Description

Technical Field

[0001] The present invention relates to the technical field of shipborne batteries, and particularly to an explosion-proof and protective device for shipborne batteries. Background Art

[0002] Shipborne batteries are the core components of a ship's power system, providing stable power supply for the ship and ensuring the safety of the ship in case of emergencies. During the operation of the ship, as an important energy supply device, the safety of the battery is directly related to the life and property safety of the ship and the crew.

[0003] Prior Art One (a Chinese patent with publication number CN220420774U and publication date January 30, 2024) is a lead-acid battery for ships; it includes a base, a spring member, a mounting seat, a battery body, a marine inclinometer, and two adjusting mechanisms. Each adjusting mechanism includes a rotating ring, a rotating assembly, a threaded rod, and a holding head. When the marine inclinometer detects that the ship is tilting in a certain direction, the rotating assembly located at the lower position is activated. Through the transmission gear, the corresponding rotating ring is driven to rotate, so that the threaded rod screws into the rotating ring, and the base is forced by the holding head, causing the mounting seat to tilt on the base in the opposite direction of the ship's tilt until the pointer of the marine inclinometer on the mounting seat is in the horizontal position, indicating that the battery body on the mounting seat is horizontal, thus preventing the battery body from tilting with the ship and causing the liquid electrolyte in the battery to flow due to the action of gravity, affecting the normal operation of the battery.

[0004] There is also Prior Art Two (a Chinese patent with publication number CN212342747U and publication date January 12, 2021) which is a marine battery box for placing batteries; the marine battery box includes a box body for placing the battery and a cover body for covering the box body. An adjustable connecting buckle is provided on the side wall of the box body along the length direction. The battery is placed in the box body, and then the battery is fastened by connecting it with the connecting buckle using a strap; a battery box for carrying the battery, which fixes and protects the battery, improving the overall safety.

[0005] Although the prior art can protect the battery and thus improve the overall placement safety, it cannot perform anti-corrosion treatment on shipborne batteries. When the battery undergoes long-term sea navigation operations with the ship, affected by harsh environments such as humid salt spray and high and low temperatures, its electrical appliances are prone to corrosion. After corrosion, chemical reactions will occur inside the battery, generating a large amount of gas, resulting in battery expansion or even explosion, posing a safety hazard.

[0006] Therefore, we propose an explosion-proof and protective device for shipborne batteries to solve the problems raised above. Summary of the Invention

[0007] The purpose of the present invention is to provide a shipboard battery explosion-proof protection device to solve the problem that the shipboard batteries in the current market cannot be treated for corrosion as proposed in the above-mentioned background technology. When the ship is sailing for a long time at sea, the battery is affected by harsh environments such as humid salt spray and high and low temperatures, and its electrical appliances are prone to corrosion. Chemical reactions will occur inside the corroded battery, thereby generating a large amount of gas, causing the battery to swell or even explode, posing a safety hazard.

[0008] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a shipborne battery explosion-proof protection device, comprising a battery assembly and a protection box for placing the battery assembly, the upper side of the protection box is docked with a protective cover, the battery assembly is placed inside the protection box, the interior of the protection box is fixedly connected with an anti-corrosion partition to prevent the battery assembly from corrosion, and an adjustable heat dissipation mechanism is provided between the side of the anti-corrosion partition and the inner wall of the protection box, the memory alloy arranged inside the heat dissipation mechanism can be adjusted to assist the battery assembly in heat dissipation treatment, and the adjusting heat dissipation mechanism can also perform explosion-proof treatment on the battery assembly.

[0009] Preferably, both left and right sides of the protective box are provided with mounting grooves, and the inner side of the mounting groove is fixedly connected with a mounting box, and the interior of the mounting box is fixedly connected with heat dissipation fins for preliminary heat dissipation of the battery assembly.

[0010] Preferably, two groups of anti-corrosion partitions are symmetrically arranged about the center point of the battery assembly, and the anti-corrosion partitions are tightly fitted to the sides of the battery assembly, and the outer side of the anti-corrosion partitions is coated with a polyaniline anti-corrosion sealant layer, and heat dissipation grooves are opened at equal intervals on the anti-corrosion partitions.

[0011] Preferably, the regulating heat dissipation mechanism includes a memory alloy, which is fixedly connected to the lower part of the side of the anti-corrosion partition, a fixing plate is fixedly connected between the side of the anti-corrosion partition and the inner wall of the protective box, and a moving rod is nested and connected to the inner side of the fixing plate, a sliding groove is opened on the side of the anti-corrosion partition, and a sliding block is nested and connected to the inside of the sliding groove, and a connecting plate is fixedly connected to the outer side of the sliding block, and two groups of connecting plates are symmetrically arranged about the center point of the anti-corrosion partition, and a sealing plate is fixedly connected between the two groups of anti-corrosion partitions.

