[0003] Current distribution boxes lack the ability to cope with high-temperature accidents, while others use sensors and other electrical appliances to prevent and handle fire accidents. These sensors and other electrical appliances require the power supply to be in normal operation. In high-temperature environments, they are prone to failure and may not work properly, resulting in low reliability and an inability to prevent accidents from occurring, spreading, and escalating in a timely manner. Therefore, a comprehensive low-voltage distribution box is proposed. Summary of the Invention
[0004] This invention provides an integrated low-voltage distribution box, which aims to solve the problems of current distribution boxes lacking the ability to cope with high-temperature accidents, and others using sensors and other electrical appliances to prevent and handle fire accidents. However, these sensors and other electrical appliances require the power supply to be in normal operation, and are prone to failure in high-temperature environments, posing a risk of not working properly. This results in low reliability and an inability to prevent the occurrence, spread, and expansion of accidents in a timely manner.
[0005] This invention provides a comprehensive low-voltage distribution box, comprising a distribution box, a support base, a partition wall, and a box shell. An outer wall is installed at one end of the box shell, with several connecting holes pre-drilled at the top of the outer wall. A partition wall is installed at the other end of the box shell, and a sealing cover is installed between the outer wall and the partition wall, the sealing cover being movably connected to the box shell. A second sealing cover is installed on the other side of the box shell, also movably connected to the box shell. The support base is installed on the inner side of the box shell, and several connecting holes are pre-drilled on the support base. A flow passage 1; the bottom wall of the support 1 is fixedly connected to the inner bottom wall of the box shell through a vertical column; a square hole is recessed in the partition wall; a swing hole is reserved at the bottom of the partition wall; a trigger assembly is installed on the inner side of the box shell; the bottom wall of the trigger assembly is higher than the top wall of the support 1; the trigger assembly includes a trigger frame and an intermediate frame 2; the intermediate frame 1 is installed in the middle section of one end of the trigger frame; the middle part of the trigger frame is composed of several grids formed by the trigger frame; metal strips are installed at both ends of the trigger frame; the metal strips are connected to the trigger frame.
[0006] One of the metal strips is equipped with a middle frame 1 in the middle section, and another metal strip is equipped with a middle frame 3 in the middle section. One end of the middle frame 3 is welded with a single claw 3, and one end of the middle frame 1 is welded with a single claw 1. A middle frame 2 is installed on the side wall of the outer wall, and one end of the middle frame 2 is welded with a single claw 2. The single claw 2 and the single claw 1 are connected.
[0007] The intermediate frame three is equipped with a linkage component, the partition wall is equipped with an opening component in the middle, and a gas storage tank assembly is installed at one end of the inner side of the housing. The opening component is located at the lower position of the gas storage tank assembly. If a high-temperature accident occurs in any area of the support seat one, the trigger frame will decompose and melt.
[0008] Furthermore, the linkage assembly includes a locking frame, which is installed on the wall surface of the partition wall facing the outer wall. Two mounting plates are welded to one end of the locking frame, and a rolling roller is screwed between the two mounting plates. The outer circumference of the rolling roller is connected to the outer side of the soft rope. One end of the soft rope is connected to a single claw three, and the tail of the soft rope is connected to a middle strip. The lower end of the middle strip is fixed to a plumb bob. A flow hole two is recessed in the middle section of the soft rope, and a diverter seat is installed on the wall surface of the soft rope facing the partition wall. The diverter seat is a regular triangular prism.
[0009] The diverter can release inert gas from the gas storage tank assembly. After passing through the edges of the regular triangular prism, the inert gas is dispersed to both sides by the diverter until it permeates the area around the support seat, thereby isolating the support seat from the outside gas and making it difficult for the support seat and the device on the support seat to catch fire or continue to spread the fire.
[0010] The swing assembly includes a swing platform, a central column is installed in the middle of the swing platform, a limiting plate is preset at one end of the swing platform, and an impact seat is preset at the other end of the swing platform. The central column is screwed into the inside of the swing hole, and the impact seat is curved.
[0011] By adopting the above scheme, the curved impact seat can increase the contact surface between the end of the impact seat away from the swing table and the opening component, thereby improving the force transmission efficiency.
