Description

Technical Field

[0001] This invention relates to a device and method for remote sea ice surface blasting. Background Technology

[0002] The Arctic shipping route, known as the "Ice Silk Road," aims to traverse the Arctic Circle and connect the three major economic centers of North America, East Asia, and Western Europe. Constructing this route requires addressing challenges such as ice blockages caused by seawater freezing and ships becoming trapped in the ice. Rescuing ships with icebreakers is time-consuming, and prolonged entrapment increases the risk of accidents, seriously threatening the lives and property of those on board. Currently, icebreaking is typically done manually using explosive charges, which is time-consuming, labor-intensive, and carries inherent risks. Summary of the Invention

[0003] The purpose of this invention is to provide a remote sea ice surface blasting device and method that eliminates the need for manual deployment of explosive charges, achieves sea ice breaking tasks, and has a simple structure that is easy to implement.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A remote sea ice blasting device includes an icebreaker truck, a charge truck bed, a detonator, and a control unit. The icebreaker truck is connected to the charge truck bed, and the icebreaker truck, charge truck bed, detonator, and control unit are connected to each other.

[0006] The icebreaker includes a frame, on which a control compartment is fixedly connected. Tracks are mounted on both sides of the frame and are driven by DC motors. The rear end of the control compartment is fixedly connected to Connector 1, and the front end of the medicine bag truck bed is fixedly connected to Connector 2. Connector 1 and Connector 2 are rotatably connected by a connecting rod. The control unit is fixedly installed on the control compartment.

[0007] The medicine bag truck includes an inner bucket, an outer bucket, a cylinder, a sliding base, and a rotating shaft. One end of the outer bucket and one end of the inner bucket are rotatably connected by the rotating shaft. The other end of the outer bucket is hinged to the cylinder body of the cylinder, and the other end of the inner bucket is hinged to the piston rod of the cylinder. The sliding base includes two ice skate-shaped sliding arms, which are connected to the bottom of the outer bucket by support rods. The cylinder is connected to the control unit.

[0008] The inner chamber is equipped with a detonating cord and a storage chamber. Inside the storage chamber is placed the ice-breaking explosive charge body connected to the detonator. A photoelectric probe sensor with its bottom end extending into the storage chamber is embedded in the top of the storage chamber. The signal output terminal of the photoelectric probe sensor is connected to a crystal oscillator timer. The output terminal of the crystal oscillator timer and the input terminal of the detonator are connected to the control unit. An electric detonator is connected between the detonator and the ice-breaking explosive charge body.

[0009] The control unit includes a battery, a camera, a positioning module, a remote control module, and a solar panel. The camera is fixedly installed at the front of the control compartment. The positioning module includes a position detection / transmission unit connected to the output shaft of a DC motor. The solar panel is used to charge the battery, which provides power to the camera, positioning module, and remote control module. The camera and position detection / transmission unit are connected to the remote control module. The remote control module is connected to a solenoid valve, which is connected to a cylinder and an air source via pipelines.

[0010] The DC motor is fixed to the frame.

[0011] The bottom end of the connecting rod is threaded with a nut.

[0012] The remote control module includes a PLC, and the position detection / transmission unit includes a DC motor drive mechanism and a rotary encoder. The output shaft of the DC motor drive mechanism is connected to the rotating shaft of the rotary encoder, and the signal output terminal of the rotary encoder is connected to the I / O port of the PLC input / output module respectively.

[0013] The remote control module also includes a remote controller, which is connected to the PLC.

[0014] A remote sea ice surface blasting method, specifically including the following:

[0015] 1) When a ship is trapped by sea ice, determine the number of icebreaking explosive charges, the placement location of the icebreaking explosive charges, the number of icebreaking vehicles, and the route planning based on the extent and thickness of the sea ice.

[0016] 2) Use a drone to locate the ice-breaking explosive charge placement position, and drive a DC motor via a remote controller to make the ice-breaking vehicle reach the ice-breaking explosive charge placement position along the designated route;

[0017] 3) The remote control sends a command to raise the cylinder, and the other end of the inner container is lifted by the cylinder, causing the ice-breaking explosive pack in the inner container to slide onto the ice surface.

[0018] 4) The remote control drives the DC motor. After the icebreaker returns to the vicinity of the ship, all icebreaking explosive packages are detonated by the detonator.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. The vehicle body on both sides of the frame is equipped with tracks. The rear end of the control compartment is fixedly connected to the first connecting buckle, and the front end of the explosive pack truck bed is fixedly connected to the second connecting buckle. The first connecting buckle and the second connecting buckle are rotatably connected by a connecting rod. When a ship at sea is trapped by sea ice, the explosive device is dragged by a DC motor to move on the ice surface. The structure is simple and easy to implement.

[0021] 2. The control unit is fixedly installed in the control compartment, facilitating disassembly and maintenance.

