Description

Technical Field

[0001] The present invention relates to the technical field of underwater equipment deployment, and particularly to a floating ice clearing device for ice layer explosion opening. Background Art

[0002] In polar regions, when deploying underwater equipment such as unmanned submarines, there is a situation where the deployment waters are covered by ice. For this reason, ice breaking treatment can be carried out on the ice surface through explosives, etc. Specifically, by detonating explosives on the ice surface, a large amount of broken ice will be generated at the opening of the ice surface, presenting a spider web structure as shown in Figure 1 . Among them, small broken ice has little impact on the subsequent deployment of underwater equipment. First, observe the blasting area. If the opening is all small ice blocks, the underwater equipment can be directly deployed into the water quality. If there are large broken ice at the opening, further treatment is required.

[0003] Currently, most use the method of secondary blasting for treatment. However, it is difficult to ensure that the large fragments can be completely cleaned by the secondary blasting method, and at the same time, it will cause further impact on the environment.

[0004] The blasted ice blocks float on the water surface. As time goes by, small ice blocks will adsorb on the edge of the large broken ice and bond together over time, resulting in the volume of the large broken ice gradually increasing, affecting the deployment of equipment. Therefore, it is necessary to clean the large broken ice in time. Summary of the Invention

[0005] In view of this, it is necessary to provide a floating ice clearing device for ice layer explosion opening to solve the problem that after blasting, the ice blocks float on the water surface. As time goes by, small ice blocks will adsorb on the edge of the large broken ice and bond together over time, resulting in the volume of the large broken ice gradually increasing, affecting the deployment of equipment. Therefore, it is necessary to clean the large ice in time.

[0006] The present invention provides a floating ice clearing device for ice layer explosion opening, including a frame, a force arm assembly and an ice grasping assembly. The force arm assembly includes a side plate and a telescopic member. The bottom end of the side plate is hinged to the side wall of the frame. The telescopic member is arranged above the side plate and hinged to the frame. The output end of the telescopic member is slidably and hinged to the side plate. The telescopic member is used to drive the side plate to rotate relative to the frame. The ice grasping assembly includes a slider, a spike and a driving member. The slider is slidably connected to the side plate along the length direction of the side plate. The spike is connected to the side of the slider away from the telescopic member. The driving member is installed on the side plate, and the output end of the driving member is connected to the slider for driving the slider to slide.

[0007] Further, the frame includes a fuselage, a cone, and a buoyancy body. The fuselage is cylindrical. The top of the cone is fixedly connected to the bottom of the fuselage. The bottom of the cone forms a tip. The buoyancy body is installed on the side wall of the fuselage. Both the side plate and the telescopic member are hinged to the fuselage.

[0008] Further, the frame further includes a power member. The power member is installed on the side wall of the fuselage and is located at a position between the buoyancy body and the cone. The vertical distance from the buoyancy body to the fuselage is less than the radius of the cone and the radius of the buoyancy body.

[0009] Further, the side plate is hinged to the middle part of the frame, and the telescopic member is hinged to the side wall at the top of the fuselage.

[0010] Further, the device further includes floating plates installed on both sides of the side plate.

[0011] Further, the number of the force arm assemblies is multiple, and the multiple force arm assemblies are evenly arranged along the circumferential direction of the frame.

[0012] Further, the number of the sliders is multiple, and the multiple sliders are arranged in sequence along the length direction of the side plate. A plurality of pins are installed on each slider.

[0013] Further, the driving member includes a conveyor belt and a support slide plate installed on the side plate. One side of the slider is fixedly connected to the conveyor belt, and the other side of the slider is slidably connected to the support slide plate.

[0014] Further, the ice grasping assembly further includes a jacking member installed on the slider. The pin is slidably connected to the slider along its length direction. The output end of the jacking member is connected to the top end of the pin for driving the pin to slide.

[0015] Further, the ice grasping assembly further includes a limiting plate fixedly connected to the side plate. The limiting plate is arranged on the side of the side plate away from the telescopic member and is parallel to the side plate. The pin penetrates through a strip-shaped through groove formed in the limiting plate.

