set during vibration and shaking.

[0032] (3) After the generator set is placed, the cylinder is adjusted to contract and drive the pressure plate to squeeze the hinge plate. The hinge plate swings using the guiding slope so that the hinge point fits tightly against the outer wall of the generator body, completing precise positioning. This structure effectively limits the overall swing amplitude of the generator set and prevents it from excessively tipping over during operation through mechanical limiters, thereby enhancing equipment stability, reducing safety risks and equipment damage probability caused by tipping, and ensuring safe operation.

[0033] (4) By setting up a connection component and using a servo motor to drive the various components to work together, the connection component can be automatically installed and locked to the locking structure of the generator set to form a stable connection. When the generator set shakes, the locking component and the connection component pull each other, and the rope is used to limit the shaking amplitude, thereby improving the anti-tipping performance and further improving the anti-tipping effect, avoiding damage to the locking component when the generator set tips over. The automated connection process replaces manual operation, significantly improving connection efficiency and operation safety. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0052] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0053] See also Figures 1-9 , the present invention provides the following technical solutions:

[0054] Embodiment 1, a diesel generator set production detection system, includes a frame 1, a simulation component 2 installed inside the frame 1, the simulation component 2 is used to simulate a complex environment, an offset component 3 installed on the top of the simulation component 2, multiple groups of buffer components 4 are installed around the top of the offset component 3, and generator sets 7 are arranged between the multiple groups of buffer components 4. The generator set 7 uses the multiple groups of buffer components 4 to assist in positioning and placement. After the generator set 7 is positioned and placed, the simulation component 2 is used to simulate a complex environment to test whether the generator set 7 can be used normally in a harsh environment.

[0055] The specific structure of simulation component 2 is as follows:

[0056] The simulation component 2 includes a fixed base 21 installed inside the frame 1 and a plurality of telescopic cylinders 22 hinged to the top of the fixed base 21. The tops of the plurality of telescopic cylinders 22 are hinged with a support base 23, and a fixed plate 24 is installed on the top of the support base 23. The telescopic cylinders 22 are hinged to the fixed base 21 and the support base 23 in a ball joint manner, and the telescopic cylinders 22 are used to drive the support base 23 to move up and down, that is, when one of the telescopic cylinders 22 is extended and retracted and the other telescopic cylinders 22 remain stationary, the support base 23 will tilt, and the fixed base 21 and the support base 23 are connected by six telescopic cylinders 22, and flexible rotation is achieved by using ball joints. Its working principle is to use the six telescopic cylinders 22 to cooperate with each other to control the compound motion of the support base 23 in six degrees of freedom, thereby simulating the vibration resistance of the generator set 7 in a complex environment.

[0057] Each set of buffer components 4 includes a buffer mechanism 41, and the buffer mechanism 41 is internally inserted and connected with a column 42. The top of the column 42 is set through the generator set 7, and the outer wall of the column 42 is installed with a resistance ring. The buffer mechanism 41 is a ball joint spring vibration damping seat, which is mainly composed of a ball joint assembly, a spring unit and a base. The column 42 extends to the inside of the base and is connected to the ball joint assembly, wherein the ball joint assembly realizes three-dimensional rotational freedom through spherical contact. The spring unit mostly adopts coil springs or disc springs and is evenly arranged radially. The base is used for fixed installation. The principle is to use the universal rotation characteristics of the ball joint to adapt to the multi-angle swing of the vibration-damped equipment. When the equipment is subjected to a vibration load, the ball joint allows it to produce angular displacement, and the spring buffers linear vibration by compression or tension.

[0058] The generator set 7 includes a base 71 and a unit body 72 installed on the top of the base 71. A plurality of through holes are opened on the top of the base 71. The plurality of through holes are arranged corresponding to the plurality of columns 42. The columns 42 are inserted into the corresponding through holes, and the bottom surface of the base 71 is in contact with the top surface of the resistance ring.

[0059] When the column 42 passes through the through hole of the base 71, the base 71 and the buffer assembly 4 form a whole. When the base 71 and the unit body 72 shake and vibrate, the column 42 in the buffer assembly 4 vibrates in multiple directions inside the buffer mechanism 41. The elastic deformation of the buffer assembly 4 is used to simulate the elastic support working condition of the generator set 7 in the actual application scenario, and absorb and transmit vibration energy, adjust the vibration frequency and amplitude during detection, so that the vibration load borne by the generator set 7 during detection is closer to the actual operating environment.

[0060] Specifically, before the vibration resistance test, the generator set 7 is first started and operated for a preset time. Then, the different telescopic lengths of multiple telescopic cylinders 22 are used to adjust the displacement and swing angle of the support seat 23 and the fixed plate 24. The displacement and swing of the fixed plate 24 drive the vibration displacement and swing of the offset component 3, multiple groups of buffer components 4 and the generator set 7, thereby testing the vibration resistance of the unit body 72 within the preset time.