[0022] 3. The gliding base includes two blade-shaped gliding arms, which are connected to the bottom of the outer bucket by support rods. The support rods improve balance and stability, effectively reducing swaying and tilting during gliding and improving gliding smoothness. The blade-shaped gliding arms have low friction, which reduces gliding resistance. The support rod connection ensures that the two gliding arms are parallel and symmetrical, which helps to evenly distribute the pressure during gliding and improve gliding efficiency and speed.

[0023] 4. An electric detonator is connected between the detonator and the ice-breaking explosive charge body. The detonator is connected to the control unit, which facilitates ice breaking from a distance and improves the personal safety of the operators.

[0024] 5. The icebreaking vehicle is equipped with a cargo bed for explosive charges, which can be deployed at designated points and detonated remotely, enabling rapid breaking of sea ice and emergency hazard removal.

[0025] 6. Compared to manual icebreaking, remote-controlled icebreaking is safer. Deploying shaped charge charges on the ice eliminates the need to drill holes in the ice to complete the icebreaking task. Compared to waiting for icebreaker rescue, this explosive device provides faster emergency response and is more timely. Attached Figure Description

However, the scope of protection of the present invention is not limited to the following embodiments. Unless otherwise specified, the methods used in the following embodiments are conventional methods.

[0033]

Example 1

[0034] like Figure 1 A remote sea ice blasting device includes a remote control module 1, an emergency icebreaking vehicle 2, a battery 3, a camera 4, a positioning module 5, a solar panel 6, a cargo bed 7, an icebreaking explosive charge 8, a lead wire 9, a detonator 10, and a remote controller 11. The remote control module 1, battery 3, and positioning module 5 are located inside the emergency icebreaking vehicle 2. The camera 4 is installed at the front of the emergency icebreaking vehicle 2. The solar panel 6 is located on the upper part of the emergency icebreaking vehicle 2 and is connected to the battery 3 via a wire. The emergency icebreaking vehicle 2, the cargo bed 7, battery 3, camera 4, and positioning module 5 are connected to the remote control module 1 via a data cable 12. The cargo bed 7 is connected to the rear of the emergency icebreaking vehicle 2 via a connecting rod 13. The detonator 10 and the icebreaking explosive charge 8 are connected via the lead wire 9. The camera uses the authorization announcement number CN207022101U and is named "Ultra-wide Camera," but other types can also be used.

[0035] The emergency ice-breaking vehicle 2 includes a track 14 at the bottom and a control compartment 15 at the top. The track 14 has an idler wheel 16 at the front and a drive wheel 17 at the rear. The drive wheels on both sides are connected to DC motors, and the steering function is achieved by differential rotation on both sides. The control compartment 15 on the top of the emergency ice-breaking vehicle 2 has an arc-shaped structure at the front and a square structure at the rear. A round handle-shaped connecting buckle 18 is connected to the square structure, which can be connected to the medicine bag hopper 7 through a connecting rod 13.

[0036] See Figure 3 The remote control module 1 is a Siemens S7-300 plc with 1 master and 4 slave MODBUS RTU wireless communication function. The remote controller 11 is a Siemens MP277 with an antenna 19. The remote control module 1 is connected to the motor of the track 14 and the electric support rod of the cylinder 22 via data cable 12. The connection between the remote controller and the Siemens S7-300 plc communication module CP341 is realized, and the control commands of the remote controller 11 are remotely transmitted to the remote control module 1. The remote control module 1 remotely controls the emergency icebreaker 2 to take pictures, walk, turn, and release the icebreaking explosive pack 8 from the explosive pack 7 in the explosive pack 7.

[0037] See Figure 1The solar panel 6 is connected to the battery 3. The solar panel 6 converts solar energy into electrical energy and stores it in the battery 3. The battery 3 is a Siemens PS307 (5A). The power is distributed to other devices through the settings of the remote control module 1. The positioning module 5 is a SUN-NVC500 high-precision positioning module, which can accurately locate the specific position of the emergency icebreaker 2, which is beneficial for the deployment of the icebreaking explosive pack 8 and the retrieval of the emergency icebreaker 2.

[0038] See Figure 2 The medicine bag 7 includes a round handle-shaped connecting buckle 18, an outer bucket 20, an inner bucket 21, a cylinder 22, a sliding base 23, and a rotating shaft 24. The outer bucket 20 and the inner bucket 21 are connected to the rotating shaft 24 via the cylinder 22. Both are trapezoidal empty boxes with a front-high and rear-low design, closed at the front and open at the rear. The round handle-shaped connecting buckle 18 is located on the outside and at the front, and can be connected to the emergency icebreaker 2 via a connecting rod 13. The rotating shaft 24 is located behind the outer bucket 20 and the inner bucket 21. The sliding base 23 includes two ice blade-shaped sliding arms 25. The two sliding arms 25 are connected to the bottom of the outer bucket 20 via a support rod 26. The cylinder 22 is installed on the upper surface of the outer bucket 20 and the lower surface of the inner bucket 21. When the remote controller 11 sends a control command to the remote control module 1, commanding the cylinder 22 to rise, the front of the inner bucket 21 is lifted by the electric support rod of the cylinder 22, causing the ice-breaking explosive bag 8 in the inner bucket 21 to slide onto the ice surface.

