Description

Technical Field

[0001] The utility model relates to the technical field of ships, and in particular to a battery cluster rack and an energy storage system for ships. Background Art

[0002] As the International Maritime Organization sets increasingly stringent standards for ship emissions, and as oil resources gradually become depleted, internal combustion engines will gradually phase out, and green and environmentally friendly electric propulsion systems will become the future direction of ship propulsion development. The design of the energy storage system for electric ships can refer to the energy storage system of large vehicles. The energy storage system of large vehicles usually includes a cluster frame and multiple battery packs. The cluster frame is fixed on the vehicle body, and the battery pack is arranged on the cluster frame. The cluster frame usually includes a longitudinal frame and a horizontal frame arranged between the longitudinal frames. The battery pack is installed on the horizontal frame. There are limiting structures on both sides and in front and behind the battery pack to limit the battery pack, so that the battery pack is fixed in the horizontal direction, but there is no corresponding limiting structure in the longitudinal direction. Ships are different from vehicles. Ships are located on the water surface. The waves on the water surface will impact the ship and cause the ship to jump in the longitudinal direction. There is a risk of the battery pack jumping up and down. Therefore, it is necessary to improve the cluster frame structure according to the characteristics of the ship.

[0042] See also Figures 1 to 5 As shown, an embodiment of the present application provides a battery cluster frame for a ship, comprising: a plurality of longitudinal frames 1, a plurality of horizontal frames 2 and a limiting member 3. The longitudinal frames 1 are arranged in sequence and in parallel with each other. The horizontal frames 2 are arranged between the adjacent longitudinal frames 1, and the horizontal frames 2 are respectively connected to the longitudinal frames 1 on both sides. A battery cavity is formed between the two upper and lower adjacent horizontal frames 2. The limiting member 3 is arranged on the longitudinal frame 1. A limiting gap for the battery pack 7 is formed between the limiting member 3 and the horizontal frame 2. When the battery pack 7 is installed in the corresponding battery cavity, the limiting member 3 is limited to the side of the battery pack 7 away from the horizontal frame 2. The battery cluster frame of the present application is provided with a limiting member 3 that can cooperate with the battery pack 7 in the longitudinal direction to limit the longitudinal movement of the battery pack 7, thereby improving the stability and reliability of the installation of the battery pack 7 and solving the problem of insufficient longitudinal restraint of the battery pack 7 in electric ships.

[0043] It should be noted that the bottom of the battery pack has a protruding edge structure, which can be a water-cooling plate or the bottom shell of the battery. The limiting member 3 is located on the top of the edge structure and is pressed tightly against the edge structure.

[0044] In some possible implementations, multiple limiting members 3 are provided in each battery cavity, and each limiting member 3 is provided on two adjacent longitudinal frames 1. When the battery pack 7 is installed in the corresponding battery cavity, each limiting member 3 on the two adjacent longitudinal frames 1 is respectively limited to the side of the battery pack 7 facing away from the horizontal frame 2. The limiting members 3 and the horizontal frame 2 cooperate to clamp and secure the battery pack 7 in the longitudinal direction, preventing the battery pack 7 from jumping in the longitudinal direction.

[0045] In some possible implementations, the longitudinal frame 1 includes a plurality of columns 11, each of which is arranged at intervals, and the limiting member 3 is disposed on the column 11. The column 11 has a high structural strength and can be conveniently and stably assembled with the limiting member 3.

[0046] In some possible implementations, see Figure 2 and Figure 3 As shown, the stopper 3 is secured to the column 11 via a fastener 6. The stopper 3 is an elastic structure. When the battery pack 7 is installed in the battery cavity, the stopper 3 elastically presses against the battery pack 7, providing a buffering and limiting effect in the longitudinal direction. The stopper 3 can be block-shaped. The bottom surface of the stopper 3 is in contact with the battery pack 7.

[0047] In some possible implementations, a rivet nut 111 is provided on the column 11, one end of the fastener 6 passes through the stopper 3 and is threadedly connected to the rivet nut, and the other end of the fastener 6 is limited on the stopper 3. The fastener 6 may be a screw.

[0048] The battery cluster frame includes a slide member 4, which is located in the battery cavity and connected to each column 11 of the longitudinal frame 1. The slide member 4 is located between the limit member 3 and the column 11. A slide member 4 is provided on each side of the battery pack in the battery cavity, guiding the battery pack in or out of the battery cavity and limiting the position of the battery pack 7 on the left and right sides. The slide member 4 has a corresponding avoidance hole for each rivet nut 111. The fastener 6 can be threadedly connected to the rivet nut 111, and the fastener 6 essentially passes through the slide member 4.

