Description

Technical Field

[0001] The utility model belongs to the technical field of hydrogen fuel cell collision detection workbenches, and in particular relates to a hydrogen fuel cell collision detection workbench. Background Art

[0002] A hydrogen fuel cell is a power generation device that can directly convert the chemical energy of hydrogen and oxygen into electrical energy. During the entire process of converting chemical energy into electrical energy, only gaseous water is produced, and no other pollutants are generated. It is a perfect automotive energy source in the future. However, due to the poor stability of hydrogen, it is easy to burn and explode when used carelessly. Therefore, during the quality inspection of hydrogen batteries, collision detection of hydrogen batteries is one of the important links of hydrogen fuel cells.

[0003] In the collision detection process of hydrogen fuel cells, the hydrogen fuel cell collision detection workbench, as an experimental equipment, is an important device for collision detection of hydrogen fuel cells. After searching, a Chinese patent discloses a hydrogen fuel cell collision detection workbench (publication number CN220304796U). The workbench is provided with a protective cover on the outside of the placement frame through the setting of a protective cover, a bottom plate, an annular groove, a support plate and a downward moving part. The height of the protective cover is higher than the placement frame, and the protective cover can be raised and lowered. The knob is rotated, and the knob drives the rotating plate to rotate. The bottom of the rotating plate contacts the slope of the extrusion block, and the bottom plate drives the protective cover to move downward, which reduces the splashing of parts without affecting the placement of the battery and protects the internal equipment.

[0004] However, since battery fires often occur during collision testing, the collision detection workbench still has the following problems when in use:

[0005] 1. The above-mentioned collision detection workbench uses dry powder for fire extinguishing. After the dry powder is sprayed, the scattered dry powder will float inside the device, which is difficult and troublesome to clean, affecting subsequent use;

[0006] 2. The above-mentioned collision detection workbench performs dry powder spraying protection after the fire occurs, which is triggered slowly, making it more difficult to extinguish the fire, and is likely to cause the hydrogen fuel cell to explode, resulting in greater losses.

[0007] Therefore, the utility model proposes a hydrogen fuel cell collision detection workbench to solve the problems existing in the above-mentioned prior art. Utility Model Content

It solves the problem that fires often occur during battery collision tests, and rapid fire extinguishing is performed with dry powder. After the dry powder is sprayed, the scattered dry powder is difficult to clean up, which is troublesome.

[0048] (III) Beneficial effects

[0049] Compared with the prior art, the utility model provides a hydrogen fuel cell collision detection workbench, including a mounting table, the inner wall of which is slidably matched with a storage box. When in use:

[0050] 1. Through the setting of the protective isolation cover, the collision test of the hydrogen fuel cell is carried out on the collision assembly. When the hydrogen fuel cell burns due to the impact and extrusion of the collision assembly, it can be quickly covered on the battery storage box after being triggered to isolate the air and perform physical fire prevention, effectively avoiding the problems of difficulty in cleaning the battery storage box, slow triggering and poor fire extinguishing effect in the later stage;

[0051] 2. Through the setting of the covering fire extinguishing mechanism, the battery can be impact tested. The infrared sensor will detect the heat dissipation. When short-circuited, the infrared sensor will send an electrical signal to the detaching and falling assembly. The detaching and falling assembly will detach the protective isolation cover from the pushing part of the reset and jacking assembly. The protective isolation cover will fall quickly to cover the surface of the storage box to isolate the air and prevent the battery from burning. After the battery is short-circuited and melted, it will cool down. Through the reset jacking assembly, the detaching and falling assembly will be connected again, and then the reset jacking assembly will be started to push the protective isolation cover up, so that the battery can be taken out, which is safer;

[0052] 3. Through the connection between the electromagnet and the infrared sensor, when the heat is emitted before a short circuit occurs and a fire occurs, the reset jacking assembly is automatically controlled to drop the protective isolation cover, quickly eliminating the fire hazard; achieving the purpose of rapid and automatic fire extinguishing and heat insulation, avoiding explosion, and ensuring the safety of the experiment.

[0060] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0061] Example 1: Please refer to Figure 1-6 , the utility model provides a technical solution:

[0062] A hydrogen fuel cell collision detection workbench, comprising:

[0063] Mounting table 1;

[0064] A battery storage box 2 is slidably mounted in the mounting platform 1 and is used to store batteries during testing;

[0065] The protective isolation cover 3 is arranged in the mounting platform 1 on the upper side of the battery storage box 2 and is used in conjunction with the battery storage box 2. A collision component 4 is fixedly connected to the upper end of the protective isolation cover 3.

