Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, and in particular to a circumferential spray fire extinguishing device. Background Technology

[0002] Thermal aerosol fire extinguishing devices have been widely used due to their high extinguishing efficiency, small size, and environmental friendliness. These devices use electricity and / or heat to provide the aerosol generator inside the device with sufficient starting energy, causing the aerosol generator to burn layer by layer, thus allowing the device to release the aerosol extinguishing agent stably and evenly.

[0003] Traditional fire extinguishing systems typically have a fixed spray direction, but in actual fires, the ignition point may often be outside the pre-set coverage area of ​​the nozzle. Therefore, our company's technical staff has proposed a circumferential spray fire extinguishing system. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the problems existing in the background art and provide a circumferentially spraying fire extinguishing device, which achieves circumferential spraying of the fire extinguishing medium by installing circumferential components on the fire extinguishing device.

[0005] To achieve the above-mentioned technical features, the purpose of this utility model is as follows: a circumferentially spraying fire extinguishing device includes a housing, one end of which is equipped with a fire extinguishing agent, and the other end of the housing is provided with a nozzle. An activation device is installed on the fire extinguishing agent. A circumferential assembly is provided on one side of the housing located at the nozzle. The circumferential assembly includes a connecting rod and a baffle. One end of the connecting rod is connected to the housing, and the other end is connected to the baffle.

[0006] The baffle is a flat plate.

[0007] The baffle is an outwardly convex plate.

[0008] The baffle is an inwardly convex plate.

[0009] The baffle is provided with multiple through holes.

[0010] The edge of the baffle is provided with a folded edge.

[0011] The baffle is telescopically and movably mounted on the housing.

[0012] The connecting rod is slidably inserted into the housing at one end located at the nozzle, and a limiting element is installed at the other end of the connecting rod located inside the housing.

[0013] The housing is also equipped with a partition net. The connecting rod includes a tube and a rod. One end of the tube is fixedly connected to the partition net, and the other end extends out from the end of the housing located at the nozzle. One end of the rod is fixedly connected to a baffle, and the other end extends into the tube. An elongated hole is provided axially on the tube. A limiting member is inserted into the elongated hole and fixedly connected to the rod. The limiting member is a limiting pin.

[0014] The housing is filled with cooling material between the mesh and the nozzle.

[0015] Compared with the prior art, the outstanding features of this utility model, which adopts the above technical solution, are:

[0016] 1. After the fire extinguishing agent is activated by the starting device, the fire extinguishing medium is sprayed out from the nozzle to extinguish the fire. Since the baffle is located in front of the nozzle, the fire extinguishing medium is blocked by the baffle and thus sprayed in a circumferential direction.

[0017] 2. The baffle of this utility model is provided with multiple through holes. These through holes allow some of the extinguishing medium to pass through and enter the front of the baffle.

[0018] 3. The baffle of this utility model is telescopically and movably installed on the housing, reducing the distance between the baffle and the housing, and preventing the connecting rod from bending during transportation or installation of the fire extinguishing device.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] It should be noted that the use of terms such as "an embodiment," "an embodiment," "an exemplary embodiment," and "some embodiments" in the specification indicates that the described embodiment may include a specific feature, structure, or characteristic, but not every embodiment necessarily includes that specific feature, structure, or characteristic. Furthermore, when a specific feature, structure, or characteristic is described in connection with an embodiment, implementing such a feature, structure, or characteristic in conjunction with other embodiments (whether explicitly described or not) should be within the knowledge of those skilled in the art.

[0035] Example 1:

[0036] See Figure 1 A circumferentially spraying fire extinguishing device includes a housing 10, an extinguishing agent 11 installed at one end of the housing 10, a nozzle 12 provided at the other end of the housing 10, an activation device 14 installed on the extinguishing agent 11, and a circumferential assembly 30 provided on one side of the housing 10 located at the nozzle 12. The circumferential assembly 30 includes a connecting rod 31 and a baffle 32. One end of the connecting rod 31 is connected to the housing 10, and the other end is connected to the baffle 32.

