Description
Technical field
This utility model is related to a kind of underwater ejectioning technology, specifically realizes throwing automatically the one kind for carrying for deep sea sampler
Mechanism.
Background technology
As country is carried forward vigorously to Yu Haiyang development strategy, substantial amounts of underwater installation technology is able to fast development, with
When in order to reduce the danger that the mankind work under water, increasing equipment is intended to automatization.In order to realize deep sea sampler
Automatic floating after sampling, when the depth of dive reaches device predetermined value, triggers load rejection mechanism so that sampler is top-uped
Power, is emerged safely.At present the floating of deep sea sampler is main is connected to the hawser on sampler by winch dragging, and water
Lower equipment throwing load mode has several as follows：
Electromagnetic type is thrown and is carried：Triggered by electric magnet, a kind of throwing load mode combined with frame for movement.When electric magnet dead electricity
When, weight throwing load is completed by releasing the constraint of frame for movement.This device because when load is not thrown electric magnet always electric, scarce
Point is that power consumption is larger, and relatively costly, action is unstable.
Blasting bolt formula is thrown and is carried：Make shearing lock cut off or weaken groove along bolt using blasting bolt to disconnect, realize weight
Separate with body.Although this device large carrying capacity, is because generally requiring multiple bolts, it is ensured that whole bolts are simultaneously
Disconnect difficulty greatly, and as explosive forces are big, need to arrange protection structure, relatively costly.
Fuse Type is thrown and is carried：With single-chip microcomputer as control core, by a series of circuits fuse alloy resistance wire, so as to disconnect with
The connection of ballast weight.This device needs to receive outside throwing load instruction, and signal easily receives external interference, circuit under abyssal environment
Design more complicated, high cost.
In order to further meet the stability requirement of underwater installation load rejection mechanism, power consumption requirements, cost requirement, automatization will
Ask, need further to research and develop new underwater ejection device.
Content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, this utility model throws carrier aircraft automatically there is provided a kind of deep sea sampler
Structure, its carry out throwing load, idle, simple structure having stable behavior automatically by the use of seawater pressure as trigger.
The technical scheme adopted by this utility model is：
This utility model includes piston, outer tube, screw, kentledge, steel ball and spring, steel ball, cover, piston spring and interior
Cylinder, the piston are connected by gap with outer tube, one week uniform endoporus of the kentledge, and inner core barrel uniformly leads to for one week
Hole, kentledge endoporus are coaxial with inner core barrel through hole, and described outer tube one end is opening, and outer tube is connected by screw with inner core, cylinder
Lid is closely connected with inner core；The elastic force side that steel ball is obtained by spring precommpression pushes against piston, and opposite side pushes against steel ball and spring,
The elastic force side that steel ball and spring is obtained by itself precommpression pushes against steel ball, and opposite side pushes against kentledge, top one week on piston
Uniform through hole, mid portion are provided with annular groove, and end is halfpace face, and piston spring original state is compressive state, side and piston
The halfpace face of end pushes against, and opposite side is pushed against with cover.
Furtherly, the length of described annular groove bigger than the diameter of steel ball 1/2nd, the depth of annular groove are slightly larger than steel ball
Diameter.
Furtherly, groove, groove o types sealing ring installed above are provided with described inner core.
On piston, through hole is easy to sea water to pass through, and plays pressure compensation effect to outer tube cavity volume, while the both sides shape in piston
Into the motion that pressure differential promotes piston, piston movement enters the ring of piston in the presence of pretensioned spring to certain position steel ball
At groove, as the constraint without steel ball is so as to be released, piston forms an adjustable resistance mechanism with piston spring to kentledge,
Certain seawater pressure is balanced, and depth is carried such that it is able to regulate and control to throw.
Compared with prior art, the beneficial effects of the utility model are：
1st, the motion of piston is based on differential hydro cylinder principle, and then controls the release of kentledge, whole supplies without the need for the energy
Give.
2nd, piston and piston spring form an adjustable resistance mechanism, balance certain seawater pressure, such that it is able to from homophony
Control is thrown and carries depth.
3rd, part is frame for movement, and environment resistant interference performance is strong, good stability.
4th, each component structural is simple, easy to process.
