Description

Technical Field

[0001] The present invention relates to the technical field of circuit breakers, in particular to a circuit breaker device with a fire protection function. Background Art

[0002] A circuit breaker is an electrical protection device that can automatically cut off the current when an overload, short circuit or other abnormal situation occurs in the circuit to protect the circuit and connected equipment. The working principle of the circuit breaker is mainly based on the combined action of electromagnetic force and spring force, as well as thermal effects and electronic control technology. The protection devices inside the circuit breaker, such as electromagnetic releases, thermal releases and electronic releases, can trigger the circuit breaker's tripping mechanism when abnormal current is detected to quickly cut off the power supply. A circuit breaker with fire protection function is a circuit protection device. It not only has the overload and short circuit protection functions of traditional circuit breakers, but is also specially designed with fire protection functions.

[0003] For example, a circuit breaker device with a fire prevention function disclosed in Chinese patent CN116313659A, after power is turned on, the motor will start working, thereby driving the air intake fan and the air outlet fan to work, and the airflow generated by the rotation of the fan will blow up the movable baffle. At the same time, the airflow generated by the rotation of the air intake fan and the air outlet fan will form an air duct to enhance the heat dissipation effect. In this way, the purpose of cooling and fire prevention is achieved. A dustproof net is provided at the air inlet to prevent dust from entering the inside of the device. After the device is powered on, the motor will start working, thereby driving the hollow gear to rotate. When the convex points on the hollow gear touch the convex points on the dustproof net, the dustproof net will be squeezed and move forward. After the bump leaves, the dust screen will be returned to its original position by the force of the spring. This back and forth movement causes the dust screen to vibrate, thereby achieving the effect of dust removal. In this way, the purpose of cooling and fire prevention is achieved. When the circuit breaker trips due to excessive current, the motor will lose power supply due to tripping and stop working, thereby driving the fan to stop working. After the fan stops working, no airflow is generated, causing the movable baffle to return to its original position. After the movable baffle returns to its original position, a closed environment is formed inside the short-circuit breaker, and air no longer circulates. If an electric spark generates a flame, it will consume the oxygen inside the equipment, reducing the oxygen content, causing the flame to no longer burn. In this way, the purpose of cooling and fire prevention is achieved.

[0004] Although this structure can cool down the circuit breaker to prevent fire, when the circuit breaker catches fire, it extinguishes the fire by isolating oxygen, and the circuit breaker will continue to burn until the oxygen is consumed. This method is dangerous. Therefore, we propose a circuit breaker device with fire prevention function that can extinguish the fire of the burning circuit breaker in time to avoid the danger caused by continued burning, so as to improve the fire prevention effect. Summary of the invention

[0005] The object of the present invention is to provide a circuit breaker device with a fire protection function to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the present invention provides the following technical solutions: a circuit breaker device with a fire prevention function, comprising a circuit breaker body, a switch is hingedly connected to the outer wall of the circuit breaker body, an electronic component is arranged inside the circuit breaker body, a circuit breaker element is arranged below the electronic component, an opening and closing heat dissipation mechanism is arranged inside the circuit breaker body, a fire prevention box is arranged outside the circuit breaker body, and a processing component is arranged outside the electronic component, the processing component includes a fire extinguishing component arranged outside the electronic component, an isolation component is arranged outside the fire extinguishing component, and a disassembly component is arranged outside the isolation component.

[0008] According to the above technical solution, the isolation assembly includes a frame fixedly installed inside the fireproof box, a first magnetic strip is fixedly installed on the inner wall of the frame, a support plate is hingedly connected inside the frame, a second magnetic strip is fixedly installed on the outer wall of the support plate, a pressure rod is slidably arranged inside the first magnetic strip, a pressure plate is fixedly installed on the end of the pressure rod, a closing plate is hingedly connected to the inner wall of the fireproof box, a sliding rod is fixedly installed on the outer wall of the circuit breaker body, and a third bracket is slidably arranged on the outer wall of the sliding rod.

[0009] According to the above technical solution, the disassembly and assembly component includes a fixed block fixedly installed on the outer wall of the fireproof box, a limiting groove is provided on the outer wall of the fixed block, a limiting block is slidably arranged inside the limiting groove, a hook is fixedly installed on the outer wall of the limiting block, a limiting rod is fixedly installed on the outer wall of the hook, a fourth bracket is slidably arranged on the outer wall of the limiting rod, a spring is provided on the side of the hook away from the limiting rod, a mounting plate is clamped on the outer wall of the spring, and a slot is provided on the outer wall of the mounting plate.

