Description

Technical Field

[0001] The invention relates to the technical field of battery protection, and in particular to a UPS battery pack with fire protection function. Background Art

[0002] UPS battery pack, or uninterruptible power supply, is designed to provide continuous and stable power supply to key equipment when the mains power is interrupted or abnormal. It is usually composed of multiple battery cells connected in series and parallel.

[0003] During the use of UPS battery packs, the batteries inside the UPS battery pack are in a powered state for a long time and are prone to aging and damage, and the aging speed of different batteries is uneven. When a single battery short-circuits and spontaneously combusts, the spontaneously combusted battery can easily spread to other intact batteries, causing the entire UPS battery pack to spontaneously combust or even explode. In addition, UPS battery packs are stored in multiple arrangements in the same area. Since the batteries are connected in series or in parallel through wires, when a battery short-circuit causes the entire power outage and the main switch is manually closed, the user cannot quickly separate the spontaneously combusting battery from the intact battery, which can easily cause more serious accidents. Summary of the invention

[0004] In order to overcome the disadvantages that when a single battery short-circuits and spontaneously combusts, the spontaneously combusting battery is likely to affect other intact batteries, and the user cannot quickly separate the spontaneously combusting battery from the intact batteries, which may easily cause more serious accidents, the present invention provides a UPS battery pack with a fireproof function.

[0005] The technical implementation scheme of the present invention is: a UPS battery pack with fireproof function, including a shell, a placement rack and a cooling fan; an opening is opened on the front side of the shell; a placement rack is slidably connected in the shell; a plurality of partitions are arranged on the placement rack; a cooling fan is arranged on the shell; it also includes a wiring board, a limit block, a first elastic member and a trigger assembly; an isolation chamber is arranged at the bottom of the shell, and fire extinguishing dry powder is placed in the isolation chamber; a wiring board is connected to the front side of the placement rack; two limit blocks are slidably connected to the front side of the placement rack; a first groove is respectively opened on the left side and the right side of the shell, and the two limit blocks are respectively located in the corresponding first grooves; a plurality of first elastic members are fixedly connected between the shell and the placement rack; a trigger assembly for triggering the placement rack to move forward is connected in the shell.

[0006] Furthermore, the trigger assembly includes an electromagnet and a push block; the partition is set to be a heat-conducting metal material; a number of push blocks are connected to the shell, the push blocks are made of iron, and all the push blocks are distributed on the left and right sides of the corresponding partition; an electromagnet is slidably arranged in each partition, and both ends of the electromagnet are in contact with the corresponding push block, and each partition is provided with a slide groove for the power supply magnet to move back and forth; a temperature sensor is arranged in each partition, and the temperature sensor is connected to the control component that controls the power supply of the electromagnet through an electrical signal.

[0007] Furthermore, it also includes a connecting block and a first isolation plate; the connecting block is fixedly connected to the rear side of the shell; the connecting block is located at the upper part of the isolation chamber; the connecting block is connected to the first isolation plate for isolating the battery.

[0008] Furthermore, it also includes a card block; a card slot is opened on the rear side of the shell, and the card block is clamped in the card slot; a first limiting portion is arranged on the card block; and a second limiting portion is arranged on the card block.

[0009] Furthermore, it also includes a sliding block, a second elastic member and a second isolation plate; the sliding block is slidably connected to the lower rear side of the first isolation plate; a second groove is opened on the rear side of the shell, and the second groove is located on the upper side of the connecting block; a number of second elastic members are fixedly connected between the sliding block and the first isolation plate; and the second isolation plate is fixedly connected to the front side of the shell.

[0010] Furthermore, a heat insulation board is fixedly connected to the lower side of each partition.

[0011] Furthermore, it also includes a compressed gas bag; a switchable door is respectively arranged on the left and right sides of the shell, and a compressed gas bag is fixedly connected to each door, and the compressed gas bag contains flame retardant gas; a plurality of spikes are respectively arranged on the left and right sides of the placement rack.