[0016] Compared with the prior art, after the ice surface explodes to form an opening, the ice cleaning device can be placed into the opening. As the device floats on the water surface and moves to a position close to large ice chunks, the telescopic member drives the vertically arranged side plate to move in the horizontal direction, and the pins on the slider are driven into the large ice chunks. The frame drives the large ice chunks to move to a position close to the ice layer. The telescopic member drives the side plate to rotate, so that the side of the side plate close to the ice layer tilts up until the tilted side of the ice chunk is higher than the ice layer. The driving member drives the slider to move until the grasped large ice chunk is moved onto the ice layer, thus completing the cleaning work of the large ice chunks.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The following will specifically describe the preferred embodiments of the present invention in conjunction with the drawings. The drawings form a part of this application and are used together with the embodiments of the present invention to explain the principles of the present invention, rather than to limit the scope of the present invention.

[0019] As Figure 1As shown in the figure, blasting is carried out on the ice surface, an opening can be formed inside the ice layer M1, and the opening is filled with broken ice M2. The broken ice M2 is in a spider web shape. The floating ice clearing device for ice layer explosion opening in the embodiment of the present invention is used to clear large broken ice M2 to facilitate the subsequent placement of underwater equipment. Of course, this ice clearing device can also be applied to the cleaning work of large floating ice on the water surface in other fields.

[0020] As Figures 2-5 shown in the figure, a floating ice clearing device for ice layer explosion opening provided by the present invention includes a frame 100, a force arm assembly 200 and an ice grasping assembly 300. The force arm assembly 200 includes a side plate 210 and a telescopic member 220. The bottom end of the side plate 210 is hinged to the side wall of the frame 100. The telescopic member 220 is arranged above the side plate 210 and is hinged to the frame 100. The output end of the telescopic member 220 is slidably and hinged to the side plate 210. The telescopic member 220 is used to drive the side plate 210 to rotate relative to the frame 100. The ice grasping assembly 300 includes a slider 310, a spike 320 and a driving member 330. The slider 310 is slidably connected to the side plate 210 along the length direction of the side plate 210. The spike 320 is connected to the side of the slider 310 away from the telescopic member 220. The driving member 330 is installed on the side plate 210, and the output end of the driving member 330 is connected to the slider 310 for driving the slider 310 to slide.

[0021] During implementation, after the ice surface explodes to form an opening, the ice clearing device can be placed into the opening. As the device floats on the water surface and moves to a position close to the large broken ice M2, the telescopic member 220 drives the vertically arranged side plate 210 to move horizontally. The spike 320 on the slider 310 is driven into the large broken ice M2. The frame 100 drives the large broken ice M2 to move to a position close to the ice layer M1. The telescopic member 220 drives the side plate 210 to rotate, so that the side of the side plate 210 close to the ice layer M1 is tilted up until the tilted side of the broken ice is higher than the ice layer M1. The driving member 330 drives the slider 310 to move until the grasped large broken ice M2 is moved onto the ice layer M1, thus completing the cleaning work of the large broken ice M2.

[0022] The frame 100 in this implementation scheme is used to bear the force arm assembly 200 and the ice grasping assembly 300. The frame 100 should have a certain impact resistance, and at the same time its own buoyancy can make it float on the ice surface. The frame 100 can also move on the water surface so that it can move along the direction close to the large broken ice M2 or drive the large broken ice M2 it grasps to move.

[0023] In one embodiment, the frame 100 includes a fuselage 110, a cone 120, and a buoyancy body 130. The fuselage 110 is cylindrical. The top of the cone 120 is fixedly connected to the bottom of the fuselage 110, and the bottom of the cone 120 forms a tip. The buoyancy body 130 is installed on the side wall of the fuselage 110. Both the side plate 210 and the telescopic member 220 are hinged to the fuselage 110.