[0066] The covering fire extinguishing mechanism 5 is arranged on one side of the mounting platform 1 and is used in conjunction with the protective isolation cover 3 to control the rapid descent of the protective isolation cover 3 when in use to extinguish the fire in the battery storage box 2;

[0067] The infrared sensor 6 is arranged on one side of the mounting platform 1 and is used in conjunction with the covering fire extinguishing mechanism 5 to control the triggering of the covering fire extinguishing mechanism 5 so that the protective isolation cover 3 can be quickly lowered when a fire occurs;

[0068] Specifically, when in use: first, fix the battery to be tested in the battery storage box 2, and use the collision assembly 4 to perform a collision test on the hydrogen fuel cell 7. When the hydrogen fuel cell burns due to the impact and squeezing of the collision assembly 4, the infrared sensor 6 detects a large amount of battery heat dissipation. At this time, the infrared sensor 6 sends an electrical signal to the covering fire extinguishing mechanism 5, and the covering fire extinguishing mechanism 5 quickly releases the protective isolation cover 3, so that the protective isolation cover 3 quickly falls to the upper surface of the covering storage box 2 to isolate the air to prevent the battery from burning.

[0069] As a preferred embodiment, an observation window is provided on one side of the protective isolation cover 3, so that the melting of the internal battery can be observed. When the battery is stable, it is convenient to judge and adjust the removal.

[0070] As a preferred embodiment, the impact assembly 4 is composed of an impact cylinder and a front impact hammer, and the front impact hammer is controlled by the impact cylinder to perform an impact test on the batteries in the storage box 2.

[0071] As a preferred implementation scheme, for the personnel in this technical field, the infrared sensor 6 and the collision assembly 4 are both prior art and will not be further described here.

[0072] Example 2: Please refer to Figure 1-3 , the covering fire extinguishing mechanism 5 comprises:

[0073] The reset and lifting assembly 501 is arranged on one side of the mounting platform 1 and is used to lift the protective isolation cover 3 after the fire is extinguished;

[0074] The disengagement drop assembly 502 is arranged on one side of the reset lift assembly 501 and is used to receive the control command of the infrared sensor 6 and quickly release the protective isolation cover 3;

[0075] Specifically, when installing the battery, the storage box 2 can be taken out, and the battery can be fixed in the storage box 2 by bolts, and then the storage box 2 can be put back, and the collision component 4 can be started to perform an impact test on the battery; when the battery short-circuits, the infrared sensor 6 detects a large amount of heat dissipated from the battery. At this time, the infrared sensor 6 sends an electrical signal to the detachment and falling component 502, and the detachment and falling component 502 detaches the protective isolation cover 3 from the pushing part of the reset lifting component 501, and the protective isolation cover 3 falls quickly to cover the surface of the storage box 2 to isolate the air and prevent the battery from burning, and wait for the battery to cool down after it melts; by descending the reset lifting component 501, the detachment and falling component 502 is connected again, and then the reset lifting component 501 is started to push the protective isolation cover 3 to rise, and the battery can be taken out more safely.

[0076] Example 3: Please refer to Figure 4 and Figure 5 , the reset and lift assembly 501 comprises:

[0077] Motor 5011, fixedly mounted on one side of mounting platform 1;

[0078] The lead screw 5012 is arranged at the power output end of the motor 5011;

[0079] The T-shaped push slider 5013 is threadedly connected to the lead screw 5012 and is detachably connected to the protective isolation cover 3 by disengaging the drop assembly 502;

[0080] Specifically, the protective isolation cover 3 can be pushed to a predetermined covering height by resetting the lifting component 501, and can be quickly started to perform fire prevention and fire extinguishing after being triggered by the detached falling component 502; when the fire extinguishing is completed, the motor 5011 is started, and the motor 5011 drives the lead screw 5012 to rotate, and the lead screw 5012 drives the T-shaped push slider 5013 to descend, and at this time, the metal adsorption block 5026 is pulled to fit with the electromagnet 5027, and the electromagnet 5027 is energized to adsorb and connect, and at this time, the motor 5011 is reversed, and the lead screw 5012 drives the upper end of the T-shaped push slider 5013 to lift the protective isolation cover 3, and the internal battery can be taken out.

[0081] As a preferred embodiment, the side end of the mounting platform 1 is also fixedly connected to a slide bar 5014, and the side end of the protective isolation cover 3 is fixedly connected to a limit slider 5015, and the limit slider 5015 is slidably connected to the surface of the slide bar 5014;

[0082] Specifically, when the screw 5012 rotates to drive the T-shaped push slider 5013 and the protective isolation cover 3 to rise and fall, the T-shaped push slider 5013 is likely to shake along with the rotation of the screw 5012. When the T-shaped push slider 5013 rises and drives the protective isolation cover 3 to move, the sliding cooperation of the slide bar 5014 and the limiting slider 5015 limits the sliding of the protective isolation cover 3, making the sliding of the protective isolation cover 3 more stable and not easy to tilt, and can stably cover the surface of the storage box 2.

