Description
Technical Field
[0001] The utility model relates to the technical field of fire extinguisher equipment, in particular to a novel fire extinguishing device. Background Art
[0002] When extinguishing a fire, a foam fire extinguisher sprays a large amount of carbon dioxide and foam. The extinguishing medium adheres to the combustible material, isolating it from the air and extinguishing the fire. Foam fire extinguishers are mainly divided into portable foam fire extinguishers and cart-type foam fire extinguishers.
[0003] While existing foam fire extinguishers meet this need to a certain extent, they are limited by their structure and cannot achieve timely fire extinguishing. For example, when a fire occurs in equipment within a building, personnel cannot immediately detect and extinguish the fire, which can lead to the escalation of the fire accident. Although existing technologies also install fire alarms and detect fires at relevant locations, after a fire is detected, wireless prompt signals (including text messages, etc.) are sent to personnel who are not on site. However, it takes a certain amount of time for the personnel to arrive at the scene, so the fire cannot be extinguished in time, and the fire accident can be escalated. In summary, it is particularly necessary to provide a fire extinguishing device that can achieve timely fire extinguishing. Utility Model Content

Figure 3 、 4Among them, relays K1, K2, K3, and K4 are DC12V relays; the resistance of resistor R1 is 4.7K; the SMS module D5 is a mobile phone SMS alarm module finished product of brand Juying and model g7rV97Jk, which has two power input terminals and six low-level signal input terminals. After the six low-level signal input terminals input low-level signals respectively, it will send six SMS messages in the memory (this model has a pre-stored SMS message with the content "On-site fire"); the thyristor VS is a plastic-encapsulated single-phase thyristor model MCR100-1; the battery G1 is a 12V / 10Ah lithium battery; The power module T is a finished product of an AC 220V to DC 12V switching power supply module; the motor reduction mechanism M is a finished product of a 100W motor gear reducer with a rotating shaft of 10 revolutions per minute; the electric push rod M1 is a finished product of a 50W reciprocating electric telescopic rod; the electric push rod M2 is a finished product of a 5W reciprocating small pen-style electric telescopic rod (the upper and lower ends of the cylinders of the electric push rods M1 and M2 respectively have limit switches. When the push rods of the electric push rods M1 and M2 move up or down to the stop point, the motors of the electric push rods M1 and M2 will lose power. The motors will only be energized when the reverse power input is input); the fire detection module T 1 is a finished smoke alarm of model JTY-GD-CA2001L, which has two power input terminals and one power output terminal. When it detects smoke from a fire, the power output terminal outputs power, otherwise it does not output power. The solenoid valve DC is a normally closed valve core 1W solenoid valve. The wireless camera SX is a 4G wireless camera of model QS22AQ-4G03, which can transmit the collected images wirelessly via the 4G network. The wireless receiving display XS is a finished LCD wireless receiving display of model TH981H (the wireless receiving display XS, wireless camera SX and existing drones are equipped with wireless The structure and working principle of the wireless camera and wireless receiving display are the same); the mobile phone remote control module T3 is a remote wireless mobile phone remote control module model CL4-GPRS. This control module has two power input terminals 1 and 2, four control power output terminals, and an operating voltage of DC 12V. During operation, through the existing mature mobile phone APP technology, the staff can send control commands remotely through the mobile phone APP via the wireless mobile network. After receiving the control commands, the remote wireless mobile phone remote control module T3 will control the four control power output terminals to output or not output power.