[0012] Furthermore, the first isolation plate and the second isolation plate are both made of fire-retardant material.

[0013] Furthermore, it also includes fan-shaped air bags; a plurality of fan-shaped air bags are fixedly connected between the first isolation plate and the shell, and the fan-shaped air bags contain fire extinguishing dry powder; each fan-shaped air bag is provided with a dry powder nozzle at the lower part of one side facing the isolation chamber.

[0014] Furthermore, the dry powder spray nozzle is oriented toward the front and downward.

[0015] The present invention has the following advantages: when a battery becomes abnormally heated, the temperature sensor stops supplying power to the electromagnet through an electrical signal, and the electromagnet stops fixing the push block. The released push block is flipped to push the limit block away from the first groove, and the placement rack and the terminal board are pushed forward by the first elastic member. The abnormal battery is limited by the push block flipped into a horizontal state, so that it cannot move forward with the placement rack, so that the terminal of the abnormally heated battery is disconnected from the terminal board without manual work, and the disconnection is rapid, thereby avoiding excessive damage, and the intact battery can move forward with the placement rack. When the first elastic member pushes the placement rack away from the shell, the abnormal battery loses the support of the partition and falls downward into the isolation chamber, and the abnormal battery is extinguished and cooled by the fire extinguishing dry powder in the isolation chamber, thereby separating the abnormal battery from the intact battery, and avoiding the abnormal battery from spontaneous combustion and affecting the intact battery. When the battery falls into the isolation chamber, the shell body vibrates greatly, and the card block shakes in the card slot of the shell body, and the first limit part is disengaged from the card slot, and the card block is disengaged from the restriction of the first isolation plate. The first isolation plate flips downward to abut against the second isolation plate, and the isolation chamber is closed by the cooperation of the first isolation plate and the second isolation plate. After the abnormal battery enters the isolation chamber, the isolation chamber is closed in time, thereby effectively reducing the amount of fire extinguishing dry powder raised by the battery, and blocking oxygen from entering the isolation chamber, further preventing the abnormal battery from continuing to burn; In the process of the first elastic member pushing the placement rack forward, the compressed gas bag is punctured and cut open by the spikes on both sides of the placement rack, and then the flame-retardant gas in the compressed gas bag is quickly released, so that the shell is quickly filled with the flame-retardant gas, cooling the abnormal battery and isolating the oxygen, thereby effectively preventing the fire from spreading and damaging the intact battery, and effectively preventing the battery from spontaneously combusting and damaging the intact battery before the first isolation plate is flipped down to seal the isolation chamber.

[0019] Example 1 A UPS battery pack with fire protection function, such as Figure 1-Figure 10 As shown, it includes a shell 1, a placement rack 2 and a cooling fan 9; an opening 1001 is opened on the front side of the shell 1; the placement rack 2 is slidably connected in the shell 1; six partitions 2001 are arranged on the placement rack 2, and a battery 8 is placed between each two adjacent partitions 2001; the cooling fan 9 is arranged on the shell 1; It also includes a terminal board 3, a limit block 4, a first elastic member 5 and a trigger assembly; an isolation chamber 1003 is provided at the bottom of the shell 1, and fire extinguishing dry powder is placed in the isolation chamber 1003; a terminal board 3 is detachably plugged into the front side of the placement rack 2, and the output end of the terminal board 3 is electrically connected to the equipment to be powered; two limit blocks 4 that can be moved left and right are slidably connected to the front side of the placement rack 2; a first groove 1002 is respectively provided on the left and right sides of the shell 1, and the two limit blocks 4 are respectively located in the corresponding first grooves 1002; four first elastic members 5 are fixedly connected between the shell 1 and the placement rack 2, and the first elastic members 5 are springs; the first elastic members 5 are initially in a compressed state; a trigger assembly is connected inside the shell 1.