[0010] According to the above technical solution, the outer wall of the baffle is set in an inclined surface, the outer wall of the dispersion plate is set in an inclined surface, and the end of the dispersion plate is fixedly installed on the inner wall of the material holding frame. Under the restriction of the dispersion plate and the baffle set in the inclined surface, the fire extinguishing powder inside the material holding frame can be discharged, and the fire extinguishing powder can be evenly covered on the electronic components and the circuit breaker components to perform fire extinguishing work. The float is made of an easily fusible material, and the float floats inside the water holding frame. Under the restriction of the float made of an easily fusible material, when the internal temperature of the burning circuit breaker body is high, the float will melt. At this time, the float is not affected by the buoyancy, and it drives the push rod, the pull frame and the baffle to move downward, so that the baffle discharges the fire extinguishing powder inside the material holding frame to cover the flames and extinguish the fire.

[0011] According to the above technical solution, the outer wall of the sealing ring is slidably arranged inside the sleeve, and the elastic plate is made of elastic material. Under the sealing sliding restriction of the sealing ring and the sleeve, the air inside the circuit breaker body can be sucked into the sleeve through the suction disk. When the suction is completed, the elastic plate is not pushed by the gas. Under the elastic action of the elastic plate, it resets and is in a closed state, preventing the gas inside the sleeve from flowing out, so as to achieve a flame retardant effect.

[0012] According to the above technical solution, the second magnetic strip is magnetically attracted to the first magnetic strip, and the closing plate is arranged at an angle. When the switch trips, it pushes the pressure plate to make the pressure rod squeeze the support plate with a force greater than the magnetic attraction force between the second magnetic strip and the first magnetic strip, so that the support plate rotates toward the inside of the fireproof box, and the circuit breaker body slides toward the inside of the fireproof box. Under the action of gravity of the closing plate, it rotates toward the top of the circuit breaker body and covers the top of the fireproof box, so that the inside of the fireproof box is sealed.

[0013] According to the above technical solution, the end of the hook is arranged in an inclined surface, and the hook and the slot are adapted to be engaged. Under the restriction of the hook arranged in the inclined surface, the hook and the slot can be quickly engaged and installed.

[0014] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The circuit breaker device with fire prevention function of the present invention is composed of a fire extinguishing assembly as one of its components. When the circuit breaker body is used and a fire occurs, the internal temperature of the circuit breaker body is relatively high. Since the float is made of an easily fusible material, the float melts under the high temperature limit. At this time, the float is not pushed by the buoyancy, and it drives the push rod to slide inside the water holding frame. Under the action of the push rod and the gravity of the pull frame, the baffle fixedly installed at the end of the pull frame is driven to move downward. The baffle is no longer sealed with the dispersion plate, and the fire extinguishing powder inside the material holding frame falls downward, and the fire extinguishing powder covers the electronic components and the circuit breaker components to cover and extinguish the fire source to prevent the fire from continuing. When the circuit breaker When the device body is in normal use, under the restriction of the opening and closing heat dissipation mechanism, the inside of the circuit breaker body can be cooled down to prevent the floating ball from melting due to the high temperature inside the circuit breaker body. When the floating ball is in an expanded state, under the buoyancy of the water inside the water holding frame, it pushes the floating ball upward, so that the push rod drives the pull frame upward, and the pull frame drives the baffle to contact and seal with the dispersion plate to prevent the leakage of fire extinguishing powder inside the material holding frame. When the material holding frame catches fire, the opening and closing heat dissipation mechanism is powered off, and the opening and closing heat dissipation mechanism is closed at the same time to prevent external oxygen from entering the inside of the circuit breaker body. This structure can cover the fire source bracket with fire extinguishing powder to isolate oxygen and prevent the fire from continuing to burn.

[0015] 2. The circuit breaker device with fire prevention function of the present invention is composed of a fire extinguishing component as one of its components. When the float melts, it drives the push rod and the pull frame to move downward, and the U-shaped rod fixedly installed at the bottom of the connecting plate fixedly installed on the outer wall of the pull frame moves downward accordingly. The sealing ring fixedly installed at the end of the U-shaped rod slides inside the sleeve. Since the sealing ring slides with the sleeve seal, under its restriction, the sealing ring draws the air of the suction disk connected to the end of the sleeve. When the sleeve inhales air, the elastic plate hingedly connected to the side wall of the fixed ring fixedly installed on the inner wall of the sleeve rotates. When the sealing ring no longer slides, it is reset and closed under the elastic action of the elastic plate to prevent the gas inside the sleeve from flowing out. This structure can draw the gas inside the circuit breaker body and reduce the oxygen content inside the circuit breaker body to achieve a flame retardant effect.

