Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguishing devices, in particular to a grassland fire prevention and extinguishing device. Background Art

[0002] Grassland fire prevention and extinguishing equipment is a device used to prevent and control grassland fires. It usually includes a series of technologies and measures to reduce the probability of fire, respond to fires in a timely manner, and minimize the damage to the environment and human life and property caused by fires. Backpack fire extinguishing equipment is a portable fire extinguishing device that is usually carried by firefighters for firefighting operations. This device is suitable for complex terrains such as grasslands and forests that are not convenient for large machinery to enter. Especially in the early stages of grassland fires, backpack fire extinguishing equipment can respond quickly and control the fire in time.

[0003] Fires on grasslands are more likely to produce large amounts of dust than fires in urban housing areas. This is due to the difference in the combustion medium, and because grassland fires usually involve large areas of vegetation, the fire spreads quickly, the burning material is large, and the soil moisture in grassland areas is usually high, and the evaporation of water during the combustion process will produce more smoke and dust. The grass ash produced by the burning will be scattered everywhere due to the wind and the direction of the fire spread. These grass ashes will float in front of the firefighters' faces, not only blocking the firefighters' sight but also causing discomfort to their eyes. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0026] Example

[0027] like Figure 1-2 As shown, a grassland fire prevention and extinguishing device proposed by the utility model comprises a base 1, a water tank 2 and a gas cylinder 201 on the base 1 are fixedly mounted on the base 1, and an aerosol sprayer 202 is detachably mounted on the base 1. The water tank 2 is used for water for extinguishing fires. Water is a commonly used fire extinguishing agent, especially suitable for initial fires or flammable liquid fires. The gas cylinder 201 stores compressed air or other gases. These gases are used to drive the spraying of fire extinguishing agents, especially when dry powder or foam fire extinguishing agents are used. Compressed air or gas is released from the gas cylinder 201 and transported to the aerosol sprayer 202 through a pipeline. The aerosol sprayer 202 sprays the fire extinguishing agent in a mist form, which can increase the contact area between the fire extinguishing agent and the burning material and improve the fire extinguishing efficiency. Straps 101 are fixedly mounted on both sides of the base 1, and the two straps 101 are mutually engaged. The straps 101 are convenient for firefighters to carry the device.

[0028] like Figure 2-6 As shown, it also includes: an ash diversion mechanism installed on the base 1, which controls the ash in front of the firefighter to move away from the firefighter. The ash diversion mechanism includes a lower diversion component installed on the base 1 and an upper diversion component installed on the base 1, and an air intake adjustment component is installed on the lower diversion component.

[0029] The base 1 is fixedly provided with a lower support plate 3, and the lower flow guide component includes a lower wind box 4 fixedly provided on the lower support plate 3, a lower wind unit 401 is fixedly provided in the lower wind box 4, lower air holes 402 are provided on both upper and lower sides of the lower wind box 4, a lower flow guide sleeve 403 is fixedly provided on the lower wind box 4, and the lower flow guide sleeve 403 is connected with the lower wind box 4. When the lower wind unit 401 is started, the external air can enter the lower wind box 4 through the lower air holes 402, and the air can enter the lower flow guide sleeve 403, and the air can be blown out after being guided by the lower flow guide sleeve 403.

[0030] Among them, the air intake adjustment component includes an air intake box 404 fixedly installed on the lower air box 4, the air intake box 404 is connected to the lower air box 4, a partition plate 409 is fixedly installed in the air intake box 404, the partition plate 409 separates the air intake box 404 into two parts, two groups of air intake holes 405 are provided on the partition plate 409, a sealing plate 408 is slidably installed on the partition plate 409, an electric push rod 407 is fixedly installed in the air intake box 404, the telescopic axis of the electric push rod 407 is fixedly connected to the sealing plate 408, two filters 406 are fixedly installed in the air intake box 404, the two filters 406 are located on both sides of the partition plate 409, the two groups of air intake holes 405 correspond one by one to the two filters 406, and the air intake holes 405 are located above the filters 406. The downwind unit 401 will generate suction to the external gas through the filter 406, and the filter 406 will intercept the external dust and grass ash to prevent more grass ash from being blown in front of the firefighters. By blocking the air inlet 405 with the sealing plate 408, only one filter 406 can generate suction to the outside at the same time. The position of the sealing plate 408 can be controlled by the electric push rod 407 to control the sealing plate 408 to block any group of air inlet holes 405. The filter 406 corresponding to the blocked air inlet holes 405 will not generate suction to the outside. At this time, as the firefighters move, the filter 406 can be driven to vibrate slightly, so that the grass leaves and grass ash contaminated on the filter can be separated from the filter 406. The position of the sealing plate 408 can be periodically switched to periodically enable the two filters to prevent the grass leaves from blocking the filter and avoid a reduction in the air intake.