[0020] The trigger assembly includes an electromagnet 101 and a push block 102; the partition 2001 is set to be made of heat-conducting metal material; twelve push blocks 102 are rotatably connected in the shell 1 through a torsion spring, and the push blocks 102 are made of iron. All push blocks 102 are distributed on the left and right sides of the corresponding partition 2001; an electromagnet 101 is slidably set in each partition 2001, and both ends of the electromagnet 101 are in contact with the corresponding push block 102, and each partition 2001 is provided with a slide groove for the power supply magnet 101 to move back and forth; a temperature sensor is set in each partition 2001, and the temperature sensor is connected to the control component that controls the power supply of the electromagnet 101 through an electrical signal; the torsion spring on the push block 102 is initially in a twisted state, and the lower part of the push block 102 is fixed by the corresponding electromagnet 101, so that the push block 102 initially maintains a vertical state.

[0021] It also includes a connecting block 201 and a first isolation plate 6; the connecting block 201 is fixedly connected to the rear side of the shell 1; the connecting block 201 is located at the upper part of the isolation chamber 1003; the connecting block 201 is rotatably connected to the first isolation plate 6 through a torsion spring.

[0022] It also includes a clamping block 7; the torsion spring on the first isolation plate 6 is initially in a twisted state; a clamping slot is opened on the rear side of the inner part of the shell 1, and the clamping block 7 is clamped in the clamping slot; a first limiting portion 7001 is provided on the clamping block 7, and when no external force is applied, the clamping block 7 is fixed in the clamping slot by the first limiting portion 7001; a second limiting portion 7002 is provided on the clamping block 7, and the first isolation plate 6 is limited by the second limiting portion 7002 so that it cannot flip downward.

[0023] It also includes a sliding block 202, a second elastic member 203 and a second isolation plate 204; the sliding block 202 is slidably connected to the lower rear side of the first isolation plate 6; a second groove 1004 is opened on the rear side of the shell 1, and the second groove 1004 is located on the upper side of the connecting block 201; three second elastic members 203 are fixedly connected between the sliding block 202 and the first isolation plate 6, and the second elastic members 203 are springs; the second elastic members 203 are initially in a compressed state; the second isolation plate 204 is fixedly connected to the front side of the shell 1.

[0024] A heat insulation board 2002 is fixedly connected to the lower side of each partition 2001.

[0025] It also includes a compressed gas bag 301; a switchable door is provided on the left and right sides of the shell 1, and each door is detachably connected to a compressed gas bag 301, which contains flame-retardant gas; a plurality of spikes are provided on the left and right sides of the placement rack 2.

[0026] The first isolation plate 6 and the second isolation plate 204 are both made of fire-resistant and flame-retardant materials.

[0027] During operation, the initial placement rack 2 is located outside the shell 1. The user first removes the terminal board 3 from the placement rack 2, places all the batteries 8 on the partition 2001 respectively, and makes the terminal of the battery 8 face forward, and then installs the terminal board 3 on the placement rack 2, so that the terminal of the battery 8 is connected to the terminal board 3. At this time, the terminal of the battery 8 and the terminal board 3 are in a plug-in state, so that all the batteries 8 are connected in series, and the battery 8 is connected to the power supply device through the terminal board 3, providing a continuous and stable power supply for the power supply device, and then pushes the placement rack 2 backward into the shell 1, and pushes the limit block 4 into the first groove 1002. At this time, the first elastic member 5 is compressed, and the limit block 4 is limited by the inner wall of the first groove 1002, and then the placement rack 2 is limited, so that the placement rack 2 is stably stored in the shell 1.

