Description

Technical Field

[0001] The present invention relates to the technical field of fire extinguishing equipment, and specifically relates to a fire extinguishing equipment that can prevent high temperature. Background Art

[0002] Fire is a very serious disaster. The occurrences of fires include those caused by nature and those caused by humans. Whether caused by nature or humans, the destructive power of fires is extremely huge, not only causing huge economic losses, but sometimes also causing a large number of casualties. Fire protection work includes controlling and eliminating various potential safety hazards, among which the most important is to control and eliminate the occurrence and spread of fires and explosions; the vast majority of fires start from tiny fire situations and, due to lack of timely control, spread instantly to form serious disasters, bringing serious losses to the people and society. When extinguishing fires, fire extinguishing equipment is needed.

[0003] Currently, most existing fire extinguishing is carried out by firefighters using fire ladders to lift up and spray water to extinguish the fire. This can extinguish the fire, but there are also significant limitations. For the inner corners of houses or some remote places, it is simply impossible to extinguish the fire in time, and it is easy to leave residual sparks and flames, causing secondary fires, posing a great safety hazard to firefighters' inspections. Summary of the Invention

[0004] To achieve the above objectives, the present invention is realized through the following technical solutions: A fire extinguishing equipment that can prevent high temperature, including a protective housing. An observation window is fixedly connected to the outer surface of the protective housing. A fire extinguishing treatment device is arranged on the outer surface of the protective housing and near the observation window. A pressure-receiving air intake device is arranged on the inner surface of the protective housing and near the fire extinguishing treatment device. A heat insulation layer is fixedly connected to the inner surface of the protective housing. A guide rail is fixedly connected to the outer surface of the protective housing. An anti-tipping device is arranged on the outer surface of the protective housing and near the guide rail. A safety door is snap-connected to the outer surface of the protective housing. By opening the safety door, at this time, firefighters carry fire extinguishers into the protective housing, snap the safety door on the outer surface of the protective housing, and with the support of the anti-tipping device, by firefighters walking inside the protective housing, the protective housing rolls. Use the observation window to observe the external situation, move towards the inner corners or remote places in the house, and use the forward and reverse rotations of the protective housing to achieve forward and backward movement. When approaching the fire source, use the protection of the protective housing for firefighters to reduce the risk of being injured by the collapse of the house. It has strong adaptability, and use the heat insulation layer to insulate the external temperature and reduce the influence of high temperature;

[0005] The fire extinguishing treatment device includes a through hole which is opened on the outer surface of the protective housing. The inner surface of the through hole is fixedly connected with a curved elastic disc. The central position of the outer surface of the curved elastic disc is fixedly connected with a fire extinguishing device. The outer surface of the fire extinguishing device is fixedly connected with a pushing member. At the same time, the firefighter aligns the outlet end of the fire extinguisher with the inlet end of the fire extinguishing device and sprays the fire extinguishing medium towards the center of the fire source. By using the elasticity of the curved elastic disc itself and the through hole which can increase the rotation range of the fire extinguishing device, it helps to quickly extinguish the fire.

[0006] Preferably, the protective housing is arranged in a cylindrical shape. The observation windows are evenly distributed on the outer surface of the protective housing. The pressure-receiving air inlet devices are evenly distributed on the inner surface of the protective housing and close to the fire extinguishing treatment device.

[0007] Preferably, the fire extinguishing device includes a medium spray tube. The outer surface of the medium spray tube is fixedly connected with the central position of the outer surface of the curved elastic disc. A blocking device is arranged inside the medium spray tube and close to the top position. The bottom end of the medium spray tube is arranged as a flared opening. The inner surface of the flared opening is rotatably connected with a rotating wheel through a bracket. The outer surface of the rotating wheel is fixedly connected with a spiral blade. When the protective housing rolls to the vicinity of the fire source, the fire extinguishing device on the side of the outer surface of the protective housing close to the fire source is in front of the fire door.

[0008] Preferably, the outer surface of the rotating wheel is arranged in a conical shape. The spiral blades are evenly distributed on the outer surface of the rotating wheel.

