Description

Technical Field

[0001] The invention belongs to the technical field of fire safety, and in particular relates to a fire extinguishing and explosion suppression test box. Background Art

[0002] Batteries, especially lithium-ion batteries, are currently the primary energy storage and conversion components. Their advantages, such as long cycle life, lack of memory effect, ease of use, high energy storage capacity, and minimal environmental impact, have garnered significant market attention and led to their application in various sectors, particularly in new energy electric vehicles. However, as a high-energy carrier, lithium-ion batteries pose a fundamental and core safety concern. Fire accidents can be difficult to control and address.

[0003] Energy storage containers using lithium-ion batteries as energy storage media have come into being. Lithium-ion battery energy storage containers are widely used due to their stable power supply, large power supply, and ease of rapid movement. However, thermal abuse of lithium-ion batteries and external mechanical misactions can still cause internal thermal runaway of the battery. When the heat generated by the internal chemical reaction of the battery in thermal runaway cannot be dissipated in time, the safety valve will rupture, causing the battery to bulge, smoke, and burn. After thermal runaway, lithium-ion batteries can release a large amount of heat and produce a large amount of flammable gas, which can quickly cause a fire and threaten people and property. Lithium-ion batteries catch fire quickly, the fire is large, and the fire temperature is high. It may also be accompanied by the risk of explosion. After the open flame is extinguished, re-ignition may occur. During battery storage, once a lithium-ion battery cell undergoes thermal runaway, the large amount of heat generated will heat the surrounding batteries, thereby causing thermal runaway of adjacent batteries. Research on thermal runaway transmission and thermal runaway fire extinguishing of lithium-ion batteries is particularly important. Therefore, the research and development of a new battery fire extinguishing test platform has objectively become an urgent need. Summary of the Invention

During the actual test, two of the explosion suppressors 125 perform explosion suppression operations, and the other two explosion suppressors 125 are reserved for backup; the first guide rail 111 is arranged at the top of the box body 101; the installation A guide block 117 is provided on the mounting block 116, and the guide block 117 is connected to the first guide rail 111; the explosion suppressor 125 is connected to the mounting block 116, and the first guide rail 111 is slidably connected to the top of the box body 101. An opening for the first guide rail 111 to extend out is provided on the side wall of the box body 101, and the opening is covered with a sealing plate 103, which is slidably connected to the side wall of the box body 101. The sealing plate 103 is controlled by an electric device so that the sealing plate 103 can rise relative to the opening to open the opening, so as to quickly replace the explosion suppressor 125; when conducting an explosion experiment, the sealing plate 103 closes the opening to prevent the impact of the explosion from rushing out from the opening.

[0047] The inner wall of the chamber 101 is provided with an explosion-proof layer made of high-strength, high-temperature-resistant materials. This layer can effectively resist the impact and high temperature generated by explosions, protecting the structural integrity and safety of the experimental chamber. The chamber door 102 is provided with a transparent observation window made of explosion-proof glass, which allows for convenient observation of the experimental process while ensuring safety.

[0048] A second guide rail 112 is provided on the top of the box body 101, and a second guide rail 112 is provided on both sides of the first guide rail 111 respectively. A first slider 1111 is provided on the side wall of the first guide rail 111, and a first slide groove for the first slider 1111 to move is provided on the second guide rail 112. An explosion-proof box 113 is provided on one side of the second guide rail 112 on one side of the first guide rail 111, and an electric push rod 114 is provided in the explosion-proof box 113. An extension rod 1112 is provided on the first slider 1111 on the side that is connected to the explosion-proof box 113, and the extension rod 1112 passes through the first slide groove. The piston rod of the electric push rod 114 is connected to the extension rod 1112; the electric push rod 114 provides power for the movement of the first guide rail 111, so that the first guide rail 111 can drive the mounting block 116 to extend out of the box body 101 from the opening to facilitate installation and replacement of the explosion suppressor 125.

