DETAILED DESCRIPTION

[0076] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0077] like Figures 1 to 11 An intelligent circuit breaker based on Internet of Things control is shown, comprising:

[0078] A circuit breaker housing 1, wherein a first box body 2 and a second box body 23 are fixedly connected to both sides of the circuit breaker housing 1, and the interiors of the first box body 2 and the second box body 23 are filled with carbon tetrafluoride liquid;

[0079] A plurality of arc-extinguishing metal sheets 4 are arranged on the inner top of the circuit breaker housing 1;

[0080] A heat conduction channel flows from the second box body 23 to the first box body 2, and the channel runs through a plurality of arc-extinguishing metal sheets 4 to cool the arc-extinguishing metal sheets 4;

[0081] The heat conduction channel includes a metal tube 29 and an insulating tube 9. The insulating tube 9 is connected to the metal tube 29. The metal tube 29 passes through multiple arc-extinguishing metal sheets 4. The top center of the second box body 23 is connected to an insulating external tube. The end of the insulating external tube away from the second box body 23 is connected to the metal tube 29, and the connection point between the two is located at the end of the metal tube 29 away from the insulating tube 9. The end of the insulating tube 9 away from the metal tube 29 is connected to the first box body 2. A one-way valve is provided at the connection between the second box body 23 and the insulating external tube. The one-way valve can only allow the carbon tetrafluoride solution to flow into the insulating external tube.

[0082] The filling resin 6 is arranged between the second box body 23 and the circuit breaker housing 1, and the filling resin 6 penetrates the circuit breaker housing 1 and the wall plate of the second box body 23, so as to extinguish the fire of the circuit breaker housing 1;

[0083] An arc is generated in the circuit breaker housing 1 during the breaking process, and multiple arc-extinguishing metal sheets 4 are used to extinguish the arc. The temperature of the arc-extinguishing metal sheets 4 rises under the action of the arc, and the flow channel conducts the heat of the arc-extinguishing metal sheets 4 to the carbon tetrafluoride liquid in the first box body 2 and the second box body 23 to cool the arc-extinguishing metal sheets 4. After the arc-extinguishing metal sheets 4 cause the filling resin 6 to melt due to the heat generated by the arc, the carbon tetrafluoride liquid in the second box body 23 will flow to the inside of the circuit breaker housing 1 to extinguish the circuit breaker housing 1.

[0084] In a specific implementation, the circuit breaker housing 1 opens and closes the circuit according to the flow rate of the current. In the process of opening and closing the circuit, an electric arc often occurs. On the one hand, the electric arc increases the temperature of the arc-extinguishing metal sheet 4. On the other hand, if the current is too large, the outer wall of the circuit breaker housing 1 may melt, and then the circuit breaker housing 1 may burn out. By setting the heat conduction channel, when the temperature of the arc-extinguishing metal sheet 4 rises, part of the heat may be conducted through the metal tube 29 to the carbon tetrafluoride liquid inside the arc-extinguishing metal sheet 4, so that the temperature of the arc-extinguishing metal sheet 4 may be reduced to a certain extent.

[0085] When the instantaneous current inside the circuit breaker housing 1 is too large, its temperature will also rise rapidly, causing the circuit breaker housing 1 to catch fire and burn. Through the setting of the filling resin 6, when the temperature inside the circuit breaker housing 1 reaches the range of ignition, the high temperature will melt the filling resin 6, thereby forming a passage between the second box body 23 and the circuit breaker housing 1, so that the carbon tetrafluoride liquid in the second box body 23 flows to the inside of the circuit breaker housing 1 to extinguish the fire inside the circuit breaker housing 1. The carbon tetrafluoride liquid is easy to volatilize. Therefore, when a passage is formed between the second box body 23 and the circuit breaker housing 1, the carbon tetrafluoride liquid in the second box body 23 will expand after contacting with the air, and then form an airflow for spraying.

[0086] When the instantaneous current inside the circuit breaker housing 1 is too large, the temperature generated will also be conducted through the arc extinguishing metal sheet 4, and part of the temperature will be conducted into the carbon tetrafluoride liquid, thereby increasing the activity of the carbon tetrafluoride liquid. When the circuit breaker housing 1 burns out and catches fire, the spraying speed of the carbon tetrafluoride liquid can also be accelerated, thereby achieving the purpose of rapid fire extinguishing.

