Specific embodiments

[0037] Next, in combination with the drawings and specific embodiments, the present invention will be further described. It should be noted that, on the premise of non-conflict, any combination can be formed among the following-described embodiments or technical features, and it should be known that the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of protection of the present invention.

[0038] Please refer to Figures 1 to 13 , the present invention provides a technical solution: as Figure 1 , Figure 2 and Figure 3 shown, it includes an explosion-proof mechanism 1 for cooling and extinguishing batteries with excessively high temperature or combustion; a buffer mechanism 2 for performing multi-stage buffering treatment on the battery, and the outside of the buffer mechanism 2 is connected to the explosion-proof mechanism 1.

[0039] The explosion-proof mechanism 1 includes a processing chamber 11, and several placement cavities are divided inside the processing chamber 11. An embedding rod 12 is fixedly connected to the outside of the processing chamber 11, and the embedding rod 12 is used for connecting and processing between the buffer mechanism 2 and the explosion-proof mechanism 1; On one side of the processing chamber 11 away from the splicing rod 12, a sensor 13 is fixedly installed. The sensor 13 is protected by a heat-insulating and explosion-proof cover. Inside the processing chamber 11, a capsule 14 is fixedly installed, and the capsule 14 is used for cooling and extinguishing fires of high-temperature or burning batteries; Electric push rods 16 are symmetrically connected to both ends of the processing chamber 11. The electric push rods 16 are controlled by the sensor 13. The output ends of the electric push rods 16 are fixedly connected to closing doors 15. The closing doors 15 respectively penetrate through both ends of the processing chamber 11 and extend into its interior. When the temperature of the battery is too high and there is a tendency to burn, the shape memory alloy spring 47 will be fully stretched. Immediately afterwards, the round rod 46 will quickly move upward along the slotted tube sleeve 45. Subsequently, the inclined panel 401 will continue to squeeze the covering rod 402. Finally, the covering rod 402 will continue to deflect counterclockwise significantly through the fulcrum rod 403. At this time, the first telescopic rod 41 will not be restricted and will extend outward under the action of the built-in spring 42. Then it will drive the inner sliding rod 44 to squeeze the battery outward again until the battery impacts the resilient pad 38. The limiting door 37 connected to the other side of the resilient pad 38 will deflect outward through the fixed shaft. Finally, the battery will be pushed into a cavity of the processing chamber 11. Immediately afterwards, it will be sensed by the sensor 13 and drive the electric push rod 16 to contract. The closing door 15 connected to the output end of the electric push rod 16 will seal the cavity. At the same time, the capsule 14 arranged inside the cavity will burst and sprinkle out the fire extinguishing agent for fire extinguishing and cooling treatment, thus playing a role in isolating the battery with sudden temperature change and performing adaptive cooling and fire extinguishing treatment on it.

[0040] As Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown in, the buffer mechanism 2 includes a housing 21. The outside of the housing 21 is fitted with the splicing rod 12 in an embedded manner. Inside the housing 21, a partition frame 22 is fixedly installed. Shock-absorbing rubber plates 23 are fixedly installed at both ends of the partition frame 22 and inside the housing 21. A buffer capsule 24 is fixedly connected to the side of the shock-absorbing rubber plate 23 away from the partition frame 22. Since this battery compartment is used for ship energy storage, the battery compartment will inevitably be affected by vibrations. Shock-absorbing rubber plates 23 are fixedly installed on both sides of the housing 21, and a number of buffer capsules 24 are fixedly installed on the outside of the shock-absorbing rubber plates 23. The buffer capsules 24 will reduce the external vibration and impact force and belong to the first-level buffer defense line, while the shock-absorbing rubber plates 23 belong to the second-level buffer defense line and can offset the external impact force and vibration to a greater extent.

