Anti-impact protective buoy

Abstract

The invention discloses an anti-impact protective buoy which is used for anti-impact protection of a testing device in a ship explosion impact test. The anti-impact protective buoy comprises an outer drum (2) fixedly arranged on a ship through an energy absorbing support (1), an inner drum (6) sleeved in the outer drum (2), a device platform (13) is arranged in the inner drum (6), and the testing device is arranged on the device platform (13). The anti-impact protective buoy is characterized in that a supporting platform (15) is arranged in the outer drum (2), the inner drum (6) is arranged on the supporting platform (15) through a rubber gasket, the upper end of the inner drum (6) protrudes out of the upper end face of the outer drum (2), a gap full of water is arranged between the inner drum and the outer drum, and a rubber supporting ring 11 is arranged in the gap between a wall face of the upper port of the outer drum (2) and an outer wall face of the inner drum (6). The anti-impact testing buoy can achieve efficient cooling and three-level vibration reduction so as to protect and recycle a testing device.

Description

technical field [0001] The invention relates to the field of protection devices, in particular to an anti-shock protection buoy suitable for the anti-shock protection of test equipment in ship explosion shock tests. Background technique [0002] In the ship explosion impact test, when the live ammunition hits the floating body and explodes, the explosion shock wave and large-area high-temperature flame may damage the test equipment such as acquisition instruments, computers, sensors, and wires, so special protective measures must be taken for the test equipment. Protect equipment with impact guards. [0003] The most notable feature of the impact protection device used for test and test equipment is that it can withstand high temperature and high impact, and can float upright after falling into the water to recover the test equipment and obtain test data. At present, the measure of impact protection for measuring instruments is to arrange the measuring instruments on the bu...

Problems solved by technology

However, the buffer platform only focuses on anti-shock protection, and mainly relies on the shock-resistant isolator for vibration isolation, which requires high requirements for the development or selection of the shock isolator, and the buffer platform lacks protective measures for high-temperature environments and watertight test equipment.