[0031] Among them, the upper support plate 5 is fixedly mounted on the base 1, and the upper guide component includes an upper wind box 6 fixedly mounted on the upper support plate 5, an upper wind unit 601 is fixedly mounted in the upper wind box 6, upper air holes 602 are arranged on both sides of the upper wind box 6, an upper guide sleeve 603 is fixedly mounted on the upper wind box 6, and the upper guide sleeve 603 is connected to the upper wind box 6. Starting the upper wind unit 601 can make the upper guide sleeve 603 generate suction to the outside world, and the gas enters the upper wind box 6, and then is discharged through the upper air holes 602.

[0032] Furthermore, the calibers of the lower guide sleeve 403 and the upper guide sleeve 603 are gradually reduced, and the ends with smaller calibers of the lower guide sleeve 403 and the upper guide sleeve 603 correspond to each other. Thereby, the gas blown out by the downwind unit 401 can be sucked into the upwind unit 601, and through the arrangement of the upper guide sleeve 603 and the lower guide sleeve 403, the linearity of the gas blown out by the downwind unit 401 and the gas sucked in by the upwind unit can be improved to prevent the gas from spreading everywhere. Through the cooperation between the downwind unit 401 and the upwind unit 601, a wind wall can be formed between the upper guide sleeve 603 and the lower guide sleeve 403. Since the gas flow rate between the upper guide sleeve 603 and the lower guide sleeve 403 is relatively fast, and since the gas flow rate here is greater than the gas flow rate on both sides of the wind wall, the air pressure here is greater than the air pressure on both sides, and then the grass ash near the wind wall can be sucked into the wind wall, and then enters the upper bellows 6 and is discharged, thereby preventing dust and grass ash from getting close to the face of the firefighter, preventing the grass ash from staining the face of the firefighter, preventing the eyes of the firefighter from being polluted, and preventing the grass ash from affecting the sight of the firefighter.

[0033] like Figure 7 As shown, the lower guide sleeve 403 and the upper guide sleeve 603 are both fixedly mounted with a telescopic tube 7, and the lower guide sleeve 403 and the upper guide sleeve 603 are both mounted with an adjustment mechanism, and the adjustment mechanism adjusts the length of the telescopic tube 7. The adjustment mechanism includes a connecting block 801 fixedly mounted on the lower guide sleeve 403 or the upper guide sleeve 603, a mounting block 8 fixedly mounted on the telescopic tube 7, and a screw rod 802 rotatably mounted on the mounting block 8, and the screw rod 802 is threadedly connected to the connecting block 801. By rotating the screw rod 802, the distance between the mounting block 8 and the connecting block 801 can be adjusted, and then the telescopic tube 7 can be driven to be extended and retracted, so that the distance between the two telescopic tubes 7 can be adjusted, and can be adjusted autonomously according to actual usage conditions.

[0034] Working principle: the gas blown out by the downwind unit 401 is sucked into the upwind unit 601, and the arrangement of the upper guide sleeve 603 and the lower guide sleeve 403 can improve the linearity of the gas blown out by the downwind unit 401 and the gas sucked in by the upwind unit, and prevent the gas from spreading everywhere. Through the cooperation between the downwind unit 401 and the upwind unit 601, a wind wall can be formed between the upper guide sleeve 603 and the lower guide sleeve 403. Since the gas flow rate between the upper guide sleeve 603 and the lower guide sleeve 403 is relatively fast, and since the gas flow rate here is greater than the gas flow rate on both sides of the wind wall, the air pressure here is greater than the air pressure on both sides, and then the grass ash near the wind wall can be sucked into the wind wall, and then enters the upper bellows 6 and is discharged, thereby preventing dust and grass ash from getting close to the face of the firefighter, preventing the grass ash from staining the face of the firefighter, preventing the firefighter's eyes from being polluted, and preventing the grass ash from affecting the firefighter's line of sight.