[0037] Specifically, the housing 10 is a hollow cylinder. Fire extinguishing agent 11 is installed inside one end of the housing 10, and a nozzle 12 is provided on the end face of the other end. The starting device 14 is installed on the starting end face of the fire extinguishing agent 11. The starting device 14 can be an electronic ignition head or a thermal wire. When the starting device 14 is an electronic ignition head, the electronic ignition head is bonded to the starting end face of the fire extinguishing agent 11, and the wire of the electronic ignition head passes through the bottom of the housing 10. When the starting device 14 is a thermal wire, one end of the thermal wire is wrapped around and bonded to the starting end face of the fire extinguishing agent 11, and the other end passes through the bottom of the housing 10.

[0038] After the extinguishing agent 11 is activated by the starting device 14, the extinguishing medium is sprayed out from the nozzle 12 to extinguish the fire. Because the baffle 32 is located in front of the nozzle 12, the extinguishing medium is blocked by the baffle 32, thus spraying out in a circumferential direction. Figure 4 As shown.

[0039] In the preferred embodiment, see Figure 5 The baffle 32 is a flat plate 321.

[0040] In the preferred embodiment, see Figure 6 The baffle 32 is an outwardly convex plate 324.

[0041] In the preferred embodiment, see Figure 7 The baffle 32 is an inner convex plate 325.

[0042] To improve the structural strength of the baffle 32, the edge of the baffle 32 is also provided with a folded edge 323.

[0043] Example 2:

[0044] Based on Embodiment 1, the baffle 32 is provided with multiple through holes 322. By providing the through holes 322, some of the extinguishing medium can pass through the through holes 322 and enter the front of the baffle 32, such as... Figure 4 As shown.

[0045] The through hole 322 can correspond to or be offset from the nozzle 12. When the through hole 322 is offset from the nozzle 12, the baffle 32 is more effective in blocking the extinguishing medium.

[0046] Example 3:

[0047] In order to reduce the distance between the baffle 32 and the housing 11 and prevent the connecting rod 31 from bending during the transportation or installation of the fire extinguishing device, the baffle 32 is telescopically mounted on the housing 10.

[0048] During transportation, please refer to Figure 2 The baffle 32 is positioned towards the nozzle 12. When the fire extinguishing device is activated, the baffle 32 moves away from the nozzle 12 under the impact of the extinguishing medium. (See [reference]). Figure 1 ,4 .

[0049] In this embodiment, the connecting rod 31 is slidably inserted into one end of the housing 10 located at the nozzle 12, and a limiting member 314 is installed at the other end of the connecting rod 31 located inside the housing 10.

[0050] In other words, the housing 10 has a sliding hole at the center of the end face of the nozzle 12, and the connecting rod 31 is slidably guided into the sliding hole. A limiting member 314 is installed at one end of the connecting rod 31 inside the housing 10, and the limiting member 314 prevents the connecting rod 31 from disengaging from the sliding hole.

[0051] In this embodiment, the limiting member 314 may be a pin inserted into or welded to the connecting rod 31, or it may be a snap ring clipped onto the connecting rod 31.

[0052] Example 4:

[0053] The difference between this embodiment and embodiment 3 is that, see [link to embodiment 3]. Figure 2 , 3 The housing 10 is also equipped with a partition net 20. The connecting rod 31 includes a tube body 311 and a rod body 312. One end of the tube body 311 is fixedly connected to the partition net 20, and the other end extends out from the end of the housing 10 located at the nozzle 12. One end of the rod body 312 is fixedly connected to a baffle 32, and the other end extends into the tube body 311. An elongated hole 313 is axially provided on the tube body 311. The limiting member 314 is fixedly connected to the rod body 312 after passing through the elongated hole 313. The limiting member 314 is a limiting pin.

[0054] Furthermore, within the housing 10, a cooling material 15 is filled between the partition 20 and the nozzle 12. The cooling material 15 may be ceramic balls.

[0055] The method of use or principle of this utility model:

[0056] See Figure 4 After the extinguishing agent 11 is activated by the activation device 14, the extinguishing medium is sprayed out from the nozzle 12 to extinguish the fire.

[0057] Since the baffle 32 is located in front of the nozzle 12, part of the extinguishing medium passes through the baffle 32, while the other part of the extinguishing medium is sprayed to the side and rear in a circumferential direction due to the obstruction of the baffle 32.

[0058] While specific embodiments of the present invention have been described above, those skilled in the art should understand that the specific embodiments described are merely illustrative and not intended to limit the scope of the present invention. Any modifications and variations made by those skilled in the art in accordance with the spirit of the present invention should be covered within the scope of protection of the claims of the present invention.