[0061] When the generator set 7 is in operation, the vibration resistance test is performed to determine whether the vibration parameters such as amplitude, acceleration, frequency, etc. of the key parts of the unit are within the specified thresholds, whether there are abnormal noises, electrical faults, etc. during operation, and whether the structural components of the unit maintain integrity and are not loose or damaged. At the same time, its adaptability under different working conditions such as no-load and load is verified, so as to determine whether the generator set 7 passes the vibration resistance test.

[0062] Example 2: In the existing detection process, although the generator set 7 has achieved horizontal vibration and swing tests, when facing complex environmental scenarios such as the centrifugal force of the hull turning and the coupling of complex working conditions, the existing detection dimensions still have insufficient coverage, making it difficult to fully verify the operating reliability of the generator set 7 in the actual complex environment. It is necessary to further expand the detection conditions to improve the comprehensiveness of the test.

[0063] To this end, the installation position of the generator set 7 can be dynamically adjusted through the offset component 3. This operation can simulate the centrifugal force loading scenario when the hull turns, alleviating the current situation of insufficient detection dimension coverage in complex environments.

[0064] The offset assembly 3 includes a turntable 35 that rotates on the top of the fixed plate 24, an electric slide rail 36 installed on the top of the turntable 35, and a placement seat 31 that is slidably connected to the top of the electric slide rail 36. The buffer assembly 4 and the generator set 7 are both located above the placement seat 31. The electric slide rail 36 is used to drive the placement seat 31 to move. When moving, the placement seat 31 synchronously drives the buffer assembly 4 and the generator set 7 to move as a whole, thereby adjusting the position of the generator set 7, which is convenient for subsequent centrifugal testing of the generator set 7.

[0065] A drive motor 34 is installed vertically upward at the bottom of the support seat 23. The output end of the drive motor 34 passes through the support seat 23 and is connected to the bottom center of the turntable 35. Two guide rails 32 are symmetrically installed on the top of the turntable 35. The extension direction of the guide rail 32 is consistent with the extension direction of the electric slide rail 36. The top of the guide rail 32 is slidably connected to two sliders 33, and both sliders 33 are connected to the bottom of the placement seat 31. After the generator set 7 completes the detection under displacement and swinging actions, the electric slide rail 36 drives the placement seat 31 to move horizontally for a distance, causing the placement seat 31 and the generator set 7 to move away from the rotation center of the turntable 35. Then, the drive motor 34 drives the turntable 35, the electric slide rail 36, the placement seat 31 and the generator set 7 to move centrifugally. The generator set 7 continues to operate for a preset time in this state, thereby simulating the inertial load borne due to changes in motion trajectory in the ship steering scenario, alleviating the current situation of insufficient detection dimension coverage in complex environments.

[0066] In the third embodiment, in order to prevent the diesel generator set from being overloaded during the inspection process, which may easily cause it to overturn, the staff uses ropes to connect to the diesel generator set. When the diesel generator set over-tops, the ropes pull the diesel generator set. However, when installing the diesel generator set, the staff needs to manually connect the ropes, which is inefficient.

[0067] Therefore, a locking assembly 5 is installed on the top of each group of buffer assemblies 4. In the initial state, the locking assembly 5 does not affect the connection between the generator set 7 and the buffer assembly 4. When the generator set 7 and the buffer assembly 4 are positioned, the locking assembly 5 is used to limit the overall swing of the generator set 7 to prevent the generator set 7 from excessively tipping over.

[0068] Each locking assembly 5 includes a sleeve 51, and multiple sleeves 51 are arranged corresponding to multiple columns 42. The bottom end of the sleeve 51 is connected to the top of the corresponding column 42. The top of the sleeve 51 is connected to a circular plate 56. The top of the circular plate 56 is symmetrically hinged to two first hinge plates 52. The tops of the two first hinge plates 52 are hinged to a second hinge plate 53. The top of the second hinge plate 53 is hinged to a pressure plate 54. An adjusting cylinder 55 is vertically installed inside the sleeve 51. The piston rod of the adjusting cylinder 55 passes through the corresponding circular plate 56 and is connected to the bottom of the pressure plate 54. 55 is used to drive the pressure plate 54 to move up and down, squeezing or pulling the top end of the second hinge plate 53 during the movement. When the second hinge plate 53 swings, the first hinge plate 52 swings synchronously. Specifically, when the top end of the second hinge plate 53 moves downward, the first hinge plate 52 and the second hinge plate 53 are unfolded, and the hinge points of one group of the first hinge plate 52 and the second hinge plate 53 are in contact with the side wall of the unit body 72. Multiple groups of locking assemblies 5 cooperate to squeeze and position the side wall of the unit body 72 at multiple points, thereby assisting in positioning the generator set 7 and preventing the generator set 7 from excessively tipping over.

