Description

Technical Field

[0001] The present invention relates to the technical field of boats, in particular to polar working boats and ice-covered ships. Background Art

[0002] Because both the Antarctic and the Arctic are largely covered in ice, existing ice-faring vessels are mostly a combination of research vessels and icebreakers. This results in large tonnage, deep draft, and an inability to reach shallower waters. To address this problem, the conventional approach is to anchor the vessel in a specific area, with crew members carrying their equipment in a workboat to the vicinity of the ice. If the ice is close to their desired destination, they walk to the designated location. If the ice is far from their desired destination, they use a helicopter. Consequently, workboats have become an essential piece of equipment for polar personnel.

[0003] The existing workboats are of two types. One is to set a soft air bag around the workboat, and use a fan to fill air into the bottom to form an air cushion, which can effectively reduce the movement resistance of the workboat and increase the speed of the workboat. However, the bottom of the workboat, the air bag and the sailing surface will form a relatively closed air cavity, which causes the compressed air to escape to the surroundings after being ejected, splashing a large amount of water, making the energy consumption of the workboat high; the other is to set a retractable embedded air bag at the bottom of the workboat. When the pressure in the air bag reaches a certain value, the hull is supported by the air cushion, and the air cushion makes the hull leave the water surface, greatly reducing the resistance and increasing the speed of the workboat. However, the speed of this workboat is still relatively low, and the structure of this workboat is complex and the number of parts is large, resulting in a large size and heavy weight of the workboat, high operating energy consumption of the workboat, and the energy consumption of the workboat will be further increased in the process of repeatedly retracting and deploying the air bag, resulting in poor performance of the workboat. Summary of the Invention

[0004] The purpose of the present invention is to provide a polar work boat and an ice-covered vessel to solve the problems of high energy consumption and poor performance of work boats in the prior art.

[0040] Figure 1 and Figure 2 The ab direction is the width direction of the workboat body 1; Figure 2 and Figure 5 The cd direction is the height direction of the workboat body 1; Figure 1 、 Figure 4 and Figure 5 The ef direction is the length direction of the workboat body 1.

[0041] The present invention provides a polar working boat, such as Figure 1-3As shown, the polar workboat includes a workboat body 1 and an airbag structure. The airbag structure includes an airbag inflation assembly 3 and two cushion airbag groups 2. The two cushion airbag groups 2 are spaced apart on both sides of the workboat body 1 along the width direction. The cushion airbag group 2 includes a first fixed airbag 21 and a first adjustment airbag 22 spaced apart along the height direction of the workboat body 1. The first fixed airbag 21 is fixedly arranged on the workboat body 1 and is distributed above the first adjustment airbag 22. The first adjustment airbag 22 is fixedly arranged on the first fixed airbag 21. The airbag inflation assembly 3 can inflate the first fixed airbag 21 and the first adjustment airbag 22. Specifically, the first fixed airbag 21 is always in an inflated state, and air can be added to the first fixed airbag 21 through the airbag inflation component 3. The inflation amount of the first regulating airbag 22 can be adjusted according to actual navigation needs, so that the draft depth of the polar work boat can be adjusted, thereby effectively improving the navigation speed of the polar work boat. Compared with the existing technology, the polar work boat has a simple structure, small size, and light weight. It can effectively reduce energy consumption while increasing the navigation speed, thereby improving the performance of the polar work boat.

[0042] Among them, along the length direction of the workboat, such as Figure 1-3 As shown, the cross-sectional area of ​​the first fixed airbag 21 is larger than that of the first regulating airbag 22. It is understood that even when the first regulating airbag 22 is slightly inflated, the first fixed airbag 21 can still provide a relatively large basic buoyancy to the polar workboat, thereby further improving the performance of the polar workboat.

[0043] Specifically, in this embodiment, Figure 2 As shown, along the length of the workboat body 1, the first fixed airbag 21 has a roughly circular cross-section, as does the first regulating airbag 22. This gives the lifting airbag assembly 2 a roughly gourd-shaped cross-section. This arrangement reduces the contact area between the lifting airbag assembly 2 and the navigation surface, thereby enabling better control of the polar workboat's navigation speed. Specifically, the navigation surface refers to the sea or land surface.