[0087] As a further embodiment of the present invention, it also includes:

[0088] The junction box 12 is embedded in the wall 10 and is used to install the circuit breaker housing 1. A card block is provided inside the junction box 12, and a buckle is fixedly connected to one side of the circuit breaker housing 1. The buckle is clamped on the card block. Figure 3 The circuit breaker housing 1 is fixed from a viewing angle, and a cover plate is provided at one end of the junction box 12.

[0089] The electromagnetic switch 31 is placed outdoors. After the current passes through the electromagnetic switch 31, it supplies power to the inside of the intelligent circuit breaker. The electromagnetic switch 31 is electrically connected to the circuit breaker housing 1 through the wire 30. The current flows from the electromagnetic switch 31 to the circuit breaker housing 1. It should be noted that the wire 30 used for circuit conduction is an electric wire.

[0090] When the circuit breaker housing 1 is damaged, the electromagnetic switch 31 is disconnected so that the resident can maintain a safe state without current during the process of replacing the intelligent circuit breaker.

[0091] In a specific implementation, the circuit breaker housing 1 is installed indoors, while the electromagnetic switch 31 is installed outdoors. During household electricity use, the circuit breaker housing 1 is used to ensure the safety of household electricity use. When the circuit breaker housing 1 is damaged, the electromagnetic switch 31 is disconnected so that there is no current when the household replaces the circuit breaker housing 1.

[0092] When the residents use electricity on a daily basis, the circuit inside the residence is controlled by the circuit breaker housing 1. For example, when replacing a light bulb, the indoor circuit is powered off by the circuit breaker housing 1. When the residents need to replace the circuit breaker housing 1, the electromagnetic switch 31 can be disconnected to ensure that the circuit breaker housing 1 can be replaced without electricity.

[0093] As a further embodiment of the present invention, it also includes:

[0094] The water pipe 13 has a sprinkler head 14 at its end. The water pipe 13 is pre-laid in the wall 10, and the sprinkler head 14 is fixed on the top wall of the room. The fixation of the sprinkler head 14 is a prior art and will not be disclosed in detail herein.

[0095] A flow rate sensor 33 is arranged inside the water pipe 13;

[0096] A controller 11, the controller 11 is used to control the electromagnetic switch 31 to be disconnected;

[0097] During a fire in a household's room, the water pipe 13 sprays water through the sprinkler head 14 to extinguish the fire, and the controller 11 controls the electromagnetic switch 31 to disconnect according to the flow rate information sensed by the flow rate sensor 33 to cut off the power supply to the circuit breaker housing 1.

[0098] In the specific implementation, in the prior art, a sprinkler system is usually installed in a residence. When a fire occurs, the sprinkler system automatically sprays water into the room. The sprinkler system is a prior art and will not be disclosed in detail here. The water pipe 13 and the sprinkler head 14 in the present invention are set as the application of the sprinkler system. When a fire occurs indoors, the water in the water pipe 13 will flow. Therefore, after the flow rate sensor 33 detects the flow of water, the electromagnetic switch 31 will be controlled to be disconnected through the controller 11 to avoid short circuit caused by burning the indoor wires due to fire, reducing the difficulty of subsequent maintenance, and also avoiding the short circuit of the indoor circuit caused by the failure of the circuit breaker housing 1 to be disconnected in the first time, providing an extra layer of protection for the indoor circuit.

[0099] As a further embodiment of the present invention, it also includes:

[0100] A breaking assembly is arranged in the circuit breaker housing 1, and is used to protect the circuit from overload. The breaking assembly includes a striker 3;

[0101] A rectangular slide 8 is slidably connected in the second box body 23, and a linear drive unit is provided at the bottom of the rectangular slide 8;

[0102] Output pipe 7, output pipe 7 is connected with the first box body 2, and output pipe 7 is located inside the circuit breaker housing 1; a pressure valve 24 is arranged inside one end of the output pipe 7 away from the first box body 2, and a pressure preset value is arranged inside the pressure valve 24. When the pressure inside the first box body 2 reaches the pressure preset value, the pressure valve 24 opens. This technology is prior art and will not be disclosed in detail here.

