Description

Technical Field

[0001] This invention relates to the field of fireproofing technology for electrical distribution boxes, specifically to an electrical distribution box with heat dissipation and noise reduction capabilities. Background Technology

[0002] The distribution box is the core electrical device that receives the main power supply and distributes the power to each independent circuit in an orderly manner. It belongs to the final stage equipment of the power distribution system. It is like a "power traffic policeman", which coordinates the current and distributes it to the power terminals such as lights, sockets and home appliances. At the same time, it monitors the circuit status and immediately cuts off the power protection when there is a risk of overload, short circuit or leakage.

[0003] Distribution boxes with heat dissipation and noise reduction functions are special distribution boxes designed for noise-sensitive locations. While ensuring normal heat dissipation of electrical components, they effectively suppress the transmission of noise from inside the box. They are commonly used in residential buildings, office buildings, hospitals, hotels, and other areas that require a quiet environment.

[0004] During long-term use, current distribution boxes are affected by ambient temperature, mechanical vibration, and the aging of electrical components, which can lead to loose contacts, oxidation, or decreased insulation performance. This can cause irregular discharges, which can heat up and ignite internal flammable materials. Existing protection measures rely on overload or short-circuit protection to automatically cut off the power. However, this operation can only cut off the power but cannot effectively extinguish the flames that have already formed, causing the fire to continue to spread, burn critical electrical components inside the box, and cause irreversible damage to the equipment and high replacement costs.

[0005] To address the above issues, a power distribution box with heat dissipation and noise reduction features is proposed. Summary of the Invention

[0006] The purpose of this invention is to provide a power distribution box with heat dissipation and noise reduction. By using this device, the problem in the background is that during long-term use of the power distribution box, the environmental temperature, mechanical vibration and component aging cause loosening of contacts, oxidation or decreased insulation, resulting in irregular discharge, heat generation and ignition of internal combustibles. Existing overload or short circuit protection can only achieve automatic power cut-off, but cannot extinguish the flames that have already started, causing the fire to continue to spread, burn key electrical components, and cause irreversible damage and high costs.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a power distribution box with heat dissipation and noise reduction, comprising a power distribution box body, a louvered plate rotatably connected to one outer wall of the power distribution box body, a drive sleeve assembly fixedly connected to the end of the louvered plate, a self-closing cooling fan fixedly connected to the other outer wall of the power distribution box body, a screen bracket fixedly connected to the inner wall of the power distribution box body, an inlet sleeve snapped into the bottom of the power distribution box body, a conveyor line inserted into the inside of the inlet sleeve, a temperature sensor fixedly connected to the inner wall of the power distribution box body, an electric push rod rotatably connected to the surface of the louvered plate, the electric push rod rotatably connected to one outer wall of the power distribution box body, a suction flame-retardant assembly fixedly connected to the outer surface of the power distribution box body, and an auxiliary flame-extinguishing assembly movably connected to the surface of the conveyor line.

[0008] Furthermore, the drive sleeve assembly includes a fixed shaft fixedly connected to the center of both ends of the louver, a linkage telescopic plate fixedly connected to the end of the fixed shaft, the fixed shaft being rotatably connected to the distribution box, and a push sliding plate rotatably connected to one end of the linkage telescopic plate, the push sliding plate being slidably connected inside the distribution box.

[0009] Furthermore, each end of the louver is rotatably connected to a first connector, one end of the first connector is fixedly connected to a telescopic rod, and one end of the telescopic rod is fixedly connected to a second connector.

[0010] Furthermore, a transmission spring is sleeved on the outer surface of the telescopic rod, and the two ends of the transmission spring are fixedly connected to the ends of the first connector and the second connector, respectively. One end of the second connector is rotatably connected to a lifting frame, and the lifting frame is connected through the screen support.

[0011] Furthermore, the suction flame-retardant assembly includes a suction canister fixedly connected to the outer wall of the other side of the distribution box. A piston plate is slidably connected inside the suction canister. A piston rod is fixedly connected to the top of the piston plate. The surface of the piston rod is slidably connected to the top of the suction canister. A limit plate is fixedly connected to the bottom of the piston plate. A high-pressure spring is fixedly connected to the bottom of the limit plate. One end of the high-pressure spring is fixedly connected to the bottom of the inner wall of the suction canister.

[0012] Furthermore, an air intake chamber is inserted into the side wall of the air intake tank, one end of which is inserted into the inside of the electrical distribution box. A one-way air intake valve is fixedly connected to the end of the air intake chamber. A one-way air outlet valve is inserted into the bottom axis of the air intake tank, and an exhaust valve is inserted into the side wall of the air intake tank.

