After the navigation is over, it needs to provide buoyancy, and after surfacing, it is salvaged and recovered to complete the playback of test data. The recovery of most underwater vehicles is mainly carried out by displacement. There are only 4 groups of displacement structures in existing products. The displacement state is in the vertical direction and the displacement is simultaneous. The shear force carried by the explosive bolts is small, the positive buoyancy provided is small, and the displacement is carried out in shallow water areas. This underwater vehicle is in a horizontal posture in the water and weighs 2 tons. It needs to provide a large positive buoyancy and complete large mass displacement at a large depth underwater to generate sufficient positive buoyancy. The original displacement structure needs to be improved. This solution is proposed to address this problem. Summary of the invention

[0035] The spring 3 is sleeved on the upper end of the flange of the impact-type separation bolt 4 to increase the thrust during load release.
[0036] The O-shaped sealing ring 5 is sleeved in the lower end groove of the punch-type separation bolt 4.
[0037] The screws 9 and the spring washers 8 are used to cooperate with the punch-type separation bolts 4 to fix the load block 2 on the housing 1 through the mounting holes 11 .
[0038] The load block 2 is connected to the housing 1 via a spring 3 to ensure that the load block leaves the aircraft quickly.
[0039] The sealed load discharge structure sends out load discharge signals in a timed sequence through an electronic device to complete the load discharge function in a timed sequence.
[0040] In some embodiments, the impact-type separation bolt 4 adopts a separation-impact type working mode.
[0041] In some embodiments, the through groove design at the bottom of the load-discharging block 2 facilitates the inflow of seawater to balance the external pressure and reduce the resistance during load discharging.
[0042] In some embodiments, the O-ring 5 is installed in the lower end groove of the breakaway separation bolt 4, which is then installed on the housing 1, and the flat gasket 6 is installed and tightened with screws 9 and spring flat washers 8.
[0043] In some embodiments, when in use, the electronic component provides a timing signal to detonate the shear-type separation bolts 4 of each group of sealed load-discharging structures in sequence, and the load-discharging block 2 is quickly discharged and away from the underwater vehicle under the action of the elastic force of the spring 3, the explosive impact force of the shear-type separation bolts 4 and the inertial force.
[0044] In some embodiments, the number of the sealing row support structures is 8 groups.
[0045] In some embodiments, an underwater vehicle is provided with a multi-group time-sequential loading structure that is sealed at a large underwater depth. After the loading is completed, the underwater vehicle floats up, completes salvage and recovery, and performs data playback.
[0046] An embodiment of the present invention provides an underwater vehicle provided with a large-depth multi-group sealed load-carrying structure of the underwater vehicle of any of the above embodiments.
[0047] In the above embodiment of the present invention, when in use, multiple sets of sealed load-discharging structures with a large depth are assembled on the cabin shell of the underwater vehicle. After the voyage is completed, the electronic component provides a timing signal to detonate 8 sets of impact-type separation bolts in sequence. The load-discharging blocks are quickly discharged and away from the underwater vehicle under the action of spring force, impact force of the impact-type separation bolts and inertial force. After the underwater vehicle completes the load-discharging, it floats up, completes the salvage and recovery, and performs data playback.
[0048] In order to achieve reliable load removal with multiple groups at large depths and meet sealing requirements, the device consists of a shell and 8 groups of sealed load removal structures, see Figure 1, because the number of explosive bolts used for unloading is large, the impact force of unloading on electronic components is too large at the same time, and the underwater vehicle is in a horizontal posture in the water, so there is no need to unload at the same time. An electronic device is used to send out unloading signals in sequence to complete the unloading function in sequence, avoiding the strong impact caused by unloading 8 groups of unloading structures at the same time; each group of sealing unloading structures is mainly composed of break-off separation bolts, unloading blocks, springs, O-rings, screws, nuts and spring washers, etc. Figure 2 ; In order to complete the deep-sea load discharge, the breaking type separation bolt is selected, which provides a large impact force when breaking, discharges the load block, and meets the requirements of large shear force. At the same time, a spring is added between the load block and the shell to increase the thrust during load discharge and ensure that the load block leaves the vehicle quickly; in order to reduce the difficulties caused by the high pressure in the deep sea and reduce the contact area between the load block and the shell, the bottom of the load block is designed as a through groove, see Figure 3 , it is convenient for seawater to flow in to balance the external pressure and reduce the resistance during loading. The installation hole is located in the middle position, which is convenient for the horizontal vehicle to complete loading.
[0049] Put the O-ring into the lower end groove of the break-off type separation bolt, then install it on the shell of the underwater vehicle's load-discharging section, install the flat washer, tighten it with a nut, put the spring on the upper end of the break-off type separation bolt flange, place the load-discharging block on the upper end of the spring and the break-off type separation bolt, and tighten it with screws and spring flat washers; the break-off type separation bolt adopts the separation break-off type working mode, which can withstand greater tensile and shear forces.