[0103] The controller 11 is also used to control the linear drive unit to push the rectangular slide 8 according to the flow rate information sensed by the flow rate sensor 33, so as to push the carbon tetrafluoride liquid in the second box body 23 into the first box body 2, and then the carbon tetrafluoride liquid is transported to the circuit breaker housing 1 through the output pipe 7 to impact the striker 3, so that the breaking assembly disconnects the circuit;

[0104] The linear drive unit includes two micro-electric cylinders 5, which are arranged on one side of the circuit breaker housing 1. The output end of the micro-electric cylinder 5 passes through the bottom wall plate of the second box body 23, and the output end of the micro-electric cylinder 5 is fixedly connected to the bottom of the rectangular slide 8;

[0105] In a specific implementation, when the sprinkler head 14 is performing water spraying to extinguish a fire, the flow rate sensor 33 controls the micro-electric cylinder 5 to extend through the controller 11, thereby causing the micro-electric cylinder 5 to squeeze the carbon tetrafluoride liquid in the second box body 23, causing it to flow into the first box body 2, so that the pressure in the first box body 2 is higher than the preset pressure value of the pressure valve 24, so that the carbon tetrafluoride liquid is sprayed into the inside of the circuit breaker housing 1 through the output pipe 7. On the one hand, it can perform fire prevention work on the circuit inside the circuit breaker housing 1, and on the other hand, it can also promote the disconnection of the breaking component, so that the indoor circuit is powered off to avoid the insulation layer of the indoor wires being burned by the flame and causing a short circuit.

[0106] If the filling resin 6 melts during this process, the carbon tetrafluoride liquid in the second box body 23 will enter the circuit breaker housing 1 through the channel where the filling resin 6 is located. The carbon tetrafluoride liquid is filled into the interior of the circuit breaker housing 1 to achieve the purpose of fire prevention work on the interior of the circuit breaker housing 1. As the micro-electric cylinder 5 extends, when the rectangular slide 8 rises to above the channel where the filling resin 6 is located, the rectangular slide 8 will squeeze the gas inside the second box body 23, so that the gas inside the second box body 23 enters the first box body 2, driving the pressure in the first box body 2 to increase, thereby achieving the purpose of opening the pressure valve 24.

[0107] As a further embodiment of the present invention, the breaking assembly further comprises:

[0108] The coil 27 is arranged inside the circuit breaker housing 1; the striker 3 is slidably connected to the inner side of the coil 27, and the end of the output tube 7 away from the first box body 2 extends to the top of the striker 3;

[0109] A return spring 28 is used to push the striker 3 to return to its original position;

[0110] It should be noted that a dial plate 25 is also provided inside the circuit breaker housing 1, and the dial plate 25 is rotatably connected inside the circuit breaker housing 1, and the striker 3 is used to strike the dial plate 25, and one end of the dial plate 25 is transmission-connected to a circuit breaker switch, and the short circuit breaker switch is rotatably connected to one side of the circuit breaker housing 1, and a paddle 26 is provided below the end of the dial plate 25 away from the circuit breaker switch, and the paddle 26 is used to connect the circuit, and its current flows into the coil 27 through the wire, and then flows into the fixed contact (the contact of the circuit breaker in the prior art) through the coil 27, and the paddle 26 is in active contact with the contact, and the bottom of the end of the paddle 26 away from the dial plate 25 is connected with a connecting wire, and the connecting wire is used to connect the terminal of the output end of the circuit breaker housing 1, and the input end of the coil 27 is used to connect the terminal of the input end of the circuit breaker housing 1. The above descriptions are all prior art, and there are also related structures for driving it to disconnect, because they are all prior art, no more details are given here.

[0111] By utilizing the principle of electromagnetic induction, when a current overload occurs in the circuit, the magnetic force exerted by the coil 27 on the striker 3 through electromagnetic induction will increase, and the magnetic force will be utilized to displace the striker 3 to disconnect the circuit; when a fire occurs indoors, the output tube 7 will spray carbon tetrafluoride liquid, and the liquid sprayed from the output tube 7 will impact the striker 3 to drive the striker 3 to disconnect the circuit.