[0017] Figure 1 、 2As shown in Figures 3 and 4, turning on power switch S2 energizes the wireless receiving display screen XS. A 220V AC power supply enters pins 1 and 2 of the power module T, and pins 3 and 4 then output a stable 12V DC power supply to the power input of the camera SX and the fire detection circuit 5. When the fire detection circuit is energized and operational, if there is no fire at the scene, pin 3 of the fire detection module T1 will not output a high-level signal, relay K1 will not energize, and the circuits and modules powered by relay K1 will not energize. If a fire occurs at the scene, pin 3 of the fire detection module T1 outputs a high-level signal, which is reduced and limited by resistor R1 and then fed into the control gate of the thyristor VS. This triggers the thyristor VS to conduct, energizing relay K1 and closing its control power input and normally open contacts. This in turn energizes the wireless camera SX (the live video signal transmitted by the wireless camera SX is wirelessly transmitted to the wireless receiving display screen XS, providing real-time images of the fire scene to management personnel), SMS module T2, and the control circuit. When SMS module T2 is energized, its pins 2 and 3 are connected, so it sends a stored text message. Upon receiving the message, the relevant remote administrator's mobile phone is immediately informed of the fire. Then, by observing the video data received by the nearby wireless receiving display XS, they can control the operation of the fire extinguisher body 1 through their mobile phone. After the administrator sends a fourth wireless closing signal via the mobile phone application interface, the mobile phone remote control module T3 receives it, and its pin 6 outputs a high level, which enters the positive power input of the solenoid valve DC and relay K4. The solenoid valve DC is energized, and relay K4 is energized, closing its control power input and normally open contact terminals. Furthermore, the positive and negative power input terminals of the electric push rod M2 are energized, and its push rod drives the movable handle 104 of the fire extinguisher body 1 downward. As the movable handle 104 descends, the fire extinguishing agent inside the fire extinguisher body 1 is discharged through the valve core of the opened solenoid valve DC and the fire extinguishing agent pipe 102, extinguishing the fire. After the fire is extinguished, the manager sends the fourth wireless open-circuit signal through the mobile phone application interface. After the mobile phone remote control module T3 receives it, its 6th pin stops outputting a high level, the solenoid valve DC loses power and the valve core is closed. After the relay K4 loses power and no longer attracts, its control power input end and the normally open contact end are open, and the positive and negative power input ends of the electric push rod M2 will lose power (specifically, when the push column of the electric push rod M2 drives the movable handle downward to the stop point, the electric push rod M2 will lose power, and the electric push rod M2 will only be energized if the reverse input power is input).
[0018] Figure 1 、 2As shown in Figures 3 and 4, the administrator sends a first wireless closing signal via the mobile phone application interface as needed. After receiving the signal, the mobile phone remote control module T3 outputs a high level at pin 3, which then feeds the positive power input of the motor reduction mechanism M (the wire connected to the motor reduction mechanism M enters the cylinder through the lower left end of the cylinder). The motor reduction mechanism M is energized, and its shaft drives the fire extinguisher body 1 and other components to rotate (the wire connected to the motor reduction mechanism has a length margin to prevent the wire from being straightened or broken when the fire extinguisher body 1 rotates). When the front end of the fire extinguishing agent tube 102 is aligned with the fire point, the administrator sends a first wireless opening signal via the mobile phone application interface. After receiving the signal, the mobile phone remote control module T3 stops outputting a high level at pin 3, which then feeds the positive power input of the motor reduction mechanism M. The shaft of the motor reduction mechanism M no longer drives the fire extinguisher body 1 and other components to rotate, and the front end of the fire extinguishing agent tube 102 is fixedly aligned with the fire point, extinguishing the fire. Specifically, after the management personnel sends the second or third wireless closing signal through the mobile phone application interface as needed, after the mobile phone remote control module T3 receives it, its 4th or 5th pin outputs a high level and enters the positive power input terminal of the relay K2 or K3. The relay K2 or K3 is energized and its control power input terminal and the normally open contact terminal are closed. In this way, the positive and negative or negative and positive power input terminals of the electric push rod M1 are energized; after the positive and negative power input terminals of the electric push rod M1 are energized, its push column drives the fire extinguisher body to move upward, and after the negative and positive power input terminals of the electric push rod M1 are energized, its push column drives the fire extinguisher body to move downward, and the front end of the fire extinguishing agent tube 102 will be aimed upward or downward at the fire point to extinguish the fire. The management personnel sends the second or third wireless closed-circuit open signal through the mobile phone application interface as needed. After the mobile phone remote control module T3 receives the signal, its 4th or 5th pin stops outputting a high level and enters the positive power input terminal of the relay K2 or K3. When the relay K2 or K3 loses power, it no longer attracts its control power input terminal and the normally open contact terminal opens. In this way, the positive and negative or negative and positive power input terminals of the electric push rod M1 lose power. After the front end of the fire extinguishing agent pipe 102 is in place upward or downward, it is aimed at the fire point to extinguish the fire.
[0019] Figure 1 、 2 As shown in Figures 3 and 4, through the above, the present invention can immediately notify the relevant remote management personnel through text messages after a fire occurs. The management personnel can control the push column of the second electric push rod through the control circuit in real time to drive the movable handle of the foam fire extinguisher body downward, and then the nozzle of the fire extinguisher body can spray fire extinguishing agent to extinguish the fire. During the fire extinguishing, the management personnel can also control the height and angle of the fire extinguisher body so that the front end of the nozzle can be aimed at the fire point as much as possible, thereby achieving a timely and better fire extinguishing effect.
