Description

Technical Field

[0001] The present application relates to the field of electrical automation technology, and in particular to an automated intelligent flame-retardant power distribution cabinet with an alarm function. Background Art

[0002] The distribution cabinet, also known as the distribution box, is an important equipment in the power system. It is mainly used in the power system's power generation, transmission, distribution, power conversion and consumption to connect, disconnect, control or protect circuits. During use, electrical components in the distribution cabinet often spontaneously combust due to short circuits, leakage and overload. For this reason, most manufacturers now add automatic flame retardant alarm devices to the distribution cabinet.

[0003] Some of the existing flame-retardant distribution cabinets use flame-retardant materials to make the outer shell of the distribution cabinet and seal the entire distribution cabinet. When a fire occurs in the distribution cabinet, the outer shell made of flame-retardant materials can slow down the spread of the flame, and the internal oxygen can also play a role in extinguishing the fire after it is exhausted. However, this flame-retardant method will lead to poor ventilation of the distribution cabinet, rapid accumulation of internal heat, and before the internal oxygen is exhausted, the flame will affect all electrical components in the entire distribution cabinet, causing all electrical components to be damaged by high temperature. Although the flame-retardant distribution cabinet has certain fireproof performance, in extreme cases, the internal pressure of the distribution cabinet rises sharply. When the internal pressure of the distribution cabinet reaches a certain level, if the sealing performance of the distribution cabinet cannot withstand this pressure, an explosion may occur. Summary of the invention

[0004] The present application proposes an automated intelligent flame-retardant power distribution cabinet with an alarm function, which has the advantages of a fireproof outer cover falling to enclose a space when a fire occurs, a weighted ring driving a thimble to fall and pierce a liquid capsule to squeeze out dilute hydrochloric acid, a marble ring plate falling and hitting a crushing knife to crush it and then reacting with dilute hydrochloric acid to quickly produce carbon dioxide for fire extinguishing, carbon dioxide squeezing gas to move upward through an exhaust whistle to sound an alarm, and a hydraulic hose quickly unfolding to accelerate the falling speed of the fireproof outer cover, so as to solve the problem that the existing flame-retardant power distribution cabinet has poor flame-retardant effect and cannot effectively extinguish fires.

[0005] To achieve the above-mentioned purpose, the present application adopts the following technical scheme: an automated intelligent flame-retardant power distribution cabinet with an alarm function, comprising a base, a power distribution cabinet on the base, and a mounting plate on the top of the base for mounting electronic components, wherein an intelligent flame-retardant device is arranged on the top of the power distribution cabinet; the intelligent flame-retardant device comprises an isolation cover device for providing a flame-retardant space, a sensing device for sensing a fire source, a cutting device for activating the isolation cover device, and a fire extinguishing device for generating carbon dioxide; the isolation cover device comprises a fireproof outer cover arranged at the bottom end of a top cover seat, a skeleton arranged evenly on the fireproof outer cover to maintain the outer shape, and a skeleton arranged on the fireproof outer cover. A weighting ring at the bottom end of the cover and four pull ropes arranged on the inner side of the weighting ring for tightening the fireproof outer cover; a sensing device, including a hydraulic box arranged at the bottom end of the tool seat, positioning cylinders evenly arranged and connected at the bottom end of the hydraulic box, a piston column arranged in the positioning cylinder for squeezing hydraulic oil, a spring arranged on the outside of the piston column for providing power, an induction rope arranged at the bottom end of the piston column for sensing the fire source, and a limit plate arranged at the bottom end of the induction rope for tightening the induction rope; a cutting device, including a tool seat arranged below the top cover seat, a movable groove opened in the tool seat, and a tool column arranged in the movable groove for cutting the pull rope.

[0006] Preferably, a center hole is provided at the center of the top cover seat, and four threading holes are provided in the top cover seat. The top ends of the four pull ropes are movably passed through the threading holes to the center hole and connected to each other, so as to gather the fireproof outer cover and contact the knife column.

[0007] Preferably, the tool seat is located below the center hole, the top end of the tool column is inserted into the center hole, the top end of the tool column is provided with an annular cutting edge, the cutting edge is located below the pull rope in the center hole, a scissors ring is provided at the top end of the center hole, an inclined edge is provided on the outer side of the bottom end of the scissors ring opposite to the cutting edge of the tool column, the scissors ring is located above the pull rope in the center hole, and is used to cooperate with the raised tool column cutting edge to cut the pull rope.

[0008] Preferably, there is a spacing between the top end of the tool seat and the bottom end of the top cover seat, the top center of the tool column is grooved, and the top of the tool column is provided with exhaust holes evenly distributed around the circumference for inputting the upwelling gas into the center hole through the exhaust holes, and an exhaust whistle is provided at the top opening of the center hole for inputting the gas in the center hole into the exhaust whistle to sound an alarm.

