Abstract
The utility model provides a pressure shortage alarm for a fire extinguisher. The pressure shortage alarm comprises a magnetic pointer, a bidirectional thyristor, a button switch, a power supply and an early warning device. The pressure shortage alarm for the fire extinguisher is arranged on a pressure gauge of the fire extinguisher, the magnetic pointer coincides with a pointer of the pressure gauge of the fire extinguisher, the pointer of the pressure gauge of the fire extinguisher can rotate to drive the magnetic pointer to rotate, the power supply is connected with the center of the magnetic pointer and a T2 electrode of the bidirectional thyristor, a negative electrode of the power supply is connected with a negative electrode of the early warning device, a positive electrode of the early warning device is connected with one end of the button switch, the other end of the button switch is connected with a T1 electrode of the bidirectional thyristor, and a G electrode of the bidirectional thyristor is led out to be in contact with the magnetic pointer in rotation. The pressure shortage alarm for the fire extinguisher is arranged on the pressure gauge of the fire extinguisher. If pressure in the fire extinguisher is abnormal, early warning can be sent out right now. Thus, the fire extinguisher can be replaced by people timely, and the situation that the fire extinguisher cannot be used when fire happens is avoided.
Description
Technical field
The utility model relates to fire extinguisher precaution device field, particularly a kind of fire extinguisher undervoltage alarm.
Background technology
Fire extinguisher is the extinguishing device that house and vehicle must be equipped with, and, in case break down,, when fire really comes temporarily, will cause property and the personal damage that can not estimate.Fire extinguisher has in the market all been installed Pressure gauge, and has shown the zone of under-voltage, overvoltage and normal pressure, and people can, by checking the zone of pointed, know namely whether fire extinguisher is in abnormality, thereby change accordingly.But in daily life, people seldom can remove to check fire extinguisher, if fire extinguisher is in under-voltage or overpressure conditions can not be known so easily occur hidden danger at once when needs use, therefore need to predict ahead of time its situation, in order in time fire extinguisher is changed, therefore have the people to expect Pressure gauge is reequiped to remind, but fire-fighting equipment there is strict standard arbitrarily to reequip.
The utility model content
for above problem, the utility model is by a kind of fire extinguisher undervoltage alarm of design, this alarm is arranged on pressure gauge for fire extinguisher, if the fire extinguisher internal pressure occurs abnormal, can send at once early warning, thereby people can in time change fire extinguisher, thereby can prevent from running into the fire fire extinguisher can't use, the utility model provides a kind of fire extinguisher undervoltage alarm, comprise the magnetic pointer, bidirectional thyristor, press button, power supply and precaution device, described fire extinguisher undervoltage alarm is arranged on pressure gauge for fire extinguisher, described magnetic pointer and pressure gauge for fire extinguisher pointer coincide, driving the magnetic pointer when pressure gauge for fire extinguisher pointer rotates rotates, described power supply is connected with the T2 utmost point of magnetic pointer center and bidirectional thyristor, described power cathode is connected with the precaution device negative pole, described precaution device positive pole is connected with press button one end, the described press button other end is connected with the T1 utmost point of bidirectional thyristor, the G utmost point of described bidirectional thyristor touches while drawing for the rotation of magnetic pointer.
As further improvement of the utility model, described precaution device is buzzer or flash lamp, and the utility model can use flash lamp or buzzer so that the related personnel in time finds fire extinguisher is changed, and producer can select corresponding precaution device according to actual needs.
As further improvement of the utility model, described fire extinguisher undervoltage alarm is by clamping mode or the paster mode is arranged on pressure gauge for fire extinguisher, and the mode of clamping is installed and more simply is easy to dismounting, and paster mode cost is lower.
The utility model is a kind of fire extinguisher undervoltage alarm, need not fire extinguisher is reequiped, the utility model alarm is arranged on pressure gauge for fire extinguisher, by magnetic pointer and the interlock of pressure gauge for fire extinguisher pointer, when the pressure gauge for fire extinguisher pointer to under-voltage or overpressure zone, the magnetic pointer is drawn mutually and is carried out early warning after touching with the G utmost point of bidirectional thyristor, and then can in time remind people to change fire extinguisher, thereby can guarantee that fire extinguisher can use at any time.
Description of drawings
Fig. 1 is the utility model circuit diagram;
Member in figure is:
1, magnetic pointer; 2, bidirectional thyristor; 3, press button;
4, power supply; 5, precaution device.
The specific embodiment
Below in conjunction with drawings and Examples, utility model is described in detail:
The utility model is by a kind of fire extinguisher undervoltage alarm of design, this alarm is arranged on pressure gauge for fire extinguisher, and is abnormal if the fire extinguisher internal pressure occurs, can send at once early warning, thereby people can in time change fire extinguisher, thereby can prevent from running into the fire fire extinguisher, can't use.
as a kind of specific embodiment of the utility model, the utility model provides circuit diagram a kind of fire extinguisher undervoltage alarm as shown in Figure 1, comprise magnetic pointer 1, bidirectional thyristor 2, press button 3, power supply 4 and precaution device 5, described fire extinguisher undervoltage alarm is by clamping mode or the paster mode is arranged on pressure gauge for fire extinguisher, the mode of clamping is installed and more simply is easy to dismounting, paster mode cost is lower, described magnetic pointer 1 coincides with the pressure gauge for fire extinguisher pointer, driving magnetic pointer 1 when the pressure gauge for fire extinguisher pointer rotates rotates, described power supply 4 is connected with the T2 utmost point of magnetic pointer 1 center and bidirectional thyristor 2, described power supply 4 negative poles are connected with precaution device 5 negative poles, described precaution device 5 positive poles are connected with press button 3 one ends, described precaution device 5 is buzzer or flash lamp, the utility model can use flash lamp or buzzer so that the related personnel in time finds fire extinguisher is changed, producer can select corresponding precaution device 5 according to actual needs, described press button 3 other ends are connected with the T1 utmost point of bidirectional thyristor 2, the G utmost point of described bidirectional thyristor 2 touches while drawing for 1 rotation of magnetic pointer.
During the utility model work, this device is arranged on pressure gauge for fire extinguisher, the magnetic pointer overlaps with it because gauge hand has ferromagnetism, both link mutually, when the fire extinguisher internal pressure is in overvoltage or under-voltage condition, the pressure gauge for fire extinguisher pointer drives the magnetic pointer and rotates together, the magnetic pointer is touched mutually with the G utmost point exit of bidirectional thyristor, and then generation positive pulse, the conducting bidirectional thyristor, and then the conducting early warning circuit, and then send early warning, until people's discovery situation presses the button the switch shut-off circuit, fire extinguisher is changed.
The above; it is only preferred embodiment of the present utility model; be not the utility model to be done the restriction of any other form, and, according to any modification or equivalent variations that technical spirit of the present utility model is done, still belong to the utility model scope required for protection.
