Description

Technical Field

[0001] The present invention belongs to the technical field of water body ice breaking, and in particular relates to an ice breaking system and an ice breaking method thereof. Background Art

[0002] In various activities in the Arctic and Antarctic regions, as well as in the rivers and lakes in northern my country in winter, an operation requiring large investment and very high technical difficulty is often required - icebreaking. In daily life, it is mainly used to open up waterways; in addition, icebreaking is also needed during ice rescue to improve rescue efficiency.

[0003] Currently, the primary tool for surface icebreaking is an icebreaker. These vessels rely on their own power and mass, using their bow to split the ice or their hull to crush it with its own weight after driving onto it. If the vessel becomes stuck, it can also rock its hull to break ice. These methods all rely on the vessel's own power and mass. Icebreakers require heavy steel plates and powerful engines, leading some to use expensive nuclear propulsion. However, no matter how large an icebreaker is, its power and mass are limited, resulting in limitations in icebreaking capabilities. Breaking through some very thick, stagnant ice remains challenging. Furthermore, icebreakers are limited in their ability to break through ice in shipping lanes, and their range and angles of operation are limited.

[0004] Based on the defects of the existing technology, there is an urgent need in this field to propose an icebreaking system and an icebreaking method thereof that are different from traditional technologies, so as to solve the defects of the existing technology. Summary of the Invention

[0005] The purpose of the present invention is to provide an icebreaking system that overcomes the limitations of the mass and power of traditional icebreakers, reduces icebreaking investment and costs, expands icebreaking application scenarios, and expands icebreaking angles and ranges.

[0006] The technical solution adopted to achieve the purpose of the present invention is:

[0007] An icebreaking system includes a carrying device, an airbag, a traction device and a gas control device, wherein the gas control device is placed on the carrying device and is fixedly connected to one end of the airbag through a gas pipeline; the traction device is fixedly connected to the other end of the airbag; and also includes a central control module for controlling the traction device.

[0008] Furthermore, the number of airbags is more than one, and the number of gas control devices and gas pipelines matches the number of airbags.

[0009] Furthermore, the traction device includes a power device, a camera and a position sensor.

[0010] Furthermore, a protective frame is provided outside the airbag, and one end of the protective frame is fixedly connected to the gas pipeline.

[0011] Furthermore, the gas control device includes an inflation device and an exhaust device; the gas delivery pipeline includes an inflation pipe and an exhaust pipe, wherein one end of the inflation pipe is fixedly connected to the airbag, and the other end is fixedly connected to the output end of the inflation device; one end of the exhaust pipe is fixedly connected to the airbag, and the other end is fixedly connected to the output end of the exhaust device.

[0012] Furthermore, a first one-way valve is provided on the inflation pipe, and a second one-way valve is provided on the exhaust pipe.

[0013] Furthermore, the inflation pipe and the exhaust pipe on the same gas control device are arranged in a flexible pipe.

[0014] Another object of the present invention is to provide an ice-breaking method that is simple to operate, easy to implement, and highly practical.

[0015] The technical solution adopted to achieve another object of the present invention is:

[0016] An ice-breaking method specifically comprises the following steps:

[0017] Step S1, placing the airbag into water under the ice layer;

[0018] Step S2: The central control module controls the traction device to dive under the ice layer to prepare for the ice-breaking position, and transmits the ice layer underwater situation information back to the central control module;

[0019] Step S3, by manipulating the gas control device to inflate and deflat the airbag, the ice layer is partially lifted upward or the ice layer is vibrated up and down, thereby breaking the ice layer and achieving ice breaking.

[0020] The beneficial effects of the present invention are:

[0021] 1. The present invention overcomes the limitations of traditional icebreakers in terms of mass and power, reduces icebreaking investment and cost, and expands icebreaking angles and ranges.

[0022] 2. The present invention changes the traditional self-damaging or parallel icebreaking method to a bottom-up icebreaking method. When the traditional top-down method is used, the water body has a strong bearing capacity, which has a certain offsetting effect on the gravity of the gravity icebreaker, resulting in poor icebreaking effect; when the bottom-up icebreaking method of the present invention is used, the ice layer is relatively easier to break because the air has no bearing capacity.

