Description

Technical Field

[0001] The present invention belongs to the field of submarine surfacing, icebreaking and water exit in polar regions, and in particular relates to a submarine surfacing auxiliary icebreaking device based on electromagnetic resonance and an icebreaking method thereof. Background Art

[0002] In recent years, with the continuous innovation and development of science and technology, the problem of resource shortage cannot be ignored. In an era when energy and natural resources are so scarce, finding a resource-rich "paradise" that can be mined is an urgent matter. In today's international environment, the rich natural resources and unique ecological environment of the polar regions have attracted widespread attention from the world. However, the temperature in the polar regions is extremely low and the wind speed is extremely high, which has brought great difficulties to exploration and mining. At the same time, global climate change has a particularly significant impact on the poles, resulting in accelerated melting of ice sheets, rising sea levels, and changes in ecosystems. These changes not only affect biodiversity, but also pose new challenges to the feasibility assessment of resource development. Therefore, how to correctly detect and evaluate the polar environment has become a top priority for polar resource exploitation, and polar submarines play an important role in this. First of all, polar submarines can perform missions in ice-covered waters. This gives them a unique advantage in polar exploration. Secondly, the special design and functions of polar submarines enable them to perform well in extreme environments. They usually have a reinforced hull and power system, and can break ice and surface under thick ice. This ability is crucial in polar exploration. However, because the polar regions are covered with ice and snow all year round, how to break ice safely and efficiently has become the key to the successful completion of the mission of submarines. Therefore, research on submarine surfacing and icebreaking is particularly important. Under normal circumstances, the most commonly used means of submarine surfacing and breaking ice are direct squeezing of ice by submarines and blasting of ice by missiles. Taking a polar unmanned underwater icebreaking navigation system with application number CN202011349921.0 as an example, this method of first using high-energy explosives and then surfacing to break ice requires high structural strength of the submarine, and causes greater damage to the submarine hull, as well as huge consumption of resources and energy. Summary of the Invention

[0003] In view of this, the present invention aims to propose a submarine surfacing auxiliary icebreaking device based on electromagnetic resonance and an icebreaking method thereof, so as to solve the problem that the existing icebreaking means first uses high-energy explosives and then surfaces to break the ice, which has high requirements on the structural strength of the submarine, causes great damage to the submarine shell, and consumes huge resources and energy.

[0004] To achieve the above object, the present invention adopts the following technical solutions: A submarine surfacing auxiliary icebreaking device based on electromagnetic resonance includes a mounting platform, a resonance system and a hook. The mounting platform is arranged on the submarine hull, the top of the resonance system is connected to the hook, and the resonance system is installed in the mounting platform.

[0005] Furthermore, the resonance system includes a magnetic end, a spring and a magnetic part, the spring is installed between the magnetic end and the magnetic part, the magnetic end and the magnetic part are installed at the lower end and the upper end of the mounting platform respectively, and the magnetic part is connected to the hook.

[0006] Furthermore, an electric wire is wound around the magnetic member, and the end of the electric wire is installed in the submarine hull.

[0007] Furthermore, when no power is supplied, the magnetic end and the magnetic member are attracted to each other, and when power is supplied, the magnetic end and the magnetic member are repelled to each other.

[0008] Furthermore, the end of each claw of the hook is connected to a motor, and a hole is provided at the connection between the magnetic member and each claw of the hook.

[0009] Furthermore, the installation platform is a frustum-shaped double-layer shell.

[0010] An icebreaking method for a submarine surfacing auxiliary icebreaking device based on electromagnetic resonance, comprising the following steps: Step 1: Adjust the distance and angle between the hook and the ice layer through motor control; Step 2: After the submarine reaches the estimated position, it leaves a certain distance for surfacing; Step 3: The submarine then ascends, and while ascending, the magnetic element is quickly energized. At this time, the magnetic element and the magnetic end repel each other. Under the combined action of the spring force, the magnetic force, and the momentum provided by the submarine's own surfacing, the claw is quickly launched upward and shot into the ice layer; Step 4: Under the control of the motor, the tip of the claw retracts and grabs the ice; Step 5: Continuously change the power state of the magnetic component to change its polarity. Combined with the elastic force of the spring, the hook is made to vibrate up and down within a certain amplitude range, thereby driving the ice layer to resonate. The vibration eventually causes the ice layer to break, enabling the submarine to surface, break the ice and exit the water.