[0009] Preferably, the inner cavity of the hydraulic box is connected to the bottom of the movable groove through a hose, so as to introduce hydraulic oil into the movable groove to push the knife column upward.

[0010] Preferably, evenly distributed L-shaped buckling bodies are provided on the top of the base, and the limiting plate is inserted into the gap between the L-shaped buckling body and the top of the base to control the position of the limiting plate. The induction rope is close to the mounting plate and is used to burn and break close to the fire source.

[0011] Preferably, a surrounding recessed groove is provided at the top of the base, and the recessed groove is located directly below the weighted ring, which is used for falling and squeezing the liquid capsule, the liquid capsule is filled with dilute hydrochloric acid, the liquid capsule is movably sleeved in the recessed groove, and evenly distributed ejector pins are provided on the inner side of the bottom end of the weighted ring, which are used for puncturing the liquid capsule and drawing out the liquid.

[0012] Preferably, a marble ring plate is provided at the bottom of the inner wall of the weighted ring, and evenly distributed crushing knives are provided on the inner side of the top opening of the recessed groove. The crushing knives are located directly below the marble ring plate and are used to crush the marble ring plate to increase the reaction area with dilute hydrochloric acid.

[0013] Preferably, evenly distributed hydraulic hoses are provided on the outer side of the fireproof outer cover, and the hydraulic hoses are connected to the inner cavity of the hydraulic box to accelerate the falling speed of the fireproof outer cover.

[0014] The present application provides an automated intelligent flame-retardant power distribution cabinet with an alarm function. When an electronic component catches fire, the nearby induction rope will be ignited, causing the induction rope to be disconnected. At this time, the piston column connected to the induction rope loses its downward limiting force and is lifted up by the drive of the spring, squeezing the hydraulic oil in the positioning cylinder into the hydraulic box and into the bottom of the movable groove, pushing the knife column up, so that the circular blade at the top of the knife column cuts the upper pull rope joint, and cooperates with the scissor ring to cut the pull rope, so that the fireproof cover loses its upward limiting force and falls, closing the entire mounting plate, reducing the entry of air, thereby reducing the continuous oxygen supply to the fire source, delaying or even extinguishing the flame.

[0015] At the same time, when the fireproof cover falls and unfolds, the ejector pin at the bottom of the weighted ring will pierce the liquid bag below, so that the dilute acid salt in the liquid bag will be discharged. At the same time, the marble ring plate will hit the crushing knife below. After crushing, it will come into contact with the dilute hydrochloric acid, and quickly produce a large amount of carbon dioxide. The carbon dioxide occupies a large amount of space in the fireproof cover, displacing the internal air to quickly extinguish the fire. Most of the gas is squeezed upward and will pass through the exhaust whistle to emit a shrill whistle to alarm.

[0016] At the same time, when the induction rope breaks and the piston column is lifted, a part of the hydraulic oil is input into the movable groove to push the knife column up, and the scissor ring will limit the lifting distance of the knife column. At this time, the excess hydraulic oil will be pressed into the hydraulic hose to push the fireproof cover to quickly unfold downward, so as to avoid the problem of the fireproof cover failing to unfold due to stacking, and the rapid unfolding is helpful to quickly close the mounting plate and quickly form a relatively closed space. In this process, the falling speed of the weighted ring and the marble ring plate will be accelerated, so that the impact force of the ejector pin impacting the liquid bag and the marble ring plate impacting the crushing knife will be increased, thereby making the marble ring plate more broken, and the diffusion rate of the dilute hydrochloric acid will be greater, further improving the output rate of carbon dioxide and improving the fire extinguishing speed.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0021] Embodiment 1 See also Figures 1 to 3An automated intelligent flame-retardant power distribution cabinet with an alarm function comprises a base 1, a power distribution cabinet 2 is welded on the outer side of the top of the base 1, and evenly distributed air holes are opened on the outer wall of the power distribution cabinet 2, so that the hot air in the power distribution cabinet 2 can be exchanged with the cold air from the outside through the air holes, thereby cooling the inside of the power distribution cabinet 2, a mounting plate 3 is bolted to the top of the base 1, and electrical components are mounted on the mounting plate 3, a mounting hole is opened on the top of the power distribution cabinet 2, and a top cover seat 4 is bolted to the mounting hole, and the top cover seat 4 seals the mounting hole to prevent rainwater and dust from the outside from pouring into the power distribution cabinet 2 through the mounting hole, causing damage to the internal electronic components.

