Description

Technical Field

[0001] This invention relates to the field of water surface ice surface maintenance vessel technology, specifically a multi-functional operation and maintenance vessel for water surface ice surfaces. Background Technology

[0002] Existing amphibious equipment generally uses electric, hydraulic, or pneumatic mode switching mechanisms, relying on manual operation or electronic control systems to switch between ice and water travel modes. These switching mechanisms are complex in structure and are prone to short circuits, hydraulic leaks, and component jamming in harsh conditions such as low temperature, humidity, and abundant aquatic plants. At the same time, mode switching requires shutdown, which is time-consuming and seriously disrupts the operation process, failing to meet the needs of continuous operation in water-ice alternation scenarios.

[0003] Although some equipment attempts to achieve automatic switching, they mostly rely on electronic control and synchronization control units, which are easily interfered with in complex electromagnetic environments in the field. Their actions are not synchronized, and problems such as asynchronous deployment and retraction of parts and inaccurate positioning may occur, or even transmission sway may occur. In addition, existing amphibious repair vessels have limited functions. When operating on the water, the propeller is easily interrupted due to water plants getting tangled, and it is easy to get stuck or capsize when rushing from the water surface onto the ice surface. Operational safety and environmental adaptability are difficult to guarantee. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-functional maintenance and repair vessel for water and ice surfaces to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-functional maintenance and repair vessel for both water and ice surfaces, comprising: a floating structure, a first water-ice switching device, and a second water-ice switching device; the floating structure is used to float on the water surface; the first water-ice switching device is disposed within the floating structure; the bottom of the first water-ice switching device is in contact with the ice surface; the second water-ice switching device is disposed within the floating structure, and the second water-ice switching device is connected to the first water-ice switching device in a transmission manner. When the floating structure is launched into the water and its bottom is not lifted or supported by the ice surface, the weight of the water surface mode components of the second and first water-ice switching devices can be used as the switching power source to drive the second and first water-ice switching devices to retract the ice surface travel mode components, thereby switching to deploying the water surface mode travel components.

[0006] Preferably, the first water-ice switching device includes: a first switching component, a weed removal component, and a first ice surface traveling component; the first switching component is disposed within the floating structure, and the two movable output ends of the first switching component can expand or contract relative to each other; the weed removal component is disposed at one movable output end of the first switching component, and the bottom of the weed removal component is in contact with the ice surface; the first ice surface traveling component is disposed at the other movable output end of the weed removal component, and the bottom of the first ice surface traveling component is in contact with the ice surface. The movable end of the weed removal component is heavier than the movable end of the first ice surface traveling component. When the weed removal component is submerged in water and its bottom is not lifted or supported by the ice surface, the weight of the movable end of the weed removal component, in conjunction with the first switching component, allows it to retract and switch to water surface mode. By utilizing the weight difference between the weed removal component and the first ice surface traveling component, and in conjunction with the first switching component, the mode of the first water-ice switching device is automatically switched.

[0007] Preferably, the second water-ice switching device includes: a second switching component, a water surface traveling component, and a second ice surface traveling component; the second switching component is disposed within the floating structure, and its two movable output ends can expand or contract relative to each other; the water surface traveling component is disposed at one movable output end of the second switching component, its bottom contacting the ice surface, and its input end being drively connected to the weed removal component; the second ice surface traveling component is disposed at the other movable output end of the second switching component, and the second ice surface traveling component... The bottom end of the component contacts the ice surface. The moving end of the water surface traveling component is heavier than the moving end of the second ice surface traveling component. When the weed removal component is submerged in water, and its bottom is not lifted or supported by the ice surface, the weight of the moving end of the water surface traveling component, in conjunction with the second switching component, retracts the second ice surface traveling component and switches the water surface traveling component. Thus, the water surface traveling component and the weed removal component are synchronized to the water surface mode. By driving the second water-ice switching device to the first water-ice switching device, the weight difference between the water surface traveling component and the second ice surface traveling component is used to perform synchronous mode switching of the two sets of switching devices.