[0016] 3. The circuit breaker device with fire prevention function of the present invention is composed of an isolation component as one of its components. When the circuit breaker body catches fire, it needs to be stored in the fireproof box to isolate oxygen and prevent the fire from spreading. When the circuit breaker body is overloaded, the switch is powered off and tripped. The outer wall of the switch presses the outer wall of the pressure plate, so that the pressure plate presses the top surface of the support plate through the pressure rod, so that the support plate deflects downward. At this time, the second magnetic strip is no longer magnetically attracted to the first magnetic strip, and the support plate no longer supports the bottom of the circuit breaker body. Under the gravity of the circuit breaker body, the sliding rod fixedly installed on its outer wall slides inside the third bracket fixedly installed on the inner wall of the fireproof box, so that the circuit breaker body slides as a whole into the fireproof box. Since the closing plate is tilted and placed on the outer wall of the circuit breaker body, when the circuit breaker body slides into the fireproof box, the closing plate is closed in opposite directions under the action of gravity to cover the top of the fireproof box. At this time, a sealed space is formed inside the fireproof box to isolate the burning circuit breaker body from the outside world and prevent the fire from spreading.

[0017] 4. The circuit breaker device with fire prevention function of the present invention is composed of a disassembly and assembly component as one part. When the circuit breaker body needs to be used, it needs to be quickly installed, the hook is aligned with the slot opened on the outer wall of the mounting plate, the inclined surface of the hook is in contact and squeezed with the inner wall of the mounting plate, and the spring inside the hook is compressed. When the hook is engaged with the slot, the spring is not squeezed at this time. Under its elastic action, it pushes the hook toward each other to engage the hook with the mounting plate, so that the fireproof box can be quickly installed on the outer wall of the mounting plate. When the fireproof box needs to be disassembled, the limit rod is pressed to make the limit rod drive the hook to move, so that the limit block fixedly installed on the outer wall of the hook slides inside the limit slot opened on the outer wall of the fixed block, so that the hook is no longer engaged with the slot, so that the fireproof box can be quickly disassembled as a whole.

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only 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. Example 1

[0020] A preferred embodiment of a circuit breaker device with fire protection function provided by the present invention is as follows: Figures 1 to 9 As shown: a circuit breaker device with fire protection function, comprising a circuit breaker body 1; A switch 2 is hingedly connected to the outer wall of the circuit breaker body 1; An electronic component 3 is arranged inside the circuit breaker body 1; A circuit breaker element 5 is provided below the electronic element 3; An opening and closing heat dissipation mechanism 6 is provided inside the circuit breaker body 1; A fireproof box 7 is provided outside the circuit breaker body 1; and a processing assembly 4 arranged outside the electronic component 3, the processing assembly 4 includes a fire extinguishing assembly 41 arranged outside the electronic component 3, the fire extinguishing assembly 41 includes a material holding frame 411 fixedly installed inside the circuit breaker body 1, a dispersion plate 412 is fixedly installed inside the material holding frame 411, a baffle 413 is slidably arranged inside the dispersion plate 412, a pull frame 414 is fixedly installed at the bottom of the baffle 413, a push rod 415 is fixedly installed on the side of the pull frame 414 away from the baffle 413, a float 416 is fixedly installed on the end of the push rod 415 away from the pull frame 414, and a water holding container is arranged outside the float 416 Frame 417, a first bracket 418 is fixedly installed on the outer wall of the water holding frame 417, a second bracket 419 is fixedly installed on the inner wall of the circuit breaker body 1, a sleeve 420 is connected to the inside of the second bracket 419, a fixing ring 421 is fixedly installed on the inner wall of the sleeve 420, an elastic plate 422 is hingedly connected to the side wall of the fixing ring 421, a suction disc 423 is connected to the end of the sleeve 420, a U-shaped rod 424 is slidably arranged inside the sleeve 420, a sealing ring 425 is fixedly installed on the end of the U-shaped rod 424, and a connecting plate 426 is fixedly installed on the end of the U-shaped rod 424 away from the sealing ring 425.

