Description

Technical Field

[0001] This invention belongs to the field of marine energy storage technology, and more specifically, relates to a battery rack with a buffer function for marine energy storage. Background Technology

[0002] A marine battery rack is a structural component specifically designed to support and mount battery packs, primarily used in electric and hybrid-powered vessels. With the increasing demand for environmentally friendly transportation, electric vessels are becoming increasingly important, and battery racks play a crucial supporting and protective role.

[0003] Chinese utility model patent publication number CN217589226U (application number CN202123042121.7) discloses a battery rack and a ship. The battery rack includes a frame, a connector, a positioning member, and a guide member. The frame has a receiving cavity, which extends through the outside of the frame along a first direction and forms an opening; the connector is placed at the opening and can be connected to the battery; the positioning member is placed inside the receiving cavity and can position the battery; the guide member is placed inside the receiving cavity, and the battery can move along the guide member when it enters or leaves the receiving cavity from the opening.

[0004] The aforementioned battery rack and vessel cannot solve the problem that excessive impact during the hoisting process may damage the batteries, resulting in short battery life, multiple subsequent maintenance, and high costs. Summary of the Invention

[0005] In view of this, the present invention provides a battery rack with a buffer function for marine energy storage, which can solve the problem of excessive impact on the battery during the hoisting process and improve the service life of the battery.

[0006] This invention is implemented as follows:

[0007] The present invention provides a battery rack with a buffer function for marine energy storage, including a battery rack, a plurality of battery racks located inside an energy storage cabinet, wherein the battery rack is a cuboid frame with multiple receiving cavities inside, and a plurality of elastic buffer devices are provided at the top and bottom of the battery rack, the elastic buffer devices being fixedly connected to the battery rack and the energy storage cabinet.

[0008] The technical advantages of the battery rack with buffer function for marine energy storage provided by this invention are as follows: The elastic buffer device can effectively absorb and reduce external impacts and vibrations from ship movement, wind, waves, and water surface turbulence. This helps protect the batteries in the battery rack from unnecessary stress and damage; ships may experience various mechanical impacts during navigation, such as hull vibration and turbulence, and the elastic buffer device can act as a buffer layer to reduce the transmission of these mechanical impacts to the batteries in the battery rack; by setting elastic buffer devices at the top and bottom of the battery rack, the position of the batteries in the battery rack can be stabilized, preventing them from sliding or shifting during ship movement, thereby improving the stability of the entire battery system; reducing the impact of vibration and impact on the batteries can extend battery life, reduce maintenance costs and the frequency of battery replacement; the elastic buffer device helps prevent batteries from being damaged under ship movement or severe weather conditions, improving ship safety; reducing the impact of external vibration can improve the performance stability of the batteries, ensuring reliable operation under different sea conditions; the elastic buffer device can also help reduce vibration noise generated by the battery system, improving comfort.

[0009] Based on the above technical solution, the battery rack with buffer function for ship energy storage of the present invention can be further improved as follows:

[0010] The elastic buffer device includes a connecting plate, a limiting plate, and a buffer pad. The connecting plate has an inverted U-shaped cross-section. The middle of the connecting plate is fixedly connected to the battery rack, and both ends of the connecting plate are fixedly connected to the energy storage cabinet. A buffer pad is provided at the bottom middle of the battery rack, and both ends of the buffer pad are fixedly connected to the limiting plate. The elastic buffer device is fixedly connected to the energy storage cabinet.

[0011] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the buffer pad at the bottom of the battery rack is responsible for bearing the total weight of the battery rack, and the connecting plates at the bottom and top of the battery rack are responsible for fixing the horizontal position of the battery rack.

[0012] The buffer pad located at the top of the battery rack is used to limit the vertical upward displacement of the battery rack when the energy storage cabinet shakes violently, so as to avoid collisions and damage caused by excessive displacement of the battery rack. Since the buffer device at the top of the battery rack is not used to support the weight of the battery rack, the number of elastic buffer devices at the top can be appropriately reduced.

