Description

Technical Field

[0001] This invention pertains to underwater icebreaking technology for missiles, specifically a high-pressure water jet combined with mechanical blades for icebreaking that assists in underwater missile launch. Background Technology

[0002] The polar seas are covered with ice sheets and large icebergs, which pose a serious threat to the safety of submarines. Submarines surfacing to launch missiles by breaking through ice sheets or large icebergs would make navigation and operation more difficult, damage the submarine's structure, increase the risks of missile launches, and slow down post-operation withdrawal.

[0003] Furthermore, during the underwater missile launch process of a submarine, the presence of ice layers causes enormous friction and resistance as the missile passes through the ice, significantly reducing its initial launch velocity and kinetic energy, thus lowering the launch success rate and seriously threatening the submarine's own safety when launching missiles.

[0004] With the continuous advancement of military technology and the ongoing international arms race, developing more advanced missile systems has become an integral part of a nation's military strength. Auxiliary missile ice-breaking devices represent an advancement in missile launch technology, contributing to improved missile system adaptability and reliability, enabling them to function in a wider range of environments.

The power unit drives the generation of rotary cutting force and high-pressure water jets to cut and break ice layers. The power unit internally includes a drive system, a water jet system, a dynamic sealing system, and a hydraulic support system. The drive system drives the rotary ice-breaking mechanism to rotate. The water jet system generates high-pressure water flow, causing the rotary ice-breaking mechanism to spray high-pressure water jets to cut the ice layer.

[0034] The output port of the multi-in-one connector is located on the stator part at the bottom of the dynamic sealing device and remains fixed to the input water pipe;

[0035] The rotor portion of the dynamic sealing device is located below the high-pressure diversion tank at the bottom center of the cutting disc, and rotates together with the rotary ice-crushing mechanism.

[0036] The output water pipe I connects the outlet of the high-pressure diversion tank and the installation inlet of the diversion device;

[0038] The output water pipe is used to connect the outlet of the distributor and the water jet nozzle.

[0039] The hydraulic support system includes a main hydraulic cylinder, a secondary hydraulic cylinder, a support bracket, and a slewing bearing.

[0040] The main hydraulic cylinder and the secondary hydraulic cylinder are located between the rotary ice-cutting mechanism and the rotary bearing. Their upper and lower ends are fixed by support brackets. The axis of the main hydraulic cylinder is at a certain angle to the center line of the power compartment, and the whole is arranged in a triangular shape to support the weight of the entire rotary ice-cutting mechanism. The axis of the secondary hydraulic cylinder is at a certain angle to the circumferential tangent of the power compartment to resist the tangential force generated when the rotary ice-cutting mechanism rotates.

[0041] The hydraulic support system is equipped with a sensor control system, including a hydraulic pump, oil tank, three-position four-way solenoid valve, operational amplifier, hydraulic cylinder group, motor, feedback potentiometer, and command meter.

[0042] The stroke end of the hydraulic cylinder assembly is connected to the bottom of the rotary ice-chopping mechanism, and its oil inlet and outlet are connected to a three-position four-way solenoid valve.

[0043] The three-position four-way solenoid valve is connected to the hydraulic pump, its pressure relief port is connected to the oil tank, and its signal terminal is connected to the operational amplifier to transmit the hydraulic cylinder group oil pressure signal.

[0044] The operational amplifier output is connected to a feedback potentiometer, which is used to adjust the feedback resistor and input voltage, thereby achieving linear amplification of the signal and bringing its gain to the expected level.

[0045] The feedback potentiometer is connected to the command potentiometer and is used to provide feedback on the oil pressure status of the sensing system and to send control commands to the motor.

[0046] The motor is connected to drive the rotary ice-cutting mechanism and outputs the working speed according to the control command, thereby controlling the working state of the rotary ice-cutting mechanism.

[0047] The hydraulic support system is also equipped with a sensor control method, including the following steps:

[0048] Step 1: The sensor control process is initiated, and the oil pressure status of the hydraulic system is monitored.

[0049] Step 2: The control unit processes the received oil pressure data;

[0050] Step 3: The system determines whether it is in the optimal working state and whether it has reached the oil pressure for ice breaking;

[0051] Step 4: When the rotary ice-cutter touches the ice surface, the oil pressure rises to the ice-breaking oil pressure standard, the motor starts working, and the rotary ice-cutter begins the ice-breaking operation.

[0052] Step 5: By detecting the oil pressure status of the hydraulic cylinder, the controller controls the power of the hydraulic pump to adjust the propulsion stroke of the hydraulic cylinder group, so as to control the cutting posture of the rotary ice-crushing mechanism;

[0053] Step 6: When the ice breaking is complete, the controller disconnects the power and the motor stops working.

[0054] A method for operating a high-pressure water jet combined with a mechanical blade ice-breaking device for assisting underwater missile launch includes the following steps:

[0055] Step 1: The missile propels upward from underwater, causing the rotating ice-cutting mechanism to gradually contact the bottom of the ice layer;

[0056] Step 2: When the rotary ice-cutting mechanism contacts the ice surface, due to the obstruction of the ice layer and the propulsion force of the missile, the hydraulic support system detects an increase in the oil pressure of the main hydraulic cylinder supporting the rotary ice-cutting mechanism. The controller then starts the motor to drive the rotary ice-cutting mechanism to rotate and begin cutting the ice layer for ice-breaking operations. At the same time, the sensor control system detects the cutting status of the rotary ice-cutting mechanism, adjusts the support angle and working oil pressure of the secondary hydraulic cylinder, and optimizes the output power of the motor.

[0057] Step 3: After the device completes ice breaking, the entire device floats out of the ice surface. The hydraulic support system detects that the oil pressure of the main hydraulic cylinder has decreased, the controller disconnects the power supply to the motor, the rotary cutting ice-breaking mechanism stops rotating, and the separation device is activated, causing the entire ice-breaking device to detach obliquely from the projectile.

[0058] The beneficial effects of the present invention are as follows: Compared with the prior art, the high-pressure water jet combined with mechanical blade ice-breaking device for assisting underwater missile launch provided by the present invention can assist underwater missiles in quickly breaking through ice and emerging from the water, reduce the risk of underwater vehicles launching missiles in icy waters, increase the speed of withdrawal after combat, and help improve the adaptability and reliability of the missile system, enabling it to play a strike and deterrent role in a wider range of environments.