[0112] In a specific implementation, when the circuit is disconnected, the paddle 26 is separated from the contact, and when the circuit is connected, the paddle 26 abuts against the contact. During the contact or separation between the paddle 26 and the contact, an arc is generated. If the arc is not handled in time, electric sparks are generated.

[0113] As a further embodiment of the present invention, it also includes:

[0114] A connecting pipe 17 is connected to one side of the water pipe 13 to guide part of the water flow in the water pipe 13 out;

[0115] An embedded box body 16 is embedded in the wall body 10 and is located below the junction box 12. A plurality of nozzles 15 are disposed on the embedded box body 16.

[0116] A connecting flow channel, the two ends of which connect the connecting pipe 17 with the plurality of nozzles 15;

[0117] The connecting flow channel includes a driving box body 18 fixedly connected to the top center of the embedded box body 16, a rectangular slide is arranged inside the driving box body 18, a connecting groove 34 is opened at the bottom center of the rectangular slide, the connecting groove 34 is connected to the collecting groove 32, the collecting groove 32 is opened in the embedded box body 16, and the collecting groove 32 is connected to multiple nozzles 15.

[0118] The solenoid valve 21 is arranged at one end of the connecting pipe 17 away from the water pipe 13;

[0119] The controller 11 is also used to control the solenoid valve 21 to open;

[0120] During a fire in a household, the controller 11 controls the solenoid valve 21 to open, so as to guide part of the water flow in the water pipe 13 to the sprinkler 15 , thereby causing the sprinkler 15 to spray water to protect the junction box 12 .

[0121] In a specific implementation, when a fire occurs indoors in a resident's home, the flow rate sensor 33 controls the solenoid valve 21 to open through the controller 11, directing part of the water flow in the water pipe 13 to the nozzle 15, and then spraying the water in front of the wall 10 through the nozzle 15, so as to prevent the fire from spreading to the location of the junction box 12, so as to protect the circuit breaker housing 1 in the junction box 12.

[0122] As a further embodiment of the present invention, it also includes:

[0123] The alarm 22 is used to sound an alarm when a fire occurs indoors; the alarm 22 is fixedly connected to the wall 10 .

[0127] In a specific implementation, after the solenoid valve 21 is opened, part of the water flow in the water pipe 13 will enter the rectangular slideway inside the drive box 18. During this process, the water flow will squeeze the slider 19 so that the slider 19 moves toward the direction close to the contact switch 20. After the slider 19 abuts against the contact switch 20, the contact switch 20 will feedback a trigger information to the controller 11. The controller 11 controls the alarm 22 to turn on according to the trigger information, so that the alarm 22 sounds an alarm to remind the residents to extinguish the fire in time. When the slider 19 moves to the side of the connecting groove 34 away from the water pipe 13, the water pipe 13 is connected to the nozzle 15.

[0128] When the water pressure in the water pipe 13 is sufficient, the slider 19 can be removed as another embodiment of the present invention, and the high pressure of the water flow can impact the contact switch 20 so that the contact switch 20 turns on the alarm 22.

[0129] As a further embodiment of the present invention, a control method of an intelligent circuit breaker based on Internet of Things control comprises the following steps:

[0130] The controller 11 generates first control information and second control information according to the flow rate information sensed by the flow rate sensor 33;

[0131] The controller 11 sends the first control information to the electromagnetic switch 31, so that the controller 11 controls the electromagnetic switch 31 to be disconnected according to the flow rate information sensed by the flow rate sensor 33, so as to cut off the power supply to the circuit breaker housing 1;

[0132] The controller 11 sends the second control information to the linear drive unit to control the linear drive unit to push the rectangular slide 8 according to the flow rate information sensed by the flow rate sensor 33, so as to push the carbon tetrafluoride liquid in the second box body 23 into the first box body 2, and then the carbon tetrafluoride liquid is transported to the circuit breaker housing 1 through the output pipe 7 to impact the striker 3, so that the breaking component disconnects the circuit.

