Description

Technical Field

[0001] The utility model relates to a fire extinguisher device, in particular to a multi - purpose fire extinguisher device. Background Art

[0002] A granary is the main facility for storing grains. Since a large amount of grains are piled up in the granary, the heat inside the granary is not easily dissipated. When the temperature is relatively high, the heat is likely to accumulate inside the granary and cause the grains to spontaneously combust. In the prior art, the granary mainly realizes the heat exchange inside and outside the granary through various ventilation devices to dissipate heat, and the fire extinguishing devices for grains are often common fire extinguishing methods on the market, such as a sprinkler system or equipped with fire extinguishers.

[0003] However, there is no multi - purpose fire extinguisher device on the market that can blow air to cool the grains when used in a granary and can quickly respond as a fire extinguishing device to extinguish fires when a fire occurs. Summary of the Utility Model

[0004] In order to solve the deficiencies of the above - mentioned technologies, the utility model provides a multi - purpose fire extinguisher device.

[0005] In order to solve the above - mentioned technical problems, the technical scheme adopted by the utility model is as follows: It includes a main body structure. The main body structure includes a tee connector and an expansion part connected to the tee connector. The other end of the expansion part is provided with an extension connecting pipe.

[0006] The tee connector includes a nozzle end, a fire - extinguishing medium inlet end, and a compressed air inlet end. The confluence connection between the nozzle end and the compressed air inlet end is a narrow channel, and the confluence connection between the nozzle end and the fire - extinguishing medium inlet end is an inlet path.

[0007] A retaining tongue is formed on the outer circumference of the tube body of the compressed air inlet end, and the compressed air inlet end is connected to a connecting pipe through the retaining tongue.

[0008] Further, the nozzle end and the compressed air inlet end are in the same plane.

[0009] Further, the internal channel of the nozzle end is an inclined surface through - cavity, and the inclined surface through - cavity is implemented in such a way that the diameter gradually increases from the end where it is connected to the narrow channel to the free end.

[0010] Further, the maximum diameter of the narrow channel is smaller than the maximum diameter of the internal channel of the compressed air inlet end.

[0011] Further, the compressed air inlet end is connected to a front - end compressed air pump through a connecting pipe.

[0012] Further, the fire - extinguishing medium inlet end and the nozzle end are arranged perpendicular to each other, and the maximum diameter of the internal channel of the fire - extinguishing medium inlet end is larger than the maximum diameter of the inlet path.

[0013] Furthermore, the converging path is inclined and connected to the side of the inclined surface through - cavity.

[0014] Furthermore, the spoiler includes an integrally - formed straight - plate part and a twisted - plate part;

[0015] The straight - plate part has a straight - plate structure and its maximum width is greater than the maximum diameter of the internal channel at the compressed - air inlet end, so the straight - plate part is located outside the compressed - air inlet end;

[0016] The maximum width of the twisted - plate part is adapted to the maximum diameter of the internal channel at the compressed - air inlet end, so the twisted - plate part is inserted into the internal channel of the compressed - air inlet end.

[0017] Furthermore, the extension connecting pipe is connected to the front - end fire - fighting system.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] The following further describes the utility model in detail with reference to the drawings and specific embodiments.

[0025] As Figures 1-4As shown together, this embodiment relates to a multi-purpose fire extinguisher device, including a main structure 1. The main structure 1 includes a three-way connector 2 and an expansion part 13 connected to the three-way connector 2. The other end of the expansion part 13 is provided with an extension connecting pipe 14. In this embodiment, the three-way connector 2 enables three states: separate blowing, separate fire extinguishing, and atomizing the fire extinguishing medium to assist in fire extinguishing. It should be noted that this embodiment is for extinguishing fires in grains. Therefore, the fire extinguishing medium in this embodiment is preferably water. Thus, it can be understood that the atomizing of the fire extinguishing medium to assist in fire extinguishing in this embodiment is specifically the atomization of water.

[0026] In this embodiment, the three-way connector 2 includes a nozzle end 3, a fire extinguishing medium inlet end 4, and a compressed air inlet end 5. The confluence connection between the nozzle end 3 and the compressed air inlet end 5 is a narrow channel 7, and the confluence connection between the nozzle end 3 and the fire extinguishing medium inlet end 4 is an inlet path 6; a tongue 8 is formed on the outer circumference of the pipe body of the compressed air inlet end 5, and the compressed air inlet end 5 is connected to the connecting pipe 9 through the tongue 8; it also includes a spoiler 10 inserted into the channel of the compressed air inlet end 5.