[0012] Furthermore, the opening assembly includes a limiting support and an elastic element two. An elastic element one is installed on one side of the tail of the limiting support, with one end of the elastic element one abutting against the partition wall. A force-bearing seat is welded to the other side of the tail of the limiting support. A support plate one is installed at the tail of the elastic element two. Two support rods one are installed at one end of the support plate one, distributed on both sides of the limiting support. The end of the support rod one away from the support plate one is bolted to the outer side of the partition wall. The top wall of the elastic element two abuts against the support plate two, and one end of the top wall of the support plate two abuts against the limiting support. A lifting column is installed at the other end of the top wall of the support plate two. A support plate three is welded to the end of the lifting column away from the support plate two. Two support rods two are welded to one end of the support plate three. The heads of the two support rods two are welded to the same closing plate two. The support plate three is located inside the square opening, and the closing plate two matches the square opening.
[0013] One end of the top wall of the second support piece is rounded, and the bottom wall of the upper part of the limiting support is rounded. The rounded corners of the limiting support and the rounded corners of the second support piece correspond to each other.
[0014] By adopting the above solution, the rounded corners of the limiting support and the second support plate correspond to each other, which can reduce the jamming and resistance between the limiting support and the second support plate, allowing the limiting support and the second support plate to detach smoothly, so that the gas storage tank assembly can release inert gas smoothly and isolate external oxygen.
[0015] Furthermore, the gas storage tank assembly includes a storage tank, a plug-in cylinder is installed on the side of the storage tank near the partition wall, a gas inlet is installed on the top wall of the storage tank, a support base is installed on the bottom wall of the storage tank, the bottom surface of the support base is welded to the support rod three, the inner bottom wall of the tank shell is bolted to the support rod three, the plug-in cylinder is plugged into the square hole, the plug-in cylinder corresponds to and is movably connected to the sealing plate two, and the flow hole two and the diverter seat are matched with the plug-in cylinder.
[0016] By adopting the above solutions, some current distribution boxes lack the ability to cope with high-temperature accidents. The rest use electrical appliances, including sensors, to prevent and handle accidents. However, these electrical appliances require the power supply to be in normal operation. In high-temperature environments and during the accident, there is a risk of malfunction and failure to work properly, resulting in low reliability and an inability to prevent the spread and expansion of accidents in a timely manner.
[0017] Furthermore, a ventilation component is installed on the outer wall. The ventilation component includes elastic ropes, a sliding cavity, a second communication hole, and a second passage hole. A sliding cavity is reserved on the inner side of the outer wall. Several second communication holes are recessed in the outer wall. The sliding cavity divides each second communication hole into two sections. A sealing plate is installed on the inner side of the sliding cavity. The number of second and first communication holes is the same. The sealing plate is movably connected to the sliding cavity. Several elastic ropes are installed between the lower end of the sealing plate and the bottom surface of the inner side of the sliding cavity. Several first communication holes are recessed on the sealing plate. The first and second communication holes correspond to each other. A tension rope is connected to the head of the sealing plate. A first passage hole is milled in the outer wall. The tension rope passes through the first passage hole. One end of the tension rope is connected to the second intermediate frame.
[0018] By adopting the above scheme, when the central axes of the first and second communication tunnels coincide, the inside of the box shell is connected to the outside, so that the box shell can exchange gas through the second and first communication tunnels, thereby cooling the inside of the box shell.
[0019] After the triggering component is installed inside the housing, the plumb bob pulls the middle bar and the soft rope under the action of gravity. The middle bar and the soft rope pull the single claw three and the middle frame three. The single claw three and the middle frame three pull the trigger frame. The trigger frame uses the middle frame one and the single claw one to pull the single claw two and the middle frame two. The middle frame two pulls the tension rope. The tension rope pulls the sealing plate one. The sealing plate one is constrained by the elastic rope. The elastic rope is stretched, and the communication hole one and the communication hole two are connected.
[0020] After the trigger frame breaks, the elastic rope releases its elasticity, pulling the sealing plate one down, so that the two sections of the communication hole two are separated by the part of the sealing plate one other than the communication hole one, thus isolating the bottom of the cavity inside the shell from the outside world and preventing inert gas from escaping through the communication hole two.