[0049] The mounting block 116 is provided with a first motor 120, and the output shaft of the first motor 120 is provided with a first transmission wheel 121, which is against the side wall of the first guide rail 111. The transmission wheel and the first guide rail 111 are used to cooperate with each other so that the first motor 120 drives the first transmission wheel 121 to rotate and drives the mounting block 116 to move on the first guide rail 111, thereby adjusting the position of the explosion suppressor 125 so as to test the performance of the explosion suppressor 125 from multiple angles; the guide block 117 is provided with a first movable groove The first movable slot is equipped with a fixed block 118 and a first electromagnet. A first return spring 119 is mounted on the fixed block 118. The first guide rail 111 is provided with multiple fixed slots corresponding to the fixed block 118. When the mounting block 116 needs to be driven to move, the first electromagnet is energized to generate magnetic attraction to the fixed block 118, causing the fixed block 118 to overcome the elastic force of the first return spring 119 and move toward the first electromagnet. The fixed block 118 is then removed from the fixed slot, moving the explosion suppressor 125 to the designated desired position for testing. After the explosion suppressor 125 is positioned, the first electromagnet is de-energized. At this time, the fixed block 118 is reset by the elastic force of the first return spring 119 and inserted into the fixed slot, thereby fixing the mounting block 116 and the explosion suppressor 125 in a specific position on the first guide rail 111. By setting up structures such as the fixing block 118, the first electromagnet and the first return spring 119, the position of the explosion suppressor 125 can be quickly fixed and adjusted, thereby improving the convenience and efficiency of the experiment. At the same time, the cooperation between the fixing block 118 and the fixing groove can avoid movement of the mounting block 116 when installing and replacing the explosion suppressor 125.

[0050] Two adjacent first guide rails 111 are connected via a fifth guide rail 115 , so that the mounting block 116 can move on the top of the entire test space, allowing the explosion suppressor 125 to be adjusted at more angles.

[0051] A connecting plate 122 is provided at the bottom of the mounting block 116, a plurality of first connecting rods 123 are provided at the bottom of the connecting plate 122, a connecting ring 124 is provided at the bottom of the first connecting rod 123, a sleeve ring 126 is provided on the explosion suppressor 125, a second movable groove is provided on the ring, a first supporting block 127 is provided in the second movable groove, a first connecting spring 128 is provided on the first supporting block 127, one end of the first connecting spring 128 is fixedly connected to the inner wall of the second movable groove, and a first inclined surface is provided on the top surface of the first supporting block 127; a positioning groove 1241 and a first through groove 1242 corresponding to the first support block 127 are provided on the side wall of the connecting ring 124, and the positioning groove 1241 and the first through groove 1242 are staggered.

[0052] When the explosion suppressor 125 is to be installed on the mounting block 116, the collar 126 on the explosion suppressor 125 is aligned with the connecting ring 124 and the explosion suppressor 125 is pushed upward, causing the collar 126 to slide toward the connecting ring 124. At this point, the first inclined surface of the first support block 127 contacts the sidewall of the connecting ring 124, and the first support block 127 moves into the second movable groove. As the explosion suppressor 125 continues to rise, the first support block 127 slides along the sidewall of the connecting ring 124 and gradually moves to the top of the connecting ring 124. The first support block 127 aligns with the positioning groove 1241 and enters the positioning groove 1241. When the first support block 127 is fully inserted into the positioning groove 1241, the first connecting spring 128 returns to its original state, pushing the first support block 127 out of the second movable groove so that the first support block 127 rests in the positioning groove 1241, thus achieving a quick connection between the explosion suppressor 125 and the mounting block 116. At the same time, due to the provision of positioning groove 1241, even if explosion suppressor 125 is subjected to external forces, first support block 127 cannot be dislodged from positioning groove 1241, thereby ensuring a stable connection between explosion suppressor 125 and mounting block 116. Furthermore, the provision of first connecting rod 123 and connecting ring 124 effectively supports and secures explosion suppressor 125, improving its stability and safety during experiments.

[0058] The two sides of the movable block 107 are symmetrical, that is, the structures on the left and right sides of the movable block 107 are the same. By controlling the movement of the push blocks 133 on both sides of the movable block 107, the loading blocks 106 on any one side or both sides of the movable block 107 can be driven to move together, so as to facilitate the replacement of a single or multiple explosion suppressors 125.

