Description

Technical Field

[0001] The utility model relates to the technical field of fire fighting equipment, in particular to a fire extinguishing device. Background Art

[0002] Existing pressure-storage liquid fire extinguishing devices often adopt electromagnetic drive mode, and use electromagnetic valves to control the opening and closing of the fire extinguishing device. The electromagnetic valve itself needs to also have the function of sealing the fire extinguishing storage device, so the electromagnetic valve selected for the pressure-storage fire extinguishing device must also have a certain pressure resistance. For fire extinguishing agents such as perfluorohexanone, which need to consider compatibility with materials, the selected electromagnetic valve materials are subject to certain restrictions. Otherwise, the fire extinguishing medium reacts with the electromagnetic valve after long-term contact, and the fire extinguishing device will leak and the safety will be greatly reduced. In addition, the existing pressure-storage liquid fire extinguishing devices basically adopt the working principle of siphon tubes, which makes the fire extinguishing agent storage device have natural limitations in the installation method, which not only greatly limits the application scenarios but also may greatly occupy the use space of the protected object. When the fire extinguishing device needs to be replaced, the entire set of devices is often replaced as a whole, which undoubtedly increases the cost of use. The replacement of the entire set of devices often requires professional personnel to operate, so a fire extinguishing device is proposed for this purpose. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-4 In an embodiment of the utility model, a fire extinguishing device includes a storage tank body 1 and a modular device shell 5 for fixing the storage tank body 1. A release component 2 for controlling the release or closing of the fire extinguishing medium is installed at the release port of the storage tank body 1. A drive motor component 3 and a signal processor 4 are installed inside the cavity of the modular device shell 5. The drive motor component 3 includes a motor 34 and a gear 33 driven by the motor 34, and is configured so that the motor 34 drives the gear 33 to complete the release or closing of the fire extinguishing medium in the storage tank body 1 through the release component 2.

[0020] Specifically, the gear 33 is a sector gear, and a circular gear meshing with the sector gear is provided on the output shaft of the motor 34. The motor 34 has forward and reverse rotation functions, and can control the release and closing of the fire extinguishing medium to achieve timed injection of the entire device. When the release component 2 is a common nozzle, the fire extinguishing medium can be directly sprayed into the protected area.

[0021] See also Figure 2-3 In one embodiment, in this embodiment, preferably, the driving motor assembly 3 also includes a shell 31 installed in the modular device housing 5, and the end surface of the shell 31 fixing the motor 34 is installed with a connecting shaft 32, and the connecting shaft 32 is installed with a gear 33 that can rotate along its axial direction, and the side wall of the gear 33 is installed with a boss 35. Further, when the gear 33 rotates, when the boss 35 is in contact with the release assembly 2, the release assembly 2 and the storage tank body 1 are connected to release the fire extinguishing medium, but when the boss 35 is in contact with the release assembly 2, the release assembly 2 and the storage tank body 1 are connected to release the fire extinguishing medium.

[0022] See also Figure 2-3 In one embodiment, in this embodiment, preferably, the drive motor assembly 3 and the signal processor 4 are both installed inside the cavity of the modular device housing 5, and the drive motor assembly 3 and the signal processor 4 are both located above the storage tank 1.

[0023] See also Figure 1In one embodiment, in this embodiment, preferably, the storage tank body 1 is specifically a binary fire extinguishing medium storage tank body, which contains a bag valve filled with a fire extinguishing agent and a pressurized gas that provides power. Furthermore, the pressurized gas does not contact the fire extinguishing agent, so that the purity of the fire extinguishing agent is guaranteed. Secondly, the binary fire extinguishing medium storage tank body as an independent fire extinguishing agent storage tank body itself has good sealing properties.

[0024] See also Figure 1 In one embodiment, in this embodiment, preferably, the signal processor 4 can be externally connected to a power supply and a detection device, and the signal processor 4 receives the detection signal and sends a forward and reverse rotation signal to control the drive motor assembly 3.

Furthermore, the through groove 53 is specifically an outlet for the fire extinguishing agent, and the through groove 53 is reserved for an external pipeline or nozzle interface.

[0026] The working principle and use process of the utility model are as follows: when a fire occurs in the protection zone, the detector sends a signal to the signal processor 4, and the signal processor 4 issues an instruction to control the motor 34 to rotate forward, the circular gear fixed on the motor shaft drives the gear 33 matched therewith to rotate, and as the gear 33 rotates, the boss 35 on the gear 33 gradually approaches and presses the release component 2 so that the release component 2 and the storage tank body 1 are connected to release the fire extinguishing medium, and when the signal processor 4 issues an instruction to control the motor 34 to reverse, the circular gear fixed on the motor shaft drives the gear 33 matched therewith to rotate, and as the gear 33 rotates, the boss 35 on the gear 33 no longer acts on the release component 2 so that the release component 2 is separated from the storage tank body 1 and stops releasing the fire extinguishing medium.

[0027] Although this specification is described according to implementation modes, not every implementation mode includes only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