[0022] See also Figure 2 , Figures 4 to 6 The four sides of the bottom end of the top cover seat 4 are fixedly connected with a fireproof outer cover 5. The material of the fireproof outer cover 5 is airtight or low-permeability fireproof cloth, so that after the fireproof outer cover 5 falls to surround the entire mounting plate 3, it can isolate or reduce the continuous entry of outside air, and when a large amount of carbon dioxide and combustion smoke are produced subsequently, the air pressure in the fireproof outer cover 5 increases. If the fireproof outer cover 5 is made of a material with low air permeability, then part of the smoke and carbon dioxide in the fireproof outer cover 5 will diffuse outward through the fireproof outer cover 5, further hindering the fresh air from entering the interior through the fireproof outer cover 5, thereby isolating the fire source from obtaining fresh air supplement, and performing deoxygenation and fire extinguishing. The mounting plate 3 is located within the surrounding range of the fireproof outer cover 5, and a uniformly distributed skeleton 51 is fixedly sleeved in the fireproof outer cover 5. 51 maintains the shape of the fireproof outer cover 5, so that the fireproof outer cover 5 can keep the stability of its appearance when it falls to unfold or lifts up to gather. The bottom end of the fireproof outer cover 5 is fixedly connected with a weighting ring 6. Through the weighting ring 6, the gathered fireproof outer cover 5 can provide weight when unfolding, so that the weighting ring 6 can pull the fireproof outer cover 5 to unfold smoothly when falling. Four pull ropes 7 distributed at 90 degrees are fixedly connected to the middle of the inner wall of the weighting ring 6. Four threading holes are opened in the top cover seat 4. The top ends of the four pull ropes 7 are movably passed through the threading holes to the center hole 41 and connected to each other, so that the four pull ropes 7 are gathered together to pull up and gather the fireproof outer cover 5. When there is no fire, the fireproof outer cover 5 will be located above the mounting plate 3 to avoid hindering the normal air convection between the electronic components on the mounting plate 3 and the outside world.

[0023] See also Figure 5 , Figures 7 and 8A center hole 41 is provided at the center of the top cover seat 4, a tool seat 14 is provided below the center hole 41, the tool seat 14 is fixedly connected to the top cover seat 4 by bolts, a movable groove 141 is provided in the tool seat 14, a tool column 15 is movably sleeved in the movable groove 141, so that the movable groove 141 limits the position and movement direction of the tool column 15, an annular cutting edge is provided at the top of the tool column 15, the cutting edge is located below the pull rope 7 in the center hole 41, and a scissors ring 1 is fixedly sleeved at the top of the center hole 41 7. An inclined edge 171 is provided on the outer side of the bottom end of the scissor ring 17 and is opposite to the cutting edge of the knife column 15. The scissor ring 17 is located above the pull rope 7 in the center hole 41, so that when the knife column 15 moves upward, it can shear the pull rope 7 in the center hole 41 through the cutting edge and the inclined edge 171 of the scissor ring 17, so that the pull rope 7 connected to each other is disconnected, so that the weighting ring 6 loses its upward limiting force, driving the gathered fireproof cover 5 to fall and unfold, and surround the mounting plate 3.

[0024] See also Figure 1 to Figure 2 , Figures 4 to 5 , Figures 7 and 8 An exhaust whistle 18 is fixedly connected to the top opening of the center hole 41, so that a large amount of gas below can be discharged through the exhaust whistle 18 when flowing upward, forming a whistle sound for alarm. The shape of the exhaust whistle 18 is a 90-degree curved pipe shape, and the top opening of the exhaust whistle 18 is inclined downward, so that rainwater from the outside cannot enter the distribution cabinet 2 through the top opening of the exhaust whistle 18. There is a gap between the top of the tool seat 14 and the bottom of the top cover seat 4. The top center of the knife column 15 is grooved, and the top of the knife column 15 is provided with exhaust holes 16 evenly distributed around the circumference, so that the gas generated inside after the fireproof outer cover 5 is closed can enter the groove opened on the top of the knife column 15 through the exhaust holes 16, and then enter the exhaust whistle 18 through the center hole 41.

[0025] See also Figure 5 , Figure 7 The bottom end of the tool seat 14 is fixedly connected to a hydraulic box 8, and the hydraulic box 8 is filled with hydraulic oil. The bottom end of the hydraulic box 8 is fixedly connected to a uniformly distributed positioning cylinder 9, and a piston column 10 is movably sleeved in the positioning cylinder 9. A spring 11 is sleeved on the outer side of the piston column 10, and the top of the spring 11 is fixedly connected to the bottom end of the positioning cylinder 9, and the bottom end of the spring 11 is fixedly connected to the bottom of the piston column 10. The top of the positioning cylinder 9 is connected to the inner cavity of the hydraulic box 8, and the inner cavity of the hydraulic box 8 is connected to the bottom of the movable groove 141 through a hose, so that the spring 11 can be stretched and stored when the piston column 10 moves downward. When the piston column 10 loses its downward limiting force, the energy-storing spring 11 can pull the piston column 10 to lift quickly, so that the piston column 10 squeezes the hydraulic oil in the positioning cylinder 9 into the hydraulic box 8, and then enters the movable groove 141 through the hose, pushing the knife column 15 to lift the cutting rope 7.

