Description

Technical Field

[0001] The invention relates to the technical field of outdoor fire fighting, in particular to a modular fire extinguishing capsule. Background Art

[0002] Fire extinguishing capsule is an efficient fire extinguishing tool, especially suitable for extinguishing inaccessible fires such as forest fires. Its main function is to quickly release fire extinguishing substances (such as foam, dry powder or carbon dioxide, etc.) to form a fire extinguishing barrier near the fire source and quickly suppress the spread of fire. This capsule is usually wrapped in a high temperature resistant and impact resistant shell, contains a fire extinguishing agent, and is equipped with a trigger device. The release method of the fire extinguishing capsule is flexible. It can be thrown by hand, airdropped, or quickly delivered to the fire scene by rocket launch. Once it is delivered to the fire source area, the trigger device will automatically activate according to the external temperature change or impact force, release the fire extinguishing agent, cover the fire source and suppress the flame. The rapid release of the fire extinguishing agent can effectively reduce the spread of the fire and buy more time for firefighters to fight the fire; such as a modular multi-purpose fire extinguishing bomb disclosed in the application publication number CN115970194A, including a head assembly, a fire extinguishing bomb body and a tail assembly. The head assembly includes a head cone, a centering part, a gas-locking groove and an assembly interface. The main body of the fire extinguishing bomb includes a shell, an assembly joint, a front centering part, a starter ring, a gas generating agent, a fire extinguishing agent, a rear centering part, a gas blocking groove and an assembly interface. The tail assembly includes an assembly joint, a front weight-reducing hole, a positioning baffle, a tail wing rod, a tail wing and a rear weight-reducing hole. Through different combinations of the head assembly, the main body of the fire extinguishing bomb and the tail assembly, a variety of fire extinguishing bombs such as window-breaking bombs, fire extinguishing bombs and window-breaking fire extinguishing bombs can be formed. By selecting the number of assembled fire extinguishing bomb bodies, fire extinguishing bombs loaded with different amounts of fire extinguishing agents can be effectively adjusted and obtained, thereby obtaining different fire extinguishing ranges and fire extinguishing effects. However, the above technical solution still needs to be used manually or launched using a thrower during use. At the scene of a large-scale fire, the actions of firefighters are restricted by the fire, terrain and climatic conditions. Manual delivery or use of launching equipment may be restricted or delayed. Secondly, manual delivery requires a certain degree of accuracy. If the capsule is not accurately delivered to the key area of ​​the fire source, it may affect the fire extinguishing effect. Once the fire extinguishing capsule is thrown into the fire scene, even if the fire source is not completely extinguished, the remaining fire extinguishing agent cannot be used again. Although this one-time use method can be quick and effective in extinguishing the fire source in the early stage, if the fire spreads, firefighters may need to continuously deliver new fire extinguishing capsules, resulting in higher consumption costs. Summary of the invention

[0003] The object of the present invention is to provide a modular fire extinguishing capsule, in which two fire extinguishing capsule bodies filled with liquid carbon dioxide form a symmetrical structure through a clamp body and are installed on a forest tree through the clamp body. When a fire occurs there, the glass tube of the fire sprinkler at the bottom of the fire extinguishing capsule body is shattered due to the expansion of the heat-sensitive liquid, and the fire extinguishing capsule body is connected to the outside atmosphere, then the liquid carbon dioxide inside the capsule is gasified and quickly sprayed out through the fire sprinkler, so as to solve the problems raised in the above-mentioned background technology.

[0004] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a modular fire extinguishing capsule, comprising a clamp body and dovetail arms integrally formed on the left and right outer walls of the clamp body, a fire extinguishing capsule body filled with liquid carbon dioxide being installed on the outer wall of the dovetail arm away from the clamp body, a one-way valve for filling liquid carbon dioxide being installed at the top of the fire extinguishing capsule body, and a fire sprinkler being installed at the bottom of the fire extinguishing capsule body.

[0005] Preferably, the clamp body is composed of a left clamp half and a right clamp half which are bolted to each other.

[0006] Preferably, both ends of the left half clamp and the right half clamp are integrally formed with connecting ears, and the left half clamp and the right half clamp are bolted together by connecting ears, bolts and nuts.

[0007] Preferably, rubber pads are bonded to the inner walls of the left half clamp and the right half clamp.

[0008] Preferably, a steel sleeve is fixed to one end of the surface of the fire extinguishing capsule body, and the steel sleeve and the dovetail arm are welded to each other.

[0009] Preferably, an arc-shaped groove is provided on the outer wall of one side of the dovetail-shaped arm close to the fire-extinguishing capsule body, and the curvature of the arc-shaped groove is equal to the curvature of the steel sleeve.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows: the modular fire extinguishing capsule is installed on the forest trees through a specially designed clamp body. When the temperature of the fire source rises, the glass tube at the bottom of the fire extinguishing capsule will expand and rupture due to the temperature rise, so that the liquid carbon dioxide inside the capsule contacts with the outside air, gasifies and is sprayed out through the nozzle. This automatic triggering mechanism makes the fire extinguishing process more intelligent and does not rely on manual intervention, greatly reducing the risk of firefighters and improving the fire extinguishing response speed.