[0009] Preferably, the blocking device includes an elastic rod. The bottom end of the elastic rod is fixedly connected with the inner surface of the medium spray tube. The top end of the elastic rod is fixedly connected with a blocking block. The central position of the top of the blocking block is fixedly connected with a spherical head push rod. The top of the outer surface of the spherical head push rod is fixedly connected with a pressure-receiving tooth. At this time, the firefighter connects the outlet end of the fire extinguisher with the inlet of the medium spray tube. Under the action of the top pressure at the outlet end of the fire extinguisher, the pressure-receiving tooth applies the top pressure to the spherical head push rod. At this time, the blocking block is pushed and compresses the elastic rod. And the sprayed fire extinguishing medium is used for extinguishing the fire through the delivery of the medium spray tube. Moreover, the other elastic rods on the outer surface of the protective housing are not compressed. At this time, the other medium spray tubes are still blocked, so that the floating smoke is not easy to enter the inside of the protective housing, reducing the harm to the firefighters. At the same time, by using the pressure of the fire extinguishing medium sprayed by the fire extinguisher, the rotating wheel drives the spiral blade to rotate at a high speed, so that the sprayed medium is affected by the swirl, and then the medium can be sprayed at a far distance, so that the protective housing can be a little farther away from the fire source to ensure safety.

[0010] Preferably, the pressurized air intake device includes an air intake hole opened on the outer surface of the protective housing. A support housing is fixedly connected to the inner surface of the protective housing near the air intake hole. A conical hopper is fixedly connected and communicated with the top of the support housing. A driven opening device is arranged inside the conical hopper.

[0011] Preferably, the driven opening device includes a guide frame. The outer surface edge of the guide frame is fixedly connected to the inner surface of the conical hopper. A sliding rod is slidably connected to the central position of the outer surface of the guide frame. A return spring is fixedly connected to the bottom end of the outer surface of the sliding rod. The top end of the return spring is fixedly connected to the bottom of the guide frame. A piston disc is fixedly connected to the top end of the sliding rod. A hook is fixedly connected to the top of the piston disc. When the protective housing stops rolling, the bottom end of the medium spray tube at the bottom of the protective housing contacts the ground, and thus receives an upward driving force. The other medium spray tubes are not under pressure. Using the pressure of the protective housing itself and combining with the elastic force of the curved elastic disc, the medium spray tube moves upward, thereby driving the jacking member to move upward, and then applying an upward jacking force to the hook. Combining with the fact that the sliding rod can be slidably connected to the center of the guide frame, the piston disc moves upward smoothly, and thus the outer surface of the piston disc is separated from the inner surface of the conical hopper, thereby opening the conical hopper and allowing the air near the ground to enter the protective housing. As the smoke rises, there is little smoke near the ground, thus ensuring the entry of oxygen into the protective housing to provide oxygen for the firefighters. The other piston discs are not subjected to the pulling force of the hook and remain in the blocked state.

[0012] Preferably, a sliding hole adapted to the sliding rod is opened at the central position of the outer surface of the guide frame. The outer surface of the piston disc fits with the inner surface of the conical hopper.

[0013] Preferably, the anti-tipping device includes a diamond-shaped support member. The outer surface of the diamond-shaped support member is slidably connected to the outer surface of the guide rail. A stabilizing leg is fixedly connected to the side of the outer surface of the diamond-shaped support member away from the guide rail. A roller is installed at the bottom end of the stabilizing leg. A pedal is fixedly connected to the outer surface of the stabilizing leg near the protective housing. When the protective housing is rolling, the bottom of the roller contacts the ground, and combining with the fact that the outer surface of the diamond-shaped support member is slidably connected to the outer surface of the guide rail, the end of the diamond-shaped support member can slide along the outer surface of the guide rail, making the protective housing roll smoothly. The stabilizing leg supports the whole protective housing, making the protective housing not prone to tipping, and the overall stability is good. At the same time, the pedal is used to reinforce and support the stabilizing leg, making the stabilizing leg have high strength and not easy to bend or deform. It is also possible to step on the pedal to facilitate the firefighters to enter the protective housing.

[0014] Preferably, the guide rail is arranged as a circular closed loop, and a sliding groove adapted to the outer surface of the diamond-shaped support member is formed on the outer surface of the guide rail.

[0015] The present invention provides a fire-fighting equipment for preventing high temperature, which has the following beneficial effects:

[0016] First, for this fire-fighting equipment for preventing high temperature, the safety door is clamped on the outer surface of the protective housing, and with the support of the anti-tipping device, the fireman walks inside the protective housing, causing the protective housing to roll. By observing through the observation window, it moves towards the corners or remote places inside the house, and realizes forward and backward movement by the forward and reverse rotation of the protective housing. When approaching the fire source, the protection of the fireman by the protective housing can reduce the injury caused by the collapse of the house. It has strong adaptability, and the heat insulation layer insulates the external temperature, reducing the influence of high temperature. At the same time, the fireman aligns the outlet end of the fire extinguisher with the inlet end of the fire extinguishing device, sprays the fire extinguishing medium towards the center of the fire source, and utilizes the elasticity of the curved elastic disc itself, and the through holes can increase the rotation range of the fire extinguishing device, thus contributing to rapid fire extinguishing.

