[0002] With the rapid development of ship electrification technology, new energy ships using box-type power supplies as their core power source are gradually becoming an important direction for green transformation in the water transport sector due to their advantages such as low pollution, low noise, and low operating costs. After a ship completes a voyage, if the box-type power supply is depleted (i.e., has insufficient power), it needs to be removed from the hull and recharged on shore.

[0034] With the rapid development of ship electrification technology, new energy vessels (such as inland waterway cargo ships, port operation vessels, and sightseeing cruise ships) that use containerized power supplies as their core power source are gradually becoming an important direction for the green transformation of the water transportation sector due to their advantages such as low pollution, low noise, and low operating costs. These vessels typically have large containerized power supply capacities. After a voyage, if the containerized power supply is depleted (i.e., insufficient power), it needs to be removed from the hull and a pre-charged containerized power supply from the shore is installed on the vessel to ensure continued navigation.

[0035] For a depleted box-type power supply, the tower crane on the shore lifts the depleted box-type power supply onto a container truck on the shore and transports it to the battery swapping station. The front-end crane lifts the depleted box-type power supply from the container truck and places it in the charging station for charging.

[0036] In related technologies, when charging a box-type power supply that is low on power, it is necessary to manually drag a thick and heavy charging cable and manually insert the charging gun after confirming that the charging plug is aligned with the charging socket on the box-type power supply.

[0037] The applicant of this application found that the heavy charging cable makes the manual charging process time-consuming, laborious, and inefficient.

[0038] Figure 1 This is a schematic diagram of the structure of a positioning device for a marine charging connector provided in an embodiment of this application, as shown below. Figure 1As shown, the positioning device 100 includes: a first support plate 101, an identification component 102, and an execution component ( Figure 1 (Not shown).

[0039] Identification component 102 is located on the first carrier plate 101. (Reference) Figures 1 to 3 The identification component 102 is used to obtain the positional deviation between the first carrier plate 101 and the second carrier plate 201 in the box-type power supply 200.

[0040] The first carrier plate 101 is provided with a first charging connector 301, one end of which is connected to the gun wire ( Figures 1 to 3 (Not shown) Connection.

[0041] refer to Figure 2 The second support plate 201 is disposed on the end face of the box-type power supply 200 and fixed to the end face of the box-type power supply 200 by bolts. At least one second support plate 201 may be disposed in the box-type power supply 200. Figure 2 The diagram shows two second support plates 201 disposed within a box-type power supply 200. (Reference) Figure 3 The second carrier plate 201 is provided with a second charging connector 202, which is used to connect with the other end of the first charging connector 201.

[0042] For example, the second charging connector 202 can be a charging socket. Figure 3 Three second charging connectors 202 are shown, and the first charging connector 301 may be a charging plug. Figure 1 Three first charging connectors 301 are shown.

[0043] The execution component is connected to the first carrier plate 101 and the identification component 102 respectively, and is used to receive the position deviation transmitted by the identification component 102 and adjust the attitude of the first carrier plate 101 based on the position deviation.

[0044] In this configuration, the first charging connector 301 on the first support plate 101 after the posture adjustment is aligned with the second charging connector 202.

[0045] In summary, this application provides a positioning device for a marine charging connector. This device acquires the positional deviation between a first support plate and a second support plate, and adjusts the attitude of the first support plate based on the positional deviation. After the attitude adjustment, the first charging connector on the first support plate is aligned with the second charging connector. Therefore, this positioning device can automatically position the second charging connector and automatically align the first and second charging connectors. Compared to manually aligning the first and second charging connectors, this significantly improves the efficiency of aligning the first and second charging connectors.

[0046] In some embodiments of this application, the positional deviation may include a positional offset in the target direction.

[0047] The identification component 102 is used to obtain the positional offset of the first support plate 101 and the second support plate 201 in the target direction when the parallelism between the first support plate 101 and the second support plate 201 is greater than or equal to a preset threshold.