[0013] Furthermore, a pad is provided at the bottom center of the connecting plate and at the top of the buffer pad. The thickness of the pad is less than the thickness of the buffer pad, and the pad is fixedly connected to the bottom center of the connecting plate.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a pad, the connecting plate and the buffer pad are in full contact, avoiding gaps between the connecting plate and the buffer pad, which would prevent the elasticity of the buffer pad from extending to the connecting plate. This allows the elasticity of the buffer pad to extend to the connecting plate, increasing the elasticity of the connecting plate and enabling it to withstand greater impact forces, thus ensuring the safety of the batteries in the battery rack.

[0015] Furthermore, the elastic buffer device is located at the four corners of the top and bottom receiving cavities of the battery holder.

[0016] By installing elastic buffer devices at the four corners of the top and bottom housing cavities of the battery rack, impacts and vibrations can be more evenly distributed onto the buffer pads, reducing localized stress concentrations on the battery rack and energy storage cabinet and helping to protect their integrity. The elastic buffer devices around the perimeter provide omnidirectional protection, effectively reducing the transmission of impacts or vibrations to the buffered areas regardless of their direction of origin. These peripheral elastic buffer devices increase the stability of the battery rack and energy storage cabinet, preventing tilting, swaying, or movement, especially on uneven surfaces. Distributing the elastic buffer devices around the housing cavities reduces the risk of damage to the structure or equipment from external impacts or vibrations, extending the battery rack's lifespan. Evenly distributed elastic buffer devices contribute to improved battery rack safety, reducing accidents and damage. The peripheral elastic buffer devices more comprehensively absorb and reduce vibrations and impacts, improving the battery rack's shock absorption performance.

[0017] Furthermore, the elastic buffer devices on the top and bottom left and right sides of the battery rack are installed vertically, while the elastic buffer device in the middle is installed horizontally.

[0018] All the elastic buffer devices have a uniform structure, only the installation direction is different. The elastic buffer device is rigid in one horizontal direction and elastic in the other directions. Multiple elastic buffer devices are connected to the battery rack and energy storage cabinet in different directions, so that the installation and fixation of the battery rack is both flexible and stable.

[0019] Furthermore, the cushioning pad is made of rubber.

[0020] Rubber possesses excellent shock absorption properties, effectively absorbing and reducing the effects of external impacts and vibrations, thereby protecting supported structures or equipment. As an elastic material, rubber can return to its original shape after being subjected to force, enabling it to provide reliable cushioning and support while preventing damage to equipment or structures. Rubber typically has a long service life and can withstand various environmental factors, making it a reliable cushioning material. Rubber generally has good grip, preventing equipment or structures from sliding or moving during vibration or motion, thus improving safety. Some types of rubber have good electrical insulation properties, making them suitable for use in electrical equipment and electronic applications to reduce the adverse effects of vibration on electronic components. Rubber materials can be customized to meet specific application requirements, including selecting different hardness, thickness, and shapes to satisfy specific cushioning needs.

[0021] Furthermore, the elastic buffer device includes a first buffer plate, a second buffer plate, and a spring. A cylindrical recess is provided at the junction of the energy storage cabinet and the battery rack. The bottom of the recess is fixedly connected to one end of the first buffer plate. The first buffer plate is a cylindrical block. The other end of the first buffer plate is fixedly connected to the bottom of the spring. The top of the spring is fixedly connected to one end of the second buffer plate. The other end of the second buffer plate is fixedly connected to the battery rack.

[0022] Springs effectively absorb shocks and vibrations, protecting battery racks and energy storage cabinets from damage. They store energy and release it to smoothly control or adjust the movement of the battery rack. By selecting appropriate materials and spring designs, the stiffness and elasticity of the springs can be adjusted and controlled to meet the needs of different applications. Springs mitigate sudden impacts and vibrations, reducing wear and fatigue on battery racks and energy storage cabinets, thus extending their lifespan. Springs provide controllable, smooth movement, ensuring the stability of the battery rack. Compared to other cushioning devices, springs are typically more compact, providing good cushioning even in limited spaces. Springs generally have a long lifespan and do not require frequent replacement or maintenance, helping to reduce equipment maintenance costs. Springs can adaptively provide different cushioning effects according to changes in load without additional adjustments or control.

