[0001] The invention relates to the field of fire prevention facilities, in particular to a combined special device for cooling and breathing protection in fire extinguishing and self-rescue for intelligent indoor fire hydrants. Background Art

[0002] Among various disasters, fire is one of the most frequent and common major disasters threatening public safety and social development, especially in high-rise residential areas. How to achieve self-rescue in high-rise residential fires is a global problem. At the scene of an indoor fire, the fire can spread in a short time, and even explode, which will produce a large amount of toxic smoke and fatal high temperature. In particular, the height of ordinary residential rooms is generally low, and the floor height after the ceiling is about 2.8 meters. A thick layer of smoke can be formed immediately from the top of the fire room downward. There is little oxygen available for breathing in the air, and the high temperature burning sensation is strong. Self-rescue and fire-fighting actions are hindered, posing a serious threat to the lives of fire-fighting and self-rescue personnel. Most of the existing fire-fighting self-rescue protection devices are independent bodies, equipped with few fire-fighting and self-rescue facilities, and have limited protection functions. They cannot safely and effectively deal with the harsh environment of high-temperature toxic gases in the fire scene. Therefore, in response to the above problems, a special cooling and breathing protection combination device for fire-fighting and self-rescue in intelligent indoor fire hydrants is proposed. Summary of the invention

The main water supply manifold is connected to the shoulder spray pipe, the spray pipe around the cap and the spray pipe on the top of the cap through their corresponding branch water supply pipes, and a high temperature resistant heat insulation film is provided on the surface of the main water supply hose.

[0009] Preferably, a second spray hole is opened on the inner side of the spray pipe around the cap portion, and the second spray hole faces the safety helmet. The top spray pipe is located directly above the safety helmet, and the third spray hole on the top spray pipe faces inward.

[0010] Preferably, the spray cooling heat insulating protective clothing is also provided with spray cooling heat insulating protective shoes and protective gloves, and the spray cooling heat insulating protective clothing consists of a protective top and protective pants.

[0011] Preferably, the spray cooling and heat-insulating protective clothing and the protective gloves are divided into three layers, which are, from the inside to the outside, an inner lining composite layer, a high-temperature resistant insulation layer and a waterproof layer; the spray cooling and heat-insulating protective shoes are divided into three layers, which are, from the inside to the outside, an inner lining composite layer, a high-temperature resistant insulation layer and a waterproof and heat-resistant layer.

[0012] Preferably, the homemade hood-type oxygen inhaler also includes an air storage bag, an oxygen generator and a hood, the back of the air storage bag is connected to one end port of the oxygen generator, the oxygen outlet port of the air storage bag and the other end port of the oxygen generator are both located inside the hood, a circular pressure relief valve is arranged on the back of the air storage bag, and the peripheral edge of the back side of the hood is fixedly connected to the edge corresponding to the neck water ingress prevention enclosure cover.

[0013] Preferably, universal wheels with brakes are installed at the bottom of the first retractable leg and the front of the bottom of the second retractable leg, a guide tube is fixed in the middle of the triangular hole seat, and the inner wall of the guide tube is in sliding contact with the corresponding part of the retractable lifting tube.

