[0024] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0025] Combine the following Figure 1 and Figure 2 A marine charging station according to an embodiment of the present invention is described.

[0026] The offshore charging station of the embodiment of the present invention includes a photovoltaic platform 1, a central control system 16, a charging pile 2 and a charging platform 3. Photovoltaic modules 15 are laid on the photovoltaic platform 1. The central control system 16 is installed on the photovoltaic platform 1, and the central control system 16 includes an electrically connected controller and a battery, and the controller is electrically connected to the photovoltaic module 15. The charging pile 2 is installed on the photovoltaic platform 1 and is electrically connected to the battery. The charging platform 3 is installed on the photovoltaic platform 1 and can limit the components to be charged.

[0027] According to the offshore charging station of the embodiment of the present invention, the controller regulates and manages the electric energy converted by the photovoltaic module 15 to ensure that it is connected to the battery with a stable and appropriate voltage and current to realize charging of the battery. Among them, by electrically connecting the battery to the charging pile 2, it is possible to charge the component to be charged through the charging pile 2. If the component to be charged needs to be charged, the component to be charged is placed on the charging platform 3 and limited, so that the charging interface thereon can be reliably connected to the charging pile 2 to ensure reliable charging of the component to be charged. This setting effectively utilizes the electric energy stored in the battery, reduces the power supply cycle and cost of the photovoltaic platform 1, and at the same time, the component to be charged does not need to return to land for charging, which effectively increases the travel and working range of the component to be charged.

[0028] It should be noted that the central control system 16 also includes an electrically connected rectifier and inverter, the rectifier is electrically connected to the photovoltaic module 15, and the inverter is electrically connected to the charging pile 2, that is, the components to be charged are charged using alternating current. In addition, the components to be charged include but are not limited to boats, drones, and batteries removed therefrom.

[0029] In some embodiments, Figure 1 As shown, the photovoltaic platform 1 includes a lower frame 12, a column and an upper frame 11 which are connected in sequence from bottom to top, a float 14 is provided on the lower frame 12, the charging pile 2 is installed on the column or the upper frame 11, the charging platform 3 is installed on the column or the upper frame 11, and the central control system 16 is arranged at the center position of the upper frame 11.

[0030] That is, multiple photovoltaic modules 15 are arranged around the central control system 16, and this arrangement does not cause the distance between the farthest photovoltaic module 15 and the central control system 16 to be too large, thereby increasing the difficulty of wiring. At the same time, the charging pile 2 is installed on the column or the upper frame 11 to ensure that both are above the sea surface by a certain distance, further ensuring its sealing reliability before and after use.

[0031] Specifically, a float 14 is also provided at the lower end of the column to effectively ensure the floating reliability of the photovoltaic platform 1 at sea. The central control system 16 also includes a housing, and the controller, battery and other components of the central control system 16 are all located in the housing.

[0032] In some embodiments, the charging pile 2 includes a housing, an automatic cord reel, and a charging gun. The housing is mounted on the column and located between the lower frame 12 and the upper frame 11. The automatic cord reel is mounted in the housing, and a charging cord is wound in the automatic cord reel, one end of the charging cord is electrically connected to the battery, and the charging gun is electrically connected to the other end of the charging cord.

[0033] The shell ensures the waterproof sealing of the charging gun before use. The setting of the automatic cord reel ensures that the volume of the shell is not increased while increasing the length of the charging cable, so as to effectively improve the convenience of docking the charging gun with the charging interface on the component to be charged in complex marine environments.

[0034] Specifically, when components to be charged of different volumes are confined to the charging platform 3, the distance between the charging interface thereon and the shell of the charging pile 2 is different. The charging cable wound by the automatic cable reel ensures that the charging gun has a larger charging range and can complete the charging of components to be charged of different volumes. When using the charging gun, you only need to pull the charging gun to pull the charging cable out of the automatic cable reel, and it will be automatically locked after being pulled out to avoid automatically pulling the charging gun back and affecting the docking reliability with the charging interface. When charging is completed, you only need to pull the charging gun again, and the exposed charging cable can be automatically retracted into the automatic cable reel. The specific structure of the automatic cable reel is the same as the prior art and will not be repeated here.

[0035] In some embodiments, Figure 1 and Figure 2 As shown, there are multiple columns including a central column, an intermediate column and an edge column 13. There are multiple intermediate columns and they are arranged at intervals along the circumference of the central column. There are multiple edge columns 13 and they are arranged at intervals along the circumference of the central column. The charging platform 3 includes a U-shaped frame 31, a positioning pile and a buffer 32. The U-shaped frame 31 is connected to the edge column 13. The U-shaped frame 31 forms a U-shaped groove with an opening facing outward and extending in the height direction. The component to be charged is suitable for entering the U-shaped groove through the opening. The buffer 32 is arranged on the inner wall surface of the U-shaped groove, and the positioning pile is arranged above the U-shaped frame 31.

[0036] The U-shaped frame 31 is connected to the edge column 13 to reduce the difficulty of installing the U-shaped frame 31 on the photovoltaic platform 1. Taking the boat as an example, the boat drives into the U-shaped groove and ties the mooring rope on it to the fixed column 33 to complete the reliable mooring of the boat and prevent it from drifting randomly during the charging process and affecting the reliability of the electrical connection with the charging gun. Among them, the design of the U-shaped groove effectively prevents the boat from moving left and right, front and back, and the setting of the buffer 32 also effectively prevents the boat from rigidly colliding with the U-shaped frame 31 and causing damage to the boat.