[0013] Furthermore, a locking block is rotatably connected to the inner wall of the air intake tank, a return spring is fixedly connected to the side of the locking block, one end of the return spring is fixedly connected to the inner wall of the air intake tank, an elastic top block is rotatably connected to the end of the locking block, and a first metal rope is fixedly connected to the side of the locking block, one end of the first metal rope is fixedly connected to the bottom of the lifting frame.

[0014] Furthermore, the auxiliary fire extinguishing assembly includes a fixing block fixedly connected to the top of the inlet bushing, a first clamping plate fixedly connected to the top of the fixing block, a lifting rod slidably connected inside the first clamping plate, a second metal rope fixedly connected to the top of the lifting rod, and one end of the second metal rope fixedly connected to the bottom of the lifting frame.

[0015] Furthermore, a second clamping plate is hinged to one end of the first clamping plate, and a clamping plate torsion spring is fixedly connected between the first clamping plate and the second clamping plate. A torsion spring shaft is rotatably connected to the ends of both the first clamping plate and the second clamping plate. Several pairs of clamping frames are fixedly connected to the ends of the torsion spring shafts, and the clamping frames are tightly fitted to the surface of the conveyor line.

[0016] Furthermore, a tree branch bracket is fixedly connected to the bottom of the lifting rod, a connecting plate is fixedly connected to the end of the tree branch bracket, a flame-retardant cavity is fixedly connected to the bottom of the connecting plate, and the flame-retardant cavity is fixedly connected to the bottom of the distribution box and slidably connected to the incoming line bushing.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention incorporates a suction flame-retardant assembly linked to a louvered panel. When a temperature sensor detects an abnormal temperature rise, an electric push rod drives the louvered panel to flip and close. Simultaneously, the self-closing cooling fan is powered off and shuts down, creating a relatively sealed environment within the distribution box. Subsequently, the piston plate in the suction flame-retardant assembly rises under the action of a high-pressure spring, continuously drawing air from the box through a one-way air intake valve, effectively reducing the oxygen concentration and suppressing flame combustion. At the same time, the clamping frame in the auxiliary flame-extinguishing assembly forms a tight wrap around the surface of the conveyor line. After the insulation layer melts, the inner core is elastically clamped by a torsion spring shaft, using physical striking and isolation effects to block the spread of flames along the line and prevent the fire from spreading.

[0018] By driving the linkage telescopic plate, the top sliding plate, and the lifting frame structure in the drive sleeve assembly, the flipping power of the louvered plate is converted into the synchronous mechanical driving force of multiple components. These components control the locking block in the suction flame retardant assembly to release the piston plate, and assist the lifting rod in the fire extinguishing assembly to pull the second metal rope. At the same time, the air suction and conveyor wrapping actions are initiated. This linkage can be completed with a single drive of the electric push rod, eliminating the need for a backup power supply inside the distribution box. This reduces system complexity and cost, avoids secondary risks that backup power supplies may cause in a fire, and improves overall reliability and safety.