[0008] Preferably, the floating structure includes: a manned hull, an outer shell, and floating airbags; the manned hull is used to carry people and float on the water surface; the outer shell is disposed on the bottom surface of the manned hull, a through rectangular groove is opened on the left side of the outer wall of the outer shell, a through first U-shaped groove is opened on the right side of the outer wall, and four symmetrical second U-shaped grooves are opened on the front and rear sides of the outer wall of the outer shell, the rectangular groove, the first U-shaped groove and the four second U-shaped grooves all extending into the outer shell; there are two floating airbags, which are symmetrically arranged on the front and rear sides of the outer wall of the outer shell, and the two floating airbags are used to assist in floating on the water surface. By opening multiple grooves in the outer shell and cooperating with the floating airbags, the stability of the hull's floating is enhanced, while providing limiting and operating space for subsequent switching components.

[0009] Preferably, the first switching component includes: a first limiting recess, a first rack, a first support plate, and a first gear; there are four first limiting recesses, symmetrically arranged on the inner wall surface of the housing; there are two first racks, movably and symmetrically sleeved within the four first limiting recesses; the first support plate is disposed on the inner wall surface of the housing; the first gear is disposed on the outer wall of the first support plate via a first bearing, and each of the first gears meshes with the two first racks. When the first gear rotates, it can drive the two first racks to expand or contract relative to each other. By meshing the first gear with the two first racks, it cooperates with the first limiting recesses to limit and guide, and drives the synchronous expansion or contraction of the two movable output ends.

[0010] Preferably, the weed removal assembly includes: a first connecting rod, an L-shaped transmission rod, a guide triangle plate, a pulley, a first L-shaped connecting rod, a second L-shaped connecting rod, and a weed cutter; one end of the first connecting rod is disposed on the outer wall of a first rack; one end of the L-shaped transmission rod is disposed on the other end of the first connecting rod; the guide triangle plate is disposed on the bottom surface of the L-shaped transmission rod; the pulley is disposed on the other end of the guide triangle plate, and the pulley is in contact with the ice surface, with the ice surface lifting and supporting the pulley; one end of the first L-shaped connecting rod is disposed on the outer wall of a first rack; one end of the second L-shaped connecting rod is disposed on the other end of the first L-shaped connecting rod, and the other end of the second L-shaped connecting rod is movably sleeved in a rectangular groove; the weed cutter is disposed on the other end of the second L-shaped connecting rod, and the mutual cooperation of the guide triangle plate, the pulley, and the weed cutter allows for switching between ice surface support guidance and water surface weed removal.

[0011] Preferably, the first ice surface traveling component includes: a third L-shaped connecting rod, a first transmission rod, and a first ice surface electric double spike wheel; one end of the third L-shaped connecting rod is disposed on the outer wall of another first rack; one end of the first transmission rod is disposed on the other end of the third L-shaped connecting rod; the first ice surface electric double spike wheel is disposed on the other end of the first transmission rod, and the guide triangle plate is in contact with the ice surface; the aquatic plant cutter is heavier than the first ice surface electric double spike wheel. When the pulley is in the water and is not lifted or supported by the ice surface, the weight of the aquatic plant cutter drives the second L-shaped connecting rod to move to the bottom of the rectangular groove for limiting, and at the same time drives one first rack to rotate the first gear, and drives another first rack to move the first ice surface electric double spike wheel upward to retract into one of the two second U-shaped grooves, and switches the aquatic plant cutter into the water surface mode. By making the weight of the aquatic plant cutter heavier than the first ice surface electric double spike wheel, and using gravity drive, the retraction of the first ice surface electric double spike wheel and the limiting of the aquatic plant cutter are switched.

