Abstract
Claims
1. An automatic sensing fire extinguishing device for installation on at least one fire extinguisher, the fire extinguisher including an actuating handle, comprising: A sensor is used to sense an environmental condition. When the sensor detects that the environmental condition is a fire, the sensor sends out a fire signal. An automatic control system is connected to the sensor to receive the fire signal and to issue a braking signal upon receiving the fire signal. The system also includes a braking mechanism connected to the automatic control system for receiving the braking signal. This mechanism includes a slider, a positioning rod, and a braking device. The slider rests against the trigger handle and can slide up and down on the positioning rod. Upon receiving the braking signal, the braking device brakes the slider to press the trigger handle downwards on the positioning rod. The automatic fire-fighting sensing device further includes a connecting pipe, a plurality of capacity sensors, and a warning light. The connecting pipe is connected to the fire-fighting fuel output pipes of a plurality of fire extinguishers. Each capacity sensor senses the capacity of each fire extinguisher. When the automatic control system receives the fire signal, it first issues a braking signal to activate a first fire extinguisher. If the automatic control system determines, based on the corresponding capacity sensor, that the first fire extinguisher's fuel is depleted, it then issues another braking signal to activate a second fire extinguisher, until the sensor determines the fire situation has been resolved. Furthermore, when any of the capacity sensors detects that the fire extinguisher's capacity has reached a refill standard, the automatic control system will send a signal to the warning light for display.
2. The automatic sensing fire-fighting device as described in claim 1, wherein the fire extinguisher and the braking mechanism are housed in a housing.
3. The automatic sensing fire-fighting device as described in claim 2, wherein a plurality of pulleys are installed at the bottom of the housing.
4. The automatic sensing fire-fighting device as described in claim 2, wherein a push handle is installed at one end of the housing.
5. The automatic sensing fire extinguishing device as described in claim 1, wherein the fire extinguisher is a carbon dioxide fire extinguisher, a foam fire extinguisher, a dry powder fire extinguisher, a wet powder fire extinguisher, a haloalkane fire extinguisher, or a fine water mist fire extinguisher.
6. The automatic sensing fire-fighting device as described in claim 1, wherein the sensor is a temperature sensor, an infrared sensor, or a smoke sensor.
7. The automatic sensing fire-fighting device as described in claim 1, wherein the slider further includes a pressing member.
8. The automatic sensing fire-fighting device as described in claim 1, wherein the braking device is an electromagnet, a pneumatic cylinder, a hydraulic cylinder, or a temperature-sensing spring.
9. The automatic sensing fire extinguisher as described in claim 1, wherein the fire extinguisher is placed horizontally and can be stacked upwards.
10. The automatic sensing fire-fighting device as described in claim 1, wherein the plurality of capacity sensors are weight sensors, electronic scales or pressure sensors.
