A low-impact self-separating rod type compression release device

Abstract

The invention discloses a low-impact self-detaching rod type pressing release device. The device comprises two connecting rods, a spring, locking bolts, a locking sleeve, a locking head and a fastening rope; during fastening, pre-tightening force is performed on the fastening rope to clamp the locking sleeve into the locking head, and therefore the connecting rods at the two ends are connected toform a whole part through the locking head and the locking sleeve to achieve a connection bearing function; during unlocking, the constraint of the fastening rope is released, the locking bolts at thetwo ends move towards the middle under the effect of the spring to push the locking sleeve radially towards the outer side, so that the locking sleeve is detached from the locking head, and thereforethe connecting rods at the two ends are disconnected to achieve an unlocking function. According to the device, low impact is achieved to prevent a camera from damage during unlocking, automatic detachment can be achieved after unlocking on the premise that the junction positions of the camera and a main structure of a satellite are not changed, and the normal work of a vibration isolation deviceis ensured.

Description

technical field [0001] The invention relates to the technical field of remote sensing satellites, in particular to a low-impact self-separating rod type pressing and releasing device. Background technique [0002] With the development of remote sensing satellite technology, the imaging accuracy of payloads such as optical imaging cameras on the ground is getting higher and higher, and they are more sensitive to micro-vibration interference. When the satellite is in orbit, various moving parts will inevitably produce vibration interference. After the payload is transmitted, the image will be blurred and the imaging quality will be reduced. In order to reduce this interference, more and more vibration isolation devices are used on the connection interface between the camera and the satellite structure. The connection stiffness is reduced through the vibration isolation device, and the micro-vibration transmitted from the main structure of the satellite to the camera is isolat...

Problems solved by technology

If this method is applied to the camera vibration isolation device, that is, the upper frame is connected with the camera, and the lower frame is connected with the satellite structure. After the explosion bolt is unlocked, the vibration isolation device will also connect the camera and the satellite structure together. The upper frame and the lower frame There is relative movement between them, which will affect the normal operation of the vibration isolation device
