Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of thermal start fire extinguishing devices, and particularly relates to an explosion suppression type thermal start fire extinguishing device. Background Technique
[0002] Currently, the aerosol fire extinguishing devices triggered by the thermal start method mainly place one end of the thermal initiator outside the device to achieve its fire protection function. When the temperature in the protected space reaches the triggering condition of the device, the external thermal initiator will trigger the device to spray out the aerosol fire extinguishing medium through combustion to achieve the fire protection effect. Due to advantages such as low cost, simple structure, easy installation and maintenance, etc., this type of device has been widely used in non-explosive environments such as engine compartments and electrical cabinets. However, in scenarios such as combustible gas storage cabinets or battery boxes where explosive environments are likely to occur, this type of aerosol automatic fire extinguishing device with an external thermal initiator has non-negligible drawbacks due to the open flame generated during the combustion of the thermal initiator. Content of the Utility Model

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used in the description of the present application herein are only for the purpose of describing specific embodiments and are not intended to limit the present application.
[0032] It can be understood that spatial relationship terms such as "under", "below", "lower", "beneath", "above", "upper", etc. can be used herein to describe the relationship between one element or feature shown in the drawings and other elements or features. It should be understood that in addition to the orientation shown in the drawings, spatial relationship terms also include different orientations of the device during use and operation. For example, if the device in the drawings is flipped, elements or features described as "under other elements" or "beneath" or "under" will be oriented "above" other elements or features. Therefore, the exemplary terms "under" and "below" can include both the upper and lower orientations. In addition, the device can also include other orientations (such as rotating 90 degrees or other orientations), and the spatial description terms used herein are accordingly interpreted.
[0033] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element or connected to the other element through an intermediate element.
[0034] An explosion suppression type thermal start fire extinguishing device provided by the utility model is exemplified as Figure 1 shown, and its main function is realized through a structure such as Figure 2 shown.
[0035] An explosion suppression type thermal start fire extinguishing device includes a housing, an aerosol generating agent 1 and a thermal initiator 6. The aerosol generating agent 1 is filled in the housing, and one end of the thermal initiator 6 is connected to the central position of the aerosol generating agent 1, and the other end is arranged along the inner wall of the housing.
[0036] One end of the thermal initiator 6 is connected to the central position of the aerosol generating agent 1, and the other end extends to the inner edge of the housing and surrounds the inner wall of the housing for one week. The thermal initiator is used to automatically initiate the aerosol gas generating agent when the ambient temperature reaches a preset value.
[0037] Specifically, the housing is cubic in shape and includes upper and lower surfaces and four side surfaces, and the other end of the thermal initiator 6 surrounds the inner walls of the four side surfaces for one week.
[0038] In this embodiment, an ignition charge packet 3 is further included. The ignition charge packet 3 is connected to the central position of the aerosol generating agent 1 in the housing and is connected to the thermal initiator 6. The ignition charge packet can expand the heat of the thermal initiator.
[0039] More specifically, the thermal initiator 6 is a thermal sensitive wire.
[0040] Preferably, the aerosol generating agent 1 is a square agent and is composed of 1 to 6 square medicine columns. The aerosol generating agent is composed of multiple square medicine columns and can be spliced as required according to the size of the fire extinguishing device during use.
[0041] Further, the aerosol generating agent 1 is encapsulated by a plastic moisture-proof bag.
[0042] Further, the aerosol generating agent 1 is encapsulated by a paper bag.
[0043] In this embodiment, a tape is further included. The tape fixes the aerosol generating agent 1 sleeved with the plastic moisture-proof bag and the thermal initiator 6 together, so as to realize the tight contact and fixation between the thermal initiator 6 and the aerosol generating agent 1.
[0044] Furthermore, a plurality of spray nozzles 4 are spaced apart around the side surface of the housing for one week, and the spray nozzles 4 are sealed with stickers.
[0045] Specifically, a plurality of spray nozzles are opened on the four side surfaces of the housing.
[0046] Specifically, the housing includes an upper cover 2 and a lower cover 7, and the upper cover 2 and the lower cover 7 are fixed by rivets 5.
[0047] Further, the rivet 5 is a blind rivet 5.
[0048] Further, the ignition charge packet 3 is fan-shaped, and the fan shape is beneficial to increasing the contact area with the aerosol generating agent, thereby more quickly igniting the aerosol generating agent.
[0049] When a fire occurs, after the temperature reaches the ignition temperature of the thermal initiator 6, the thermal initiator 6 immediately catches fire, and the device releases the aerosol fire extinguishing medium to act on the fire scene. The thermal initiator 6 is isolated from the external environment by the device housing, and the explosive gas cannot come into contact with the burning thermal initiator 6, so gas combustion and explosion will not occur.
[0050] On the one hand, this explosion suppression type thermal start-up fire extinguishing device avoids the dangerous situation of mis-starting during the manufacturing, transportation, installation, etc. of the traditional thermal initiator 6 exposed outside the device; more importantly, it avoids the phenomenon of combustion and explosion caused by the device itself generating open flames when applied in scenarios such as flammable gas storage cabinets or battery boxes where explosive environments are likely to occur.
[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