[0012] Preferably, the second switching component includes: a second limiting recess, a second rack, a second support plate, and a second gear; there are four second limiting recesses, symmetrically arranged on the inner wall surface of the housing; there are two second racks, movably and symmetrically sleeved within the four second limiting recesses; the second support plate is disposed on the inner wall surface of the housing; the second gear is disposed on the outer wall of the second support plate via a first bearing, and each second gear meshes with the two second racks. When the second gear rotates, it can drive the two second racks to expand or contract relative to each other. By meshing the second gear with the two second racks, and cooperating with the guidance of the second limiting recesses, the synchronous reverse expansion or contraction movement of the two moving output ends of the second switching component is realized.

[0013] Preferably, the water surface propulsion component includes: a second connecting rod, a long rod, a fourth L-shaped connecting rod, and an underwater electric propeller; one end of the second connecting rod is disposed on the outer wall of a second rack; one end of the long rod is disposed on the other end of the second connecting rod, and the other end of the long rod is fixedly connected to the outer wall of the L-shaped transmission rod; one end of the fourth L-shaped connecting rod is disposed on the outer wall of a second rack; the underwater electric propeller is disposed on the other end of the fourth L-shaped connecting rod. By fixing the long rod to the L-shaped transmission rod, the water surface propulsion component and the weed removal component are synchronized and linked, ensuring consistent mode switching.

[0014] Preferably, the second ice-surface traveling assembly includes: a fifth L-shaped connecting rod, a second transmission rod, and a second electric double-pronged ice-surface wheel; one end of the fifth L-shaped connecting rod is disposed on the outer wall of another second rack; one end of the second transmission rod is disposed on the other end of the fifth L-shaped connecting rod; the second electric double-pronged ice-surface wheel is disposed on the other end of the second transmission rod, and the second electric double-pronged ice-surface wheel is in contact with the ice surface; the underwater electric propeller is heavier than the second electric double-pronged ice-surface wheel, and when the pulley is submerged and not lifted or supported by the ice surface, it travels through the long rod and the L-shaped connecting rod... The connection of the transmission rod and the weight of the underwater electric propeller itself enable the underwater electric propeller to move to the bottom of the first U-shaped groove for a limit position. At the same time, it drives a second rack to rotate the second gear, causing another second rack to move the second ice surface electric double spike wheel upward to the other two second U-shaped grooves for retraction. It also switches the underwater electric propeller into surface mode. Since the weight of the underwater electric propeller is greater than that of the second ice surface electric double spike wheel, gravity drives the second ice surface electric double spike wheel to retract and switch the limit position of the underwater electric propeller.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. Traditional amphibious equipment relies on external power sources such as electric, hydraulic, and pneumatic power for switching between water and ice surfaces. This maintenance vessel uses the weight of its surface mode components as the power source for switching between ice and water surfaces, and the lifting force of the ice surface as the power source for switching between water and ice surfaces. It can automatically complete the mode switching without manual intervention or additional electrical control systems. This prevents the complex power switching mechanism from easily failing under harsh conditions such as low temperature, humidity, and abundant aquatic plants. The mode switching process is completed synchronously with the maintenance vessel's operating condition change, without the need for shutdown operations. This solves the problems of long switching time and work interruption of existing equipment, and improves the continuity of operations in water-ice alternation scenarios.

[0016] 2. Both the first and second switching components adopt a reverse transmission structure of single gear and double rack, which can drive the corresponding two sets of components to move synchronously in opposite directions. This ensures that the water surface mode component unfolds while the ice surface mode component automatically retracts, resulting in high synchronization. The rectangular groove, the first U-shaped groove, and the second U-shaped groove on the outer shell provide precise guidance and limit for each moving component, avoiding swaying and tooth slippage during transmission and ensuring that each component is in the accurate working position after mode switching. No additional synchronization control unit is required. The stability of the mechanical linkage structure is higher than that of the electronic control synchronization system, making it suitable for complex field operation environments. At the same time, no manual intervention or external power drive is required. It can automatically complete the switching of travel modes with the natural transition between water surface and ice surface conditions.

