Description

Technical Field

[0001] This invention relates to the field of marine fuel filling equipment technology, and in particular to a hydraulic marine fuel filling equipment equipped with optical calibration equipment. Background Technology

[0002] Marine fuel filling is a core supporting process in ship operation and maintenance and shipping operations. The operational accuracy, stability and ease of operation of filling equipment directly affect the efficiency of ship fuel replenishment, operational safety and shipping economy. It is a key piece of equipment to ensure the normal navigation and operation of ships.

[0003] Currently, most commercially available marine fuel filling equipment uses hydraulic systems as its core drive and control structure. Key processes such as alignment and filling adjustment rely on manual calibration and positioning. While this traditional control method is a common industry solution, with a mature structure and wide application, it exposes numerous technical shortcomings in actual ship operation scenarios. The complex marine operating environment means that traditional hydraulic filling equipment experiences swaying displacement during fuel adjustment and alignment, easily leading to problems such as filling position deviation and pipeline connection misalignment, significantly reducing the stability and accuracy of fuel filling operations.

[0004] In addition, when connecting the pipelines of traditional filling equipment to the ship's fuel interface, operators need to manually drag the pipelines from the side of the ship to complete the connection. This is not only labor-intensive and inefficient, but the pipelines are also prone to violent shaking under the swaying of the ship caused by waves, which increases the safety risk of pipeline damage and leakage.

[0005] Furthermore, existing hydraulic filling equipment has a fixed boom length and limited adjustment range, making it difficult to adapt to changes in the fuel filling port position of vessels of different tonnages under different water levels. This results in poor equipment versatility and high modification and maintenance costs. When the filling port position deviates from the equipment's reference plane, repeated adjustments to the vessel position or the filling equipment position are required to complete the docking, further reducing the efficiency of the filling operation.

[0006] Therefore, how to achieve automatic and accurate alignment of filling equipment in a dynamic marine environment, reduce the labor intensity of manual calibration, improve the stability and safety of filling operations, and at the same time expand the applicability and adjustment flexibility of the equipment are technical problems that urgently need to be solved in this field. Summary of the Invention

[0007] The technical problem to be solved by this invention is that the marine fuel filling equipment currently on the market relies on manual operation for calibration and positioning, and its stability is relatively limited during control.

[0008] The technical solution adopted by the present invention to solve its technical problem is: a hydraulic marine fuel filling device with optical calibration equipment, including a mounting column, a steel structure inner arm movably mounted on the mounting column through a top slewing support, a steel structure outer arm movably mounted at the end of the steel structure inner arm through an end slewing support, an end extension arm slidably assembled at the outer end of the steel structure outer arm, an electrically controlled optical calibration probe movably assembled at the outer end of the end extension arm, and an extended external stabilizing arm movably assembled at the outer end of the end extension arm.

[0009] Furthermore, a first hydraulic adjusting strut for controlling the horizontal rotation of the top slewing support is installed between the mounting column and the top slewing support; a second hydraulic adjusting strut for controlling the longitudinal rotation of the inner steel structure arm is installed between the top slewing support and the inner steel structure arm; and a third hydraulic adjusting strut for controlling the longitudinal rotation of the outer steel structure arm is installed between the inner steel structure arm and the outer steel structure arm.

[0010] Furthermore, liquid phase pipelines and gas phase pipelines are installed on the mounting columns, inner steel structure arm, outer steel structure arm, and end extension arm.

[0011] Furthermore, an internal guide rail is installed on the inner wall of the steel structure outer arm end. The end extension arm is inserted into the internal guide rail via a lateral slider and slidably assembled with the internal guide rail. An internal hydraulic adjusting strut is installed on the inner end of the internal guide rail to control the sliding of the end extension arm.

[0012] Furthermore, the outer end of the end extension arm is movably fitted with a hinged flip-type mounting base and a hydraulic angle adjustment strut for controlling the flip-type mounting base, and the electrically controlled optical calibration probe is fixedly mounted on the outer side of the flip-type mounting base.

[0013] Furthermore, the flip-up mounting base is also equipped with an electronic level sensor for automatically adjusting the hydraulic angle-adjusting strut.

[0014] Furthermore, the extended external stabilizer arm includes a first electrically controlled winding machine, a second electrically controlled winding machine, and an external adjustment sleeve fitted onto the outer surface of the end extension arm.

