Description

TECHNICAL FIELD

[0001] The utility model relates to a turbojet fire extinguishing machine, especially a turbojet fire extinguishing machine with telescopic connecting rod. BACKGROUND

[0002] The wind power fire extinguishing machine currently plays an important role in forest fire prevention, and the turbojet fire extinguishing machine is an upgrade. However, due to the defects in the principle of the turbojet fire extinguishing machine, the wind power generated by the turbojet is relatively strong, and the nozzle will generate overheated air, so that the nozzle cannot be used for wind guiding and air outlet like the long nozzle of the ordinary wind power fire extinguishing machine, thus the nozzle of the turbojet fire extinguishing machine is much shorter than that of the ordinary wind power fire extinguishing machine, which makes the distance between the nozzle and the fire source longer when extinguishing the fire, which greatly affects the fire extinguishing effect and causes a lot of energy waste, or the fire fighting personnel hold the short nozzle turbojet fire extinguishing equipment close to the fire source, which makes the fire fighting personnel need to approach the fire source artificially, thus the distance between the fire source and the fire fighting personnel is close, which is easy to cause danger.

[0005] Further, one end of the oil outlet pipe I is connected with the oil outlet, and the other end of the oil outlet pipe I is inserted into one end of the oil outlet pipe II to form a sleeve joint, and the other end of the oil outlet pipe II is inserted into the turbojet air duct from the center of the rear end of the turbojet air duct to be connected with the oil inlet of the turbojet engine, when the outer air port of the front end of the turbojet air duct needs to be stretched to the remote fire target, the oil outlet pipe I and the oil outlet pipe II are stretched and locked by the locking device, and the oil outlet is connected with the oil inlet of the turbojet engine through the oil outlet pipe I and the oil outlet pipe II.

[0006] Further, the locking device comprises a threaded sealing sleeve and a threaded compression sleeve, and the threaded sealing sleeve and the threaded compression sleeve are installed at the joint of the oil outlet pipe I and the oil outlet pipe II, when the oil outlet pipe I and the oil outlet pipe II are stretched, the threaded sealing sleeve is moved to the joint between the oil outlet pipe I and the oil outlet pipe II to seal the joint, and then the threaded compression sleeve is moved to be sleeved outside the threaded sealing sleeve, and the oil outlet pipe I and the oil outlet pipe II are locked by the cooperation between the inner thread of the threaded compression sleeve and the outer thread of the threaded sealing sleeve.

[0007] Further, the oil outlet pipe I and the oil outlet pipe II both comprise an inner PVC pipe, and an outer metal pipe is wrapped outside the inner PVC pipe.

[0008] Further, the threaded sealing sleeve is a silica gel sleeve, and the threaded compression sleeve is made of PE material.

[0010] Further, the turbojet controller and the control port of the turbojet engine are wirelessly connected.

[0011] This utility model has the following beneficial effects: By adopting the above technical solution, this utility model modifies the intermediate connecting rod of the turbojet fire extinguisher, changing it into a telescopic connecting rod. The branch pipe I and branch pipe II of the telescopic connecting rod are respectively the oil outlet pipe I and oil outlet pipe II. The oil outlet pipe I and oil outlet pipe II are connected together to form a telescopic connection. The oil outlet is connected to the oil supply port of the turbojet engine through oil outlet pipe I and oil outlet pipe II. This allows firefighters to extend the connecting rod when the turbojet nozzle is relatively short and the range is insufficient. The retractable connecting rod extends the turbojet duct directly into the base of the fire source, increasing the extinguishing distance of the turbojet fire extinguisher. This avoids the need for personnel to approach the fire source, preventing wasted airflow during extinguishing, reducing energy loss in the turbojet engine, and improving extinguishing efficiency. It also prevents safety accidents caused by firefighters getting too close to the fire source, improving safety. Furthermore, the increased distance between the turbojet engine and firefighters reduces noise impact. Both the oil outlet pipe I and oil outlet pipe II of this invention include an inner PVC pipe covered by an outer metal pipe. This not only increases the strength of oil outlet pipes I and II, preventing breakage, but also improves the smoothness of oil delivery. The turbojet controller and the turbojet engine control port of this invention are wirelessly connected, simplifying the connection structure and facilitating control. The threaded sealing sleeve of this utility model is a silicone sleeve, and the threaded clamping sleeve is made of PE material. When oil outlet pipe I and oil outlet pipe II are extended, the threaded sealing sleeve moves to the joint between oil outlet pipe I and oil outlet pipe II to seal the joint. Then, the threaded clamping sleeve is moved and placed on the outside of the threaded sealing sleeve. The connection between oil outlet pipe I and oil outlet pipe II is locked by the mating connection between the inner thread of the threaded clamping sleeve and the outer thread of the threaded sealing sleeve. This not only improves the sealing performance of oil outlet pipe I and oil outlet pipe II after they are extended, but also avoids misalignment of oil outlet pipe I and oil outlet pipe II after they are extended, thus improving the stability of use.