[0019] When the distribution box is working normally, fresh air from outside is introduced through the louvers, and forced exhaust is achieved in conjunction with the self-closing cooling fan, achieving efficient heat dissipation. At the same time, the screen bracket intercepts environmental impurities, ensuring cleanliness inside the box and reducing the risk of discharge caused by dust accumulation. When the temperature sensor records abnormal temperature rise data, it can provide accurate historical temperature records for subsequent maintenance personnel, facilitating quick location of faults. In addition, the closing action of the louvers and the self-closing cooling fan is automatically executed in the event of a fire, realizing daily noise reduction and emergency fire extinguishing needs, and improving the applicability and maintenance efficiency of the distribution box in noise-sensitive locations.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] like Figures 1-15As shown, the following preferred technical solution is provided: A power distribution box with heat dissipation and noise reduction, including a power distribution box body 1. The power distribution box body 1 provides stable support and housing space for the device, facilitating the coordinated operation of various electrical components. A louvered plate 2 is rotatably connected to one outer wall of the power distribution box body 1. The louvered plate 2 is used to introduce gas from the external environment, facilitating the input of fresh gas into the interior of the power distribution box body 1 and timely replacement of the internal gas. A drive sleeve assembly 6 is fixedly connected to the end of the louvered plate 2. The drive sleeve assembly 6 drives multiple louvered plates 2 to rotate synchronously. After the multiple synchronously rotating louvered plates 2 rotate to a specified angle, the tail ends of the louvered plates 2 gradually contact each other and adhere to each other, so that the power distribution box body 1 is affected by the rotation of multiple louvered plates 2. After being fitted together, a closed state is formed at the air inlet at the end of the distribution box 1, thereby preventing ambient gas from entering the distribution box 1. At the same time, after the drive sleeve assembly 6 is running, it provides power conditions for the operation of subsequent devices. A self-closing cooling fan 3 is fixedly connected to the outer wall of the other side of the distribution box 1. The self-closing cooling fan 3 is used to transport the air inside the distribution box 1 to the outside of the distribution box 1 during normal operation. According to the publication number CN206571710U, the self-closing cooling fan 3 is the prior art. When a fire occurs inside the distribution box 1 and combustion occurs, the self-closing cooling fan 3 stops supplying power, realizes the sealing function, and stops the suction and evacuation of the air inside the distribution box. like Figures 2-4 As shown, a screen support 4 is fixedly connected to the inner wall of the distribution box 1. The screen support 4 is used to intercept impurities in the ambient air, preventing impurities from generating too much dust in the distribution box 1, ensuring the cleanliness of the environment in the distribution box 1, and preventing impurities from coming into contact with the current and causing an explosion or combustion. An inlet sleeve 5 is snapped onto the bottom of the distribution box 1. A conveyor line 9 is inserted into the inside of the inlet sleeve 5. The conveyor line 9 conveys the power into the distribution box 1 through the inlet sleeve 5, achieving directional conveying. At the same time, the conveyor line 9 can fit tightly with the inlet sleeve 5, isolating impurities and moisture in the external environment and ensuring a sealing effect. A temperature sensor 10 is fixedly connected to the inner wall of the distribution box 1. The temperature sensor 10 is used to monitor the temperature changes in the distribution box 1 in real time, which is conducive to better responding to sudden fires, giving the equipment time to react, and speeding up the response to emergencies. At the same time, the setting of the temperature sensor 10 also facilitates the accurate recording of the temperature changes inside the distribution box 1, which is convenient for subsequent maintenance personnel to promptly detect abnormal temperature records and facilitate inspection. like Figures 1-4As shown, an electric push rod 11 is rotatably connected to the surface of the louvered plate 2. The electric push rod 11 is rotatably connected to the outer wall of one side of the distribution box 1. The electric push rod 11 provides a stable driving force for the equipment. A suction flame-retardant assembly 7 is fixedly connected to the outer surface of the distribution box 1. The suction flame-retardant assembly 7 cooperates with the temperature sensor 10. When the temperature sensor 10 detects a significant and continuous increase in the temperature inside the distribution box 1, it transmits an electrical signal to the electric push rod 11, causing the electric push rod 11 to push the louvered plate 2 to flip, forming a tight fit and closing the air inlet. At the same time, the self-closing cooling fan 3 shuts down, achieving a relatively sealed effect inside the distribution box 1. Then, the suction flame-retardant assembly 7... Air is drawn out of the electrical box 1 to reduce the oxygen content and cut off the necessary conditions for flame combustion, thereby blocking the combustion. An auxiliary flame extinguishing component 8 is movably connected to the surface of the conveyor line 9. When the surface of the conveyor line 9 is overheated due to overload, insulation damage causing local high temperature or open flame, the auxiliary flame extinguishing component 8 can tightly wrap and flame-retardantly cover the surface of the conveyor line 9 through mechanical linkage, cutting off the path of flame spread along the conveyor line 9. Furthermore, when the outer skin of the conveyor line 9 is melted, the auxiliary flame extinguishing component 8 can achieve sequential single-stage pressure on the ignition point during the downward movement of the flame. At the same time, in conjunction with the negative pressure suction of the suction flame retardant component 7, the fire source is quickly suffocated, preventing the fire from spreading along the line.

[0024] like Figures 2-6 As shown, the drive sleeve assembly 6 includes a fixed shaft 61 fixedly connected to the center of both ends of the louver 2. A linkage telescopic plate 62 is fixedly connected to the end of the fixed shaft 61. The fixed shaft 61 is rotatably connected to the distribution box 1. A push-slide plate 63 is rotatably connected to one end of the linkage telescopic plate 62. The push-slide plate 63 is slidably connected inside the distribution box 1. When the louver 2 is flipped, the fixed shaft 61 starts to drive the linkage telescopic plate 62 to flip along with the louver 2. As the linkage telescopic plate 62 rotates, the push-slide plate 63 is pushed by the flipping force of the linkage telescopic plate 62 and slides vertically inside the distribution box 1. This enables the push-slide plate 63 to drive multiple sets of louver 2 to flip synchronously, ensuring that the flipping angle of all louver 2 is consistent and improving the sealing effect.