[0037] Specifically, when there are multiple charging platforms 3, the sizes of the U-shaped frames 31 in different charging platforms 3 can be set to be different to ensure reliable positioning of boats of different volumes.

[0038] In some embodiments, the buffer member 32 includes a rubber pad laid on the inner wall surface of the U-shaped groove, so as to effectively reduce the manufacturing and installation costs of the buffer member 32 .

[0039] Specifically, the rubber pad can be attached to any position of the inner wall surface of the U-shaped groove, and the rubber pad can be fastened to the U-shaped frame 31 by means of screws or rivets.

[0040] Alternatively, the buffer member 32 includes a spring and a flexible block, wherein a first end of the spring is connected to the inner wall surface of the U-shaped groove, and a second end of the spring is connected to the flexible block.

[0041] The boat located in the U-shaped groove is in direct contact with the flexible block, and the impact between the U-shaped frame 31 and the boat can be offset by compressing and deforming the spring.

[0042] The flexible blocks include but are not limited to structures such as wooden blocks, rubber blocks, plastic blocks, etc. that can undergo flexible deformation.

[0043] In some embodiments, the offshore charging station further comprises an energy storage cabinet and an energy storage battery. The energy storage cabinet is mounted on the column and located between the upper frame 11 and the lower frame 12. The energy storage cabinet is provided with a plurality of mounting slots. The energy storage battery corresponds to the mounting slot one by one. The energy storage battery can be detachably mounted in the mounting slot and electrically connected to the storage battery.

[0044] That is, the storage battery can charge multiple energy storage batteries in the energy storage cabinet. When the component to be charged needs to be charged, the energy storage battery can be directly removed to replace the fully charged energy storage battery in the installation slot, thereby realizing the rapid replacement of the component to be charged. The depleted energy storage battery can be placed in the vacant installation slot to complete the charging of the energy storage battery.

[0045] Specifically, taking a boat as an example, the personnel on the boat can remove one or more energy storage batteries on the boat after the boat is moored, and then remove an equal number of energy storage batteries from the installation slots and install them on the boat, and then place the removed energy storage batteries in the installation slots, thereby completing the battery replacement operation of the boat with high efficiency.

[0046] In some embodiments, the charging platform 3 includes a support plate, a locking member, and a driving device. The support plate is mounted on the side of the upper frame 11, and the charging pile 2 includes a charging gun movably connected to the support plate. The locking member is mounted on the support plate and is used to lock the component to be charged parked on the support plate. The driving device is mounted on the support plate and is connected to the charging gun in a transmission manner. The driving device is used to drive the charging gun to dock with the charging interface on the component to be charged.

[0047] For unmanned components to be charged, when the components to be charged are locked on the support plate, the driving device drives the charging gun to move to automatically dock with the charging interface on the components to be charged, thereby realizing automatic charging of the components to be charged. After charging is completed, the driving device drives the charging gun to detach from the charging interface and reset to the initial position, waiting for the next charging operation on the components to be charged.

[0048] Specifically, when the charging gun is in the initial position, the muzzle of the charging gun is closed to ensure the waterproof sealing of the charging gun and improve its service life in complex marine environments.

[0049] In some embodiments, the charging platform 3 further includes a sealing cover and an elastic member, the sealing cover and the support plate are pivotally connected between a first position and a second position, the sealing cover at the first position and the support plate surround a sealed cavity, the elastic member connects the sealing cover and the support plate, and the elastic member presses the sealing cover toward the first position. The charging gun is slidably connected to the support plate, and the charging gun has a sealing position located in the sealed cavity and a use position partially protruding outside the sealed cavity.

[0050] That is, when the charging gun needs to be used, the charging gun moves under the drive of the driving device, and the charging gun pushes open the sealing cover to expose outside the sealed cavity, so as to achieve docking with the charging interface of the component to be charged. When charging is completed, the charging gun retracts into the sealed cavity, and the sealing cover automatically retracts under the action of the elastic member to achieve the sealing of the sealed cavity, thereby ensuring the waterproof sealing performance of the charging gun.

[0051] Specifically, the driving device is a push rod motor.

[0052] In some embodiments, the battery is electrically connected to the charging pile 2 through a transmission cable. A through hole extending in the height direction is provided at the center of the upper frame 11, and the transmission cable passes through the through hole and is partially located below the upper frame 11. The transmission cable located below the upper frame 11 is connected to the upper frame 11 through a plurality of clamps or tie bands.

[0053] The transmission cables are hidden under the upper frame 11 to prevent the transmission cables from being directly exposed to the sun and affecting their service life, and also effectively prevent the transmission cables from blocking the photovoltaic components 15 and affecting the power generation efficiency of the photovoltaic components 15.

[0054] In some embodiments, there are multiple charging piles 2 and they are arranged at intervals along the circumference of the photovoltaic platform 1 , and there are multiple charging platforms 3 and they are arranged at intervals along the circumference of the photovoltaic platform 1 .

[0055] Therefore, a photovoltaic platform 1 can charge multiple components to be charged at the same time, effectively improving the charging function of the offshore charging station, and can also consume the electric energy in the battery more quickly, avoiding the loss of electric energy generated by the photovoltaic component 15.
