Abstract
The utility model relates to an electric fire disaster pre-alarming safety device, which is connected with a line which uses electricity in series for use; the utility model is composed of a casing, a connecting point of a conducting wire, a printed circuit board, a sensor, an integrated clock, an alarm device, a control circuit, etc., wherein, an electronic switch is composed of a temperature sensor and the integrated clock and the sensor senses the latent heat temperature of the line which uses electricity. When the temperature of the conducting wire exceeds safety and operating temperature, the electric potential of the integrated clock changes to generate audible and visual alarms; a fusing sensor is connected with the line which uses electricity in series; when the temperature of the conducting wire reaches the limited temperature before a fire happens or short circuit of a circuit happens, the circuit is switched off; therefore, fire can be prevented from happening. The product has pre-alarming action and the action of automatic protection; the utility model is widely used for hotels, recreation grounds, bazaars, factories, office buildings, warehouses and families.
Description
The utility model relates to a kind of electric disaster hidden-trouble monitoring alarm.
Along with the raising of expanding economy and living standards of the people, household electrical appliance are on the increase, and power consumption also constantly increases.Original electric wiring can not adapt to overload operation, cause the line insulation layer to accelerate aging, breakage and the accident of short-circuit fire happens occasionally, public places of entertainment such as shop, karaoke halls, nightclub particularly, use nonconforming lead during finishing, amateur again electrician installs, wiring is unreasonable, joint is unreliable, loose contact; Fake and forged electric wire electric equipment products become maximum disaster hidden-trouble; Chemical industry, weaving, inflammable and explosive dangerous goods workshop and warehouse etc. prevent that electrical fire is particularly important.The conventional method that prevents electrical fire is, adopts fuse and overcurrent switch etc., but all is just to work when short circuit, then can not report to the police for the disaster hidden-trouble of hiding.Disclose many fire-alarms in the existing patent documentation, but these alarms all are the naked light warning devices, promptly when fire took place, transducer was reported to the police according to the temperature in the monitoring range, smog, flame.For electrical fire in the transducer monitoring range or disaster hidden-trouble can't not reported to the police.Though new and high technologies such as infrared, sonac, computer can be monitored electric disaster hidden-trouble, can not protect and invest big automatically, monitoring range is limited, is difficult to popularize.
The purpose of this utility model is: provide a kind of and both can find electric disaster hidden-trouble, again the automatic early-warning protector of may command electrical fire generation.
The technical solution of the utility model is: electrical fire automatic early-warning protector, have shell, lead tie point, transformer and printed circuit board (PCB), alarm are arranged in the shell, rectification on the circuit board, filtering, voltage stabilizing circuit connect the integrated package of conversion of signals effect, on the charged power circuit, be connected to temperature sensor, power cable is wrapped in the appearance of transducer, connect integrated package by temperature sensor and form electronic switch, chip output connects alarm, when the chip output potential change, the alarm sound and light alarm.Also be connected in series a fusing transducer on the power line, and power lead is wound in the surface, lead is wound in the temperature sensor appearance then; The temperature of temperature sensor is 60 ℃～100 ℃ warnings.Between integrated package and alarm, be provided with coded transmitter, the corresponding wireless receiver that is provided with reflector; In signaling conversion circuit, be provided with two integrated packages, second integrated package input termination one variable potentiometer.
The utlity model has following advantage: 1. transducer can be according to fire prevention critical temperature and the safe operation current parameters set, and is capable of automatic alarm or directly control the disconnection of power supply, can prevent effectively that electrical fire from taking place, rather than just warning after the breaking out of fire; 2. this product serial connection monitoring is not automatically on the line influenced by the power load size, and the power consumption circuit all can be installed, and not limited by environment and monitoring range; The overload operation of 3. aging and new line for wire insulation, all capable of automatic alarm and protection, sensitive reliable; 4. because sending and receiving apparatus arranged, at a distance, on a large scale, the power consumption equipment of high-altitude high temperature position, need not make an inspection tour; 5. cost low, easy to use, be convenient to popularize.
Accompanying drawing is embodiment of the present utility model.
Fig. 1 is this product structure schematic diagram;
Fig. 2 is this product side cutaway view;
Fig. 3 is this product circuit structural representation.
Below in conjunction with accompanying drawing the utility model is elaborated.
From Fig. 1, Fig. 2 as can be known, electrical fire early warning protector has shell 1, the shell internal upper part has 4 wire joinings 4, transformer 2 (also can adopt capacitance decompression), temperature sensor 5 and fusing transducer 6 are arranged under it, integrated package 9 and alarm 7, variable potentiometer 10 are housed on the circuit board 8, reflector 3 is positioned at the below of transformer 2, perpendicular to circuit board 8.
As can be seen from Figure 3, charged power has input and output totally 4 wire joinings 4, is connected to 2 indicator lights between live wire and zero line.Twine again on temperature sensor 5 in appearance live wire serial connection fusing transducer 6 backs.Temperature sensor 5 connects control circuit 13.Control circuit 13 power supplys are taken from controlled circuit, through transformer 2 step-downs, bridge rectifier, capacitor filtering, voltage-stabiliser tube W
1Power to integrated package 9 after the voltage stabilizing.As reducing this small product size, improve product stability, can use capacitance decompression instead without transformer 2.The safe operation latent heat temperature of setting is passed through R more than 60 ℃ the time
2The input integrated package, 2 of control integrated package
#The pin current potential, after changing by 3
#Pin output, variation of temperature changes the input and output terminal potential of integrated package.Chip output is connected with alarm 10 and alarm lamp 11.When sensor temperature reaches the critical value of artificial setting, just sound and light alarm.
Between integrated package 9 and alarm 10, also can connect a coded transmitter 3, with the reflector 3 corresponding wireless receivers that are provided with.Emission is convenient to know warning in the place of 30 meters～100 meters distances with the setting of receiver.Establish 2 integrated packages in signaling conversion circuit, second integrated package imported termination one variable potentiometer 10, is convenient to the output voltage of manual adjustment integrated package, produces sound and light alarm with the temperature extremes value of regulating transducer.
The fusing when limiting temperature of fusing transducer 6 reaches 100 ℃.
This product is serially connected between metering ammeter or mains switch and the transmission line head end, by pilot (or power consumption equipment) latent heat temperature extremes, when conductor temperature reaches more than 60 ℃, just sound and light alarm, do not take measures after the warning,, remove load as power cutoff, reduce load, rectification circuit etc., temperature continues to raise, when reaching 100 ℃ (fire prevention critical limit temperature), the fusing transducer disconnects, automatically outage.