[0017] 3. In surface mode, the weed cutter automatically extends to the working position as the mode is switched, allowing for simultaneous weed removal on the surface while the repair vessel is moving. This prevents weeds from tangling with the underwater electric propeller, avoiding propeller damage or power interruption, and improving the safety of surface operations. In ice mode, the first and second electric double-barreled wheels extend automatically and synchronously. The double-barreled structure enhances grip and anti-slip performance on ice, ensuring stable movement of the repair vessel on smooth ice. The combination of the guide triangle and pulley design allows the repair vessel to smoothly transition from the surface to the edge of the ice, avoiding the risk of the vessel getting stuck or capsizing, and improving the safety of cross-condition operations.

[0020] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0021] Please see Figures 1-8This invention provides a technical solution for a multi-functional maintenance and repair vessel for both water and ice surfaces, comprising: a floating structure 1, a first water-ice switching device 2, and a second water-ice switching device 3; the floating structure 1 is used to float on the water surface; the first water-ice switching device 2 is disposed within the floating structure 1; the bottom of the first water-ice switching device 2 is in contact with the ice surface; the second water-ice switching device 3 is disposed within the floating structure 1 and is connected to the first water-ice switching device 2 via a transmission connection. When the floating structure 1 is launched into the water and its bottom is not lifted or supported by the ice surface, the weight of the water surface mode components of the second water-ice switching device 3 and the first water-ice switching device 2 can be used as the switching power source to drive the vessel. The second water-ice switching device 3 and the first water-ice switching device 2 retract the components of the ice surface travel mode, thereby switching to the water surface travel mode components. The floating structure 1 provides stable water surface buoyancy and overall load-bearing capacity. In conjunction with the transmission linkage between the first water-ice switching device 2 and the second water-ice switching device 3, the gravity of the water surface mode components serves as the switching power source for switching from ice surface to water surface, and the lifting force of the ice surface serves as the switching power source for switching from water surface to ice surface. There is no need to add external power switching mechanisms such as electric or hydraulic systems. This enables the maintenance vessel to automatically and synchronously switch between modes under both water surface and ice surface conditions, improving the mode switching efficiency and operational continuity in water-ice alternating operation scenarios.

[0022] As a preferred option, further, such as Figure 4 and Figure 5 As shown, the first water-ice switching device 2 includes: a first switching component 21, a weed removal component 22, and a first ice surface traveling component 23; the first switching component 21 is disposed within the floating structure 1, and its two movable output ends can expand or contract relative to each other; the weed removal component 22 is disposed at one movable output end of the first switching component 21, and its bottom contacts the ice surface; the first ice surface traveling component 23 is disposed at the other movable output end of the weed removal component 22, and its bottom contacts the ice surface. The movable end of the weed removal component 22 is heavier than the movable end of the first ice surface traveling component 23. When the weed removal component 22 is submerged, its bottom is not lifted or supported by the ice surface. The weight of the moving end of the weed removal component 22, in conjunction with the retraction of the first switching component 21, switches the weed removal component 22 to the water surface mode. The first switching component 21 enables the weed removal component 22 and the first ice surface traveling component 23 to move in opposite directions. The weight difference between the moving ends of the weed removal component 22 and the first ice surface traveling component 23 serves as the switching power from ice surface to water surface, and the lifting force of the ice surface on the weed removal component 22 serves as the switching power from water surface to ice surface. This allows the first water-ice switching device 2 to switch to fully automatic mode. At the same time, the weed removal function and the ice surface traveling function enable the first water-ice switching device 2 to perform weed removal operations simultaneously in water surface mode, improving the multi-functionality and operational continuity of the maintenance vessel.

