Emergency power supply has built-in lithium battery, which is in danger of explosion during the charge and discharge process. During the aging test, when the external environment temperature rises, chemical reaction will occur inside the battery, and the internal pressure will increase, so that the volume of the chemical component mixed liquid constituting the battery will change. Once the volume suddenly changes too much and exceeds the fixed volume limit of the battery shell, the battery shell will explode because it cannot withstand the internal pressure. Some test cabinets will also create a high temperature environment in the test chamber to test its stable performance at a certain high temperature. Due to the special performance of lithium batteries and their failure rate, it is inevitable that some batteries will burn and explode during high temperature aging test. Once the emergency power supply explodes, if the emergency power supply in the test chamber is not effectively handled in time, the spread of fire will cause the emergency power supplies in the remaining test chambers of the test cabinet to be burned.

DETAILED DESCRIPTION

[0037] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0038] Example 1: Reference Figure 1-10 An emergency power supply aging test device includes a test cabinet body 1, and each test chamber 2 of the test cabinet body 1 is provided with a pop-up outlet 3 on the rear side wall, and an outward-opening door 4 is installed on the pop-up outlet 3. A transverse axis is rotatably installed on the inner wall of the top end of the outward-opening door 4, and the transverse axis is arranged parallel to the length direction of the test chamber 2. The transverse axis is fixedly connected to the test chamber 2, and the transverse axis makes the outward-opening door 4 in a closed state without external force. When the rocker 5 ejects the power supply from the pop-up outlet, the impact of the power supply will cause the outward-opening door 4 to flip upward around the transverse axis, thereby realizing the automatic opening function. A seesaw 5 is provided at the bottom of the test cabin 2, and the seesaw 5 is arranged parallel to the width direction of the test cabin 2. A sleeve 6 is fixedly installed at one end of the seesaw 5 close to the ejection outlet 3, and a hollow tube 7 is coaxially inserted in the sleeve 6. The hollow tube 7 is rotatably connected to the test cabin 2. A clamping block 8 is fixedly installed at the lower part of the end of the seesaw 5 away from the ejection outlet 3. A plug hole 9 is opened on the clamping block 8 along a direction parallel to the length of the test cabin 2, and a plug rod 10 is inserted in the plug hole 9. A first clamping plate 11 is provided on one side of the seesaw 5, and the first clamping plate is telescopically connected to the inner wall of the test cabin 2 along the length direction of the test cabin 2. The plug rod 10 is fixedly connected to the first clamping plate 11, and a second clamping plate 12 is provided on the other side of the seesaw 5, and the second clamping plate 12 is fixedly connected to the seesaw 5. The bottom of the seesaw 5 is telescopically connected to the bottom of the test cabin 2 through a compression spring 13. By providing a first clamping plate and a second clamping plate 12, the emergency power supply is clamped by the two clamping plates. If the emergency power supply is deformed, the first clamping plate will be squeezed, thereby driving the plug rod 10 connected thereto to move outward, so that the plug rod 10 loses its limiting effect on the block 8, and the compression spring 13 in the compressed state will be suddenly released to push the seesaw 5 to rise upward around the hollow tube 7, so that the seesaw 5 can eject the emergency power supply thereon toward the ejection outlet.

[0039] A storage body 14 is fixedly installed on the inner wall of the test chamber 2 on the adjacent side of the second clamping plate 12. The storage body 14 is cylindrical as a whole. The central axis of the storage body 14 is arranged perpendicular to the inner wall of the test chamber 2. A storage cavity 15 is coaxially opened in the storage body 14. The storage cavity 15 is cylindrical. A rotating shaft 16 is coaxially installed in the storage cavity 15. A storage cylinder 17 is fixedly installed on the rotating shaft 16. The rotating shaft 16 extends outward from one end close to the second clamping plate 12 and penetrates the storage body 14. The bottom end of the storage cylinder 17 is sealed and fixedly connected to the rotating shaft 16. A dilute hydrochloric acid solution is stored in the storage cylinder 17, and a sodium silicate solution is stored in the storage chamber 15.

