Embodiment
A kind of course of work of underwater emergency jettison system provided by the utility model is as follows：
1. the preparation before carry：
(1) load-bearing lever 16 is by the effect of resetting spring 14, and at an angle with vertical direction, which can be by limiting
Bar 12 is adjusted.
(2) carry oil cylinder 10 and throwing carry 11 piston rod of oil cylinder and are only acted on by internal reset spring, stroke zero.
(3) carry oil cylinder 10 is connect with oil inlet pipe.
(4) electromagnet 1 does not power on, is not attracted with iron 2 is inhaled, 6 push the spring bottom plate 7 of compressed spring and driving lever 23, forward
It moves 9 side of side plate so that driving lever 23 and back side panel 8 be not at an angle, parallel.
2. the process of carry：
(1) ballast 20 passes through the opening on bottom plate 19 together with hyoplastron 18, gradually moves up.
(2) on hyoplastron 18 protrusion first with end in contact before load-bearing lever 16, due to 16 front end of load-bearing lever be external arc,
So load-bearing lever 16 can follow the protrusion on hyoplastron 18 to move together.
(3) since driving lever 23 is not parallel with back side panel 8, the movement for load-bearing lever 16 provides space, until load-bearing
Lever 16 is horizontal substantially.There are many determination method that load-bearing lever 16 is horizontal, including setting flag bit or limit
Block etc..
(4) it is that electromagnet 1 powers on.
(5) hydraulic power source of BootLoader oil cylinder 10, under the action of hydraulic coupling, the planar end surface of piston rod pushing drawing rod 3, together
When, it is close to electromagnet 1 therewith to inhale iron 2.
(6) driving lever 23 gradually restores the parastate with back side panel 8, state as shown in Figure 1 under the drive of pull rod 3.
(7) 17 end of load-bearing lever is located between 23 front opening of driving lever, and driving lever 23 limits the rotation of load-bearing lever 17
Trend.
(8) electromagnet 1 with inhale after iron 2 contacts, under the action of electromagnetic force, the two is closely attracted, this adsorption capacity be enough to
The spring force of incompressible spring 6.
(9) hydraulic power source of carry oil cylinder 10 is closed, under internal action of reset spring, piston rod is gradually retracted into zero stroke
Position.
(10) hydraulic power source of removal carry oil cylinder 10 completes carry.
3. throwing action relationships when carrying：
A kind of underwater emergency jettison system provided by the utility model there are two types of throw carry executive mode, i.e., power-off throw carry and
Hydraulic cylinder is actively thrown and is carried, and illustrates separately below：
(1) power-off, which is thrown, carries：(a) it either actively powers off, or is powered off because of electrical malfunction, the absorption of electromagnet 1
Power disappears, and 23 end of push the spring bottom plate 7 and driving lever immediately of compressed spring 6 is moved to 9 side of front side board.(b) when driving lever 23
When front end is detached with 16 end of load-bearing lever completely, load-bearing lever 16 tilts immediately under the action of ballast 20, to jettisoning
Ballast 20 is completed to throw load.
(2) hydraulic cylinder is actively thrown and is carried：(a) piston rod for carrying oil cylinder 11 is thrown under the promotion of hydraulic coupling, gradually to driving lever 23
Front end is close.(b) 23 front end of piston rod promotion driving lever for carrying oil cylinder 11 is thrown, it is made to be gradually disengaged with 16 end of load-bearing lever.(c)
To avoid the case where electromagnet still powers at this time from occurring, hydraulic coupling (according to lever principle, scaling up) should be greater than electromagnetism
The sum of frictional force between 1 adsorption capacity of iron and load-bearing lever 16 and driving lever 23.(d) when 23 front end of driving lever completely with the end of load-bearing lever 16
When the separation of end, load-bearing lever 16 tilts immediately under the action of ballast 20, to jettisoning ballast 20, completes throwing and carries.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Any modification, equivalent replacement and improvement etc., should be included in this reality made by within the spirit and spirit of utility model
Within novel protection domain.
