Description

Technical Field

[0001] This invention relates to the field of power battery technology, and more specifically to a method for installing marine battery packs. Background Technology

[0002] Due to space constraints in ship battery compartments—which are typically located inside the hull where space is extremely limited—installing and moving batteries becomes very difficult, especially in confined spaces. Furthermore, ship battery compartments require good ventilation to prevent batteries from overheating. This usually necessitates the installation of ventilation equipment such as fans or ventilation ducts. However, these devices can consume a significant amount of space, further complicating battery installation.

[0003] Furthermore, installing batteries in a ship's battery compartment requires specialized tools such as cranes and forklifts. However, these tools may not be fully effective in confined spaces, thus increasing the difficulty of installation.

[0004] Marine batteries are bulky and heavy, making them unsuitable for transport. They are also expensive, increasing overall costs. Furthermore, their maintenance is complex and requires professional personnel.

[0005] Existing ships are equipped with battery compartments to meet daily energy needs, housing large battery packs. These battery compartments are characterized by limited installation space, requiring batteries to be inserted individually through narrow entrances before being assembled. Furthermore, due to the risks of wind, waves, and human-caused damage during ship operation, vibration damping and shock-absorbing devices are necessary to prevent accidental collisions and impacts between batteries, which could affect battery stability and damage the batteries.

[0006] A search revealed that CN106601958A discloses a fixing structure for a battery module. The module end plate of the battery module is fixed to a fixing beam by a limiting member, which can effectively clamp the module end plate, reduce the contact pressure between the limiting member and the module end plate, and is simple to operate, has a stable structure, good fixing effect, and strong vibration resistance.

[0007] While the aforementioned solutions all take into account battery impact protection and vibration reduction, they are not suitable for installation in confined spaces and do not solve the problem of limited battery compartment space on existing ships. Therefore, inventing a method suitable for installing marine battery packs is of great practical significance. Summary of the Invention

[0008] To address the shortcomings of existing technologies and the challenges of limited installation space and difficult installation in ship battery compartments, this invention provides a method for installing marine battery packs. The battery blocks are designed in an array arrangement, making efficient use of the battery compartment space. Positioning units that mate with the batteries are installed at the bottom of the battery compartment, facilitating overall installation and ensuring a stable connection between the batteries and the battery compartment. Simultaneously, built-in vibration dampers within the batteries provide shock absorption and protection, effectively protecting the batteries and improving the reliability and lifespan of the battery pack.

[0009] The marine battery pack installation method of the present invention modularizes the battery blocks. The entire installation process only requires repeatedly placing the limiting plate into the designated position and pushing the battery to the limiting plate, without any mechanical bolts or fasteners. The installation efficiency and reliability are high.

[0010] The technical means adopted by the present invention to solve the above problems are as follows:

[0011] A method for installing a marine battery pack is disclosed, comprising the following steps: S1. Pre-dividing the bottom of the battery compartment into battery placement areas, then placing positioning units one by one, and pre-setting the placement positions of the battery blocks; S2. Lifting the battery blocks and placing them into the battery compartment through the battery inlet; S3. Fixing the bottom of the battery blocks to the bottom of the battery compartment through the positioning units, so that there is no slippage between the battery blocks and the battery compartment; the battery blocks are fixed to form an array structure of the battery pack; S4. Installing anti-collision structures in the gaps between the array structures at the top of the battery pack, the anti-collision structures isolate and fix the battery pack to prevent the batteries from being hit.

[0012] The marine battery pack installation method of this invention combines the structure of the positioning unit, battery block, and battery compartment into a single design. The battery pack can be arranged according to the bottom structure of the battery compartment, where the battery mounting positions are pre-set at the bottom. The bottom of the battery pack rests on the track groove of the positioning unit and is secured using a limiting plate. The battery pack abuts against the bottom of the battery compartment without any other connection. The entire assembly process is simple and particularly suitable for assembling battery packs in confined spaces.

