Unpowered self-separated impact protection device

Abstract

The invention discloses an unpowered self-separated impact protection device, which comprises an upper shell, a probe, a nonmetallic layer, a lower shell, a connecting rod, a clamping mechanism, a bracket, a heavy object block, an upper guide ring, a lower guide ring and a spring, wherein the upper shell, the lower shell and the nonmetallic layer form a three-petal structure; detection equipment is placed in an upper cavity formed by the nonmetallic layer; the heavy object block is placed in a lower cavity formed by the nonmetallic layer; the upper guide ring and the lower guide ring are arranged in concave grooves of the heavy object block up and down; the spring is arranged between the upper guide ring and the lower guide ring in a free state; the upper end of a central rod of the bracket is sleeved on the spring and fixedly connected with the lower end of the spring; and the probe connects the upper shell and the lower shell together, the three-petal assembly of the upper shell andthe lower shell is wrapped on the external circle of the nonmetallic layer, and the clamping mechanism is connected with the bracket and peripherally fixes the bottom surface of the lower shell. The protection device can buffer the impact force when the detection equipment enters the water, and the detection equipment is reliably separated from the protection device.

Description

technical field [0001] The invention relates to an anti-shock protection device, in particular to an unpowered self-separating type anti-shock protection device, which belongs to the technical field of marine exploration equipment. Background technique [0002] At present, when launching detection equipment into the sea from high altitudes, most of them use parachutes to slow down the falling speed of objects to reduce the impact of the water surface when the equipment enters the water to protect the equipment. The resistance reduced by the parachute is limited by the parachute The height of the parachute and the angle when entering the water are limited by many factors, and the price of the parachute is relatively expensive, and the release mechanism between the parachute and the equipment is complicated, so the funds required for the high-altitude delivery equipment are too high. The reliability is not too high, so it is no longer suitable for high-altitude drop detection ...

The resistance reduced by the parachute is limited by the parachute The height of the parachute and the angle when entering the water are limited by many factors, and the price of the parachute is relatively expensive, and the release mechanism between the parachute and the equipment is complicated, so the funds required for the high-altitude delivery equipment are too high. The reliability is not too high, so it is no longer suitable for high-altitude drop detection equipment in the open sea