[0048] In some embodiments of this application, the target direction may include a first direction and a second direction, and the position offset may include a first offset in the first direction and a second offset in the second direction.

[0049] refer to Figure 4 The recognition component 102 may include an image acquisition unit 1021 and a controller ( Figure 4 (Not shown), for example, the image acquisition device 1021 can be a camera, such as a 2D (dimension, D) camera or a 3D camera. Reference Figure 5 The second carrier plate 201 is also provided with a feature hole 203. The image acquisition device 1021 is used to take a picture of the second carrier plate 201 to obtain a first image and send the first image to the controller.

[0050] refer to Figure 5 The first direction Y is parallel to one side of the second bearing plate 201, and the second direction Z is parallel to the other side of the second bearing plate 201. The first direction Y is perpendicular to the second direction Z.

[0051] The controller can identify the actual position of the feature hole 203 in the first image. The actual position may include a first actual coordinate in the first direction Y and a second actual coordinate in the second direction Z. The controller can use the offset of the first actual coordinate relative to the first standard coordinate as the first offset, and the offset of the second actual coordinate relative to the second standard coordinate as the second offset.

[0052] Wherein, the first standard coordinate is the coordinate in the first direction Y of the standard position of the feature hole 203, and the second standard coordinate is the coordinate in the second direction Z of the standard position of the feature hole 203.

[0053] refer to Figure 6 The execution component 103 is used to control the first support plate 101 to deflect by a first offset amount along the first direction and to control the second support plate 201 to deflect by a second offset amount along the second direction, so that the actual position of the feature hole 203 is the same as the standard position.

[0054] For example, suppose the actual position of feature hole 203 in the first image is (a, b), that is, the first actual coordinate is a and the second actual coordinate is b, where a and b are both positive integers. The standard position of feature hole 203 is (0,0), therefore the first offset ∆Y is a and the second offset ∆Z is b.

[0055] Then the execution component 103 is used to control the first support plate 101 to shift by a first offset amount a along the first direction, and to control the second support plate 201 to shift by a second offset amount b along the second direction, so that the actual position of the feature hole 203 is aligned with the standard position.

[0056] In this embodiment of the application, the image acquisition device 1021 can acquire multiple first images, and the controller can obtain the actual positions of multiple feature holes 203 based on the multiple first images. For each feature hole 203 in the first image, the controller can determine a first offset and a second offset. Then, the controller can determine a target first offset based on the multiple first offsets and a target second offset based on the multiple second offsets.

[0057] The target first offset can be the mean or median of multiple first offsets, or the mean of a first intermediate array, which includes the remaining first offsets excluding the maximum and minimum values.

[0058] The target second offset can be the mean or median of multiple second offsets, or it can be the mean of a second intermediate array, wherein the second intermediate array includes the remaining second offsets excluding the maximum and minimum values.

[0059] In this embodiment of the application, the execution component 103 is used to control the first carrier plate 101 to offset the target first offset amount along the first direction, and to control the second carrier plate 201 to offset the target second offset amount along the second direction, so that the actual position of the feature hole 203 is aligned with the standard position, thereby accurately aligning the first charging connector and the second charging connector.

[0060] When the parallelism between the first carrier plate 101 and the second carrier plate 201 is greater than or equal to a preset threshold, acquiring the first image of the second carrier plate 201 can reduce the shooting deviation of the image acquisition device 1021.

[0061] In some embodiments of this application, the first support plate after attitude adjustment is parallel to the second support plate.

[0062] Optionally, positional deviation may also include parallelism.

[0063] The execution component 103 is also used to adjust the posture of the first support plate 101 based on the parallelism when the parallelism is lower than a preset threshold, so that the parallelism between the first support plate 101 and the second support plate 201 is greater than or equal to the preset threshold.

[0064] Optionally, this parallelism can be represented by distance, as shown in the reference. Figure 1 and Figure 4 The identification component 102 may also include multiple ranging sensors 1022, which are not in a straight line. Figure 4 Three ranging sensors 1022 are shown.

