Abstract
The utility model relates to a manual ballast discarding device. The manual ballast discarding device is characterized in that a drive mechanism, a discarding mechanism and a pressing iron are included, wherein the drive mechanism is connected with a plug-pull pin through a wire rope. When the pressing iron is discarded, the drive mechanism can pull the plug-pull pin through the wire rope to release the pressing iron from the restriction of a rotary hanging rod. The manual ballast discarding device has the advantages of high reliability and simple operation, and can manually discard the ballast quickly under emergency in the absence of a hydraulic power source or a power supply, so that a submersible vehicle can quickly float to reduce the hidden danger and the loss of life and property and achieve stronger emergency response capability. The ballast discarding operation includes the steps of rotating a hand wheel anticlockwise and then rotating the hand wheel clockwise to generate the drive force for discarding the ballast, thereby eliminating the hidden danger caused by mis-operation of personnel.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, 2, 3, the utility model comprises driver train 200, abandons mechanism 100 and foundary weight 29, abandons the bottom that mechanism 100 and foundary weight 29 are installed in submersible 400, and driver train 200 is installed on the pressure shell of pressure-resistant cabin 300.Abandon mechanism 100 and comprise rotation peg 33, rotating peg 33 articulates by bearing pin 32 and adapter plate 27, bearing pin 32 is fixed on the adapter plate 27 by fix screw 31, rotating peg 33 can rotate in the groove on the adapter plate 27 35, the front end that rotates peg 33 is provided with hangs groove 28, hang groove 28 and be open slot, foundary weight 29 is fixedly mounted on by captive nut 40 and hangs on the bar 41, and foundary weight 29 is hung hanging in the groove 28 at rotation peg 33 front ends by the screw head of hanging on the bar 41 30 of hanging.Insert-pull pin 34 slides in first otic placode 36 and second otic placode 37, first otic placode 36 and second otic placode 37 are welded on the adapter plate 27, insert-pull pin 34 is pushed down the rear end of rotating peg 33, be provided with third ear plate 42 behind second otic placode 37, stage clip 38 is enclosed within insert-pull pin 34 rear portions, one end of stage clip 38 props up third ear plate 42, and the other end of stage clip 38 axially compresses insert-pull pin 34, makes insert-pull pin 34 keep pushing down the state that rotates peg 33 rear ends.Since foundary weight 29 rotate hanging point on the peg 33 from the distance of bearing pin 32 less than the distance of insert-pull pin 34 with bearing pin 32, according to lever principle, the thrust of insert-pull pin 34 is much smaller than the weight of foundary weight 29.Driver train 200 connects insert-pull pin 34 by wirerope 1, and the tail end of wirerope 1 passes third ear plate 42, and the tail end with insert-pull pin 34 in stage clip 38 links to each other, and stage clip 38 can not extracted insert-pull pin 34 because of the shake of submersible, can not produce unexpected the throwing and carry.Be provided with hard sheath 2 outside the wirerope 1, hard sheath 2 is captiveed joint with third ear plate 42.
When needs are abandoned foundary weight 29, when operating driver train 200, the operator spurs insert-pull pin 34 by wirerope 1, and wirerope 1 overcomes the elastic force of stage clip 38, and insert-pull pin 34 is extracted.After insert-pull pin 34 was pulled out, foundary weight 29 by gravitys pulling rotation peg 33 rotated around bearing pin 32, made and rotated peg 33 upsets, hung hang groove 28 slippage of bar 41 from rotation peg 33, thereby made foundary weight 29 abandon.Before foundary weight 29 was not abandoned, stage clip 38 compressed insert-pull pin 34, made that hanging bar 41 hangs on the rotation peg 33 safely.
As shown in Figure 4, driver train 200 comprises the outer sleeve 6 that is welded on pressure-resistant cabin 300 housings 8, be provided with first negative thread 19, second negative thread 20 and the 3rd negative thread 24 in the outer sleeve 6, first negative thread 19 is arranged on the inner of outer sleeve 6, the 3rd negative thread 24 is arranged on the outer end of outer sleeve 6, first negative thread 19 and the 3rd negative thread 24 are minus thread, second negative thread, 20 right-hand screw threads.Baffle plate 4 is fixedly mounted on the outer end of outer sleeve 6 by screw 5.
