Description

Technical Field

[0001] The invention belongs to the technical field of power supply equipment, and in particular relates to a mobile ship-used power supply equipment. Background Art

[0002] At present, most ports use charging piles to charge small electric ships. Charging piles are generally divided into two types: DC charging and AC charging. DC charging is a way of adjusting the voltage of DC power through a rectifier module to power the battery pack. This power supply method can greatly reduce the AC transformer and rectifier equipment in the cabin, which saves space. However, due to the low DC charging voltage, high-power charging is not possible, which greatly affects the charging efficiency. AC charging is to send AC power directly to the AC transformer and rectifier equipment on board through cables. This method can increase the charging power and improve the charging efficiency, but it requires additional AC-to-DC conversion related equipment, which occupies a larger space in the cabin.

[0024] Figures 1 to 6 The mobile ship power supply device provided by the present invention includes a power supply system 1, a mechanical arm 2, an adaptive regulator 3, a charging module 4, an active regulator 6 and a control unit 7.

[0025] The power supply system 1 is electrically connected to the manipulator 2. The manipulator 2 is provided with an amplitude-changing drive device 23, which is used to drive the manipulator 2 to change its amplitude. The control unit 7 can control the amplitude-changing drive device 23 to change the amplitude of the manipulator 2. The adaptive regulator 3 includes a retractable sliding power connection component 31, which is connected to the manipulator 2 and powered on, and the charging module 4 is connected to the sliding power connection component 31 and powered on. The power supply system 1 can supply power to the charging module 4 through the manipulator 2 and the sliding power connection component 31. The charging module 4 can cooperate with the power receiving module 5 provided on the hull to realize power supply to the hull. The position of the hull is affected by the surge of waves. By controlling the amplitude change of the manipulator 2 through the amplitude-changing drive device 23, the position of the charging module 4 can be adjusted so that the charging module 4 moves to a position corresponding to the power receiving module 5 on the hull, thereby facilitating coordinated charging.

[0026] The active regulator 6 includes a position detection device 61, which is used to detect the position signal of the power receiving module 5. The control unit 7 is used to receive the position signal of the power receiving module 5, and control the amplitude change drive device 23 to drive the mechanical arm 2 to change the amplitude based on the position signal, that is, to adjust the pitch of the mechanical arm 2, etc., so as to realize automatic adjustment of the position of the charging module 4.

[0027] After the charging module 4 cooperates with the power receiving module 5, the power receiving module 5 rises and falls with the hull and causes the charging module 4 to be stressed, the adaptive regulator 3 is passively stressed, and the sliding power connection component 31 can be extended and retracted with the rise and fall of the charging module 4, so that the charging module 4 can adapt to the position change of the power receiving module 5, and can continuously supply power to the charging module 4. The power supply system 1 and the robotic arm 2 can be set on the vehicle as a vehicle-mounted power supply device to improve maneuverability and flexibility. The active regulator 6 and the control unit 7 can also be set on the vehicle. The power supply system 1 can be used to provide direct current to the hull, and can also be used to provide alternating current to the hull.

[0028] In some embodiments, Figure 2 As shown, the power supply system 1 includes an AC high-voltage incoming line cabinet 11 and a rectifier 14. The AC high-voltage incoming line cabinet 11 is used as a main switch on the load side to carry the entire bus current. The rectifier 14 is used to convert the AC power provided by the AC high-voltage incoming line cabinet 11 into DC power, thereby providing DC power to the hull. The rectifier 14 can be electrically connected to the manipulator 2. The rectifier 14 can use a water-cooled flat-plate diode.

[0029] Further, continue to refer to Figure 2 The power supply system 1 may further include a transformer 12, a reactor 13 and a cooling device 15. The transformer 12 is used to reduce the high voltage and isolate the AC power supply safely. The reactor 13 is used to increase the short-circuit impedance and limit the short-circuit current. The transformer 12 and the reactor 13 may be connected between the AC high-voltage incoming line cabinet 11 and the rectifier 14. The cooling device 15 is used to cool the power supply system 1.