[0028] Since the UPS battery 8 group needs to be powered continuously during use, the battery 8 is prone to aging and damage. When the battery 8 spontaneously ignites during use, it is easy to affect other adjacent intact batteries 8, causing the intact batteries 8 to be damaged by high temperature or flames, and even causing a chain reaction of spontaneous combustion of all the batteries 8 in the housing 1. In addition, since the batteries 8 are connected in series through wires, the user cannot quickly separate the spontaneously ignited battery 8 from the intact battery 8. In the present invention, when the battery 8 generates heat during use, the heat on the battery 8 and the heat conducted to the partition 2001 by the battery 8 are dissipated in time through the cooling fan 9. When a battery 8 generates abnormal heat and the heat exceeds the normal range, it is a sign of impending spontaneous combustion. At this time, the temperature of the partition 2001 below the abnormal battery 8 rises sharply, and the cooling fan 9 cannot dissipate the heat of the partition 2001 in time. At this time, the temperature detected by the temperature sensor rises rapidly, and the temperature sensor uses an electrical signal to make the control component that controls the power supply of the electromagnet 101 stop supplying power to the electromagnet 101, and the electromagnet 101 stops fixing the push block 102, and then as shown in FIG. Figure 8As shown, the torsion spring on the push block 102 drives the push block 102 to flip toward the abnormally heated battery 8, so that the push block 102 is flipped from the vertical state to the horizontal state, and then the push block 102 pushes the limit block 4 away from the first groove 1002, and the limit block 4 slides on all the partitions 2001 and the heat insulation board 2002, so that the placement rack 2 loses its limit. At this time, the elastic force released by the first elastic member 5 pushes the placement rack 2 and the terminal board 3 to move forward, thereby driving the battery 8 to move forward, but the abnormally heated battery 8 is limited by the push block 102 flipped to the horizontal state, so that it cannot move forward with the placement rack 2, so that when the placement rack 2 and the terminal board 3 move forward, the abnormal The connection terminal of the heating battery 8 is disconnected from the terminal board 3 without manual work, and the disconnection is rapid to avoid excessive damage, while the electromagnet 101 on the lower side of the other intact batteries 8 slides backward in the slide groove of the partition 2001 relative to the partition 2001, that is, the limit block 4 on the front side of the intact battery 8 is still fixed by the electromagnet 101 and does not flip over, so that the intact battery 8 can move forward with the placement rack 2, and the heat insulation board 2002 made of heat insulation material is used to prevent the abnormal battery 8 from conducting heat to the temperature sensor in the partition 2001 above it when it is abnormally hot, causing the temperature sensor above it to be triggered, causing the other push blocks 102 to flip over, and then as Fig. 9 As shown, after the first elastic member 5 pushes the placement rack 2 away from the shell 1, the abnormally heated battery 8 loses the support of the partition 2001 and falls downward into the isolation chamber 1003. The abnormal battery 8 is extinguished and cooled by the fire extinguishing dry powder in the isolation chamber 1003, and the abnormal battery 8 is separated from the intact battery 8, thereby effectively preventing the burning of the abnormal battery 8 from affecting the intact battery 8.

[0029] Furthermore, in order to enhance the isolation effect of the abnormal battery 8 and prevent the abnormal battery 8 from vibrating the fire extinguishing dry powder when entering the isolation chamber 1003, causing the fire extinguishing dry powder to fly everywhere, in the initial state, the first isolation plate 6 is fixed by the second limiting portion 7002 of the card block 7 so that it cannot flip downward. Since the abnormal battery 8 has a certain weight, when the battery 8 falls into the isolation chamber 1003, the shell 1 vibrates greatly, and then the card block 7 shakes in the card slot of the shell 1, and the first limiting portion 7001 is disengaged from the card slot, so that the card block 7 is freed from the restriction on the first isolation plate 6, so as to Fig.10As shown, the torsion spring on the first isolation plate 6 releases its elastic force, and the torsion spring on the first isolation plate 6 drives the first isolation plate 6 to flip downward until the first isolation plate 6 abuts against the second isolation plate 204, thereby cooperating with the first isolation plate 6 and the second isolation plate 204 to close the isolation chamber 1003. After the abnormal battery 8 enters the isolation chamber 1003, the isolation chamber 1003 is closed in time, thereby effectively reducing the amount of fire extinguishing dry powder lifted by the battery 8, and blocking oxygen from entering the isolation chamber 1003, further preventing the abnormal battery 8 from continuing to burn. It should be noted that when the present invention is working normally, the card block 7 is abutted and fixed by the placement rack 2, thereby avoiding the card block 7 from being separated from the card slot when the present invention is moved, that is, when the placement position of the present invention is transferred, causing the first isolation plate 6 to be accidentally triggered and flipped downward.

