[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 As shown, a fine water mist isolation and rescue device for fire fighting includes a mobile frame 1, universal wheels are fixedly installed at the four corners of the lower end of the mobile frame 1, a frame 5 is fixedly installed at the upper edge of the mobile frame 1, water mist spraying assemblies 2 are fixedly installed on the left and right sides and front side of the frame 5, a range adjustment assembly 3 is fixedly installed on the left rear side of the frame 5, and a cooling protection assembly 4 is fixedly installed on the upper rear end of the frame 5.

[0026] The water mist spray assembly 2 sprays water mist in front of and to the left and right of the frame 5 as the device advances, forming a water mist curtain that isolates and extinguishes the fire. The range adjustment assembly 3 increases the spray range of the two side pipes 25 and one intercepting pipe 28, increasing the area of ​​the water mist dispersion while ensuring a continuous flow of mist into the air, further protecting personnel within the moving frame 1. The cooling protection assembly 4 sprays water mist back and forth between the two isolation panels 51, ensuring surface moisture retention for rescued personnel and preventing the high temperature at the fire scene from impacting evacuation, thereby enhancing the safety of the device itself.

[0027] like Figure 3 and Figure 4 As shown, the water mist spraying assembly 2 includes a water tank 21 to which water can be added. The lower end of the water tank 21 is fixedly installed on the front upper end of the movable frame 1. A high-pressure water pump 22 is fixedly installed on the middle upper end of the water tank 21. An atomizer 23 is fixedly installed on the output end of the high-pressure water pump 22. Side hoses 24 are fixedly installed on the left and right parts of the output end of the atomizer 23. The tops of the left and right sides of the frame 5 are rotatably connected to side tubes 25. The ends of the two side hoses 24 away from the atomizer 23 are fixedly connected to the front position of the bottom of the outer wall of the two side tubes 25.

[0028] After water is added to the water tank 21, the mobile frame 1 moves into the fire site through four universal wheels. The high-pressure water pump 22 is an existing mechanism, which can pump the water in the water tank 21 into the atomizer 23. The atomizer 23 processes the water flow to form a fine water mist. The fine water mist enters the two side pipes 25 through two side hoses 24. The two side pipes 25 spray mist on the left and right sides of the frame 5 through several spray heads 26.

[0029] like Figure 4 As shown, a front hose 27 is fixedly installed on the top of the output end of the atomizer 23, and an interception tube 28 is rotatably connected to the top of the front side of the frame 5. The end of the front hose 27 away from the atomizer 23 is fixedly connected to the middle position of the bottom of the outer wall of the interception tube 28, and a plurality of linearly arranged spray heads 26 are fixedly installed on the side of the outer walls of the two side tubes 25 away from each other and the front of the outer wall of the interception tube 28.

[0030] When working, the atomizer 23 also inputs fine water mist into the front hose 27, and the front hose 27 transmits the fine water mist to the interception pipe 28. The interception pipe 28 can intercept and extinguish the flame in front of the frame 5 when spraying mist through several spray heads 26.

[0031] like Figure 4 As shown, the range adjustment assembly 3 includes a protective cover 31, the front side of the protective cover 31 is fixedly installed at the left position of the top rear side of the frame 5, an electric push rod 32 is fixedly installed on the left part of the inner cavity of the protective cover 31, a rack 33 is fixedly installed on the output end of the electric push rod 32, a slide bar 34 is fixedly installed on the right part of the inner cavity of the protective cover 31, and the inner wall of the middle right side of the rack 33 is slidably connected to the outer wall of the slide bar 34.

[0032] The protective cover 31 is used to protect the safety of the electrical structure. When the electric push rod 32 is started, it can drive the rack 33 to slide on the slide bar 34.

[0033] like Figure 4 As shown, a gear 35 is fixedly connected to the rear portion of the outer wall of the left side tube 25, and the outer surface of the gear 35 is engaged with the left side of the rack 33. A bevel gear 1 36 is fixedly connected to the front portion of the outer wall of the two side tubes 25, and a bevel gear 2 37 is fixedly connected to the left and right portions of the outer wall of the intercepting tube 28, and the outer surfaces of the two bevel gears 1 36 are engaged with the outer surfaces of the two bevel gears 2 37.

