Description

TECHNICAL FIELD

[0001] The utility model belongs to unmanned ship charging technical field especially relates to an unmanned ship sea charging device. BACKGROUND

[0002] The unmanned ship is a kind of device that unmanned drives on the horizontal plane, and the unmanned ship can be used to carry out tasks such as sea patrol, sea investigation and sea task execution. Since the unmanned ship is unmanned, it has very high mobility and flexibility and is suitable for executing tasks with high risk coefficient on the sea.

[0003] During the execution of the task on the sea, the unmanned ship needs to face a major technical problem, that is, the endurance problem of the unmanned ship. When the power of the unmanned ship is insufficient to support the return of the unmanned ship during the execution of the task, the unmanned ship cannot return. Even if a backup power source is installed on the unmanned ship, the backup power source cannot support sufficient endurance time of the unmanned ship during the actual work process, such as long-term execution of the task by the unmanned ship.

[0004] The main reason for the above technical defects is that the unmanned ship cannot be charged during the execution of the task on the sea, especially during the execution of the long-range task. The specific reason is that a charging base station with low cost and high flexibility cannot be set on the sea. The traditional sea platform with high cost is not only easy to be destroyed, but also has low flexibility and long construction time.

[0005] Therefore, in the actual work process, since the unmanned ship cannot be charged during the sea cruise, the unmanned ship can only execute the task for a short time and cannot execute the task remotely, which causes the unmanned ship to have high limitations in the actual application process.

[0006] With the development of technology, unmanned operation has gradually become a mainstream technology, so if a sea charging platform with low cost, fast laying speed, high mobility and flexibility cannot be provided, the application bottleneck of the unmanned ship on the sea will be difficult to break through.

[0039] Example 1

[0040] like Figures 1-5 As shown, an unmanned surface vessel (USV) marine charging device includes a floating platform 1 that floats on the sea, with solar charging panels installed on both sides of the platform 1. This structure enables the USV to pre-position the marine charging device in the sea area where it will perform its mission during operation. GPS is installed on the floating platform 1 in a conventional manner, allowing the USV to quickly locate the nearest charging device for recharging.

[0041] The unmanned ship sea charging device further comprises an unmanned ship lifting mechanism 4 hingedly arranged at the left end of the floating plate 1. Normally, the unmanned ship lifting mechanism 4 is immersed in water. When the unmanned ship is charged, the unmanned ship (small) drives above the unmanned ship lifting mechanism 4, and the unmanned ship is lifted by the unmanned ship lifting mechanism 4. In this way, the stability of the unmanned ship during the charging process is maintained (the reason why the unmanned ship floating on the sea cannot be charged is that the unmanned ship is easily shaken by the flow).

[0042] Specifically, the unmanned ship lifting mechanism 4 comprises a lifting frame 41 of a rectangular structure. The front and back sides of the lifting frame 41 are lifting frame 41 beams. Support beams are welded between the lifting frame 41 beams and arranged on the left and right sides. The unmanned ship drives into the lifting frame 41. When the lifting frame 41 is lifted, the unmanned ship is supported on the support beams on both sides.

[0043] In actual work, in order to ensure that the unmanned ship is stably supported on the support beams on both sides, a pressure sensor (not shown in the figure) is installed on the support beam in the conventional manner disclosed in the prior art. That is, when the lifting frame 41 is lifted, the pressure sensors on the support beams on both sides feedback pressure signals, indicating that the unmanned ship is stably supported. Otherwise, the lifting frame 41 is lowered again, and the unmanned ship is repositioned.

[0044] In order to stably lift the lifting frame 41, the lifting arms 42 are hingedly arranged on both sides of the lifting frame 41. The unmanned ship lifting mechanism 4 further comprises a driving structure for driving the lifting of the lifting frame 41. When the unmanned ship drives onto the lifting frame 41, the driving structure drives the lifting frame 41 to be lifted above the floating plate 1.

[0045] Specifically, the outer end of the lifting arm 42 is hingedly connected to the center of the lifting frame 41 (to keep the lifting frame 41 horizontal during the process of turning over the lifting frame 41). Meanwhile, the inner end of the lifting arm 42 is fixedly connected with a rotating shaft, and the rotating shaft is rotatably connected to the floating plate 1. The end of the rotating shaft penetrates from the position of the lifting arm 42.

[0046] The driving structure comprises a gear 43 fixedly installed on the rotating shaft. The driving structure further comprises a driving rotating shaft rotatably connected to the floating plate 1 (according to the conventional rotatable connection manner disclosed in the prior art, the front and rear sidewalls of the floating plate 1 are provided with adapted bearings). The driving rotating shaft is fixedly provided with driving gears 44 engaging with the gears 43 at both ends. Meanwhile, the driving structure further comprises a driven gear 45 fixedly installed on the driving rotating shaft. The driven gear 45 engages with a driving gear 46. The driving gear 46 is installed with a motor 47. The motor 47 is fixedly installed in the floating plate 1.

[0047] Specifically, a cavity structure is formed in the floating plate 1, which is adapted to the structures of the driving rotating shaft, the driven gear 45, the driving gear 46, the motor 47, etc.

[0048] When the unmanned ship is parked in the lifting frame 41 during the working process, the motor 47 is turned on, the lifting frame 41 lifts the unmanned ship and moves it to the position of the mechanical arm mechanism at the rear end of the floating plate 1.

