In view of this, the utility model proposes an isolation frame for grassland fire prevention. Utility Model Content

[0030] Example
[0031] like Figure 1 As shown, the utility model proposes an isolation frame for grassland fire prevention, including an isolation frame 1, and multiple groups of base frames 11 installed at the bottom thereof for support. A fixing plate 12 is also installed in the middle position of the isolation frame 1. The isolation frame 1 is easy to place and can be placed directly on the grass.
[0032] For details, please refer to Figure 1-4The above-mentioned isolation frame includes a fire extinguishing isolation assembly 2 installed on the isolation frame 1 for spraying carbon dioxide gas and foam fire extinguishing agent for fire extinguishing. The fire extinguishing isolation assembly 2 includes a high-pressure gas tank 21, a first discharge pipe 22, and a connection box 23. The high-pressure gas tank 21 is installed in the isolation frame 1. Liquid carbon dioxide is stored in the high-pressure gas tank 21. After the high-pressure gas tank 21 is connected to the outside, it sprays carbon dioxide gas to extinguish the fire. One end of the first discharge pipe 22 is connected to the top of the high-pressure gas tank 21. The connection box 23 installed in the hollow on one side of the fixed plate 12 close to the high-pressure gas tank 21 is connected to the other end of the first discharge pipe 22. The carbon dioxide gas in the high-pressure gas tank 21 enters the connection box 23 through the first discharge pipe 22. The fire extinguishing isolation assembly 2 also includes a connection pipe 24, a discharge box 25, and a spray pipe 26. The connection pipe 24 rotatably connected to the fixed plate 12 through a bearing is rotatably connected to the connection box 23, and the connection pipe 24 remains in place and rotates. The discharge box 25 is fixedly connected to the end of the connecting pipe 24 away from the connecting box 23. The discharge box 25 is also hollow. The arc-shaped multiple groups of spray pipes 26 are distributed in a ring array on the outer circle of the discharge box 25. After the carbon dioxide enters the discharge box 25, it is discharged through the multiple groups of spray pipes 26, and the discharge box 25 and the spray pipes 26 start to rotate. The fire extinguishing isolation assembly 2 also includes a liquid storage tank 27 and a second discharge pipe 28. The liquid storage tank 27 installed on the isolation frame 1 stores foam fire extinguishing agent, which is driven by high-speed carbon dioxide and sprayed out at the same time, which can cool the combustion surface, reduce the flame temperature, and reduce the possibility of fire spreading. One end of the second discharge pipe 28 is connected to the side of the liquid storage tank 27, and the other end of the second discharge pipe 28 is connected to the first discharge pipe 22 through a three-way connection, so that when the carbon dioxide passes through the first discharge pipe 22 at a high speed, the foam fire extinguishing agent in the liquid storage tank 27 is driven to be sprayed out synchronously through the second discharge pipe 28. The fire extinguishing isolation assembly 2 also includes an arc plate 29 arranged above the multiple groups of spray pipes 26. The arc plate 29 is installed on the side of the isolation frame 1, so that the carbon dioxide and foam fire extinguishing agent sprayed upward are guided by the arc plate 29 to spray toward the fire source, which is convenient for fire extinguishing.
[0033] Further, such as Figure 5As shown, the isolation frame also includes a response mechanism 3 for controlling the automatic opening of the fire extinguishing isolation assembly 2 when the flame approaches. The response mechanism 3 includes a valve 31, a gear 32, a rack 33, a fixed block 34, a connecting rod 35, and a connecting block 36. The valve 31 is installed on the first discharge pipe 22. The valve 31 controls whether the carbon dioxide gas in the high-pressure gas cylinder 21 is discharged when it is switched. The valve stem of the valve 31 passes through the fixed plate 12 and is fixedly connected to the gear 32. The gear 32 drives the valve 31 to open when it rotates. The rack 33 is arranged on one side of the gear 32 and meshes with it. The rack 33 drives the gear 32 to rotate when it moves. Two sets of fixed blocks 34 are installed on the side of the rack 33 away from the gear 32. The fixed blocks 34 move synchronously with the rack 33. The connecting rod 35 is fixedly connected with two groups of fixed blocks 34. The connecting rod 35 is inserted into a group of fixed blocks 34 below. The connecting rod 35 moves synchronously with the rack 33 and the fixed block 34. The connecting rod 35 is set in a quadrangular prism shape so that it is stable when moving. The connecting block 36 fixedly connected to the side of the isolation frame 1 is fixedly connected to the bottom of the connecting rod 35. The connecting block 36 is made of tin material, which is used for the connecting block 36 to melt quickly after being burned by fire so that the spring 39 can release the elastic force. The response mechanism 3 also includes a mounting plate 37, a fixing seat 38, and a spring 39. The mounting plate 37 is fixedly connected between the isolation frame 1 and the fixing plate 12. The two groups of fixing seats 38 are slidably connected to the connecting rod 35. One group of fixing seats 38 is located between the two groups of fixing blocks 34 and is fixedly connected to the side of the fixing plate 12. The other group of fixing seats 38 is located below the group of fixing blocks 34 below and is fixedly connected to the side of the mounting plate 37. The positions of the two groups of fixing seats 38 are fixed, so as to limit the movement of the connecting rod 35. The spring 39 is arranged between a lower set of fixing blocks 34 and a lower set of fixing seats 38. The spring 39 is in a compressed state and is used to release elastic force to drive the rack 33 to move upward after the connecting block 36 melts, so that the gear 32 rotates to drive the valve 31 to open so that carbon dioxide is sprayed out for fire extinguishing and isolation.
[0034] In this embodiment, the isolation frame 1 is directly placed on the grassland, and the isolation frame 1 is placed stably by the base frame 11. When a fire occurs, as the fire spreads, the flames burn the connecting block 36, and the connecting block 36 can melt quickly. Therefore, the spring 39 releases the elastic force, squeezes the lower set of fixed blocks 34 to move upward, and at this time, the two sets of fixed blocks 34 move synchronously with the connecting rod 35, and move upward steadily under the limiting effect of the fixed seat 38. The rack 33 moves upward at the same time and meshes with the gear 32 to drive the gear 32 to rotate. When the gear 32 rotates, it drives the valve 31 to rotate and open, so that the carbon dioxide in the high-pressure gas tank 21 is ejected at high speed through the first discharge pipe 22 and enters the connection box 23. At the same time, when the gas passes at high speed, it drives the foam fire extinguishing agent in the liquid storage tank 27 to be ejected at the same time, so that after the carbon dioxide mixed with the foam fire extinguishing agent enters the connection box 23, it enters the discharge box 25 through the connecting pipe 24 and is ejected by multiple groups of arc-shaped spray pipes 26. At this time, the discharge box 25 and the spray pipe 26 start to rotate under the limiting effect of the connecting pipe 24. Carbon dioxide and foam fire extinguishing agent are sprayed around the discharge box 25. Due to the fast spraying speed, the spraying distance to both sides is far, with a large isolation width. This prevents the fire from continuing to spread and causing greater damage. The carbon dioxide and foam fire extinguishing agent sprayed upward are guided to spray near the fire source after contacting the arc plate 29, thereby improving the fire extinguishing effect.
[0035] The above specific embodiment is only an optional embodiment of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above embodiment, those skilled in the art can make various alternative improvements and combinations to the above specific embodiment.