[0021] In this embodiment, when the circuit breaker body 1 is used and a fire occurs, the internal temperature of the circuit breaker body 1 is relatively high. Since the float 416 is made of an easily fusible material, the float 416 melts under the high temperature limit. At this time, the float 416 is not pushed by the buoyancy, and it drives the push rod 415 to slide inside the water holding frame 417. Under the gravity of the push rod 415 and the pull frame 414, the baffle 413 fixedly installed at the end of the pull frame 414 moves downward, and the baffle 413 is no longer sealed with the dispersion plate 412. The fire extinguishing powder inside the material holding frame 411 falls downward, and the fire extinguishing powder covers the electronic The components 3 and the circuit breaker components 5 are used to cover the fire source and extinguish the fire to prevent the fire from continuing. When the circuit breaker body 1 is used normally, under the restriction of the opening and closing heat dissipation mechanism 6, the temperature inside the circuit breaker body 1 can be reduced to prevent the floating ball 416 from melting due to the high temperature inside the circuit breaker body 1. When the floating ball 416 is in an expanded state, under the buoyancy of the water inside the water frame 417, it pushes the floating ball 416 upward, so that the push rod 415 drives the pull frame 414 upward, so that the pull frame 414 drives the baffle 413 to contact and seal with the dispersion plate 412, so as to prevent the fire extinguishing powder inside the material frame 411 from Leakage, when the material frame 411 is on fire, the opening and closing heat dissipation mechanism 6 is powered off, and at the same time the opening and closing heat dissipation mechanism 6 is closed to prevent external oxygen from entering the circuit breaker body 1. The structure can cover the fire source bracket with fire extinguishing powder to isolate oxygen and prevent the fire from continuing to burn. When the float 416 melts, it drives the push rod 415 and the pull frame 414 to move downward, and the U-shaped rod 424 fixedly installed at the bottom of the connecting plate 426 fixedly installed on the outer wall of the pull frame 414 moves downward accordingly, and the sealing ring 425 fixedly installed at the end of the U-shaped rod 424 slides inside the sleeve 420. The ring 425 slides in a sealed manner with the sleeve 420. Under its restriction, the sealing ring 425 draws air from the suction disk 423 connected to the end of the sleeve 420. When the sleeve 420 inhales air, the elastic plate 422 hingedly connected to the side wall of the fixed ring 421 fixedly installed on the inner wall of the sleeve 420 rotates. When the sealing ring 425 no longer slides, it is reset and closed under the elastic action of the elastic plate 422 to prevent the internal gas of the sleeve 420 from flowing out. This structure can draw the internal gas of the circuit breaker body 1 and reduce the oxygen content inside the circuit breaker body 1 to achieve a flame retardant effect. Example 2

[0022] A preferred embodiment of a circuit breaker device with fire protection function provided by the present invention is as follows: Figures 1 to 9As shown: the isolation component 43 includes a frame 431 fixedly installed inside the fireproof box 7, a first magnetic strip 432 is fixedly installed on the inner wall of the frame 431, a support plate 433 is hingedly connected inside the frame 431, a second magnetic strip 434 is fixedly installed on the outer wall of the support plate 433, a pressure rod 435 is slidably arranged inside the first magnetic strip 432, a pressure plate 436 is fixedly installed on the end of the pressure rod 435, a closing plate 437 is hingedly connected to the inner wall of the fireproof box 7, a sliding rod 439 is fixedly installed on the outer wall of the circuit breaker body 1, and a third bracket 438 is slidably arranged on the outer wall of the sliding rod 439.

[0023] In this embodiment, when the circuit breaker body 1 is on fire, it needs to be stored in the fireproof box 7 to isolate oxygen and prevent the fire from spreading. When the circuit breaker body 1 is overloaded, the switch 2 is powered off and tripped. The outer wall of the switch 2 presses the outer wall of the pressure plate 436, so that the pressure plate 436 presses the top surface of the support plate 433 through the pressure rod 435, so that the support plate 433 deflects downward. At this time, the second magnetic strip 434 is no longer magnetically attracted to the first magnetic strip 432, and the support plate 433 no longer supports the bottom of the circuit breaker body 1. Under the action of gravity, the slide bar 439 fixedly mounted on the outer wall thereof slides inside the third bracket 438 fixedly mounted on the inner wall of the fireproof box 7, so that the circuit breaker body 1 as a whole slides into the fireproof box 7. Since the closing plate 437 is tiltedly placed on the outer wall of the circuit breaker body 1, when the circuit breaker body 1 slides into the fireproof box 7, the closing plates 437 are closed oppositely under the action of gravity to cover the top of the fireproof box 7. At this time, a sealed space is formed inside the fireproof box 7, isolating the burning circuit breaker body 1 from the outside to prevent the fire from spreading. Example 3

