UAV soft fuel tank

Abstract

The invention relates to a soft fuel tank for an unmanned aerial vehicle, which has a soft oil storage container made of non-metallic material. The oil container, the lower part of which is directly connected to an oil supply tank, the inner threaded metal ring of the outer threaded oil filler cap screwed on the oil filler port and the soft oil tank are vulcanized together, and the outer threaded metal ring and the surface with steel balls are made on the oil filler cap Sealed one-way anti-vacuum valve. It has corrosion resistance, vibration resistance and good heat insulation. The ring tube type is used to fix the suspension point, which is directly hung into the structure fixing pin, and the installation and disassembly of the fuel tank is convenient. The fuel filler cap and anti-vacuum valve are ingeniously combined to make the fuel tank more compact. The steel ball surface-sealed one-way anti-vacuum valve on the fuel filler cap ensures that there is no vacuum in the fuel tank during the oil delivery process, so that the oil delivery is smooth. The self-sealing of the soft oil tank surface rubber has changed the traditional sealing method of plugging and clamping.

Description

UAV soft tank technical field The present invention relates to a kind of rubber thin-walled soft fuel tank, especially the rubber soft oil used for storing fuel by small unmanned aerial vehicles box. Background technique [0002] Bladder fuel cells and integral fuel tanks are of different types The fuel tank, the soft fuel tank is a capsule fuel tank. When manufacturing, first make a wooden model, then use nylon cloth, and then apply glue. Its advantage is the advantage of space High utilization rate, good heat insulation and vibration resistance. If the anti-aging paint layer is applied, it can be used for 18 to 24 years. The disadvantage is that the system It takes a long time to build and the cost is high. The soft oil tank in the prior art is to utilize the internationally popular high-grade synthetic material to make through high-frequency welding, and the material becomes It is mainly composed of PVC and polyester. Or a software made of oil-resistant polyur...

AI Technical Summary

Problems solved by technology

Soft oil tank is made of nitrile rubber 5870 matrix material, and it has some deficiencies in itself: 1. because itself is soft

Therefore, it is required that the cabin body of the softened fuel tank is basically complete, and the sealing method is blocked and clamped, which is inconvenient to install and disassemble

②The service life of the soft fuel tank is shorter than that of the metal fuel tank

Use in high temperature air, prone to vacuum state

④Storage and preservation requirements are high, must be suspended in the air, away from the ground and walls

Oil supply is too fast and easy to flow back into the soft oil tank
