Miniature air-compression generator

Abstract

The invention relates to a miniature air-compression generator, comprising a motor body, a shaft sleeve, output wires and a blade. The output wires are connected with the motor body. The motor body includes: a motor housing; a motor shaft, a support, a coil, a magnetic sleeve and a rear cover mounted in the motor housing. The blade is passed through one end of the motor shaft and fitted to the shaft sleeve; the other end of the motor shaft is connected with the support. The coil is mounted on the support. The magnetic sleeve is connected with the motor body via a socket shaft. Two bearing bushes are embedded in the two ends of the inside of the socket shaft. The motor shaft is mounted by being passed through the two bearing bushes. A gap is provided between the motor shaft and each bearingbush. The blade is used herein as a driving component; when the blade is driven by wind to rotate, the motor shaft drives the coil to rotate around the magnetic sleeve, current is output, and power generation is finished. The startup speed and rotation speed are changed by adjusting the blade specification so as to adapt to different flight environments and startup conditions; the requirement onminiaturization can be met. The whole miniature air-compression generator which is of slender cylinder structure is applicable to projectile structures and allows on-projectile space to be conveniently allocated.

Description

technical field [0001] The invention relates to the technical field of missile-borne power supplies, in particular to a micro-generator using air pressure to generate electricity. Background technique [0002] The micro air compressor generator is a new missile-borne power supply solution that uses the wind resistance to drive the blades to generate power for the missile's circuit during flight. The current missile-borne power supply mainly includes thermal batteries, also known as heat-activated reserve batteries. The electrolyte is a non-conductive solid during storage. When in use, an electric ignition head or a firing pin mechanism is used to ignite the heating agent inside, so that the electrolyte melts and becomes an ion conductor. A reserve battery that is activated. The storage time is theoretically unlimited, and actually reaches more than 10 years. Lithium chloride-potassium chloride eutectic is mostly used as the electrolyte, and zirconium and chromic acid powde...

AI Technical Summary

Problems solved by technology

It is precisely because of these shortcomings of thermal batteries that disposable lithium batteries have also begun to be used in some ammunition in recent years. Its miniaturization, standardization, and stable output are superior to thermal batteries, but it also has a fatal weakness, and its storage life is difficult to reach 10 years. If it is stored for more than 10 years, a passivation film will be formed, and the voltage response will lag. At present, only the Israeli TADIRAN brand lithium battery can solve this problem well. The storage life is 20 years without lag, but the price is very high. It is difficult to realize large-scale application, and because it is an imported battery, it does not meet the requirements of localization

In addition, this kind of traditional power supply itself is charged, and there is a risk of short circuit causing fire during the assembly process, and there must be a special control circuit to control the output when in use.