[0083] As a preferred embodiment, the upper end of the sliding rod 5014 is also fixedly connected to a rotating seat 5016, and the lead screw 5012 is rotatably connected to the rotating seat 5016;

[0084] Specifically, when the lead screw 5012 rotates, the upper end of the lead screw 5012 is prone to swing, and the rotation of the lead screw 5012 is limited by the rotating seat 5016, so that the lead screw 5012 is more stable and less likely to swing when rotating.

[0085] Example 4: Please refer to Figure 5 and Figure 6 , the disengagement and falling assembly 502 comprises:

[0086] A connecting seat 5021, wherein the connecting seat 5021 is fixedly disposed on one side end of the protective isolation cover 3, and a T-shaped groove is disposed on the connecting seat 5021;

[0087] I-shaped block 5022, said I-shaped block 5022 is slidably installed in the connecting seat 5021, and a "T"-shaped block at one end of the I-shaped block 5022 is used in conjunction with a T-shaped slot on the connecting seat 5021, and slides along the T-shaped slot; the "T"-shaped block at the other end of the I-shaped block 5022 is used in conjunction with a slide groove 5025 provided on the T-shaped pushing slider 5013, and slides along the slide groove 5025;

[0088] A pull rod 5024 is movably installed in the slide groove 5025 and fixedly connected to the I-shaped block 5022. The outer end of the pull rod 5024 is also fixedly connected to a metal adsorption block 5026. The metal adsorption block 5026 is used in conjunction with an electromagnet 5027 arranged on the outer end of the T-shaped pushing slider 5013. The electromagnet 5027 is adsorbed on the surface of the metal adsorption block 5026. The electromagnet 5027 can be connected to the infrared sensor 6. The infrared sensor 6 is electrically connected to the electromagnet 5027. A spring 5023 is also sleeved on the outer side of the pull rod 5024. The two ends of the spring 5023 are respectively connected to the pull rod 5024 and the T-shaped pushing slider 5013;

[0089] Specifically, under normal conditions, the I-shaped block 5022 is engaged in the T-shaped groove on the connecting seat 5021 to fix the protective isolation cover 3 so that the protective isolation cover 3 is suspended on the upper side of the storage box 2. At this time, the spring 5023 is stretched. When the infrared sensor 6 detects that the battery is overheated, the electromagnet 5027 is powered off, and the electromagnet 5027 loses the adsorption effect with the metal adsorption block 5026. Under the resetting force of the spring 5023, the I-shaped block 5022 and the pull rod 5024 are driven to move outward together, so that the connection between the I-shaped block 5022 and the connecting seat 5021 is lost, and the protective isolation cover 3 is disengaged from the push, and quickly falls to cover the surface of the storage box 2, isolating the air and quickly extinguishing the fire until the battery melts and the circuit is broken. At this time, it can be taken out more safely.

[0090] As a preferred implementation scheme, for those skilled in the art, electromagnet 5027 is prior art and will not be described in detail herein.

[0091] When the hydrogen fuel cell collision detection workbench of the utility model is used:

[0092] When installing the battery, the storage box 2 can be taken out, and the battery can be installed in the storage box 2 by bolts, and then the storage box 2 can be put back, and the collision component 4 can be started to perform an impact test on the battery. When a short circuit occurs, the infrared sensor 6 will detect a large amount of heat dissipation. At this time, the infrared sensor 6 transmits an electrical signal to cut off the power of the electromagnet 5027. When the electromagnet 5027 is cut off, the spring 5023 relaxes. At this time, the spring 5023 pushes the I-shaped block 5022 to disengage in the T-shaped pushing slider 5013, so that the protective isolation cover 3 is disengaged and pushed. The protective isolation cover 3 falls and covers the surface of the storage box 2 to isolate the air and quickly extinguish the fire until the battery melts and breaks the circuit. At this time, it is safer to take it out. When the fire is extinguished, The fire is completed, and the motor 5011 is started at this time. The motor 5011 drives the lead screw 5012 to rotate, and the lead screw 5012 drives the T-shaped push slider 5013 to descend. At this time, the metal adsorption block 5026 is pulled to fit with the metal adsorption block 5026, and the electromagnet 5027 is energized to adsorb and connect. At this time, the motor 5011 is reversed, and the lead screw 5012 drives the upper end of the T-shaped push slider 5013 to lift the protective isolation cover 3. At this time, the internal battery can be taken out more safely, and the overall fire extinguishing is completed at this time. During the whole process, no fine dry powder will appear, which is convenient for subsequent experiments. At the same time, the device can isolate the air in a very short time when a short circuit occurs, preventing combustion and reducing the possibility of experimental deflagration.