[0023] 3. This invention expands the airbags by inflating them. This creates a significant upward buoyancy in the water, partially lifting the ice. Simultaneously, the ice itself exerts a downward force. Combined with the supporting force of the airbags and the ice's gravity, the ice experiences a significant shear force, causing it to break. In this invention, the buoyancy generated by the inflated airbags is not limited by the mass or power of the icebreaker itself, but only by the amount of air inflated. This allows for substantial buoyancy, enabling challenging icebreaking missions.

[0024] 4. The present invention can rapidly inflate and deflat the airbag to cause different parts of the ice layer to rise or fall with the airbag, thereby causing the ice layer to vibrate violently and causing the hard ice layer to break quickly.

[0025] 5. The present invention overcomes the defect that existing icebreaking vessels are limited to the route range. The system of the present invention can deploy multiple airbags for icebreaking to any position and range, and airbags in different directions can act simultaneously to achieve all-round icebreaking.

[0026] 6. When a ship is trapped, the system of the present invention can be used to break ice and save the ship. Icebreaking in water bodies can also be performed on land without relying on icebreakers. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the following will be a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work shall fall within the scope of protection of the present invention.

[0038] like Figures 1 to 4 and Figure 8 As shown, an ice-breaking system includes a carrying device 1, an airbag 2, a traction device 3 and a gas control device 4, wherein the gas control device 4 is placed on the carrying device 1, and the gas control device 4 is fixedly connected to one end of the airbag 2 through a gas pipeline 5; the traction device 3 is fixedly connected to the other end of the airbag 2; and also includes a central control module 6 for controlling the traction device 3.

[0039] The carrier 1 of the present invention primarily serves the purpose of carrying and storing objects, and can be adjusted in practice to accommodate changes in salvage scenarios. When breaking ice on land, the carrier 1 does not need to enter the ice or water surface. The carrier 1 is placed on land and can be a car or other loading container with universal wheels. If the carrier 1 needs to enter the water, it can be an existing icebreaker or other vessel that can perform the load-bearing function.

[0040] The airbag 2 is made of a flexible, water-tight, air-tight and inelastic flexible material. It floats on the water surface under the ice layer under the buoyancy of water, thereby partially lifting the ice layer on the water surface.

[0041] The primary function of traction device 3 is to pull airbag 2 underwater. It can be an underwater robot or a remotely operated submersible commonly found in the prior art. Its underwater movement follows existing principles, such as the remotely operated submersible disclosed in Patent Publication No. CN106275329A. In the present invention, traction device 3 is connected to the end of airbag 2 by a rope. Furthermore, if airbag 2 is provided with a protective frame 10, traction device 3 can also be connected to protective frame 10 via a rope.

[0042] Gas control device 4 is an air pump that can inflate or deflat, thereby inflating or defusing airbag 2. When gas pipeline 5 is a single unit, gas control device 4 is a bidirectional air pump. When gas pipeline 5 is divided into an inflation pipe 501 and a deflation pipe 502, each pipe 501 and each pipe 502 corresponds to a unidirectional air pump. The air pump associated with inflation pipe 501 inflates airbag 2, while the air pump associated with deflation pipe 502 deflates airbag 2.

[0043] The central control module 6 is the control center of the present invention, which can be specifically set on the carrying device 1. It is mainly wirelessly connected to the traction device 3 to realize wireless remote control of the traction device 3; the central control module 6 is also connected to the gas control device 4, thereby changing the working state of the gas control device 4. The connection method between the central control module 6 and the gas control device 4 is the same as the connection method between the existing common electric air pump and the control center, such as the connection method between the electric air pump and its control module in the patent with publication number CN111852827A.

[0044] like Figure 2 As shown, in one embodiment of the present invention, the number of airbags 2 is more than one, and the number of gas control devices 4 and gas pipelines 5 matches the number of airbags 2 .

[0045] The purpose of having more than one airbag 2 is to place the airbag 2 at different positions under the ice layer to form an ice-breaking route and achieve all-round ice-breaking.