[0023] Furthermore, the battery rack has a hollow cylinder around the spring, which is fixedly connected to the battery rack. The radius of the hollow cylinder is smaller than the radius of the recess on the energy storage cabinet and larger than the radius of the spring.

[0024] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a hollow cylinder outside the spring, it can be ensured that the battery rack moves along the direction of the hollow cylinder and that the spring extends and contracts in the vertical direction, thereby reducing the vibration of the battery rack.

[0025] Furthermore, the internal accommodating cavity of the battery rack is arranged in two rows, front and back, with the accommodating cavity inclined. The adjacent battery racks of the two rows of accommodating cavities are positioned lower, while the accommodating cavities further away from the battery racks are positioned higher. Each accommodating cavity has a supporting plate at its bottom, which is a rectangular iron sheet and is fixedly connected to the battery rack.

[0026] The beneficial effects of adopting the above-mentioned improved scheme are as follows: By positioning the adjacent ends of the front and rear rows of receiving cavities lower and the ends farther apart higher, the battery can be easily placed at the lower end and securely fixed to the battery rack, reducing the possibility of the battery moving during vibration or movement; battery installation is simpler, eliminating the need for additional support structures or devices to hold the battery within the receiving cavities of the battery rack, saving time and labor; it also effectively prevents the battery from accidentally moving out under inappropriate conditions, such as in transportation applications like ships or vehicles, or when the equipment is subjected to vibration or impact; preventing accidental battery movement helps improve the safety of the battery rack and avoids potential damage and safety risks; this design can make more efficient use of available space because the battery can be placed at the lower inner end without the need for additional gaps or supports; and simplified battery installation makes maintenance and replacement easier, thereby reducing maintenance costs.

[0027] Furthermore, a limiting piece is provided at the bottom of the outer side of the receiving cavity, and the limiting piece is fixedly connected to the battery holder. The limiting piece is a long strip of iron sheet from left to right.

[0028] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: by setting a limiting piece at the bottom of the outer side of the receiving cavity, the battery inside the receiving cavity is prevented from moving out when the battery rack moves significantly, thus avoiding damage to the battery.

[0029] Compared with existing technologies, the beneficial effects of the battery rack with buffer function for marine energy storage provided by this invention are:

[0030] Reducing Lifting Vibration: Battery racks on ships typically require lifting and installation during construction, repair, or refurbishment. Vibrations during lifting can damage battery racks and energy storage racks, and installing resilient cushioning devices can significantly reduce these vibrations. This helps ensure the stability of battery racks and energy storage units during installation, reducing the potential risk of equipment damage.

[0031] Enhancing Safety: Reducing vibration during lifting also helps improve safety at the work site. Lowering vibration levels can reduce the risk of injury to workers and operators during lifting operations. This is particularly important for the construction and maintenance of large ships and heavy equipment.

[0032] Extending Equipment Lifespan: The application of resilient cushioning devices helps extend the lifespan of battery racks and energy storage cabinets. Reducing vibration and impact during hoisting and transportation helps reduce wear and fatigue on the equipment. This means the battery racks will last longer and require less frequent replacement or repair, thus reducing maintenance costs.

[0033] Improving Equipment Performance: The resilient buffers on the outside of the battery rack also contribute to improved battery system performance. Vibration and shock can negatively impact normal battery operation, and by reducing these disturbances, batteries can operate more stably and reliably. This is particularly critical for shipboard electrical systems, which require a consistently reliable power supply.

[0034] Cost Reduction: Resilient buffers are less expensive to manufacture, and their application to battery racks can save costs in several ways. First, it reduces the cost of repairing and replacing the battery racks because the equipment's lifespan is extended. Second, it reduces the risk of damage during hoisting, thereby reducing potential repair and insurance costs. Finally, resilient buffers can also improve efficiency in manufacturing and installation, thus reducing labor costs.