[0059] When replacing the explosion suppressor 125, the new explosion suppressor 125 is placed in the second loading groove 1081 through the second through hole. At this time, the loading plate 105 is at the bottom of the third guide rail 109, and the loading block 106 is at the bottom of the fourth guide rail 110. The loading block 106 and the loading plate 105 are in a lower position to place the explosion suppressor 125; after opening the sealing plate 103, the electric push rod 114 pushes the first guide rail 111 to extend from the opening, and the second electromagnet on the same side as the extended first guide rail 111 is energized to generate a magnetic force. The second electromagnet generates a magnetic force that repels the push block 133 and pushes the push block 133 to move outward. The push block 133 moves to the bottom of the loading block 106. When the push block 133 moves, it drives the first transmission block 134 and the second transmission block 144 to move. The first transmission block 134 rests on the side wall of the loading block 106, and the second transmission block 144 rests on the loading plate 105 side wall, so that the second transmission wheel 139 and the third transmission wheel 140 form a transmission cooperation, and the fourth transmission wheel 145 and the sixth transmission wheel 147 form a transmission cooperation; the hydraulic cylinder 104 drives the movable block 107 to rise, the push block 133 pushes the loading block 106 to rise, and the first protrusion 1352 abuts on the stop block 136 so that the loading block 106 pushes the loading plate 105 to rise. When the loading plate 105 rises to the highest point of the third guide rail 109, the first loading ring 138 abuts on the bottom of the explosion suppressor 125 connected to the first guide rail 111 and pushes the explosion suppressor 125 to move upward relative to the mounting block 116, and the first support block 127 is lifted from the positioning groove 1241. The fourth transmission wheel 145 drives the sixth transmission wheel 147 to rotate, and the first loading ring 138 rotates the explosion suppressor 125 so that the first support block 127 is aligned with the first through groove 1242;When the loading plate 105 moves to the top of the third guide rail 109, the second slider 1051 moves to the top of the second slide groove, and the push plate 130 moves to the second support block 131 to push the second support block 131 to move. At the same time, the second support block 131 pushes the push plate 130 to move when it moves. When the push plate 130 moves to the top of the second support block 131, it abuts against the second protrusion 1091. The second protrusion 1091 pushes the push plate 130 to move. The push plate 130 drives the movable rod to move so that the stopper 136 enters the third movable groove. The second connecting rod 135 directly passes through the first through hole, so that the loading block 106 moves relative to the loading plate 105, the electric push rod 114 drives the first guide rail 111 to move back a short distance, the mounting block 116 moves to above the second through hole, the loading block 106 rises and drives the new explosion suppressor 125 to rise together, the first support block 127 on the collar 126 on the new explosion suppressor 125 is aligned with the positioning groove 1241, the first inclined surface on the first support block 127 abuts against the inner wall of the connecting ring 124 and then moves into the second movable groove until the first support block 127 moves to the top of the positioning groove 1241 and then extends from the second movable groove to abut against the positioning groove 124 1 bottom surface, at this time, the push rod 1062 rises together with the loading block 106 and enters the second chute. When the loading block 106 moves to the bottom of the loading plate 105, the push rod 1062 moves to the side of the second support block 131 and pushes the second support block 131 into the fifth movable groove. Since the length of the push rod 1062 is greater than the length of the extended movable rod, when the movable block 107 descends, the loading plate 105 and the loading block 106 descend together. After the new explosion suppressor 125 is disengaged from the second through hole, the electric push rod 114 drives the first guide rail 111 to move into the box body 101 to complete the explosion suppressor 1 25 Installation; The loading plate 105 drives the replaced explosion suppressor 125 downward. After the second slider 1051 moves to the bottom of the second chute, the loading plate 105 stops moving, the movable block 107 continues to move downward, and the loading block 106 moves downward relative to the loading plate 105. After the protrusion abuts against the side wall of the stopper 136, the action of the third inclined surface pushes the stopper 136 to move, causing the protrusion to move below the stopper 136, completing the reset of the loading block 106 and the loading plate 105. At this time, the loading plate 105 is in a lower position, and the replaced explosion suppressor 125 can be easily removed and recycled.