[0044] Preferably, if Figure 3 As shown, the first fixed airbag 21 includes multiple first sub-cavities 211, which are spaced apart along the length of the workboat body 1. The first fixed airbag 21 is also equipped with multiple first inflation valves 212, which are arranged in a one-to-one correspondence with and communicate with the multiple first sub-cavities 211. This arrangement improves the efficiency of inflating the first fixed airbag 21. Specifically, in this embodiment, the first fixed airbag 21 is provided with five first sub-cavities 211 as an example.

[0045] Specifically, if Figure 3As shown, the airbag inflation assembly 3 includes an inflation fan 31, a control valve 32, and a quick-charge connector 33. The inflation fan 31 is connected to the control valve 32. The output end of the control valve 32 can be connected to the first fixed airbag 21 through the quick-charge connector 33, and the output end of the control valve 32 can be connected to the first regulating airbag 22 through the quick-charge connector 33. Specifically, the output end of the control valve 32 can be connected to the first inflation valve 212 through the quick-charge connector 33; the first regulating airbag 22 is provided with a second inflation valve 221, and the output end of the control valve 32 can be connected to the second inflation valve 221 through the quick-charge connector 33. In this way, the first fixed airbag 21 and the first regulating airbag 22 can be inflated. Optionally, a pressure gauge 34, a dryer 35, and a filter 36 are provided on the pipeline connecting the inflation fan 31 and the control valve 32. The pressure gauge 34 can detect the pressure of the gas output by the inflation fan 31 , the dryer 35 can dry the gas output by the inflation fan 31 , and the filter 36 can filter the gas output by the inflation fan 31 .

[0046] Among them, such as Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, the polar workboat also includes a head air seal structure, a tail air seal structure and a cushioning and inflating assembly arranged on the workboat body 1. The head air seal structure is distributed at the front end of the workboat body 1 along the length direction, and the tail air seal structure is distributed at the rear end of the workboat body 1 along the length direction. The head air seal structure can extend along the height direction of the workboat body 1 or be accommodated at the bottom of the workboat body 1, so that the two cushioning airbag groups 2, the head air seal structure, the tail air seal structure, the outer wall of the workboat body 1 and the navigation surface can form a cushioning air cavity; the cushioning and inflating assembly can inflate the cushioning air cavity and can inflate the tail air seal structure. Specifically, when it is necessary to further adjust the draft of the polar work boat, the extension amount of the first air seal structure out of the bottom of the work boat body 1 is adjusted according to the actual working conditions, the cushioning and inflating assembly is controlled to inflate the tail air seal structure, and the airbag inflating assembly 3 is controlled to further inflate the first regulating airbag 22, so that the two cushioning airbag groups 2, the first air seal structure, the tail air seal structure, the outer wall of the work boat body 1 and the navigation surface are surrounded to form a cushioning air cavity. It can be understood that there is no connection between the two cushioning airbag groups 2 and the first air seal structure and the tail air seal structure, so the two cushioning airbag groups 2 There are gaps between the front air seal structure and the tail air seal structure, so that the cushion air cavity is not completely closed. With this arrangement, when the cushion inflation component is controlled to inflate the cushion air cavity, it can effectively avoid the phenomenon in the prior art that the gas filled in the air cavity escapes to the surroundings and causes a large amount of water splashing, and can further adjust the draft depth of the polar work boat, thereby further reducing the navigation resistance of the polar work boat and improving the navigation speed of the polar work boat. Specifically, when the cushion inflation component is not working, the front air seal structure is accommodated at the bottom of the work boat body 1, and the tail air seal structure is deflated.

