Description

Technical Field

[0001] This invention relates to a rotary marine battery rack installation system and its working method, belonging to the field of marine battery installation technology. Background Technology

[0002] With the widespread application of electric propulsion technology in ships, batteries, as the main energy storage and / or power supply equipment for electric propulsion vessels, have also been widely used. However, for small, purely electric propulsion vessels, due to their narrow beam and depth (i.e., the distance between the deck and the bottom of the hull), which is mostly between 1.2m and 1.8m, the limited space leads to the following difficulties in the installation, maintenance, or replacement of batteries:

[0003] (1) If the batteries are pre-installed on the battery rack and then hoisted into the cabin for installation, on the one hand, the battery rack cannot be welded to the hull structure with an open flame (open flame may cause the batteries to explode or deflagrate); on the other hand, if the battery rack is installed with fasteners such as bolts, the space between each battery rack is small, and it is difficult to tighten the bolts of the battery racks that are put in later, unless enough width is left between each row of battery racks for personnel to operate, but this will reduce the other usable area of ​​the cabin and cause unnecessary space occupation.

[0004] (2) If the empty battery racks are installed in the cabin first, and then the batteries are installed in the battery racks, although the battery rack installation method is more convenient than the previous method (there are no batteries to obstruct the view, you can go around the battery rack to tighten the bolts, and then load the batteries. After the batteries are installed in the innermost row of battery racks, the second row of battery racks and batteries are installed), there are still problems: due to the small space in the cabin, it is not possible to use equipment to move the batteries (each battery can weigh up to 120kg). It is necessary to frequently bend over and move the batteries to the battery racks by manpower, which is labor-intensive and poses a safety hazard. It is easy to cause physical injury to the installers (especially lumbar muscle strain and cervical spine strain). Moreover, sufficient width for personnel to operate is still required between each row of battery racks.

[0005] To reduce ship weight and facilitate the handling of battery racks, the battery racks used on board are generally made of aluminum alloy. However, when these racks are connected to the hull with steel bolts, electrochemical corrosion is likely to occur, causing damage to the aluminum alloy racks and making it difficult for the racks and the batteries on them to remain stable.

[0006] The same problems exist when batteries need to be replaced or repaired. Therefore, there is an urgent need for a marine battery rack installation system that can be installed quickly and saves time and manpower to solve the above technical problems. Summary of the Invention

[0007] To address the aforementioned technical problems, the present invention aims to provide a rotary marine battery rack installation system and its operating method. Through the cooperation of a support mechanism, a rotating mechanism, a driving mechanism, and a load-bearing mechanism, the system enables the pre-installation and locking of batteries, saving manpower and enabling rapid battery loading into the compartment, thus saving time and improving battery installation efficiency.

[0008] The technical problem to be solved by this invention is achieved by the following technical solution:

[0009] A rotary marine battery rack mounting system is installed inside the ship's cabin, including a support mechanism, a rotating mechanism, a drive mechanism, and a load-bearing mechanism.

[0010] A hatch is provided above the cabin;

[0011] The cabin is equipped with a support mechanism, on which a rotating mechanism is mounted. The rotating mechanism is equipped with multiple support mechanisms for supporting the battery rack. The drive end of the drive mechanism is connected to the rotating mechanism.

[0012] The drive mechanism drives the rotating mechanism and multiple supporting mechanisms to rotate and align them sequentially with the hatch. The battery rack enters through the hatch and is installed sequentially within the supporting mechanisms.

[0013] As a preferred example, the battery rack mounting system further includes a locking mechanism, with at least one locking mechanism provided at the bottom of each of the support mechanisms, the locking mechanism being used to lock or unlock the battery rack located inside the support mechanism.

[0014] As a preferred example, the support mechanism includes a chassis frame, a lower bearing is provided at the center of the chassis frame, a deck is provided above the cabin, and an upper bearing is provided below the deck; the lower bearing is aligned with the upper bearing; and a number of ball bearings are embedded in the chassis frame.

[0015] As a preferred example, the rotating mechanism includes a rotating shaft, a bearing plate is fixed below the rotating shaft, the bearing plate is disposed above the balls, and the two ends of the rotating shaft are respectively connected to an upper bearing and a lower bearing.