[0021] Compared with the prior art, the above-mentioned technical solution of the present invention has the following beneficial technical effects:
[0022] 1. In this invention, a triggering component is used. After a high-temperature accident, the high temperature causes the structure of the triggering frame to change and break. The soft rope and the middle strip connected to the plumb bob lose the tension constraint of the triggering frame. Under the action of gravity, the plumb bob accelerates down to one end of the swing platform. The plumb bob exerts pressure on one end of the swing platform, causing one end of the swing platform to swing down. The other end of the swing platform rises up and hits the force seat with the impact seat. The single claw three stops in the gap between the rolling roller and the locking frame. The force seat separates from the head of the limit support and the second support plate with the force seat. The translation of the force seat causes the length of the first elastic element to decrease. The force seat translates with the limit support and separates from the second support plate. The elastic potential energy of the second elastic element is released. The second elastic element squeezes the second support plate and the lifting column to move upward. The second support plate and the lifting column push the third support plate to move upward. The third support plate, with the second sealing plate, leaves from the insertion tube, so that the channel originally sealed by the second sealing plate of the insertion tube is opened and the inert gas is released.
[0023] The inert gas inside the plug-in tube passes through the space between the two support rods and enters the inner side of the box shell. The inert gas settles to the lower layer inside the box shell, covering the support seat and the device on it. The support seat and the device on it are isolated from the outside gas, so that the support seat and the device on it cannot catch fire or continue to spread the fire, thus bringing it under control. This causes the outside gas to be either squeezed out or isolated from the support seat, thereby achieving a rapid response after a high temperature accident. Moreover, it does not use electrical appliances to deal with the accident, does not require the participation of power supply devices, and is a fully mechanical mechanism, which greatly improves its reliability.
[0024] 2. In this invention, the middle part of the trigger frame is composed of several grids formed by the trigger frame. If a high temperature accident occurs in any area of the support seat, the trigger frame will decompose and melt. The trigger frame is highly sensitive and can promptly and efficiently trigger other components to release inert gas to prevent the accident from spreading. The trigger frame contains flame retardant, which prevents the trigger frame from being ignited and prevents the accident from escalating.
[0025] 3. In this invention, the connection between single claw one, single claw two, single claw three and soft rope is very easy. It is also very easy to remove and replace the trigger frame. Then, the trigger frame is used to suspend the plumb bob again, and inert gas is added to the storage box using the air inlet. The sealing plate two is checked and continuously covers the plug-in cylinder, making daily inspection and installation more convenient and efficient.
[0026] 4. In this invention, a diversion seat is used, wherein the diversion seat is a regular triangular prism. After the inert gas released from the gas storage tank assembly passes through the edges of the regular triangular prism, it is dispersed to both sides by the diversion seat, so that the inert gas is wrapped from both sides of the support seat one towards the middle until the inert gas permeates the area around the support seat one, thereby isolating the support seat one from the outside gas, thus preventing the support seat one and the outer shell of the device from burning or continuing to spread the fire.
[0027] 5. In this invention, during the sinking process of the inert gas, other gases are squeezed out from the connecting hole, and the inside of the box shell is filled with inert gas, so that the support seat 1 and the device on the support seat 1 cannot catch fire or continue to expand the fire. The inert gas will not cause corrosion or damage to the device.
[0028] 6. In this invention, by utilizing the corresponding rounded corners of the limiting support and the second support piece, the jamming and resistance between the limiting support and the second support piece can be reduced, allowing the limiting support and the second support piece to detach smoothly, so that the gas storage box assembly can smoothly release inert gas and isolate external oxygen.
[0029] 7. In this invention, the impact seat is curved. During the impact of the impact seat against the force-bearing seat, the curved impact seat can expand the contact surface between the end of the impact seat away from the swing table and the opening component, thereby improving the force transmission efficiency. After the plumb bob reaches the outside of the swing table, it is supported by the swing table. After the swing table swings, the plumb bob can fall from one end. The limiting plate and the impact seat have the same mass, so that the swing table can remain horizontal without the action of external force.
[0030] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

Detailed Implementation
[0043] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.
[0044] like Figure 1As shown in the figure, the present invention proposes an integrated low-voltage distribution box, including a distribution box 12. The distribution box 12 includes a support base 1206, a partition wall 1203, and a box shell 1202. An outer wall 12010 is installed at one end of the box shell 1202, and several connecting holes 12011 are reserved at the head of the outer wall 12010. The partition wall 1203 is installed at the other end of the box shell 1202. A sealing cover 1204 is installed between the outer wall 12010 and the partition wall 1203. The sealing cover 1204 is movably connected to the box shell 1202. A second sealing cover 1205 is installed on the other side of the box shell 1202. The second sealing cover 1205 is movably connected to the box shell 1202. The support base 1206 is installed on the inner side of the box shell 1202. Several flow holes 1208 are reserved on the support 1206. The bottom wall of the support 1206 is fixed to the inner bottom wall of the shell 1202 through the vertical column 1207. A square hole is recessed on the partition wall 1203. A swing hole 1209 is reserved at the lower part of the partition wall 1203. A trigger assembly 13 is installed on the inner side of the shell 1202. The bottom wall of the trigger assembly 13 is higher than the top wall of the support 1206. The trigger assembly 13 includes a trigger frame 1302 and an intermediate frame 1306. An intermediate frame 1303 is installed in the middle section of one end of the trigger frame 1302. The middle part of the trigger frame 1302 is composed of several grids formed by the trigger frame 1302. Metal strips are installed at both ends of the trigger frame 1302. The metal strips are connected to the trigger frame 1302.