[0049] Alternatively, see Figure 2 As shown, the slide member 4 includes a horizontal plate 41 and a vertical plate 42 connected to the horizontal plate 41, the horizontal plate 41 is supported on the horizontal frame 2, the vertical plate 42 is attached to the longitudinal frame 1, and the limit member 3 is at least partially located on the side of the vertical plate 42 away from the longitudinal frame 1.

[0050] The limiting member 3 may also adopt other structures, for example, see Figure 4 and Figure 5 As shown, in some possible embodiments, the stopper 3 includes a fixed body 31 and a rotating body 32. The fixed body 31 is connected to the column 11, and the rotating body 32 is rotatably connected to the fixed body 31. The rotating body 32 has an elastic structure. By providing the rotating body 32, when the battery pack 7 is inserted into the battery cavity and passes through the limiting gap of the battery pack 7, the rotating body 32 rotates synchronously due to the action of friction, reducing the resistance to the movement of the battery pack 7 and allowing the battery pack 7 to be smoothly installed into the battery cavity.

[0051] The fixed body 31 can be a cylinder welded to the column 11. A convex ring is provided on the side of the cylinder facing away from the column 11. The rotating body 32 is a sleeve that can be mounted on the cylinder. The convex ring has a limiting effect on the sleeve, preventing the sleeve from separating from the cylinder. Lubricating grease can be applied between the cylinder and the sleeve to reduce friction.

[0052] When the slide member 4 includes a horizontal plate 41 and a vertical plate 42 connected to the horizontal plate 41 , the vertical plate 42 may be provided with an escape opening, and the vertical plate 42 is sleeved on the outside of the fixed body 31 through the escape opening.

[0053] See also Figure 2 As shown, a rear baffle 43 may be provided at the end of the slide member 4 so that the battery pack 7 abuts against the rear baffle 43 when the battery pack 7 is pushed into the battery cavity to the limit position.

[0054] The battery cluster frame further includes a front baffle 5, which is detachably connected to the longitudinal frame 1 or the horizontal frame 2 to limit the position of the battery pack 7 in front of the battery pack 7. The front baffle 5 and the rear end plate are respectively located at the front and rear sides of the battery pack 7.

[0055] The bottom frame structure of the battery cluster rack is provided with a connection hole, and one end of a bolt can pass through the connection hole to be connected to the ship, and the cap of the bolt is limited to the bottom frame structure.

[0056] See also Figures 1 to 3As shown, the following provides an assembly process for a battery cluster rack provided by an embodiment of the present application. First, rivet nuts 111 are set on the columns 11. The slide members 4 are welded to each column 11. Avoidance holes are set on the slide members 4 corresponding to each rivet nut 111. The horizontal plate 41 of the slide member 4 is welded to the horizontal frame 2, and the vertical plate 42 is welded to each column 11. The limit members 3 are connected to each rivet nut 111 by screws. The end of the slide member 4 is integrally formed with a rear baffle 43. The battery pack 7 is pushed into the battery cavity through the entrance of the battery cavity. The horizontal frame 2 and the limit member 3 are limited to the upper and lower sides of the battery pack 7, and the two slide members 4 are limited to the left and right sides of the battery pack 7. Finally, the front baffle 5 is installed on the battery cluster rack, so that the front baffle 5 and the rear baffle 43 are respectively limited to the front and rear sides of the battery pack 7. This limits the battery pack 7 in all directions and improves the assembly structural stability of the battery pack 7.

[0057] The embodiment of the present application also provides an energy storage system, including: a battery pack 7 and the above-mentioned battery cluster rack of the ship, the battery pack 7 is installed in the battery cavity of the battery cluster rack, and in the height direction of the battery cluster rack, the battery pack 7 is limited between the horizontal frame 2 and the limiting member 3.

[0058] In some possible implementation schemes, the energy storage system includes a water cooling unit 8 and a high-voltage box 9, which are arranged on the same horizontal frame 2. The water cooling unit 8 will dissipate heat and is not suitable to be arranged on the same horizontal frame 2 as the battery pack 7. In the embodiment of the present application, the water cooling unit 8 and the high-voltage box 9 are arranged on the same horizontal frame 2, which can make full use of the space on the battery cluster rack, so that as many battery packs 7 as possible can be arranged on the battery cluster rack.

[0059] In a preferred embodiment, the water cooling unit 8 and the high-voltage box 9 are located on the topmost horizontal frame 2 or in the topmost battery cavity.

[0060] The above description is only a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technician familiar with this patent can make some changes or modifications to equivalent embodiments of equivalent changes using the technical content suggested above without departing from the scope of the technical solution of the present invention.
