Description
Technical Field
[0001] This application relates to the field of battery technology, and in particular to vibration table fire-fighting devices and vibration testing equipment. Background Technology
[0002] As the power source for vehicles, power batteries are installed at the bottom of the vehicle and travel with it through various complex road conditions. Their unique application requires them to pass vibration testing. With the increasing frequency of electric vehicle fires, consumers are paying close attention to battery safety. Vibration testing simulates the entire lifespan of a battery through several hours of vibration. During testing of batteries in the research and development stage, instability could cause samples to catch fire.
[0003] Existing vibration tables generally use tooling and bolts to fix battery samples to the vibration table surface. This rigid connection makes it impossible to move the sample out of the vibration table after the battery catches fire. The fire can only be extinguished on the table surface with fire-fighting water, which has low extinguishing efficiency and poses a safety hazard. The continuous high temperature may damage the vibration table, and there is a risk of water ingress into the electrical components of the vibration system. Utility Model Content
[0004] This application provides a vibration table fire-fighting device and vibration testing equipment to solve the problems of low fire extinguishing efficiency of vibration tables and water ingress risk to electrical components of vibration systems in the prior art, which pose safety hazards.

The enclosure has a first position and a second position. The enclosure can move along a preset direction to the first position so that the enclosure is lower than the vibration table. The enclosure can move along a preset direction to the second position so that the enclosure is higher than the vibration table. The preset direction is the height direction of the vibration table.

[0014] The traction cable is wound around the first pulley, and the free end of the traction cable passes over the second pulley. The traction cable has a fixing part that connects to the enclosure cover.
[0015] The drive unit is connected to the free end of the traction cable.
[0016] In one possible design, a water injection pipe is also included, located above the vibration table.
[0017] In one possible design, a smoke sensor is also included, which is positioned around the vibration table and is connected to the valve signals of the drive unit and the water injection pipe.
[0018] In one possible design, a photoelectric sensor is also included, which is located on the side of the support rod near the enclosure and is connected to the drive unit via a signal.
[0019] In one possible design, a liquid level sensor is also included, which is mounted on a vibration table and connected to the valve signal of the water injection pipe.

[0024] In one possible design, the elastic element is a torsion spring, and the inner wall of the enclosure is provided with a rotating shaft. The torsion spring and the limiting block are respectively sleeved on the rotating shaft. One end of the torsion spring abuts against the inner wall of the enclosure, and the other end abuts against the limiting block. The torsion spring can make the limiting block rotate around the rotating shaft toward the limiting platform.
[0025] On the other hand, this application also provides a vibration testing device, including the vibration table fire-fighting device as described above.
[0026] The beneficial effects of this application are as follows:
[0027] The vibration table fire-fighting device of this application is equipped with a water storage tank and a baffle with a sliding seal connection. The baffle has a first position and a second position. During normal testing, the baffle can be lowered to the first position, so that the baffle is lower than the vibration table and does not affect the observation of the test sample during the vibration test. When the test sample on the vibration table catches fire, the baffle can be raised to the second position in time, so that the baffle is higher than the vibration table. This allows it to form a sealed container with the water storage tank to hold water together, so that the water level rises rapidly to submerge the test sample. This improves the fire-fighting efficiency and also prevents fire water from flowing to other parts of the vibration body, prevents water from entering the electrical components of the vibration body, and eliminates safety hazards.

[0037] The technical solutions of this application will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0038] The following is combined Figures 1-5 This describes the vibration table fire-fighting device provided in the embodiments of this application.
[0039] Reference Figure 1-4As shown in the figure, this application provides a vibration table fire-fighting device. The device includes a base 100, a water storage tank 300, and a protective cover 400. The base 100 has an internal mounting cavity, in which the vibration body and the water storage tank 300 are both disposed. The water storage tank 300 is located below the vibration table 200 and is a cylindrical shape with an open top for holding water. In some embodiments, the bottom of the water storage tank 300 also has a mounting hole, through which a support column below the vibration table 200 passes. The support column is connected to the motor of the vibration body for transmission, enabling the vibration of the vibration table 200. The outer wall of the water storage tank 300 is mounted to the outer shell of the vibration body using bolts. In some embodiments, a sealing sleeve is fitted onto the outer wall of the support column corresponding to the mounting hole, forming a sealed bottom for the water storage tank 300 to prevent water leakage between the support column and the mounting hole. The protective cover 400 is located below the vibration table 200. Around the 0, the enclosure 400 is a vertically continuous ring. The inner wall of the enclosure 400 slides and seals with the outer wall of the water storage tank 300. For example, the inner wall of the enclosure 400 and the outer wall of the water storage tank 300 achieve a seal through a gap fit; or, for example, a sealing ring is provided between the inner wall of the enclosure 400 and the outer wall of the water storage tank 300, and the inner wall of the enclosure 400 and the outer wall of the water storage tank 300 achieve a sliding seal through the sealing ring. During the process of the enclosure 400 moving up and down along the outer wall of the water storage tank 300, water can be prevented from leaking out from the gap. The enclosure 400 has a first position (the position during normal testing) and a second position (the position during fire extinguishing). The enclosure 400 can move along a preset direction to the first position so that the enclosure 400 is lower than the vibration table 200, and the enclosure 400 can move along a preset direction to the second position so that the enclosure 400 is higher than the vibration table 200. The preset direction is the height direction of the vibration table 200.