[0023] As a preferred option, further, such as Figure 6 , Figure 7 and Figure 8 As shown, the second water-ice switching device 3 includes: a second switching component 31, a water surface traveling component 32, and a second ice surface traveling component 33. The second switching component 31 is disposed within the floating structure 1, and its two movable output ends can expand or contract relative to each other. The water surface traveling component 32 is disposed at one movable output end of the second switching component 31, with its bottom in contact with the ice surface. The input end of the water surface traveling component 32 is connected to the weed removal component 22. The second ice surface traveling component 33 is disposed at the other movable output end of the second switching component 31, with its bottom in contact with the ice surface. The movable end of the water surface traveling component 32 is heavier than that of the second ice surface traveling component 33. When the weed removal component 22 is submerged, its bottom is not lifted or supported by the ice surface, and it travels through the water surface. The weight of the moving end of the inlet component 32, in conjunction with the second switching component 31, retracts the second ice surface traveling component 33 and switches the water surface traveling component 32, thereby synchronizing the water surface traveling component 32 and the weed removal component 22 to the water surface mode. Through the reverse linkage between the water surface traveling component 32 and the second ice surface traveling component 33 by the second switching component 31, and the weight difference between the moving ends of the water surface traveling component 32 and the second ice surface traveling component 33, and in conjunction with the transmission connection design between the water surface traveling component 32 and the weed removal component 22, the fully automatic synchronous mode switching of the second water-ice switching device 3 and the first water-ice switching device 2 can be achieved without the need for an additional electronic power source, ensuring consistent water-ice mode switching. At the same time, the water surface traveling component 32 provides propulsion power in the water surface mode, improving the continuity of operation and environmental adaptability of the maintenance vessel in both water surface and ice surface conditions.

The two floating airbags 16 are used to assist in floating on the water surface. The rectangular groove 13, the first U-shaped groove 14 and the four second U-shaped grooves 15 opened on the shell 12 provide guidance and operation limit for the subsequent components, so as to store and fix non-operating parts in different modes. With the auxiliary buoyancy provided by the two symmetrically arranged floating airbags 16, the maintenance vessel is prevented from floating stably and capsizing on the water surface, and the internal switching device is guaranteed to operate accurately.

[0025] As a preferred option, further, such as Figure 4 and Figure 5 As shown, the first switching assembly 21 includes: a first limiting recess 211, a first rack 212, a first support plate 213, and a first gear 214; there are four first limiting recesses 211, symmetrically arranged on the inner wall surface of the outer casing 12; there are two first racks 212, movably and symmetrically sleeved within the four first limiting recesses 211; the first support plate 213 is disposed on the inner wall surface of the outer casing 12; the first gear 214 is disposed on the outer wall of the first support plate 213 via a first bearing, and the first gear 214 meshes with the two first racks 212. When the first gear 214 rotates, it can drive the two racks 212 to rotate. The first racks 212 expand or contract with each other; four symmetrically arranged first limiting concave rods 211 provide precise limiting guidance for the two first racks 212, preventing wobble and tooth slippage during transmission; through the meshing transmission between the first gear 214 and the two first racks 212, the two first racks 212 can expand or contract synchronously in opposite directions with high synchronization; the first support plate 213 provides a stable mounting point for the first gear 214, improving the operational stability of the transmission mechanism; the whole structure uses a mechanical transmission structure, eliminating the need for additional power input and reverse force transmission, making it suitable for harsh working environments with alternating water and ice conditions.