[0041] Buffer components 25 are provided both inside the bin body 21 and on the partition rack 22. The buffer component 25 includes a piezoelectric sensor 31, which is fixedly installed on the top of the bin body 21. The piezoelectric sensor 31 utilizes the direct piezoelectric effect to control the generation of charge. The piezoelectric sensor 31 is connected to a small electric field generator 32 through a wire. Additionally, through the induction and transmission of different vibration forces by the piezoelectric sensor 31, the small electric field generator 32 can change the intensity of the applied electric field, precisely controlling the viscosity and stiffness of the electrorheological fluid, enabling it to adaptively adjust the buffering and protection effects according to different degrees of vibration or impact. For example, for minor vibrations, a lower-intensity electric field is applied, causing the electrorheological fluid to have an appropriate viscosity to absorb the vibration energy; while for a larger impact, a high-intensity electric field is applied, making the electrorheological fluid quickly turn into a harder state to provide stronger protection. This adaptive adjustment ability can ensure that the battery is provided with the best protection under various external forces. The outside of the small electric field generator 32 is connected to a circuit 33. An emergency handle 34 is inserted on the outside of the bin body 21, and the emergency handle 34 serves to manually push the battery outwards by the operator. Square bins 305 are fixedly installed both inside the bin body 21 and on the partition rack 22. Fixed rails 39 are fixedly connected to both the upper and lower sides of the inner cavity of the square bin 305, and a sliding table 30 is slidably fitted inside the fixed rails 39. A support 36 is fixedly connected to the outer end face of the square bin 305. A limiting door 37 is rotatably connected to the inside of the support 36 through a fixed shaft. A resilient pad 38 is fixedly connected to the outside of the limiting door 37. Then, the limiting door 37 is deflected downward through the fixed shaft fixedly connected inside the support 36 to achieve the blocking treatment of the square bin 305. The resilient pad 38 fixedly connected to the outside of the limiting door 37 serves to compensate for the distance between the limiting door 37 and the placement frame 302, preventing the battery from moving in the placement frame 302 due to vibration or impact. At the same time, the resilient pad 38 is tightly squeezed and adapted to the inner wall of the square bin 305. Additionally, the resilient pad 38 has high heat conductivity.

[0042] A limiting rod 35 is inserted on the surface of the fixed rail 39, and the limiting rod 35 is used for limiting the sliding table 30. The limiting rod 35 respectively penetrates the surfaces of the square bin 305 and the bin body 21 and extends to the outside of the device. After the battery is placed, the limiting rod 35 passes through the bin body 21, the square bin 305, and the fixed rail 39 in sequence, thereby playing a role in limiting the sliding table 30.

[0043] A resilient collar 301 is provided on the top of the sliding table 30. The interior of the resilient collar 301 is filled with electrorheological fluid. An inner side of the resilient collar 301 is press-fitted with a placement frame 302, where the placement frame 302 is a place for storing batteries. When the device is impacted, vibrated, or vibrates on its own, the piezoelectric sensor 31 installed on the top of the housing 21 will receive a signal. The piezoelectric sensor 31 is an integrated type and is composed of several piezoelectric sensors 31, so as to avoid the situation where too little charge cannot support the normal operation of the small electric field generator 32. And the piezoelectric sensor 31 is a sensor based on the piezoelectric effect, and it is the positive piezoelectric effect. The positive piezoelectric effect means that when some dielectrics are deformed under the action of an external force, polarization phenomena will occur inside them. At the same time, equal amounts of opposite charges will appear on two opposite surfaces of the dielectric, and the charge density is proportional to the magnitude of the external force. The external force here can be in various forms, including unidirectional force, reciprocating force, impact force, etc. That is to say, when a force is applied to it in a certain direction to cause deformation, charges will be generated on a certain surface. When the external force is removed, it will return to the normal non-charged state again. For the piezoelectric sensor 31, then these generated charges will flow into the small electric field generator 32. Then the small electric field generator 32 will generate an electric field in the circuit 33. The placement frame 302 is made of a conductive polymer material and has a strong ability to isolate the electric field. The electrorheological fluid under the influence of the electric field will harden. The electrorheological fluid is stored inside the resilient collar 301. The electrorheological fluid can quickly change its state under the action of an electric field, changing from a liquid state to a solid state or having a higher viscosity. When the battery is vibrated or impacted, after the corresponding sensor detects the signal, an electric field can be immediately applied to make the electrorheological fluid quickly harden, providing support and buffering for the battery in a very short time and effectively reducing the impact of vibration or impact on the battery. This fast response characteristic can activate the protection mechanism instantly and can respond to sudden external force impacts more timely than some traditional mechanical buffer devices.

