Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fire extinguisher for a generator set. Background Art

[0002] The wind power source consists of a wind turbine, a tower supporting the turbine, a battery charge controller, an inverter, a load unloader, a grid controller, a battery pack, etc. The wind turbine includes a wind wheel and a generator. When the wind turbine is in use, it needs to be equipped with safety equipment to ensure that the generator can be extinguished in time with a fire extinguisher in the event of an accidental fire.

[0003] In the prior art, there are two common types of fire extinguishers for generator sets. One is to place a bottled fire extinguisher in a safe area. When personnel discover a fire, they can extinguish the fire of the generator set by operating the fire extinguisher by hand. The current fire extinguishers for generator sets require personnel to discover the fire in time and extinguish the fire with the help of the fire extinguisher. It is impossible to extinguish the fire in time, and the spread of the fire is likely to cause concentrated damage to the generator set, resulting in large economic losses. The second is to use an intelligent monitoring fire-fighting device to monitor the generator set. Once a fire source appears in the generator set, the fire-fighting system automatically extinguishes the fire of the generator set. The projects constructed by the applicant usually use intelligent monitoring fire-fighting devices, but in the project cost review, it was found that the price of intelligent monitoring fire-fighting devices that can be purchased on the market is relatively high, which increases the cost of the project. For this reason, a generator set fire extinguisher is developed to reduce costs. Utility Model Content

When the smoke sensor 13 detects that a fire occurs, the control component controls all the fire extinguishing bottles 3 to open, and the dry powder in the fire extinguishing bottles 3 is sprayed out to extinguish the fire in the generator set.

[0025] In this embodiment, the fire extinguisher bottles 3 are all common fire extinguishers on the market. The fire extinguisher bottles 3 include a bottle body and a circulation valve, a hose and a fire extinguishing nozzle which are sequentially connected to the outlet end of the bottle body. The circulation valve is provided with a pressing handle for controlling the opening and closing of the valve core. By pressing the pressing handle to open the valve core of the circulation valve, the dry powder in the bottle body can be sprayed out through the fire extinguishing nozzle to extinguish the fire. Under normal circumstances, in order to prevent the pressing handle from being pressed by mistake, a safety pin 12 that prevents the pressing handle from being pressed is inserted in the circulation valve. In order to achieve the fire extinguishing effect in this embodiment, the control component needs to pull out the safety pin 12 and press the pressing handle, so that the fire extinguisher bottle 3 can be controlled to extinguish the fire.
