During the movement, the air inside the storage box can be compressed and enter the gas pipe, and finally enter the diverter rack through the gas pipe. When the carbon dioxide gas inside the storage box enters the diverter rack, it will be diverted to the inside of each exhaust pipe, causing the storage ball to rupture and blow the carbon dioxide gas to the inside of the distribution box to control the fire in the electrical component box. Since the interior of the distribution box is relatively sealed, as the carbon dioxide gas continues to enter, it can effectively reduce the oxygen inside the distribution box and the electrical component box, thereby achieving control of the fire in the electrical component box and effectively preventing the spread of the fire.

[0022] 3. By setting up a reaction component, when an open fire occurs inside the electrical component box, that is, when the fuse piece melts and drives the column to move upward, the extrusion plate can be driven to move upward inside the reaction box under the action of the connecting plate and the connecting column 2. During the movement, the material capsule 2 can be squeezed.

When sodium bicarbonate contacts oxygen, it can generate a large amount of carbon dioxide, and the generated carbon dioxide can be discharged into the inside of the distribution box through the through groove, thereby further increasing the carbon dioxide content inside the distribution box, thereby further controlling the fire inside the electrical component box.

[0035] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Figure 1-Figure 10 The present invention provides a technical solution: an electrical component monitoring device for a distribution cabinet, comprising a distribution box 1, a maintenance door 2 is provided on the front surface of the distribution box 1, fire extinguishing components 6 are provided on both sides of the distribution box 1, a protective cover 4 is fixedly installed on the top surface of the distribution box 1, a driving component 10 is provided inside the protective cover 4, an electrical component box 7 and an air switch 8 are fixedly installed inside the distribution box 1, the electrical component box 7 and the air switch 8 are electrically connected, a reaction component 12 is provided on the inner bottom surface of the distribution box 1, a fuse component 13 is provided above the electrical component box 7, and a display instrument 3 is provided on the front surface of the distribution box 1;

[0037] The fuse assembly 13 includes a connection column 1 1305 and a connection column 3 1306, and a fuse piece 1307 is fixedly installed between the connection column 1305 and the connection column 3 1306. The setting of the fuse assembly 13 is used to monitor the inside of the distribution box 1;

[0038] A C-shaped frame 1301 is fixedly installed on the top surface of the distribution box 1, and the C-shaped frame 1301 is located at the traction rope 603, and the traction rope 603 is located inside the C-shaped frame 1301. A clamping groove 1302 is opened inside the C-shaped frame 1301, and a clamping plate 1303 is movably clamped inside the clamping groove 1302. A blade 1304 is fixedly installed on the top surface of the clamping plate 1303, and a column 1309 is fixedly installed on the bottom surface of the clamping plate 1303. One end of the column 1309 extends to the distribution box 1 Inside the electrical box 1, the column 1309 is located on the bottom surface of the distribution box 1 and is fixedly connected to the horizontal plate 1308, the connecting column three 1306 is fixedly installed on the bottom surface of the horizontal plate 1308, the outer surface of the column 1309 is fixedly installed with a fixing ring 1311, and the top surface of the fixing ring 1311 is provided with a spring 2 1312, one end of the spring 2 1312 is fixedly connected to the internal top surface of the distribution box 1, and the other end of the spring 2 1312 is fixedly connected to the top surface of the fixing ring 1311.

[0039] During operation, when an open fire occurs inside the electrical component box 7, the temperature inside the electrical component box 7 will continue to rise. As time goes by, the fire will gradually increase and burst out of the electrical component box 7 to roast the fuse 1307. When the melting temperature of the fuse 1307 is reached, the fuse 1307 will melt. During the melting process, the column 1309 can be driven to move upward on the upper side of the electrical component box 7 under the action of the spring 2 1312, thereby driving the clamping plate 1303 to move upward inside the clamping groove 1302 until the blade 1304 contacts the traction rope 603 and cuts off the traction rope 603. After the traction rope 603 is cut off, the carbon dioxide gas inside the storage box 601 can be released into the inside of the distribution box 1 and discharged toward the electrical component box 7, thereby controlling the fire in the electrical component box 7, thereby achieving the purpose of automatically monitoring the fire source and starting the fire extinguishing equipment to control the fire inside the electrical component box 7, thereby greatly increasing the safety of the overall use of the device.