[0012] Preferably, one side end of the moving rod is conically set, and the non-conical end of the moving rod is fixedly connected to a push plate, and the push plate is set in a "U"-shaped structure, and the other end of the push plate is fixedly connected to the center of the lower surface of the lower connecting plate, and a start button is fixedly connected to the lower side of the inner wall of the protective box, and the start button and the push plate are located in the same straight line position, and a start motor is fixedly connected to the side of the inner wall of the protective box, and the output end of the start motor is fixedly connected to a cooling fan, and the start motor and the start button are electrically connected.

[0013] Preferably, the width of the sealing plate is greater than the maximum value of the width of the heat dissipation groove, and the inner side of the sealing plate is closely attached to the outer side of the anti-corrosion partition plate. The connecting plate drives the slider through the push plate to form a sliding structure with the sliding groove.

[0014] Preferably, a fixed box is fixedly connected to the inner side of the protection box, and an airbag is placed inside the fixed box, and the airbag is filled with inert gas. A resisting plate is fixedly connected to the outer side of the moving rod, and a fixed spring is fixedly connected between the resisting plate and the fixed plate.

[0015] Preferably, the airbag is located on one side of the tapered portion of the moving rod. The resisting plate forms an elastic structure with the fixed plate through the fixed spring, and the push plate forms a sliding structure through the moving rod.

[0016] Preferably, the shape memory alloy is arranged in an "L" shape at normal temperature. The resisting plate is located on the side of the shape memory alloy at normal temperature, and when the shape memory alloy deforms, its edge end abuts against the resisting plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are: (1) The battery assembly can be preliminarily protected by the protection box and the protection cover, thereby reducing the possibility of damage to the battery assembly due to the shaking of the ship during navigation. At the same time, an anti-corrosion partition plate is arranged inside the protection box to further isolate the side of the battery assembly. The polyaniline anti-corrosion sealing glue layer coated on the outside of the anti-corrosion partition plate can isolate and anti-corrode the battery assembly, thereby reducing the phenomenon of corrosion of the battery assembly due to harsh environments such as humid salt spray during navigation operations, and further protecting the battery assembly.

[0018] (2) When the battery assembly operates for a long time, it will generate a certain amount of heat, and the heat accumulates inside the protection box. At this time, the heat dissipation fins arranged on the side of the protection box can discharge the accumulated heat inside to the outside, thereby reducing the excessive accumulation of heat inside the protection box and preventing the battery assembly from exploding due to too high a temperature.

[0019] (3) When the temperature inside the protective box continues to rise, the memory alloy will deform under the influence of the gradually rising temperature. At this time, the folding angle of the memory alloy gradually changes from a right angle to an obtuse angle. At the same time, the memory alloy will resist the contact plate on one side when opening, so that the contact plate drives the moving rod to move toward the side of the fixed plate. At this time, the contact plate will further squeeze the fixed spring. At the same time, the non-tapered end of the fixed plate will drive the push plate to move. The moving push plate will resist the pressing start button. After the start button is pressed, it will drive the start motor to run, so that the cooling fan will rotate. The rotating cooling fan will deliver wind. While blowing and cooling the battery assembly, the wind can also accelerate the heat-carrying gas to be discharged outward through the cooling fins, thereby further improving the heat dissipation efficiency of the battery assembly and reducing the possibility of explosion of the battery assembly.

[0020] (4) When the temperature inside the protective box is high, the memory alloy becomes a flat angle due to the high temperature. At this time, the end side of the memory alloy does not contact the contact plate. Driven by the elastic force of the fixed spring, the contact plate will drive the moving rod to move toward the airbag with a greater force. At this time, the tapered end of the moving rod will puncture the airbag, so that the inert gas filled in the airbag can diffuse into the protective box, thereby reducing the possibility of spontaneous combustion or even explosion of the battery assembly due to excessive temperature.

[0021] (5) When the push plate moves, it will synchronously drive the connecting plate to move. At this time, the connecting plate can drive the slider to move along the inside of the slide groove, so that the connecting plate can further drive the sealing plate to move stably along one side of the anti-corrosion partition. At this time, the sealing plate does not block the heat dissipation groove opened on the anti-corrosion partition, so that the battery assembly can better dissipate heat.

