Onboard fire extinguishing agent storage device

Abstract

The invention discloses an onboard fire extinguishing agent storage device. The device comprises a top end socket, a box body and a bottom end socket, a first reinforcing rib plate integrated with thetop end socket is arranged on the inner wall of the top end socket, and a first screwed joint for assembling a liquid injection valve, a second screwed joint for assembling a pressure balancing device and a third screwed joint for assembling an oil dipstick are welded on the top end socket. A second reinforcing rib plate integrated with the box body is arranged on the inner wall of the box body,a handle is arranged on the outer wall of the box body, and a liquid connector is welded to the lower portion of the box body. A third reinforcing rib plate integrated with the bottom end socket is arranged on the inner wall of the bottom end socket, a cleaning opening provided with a plug is welded to the bottom of the bottom end socket, and a mounting base integrated with the bottom end socket is further arranged on the outer bottom wall of the bottom end socket. The device meets the requirement for structural strength, repeated filling of fire extinguishing agents is achieved, waste causedby frequent replacement of disposable plastic barrels is avoided, and the manufacturing cost is saved.

Description

technical field [0001] The invention relates to the technical field of fire extinguishing systems of large seaplanes, in particular to an airborne fire extinguishing agent storage device. Background technique [0002] The storage tank storing fire extinguishing agent is a main part in the fire extinguishing system of large-scale water fire extinguishing aircraft. When fire extinguishing is required, in order to enhance the fire extinguishing effect, the fire extinguishing agent in the storage tank is usually output into water to dilute, and then spray water at high altitude to extinguish the fire. At present, most of the storage tanks for storing fire extinguishing agents are disposable plastic barrels, which need to be fixed in the aircraft cabin during use. After the fire extinguishing agent in the disposable plastic barrel is used up, it is necessary to remove the plastic barrel from the fixed place and reinstall a new disposable plastic barrel. It is very inconvenient t...

AI Technical Summary

Problems solved by technology

After the fire extinguishing agent in the disposable plastic barrel is used up, it is necessary to remove the plastic barrel from the fixed place and reinstall a new disposable plastic barrel. It is very inconvenient to replace the disposable plastic barrel so frequently; Permanent plastic buckets will be subject to the vibration and overload impact of the aircraft, and need to have high structural strength and good product quality, so the cost of disposable plastic buckets is relatively high, and the cost of frequent replacement of disposable plastic buckets is very high
