Description

Technical Field

[0001] This application relates to the field of shearing technology, and in particular to a shearing device. Background Technology

[0002] In related technologies, operators apply pressure to the material to be sheared using a cutting tool, creating relative movement between the tool and the material, thereby dividing or cutting it. However, in the shearing process of these technologies, the material to be sheared is not very stable and is prone to shaking. For example, when shearing pipes being removed from a research reactor, because the pipes are generally long and have curved outer surfaces, they tend to deviate from the shearing position when the operator uses the cutting tool, making shearing difficult. Summary of the Invention

[0003] In view of this, the main objective of the embodiments of this application is to provide a shearing device that can improve the stability of the material to be sheared during the shearing process.

[0004] To achieve the above objectives, the technical solution of this application embodiment is implemented as follows: This application provides a shearing device, including: Supporting entity; A clamping mechanism is disposed on the support body. The clamping mechanism includes a first clamping component and a second clamping component. The first clamping component includes a first clamping member, and the second clamping component includes a second clamping member. Both the first clamping member and the second clamping member are movable relative to the support body, and the first clamping member and the second clamping member are spaced apart to form a first material passage space for the material to be cut to pass through. The clamping mechanism has a clamping state in which the first clamping member and the second clamping member clamp the material to be cut, and a loosening state in which the first clamping member and the second clamping member release the material to be cut. The first clamping member moves relative to the support body to switch the clamping mechanism between the clamping state and the loosening state. When the clamping mechanism is in the clamping state, the second clamping member moves relative to the support body to drive the material to be cut to move relative to the support body along the feeding direction. A shearing mechanism is disposed on one side of the first material feeding space along the feeding direction.

[0005] In one embodiment, the support body includes a mounting base, and the first clamping assembly further includes a first driving member disposed on the mounting base. The first driving member is drivenly connected to the first clamping member to drive the first clamping member to move along the interval direction between the first clamping member and the second clamping member.

[0006] In one embodiment, the support body includes a mounting base, and the second clamping assembly further includes a second driving member. The second clamping member is rotatably disposed on the mounting base, and the second driving member is drivenly connected to the second clamping member to drive the second clamping member to rotate.

[0007] In one embodiment, the first clamping assembly further includes a first guide rail and a clamping slide plate disposed on the mounting base. The first clamping member includes a roller, which is rotatably disposed on the clamping slide plate. The clamping slide plate is movably disposed on the first guide rail along the spacing direction between the first clamping member and the second clamping member. The first driving member is drivenly connected to the clamping slide plate.

[0008] In one embodiment, the support body includes a mounting base, and the shearing mechanism is disposed on the mounting base. The shearing mechanism includes a third driving member, a first shearing member, and a second shearing member. The first shearing member and the second shearing member are spaced apart to form a second material passage space. The second material passage space and the first material passage space are interconnected. The third driving member is drivenly connected to the first shearing member to drive the first shearing member to move along the spaced direction between the first shearing member and the second shearing member.

[0009] In one embodiment, the shearing mechanism further includes a second guide rail and a slider disposed on the mounting base, the first shearing member being disposed on the slider, the slider being movably disposed on the second guide rail along the interval direction between the first shearing member and the second shearing member, and the third driving member being drivenly connected to the slider.

[0010] In one embodiment, the shearing device further includes a guide cover disposed on the support body and located on the side of the clamping mechanism away from the shearing mechanism. The guide cover has a guide cavity, which is open on opposite sides along the feeding direction to form material passages respectively. The guide cavity communicates with the first material passage space. The spatial size of the guide cavity gradually decreases from the side away from the clamping mechanism to the side closer to the clamping mechanism.

[0011] In one embodiment, the support body includes a support frame extending along the height direction, the clamping mechanism and the shearing mechanism are disposed on the support frame, and a portion of the top part of the support frame protrudes laterally to form a limiting frame.

[0012] In one embodiment, the shearing device further includes a guide and a collection box, the guide and the collection box being disposed on the side of the shearing mechanism away from the clamping mechanism, the collection box having a collection cavity that is open on the side near the clamping mechanism, the guide having a guide ramp that extends one end to the shearing mechanism and the other end to the opening of the collection cavity.