[0030] Specifically, the AC high-voltage incoming line cabinet 11 and the transformer device 12 may be connected via a copper busbar, the transformer device 12 and the reactor device 13 may be connected via a copper busbar, and the reactor device 13 and the rectifier device 14 may be connected via a copper busbar.

[0031] The power supply required by the power supply system 1 can be provided by a box transformer or a shore power high-voltage power supply. Connect the high-voltage AC power supply to the AC high-voltage incoming line cabinet 11, check that there is no problem, and close the switch. After the power is transformed and rectified, it is transmitted to the power receiving module 5 through the mechanical arm 2.

[0032] In some embodiments, Figure 2 As shown, the mechanical arm 2 includes a central column 21, a luffing arm 22 and a boom 24 which are connected and powered in sequence. The central column 21 and the luffing arm 22 are movably connected. The luffing drive device 23 is arranged between the central column 21 and the luffing arm 22, and can drive the luffing arm 22 to rotate up and down relative to the central column 21 to adjust the pitch angle. The luffing arm 22 is fixedly connected to the boom 24, and the luffing arm 22 can drive the boom 24 to adjust the pitch angle.

[0033] Specifically, the bottom end of the center column 21 can be installed on the vehicle, and the luffing arm 22 can be connected to the top end of the center column 21 through a horizontal rotating shaft. One end of the upper arm 24 is fixedly connected to the luffing arm 22, and the other end extends outward.

[0034] In some embodiments, Figure 2As shown, a hanging arm 25 is provided at the end of the robot arm 2, and the adaptive regulator 3 and the charging module 4 are arranged on the hanging arm 25. The hanging arm 25 is composed of a soft connecting conductor, such as a soft copper busbar, which has good bendability and toughness. When the charging module 4 is subjected to force as the power receiving module 5 rises and falls, the hanging arm 25 can be deformed and adjusted to a certain extent to adapt to the rise and fall of the position of the charging module 4.

[0035] The luffing arm 22, the main arm 24 and the vertical arm 25 can all use copper bars to transmit electricity, and the connection between the arms can be made by soft copper bar connection to ensure the safe passage of large currents.

[0036] The adaptive regulator 3 can be arranged at the top, middle or bottom of the hanging arm 25. The charging module 4 can be arranged at the bottom end of the hanging arm 25. The sliding power connection component 31 of the adaptive regulator 3 can be connected to the charging module 4 through the hanging arm 25 and powered, or the adaptive regulator 3 can be connected to the bottom end of the hanging arm 25, and the charging module 4 is directly connected to the sliding power connection component 31.

[0037] The sliding power connection assembly 31 or the hanging arm 25 is movably connected to the end of the big arm 24. The hanging arm 25 hangs below the big arm 24 and can swing below the big arm 24 to improve flexibility. When the sliding power connection assembly 31 is set at the top of the hanging arm 25, the sliding power connection assembly 31 is connected to the big arm 24 through a movable joint. When the sliding power connection assembly 31 is set in the middle or lower end of the hanging arm 25, the top of the hanging arm 25 is connected to the big arm 24 through a movable joint.

[0038] In some embodiments, Figure 3 As shown, the adaptive regulator 3 further includes a buffer device 32, and the buffer device 32 is configured to be synchronously extended and retracted with the sliding electrical connection assembly 31. The buffer device 32 can absorb pressure or tension, and play a buffering and protective role.

[0039] In some embodiments, Figure 3 As shown, the sliding power connection assembly 31 includes a fixed conductor 311 and a sliding conductor 312 in sliding contact. The robot arm 2 is connected to the fixed conductor 311 and powered, and the charging module 4 is connected to the sliding conductor 312 and powered. The fixed conductor 311 and the sliding conductor 312 can maintain contact and power during relative sliding. Specifically, the fixed conductor 311 is connected to the large arm 24 and powered.

[0040] The buffer device 32 may be connected between the fixed conductor 311 and the sliding conductor 312 , and the buffer device 32 may be a pneumatic buffer, a hydraulic buffer, a spring buffer, or the like.