[0017] Second, for this fire-fighting equipment for preventing high temperature, when the protective housing is rolling, the bottom of the roller contacts the ground, and combined with the sliding connection between the outer surface of the diamond-shaped support member and the outer surface of the guide rail, the end of the diamond-shaped support member can slide along the outer surface of the guide rail, making the rolling of the protective housing smooth. And the stabilizing legs support the whole protective housing, making the protective housing not easy to tip over, so that the overall stability is good. At the same time, the pedal is used to reinforce and support the stabilizing legs, making the stabilizing legs have high strength and not easy to bend or deform. Also, by stepping on the pedal, it is convenient for the fireman to enter the protective housing.

[0018] Third, for this fire-fighting equipment for preventing high temperature, when the protective housing rolls near the fire source, the fire extinguishing device on the side of the outer surface of the protective housing close to the fire source is in front of the fire door. At this time, the fireman connects the outlet end of the fire extinguisher with the inlet of the medium spray tube. Under the top pressure of the outlet end of the fire extinguisher, the pressure teeth apply the top pressure to the spherical head rod. At this time, the blocking block is pushed, compressing the elastic rod, and the sprayed fire extinguishing medium is used to extinguish the fire through the delivery of the medium spray tube. Moreover, the other elastic rods on the outer surface of the protective housing are not compressed, and at this time, the other medium spray tubes are still blocked, so that the floating smoke is not easy to enter the interior of the protective housing, reducing the harm to the fireman. At the same time, using the pressure of the fire extinguishing medium sprayed by the fire extinguisher, the rotating wheel drives the spiral blade to rotate at a high speed, making the sprayed medium receive a swirl, and then the medium can be sprayed far away, so that the protective housing can be a little farther away from the fire source to ensure safety.

[0019] IV. For the high-temperature-proof fire extinguishing equipment, when the protective housing stops rolling, the bottom end of the medium spray nozzle at the bottom of the protective housing contacts the ground, and thus receives an upward driving force. The other medium spray nozzles are under no pressure. By using the pressure of the protective housing itself and combining with the elastic force of the curved elastic disc, the medium spray nozzle moves upward, thereby driving the jacking member to move upward, and then applying an upward jacking force to the grab hook. And since the sliding rod can be slidably connected to the center of the guide frame, the piston disc moves upward smoothly, so that the outer surface of the piston disc is separated from the inner surface of the conical hopper, thereby opening the conical hopper, allowing the air near the ground to enter the protective housing. As the smoke rises, there is very little smoke near the ground, thus ensuring that oxygen enters the protective housing to provide oxygen for the firefighters. The other piston discs are not subjected to the pulling force of the grab hook and remain in the blocked state, reducing the entry of smoke. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0030] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation manners. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form.

[0032] The fire extinguishing treatment device 3 includes a through hole 31, the through hole 31 is opened on the outer surface of the protective housing 1, a curved elastic disk 32 is fixedly connected to the inner surface of the through hole 31, a fire extinguishing device 33 is fixedly connected to the central position of the outer surface of the curved elastic disk 32, and a top moving part 34 is fixedly connected to the outer surface of the fire extinguishing device 33.

[0033] The protective housing 1 is arranged in a cylindrical shape, the observation windows 2 are uniformly distributed on the outer surface of the protective housing 1, and the pressure-receiving air intake devices 4 are uniformly distributed on the inner surface of the protective housing 1 and close to the fire extinguishing treatment device 3.

[0034] By opening the safety door 8, at this time, firefighters carry fire extinguishers into the protective housing 1, and snap the safety door 8 on the outer surface of the protective housing 1. With the support of the anti-tipping device 7, as the firefighters walk inside the protective housing 1, the protective housing 1 rolls. By observing through the observation window 2, it moves towards the corners or remote places inside the house, and by the forward and reverse rotations of the protective housing 1, it moves forward and backward. When approaching the fire source, the protection of the firefighters by the protective housing 1 can reduce the risk of being injured by the collapse of the house, with strong adaptability. Moreover, the heat insulation layer 5 is used to insulate the external temperature, reducing the influence of high temperature. At the same time, the firefighters align the outlet end of the fire extinguisher with the inlet end of the fire extinguishing device 33 and spray the fire extinguishing medium towards the center of the fire source. With the elasticity of the curved elastic disk 32 itself, and the through holes 31 can increase the rotation range of the fire extinguishing device 33, which helps to quickly extinguish the fire.