[0047] Specifically, if Figure 1 、 Figure 2 and Figure 4 As shown, the forward air seal structure includes a second drive mechanism and an air seal plate 4. The air seal plate 4 is rotatably connected to the workboat body 1. The second drive mechanism can drive the air seal plate 4 to rotate around the connection between the air seal plate 4 and the workboat body 1. This arrangement allows the air seal plate 4 to extend and form a lifting air cavity with the lifting airbag assembly 2, the rear air seal structure, the outer wall of the workboat body 1, and the navigation surface.

[0048] More specifically, in this embodiment, Figure 1 、 Figure 2 and Figure 4 As shown, the second drive mechanism includes a drive member fixedly mounted on the workboat body 1. Along the travel direction of the workboat body 1, the first end of the airtight plate 4 is rotatably connected to the workboat body 1, and the second end is movably connected to the output end of the drive member. The first end of the airtight plate 4 is located forward of the second end, and the travel direction of the workboat body 1 is parallel to the length of the workboat body 1. Preferably, along the length of the workboat body 1, the shape of the airtight plate 4 generally aligns with the streamlined shape of the hull bottom. This arrangement can reduce the travel resistance of the workboat body 1.

[0049] Specifically, if Figure 1 、 Figure 2 and Figure 5 As shown, the tail gas seal structure includes an air inlet connector and a bag-shaped inflatable apron 5 connected to the air inlet connector; the cushioning and inflating assembly includes a cushioning fan 6, and the air inlet connector is arranged at the exhaust port of the cushioning fan 6 and connected to the exhaust port of the cushioning fan 6, and the exhaust port of the cushioning fan 6 is also connected to the cushioning air cavity. With this arrangement, when it is necessary to further adjust the draft of the polar workboat, the cushioning fan 6 sends air to the exhaust port, and part of the delivered gas is filled into the bag-shaped inflatable apron 5 through the air inlet connector, and the other part is filled into the cushioning air cavity. The gas filled into the cushioning air cavity, the two cushioning airbag groups 2, and the tail gas seal structure work together to further adjust the draft of the polar workboat.

[0050] Among them, such as Figure 1 and Figure 5As shown, the polar work boat also includes a first drive mechanism 7, which includes a drive motor 71 fixedly arranged on the work boat body 1, and an air propeller 72 rotatably arranged on the work boat body 1. The output shaft of the drive motor 71 is transmission-connected to the air propeller 72 and can be connected to or separated from the input shaft of the lift fan 6. It can be understood that the air propeller 72 and the cushion lift fan 6 are synchronously driven to operate by a drive motor 71. Specifically, the work boat body 1 is also fixedly provided with a fairing 12, and the air propeller 72 is distributed in the fairing 12. When the polar work boat runs at low speed, the output shaft of the drive motor 71 drives the air propeller 72 to rotate, thereby driving the polar work boat to run at low speed. At this time, the output shaft of the drive motor 71 is separated from the input shaft of the cushion lift fan 6; when the polar work boat runs at high speed, the output shaft of the drive motor 71 drives the air propeller 72 to rotate, and synchronously drives the input shaft of the cushion lift fan 6 to rotate, thereby driving the air propeller 72 and the cushion lift fan 6 to run at the same time, so that the polar work boat can run at high speed. This arrangement reduces the number of components, saves space, and can fully utilize the driving force of the drive motor 71, effectively improving the performance of the polar work boat.

[0051] Specifically, the first driving mechanism 7 further includes a connecting and disconnecting mechanism, which can connect or disconnect the output shaft of the driving motor 71 and the input shaft of the cushioning fan 6. Preferably, the connecting and disconnecting structure is a clutch.

[0052] Preferably, if Figure 1 and Figure 5 As shown, there are two cushioning fans 6 and two exhaust gas sealing structures. The two cushioning fans 6 and the two exhaust gas sealing structures are arranged in a one-to-one correspondence. The two exhaust gas sealing structures are spaced apart along the width direction of the workboat body 1 and are distributed between the two cushioning airbag groups 2. Specifically, the two cushioning fans 6 and the two bag-shaped inflatable aprons 5 are arranged in a one-to-one correspondence. The two bag-shaped inflatable aprons 5 are spaced apart along the width direction of the workboat body 1 and are distributed between the two cushioning airbag groups 2. Such an arrangement can improve the efficiency of the cushioning air cavity formed by the cushioning airbag group 2, the air sealing plate 4, the bag-shaped inflatable apron 5, the outer wall of the workboat body 1 and the navigation surface, and can also further improve the effect of adjusting the draft depth of the polar workboat, thereby further reducing the energy consumption of driving the polar workboat forward on the basis of improving the navigation speed.

