When a fire occurs, the electric signal required for fire extinguishing in the fire is not required to be sent to the fire extinguishing device through an electric signal transmission device such as a cable, the gas in the gas storage tank 162 is discharged through the pressure relief device 200, so that the gas pressure in the gas storage tank 162 is reduced, and when the gas pressure in the gas storage tank 162 is reduced to be smaller than the closing pressure of the one-way pneumatic angle seat valve 161, the first water pipe 130 can be opened through the one-way pneumatic angle seat valve 161, so that water entering the water inlet pipe 110 can be conveyed to the water outlet pipe 120 through the first water pipe 130, and the water can be conveyed to the position where the fire occurs through the water outlet pipe 120 for fire extinguishing; therefore, the problems that the fire extinguishing device cannot be started and cannot extinguish fire due to failure of electric signal transmission can be solved, the reliable automatic starting of the fire extinguishing device is ensured, the timeliness and reliability of fire extinguishment are ensured, and the loss caused by fire disaster is effectively reduced.

It should be noted that, similar to the principle of the related art, the one-way pneumatic angle seat valve 161 maintains the closed state when the pressure of the air pipe is greater than the closing pressure thereof, that is, the one-way pneumatic angle seat valve 161 is switched to the closed state when the air pressure increases; when the pressure of the air pipe is smaller than its own closing pressure, the one-way pneumatic angle seat valve 161 is kept in an open state, i.e., is switched to an open state when the air pressure is reduced.

Further, the quick-start linkage fire extinguisher 010 further comprises a spray header 121 connected with the water outlet pipe 120, and the spray header 121 can be assembled in a site protection area; when fire occurs in the area to be protected on site, water can be sprayed out from the spray header 121 to achieve the aim of extinguishing fire.

It should be noted that, referring to fig. 2, the number of the shower heads 121 may be selected according to needs, for example: one, two, three, ten, etc., when the quantity of shower heads 121 is greater than or equal to two, a plurality of shower heads 121 can be in series in proper order, so, can utilize a plurality of shower heads 121 to spray water when the conflagration breaks out, improve the efficiency of putting out a fire, be favorable to reducing the loss that the conflagration brought.

Optionally, the air tank 162 is provided with a safety valve 163, so as to manually discharge the redundant air in the air tank 162, and ensure the safety of the air tank 162 during use; also, after the gas in the gas tank 162 is exhausted, the gas may be refilled through the safety valve 163 so as to reuse the gas tank 162.

Optionally, the air tube 150 is further provided with a valve 151 for opening or closing the air tube 150; if the pressure relief device 200 is not needed, the valve 151 may be used to close the air tube 150.

Optionally, the air reservoir 162 is further provided with a barometer 164 for monitoring the air pressure within the air reservoir 162.

Referring to fig. 1 and 3, the pressure relief device 200 of the present embodiment includes a pull rope 210 and a pressure relief assembly 220, the pressure relief assembly 220 is disposed on the air pipe 150, one end of the pull rope 210 is connected to the pressure relief assembly 220, and the other end extends to the shower head 121; when the pull-cord 210 breaks, the pressure relief assembly 220 can be enabled to vent the gas within the gas reservoir 162.

When a fire breaks out in the field protection area and blows or blows the pull rope 210 extending to the shower head 121, the pressure relief assembly 220 can discharge the gas in the gas tank 162, so that the gas pressure in the gas tank 162 drops, and when the gas pressure in the gas tank 162 drops below the closing pressure of the one-way pneumatic angle seat valve 161, the one-way pneumatic angle seat valve 161 is opened, so that the water in the water inlet pipe 110 can flow to the water outlet pipe 120 and spray out from the shower head 121 to extinguish the fire. Therefore, when a fire disaster occurs in the field protection area, the linkage fire extinguishing device 010 capable of being started quickly can be started smoothly and reliably, the fire extinguishing timeliness and reliability are ensured, the fire extinguishing device cannot be started due to failure in sending fire extinguishing electric signals, and the loss caused by the fire disaster is effectively reduced.

It should be noted that, after the end of the pull rope 210 away from the pressure relief assembly 220 extends to the shower head 121 and is connected to the shower head 121, the assembly stability of the pull rope 210 can be ensured, and the pull rope 210 is ensured to reliably close the pressure relief assembly 220 when no fire occurs, so as to avoid unexpected leakage of the gas in the gas storage tank 162.