[0040] The heat-conducting frames 1310 are fixedly installed on both side surfaces of the fuse 1307, and one end of the C-shaped frame 1301 extends to the interior of the electrical component box 7, which can better transmit the temperature to the interior of the fuse 1307, accelerate the fusing of the fuse 1307, and make the fire source monitoring more sensitive.

[0041] The fire extinguishing assembly 6 includes a storage box 601, the number of which is two. The two storage boxes 601 are fixedly mounted on both sides of the distribution box 1, and the interiors of the storage boxes 601 are movably connected with a pull-out plate 602. The fire extinguishing assembly 6 is used to control the fire inside the distribution box 1;

[0042] A traction rope 603 is provided inside the storage box 601, one end of the traction rope 603 is fixedly connected to the bottom surface of the pull-out plate 602, the other end of the traction rope 603 is fixedly connected to the inner bottom surface of the storage box 601, the top surface of the traction rope 603 is fixedly connected to an L-shaped guide wheel frame 604, a diverter rack 606 is fixedly installed on the inner top surface of the distribution box 1, a plurality of exhaust pipes 607 are fixedly connected to the bottom surface of the diverter rack 606, storage balls 608 are fixedly installed on the bottom surfaces of the plurality of exhaust pipes 607, an air supply pipe 611 is fixedly connected between the diverter rack 606 and the storage box 601, a one-way valve 612 is fixedly installed on the outer surface of the air supply pipe 611, a connecting pipe 609 is fixedly connected to the surface of one side of the storage box 601, a valve 610 is fixedly installed on the outer surface of the connecting pipe 609.

[0043] During operation, when the blade 1304 cuts off the traction rope 603, the pull-out plate 602 loses traction inside the storage box 601 and moves downward under the action of the spring 605. During the movement, the air inside the storage box 601 can be compressed and enter the inside of the gas pipe 611, and finally enter the inside of the diverter rack 606 through the gas pipe 611. After the carbon dioxide gas inside the storage box 601 enters the inside of the diverter rack 606, it will be diverted to the inside of each exhaust pipe 607, causing the storage ball 608 to rupture and blow the carbon dioxide gas to the inside of the distribution box 1, thereby controlling the fire in the electrical component box 7. Since the inside of the distribution box 1 is relatively sealed, as the carbon dioxide gas continues to enter, the oxygen inside the distribution box 1 and the electrical component box 7 can be effectively reduced, thereby achieving control of the fire in the electrical component box 7 and effectively preventing the spread of the fire.

[0044] A spacer ring 6071 is fixedly installed inside the exhaust pipe 607, 6072 is arranged on the inner side of the spacer ring 6071, a conical sealing ring 6073 is installed on the outer surface of 6072, a needle 6074 is fixedly installed on the bottom surface of 6072, and a material bag 11 is placed on the top surface of the reaction box 1201, and the interior of the material bag 11 is filled with dry powder.

[0045] During operation, after the carbon dioxide gas enters the interior of each exhaust pipe 607 through the diverter rack 606, the exhaust pipe 607 is sealed by the spacer rings 6071, 6072 and the conical sealing ring 6073 to form a relatively closed space. As the carbon dioxide gas inside the diverter rack 606 continues to enter the interior of the diverter rack 606, the pressure inside the exhaust pipe 607 continues to increase. As the pressure continues to increase, it can compress 6072 and the conical sealing ring 6073 until the conical sealing ring 6073 is compressed and deformed, and then it can be quickly pushed out by the carbon dioxide gas to break the storage ball 608. On the one hand, the carbon dioxide gas entering the diverter rack 606 can smoothly enter the interior of the distribution box 1, and on the other hand, it can break the storage ball 608, causing the storage ball 608 to rupture, and the dry powder on its temporal part will explode and disperse, scattering inside the distribution box 1, and scattering inside the electrical component box 7, thereby realizing the fire extinguishing operation inside the electrical component box 7.