[0011] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can utilize the principle of resonance energy concentration to achieve maximum destructive effect with relatively small energy, and help submarines quickly break ice and exit the water in a safe and stable manner.

[0012] 2. The present invention utilizes resonance to replace direct collision and extrusion icebreaking and missile blasting icebreaking, which not only reduces the local damage caused by local extrusion on the submarine, but also reduces the danger of the submarine breaking ice.

[0013] 3. The present invention creates a resonance environment through the combined action of electromagnetism and springs, which reduces energy consumption to a certain extent.

[0014] 4. The present invention uses resonance to break ice, so that the frequency of the forced vibration of the ice is close to the natural frequency of the ice. By using the principle of resonance energy concentration, local energy accumulation of the ice is achieved through relatively small energy consumption, and finally the energy is released to destroy the ice. Under limited energy consumption, the efficiency of ice breaking is greatly improved, and the energy loss and difficulty of ice breaking are reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely explain the technical solutions in the embodiments of the present invention. It should be noted that the embodiments of the present invention and the features therein can be combined with each other in the absence of conflict, and the embodiments described are only part of the embodiments of the present invention, not all of the embodiments.

[0018] Specific implementation 1: See Figure 1-8 To describe this embodiment, a submarine surfacing auxiliary icebreaking device based on electromagnetic resonance includes a mounting platform 1, a resonance system and a hook 6. The mounting platform 1 is set on the submarine hull, the top of the resonance system is connected to the hook 6, and the resonance system is installed in the mounting platform 1.

[0019] In this embodiment, the mounting platform 1 is a truncated cone-shaped double-layer shell without a top cover. The interlayer part is provided with multiple small holes to help the wires pass from the submarine to the surface of the magnetic part at the upper end. The resonance system includes a magnetic end 2, a spring 3 and a magnetic part 4. The spring 3 is installed between the magnetic end 2 and the magnetic part 4. The magnetic end 2 and the magnetic part 4 are respectively installed at the lower end and the upper end of the mounting platform 1. The magnetic part 4 is connected to the hook 6.

[0020] In this embodiment, an electric wire 5 is wound around the magnetic member 4, and the end of the electric wire 5 is installed in the submarine hull.

[0021] In this embodiment, when no power is supplied, the magnetic end 2 and the magnetic part 4 are attracted to each other, and when power is supplied, the magnetic end 2 and the magnetic part 4 repel each other. The base embedded in the mounting platform 1 is the magnetic end 2, and the other end above it connected to the spring 3 is the magnetic part 4. When no power is supplied, the magnetic end and the magnetic part are in a mutually attractive state. When power is supplied, the magnetic pole of the magnetic part changes with the change of the current direction.

[0022] In this embodiment, the end of each claw of the hook 6 is connected to the motor 7, and the connection between the magnetic member 4 and each claw of the hook 6 is provided with a hole 8 for passing the wire connected to the motor 7.

