Description

Technical Field

[0001] The utility model relates to the technical field of diesel generator brackets, in particular to a self-balancing supporting device for a diesel generator set for an offshore platform. Background Art

[0002] An offshore platform is a structure that provides production and living facilities for activities such as drilling, oil production, shipping, observation, navigation, and construction at sea. With the continuous development of marine resources, the demand for diesel generator sets on offshore platforms is increasing.

[0003] However, the marine environment is complex and changeable. Natural factors such as wind and waves can easily cause the offshore platform to vibrate and tilt. The tilted diesel generator set will cause the gap between the internal rotor and stator to change. As the operation continues, the friction between the two will increase, which can easily cause the diesel generator set to fail and bring safety hazards. Therefore, in response to the above problems, we propose a new self-balancing support device for diesel generator sets for offshore platforms. Utility Model Content

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4As shown, the utility model provides a self-balancing support device for a diesel generator set for an offshore platform, comprising a base mechanism 1, an adjusting mechanism 2 is arranged on the top of the base mechanism 1, a platform mechanism 3 is arranged on the top of the adjusting mechanism 2, the base mechanism 1 comprises a lower base 101, a mounting frame 102 is fixedly connected to the top of the lower base 101 near the edge, the inner surface wall of the mounting frame 102 is inclined, the adjusting mechanism 2 comprises a connecting column 203, a first ball head rod 202 is fixedly connected to the bottom of the connecting column 203, a second ball head seat 201 is movably connected to the bottom end of the first ball head rod 202, a third ball head seat 204 is installed near the top of the outer surface of the connecting column 203, a second ball head rod 205 is movably connected to the bottom end of the third ball head seat 204, a hydraulic cylinder 2 is installed at the bottom end of the second ball head rod 205 06, the second ball head seat 201 is fixedly connected to the top center of the lower base 101, the bottom end of the hydraulic cylinder 206 is fixedly connected to the third ball head rod 207, the first ball head seat 103 is fixedly connected to the inner surface wall slope of the mounting frame 102, the first ball head seat 103 and the third ball head rod 207 are movably connected, the platform mechanism 3 includes a connecting platform 301, the bottom of the connecting platform 301 is fixedly connected to the top of the connecting column 203, a posture sensor 302 is installed at the bottom of the connecting platform 301, the top of the lower base 101 near the inner side is installed with a power supply battery 104, a processor 105 and a hydraulic station 106, the processor 105, the hydraulic station 106, the posture sensor 302 and the power supply battery 104 are electrically connected to each other through lines, and the output end of the hydraulic station 106 is connected to the four hydraulic cylinders 206 through an oil pipe.

[0023] The effect achieved by the entire embodiment 1 is that by fixing the lower base 101 to the original installation position of the diesel generator set on the offshore platform, and then fixing the diesel generator set to the mounting plate 305, when the offshore platform tilts due to factors such as wind and waves, the attitude sensor 302 will detect the attitude change of the connecting platform 301 through the internal accelerometer and gyroscope, and send the detected data to the processor 105 for analysis and processing. According to the inclination angle of the connecting platform 301 obtained based on the feedback data, the processor 105 sends a start signal to the hydraulic station 106, and the hydraulic station 106 controls the hydraulic cylinders 206 on the four sides of the connecting column 203 to extend and retract. When the hydraulic cylinders 206 extend and retract, the tail ends will pass through the third ball head seat 2 04 and the second ball head rod 205 will adaptively rotate with the connecting column 203, and the top will adaptively rotate with the inclined surface of the mounting frame 102 through the third ball head rod 207 and the first ball head seat 103. After the four hydraulic cylinders 206 are extended and retracted to different degrees, the upper end of the connecting column 203 can be pulled to any angle within a certain range, and the bottom of the connecting column 203 will maintain an active connection with the top center of the lower base 101 through the first ball head rod 202 and the second ball head seat 201, thereby automatically adjusting the connecting platform 301 to a horizontal state, thereby avoiding the problem that the diesel generator set is prone to malfunction or even safety accidents when running in an inclined state for a long time. The battery 104 is mainly used to power other electrical devices.

[0024] Embodiment 2, as Figure 1-Figure 4 As shown, dampers 303 are installed at the inner bottom of the connecting platform 301 near the four corners, a spring 304 is sleeved outside the damper 303, and a mounting plate 305 is fixedly connected between the damper 303 and the top of the spring 304.

[0025] The effect achieved by the entire embodiment 2 is that when the marine platform is bumped and vibrated during activities at sea, the damper 303 and the spring 304 will absorb energy by expansion and contraction, thereby reducing the vibration intensity transmitted from the connecting platform 301 to the mounting plate 305, thereby achieving the effect of shock-absorbing and protecting the diesel generator set on the top of the mounting plate 305, and improving the service life and stability of the diesel generator set.

[0026] Working principle: When the offshore platform tilts due to factors such as wind and waves, the attitude sensor 302 will detect the attitude change of the connecting platform 301 through the internal accelerometer and gyroscope, and send the detected data to the processor 105 for analysis and processing. According to the inclination angle of the connecting platform 301 obtained from the feedback data, the processor 105 sends a start signal to the hydraulic station 106, and the hydraulic station 106 controls the extension and retraction of the hydraulic cylinders 206 on the four sides of the connecting column 203. When the hydraulic cylinder 206 is extended or retracted, the tail end will adaptively rotate with the connecting column 203 through the third ball head seat 204 and the second ball head rod 205, and the top end will adaptively rotate with the inclined surface of the mounting frame 102 through the third ball head rod 207 and the first ball head seat 103. The four hydraulic cylinders 206 perform different After a certain degree of expansion and contraction, the upper end of the connecting column 203 can be pulled toward any angle within a certain range, and the bottom of the connecting column 203 will maintain an active connection with the top center of the lower base 101 through the first ball head rod 202 and the second ball head seat 201, thereby automatically adjusting the connecting platform 301 to a horizontal state, thereby avoiding the problem that the diesel generator set is prone to malfunction or even safety accidents when running in an inclined state for a long time. In addition, when the marine platform is bumped and vibrated during activities at sea, the damper 303 and the spring 304 will buffer and absorb energy through expansion and contraction, thereby reducing the vibration intensity transmitted to the mounting plate 305 by the connecting platform 301, which has the effect of shock-absorbing and protecting the diesel generator set on the top of the mounting plate 305, and improving the service life and stability of the diesel generator set.