[0014] This application provides a shearing device, which includes a support body, a clamping mechanism, and a shearing mechanism. The clamping mechanism has a clamping state where a first clamping member and a second clamping member clamp the material to be sheared, and a loosening state where the first clamping member and the second clamping member release the material to be sheared. The first clamping member moves relative to the support body to switch the clamping mechanism between the clamping state and the loosening state. On the one hand, by moving the first clamping member, the clamping mechanism can clamp the material to be sheared according to the operator's needs, which can limit the shaking of the material to be sheared, thereby improving the stability of the material to be sheared during the shearing process. At the same time, by moving the first clamping member, the clamping mechanism can release the material to be sheared according to the operator's needs, thereby facilitating the removal of the material to be sheared or refeeding. On the other hand, when the clamping mechanism is in the clamping state, the second clamping member moves relative to the support body to drive the material to be sheared to move relative to the support body along the feeding direction. Therefore, the second clamping member can clamp the material to be cut with the first clamping member while driving the material to be cut to move along the feeding direction, which can achieve a better feeding effect and facilitate the shearing mechanism to continuously cut the material to be cut, thereby greatly improving the shearing effect.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0020] One embodiment of this application provides a shearing device; please refer to [link / reference]. Figures 1 to 5 The shearing device includes a support body 10, a clamping mechanism 20, and a shearing mechanism 30.

[0021] Please see Figures 6 to 11 The clamping mechanism 20 is disposed on the support body 10. The clamping mechanism 20 includes a first clamping component 21 and a second clamping component 22. The first clamping component 21 includes a first clamping member 211, and the second clamping component 22 includes a second clamping member 221. Both the first clamping member 211 and the second clamping member 221 can move relative to the support body 10. The first clamping member 211 and the second clamping member 221 are spaced apart to form a first material passage space 21a, which is used for the material to be cut to pass through.

[0022] The clamping mechanism 20 has a clamping state in which the first clamping member 211 and the second clamping member 221 clamp the material to be cut, and a loosening state in which the first clamping member 211 and the second clamping member 221 release the material to be cut. The first clamping member 211 moves relative to the supporting body 10 so that the clamping mechanism 20 switches between the clamping state and the loosening state.

[0023] When the clamping mechanism 20 is in the clamping state, the second clamping member 221 moves relative to the supporting body 10 to drive the material to be cut to move relative to the supporting body 10 along the feeding direction.

[0024] The shearing mechanism 30 is located on one side of the first material feeding space 21a along the feeding direction.

[0025] Specifically, the type of material to be sheared by the shearing device is not limited. For example, if the material to be sheared is a pipe, the shearing device can be used to shear pipes being removed from a research reactor. Of course, the shearing device can also shear other types of materials.

[0026] The support body 10 is the main structure that provides support in the shearing device. It can be used to install the clamping mechanism 20 and the shearing mechanism 30. The specific type of the support body 10 is not limited. For example, the support body 10 can be a frame structure or a shell structure.

[0027] The clamping mechanism 20 is a structure in the shearing device used to clamp the material to be sheared. By setting the clamping mechanism 20, the material to be sheared can be better prevented from shaking during the shearing process.

[0028] Specifically, the clamping mechanism 20 clamps the material to be cut by the interaction of the first clamping member 211 and the second clamping member 221, thereby limiting the shaking of the material to be cut.

[0029] In fact, the first clamping member 211 is movable relative to the second clamping member 221 and the supporting body 10. By moving, the first clamping member 211 can adjust the distance between itself and the second clamping member 221, thus adjusting the size of the first material passage space 21a. Therefore, when the first clamping member 211 moves to make the size of the first material passage space 21a sufficiently large, the material to be cut can freely enter and exit the first material passage space 21a, i.e., the loose state of the clamping mechanism 20. Simultaneously, when the first clamping member 211 moves to make the size of the first material passage space 21a sufficiently small, the first clamping member 211 and the second clamping member 221 can jointly press against the material to be cut from opposite sides, thereby achieving the function of clamping the material to be cut, i.e., the clamping state of the clamping mechanism 20.