[0023] The mounting platform 1 is a truncated cone-shaped platform slightly larger than the magnet, and is provided with a groove to embed the magnetic part 4 therein to ensure that the resonance system is fixed on the submarine hull. The resonance system is mounted and embedded in the mounting platform 1. After the alternating current is passed between the spring 3 and the magnetic part 4 and the magnetic end 2, the top hook 6 is repeatedly vibrated up and down by the continuous attraction and repulsion force. The hook 6 at the top of the resonance system is responsible for, before the resonance system is started, through the elastic tension of the spring 3 and the mutual repulsion of the two magnets at the moment of power-on and the upward impact force assisted by the submarine, to realize that the hook 6 is tightly embedded in the ice. Then the hook naturally contracts, so that the ice follows the hook through the resonance system to continuously vibrate. According to relevant research, for a 60m*30m large For small ice blocks, when their thickness is 0.5m-2.5m, their natural frequency is 0.6Hz-11.4Hz, and the average thickness of Arctic ice is 2-4m. Therefore, the frequency of the forced vibration of the ice can be controlled within the relevant range. Finally, since the forced vibration frequency is close to the natural vibration frequency, when the frequency of the external excitation is close to the natural frequency of the ice block, the system will vibrate with a larger amplitude, thereby accumulating energy. This process of energy accumulation is not the release of energy, but the storage of energy. When the accumulated energy exceeds the limit that the system can withstand, the system will be destroyed. Only then will the energy be released, thereby achieving the effect of resonant energy concentration, allowing the submarine to produce the greatest destructive effect with less energy and complete the submarine's surfacing and icebreaking operation.

[0024] Specific implementation method 2: See Figure 1-8 This embodiment describes an icebreaking method for a submarine ascent auxiliary icebreaking device based on electromagnetic resonance, which includes the following steps: Step 1: Adjust the distance and angle between the hook 6 and the ice layer under the control of the motor 7; Step 2: After the submarine reaches the estimated position, it leaves a certain distance for surfacing; Step 3: The submarine then rises, and while rising, the magnetic element 4 is quickly energized. At this time, the magnetic element 4 and the magnetic end 2 repel each other. Under the combined action of the elastic force and magnetic force of the spring 3 and the impulse provided by the submarine's own rising, the claw 6 is quickly launched upward and shot into the ice layer; Step 4: Under the control of the motor 7, the tip of the claw 6 contracts to grab the ice layer; Step 5: Continuously change the power supply state of the magnetic part 4 to change its polarity continuously, and cooperate with the elastic force of the spring 3 to make the claw 6 vibrate up and down within a certain amplitude range, thereby driving the ice layer to resonate, and eventually causing the ice layer to break through vibration, so that the forced vibration frequency of the ice is close to the natural frequency of the ice, forming a resonant energy-gathering effect, so that the submarine can gradually gather energy around the claw 6 with less energy consumption. When the energy accumulation exceeds the limit, all the energy will be released, eventually causing the ice layer to break, which can assist the submarine to complete the task of surfacing, breaking ice and emerging from the water.

[0025] When breaking ice, first adjust the distance and angle between the claw 6 and the ice layer under the control of the motor 7. At this time, the magnetic part 4 is not energized, and it is in the stage of opposite attraction with the magnetic end 2. The magnetic force and its own weight are balanced with the elastic force of the spring 3. When the submarine reaches the estimated position, there is a floating distance left. The submarine floats up and quickly energizes the magnetic part 4. At this time, the magnetic end 2 and the magnetic part 4 are in the same repulsion. Under the combined action of the elastic force and magnetic force of the spring 3 and the impulse provided by the submarine's own floating, the claw 6 is quickly launched upward and shot into the ice layer. Then, under the control of the motor 7, the tip of the claw 6 contracts and tightly grasps the ice layer, at this time the submarine stops the surfacing process and maintains a certain distance from the ice layer, constantly changing the power supply state of the magnetic part 4 to make the polarity of the magnetic end 4 itself constantly change, and cooperate with the elastic force of the spring 3 to make the claw 6 vibrate up and down within a certain amplitude range, driving the ice layer to resonate, making the forced vibration frequency of the ice close to the natural frequency of the ice, forming a resonant energy gathering effect, so that the submarine can gradually gather energy around the claw 6 with less energy consumption. When the energy gathering exceeds the limit, all the energy will be released, eventually causing the ice layer to break, which can assist the submarine to complete the work of surfacing, breaking the ice and getting out of the water.
