Description

Technical Field

[0001] The present invention belongs to the field of fire protection technology, and particularly relates to a distribution box with fire prevention and extinguishing functions. Background Art

[0002] The distribution box has the characteristics of small volume, simple installation, special technical performance, fixed position, unique configuration function, not restricted by the site, wide application, stable and reliable operation, high space utilization rate, less land occupation and environmental protection effect. It is the control center for rationally distributing electric energy to various components in the power supply line, the control link for reliably receiving the upper-end power supply and correctly feeding out the load electric energy, and also the key to obtaining the user's satisfaction with the power supply quality.

[0003] At present, most of the extinguishing of the distribution box is achieved by introducing liquid carbon dioxide to block the oxygen source for combustion. For example, in the patent with the publication number CN116914577A, the distribution box is mainly sealed to form a closed space inside the box body of the distribution box, and then dry ice in the dry ice storage tank is introduced for extinguishing.

[0004] This method has the following technical problems in use: during extinguishing, due to the sealing of the power distribution cabinet, after carbon dioxide is introduced into the power distribution cabinet, the air and thick smoke in the power distribution cabinet cannot be discharged, resulting in a low carbon dioxide content inside the power distribution cabinet and a reduced extinguishing efficiency; if the thick smoke cannot be discharged from the power distribution cabinet, the particulate matter in the thick smoke will adhere to the circuit board of the electronic equipment, causing secondary damage to the electrical appliances. Summary of the Invention

[0005] The purpose of the present invention is to provide a distribution box with fire prevention and extinguishing functions for the deficiencies of the existing technology to solve the technical problems in the existing technology.

[0006] The purpose of the present invention can be achieved by the following technical solutions: a distribution box with fire prevention and extinguishing functions, which includes a box body. A cabinet door is installed on the box body, and the cabinet door is hermetically connected to the box body. Ventilation groove groups are opened on the side walls of the box body, and the groove width of the ventilation groove groups gradually increases from the bottom to the top of the box body. A mother board is installed inside the box body, and a photoelectric sensor is installed on the mother board. The photoelectric sensor is respectively connected to a buzzer and a cylinder; a plugging component is slidably installed on the box body. The plugging component includes a U-shaped plate. A plurality of exhaust grooves are equidistantly opened on the side walls of the U-shaped plate. The exhaust grooves cooperate with the ventilation groove groups. A cylinder is installed inside the box body, and the cylinder controls the lifting of the U-shaped plate. A gas storage tank is installed on the U-shaped plate, and the gas storage tank transports the liquid to the bottom of the box body through a special-shaped conduit.

[0007] As a further optimization or improvement of this solution, guide bars are installed on both sides of the box body, and the guide bars are slidably matched with the side walls of the U-shaped plate.

[0008] As a further optimization or improvement of this solution, studs are installed on the U-shaped plate, and an exhaust component is installed on the top of the box body. The exhaust component is in driving cooperation with the studs.

[0009] As a further optimization or improvement of this solution, the exhaust component includes a ventilation top plate and a ventilation bottom plate. The ventilation top plate is fixedly installed on the box body, and the ventilation bottom plate is rotatably installed on the ventilation top plate. The stud is in driving cooperation with the ventilation bottom plate.

[0010] As a further optimization or improvement of this solution, a sealing gasket is installed at the bottom of the U-shaped plate, and the U-shaped plate seals the ventilation top plate through the sealing gasket.

[0011] As a further optimization or improvement of this solution, a guiding plate is installed on the U-shaped plate, a guiding groove is formed on the box body, the guiding plate is located inside the guiding groove and slides, and the air cylinder is connected to the U-shaped plate through the guiding plate.

[0012] As a further optimization or improvement of this solution, a pipe groove is formed on the box body, and the special-shaped conduit is inserted into the box body through the pipe groove, so that the exhaust end of the special-shaped conduit is placed at the bottom of the box body.

[0013] Advantages of the present invention: (1) The gas storage tank of the present invention transports carbon dioxide to the bottom of the box body through the special-shaped conduit. Since the molecular mass of carbon dioxide is greater than that of air, carbon dioxide will diffuse from the bottom to the top of the box body, and the air inside the box body will be discharged from the box body through the ventilation groove group and the exhaust groove.