[0039] See Figure 4 The ice-breaking explosive charge 8 includes a detonation hole 27, a charging hole 28, a storage chamber 29, a support 30, a triangular cover 31, and an electric detonator 32. The storage chamber 29 is filled with explosives, and the electric detonator 32 is inserted from the detonation hole 27 to the middle position of the storage chamber 29.

[0040] A method for remote sea ice surface blasting includes the following steps:

[0041] 1) When a ship is trapped by sea ice, the number of icebreaking explosive charges 8, the placement location of icebreaking explosive charges 8, the number of emergency icebreaking vehicles 2, and the route planning are determined based on the specific situation of the sea ice disaster, the average thickness of the sea ice determined by artificial drilling, and the sea ice parameters.

[0042] 2) Assemble and inspect the blasting device, fill it with explosives and electric detonators 32, and ensure that the blasting device can perform the ice-breaking task without failure.

[0043] 3) Use drones to locate the ice-breaking explosive charge placement position, start each group of emergency ice-breaking vehicles 2 to carry out the charge placement task, and use remote controller 11 to control the emergency ice-breaking vehicle 2 to reach the designated position and release the ice-breaking explosive charge 8.

[0044] 4) Control all emergency icebreakers 2 with explosive charge 7 to return to the vicinity of the ship via remote control 11, lower the box-shaped tray without baffle on one side on the ship, retrieve the emergency icebreakers 2 and explosive charge 7, and detonate all icebreaking explosive charges 8 via detonator 10.

[0045] 5) Collect and analyze the effects of sea ice breaking through real-time observation using drones.

[0046]

Example 2

[0047] The Northern Hemisphere is experiencing a widespread cold wave, causing significant difficulties for logistics and transportation in various regions. Affected by sea ice, a Chinese-flagged vessel, already stranded, immediately organized a drone-based icebreaking operation to save itself.

[0048] The specific process implementation steps are as follows:

[0049] 1) When a ship is trapped by sea ice, an icebreaking plan is formulated based on the sea ice range of 5km and the sea ice thickness of 400mm. The number of icebreaking explosive charges 8 is determined to be 10, the placement of icebreaking explosive charges 8 is in a straight line, the explosive charge is 20kg, and the number of emergency icebreaking vehicles 2 is 4. The placement of icebreaking explosive charges is located by drone, and the route is planned based on the shortest distance between the target location and the current location.

[0050] 2) Assemble and inspect the blasting device, fill it with explosives and electric detonators 32, and ensure that the blasting device can perform the ice-breaking task without failure.

[0051] 3) Activate each group of emergency icebreakers 2 to carry out the task of placing explosive charges. Use remote control 11 to control the emergency icebreakers 2 to reach the designated location and release the icebreaking explosive charges 8.

[0052] 4) Control all emergency icebreakers 2 with explosive charge 7 to return to the vicinity of the ship via remote controller 11, retrieve emergency icebreakers 2 and explosive charge 7, and detonate all icebreaking explosive charges 8 via detonator 10.

[0053] The vehicle body of this invention is equipped with tracks on both sides of the chassis. The rear end of the control compartment is fixedly connected to connecting buckle one, and the front end of the medicine bag truck bed is fixedly connected to connecting buckle two. Connecting buckle one and connecting buckle two are rotatably connected by connecting rods. When a ship encounters sea ice at sea, a DC motor drives the blasting device to move on the ice surface. The structure is simple and easy to implement. The control unit is fixedly installed in the control compartment, which is convenient for disassembly and maintenance. The gliding base includes two ice blade-shaped gliding arms, which are connected to the bottom of the outer bucket by support rods. The two ice blade-shaped gliding arms improve balance and stability, effectively reducing swaying and tilting during gliding and improving the smoothness of gliding. With its low-friction characteristics, it reduces sliding resistance. The support rod connection ensures the parallelism and symmetry of the two sliding arms, which is conducive to the even distribution of pressure during sliding and improves sliding efficiency and speed. An electric detonator is connected between the detonator and the ice-breaking explosive charge body. The detonator is connected to the control unit, which facilitates long-distance ice breaking and improves the personal safety of operators. The ice-breaking vehicle carries the explosive charge in a cargo bed, which carries the ice-breaking explosive charge for targeted deployment and remote detonation, realizing rapid sea ice breaking and emergency hazard removal. Compared with manual ice breaking, remote-controlled ice breaking is safer. Ice breaking can be completed without drilling holes in the ice by deploying shaped charge on the ice. Compared with waiting for icebreaker rescue, this blasting device is faster and more timely in emergency hazard removal.