[0040] Using the technical solution provided in the above embodiments, during normal testing, the enclosure 400 can be lowered to the first position, making the enclosure 400 lower than the vibration table 200, so as not to affect the observation of the test sample in the vibration test; when the test sample on the vibration table 200 catches fire, the enclosure 400 can be raised to the second position in time, making the enclosure 400 higher than the vibration table 200, so that it can form a sealed container with the water storage tank 300 to hold water together, so that the water level can rise rapidly to submerge the test sample, improve the fire extinguishing efficiency, and at the same time prevent the fire water from flowing to other positions of the vibration body, prevent water from entering the electrical components of the vibration body, and eliminate safety hazards.
[0041] Reference Figure 1As shown, the device also includes a lifting assembly, which is mounted on the base 100. The lifting assembly can drive the enclosure cover 400 to rise or fall along the height direction of the vibration table 200, moving it to a first position or a second position. In some specific embodiments, the lifting assembly includes a support rod 510, a first pulley 520, a second pulley 530, a traction cable 540, and a driving member 550. The support rod 510 is vertically mounted on the base 100, and the first pulley 520 is mounted on the base 100. The second pulley 530 is mounted on the upper section of the support rod 510, and the position of the second pulley 530 is higher than that of the first pulley 520. The traction cable 540 is wound around the first pulley 520, and the free end of the traction cable 540 passes over the second pulley 530 and is connected to the driving member 550. The traction cable 540 has a connection with the enclosure cover 400. The fixing part of the 00 connection; in some specific embodiments, the fixing part is a fixing seat, which is welded to the traction cable 540. The fixing seat is connected or welded to the connecting ear of the outer wall of the enclosure 400 through a snap-fit structure. The traction cable 540 between the first pulley 520 and the second pulley 530 is vertically arranged, and the fixing part is located on the traction cable 540 between the first pulley 520 and the second pulley 530. The driving component 550 is a servo motor. When the servo motor drives the free end of the traction cable 540 to wrap around the output shaft, the fixing part on the traction cable 540 will drive the enclosure 400 to move up and down.
[0042] In other embodiments, the lifting assembly may also employ a rack and pinion drive. For example, a rack is vertically mounted on the base 100, the output end of the servo motor is connected to the gear, the gear meshes with the vertically mounted rack, driving the rack to rise and fall, and the connecting lugs on the outer wall of the enclosure 400 are welded or bolted to the rack, so that the enclosure 400 can rise and fall under the drive of the rack.
[0043] Reference Figure 1In some embodiments provided in this application, the device further includes a water injection pipe 600, located above the vibration table 200. The beginning of the water injection pipe 600 is connected to a water tank. When the test sample catches fire, the valve of the water injection pipe 600 is opened to pour water onto the vibration table 200. In some specific embodiments, a smoke sensor 710 is also included. The smoke sensor 710 is disposed around the vibration table 200. In some specific embodiments, the smoke sensor 710 is disposed near the end of the water injection pipe 600 to detect whether there is smoke below in a timely manner. The smoke sensor 710 is connected to the drive unit 550 and the valve of the water injection pipe 600, wherein the valve of the water injection pipe 600 is a solenoid valve. When the smoke sensor 710 detects smoke, it sends signals to the drive unit 550 and the valve of the water injection pipe 600. The drive unit 550 drives the traction cable 540, which in turn drives the enclosure cover 400 to move up and down. At the same time, the valve of the water injection pipe 600 opens, and the water in the water injection pipe 600 flows downward into the sealed space enclosed between the vibration table 200, the enclosure cover 400, and the water storage tank 300.
[0044] Reference Figure 1 As shown, in some embodiments provided in this application, the device further includes a photoelectric sensor 720. The photoelectric sensor 720 is disposed on the side of the support rod 510 near the enclosure 400, and is signal-connected to the drive unit 550. When the enclosure 400 rises to the second position, the enclosure 400 will block the photoelectric sensor 720, thereby the photoelectric sensor 720 sends a signal to the drive unit 550, and the drive unit 550 stops driving the traction cable 540 to move, keeping the enclosure 400 in the second position.