It should be further noted that, in an embodiment where the number of the shower heads 121 is greater than or equal to two, one end of the hauling rope 210 far away from the pressure relief assembly 220 may be sequentially wound around the plurality of shower heads 121 and then connected to one of the shower heads 121; thus, if a fire occurs, the fire is facilitated to blow the traction ropes 210 distributed among the plurality of spray headers 121, so that the pressure relief assembly 220 is opened, and the pressure relief assembly 220 can discharge the gas in the gas storage tank 162.

Referring to fig. 1 and 3, in the present embodiment, the pressure relief assembly 220 includes a protection cover 230, a weight 240 and a piston 250, one end of the fireproof cover is communicated with the air pipe 150, and a side wall of the protection cover 230 is provided with an air vent 231; the weight 240 and the piston 250 are movably disposed at the protection cover 230, one end of the traction rope 210 is connected with the weight 240, and the piston 250 is used for communicating the air pipe 150 with the air vent 231 or blocking the passage of the air pipe 150 and the air exhaust pipe 150; when the traction rope 210 breaks, the weight 240 moves downward under the action of its own weight and drives the piston 250 to move to communicate the air pipe 150 with the exhaust pipe 150, so that the air in the air storage tank 162 is exhausted through the air pipe 150 and the exhaust pipe 150 in sequence.

When the fire disaster does not occur in the field protection area, the traction rope 210 reliably lifts the weight 240, the weight 240 does not press on the piston 250, the piston 250 is reliably blocked between the air pipe 150 and the air exhaust hole 231, and the air in the air storage tank 162 does not leak; when a fire occurs in the field protection area, the fire blows the traction rope 210, the counterweight 240 is not pulled by the traction rope 210 any more, falls downwards under the action of self weight, presses the piston 250, drives the piston 250 to move so as to enable the air pipe 150 to be communicated with the exhaust pipe 150, and can discharge the air in the air storage tank 162, and when the air pressure of the air storage tank 162 is reduced to be smaller than the closing pressure of the one-way pneumatic angle seat valve 161, the first water pipe 130 is opened, and water in the water inlet pipe 110 can enter the water outlet pipe 120 and be sprayed out from the spray header 121 to extinguish the fire. In this way, on the one hand, the pressure relief device 200 can be utilized to timely open the fire extinguishing device when a fire occurs, so as to ensure the timeliness and reliability of fire extinguishing, and on the other hand, when no fire occurs, the pressure relief device 200 can also be prevented from accidentally leaking the gas in the gas storage tank 162, and the phenomenon of accidental water spraying of the spray header 121 can be avoided.

Further, the pressure relief assembly 220 further includes an elastic member 260, and the elastic member 260 is connected to the piston 250 for supporting the piston 250. In this way, when no fire occurs, the elastic member 260 supports the piston 250, so that the piston 250 does not drop downwards under the action of self weight, and the passages of the air pipe 150 and the exhaust pipe 150 can be reliably blocked, that is, when the traction rope 210 is not broken, the counterweight 240 is lifted by the traction rope 210, and does not drop under the action of self weight, and then the piston 250 is not pressed and driven to move downwards, and at the same time, the piston 250 is supported by the elastic member 260 and does not drop downwards under the action of self weight, so that the piston 250 can be ensured to be reliably stabilized at the position of blocking the passages of the air pipe 150 and the exhaust pipe 150, and accidental leakage of air in the air storage tank 162 is avoided.

Optionally, the pressure relief assembly 220 further includes a piston seat 270, wherein the piston seat 270 is disposed in the protection cover 230, specifically, the piston seat 270 is disposed at an end of the protection cover 230 near the air pipe 150; the piston seat 270 is provided with a through hole 271, and the piston 250 is movably inserted into the through hole 271 for communicating the air pipe 150 with the exhaust hole 231 or blocking the passage of the air pipe 150 and the exhaust pipe 150. The shape of the shield 230 can be simplified by communicating or blocking the passage between the air pipe 150 and the exhaust pipe 150 by the cooperation of the piston 250 and the piston seat 270, which is advantageous for the production and processing of the shield 230.