[0046] Furthermore, the ejected 6072 continues to move downward and finally punctures the material capsule 11 located therebelow. When the material capsule 11 is punctured by 6072, the dry powder filled therein can also explode and disperse inside the distribution box 1, thereby further improving the fire extinguishing effect.

[0047] Through the above, when an open fire occurs inside the electrical component box 7, the automatic control blade 1304 can cut off the traction rope 603 to allow the carbon dioxide inside the storage box 601 to enter the distribution box 1 to control the fire inside the electrical component box 7, and at the same time as the carbon dioxide gas enters the distribution box 1, the storage ball 608 and the dry powder inside the material bag 11 can be released for fire extinguishing operations in the electrical component box 7, thereby greatly improving the safety of the entire device during actual use, and achieving the purpose of automatic fire control and automatic fire extinguishing.

[0048] The driving assembly 10 includes a fixing plate 1001, which is fixedly mounted on the top of the distribution box 1, and two vertical plates 1002 are fixedly mounted on both ends of the top surface of the fixing plate 1001. The driving assembly 10 is configured for inhalation of carbon dioxide;

[0049] The interior of the vertical plate 1002 is rotatably installed with a rotating shaft 1003, and a winding roller 1004 is fixedly installed on the outer surface of the rotating shaft 1003. One end of the traction rope 603 is wound around the interior of the winding roller 1004. A motor 1006 is fixedly installed on the top surface of the fixed plate 1001, and a bevel gear 1007 is fixedly connected to the output end of the motor 1006. A bevel gear 1005 is fixedly installed on one end of the rotating shaft 1003, and the bevel gear 1005 and the bevel gear 1007 are meshed with each other. A fixed plate 14 is fixedly installed on the inner bottom surface of the storage box 601, and a fixed plate 14 is fixedly installed on the top surface of the fixed plate 14. There is a touch switch 15, and an alarm light 5 is fixedly installed on the top surface of the protective cover 4. The alarm light 5 is electrically connected to the touch switch 15. When the pull-out plate 602 moves downward inside the distribution box 1, until the bottom surface of the pull-out plate 602 contacts the touch switch 15, the alarm light 5 is controlled to sound an alarm, thereby warning passers-by not to approach easily, further improving the monitoring effect. The touch switch 15 and the alarm light 5 are powered by batteries and do not use the power resources inside the distribution box 1. Therefore, in the process of overall power failure of the distribution box 1, the use of the alarm light 5 is not affected.

[0050] During operation, the motor 1006 is started by controlling the motor 1006. During the process of starting the motor 1006, the bevel gear 1007 can be driven to rotate. During the process of rotating the bevel gear 1007, the two bevel gears 1005 located outside the bevel gear 1007 can be driven to rotate in opposite directions, thereby driving the rotating shaft 1003 to rotate, and then driving the winding roller 1004 to rotate, so as to realize the winding of the traction rope 603 on both sides of the distribution box 1. Before winding, the valve 610 is opened and the connecting pipe 609 is connected to the external conveying pipeline. As the winding roller 1 004 By winding up the traction rope 603, the pull-out plate 602 can be driven to move upward inside the storage box 601. During the upward movement of the pull-out plate 602, a negative pressure is generated inside the storage box 601. Under the action of the negative pressure, the external carbon dioxide gas is sucked into the storage box 601 through the connecting pipe 609 for storage. At this time, the spring 1 605 is in a taut state until the pull-out plate 602 moves to the top of the storage box 601, and the injection of carbon dioxide gas can be completed, thereby achieving the purpose of automatically adding carbon dioxide gas to the storage box 601.