[0034] The gear 35 drives the left side pipe 25 to rotate by meshing with the rack 33. The two side pipes 25 and the intercepting pipe 28 rotate synchronously by meshing with the corresponding bevel gear 1 36 and the bevel gear 2 37. When the three pipes rotate, the spray range of the several spray heads 26 will be increased, so that the fine water mist always spreads around the frame 5, maintaining the stability of the environment in this area.

[0035] like Figure 5 As shown, the cooling protection component 4 includes a turntable 41, the lower end of the turntable 41 is rotatably connected to the rear part of the upper end of the frame 5, and a motor box 42 is fixedly installed at the rear position of the top of the inner wall of the frame 5. The output end of the motor box 42 is fixedly connected to the lower end of the turntable 41, and a rotating rod 43 is rotatably connected to the upper edge of the turntable 41. Limit rods 44 are fixedly installed on the left and right parts of the upper end of the frame 5, and the outer walls of the two limit rods 44 are slidably connected to a movable plate 45. The end of the rotating rod 43 away from the turntable 41 is rotatably connected to the middle part of the rear side of the movable plate 45.

[0036] The motor box 42 has the same function as the motor. Its output end can drive the turntable 41 to rotate, so that the rotating rod 43 pulls and pushes the moving plate 45 to move back and forth on the two limit rods 44 due to the rotation of the turntable 41.

[0037] like Figure 5As shown, a top pipe 46 is fixedly installed at the lower end of the movable plate 45, and a plurality of cooling nozzles are fixedly installed at the bottom of the outer wall of the top pipe 46. A connecting hose 47 is fixedly installed at the rear of the output end of the atomizer 23, and the end of the connecting hose 47 away from the atomizer 23 is fixedly connected to the middle position of the front part of the outer wall of the top pipe 46.

[0038] When the movable plate 45 moves, it can drive the top pipe 46 to move back and forth. The top pipe 46 sprays the fine water mist delivered by the connecting hose 47 onto the surface of the personnel through a plurality of cooling nozzles, thereby playing a cooling and protective role.

[0039] like Figure 2 As shown, isolation plates 51 are fixedly installed on the left and right parts of the inner wall of the frame 5, and a plurality of air holes 52 are opened on the side away from each other of the two isolation plates 51, and through holes matching the two side hoses 24 are opened on the front part of the side away from each other of the two isolation plates 51.

[0040] When the device is working, personnel can be located between the two isolation plates 51 to isolate the high temperature and flames at the fire scene.

[0041] The working principle of the present utility model is as follows: After water is added to the water tank 21, the mobile frame 1 is moved into the fire site via four universal wheels. The rescued personnel are generally positioned between two isolation panels 51. The high-pressure water pump 22 pumps the water in the water tank 21 into the atomizer 23. The atomizer 23 processes the water flow into a fine water mist. The fine water mist enters the two side pipes 25 through two side hoses 24. The two side pipes 25 spray the mist to the left and right sides of the frame 5 through a plurality of spray heads 26. When the atomizer 23 is in operation, the fine water mist is also input into the front hose 27. The front hose 27 transmits the fine water mist to the interception pipe 28. The interception pipe 28, when sprayed with mist by the plurality of spray heads 26, can intercept and extinguish the flames in front of the frame 5.

[0042] At the same time, the output end of the electric push rod 32 begins to extend and retract, causing the rack 33 to slide on the slide rod 34. The gear 35 drives the left side tube 25 to rotate by engaging with the rack 33. The two side tubes 25 and an intercepting tube 28 rotate synchronously through the engagement of the corresponding bevel gear 1 36 and the bevel gear 2 37. When the three pipes rotate, the spray range of several spray heads 26 will be increased, so that the fine water mist is always diffused around the frame 5, maintaining the stability of the environment in this area.

[0043] Simultaneously, the output end of motor box 42 drives turntable 41 to rotate, causing rotating rod 43 to pull and push movable plate 45 to reciprocate on two limit rods 44. The movement of movable plate 45 drives top pipe 46 to reciprocate. Top pipe 46 sprays a fine water mist delivered by connecting hose 47 onto the user's body surface through a number of cooling nozzles, providing cooling protection.

[0044] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention.