The outer end of outer shaft 23 is provided with cable rolling wheel 26, wirerope 1 is wound in the volume groove 2601 of cable rolling wheel 26, outer shaft 23 rotatable being installed in the outer sleeve 6, minus thread engagement between the 3rd negative thread 24 of outside thread 25 on the outer shaft 23 and outer sleeve, be provided with seal ring 7 between outer shaft 23 and the outer sleeve 6, it is minus thread that the inner of outer shaft 23 is provided with the 4th negative thread 22, the four negative threads 22.
Interior rotating shaft 14 rotatable being installed in inner sleeve 9 and the outer sleeve 6, interior rotating shaft 14 is provided with first outside thread 15, second outside thread 18 and the 3rd outside thread 21, the first outside threads 15 and the 3rd outside thread 21 is a minus thread, and second outside thread 18 is a right-hand screw thread.9 of interior rotating shaft 14 and inner sleeves are provided with lip-type packing 10, block nut 11 is by being threaded into the terminal of inner sleeve 9 and compressing lip-type packing 10, lip-type packing 10 forms rotary seal between interior rotating shaft 14 and inner sleeve 9, even can guarantee to be provided with between outer shaft 23 and the outer sleeve 6 under the situation of seal ring 7 inefficacies, seawater can not enter pressure shell inside, simultaneously, interior rotating shaft 14 is sleeved in the block nut 11, and rotating shaft 14 can off-axis in rotation process in can also guaranteeing.The outer end of interior rotating shaft 14 is installed with handwheel 12 by nut 13.
The outside of wirerope 1 is with hard sheath 2, (other end of hard sheath 2 is fixed on the third ear plate 42) that the termination of hard sheath 2 and fixed support 3 are fixed together.Wirerope 1 is passed in hard sheath 2 and fixed support 3, and can freely twitch and be not subjected to the restriction in path.The effect of hard sheath 2 is that wirerope 1 is when tension, under the effect of hard sheath 2, can not be out of shape, therefore, the mechanism 100 that abandons of the present utility model can be according to the design needs of submersible, are installed separately the different parts of submersible with driver train 200 and are connected by wirerope 1.
During initial condition, second outside thread 18 of interior rotating shaft 14 and second negative thread engagement 20 of outer sleeve 6; When abandoning the ballast operation, at first rotate counterclockwise handwheel 12, rotating shaft 14 is mobile to out of my cabin by the engagement between second negative thread 20 of second outside thread 18 in the interior rotating shaft 14 and outer sleeve 6 in making, after second negative thread 20 of second outside thread 18 in the interior rotating shaft 14 and outer sleeve 6 broke away from, rotation handwheel 12 continues to rotate counterclockwise can not make interior rotating shaft 14 continue to out of my cabin mobile; Should change into and clockwise rotate handwheel 12 this moment, and first outside thread 15 of interior rotating shaft 14 enters engagement with the 5th negative thread 16 in the inner sleeve, and interior rotating shaft 14 continues outside cabin and moves; Continue to clockwise rotate handwheel 12, the 3rd outside thread 21 of interior rotating shaft 14 also enters engagement with the 4th negative thread 22 on the outer shaft 23, after the 3rd outside thread 21 of interior rotating shaft 14 and the 4th negative thread 22 on the outer shaft 23 mesh fully, 26 rolling wireropes 1 are taken turns in the cable rolling that drives outer shaft 23 rotations and drive on the outer shaft 23, finally extract insert-pull pin 34 and abandon foundary weight 29.Baffle plate 4 can guarantee that outer shaft 23 can not screw out outer sleeve 6 in rotation process.Can see by said process, need derotation handwheel 12 after, dextrorotation handwheel 12 just can produce and throw carry a propulsive effort again, has eliminated the potential safety hazard that personnel's maloperation brings.
