Description

Technical Field

[0001] The utility model relates to the field of fire extinguishing devices for chemical plants, in particular to a fire extinguishing device for chemical plants. Background Art

[0002] Chemical plants are often faced with fire risks due to their special production environment, which places higher demands on fire extinguishing equipment. The application of traditional fire extinguishing equipment in chemical plants has many limitations, mainly including the following aspects:

[0003] Fire situations in chemical plants are complex and changeable. Traditional equipment often lacks adaptability to different fire source heights and firefighting environments. It is difficult to extinguish fires quickly and effectively by relying on manual operations for high-altitude fire sources that may exist in chemical plants. Close-range firefighting operations pose a great threat to the personal safety of firefighters, and high temperatures and harmful gases may cause serious injuries or even deaths.

[0004] Fire-fighting equipment operating in high-temperature environments requires effective cooling protection measures to prevent the equipment from overheating and damage, but most existing fire-fighting equipment is not equipped with cooling devices.

[0005] Therefore, it is of great significance to design a fire extinguishing device for chemical plants that can improve fire extinguishing efficiency, ensure the safety of firefighters, enhance the adaptability of equipment, and have cooling protection capabilities. Utility Model Content

[0021] The beneficial effects achieved by the utility model are:

[0022] First, when extinguishing a fire, the utility model can remotely control the fire extinguishing angle of the water gun head according to the height of the fire point, and at the same time, the nozzle provided by the solution can be used to cool the device to prevent damage to the device when the temperature is too high, and effectively avoid the damage to firefighters caused by close-range fire extinguishing.

[0023] Second, the connecting ring is connected to the telescopic cylinder, and remote control by a remote controller can make the telescopic cylinder drive the water gun head to adjust the angle, so as to cool down and extinguish fire points at different heights.

[0025] Fourth, a temperature sensor is arranged on the top of the machine body and is connected to the control panel through a data line. When the temperature of the device is too high because it is too close to the ignition point, the temperature sensor transmits a signal to the control panel. After processing the data, the control panel sends the signal through the data line to open the solenoid valve, so that the water sprayed by the nozzle can cool down the device in time, thereby playing a certain protective role for the device.

[0026] Fifth, a driving motor is arranged under the body, and the driving motor is provided with a driving gear, and the driving gear is meshed with the transmission gear.