[0069] When the cam 71 is in the upright position, the locking cam 52 is in the upright position, and the locking cam 53 is in the upright position, so that the locking cam 53 ...

[0070] The hinge points of the first hinge plate 52 and the second hinge plate 53 are both provided with guiding slopes, which extend in a direction away from the center line of the circular plate 56. This arrangement can guide the tilting direction when the first hinge plate 52 and the second hinge plate 53 are hinged.

[0071] Four groups of connecting components 6 are installed around the top of the offset component 3. The connecting components 6 are located above the placement seat 31. The connecting components 6 are used to connect and lock with the corresponding locking components 5, which further improves the anti-dumping effect and avoids damage to the locking components 5 when the generator set 7 dumps. At the same time, the automatic connection function of the connecting components 6 is utilized to improve the connection efficiency without manual operation.

[0072] The four groups of connecting components 6 are all located on the four sides of the top surface of the placement seat 31, and the four groups of connecting components 6 include a connecting seat 61 installed on the top of the placement seat 31, and a servo motor 62 is installed on one side of the connecting seat 61. The output end of the servo motor 62 passes through the corresponding connecting seat 61 and is connected to a swing seat 63. A support tube 64 is installed on one side of the swing seat 63. The servo motor 62 is used to drive the swing seat 63 to swing, thereby adjusting the position of the support tube 64.

[0073] Among them, a plurality of vertical pipes 65 are installed on the top of the support tube 64 located at the longer side position of the top surface of the buffer mechanism 41, and a vertical pipe 65 is installed on the top of the support tube 64 located at the shorter side position of the top surface of the buffer mechanism 41. The number of vertical pipes 65 is the same as that of the buffer assembly 4 and they are arranged one by one. The top of each vertical pipe 65 is slidably connected with a sliding rod 66, and a U-shaped frame 68 is installed on the top of the sliding rod 66. The opening of the U-shaped frame 68 is set toward one side of the generator set 7. A micro cylinder 69 is installed on one side of the U-shaped frame 68. The piston rod of the micro cylinder 69 extends to the inside of the U-shaped frame 68, through By controlling the servo motor 62 to start, the servo motor 62 drives the corresponding swing seat 63 to swing, and the swing seat 63 drives the corresponding support tube 64 and the vertical tube 65 to swing, and the vertical tube 65 drives the sliding rod 66 and the U-shaped frame 68 to approach the position of the corresponding locking component 5, so that the U-shaped frame 68 is mounted on the hinge of one group of the first hinge plates 52 and the second hinge plates 53 on the corresponding group of locking components 5, and then the piston rod of the micro cylinder 69 is extended, so that the U-shaped frame 68 forms a locking ring, and the hinge of one group of the first hinge plates 52 and the second hinge plates 53 is locked in this locking ring.

[0074] There is a gap between the side wall of the sliding rod 66 and the inner wall of the standpipe 65. A limit block is installed at one end of the sliding rod 66 close to the standpipe 65. A blocking plate is installed at one end of the connecting seat 61 close to the sliding rod 66. The sliding rod 66 passes through the blocking plate, and the limit block is adapted to the inner diameter of the standpipe 65. A rope 601 is connected to the bottom of each limit block. A through hole 67 is provided at the bottom of the outer wall of the standpipe 65. One end of the rope 601 passes through the through hole 67 and is connected to the top of the placement seat 31. When the generator set 7 drives the column 42 and the The corresponding locking assembly 5 shakes synchronously. At this time, the corresponding locking assembly 5 pulls the corresponding U-shaped frame 68 and the micro cylinder 69. The U-shaped frame 68 drives the sliding rod 66 to slide inside the corresponding vertical pipe 65, and the rope 601 is pulled. When the shaking amplitude of the generator set 7 is too large, the rope 601 can control the shaking amplitude of the generator set 7, further improving the anti-dumping effect, and avoiding damage to the locking assembly 5 when the generator set 7 dumps. At the same time, the automatic connection function of the connecting assembly 6 is used to improve the connection efficiency without manual operation.

[0075] Example 4, a diesel generator set production detection method, using the above-mentioned diesel generator set production detection system, includes the following steps:

[0076] S1. Use a lifting device to lift the generator set 7 to the top of the placement seat 31, and pre-position it through multiple groups of buffer components 4 and locking components 5. Then, the generator set 7 continues to descend using the lifting equipment until the generator set 7 is completely positioned using the buffer components 4 and locking components 5.

