Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of fire protection, and relates to a special fire extinguishing device for unattended transformers. Background Art
[0002] Because transformers have high voltage leakage and explosion hazards, electric shocks and casualties are very likely to occur when non-professionals put out fires. Transformer fires start from one point and spread. Firefighters cannot reach the fire scene in time, often missing the first opportunity to put out the fire, resulting in personal safety accidents and property losses.
[0003] The Chinese invention application with the existing publication number CN115754512A, an unmanned substation online monitoring system and method includes an environmental monitoring device, a transformer monitoring device, a lightning arrester monitoring device and an action device; the environmental monitoring device is used to obtain environmental monitoring data of the substation; the environmental monitoring data includes target gas data, smoke sensor data, temperature and humidity data and scene data; the transformer monitoring device is used to obtain transformer monitoring data; the transformer monitoring data includes oil chromatography data, optical fiber temperature measurement data, core grounding data, partial discharge data and bushing dielectric loss data; the lightning arrester monitoring device is used for substation lightning protection processing and obtaining lightning arrester monitoring data; the lightning arrester monitoring data includes the number and frequency of lightning arrester discharges and the amount of lightning arrester leakage current; the action device is used to perform cooling processing, fire extinguishing processing and / or early warning processing according to the environmental monitoring data, the transformer monitoring data and / or the lightning arrester monitoring data.
[0004] The prior art has the following technical defects:
[0005] The above technical solution solves the problem that old transformers in rural towns and remote areas are currently unsupervised. When a fire occurs, the dangerous situation can be discovered in time through online monitoring and remedial measures can be taken in time, but the structure of the specific fire extinguishing device is not publicly described in detail. Utility Model Content
[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a special fire extinguishing device for unattended transformers.
[0007] The utility model discloses a special fire extinguishing device for an unattended transformer, comprising a transformer and a transformer bracket, wherein at least one box is arranged on the transformer bracket, a fire extinguishing pipeline corresponding to the transformer is arranged on the box, a fire extinguishing nozzle is arranged on the fire extinguishing pipeline, an actuator connected to the inside of the fire extinguishing pipeline is arranged in the box, the actuator is connected to a fire extinguishing bottle and a starter, the starter is connected to a temperature sensing detection line and a control module, and the temperature sensing detection line is arranged around the transformer.
[0008] Working process or working principle:
[0009] When in use, when a fire occurs in the transformer, the temperature detection line transmits a signal to the control module, and the control module controls the starter to start. The starter generates gas through the internal solid gas generating agent to hit the actuator. After the actuator connects the fire extinguisher bottle with the fire extinguishing pipeline, the fire extinguishing agent is sprayed onto the transformer through the fire extinguishing nozzle, thereby realizing the function of unmanned automatic fire extinguishing.
[0010] The actuator is fixed in the box body through a fixing plate.
[0011] The actuator includes an actuator body, in which a ejector pin and a blocking block are slidably connected, and the tops of the ejector pin and the blocking block are respectively connected to an ejector pin spring and a return spring. The diaphragm on the fire extinguisher bottle is punctured by the impact of the starter on the ejector pin, so that the fire extinguishing agent is sprayed out of the fire extinguishing nozzle. Since the gas pressure in the fire extinguisher bottle is relatively high, the blocking block can be pushed open to connect the fire extinguisher bottle with the fire extinguishing pipe. When the fire extinguishing agent in the fire extinguisher bottle is released, the pressure is reduced, and the blocking block is reset under the action of the return spring to block the fire extinguishing pipe from being connected with the actuator body, thereby preventing the fire extinguishing agent from entering the interior of the actuator body and causing internal blockage, thereby affecting the movement of the ejector pin.
[0012] The box is also provided with a GPS module, which is connected to the control module. A transformer fire signal is sent through the GPS positioning module and uploaded to the Internet of Things system platform to facilitate rapid positioning of the location of the dangerous situation.
[0013] A solar panel is provided on the top of the fire extinguishing box body, and the solar panel is connected to the control module, so that the power supply demand of the electrical equipment therein can be guaranteed through the solar panel.
[0014] The fire extinguisher bottle is threadedly connected to the actuator, and after use, there is no need to maintain the box body, and only a new fire extinguisher bottle needs to be replaced, which is convenient and quick.
[0015] Compared with the prior art, the beneficial effects of the utility model are:
[0016] The utility model can provide fire control supervision and fire protection measures for transformers that are unattended or in remote use, and has a positioning function to upload the operating status information of the fire extinguishing device; the interface can be expanded to provide joint supervision by the power and fire departments; the fire extinguishing device is maintenance-free, and the fire extinguisher bottle mouth is installed in a rotating manner, which is easy to carry and replace after the fire is extinguished.