[0024] Among them, the interior of the fuselage 110 can adopt a hollow structure, and structures such as a power supply and a controller can be installed therein to control the actions of the force arm assembly 200 and the ice grasping assembly 300. It can be understood that the connection between the power supply and the controller and the force arm assembly 200 and the ice grasping assembly 300 is a connection method that can be thought of by those skilled in the art and is not the focus of the embodiments of the present application. It does not affect the implementation in the embodiments of the present application. Therefore, no further elaboration and description will be made.

[0025] At the same time, the interior of the fuselage 110 can also be filled with buoyancy materials to increase its own buoyancy. The cone 120 should have a high impact resistance. During the process of deploying the ice clearing device, by making the diameter of the cone 120 larger than the width of the force arm assembly 200 in the retracted state, the force arm assembly 200 can be effectively protected from impact. The cone 120 can also break large ice fragments M2 located below it.

[0026] Among them, the buoyancy body 130 can be realized by structures such as foam, which is a structure that can be thought of by those skilled in the art, and no further elaboration and description will be made here.

[0027] To enable the frame 100 to move on the water surface, in one embodiment, the frame 100 further includes a power member 140. The power member 140 is installed on the side wall of the fuselage 110 and is disposed at a position between the buoyancy body 130 and the cone 120. The vertical distance from the buoyancy body 130 to the fuselage 110 is less than the radius of the cone 120 and the radius of the buoyancy body 130.

[0028] Among them, the power member 140 can adopt multiple turbines installed on the circumferential side of the fuselage 110. By controlling the actions of different turbines, the fuselage 110 can be driven to travel in different directions. It can be understood that the turbine is a power structure of a vehicle that can be thought of by those skilled in the art, and no further elaboration and description will be made here.

[0029] At the same time, by controlling the actions of different turbines, it is also possible to avoid the entire device from tilting during the ice clearing process due to connecting to large ice fragments M2, that is, multiple worm wheels can control the tilting angle of the entire device.

[0030] The arm component 200 in this embodiment includes a side plate 210 and a telescopic member 220. The bottom end of the side plate 210 is hinged to the side wall of the frame 100. The telescopic member 220 is arranged above the side plate 210 and hinged to the frame 100. The output end of the telescopic member 220 is slidably and hingedly connected to the side plate 210. The telescopic member 220 is used to drive the side plate 210 to rotate relative to the frame 100.

[0031] Among them, the telescopic member 220 can be implemented by a telescopic oil cylinder. The output end of the telescopic oil cylinder is connected to a hinge seat, and the hinge seat is slidably connected to a chute 221 opened on the side plate 210. When the telescopic oil cylinder contracts, the side plate 210 rotates towards the direction close to the fuselage 110. When the telescopic oil cylinder extends, the side plate 210 rotates towards the direction away from the fuselage 110. Therefore, by controlling the oil intake and oil return of the telescopic oil cylinder, the side plate 210 can be driven to rotate.

[0032] In one embodiment, the side plate 210 is hinged to the middle part of the frame 100, and the telescopic member 220 is hinged to the side wall at the top of the fuselage 110.

[0033] After grasping the large broken ice M2, in order to reduce the pressure exerted by the large broken ice M2 on the ice cleaning device, in one embodiment, the device further includes floating plates 230 installed on both sides of the side plate 210. By providing the floating plates 230, the buoyancy of the side plate 210 can be increased.

[0034] In one embodiment, the number of the arm components 200 is multiple, and the multiple arm components 200 are evenly arranged along the circumferential direction of the frame 100 to improve the ice cleaning efficiency.

[0035] The ice grasping component 300 in this embodiment includes a slider 310, a spike 320, and a driving member 330. The slider 310 is slidably connected to the side plate 210 along the length direction of the side plate 210. The spike 320 is connected to the side of the slider 310 away from the telescopic member 220. The driving member 330 is installed on the side plate 210, and the output end of the driving member 330 is connected to the slider 310 for driving the slider 310 to slide.