[0041] like Figure 3In the specific embodiment shown, the adaptive regulator 3 can be arranged at the top end of the vertical arm 25, and the charging module 4 is arranged at the bottom end of the vertical arm 25. The vertical arm 25 is connected between the adaptive regulator 3 and the charging module 4. Specifically, the fixed conductor 311 is arranged as a sleeve structure, and the sliding conductor 312 is nested inside the fixed conductor 311 and can slide up and down in the fixed conductor 311. Specifically, the sliding conductor 312 can contact and cooperate with the inner wall of the sliding conductor 312 through the raised contact point. The vertical arm 25 is fixedly connected to the bottom of the sliding conductor 312 and extends downward. The buffer device 32 can be installed in the fixed conductor 311, one end of which is connected to the sliding conductor 312, and the other end is connected to the fixed conductor 311.

[0042] In some embodiments, the position detection device 61 of the active regulator 6 may be a radar, and the radar is used to detect the position of the power receiving module 5. The position detection device 61 may be installed on the robot arm 2, or on a vehicle.

[0043] like Figure 2 In one embodiment shown, the position detection device 61 is installed on the side of the center column 21. The active regulator 6 can also detect the position of the power receiving module 5 using other existing positioning technologies.

[0044] In some embodiments, Figure 4 As shown, the active regulator 6 also includes a force sensor 62, which is installed on the amplitude variation drive device 23 and is used to detect the force signal of the amplitude variation drive device 23. The control unit 7 is electrically connected to the force sensor 62 and receives the force signal. The control unit 7 is used to control the amplitude variation drive device 23 to drive the mechanical arm 2 to vary its amplitude based on the force signal.

[0045] When the hull's ups and downs exceed the adjustable capacity of the vertical arm 25 and the adaptive regulator 3, the force on the mechanical arm 2 increases, and the force sensor 62 can detect the increase in the force signal of the amplitude drive device 23. When the control unit 7 determines that the force signal exceeds the preset value, it sends a control signal to the amplitude drive device 23, actively controls the amplitude drive device 23 to adjust the pitch angle of the mechanical arm 2, thereby adjusting the position of the charging module 4 so that the charging module 4 is at the same height as the power receiving module 5.

[0046] The control unit 7 can monitor the stress condition of the variable amplitude drive device 23 in real time through the force sensor 62, and adjust the mechanical arm 2 in real time to adapt to the situation where the hull is constantly rising and falling with the waves on the sea surface.

[0047] When the hull rises due to surge fluctuations, the adaptive regulator 3 is forced to shorten and remain powered on, and the vertical arm 25 is deformed by force, and passive adjustment is performed. When the hull descends due to surge fluctuations, the vertical arm 25 is stretched and deformed by force, increasing its length, and the adaptive regulator 3 is stretched and continuously powered on, and passive adjustment is performed. When the hull descends beyond the limit of the vertical arm 25 and the limit of the adaptive regulator 3, the mechanical arm 2 is subjected to tension, and the force on the amplitude-changing drive device 23 increases. The active regulator 6 controls the amplitude-changing drive device 23 according to the force signal of the force sensor 62 to lower the height of the mechanical arm 2 so that the charging module 4 adapts to the position of the hull. At the same time, in the above-mentioned passive adjustment process, the active regulator 6 detects the position of the power receiving module 5 in real time through the position detection device 61, and actively adjusts the amplitude of the mechanical arm 2 according to the position of the power receiving module 5, and adjusts the position of the charging module 4.

[0048] The active regulation mode is combined with the passive regulation mode through the regulation functions of the drop arm 25, the adaptive regulator 3 and the active regulator 6, thereby ensuring the reliability of power supply and the safety of equipment.

[0049] In some embodiments, Figure 2 As shown, a slewing mechanism 26 is provided at the bottom of the center column 21 of the robot arm 2. The slewing mechanism 26 includes a slewing bearing and a slewing drive device. The slewing bearing can be installed on a vehicle. The slewing drive device is used to drive the center column 21 to rotate around an axis to adjust the direction of the robot arm 2. The axis can be the axis of the center column 21. The slewing drive device can be a drive motor.

[0050] like Figure 4 As shown, the control unit 7 can be electrically connected to the slewing drive device of the slewing mechanism 26 to control the slewing drive device to work. The slewing mechanism 26 rotates the center column 21 to adjust the direction of the robot arm 2, thereby adjusting the position of the charging module 4, and can also facilitate the storage of the robot arm 2.