[0046] The traction device 3 includes a power unit, a camera, and a position sensor. The function of the power unit on the traction device 3 is to drive it to move underwater. In one embodiment of the present invention, the traction device 3 is a remote-controlled submersible in the prior art, specifically the remote-controlled submersible disclosed in patent CN106275329A. The driving principle of the power unit in the present invention is the same as the principle of the driving device in the patent. The camera and position sensor are both devices in the prior art. The purpose of their installation on the traction device 3 is to obtain images and position information of the underwater icebreaking position. Other sensors can be installed on the traction device 3 of the present invention according to actual needs. Various sensors monitor all situations in a timely manner and transmit information back to the operator in a timely manner so that the operator can operate accurately according to the actual situation.

[0047] In one embodiment of the present invention, a vibration measuring device is also provided on the traction device 3. The vibration measuring device can measure the vibration frequency of the ice layer. The central control module 6 calculates the optimal inflation and deflation time relationship and the inflation and deflation speed of the airbag 2 based on the measurement results. The gas control device 4 inflates and deflates the airbag 2 based on the calculated results, causing the corresponding ice layer to resonate and accelerate the fracturing of the ice layer. The vibration measuring device in this embodiment is a common vibration measuring device in the prior art, such as the vibration measuring device disclosed in patent authorization number CN103364068B. The function of the vibration measuring device in the present invention is to measure the vibration frequency of the ice layer. In other embodiments of the present invention, the vibration measuring device can also be provided on the airbag 2.

[0048] like Figure 3 As shown, a protective frame 10 is provided on the outside of the airbag 2, one end of which is fixedly connected to the gas pipeline 5. The purpose of the protective frame 10 is, on the one hand, to prevent the airbag 2 from contacting the ice layer, thereby preventing the airbag 2 from being scratched by the ice layer; on the other hand, it ensures that the airbag 2 maintains a certain shape after inflation, ensuring that the weight of the ice layer does not cause the airbag 2 to deform under pressure, thereby affecting the ice-breaking effect.

[0049] In actual use, a protective frame 10 is added to the airbag 2 only when special operations are required, such as for difficult ice-breaking operations such as those involving thick ice. The protective frame 10 can be made of a hard material such as plastic, wood, or metal. The protective frame 10 is divided into an upper and lower part, with the lower part being made of a heavier hard material than the upper part, to ensure that the airbag 2 does not turn upside down or change its angle.

[0050] In one embodiment of the present invention, the protective frame 10 is a hollowed-out frame in a cubic, spherical, elliptical, triangular, or other shape. It is secured to the end of the gas pipeline 5, specifically by a tying rope. In this embodiment, the end of the airbag 2 not connected to the gas pipeline 5 is secured to the protective frame 10 via a rope to prevent the airbag 2 from escaping the frame during inflation. Furthermore, in the present invention, the traction device 3 is connected to the end of the airbag 2 by a rope. In addition to the protective frame 10 provided on the airbag 2, the traction device 3 can also be connected to the protective frame 10 via a rope.

[0051] In other embodiments of the present invention, the protective frame 10 may also be a foldable protective frame 10 for easy storage, specifically a foldable frame commonly found in the prior art, such as the foldable frame disclosed in patent authorization number CN111406028B.

[0052] like Figure 3 and Figure 4As shown, the gas control device 4 includes an inflation device 401 and an exhaust device 402; the gas transmission pipeline 5 includes an inflation tube 501 and an exhaust tube 502, wherein one end of the inflation tube 501 is fixedly connected to the airbag 2, and the other end is fixedly connected to the output end of the inflation device 401; one end of the exhaust tube 502 is fixedly connected to the airbag 2, and the other end is fixedly connected to the output end of the exhaust device 402.

[0053] The use of the inflation device 401 in conjunction with the exhaust device 402 can cause the ice layer to vibrate violently and break. The specific process is as follows: according to the planned inflation and deflation plan, the inflation device 401 inflates part of the hose 9 and the airbag 2, causing the ice layer to rise locally; when it is inflated to a specified amount, the air is quickly exhausted, and at the same time, the other part of the airbag 2 is quickly inflated according to the plan; this staggered inflation and exhaust are repeated to cause the ice layer to vibrate violently, prompting it to generate and expand cracks, and eventually break.

[0054] like Figure 3 and Figure 4 As shown, the inflation pipe 501 is provided with a first one-way valve 7 , and the exhaust pipe 502 is provided with a second one-way valve 8 .