[0014] The beneficial effects of the present invention are: 1. A sustainable water spray pipe is installed through the output port of the third control valve, which can continuously spray and cool down all parts of the firefighters from the top of their heads to the surrounding areas when they are facing the fire. The spray holes distributed just below the bottom of the shoulder spray pipe and the spray holes inclined downward at 45 degrees can form a cone spray cooling structure centered on the human body, which not only protects the hands and two whole arms extending forward to operate the water gun, but also protects the two shoulders and all parts of the human body below, ensuring that the firefighters are not burned and not disturbed by high temperature, so that water spraying firefighting can be effectively implemented; 2. The distributed spray holes 2 and 3 implement all-round spray cooling on the surface of the helmet they are facing. The helmet ensures the head safety of the fire-fighting and rescue personnel. A front cap head water interception and diversion brim is set in front of the helmet, which can intercept the water spraying to the helmet and flow out from both sides of the helmet, ensuring a clear control field in front of the fire-fighting. At the same time, when overheat radiation appears in front of the mask, the intercepted water is made to flow downward by lowering the head, and the front of the mask is instantly cooled by water. The waterproof and sealed lithium flashlight above the front of the helmet provides lighting for the power-off fire scene and the mobile fire-fighting bracket workbench, ensuring that the corresponding work is not affected by darkness. The spray cooling above the front of the helmet ensures the normal operation of the lighting device in an ultra-high temperature environment. The height difference between the spray ring and the shoulder allows firefighters to flexibly and three-dimensionally and all-roundly twist the entire hood-type spray ring, and compensate for the radiant heat appearing at the local point under the head with spray water, further supplementing the cooling protection. 3. The shoulder sprinkler pipe, the sprinkler pipe around the cap and the sprinkler pipe on the top of the cap are all connected with the output port of the main water supply manifold by independent branch water supply pipes, which avoids the phenomenon that the cooling fire water flowing from the upper-level perforated sprinkler ring to the lower-level perforated sprinkler ring and the vertical perforated sprinkler ring connected to the upper and lower sprinkler rings will have smaller pressure and flow values ​​as the water column moves backwards during the entire downward and forward flow process due to the pressure relief water sprayed through the holes in sequence. This setting allows the sprinkler ring pipes at the upper, middle and lower levels to independently obtain the fire water flowing through the fire gun from the main water supply manifold, ensuring the sufficiency of the sprinkler water pressure, flow rate and range in each sprinkler pipe, effectively ensuring the realization of cooling protection and the normal implementation of water-jet fire extinguishing work; 4. Use the spray liquid to cool the surface of the air storage bag to ensure that the temperature of the oxygen in the oxygen storage bag is within the safe inhalation range, and prevent the high-temperature oxygen from burning the lungs; the circular pressure relief valve on the back of the oxygen storage bag ensures that when the excess oxygen pressure generated instantly or the gas pressure inside the oxygen storage bag is too high due to excessive heat absorption, the air can be exhausted and the pressure can be relieved immediately to ensure that it is always in a safe oxygen supply state at normal temperature and pressure; the spray liquid covers the surface of the sealed metal oxygen generating tank with a jet, which effectively reduces the large amount of heat generated by the agent in the tank during the oxygen production process and transmitted to the metal tank shell, preventing the high heat and the radiant heat absorbed by the metal shell from the fire scene from accidentally burning people and objects.

[0015] 5. The mobile bracket of the fire gun and the mobile chair frame form a retractable and foldable integrated bracket structure. The high-temperature resistant seat plate that can be folded freely can not only stably support the normal operation of the self-rescuer, but also has excellent flame retardant and heat resistant properties, and provides secondary protection for the operator against high-temperature burns. The overall device is easy to store, occupies a small space, and is easy to take out, unfold, move and use. The support height of the fire hose is based on the normal downward slanting height of an adult sitting position as the reference method, so as to ensure that the clear field of vision of the firefighters operating the fire gun upward to extinguish the fire in a sitting position is within one meter from the working floor height, while avoiding the toxic smoke layer gathered on the top of the fire room, etc., which enhances the convenience, stability and accuracy of the firefighters' operation of the fire gun, and the fire extinguishing and rescue methods and effects.

[0016] 6. The retractable lifting tube of the mobile fire-fighting support workbench is pulled out and in a fixed state, and the universal angle balancer of the water gun connected to it can be moved up to a height position based on the height of an adult sitting position. The deadweight of the sitting firefighter constrains the two retractable legs on the mobile chair frame, making it immobile, thereby increasing the stability of the mobile fire-fighting support workbench; the rear end of the fire-fighting gun is fixedly connected to the top of the universal angle balancer through the rear end clamp connector of the water gun, and the recoil force generated by the water ejected from the front end of the muzzle and the deadweight of the sitting human body, The water gun has a cleverly balanced force at the golden section point of the water gun barrel torque, which not only ensures the stability of the water gun installation, but also ensures the ease and flexibility of the water gun in implementing the three-dimensional water-jetting fire-fighting action; the output ports at the upper and lower ends of the water gun are equipped with foldable and movable metal pipe spray tongues, which can be controlled to intermittently or continuously spray and cool down the lower body, legs, feet, front or other parts of the firefighter facing the fire scene according to the feeling of radiant heat during the fire-fighting process, ensuring the normal implementation of the water-jetting fire-fighting work; 7. Spray cooling and heat insulation protective clothing, protective shoes and protective gloves are made of soft functional materials, special waterproof zippers, double elastic elastic embedded solid laces and other specific structures and combinations. They are not only convenient and quick to wear during emergency rescue or practical exercises, but also comfortable after wearing. They can also be flexibly operated during the fire fighting process without being restrained, which plays a positive role in improving the efficiency of fire fighting operations. At the same time, the good waterproof performance enables the fire fighting operators to keep their bodies dry and comfortable during the entire rescue process, and its waterproof spraying effect keeps the human body at a normal temperature without being hot in the high-temperature fire scene; the high-temperature resistant insulation layer in the middle further consolidates the secondary protective effect of the spray cooling of the waterproof layer, and also isolates the discomfort of the human body caused by the low temperature on the surface of the protective clothing due to continuous spray cooling; in addition to the strong comfort and protection of waterproof and heat insulation, the protective shoes have built-in specific steel structures, thickened soles and heels, and other characteristics, which further ensure the safety of the feet, especially in the messy fire scene where pressure and puncture injuries are more likely to occur.