[0036] To improve the grasping probability of the large broken ice M2, that is, the probability that the spike 320 penetrates into the large broken ice M2, and reduce the number of times of reciprocally driving the side plate 210, in one embodiment, the number of the sliders 310 is multiple, the multiple sliders 310 are arranged in sequence along the length direction of the side plate 210, and multiple spikes 320 are installed on each slider 310.

[0037] As Figure 6 shown, to facilitate driving the slider 310 to slide, in one embodiment, the driving member 330 includes a conveyor belt installed on the side plate 210 and a support sliding plate 331. One side of the slider 310 is fixedly connected to the conveyor belt, and the other side of the slider 310 is slidably connected to the support sliding plate 331.

[0038] Among them, to prevent the conveyor belt from deforming and causing the slider 310 to be unable to slide, the above conveyor belt can adopt a plate chain conveyor belt.

[0039] To facilitate the separation of the ice cube from the spike 320, in one embodiment, the ice grasping assembly 300 further includes a lifting member 340 installed on the slider 310. The spike 320 is slidably connected to the slider 310 along its length direction, and the output end of the lifting member 340 is connected to the top end of the spike 320 for driving the spike 320 to slide.

[0040] Among them, the ice grasping assembly 300 further includes a limiting plate 350 fixedly connected to the side plate 210. The limiting plate 350 is arranged on the side of the side plate 210 away from the telescopic member 220 and is arranged parallel to the side plate 210. The spike 320 passes through a strip-shaped through groove formed in the limiting plate 350.

[0041] Working process: 1) As Figure 1 shown, after blasting, there are many large broken ice blocks M2 at the explosion opening of the ice layer M1. Ice clearing devices can be dropped through devices such as drones. The cone 120 can contact the broken ice on the water surface to perform the ice breaking function, enabling the ice clearing device to successfully fall into the water, avoiding the impact damage of the broken ice on the force arm assembly 200 and the ice grasping assembly 300. Under the buoyancy force, the ice clearing device floats on the water surface. At this time, the ice clearing device is in a retracted state, as Figure 2 shown in.

[0042] 2) Figures 3-4 This is the deployment schematic diagram of the device. During the process of the device changing from the retracted state to the deployed state, the telescopic oil cylinder drives the side plate 210 to rotate from the vertical state to the horizontal state at a certain speed, and the spike 320 is nailed into the large broken ice block M2 to be cleaned, as Figure 7 shown in; 3) As Figure 6 and Figure 8 shown, the large broken ice block M2 grabbed can be driven by the turbine to move to a position close to the ice layer M1, and the angle of the side plate 210 is adjusted by the telescopic oil cylinder to tilt the large broken ice block M2, that is, the side of the large broken ice block M2 close to the ice layer M1 is lifted.

[0043] 4) As Figure 8 shown, the conveyor belt drives the slider 310 and the spike 320 to move along the direction close to the ice layer M1, so that the large broken ice block M2 moves onto the ice layer M1; 5) As Figure 9As shown, the driving member 330 drives the nail 320 to move away from the large ice fragment M2. Blocked by the limiting plate 350, the nail 320 separates from the large ice fragment M2, and the large ice fragment M2 falls onto the ice layer M1, thus completing the cleaning process of the large ice fragment M2.

[0044] Compared with the prior art: After an opening is formed by ice surface explosion, the ice cleaning device can be placed into the opening. As the device floats on the water surface and moves to a position close to the large ice fragment M2, the telescopic member 220 drives the vertically arranged side plate 210 to move horizontally. The nail 320 on the slider 310 is nailed into the large ice fragment M2. The frame 100 drives the large ice fragment M2 to move to a position close to the ice layer M1. The telescopic member 220 drives the side plate 210 to rotate, so that the side of the side plate 210 close to the ice layer M1 tilts up until the tilted side of the ice fragment is higher than the ice layer M1. The driving member 330 drives the slider 310 to move until the grasped large ice fragment M2 is moved to be located on the ice layer M1, thus completing the cleaning work of the large ice fragment M2.

[0045] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered within the protection scope of the present invention.