[0015] Furthermore, the first electrically controlled winding machine is connected to the external adjusting sleeve, and the second electrically controlled winding machine is connected to the external adjusting sleeve via a stabilizing pull rope.

[0016] Furthermore, the external regulating sleeve includes a sliding regulating sleeve that is movably fitted onto the liquid phase pipeline, a drive wheel assembly mounted on the sliding regulating sleeve, and a magnetically controlled locking block.

[0017] Furthermore, the sliding adjustment sleeve has several lateral mounting ports, the drive wheel assembly includes a main drive wheel and a driven support wheel installed inside the lateral mounting ports, and the magnetic locking block includes an internal partition plate installed in the lateral mounting ports, an internal telescopic block, an iron spring, and an electromagnet installed on the internal partition plate for controlling the iron spring.

[0018] The beneficial effects of this invention are as follows: This invention employs an electrically controlled optical calibration probe in conjunction with an electronic level sensor, enabling automatic detection and real-time calibration of the filling interface's positional deviation, eliminating the need for manual alignment and significantly improving alignment accuracy and operational efficiency. Furthermore, this invention utilizes the stabilizing ropes between the first and second electrically controlled winding machines on the extended external stabilizing arm and the external adjusting sleeve to provide external support after pipeline docking, effectively suppressing pipeline swaying caused by ship rolling due to waves and reducing the risk of pipeline damage and leakage. Finally, this invention achieves flexible control of the filling equipment's arm extension length and precise docking positioning of the pipeline interface through the sliding adjustment of the end extension arm on the built-in guide rail and the magnetic locking structure of the external adjusting sleeve, significantly expanding its applicability to vessels of different tonnages and water levels.

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Reference Figures 1 to 3 This invention provides a hydraulic marine fuel filling device equipped with optical calibration equipment, including a mounting column 100, which is fixedly installed on a ship deck or dock platform. A steel inner arm 200 is movably mounted on the top of the mounting column 100 via a top slewing support 110, allowing the steel inner arm 200 to rotate horizontally. A steel outer arm 300 is movably mounted on the end of the steel inner arm 200 via an end slewing support 210, allowing the steel outer arm 300 to flip relative to the steel inner arm 200 in a longitudinal plane. An end extension arm 400 is slidably fitted to the outer end of the steel outer arm 300 via a built-in guide rail 310. The end extension arm 400 engages with the built-in guide rail 310 via a lateral slider 410, enabling telescoping along the axial direction of the steel outer arm 300. An electrically controlled optical calibration probe 500 and an extended external stabilizing arm 600 are movably mounted on the outer end of the end extension arm 400.

[0026] A first hydraulic adjusting strut 120 is installed between the mounting column 100 and the top slewing bearing 110 to drive the top slewing bearing 110 to rotate horizontally. A second hydraulic adjusting strut 220 is installed between the top slewing bearing 110 and the inner steel structure arm 200 to control the longitudinal tilting angle of the inner steel structure arm 200. A third hydraulic adjusting strut 320 is installed between the inner steel structure arm 200 and the outer steel structure arm 300 to control the longitudinal tilting angle of the outer steel structure arm 300. An internal hydraulic adjusting strut 420 is installed on the inner end of the internal guide rail 310 to drive the end extension arm 400 to slide along the internal guide rail 310. Each hydraulic adjusting strut can be a servo hydraulic cylinder or an electro-hydraulic actuator, and is independently driven by the controller according to operating commands or sensor feedback signals.

[0027] A flip-type mounting base 510 is hinged to the outer end of the end extension arm 400. A hydraulic angle adjustment strut 520 is installed between the flip-type mounting base 510 and the end extension arm 400 to control the flip angle of the flip-type mounting base 510. An electrically controlled optical calibration probe 500 is fixedly mounted on the outer side of the flip-type mounting base 510. The electrically controlled optical calibration probe 500 can be a laser positioning probe or an infrared imaging probe, used to detect the position and attitude of the ship's fuel filling port. An electronic level sensor 530 is also installed on the flip-type mounting base 510 to detect the levelness of the flip-type mounting base 510 in real time. The controller automatically adjusts the extension and retraction of the hydraulic angle adjustment strut 520 based on the feedback signal from the electronic level sensor 530 to ensure that the electrically controlled optical calibration probe 500 maintains a horizontal attitude during the detection process.

