Abstract
An outdoor electric appliance alarm device is provided, which is characterized in that: the utility model comprises a doorbell (10), a first resistance (R1), a second resistance (R2) and a dynatron (Q). The doorbell (10) is provided with a doorbell earth wire (11), a doorbell trigger end (12) and a doorbell battery anode (13); the doorbell power anode (13) is connected with one end of the first resistance (R1) and a first end connection (21) of the electric appliance; the other end of the first resistance (R1) is connected with the doorbell trigger end (12) and a collector of the dynatron (Q); a base of the dynatron (Q) is connected with one end of the second resistance (R2); the other end of the second resistance (R2) is connected with a second end connection (22) of the electric appliance; the doorbell earth wire (11) is connected with an emitter of the dynatron (Q).
Description
Technical field:
The utility model relates to warning device, more specifically relates to the warning device of outdoor electrical equipment.
Background technology:
Because need of work, there have many electrical equipment to be installed in to be outdoor, can increase greatly and be installed in the stolen possibility of outdoor electrical equipment.People's ways of addressing this issue mainly sets a watch on now, and this has improved cost on the one hand, and on the other hand, the time of concentration of people's notice is limited after all, even if there is the people to guard, the safety of outdoor electrical equipment also differs and is guaranteed surely.
Summary of the invention:
The purpose of this utility model is: a kind of outdoor electrical equipment warning device is provided.This warning device is linked to each other with outdoor electrical equipment, and when outdoor electrical equipment existed, warning device did not ring; When outdoor electrical equipment was stolen, warning device was reported to the police.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of outdoor electrical equipment warning device is by doorbell, first resistance R
1, second resistance R
2Form with triode Q.Doorbell has doorbell ground wire, doorbell trigger end and doorbell anode three interfaces, doorbell positive source and first resistance R
1An end and electrical equipment first link connect first resistance R
1The other end be connected the base stage of triode Q and second resistance R with the collector of doorbell trigger end and triode Q
2An end connect second resistance R
2The other end be connected with electrical equipment second link, the doorbell ground wire is connected with the emitter of triode Q.
The utility model has the advantages that: this warning device is linked to each other with outdoor electrical equipment, and when outdoor electrical equipment existed, warning device did not ring; When outdoor electrical equipment was stolen, warning device is reported to the police, and was stolen to prevent outdoor electrical equipment.
Description of drawings:
Synoptic diagram when Fig. 1 uses for the utility model is a structural representation of the present utility model in the wherein empty frame.
Wherein: 10 is that doorbell, 11 is that doorbell ground wire, 12 is that doorbell trigger end, 13 is that doorbell anode, 20 outdoor instruments, 21 are that electrical equipment first link, 22 is electrical equipment second link, R
1Be first resistance, R
2Be that second resistance, Q are triode.
Embodiment:
As shown in Figure 1, a kind of outdoor electrical equipment warning device is by doorbell 10, first resistance R
1, second resistance R
2Form with triode Q.Doorbell 10 has doorbell ground wire 11, doorbell trigger end 12 and doorbell anode 13 3 interfaces, doorbell positive source 13 and first resistance R
1An end and electrical equipment first link 21 connect first resistance R
1The other end be connected the base stage of triode Q and second resistance R with the collector of doorbell trigger end 12 and triode Q
2An end connect second resistance R
2The other end be connected with electrical equipment second link 22, doorbell ground wire 11 is connected with the emitter of triode Q.
The course of work of the present utility model is: electrical equipment first link 21 and electrical equipment second link 22 are connected respectively on the outdoor electrical equipment 5, make it to form path.When outdoor electrical equipment 5 exists, there is electric current to pass through between electrical equipment first link 21 and electrical equipment second link 22, this electric current injects the base stage of triode Q, triode Q conducting, doorbell trigger end 12 is a low level, doorbell does not ring; When outdoor electrical equipment 5 was stolen, electrical equipment first link 21 disconnected with electrical equipment second link 22, does not have electric current to pass through between the two, and triode Q ends, and doorbell trigger end 12 be a high level, and doorbell rings, i.e. warning.