[0044] The partition strip 303 is used to separate the placement frame 302 from the battery to avoid affecting the heat dissipation process. The partition strip 303 is fixedly connected to the inner side of the placement frame 302. The square bin 305 is placed into the housing 21 and placed on the partition shelf 22. Both the upper and lower sides of the inner cavity of the square bin 305 are fixedly connected with fixed rails 39. Therefore, the sliding table 30 is moved along the fixed rails 39 into the interior of the square bin 305. A resilient collar 301 is fixedly installed on the sliding table 30, and an inner side of the resilient collar 301 is press-fitted with a placement frame 302. The placement frame 302 is a place for storing batteries, and the outer side of the battery is closely attached to the partition strip 303. The partition strip 303 plays a role in preventing the battery from contacting the placement frame 302 and affecting heat dissipation.

[0045] Such as Figure 10 、Figure 11 and Figure 12 As shown, an adjustment component 304 is disposed inside the square bin 305, wherein the adjustment component 304 includes a first telescopic rod 41, an internal spring 42 is fixedly connected inside the first telescopic rod 41, and the internal spring 42 is connected to the output end of the first telescopic rod 41; A tension spring 43 is fixedly connected inside the output end of the first telescopic rod 41, and an inner slide bar 44 is fixedly connected to one end of the tension spring 43 away from the first telescopic rod 41. The inner slide bar 44 is slidably adapted inside the output end of the first telescopic rod 41; The interior of the square bin 305 is fixedly connected with a center plate 406, the outer side of the center plate 406 is fixedly connected with a slotted sleeve 45, the interior of the slotted sleeve 45 is slidably adapted with a round rod 46, the bottom of the round rod 46 is fixedly connected with a shape memory alloy spring 47, and the bottom end of the shape memory alloy spring 47 is fixedly connected to the center plate 406; The outer side of the shape memory alloy spring 47 is fixedly connected with an external connecting strip 48, the bottom of the external connecting strip 48 is fixedly connected with a sleeve square plate 49, the bottom of the sleeve square plate 49 is fixedly connected with a No. 2 telescopic rod 40, and the bottom end of the No. 2 telescopic rod 40 is fixedly connected to the center plate 406; wherein the outer side of the shape memory alloy spring 47 is fixedly connected with the external connecting strip 48, and the bottom of the external connecting strip 48 is fixedly connected with the sleeve square plate 49, the sleeve square plate 49 serves to connect the remaining three shape memory alloy springs 47, so that when one shape memory alloy spring 47 is stretched, the others will be stretched synchronously, and the No. 2 telescopic rod 40 fixedly connected to the bottom of the sleeve square plate 49 serves to support it.

[0046] The top of the round rod 46 is fixedly connected with an inclined panel 401, the inclined surface of the inclined panel 401 is pressed and adapted with a covering rod 402, the inner rotation of the covering rod 402 is connected with a fulcrum rod 403, and the bottom end of the fulcrum rod 403 is fixedly connected to the inner wall of the square bin 305; when the temperature of the battery is abnormal, the temperature inside the placement frame 302 will rise rapidly, and the shape memory alloy spring 47 will be slightly stretched due to the temperature increase, and then the round rod 46 fixedly connected to the top thereof will move slightly upward, and drive the inclined panel 401 to move upward until the battery is in the correct position. The covering rod 402 is squeezed, wherein the inclined portion of the inclined panel 401 is squeezed and adapted to the covering rod 402, so the covering rod 402 will be slightly deflected counterclockwise through the fulcrum rod 403, and the inner sliding rod 44 initially limited by the covering rod 402 will extend outward under the elastic force of the tension spring 43, but will not separate from the No. 1 telescopic rod 41, and the extended covering rod 402 will push the battery toward the direction of the tough pad 38 and contact it, thereby utilizing the high thermal conductivity of the tough pad 38 to cool the battery.

[0047] A reset strip 404 is fixedly connected to the outer side of the covering rod 402. The reset strip 404 fixedly connected to the outer side of the covering rod 402 is elastic and functions to give the covering rod 402 a reset force. At the same time, it also functions to prevent the covering rod 402 from being squeezed by the inclined panel 401 and moving away from the first telescopic rod 41 under the action of inertia. One end of the reset strip 404 away from the covering rod 402 is fixedly connected to an extension plate 405, and the extension plate 405 is fixedly connected to the outer side of the fulcrum rod 403.

