Description

Technical Field

[0001] This utility model belongs to the field of lithium battery technology, specifically a protective mechanism for marine lithium batteries. Background Technology

[0002] Lithium-ion batteries are batteries that use lithium metal or lithium-containing compounds as positive and negative electrode materials. They have advantages such as high energy density, lightweight, no memory effect, and low self-discharge rate, and are therefore widely used in energy storage. However, lithium-ion batteries may overheat and cause thermal runaway during operation, which can lead to fires or explosions. In a confined environment, heat transfer can create a "domino effect," spreading to other batteries and causing more violent fires and explosions. Therefore, lithium-ion batteries used in ships require a reliable protective structure.

[0003] The existing technology still has the following shortcomings:

[0004] 1. Existing protective mechanisms for marine lithium batteries lack the function of effectively clamping the lithium batteries during use. On ships, lithium batteries are constantly swaying, requiring not only effective clamping to prevent them from shaking, but also cushioning and shock absorption. Existing lithium battery protection structures are insufficient to meet current needs.

[0005] 2. Existing protective mechanisms for marine lithium batteries still suffer from a lack of effective heat dissipation during use. Lithium batteries generate heat during operation, and the accumulation of heat may lead to overheating and thermal runaway. Utility Model Content

[0006] To overcome the above-mentioned defects, this utility model provides a protective mechanism for marine lithium batteries, which solves the problems of lacking effective clamping, shock absorption and heat dissipation functions for lithium batteries.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective mechanism for a marine lithium battery, comprising a protective housing, a lithium battery support plate disposed inside the protective housing, a bidirectional lead screw rotatably connected inside the lithium battery support plate, two clamping plates threadedly connected to the outer side of the bidirectional lead screw, a knob rotatably connected to one end of the lithium battery support plate, the knob being fixedly connected to one end of the bidirectional lead screw, and a spring telescopic rod fixedly connected below the lithium battery support plate, the lower end of the spring telescopic rod being fixedly connected to the inner bottom of the protective housing.

[0008] As a further embodiment of this utility model, rubber pads are fixedly connected to the inner sides of both clamping plates.

[0009] As a further embodiment of this utility model: a protective cover is provided on the top of the protective box, an adjusting screw is threadedly connected to the middle of the protective cover, a knob is fixedly connected above the adjusting screw, and an adjusting plate is rotatably connected below the adjusting screw.

[0010] As a further embodiment of this utility model: a plurality of springs are fixedly connected to the lower part of the adjusting plate, and a lower pressure plate is fixedly connected to the lower part of the springs.

[0011] As a further embodiment of this utility model, a cooling fan is provided on one side of the protective enclosure.

[0012] As a further embodiment of this utility model, an air outlet is provided on the other side of the protective box.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. By setting two clamping plates driven by a knob and a two-way lead screw, the lithium battery can be effectively clamped, preventing it from falling off due to the rocking of the ship. At the same time, rubber pads are set on the two clamping plates to prevent damage to the lithium battery during clamping and to improve the anti-slip effect.

[0015] 2. By installing a spring telescopic rod under the lithium battery carrier plate and an adjustable adjustment plate and a pressure plate under the protective box cover, a buffer and shock absorption function is provided when the lithium battery is further fixed. A cooling fan and an air outlet are installed on the protective box to prevent the lithium battery from overheating. Attached Figure Description

[0021] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0022] like Figures 1-4 As shown, this utility model provides a technical solution:

[0023] A protective mechanism for a marine lithium battery includes a protective housing 1. Inside the protective housing 1 is a lithium battery support plate 2. A bidirectional lead screw 3 is rotatably connected inside the lithium battery support plate 2. Two clamping plates 4 are threaded onto the outer side of the bidirectional lead screw 3. A knob 5 is rotatably connected to one end of the lithium battery support plate 2 and is fixedly connected to one end of the bidirectional lead screw 3. A spring telescopic rod 6 is fixedly connected to the lower part of the lithium battery support plate 2, and its lower end is fixedly connected to the inner bottom of the protective housing 1. Rubber pads 7 are fixedly connected to the inner sides of both clamping plates 4. The operator places the lithium battery on top of the lithium battery support plate 2, positioning it between the two clamping plates 4. Then, by rotating the knob 5, the bidirectional lead screw 3 rotates, causing the two clamping plates 4 to move closer together, clamping the lithium battery. The rubber pads 7 prevent damage to the lithium battery during clamping and also improve the anti-slip effect. The spring telescopic rod 6 acts as a shock absorber for the lithium battery support plate 2.

[0024] A protective cover 8 is provided on the top of the protective box 1. An adjusting screw 9 is threadedly connected to the middle of the protective cover 8. A knob 13 is fixedly connected above the adjusting screw 9. An adjusting plate 10 is rotatably connected below the adjusting screw 9. Several springs 11 are fixedly connected below the adjusting plate 10. A lower pressure plate 12 is fixedly connected below the springs 11. When the operator rotates the knob 13, it drives the adjusting screw 9 to rotate. When the adjusting screw 9 rotates, it drives the adjusting plate 10 to move downward. The adjusting plate 10 drives the lower pressure plate 12 to move downward through the springs 11. The lower pressure plate 12 and the adjusting plate 10 further buffer and dampen the lithium battery.

[0025] A cooling fan 14 is provided on one side of the protective housing 1, and an air outlet 15 is provided on the other side of the protective housing 1. When the cooling fan 14 is turned on, the lithium battery inside the protective housing 1 is cooled, and the hot air is discharged from the air outlet 15.

[0026] The working principle of this utility model is as follows:

[0027] First, the operator places the lithium battery on top of the lithium battery carrier plate 2 and between the two clamping plates 4. Then, the operator turns knob 5 to rotate the bidirectional lead screw 3. At this time, the bidirectional lead screw 3 moves the two clamping plates 4 closer together, clamping the lithium battery. The rubber pad 7 can prevent damage to the lithium battery during clamping and also improve the anti-slip effect. The spring telescopic rod 6 plays a shock-absorbing and buffering role for the lithium battery carrier plate 2. Then, the operator turns knob 13 to rotate the adjusting lead screw 9. When the adjusting lead screw 9 rotates, it moves the adjusting plate 10 downward. The adjusting plate 10 drives the lower pressure plate 12 downward through the spring 11. The lower pressure plate 12 and the adjusting plate 10 further buffer and dampen the lithium battery. The cooling fan 14 is turned on to dissipate heat from the lithium battery inside the protective box 1. The hot air is discharged from the air outlet 15 to prevent the lithium battery from overheating.

[0028] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