[0045] One of the metal strips is fitted with a middle frame 1303 in the middle section, and another metal strip is fitted with a middle frame 3 1307 in the middle section. One end of the middle frame 3 1307 is welded with a single claw 3 1308, and one end of the middle frame 1303 is welded with a single claw 1304. The side wall of the outer wall 12010 is fitted with a middle frame 2 1306, and one end of the middle frame 2 1306 is welded with a single claw 2 1305. The single claw 2 1305 and the single claw 1304 are connected.
[0046] The intermediate frame 1307 is equipped with a linkage component 14, the partition wall 1203 is equipped with an opening component 16 in the middle, and the gas storage tank assembly 17 is installed at one end of the inner side of the housing 1202. The opening component 16 is located at the lower position of the gas storage tank assembly 17. If a high temperature accident occurs in any area of the support 1206, the trigger frame 1302 will decompose and melt.
[0047] The linkage assembly 14 includes a locking frame 1401. The locking frame 1401 is installed on the wall surface of the partition wall 1203 facing the outer wall 12010. Two mounting plates 1403 are welded to one end of the locking frame 1401. A rolling roller 1404 is screwed between the two mounting plates 1403. The outer peripheral surface of the rolling roller 1404 is connected to the outer side of the soft rope 1405. One end of the soft rope 1405 is connected to a single claw 1308. The tail of the soft rope 1405 is connected to a middle strip 1408. The lower end of the middle strip 1408 is fixed to a plumb bob 1409. A flow hole 1406 is recessed in the middle section of the soft rope 1405. A diverter seat 1407 is installed on the wall surface of the soft rope 1405 facing the partition wall 1203. The diverter seat 1407 is a regular triangular prism.
[0048] The diverter seat 1407 can release inert gas from the gas storage tank assembly 17. After passing through the edges of the regular triangular prism, the inert gas is dispersed to both sides by the diverter seat 1407 until it permeates the area around the support seat 1206. This isolates the support seat 1206 from the outside gas, making it difficult for the support seat 1206 and the device on the support seat 1206 to catch fire or for the fire to continue to spread.
[0049] The swing assembly 15 includes a swing platform 1502, a central column 1503 is installed in the middle of the swing platform 1502, a limiting piece 1504 is preset at one end of the swing platform 1502, and an impact seat 1505 is preset at the other end of the swing platform 1502. The central column 1503 is screwed into the inside of the swing hole 1209, and the impact seat 1505 is curved.
[0050] The curved impact seat 1505 can increase the contact surface between the end of the impact seat 1505 away from the swing table 1502 and the opening component 16, thereby improving the force transmission efficiency.
[0051] The opening assembly 16 includes a limiting support 1602 and an elastic element 1607. An elastic element 1603 is mounted on one side of the tail of the limiting support 1602, with one end of the elastic element 1603 abutting against the partition wall 1203. A force-bearing seat 1604 is welded to the other side of the tail of the limiting support 1602. A support plate 1605 is mounted on the tail of the elastic element 1607, with two support rods 1606 mounted on one end of the support plate 1605. The two support rods 1606 are distributed on both sides of the limiting support 1602, with the end of the support rod 1606 furthest from the support plate 1605 and the outer edge of the partition wall 1203... The elastic element 1607 is bolted to the side. The top wall of the elastic element 1607 abuts against the support piece 1608. One end of the top wall of the support piece 1608 abuts against the limiting support 1602. A lifting column 1609 is installed at the other end of the top wall of the support piece 1608. A support piece 16010 is welded to the end of the lifting column 1609 away from the support piece 1608. Two support rods 16011 are welded to one end of the support piece 16010. The heads of the two support rods 16011 are welded to the same closing piece 16012. The support piece 16010 is located inside the square hole. The closing piece 16012 matches the square hole.