[0051] In some embodiments, Figure 1 and Figure 2 As shown, the mobile ship power supply equipment also includes a carriage 9 for carrying the power supply system 1. The power supply system 1 is placed in the carriage 9. The center column 21 can be set on the rear side of the carriage 9. The upper arm 24 can be supported on the top of the carriage 9. The vertical arm 25 can be stored on the front side of the carriage 9, which is conducive to saving space and facilitating vehicle transfer.

[0052] In detail, a support frame 91 can be provided on the top of the carriage 9, and the arm 24 can be placed on the support frame 91. By rotating the direction of the mechanical arm 2 by the slewing mechanism 26, the arm 24 and the vertical arm 25 can be rotated toward the rear of the carriage 9 to get close to the hull.

[0053] In some embodiments, Figure 1 and Figure 2As shown, the mobile marine power supply equipment also includes a support mechanism 8, which is used to support the vehicle and improve the supporting stability of the vehicle when the vehicle is operating. The support mechanism 8 includes a plurality of support legs for being arranged at the bottom of the vehicle body, and the support legs can support the vehicle. Specifically, the support mechanism 8 includes a front additional leg 81, a rear additional leg 82 and a main support leg 83. The front additional leg 81 is close to the front of the vehicle body, the rear additional leg 82 is located below the car body 9, and the main support leg 83 is close to the bottom of the center column 21. The front additional leg 81, the rear additional leg 82 and the main support leg 83 respectively support the vehicle body through oil cylinders, and are controlled by the control unit 7. The front additional leg 81, the rear additional leg 82 and the main support leg 83 each have two oil cylinders for telescopic and jacking. When the telescopic oil cylinder is working, the corresponding support leg extends from the side of the vehicle body. When the jacking oil cylinder is working, the corresponding support leg is pushed to the ground to support the vehicle body.

[0054] The mobile marine power supply equipment also includes a power take-off and an oil pump system, which are used for taking power from the variable amplitude drive device 23 and the additional legs of the support mechanism 8, as well as steering of the slewing mechanism 26.

[0055] The control unit 7 of the mobile marine power supply device is used to control the operation of the variable amplitude drive device 23, the slewing mechanism 26, and the supporting mechanism 8. Figure 5 As shown, the control unit 7 realizes intelligent control through the control panel 70, and the control panel 70 is provided with knobs, buttons, operating rods, etc. for controlling the operation of the variable amplitude drive device 23, the slewing mechanism 26, and the support mechanism 8. The control of the control panel 70 can adopt mechanical interlocking, and can be switched by rotating control. When the support mechanism 8 is not in place, the variable amplitude drive device 23 and the slewing mechanism 26 cannot be controlled. The variable amplitude drive device 23 and the slewing mechanism 26 can be controlled using a rocker 701, and assisted by buttons. A level 702 can also be provided on the control panel 70, and the vehicle body can be leveled by the level.

[0056] When the control support mechanism 8 is working, the knob 703 on the control panel 70 is rotated to the "telescopic" position to control the telescopic cylinder of the support leg to work. The control panel 70 is also provided with a main support control lever 704 and an auxiliary support control lever 705. Pull the main support control lever 704 to the "extend / top" position, the main support leg 83 extends from the vehicle body side, pull the auxiliary support control lever 705 to the "extend / top" position, and the front additional leg 81 and the rear additional leg 82 extend from the vehicle body side. After reaching the maximum position, rotate the knob 703 to the "top-retract" position, pull the main support control lever 704 to the "extend / top" position, the main support leg 83 internal lifting cylinder will push the support leg to the ground, pull the auxiliary support control lever 705 to the "extend / top" position, and the front additional leg 81 and the rear additional leg 82 internal lifting cylinder will push the support leg to the ground. Accordingly, by rotating the knob 703 and pulling the main support control lever 704 and the auxiliary support control lever 705 to the "retracted / contracted" position, the front additional leg 81, the rear additional leg 82 and the main support leg 83 of the support mechanism 8 can be retracted.