[0045] Reference Figure 1 As shown, in some embodiments provided in this application, the device further includes a liquid level sensor 730, which is mounted on the vibration table 200 and is connected to the valve of the water injection pipe 600. During the process of the water injection pipe 600 continuously injecting water into the sealed space enclosed between the vibration table 200, the enclosure 400, and the water storage tank 300 when the enclosure 400 rises to the second position, the liquid level sensor 730 can detect the water depth. When the water reaches a certain depth, the liquid level sensor 730 sends a signal to the valve of the water injection pipe 600, the valve of the water injection pipe 600 closes, and the water injection pipe 600 stops injecting water.
[0046] Reference Figure 1 , Figure 5As shown, in some embodiments provided in this application, the device further includes a limiting component, which includes a sliding groove 810, a limiting block 820, and an elastic member 830. The sliding groove 810 is formed on the outer wall of the water storage tank 300, with the groove opening facing upwards. The inner wall of the sliding groove 810 has a limiting platform 811 near the groove opening. The limiting block 820 is disposed on the inner wall of the enclosure 400, and the elastic member 830 enables the limiting block 820 to move toward the limiting platform 811 and be engaged at the limiting platform 811. In some specific embodiments, the elastic element 830 is a torsion spring 831, and the inner wall of the enclosure 400 is provided with a rotating shaft 840. The torsion spring 831 and the limiting block 820 are respectively sleeved on the rotating shaft 840. One end of the torsion spring 831 abuts against the inner wall of the enclosure 400, and the other end abuts against the limiting block 820. The end of the limiting block 820 extends outward to form a protruding edge. The torsion spring 831 enables the end of the limiting block 820 to rotate around the rotating shaft 840 toward the limiting platform 811. When the enclosure cover 400 is in the first position, the limiting block 820 is located in the slide groove 810; when the enclosure cover 400 rises to the second position, the limiting block 820 moves up to the opening of the slide groove 810, and the limiting block 820 rotates under the elastic force of the torsion spring 831. The protruding edge at the end of the limiting block 820 abuts against the limiting platform 811, thereby limiting the position of the enclosure cover 400.
[0047] In one embodiment, the elastic element 830 can also be a linear spring. One end of the linear spring abuts against the inner wall of the enclosure 400, and the other end abuts against the limiting block 820. When the enclosure 400 is in the first position, the limiting block 820 is located in the slide groove 810. When the enclosure 400 rises to the second position, the limiting block 820 moves up to the opening of the slide groove 810. The limiting block 820 rotates under the elastic force of the linear spring, and the protruding edge at the end of the limiting block 820 abuts against the limiting platform 811, thereby limiting the position of the enclosure 400.
[0048] The working process of the vibration table fire suppression device in this application is as follows:
[0049] When a sample is ready for vibration testing, it needs to be fixed to the vibration table 200 using a fixture. At this time, in order to avoid affecting the observation of the sample's condition, the enclosure 400 should be lowered to the first position. When the sample fails, combustible gas or smoke floats upward. After the smoke sensor 710 detects the smoke, it sends a signal to the drive unit 550. After the drive unit 550 is activated, it pulls the traction cable 540 to raise the enclosure 400 to the second position. At the same time, the smoke sensor 710 sends a signal to the valve of the water injection pipe 600, causing the valve of the water injection pipe 600 to open and inject fire water into the location of the failed battery.
[0050] When the enclosure cover 400 is raised to the set height and reaches the second position, the enclosure cover 400 will block the photoelectric sensor 720, causing the photoelectric sensor 720 to trigger protection, thereby interrupting the power supply to drive the vibration table 200, effectively avoiding more serious electrical accidents caused by battery fire and water injection; at the same time, the limit block 820 will pop out to prevent the enclosure cover 400 from sliding down due to power failure.
[0051] In this state, the vibration table 200, the enclosure 400, and the water storage tank 300 form a sealed cavity, allowing fire water to be continuously injected until it completely submerges the sample. When the water level reaches the upper end of the enclosure 400, the level sensor 730 sends a signal to the valve of the water injection pipe 600, causing the valve of the water injection pipe 600 to close, blocking the continued injection of fire water and preventing fire water overflow from causing damage to the equipment.
[0052] The vibration table fire-fighting device of this application has the following beneficial effects:
[0053] 1. The enclosure can be raised and lowered automatically. Before failure, it does not affect normal testing and observation. In case of failure, it will automatically trigger the enclosure to rise, fill with water, and stop filling with water. No personnel need to operate it at close range, which effectively reduces the possibility of personal injury.
[0054] 2. It occupies little space, does not require separate arrangement, and has a low cost.
[0055] 3. It is reusable, has a low cost, and can effectively protect equipment from damage.
[0056] 4. It is highly efficient and responds promptly to sudden failure events, which can effectively reduce the possibility of equipment damage.
