Description

Technical Field

[0001] The utility model relates to the field of active fire extinguishing devices, in particular to a fixed active fire extinguishing device. Background Art

[0002] For fires caused by short circuits or switch failures in the distribution box, a fixed active fire extinguishing device can be used to extinguish the fire better and faster when the fire first occurs, preventing a larger fire from occurring due to unnoticed conditions. It can also avoid the situation where the fire is not put out in time due to forgetting to turn off the power.

[0003] Existing dry powder fire extinguishers leave behind a large amount of dust after each fire, which is very harmful to electrical equipment. Not only is it difficult to clean, it can also easily cause electrical leakage, which is a major challenge for subsequent cleanup. Water-based fire extinguishing devices use water as the main fire extinguishing medium, which is even more difficult to use directly on electrical equipment. Aerosol fire extinguishing devices can also be used on electrical equipment, but they may produce harmful residues during the release process, posing a potential threat to humans and the environment. These residues, including carbonate and metal oxide particles, are difficult to settle and may damage equipment. Therefore, fixed active fire extinguishing devices are proposed to address this problem. Utility Model Content

[0033] Specifically, in this embodiment, a plurality of ellipsoids 2 are provided on the surface of the working surface 1. The interior of the ellipsoid 2 is hollow, and a plurality of ellipsoids 2 of gradually smaller sizes are stacked together, and the space between the two ellipsoids 2 is filled with fire extinguishing materials. Because the ellipsoid 2 can melt and release the fire extinguishing materials when encountering fire, when the fire is controlled, the inner ellipsoid 2 is preserved. An iron sheet 8 is fixed inside the ellipsoid 2, which can be adsorbed together with the magnetic suction cup 5 below. The rotating shaft 6 at the bottom center of the magnetic suction cup 5 can make the working surface 1 rotate to any angle. A fixed seat 7 is rotatably connected to the outside of the rotating shaft 6, and a support rod 4 is rotatably connected to the bottom of the fixed seat 7. The support rod 4 is retractable. A circular shaft 11 passes through the bottom of the support rod 4 and is fixed inside the two rotating pieces 10. At this time, the working surface 1 can stay at any position.

[0034] Reference Figure 1 - Figure 3 The fixed component includes a card box 9, the bottom of which is fixedly connected to the top of the base 3, and two limit columns 14 are fixedly connected to the inside of the card box 9, wherein the outer side of one limit column 14 is slidably connected to a button 12, and a spring 13 is sleeved on the outer side of the limit column 14, and the outer side of the other limit column 14 is slidably connected to a slider 17, and the rear end of the slider 17 is fixedly connected to a latch 16, and a rotating rod 15 is provided between the latch 16 and the button 12, and the outer side of the button 12 is slidably connected to the inside of the card box 9, the top of the spring 13 is fixedly connected to the bottom of the button 12, and the bottom of the spring 13 is fixedly connected to the inner bottom wall of the card box 9, the left end of the rotating rod 15 is rotatably connected to the top of the latch 16, and the right end of the rotating rod 15 is rotatably connected to the left end of the button 12.

Depending on the fire situation, if the fire is controlled, the inner ellipsoid 2 will not melt and the fire extinguishing substances will not be released again. If the fire is not extinguished, the inner ellipsoid 2 will melt again to release the fire extinguishing substances. Because there are multiple layers of ellipsoids 2 nested, the fire extinguishing device in this embodiment can be reused many times. An iron sheet 8 is provided inside the working surface 1, and a magnetic suction cup 5 is provided under the working surface 1. The working surface 1 and the magnetic suction cup 5 can be fixed together by magnetic force. The working surface 1 can be rotated by using the rotating shaft 6 and the fixing seat 7. The working surface 1 can be rotated to the desired angle through the support rod 4 and the rotating piece 10. Through the fixing component provided on the surface of the base 3, only the button 12 needs to be pressed, and the button 12 can rotate the rotating rod 15 and pull the limit column 14. When the base 3 needs to be fixed on a vertical plane, only the button 12 needs to be released. Under the action of the spring 13, the limit column 14 finally penetrates the base 3 and is inserted into the preset hole.