[0057] When working, the vehicle carrying the mobile marine power supply equipment is parked at a suitable position, and the power is transferred to the oil pump through the power take-off and oil pump system. The front additional leg 81, the rear additional leg 82 and the main support leg 83 are controlled by the operation control panel 70 to extend to the limit, and the wheels are lifted off the ground, and the vehicle body is adjusted to a horizontal level. The slewing mechanism 26 is controlled by the operation control panel 70 to drive the mechanical arm 2 to rotate, so that the charging module 4 is close to the power receiving module 5 on the hull. The amplitude change drive device is controlled by the operation control panel 70 to drive the amplitude change arm 22 to change the amplitude, so that the charging module 4 is aligned with the power receiving module 5 for easy connection.

[0058] In some embodiments, Figure 6 As shown, the charging module 4 includes a housing 41, an opening is provided on the housing 41, a sliding seat 44 is provided inside the housing 41, and a DC positive contact arm 42 and a DC negative contact arm 43 connected to the sliding seat 44. The sliding seat 44 can slide relative to the housing 41, driving the DC positive contact arm 42 and the DC negative contact arm 43 to extend or retract from the opening of the housing 41.

[0059] In some embodiments, the mobile ship power supply device includes a power receiving module 5. Figure 6As shown, the power receiving module 5 includes a power receiving seat 51, on which a positive power receiving contact 52 and a negative power receiving contact 53 are provided. The positive power receiving contact 52 is used to connect to the DC positive contact arm 42, and the negative power receiving contact 53 is used to connect to the DC negative contact arm 43. After the DC positive contact arm 42 and the DC negative contact arm 43 extend out of the housing 41, they are respectively energized with the positive power receiving contact 52 and the negative power receiving contact 53, so that the charging module 4 charges the power receiving module 5. The positive power receiving contact 52 and the negative power receiving contact 53 of the power receiving module 5 are connected to the marine DC busbar incoming line cabinet through a copper busbar.

[0060] In some embodiments, Figure 6 As shown, the opening of the housing 41 is provided with an openable and closable hole cover 45, which can protect the structure inside the housing 41. The hole cover 45 can be installed by means of snap connection, thread connection, etc. The hole cover 45 can adopt a three-proof rotation cover, which can play the role of waterproof, moisture-proof, dust-proof, etc. When charging, the hole cover 45 can be removed to allow the DC positive contact arm 42 and the DC negative contact arm 43 to extend from the opening.

[0061] After the charging module 4 and the power receiving module 5 are connected, they are locked, for example, by an electromagnetic lock. A positioning structure can be set between the charging module 4 and the power receiving module 5 to ensure a stable connection without power outage. The positioning structure can be a plug-in connecting rod and a connecting hole, or a stud nut assembly, etc.

[0062] In some embodiments, Figure 6 As shown, one of the housing 41 and the power receiving seat 51 is provided with a connecting rod 46, and the other is provided with a connecting hole 54, and the connecting rod 46 is used to be plugged into the connecting hole 54 to achieve the connection between the housing 41 and the power receiving seat 51. Multiple connecting rods 46 and connecting holes 54 can be provided respectively, and can be plugged in one by one.

[0063] like Figure 6 In a specific embodiment shown, the housing 41 is provided with two connecting rods 46, and the two connecting rods 46 are located on the side of the housing 41 with an opening, and the power receiving seat 51 is provided with two connecting holes 54. When the charging module 4 and the power receiving module 5 are plugged in, the two connecting rods 46 are respectively inserted into the corresponding connecting holes 54.

[0064] Furthermore, a mechanical locking device may be provided between the connecting rod 46 and the connecting hole 54, and the mechanical locking device may be provided on the connecting rod 46 and / or the connecting hole 54. After the connecting rod 46 is plugged into the connecting hole 54, it is locked by the mechanical locking device to prevent the connecting rod 46 from being separated from the connecting hole 54, thereby ensuring that the charging module 4 and the power receiving module 5 are not disconnected. When the connecting rod 46 extends into the connecting hole 54 and reaches the limit position, the positive contact 52 and the negative contact 53 of the power receiving are completely combined with the DC positive contact arm 42 and the DC negative contact arm 43, and the mechanical locking device is automatically locked. Specifically, the mechanical locking device is locked by popping out the release pin.