[0048] When the present invention is in use: First, the square bin 305 is placed into the bin body 21 and placed on the partition frame 22. Fixed rails 39 are fixedly connected to both the upper and lower sides of the inner cavity of the square bin 305. Therefore, the sliding table 30 is moved inward along the fixed rails 39 into the interior of the square bin 305. A resilient collar 301 is fixedly installed on the sliding table 30, and a placement frame 302 is press-fitted to the inner side of the resilient collar 301. The placement frame 302 is a place for storing batteries, and the outer sides of the batteries are closely adhered to the partition strips 303. After the batteries are placed, the limiting rod 35 is sequentially passed through the bin body 21, the square bin 305, and the fixed rails 39 to perform a limiting process on the sliding table 30. Then, the limiting door 37 is deflected downward through the fixed shaft fixedly connected inside the support 36 to achieve the blocking process of the square bin 305. A resilient pad 38 fixedly connected to the outer side of the limiting door 37 is to prevent the batteries from moving in the placement frame 302 due to vibration or impact. At the same time, the resilient pad 38 is closely press-fitted to the inner wall of the square bin 305. In addition, the resilient pad 38 has high heat conductivity.

[0049] Since this battery bin is used for ship energy storage, the battery bin will inevitably be affected by vibration. Shock-absorbing rubber plates 23 are fixedly installed on both sides of the bin body 21, and a number of buffer bags 24 are fixedly installed on the outer sides of the shock-absorbing rubber plates 23. The buffer bags 24 reduce external vibration and impact force and belong to the first-level buffer defense line, while the shock-absorbing rubber plates 23 belong to the second-level buffer defense line and can offset external impact force and vibration to a greater extent. When the device is impacted, vibrated, or generates vibration itself, the piezoelectric sensor 31 installed on the top of the bin body 21 will receive a signal. And the piezoelectric sensor 31 is a sensor based on the piezoelectric effect and will generate charges through vibration. Then these generated charges will flow into the small electric field generator 32. Then the small electric field generator 32 will cause an electric field to be generated in the circuit 33, and the electrorheological fluid stored inside the resilient collar 301 will become hard under the influence of the electric field. The electrorheological fluid can quickly change its state under the action of the electric field, changing from a liquid state to a solid state or having a higher viscosity.

[0050] When the temperature of the battery becomes abnormal, the temperature inside the placement frame 302 will rise rapidly. At this time, the shape memory alloy spring 47 will be slightly stretched due to the temperature increase, and then the round rod 46 fixedly connected to its top will move slightly upward, and drive the inclined panel 401 to move upward until the covering rod 402 is squeezed, wherein the inclined portion of the inclined panel 401 is squeezed and adapted to the covering rod 402, so the covering rod 402 will be slightly deflected counterclockwise through the fulcrum rod 403. At this time, the inner sliding rod 44 initially limited by the covering rod 402 will extend outward under the elastic force of the tension spring 43, but will not separate from the No. 1 telescopic rod 41, and the extended covering rod 402 will push the battery toward the direction of the tough pad 38 and contact it, so as to utilize the high thermal conductivity of the tough pad 38 to cool the battery. When the temperature of the battery is too high and there is a tendency to burn, the shape memory alloy spring 47 will be fully stretched, and then the round rod 46 will quickly move upward along the slotted sleeve 45, and then the inclined panel 401 will continue to squeeze the covering rod 402, and finally the covering rod 402 will continue to deflect counterclockwise by a large margin through the fulcrum rod 403. At this time, the No. 1 telescopic rod 41 will not be restricted, and will extend outward under the action of the built-in spring 42, and then drive the inner slide rod 44 to squeeze the battery outward again until the battery hits the tough pad 38, and the limit door 37 connected to the other side of the tough pad 38 will deflect outward through the fixed axis, and finally the battery will be pushed into a cavity in the processing chamber 11, and then it will be sensed by the sensor 13 and drive the electric push rod 16 to contract, and the closing door 15 connected to the output end of the electric push rod 16 will close the cavity, and at the same time, the capsule body 14 arranged inside the cavity will explode and sprinkle the fire extinguishing agent to extinguish the fire and cool down.

[0051] The above-mentioned embodiments are only preferred embodiments of the present invention, and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above-mentioned concepts without creative work all fall within the scope of protection of the present invention.
