Technical Field
The invention relates to a cover opening device of equipment for air drop to the water surface, in particular to an underwater cover opening device.
Background
The marine measuring instrument is one kind of marine measuring instrument for measuring the environment element in water area to be measured. After some airborne throw-away equipment falls into water, one part falls into an environmental element in a depth measurement position of water depth, and the other part floats on the water surface to receive data measured by underwater equipment and send the data. In the air drop process, the part to be in the depth of water is subjected to the largest impact, and although the airborne throwing-type equipment is hung with the parachute, the part to be in the depth of water is subjected to small impact. In order to protect the part of equipment, some equipment is put into a packaging box integrally, and the equipment is separated from the packaging box after falling into water. However, the method causes overlarge whole volume, serious consumable materials and increases the difficulty of air drop.
At present, a common method is to add an end cover at the lower end of the device, so that impact force is applied to the end cover when the device falls into water, and then the end cover is released. The method for releasing the end cover comprises explosion bolt type, electric control type and the like. The safety of transportation and storage is low by adopting the explosion bolt type, and equipment is easily damaged by explosion; by adopting the electric control type, if the impact is larger, the end cover part is deformed, and the end cover cannot be opened. In addition, both modes need to consider sealing, and design and installation difficulties are increased.
Therefore, it is important to design a simple and reliable underwater uncapping mechanism.

After the whole device touches water, the device 7 to be released can be smoothly opened and released.
One end of the pin shaft 1, which is contacted with the pressing block 4, is spherical, so that friction force is reduced conveniently.
The second shaft hole 2-1 of the end cover 2 is in an oblong shape in the direction of the central axis of the outer cylinder 6, so that impact force applied to the end cover 2 when water enters the pin shaft 1 is avoided.
The pressing block 4 is a pressing block with a two-step ladder-shaped notch 4-1, and the height of the upper end surface of the pressing block 4 is higher than that of the position where the pin shaft 1 is located, so that the pressing block can be conveniently and well pressed on the upper end surface of the pressing block 4 after the equipment 7 to be released is released, and the pressing block can move downwards.
When the release equipment 7 is not released, the spherical end of the pin shaft 1 is pressed on the pressing block 4 by the elastic force of the small spring 5, and the other end sequentially passes through the end cover 2 and the shaft hole of the outer cylinder 6; one end of the big spring 3 is propped against the bottom end face of the inner side of the end cover 2, and the other end presses the pressing block 4 on the edge of the pin shaft 1, so that the position of the pressing block 4 is limited by the pin shaft 1 and the big spring 3; one end of the end cover 2 is abutted against the lower end edge of the outer cylinder 6, so that the position of the end cover 2 is limited by the pin shaft 1 and the outer cylinder 6.
After falling into water, when the equipment 7 to be released is released, the equipment 7 to be released is pressed on the upper end face of the pressing block 4, the pressing block 4 moves downwards under the action of gravity of the equipment 7 to be released, after a certain distance of movement, the spherical end of the pin shaft 1 is separated from the original contact surface of the pressing block 4, and the two pin shafts 1 move towards the central axis direction of the outer cylinder 6 under the action of the small spring 5 and are separated from the shaft hole of the outer cylinder 6.