[0053] Preferably, in order to improve the stability of the polar work boat, Figure 1-3As shown, the airbag structure also includes a stabilizing airbag group 8 fixedly mounted on the bottom of the workboat body 1. Along the width of the workboat body 1, the stabilizing airbag group 8 is located between the two lifting airbag groups 2. Along the length of the workboat body 1, the stabilizing airbag group 8 is located between the forward and aft air seal structures. It will be understood that the lifting air chamber is divided into two first sub-cavities 211, and the two lifting fans 6 are provided in a one-to-one correspondence with the two first sub-cavities 211.

[0054] Specifically, if Figure 1-3 As shown, the stabilizing airbag group 8 includes a second fixed airbag 81 and a second regulating airbag 82 spaced apart along the height direction of the workboat body 1. The second fixed airbag 81 is fixedly arranged at the bottom of the workboat body 1 and distributed above the second regulating airbag 82. The second regulating airbag 82 is fixedly arranged at the second fixed airbag 81. The airbag inflation assembly 3 can also inflate the second fixed airbag 81 and the second regulating airbag 82. Specifically, the second fixed airbag 81 is always in a state of being filled with air, and air can be added to the second fixed airbag 81 through the airbag inflation assembly 3. The inflation volume of the second regulating airbag 82 can be adaptively adjusted based on the inflation volume of the first regulating airbag 22, so that the bottom of the second regulating airbag 82 and the bottoms of the two first regulating airbags 22 are on the same horizontal plane along the height direction of the workboat body 1, thereby effectively improving the stability of the polar workboat.

[0055] Specifically, if Figure 2 and Figure 3 As shown, the second fixed airbag 81 is provided with a third inflation valve 811, and the output end of the control valve 32 can be connected to the third inflation valve 811 via the quick-charge connector 33. The second regulating airbag 82 is provided with a fourth inflation valve 821, and the output end of the control valve 32 can be connected to the fourth inflation valve 821 via the quick-charge connector 33. This allows the second fixed airbag 81 and the second regulating airbag 82 to be inflated.

[0056] More specifically, Figure 2 and Figure 3 As shown, along the length of the workboat body 1, the cross-sectional area of ​​the second fixing airbag 81 is larger than that of the second regulating airbag 82. Along the length of the workboat body 1, the second fixing airbag 81 and the regulating airbag 82 are roughly circular in cross-section, giving the stabilizing airbag assembly 8 a roughly gourd-shaped cross-section. This arrangement reduces the contact area between the stabilizing airbag assembly 8 and the navigation surface, thereby enabling better control of the polar workboat's navigation speed.

[0057] Among them, such as Figure 1As shown, along the length direction of the workboat body 1, a rudder 11 is further provided at the tail of the workboat body 1. The direction of travel of the polar workboat can be controlled by the rudder 11. In this embodiment, three rudders 11 are provided as an example.

[0058] The specific structure of the workboat body 1 is prior art and will not be described in detail here. The specific structure of the transmission connection between the drive motor 71 and the air propeller 72, as well as the specific structure of the transmission connection between the drive motor 71 and the cushion lift fan 6, are prior art and will not be described in detail here.

[0059] The present invention also provides an ice-going vessel comprising the aforementioned polar workboat, wherein the workboat body 1 of the polar workboat is detachably mounted on the deck of the ice-going vessel. The polar workboat can effectively reduce energy consumption while increasing the speed of the polar workboat. Equipping an ice-going vessel with the polar workboat can improve the vessel's operating performance.

[0060] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments of the present invention. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here.