[0077] The more specific steps of S1 are:

[0078] S11. Use lifting equipment to lift the generator set 7 to the top of the placement seat 31, and pre-position it through multiple sets of locking components 5 and buffer components 4, that is, the pressure plate 54 first passes through the limiting hole on the base 71, and then the base 71 continues to move downward, and the limiting hole passes through the first hinge plate 52, the second hinge plate 53, and the sleeve 51 in turn until it is sleeved on the outer wall of the column 42, and the resistance ring on the outer wall of the column 42 fits with the bottom of the base 71.

[0079] S12. After placement is completed, the piston rod of the control-adjusting cylinder 55 is controlled to retract, causing the pressure plate 54 to move downward to squeeze the second hinged plate 53. The second hinged plate 53 and the first hinged plate 52 are hinged and swung using the guiding inclined plane therebetween. A set of hinge points of the first hinged plate 52 and the second hinged plate 53 gradually fits onto the outer side wall of the unit body 72, thereby achieving the positioning of the unit body 72.

[0080] S2. Then, the connecting component 6 is connected and locked with the corresponding locking component 5.

[0081] The more specific steps of S2 are:

[0082] S21. Then, the servo motor 62 is controlled to start, and the servo motor 62 drives the corresponding swing seat 63 to swing. The swing seat 63 drives the corresponding support tube 64 and the vertical tube 65 to swing. The vertical tube 65 drives the sliding rod 66 and the U-shaped frame 68 to approach the position of the corresponding locking component 5, so that the U-shaped frame 68 is mounted on the hinge of one group of the first hinge plates 52 and the second hinge plates 53 on the corresponding group of locking components 5. Then, the piston rod of the micro cylinder 69 is extended, so that the U-shaped frame 68 forms a locking ring, and the hinge of one group of the first hinge plates 52 and the second hinge plates 53 is locked in this locking ring.

[0083] S3. After the positioning of the generator set 7 is completed, it starts to start running, and then the simulation component 2 is used to control the displacement vibration and surrounding swing of the offset component 3, the buffer component 4, and the generator set 7. The simulation component 2 is used to test the vibration resistance of the unit body 72. During the vibration process, the generator set 7 uses the elastic deformation of the buffer component 4 to simulate the elastic support working condition of the generator set 7 in the actual application scenario, and absorbs and transmits vibration energy, adjusts the vibration frequency and amplitude during the test, so that the vibration load borne by the generator set 7 during the test is closer to the actual operating environment. When the generator set 7 is shaking, the connection component 6 is used to cooperate to control the shaking amplitude of the generator set 7.

[0084] The more specific steps for S3 are:

[0085] S31. After the positioning of the generator set 7 is completed, it starts to run for a preset time, and then uses multiple telescopic cylinders 22 with different telescopic lengths to adjust the displacement and swing angle of the support seat 23 and the fixed plate 24. The displacement and swing of the fixed plate 24 drive the vibration displacement and swing of the offset component 3, multiple groups of buffer components 4 and the generator set 7, and then tests the vibration resistance of the unit body 72 within the preset time.

[0086] S32. During the vibration of the generator set 7, the base 71 will drive the vibration of the column 42 in the buffer mechanism 41, and use the elastic deformation of the buffer component 4 to simulate the elastic support working condition of the generator set 7 in the actual application scenario, and absorb and transmit vibration energy, adjust the vibration frequency and amplitude during detection, so that the vibration load borne by the generator set 7 during the detection is closer to the actual operating environment.

[0087] S33. When the generator set 7 drives the column 42 and the corresponding locking assembly 5 to shake synchronously during the shaking process, at this time, the corresponding locking assembly 5 pulls the corresponding U-shaped frame 68 and the micro cylinder 69, and the U-shaped frame 68 drives the sliding rod 66 to slide inside the corresponding vertical pipe 65, and the rope 601 is pulled. When the shaking amplitude of the generator set 7 is too large, the rope 601 can control the shaking amplitude of the generator set 7.

[0088] S4. After completing the detection under displacement and swinging actions, the generator set 7 is driven to move horizontally for a certain distance through the offset component 3. Then, the offset component 3 drives the generator set 7 to move centrifugally, thereby simulating the inertial load borne due to the change of motion trajectory in the hull turning scenario.

[0089] The more specific steps of S4 are:

[0090] S41. After completing the detection under displacement and swinging actions, the placement seat 31 is driven by the electric slide 36 to move horizontally for a certain distance, causing the placement seat 31 and the generator set 7 to move away from the rotation center of the turntable 35. Then, the drive motor 34 drives the turntable 35, the electric slide 36, the placement seat 31 and the generator set 7 to move centrifugally, thereby simulating the inertial load borne due to the change of motion trajectory in the ship turning scenario.

[0091] S5. After the test is completed, the connecting assembly 6 is separated from the locking assembly 5. Then, the locking assembly 5 cancels the positioning state of the generator set 7. Then, the generator set 7 can be lifted and removed using the lifting equipment.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.
