Description

Technical Field

[0001] This invention relates to the field of electrical energy storage and charging technology, and in particular to a marine energy storage and charging system that facilitates safe charging. Background Technology

[0002] New energy vehicles are becoming increasingly common in people's daily lives. The mutual development trend between new energy vehicles and traditional vehicles is self-evident. As a new type of transportation tool for sea, river and lake, new energy charging boats have significant advantages over traditional ships in terms of pollution, speed and cleanliness.

[0003] However, during ship charging, problems arise such as the charging gun being forgotten (which also happens during vehicle charging) or the charging cable being excessively stretched due to wind and waves, ultimately leading to serious damage to the charging system. Therefore, it is necessary to develop a system that can meet the charging needs of ships, improve the utilization rate of energy storage systems, and enhance charging safety. Summary of the Invention

[0004] The purpose of this invention is to provide a marine energy storage charging system that facilitates safe charging, meets the charging needs of ships, and improves charging safety by providing a plug, socket, and safety wire to ensure stable charging operation of the charging gun while avoiding damage to the charging lines due to wind, waves, or forgetting to unplug the charging gun.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution: A marine energy storage and charging system that facilitates safe charging includes an energy storage station connected to a floating charging device. The floating charging device includes several charging units, each including a unit body, a charging cable, and a charging gun. One end of the charging cable is connected to the unit body, and the other end is connected to the charging gun. The charging cable also includes a plug and a socket that are connected to each other. At least one safety wire is also connected between the charging gun and the unit body, and the safety wire is shorter than the charging cable.

[0006] Furthermore, the charging cable is connected to several limiting sleeves, and a safety wire is threaded through each limiting sleeve.

[0007] Furthermore, the energy storage station is also connected to an onshore charging device, which includes several identical charging units.

[0008] Furthermore, the land-based charging device and / or water-based charging device includes a top mounting frame, to which the unit body is connected.

[0009] Furthermore, the charging gun is inserted downwards into the electric vehicle or electric boat for charging during operation, and can be detached and connected to the socket after operation. The charging cable between the charging gun and the plug has a set length.

[0010] Furthermore, a T-shaped plug is connected to one side of the charging gun, and a T-shaped slot is connected to the other side of the socket. The T-shaped plug can be inserted downwards or removed upwards from the T-shaped slot.

[0011] Furthermore, the inner side of the insert block is a trapezoid or triangle that is larger at the top and smaller at the bottom.

[0012] Furthermore, the top mounting bracket is connected to several moving modules, the output end of which is connected to the unit body and drives the unit body to move horizontally.

[0013] Furthermore, the unit body is also connected to a winding device that drives the safety line and charging cable to move up and down.

[0014] Furthermore, the land-based charging device also includes a single-story or multi-story parking garage, with the top mounting bracket of the land-based charging device connected above the corresponding floor.

[0015] In summary, the present invention has the following beneficial effects: The use of both land-based and water-based charging devices can simultaneously meet the charging needs of vehicles and ships, improving the utilization efficiency of energy storage stations. Each charging unit, with its plug, socket, and safety line, facilitates stable charging while preventing damage to the charging lines due to wind, waves, or forgetting to unplug the charging gun. In the event of a broken safety line, the charging cable can be immediately disconnected via the plug and socket, ensuring that the plug and socket are pulled apart in the direction of the pulling force, preventing the end-mounted plug and socket from failing to disengage in time due to the direction of the pulling force, thus improving charging safety. Furthermore, the charging gun is connected to the socket via a T-shaped plug, reducing the possibility of collisions with the hull or other objects during its ascent and descent, and preventing it from falling to the ground when it reaches the bottom.

[0018] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. These embodiments do not constitute a limitation of the present invention. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this application.

[0019] A marine energy storage and charging system that is easy to use and safe to charge, such as Figure 1 As shown, it includes an energy storage station, which is connected to a land-based charging device on one side and a water-based charging device on the other side. The energy storage station stores energy through one or more power generation devices and can also be connected to the power grid. The energy storage station supplies energy to the land-based charging device and the water-based charging device. Its specific energy storage principle is existing technology and will not be elaborated on here. The charging needs of vehicles and ships can be met simultaneously by land-based charging devices and water-based charging devices, thereby improving the utilization efficiency of energy storage stations. The land-based charging devices and water-based charging devices include a top mounting frame 5 and several charging units connected to the top mounting frame 5. The charging units charge the corresponding vehicles or ships. Each charging unit includes a unit body 1, which is connected to the top mounting frame 5. In this embodiment, the land-based charging device includes a single-story or multi-story parking garage. The top mounting bracket 5 of the land-based charging device is fixedly connected to the top of the corresponding floor, and it can also be replaced by an ordinary vehicle charging device. The water-based charging device also includes a bridge. The top mounting bracket 5 of the water-based charging device is fixedly connected to the bottom of the bridge. One end of the bridge is connected to the shore, and the other end is connected to the other shore / connected to the bottom of the water / suspended on the water.