[0011] The hoop body is installed on trees or other fixed positions in the forest, without manual throwing or launching. It can stay in the forest continuously, ready to take effect immediately once a fire occurs. This arrangement provides great convenience for the prevention and emergency extinguishing of forest fires, especially in complex forest environments. The fire-extinguishing capsule is no longer limited by the accuracy of throwing or the accessibility of the terrain, and can be on standby around the clock. The used capsule can also be recycled and liquid carbon dioxide can be re-injected into the capsule through a one-way valve for continued use.

[0012] Liquid carbon dioxide can quickly occupy a large amount of space when it is gasified, and because carbon dioxide itself has a suffocating effect, it can effectively reduce the oxygen concentration in the fire source area and quickly extinguish the fire source, thus playing an important role in the early stage of the fire, curbing the spread of the fire from the source and buying precious time for subsequent large-scale fire fighting work; BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-5, an embodiment provided by the present invention: a modular fire extinguishing capsule, comprising a clamp body 1 and a dovetail arm 3 integrally formed on the left and right outer walls of the clamp body 1, a fire extinguishing capsule body 2 filled with liquid carbon dioxide is installed on the outer wall of the dovetail arm 3 away from the clamp body 1, a one-way valve 4 for filling liquid carbon dioxide is installed on the top of the fire extinguishing capsule body 2, and a fire sprinkler 5 is installed on the bottom of the fire extinguishing capsule body 2. The fire sprinkler 5 quickly sprays the gasified carbon dioxide around the fire source to form a fire extinguishing barrier. The suffocation effect of carbon dioxide will quickly reduce the oxygen concentration in the fire source area, thereby extinguishing the fire source and preventing the fire from spreading;

[0021] When the fire extinguishing capsule is recovered later, the staff can refill the interior of the fire extinguishing capsule body 2 with liquid carbon dioxide through the one-way valve 4 and replace the fire sprinkler 5 so that the fire extinguishing capsule body 2 can be put back into the forest for continued use; the one-way valve 4 controls the flow direction of the liquid carbon dioxide and ensures that there will be no reverse flow during the fire extinguishing process.

[0022] The clamp body 1 is composed of a left clamp 101 and a right clamp 102 which are bolted to each other. The left clamp 101 and the right clamp 102 are made of high-strength, corrosion-resistant stainless steel materials and can withstand extreme weather and environmental changes. The left clamp 101 and the right clamp 102 are integrally formed with connecting ears 103 at both ends. The left clamp 101 and the right clamp 102 are bolted by connecting ears 103, bolts and nuts. Rubber pads 6 are bonded to the inner walls of the left clamp 101 and the right clamp 102. The left clamp 101 and the right clamp 102 embrace the forest trees, and the left clamp 101 and the right clamp 102 are connected by connecting ears 103 and bolts, so that the fire extinguishing capsule body 2 is firmly tied to the trees to ensure that it can work stably when a fire occurs.

[0023] A steel sleeve 201 is fixed to one end of the surface of the fire extinguishing capsule body 2, and the steel sleeve 201 and the dovetail arm 3 are welded to each other. An arc groove 301 is provided on the outer wall of the dovetail arm 3 close to the fire extinguishing capsule body 2, and the curvature of the arc groove 301 is equal to that of the steel sleeve 201;

[0024] A steel sleeve 201 is installed on the outer peripheral surface of the fire extinguishing capsule body 2, and the fire extinguishing capsule body 2 is welded to the dovetail arm 3 through the steel sleeve 201, so that the fire extinguishing capsule body 2 and the left half clamp 101 or the fire extinguishing capsule body 2 and the right half clamp 102 form an integral structure, which is convenient for staff to quickly assemble the device on site for use.

[0025] When the embodiment of the present application is in use, the fire extinguishing capsule body 2 is first firmly installed on a tree or other suitable structure through the clamp body 1 to ensure that the fire extinguishing capsule body 2 can work normally when a fire occurs. When the temperature of the fire source rises, the glass tube of the fire sprinkler head 5 at the bottom of the fire extinguishing capsule body 2 breaks due to the expansion change of the heat-sensitive liquid, triggering the release of liquid carbon dioxide inside the capsule. The liquid carbon dioxide is quickly guided to the fire sprinkler head 5, and the fire sprinkler head 5 vaporizes the carbon dioxide and sprays it into the fire source area, rapidly reducing the oxygen concentration of the fire source and suppressing the fire. The gasification of carbon dioxide reduces the oxygen concentration in the fire source area, thereby achieving the effect of quickly extinguishing the fire source.
