Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As depicted in figs. 1 and 2, the manned submersible drop able ballast protective device of the present embodiment, comprise manned capsule 16, the manned bulkhead 8 of manned capsule 16 is welded with motor bearing seat 5, motor bearing seat 5 bending structure at a right angle, motor bearing seat 5 top is formed with erecting stage, be positioned at erecting stage underrun screw be connected with two go out shaft step motor 3, two go out the upper shaft of shaft step motor 3 through being connected with the inner hole of magnetic clutch 2 after erecting stage through hole, and located by radial holding screw, the top of magnetic clutch 2 is also provided with rotary handle 1 by flange, two go out shaft step motor 3 times shafts be connected with main shaft 9 by oldham coupling 4, main shaft 9 runs through manned bulkhead 8, run through position to be sealed by packing case 6, there is stay bearing plate 13 lower end of main shaft 9 by nut sleeve, also comprise drop able ballast 15, drop able ballast 15 falls to hang over the bottom of manned capsule 16 by cargo hook gear, and stay bearing plate 13 is in the below of drop able ballast 15, and the left end of stay bearing plate 13 fits in hull structure T profile 14, the bottom being positioned at manned bulkhead 8 has also been connected by screw sleeve mount pad 12, the bottom of sleeve mount pad 12 has two permeable holes, the bottom of sleeve mount pad 12 has been threaded connection level sensor 11, and manned bulkhead 8 has been threaded connection underwater electrical connector 10, be positioned on manned bulkhead 8 and be also provided with control box 7, the signal wire (SW) of level sensor 11 is connected with control box 7 by underwater electrical connector 10, two go out the buttock line of shaft step motor 3 and magnetic clutch 2 be connected to respectively on control box 7.
Stay bearing plate 13 one-tenth sector structure.
Stay bearing plate 13 can around main shaft 9 half-twist.
Drop able ballast 15 of the present invention is used to the droppable primary cutout or other ballasts that progressively increase positive buoyancy.
When manned submersible from the water surface gradually dive time, seawater enters into sleeve mount pad 12 by the permeable hole of two bottom sleeve mount pad 12, along with manned submersible progresses in seawater, the seawater entered in sleeve mount pad 12 gets more and more, after the seawater in sleeve mount pad 12 reaches the specific registration of level sensor 11, controller in control box 7 receives signal and to go forward side by side row relax, automatically the power supply of magnetic clutch 2 is connected afterwards, magnetic clutch 2 is in the state of closing, shaft step motor 3 clickwise 90 ° is gone out with Time Controller driving pair, and drive stay bearing plate 13 clickwise 90 ° by main shaft 9, now the throwing of drop able ballast 15 can be carried space to soar out, to facilitate abandoning in real time of drop able ballast 15.In order to ensure the reliability of this protective device, this protective device also has manual function, have shaft step motor 3 fault when two or do not receive control signal, now because magnetic clutch 2 is in the state of closing, by clickwise handle 1 to 90 ° of positions, stay bearing plate 13 can be rotated to vacant position.Easy to use and flexible, safe and reliable.
After manned submersible completes predetermined job task, need to be hung with water surface lifting appliance to carry out energy recharge and maintaining to the stand of surface mother ship, hang in the process of water outlet at manned submersible, seawater in sleeve mount pad 12 can be flowed out by two permeable holes of bottom, after the seawater in sleeve mount pad 12 flows to end, level sensor 11 transmits the signal to the controller in control box 7, and carry out signal transacting, automatically the power supply of magnetic clutch 2 is cut off afterwards, magnetic clutch 2 is in released state, shaft step motor 3 left-hand revolution 90 ° is gone out with Time Controller driving pair, and drive stay bearing plate 13 left-hand revolution 90 ° by main shaft 9, now can stay bearing plate 13 be put to drop able ballast 15, to facilitate the weight supporting drop able ballast 15, drop able ballast 15 case accident preventing maloperation from causing.In addition, in manned submersible maintaining process, because magnetic clutch 2 is in released state all the time, even if rotary handle 1 is by misoperation, can not by transmission of power on main shaft 9.
More than describing is explanation of the invention, and be not the restriction to invention, limited range of the present invention, see claim, within protection scope of the present invention, can do any type of amendment.