[0016] As a preferred example, the driving mechanism includes a driver, a rack, and a gear. The gear is fixed to the bottom end of the rotating shaft, and the gear is meshed with the rack. The driving end of the driver is connected to the rack.

[0017] As a preferred example, each of the bearing mechanisms includes a perforated square box, and multiple perforated square boxes are arranged in a ring above the rotating mechanism.

[0018] As a preferred example, the battery rack is provided with four support legs at the bottom, and the bottom of the perforated square box is provided with a locking mechanism. The locking mechanism includes blind tubes with electric heating modules respectively provided at the four corners of the bottom of the perforated square box. The blind tubes are filled with thermoplastic resin, and multiple electric heating modules are evenly distributed on the outer peripheral wall of each blind tube and around the upper part of the blind tube near the opening, and are all controlled by a microcontroller.

[0019] As a preferred example, the upper bearing is connected to the deck via a connecting plate, and an electrical junction box is fixed on the connecting plate. The electrical junction box is equipped with a power socket and several battery lead adapter terminals.

[0020] As a preferred example, the battery rack has multiple shelves inside, the shelves are provided with heat insulation layers, and the upper part of the battery rack is provided with several bolt holes, which correspond one-to-one with the bolt holes provided on the upper part of the perforated square box.

[0021] A method for using the rotary marine battery rack mounting system described above to install a battery rack into a ship's hold includes the following steps:

[0022] (1) Pre-installed battery

[0023] Place multiple batteries into the first battery rack beforehand and connect them, leaving the lead wires exposed.

[0024] (2) Centering hatch of the perforated square box

[0025] Open the hatch, start the drive mechanism to drive the rotating mechanism to rotate, align the perforated square box on the rotating mechanism with the hatch, and then lock the drive mechanism;

[0026] (3) Open the locking mechanism

[0027] The electric heating module in the first perforated square box is activated and placed in melting mode to heat the blind tube, causing the thermoplastic resin inside the blind tube to melt.

[0028] (4) Battery rack installed in the compartment

[0029] The first battery rack, which contains multiple batteries, is hoisted in from the hatch, with the supports of the battery rack inserted into the blind tubes of the perforated square box.

[0030] (5) Battery rack locking

[0031] Once the preset melting temperature and melting time are reached, the electric heating module, under the control of the microcontroller, switches to solidification mode, stops supplying power to each blind tube in the first perforated box, and allows the molten resin to cool and solidify, thus fixing the bottom of the first battery rack. At the same time, the battery rack is connected to the perforated box with bolts, thus fixing the upper part of the first battery rack. Once room temperature is reached, the electric heating module, under the control of the microcontroller, switches to drying mode. During ship operation, the electric heating module will be repeatedly activated according to the preset working time interval, preset temperature, and drying time to appropriately heat the blind tubes at a temperature far below the resin melting point, in order to remove the moisture present at the opening of the blind tube (because the resin shrinks after solidification, some metal at the opening of the blind tube may be exposed to the humid marine atmosphere due to the shrinkage of the resin, or moisture may condense and remain on the surface of the resin that has dented due to shrinkage. Therefore, by heating the blind tube, the air around the blind tube is heated, thereby accelerating the evaporation of the surrounding moisture).

[0032] (6) Wiring

[0033] Connect the lead wires extending from the battery rack to the corresponding lead wire adapter terminals in the junction box.

[0034] (7) Subsequent battery rack installation;

[0035] Repeat the loading action of the first battery rack to complete the loading of each battery rack in sequence.

[0036] Compared with the prior art, the present invention brings the following beneficial effects:

[0037] Labor saving: The automated rotary battery rack installation system, through the cooperation of the support mechanism, rotation mechanism, drive mechanism and load-bearing mechanism, reduces the need for manual operation, improves work efficiency and reduces labor costs.

[0038] Pre-installed racks: Batteries can be pre-installed in battery racks at the battery factory, which allows the loading process to be completed quickly in the shipyard, saving time and improving overall production efficiency.

[0039] Using thermoplastic resin: The ability of thermoplastic resin to repeatedly melt and solidify is utilized to fix the bottom of the battery rack. This method not only avoids the manual labor of installing fasteners in confined spaces, but also increases friction by reinforcing the contact surface between the resin and the component through threads, thereby improving the stability and reliability of the fixing effect and facilitating corrosion resistance.

