Description
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
An airborne jettisonable marine measuring instrument is thrown to sea surface by an aircraft to measure environmental elements of a water area to be measured. After some airborne jettison type equipment falls into water, one part of the airborne jettison type equipment falls into the environment elements in the measuring depth at the water depth, and the other part of the airborne jettison type equipment floats on the water surface to receive and send data measured by the underwater equipment. In the air-drop process, the part to be deep in water is impacted the most, and although the airborne jettisonable equipment can be used for hanging the parachute, the aerial jettisonable equipment still can be impacted slightly when entering water. In order to protect the part of the equipment, some equipment is integrally placed in a packaging box, and the equipment is separated from the packaging box after falling into water. However, this method results in an excessively large overall volume, high material consumption and increased air drop difficulty.
At present, the common method is to add an end cover at the lower end of the equipment, so that the impact force when the equipment falls into water acts on the end cover, and then the end cover is released. Methods for releasing the end cap include an explosive bolt type, an electric control type, and the like. The safety of transportation and storage by adopting an explosive bolt mode is low, and equipment is easily damaged by explosion; and if the impact is large, the end cover is partially deformed and cannot be opened. In addition, sealing needs to be considered in both modes, and the design and installation difficulty is increased.
Therefore, it is very important to design a simple and reliable underwater lid opening mechanism.

the hinge pins, the first shaft holes and the second shaft holes are in one-to-one correspondence, the hinge pins are cross-like, one ends of the hinge pins sequentially penetrate through the small springs, the second shaft holes and the first shaft holes and are arranged at the stepped notches of the pressing block, the other ends of the hinge pins are abutted against the pressing block, and therefore the end cover position is limited by the hinge pins and the outer barrel, and the pressing block position is limited by the hinge pins and the large springs; after the pressing block is pressed for a certain distance, the pin shaft can move towards the central axis direction of the outer cylinder under the action of the small spring to be separated from the outer cylinder and the end cover.
Preferably, the compression elasticity of the large spring is greater than the sum of the inertia force and the gravity of the pressing block when the whole device contacts water, but is less than the sum of the gravity of the device to be released and the gravity of the pressing block in the water; the compression elasticity of the small spring is larger than the friction force between the pin shaft and the shaft holes of the end cover and the outer barrel.
Preferably, one end of the pin shaft, which is in contact with the pressing block, is spherical.
Preferably, the second shaft hole of the end cover is oblong in the central axis direction of the outer cylinder.
Preferably, the height of the upper end face of the pressing block is higher than that of the position of the pin shaft.

Referring to fig. 1 and 2, the present embodiment provides an underwater lid opening device, which includes an outer cylinder 6, an end cover 2, a pressing block 4, a large spring 3, a pin 1 and a small spring 5; the end cover 2 is
One end of the end cover 2 abuts against the bottom end edge of the outer cylinder 6, at least two shaft holes I6-1 are formed in the outer cylinder 6, and a shaft hole II 2-1 is formed in the position, corresponding to the shaft hole I6-1, of the upper portion of the end cover 2; the pressing block 4 and the large spring 3 are sequentially arranged in the end cover 2 from top to bottom, and a step-shaped notch 4-1 is formed in the periphery of the pressing block 4; the hinge pin 1, the first shaft hole 6-1 and the second shaft hole 2-1 are in one-to-one correspondence, the hinge pin 1 is cross-like, one end of the hinge pin 1 sequentially penetrates through the small spring 5, the second shaft hole 2-1 and the first shaft hole 6-1 and is placed in the stepped notch 4-1 of the pressing block 4, the other end of the hinge pin 1 abuts against the pressing block 4, so that the position of the end cover 2 is limited by the hinge pin 1 and the outer cylinder 6, and the position of the pressing block 4 is limited by the hinge pin 1 and the large spring 3; after the pressing block 4 is pressed for a certain distance, the pin shaft 1 can move towards the central axis direction of the outer cylinder 6 under the action of the small spring 5 and is separated from the outer cylinder 6 and the end cover 2.
The compression elasticity of the large spring 3 is greater than the sum of the inertia force and the gravity of the pressing block 4 when the whole device touches water, but is less than the sum of the gravity of the device to be released 7 and the pressing block 4 in the water; the compression elasticity of the small spring 5 is larger than the friction force between the pin shaft 1 and the shaft holes of the end cover 2 and the outer cylinder 6. The device ensures that the whole device can be smoothly opened to release the equipment to be released 7 after contacting water.
And one end of the pin shaft 1, which is in contact with the pressing block 4, is spherical, so that the friction force is reduced conveniently.
The shaft hole II 2-1 of the end cover 2 is oblong in the direction of the central axis of the outer cylinder 6, so that impact force applied to the end cover 2 when entering water is prevented from acting on the pin shaft 1.
The pressing block 4 is a pressing block with two stepped notches 4-1, and the height of the upper end face of the pressing block 4 is higher than that of the position of the pin shaft 1, so that the pressing block 4 can be better pressed on the upper end face of the pressing block 4 to move downwards after the releasing device 7 is released.
When the releasing device 7 is not released, the spherical end of the pin shaft 1 is pressed on the pressing block 4 through the elasticity of the small spring 5, and the other end of the pin shaft sequentially penetrates through the shaft holes of the end cover 2 and the outer cylinder 6; one end of the large spring 3 is abutted 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 large 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 releasing device 7 is released, the releasing device 7 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 releasing device 7, after the pressing block moves for a certain distance, 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. The whole uncovering mechanism falls under the action of the self weight and the gravity of the device 7 to be released, and the uncovering action can be completed.
In summary, according to the underwater uncovering device disclosed by the invention, after the device 7 to be released is released, the uncovering device can smoothly uncover the device through a series of actions, the structural design is reasonable, the cost is low, the working process is stable, and the device 7 to be released cannot be damaged; the cover opening device does not need to consider the sealing problem, and the design and installation difficulty is reduced.