[0021] The technical solution of the present invention is further described below with reference to the accompanying drawings and through specific implementation methods.

[0022] In the description of the present invention, it is necessary to understand that the orientations or positional relationships indicated by the terms "upper", "lower", "top", "bottom", "inside", "outside", etc. are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] See also Figure 1-15 As shown, a special device for cooling breathing protection combination for fire extinguishing and self-rescue for intelligent indoor fire hydrants includes a fire gun self-rescue fire extinguishing mobile bracket workbench 1, a head cover type combined sprinkler pipe assembly 2 and a spray cooling and heat insulation protective clothing 3. The fire gun self-rescue fire extinguishing mobile bracket workbench 1 includes a fire gun 110, a fire gun mobile bracket 120 and a movable chair frame 130. The output port of the first control valve 111 located on the rear end of the fire gun 110 and the total water supply distributor 240 located on the top of the head cover type combined sprinkler pipe assembly 2 are connected to each other through a total water supply hose 260. The output port of the second control valve 112 located at the side of the rear end of the fire gun 110 is installed with a foldable metal tube 114, and a spray tongue is installed at one end of the foldable metal tube 114. The output port of the third control valve 113 located below the front end of the fire gun 110 is installed with a sustainable water spray pipe, and the surface of the total water supply hose 260 is provided with a high temperature resistant heat insulation film 261. Combination Figure 2 As shown, the first control valve 111 is opened, and the water flowing through the fire gun 110 is diverted to the head cover type combined sprinkler pipe assembly 2 connected to the main water supply hose 260 and the main water supply distributor 240, so as to supply water to the shoulder sprinkler pipe 210, the sprinkler pipe 220 around the cap, and the sprinkler pipe 230 on the cap top in the head cover type combined sprinkler pipe assembly 2; A main water supply hose 260 with a high temperature resistant heat insulation film 261 on the surface is used to replace the traditional relatively hard pipe body, thereby reducing the operational resistance of installation and movement due to the high hardness of the pipe body, and is lightweight and high temperature resistant; The second control valve 112 connected to the foldable metal tube 114 can be opened according to the needs of the firefighters, and the spray tongue at the end of the foldable metal tube 114 can be adjusted in any direction to spray and cool the firefighters' clothes and the surrounding environment, thereby achieving the effect of strengthening the spray and cooling of the designated area. A sustainable water spray pipe is installed through the output port of the third control valve 113, which can continuously spray and cool the lower body part of the firefighters facing the fire and the surrounding areas.

[0024] The rear end of the fire gun 110 is fixedly connected to the top of the universal angle balancer 121 through the rear end clamp connector 180 of the water gun, and the bottom of the universal angle balancer 121 is fixedly connected to the top of the retractable lifting tube 124 located in the mobile bracket 120 of the fire gun; Combination Figure 1 and Figure 5 As shown, when the fire-fighting gun mobile bracket 120 is in the unfolded use state, the retractable lifting tube 124 is pulled out and is in a fixed state, and the universal angle balancer 121 connected thereto can be moved up to a height position based on the height of an adult sitting position, so as to ensure that the visual field height of the firefighter operating the fire-fighting gun 110 upward to extinguish the fire in a sitting position is within 1 meter; When the universal angle balancer 121 is installed, the firefighters fix the rear end of the fire gun 110 and the water gun rear end clamp connector 180 located on the universal angle balancer 121 to each other.

[0025] The neckline of the spray cooling and heat insulating protective clothing 3 is covered by a neck water-proof enclosure 540 located in the self-made hood-type oxygen inhaler 5; Combination Figure 7 As shown, the neck water-proof enclosure 540 is used to cover the collar of the spray cooling heat-insulating protective clothing 3 to prevent the spray liquid from flowing into the spray cooling heat-insulating protective clothing 3.