[0065] Multiple distance sensors 1022 are used to measure the distance between the first support plate 101 and the second support plate 201, and send the measured distance to the controller.

[0066] For each ranging sensor 1022, the controller determines the actual distance corresponding to that ranging sensor 1022. If the difference between any two actual distances is greater than a preset distance, it can be determined that the first support plate 101 and the second support plate 201 are not parallel, and therefore the parallelism is lower than a preset threshold. If the difference between any two actual distances is less than or equal to a preset distance, it can be determined that the first support plate 101 and the second support plate 201 are parallel, and therefore the parallelism is lower than a preset threshold.

[0067] The actual distance is within the standard distance range. Since there is a certain distance between the protective cover of the second charging connector 202 and the second carrier plate 201, if some of the ranging sensors 1022 incorrectly transmit the ranging signal to the protective cover of the second charging connector 202, while other ranging sensors 1022 transmit the ranging signal to the second carrier plate 201, then the distance measured by some ranging sensors 1022 will be significantly different from the distance measured by other ranging sensors 1022. This will result in a lower accuracy in adjusting the parallelism between the first carrier plate 101 and the second carrier plate 201.

[0068] In this embodiment, since the actual distances corresponding to different ranging sensors 1022 are all within the standard distance range, the problem of excessively large differences in the actual distances corresponding to different ranging sensors 1022 due to errors in the measurement object can be avoided, thereby ensuring the accuracy of the parallelism adjustment between the first bearing plate 101 and the second bearing plate 201.

[0069] Each ranging sensor 1022 can measure multiple distances. In one optional implementation of this application embodiment, the actual distance corresponding to each ranging sensor 1022 is determined based on the multiple distances measured by that ranging sensor 1022. For example, the actual distance can be determined by an intermediate distance group, which may include other distances besides the maximum and minimum distances among the multiple distances.

[0070] In another alternative implementation of this application, the actual distance is any one of the multiple distances measured by the corresponding ranging sensor 1022.

[0071] In some embodiments of this application, the execution component 103 is further configured to adjust the posture of the first support plate 101 based on multiple distances when the parallelism is lower than a preset threshold, so that the parallelism between the first support plate 101 and the second support plate 201 is greater than or equal to the preset threshold. As a result, the distances measured by each ranging sensor 1022 are equal, thereby making the first support plate 101 parallel to the second support plate 201.

[0072] refer to Figure 1 and Figure 7 The positioning device 100 may also include a protective cover 104, with the identification component 102 located inside the protective cover 104, which can shield from wind, rain, snow, and sunlight.

[0073] refer to Figure 8 The end face of the protective cover 104 is in contact with the end face of the box-type power supply 200. A sealed space is formed between the end face of the protective cover 104 and the end face of the box-type power supply 200.

[0074] The execution component 103 is further configured to drive the end face of the protective cover 104 to fit against the end face of the box-type power supply 200 before acquiring the positional deviation between the first support plate 101 and the second support plate 201, so as to form a sealed space between the protective cover 104 and the second support plate 201. The degree of sealing of the sealed space is greater than a degree threshold.

[0075] Optionally, the execution component 103 is further configured to drive the end face of the protective cover 104 to engage with the end face of the box-type power supply 200 before obtaining the parallelism between the first support plate 101 and the second support plate 201. (See reference) Figure 8 The execution component 103 is also located inside the protective cover 104.

[0076] refer to Figure 1 and Figure 4 The positioning device 100 further includes an illumination component 105 located on the first support plate 101, which is used to illuminate the enclosed space. For example, the illumination component 105 may be a light-emitting diode (LED).

[0077] The identification component 102 is also used to acquire a first image of the second carrier plate 201 after the lighting component 105 illuminates the enclosed space, and to acquire the positional deviation based on the first image.

[0078] When the end face of the drive protective cover 104 is attached to the end face of the box-type power supply 200, so that a nearly closed sealed space is formed between the protective cover 104 and the second carrier plate 201, a similar light environment can be created in the sealed space after illumination, thereby improving the clarity of the acquired first image and thus improving the visual positioning accuracy.