[0025] like Figures 3-6 As shown, each end of the louver 2 is rotatably connected to a first connector 64. One end of the first connector 64 is fixedly connected to a telescopic rod 65, and one end of the telescopic rod 65 is fixedly connected to a second connector 67. When the electric push rod 11 pushes the louver 2 to rotate, the first connector 64 rotates with the louver 2 and transmits power to the second connector 67 through the telescopic rod 65. The telescopic rod 65 can adaptively adjust its length to compensate for the displacement generated during the rotation of the louver 2 and ensure smooth power transmission.

[0026] like Figures 4-6 As shown, a transmission spring 66 is sleeved on the outer surface of the telescopic rod 65. The two ends of the transmission spring 66 are fixedly connected to the ends of the first connector 64 and the second connector 67, respectively. One end of the second connector 67 is rotatably connected to a lifting frame 68, which is connected through the screen support 4. The transmission spring 66 provides elastic compensation force during the extension and retraction of the telescopic rod 65, absorbing the impact during movement, while maintaining continuous elastic tension. As the second connector 67 rotates, the lifting frame 68 slides vertically in the screen support 4, providing mechanical linkage driving force for the subsequent suction flame-retardant component 7 and auxiliary flame-extinguishing component 8. This enables a single power source to drive multiple components to work together. Compared to having a backup power supply in the distribution box 1, this drive sleeve component 6 achieves the driving operation of the entire device through a single driving force, avoiding the need for a backup power supply in the distribution box and reducing the superposition of risks.

[0027] like Figures 2-9 As shown, the suction flame-retardant assembly 7 includes a suction tank 71 fixedly connected to the outer wall of the other side of the distribution box 1. A piston plate 72 is slidably connected inside the suction tank 71. A piston rod 713 is fixedly connected to the top of the piston plate 72. The surface of the piston rod 713 is slidably connected to the top of the suction tank 71. A limit plate 73 is fixedly connected to the bottom of the piston plate 72. A high-pressure spring 77 is fixedly connected to the bottom of the limit plate 73. One end of the high-pressure spring 77 is fixedly connected to the bottom of the inner wall of the suction tank 71. As the louvers 2 and the self-closing cooling fan 3 close, no air enters the distribution box 1, and the temperature is transferred... When sensor 10 alarms, the power supply to the distribution box 1 has not yet been cut off. Therefore, when the electric push rod 11 pushes the louver 2 to flip and close, the self-closing cooling fan 3 will start to cut off the power. At this time, since the louver 2 is closed, no air enters. Therefore, the self-closing cooling fan 3 draws some air from the distribution box 1 to the outside of the distribution box 1 while rotating. As the louver 2 flips, the suction flame-retardant component 7 is activated, and the limit plate 73 begins to disengage. Under the action of the high-pressure spring 77, it is pushed inside the suction tank 71, driving the piston plate 72 to slide upward. Then, the piston plate 72 drives the piston rod 713 to move upward synchronously.

[0028] like Figures 4-9As shown, an air intake chamber 74 is inserted into the side wall of the intake tank 71. One end of the air intake chamber 74 is inserted into the interior of the distribution box 1. A one-way air intake valve 75 is fixedly connected to the end of the air intake chamber 74. A one-way air outlet valve 76 is inserted into the bottom axis of the intake tank 71. An exhaust valve 78 is inserted into the side wall of the intake tank 71. As the piston plate 72 slowly moves upward, the suction force generated causes the one-way air intake valve 75 in the air intake chamber 74 to open, and then the distribution box... The air inside is slowly drawn into the intake chamber 74 through the one-way intake valve 75, and then drawn into the intake tank 71 for continuous storage. As the piston plate 72 rises, the air in the upper part of the intake tank 71 is squeezed out of the exhaust valve 78 and discharged into the external environment. The one-way exhaust valve 76 at the bottom axis of the intake tank 71 discharges the gas below the piston plate 72 in the intake tank 71 into the environment when the piston plate 72 is reset.