[0026] See also Figure 2 , Figures 4 to 5 , Figure 7 The bottom end of the piston column 10 is fixedly connected with a sensing rope 12, and the bottom end of the sensing rope 12 is fixedly connected with a limiting plate 13. The top of the base 1 is fixedly connected with evenly distributed L-shaped buckling bodies 25. The limiting plate 13 is inserted into the gap between the L-shaped buckling body 25 and the top of the base 1, so that when the limiting plate 13 is inserted downward into the gap between the L-shaped buckling body 25 and the top of the base 1, the piston column 10 can be pulled downward through the sensing rope 12 to stretch the spring 11 to store energy. At this time, the sensing rope 12 is in a tensioned state, and the sensing rope 12 is close to the mounting plate 3. When the electronic component catches fire, the nearby sensing rope 12 will be ignited, so that the sensing rope 12 is disconnected (the more electronic components are burned, the more induction ropes 12 are disconnected). At this time, the piston column 10 connected to the induction rope 12 loses its downward limiting force and is lifted up by the drive of the spring 11, squeezing the hydraulic oil in the positioning cylinder 9 into the hydraulic box 8 and into the bottom of the movable groove 141, pushing the knife column 15 to lift up, so that the circular blade at the top of the knife column 15 cuts the joint of the upper pull rope 7, and cooperates with the scissor ring 17 to cut the pull rope 7, so that the fireproof outer cover 5 loses its upward limiting force and falls, closing the entire installation plate, reducing the entry of air, thereby reducing the continuous oxygen supply to the fire source, delaying or even extinguishing the flame.

[0027] Embodiment 2 See also Figures 2 to 5 On the basis of the first embodiment, a surrounding recessed groove 22 is provided at the top of the base 1, and the recessed groove 22 is located directly below the weighted ring 6. A liquid capsule 23 is movably sleeved in the recessed groove 22, and the liquid capsule 23 is filled with dilute hydrochloric acid (including but not limited to dilute hydrochloric acid). The inner side of the bottom end of the weighted ring 6 is fixedly connected with evenly distributed ejector pins 21, so that the weighted ring 6 can fall into the recessed groove 22 when falling, and the ejector pins 21 pierce the portion of the liquid capsule 23 close to the recessed groove 22, so that the dilute hydrochloric acid in the liquid capsule 23 can be discharged through the pierced portion, and the weighted ring 6 will squeeze the liquid capsule 23 downward to accelerate the discharge of the dilute hydrochloric acid.

[0028] See also Figures 2 to 6 A marble ring plate 20 is fixedly connected to the bottom of the inner wall of the weighting ring 6, and evenly distributed crushing knives 24 are fixedly connected to the inner side of the top opening of the recessed groove 22. The crushing knives 24 are located directly below the marble ring plate 20, so that when the weighting ring 6 falls, it can drive the marble ring plate 20 to fall, so that the marble ring plate 20 hits the crushing knives 24 and breaks, so that the broken marble ring plate 20 can contact the dilute hydrochloric acid over a large area, thereby accelerating the production rate of carbon dioxide.

[0029] Embodiment 3 See also Figure 2 , Figures 4 to 5 , Figure 7On the basis of the second embodiment, the outer side of the fireproof outer cover 5 is fixedly connected with a uniformly distributed hydraulic hose 19, and the hydraulic hose 19 is connected to the inner cavity of the hydraulic box 8. When the induction rope 12 breaks and the piston column 10 is lifted, a part of the hydraulic oil is input into the movable groove 141 to push the knife column 15 to lift up, and the scissor ring 17 will limit the lifting distance of the knife column 15. At this time, the excess hydraulic oil will be pressed into the hydraulic hose 19, so that the hydraulic hose 19 is quickly unfolded, pushing the fireproof outer cover 5 to quickly unfold downward, avoiding the problem of the fireproof outer cover 5 failing to unfold due to stacking, and the rapid unfolding is conducive to the rapid closure and installation. The plate 3 is installed to quickly form a relatively closed space. During this process, the falling speed of the weighted ring 6 and the marble ring plate 20 will be accelerated, so that the impact force of the ejector pin 21 impacting the liquid bag and the marble ring plate 20 impacting the crushing knife 24 will increase, thereby making the marble ring plate 20 more crushed, and the diffusion rate of the dilute hydrochloric acid increases, further increasing the output rate of carbon dioxide, and improving the fire extinguishing speed. The rapid production of carbon dioxide helps to quickly increase the air pressure in the fireproof outer cover 5, increase the air flow speed through the exhaust whistle 18, and ensure that the alarm sound generated by the exhaust whistle 18 is sufficiently harsh.