Further, the piston 250 includes a piston body 251, a connecting rod 252, and an end plate 253, both ends of the connecting rod 252 being connected to the end plate 253 and the piston body 251, respectively; one end of the elastic member 260 is connected to the piston seat 270, and the other end is connected to the end plate 253, and the end plate 253 is abutted against the weight 240; the piston body 251 serves to communicate the air pipe 150 with the exhaust hole 231 or to block the passage of the air pipe 150 and the exhaust pipe 150. In this way, the reliability of the elastic member 260 supporting the piston 250 can be ensured, and in the case that no fire occurs and the traction rope 210 is not broken, the weight 240 is pulled by the traction rope 210, and does not fall under the action of the dead weight, and further the piston 250 is not pressed and driven to move downwards, and at the same time, the piston 250 is supported by the elastic member 260 and does not fall downwards due to the dead weight, so that the piston 250 can be ensured to be reliably stabilized at the position of blocking the passage of the air pipe 150 and the exhaust pipe 150, and the gas in the gas storage tank 162 is prevented from leaking accidentally. When the traction rope 210 breaks, the counterweight 240 falls under the action of the dead weight and presses on the end plate 253 to overcome the action of the elastic piece 260, so that the piston 250 moves downwards and the air pipe 150 is communicated with the air exhaust hole 231, and then the air in the air storage tank 162 can be exhausted, so that the one-way pneumatic angle seat valve 161 is conveniently opened, the water in the water inlet pipe 110 can flow into the water outlet pipe 120 and be sprayed out from the spray header 121, and the effect of timely fire extinguishment is realized.

It should be noted that the elastic member 260 includes, but is not limited to, a spring, a torsion spring, and an elastic rubber sleeve.

Still further, the piston body 251 is tapered, the through hole 271 is adapted to the piston body 251, and the blocking of the piston body 251 is away from the connection, and the thin end of the piston body 251 is connected to the connecting rod 252. When the traction rope 210 breaks, the counterweight 240 falls under the action of the dead weight and drives the piston 250 to move downwards against the elastic action of the elastic piece 260, the thin end of the piston body 251 moves to a large aperture position close to the through hole 271, so that a gap is formed between the side wall of the piston body 251 and the wall of the through hole 271, the air pipe 150 and the air exhaust hole 231 are communicated through the gap, and the air in the air storage tank 162 can be exhausted through the air pipe 150, the gap and the air exhaust hole 231 in sequence; in this way, when the traction rope 210 breaks due to fire, the gas in the gas storage tank 162 is reliably discharged, the one-way pneumatic angle seat valve 161 opens the first water pipe 130, and water in the water inlet pipe 110 can enter the water outlet pipe 120 and be sprayed out from the spray header 121 to extinguish the fire.

For reliability of exhaust gas; the piston seat 270 is also provided with an air passage 272, and the air passage 272 is communicated with the through hole 271; when the traction rope 210 breaks, the weight 240 falls down and drives the piston 250 to move, a gap is formed between the piston body 251 and the wall of the through hole 271, and the air in the air pipe 150 enters the gap and is conveyed into the fireproof cover through the air passage 272 and is output from the air outlet 231, so that the purpose of pressure relief is achieved.

Further, in order to improve the problem of accidental leakage of the gas in the gas tank 162 when pressure relief is not required; the periphery of the piston body 251 is also connected with a sealing ring 254; when the weight 240 is lifted up by the traction rope 210, the piston 250 is restored to a position where the passage of the air pipe 150 and the exhaust pipe 150 is blocked by the elastic member 260, and the sealing ring 254 is clamped between the piston body 251 and the wall of the through hole 271, thereby performing a sealing function.

In order to facilitate the repeated use of the pressure relief device 200, an insertion hole 232 is formed at one end of the fireproof cover, which is far away from the air pipe 150, a pull rod 241 is connected to one end of the counterweight 240, which is far away from the end plate 253, the pull rod 241 is in insertion fit with the insertion hole 232, and the traction rope 210 is connected with the pull rod 241; when the traction rope 210 breaks, the pull rod 241 can move in the inserting hole 232 and is always inserted into the inserting hole 232. In this way, after fire is extinguished, the pull rod 241 is conveniently forced to pull the counterweight 240 upwards, and a new traction rope 210 can be reconnected to the pull rod 241 so that the counterweight 240 is kept in a pulled state, and meanwhile, the piston 250 moves to block the passage of the air pipe 150 and the air exhaust hole 231 under the action of the elastic member 260, so that the air storage tank 162 can be closed, the reset of the pressure relief device 200 is completed, and the pressure relief device 200 can be used again to automatically open the fire extinguishing device when the next fire occurs.

Referring to fig. 1, the quick-start linkage fire extinguishing apparatus 010 of the present embodiment further includes a second water pipe 140 and a start device, wherein the water outlet pipe 120 and the water inlet pipe 110 are further connected through the second water pipe 140, and the start device is disposed in the second water pipe 140 and is used for opening or closing the second water pipe 140. Thus, the linkage fire extinguishing device 010 capable of being started quickly comprises at least two starting modes, one is to open the first water pipe 130 to realize starting by blowing the traction rope 210 and discharging the gas in the gas storage tank 162, and the other is to open the second water pipe 140 to directly start through the starting device, so that the use flexibility of the fire extinguishing device is ensured.