[0035] The fire extinguishing device 33 includes a medium spray tube 331. The outer surface of the medium spray tube 331 is fixedly connected to the central position of the outer surface of the curved elastic disk 32. A blocking device 332 is arranged inside the medium spray tube 331 and near the top position. The bottom end of the medium spray tube 331 is set as a flared mouth 333. A rotating wheel 334 is rotatably connected to the inner surface of the flared mouth 333 through a bracket. A spiral blade 335 is fixedly connected to the outer surface of the rotating wheel 334.

[0036] The outer surface of the rotating wheel 334 is conical, and the spiral blades 335 are evenly distributed on the outer surface of the rotating wheel 334.

[0037] The plugging device 332 includes an elastic rod 3321. The bottom end of the elastic rod 3321 is fixedly connected to the inner surface of the medium spray tube 331. The top end of the elastic rod 3321 is fixedly connected with a plugging block 3322. At the central position of the top of the plugging block 3322, a spherical head push rod 3323 is fixedly connected. On the outer surface of the top of the spherical head push rod 3323, a pressure-receiving tooth 3324 is fixedly connected. When the protective housing 1 rolls to near the fire source, the fire extinguishing device 33 on the side of the outer surface of the protective housing 1 close to the fire source is in front of the fire door. At this time, the firefighter connects the outlet end of the fire extinguisher to the inlet of the medium spray tube 331. Under the top pressure of the outlet end of the fire extinguisher, the pressure-receiving tooth 3324 applies the top pressure to the spherical head push rod 3323. At this time, the plugging block 3322 is pushed, and the elastic rod 3321 is compressed. And the fire extinguishing medium is sprayed out and extinguished through the delivery of the medium spray tube 331. Moreover, the other elastic rods 3321 on the outer surface of the protective housing 1 are not compressed. At this time, the other medium spray tubes 331 are still plugged, so that the floating smoke is not easily introduced into the interior of the protective housing 1, reducing the harm to the firefighters. At the same time, using the pressure of the fire extinguishing medium sprayed by the fire extinguisher, the rotating wheel 334 drives the spiral blade 335 to rotate at a high speed, so that the sprayed medium is swirled, and then the medium is sprayed out at a long distance, so that the protective housing 1 can be a little farther away from the fire source to ensure safety.

[0038] Embodiment 2, as Figures 6 - 8 shown, the pressure-receiving air intake device 4 includes an air intake hole 41, and the air intake hole 41 is opened on the outer surface of the protective housing 1. At the position on the inner surface of the protective housing 1 close to the air intake hole 41, a support housing 42 is fixedly connected. At the top of the support housing 42, a conical hopper 43 is fixedly connected and communicated. Inside the conical hopper 43, a driven opening device 44 is arranged.

[0039] The driven opening device 44 includes a guide frame 441. The outer surface edge of the guide frame 441 is fixedly connected to the inner surface of the conical hopper 43. At the central position of the outer surface of the guide frame 441, a sliding rod 442 is slidably connected. At the bottom end of the outer surface of the sliding rod 442, a reset elastic member 443 is fixedly connected. The top end of the reset elastic member 443 is fixedly connected to the bottom of the guide frame 441. The top end of the sliding rod 442 is fixedly connected with a piston disk 444. At the top of the piston disk 444, a hook 445 is fixedly connected.

[0040] At the central position of the outer surface of the guide frame 441, a sliding hole adapted to the sliding rod 442 is opened. The outer surface of the piston disk 444 is attached to the inner surface of the conical hopper 43.

[0041] When the rolling of the protective housing 1 stops, the bottom end of the medium spray tube 331 at the bottom of the protective housing 1 contacts the ground, and thus receives an upward driving force. The remaining medium spray tubes 331 are not under pressure. By using the pressure of the protective housing 1 itself and combining with the elastic force of the curved elastic disk 32, the medium spray tube 331 moves upward, thereby driving the pushing member 34 to move upward, and then applying an upward pushing force to the hook 445. Combining with the fact that the sliding rod 442 can be slidably connected to the center of the guide frame 441, the piston disk 444 moves upward smoothly, so that the outer surface of the piston disk 444 is separated from the inner surface of the conical hopper 43, thereby opening the conical hopper 43, allowing the air near the ground to enter the protective housing 1. As the smoke rises, there is very little smoke near the ground, thus ensuring the entry of oxygen into the protective housing 1 to provide oxygen for the firefighters. The remaining piston disks 444 are not subjected to the pulling force of the hook 445 and remain in the blocked state, reducing the entry of smoke.

