Electrically activated fire extinguishing device

Abstract

This utility model discloses an electrically activated fire extinguishing device, including a bottle body. A reusable container valve is sealed on the top of the bottle body. An electromagnetic actuator for controlling start and stop is installed on the top of the container valve. A sensor assembly is electrically connected to the top of the electromagnetic actuator. Abnormal signals are transmitted through a smoke sensor and a temperature sensor. When the electromagnetic actuator receives an abnormal signal, it activates, pushing a push gate to squeeze a living body downwards. The living body, through a compression spring, squeezes a pressure ring downwards, causing the pressure ring to displace downwards. This causes a push rod inside the pressure ring to extend downwards out of the valve core and puncture the safety diaphragm, connecting to the inside of the bottle body, thereby opening the container valve. This enables rapid activation of the fire extinguishing device to extinguish fires inside rapidly burning electrical component cabinets. Furthermore, the components inside the container valve can be reset under the action of the compression spring and a return spring. The safety diaphragm can be quickly disassembled and replaced using a safety screw, allowing the device to be used multiple times and reducing operating costs.

Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing equipment technology, specifically to an electrically activated fire extinguishing device. Background Technology

[0002] Fire extinguishing devices are one of the core components of fire protection systems, extinguishing fires through physical isolation, chemical inhibition, or cooling.

[0003] Currently common mechanical temperature-controlled sprinkler fire extinguishers require the ambient temperature to rise to a specific threshold before they will break and activate. The cabinet containing electrical components cannot meet the fire extinguishing response requirements in scenarios of rapid combustion. Manual fire extinguishers, on the other hand, require operators to hold them at close range, which poses a low safety risk in complex toxic smoke scenarios and may delay the timing of fire extinguishing. Therefore, it is necessary to design an electrically activated fire extinguishing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an electrically activated fire extinguishing device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an electrically activated fire extinguishing device, comprising a bottle body, a reusable container valve sealed on the top of the bottle body, an electromagnetic actuator for controlling start and stop installed on the top of the container valve, a sensor assembly electrically connected to the top of the electromagnetic actuator, the sensor assembly including a smoke sensor and a temperature sensor electrically connected to the electromagnetic actuator, and a connecting hose sealed on one side of the container valve.

[0006] Preferably, the container valve includes a valve body, a valve core is installed in the valve body, a pressure ring is provided at the top of the valve core, the pressure ring is located in the valve core, a return spring is also provided at the bottom of the pressure ring in the valve core, a pressure spring is abutted at the top of the pressure ring, a living body is sleeved in the top of the pressure spring, the living body slides through the valve cover, and the valve cover is sealed to the valve body.

[0007] Preferably, a safety diaphragm is provided at the bottom of the valve core inside the valve body. The safety diaphragm is installed at one end of a safety screw, and the safety screw is sealed on one side of the valve body.

[0008] Preferably, the top side of the valve body is also provided with a pressure gauge switch nut for switching the pressure valve on and off.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] 1. In this utility model, abnormal signals are transmitted by smoke and temperature sensors. The electromagnetic actuator receives the abnormal signals and starts, pushing the lever downward to squeeze the living body. The living body squeezes the pressure ring downward through the compression spring, causing the pressure ring to move downward. This causes the push rod inside the pressure ring to extend downward out of the valve core and puncture the safety diaphragm, connecting to the inside of the bottle to open the container valve. This enables the rapid activation of the fire extinguishing device to extinguish fires inside rapidly burning electrical component cabinets. Furthermore, the components inside the container valve can be reset under the action of the compression spring and return spring. The safety diaphragm can be quickly disassembled and replaced using safety screws, allowing the device to be used multiple times and reducing operating costs. Attached Figure Description

[0015] 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.

[0016] Example 1

[0017] Please refer to Figure 1-3 As shown, this utility model provides an electrically activated fire extinguishing device, including a bottle body 1. A reusable container valve 2 is sealed and installed on the top of the bottle body 1. An electromagnetic actuator 3 for controlling start and stop is installed on the top of the container valve 2. A sensor assembly is electrically connected to the top of the electromagnetic actuator 3. The sensor assembly includes a smoke sensor and a temperature sensor electrically connected to the electromagnetic actuator. A connecting hose 4 is also sealed and installed on one side of the container valve 2.

[0018] Specifically, the container valve 2 includes a valve body 21, a valve core 22 installed inside the valve body 21, a pressure ring 23 located at the top of the valve core 22, the pressure ring 23 located inside the valve core 22, a return spring located at the bottom of the pressure ring 23 located inside the valve core 22, a push rod integrally provided at the bottom of the pressure ring, the return spring surrounding the outside of the push rod, a pressure spring 25 abutting the top of the pressure ring 23, a live body 24 sleeved inside the top of the pressure spring 25, the live body 24 slidingly passing through the valve cover 26, the valve cover 26 being sealed to the valve body 21, a safety diaphragm 27 located at the bottom of the valve core 22 located inside the valve body 21, the safety diaphragm 27 being installed at one end of a safety screw 28, the safety screw 28 being sealed to one side of the valve body 21, and a pressure gauge switch nut 29 for switching the pressure valve located on one side of the top of the valve body 21.

[0019] In the event of a fire, the smoke sensor or temperature sensor triggers an alarm and transmits an electrical signal to the electromagnetic actuator 3. The electromagnetic actuator 3 then activates the internal electromagnet, which pushes the gate to press down on the living body 24. The living body 24, through the compression spring 25, presses down on the pressure ring 23, causing the pressure ring 23 to move downward. This causes the push rod inside the pressure ring 23 to extend downward out of the valve core 22 and puncture the safety diaphragm 27, connecting to the inside of the bottle body 1 to open the container valve 2.

[0020] The safety diaphragm 27 is installed inside the valve body 1 at the bottom of the valve core 22 by the safety screw 28, which facilitates the replacement of the safety diaphragm 27. Furthermore, the pressure ring 23, the push rod, and the piston 24 can be reset after the electromagnetic actuator 3 stops working under the action of the return spring and the pressure spring 25, so that the container valve 2 can be used multiple times.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
