Description

Technical Field

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

[0002] A thermal aerosol fire extinguishing system is a fire-fighting device that uses a combustion reaction to generate an extinguishing agent from an aerosol generator. It consists of an initiator, an aerosol generator and generator, a coolant (device), a feedback element, a casing, and matching fire detection and control devices. It employs a dual extinguishing mechanism of physical cooling and chemical inhibition, offering advantages such as rapid extinguishing speed, all-around coverage, and no need for piping. This device is suitable for enclosed small spaces such as battery compartments and electrical distribution cabinets. We know that in the past, thermal aerosol fire extinguishing systems typically had their canisters placed directly in designated locations. The cylindrical canisters are prone to tipping over, and this problem has not yet been properly solved. Therefore, we propose a thermal aerosol fire extinguishing system. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a thermal aerosol fire extinguishing device.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A thermal aerosol fire extinguishing device includes a storage tank, an initiator on the storage tank, several sets of auxiliary support mechanisms installed on the side of the storage tank, and a nozzle assembly connected to the storage tank via a hose.

[0005] Preferably, the auxiliary support mechanism includes a first fixed block, a lead screw, a slider, a first connecting rod, and a second connecting rod. The first fixed block is fixed to the storage tank. The lead screw is rotatably sleeved inside the first fixed block. The slider is threaded onto the lead screw. The first connecting rod is hinged to the slider. The second connecting rod is hinged between the first connecting rod and the storage tank.

[0006] Preferably, the slider is slidably mounted on the storage tank, and a handwheel is fixed to one end of the lead screw.

[0007] Preferably, one end of the first connecting rod is hinged to a support block.

[0008] Preferably, the nozzle assembly includes a mounting plate, a first sleeve, a feed inlet, a second sleeve, a nozzle, a second fixing block, a rotating shaft, axial flow blades, and spray holes. The first sleeve is fixed on the mounting plate. The first sleeve has a feed inlet communicating with a hose on its side. The first sleeve is connected to the second sleeve. A cross-shaped second fixing block is fixed inside the first sleeve. A rotating shaft is rotatably sleeved on the second fixing block. An axial flow blade is fixed on the rotating shaft. A hemispherical nozzle is fixed on the rotating shaft. The nozzle is rotatably sleeved on the second sleeve. A mesh-like spray hole is opened on the side of the nozzle.

[0009] Compared with the prior art, the beneficial effects of this utility model are: 1. In this utility model, the screw is rotated by the handwheel, and the screw can drive the slider to slide through the threaded transmission between the screw and the slider. The slider pulls the first connecting rod to move, and the first connecting rod and the second connecting rod rotate. At this time, the support block is supported on the ground, which can expand the support area at the bottom and thus improve the stability of the storage tank support.

[0010] 2. In this utility model, after the extinguishing agent is triggered, it enters the feed port through the hose and enters the first sleeve. The flowing extinguishing agent triggers the rotation of the axial flow blades through the axial flow blades. The axial flow blades drive the nozzle to rotate synchronously through the rotating shaft. Thus, the extinguishing agent is sprayed through the nozzle while the nozzle is rotating, resulting in a large spray range and a wider coverage, which improves the efficiency of fire extinguishing.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Reference Figure 1 A thermal aerosol fire extinguishing device includes a storage tank 1, an initiator 2 on the storage tank 1, which, when triggered, can initiate the reaction process of the extinguishing agent. Several sets of auxiliary support mechanisms 3 are installed on the side of the storage tank 1 to assist in supporting the storage tank 1, improve the stability of the storage tank 1, prevent tipping and collision, and provide good protection. The storage tank 1 is connected to a nozzle assembly 5 through a hose 4. The extinguishing agent reaches the nozzle assembly 5 through the hose 4 and is sprayed out through the nozzle assembly 5 to extinguish the fire.