[0030] It should be noted that the specific movement mode of the first clamping member 211 is not limited, as long as it can enable the clamping mechanism 20 to switch between the clamping state and the loosening state through the movement of the first clamping member 211. For example, the first clamping member 211 can be a translation, rotation, extension or other arbitrary type of movement mode.

[0031] The second clamping member 221 is also movable relative to the first clamping member 211 and the supporting body 10. In the clamped state, the second clamping member 221, through its movement, can move the material to be cut within the first material feeding space 21a, causing it to move towards the shearing mechanism 30 along the feeding direction. Thus, when the shearing mechanism 30 cuts off a section of the material to be cut, the movement of the second clamping member 221 allows the material to move towards the shearing mechanism 30, facilitating the shearing mechanism 30 to continue cutting the next section of the material, and so on. This effectively achieves better material feeding to the shearing mechanism 30, significantly improving shearing efficiency.

[0032] It should be noted that the first clamping member 211 can switch the state of the clamping mechanism 20 through movement, and the second clamping member 221 can move the material to be cut through movement. When the first clamping member 211 and the second clamping member 221 are not moving, the clamping mechanism 20 can be stably maintained in its current state. Furthermore, whether the first clamping member 211 and the second clamping member 221 are moving can be controlled according to the operator's needs, and the specific implementation method is not limited.

[0033] For example, please refer to Figures 6 to 9 The support body 10 includes a mounting base 11, and the first clamping assembly 21 further includes a first driving member 212 disposed on the mounting base 11. The first driving member 212 is drivenly connected to the first clamping member 211 to drive the first clamping member 211 to move along the interval direction between the first clamping member 211 and the second clamping member 221. Thus, the state switching of the clamping mechanism 20 can be achieved better.

[0034] In other words, when the operator needs to switch states, the first driving member 212 can drive the first clamping member 211 to move, thereby causing the first clamping member 211 to move along the interval direction.

[0035] Specifically, under the driving action of the first driving member 212, the first clamping member 211 moves towards the second clamping member 221, thereby reducing the size of the first material passage space 21a until it can clamp the material to be cut. Furthermore, under the driving action of the first driving member 212, the first clamping member 211 moves away from the second clamping member 221, thereby increasing the size of the first material passage space 21a until it can release the material to be cut.

[0036] It should be noted that the specific structural form of the first driving component 212 is not limited. For example, the first driving component 212 can be a first hydraulic cylinder. Of course, the first driving component 212 can also adopt other driving structures.

[0037] For example, please refer to Figures 6 to 9 The support body 10 includes a mounting base 11, and the second clamping assembly 22 includes a second driving member. The second clamping member 221 is rotatably mounted on the mounting base 11, and the second driving member is driven to rotate the second clamping member 221. This allows for a better supply of material to be cut.

[0038] In other words, when the operator needs to supply the material to be cut to the shearing mechanism 30, the second driving component can drive the second clamping component 221 to rotate, thereby causing the material to be cut to move along the feeding direction.

[0039] It should be noted that the specific structural form of the second drive component is not limited. For example, the second drive component can be a hydraulic motor. Of course, other drive structures can also be used for the second drive component.

[0040] The shearing mechanism 30 is a mechanism in the shearing device that can shear the material to be sheared. The shearing mechanism 30 is located on one side of the first material passage space 21a along the feeding direction, thereby facilitating the shearing of the material to be sheared by the shearing mechanism 30 as it passes through the first material passage space 21a.

[0041] In the shearing device of this application embodiment, the clamping mechanism 20 has a clamping state where the first clamping member 211 and the second clamping member 221 clamp the material to be cut, and a loosening state where the first clamping member 211 and the second clamping member 221 release the material to be cut. The first clamping member 211 moves relative to the supporting body 10 to allow the clamping mechanism 20 to switch between the clamping state and the loosening state. On the one hand, by moving the first clamping member 211, the clamping mechanism 20 can clamp the material to be cut according to the operator's needs, which can limit the shaking of the material to be cut, thereby improving the stability of the material to be cut during the shearing process. At the same time, by moving the first clamping member 211, the clamping mechanism 20 can release the material to be cut according to the operator's needs, thereby facilitating the removal of the material to be cut or refeeding. On the other hand, when the clamping mechanism 20 is in the clamping state, the second clamping member 221 moves relative to the supporting body 10 to drive the material to be cut to move relative to the supporting body 10 along the feeding direction. Therefore, the second clamping member 221 can clamp the material to be cut with the first clamping member 211 while driving the material to be cut to move along the feeding direction, which can achieve a better feeding effect and facilitate the shearing mechanism 30 to continuously cut the material to be cut, thereby greatly improving the shearing effect.