[0133] As a further embodiment of the present invention, the working method of the flow velocity sensor 33 during the flow of water in the water pipe 13 is specifically as follows:

[0134] The flow rate sensor 33 obtains the flow rate information in the water pipe 13;

[0135] The flow rate sensor 33 generates first request information according to the flow rate information;

[0136] The flow rate sensor 33 sends the first request information to the controller 11 to request the controller 11 to control the electromagnetic switch 31 to disconnect, so as to cut off the power supply to the circuit breaker housing 1, and control the linear drive unit to push the rectangular slide 8 to push the carbon tetrafluoride liquid in the second box body 23 into the first box body 2, and then the carbon tetrafluoride liquid is transported to the circuit breaker housing 1 through the output pipe 7 to impact the striker 3, so that the breaking component disconnects the circuit;

[0137] The basis for generating the first request information is that when the flow rate of water in the water pipe 13 exceeds one hundred milliliters per second, the flow rate sensor 33 generates the first request information.

[0138] As a further embodiment of the present invention, the working method of the controller 11 controlling the alarm 22 to sound an alarm is specifically as follows:

[0139] An alarm 22, used to sound an alarm when a fire occurs in a resident's room;

[0140] A trigger component, which is disposed in the communicating flow channel and is used to control the alarm 22 to sound an alarm;

[0141] The controller 11 is also used to control the alarm 22 to sound an alarm according to the trigger information of the trigger component;

[0142] The control method also includes the following steps:

[0143] The controller 11 generates third control information according to the trigger information generated by the trigger component under the action of the water flow;

[0144] The controller 11 sends the third control information to control the alarm 22 to sound an alarm.

[0145] Working principle of the present invention:

[0146] By setting the second box body 23 and the filling resin 6, the fire inside the circuit breaker housing 1 can be extinguished, which is beneficial to avoid the excessive heat generated by the arc due to the excessive forward current in the circuit breaker housing 1, which in turn causes the fire inside the circuit breaker housing 1, thereby achieving the purpose of protecting the inside of the circuit breaker housing 1. When the forward current fails to reach the fire range, part of the heat can be transferred to the carbon tetrafluoride liquid inside the first box body 2 and the second box body 23 through the metal tube 29 for heat dissipation, which is beneficial to avoid the outer shell of the circuit breaker housing 1 from melting due to excessive heat; when the circuit breaker housing 1 continuously generates an arc, the temperature inside it will rise in stages, which will cause the circuit breaker housing 1 to burn out. When the arc is continuously generated inside the circuit breaker housing 1, the arc extinguishing metal sheet 4 can be cooled by heat conduction, which avoids the circuit breaker housing 1 from burning out due to the continuous increase in temperature that cannot be dissipated.

[0147] By setting the electromagnetic switch 31 and the flow rate sensor 33, it is possible to effectively cut off the power supply to the indoor circuit in case of a fire indoors, so as to avoid a short circuit caused by burning the insulation layer of the wires in the indoor circuit, thereby preventing the fire from being aggravated by the short circuit, improving the safety of the indoor fire, and protecting the circuit breaker housing 1 in case of a fire outside. When a fire occurs indoors, the nozzle 15 is set to prevent the fire from spreading to the junction box 12 where the circuit breaker housing 1 is located, thereby protecting the junction box 12.

[0148] Secondly, when a fire occurs, the micro-electric cylinder 5 can be used to squeeze the carbon tetrafluoride liquid into the first box body 2, and then sprayed into the interior of the circuit breaker housing 1 through the output tube 7. After leaving the first box body 2, the carbon tetrafluoride liquid will enter the output tube 7 and then sprayed on the striker 3. The kinetic energy contained in the carbon tetrafluoride liquid is used to make the striker 3 descend, and then the striker 3 hits the paddle 25, and the auxiliary striker 3 promotes the descending of the paddle 25, so that the paddle 26 is separated from the contact, ensuring that the circuit is disconnected.

[0149] As a further embodiment of the present invention, in a specific implementation, a shell can be added outside the circuit breaker housing 1 of the present invention, and the shell wraps the first box body 2 and the second box body 23, and its appearance is as follows: Fig.12 As shown, it is used to be installed in the junction box 12 and adapted to the existing household circuit breaker so that the contact surfaces thereof overlap.

[0150] 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 to the above embodiments, and the above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements fall within the scope of the present invention claimed.
