Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishers, and more particularly to an intelligent fire extinguisher. Background Art

[0002] A fire extinguisher is a portable fire-fighting tool. Chemical substances are placed inside the fire extinguisher to extinguish fires. Fire extinguishers are one of the common fire-fighting equipment and are stored in public places or where fires may occur. Different types of fire extinguishers are filled with different components and are designed for different causes of fires.

[0003] Currently, the size of handheld fire extinguishers is relatively small. Generally, the bottom is a cylinder, and a valve is installed at the top of the cylinder. A large amount of fire extinguishing medium (such as dry powder) is compressed by high-pressure gas inside the cylinder. When a fire breaks out in the environment it serves, after the alarm goes off, the on-duty personnel can come to get the fire extinguisher to extinguish the fire source.

[0004] In a closed room, the fire spreads rapidly. However, current fire extinguishers do not have an autonomous fire extinguishing function and cannot delay the spread of the fire in the first place, thus failing to buy precious fire-fighting time for firefighters.

[0031] The following further elaborates on the technical solution of the present invention in conjunction with the accompanying drawings of the specification and specific embodiments. Please refer to Figures 1 to 8 , an intelligent fire extinguisher provided by this application. Please pay particular attention to referring to Figures 1 to 5, including: a fire extinguisher body 100, the fire extinguisher body 100 includes a cylindrical cover 101, and a discharge pipe 102 provided at the top of the cylindrical cover 101. The top end of the discharge pipe 102 is provided with a hollow discharge disc 103, and a number of fire nozzles 104 are arranged in a circumferential array on the outer surface of the hollow discharge disc 103. A partition 105 is fixedly provided on the inner wall of the cylindrical cover 101, and a first sealing disc 106, a second sealing disc 107 and a third sealing disc 108 are slidably arranged in the cylindrical cover 101 from bottom to top in sequence. An expansion chamber 109 is formed between the first sealing disc 106 and the partition 105, a pressurizing chamber 1010 is formed between the second sealing disc 107 and the third sealing disc 108, and a fire extinguishing chamber 1011 is formed between the third sealing disc 108 and the top of the cylindrical cover 101. Carbon dioxide gas is filled in the expansion chamber 109, inert gas is filled in the pressurizing chamber 1010, and dry powder is filled in the fire extinguishing chamber 1011. First rubber rings 1012 and second rubber rings 1013 for respectively limiting the first sealing disc 106 and the third sealing disc 108 are fixedly provided on the inner wall of the cylindrical cover 101. There is a certain ventilation gap between the third sealing disc 108 and the inner wall of the cylindrical cover 101, so that after the third sealing disc 108 disengages from the second rubber ring 1013, the high-pressure inert gas in the pressurizing chamber 1010 can enter the interior of the fire extinguishing chamber 1011. Four mounting holes are circumferentially arrayed on the surface of the partition 105, and cylindrical heat-conducting metals 1014 are fixedly provided on the inner walls of the four mounting holes. The top ends of the cylindrical heat-conducting metals 1014 are fixedly provided with first springs 1015, and the top ends of the first springs 1015 are fixedly connected to the surface of the first sealing disc 106. An electric heating plate 1016 is fixedly provided on the inner bottom wall of the cylindrical cover 101. The fire extinguisher body 100 further includes a connection box 1017 threadedly connected to the bottom end of the cylindrical cover 101. A charging power supply 1018 and a PLC controller 1019 are respectively fixedly provided inside the connection box 1017, and a smoke sensor 1020 is fixedly provided at the bottom end of the connection box 1017. The smoke sensor 1020 and the electric heating plate 1016 are both electrically connected to the PLC controller 1019 through wires.

[0032] Specifically, by setting up the fire extinguisher body 100, during the actual use of the fire extinguisher, it can be placed in areas prone to fires. When a fire occurs, the smoke sensor 1020 receives the smoke. At this time, the smoke sensor 1020 transmits the signal to the PLC controller 1019, and the PLC controller 1019 automatically controls the electric heating plate 1016 to work. The heat generated by the electric heating plate 1016 is transmitted to the expansion chamber 109 through the cylindrical heat-conducting metal 1014 and the first spring 1015, heating the carbon dioxide gas in the expansion chamber 109. After the carbon dioxide gas is heated, it will rapidly expand, increasing the air pressure in the expansion chamber 109. When the air pressure increases to a certain level, the first sealing disk 106 will move upward out of the restraint of the first rubber ring 1012, and the first spring 1015 will be released from the restraint. Under the action of the air pressure, the first sealing disk 106 and the second sealing disk 107 will be quickly pushed upward, rapidly increasing the pressure of the inert gas in the pressurization chamber 1010, and pressurizing the third sealing disk 108 through the third spring 1025. When the third sealing disk 108 breaks free from the restraint of the second rubber ring 1013, it will drive the third sealing disk 108 to move upward rapidly. At the same time, the inert high-pressure gas in the pressurization chamber 1010 will enter the fire extinguishing chamber 1011, increasing the air pressure in the fire extinguishing chamber 1011 and driving the sealing plate 1022 to move upward. As a result, the dry powder mixed with high-pressure inert gas in the fire extinguishing chamber 1011 will enter the hollow discharge tray 103 and be quickly ejected through the fire nozzle 104, achieving the purpose of automatic fire extinguishing.