[0015] Reference Figure 3 The auxiliary support mechanism 3 includes a first fixed block 31, a lead screw 33, a slider 34, a first connecting rod 35, and a second connecting rod 36. The first fixed block 31 is fixed to the storage tank 1. The lead screw 33 is rotatably sleeved inside the first fixed block 31. The slider 34 is threadedly sleeved on the lead screw 33. The first connecting rod 35 is hinged to the slider 34. The second connecting rod 36 is hinged between the first connecting rod 35 and the storage tank 1. The slider 34 is slidably mounted on the storage tank 1. A handwheel 32 is fixed to one end of the lead screw 33. A support block 37 is hinged to one end of the first connecting rod 35. By rotating the lead screw 33 through the handwheel 32, the lead screw 33 can drive the slider 34 to slide through the threaded transmission between the lead screw 33 and the slider 34. The slider 34 pulls the first connecting rod 35 to move. The first connecting rod 35 and the second connecting rod 36 rotate. At this time, the support block 37 supports the ground, which can expand the support area at the bottom and thus improve the stability of the support for the storage tank 1.

[0016] Reference Figure 2 The nozzle assembly 5 includes a mounting plate 51, a first sleeve 52, a feed inlet 53, a second sleeve 54, a nozzle 55, a second fixing block 56, a rotating shaft 57, axial flow blades 58, and spray holes 59. The first sleeve 52 is fixed on the mounting plate 51. The feed inlet 53, which communicates with the hose 4, is provided on the side of the first sleeve 52. The second sleeve 54 is connected to the first sleeve 52. A cross-shaped second fixing block 56 is fixed inside the first sleeve 52. The rotating shaft 57 is rotatably sleeved on the second fixing block 56. The axial flow blades 58 are fixed on the rotating shaft 57. 8. A hemispherical nozzle 55 is fixed on the rotating shaft 57. The nozzle 55 is rotatably sleeved on the second sleeve 54. The side of the nozzle 55 is provided with a mesh-like spray hole 59. After the extinguishing agent is triggered, it enters the feed port 53 through the hose 4 and enters the first sleeve 52. The flowing extinguishing agent triggers the axial flow blade 58 to rotate through the axial flow blade 58. The axial flow blade 58 drives the nozzle 55 to rotate synchronously through the rotating shaft 57. Thus, the extinguishing agent sprays through the spray hole 59 at the same time as the nozzle 55 rotates, resulting in a large spray range and wider coverage, which improves the efficiency of fire extinguishing.

[0017] Working principle: When in use, the initiator 2 is triggered to initiate the reaction process of the extinguishing agent. The extinguishing agent reaches the nozzle assembly 5 through the hose 4 and is sprayed out through the nozzle assembly 5 to extinguish the fire. The auxiliary support mechanism 3 is used to support the storage tank 1, improve the stability of the storage tank 1, avoid tipping and collision, and provide good protection.

[0018] The operating principle of the auxiliary support mechanism 3 is as follows: the screw 33 is rotated by the handwheel 32, and the screw 33 can drive the slider 34 to slide through the threaded transmission between the screw 33 and the slider 34. The slider 34 pulls the first connecting rod 35 to move, and the first connecting rod 35 and the second connecting rod 36 rotate. At this time, the support block 37 is supported on the ground, which can expand the support area at the bottom and thus improve the stability of the support for the storage tank 1.

[0019] The operating principle of the nozzle assembly 5 is as follows: after the extinguishing agent is triggered, it enters the inlet 53 through the hose 4 and enters the first sleeve 52. The flowing extinguishing agent triggers the axial flow blade 58 to rotate through the axial flow blade 58. The axial flow blade 58 drives the nozzle 55 to rotate synchronously through the rotating shaft 57. Thus, the extinguishing agent sprays through the nozzle 59 at the same time as the nozzle 55 rotates, resulting in a larger spray range and wider coverage, which improves the efficiency of fire extinguishing.

[0020] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