[0013] Furthermore, the battery block is a rectangular block, including a battery body and a bottom. A vibration damper is installed inside the battery body to improve the reliability and lifespan of the battery pack. The bottom of the battery block has an "I"-shaped slot, with the top of the "I"-shaped slot connecting to the battery body and the bottom of the "I"-shaped slot serving as a positioning plate. A vibration damper is installed inside the battery on the side near the top of the "I"-shaped slot. The "I"-shaped slot effectively aligns the battery block body with the track groove at the bottom of the battery compartment, facilitating the fixed connection between the limiting plate and the "I"-shaped slot and the track groove.

[0014] Furthermore, the positioning unit includes several sets of track grooves, which are connected to a limiting plate, allowing the limiting plate to slide within the track grooves and fix the bottom of the battery block and the track grooves together to position the battery block in its installation position. The multiple sets of track grooves are for effective use in conjunction with the "I"-shaped locking slots.

[0015] Furthermore, the track groove is an inverted T-shaped groove extending along the battery arrangement direction. The inverted T-shaped groove is embedded in the bottom of the battery compartment and includes a locking part and a cavity enclosed by the locking part. The width of the positioning plate of the "I"-shaped groove is equal to or slightly less than the distance between the edges of the locking parts of two adjacent track grooves.

[0016] Furthermore, the pre-divided area at the bottom of the battery compartment is composed of multiple sets of support plates, the number of which is N-1 (where N is a natural number greater than 2) of the number of track grooves; the support plates and the mounting surfaces of the snap-fit ​​parts are on the same horizontal plane; the width of the support plate is less than or equal to the difference between the width of the battery block's positioning plate and the horizontal width of the snap-fit ​​part on one side.

[0017] Furthermore, the limiting plate includes a positioning surface and a sliding surface, which are connected by a connecting rod; the size of the sliding surface is smaller than the inner size of the inverted T-shaped groove. The positioning surface is engaged with the "I"-shaped groove to lock and fix the track groove and the "I"-shaped groove into one unit.

[0018] Furthermore, the bottom of the "I"-shaped slot is coupled and fixed to the positioning surface of the limiting plate.

[0019] Furthermore, the length of the connecting rod is greater than the sum of the thickness of the positioning plate and the thickness of the snap-fit ​​part; and less than the vertical thickness from the top of the "I"-shaped slot to the inner wall of the snap-fit ​​part.

[0020] Furthermore, a limiting disk mounting groove is provided on the track groove, and the groove opening size of the limiting disk mounting groove is larger than the outer edge size of the sliding surface of the limiting card groove.

[0021] Furthermore, the anti-collision structure includes a top surface and a cross-shaped limiting portion, the thickness of which is less than or equal to the gap between the top arrays of the battery pack. The anti-collision structure is a rubber cross block, which prevents collisions between batteries and also serves to dampen vibrations and resist impacts between battery blocks.

[0022] Furthermore, a space for accommodating the top plane of the battery is provided between the top of the adjacent battery blocks and the battery compartment.

[0023] The advantages of this invention compared to the prior art are:

[0024] The battery pack installation method for this ship uses a modular design. The entire installation process only requires repeatedly placing the limiting plate into the designated position and pushing the battery to the limiting plate. There are no mechanical bolts or fasteners for connection, resulting in high installation reliability.

[0025] This method is particularly suitable for installing batteries in confined spaces. It does not increase installation costs but can effectively improve installation efficiency. Attached Figure Description

[0035] The following is in conjunction with the appendix Figure 1 - Appendix Figure 8The present invention will be further described below. The accompanying drawings are for illustrative purposes only, representing schematic diagrams rather than actual physical objects, and should not be construed as limiting the scope of this patent. To better illustrate the embodiments of the present invention, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. Example 1

[0036] The marine battery pack installation method of this embodiment includes the following steps: S1. The bottom of the battery compartment 2 is pre-divided into battery placement areas, and then the positioning units are placed one by one, and the battery block placement positions are pre-set; S2. The battery blocks are lifted and placed into the battery compartment 2 through the battery inlet 21; S3. The bottom of the battery blocks is fixed to the bottom of the battery compartment 2 through the positioning units, so that there is no slippage between the battery blocks and the battery compartment 2; the battery blocks are fixed to form an array structure of the battery pack; S4. An anti-collision structure 5 is installed in the gaps of the array structure at the top of the battery pack 1. The anti-collision structure 5 isolates and fixes the battery pack to prevent the batteries from being hit.