[0035] Environmental benefits: Reducing damage to battery racks and energy storage cabinets and replacing them earlier helps reduce waste generation, aligning with the principles of sustainable development. At the same time, reducing equipment energy consumption and maintenance requirements also reduces waste of energy and resources. Attached Figure Description

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0045] Example 1

[0046] like Figure 1 , Figure 2 , Figure 3 , Figure 4 The image shows a first embodiment of a battery rack with a buffer function for ship energy storage provided by the present invention. In this embodiment, a battery rack 1 is included, and multiple battery racks 1 are located inside an energy storage cabinet 2. The battery rack 1 is a cuboid frame with multiple receiving cavities 11 inside. Multiple elastic buffer devices 3 are provided at the top and bottom of the battery rack 1, and the elastic buffer devices 3 are fixedly connected to the battery rack 1 and the energy storage cabinet 2.

[0047] In the above technical solution, the elastic buffer device 3 includes a connecting plate 31, a limiting plate 32, and a buffer pad 33. The connecting plate 31 has an inverted U-shaped cross section. The middle of the connecting plate 31 is fixedly connected to the battery rack 1, and both ends of the connecting plate 31 are fixedly connected to the energy storage cabinet 2. The bottom middle of the battery rack 1 is provided with a buffer pad 33, and both ends of the buffer pad 33 are fixedly connected to the limiting plate 32. The elastic buffer device 3 is fixedly connected to the energy storage cabinet 2.

[0048] Furthermore, in the above technical solution, a pad 34 is provided at the bottom center of the connecting plate 31 and at the top of the buffer pad 33. The thickness of the pad 34 is less than the thickness of the buffer pad 33, and the pad 34 is fixedly connected to the bottom center of the connecting plate 31.

[0049] Furthermore, in the above technical solution, the elastic buffer device 3 is located at the four corners of the top and bottom receiving cavity 11 of the battery holder 1.

[0050] Furthermore, in the above technical solution, the elastic buffer devices 3 on the top and bottom left and right sides of the battery rack 1 are installed longitudinally, while the elastic buffer device 3 in the middle is installed laterally.

[0051] Furthermore, in the above technical solution, the material of the buffer pad 33 is rubber.

[0052] Furthermore, in the above technical solution, the accommodating cavity 11 inside the battery rack 1 is arranged in two rows, front and back, with the accommodating cavity 11 tilted. The adjacent battery rack 1 is lower in the two rows of accommodating cavities 11, and the accommodating cavity 11 further away from the battery rack 1 is higher. Each accommodating cavity 11 has a supporting plate at the bottom from front to back. The supporting plate is a rectangular iron sheet and is fixedly connected to the battery rack 1.

[0053] Furthermore, in the above technical solution, a limiting piece is provided at the bottom of the outer side of the receiving cavity 11. The limiting piece is fixedly connected to the battery holder 1. The limiting piece is a long strip of iron sheet from left to right.

[0054] During installation, the battery is placed into the receiving cavity 11 along the receiving plate at the bottom of the receiving cavity 11. The limiting piece at the edge of the receiving cavity 11 prevents the battery from sliding out. When the energy storage cabinet 2 is hoisted or subjected to vibration, the battery rack 1 inside the energy storage cabinet 2 vibrates violently. The battery rack 1 moves downward and presses the connecting plate 31. The central part of the connecting plate 31 is subjected to pressure and undergoes a downward deformation. The pad 34 at the bottom of the connecting plate 31 transmits the deformation to the buffer pad 33. The buffer pad 33 is deformed by the pressure of the connecting plate 31 and then slowly rebounds, pushing the central part of the connecting plate 31 upward and driving the battery rack 1 back to its original position. At the same time, it reduces the vibration of the battery rack 1. The elastic buffer device 3 installed horizontally and vertically allows the elastic buffer device 3 to remain stationary in the horizontal direction while reducing the vibration of the battery rack 1 in the vertical direction.