[0026] As a preferred option, further, such as Figure 4 and Figure 5As shown, the aquatic plant removal component 22 includes: a first connecting rod 221, an L-shaped transmission rod 222, a guide triangle 223, a pulley 224, a first L-shaped connecting rod 225, a second L-shaped connecting rod 226, and an aquatic plant cutter 227; one end of the first connecting rod 221 is disposed on the outer wall of a first rack 212; one end of the L-shaped transmission rod 222 is disposed on the other end of the first connecting rod 221; the guide triangle 223 is disposed on the bottom surface of the L-shaped transmission rod 222; the pulley 224 is disposed on the other end of the guide triangle 223, and the pulley 224 is in contact with the ice surface, and the ice surface lifts and supports the pulley 224; one end of the first L-shaped connecting rod 225 is disposed on the outer wall of a first rack 212; one end of the second L-shaped connecting rod 226 is disposed on the other end of the first L-shaped connecting rod 225, and the second L-shaped connecting rod 226 is disposed on the other end of the first L-shaped connecting rod 225, and the second L-shaped connecting rod 226 is disposed on the other end of the first L-shaped connecting rod 226, and the first L-shaped connecting rod 227 is disposed on the outer wall of a first rack 212; one end of the second L-shaped connecting rod 226 is disposed on the other end of the first L-shaped connecting rod 225, and the second ...5 is disposed on the The other end of the second L-shaped connecting rod 226 is movably sleeved within the rectangular groove 13; the weed cutter 227 is located at the other end of the second L-shaped connecting rod 226; through the rigid linkage of the first connecting rod 221, the L-shaped transmission rod 222, the first L-shaped connecting rod 225, and the second L-shaped connecting rod 226, the pulley 224 and the weed cutter 227 move synchronously; through the inclined structure of the guide triangle plate 223, the repair boat can smoothly transition from the water surface to the edge of the ice surface, preventing jamming; the cooperation between the rectangular groove 13 and the second L-shaped connecting rod 226 provides the maximum limit of the guide stroke and support for the movement of the weed cutter 227; automatic switching can be completed through gravity and the force of the ice surface, and the weed removal operation function and mode switching trigger function improve the operating efficiency of the device.

[0027] As a preferred option, further, such as Figure 4 and Figure 5As shown, the first ice surface traveling component 23 includes: a third L-shaped connecting rod 231, a first transmission rod 232, and a first ice surface electric double spike wheel 233; one end of the third L-shaped connecting rod 231 is disposed on the outer wall of another first rack 212; one end of the first transmission rod 232 is disposed on the other end of the third L-shaped connecting rod 231; the first ice surface electric double spike wheel 233 is disposed on the other end of the first transmission rod 232, and the guide triangle 223 is in contact with the ice surface; the weed cutter 227 is heavier than the first ice surface electric double spike wheel 233. When the pulley 224 is in the water and is not lifted or supported by the ice surface, the weight of the weed cutter 227 drives the second L-shaped connecting rod 226 to move to the bottom of the rectangular groove 13 for limiting, and at the same time drives one first rack 212 to rotate the first gear 214, and drives the other first rack 212 to drive the first ice surface electric double spike wheel. Wheel 233 moves upward into one of the two second U-shaped grooves 15 and retracts, switching the weed cutter 227 into surface mode. Through the rigid connection between the third L-shaped connecting rod 231 and the first transmission rod 232, the first ice surface electric double spike wheel 233 and the first rack 212 are synchronously linked. Through the weight difference between the weed cutter 227 and the first ice surface electric double spike wheel 233, and in conjunction with the reverse transmission characteristics of the first gear 214, the first ice surface electric double spike wheel 233 can automatically extend and retract without additional power. The two second U-shaped grooves 15 provide storage space for the first ice surface electric double spike wheel 233, preventing additional water resistance in surface mode. The double spike structure of the first ice surface electric double spike wheel 233 improves the grip and anti-slip on the ice surface, enhancing the stability of the repair vessel's ice surface operations and the automation of the water-ice mode switching mechanism.

[0028] As a preferred option, further, such as Figure 7 and Figure 8 As shown, the second switching assembly 31 includes: a second limiting recess 311, a second rack 312, a second support plate 313, and a second gear 314; there are four second limiting recesses 311, which are symmetrically arranged on the inner wall of the outer shell 12; there are two second racks 312, which are movably and symmetrically sleeved within the four second limiting recesses 311; the second support plate 313 is arranged on the inner wall of the outer shell 12; the second gear 314 is arranged on the outer wall of the second support plate 313 through a first bearing, and the second gear 314 meshes with the two second racks 312. When the second gear 314 rotates, it can drive the two second racks 312 to expand or contract relative to each other; the second switching assembly 31 operates on the same principle as the first switching assembly 21, but the driving components are different, and the synchronous opposite expansion or contraction of the two second racks 312 is used for switching between the water surface travel assembly 32 and the ice surface travel assembly 33.