[0052] One end of the top wall of the second support piece 1608 is rounded, and the bottom wall of the upper part of the limiting support 1602 is rounded. The rounded corners of the limiting support 1602 and the rounded corners of the second support piece 1608 correspond to each other.
[0053] The rounded corners of the limiting support 1602 correspond to the rounded corners of the second support piece 1608, which can reduce the jamming and resistance between the limiting support 1602 and the second support piece 1608, allowing the limiting support 1602 and the second support piece 1608 to smoothly disengage, so that the gas storage box assembly 17 can smoothly release inert gas and isolate external oxygen.
[0054] The gas storage tank assembly 17 includes a storage tank 1702. A plug-in tube 1703 is installed on the side of the storage tank 1702 near the partition wall 1203. A gas inlet 1704 is installed on the top wall of the storage tank 1702. A support base 1705 is installed on the bottom wall of the storage tank 1702. The bottom surface of the support base 1705 is welded to the support rod 1706. The inner bottom wall of the tank shell 1202 is bolted to the support rod 1706. The plug-in tube 1703 is plugged into the square hole. The plug-in tube 1703 corresponds to and is movably connected to the sealing plate 16012. The flow hole 1406 and the diverter 1407 are matched with the plug-in tube 1703.
[0055] Currently, some distribution boxes lack the ability to cope with high-temperature accidents, while others use electrical appliances, including sensors, to prevent and handle accidents. These electrical appliances require the power supply to be in normal operation. In high-temperature environments and during accidents, there is a risk of malfunction and failure to work properly, resulting in low reliability and an inability to prevent the spread and expansion of accidents in a timely manner.
[0056] A ventilation component is installed on the outer wall 12010. The ventilation component includes an elastic rope 1, a sliding cavity 5, a second communication hole 6, and a second passage hole 9. The sliding cavity 5 is pre-formed on the inner side of the outer wall 12010. Several second communication holes 6 are recessed in the outer wall 12010. The sliding cavity 5 divides each second communication hole 6 into two sections. A sealing plate 2 is installed on the inner side of the sliding cavity 5. The number of second communication holes 6 and first communication holes 3 is the same. The sealing plate 2... 2 is movably connected to the sliding cavity 5. Several elastic ropes 1 are installed between the lower end of the sealing plate 2 and the bottom surface of the inner side of the sliding cavity 5. Several communication holes 3 are recessed on the sealing plate 2. The communication holes 3 and 6 correspond to each other. The head of the sealing plate 2 is connected to the tension rope 4. The outer wall 12010 is milled with a passage hole 7. The tension rope 4 passes through the passage hole 7. One end of the tension rope 4 is connected to the intermediate frame 1306.
[0057] When the central axes of the first communication hole 3 and the second communication hole 6 coincide, the inside of the box shell 1202 is connected to the outside, so that the box shell 1202 can exchange gas through the second communication hole 6 and the first communication hole 3, thereby cooling the inside of the box shell 1202.
[0058] After the trigger assembly 13 is installed inside the housing 1202, the plumb bob 1409 pulls the intermediate bar 1408 and the soft rope 1405 under the action of gravity. The intermediate bar 1408 and the soft rope 1405 pull the single claw three 1308 and the intermediate frame three 1307. The single claw three 1308 and the intermediate frame three 1307 pull the trigger frame 1302. The trigger frame 1302 uses the intermediate frame one 1303 and the single claw one 1304 to pull the single claw two 1305 and the intermediate frame two 1306. The intermediate frame two 1306 pulls the tension rope 4. The tension rope 4 pulls the sealing plate one 2. The sealing plate one 2 is constrained by the elastic rope 1. The elastic rope 1 is stretched, and the communication hole one 3 and the communication hole two 6 are connected.
[0059] After the trigger frame 1302 breaks, the elastic rope 1 releases its elasticity, pulling the sealing plate 12 down, so that the two sections of the communication hole 26 are separated by the part of the sealing plate 12 except for the communication hole 3, thus isolating the bottom of the cavity inside the shell 1202 from the outside world and preventing inert gas from escaping through the communication hole 26.
[0060] The elastic element 1603 includes a tower spring 1, and the elastic element 2 1607 includes a tower spring 2;
[0061] The second sealing piece 16012 can be connected to a switch, and the switch can be controlled to cut off power transmission during movement.
[0062] The trigger frame 1302 is made of PVC and contains flame retardants, including phosphate esters, chlorinated paraffin, antimony trioxide, magnesium hydroxide, and zinc borate.
