Embodiment Construction

[0022] A cubesat release device, used for the sequential release of multiple cubesats, mainly includes a satellite cabin, a first spring, a push plate, a cubesat, a pressing block, a pin shaft, a slider, a slide bar, a second spring, a moving Frame, push rod, third spring, sliding lead screw, motor, stop lever, satellite cabin is used as the carrier of cube star, and described cube star is all arranged in the satellite cabin, and wherein one end in the satellite cabin is provided with satellite cabin release port, The other end is provided with a first spring and a push plate that push the cubesat along the horizontal direction. N cubesats can be set in the satellite cabin, and the number ranges from 4 to 8. The cubesat that is close to the release port is used as the cubesat to be released. The cube stars are arranged horizontally from one end of the release port to the other end in sequence.

[0023] Before the cubesat is released, all the cubesats are fixed in the satellite...

Abstract

The invention discloses a cubesat release device. The device comprises a satellite cabin, a first spring, a push plate, cubesats, a pressing block, a pin shaft, a sliding block, a sliding rod, a second spring, a moving frame, a push rod, a third spring, a sliding lead screw, a motor and a stop rod. A plurality of cubesats are fixed in the satellite cabin and the to-be-released cubesat is limited by utilizing a pressing plate; when the cubesat is released, a moving frame and the pressing plate are driven by the motor to release the cubesats; and meanwhile, the cubesat released in the second syn-position is limited by the stop rod, a release device with a cubesat intermittent release function is achieved, the structure is stable, and the intermittent release function can be achieved.

Description

technical field [0001] The invention relates to a cube star release device, which belongs to the technical field of space mechanisms. Background technique [0002] At present, the known CubeSat release devices are divided into two types: pyrotechnic release devices and non-pyrotechnic release devices. There is an impact when the pyrotechnic release device is separated, and the satellite has a large vibration during separation, which affects the angular velocity of the satellite separation, and is rarely used. Non-pyrotechnic driving devices use two types of driving devices to release, one type is driven by the properties of materials, such as memory alloys, thermal cutting, etc. This type of unlocking takes a long time and consumes a lot of power, and thermal cutting is not conducive to multiple times on the ground. One type of test is to use a mechanism device to release, and electromagnetic unlocking is mostly used. This type of unlocking is low in cost and can be tested ...