[0014] Specifically, during the process of carbon dioxide diffusing from the bottom to the top of the box body, the ventilation groove group from the bottom to the top of the box body is gradually blocked by the U-shaped plate, so that while carbon dioxide discharges the gas inside the box body, it avoids the discharge of carbon dioxide gas from the box body, ensures the concentration of carbon dioxide inside the box body, and guarantees the fire extinguishing efficiency of the present invention.

[0015] (2) When the air cylinder in the present invention drives the U-shaped plate to move downward, the U-shaped plate drives the stud to move downward synchronously. Under the driving cooperation of the stud and the ventilation bottom plate, the U-shaped plate drives the ventilation bottom plate to rotate through the stud, so that the through holes on the ventilation bottom plate gradually coincide with the through holes on the ventilation top plate, and the thick smoke is discharged outwards through the through holes on the ventilation bottom plate and the ventilation top plate; when the gas storage tank transports carbon dioxide to the bottom of the box body through the special-shaped conduit, the carbon dioxide inside the box body will accelerate the discharge of the thick smoke.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] See Figures 1 - 6 , a distribution box with fire prevention and fire extinguishing functions, which includes a box body 1, the box body 1 is installed with a cabinet door 2, the cabinet door 2 is hermetically connected to the box body 1, a ventilation groove group 4 is opened on the side wall of the box body 1, and the groove width of the ventilation groove group 4 gradually increases from the bottom to the top of the box body 1. A mother board 9 is installed in the box body 1, and a photoelectric sensor 10 is installed on the mother board 9. The photoelectric sensor 10 is respectively connected to a buzzer 11 and a cylinder 12; a plugging component 6 is slidably installed on the box body 1. The plugging component 6 includes a U-shaped plate 601, and a plurality of exhaust grooves 602 are equidistantly opened on the side wall of the U-shaped plate 601. The exhaust grooves 602 cooperate with the ventilation groove group 4. A cylinder 12 is installed in the box body 1, and the cylinder 12 controls the lifting of the U-shaped plate 601. A gas storage tank 603 is installed on the U-shaped plate 601, and the gas storage tank 603 transports the liquid to the bottom of the box body 1 through a special-shaped conduit 607.

[0027] Specifically, a sealing gasket 605 is installed at the bottom of the U-shaped plate 601 , and the U-shaped plate 601 seals the ventilation top plate 501 through the sealing gasket 605 .

[0028] Specifically, guide bars 3 are installed on both sides of the box body 1 , and the guide bars 3 are slidably matched with the side walls of the U-shaped plate 601 .

[0029] It should be noted that see Figure 2 The ventilation groove group 4 includes a bottom groove 401, a middle lower groove 402, a middle groove 403, a middle upper groove 404 and a top groove 405, and the groove width gradually increases from the bottom groove 401 to the top groove 405; when no fire occurs, the two side walls of the box body 1 are in a ventilation state, that is, the bottom groove 401 to the top groove 405 overlap with the exhaust groove 602 respectively, so that the convection gas enters and exits the box body 1 through the exhaust groove 602 and the ventilation groove group 4, thereby achieving the purpose of heat dissipation of the motherboard 9.

[0030] It should be noted that under normal conditions (when no fire occurs), see Figure 5 At this time, the exhaust grooves 602 on the side wall of the U-shaped plate 601 overlap with the ventilation groove group 4 on the box body 1. External air enters the box body 1 through the exhaust grooves 602 and the ventilation groove group 4, so that the motherboard 9 dissipates heat. When there is no fire, the through holes on the ventilation top plate 501 and the ventilation bottom plate 502 are staggered to make the top of the box body 1 sealed and prevent dust from falling into the box body 1.

[0031] The photoelectric sensor 10 can detect fire. If a fire occurs inside the box 1, the photoelectric sensor 10 controls the cylinder 12 and the buzzer 11 to operate, and at the same time, the gas tank 603 delivers carbon dioxide to the bottom of the box 1 through the special-shaped conduit 607. Since the molecular mass of carbon dioxide is greater than that of air, carbon dioxide will diffuse upward from the bottom of the box 1, and the air inside the box 1 will be discharged from the box 1 through the ventilation groove group 4 and the exhaust groove 602.