[0040] The system design of this invention is simple and ingenious. By using ball bearings, it can simultaneously bear loads and reduce frictional resistance, thereby reducing power consumption. The structure is simple and ingenious. Attached Figure Description

[0058] Example:

[0059] refer to Figure 1 The present invention provides a rotary marine battery rack 40 installation system for quickly installing the battery rack 40 in the cabin. It mainly consists of a support mechanism, a rotating mechanism, a drive mechanism and a load-bearing mechanism.

[0060] like Figure 1 As shown, a rotary marine battery rack 40 installation system is installed inside the cabin. Above the cabin is a deck with a hatch that can be opened and closed to facilitate the installation of the battery rack 40 into the cabin.

[0061] A support mechanism is installed above the bottom of the cabin, and a rotating mechanism is installed on the support mechanism. The rotating mechanism is equipped with multiple support mechanisms for supporting the battery rack 40. The drive end of the drive mechanism is connected to the rotating mechanism.

[0062] The drive mechanism drives the rotating mechanism and multiple load-bearing mechanisms to rotate and align them sequentially with the hatch. The battery rack 40 enters through the hatch and is installed sequentially within the load-bearing mechanism.

[0063] For details, please refer to Figures 1-3The support mechanism consists of a chassis frame 10, an upper bearing 12, a lower bearing 11, and several ball bearings 13. The chassis frame 10, which is the foundation of the entire support mechanism, is disc-shaped. It is fixed to the bottom of the hull via multiple support legs, providing a stable foundation for the entire support mechanism. These support legs are fixed below the chassis frame 10 and connected to the bottom of the hull. These support legs support the entire chassis frame 10, ensuring a secure connection between the chassis frame 10 and the bottom of the hull. The lower bearing 11 is located at the center of the chassis frame 10, and the upper bearing 12 is fixed below the deck at the top of the hull. The lower bearing 11 is aligned with the upper bearing 12, and both the upper bearing 12 and the lower bearing 11 are rolling bearings, providing support for the rotating mechanism. Several ball bearings 13 are embedded in the upper part of the chassis frame 10. These ball bearings 13 not only help provide load-bearing capacity but also reduce frictional resistance between the chassis frame 10 and other components. The design of the ball bearings 13 contributes to the smooth movement and stability of the support mechanism.

[0064] refer to Figure 1 and Figure 4 The rotating mechanism includes a rotating shaft 20, with a support plate 21 fixed below it. The support plate 21 is positioned above the balls 13. The two ends of the rotating shaft 20 are connected to an upper bearing 12 and a lower bearing 11, respectively. The rotating shaft 20 is the central axis of the entire rotating mechanism and is the main component responsible for supporting and rotating it. The support plate 21, a disc-shaped structure similar to the chassis frame 10, is fixed below the rotating shaft 20 and serves to support the battery rack 40 in the system. The balls 13 are positioned above the support plate 21 and are the contact points between the support plate 21 and the chassis frame 10. The balls 13 help reduce friction between the support plate 21 and other components, thereby reducing power consumption.

[0065] The two ends of the rotating shaft 20 are connected to the upper bearing 12 and the lower bearing 11, respectively. These two bearings support and stabilize the rotating shaft 20, enabling the entire rotating mechanism to rotate smoothly.

[0066] refer to Figure 3The drive mechanism includes a driver, a rack 30, and a gear 31. Gear 31 is fixed to the bottom end of the rotating shaft 20 and meshes with the rack 30. The drive end of the driver is connected to the rack 30. The driver is the core component of the entire drive mechanism and is preferably an electric actuator (not shown). The electric actuator is fixed inside the cabin and can provide propulsion using electricity to drive the rack 30 and gear 31. The rack 30 is a straight bar with teeth, connected to the drive end of the driver. When the driver operates, it pushes or pulls the rack 30. Gear 31 is fixed to the bottom end of the rotating shaft 20 and meshes with the rack 30. The function of gear 31 is to convert the linear motion from the driver into rotational motion, thereby affecting the movement of the rotating shaft 20 and the entire support mechanism. Through this drive mechanism, the driver pushes and pulls the rack 30, causing the gear 31 to rotate, thus driving the rotation of the rotating shaft 20 and the support mechanism. The use of an electric actuator makes this drive mechanism more intelligent and automated. The electric actuator can provide highly precise linear motion control. By adjusting the movement of the electric actuator, precise position control of the battery rack 40 can be achieved, ensuring accuracy during installation. Electric actuators are typically compact and space-saving. This is highly advantageous for loading operations in confined ship cabins, especially given limited space. Furthermore, electric actuators offer faster response than other actuators, facilitating quick rotation of the load-bearing mechanism into position.

