Description

Technical Field

[0001] The present disclosure belongs to the field of fire-fighting equipment, and particularly relates to a fire-extinguishing bomb for remotely hand-throwing and extinguishing crown fires. Background Art

[0002] A fire-extinguishing bomb is a device filled with chemical agents for fire extinguishing. It can be projected into a fire scene. After the outer shell of the bomb body is broken, a large amount of internal flame-retardant chemical agents are sprayed outwards, thus quickly extinguishing the fire. This device is suitable for extinguishing large-area fires in mountain forests, forests, grasslands, etc., and is one of the cutting-edge weapons for large-area forest fire extinguishing.

[0003] For example, a hand-held fire-extinguishing bomb with the application number 201210446858.1 has a fragile circular bomb body. When a fire occurs, the outer shell needs to impact the fire contact surface to break. However, due to the large gaps between the branches in the crown, when the fire-extinguishing bomb is thrown, it will pass through the gaps between the crown branches, making it difficult for the fire-extinguishing bomb to explode on the crown. Utility Model Content

[0004] Aiming at the deficiencies of the prior art, the purpose of the present disclosure is to provide a fire-extinguishing bomb for remotely hand-throwing and extinguishing crown fires, which solves the problem in the prior art that due to the large gaps between the branches in the crown, it is difficult for the fire-extinguishing bomb to collide with the branches, resulting in difficulty in extinguishing the fire for the crown.

[0005] The purpose of the present disclosure can be achieved through the following technical solutions:

[0006] A fire-extinguishing bomb device for remotely hand-throwing and extinguishing crown fires includes: a protective shell and a conical tube. The protective shell includes a first shell and a second shell. The right end of the first shell is coaxially connected to the second shell. And a safety buckle is provided between the first shell and the second shell. The materials of the first shell and the second shell are straight tubular rotational molding materials. Threaded connections are provided at both the left and right ends of the protective shell with handles. And at least one group of conical tubes are coaxially inserted inside the handles. And two groups of handles and conical tubes are symmetrically arranged with respect to the safety buckle.

[0007] In some disclosures, a connection port is fixed on one side of the first shell close to the second shell. And an interface is clamped inside the connection port. The diameter of the connection port is larger than the diameter of the interface.

[0008] In some disclosures, a fixing ring is fixed inside the connection port. And multiple groups of fixing protrusions are arranged around the outside of the interface. And the first shell and the second shell form a communicating structure through the connection port and the interface.

[0009] In some disclosures, threaded protrusions are fixed at both the left and right ends of the protective shell. And a connecting pipe is threadedly connected to the outside of the threaded protrusions.

[0010] In some disclosures, a chute is disposed around the outer side of the handle, and the conical tube moves along the chute.

[0011] In some disclosures, a limiting flap is fixed to the side of the conical tube away from the protective shell, and the diameter of the limiting flap is greater than the diameter of the pipe orifice of the conical tube.

[0012] In some disclosures, a sealing ring is disposed between the connection port and the engagement port.

[0013] In some disclosures, the first housing and the second housing form a sealed structure through the connection port and the engagement port.

[0027] Next, the technical solutions in the embodiments of the present disclosure will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present disclosure.

[0028] According to the concept of the present application, an embodiment of a fire extinguishing bomb for remotely hand-throwing and extinguishing crown fires will be described herein in conjunction with Figures 1 to 5 Specifically, the fire extinguishing bomb is configured as a split structure, which has three components: a protective shell 1, a conical tube 51, and a safety catch 6. By setting the protective shell 1 as a first shell 11 and a second shell 12 that are snap-fitted and spliced, the spliced connection is not firm, which is beneficial to reducing the impact force required for the flame retardant to eject. By pulling out the conical tube 51 from the handle 5, the length of the device can be increased, making it easier for the device to hit the branches inside the crown, and enabling the fire extinguishing bomb to accurately explode on the crown.

[0029] Please refer to Figures 1 to 5 , a fire extinguishing bomb device for remotely hand-throwing and extinguishing crown fires, comprising: a protective shell 1 and a conical tube 51. The protective shell 1 includes a first shell 11 and a second shell 12, and the right end of the first shell 11 is coaxially connected to the second shell 12. A safety catch 6 is provided between the first shell 11 and the second shell 12. The materials of the first shell 11 and the second shell 12 are straight tubular rotational molding materials. Threaded connections are provided at both left and right ends of the protective shell 1 with handles 5, and at least one set of conical tubes 51 are coaxially inserted inside the handles 5. Two sets of handles 5 and conical tubes 51 are symmetrically arranged with respect to the safety catch 6;

[0030] Threaded connections are provided for the handles 5 and the conical tubes 51 on both sides of the protective shell 1. The conical tube 51 is similar to a telescopic rod and can extend outward from one side of the protective shell 1 and be caught by one side of the small hole groove of the conical tube 51, so that the impact length of the device can be increased after extension.

[0031] The protective shell 1 is formed by splicing two long straight pipes and is used to store the inner flame retardant liquid. Since the material of the protective shell 1 is a rotational molding material, the protective shell 1 is relatively brittle and can be broken when impacted, thereby releasing the internal flame retardant liquid, which can reduce the occurrence of dud bullets and is beneficial for timely fire extinguishing.