[0037] like Figure 1 -like Figure 6 As shown, in view of the characteristics of limited installation space and difficult installation of ship battery compartments, the space of the battery compartment is rationally utilized, and a positioning unit that cooperates with the battery is set at the bottom of the battery compartment, which makes the overall installation convenient and the battery and battery compartment are installed firmly. At the same time, the battery has a built-in vibration damper to provide vibration reduction and shock resistance, effectively protecting the battery and improving the reliability and life of the battery pack.

[0038] Battery pack 1 is set as the unit to be installed. Battery blocks of the same size are arranged and combined inside the battery compartment. Specifically, the battery compartment 2 is installed outside the battery pack 1. The battery compartment 2 provides space to accommodate batteries. A battery inlet 21 is provided on the top of the battery compartment 2. The battery inlet is generally circular or elliptical, which can facilitate the insertion of at least one battery block.

[0039] Battery pack 1 comprises multiple independent battery blocks, which can be arranged in an array, in this embodiment forming a 3×3 cuboid. The battery compartment 2 contains a positioning unit for positioning and installing the battery blocks. This positioning unit includes several sets of track grooves 3, which are connected to limiting disks 4. The limiting disks 4 slide within the track grooves 3, fixing the bottom of the battery block and the track grooves 3 together to position the battery block. In this embodiment, the ends of the track grooves 3 have an open structure, with the inner wall of the battery compartment 2 abutting against the ends of the track grooves 3. This provides positioning for the limiting disks 4 installed at the ends. The limiting disks 4 are close to or have a small gap from the inner wall of the battery compartment 2, ensuring stable installation of the entire battery block on the track grooves 3 and preventing slippage.

[0040] In this embodiment, the track groove 3 is an inverted T-shaped groove extending along the battery arrangement direction. The inverted T-shaped groove is embedded in the bottom of the battery compartment 2 and includes a snap-fit ​​part 31 and a cavity 32 surrounded by the snap-fit ​​part 31.

[0041] The positioning unit and battery pack are detachably connected. The battery block is inserted from outside the battery compartment 2 through the battery inlet 21 and fixed in the designated position on the positioning unit, isolating and securing the battery pack to prevent impact damage; a shock absorber 6 is installed inside the battery block (e.g., Figure 6 As shown in the figure, the battery frame has a built-in shock absorber 6, which can protect the battery from impact in multiple directions and has excellent shock absorption and shock resistance performance, thereby improving the reliability and life of the battery pack.

[0042] In order to facilitate the installation of the battery pack 1 and the battery compartment 2 and ensure reliable use, a slot 22 with an "I" shaped cross-section is provided at the bottom of the battery block. The top of the "I" shaped slot 22 is connected to the battery body, and the bottom of the "I" shaped slot is a positioning plate 23. A vibration damper 6 is provided inside the battery on the side near the top of the "I" shaped slot.

[0043] like Figure 3 As shown, the pre-divided area at the bottom of the battery compartment 2 is a set of support plates. The number of support plates is N-1 (N is a natural number greater than 2) of the number of track grooves 3. In this embodiment, there are 3 sets of support plates. The mounting surfaces of the support plates and the snap-fit ​​parts 31 are on the same horizontal plane. The width of the support plate is less than or equal to the difference between the width of the positioning plate 23 of the battery block and the width of the snap-fit ​​part 31 on one side in the horizontal direction.

