[0030] 5. When the battery is pushed into a cavity in the processing chamber, it is sensed by the sensor and drives the electric push rod to retract. The closed door connected to the output end of the electric push rod will seal the cavity. At the same time, the capsule inside the cavity will explode and spray the fire extinguishing agent to extinguish the fire and reduce the temperature, thereby isolating the battery with sudden temperature change and performing adaptive cooling and fire extinguishing treatment.

DETAILED DESCRIPTION

[0045] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0046] See also Figures 1 to 13 , the present invention provides a technical solution: Figure 1 、 Figure 2 and Figure 3 As shown, it includes an explosion-proof mechanism 1 for cooling and extinguishing a portion of batteries that are overheated or burning;

[0047] The buffer mechanism 2 is used for performing multi-stage buffering on the battery, and the outer side of the buffer mechanism 2 is connected to the explosion-proof mechanism 1.

[0048] The explosion-proof mechanism 1 includes a processing chamber 11, wherein the interior of the processing chamber 11 is divided into a plurality of placement cavities, and the outer side of the processing chamber 11 is fixedly connected with an embedded rod 12, wherein the embedded rod 12 is used to connect the buffer mechanism 2 and the explosion-proof mechanism 1;

[0049] A sensor 13 is fixedly mounted on one side of the processing chamber 11 away from the splicing rod 12. The sensor 13 is protected by a heat-insulating and explosion-proof cover. A capsule 14 is fixedly mounted inside the processing chamber 11. The capsule 14 is used to cool down and extinguish hot or burning batteries.

[0050] Both ends of the processing chamber 11 are symmetrically connected to electric push rods 16, wherein the electric push rods 16 are controlled by the sensor 13. The output end of the electric push rods 16 is fixedly connected to the closed door 15, which is respectively inserted into the two ends of the processing chamber 11 and extends into the interior thereof. 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. The limiting door 37 connected to the other side of the tough pad 38 will deflect outward through the fixed axis, and eventually 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. 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 it down, thereby isolating the battery with sudden temperature change and performing adaptive cooling and fire extinguishing treatment.

[0051] like Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 and Figure 9 As shown, the buffer mechanism 2 includes a battery cell 21, the outer side of which is fitted with the embedded rod 12, a partition frame 22 fixedly mounted inside the battery cell 21, shock-absorbing rubber plates 23 fixedly mounted on both ends of the partition frame 22 and inside the battery cell 21, and a buffer capsule 24 fixedly connected to the side of the shock-absorbing rubber plate 23 away from the partition frame 22. Because the battery cell is used for ship energy storage, it is inevitably affected by vibration. Shock-absorbing rubber plates 23 are fixedly mounted on both sides of the battery cell 21, and a number of buffer capsules 24 are fixedly mounted on the outer sides of the shock-absorbing rubber plates 23. The buffer capsules 24 reduce external vibration and impact force and belong to the first level of buffer defense, while the shock-absorbing rubber plates 23 belong to the second level of buffer defense and can offset external impact force and vibration to a greater extent.

[0052] A buffer assembly 25 is provided inside the chamber 21 and on the partition frame 22. The buffer assembly 25 includes a piezoelectric sensor 31. The piezoelectric sensor 31 is fixedly mounted on the top of the chamber 21. The piezoelectric sensor 31 utilizes the positive piezoelectric effect to control the generation of charge.

[0053] The piezoelectric sensor 31 is connected to a small electric field generator 32 via wires. In addition, the piezoelectric sensor 31 senses and transmits different vibration forces, allowing the small electric field generator 32 to change the intensity of the applied electric field, which can accurately control the viscosity and stiffness of the electrorheological fluid, allowing it to adaptively adjust the buffering and protection effects according to different degrees of vibration or impact. For example, for smaller vibrations, a lower intensity electric field is applied to give the electrorheological fluid an appropriate viscosity to absorb vibration energy; for larger impacts, a high intensity electric field is applied to allow the electrorheological fluid to quickly become harder and provide stronger protection. This adaptive adjustment capability ensures that the battery can be optimally protected under various external forces. The outside of the small electric field generator 32 is connected to a circuit 33;

[0054] An emergency handle 34 is inserted on the outside of the bin body 21, which allows the operator to manually push the battery out. A square bin 305 is fixedly mounted inside the bin body 21 and on the partition frame 22. Fixed rails 39 are fixedly connected to the upper and lower sides of the inner cavity of the square bin 305. The inner sliding surface of the fixed rails 39 is adapted to slide onto the sliding platform 30.