[0032] At the same time, when the cylinder 12 is running, the cylinder 12 drives the U-shaped plate 601 to move downward through the guide plate 604. During the downward movement of the U-shaped plate 601, the exhaust groove 602 on the U-shaped plate 601 is gradually offset from the ventilation groove group 4. Since the groove width of the ventilation groove group 4 gradually increases from the bottom to the top of the box body 1, during the downward movement of the U-shaped plate 601, the exhaust groove 602 at the bottom of the U-shaped plate 601 is first offset from the ventilation groove group 4, so that the U-shaped plate 601 blocks the ventilation groove group 4 at the bottom of the box body 1. As the U-shaped plate 601 continues to move downward, the ventilation groove group 4 from the bottom of the box body 1 to the top of the box body 1 is gradually blocked by the U-shaped plate 601.

[0033] During the diffusion of carbon dioxide from the bottom to the top of the box body 1, the ventilation groove group 4 from the bottom to the top of the box body 1 is gradually blocked by the U-shaped plate 601, so that the carbon dioxide can discharge the internal gas of the box body 1 while preventing the carbon dioxide gas from being discharged from the box body 1, thereby ensuring the concentration of carbon dioxide inside the box body 1.

[0034] As the U-shaped plate 601 moves downward, the U-shaped plate 601 contacts the top of the box body 1. At this time, the gasket 605 on the U-shaped plate 601 blocks the smoke exhaust assembly 5, and at the same time, the side wall of the U-shaped plate 601 blocks the entire ventilation groove group 4, making the box body 1 in a sealed state. At this time, the gas and thick smoke inside the box body 1 are basically exhausted. Without damaging the box body 1, the concentration of carbon dioxide inside the box body 1 is effectively increased, and the fire extinguishing efficiency is improved.

[0035] See Figures 4 - 7 , a stud 606 is installed on the U-shaped plate 601, and the smoke exhaust assembly 5 is installed on the top of the box body 1, and the smoke exhaust assembly 5 is in driving cooperation with the stud 606.

[0036] Specifically, the smoke exhaust assembly 5 includes a ventilation top plate 501 and a ventilation bottom plate 502. The ventilation top plate 501 is fixedly installed on the box body 1, the ventilation bottom plate 502 is rotatably installed on the ventilation top plate 501, and the stud 606 is in driving cooperation with the ventilation bottom plate 502.

[0037] It should be noted that when a fire generates thick smoke, it is usually affected by the rising hot air and diffuses upward, causing it to gather at the top of the box body 1. In order to avoid secondary damage to electrical appliances caused by the thick smoke gathered in the box body 1. Based on this, when the cylinder 12 of the present invention drives the U-shaped plate 601 to move downward, the U-shaped plate 601 drives the stud 606 to move downward synchronously. Under the driving cooperation between the stud 606 and the ventilation bottom plate 502, the U-shaped plate 601 drives the ventilation bottom plate 502 to rotate through the stud 606, so that the through holes on the ventilation bottom plate 502 gradually coincide with the through holes on the ventilation top plate 501, and the thick smoke is discharged out through the through holes on the ventilation bottom plate 502 and the ventilation top plate 501; when the gas storage tank 603 transports carbon dioxide to the bottom of the box body 1 through the special-shaped conduit 607, the carbon dioxide inside the box body 1 will accelerate the discharge of the thick smoke.

[0038] It should be noted that if the box body 1 is installed indoors, the box body 1 needs to be arranged near the ventilation duct so that the thick smoke can be discharged to the outside through the ventilation system, avoiding physical damage to the staff caused by the thick smoke; if the box body 1 is installed outdoors, there is no requirement.

[0039] See Figures 2 - 6 , a guide plate 604 is installed on the U-shaped plate 601, a guide groove 7 is opened on the box body 1, and the guide plate 604 is located in the guide groove 7 and slides, and the cylinder 12 is connected to the U-shaped plate 601 through the guide plate 604.

[0040] Specifically, a pipe groove 8 is opened on the box body 1, and the special-shaped conduit 607 is inserted into the box body 1 through the pipe groove 8, so that the exhaust end of the special-shaped conduit 607 is placed at the bottom of the box body 1.