[0055] Example 2

[0056] like Figure 1 , Figure 5 The image shows a second embodiment of a battery rack with a buffer function for ship energy storage provided by the present invention. In this embodiment, a battery rack 1 is included, and multiple battery racks 1 are located inside an energy storage cabinet 2. The battery rack 1 is a cuboid frame with multiple receiving cavities 11 inside. Multiple elastic buffer devices 3 are provided at the top and bottom of the battery rack 1, and the elastic buffer devices 3 are fixedly connected to the battery rack 1 and the energy storage cabinet 2.

[0057] In the above technical solution, the elastic buffer device 3 includes a first buffer plate 351, a second buffer plate 352, and a spring 36. A cylindrical recess is provided at the junction of the energy storage cabinet 2 and the battery rack 1. The bottom of the recess is fixedly connected to one end of the first buffer plate 351. The first buffer plate 351 is a cylindrical block. The other end of the first buffer plate 351 is fixedly connected to the bottom of the spring 36. The top of the spring 36 is fixedly connected to one end of the second buffer plate 352. The other end of the second buffer plate 352 is fixedly connected to the battery rack 1.

[0058] like Figure 1The image shows a second embodiment of a battery rack with a buffer function for ship energy storage provided by the present invention. In this embodiment, a hollow cylinder is provided around the spring 36 on the battery rack 1. The hollow cylinder is fixedly connected to the battery rack 1. The radius of the hollow cylinder is smaller than the radius of the recess on the energy storage cabinet 2 and larger than the radius of the spring 36.

[0059] Furthermore, in the above technical solution, the accommodating cavity 11 inside the battery rack 1 is arranged in two rows, front and back, with the accommodating cavity 11 tilted. The adjacent battery rack 1 is lower in the two rows of accommodating cavities 11, and the accommodating cavity 11 further away from the battery rack 1 is higher. Each accommodating cavity 11 has a supporting plate at the bottom from front to back. The supporting plate is a rectangular iron sheet and is fixedly connected to the battery rack 1.

[0060] Furthermore, in the above technical solution, a limiting piece is provided at the bottom of the outer side of the receiving cavity 11. The limiting piece is fixedly connected to the battery holder 1. The limiting piece is a long strip of iron sheet from left to right.

[0061] During installation, the battery is placed into the receiving cavity 11 along the receiving plate at the bottom of the receiving cavity 11. The limiting piece at the edge of the receiving cavity 11 prevents the battery from sliding out. When the energy storage cabinet 2 is hoisted or subjected to vibration, the battery rack 1 inside the energy storage cabinet 2 vibrates violently and moves downward, compressing the spring 36. When the pressure on the spring 36 is equal to the elastic force of the spring 36, the spring 36 extends, pushing the battery rack 1 upward and bringing the battery rack 1 back to its original position, reducing the vibration of the battery rack 1. The hollow cylinders on both sides of the spring 36 restrict the movement of the battery rack 1 in other directions, so that the battery rack 1 can only vibrate in the vertical direction.

[0062] Specifically, the principle of this invention is as follows: During installation, the battery is placed into the receiving cavity 11 along the receiving plate at the bottom of the receiving cavity 11. The limiting piece at the edge of the receiving cavity 11 prevents the battery from sliding out. When the energy storage cabinet 2 is hoisted or subjected to vibration, the battery rack 1 inside the energy storage cabinet 2 vibrates violently. The battery rack 1 moves downward and presses the connecting plate 31. The central part of the connecting plate 31 is subjected to pressure and undergoes a downward deformation. The pad 34 at the bottom of the connecting plate 31 transmits the deformation to the buffer pad 33. The buffer pad 33 is deformed by the pressure of the connecting plate 31 and then slowly rebounds, pushing the central part of the connecting plate 31 upward and driving the battery rack 1 back to its original position. At the same time, the vibration of the battery rack 1 is reduced. The elastic buffer device 3 installed horizontally and vertically allows the elastic buffer device 3 to remain stationary in the horizontal direction while reducing the vibration of the battery rack 1 in the vertical direction.