[0027] Preferably, the nozzle end 3 and the compressed air inlet end 5 are in the same plane. It can be understood that the nozzle end 3 in this embodiment is the ejection end of compressed air and / or the fire extinguishing medium. In order to make the ejection of compressed air smoother, it is therefore arranged on one side of the same horizontal plane as the nozzle end 3, and the flow direction of the compressed air is towards the nozzle end 3 side.

[0028] The internal channel of the nozzle end 3 is an inclined plane through cavity 15, and the inclined plane through cavity 15 is implemented in such a way that the diameter gradually increases from the end where it is connected to the narrow channel 7 to the free end. That is to say, the inclined plane through cavity 15 makes the diameter of the nozzle end 3 larger from the narrow channel 7 side to the free end side, which helps the diffusion of the fluid medium.

[0029] The maximum diameter of the narrow channel 7 is smaller than the maximum diameter of the internal channel of the compressed air inlet end 5. Therefore, the flow rate of the compressed air will become faster after passing through the narrow channel 7, which further helps the air to be ejected. In the case where the granary only needs to dissipate heat, this embodiment can drive the air flow in the granary; on this basis, the compressed air inlet end 5 is connected to the front-end compressed air pump through the connecting pipe 9. The compressed air pump is the source of compressed air, and the structure of the compressed air pump and its settings are prior art, so they are not shown in this application.

[0030] The fire extinguishing medium inlet end 4 and the nozzle end 3 are perpendicularly arranged. The maximum diameter of the internal channel of the fire extinguishing medium inlet end 4 is larger than the maximum diameter of the inlet path 6. When the fire extinguishing medium in the internal channel of the fire extinguishing medium inlet end 4 encounters the inlet path 6 with a smaller diameter, the volume passing through per unit time also decreases accordingly. Therefore, the flow rate decreases and the flow velocity increases, which is beneficial to the ejection of the fire extinguishing medium.

[0031] In this embodiment, the inlet path 6 is inclined and connected to one side of the inclined surface through cavity 15. Through the limitation of this technical feature, the inlet point of the inlet path 6 is located on the side of the outflow end of the narrow channel 7, preventing the fire extinguishing medium from flowing into the compressed air inlet end 5 and enabling it to spray into the inclined surface through cavity 15. Moreover, the vertical height of the lower end of the inner surface of the narrow channel 7 is higher than the inlet point of the inlet path 6, thus further preventing the fire extinguishing medium from flowing into the compressed air inlet end 5. In addition, setting the inlet point of the inlet path 6 on the side of the outflow end of the narrow channel 7 is beneficial for the compressed air to break and atomize the fire extinguishing medium, and the atomized fire extinguishing medium has a better fire extinguishing effect.

[0032] The spoiler 10 includes an integrally formed straight plate portion 11 and a twisted plate portion 12. The straight plate portion 11 has a straight plate structure and its maximum width is greater than the maximum diameter of the internal channel of the compressed air inlet end 5, so the straight plate portion 11 is located outside the compressed air inlet end 5. The maximum width of the twisted plate portion 12 is adapted to the maximum diameter of the internal channel of the compressed air inlet end 5, so the twisted plate portion 12 is inserted into the internal channel of the compressed air inlet end 5. The spoiler 10 is used to generate eddy currents in the compressed air. When the compressed air passes through the twisted plate portion 12, due to the separation and attachment of the twisted plate portion 12, eddy currents are generated in the compressed air. Therefore, when this embodiment is in the state of blowing air alone, the blown air is eddy current air, which is further beneficial to the air flow in the granary. When this embodiment is in the state of assisting fire extinguishing with atomized fire extinguishing medium, the atomized fire extinguishing medium is more conducive to the eddy current diffusion of the fire extinguishing medium under the action of the eddy current air, and the fire extinguishing effect is better.

[0033] The extension connecting pipe 14 is connected to the front-end fire protection system. Actually, the extension connecting pipe 14 is connected to the pipeline of the fire protection system. The fire protection system and its pipe system are prior arts. The inner diameter of the expansion portion 13 is larger, which is used to improve the compressive capacity.

[0034] In this way, the multi-purpose fire extinguisher device disclosed by the present utility model has a working state of blowing air alone when there is no fire, a working state of extinguishing fire alone when there is a fire, and a working state of assisting fire extinguishing with atomized fire extinguishing medium when the fire is serious. It serves multiple purposes and has strong compatibility. Moreover, it can ventilate and blow air in the granary at ordinary times to accelerate air flow, and can quickly carry out fire extinguishing operations when there is a fire, with a fast response and a good fire extinguishing effect.

[0035] The above embodiments are not limitations to the present utility model, and the present utility model is not limited to the above examples. Changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model also fall within the protection scope of the present utility model.