[0067] refer to Figures 4-5 Each support mechanism includes an openable square box 22, and multiple openable square boxes 22 are arranged in a ring above the rotating mechanism. Each support mechanism is a structure for supporting and accommodating the battery rack 40. The openable square box 22 is part of the support mechanism and is a box or enclosure structure with an opening. Its design allows the legs 41 or other parts of the battery rack 40 to be inserted into it, thereby realizing the installation and fixation of the battery rack 40.

[0068] Multiple perforated square boxes 22 are arranged in a ring above the rotating mechanism. Multiple such perforated square boxes 22 are fixed above the bearing plate 21 of the rotating mechanism, and they are arranged in a ring or circular manner.

[0069] refer to Figure 5 The battery rack 40 mounting system also includes a locking mechanism, with at least one locking mechanism provided at the bottom of each support mechanism. The locking mechanism is used to lock or unlock the battery rack 40 located inside the support mechanism.

[0070] The battery rack 40 has four support legs 41 at its bottom, and the bottom of the perforated square box 22 has a locking mechanism. The locking mechanism includes blind tubes 23 with electric heating modules respectively set at the four corners of the bottom of the perforated square box 22. The blind tubes 23 are filled with thermoplastic resin. Multiple electric heating modules 24 are evenly distributed on the outer peripheral wall of each blind tube and around the upper part of the blind tube near the opening, and are all controlled by a microcontroller.

[0071] The locking mechanism is used to lock or unlock the battery rack 40 located inside the support mechanism. Each support mechanism has at least one locking mechanism at its bottom. In this embodiment, the battery rack 40 has four legs 41 at its bottom to provide additional support and stability, ensuring the correct position of the battery rack 40 inside the support mechanism. The electric heating module 24 and the blind tubes 23 are part of the locking mechanism and are located at the four corners of the bottom of the perforated square box 22. Each blind tube 23 contains thermoplastic resin, which is a key component of the locking mechanism. When a heat source is applied, the thermoplastic resin melts, allowing the locking mechanism to release its locked state, facilitating the installation or unlocking of the battery rack 40. The heating cables of all the blind tubes 23 within each perforated square box 22 are bundled together and connected to the junction box 14 for power supply.

[0072] Preferably, the inner diameter of the blind tube 23 is larger than the outer diameter of the support leg 41 of the battery holder 40. The blind tube 23 is provided with an internal thread, and the support leg 41 is provided with an external thread. The support leg 41 is inserted into the blind tube 23, and the thread is used to increase the friction between the two and the thermoplastic resin.

[0073] The use of thermoplastic resin to fix the battery rack 40 and the perforated square box 22 has the following advantages compared to other fixing methods:

[0074] (1) Adaptable to confined spaces: The method of fixing with thermoplastic resin does not require a large number of fasteners or complex fixing structures, so it is more suitable for limited spaces, especially when traditional fasteners cannot be used.

[0075] (2) Simplified installation process: The properties of thermoplastic resin make the fixing process relatively simple. Fixing is achieved by heating the resin to melt it and then cooling and solidifying it. Compared with traditional bolts, nuts, and other structures, this fixing method can reduce the number of procedures and steps, and improve installation efficiency.

[0076] (3) Reusability: Thermoplastic resin has the property of being able to be repeatedly melted and solidified. When it is necessary to replace or adjust the battery rack 40, it can be relatively easy to disassemble and re-fix by reheating, melting and re-curing, which increases flexibility and maintainability.

[0077] (4) Reduced Corrosion Risk: Traditional metal fasteners are susceptible to corrosion, especially in marine environments. Using thermoplastic resin for fastening reduces the use of metal components. Furthermore, the battery rack 40 is typically made of aluminum alloy, and the perforated square box 22 is generally made of steel, both of which are prone to electrochemical corrosion. Thermoplastic resin can isolate these components and prevent water / moisture intrusion, thus avoiding corrosion and reducing safety and reliability issues caused by corrosion.