[0055] The purpose of setting a one-way valve is to make the gas move in the same direction without backflow. Under the action of the first one-way valve 7, the inflation tube 501 only delivers gas into the airbag 2; under the action of the first one-way valve 7, the exhaust tube 502 only extracts the rest of the airbag 2. The first one-way valve 7 in the present invention can be set at any position on the inflation tube 501, and the second one-way valve 8 can be set at any position on the exhaust tube 502. In order to facilitate installation and disassembly, the present invention preferably sets the first one-way valve 7 at the output port of the inflation device 401, and sets the second one-way valve 8 at the outlet where the airbag 2 is connected to the exhaust tube 502. The first one-way valve 7 and the second one-way valve 8 are both common one-way valves in the prior art. The specific model to be used can be selected according to actual conditions, as long as it can control the one-way flow of gas.

[0056] like Figure 3 and Figure 4 As shown, the gas filling pipe 501 and the gas extraction pipe 502 on the same gas control device 4 are arranged in a hose 9.

[0057] Placing the inflation pipe 501 and the exhaust pipe 502 on the same gas control device 4 in one hose 9 can prevent the inflation pipe 501 and the exhaust pipe 502 from being entangled with each other, making it easier to arrange and store.

[0058] In one embodiment of the present invention, the inflation tube 501 and the exhaust tube 502 on the same gas control device 4 are secured using a plurality of securing devices 11, which may be ropes or cable ties. Securely securing the inflation tube 501 and the exhaust tube 502 on the same gas control device 4 using the securing devices 11 and then inserting them into the hose 9 prevents the inflation tube 501 and the exhaust tube 502 from becoming entangled with each other.

[0059] In the present invention, to prevent the traction device 3 from being unable to be returned to the vicinity of the carrier device 1 after it loses control, a rope can be used to connect the airbag 2 and the traction device 3 to the carrier device 1, thereby preventing difficulty in recovering the traction device 3 after a failure. When setting up the rope, the rope can be designed to be longer, and the excess portion can be reeled onto the carrier device 1 using a reeling device.

[0060] An ice-breaking method specifically comprises the following steps:

[0061] Step S1, placing the airbag 2 into water under the ice layer;

[0062] Step S2, the central control module 6 controls the traction device 3 to dive under the ice layer to prepare for the ice-breaking position, and transmits the ice layer underwater situation information back to the central control module 6;

[0063] In step S3, the gas control device 4 is operated to inflate and deflate the airbag 2, thereby partially lifting the ice layer upward or vibrating the ice layer up and down, thereby breaking the ice layer and achieving ice breaking.

[0064] The method of the present invention has different specific operations in different scenarios. The specific ice-breaking method and operation process are as follows:

[0065] 1. Icebreaking Operations under Conventional Conditions

[0066] Step 1: Take out the traction device 3, the air pipeline 5 and the air bag 2 from the carrying device 1 and slowly put them into water.

[0067] In step 2, the central control module 6 is used to remotely control the traction device 3 to pull the gas pipeline 5 underwater and provide real-time feedback. After analysis by the central control module 6, the optimal icebreaking position is confirmed and the traction device 3 is moved below the optimal icebreaking point.

[0068] In step 3, the inflation device 401 inflates the airbag 2 through the inflation tube 501. Under the action of the first one-way valve 7, the gas in the inflation tube 501 flows unidirectionally into the airbag 2, so that the airbag 2 is inflated and expanded. The inflated airbag 2 receives buoyancy and exerts upward pressure on the ice layer. At the same time, the various sensors of the traction device 3 monitor the shape change, floating condition and ice layer vibration frequency of the airbag 2 in real time, and transmit the detection information back to the central control module 6 in real time for the operator's reference.

[0069] In step 4, the operator performs accurate operations according to the information sent back by the traction device 3 until the ice at the location of the airbag 2 is successfully broken.

[0070] Step 5: After the ice is broken successfully, the exhaust device 402 is started to extract the gas in the airbag 2 to reduce the resistance of the airbag 2 moving in the water, and the traction device 3 is controlled to move to a new ice-breaking point to carry out the next ice-breaking operation.