[0030] Since the abnormal battery 8 may explode, the explosion of the abnormal battery 8 will generate a certain impact force. In order to prevent the first isolation plate 6 from being lifted up when the battery 8 explodes, in the initial state, the sliding block 202 is limited by the connecting block 201 to prevent the second elastic member 203 from pushing the sliding block 202 to move downward. When the first isolation plate 6 is flipped downward to fit with the second isolation plate 204, the sliding block 202 loses the limit of the connecting block 201. Fig.10 As shown, the sliding block 202 is pushed backward by the second elastic member 203, so that the sliding block 202 enters the second groove 1004, thereby limiting the sliding block 202 through the inner wall of the second groove 1004, and then limiting the first isolation plate 6, to prevent the first isolation plate 6 from being pushed upward, resulting in the leakage of heat and flames generated by the spontaneous combustion of the fire extinguishing dry powder and the abnormal battery 8, thereby effectively ensuring the fire prevention effect of the present invention.

[0031] Furthermore, in order to prevent the battery 8 from spontaneously combusting rapidly after abnormal heating occurs, causing the abnormal battery 8 to spontaneously combust before the first isolation plate 6 is flipped downward to close the isolation chamber 1003, thereby damaging the intact battery 8, during the process of the first elastic member 5 pushing the placement rack 2 forward, the compressed gas bag 301 is punctured and cut open by the spikes on both sides of the placement rack 2, and then the flame-retardant gas in the compressed gas bag 301 is rapidly released, so that the shell 1 is rapidly filled with the flame-retardant gas, the abnormal battery 8 is cooled and the oxygen is isolated, thereby effectively preventing the battery 8 from spontaneously combusting rapidly after abnormal heating occurs, causing the fire to spread and causing damage to the intact battery 8. It should be noted that the door on the shell 1 can be opened, the used compressed gas bag 301 can be replaced, and the abnormal battery 8 can be taken out so that the present invention can be used again.

[0032] Example 2 On the basis of Example 1, Figure 9-11As shown, it also includes a fan-shaped air bag 401; two left-right symmetrical fan-shaped air bags 401 are fixedly connected between the first isolation plate 6 and the shell 1, and the fan-shaped air bags 401 contain fire extinguishing dry powder; each fan-shaped air bag 401 is provided with a dry powder nozzle 40101 on the lower part of one side facing the isolation chamber 1003.

[0033] The direction of the dry powder spray nozzle 40101 is toward the front and downward.

[0034] Since the fire extinguishing dry powder in the isolation chamber 1003 is located at the bottom of the isolation chamber 1003 and the isolation chamber 1003 is relatively narrow, when the abnormal battery 8 enters the isolation chamber 1003, the movement range of the fire extinguishing dry powder is limited, resulting in less fire extinguishing dry powder moving to the upper part of the abnormal battery 8. In order to further ensure the fire extinguishing and cooling effect of the fire extinguishing dry powder on the abnormal battery 8, during the downward flipping of the first isolation plate 6, as shown in FIG. Fig.10 As shown, the fan-shaped airbag 401 is compressed by cooperating with the first isolation plate 6 and the shell 1, so that the fire extinguishing dry powder in the fan-shaped airbag 401 is sprayed downward from the dry powder nozzle 40101, and then the fire extinguishing dry powder is evenly sprayed on the upper part of the abnormal battery 8, so that the fire extinguishing dry powder completely covers the abnormal battery 8, effectively ensuring the fire extinguishing and cooling effect of the fire extinguishing dry powder on the abnormal battery 8.