[0078] Specifically, in humid environments, especially the humid atmosphere of the ocean, electrochemical corrosion can occur between aluminum alloys and steel structures. Electrochemical corrosion is a special form of metal corrosion, and the presence of moisture connecting the metals with a potential difference is a sufficient condition for its occurrence. When moisture connects the two metals, the potential difference between them makes one metal more susceptible to oxidation and corrosion, while the other is more easily reduced. In this case, the use of thermoplastic resin can form an insulating layer between the two metals, reducing the contact area where moisture connects them, thereby slowing down electrochemical corrosion. Furthermore, waterproofing and sealing are two important properties of thermoplastic resin. First, when molten, it can evaporate water around the blind tube 23 and the support, eliminating moisture between them. Second, the molten resin fills between each thread, and after solidification, it forms an effective waterproof and sealing layer at each thread, preventing water / moisture from entering between the blind tube 23 and the support. This plays a crucial role in preventing the intrusion of moisture and water vapor in the marine environment. Third, because thermoplastic resin is insoluble in water, once the resin solidifies, external water cannot dissolve it and enter the space between the blind tube 23 and the support leg. Therefore, it can provide long-term and effective resistance to corrosion. Through resin isolation, resin melting to remove moisture, and resin solidification to isolate external moisture, thermoplastic resin can reduce the risk of corrosion and increase the lifespan of metal parts.

[0079] (5) Improve the stability and reliability of the fixation: After solidification, thermoplastic resin forms a strong connection, which can provide relatively stable support. In addition, by introducing designs such as threads into the thermoplastic resin, the contact surface with other components can be increased, and the friction can be improved, thereby enhancing the stability and reliability of the fixation.

[0080] The upper bearing 12 is connected to the deck via a connecting plate. A junction box 14 is fixed to the connecting plate, containing the circuitry for the electric heating module and several battery lead adapter terminals. The connecting plate is a connecting structure that links the upper bearing 12 to the deck of the ship's cabin. The upper bearing 12 is connected to the deck of the ship's cabin via the connecting plate. This connection method helps to provide support and fixation for the upper bearing 12, ensuring it remains firmly in place within the installation system. The junction box 14 is a housing for the electrical components fixed to the connecting plate. It is an enclosed structure that houses the electrical equipment. Several battery lead adapter terminals are located within the junction box 14. These terminals are used to connect the battery leads of each rack and the leads of each rotary marine battery rack installation system, connecting the batteries according to the design scheme to the overall system circuitry.

[0081] refer to Figure 6 and Figure 7 The battery rack 40 is a metal component. The battery rack 40 has multiple shelves inside, and the shelves are provided with heat insulation layers. The heat insulation layers prevent the battery from directly contacting the battery rack 40. The upper part of the battery rack 40 is provided with several bolt holes, which correspond one-to-one with the bolt holes on the upper part of the perforated square box 22, so as to fix the battery rack 40 from the top.

[0082] The present invention also provides a method for using the above-mentioned rotary marine battery rack 40 installation system to install the battery rack 40 into the ship's cabin, comprising the following steps:

[0083] (1) Pre-installed battery

[0084] Multiple batteries are pre-placed in the first battery rack 40 and wired, with lead wires left out;

[0085] (2) 22 pairs of hatches in the perforated square box

[0086] Open the hatch, start the drive mechanism to drive the rotating mechanism to rotate, align the perforated square box 22 on the rotating mechanism with the hatch, and then lock the drive mechanism;

[0087] (3) Open the locking mechanism

[0088] The electric heating module in the first perforated square box 22 is activated and placed in melting mode to heat the blind tube 23, causing the thermoplastic resin inside the blind tube 23 to melt.

[0089] (4) Battery rack 40 enters the compartment

[0090] The first battery rack 40, which is equipped with multiple batteries, is hoisted in from the hatch, and the legs 41 of the battery rack 40 are all inserted into the blind tubes 23 of the perforated square box 22.