[0042] In one embodiment, please refer to Figures 6 to 9 as well as Figure 12 The first clamping assembly 21 further includes a first guide rail 213 and a clamping slide plate 214 disposed on the mounting base 11. The first clamping member 211 includes a roller, which is rotatably disposed on the clamping slide plate 214. The clamping slide plate 214 is movably disposed on the first guide rail 213 along the interval direction between the first clamping member 211 and the second clamping member 221. The first driving member 212 is drivenly connected to the clamping slide plate 214. Thus, the movement of the first clamping member 211 can be guided better.

[0043] Specifically, the first guide rail 213 may extend only a portion of its area along the spacing direction between the first clamping member 211 and the second clamping member 221, or it may extend its entire area along the spacing direction.

[0044] The first guide rail 213 and the pressing slide plate 214 are slidably connected, which facilitates the movement of the pressing slide plate 214 and the first pressing member 211.

[0045] It should be noted that the specific number of the first guide rail 213 is not limited, and the first clamping component 21 may include only one guide rail or multiple guide rails.

[0046] The first driving component 212 drives the pressing slide plate 214, allowing the pressing slide plate 214 to slide on the first guide rail 213, thereby driving the first pressing component 211 to move. It should be noted that by setting the first guide rail 213, the pressing slide plate 214 can be guided to slide better, allowing the first pressing component 211 to move better along the designed trajectory.

[0047] The first clamping member 211 may consist only of a roller, or it may include other structures. By rotatably mounting the roller on the clamping slide plate 214, on the one hand, when the first driving member 212 drives the clamping slide plate 214 to move, the clamping slide plate 214 can drive the roller to move in one direction. On the other hand, the roller and the clamping slide plate 214 are rotatably connected, so when the clamping mechanism 20 is in the clamping state, when the second clamping member 221 moves the material to be cut, the material to be cut can also drive the roller to rotate. Thus, the roller can rotate relative to the material to be cut, which can reduce the mutual friction between the two and can better reduce the wear between the roller and the material to be cut.

[0048] In some embodiments, please refer to Figure 13 The second clamping member 221 is also a roller structure, such as a knurled roller. This allows the second clamping member 221 to move the material to be sheared while also reducing wear between the two.

[0049] In one embodiment, please refer to Figure 8 , Figure 10 and Figure 11 The support body 10 includes a mounting base 11, and a shearing mechanism 30 is mounted on the mounting base 11. The shearing mechanism 30 includes a third driving member 31, a first shearing member 32, and a second shearing member 33. The first shearing member 32 and the second shearing member 33 are spaced apart to form a second material passage space 30a. The second material passage space 30a and the first material passage space 21a are interconnected. The third driving member 31 is drivenly connected to the first shearing member 32 to drive the first shearing member 32 to move along the interval direction between the first shearing member 32 and the second shearing member 33. Thus, the material to be sheared can be sheared better.

[0050] Specifically, the third driving component 31 is a driving structure capable of moving away from the first shearing component 32, and its specific structural form is not limited. For example, the third driving component 31 is a second hydraulic cylinder. Of course, the third driving component 31 can also adopt other driving structures.

[0051] The second material passage space 30a and the first material passage space 21a are interconnected. When the second clamping member 221 moves, the material to be cut enters the second material passage space 30a through the first material passage space 21a under the action of the second clamping member 221. The operator can use the third driving member 31 to drive the first shearing member 32 to move towards the second shearing member 33 until it cuts the material to be cut in the second material passage space 30a together with the second shearing member 33.

[0052] The specific structural form of the first shearing component 32 and the second shearing component 33 is not limited, as long as they can cooperate with each other to shear the material to be sheared.

[0053] For example, the first shearing element 32 is a moving blade, and the second shearing element 33 is a stationary blade.

