Description

TECHNICAL FIELD

[0001] The utility model relates to an automatic tracking fire extinguishing device, in particular to a novel steam turbine generator automatic tracking quick fire extinguishing device. BACKGROUND

[0002] The existing fire-fighting water pipe device installed in the steam turbine generator is a safety measure taken to protect the stator and rotor inside the generator from fire caused by faults, prevent the internal fire of the generator from spreading and expanding to cause the generator set to be scrapped, and greatly increase the operation and maintenance cost of the company.

[0003] In order to prevent internal leakage of the fire valve, the existing fire-fighting water pipe valve joint on both sides of the generator is not hard connected with the fire valve in the fire-fighting water tank near the steam turbine generator, and the steam turbine generator fire-fighting extinguishing device cannot be connected as a backup. Once a fire hazard occurs inside the generator, the operator needs to quickly disconnect the generator, run to the fire-fighting water tank to take out the fire hose, run to the generator fire-fighting water pipe to connect, then open the fire-fighting water valves on both sides of the generator, and then open the fire-fighting valves in the fire-fighting water tanks on both sides of the generator to put out the fire. This seriously delays the best opportunity to extinguish the internal fire of the generator, and to some extent, there is a safety risk.

[0004] If a large amount of fire-fighting water enters the generator interior for emergency rescue and fire extinguishing, it is very unfavorable to the electrical insulation of the stator and rotor, and even poses a safety risk and safety hazard to the fire extinguishing operator. SUMMARY

[0005] To solve the above problems, the utility model provides a novel steam turbine generator automatic tracking quick fire extinguishing device, which can automatically control the carbon dioxide gas to extinguish the fire inside the engine when the generator interior is sensed to have a fire, solve the problems of complex fire emergency rescue, slow response speed, and safety hazard of fire-fighting water to the internal electrical devices of the generator, and the specific technical scheme is as follows:

[0007] Further, a carbon dioxide buffer tank is arranged between the carbon dioxide pipeline gas inlet end and the carbon dioxide main pipe, and the carbon dioxide buffer tank pipe is communicated with the carbon dioxide main pipe through an inlet valve.

[0008] The carbon dioxide buffer tank can stabilize the carbon dioxide gas source, so that the carbon dioxide gas emitted by the fire extinguishing device is more stable, and the fire extinguishing effect is improved.

[0009] Further, the carbon dioxide pipeline is further provided with a first manual valve and a second manual valve, the first manual valve is located between the carbon dioxide buffer tank and the interlocking switch valve, and the second manual valve is located between the interlocking switch valve and the fire extinguishing device.

[0011] The purpose of arranging the carbon dioxide bypass pipeline and the bypass switch valve is that when the interlocking switch valve fails during operation, carbon dioxide gas can be transported through the carbon dioxide bypass pipeline for fire extinguishing, so that the risk that carbon dioxide gas cannot be transported to the fire extinguishing device due to the failure of the interlocking switch valve is avoided.

[0012] Further, the fire extinguishing device comprises a flame sensor and a fire extinguishing nozzle, and the flame sensor is electrically connected with the central control fire host.

[0013] Further, the flame sensor is installed at a position opposite to the air outlet of the steam turbine generator.

[0014] The fire extinguishing device is at least one, and a plurality of fire extinguishing devices can be arranged.

[0015] Further, the central control room fire host further comprises an alarm device, and when the flame sensor senses that the steam turbine generator is on fire, the alarm device issues an alarm.

[0017] The flame sensor and the interlocking switch valve are interconnected through the central control room fire host, when the fire in the generator is sensed, the fire extinguishing instruction is sent, the interlocking switch valve is automatically opened to quickly put out the fire in the generator, the fire emergency rescue ability is improved, and the fire extinguishing time is shortened.

[0018] 2. The carbon dioxide bypass pipeline and the bypass switch valve arranged on the carbon dioxide pipeline can avoid the risk that carbon dioxide cannot be transported to the fire extinguishing device for fire extinguishing due to the failure of the interlocking switch valve.

[0019] 3. The fire extinguishing agent is changed from fire-fighting water to carbon dioxide gas for extinguishing the fire in the generator, and the electrical device safety hazard caused by the fire-fighting water for extinguishing the fire in the generator is eliminated. DRAWINGS
