technical field

The invention relates to the field of fire fighting, in particular to a dry ice fire extinguishing bomb.

Background technique

At present, there are many kinds of fire extinguishers, and most of the fire extinguishers that are used in daily life are open fire extinguishers. The spraying distance of this kind of fire extinguishing agent is limited, so that people must be close to the fire source, and personal safety is threatened; with the development of human science and technology, there have been fire extinguishing bombs that can be thrown directly at the fire affected area by hand to extinguish the fire. Use the pressure and gas produced by the acid-base reaction to extinguish the fire, but this kind of fire extinguisher will pollute the extinguished objects, so it is not suitable for power line fires or live equipment fire extinguishing.

In a further technical solution, the pusher includes a push handle and a push pin, the push pin is located in the water containing chamber, the push handle extends into the water containing chamber and is in sliding and sealing fit with the wall of the water containing chamber, and the push pin is connected to the inside of the push handle end, push the push handle inward, and the push needle can pierce the spacer, allowing water to enter the dry ice chamber to react with the dry ice.

In a further technical solution, a push plate is provided at the outer end of the push handle, and an elastic structure is provided between the push plate and the wall of the water chamber.

In a further technical solution, the elastic structure is a compression spring, which is sleeved on the push handle.

The elastic structure is that a guide post is respectively arranged on the upper and lower sides of the push plate, a guide sleeve slidingly fitted with the guide post is fixed outside the wall of the water chamber, and a compression spring is sleeved on each guide sleeve.

In a further technical solution, a gasket is provided between the compression spring and the wall of the water chamber, and the push handle passes through the gasket.

In a further technical solution, at least one sealing sheet is provided on the spacer, and the push pin is directly opposite to the sealing sheet.

In a further technical solution, an anti-touch protection structure is provided outside the propeller, the anti-touch protection structure includes a protective cover, and the protective cover is threadedly connected with a threaded buckle provided on the wall of the water storage chamber.

In a further technical solution, the structure of the shell is capsule-shaped, the warheads at both ends of the shell are screwed to the middle section of the shell, and the water chamber is at one end of the shell.

The beneficial effects produced by adopting the above-mentioned technical solution are: in the present invention, after the spacer is pierced, the dry ice and water are mixed and gasified to form carbon dioxide, and the volume expands rapidly, thereby causing an explosion, causing the shell to be broken, and the carbon dioxide is released to extinguish the fire; That is, solid carbon dioxide, which has a wide range of sources and is non-corrosive. It will not pollute the environment of the fire scene during fire extinguishing. It can escape quickly after fire extinguishing without leaving traces. It is suitable for fighting various flammable liquid fires, and some solids that are afraid of pollution and damage Fire, in addition, carbon dioxide is non-conductive and can be used to extinguish the fire of live equipment, especially suitable for application in power systems, it can destroy bird nests, fire extinguishing and small blasting under live conditions.

detailed description

The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The present invention provides a dry ice fire extinguishing bomb as shown in Figure 1, comprising a shell 1, the shell 1 is divided into two chambers by a spacer 5, one chamber is a water chamber 6, and the other chamber is a dry ice chamber 7. A propeller 2 capable of penetrating the isolation sheet 5 is provided on one side of the water holding chamber 6 . After the spacer 5 is punctured, the dry ice and water are mixed and gasified to form carbon dioxide, which rapidly expands in volume and breaks the shell 1, and the carbon dioxide is released to extinguish the fire.

A specific embodiment of the propeller 2 is as follows, the propeller 2 includes a push handle 22 and a push pin 21, the push pin 21 is located in the water containing chamber 6, and the push handle 22 extends into the water containing chamber 6 and is connected with the water containing chamber The wall of the chamber 6 is sliding and sealed, and the push pin 21 is connected to the inner end of the push handle 22, and the push handle 22 is pushed inward, and the push pin 21 can pierce the spacer 5, so that water enters the dry ice chamber 7 and reacts with the dry ice.

As a further optimized structure, the outer end of the push handle 22 is provided with a push plate 26, and an elastic structure is arranged between the push plate 26 and the wall of the water chamber 6. The existence of the elastic structure makes the propeller 2 need a certain External force propulsion can advance and puncture the spacer 5, avoiding the danger of accidental collision. At the same time, when the external force is stopped, the propeller 2 resets, and the punctured small hole can also be kept out of the way, so that water can pass through.

As a preferred structure, the elastic structure is a compression spring 25, which is sleeved on the push handle 22. The compression spring 25 plays a role in positioning the propeller 2. When there is no external force, the push plate 26 acts on the compression spring 25. Can not advance inwardly, under the action of external force, give push plate 26 thrusts, push pin 21 pierces spacer 5 forward.

Referring to Fig. 2, another structure of the elastic structure is that a guide post 24 is respectively arranged on the upper and lower sides of the push plate 26, and a guide sleeve that slides with the guide post 24 is fixed outside the wall of the water holding chamber 6. 23, each guide sleeve 23 is covered with stage clip 25.

In order to further seal the water chamber 6, a gasket is provided between the compression spring 25 and the wall of the water chamber 6, the push handle 22 passes through the gasket, and the gasket can further prevent water leakage.

The spacer 5 is provided with at least one sealing sheet 8, the push pin 21 is facing the sealing sheet 8, and the sealing sheet 8 is made of easy-to-puncture material. In the embodiment listed by the present invention, as shown in Figure 3, there are four sealing sheets 8 on the spacer sheet 5, and there are four corresponding push pins 21, so as to increase the passage of water and make the dry ice quickly sublime into gas.

In order to avoid accidental collision during transportation and storage, an anti-touch protection structure is provided outside the propeller 2. The anti-touch protection structure includes a protective cover 3, and the protective cover 3 is connected to the wall of the water holding chamber 6. 4 threaded connections on the turnbuckle. When in use, the protective cover 3 is opened and the propeller 2 is pushed to puncture the spacer 5 to realize the mixing of water and dry ice.

The structure of the shell 1 provided by the present invention is capsule-shaped, the warheads at both ends of the shell 1 are screwed to the middle section of the shell 1 , and the water chamber 6 is at one end of the shell 1 . This shape is easier to store and put away.

The above-mentioned embodiments are only preferred specific embodiments of the present invention.