[0051] The reaction assembly 12 includes a reaction box 1201, which is fixedly installed on the inner bottom surface of the distribution box 1. The reaction box 1201 has an extrusion plate 1205 that is movably connected inside. The extrusion plate 1205 divides the reaction box 1201 into a material chamber 1206 and a placement chamber 1207. Sodium bicarbonate is placed inside the material chamber 1206, and a material capsule 1208 is placed inside the placement chamber 1207. The material capsule 1208 is filled with calcium carbonate. A plurality of through holes 1209 are formed through the top surface of the extrusion plate 1205, and a plurality of through grooves 1210 are formed through both sides of the reaction box 1201. A connecting column 1203 is fixedly connected to the top surface of the extrusion plate 1205. One end of the connecting column 1203 extends to the outside of the connecting plate 1202. The connecting plate 1202 is fixedly installed on one end of the connecting column 1203 that extends to the outside of the reaction box 1201. The connecting plate 1202 is fixedly connected to the outer surface of the column 1309.

[0052] During operation, when an open fire occurs inside the electrical component box 7, that is, when the fuse 1307 melts and drives the column 1309 to move upward, the extrusion plate 1205 can be driven to move upward inside the reaction box 1201 under the action of the connecting plate 1202 and the second connecting column 1203, and the material capsule 1208 can be squeezed during the movement. When the bearing pressure of the material capsule 1208 is reached, the material capsule 1208 will burst, and the calcium carbonate stored therein can be scattered on the top surface of the extrusion plate 1205, that is, scattered inside the placement cavity 1207, and finally through the extrusion plate 1205 The multiple through holes 1209 opened on the top surface fall into the interior of the extrusion plate 1205 and come into contact with the sodium bicarbonate inside the extrusion plate 1205, thereby accelerating the reaction speed of the sodium bicarbonate. When sodium bicarbonate comes into contact with oxygen, it can produce a large amount of carbon dioxide. The produced carbon dioxide can be discharged into the interior of the distribution box 1 through the through groove 1210, further increasing the carbon dioxide content inside the distribution box 1, thereby further controlling the fire inside the electrical component box 7. As the temperature inside the distribution box 1 continues to rise, the temperature of the reaction box 1201 will also continue to rise, thereby further accelerating the reaction effect.

[0053] Among them, the sodium bicarbonate can absorb the oxygen inside the distribution box 1 during the reaction process, thereby reducing the oxygen content inside the distribution box 1, thereby greatly improving the fire control effect, and when the material capsule 11 is punctured by the needle 6074, the sodium hydroxide inside the material cavity 1206 can be exposed to oxygen, that is, the material capsule 11 can achieve the sealing effect on the reaction box 1201 before it is broken, preventing oxygen from entering the reaction box 1201 too early, causing the sodium hydroxide inside the material cavity 1206 to react too early, and the broken material capsule 11 can be laid on the top surface of the reaction box 1201, and can burn when encountering an open flame. On the one hand, it can further consume the oxygen content inside the distribution box 1, and on the other hand, it can further heat the reaction box 1201, further improving the reverse effect.

[0054] Specifically, the working process or working principle of the electrical component monitoring device for a distribution cabinet is as follows: when in use, the motor 1006 is controlled to start. During the process of starting the motor 1006, the bevel gear 1007 can be driven to rotate. During the process of rotating the bevel gear 1007, the two bevel gears 1005 located outside the bevel gear 1007 can be driven to rotate in opposite directions, thereby driving the rotating shaft 1003 to rotate, and then driving the winding roller 1004 to rotate, so as to realize the winding of the traction rope 603 on both sides of the distribution box 1. Before winding, the valve 610 is opened, and the connecting pipe 609 is connected to the external conveying pipeline. As the winding roller 1004 winds up the traction rope 603, the pull-out plate 602 can be driven to move upward inside the storage box 601. During the upward movement of the pull-out plate 602, a negative pressure is generated inside the storage box 601. Under the action of the negative pressure, the external carbon dioxide gas is sucked into the storage box 601 through the connecting pipe 609 for storage.