[0032] By threadedly connecting the handles 5 on both sides of the protective shell 1, the occupied area of the device can be reduced during storage and transportation, and the handles 5 can be separately disassembled and replaced through detachable connection. After disassembling the conical tube 51, it can be directly thrown into a ground fire, which can reduce material waste. The lateral space of the fire extinguishing bomb can be increased through the free telescoping of the conical tube 51, making it easier for the device to hit the branches inside the tree crown and enabling the fire extinguishing bomb to accurately explode on the tree crown.

[0033] The safety buckle 6 is used to connect the first shell 11 and the second shell 12, which can improve the connection stability between the first shell 11 and the second shell 12 and keep the inside of the protective shell 1 sealed. In some other embodiments of the present application, by removing the safety buckle 6, the first shell 11 and the second shell 12 are integrally die-cast and formed, and the inside of the first shell 11 and the second shell 12 can also be kept as a sealed structure.

[0034] A connection port 2 is fixed on one side of the first shell 11 close to the second shell 12, and an interface 3 is clamped inside the connection port 2. The diameter of the connection port 2 is larger than that of the interface 3. By inserting the interface 3 inside the connection port 2, the first shell 11 and the second shell 12 form a communication structure through the connection port 2 and the interface 3. Since a sealing ring is provided between the connection port 2 and the interface 3, the connection tightness between the two groups of shells can be improved. When the connection port 2 is separated, the flame retardant liquid in the two shells can be ejected simultaneously, avoiding the re-ignition of the flame caused by successive bursts. A fixing ring 21 is fixed inside the connection port 2, and multiple groups of fixing protrusions 31 are arranged around the outside of the interface 3. By the mutual engagement of the fixing protrusions 31 and the fixing ring 21, the two groups of shells can be connected. At the same time, the connection is not firm due to the plastic deformation during this kind of engagement, resulting in the separation of the two groups of the first shell 11 and the second shell 12 even if the main body of the protective shell 1 is not impacted and only the handle 5 is impacted.

[0035] Threaded protrusions 13 are fixed on both ends of the protective shell 1, and the outer side of the threaded protrusion 13 is threadedly connected to the connecting tube 4. The handle 5 can be removed from the protective shell 1 through the threaded connection, thereby reducing the occupied area and facilitating transportation. A slide groove is arranged around the outer side of the handle 5, and the conical tube 51 moves along the slide groove, so that the conical tube 51 can be retracted inward like a telescopic rod, which is beneficial to increase the volume of the device itself when the tree crown or the impact surface is small, so as to facilitate crushing on the tree crown. A limiting baffle 52 is fixed on the side of the conical tube 51 away from the protective shell 1, and the diameter of the limiting baffle 52 is larger than the diameter of the tube mouth of the conical tube 51, which is used to prevent the conical tube 51 from being completely retracted into the handle 5, which is beneficial to quick withdrawal, saving usage time and facilitating use.

[0036] The first shell 11 and the second shell 12 form a sealing structure through the connecting port 2 and the connecting port 3 to avoid leakage of flame retardant liquid, which leads to a decrease in fire extinguishing ability. The safety buckle 6 includes a connecting buckle 61, an anti-dropout protrusion 62 and a locking tongue 63. The outer side of the connecting port 2 is provided with a connecting buckle 61, and the inner side of the connecting buckle 61 is engaged with an anti-dropout protrusion 62, and an anti-dropout protrusion 62 is fixed between the connecting buckle 61 and the locking tongue 63. By inserting the locking tongue 63 into the connecting buckle 61, the anti-dropout protrusion 62 on the inner side of the connecting buckle 61 is engaged with the locking tongue 63, so that the safety buckle 6 can limit the position of the connecting port 2 to avoid separation of the two groups of shells, and can further improve the tightness of the connection between the two groups of shells, so as to prevent the fire extinguishing disc from being used due to improper operation during storage or transportation. The connecting buckle 61 forms a disassembly structure through the anti-dropout protrusion 62 and the locking tongue 63. When in use, the safety buckle 6 is removed to reduce the tightness of the connection to facilitate the rupture of the fire extinguishing disc.

[0037] In conjunction with the accompanying drawings and implementation modes, a fire extinguishing bomb device provided by the utility model for long-distance hand-throwing to extinguish tree crown fire is further described below.

[0038] When a fire occurs on the tree crown, the user stands in a relatively safe position, tightens the connecting pipe 4 to the outside of the threaded protrusion 13, and pulls the conical tube 51 outward along the slide groove to the farthest state, and applies force to the side of the locking tongue 63 to make the locking tongue 63 staggered from the connecting buckle 61 until the locking tongue 63 is separated from the anti-detachment protrusion 62, thereby removing the safety buckle 6 from the device, and the user holds the handle 5 and throws it toward the burning tree crown. When the conical tube 51 or the protective shell 1 collides with the branch, the huge impact will cause the fixing protrusion 31 to separate from the fixing ring 21, so that the flame retardant liquid will spray outward from the connecting port 2 and the connecting port 3 and contact the flame, causing the flame to drop below the combustion point, thereby completing the fire extinguishing.