[0049] Through the above structure, the floating plate 1 and the solar charging plate structure realize offshore floating as a charging base station during the working process. Because the floating plate 1, the solar charging plate and other structures have low cost and simple laying method, they can be directly placed on the sea. Therefore, as an offshore temporary charging base station, the unmanned ship can be charged and sustained for the task. The lifting frame 41 and other structures lift the unmanned ship during the charging process, maintaining the stability of the unmanned ship during the charging process.

[0050] Embodiment 2

[0051] As shown in Figures 1-5 , this embodiment is based on the structure of embodiment 1. In order to further improve the mobility of the floating plate 1, the motor and impeller structure (not shown in the figure) that drives the floating plate 1 to move can be installed on each side of the floating plate 1 according to the existing method. The impeller can carry the floating plate 1 to move under the drive of the motor. When the unmanned ship cannot reach the position of the floating plate 1 due to insufficient power, the unmanned ship can be moved by the floating plate 1 to approach the floating plate 1.

[0052] Embodiment 3

[0053] As shown in Figures 1-5 , this embodiment is based on the structure of embodiment 1. When the unmanned ship is lifted, it cannot be connected to the power supply for charging. Therefore, the above-mentioned offshore charging device for unmanned ship also includes a mechanical arm mechanism 3, which is installed with a charging connector 31 matched with the charging interface of the unmanned ship. The charging connector 31 is a charging connector 31 disclosed in the prior art that is adapted to the charging interface on the unmanned ship. The charging line is electrically connected to the battery module.

[0054] Specifically, the mechanical arm mechanism includes a mechanical arm 32 (the same as the existing mechanical arm, which includes an arm body part that can be adjusted in angle and length, and a turntable part 33 that drives the arm body part to rotate) fixedly installed at the other end of the floating plate 1. The charging connector 31 is installed on the mechanical arm 32. The charging connector 31 is installed on the operating end of the mechanical arm, which is the same as the existing method.

[0055] During the working process, when the unmanned ship is lifted, the mechanical arm operates the charging connector 31 to insert it into the charging interface on the unmanned ship.

[0056] Through the above-mentioned method, automatic charging is realized, and the technical defect that the unmanned ship cannot be charged by itself due to the lack of human operation is solved.

[0057] Example 4

[0058] like Figures 1-5 As shown, this embodiment, based on the structure of embodiment 3, includes a side floating plate 11 fixedly connected to the side wall of the floating plate 1, with a solar panel structure mounted on the top of the side floating plate 11. The solar charging panel structure also includes a battery module 5 that cooperates with the solar panel structure, and a charging connector 31 is electrically connected to the battery module 5. Specifically, similar to the prior art, the solar charging panel structure includes a solar panel 2 and a bracket 21 for mounting the solar panel 2, with the bracket 21 fixedly mounted on the top of the side floating plate 11.

[0059] Similar to existing technologies, the battery module 5 is charged via a solar charging panel. Because the entire device remains afloat at sea year-round, the battery module 5 always maintains sufficient charge.

[0060] Example 5

[0061] like Figures 1-5 As shown, this embodiment, based on the structure of embodiment 4, can improve the installation method of the battery module on the unmanned surface vessel (USV) during actual operation. For example, a removable mobile power supply can be used as the power source for the USV. This can be achieved by attaching a gripper (not shown in the figure) to a robotic arm, removing the mobile power supply from the USV, grabbing the battery module 5, and directly installing it onto the raised USV. The USV can then be lowered to continue performing its mission.

[0062] This method can restore the unmanned surface vessel's power in a very short time compared to the charging methods mentioned above.

[0063] Example 6

[0064] like Figures 1-5 As shown, in this embodiment, based on the structure of embodiment 5, several weighted ball structures are installed at the bottom of the float 1; the weighted ball structures are used to increase the weight of the float 1. By increasing the weight of the float 1 through the weighted ball structures, the draft of the float 1 is increased, thereby increasing the stability of the float 1. For example, when the sea surface is in a large wave, the stability is improved by the weighted ball structures.

[0065] Specifically, the weighted sphere structure includes a hollow weighted float 6.

[0066] Meanwhile, in order to change the weight of the weighted ball during actual operation, such as when the wind force is small, the draft of the float 1 can be reduced to improve the maneuverability of the float 1. The bottom of the aforementioned weighted float 6 is connected to a water inlet pipe 61, and an electromagnetic valve 62 is installed on the water inlet pipe 61.

[0067] Correspondingly, the top of the weighted floating ball 6 is communicated with a vacuum pipe, and an electromagnetic valve 62 is installed on the vacuum pipe. The vacuum pipe is fixedly installed at the bottom of the floating plate 1.

[0068] According to the water-absorbing and weight-increasing mode of the prior art floating ball, a vacuum pump is installed at the top of the floating plate 1. The electromagnetic valve 62 on each vacuum pipe is opened by connecting each vacuum pipe to the vacuum pump through a pipeline system (the pipeline system is composed of a main pipe communicated with the vacuum pump and a plurality of side pipes each communicated with a vacuum pipe, and a valve is installed on each side pipe). The internal pressure of the weighted floating ball 6 is reduced. Then, the electromagnetic valve 62 on the water inlet pipe 61 is opened, and seawater is absorbed into the weighted floating ball 6 to increase the weight. The amount of absorption can be controlled by adjusting the negative pressure in the weighted floating ball 6.

[0069] Of course, the above description is not a limitation of the present application, and the present application is not limited to the above examples. Changes, modifications, additions or replacements made by the skilled in the art within the scope of the present application should also be within the protection scope of the present application.