[0040] A nozzle 18 is arranged below the storage body 14, and the nozzle 18 is arranged parallel to the central axis direction of the storage body 14. An oblique pipe 19 is arranged on the nozzle 18, and the oblique pipe 19 is connected to the storage chamber 15. The oblique pipe 19 is inclined toward the rear end of the nozzle 18, and a one-way valve is installed in the oblique pipe 19, and the one-way valve is used to prevent the gas in the nozzle 18 from entering the storage chamber 15. The front end of the nozzle 18 extends outward to the outside of the storage body 14, and a sealing plug 20 is inserted at the front end outlet of the nozzle 18. The rear end of the nozzle 18 is connected to a compressed gas supply module. By inserting the sealing plug 20 at the front end of the nozzle 18, before the nozzle 18 is not injected with compressed gas, the sealing plug 20 is subjected to less pressure due to the sodium silicate solution entering the nozzle 18, so that the sealing cover will not be flushed open. When the nozzle 18 is injected with compressed gas, the sealing cover will be flushed open by the gas in the nozzle 18 under the huge pressure of the compressed gas, so that the nozzle 18 can spray out the gas-liquid mixture.

[0041] A gear 21 is coaxially fixedly mounted on the end of the rotating shaft 16 outside the storage body 14 , and a rack 22 meshing with the gear 21 is provided on one side of the gear 21 . The rack 22 is arc-shaped and is concentrically distributed with the hollow tube 7 . The rack 22 is fixedly connected to the seesaw 5 . The reason why the rotating shaft 16 is connected to the seesaw 5 by means of a transmission connection of the gear 21 and the rack 22 is that in the process of the rotating shaft 16 driving the storage cylinder 17 to rotate and pouring the dilute hydrochloric acid solution in the storage cylinder 17 into the sodium silicate solution, the storage cylinder 17 is required to act as a stirrer to repeatedly stir the mixed solution so as to quickly mix the two solutions evenly to produce a colloid. After the seesaw 5 bounces up, due to the release of the elastic force of the compression spring 13 for a period of time, it will first be in a reciprocating telescopic state to release the energy, and finally it will recover stability. Only when the compression spring 13 recovers stability, the seesaw 5 will no longer swing. Before the seesaw 5 is stable, the seesaw 5 will drive the rotating shaft 16 to rotate back and forth through the gear 21 and the rack 22, so that the rotating shaft 16 can drive the storage cylinder 17 to repeatedly stir the solution, so that the solution can react quickly to produce a colloid.

[0042] A sealing plate 23 is fixedly mounted on the inner wall of the upper portion of the storage chamber 15. The sealing plate 23 is arc-shaped and coaxially distributed with the storage chamber 15. The top of the storage cylinder 17 is adapted to the shape of the sealing plate 23 and fits the sealing plate 23.

[0043] A first injection hole 24 is vertically formed on the sealing plate 23, and the first injection hole 24 penetrates the inner wall of the storage chamber 15 upward. A second injection hole 25 communicating with the storage chamber 15 is provided on the upper part of the storage body 14. Since the dilute hydrochloric acid solution stored in the storage cylinder 17 has high volatility, the storage cylinder 17 is provided with a good sealing performance when storing the dilute hydrochloric acid. Therefore, a circular arc-shaped sealing plate 23 is provided. When the storage cylinder 17 rotates to the uppermost position following the rotating shaft 16, the top of the storage cylinder 17 is tightly fitted with the sealing plate 23, so that the dilute hydrochloric acid solution stored in the storage cylinder 17 can be stored under a good sealing ring.

[0044] The front end outlet of the nozzle 18 is arranged toward the top of the test chamber 2, and a check valve is built into the rear end of the nozzle 18, and the check valve is used to prevent the liquid in the nozzle 18 from entering the compressed gas supply module.

[0045] A plurality of magnetic sealing strips are fixed to the inner surface of the outward opening door 4, and a plurality of magnetic attraction strips corresponding to the magnetic sealing strips are fixed to the edges around the ejection outlet 3.

[0046] The present invention also provides an emergency power supply aging test method, comprising the following steps:

[0047] S1, press the seesaw 5 downward, and the seesaw 5 presses the compression spring 13 downward to the lowest point, so that the seesaw 5 is in a horizontal state, and then insert the insertion rod 10 into the socket 9 in the card block 8, and then place the emergency power supply to be tested on the seesaw 5, and the emergency power supply is clamped by the first clamping plate 11 and the second clamping plate 12;

[0048] S2, injecting dilute hydrochloric acid solution into the storage cylinder 17 through the first injection hole 24, injecting sodium silicate solution into the bottom of the storage chamber 15 through the second injection hole 25, and then sealing the first injection hole 24 and the second injection hole 25;

[0049] S3, connecting the emergency power supply to the built-in charge and discharge test system of the test chamber 2, and then starting the charge and discharge test system to perform an aging test on the emergency power supply;

[0050] S4. After the test is completed, disconnect the emergency power supply from the built-in charge and discharge test system of test chamber 2 and unplug the emergency power supply.

