[0025] The following details the embodiments, examples of which are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model and should not be construed as limiting the present utility model.
[0026] The following describes the safety sign alarm circuit and the electronic alarm safety sign of the present embodiment with reference to the drawings.
[0027] Figure 1 It is a schematic structural diagram of the safety sign alarm circuit of the embodiment of the present utility model. As Figure 1As shown in the figure, the safety sign alarm circuit 10 includes: a battery E, an acoustic alarm unit, an optical alarm unit, a thyristor Q, a resistor R, a first lead terminal A1, and a second lead terminal A2. The acoustic alarm unit and the optical alarm unit are connected in series to form an alarm module. The acoustic alarm unit is a buzzer F, and the optical alarm unit is a light-emitting diode D. One end of the buzzer F is connected to the positive pole of the battery E, the other end of the buzzer F is connected to the anode of the light-emitting diode D, and the cathode of the light-emitting diode D is connected to the anode of the thyristor Q. The cathode of the thyristor Q is connected to the negative pole of the battery E. The first end of the resistor R is connected to the positive pole of the battery E, the second end of the resistor R is connected to the gate of the thyristor Q, and the gate and cathode of the thyristor Q are also respectively connected to the first lead terminal A1 and the second lead terminal A2.
[0028] In this embodiment, the thyristor Q is an SCR100-6 type thyristor, the battery E is a rechargeable battery, and the resistance value of the resistor R is 1 kΩ.
[0029] The working principle of the safety sign alarm circuit 10 is as follows:
[0030] When the first lead terminal A1 and the second lead terminal A2 are in contact with the metal part of the external device housing, the first lead terminal A1 and the second lead terminal A2 are connected, the gate branch Z of the thyristor Q is short-circuited, there is no current control signal in the gate branch Z, and the alarm branch where the thyristor Q is located is in an open state. The current output by the battery E starts from the positive pole, passes through the resistor R, and returns to the negative pole of the battery. At this time, when there is current when the first lead terminal A1 and the second lead terminal A2 are connected, the buzzer F and the light-emitting diode D do not emit acoustic and optical alarms.
[0031] When the first lead terminal A1 and the second lead terminal A2 are disconnected, the current output by the battery E passes through the gate branch Z of the thyristor Q, that is, the current signal passing through the gate branch Z controls the thyristor Q to conduct, the branches where the buzzer F and the light-emitting diode D are located are conducted, and the buzzer F and the light-emitting diode D emit acoustic and optical alarms.
[0032] Optionally, the safety sign alarm circuit further includes a switch K. One end of the switch K is connected to the first end of the alarm module, and the other end of the switch K is connected to the positive pole of the battery E.
[0033] When the safety sign alarm circuit 10 needs to be stored, after it is removed, the switch K can be disconnected to turn off the entire electronic circuit.
[0034] Furthermore, the present invention also provides an electronic alarm safety sign 100, including the above-mentioned safety sign alarm circuit 10.
[0035] Figure 2 It is a front view schematic diagram of the electronic alarm safety sign according to the first embodiment of the present invention.
[0036] As shown in Figure 2 the figure, the electronic alarm safety sign 100 further includes a housing 20 and a magnet 30. The alarm circuit 10 of the safety sign is arranged inside the housing 20, and the first lead terminal A1 and the second lead terminal A2 of the alarm circuit 10 of the safety sign are arranged outside the housing 20. The magnet 30 is arranged outside the housing 20, and the number of the magnets 30 is one, and the magnet 30 is specifically arranged at the center position of the housing 20. When the magnet 30 is adsorbed on a metal device, both the first lead terminal A1 and the second lead terminal A2 are in contact with the metal device, and the first lead terminal A1 and the second lead terminal A2 are connected.
[0037] Figure 3 It is a front view schematic diagram of the electronic alarm safety sign of the second embodiment of the present utility model.
[0038] As shown in Figure 3 the figure, the electronic alarm safety sign 100 further includes a housing 20 and a magnet 30. The alarm circuit 10 of the safety sign is arranged inside the housing 20, and the first lead terminal A1 and the second lead terminal A2 of the alarm circuit 10 of the safety sign are arranged outside the housing 20. The magnet 30 is arranged outside the housing 20, and the number of the magnets 30 is four, and the four magnets 30 are arranged at the four corners of the housing 20. When the four magnets 30 are adsorbed on a metal device, both the first lead terminal A1 and the second lead terminal A2 are in contact with the metal device, and the first lead terminal A1 and the second lead terminal A2 are connected.
[0039] Specifically, the electronic alarm safety sign 100 can be relatively firmly adsorbed on the outer shell of a metal device by the magnets 30 at the four corners or the center position. Then, there is a simple electronic circuit inside the electronic alarm safety sign 100. When the electronic alarm safety sign 100 is adsorbed on the outer shell of a metal device, the first lead terminal A1 and the second lead terminal A2 form a circuit through the metal part of the device shell. When the first lead terminal A1 and the second lead terminal A2 are connected, the warning light, that is, the light-emitting diode D and the buzzer F, do not work. When the electronic alarm safety sign 100 falls abnormally due to an external force or is taken away abnormally, the first lead terminal A1 and the second lead terminal A2 are disconnected from the metal part of the device shell, and the warning light, that is, the light-emitting diode D flashes, and the buzzer F alarms.
[0040] Finally, a switch K is provided in the alarm circuit 10 of the safety sign. When the electronic alarm safety sign 100 is retrieved normally, the switch K can be turned off to turn off the entire electronic circuit, and the sound and light alarm does not work, which is convenient for storage.
[0041] In summary, the innovation of the present utility model lies in using a magnet to adsorb the electronic alarm safety sign on the metal parts of equipment such as power switches, isolating switches, circuit breakers, valves, etc. It is more firm than a hanging rope and is not easily lost. At the same time, by means of the metal part of the equipment shell, a circuit is formed. After the sign is hung, the circuit is energized. Once the electronic alarm safety sign drops abnormally or is not collected normally, the circuit where the alarm module in the electronic alarm safety sign is connected, and the electronic alarm safety sign emits an audible and visual alarm, thereby solving the problem of no alarm after the safety sign is lost, and improving the safety during the production of power production enterprises; compared with the hanging rope of the traditional sign, the electronic alarm safety sign of the present utility model is easier to be hung on the equipment shell. The traditional hanging rope can only be hung when there are hook-shaped protrusions on the equipment shell, and it is difficult or not firm to hang on a smooth shell. The electronic alarm safety sign of the present utility model can be more conveniently hung on the equipment shell through the magnets at the four corners or the center position; compared with the traditional sign, the electronic alarm safety sign of the present utility model will not be abnormally dropped or lost due to factors such as strong wind and rainfall outdoors like the hanging rope sign, and will not cause safety risks due to the loss of the sign.