[0055] When an open fire occurs inside the electrical component box 7, the temperature inside the electrical component box 7 will continue to rise. As time goes by, the fire will gradually increase and burst out of the electrical component box 7 to roast the fuse 1307. When the melting temperature of the fuse 1307 is reached, the fuse 1307 will melt. During the melting process, the column 1309 can be driven to move upward on the upper side of the electrical component box 7 under the action of the spring 2 1312, thereby driving the clamping plate 1303 to move upward inside the clamping groove 1302 until the blade 1304 contacts the traction rope 603 and cuts off the traction rope 603. When the traction rope 603 is cut off, the pull-out plate 602 loses traction inside the storage box 601, and the pull-out plate 602 will be detached from the storage box 601 under the action of the spring 1312. 605 moves downward, and in the process of movement, the air inside the storage box 601 can be compressed and enter the inside of the gas pipe 611, and finally enter the inside of the diversion rack 606 through the gas pipe 611. After the carbon dioxide gas inside the storage box 601 enters the inside of the diversion rack 606, it will be diverted to the inside of each exhaust pipe 607, so that the storage ball 608 ruptures, and the carbon dioxide gas is blown to the inside of the distribution box 1 to control the fire in the electrical component box 7. Since the inside of the distribution box 1 is relatively sealed, with the continuous entry of carbon dioxide gas, the oxygen inside the distribution box 1 and the electrical component box 7 can be effectively reduced, thereby achieving control of the fire in the electrical component box 7 and effectively preventing the spread of the fire.

[0056] When the carbon dioxide gas enters the interior of each exhaust pipe 607 through the diverter rack 606, the exhaust pipe 607 is sealed by the spacer rings 6071, 6072 and the conical sealing ring 6073 to form a relatively closed space. As the carbon dioxide gas in the diverter rack 606 continues to enter the interior of the diverter rack 606, the pressure in the exhaust pipe 607 continues to increase. As the pressure continues to increase, it can compress 6072 and the conical sealing ring 6073 until the conical sealing ring 6073 is compressed and deformed, and then it can be quickly pushed out by the carbon dioxide gas to break the storage ball 608. On the one hand, the carbon dioxide gas entering the diverter rack 606 can smoothly enter the interior of the distribution box 1, and on the other hand, it can break the storage ball 608, causing the storage ball 608 to rupture, and the dry powder on its temporal part will explode and disperse, scattering inside the distribution box 1, and scattering into the interior of the electrical component box 7, thereby realizing the fire extinguishing operation inside the electrical component box 7. When an open fire occurs inside the electrical component box 7, it can also That is, when the fuse piece 1307 melts and drives the column 1309 to move upward, the extrusion plate 1205 can be driven to move upward inside the reaction box 1201 under the action of the connecting plate 1202 and the connecting column 1203. During the movement, the material capsule 1208 can be squeezed. When the bearing pressure of the material capsule 1208 is reached, the material capsule 1208 will burst, and the calcium carbonate stored therein can be scattered on the top surface of the extrusion plate 1205, that is, scattered inside the placement cavity 1207, and finally fall into the extrusion plate 1205 through the multiple through holes 1209 opened on the top surface of the extrusion plate 1205, and contact with the sodium bicarbonate inside the extrusion plate 1205, thereby accelerating the reaction speed of the sodium bicarbonate. When sodium bicarbonate contacts oxygen, it can generate a large amount of carbon dioxide. The generated carbon dioxide can be discharged into the inside of the distribution box 1 through the through groove 1210, further increasing the carbon dioxide content inside the distribution box 1, thereby further controlling the fire inside the electrical component box 7.