[0041] It should be noted that, since the molecular mass of carbon dioxide is greater than that of air, when the gas storage tank 603 transports carbon dioxide to the bottom of the box 1 through the special-shaped conduit 607, the carbon dioxide will diffuse upward from the bottom of the box 1 and discharge the air inside the box 1 out of the box 1 through the ventilation groove group 4 and the exhaust groove 602.

[0042] The implementation principle of the present invention is: under normal conditions (when no fire occurs), refer to Figure 5 At this time, the exhaust grooves 602 on the side wall of the U-shaped plate 601 overlap with the ventilation groove group 4 on the box body 1 one by one, and the external air enters and exits the box body 1 through the exhaust grooves 602 and the ventilation groove group 4, so that the motherboard 9 dissipates heat. When there is no fire, the through holes on the ventilation top plate 501 and the ventilation bottom plate 502 are staggered to make the top of the box body 1 sealed to prevent dust from falling into the box body 1.

[0043] The photoelectric sensor 10 can detect fire. If a fire occurs inside the box 1, the photoelectric sensor 10 controls the cylinder 12 and the buzzer 11 to operate, and at the same time, the gas tank 603 delivers carbon dioxide to the bottom of the box 1 through the special-shaped conduit 607. Since the molecular mass of carbon dioxide is greater than that of air, carbon dioxide will diffuse upward from the bottom of the box 1, and the air inside the box 1 will be discharged from the box 1 through the ventilation groove group 4 and the exhaust groove 602. At the same time, when the cylinder 12 is running, the cylinder 12 drives the U-shaped plate 601 to move downward through the guide plate 604. During the downward movement of the U-shaped plate 601, the exhaust groove 602 on the U-shaped plate 601 is gradually offset from the ventilation groove group 4. Since the groove width of the ventilation groove group 4 gradually increases from the bottom to the top of the box body 1, during the downward movement of the U-shaped plate 601, the exhaust groove 602 at the bottom of the U-shaped plate 601 is first offset from the ventilation groove group 4, so that the U-shaped plate 601 blocks the ventilation groove group 4 at the bottom of the box body 1. As the U-shaped plate 601 continues to move downward, the ventilation groove group 4 from the bottom of the box body 1 to the top of the box body 1 is gradually blocked by the U-shaped plate 601.

[0044] During the diffusion of carbon dioxide from the bottom to the top of the box body 1, the ventilation groove group 4 from the bottom to the top of the box body 1 is gradually blocked by the U-shaped plate 601, so that the carbon dioxide can discharge the internal gas of the box body 1 while preventing the carbon dioxide gas from being discharged from the box body 1, thereby ensuring the concentration of carbon dioxide inside the box body 1 and guaranteeing the fire extinguishing efficiency of the present invention.

[0045] Specifically, when the cylinder 12 drives the U-shaped plate 601 to move downward, the U-shaped plate 601 drives the stud 606 to move downward synchronously. Under the transmission cooperation between the stud 606 and the ventilation chassis 502, the U-shaped plate 601 drives the ventilation chassis 502 to rotate through the stud 606, so that the through holes on the ventilation chassis 502 gradually overlap with the through holes on the ventilation top plate 501, so that the thick smoke is discharged outward through the through holes on the ventilation chassis 502 and the ventilation top plate 501; when the gas storage tank 603 transports carbon dioxide to the bottom of the box body 1 through the special-shaped conduit 607, the carbon dioxide inside the box body 1 will accelerate the discharge of thick smoke.

[0046] As the U-shaped plate 601 moves downward, the U-shaped plate 601 contacts the top of the box body 1. At this time, the gasket 605 on the U-shaped plate 601 blocks the smoke exhaust assembly 5, and at the same time, the side wall of the U-shaped plate 601 blocks all the ventilation grooves 4, making the box body 1 in a sealed state. At this time, the gas and thick smoke inside the box body 1 are basically exhausted. Without damaging the box body 1, the concentration of carbon dioxide inside the box body 1 is effectively increased, and the fire extinguishing efficiency is improved.

[0047] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