[0033] Among them, after the electric heating plate 1016 is heated, the process of pressurizing the dry powder is as follows: Heating - the expansion chamber 109 expands - the first sealing disk 106 breaks free from the first rubber ring 1012 (at this time, the first spring 1015 is released from the restraint) - the first sealing disk 106 and the second sealing disk 107 move upward, compressing and pressurizing the inert gas in the pressurization chamber 1010 (under the action of the elastic force of the first spring 1015 and the expansion of the gas in the expansion chamber 109) - the third sealing disk 108 breaks free from the restraint of the second rubber ring 1013 (after the pressure in the pressurization chamber 1010 reaches a certain level) - the high-pressure inert gas in the pressurization chamber 1010 enters the fire extinguishing chamber 1011 through the gap between the third sealing disk 108 and the edge of the cylindrical cover 101. At the same time, the third sealing disk 108 moves upward to squeeze the fire extinguishing chamber 1011, increasing the air pressure in the fire extinguishing chamber 1011 and driving the sealing plate 1022 to move upward. As a result, the dry powder mixed with high-pressure inert gas in the fire extinguishing chamber 1011 will enter the hollow discharge tray 103 and be quickly ejected through the fire nozzle 104.

[0034] Please refer specifically to Figure 4 and Figure 5, an installation disk 1021 is fixedly provided on the inner wall of the discharge pipe 102, and a discharge hole is formed on the upper surface of the installation disk 1021.

[0035] Specifically, it can achieve the purpose of protecting the dry powder inside the fire extinguishing chamber 1011 under the action of the second spring 1024 and the sealing plate 1022, and prevent external air and moisture from entering the fire extinguishing chamber 1011 when the fire extinguisher is idle.

[0041] Specifically, it can drive the cylindrical cover 101 to rotate automatically during the automatic fire extinguishing process of the fire extinguisher body 100, achieve the purpose of rotary fire extinguishing, and ensure the sufficiency of fire extinguishing.

[0042] Among them, by setting the support component 200, the present invention can stably place the fire extinguisher body 100 under the action of the support plate 201 and the support legs 202, and at the same time can lift the fire extinguisher body 100 for use. Moreover, when a fire occurs, when the PLC controller 1019 receives the signal from the smoke sensor 1020, the PLC controller 1019 also automatically controls the driving motor 203 to start. The rotation of the driving motor 203 drives the rotation of the driving gear disk 204, and the rotation of the driving gear disk 204 drives the rotation of the driven gear disk 205 and the cylindrical cover body 101, so as to achieve the purpose of automatically rotating the fire extinguisher body 100 for fire extinguishing, ensuring the sufficiency of the fire extinguishing range and improving the fire extinguishing effect.

[0043] Please refer specifically to Figure 4 and Figure 8 , a diffusion component 300 for diffusing the dry powder ejected from the fire extinguishing nozzle 104 is provided on the surface of the support plate 201.

A plurality of inclined upward high-pressure nozzles 303 are fixedly arranged on the outer surface of the annular pipe 302 in a circumferential array.

[0044] Specifically, under the action of the diffusion component 300, the dry powder ejected through the fire extinguishing nozzle 104 can be diffused obliquely upward, further increasing the fire extinguishing range.

A reciprocating lead screw 307 is rotatably arranged on the inner bottom wall of the arc-shaped box 301, and a threaded hole threadedly connected to the outer surface of the reciprocating lead screw 307 is opened on the upper surface of the sliding ring 304.

[0046] Specifically, the rotation of the reciprocating lead screw 307 drives the sliding ring 304 and the sealing ring 305 to move up and down reciprocally.

[0047] Please refer specifically to Figure 4 and Figure 7 , a connecting shaft 308 extending to the outer surface of the arc-shaped box 301 is rotatably arranged on the inner wall of the arc-shaped box 301, and a first bevel gear 309 meshing with each other is fixed on one end of the connecting shaft 308 and the outer surface of the reciprocating lead screw 307.

[0048] Specifically, under the action of the first bevel gear 309, the rotation of the connecting shaft 308 can drive the reciprocating lead screw 307 to rotate automatically. At the same time, under the action of the second bevel gear 3010 and the bevel gear ring 3011, the rotation of the cylindrical cover 101 can drive the connecting shaft 308 to rotate.