[0071] 2. Icebreaking Operations for Super Thick Old Ice

[0072] The specific operation process is shown in the figure Figures 5 to 7 shown.

[0073] Step 1: Develop an icebreaking plan, determine the number of gas pipelines 5 and traction devices 3 to be used, control the navigation routes of the traction devices 3 to ensure that the navigation routes do not intersect or overlap, and develop an inflation and degassing plan. In this step, the inflation pipe 501 and degassing pipe 502 in the gas pipeline 5 can be selected from conventional inflation pipes 501 and conventional degassing pipes 502 or rapid inflation pipes 501 and rapid degassing pipes 502 according to actual conditions.

[0074] In step 2, each traction device 3 and its corresponding air pipeline 5 and air bag 2 are slowly placed into the water from different positions on the carrying device 1.

[0075] In step 3, the central control module 6 remotely controls the traction device 3 to pull the gas pipeline 5 underwater, providing real-time feedback. The operating system confirms the optimal ice-breaking position for each airbag 2, and the traction device 3 moves to the appropriate location. During this step, if a protective frame 10 is attached to the airbag 2, partial gas can be introduced immediately after the airbag 2 enters the water to ensure that the weight of the airbag 2 and the protective frame is equal to the buoyancy of the water, facilitating traction by the traction device 3.

[0076] In step 4, according to the planned inflation and deflation plan, the inflation device 401 inflates part of the airbags 2 to cause the ice layer to rise locally. When the air is inflated to the specified amount, the air is quickly deflated. At the same time, the other part of the airbags 2 is quickly inflated according to the plan. The repeated staggered inflation and deflating causes the ice layer to vibrate violently, prompting the ice layer to produce and expand cracks and eventually break.

[0077] Step 5. For more difficult icebreaking operations, a vibration measuring device is installed on the top of the airbag 2 or the traction device 3 to measure the vibration frequency of the ice layer. Based on the measurement results, the optimal inflation and exhaust time relationship and inflation and exhaust speed of the airbag 2 at each point are calculated, and the inflation and exhaust are controlled based on the calculated results to make the ice layer resonate and accelerate the ice layer fracture.

[0078] Step 6: After the ice is broken successfully, the exhaust device 402 is started to extract the gas in the airbag 2 to reduce the resistance of the airbag 2 moving in the water, and the traction device 3 is controlled to move to a new ice-breaking point to carry out the next ice-breaking operation.

[0079] 3. All-round and large-scale icebreaking operations

[0080] The first step is to formulate an icebreaking plan, draw up the ice fracture line, determine the number of gas pipelines 5 and traction devices 3 to be used, and the submarine navigation route plan, etc.

[0081] In step 2, each traction device 3 and its corresponding air pipeline 5 and air bag 2 are slowly placed into the water from different positions on the carrying device 1.

[0082] In step 3, the central control module 6 remotely controls the traction device 3 to pull the gas pipeline 5 underwater, providing real-time feedback. The operating system confirms the optimal ice-breaking position for each airbag 2, and the traction device 3 moves to the appropriate location. During this step, if a protective frame 10 is attached to the airbag 2, partial gas can be introduced immediately after the airbag 2 enters the water to ensure that the weight of the airbag 2 and the protective frame is equal to the buoyancy of the water, facilitating traction by the traction device 3.

[0083] In step 4, according to the planned inflation and deflating plan, the inflation device 401 inflates part of the hose 9 and the airbag 2, causing the ice layer to rise locally and break. The mini-submarine monitors all conditions in real time and transmits information back to the operator in a timely manner so that the operator can accurately operate according to the actual situation;

[0084] According to the planned inflation and deflation plan, the inflation device 401 inflates part of the airbag 2, causing the ice layer to rise locally and then break under the action of shear force.

[0085] Step 5: After the ice is broken successfully, the exhaust device 402 is started to extract the gas in the airbag 2 to reduce the resistance of the airbag 2 moving in the water, and the traction device 3 is controlled to move to a new ice-breaking point to carry out the next ice-breaking operation.

[0086] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described with reference to the preferred embodiments of the present invention, it should be understood by those skilled in the art that various changes can be made in form and details without departing from the spirit and scope of the present invention as defined in the appended claims.