[0042] Embodiment 3, as Figure 9 shown, the anti-tipping device 7 includes a rhombic support member 71. The outer surface of the rhombic support member 71 is slidably connected to the outer surface of the guide rail 6. A stabilizing leg 72 is fixedly connected to the outer surface of the rhombic support member 71 and away from the guide rail 6. A roller 73 is installed at the bottom end of the stabilizing leg 72. A pedal 74 is fixedly connected to the outer surface of the stabilizing leg 72 and near the position of the protective housing 1.

[0043] The guide rail 6 is arranged as a circular closed loop, and a sliding groove adapted to the outer surface of the rhombic support member 71 is formed on the outer surface of the guide rail 6.

[0044] When the protective housing 1 rolls, by using the bottom of the roller 73 to contact the ground and combining with the fact that the outer surface of the rhombic support member 71 is slidably connected to the outer surface of the guide rail 6, the end of the rhombic support member 71 can slide along the outer surface of the guide rail 6, making the rolling of the protective housing 1 smooth. And the stabilizing leg 72 supports the whole protective housing 1, making the protective housing 1 not easy to tip over, so that the overall stability is good. At the same time, by using the pedal 74 to reinforce and support the stabilizing leg 72, the stabilizing leg 72 has high self-strength and is not easy to bend or deform. It is also convenient for firefighters to enter the protective housing 1 by stepping on the pedal 74.

[0045] During use, by opening the safety door 8, at this time, firefighters carry fire extinguishers and enter the protective housing 1, and snap the safety door 8 onto the outer surface of the protective housing 1. When the protective housing 1 rolls, the bottom of the roller 73 contacts the ground, and combined with the outer surface of the diamond-shaped support 71 slidingly connected to the outer surface of the guide rail 6, the end of the diamond-shaped support 71 can slide along the outer surface of the guide rail 6, making the protective housing 1 roll smoothly. Moreover, the stabilizing legs 72 support the entire protective housing 1, making it not easy for the protective housing 1 to tip over, resulting in good overall stability. At the same time, the pedal 74 is used to reinforce and support the stabilizing legs 72, making the stabilizing legs 72 have high strength and not easy to bend or deform. It is also possible to step on the pedal 74 to facilitate firefighters to enter the protective housing 1. When the protective housing 1 rolls to near the fire source, the fire extinguishing device 33 on the side of the outer surface of the protective housing 1 close to the fire source is directly in front of the fire door. At this time, the firefighter connects the outlet end of the fire extinguisher to the inlet of the medium spray tube 331. Under the top pressure of the outlet end of the fire extinguisher, the pressure-receiving teeth 3324 apply the top pressure to the spherical head rod 3323. At this time, the blocking block 3322 is pushed, compressing the elastic rod 3321, and the extinguishing medium is sprayed out and extinguished through the delivery of the medium spray tube 331. Moreover, the other elastic rods 3321 on the outer surface of the protective housing 1 are not compressed, and at this time, the other medium spray tubes 331 are still blocked, making the floating smoke not easy to enter the interior of the protective housing 1, reducing the harm to firefighters. At the same time, using the pressure of the fire extinguisher spraying out the extinguishing medium, the rotating wheel 334 drives the spiral blade 335 to rotate at a high speed, making the sprayed medium receive a swirl, and then spraying the medium a long distance, so that the protective housing 1 can be a little farther away from the fire source to ensure safety. When the protective housing 1 stops rolling, the bottom end of the medium spray tube 331 at the bottom of the protective housing 1 contacts the ground, and thus receives an upward driving force. The other medium spray tubes 331 have no pressure, and using the pressure of the protective housing 1 itself and combined with the elastic force of the curved elastic disk 32, the medium spray tube 331 moves upward, driving the jacking member 34 to move upward, and then applying an upward jacking force to the grab hook 445. Combined with the fact that the sliding rod 442 can be slidably connected to the center of the guide frame 441, the piston disk 444 moves upward smoothly, and then the outer surface of the piston disk 444 is separated from the inner surface of the conical hopper 43, opening the conical hopper 43, allowing the air near the ground to enter the protective housing 1. As the smoke rises, there is very little smoke near the ground, thus ensuring the entry of oxygen into the protective housing 1 to provide oxygen for the firefighters. The other piston disks 444 are not subjected to the pulling force of the grab hook 445 and remain in the blocked state, reducing the entry of smoke.