[0029] As a preferred option, further, such as Figure 6 , Figure 7 and Figure 8As shown, the surface propulsion assembly 32 includes: a second connecting rod 321, a long rod 322, a fourth L-shaped connecting rod 323, and an underwater electric propeller 324; one end of the second connecting rod 321 is disposed on the outer wall of a second rack 312; one end of the long rod 322 is disposed on the other end of the second connecting rod 321, and the other end of the long rod 322 is fixedly connected to the outer wall of the L-shaped transmission rod 222; one end of the fourth L-shaped connecting rod 323 is disposed on the outer wall of a second rack 312; the underwater electric propeller 324 is disposed on the other end of the fourth L-shaped connecting rod 323; The extended rod 322 rigidly connects the surface travel component 32 to the L-shaped transmission rod 222, enabling the second water-ice switching device 3 and the first water-ice switching device 2 to switch to fully automatic synchronous mode, ensuring that the two devices operate in unison. The rigid connection between the second connecting rod 321 and the fourth L-shaped connecting rod 323 ensures precise synchronous movement between the underwater electric propeller 324 and the second rack 312, guaranteeing accurate working position. The underwater electric propeller 324 provides stable surface travel power for the maintenance vessel, while its own gravity helps to accelerate the mode switching process.

[0030] As a preferred option, further, such as Figure 7 and Figure 8As shown, the second ice surface traveling component 33 includes: a fifth L-shaped connecting rod 331, a second transmission rod 332, and a second ice surface electric double spike wheel 333; one end of the fifth L-shaped connecting rod 331 is disposed on the outer wall of another second rack 312; one end of the second transmission rod 332 is disposed on the other end of the fifth L-shaped connecting rod 331; the second ice surface electric double spike wheel 333 is disposed on the other end of the second transmission rod 332, and the second ice surface electric double spike wheel 333 is in contact with the ice surface; the underwater electric propeller 324 is heavier than the second ice surface electric double spike wheel 333. When the pulley 224 is submerged and not lifted or supported by the ice surface, it is supported by the connection between the long rod 322 and the L-shaped transmission rod 222 and the weight of the underwater electric propeller 324 itself, and moves the underwater electric propeller 324 to the bottom of the first U-shaped groove 14 for limiting, and at the same time drives one second rack 312 to drive the second gear 314 to rotate, so that the other second... The rack 312 drives the second ice-surface electric double spike wheel 333 to move upwards into the other two second U-shaped grooves 15 and retracts, switching the underwater electric propeller 324 into surface mode. Through the rigid connection between the fifth L-shaped connecting rod 331 and the second transmission rod 332, the second ice-surface electric double spike wheel 333 and the second rack 312 can move synchronously. Through the weight difference between the underwater electric propeller 324 and the second ice-surface electric double spike wheel 333, combined with the reverse transmission characteristics of the second gear 314, the second ice-surface electric double spike wheel 333 can automatically extend and retract without additional power. The two second U-shaped grooves 15 provide storage space for the second ice-surface electric double spike wheel 333, preventing additional water resistance in surface mode. The double spike structure of the second ice-surface electric double spike wheel 333 improves the grip and anti-slip on the ice surface, enhancing the stability of the maintenance vessel's ice surface operations and the automation of the water-ice mode switching mechanism.

[0031] Its detailed connection methods are well-known technologies in this field. The following mainly introduces the working principle and process, and the specific work is as follows: Initial state: The initial state of this repair vessel is ice surface travel mode. At this time, the bottom of the first ice surface electric double spike wheel 233, the second ice surface electric double spike wheel 333, the pulley 224 and the guide triangle plate 223 are all in contact with the ice surface, and the weed cutter 227 and the underwater electric propeller 324 are in the retracted state. The first ice surface electric double spike wheel 233, the second ice surface electric double spike wheel 333, and the underwater electric propeller 324 are all waterproof and can adapt to the working environment of alternating water and ice. When moving on the ice, the first electric double spike wheel 233 and the second electric double spike wheel 333 on the ice surface provide the propulsion.