[0028] The extendable external stabilizing arm 600 includes a first electrically controlled winding machine 630, a second electrically controlled winding machine 631, and an external adjusting sleeve 700. Both the first electrically controlled winding machine 630 and the second electrically controlled winding machine 631 are fixedly installed on the outer end of the end extension arm 400. The external adjusting sleeve 700 is movably fitted onto the liquid phase pipeline 800. Both the first electrically controlled winding machine 630 and the second electrically controlled winding machine 631 are connected to the external adjusting sleeve 700 via stabilizing ropes 640. After the end extension arm 400 is deployed, the first electrically controlled winding machine 630 and the second electrically controlled winding machine 631 automatically release the stabilizing pull rope 640. The stabilizing pull rope 640 can improve the stability of the external adjusting sleeve 700 sliding along the liquid phase pipeline 800. The external adjusting sleeve 700 can slide along the liquid phase pipeline 800, thereby adjusting its stable position as needed. The stabilizing pull rope 640 of the first electrically controlled winding machine 630 bypasses the guide wheel assembly located at the end of the end extension arm 400 and connects with the external adjusting... One side of the sleeve 700 is connected, and the stabilizing pull rope 640 of the second electrically controlled winding machine 631 is connected to the other side of the external adjusting sleeve 700. By winding and unwinding from both sides, the angle of the liquid phase pipeline 800 is changed. Through the active drive of the drive wheel set 720 and the locking and positioning of the magnetically controlled locking block 730, the external adjusting sleeve 700 is fixed on the liquid phase pipeline 800, so that the end extension arm 400, the stabilizing pull rope 640 and the external adjusting sleeve 700 form an external support structure for the liquid phase pipeline.

[0029] The external adjusting sleeve 700 includes a sliding adjusting sleeve 710 and a drive wheel assembly 720 and a magnetically controlled locking block 730 mounted on the sliding adjusting sleeve 710. The drive wheel assembly 720 includes a main drive wheel 721 and a driven support wheel 722. The magnetically controlled locking block 730 includes a built-in partition 731, an internal telescopic block 732, an iron spring 733, and an electromagnet 734. Under normal conditions, the electromagnet 734 is energized to generate magnetic force that attracts the iron spring 733, causing the internal telescopic block 732 to retract and unlock, allowing the sliding adjusting sleeve 710 to slide freely on the liquid phase pipeline 800. When locking is required, the electromagnet 734 is de-energized, the iron spring 733 resets, and pushes the internal telescopic block 732 out to clamp the liquid phase pipeline 800, achieving locking and positioning.

[0030] The operation of the filling equipment of the present invention is as follows: The operator issues a filling command through the controller. The controller first controls the extension and retraction of the first hydraulic adjusting support rod 120 to drive the top slewing bearing 110 to rotate, so that the inner steel structure arm 200 rotates in the horizontal plane to align with the ship's fuel filling port; then, the controller controls the second hydraulic adjusting support rod 220 and the third hydraulic adjusting support rod 320 to extend the inner steel structure arm 200 and the outer steel structure arm 300 to a preset height and angle; then, the controller controls the built-in hydraulic adjusting support rod 420 to push the end extension arm 400 to extend outward along the built-in guide rail 310, bringing the liquid phase pipeline 800 closer to the ship's fuel filling port; the electrically controlled optical calibration probe 500 starts scanning to detect fuel filling. The three-dimensional position coordinates of the filling port are simultaneously detected by the electronic level sensor 530, which monitors the levelness of the flip-type mounting base 510. The controller calculates the deviation based on feedback signals from the probe and sensor, and automatically adjusts the hydraulic angle adjustment strut 520 to precisely align the electrically controlled optical calibration probe 500 with the filling port. After confirming that the alignment accuracy meets the requirements, the controller controls the first electrically controlled winding machine 630 and the second electrically controlled winding machine 631 to release the stabilizing pull rope 640. The stabilizing pull rope 640 drives the external adjusting sleeve 700 to slide axially along the liquid phase pipeline 800 to the vicinity of the filling port, where the magnetically controlled locking block 730 locks it in place. Finally, the fuel filling pump is started to deliver fuel through the liquid phase pipeline 800, while the gas phase pipeline 810 simultaneously recovers fuel vapor. After filling is completed, the above actions are reversed to retract the booms and stabilizing structures, completing the entire filling process.

The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