[0055] The outer end face of the square bin 305 is fixedly connected to a support 36, and the interior of the support 36 is rotatably connected to a limit door 37 via a fixed axis, and a tough pad 38 is fixedly connected to the outer side of the limit door 37; then the limit door 37 is deflected downward by a fixed axis fixedly connected to the interior of the support 36 to achieve the sealing of the square bin 305, wherein the tough pad 38 fixedly connected to the outer side of the limit door 37 plays a role in compensating the distance between the limit door 37 and the placement frame 302, thereby preventing the battery from moving in the placement frame 302 due to vibration or impact, and at the same time, the tough pad 38 is tightly squeezed and adapted to the inner wall of the square bin 305, and the tough pad 38 has high thermal conductivity.

[0056] The surface of the fixed rail 39 is inserted with a limit rod 35, wherein the limit rod 35 is used to limit the sliding platform 30, and the limit rod 35 is respectively inserted into the surface of the square bin 305 and the bin body 21 and extends to the outside of the device; when the battery is placed, the limit rod 35 is passed through the bin body 21, the square bin 305 and the fixed rail 39 in turn, thereby playing a role in limiting the sliding platform 30.

[0057] A flexible ring 301 is provided on the top of the sliding table 30, wherein the interior of the flexible ring 301 is filled with electrorheological fluid, and the inner side of the flexible ring 301 is squeezed and adapted to be fitted with a placement frame 302, wherein the placement frame 302 is a place for storing batteries; when the device is hit, vibrated, or vibrates itself, the piezoelectric sensor 31 installed on the top of the compartment 21 will receive a signal, wherein the piezoelectric sensor 31 is integrated and is composed of a plurality of piezoelectric sensors 31, so as to avoid the small electric field generator 32 from being unable to operate normally due to insufficient charge, and the piezoelectric sensor 31 is a sensor based on the piezoelectric effect, and it is a positive piezoelectric effect, which means that when certain dielectrics are deformed by external forces, polarization will occur inside them, and at the same time, equal and opposite charges will appear on the 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, when a force is applied in a certain direction, causing it to deform, an electric charge is generated on a certain surface. When the external force is removed, the battery returns to its normal, uncharged state. The piezoelectric sensor 31 then generates these charges and flows into the small electric field generator 32. The small electric field generator 32 then generates an electric field in the circuit 33. The conductive polymer material used in the placement frame 302 has a strong ability to isolate the electric field. Under the influence of the electric field, the electrorheological fluid (ERF) hardens. The ERF is stored inside the flexible ferrule 301. Under the action of the electric field, the ERF can quickly change state from liquid to solid or have a higher viscosity. When the battery is vibrated or impacted, the corresponding sensor detects the signal and immediately applies an electric field, causing the ERF to quickly harden, providing support and cushioning for the battery in a very short time, effectively reducing the impact of vibration or impact on the battery. This rapid response characteristic can instantly activate the protection mechanism, and compared with some traditional mechanical buffer devices, it can respond to sudden external force impacts more promptly.

[0058] The spacer 303 is used to separate the placement frame 302 from the battery to avoid affecting the heat dissipation process. The spacer 303 is fixedly connected to the inner side of the placement frame 302. The square bin 305 is placed in the bin body 21 and placed on the partition frame 22. The upper and lower sides of the inner cavity of the square bin 305 are fixedly connected to the fixed rails 39. Therefore, the sliding platform 30 is moved inward along the fixed rails 39 toward the interior of the square bin 305. The sliding platform 30 is fixedly installed with a flexible ring 301, and the inner side of the flexible ring 301 is squeezed and adapted to fit the placement frame 302. The placement frame 302 is a place for storing batteries, and the outer side of the battery is tightly attached to the spacer 303. The spacer 303 prevents the battery from contacting the placement frame 302 and affecting heat dissipation.

