[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the present application more clear, the technical scheme in the embodiments of the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all the embodiments.

[0017] Therefore, the following detailed description of the embodiments of the present application is not intended to limit the scope of the claimed application, but merely represents some embodiments of the application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of the present application. It should be noted that the embodiments in the present application and the features and technical solutions in the embodiments can be combined with each other without conflict, and attention should be paid to: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0018] For the electrical equipment in the narrow space area such as the cable chamber of the switch cabinet, the secondary room of the switch cabinet, and the low-voltage meter box, the traditional fire extinguishing device is large in size, which limits the installation and use; the present embodiment provides a compact intelligent fire extinguishing device of electric guardian.

[0019] As shown in Figure 1 and Figure 2 , the compact intelligent fire extinguishing device of electric guardian is in the shape of L as a whole, including a fire extinguisher body 1 in the shape of cylinder and a turning nozzle 2 installed at the end of the fire extinguisher body 1 and in a 90° angle with the fire extinguisher body 1. Among them, the fire extinguisher body 1 is the main part of the device, which adopts a hollow tank structure, and stores perfluorocyclohexanone extinguishing agent and nitrogen inside; the perfluorocyclohexanone extinguishing agent has the advantages of high extinguishing efficiency, small damage to equipment, etc., and has little negative impact on the environment, and is suitable for places where important equipment may be stored such as equipment cabinet. The turning nozzle 2 is the outlet of the extinguishing agent, which is the channel switch for the release of the extinguishing agent from the inside of the fire extinguisher to the outside. Reasonable nozzle design can control the spraying direction and speed of the extinguishing agent, and combined with the diffuser 3, the extinguishing agent can be better spread to the target area.

[0020] Further, as shown in Figure 1 and Figure 2As shown, the diffuser 3 is installed on the deflection nozzle 2 in this embodiment, which can expand the spraying range of the extinguishing agent after being sprayed from the deflection nozzle 2. This helps to cover the possible fire area more comprehensively when a fire occurs, improving the efficiency of fire extinguishing. For example, in a device cabinet, the diffuser 3 can ensure that the perfluorocyclohexanone extinguishing agent can reach more corners to prevent the spread of fire. The ether liquid glass tube 4 is provided between the diffuser 3 and the deflection nozzle 2, which is a passage switch between the diffuser 3 and the deflection nozzle 2; the ether liquid glass tube 4 is a temperature sensitive component; at normal temperature, the ether liquid glass tube 4 blocks at the deflection nozzle 2 to prevent the extinguishing agent from leaking; when the temperature exceeds a certain value, the ether liquid glass tube 4 bursts, so that the perfluorocyclohexanone extinguishing agent in the extinguisher body 1 is sprayed out. This temperature triggering mechanism can automatically start the fire extinguishing process when the temperature rises due to a fire, without the need for manual intervention, and responds quickly.

[0021] Further, considering the reuse problem of the electric guardian compact intelligent fire extinguishing device, as shown in Figure 1 and Figure 2 As shown, one end of the extinguisher body 1 in this embodiment is provided with a threaded interface, and the connecting end of the deflection nozzle 2 to the extinguisher body 1 is a nut seat 5, and the deflection nozzle 2 is threadedly connected to the threaded interface of the extinguisher body 1 through the nut seat 5. This detachable connection mode allows the extinguisher body 1 to be returned to the factory for secondary replenishment when the internal pressure decreases or the remaining amount of extinguishing agent is insufficient.

[0022] As a preferred technical solution of this embodiment, as shown in Figure 1 In this embodiment, a transparent and closed volume observation window 6 is also provided on the extinguisher body 1, and a scale table 7 is provided on the volume observation window 6. The volume of perfluorocyclohexanone extinguishing agent in the extinguisher body 1 can be directly observed through the scale table 7 on the volume observation window 6, which is very convenient for the user to know the remaining amount of extinguishing agent in the extinguisher at any time, so as to replenish or replace it in time, and ensure that there is enough extinguishing agent available when a fire occurs.

[0023] As a preferred technical solution of this embodiment, as shown in Figure 1 and Figure 2 In this embodiment, a pressure gauge 8 is also installed at the bottom of the extinguisher body 1, which communicates with the inside of the extinguisher body 1. The pressure gauge 8 is installed at the bottom of the extinguisher, and detects the nitrogen gas pressure in the extinguisher body 1. Nitrogen gas may play a role in pushing the extinguishing agent out of the extinguisher, and by monitoring the gas pressure, it can be ensured that the extinguisher works under normal pressure, and ensures that it can normally spray extinguishing agent when needed.

[0024] In addition, as a preferred technical solution of this embodiment, considering the installation problem of the electric guardian compact intelligent fire extinguishing device, as shown in Figure 1 and Figure 2As shown, a set of mounting seats is arranged on one side of the fire extinguisher body 1 in the embodiment, including a magnetic mounting seat 9 and a patch mounting seat 10. The magnetic mounting seat 9 can be adsorbed in the equipment cabinet by magnetic force to fix the position of the fire extinguisher body 1; the patch mounting seat 10 can be pasted in the equipment cabinet to fix the position of the fire extinguisher body 1, preventing displacement of the fire extinguisher body 1 when the equipment cabinet is subjected to vibration or movement, and ensuring that it can work normally when a fire occurs. Different fixing modes are provided by the magnetic mounting seat 9 and the patch mounting seat 10, which are suitable for the internal structures of different equipment cabinets.

[0025] In summary, the compact intelligent fire extinguishing device is installed in the cable chamber of the switch cabinet, the secondary chamber of the switch cabinet, the low-voltage meter box and other small space areas; when a fire occurs, the ether liquid glass tube 4 bursts, the nitrogen in the fire extinguisher body 1 pushes the perfluorohexone extinguishing agent out of the diffuser 3 on the rotating nozzle 2, thereby quickly extinguishing the flame and reducing fire loss; by effectively controlling the fire in the electrical equipment, the risk of safety accidents is significantly reduced, and the safety of personnel and property is improved.

[0026] When the electrical equipment in the cable chamber of the switch cabinet, the secondary chamber of the switch cabinet and the low-voltage meter box is checked, the state of the fire extinguisher is monitored by the scale 7 and the pressure gauge 8, so that the remaining amount of the extinguishing agent and the nitrogen pressure can be grasped in time, and maintenance and preparation work can be done in advance, thereby improving the reliability of the entire fire extinguishing device.

[0027] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered within the protection scope of the present application.