[0026] The battery assembly 1 can be initially protected by the protective box 2 and the protective cover 3, thereby reducing the possibility of damage to the battery assembly 1 due to the shaking of the ship during navigation. At the same time, an anti-corrosion partition 6 is arranged inside the protective box 2 to further isolate the side of the battery assembly 1. The polyaniline anti-corrosion sealant layer coated on the outside of the anti-corrosion partition 6 can isolate and anti-corrode the battery assembly 1, thereby reducing the corrosion of the battery assembly 1 due to harsh environments such as humid salt spray during navigation operations, and further protecting the battery assembly 1.

[0027] Embodiment 2: As Figure 1 , Figure 3 , Figure 4 , Figure 7 , Figure 8 , Figure 9 and Figure 10 shown in the technical solution, the present invention provides the following technical solution: a shipborne battery explosion-proof protection device, which discloses an adjustable heat dissipation mechanism. By means of the adjustable heat dissipation mechanism, the heat dissipation efficiency of the battery assembly 1 can be improved, and the possibility of explosion of the battery assembly 1 can be reduced: an anti-corrosion partition 6 that can prevent the battery assembly 1 from being corroded is fixedly connected inside the protective box 2, and an adjustable heat dissipation mechanism is arranged between the side of the anti-corrosion partition 6 and the inner wall of the protective box 2. The shape memory alloy 7 arranged inside the adjustable heat dissipation mechanism can assist the battery assembly 1 in heat dissipation. The adjustable heat dissipation mechanism includes a shape memory alloy 7, and the shape memory alloy 7 is fixedly connected to the lower part of the side of the anti-corrosion partition 6. A fixing plate 8 is fixedly connected between the side of the anti-corrosion partition 6 and the inner wall of the protective box 2, and a moving rod 19 is nested inside the inner side of the fixing plate 8. A sliding groove 17 is opened on the side of the anti-corrosion partition 6, and a slider 16 is nested inside the sliding groove 17. A connecting plate 14 is fixedly connected to the outside of the slider 16. Two groups of connecting plates 14 are symmetrically arranged up and down about the center point of the anti-corrosion partition 6, and a sealing plate 15 is fixedly connected between the two groups of anti-corrosion partitions 6. One end of the moving rod 19 is tapered, and a push plate 18 is fixedly connected to the non-tapered end of the moving rod 19. The push plate 18 is arranged in a "U" shape, and the other end of the push plate 18 is fixedly connected to the center of the lower surface of the lower connecting plate 14.

[0028] When the battery assembly 1 is running for a long time, a certain amount of heat will be generated, and the heat will be accumulated inside the protection box 2. At this time, the heat dissipation fins 4 arranged on the side of the protection box 2 can discharge the accumulated heat inside to the outside, thereby reducing the excessive heat accumulation inside the protection box 2, which makes the battery assembly 1 overheat and explode. When the temperature inside the protection box 2 continues to rise, the memory alloy 7 will deform under the influence of the gradually rising temperature. At this time, the folding angle of the memory alloy 7 gradually changes from a right angle to an obtuse angle. At the same time, the memory alloy 7 will resist the contact plate 20 on one side when opening, so that the contact plate 20 drives the moving rod 19 to the solid state. One side of the fixed plate 8 moves, and at this time the resistance plate 20 will further squeeze the fixed spring 21. At the same time, the non-tapered end of the fixed plate 8 will drive the push plate 18 to move. The moving push plate 18 will resist the pressing start button 12. After the start button 12 is pressed, it will drive the start motor 23 to run, so that the cooling fan 13 will rotate. The rotating cooling fan 13 will deliver wind force. The wind force can not only blow air to cool the battery assembly 1, but also accelerate the gas carrying heat to be discharged outward through the cooling fins 4, thereby further improving the heat dissipation efficiency of the battery assembly 1 and reducing the possibility of explosion of the battery assembly 1.

[0029] During the movement, the push plate 18 will synchronously drive the connecting plate 14 to move.

[0031] When the temperature inside the protective box 2 is high, the memory alloy 7 becomes a flat angle due to the high temperature. At this time, the end side of the memory alloy 7 does not contact the contact plate 20. Driven by the elastic force of the fixed spring 21, the contact plate 20 will drive the moving rod 19 to move toward the side of the airbag 10 with a greater force. At this time, the tapered end of the moving rod 19 will puncture the airbag 10, so that the inert gas filled in the airbag 10 can diffuse into the protective box 2, thereby reducing the possibility of spontaneous combustion or even explosion of the battery assembly 1 due to excessive temperature.
