AI Technical Summary
Existing fire extinguishing devices may cause fire extinguishing lag in the early stages of a fire, missing the best time to extinguish fire, aggravating the development of fire situations. Especially in unattended or special environments, traditional fixed fire extinguishing systems cannot achieve all-round and instant protection without dead corners.
A self-excited flame-destroying tank is designed, including a fixed groove, a flame-destroying layer and a temperature-sensitive layer. The flame-killing layer is composed of flame-killing microcapsules wrapped in hot melt adhesive. A heat conduction wire is installed in the temperature sensing layer. When the object is covered by a groove, the temperature-killing layer senses the temperature and conducts heat to the flame-killing layer. After the hot melt adhesive reaches the predetermined temperature, it dissolves the flame-killing microcapsules to extinguish the fire.
It realizes rapid response and precise fire extinguishing in the early stages of a fire, avoids fire extinguishing lag, effectively prevents the development of fire conditions, and provides comprehensive and blind spot protection in special environments.

Abstract
Description
Technical Field
[0001] The utility model belongs to the field of flame extinguishing grooves, and in particular relates to a self-excitation type flame extinguishing groove. Background Art
[0002] In daily life, industrial production and various commercial activities, fire accidents are often sudden and unpredictable, posing a serious threat to personal safety, property value and even the ecological environment. With the improvement of material living standards and the advancement of technology, the items people use are becoming increasingly rich and diverse, including a large number of combustible and flammable materials, such as furniture, electrical appliances, chemicals, paper documents, fuel storage facilities, etc. Once these items encounter a fire source, the fire is likely to spread rapidly, especially when there is no one on duty or the initial discovery is not timely. The fire will often evolve from a local disaster to a large-scale disaster. If the fire is not extinguished in time, the losses caused will be huge.
[0003] Although existing fire prevention measures have achieved remarkable results, they still have certain limitations, especially in terms of rapid response and precise fire extinguishing. Traditional manual fire extinguishing methods rely on timely detection and effective intervention by people. In the early stages of a fire, especially at night or in unmanned areas, this dependence may lead to delayed fire extinguishing, thus missing the best time to put out fires and exacerbating the development of the fire. In addition, in many specific occasions, such as laboratories, libraries, computer rooms, and storage places, due to their special internal environment and the presence of a large number of flammable materials, conventional fixed fire extinguishing systems sometimes cannot provide all-round, no-dead-angle immediate protection.
[0004] Based on this, the utility model proposes a self-excitation type flame extinguishing tank. Utility Model Content
[0005] In order to solve the above-mentioned problem in the prior art, that is, the fire extinguishing device in the prior art may cause a delay in fire extinguishing, thereby missing the best time to extinguish fire and aggravating the development of the fire, the utility model provides a self-excitation type flame extinguishing groove, including a groove, a flame extinguishing layer and a temperature sensing layer fixed in sequence;
[0006] The groove is used for covering objects, the flame extinguishing layer comprises a plurality of flame extinguishing microcapsules wrapped by hot melt adhesive, the flame extinguishing microcapsules are provided with fire extinguishing agent, and the temperature sensing layer is provided with heat conducting wires for transferring heat.
[0007] In some preferred embodiments, the cross-sectional shape of the groove includes a U shape.
[0008] In some preferred embodiments, the cross-sectional shape of the groove includes a ∩ shape.
[0009] In some preferred embodiments, the cross-sectional shape of the flame extinguishing layer and the temperature sensitive layer is the same as the cross-sectional shape of the groove.
[0010] In some preferred embodiments, the shape of the thermal conductive wire includes a wave shape.
[0011] In some preferred embodiments, the fire extinguishing agent is perfluorohexanone or heptafluoropropane or IG541 or aerosol.
[0012] In some preferred embodiments, the activation temperature of the flame-extinguishing microcapsules is 80°C to 120°C, and the dissolution temperature of the hot melt adhesive is 70°C to 80°C.
[0013] In some preferred embodiments, the thermally conductive wire material includes thermally conductive metal or fiber.
[0014] In some preferred embodiments, the material of the groove includes flame retardant plastic or metal material.
[0015] In some preferred embodiments, a cover plate is further included, and the cover plate is installed at the opening of the groove to form a square shape.
[0016] Beneficial effects of the utility model:
[0017] By arranging a flame extinguishing layer and a temperature-sensitive layer in the groove, when an object is placed in the groove or covered by the groove, the temperature-sensitive layer can sensitively sense the temperature and transmit the temperature to the flame extinguishing layer. The hot melt adhesive in the flame extinguishing layer will dissolve when the predetermined temperature is reached to release the flame extinguishing microcapsules. At the same time, the structure of the flame extinguishing microcapsules will not be destroyed in advance, and no harmful substances will be released after use. When a fire occurs, the flame extinguishing microcapsules in the flame extinguishing layer can be released more quickly to extinguish the fire. BRIEF DESCRIPTION OF THE DRAWINGS