[0059] like Figure 10 、 Figure 11 and Figure 12 As shown, an adjustment assembly 304 is provided inside the square bin 305, wherein the adjustment assembly 304 includes a first telescopic rod 41, an internal spring 42 is fixedly connected to the interior of the first telescopic rod 41, and the internal spring 42 is connected to the output end of the first telescopic rod 41;

[0060] A tension spring 43 is fixedly connected to the output end of the first telescopic rod 41. An end of the tension spring 43 away from the first telescopic rod 41 is fixedly connected to an inner slide rod 44. The inner slide rod 44 is slidably adapted to the inside of the output end of the first telescopic rod 41.

[0061] The interior of the square bin 305 is fixedly connected to a center plate 406, the exterior of the center plate 406 is fixedly connected to a slotted sleeve 45, the interior of the slotted sleeve 45 is slidably adapted to fit a round rod 46, the bottom of the round rod 46 is fixedly connected to 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;

[0062] The outer side of the shape memory alloy spring 47 is fixedly connected to an external connecting bar 48, the bottom of the external connecting bar 48 is fixedly connected to a sleeve square plate 49, the bottom of the sleeve square plate 49 is fixedly connected to the 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 to the external connecting bar 48, and the bottom of the external connecting bar 48 is fixedly connected to the sleeve square plate 49, and 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.

[0063] The top of the round rod 46 is fixedly connected with an inclined plate 401, and the inclined surface of the inclined plate 401 is squeezed and adapted to fit with a covering rod 402. The internal 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. 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 plate 401 to move upward until it is aligned with the outer wall of the square bin 305. 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, which was originally 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. 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.

[0064] A reset bar 404 is fixedly connected to the outside of the covering rod 402. The reset bar 404 is elastic and provides a restoring force to the covering rod 402. It also prevents the covering rod 402 from being squeezed by the inclined plate 401 and moving away from the first telescopic rod 41 due to inertia. The end of the reset bar 404 away from the covering rod 402 is fixedly connected to an extension plate 405, which is fixedly connected to the outside of the fulcrum rod 403.

[0065] When using the present invention: First, place the square bin 305 into the bin body 21 and place it on the partition frame 22. The upper and lower sides of the inner cavity of the square bin 305 are fixedly connected to fixed rails 39. Then, move the sliding platform 30 inward along the fixed rails 39 toward the interior of the square bin 305. A flexible ring 301 is fixedly mounted on the sliding platform 30, and a placement frame 302 is squeezed and adapted on the inner side of the flexible ring 301. The placement frame 302 is used to store batteries, and the outer side of the battery is tightly attached to the partition bar 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 limit the sliding platform 30. Then, the limit door 37 is deflected downward by the fixed axis fixedly connected to the inside of the support 36 to achieve the sealing of the square bin 305. The tough pad 38 fixedly connected to the outside of the limit door 37 is used to prevent the battery from moving in the placement frame 302 due to vibration or impact. At the same time, the tough pad 38 is tightly squeezed and adapted to the inner wall of the square bin 305. In addition, the tough pad 38 has high thermal conductivity.

[0066] Because the battery compartment is used for ship energy storage, it will inevitably be affected by vibration. Shock-absorbing rubber plates 23 are fixedly installed on both sides of the compartment body 21, and several buffer capsules 24 are fixedly installed on the outside of the shock-absorbing rubber plates 23. The buffer capsules 24 will 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, which can offset external impact force and vibration to a greater extent. When the device is hit, vibrated, or vibrates itself, the piezoelectric sensor 31 installed on the top of the compartment 21 will receive a signal. The piezoelectric sensor 31 is a sensor based on the piezoelectric effect, which will generate electric charges through vibration. These generated charges will then flow into the small electric field generator 32, and the small electric field generator 32 will then cause the circuit 33 to generate an electric field, and the electrorheological fluid under the influence of the electric field will harden. The electrorheological fluid is stored inside the tough ring 301. Under the action of the electric field, the electrorheological fluid can quickly change state from liquid to solid or have a higher viscosity.

[0067] 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 plate 401 to move upward until the covering rod 402 is squeezed, wherein the inclined portion of the inclined plate 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, which was originally 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 use 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 plate 401 will continue to squeeze the covering rod 402, and finally the covering rod 402 will continue to deflect significantly counterclockwise 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 seal the cavity, and at the same time, the capsule body 14 set inside the cavity will explode and sprinkle fire extinguishing agent to extinguish the fire and reduce the temperature.

[0068] The above 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 concepts without creative work fall within the scope of protection of the present invention.
