[0036] In a more specific application scenario, when the submarine encounters a special situation and needs to be thrown, the one-way electromagnetic valve 502 is opened, seawater is filled into the throw frame 1, the hydraulic cylinder one 506 drives the sealing extrusion plate 507 to extrude the water body, the water body is guided to the inner side wall of the throw frame 1 under the action of the conical flow guide column 515, and the fitting plate 510 extrudes the upper plate 511 during installation, so that the compression spring rod 516 is in the maximum compression degree, and the telescopic limiting rod 517 limits the compression degree to prevent the compression spring rod 516 from being compressed to lose the elastic performance. The extrusion of the water body and the reaction force of the compression spring rod 516 push the fitting plate 510, when the pressure received by the fitting plate 510 reaches a certain value, the curved pull-off rod 521 is pulled off, then the curved surface plate 505 is passively deflected outward, the L-shaped butt joint block 512 loses the limitation of the curved surface plate 505, at this moment, the fitting plate 510 is passively pushed out of the throw frame 1, and the fitting plate 510 has a large impact energy, which makes the submarine have an upward impact kinetic energy after one throw, accelerates the upward movement of the submarine, and thus improves the use value of the throw device.

[0037] It should be noted that at the moment when the curved pull-off rod 521 is broken by the pushing force, the extrusion force of the water body and the reaction force of the compression spring rod 516 drive the fitting plate 510 to be pushed out of the inside of the throw frame 1 at once. The submarine in this state has the maximum pushing kinetic energy, and as the submarine floats up, its kinetic energy gradually decreases.

[0038] Specifically, the cross section of the sealing extrusion plate 507 is concave-convex, and the position where it contacts the inner side wall of the throw frame 1 is convex. When the hydraulic cylinder one 506 drives the sealing extrusion plate 507 to extrude the water body, the pushing force at the convex position is the largest, and the pushing force exerted on the curved pull-off rod 521 is the strongest, thereby avoiding the situation that the curved pull-off rod 521 cannot be pulled off, and ensuring that the submarine can be smoothly thrown.

[0039] Reference Figure 1 , Figure 2 , Figure 6 and Figure 7In a preferred implementation, the top of the fitting pressboard 510 is fixedly connected with a disengaging frame two 4, and the disengaging frame two 4 is provided with a secondary ejection assembly 8, which includes a supporting ring plate 801 and a mounting outer plate 802. The supporting ring plate 801 is fixedly connected to the outer side of the disengaging frame two 4. The outer side of the disengaging frame two 4 above the supporting ring plate 801 is annularly distributed with hydraulic cylinders four 809, and the output end of each hydraulic cylinder four 809 is fixedly connected with an adjusting plate 806. The side of the adjusting plate 806 facing the outer side of the disengaging frame two 4 is fixedly connected with a clamping plate 805 at equal distances. The outer side of the mounting outer plate 802 is annularly distributed with a butt joint plate 804. The number of butt joint plates 804 is the same as that of the adjusting frames. The outer side of the butt joint plate 804 is equally spaced apart to form a clamping groove 810. The clamping plate 805 and the clamping groove 810 are matched. The bottom inner wall of the disengaging frame two 4 is fixedly connected with a plastic frame 807. The top of the plastic frame 807 is fixedly connected with a flow guide ring-shaped circular rod 811. The outer side of the plastic frame 807 is equally spaced apart to form an anti-friction arc rod 808. The bottom of the mounting outer plate 802 is provided with a suspension air bag 803, which is located in the space between the disengaging frame two 4 and the plastic frame 807.

[0040] Specifically, after the first ejection is completed, the underwater vehicle obtains an upward power propulsion. When it propels for a period of time, the kinetic energy is gradually weakened. Then the clamping plate 805 on the adjusting frame is disengaged from the clamping groove 810 of the butt joint plate 804 under the action of the adjusting hydraulic cylinder four 809. The mounting outer plate 802 is in an unrestricted state. The suspension air bag 803 below the mounting outer plate 802 gradually disengages from the plastic frame 807 and the disengaging frame two 4. The suspension air bag 803 gradually expands, thereby providing an upward buoyancy to the underwater vehicle. The secondary ejection assembly 8 provides a secondary upward propulsion to the underwater vehicle after the first ejection, thereby accelerating the upward movement of the underwater vehicle and further improving the use value of the ejection assembly.

[0042] It should be noted that, on the basis of the work of the second-time throwing load assembly 8, the adjusting hydraulic cylinder three 705 drives the deflection hanging rod 701 to move away from the disengaging frame 3, so that the deflection hanging rod 701 drives the rotating rod 706 to rotate, and when the deflection hanging rod 701 is separated from the mounting groove 702, the counterweights 704 are gradually separated from the deflection hanging rod 701, so that the separation of the counterweights 704 reduces the resistance of the submarine to float to the water surface, and after the third-time throwing, the submarine can quickly float to the water surface, so as to ensure that the throwing device can realize the highest efficiency of floating when the submarine is in emergency throwing, and the use value of the throwing device is ensured.

10. A method for deploying a marine hydrological detection instrument, using a marine hydrological detection instrument deployment device as described in claim 9, characterized in that, The delivery method includes the following steps: Step 1: When the submersible encounters a special situation and needs to jettison, the one-way solenoid valve (502) is opened, and seawater is poured into the jettison frame (1). The hydraulic cylinder (506) is adjusted to drive the sealing extrusion plate (507) to extrude water. The extrusion of water, combined with the reaction force of the compression spring rod (516), pushes the bonding plate (510). When the pressure on the bonding plate (510) reaches a certain value, the bending break rod (521) is broken, and the curved plate (505) is passively deflected to the outside. The L-shaped docking block (512) loses the constraint of the curved plate (505). At this moment, the bonding plate (510) is passively pushed out of the jettison frame (1). Step 2: After a ballast jettison is completed, the submersible gains an upward thrust. After a period of thrust, the hydraulic cylinder 4 (809) drives the clamping plate (805) on the adjustment frame to disengage from the slot (810) at the docking plate (804). The mounting plate (802) is then in an unrestricted state. The suspension airbag (803) below the mounting plate (802) gradually disengages from the molding frame (807) and the disengagement frame 2 (4). The suspension airbag (803) gradually unfolds, thereby providing an upward buoyancy to the submersible. Step 3: Based on the operation of the secondary load-release assembly (8), adjust the hydraulic cylinder three (705) to drive the deflection rod (701) to move away from the release frame one (3). Then the deflection rod (701) drives the rotating rod (706) to rotate. When the deflection rod (701) separates from the mounting slot (702), the counterweight (704) gradually separates from the deflection rod (701), realizing the separation of the load and further reducing the resistance of the submersible to rise.
