Description

Technical Field

[0001] The present invention relates to the technical field of ship and ocean engineering, and in particular to a polar shipborne ultra-high voltage pulse discharge bubble icebreaking system and method. Background Art

[0002] In recent years, with the reduction of polar sea ice, the development of Arctic shipping routes and polar resources has become increasingly realistic. The Arctic has an important ecological, economic, resource and military status, and is important for polar exploration in national development plans. The polar region has become a strategic area related to national interests.

[0003] The Arctic route is an emerging golden route that can shorten the traditional Asia-Europe route by 5,000-6,000 kilometers. It is the shortest route connecting Asia, Europe and America. It is one of the three major blue economic channels and is of great significance to reducing transportation costs and strengthening global trade links. The Arctic is rich in mineral resources, including 13% of the world's oil reserves and 30% of undeveloped natural gas. In addition, the Arctic's rare metals, marine resources and rich fishery resources also have increasingly obvious commercial value. Therefore, the Arctic is an important energy and resource base in the future. At the same time, the military geographical location of the Arctic is also very important. The Arctic is the junction of Asia, Europe and America, and is the shortest distance for weapons to strike. However, the large area of ​​ice in the Arctic can provide natural protection for strategic nuclear submarines. Therefore, whoever dominates the Arctic will be able to gain the "commanding heights" of the world's military. It can be seen that its military strategic significance is high, so the development and utilization of resources in the Arctic route has a huge impact on my country's energy strategy and economic development.

[0004] Icebreakers and explosive icebreaking are currently the two main methods of icebreaking. Once an icebreaker is trapped in extremely bad weather, it is difficult to rely on its own power to get out of trouble. Explosive icebreaking detonates explosives in the ice layer, which can easily interfere with the marine ecology and cause water pollution. These two methods are difficult to meet polar environmental protection regulations and usage requirements. Ultra-high pressure pulsating bubble icebreaking technology has great potential in polar exploration and resource development due to its advantages of safety, efficiency, green environmental protection, and repeatability. It is a means to improve the polar navigation capability of ships and assist in icebreaking. Summary of the invention

[0015] Furthermore, based on the ice thickness measurement results, the point with the smallest ice thickness is selected, and then the hole arrangement plan is determined. The energy for generating bubbles can be determined based on the ice thickness and the hole arrangement plan. After the specific positions of the holes are determined, the drilling robot can be placed above the ice layer, and the staff on the hull observe the images transmitted by the camera installed on the drilling robot through a computer. After reaching the designated position, the drilling robot is controlled by a computer to start drilling. After drilling through the ice layer, the robot is controlled to place the electrode under the ice layer.

[0016] The present invention also proposes an icebreaking method based on the polar shipborne ultra-high voltage pulse discharge bubble icebreaking system, the icebreaking method comprising:

[0017] Step 1, connect the phase difference meter to the sound wave generator and the sound wave receiver, turn on the switch, the sound wave generator emits sound waves, for a period of time, the receiver receives the signal, and the phase difference meter measures the time difference;

[0049] The system of the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] The system of the present invention is mainly used to help the ship break the ice to complete self-rescue or help other ships get out of trouble when the ship is trapped in ice in the polar regions.

[0051] The present invention proposes a polar shipborne ultra-high voltage pulse discharge bubble icebreaking system, which includes three modules: a point selection module, a drilling and electrode arrangement module, and an ultra-high voltage pulse bubble generation module. These three modules work together to complete the function of the system of the present invention. This embodiment takes 3 meters of ice thickness as an example.

[0052] First, the point selection module determines the specific working point of the system described in the present invention, and then the drilling and electrode arrangement module completes the drilling and electrode arrangement. Finally, the ultra-high voltage pulse bubble generation module generates ultra-high voltage pulse bubbles to achieve ice breaking.

[0053] The point selection module includes an ice thickness detection system, energy size selection, and hole position arrangement scheme. The module uses an acoustic wave detection system to detect the real-time thickness of the ice layer. The acoustic wave detection system includes an acoustic wave generator, an acoustic wave receiver, and a phase difference meter.

[0054] First, install the sound wave generator and the sound wave receiver above the ice layer that needs to be detected, and then connect the sound wave generator and the sound wave receiver to the phase difference meter. After the connection is completed, turn on the control switch, the sound wave generator starts to emit sound waves to the ice layer, and the sound waves are reflected by the ice layer. After a short period of time, the sound wave receiver can receive the reflected sound wave signal. At this time, the phase difference meter can measure the phase difference of the sound wave, and then by calculating the measured phase difference, the real-time thickness of the ice layer can be obtained.

[0055] After that, the safe and vulnerable points are determined by combining the real-time thickness of the ice with the position of the hull;

[0056] When the ice thickness is about 3 meters, the present invention adopts a double hole arrangement scheme, and the center distance between the two holes is 1 meter;

[0057] According to the ice thickness and hole arrangement plan, the bubble radius required to be generated is 3 meters, and the voltage required to generate the bubble is 20,000 volts;

[0058] Next, the drilling robot is placed above the ice layer, and the staff on the ship use a computer to observe the images transmitted by the camera installed on the drilling robot to ensure that the drilling robot reaches the designated position accurately. After reaching the designated position, the drilling robot is controlled by the computer to start drilling;

[0059] After drilling through the ice layer, control the robot to place the electrode 1.5 meters below the ice layer. After the electrode is placed according to regulations, the work content of the drilling and electrode arrangement module is completed.

[0060] After the above preparations are completed, the UHV pulse bubble generation module can be used to generate UHV pulsating bubbles. Connect the controller, electrical box and booster of the module. After the connection is completed, set the voltage parameter on the controller to 20,000 volts; turn on the control switch, the electrical box starts to work, generates voltage, the booster boosts it, and the electrode discharges underwater to generate UHV pulsating bubbles; under the action of multiple UHV pulsating bubbles, the ice layer is broken, the hull is freed, and finally the electrode is retrieved.