[0049] Please refer specifically to Figure 7 and Figure 8 An air charging pipe 3012 extending into the interior of the annular pipe 302 is embedded in the inner top wall of the arc-shaped box 301, and an air suction pipe 3013 extending to the outer surface of the arc-shaped box 301 is embedded in the top inner wall of the arc-shaped box 301. A filter cover is fixedly provided at the end of the air suction pipe 3013, and an air charging one-way valve and an air suction one-way valve are respectively arranged on the surfaces of the air charging pipe 3012 and the air suction pipe 3013.

[0050] Specifically, when the sealing ring 305 moves upward, the air inside the arc-shaped box 301 can be filled into the annular pipe 302 through the air charging pipe 3012, and when the sealing ring 305 moves downward, external air can be sucked into the arc-shaped box 301 through the air suction pipe 3013, so as to achieve the purpose of continuously jetting air through the high-pressure nozzle 303.

At the same time, when the sealing ring 305 moves downward, external air can be sucked into the arc-shaped box 301 through the air suction pipe 3013, so as to achieve the purpose of continuously jetting air through the high-pressure nozzle 303.

[0052] Working principle: During actual use, the fire extinguisher can be placed in areas prone to fires. When a fire occurs, the smoke sensor 1020 receives the smoke. At this time, the smoke sensor 1020 transmits the signal to the PLC controller 1019. The PLC controller 1019 automatically controls the electric heating plate 1016 to work. The heat generated by the electric heating plate 1016 is transmitted to the expansion chamber 109 through the cylindrical heat-conducting metal 1014 and the first spring 1015, heating the carbon dioxide gas in the expansion chamber 109. After the carbon dioxide gas is heated, it will expand rapidly, increasing the air pressure in the expansion chamber 109. When the air pressure increases to a certain extent, the first sealing disc 106 will move upward out of the restraint of the first rubber ring 1012. The first spring 1015 will be released from the restraint and, under the action of the air pressure, quickly push the first sealing disc 106 and the second sealing disc 107 upward, rapidly increasing the pressure of the inert gas in the pressurizing chamber 1010 and pressurizing the third sealing disc 108 through the third spring 2025. When the third sealing disc 108 breaks free from the restraint of the second rubber ring 1013, it will drive the third sealing disc 108 to move upward rapidly. At the same time, the inert high-pressure gas in the pressurizing chamber 1010 will enter the fire extinguishing chamber 1011, increasing the air pressure in the fire extinguishing chamber 1011 and driving the sealing plate 1022 to move upward, thereby driving the dry powder mixed with high-pressure inert gas in the fire extinguishing chamber 1011 into the hollow discharge tray 103 and quickly spraying it out through the fire nozzle 104 to achieve the purpose of automatic fire extinguishing; Moreover, during the occurrence of a fire, when the PLC controller 1019 receives the signal from the smoke sensor 1020, the PLC controller 1019 also automatically controls the driving motor 203 to start. The rotation of the driving motor 203 drives the driving gear disk 204 to rotate. The rotation of the driving gear disk 204 drives the driven gear disk 205 and the cylindrical cover 101 to rotate, thereby achieving the purpose of the automatic rotation and fire extinguishing of the fire extinguisher body 100, ensuring the sufficiency of the fire extinguishing range and improving the fire extinguishing effect; And during the process of the fire extinguisher body 100 achieving automatic rotation for fire extinguishing, the rotation of the cylindrical cover body 101 can drive the rotation of the bevel gear ring 3011. The rotation of the bevel gear ring 3011 drives the rotation of the second bevel gear 3010 and the connecting shaft 308. The rotation of the connecting shaft 308 drives the rotation of the reciprocating lead screw 307 under the action of the two first bevel gears 309. The rotation of the reciprocating lead screw 307 drives the sliding ring 304 to automatically move up and down reciprocally, thereby driving the sealing ring 305 to move up and down reciprocally through the connecting rod 306. When the sealing ring 305 moves upward, the air inside the arc-shaped box 301 can be filled into the annular pipe 302 through the air filling pipe 3012 and sprayed out to the range of the fire extinguishing nozzle 104 through the obliquely arranged high-pressure nozzle 303. Thus, the dry powder sprayed out from the fire extinguishing nozzle 104 can diffuse obliquely upward under the action of the high-pressure nozzle 303, further increasing the fire extinguishing range. At the same time, when the sealing ring 305 moves downward, it can suck external air into the arc-shaped box 301 through the air suction pipe 3013, thereby achieving the purpose of continuously jetting air through the high-pressure nozzle 303.

The above specific implementation manner is merely illustrative and not restrictive. Under the inspiration of this embodiment, those of ordinary skill in the art can also make many forms, all of which fall within the protection scope of this embodiment.