[0079] In some embodiments of this application, the lighting component 105 is used for: The enclosed space is illuminated after the parallelism between the first support plate 101 and the second support plate 201 is greater than or equal to a preset threshold. That is, the enclosed space is illuminated when the first support plate 101 and the second support plate 201 are parallel. By illuminating the enclosed space when image acquisition is required, power resources are saved while ensuring the clarity of the acquired images.

[0080] refer to Figure 7 The end face of the protective cover 104 is provided with a roller shutter door 106.

[0081] When the end face of the protective cover 104 is in contact with the end face of the box-type power supply 200, the roller shutter door 106 is in a retracted state, so that the first charging connector 301 can pass through the roller shutter door 106 and be plugged into the second charging connector 202.

[0082] When the box-type power supply 200 is not being charged, the roller shutter door 106 is in the closed state. This keeps the components inside the protective cover in a sealed space, thus achieving the purpose of sheltering from wind, rain, snow, and sunlight.

[0083] refer to Figure 3 and Figure 9 The second charging connector 202 is provided with a protective cover 204. The identification component 102 also includes an alarm component, which is used to issue an alarm message when the protective cover 204 is not opened. The alarm message is used to prompt the operator to open the protective cover 204. This avoids the problem that the protective cover 204 may be damaged due to mechanical collision caused by the actuator 103 controlling the first charging connector 301 to plug into the second charging connector 202 when the protective cover 204 is not opened.

[0084] In some embodiments of this application, the identification component 102 is further configured to acquire a second image of the second carrier plate 201 and detect whether the protective cover 204 is open based on the second image.

[0085] Optionally, the image acquisition unit 1021 is further configured to acquire a second image of the second carrier plate 201 and send the second image to the controller. The controller can compare the second image with a standard image to detect whether the protective cover 204 is open. The standard image can be, for example,... Figure 5 As shown, the protective cover 204 in the standard image is in the open state.

[0086] refer to Figure 1 , Figure 4 and Figure 6 The identification component 102 also includes a guide post 107 located on the first support plate 101, for reference. Figure 9 The second support plate 201 is provided with guide holes 205.

[0087] With the first charging connector 301 and the second charging connector 202 aligned, the guide post 107 is inserted into the guide hole 205.

[0088] With the guide post 107 inserted into the guide hole 205, the first charging connector 301 is inserted into the second charging connector 202.

[0089] The execution component 103 is used to control the guide post 107 to insert into the guide hole 205 when the first charging connector 301 and the second charging connector 202 are aligned, and then control the first charging connector 301 and the second charging connector 202 to be plugged in.

[0090] With the protective cover 204 open and the first charging connector 301 aligned with the second charging connector 202, the guide post 107 is inserted into the guide hole 205.

[0091] The actuator 103 is also used to control the guide post 107 to be inserted into the guide hole 205 when the protective cover 204 is open.

[0092] In summary, this application provides a positioning device for a marine charging connector. This device acquires the positional deviation between a first support plate and a second support plate, and adjusts the attitude of the first support plate based on the positional deviation. After the attitude adjustment, the first charging connector on the first support plate is aligned with the second charging connector. Therefore, this positioning device can automatically position the second charging connector and automatically align the first and second charging connectors. Compared to manually aligning the first and second charging connectors, this significantly improves the efficiency of aligning the first and second charging connectors.

[0098] The specific implementation process of steps 1001 to 1002 can be referred to the above-described device embodiment.

[0099] In summary, this application provides a method for positioning a marine charging connector. After obtaining the positional deviation between the first and second support plates, the method adjusts the attitude of the first support plate based on the positional deviation, aligning the first and second charging connectors on the adjusted first support plate. Therefore, this positioning device can automatically position the second charging connector and automatically align the first and second charging connectors. Compared to manually aligning the first and second charging connectors, this method effectively improves the efficiency of aligning the first and second charging connectors.