[0051] Example 2: Reference Figure 11-14As another preferred embodiment of the present invention, the difference from Embodiment 1 is that the compressed gas supply module includes a docking cavity 26, an air outlet 27, and an air outlet pipe 28. One end of the hollow tube 7 is sealed, and the other end of the hollow tube 7 is connected to the compressed gas storage device. The air outlet 27 is provided on the inner wall of the hollow tube 7 covered by the sleeve 6. The air outlet 27 is provided on the inner wall of the sleeve 6 and a docking cavity 26 is provided corresponding to the air outlet 27. The sleeve 6 is provided with an air outlet pipe 28 connected to the docking cavity 26, and the rear end of the nozzle 18 is connected to the air outlet pipe 28. The compressed gas supply module is integrated with the seesaw 5 and the hollow tube 7, so that after the seesaw 5 bounces up, due to the release of the elastic force of the compression spring 13 for a period of time, it will first be in a reciprocating telescopic state to release the energy, and finally it will return to stability. Only when the compression spring 13 evaporates and stabilizes, the seesaw 5 no longer swings, and the docking cavity 26 on the sleeve 6 connected to the seesaw 5 will be aligned with the air outlet 27, and the hollow tube 7 can be connected with the nozzle 18 at this time. In this way, after the seesaw 5 bounces up, the hollow tube 7 will not be immediately connected to the nozzle 18, so that the nozzle 18 will not immediately inject compressed gas to spray the solution in the storage body 14, so that the solution in the storage can get sufficient mixing time.

[0052] The overall workflow of the present invention is as follows:

[0053] S1. During the power aging test, if the emergency power supply is overheated, the shell of the emergency power supply will expand outward and deform under the pressure of the deformed battery cell inside. At this time, the shell of the emergency power supply will push the first clamping plate 11 outward, and the first clamping plate 11 drives the plug 10 to disengage from the socket 9 on the card block 8 outward. At this time, the seesaw 5 loses its limit, and the compression spring 13 will suddenly release, pushing the seesaw 5 upward, and the seesaw 5 ejects the emergency power supply on it through the ejection outlet 3. A fire water pool can be set in advance on the ground below the ejection outlet 3 to use the large amount of liquid in the fire water pool to slow down the heat release of the emergency power supply;

[0054] In order to avoid explosion after deformation of the emergency power supply and ignite the remaining objects in the test chamber 2, during the process of the seesaw 5 being tilted, on the one hand, the seesaw 5 will drive the rack 22 to drive the gear 21 to rotate, the gear 21 will drive the shaft 16 to rotate, and the shaft 16 will drive the storage cylinder 17 to swing back and forth. During the swinging process, the storage cylinder 17 will be in an inverted state, and the dilute hydrochloric acid solution stored therein will be poured into the sodium silicate solution in the storage cavity 15 in the storage body 14, and the swinging storage cylinder 17 will stir the mixed liquid to accelerate the reaction of the two liquids so that the two solutions can quickly produce silicate hydrogel; on the other hand, the seesaw 5 will drive the sleeve 6 to rotate so that the ground alignment cavity on the sleeve 6 is aligned with the air outlet 27 on the hollow tube 7 At this time, the compressed gas storage device connected to the hollow tube 7 will inject the compressed gas into the aiming cavity through the hollow tube 7, and then inject it into the nozzle 18 through the outlet pipe 28. The silicate hydrogel in the storage cavity 15 will enter the nozzle 18 through the oblique tube 19, and follow the compressed gas ejected from the nozzle 18 to be ejected into the test chamber 2. The ejected silicate hydrogel will decompose at high temperature to release water vapor and carbon dioxide. These gases can isolate flames and air, thereby preventing the fire from spreading in the test chamber 2. In addition, the silicon dioxide layer formed after the decomposition of the silicate hydrogel can cover the surface of the burning object to form a protective film to isolate oxygen, thereby achieving a fire prevention effect, thereby minimizing the damage to the test cabinet after the emergency power supply explodes.

[0055] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