[0091] (5) Battery rack 40 lock

[0092] Once the preset melting temperature and melting time are reached, under the control of the microcontroller, the electric heating module switches to solidification mode, stops supplying power to each blind tube 23 in the first perforated square box 22, and allows the molten resin to cool and solidify, thus fixing the bottom of the first battery rack 40; at the same time, the battery rack 40 is connected to the perforated square box 22 with bolts, thus fixing the upper part of the first battery rack 40; once room temperature is reached, under the control of the microcontroller, the electric heating module 24 switches to drying mode. During ship operation, the electric heating module 24 will be repeatedly started according to the preset working time interval, preset temperature, and drying time to appropriately heat the blind tubes 23 at a temperature far below the resin melting point in order to remove the moisture present at the opening of the blind tubes;

[0093] (6) Wiring

[0094] Connect the lead wires extending from the battery rack to the corresponding lead wire adapter terminals in the junction box.

[0095] (7) Subsequent battery rack 40 is installed in the compartment

[0096] Repeat the loading action of the first battery rack 40 as described above, and complete the loading of each battery rack 40 in sequence.

[0097] Specifically, the steps for installing the battery into the compartment are as follows:

[0098] 1) Battery rack 40 enters the cabin

[0099] Open the hatch, start the electric push rod, drive the rack 30 and gear 31, so that the rotating shaft 20 drives the bearing plate 21 to rotate, thereby aligning the first perforated square box 22 with the hatch, and then lock the electric push rod; then start the electric heating module in the first perforated square box 22 and put it in melting mode to heat the blind tube 23, so that the thermoplastic resin inside melts.

[0100] Meanwhile, the batteries are placed in the first battery rack 40 outside the cabin, and the batteries in the rack are connected according to the designed circuit, leaving the lead wires (this can also be done in the factory before loading); then the first battery rack 40 is hoisted in from the hatch, and its legs 41 are inserted into the blind tubes 23 of the perforated square box 22.

[0101] Once the preset melting temperature and melting time are reached, the electric heating module switches to solidification mode under the control of the microcontroller, stopping the power supply to each blind tube 23 in the first perforated box 22, so that the molten resin can cool and solidify, thereby fixing the bottom of the first battery rack 40. At the same time, the battery rack 40 is connected to the perforated box 22 with bolts to fix the upper part of the first battery rack 40. Once room temperature is reached, the electric heating module 24 switches to drying mode under the control of the microcontroller. During ship operation, the electric heating module 24 will be repeatedly started according to the preset working time interval, preset temperature, and drying time to appropriately heat the blind tubes 23 at a temperature far below the resin melting point to remove the moisture present at the opening of the blind tubes.

[0102] Connect the lead wires extending from the battery rack to the corresponding lead wire adapter terminals in the junction box.

[0103] By repeating the loading action of the first battery rack 40 in sequence, the loading of each battery rack 40 can be completed in sequence.

[0104] 2) Battery rack 40 exits the cabin

[0105] Open the hatch, start the electric push rod, drive the rack 30 and gear 31, so that the rotating shaft 20 drives the bearing plate 21 to rotate, thereby aligning the first perforated box 22 with the hatch, and then lock the electric push rod; then start the electric heating module 24 in the first perforated box 22 to heat the blind tube 23, so that the thermoplastic resin inside melts.

[0106] At the same time, remove the bolts connecting the battery rack 40 and the perforated square box 22, and remove the external lead wire of the battery in the battery rack 40 from the junction box 14; after the thermoplastic resin melts, remove the battery rack 40 from the compartment and turn off the electric heating module 24.

[0107] By repeating the aforementioned exit action of the first battery rack 40, the exit of each battery rack 40 can be completed in sequence.

[0108] 3) Because the thermoplastic resin is in a molten state, some resin will be carried out when the battery rack 40 is removed. Therefore, some thermoplastic resin needs to be replenished after removing the battery rack 40. The replenishment process is as follows: Before reinstalling the battery rack 40 (at this time, the resin in the blind tube 23 is in a solidified state), rotate the empty perforated box 22 to the hatch and lock it. Then open the hatch cover, and personnel hang the rope ladder at the hatch, enter the bottom of the perforated box via the rope ladder, and add an appropriate amount of thermoplastic resin to each blind tube 23. Afterwards, personnel exit the hatch via the rope ladder and remove the rope ladder.

[0109] 4) Multiple rotary marine battery rack mounting system

[0110] If there are multiple rotary marine battery rack 40 installation systems, depending on the size of the ship's cabin space, several can be arranged in one or more rows. Each row shares a set of electro-hydraulic actuators and racks 30 to drive multiple gears 31 to realize the operation of the system.