[0020] like Figure 2 As shown, the charging unit also includes a charging cable 2 and a charging gun 3. One end of the charging cable 2 is connected upward to the unit body 1, and the other end is connected downward to the charging gun 3, for vehicles in the garage or ships under the bridge to use for charging. The charging cable 2 also includes a plug 21 and a socket 22 connected to each other (in this embodiment, the socket 22 is located above the plug 21). The connection direction of the plug 21 and the socket 22 is set along the charging cable 2 for easy disconnection in case of emergency. At least one safety line 4 is also connected between the charging gun 3 and the unit body 1. The safety line 4 is shorter than the charging cable 2, so that the safety line 4 can withstand tension (one end of the safety line 4 is fixed to the top mounting bracket 5, and the other end is connected to the charging gun 3. The strength of the safety line 4 is lower than the strength of the connection point of the charging gun 3, so as to facilitate the next connection after the safety line 4 is broken). If the safety line 4 is broken due to the hull undulation or forgetting to unplug the charging gun 3, the plug 21 and the socket 22 are pulled apart along the tension direction of the charging cable 2.

[0021] like Figure 2As shown, the charging cable 2 is connected to several limiting sleeves 23, and the safety wire 4 is passed through each limiting sleeve 23, so that the charging cable 2 and the safety wire 4 will not be separated too far apart; in this embodiment, the limiting sleeves 23 are only distributed on the charging cable 2 located above the socket 22, so that the safety wire 4 can be completely detached from the charging cable 2 when disconnected.

[0022] like Figure 2 As shown, in order to ensure that the charging gun 3 is not at the lowest point when idle and can be easily removed, the charging gun 3 is inserted downwards into the electric vehicle or electric boat for charging when working, and can be detached and connected to the socket 22 after working. The charging cable 2 between the charging gun 3 and the plug 21 has a set length. like Figure 2 and Figure 3 As shown, to facilitate the installation and removal of the charging gun 2 from the socket 22, a T-shaped plug 31 is connected to one side of the upper end of the charging gun 3, and a T-shaped slot 221 is connected to one side of the socket 22. The T-shaped plug 31 can be inserted downwards or removed upwards from the T-shaped slot 221. In this embodiment, for easy insertion, the inner side of the plug is a trapezoid or triangle with a larger upper side and a smaller lower side. The charging gun 2 can also be disassembled and connected through a sleeve with an outer opening or a vertical plug hole. In other embodiments, a pressure sensor or pressure switch can be connected inside the T-shaped slot 221 to sense whether the T-shaped plug 31 is inserted, so as to remind the user to connect the charging gun 2 to the socket 22 after it is pulled out. The charging gun 3 is connected to the socket 22 via the T-shaped plug 31, which reduces the possibility of the charging gun 3 colliding with the hull or other objects due to external wind or vertical movement, and also avoids the problem of the charging gun 3 falling to the ground when it descends to the bottom position.

[0023] like Figure 2 As shown, several moving modules 51 are connected in the top mounting frame 5. The output end of the moving module 51 is connected to the unit body 1 and drives the unit body 1 to move horizontally. The moving module 51 can be an existing structure such as an electric cylinder or a linear module, or it can be a self-propelled drive unit installed in the unit body 1. It can also be connected to a track or other structure on the top mounting frame 5 to guide the sliding of the unit body 1. The unit body 1 is also connected to a winding device 6 that drives the safety line 4 and the charging line 2 to move up and down. The winding device 6 can be an existing winding device structure such as a winch. The safety line 4 and the charging line 2 can be inserted into the winding drum from one end, and then pass out from the outer periphery of the winding drum before being wound. This ensures that the end of the charging line 2 connected to the energy storage station is not wound along with the winding drum. The charging line 2 can also be directly connected to the winding drum and rotated and electrically connected to the energy storage end through a rotating ring or other structure.

[0024] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within the scope of its essence and protection. Such modifications or equivalent substitutions should also be considered to fall within the protection scope of the present invention.