[0026] The head cover type combined spray pipe assembly 2 includes a shoulder spray pipe 210, a spray pipe 220 around the cap, a spray pipe 230 on the cap top and a total water supply manifold 240. Spray holes 211 are evenly distributed directly below and laterally of the shoulder spray pipe 210, and the spray hole 211 located on the side is inclined downward at 45 degrees. The spray pipe 220 around the cap and the spray pipe 230 on the cap top form a spray cooling structure for the safety helmet 4. The spray pipe 220 around the cap has a spray hole 221 on the inner side, and the spray hole 221 faces the safety helmet 4. The spray pipe 230 on the cap top is located directly above the safety helmet 4, and the spray hole 231 on the spray pipe 230 on the cap top faces inward. A front cap head water interception and diversion brim 410 is provided in front of the safety helmet 4. Combination Figure 3 , Figure 4 and Fig.10 As shown, the spray hole 211 distributed directly below the bottom of the shoulder spray pipe 210 and the spray hole 211 slanting downward at 45 degrees can form a cone-shaped spray cooling structure centered on the human body; The distributed spray holes 221 and 231 implement all-round spray cooling on the surface of the helmet 4 they face. At the same time, a front cap head water interception and diversion brim 410 is arranged in front of the helmet 4, which can intercept the water spraying to the helmet 4 and flow out from both sides of the helmet 4, and try to avoid the generation of a continuous water column or water curtain in front of the mask to affect the clear field of vision required for fire extinguishing control. At the same time, when overheat radiation appears in front of the mask, the intercepted water is made to flow downward by lowering the head, and the front of the mask is cooled by water; the bottom edge of the spray ring is located several centimeters above the shoulder, that is, the height difference space between the overall height of the spray ring and the shoulder, which ensures that when the firefighters feel that there is radiant heat at a local point somewhere under the head, they can flexibly twist to the left shoulder or the right shoulder, forward or backward, to compensate and cover the spray water, and further implement cooling protection for the radiant heat at the local point; When the firefighter opens the relevant control valve, such as operating the hood-type combined sprinkler pipe assembly 2, the firefighter needs to understand how to ensure the stability of the water pressure sprayed by the fire gun 110: the remote control box 140 on the fire gun 110 can be wirelessly connected to the intelligent fire hydrant. The firefighter remotely opens the hydraulic valve for the intelligent indoor fire hydrant through the on / off key of the remote control box 140, so that the water gun can shoot water to extinguish the fire. The hood-type combined sprinkler pipe assembly enters the working state at the same time. When the continuous synchronous button is actuated after the water is discharged, that is, the operation of the raising / lowering stabilizing button is pressed, the whole equipment enters the state of constant pressure of total water supply. Even if the water pressure at the fire gun 110 rises and falls due to the instantaneous opening and closing of the water supply sprinkler lowering device, the original water pressure, range and flow rate of the muzzle can be immediately restored, ensuring that the different constant pressure water shooting combat readiness states required at each stage of the whole process of fire fighting at the fire scene can be implemented normally; The intelligent fire hydrant is a hydraulic valve for intelligent indoor fire hydrants in CN 115006771 B in the prior art.

[0027] Combination Fig.14 and Fig.15 As shown, three buttons 141 are installed on the top surface of the remote control box 140, and each button 141 is equipped with a waterproof indicator light 142. A control execution module 145, a signal receiving and releasing module 146, a charging control module 147 and a power storage module 148 are installed on the PCB board inside the remote control box 140. The charging control module 147 is electrically connected to a magnetic flat-head charging seat 144 located at one end of the side of the remote control box 140, and the power storage module 148 is electrically connected to a power switch 143 located at the other end of the side of the remote control box 140. The three buttons 141 are respectively a step-down stabilization button, a step-up stabilization button and an on / off button.

[0028] Two strap connectors are symmetrically installed at the bottom of the rear end of the shoulder spray pipe 210, and a portion of the pipe section at the front end of the shoulder spray pipe 210 is a reversible pipe section 212; Specific as Figure 4 As shown, the reversible tube 212 section can be turned outward when in use to increase the spray cooling range, and can be turned inward to the inner area of ​​the shoulder spray tube 210 when not in use to reduce the space occupied by storage.

[0029] The fire gun mobile bracket 120 includes three first retractable legs 122, a triangular hole seat 123 and a hinge 125; the middle part of the inner side of the three first retractable legs 122 and the bottom of the retractable lifting tube 124 are movably connected through a hinge 125, and the top of each first retractable leg 122 is movably connected to the corresponding corner located on the triangular hole seat 123, and a guide tube 126 is fixed in the middle of the triangular hole seat 123, and the inner wall of the guide tube 126 is in sliding contact with the corresponding part of the retractable lifting tube 124; The movable chair frame 130 includes a high temperature resistant seat plate 131, three second retractable legs 132, a back support plate 133, and a hinge 134. One end of the three second retractable legs 132 is movably connected to the bottom of the support plate, and the middle parts of the three second retractable legs 132 are mutually connected through hinges 134. One side of the high temperature resistant seat plate 131 and the edge of the back support plate 133 are mutually hinged, and the bottom ends of two second retractable legs 132 are respectively connected to the bottom ends of two first retractable legs 122 by hinges. Combination Figure 5 and Figure 6 As shown, the fire gun mobile bracket 120 and the mobile chair frame 130 form a retractable and foldable integrated bracket structure, and the specific steps of using it in conjunction with the fire gun 1 are as follows: Step 1: The firefighter takes out the fire gun self-rescue fire extinguishing mobile bracket workbench 1 folded and stored in the box.