[0029] like Figures 5-10 As shown, a locking block 79 is rotatably connected to the inner wall of the air intake tank 71. A return spring 710 is fixedly connected to the side of the locking block 79. One end of the return spring 710 is fixedly connected to the inner wall of the air intake tank 71. An elastic top block 711 is rotatably connected to the end of the locking block 79. A first metal rope 712 is fixedly connected to the side of the locking block 79. One end of the first metal rope 712 is fixedly connected to the bottom of the lifting frame 68. When the louvered plate 2 flips, the lifting frame 68 drives the first metal rope. 712. As the first metal rope 712 is pulled, the locking block 79 begins to flip on the inner wall of the intake tank 71. The return spring 710 is compressed, and the elastic top block 711 flips away from the top surface of the limit plate 73 along with the locking block 79. The limit plate 73 is released from its limit, and the piston plate 72 is slowly raised by the action of the high-pressure spring 77. It performs suction inside the intake tank 71, and the air inside the distribution box 1 is drawn in, reducing the oxygen content in the distribution box 1 and suppressing the combustion of the flame.

[0030] like Figures 4-14 As shown, the auxiliary fire extinguishing assembly 8 includes a fixing block 81 fixedly connected to the top of the inlet sleeve 5. A first clamping plate 82 is fixedly connected to the top of the fixing block 81. A lifting rod 87 is slidably connected inside the first clamping plate 82. A second metal rope 811 is fixedly connected to the top of the lifting rod 87. One end of the second metal rope 811 is fixedly connected to the bottom of the lifting frame 68. When the louvered plate 2 flips, the second metal rope 811 is simultaneously pulled by the lifting frame 68, and then the lifting rod 87 in the first clamping plate 82 is pulled to a specified height. The fixing block 81 is used to provide a stable support for the first clamping plate 82.

[0031] like Figures 5-14As shown, a second clamping plate 83 is hinged to one end of the first clamping plate 82. A clamping plate torsion spring 84 is fixedly connected between the first clamping plate 82 and the second clamping plate 83. A torsion spring shaft 85 is rotatably connected to the ends of both the first clamping plate 82 and the second clamping plate 83. Several pairs of clamping frames 86 are fixedly connected to the ends of the torsion spring shaft 85. The clamping frames 86 are tightly attached to the surface of the conveyor line 9. Through the elastic force of the clamping plate torsion spring 84, the clamping frames 86 on the first clamping plate 82 and the second clamping plate 83 form a circumferential wrap, tightly clamping the surface of the conveyor line 9. At the same time, the torsion spring shaft 85 gives each pair of clamping frames 86 an independent elastic clamping force. The multiple sets of clamping frames 86 on the first clamping plate 82 and the second clamping plate 83... The clamping frame 86 is synchronously held on the surface of the conveyor line 9. When the flame spreads to the conveyor line 9 and burns the outer rubber material of the conveyor line 9, the rubber material of the conveyor line 9 melts, and the clamping frame 86 loses its support. Under the elastic force of the torsion spring shaft 85, the clamping frame 86 will clamp into the inner core of the conveyor line 9 to achieve the effect of holding and pressing the flame. At the same time, combined with the suction flame-retardant component 7, the air inside the distribution box is sucked, causing the oxygen content to drop sharply. After being hit by the clamping frame 86, the flame is again subjected to the physical flame-retardant effect, so that it is extinguished as soon as possible. At the same time, the clamping of multiple clamping frames 86 on the conveyor line 9 forms a physical isolation, blocking flammable materials and reducing the fire. In addition, multiple sets of clamping frames 86 clamp in sequence, forming multiple clamping and pressing, and achieving the effect of extinguishing the fire.

[0032] like Figures 9-15 As shown, a tree branch support 88 is fixedly connected to the bottom of the lifting rod 87, and a connecting plate 89 is fixedly connected to the end of the tree branch support 88. A flame-retardant cavity 810 is fixedly connected to the bottom of the connecting plate 89. The flame-retardant cavity 810 is fixedly connected to the bottom of the distribution box 1 and is slidably connected to the inlet sleeve 5. As the second metal rope 811 is pulled, the lifting rod 87 drives the tree branch support 88 to move upward. As the tree branch support 88 rises, the connecting plate 89 pulls up along with the bottom of the flame-retardant cavity 810. However, because the upper space of the flame-retardant cavity 810 is blocked by the bottom of the distribution box 1, The flame-retardant elastic material in the flame-retardant cavity 810 begins to expand in the inlet bushing 5, filling the internal space of the inlet bushing 5, further enhancing the sealing effect, preventing air penetration, and accelerating the fire extinguishing process in the distribution box 1. After the fire inside the distribution box 1 is extinguished, the electric push rod 11 is controlled to reset, and then the louvered plate 2 is rotated. At the same time, the reset is achieved in conjunction with the drive sleeve assembly 6. Then, the maintenance personnel manually press the piston rod 713 in the suction flame-retardant assembly 7 to make the piston plate 72 continue to move to the bottom of the suction tank 71 and engage with the elastic top block 711 to achieve the limit, thus completing the reset operation.