[0044] The limiting plate 4 includes a positioning surface 41 and a sliding surface 42, which are connected by a connecting rod 43. The length of the connecting rod 43 is greater than the sum of the thickness of the positioning plate 23 and the thickness of the locking part 31, but less than the vertical thickness from the top of the "I"-shaped groove to the inner wall of the locking part 31. This design is beneficial for the stability of the fixation and the ease of installation.

[0045] Furthermore, the sliding surface 42 is a rectangular block extending from the center of the connecting rod 43 to both ends, and the size of the sliding surface 42 is smaller than the inner size of the inverted T-shaped groove. A groove is formed between the positioning surface 41 and the sliding surface 42 to facilitate the coupling and fixation of the positioning plate 23 of the "I"-shaped slot 22 with the positioning surface 41 of the limiting plate 4. In this embodiment, they are specifically fitted together.

[0046] To facilitate installation, a limiting plate mounting groove 33 is provided on the track groove 3. The opening size of the limiting plate mounting groove 33 is larger than the outer edge size of the sliding surface 42 of the limiting slot. In this embodiment, multiple limiting plate mounting grooves 33 can be provided on each track groove 3. The limiting plate 4 can be embedded in the track groove 3 at the limiting plate mounting groove 33 closest to the installation position, saving installation time.

[0047] Anti-collision blocks 5 are provided on the top of adjacent battery blocks in the battery pack, and rubber cross blocks are provided between each battery block. The anti-collision blocks 5 include a top surface 51 and a cross-shaped limiting part 52 to prevent collisions between batteries and to provide vibration reduction and shock resistance between batteries.

[0048] There is a space between the top of the adjacent battery blocks and the battery compartment to accommodate the top plane of the battery.

[0049] Since the battery compartment 2 has only one entrance, battery inlet 21, and is in a closed state, during installation, the installer stands inside the battery compartment 2 and pushes the first set of limiting discs 4 through the limiting disc mounting slot 33 to one side edge of the track groove 3. Using the hanging device, the first battery block is placed into the bottom of the battery compartment 2 to be fixed through the battery inlet 21 and pushed along the track to the first set of limiting discs 4. The limiting discs 4 are locked in the "I"-shaped slot 22 at the bottom of the battery block. Then, the second set of limiting discs 4 is placed into the track groove 3 and locked into the bottom of the battery compartment 2 on the other side of the first battery block. The installation of the second battery block is then repeated. For ease of installation, the side farther from the battery inlet 21 should be installed first. After one row is installed, the second row is installed. After the first battery block of the second row is installed, anti-collision blocks 5 can be installed on the top of the three adjacent battery blocks. The entire installation process only requires repeatedly placing the limiting discs in the designated positions and pushing the batteries to the limiting discs, without any mechanical bolts or fasteners. It can prevent accidental collisions and impacts between batteries during ship operation, which could affect battery stability and damage the batteries. Example 2

[0050] like Figures 7-8 As shown, this embodiment is largely the same as Embodiment 1, except that the end of the track groove 3 in this embodiment is in a closed state. A groove end baffle 34 is provided at the end of the track groove. The first set of limiting discs 4 is pushed to the groove end baffle 34 on one side of the track groove 3 through the limiting disc mounting groove 33. The first set of limiting discs 4 serves as the reference for the installation of the entire battery block. Another set of limiting discs 4 can be installed to fix the bottom of the battery block. The remaining installation steps are the same as in Embodiment 1.

[0051] The above are merely embodiments of the present invention, and the invention is not limited to the fields covered by these embodiments. Commonly known structures and characteristics in the solutions are not described in detail here. It should be noted that those skilled in the art can make various modifications and improvements without departing from the scope of the present invention, and these should also be considered within the scope of protection of the present invention. These modifications and improvements will not affect the effectiveness of the present invention or the practicality of the patent. The scope of protection claimed in this application should be determined by the content of its claims, and the specific embodiments described in the specification can be used to interpret the content of the claims.