[0024] A preferred embodiment of a circuit breaker device with fire protection function provided by the present invention is as follows: Figures 1 to 9 As shown: the disassembly and assembly component 44 includes a fixed block 441 fixedly installed on the outer wall of the fireproof box 7, a limiting groove 442 is provided on the outer wall of the fixed block 441, a limiting block 443 is slidably arranged inside the limiting groove 442, a hook 444 is fixedly installed on the outer wall of the limiting block 443, a limiting rod 445 is fixedly installed on the outer wall of the hook 444, a fourth bracket 446 is slidably arranged on the outer wall of the limiting rod 445, a spring 447 is provided on the side of the hook 444 away from the limiting rod 445, a mounting plate 448 is clamped on the outer wall of the spring 447, and a slot 449 is provided on the outer wall of the mounting plate 448.

[0025] When the circuit breaker body 1 needs to be used, it needs to be installed quickly. The hook 444 is aligned with the slot 449 opened on the outer wall of the mounting plate 448. The inclined surface of the hook 444 contacts and squeezes the inner wall of the mounting plate 448, and compresses the spring 447 on the inner side of the hook 444. When the hook 444 is engaged with the slot 449, the spring 447 is not squeezed. Under its elastic action, it pushes the hook 444 in the opposite direction, so that the hook 444 is engaged with the mounting plate 448, so that the fireproof box 7 can be quickly installed on the outer wall of the mounting plate 448. When the fireproof box 7 needs to be disassembled, the limit rod 445 is pressed, so that the limit rod 445 drives the hook 444 to move, so that the limit block 443 fixedly installed on the outer wall of the hook 444 slides inside the limit slot 442 opened on the outer wall of the fixing block 441, so that the hook 444 is no longer engaged with the slot 449, so that the fireproof box 7 can be quickly disassembled as a whole.

[0026] Among them, the outer wall of the baffle 413 is set in an inclined surface, the outer wall of the dispersion plate 412 is set in an inclined surface, and the end of the dispersion plate 412 is fixedly installed on the inner wall of the material holding frame 411. Under the restriction of the dispersion plate 412 and the baffle 413 set in the inclined surface, the fire extinguishing powder inside the material holding frame 411 can be discharged, and the fire extinguishing powder can be evenly covered on the electronic component 3 and the circuit breaker component 5 to perform fire extinguishing work. The float 416 is made of an easily fusible material, and the float 416 floats inside the water holding frame 417. Under the restriction of the float 416 made of an easily fusible material, when the internal temperature of the burning circuit breaker body 1 is high, the float 416 will melt. At this time, the float 416 is not affected by the buoyancy, and it drives the push rod 415, the pull frame 414 and the baffle 413 to move downward, so that the baffle 413 discharges the fire extinguishing powder inside the material holding frame 411 to cover the flame and extinguish the fire.

[0027] Among them, the outer wall of the sealing ring 425 is slidably arranged inside the sleeve 420, and the elastic plate 422 is made of elastic material. Under the sealing sliding restriction of the sealing ring 425 and the sleeve 420, the air inside the circuit breaker body 1 can be sucked into the sleeve 420 through the suction disk 423. When the suction is completed, the elastic plate 422 is not pushed by the gas. Under the elastic action of the elastic plate 422, it is reset and closed to prevent the internal gas of the sleeve 420 from flowing out, so as to achieve a flame retardant effect.

[0028] Among them, the second magnetic stripe 434 is magnetically attracted to the first magnetic stripe 432, and the closing plate 437 is set at an angle. When the switch 2 trips, it pushes the pressure plate 436 to make the pressure rod 435 squeeze the support plate 433 with a force greater than the magnetic attraction force between the second magnetic stripe 434 and the first magnetic stripe 432, so that the support plate 433 rotates toward the inside of the fireproof box 7, and the circuit breaker body 1 slides toward the inside of the fireproof box 7. Under the action of gravity of the closing plate 437, it rotates toward the top of the circuit breaker body 1 and covers the top of the fireproof box 7, so that the inside of the fireproof box 7 is sealed.

[0029] The end of the hook 444 is arranged at an inclined surface, and the hook 444 is adapted to be engaged with the slot 449 . Under the restriction of the hook 444 arranged at an inclined surface, the hook 444 and the slot 449 can be quickly engaged and installed.