[0032] The principle behind switching from ice travel mode to water travel mode: When the maintenance vessel moves from the ice surface into the water, the bottoms of pulley 224, the first electric double spike wheel 233 on the ice surface, and the second electric double spike wheel 333 on the ice surface are no longer lifted or supported by the ice surface.

[0033] The first water-ice switching device 2 switches: the aquatic plant cutter 227 drives the second L-shaped connecting rod 226 to move downward along the rectangular groove 13 by its own gravity, while driving the first L-shaped connecting rod 225 and a first rack 212 connected to it to move along the first limiting groove 211; the first rack 212 drives the first gear 214 to rotate, the first gear 214 drives another first rack 212 to move in the opposite direction, and then drives the first ice surface electric double spike wheel 233 to move upward into one of the two second U-shaped grooves 15 and retract through the third L-shaped connecting rod 231 and the first transmission rod 232; when the second L-shaped connecting rod 226 moves to the bottom of the rectangular groove 13, the mode switching of the first water-ice switching device 2 is completed and the device is limited.

[0034] The second water-ice switching device 3 switches synchronously: the L-shaped transmission rod 222 moves with the first rack 212, and drives the second connecting rod 321 and a second rack 312 connected to it to move along the second limiting concave rod 311 through the long rod 322. The combined effect of the underwater electric propeller 324's own gravity drives the fourth L-shaped connecting rod 323 to drive the underwater electric propeller 324 to move downward to the bottom of the first U-shaped groove 14 for limiting; the second rack 312 drives the second gear 314 to rotate, and the second gear 314 drives another second rack 312 to move in the opposite direction. Then, through the fifth L-shaped connecting rod 331 and the second transmission rod 332, the second ice surface electric double spike wheel 333 moves upward to the other two second U-shaped grooves 15 and retracts, completing the mode switching of the second water-ice switching device 3.

[0035] After the switch is completed, the underwater electric propeller 324 provides the propulsion for water surface movement. In order to prevent aquatic plants from affecting the operation of the electric propeller 324, the forward power of the electric propeller 324 drives the aquatic plant cutter 227 to perform the aquatic plant removal operation on the water surface.

[0036] The principle behind switching from water surface travel mode to ice surface travel mode: When the maintenance vessel sails from the water surface into the ice surface, the underwater electric propeller 324 drives the outer shell 12 to generate inertia, causing part of the outer shell 12 to rush onto the ice surface; and the inclined surface of the guide triangle 223 first contacts the edge of the ice surface to play a guiding role, and then the pulley 224 contacts the ice surface and is lifted up by the ice surface.

[0037] The first water-ice switching device 2 switches: the pulley 224 drives the L-shaped transmission rod 222 to move upward through the guide triangle plate 223, and the L-shaped transmission rod 222 drives a first rack 212 to move upward along the first limiting concave rod 211 through the first connecting rod 221; the first rack 212 drives the first gear 214 to rotate, and the first gear 214 drives another first rack 212 to move downward, and then drives the first ice surface electric double spike wheel 233 to extend downward to contact the ice surface through the third L-shaped connecting rod 231 and the first transmission rod 232.

[0038] The second water-ice switching device 3 switches synchronously: the L-shaped transmission rod 222 drives the second connecting rod 321 and a second rack 312 connected to it to move upward along the second limiting concave rod 311 through the long rod 322; the second rack 312 drives the second gear 314 to rotate, the second gear 314 drives another second rack 312 to move downward, and then drives the second ice surface electric double spike wheel 333 to extend downward to contact the ice surface through the fifth L-shaped connecting rod 331 and the second transmission rod 332.

[0039] After the switch is completed, the first electric double spike wheel 233 and the second electric double spike wheel 333 provide power for ice surface travel, the weed cutter 227 and the underwater electric propeller 324 are retracted upwards, and the maintenance vessel enters the ice surface travel mode.