[0063] The electrical appliance includes a sensor, which is JTY-GD-802;
[0064] The high-temperature accidents mentioned include fires and high temperatures reaching the ignition point of the wire sheath.
[0065] The specific implementation method is as follows: S1: The relevant structure and device of the distribution box are installed on the outside of the support base 1206. The bottom wall of the trigger frame 1302 is higher than the top wall of the support base 1206. The two ends of the trigger assembly 13 are respectively installed on the inside of the box shell 1202 using single claw 1304 and single claw 3 1308. Single claw 1304 and single claw 2 1305 are hooked together, and single claw 3 1308 is hooked together with the soft rope 1405. If a high temperature accident occurs in the distribution box 12, an abnormal high temperature will be generated, and the substances in the box shell 1202 may be ignited.
[0066] Temperatures exceeding 100 degrees Celsius cause the trigger frame 1302 to decompose and melt, which in turn leads to structural changes and breakage of the trigger frame 1302. The forces on the single claw 1305 and the single claw 1304 change, lose balance, and even separate from each other.
[0067] S2: As single claw 2 1305 and single claw 1 1304 separate, or trigger frame 1302 breaks, the soft rope 1405 connected to the plumb bob 1409 on the intermediate bar 1408 and the intermediate bar 1408 lose the tension constraint of the trigger frame 1302. Under the action of gravity, the plumb bob 1409 moves down to one end of the swing platform 1502. The plumb bob 1409 exerts pressure on one end of the swing platform 1502, causing one end of the swing platform 1502 to swing downwards, and the other end of the swing platform 1502... As the rocker arm swings upward, the swing platform 1502, along with the impact seat 1505, impacts the force-bearing seat 1604. The outer wall of the force-bearing seat 1604, away from the limiting support 1602, contacts the end face of the impact seat 1505. The force-bearing seat 1604, along with the head of the limiting support 1602 and the second support plate 1608, separates. The limiting plate 1504 limits the plumb bob 1409, preventing the plumb bob 1409 from separating from the swing platform 1502. The limiting plate 1504 and the impact seat 1505 have the same mass.
[0068] S3: After the force-bearing seat 1604 is impacted, its translation causes the length of the elastic element 1603 to decrease. The force-bearing seat 1604, along with the limiting support 1602, translates and separates from the support plate 1608. The elastic potential energy of the elastic element 1607 is released. The elastic element 1607 compresses the support plate 1608 and the lifting column 1609 upwards. The support plate 1608 and the lifting column 1609 push the support plate 16010 upwards. The support plate 16010, along with the sealing plate 16012, leaves the insertion cylinder 1703, thus reducing the original... The channel sealed by the plug tube 1703 and the sealing plate 16012 is opened. The inert gas in 1791 passes through the space between the two support rods 16011 and enters the inside of the shell 1202. The inert gas settles to the lower layer of the shell 1202, covering the support base 1206 and the device on it. The support base 1206 and the device on it are isolated from the outside gas. The support base 1206 and the device on it lack oxidant and cannot burn or continue to spread the fire, so it is brought under control. The remaining gas is either squeezed out and isolated.
[0069] S4: The lower end of the intermediate strip 1408 is fixedly connected to the lead hammer 1409. The middle section of the soft rope 1405 has a recessed flow hole 1406. The soft rope 1405 is installed with a diverter seat 1407 facing one outer wall of the partition wall 1203. The diverter seat 1407 is a regular triangular prism. The inert gas released by the gas storage tank assembly 17 passes through the outer periphery of the diverter seat 1407. After the inert gas released by the gas storage tank assembly 17 passes through one edge of the regular triangular prism of the diverter seat 1407, it is dispersed to both sides by the diverter seat 1407 until the inert gas permeates the area around the support seat 1206. Thus, the area around the support seat 1206 is wrapped and covered by the inert gas, thereby isolating the combustibles inside from the external oxidizing gas, thereby preventing it from burning or continuing to spread the fire.
[0070] S5: For routine inspection and installation, first open the sealing cover 1204 and sealing cover 2 1205, then lock the height of the plumb bob 1409, separate the single claw 1 1304 and single claw 2 1305, separate the single claw 3 1308 and the soft rope 1405, remove the trigger frame 1302, replace the trigger frame 1302, then use the trigger frame 1302 to suspend the plumb bob 1409 again, and use the air inlet 1704 to add inert gas to the storage box 1702, check and keep the sealing plate 2 16012 continuously covering the plug tube 1703.