[0054] In one specific embodiment, the first shearing member 32 and the second shearing member 33 are located on the same horizontal plane along the height direction, so that they can cooperate with each other to achieve shearing.

[0055] In one specific embodiment, the first shear member 32 and the second shear member 33 are staggered along the height direction. That is, the first shear member 32 and the second shear member 33 are not located on the same horizontal plane. This prevents the first shear member 32 and the second shear member 33 from colliding with each other.

[0056] In one embodiment, please refer to Figure 8 , Figure 10 and Figure 11 The shearing mechanism 30 also includes a second guide rail 34 and a slider 35 disposed on the mounting base 11. A first shearing member 32 is disposed on the slider 35. The slider 35 is movably disposed on the second guide rail 34 along the interval direction between the first shearing member 32 and the second shearing member 33. A third driving member 31 is drivenly connected to the slider 35. Thus, the first shearing member 32 can be guided to move better.

[0057] Specifically, the second guide rail 34 may extend only a portion of its area along the spacing direction between the first shear member 32 and the second shear member 33, or it may extend its entire area along the spacing direction.

[0058] The second guide rail 34 and the slider 35 are slidably connected, which facilitates the movement of the slider 35 and the first shearing member 32.

[0059] It should be noted that the specific number of the second guide rails 34 is not limited, and the shearing mechanism 30 may include only one guide rail or multiple guide rails.

[0060] The third driving component 31 drives the slider 35, enabling the slider 35 to slide on the second guide rail 34, thereby driving the first shearing component 32 to move. It should be noted that by setting the second guide rail 34, the slider 35 can be guided to slide better, allowing the first shearing component 32 to move better along the designed trajectory.

[0061] It should be noted that the specific location of the first shearing component 32 is not limited.

[0062] For example, the first shearing member 32 is disposed on the side of the sliding member 35 near the mounting base 11. This facilitates the first shearing member 32 in cutting the material to be cut, and also allows the first shearing member 32 to be hidden, thereby improving safety performance.

[0063] In one embodiment, please refer to Figure 1 and Figure 6 The shearing device also includes a guide cover 40, which is mounted on the support body 10 and located on the side of the clamping mechanism 20 away from the shearing mechanism 30. The guide cover 40 has a guide cavity 40a, which opens on opposite sides along the feeding direction to form material passages. The guide cavity 40a communicates with the first material passage space 21a. The spatial size of the guide cavity 40a gradually decreases from the side away from the clamping mechanism 20 to the side closer to the clamping mechanism 20. Thus, the guide cover 40 has a good guiding effect and can better guide the material to be sheared into the first material passage space 21a.

[0064] Specifically, the guide cover 40 and the shearing mechanism 30 are located on opposite sides of the clamping mechanism 20. The size of the guide cavity 40a within the guide cover 40 gradually decreases towards the clamping mechanism 20. This allows for a larger material passage on the side of the guide cover 40 away from the clamping mechanism 20, facilitating the entry of the material to be sheared. Simultaneously, it allows for a smaller material passage on the side of the guide cover 40 closer to the clamping mechanism 20, enabling more accurate entry of the material into the first material passage space 21a.

[0065] The specific shape of the guide cavity 40a of the guide cover 40 is not limited; for example, the guide cavity 40a is an inverted trapezoid.

[0066] In one embodiment, the support body 10 includes a support frame 12 extending along the height direction, a clamping mechanism 20 and a shearing mechanism 30 disposed on the support frame 12, and a portion of the top part of the support frame 12 protrudes laterally to form a limiting frame.

[0067] Specifically, the limiting frame can be used to limit the overall position of the shearing device. It abuts against the external structure and can achieve a fixing effect.

[0068] When shearing the pipes being removed from the research reactor, the radiation can be shielded by underwater shearing because the pipes are highly radioactive.

[0069] For example, please see Figure 15 The shearing device is used to cooperate with the working water tank 70. The working water tank 70 has at least one water storage cavity 70a for storing water, and the shearing device is inserted into the water storage cavity 70a through the top opening of the water storage cavity 70a. By abutting against the wall of the top opening of the water storage cavity 70a by a limiting frame, the shearing device is prevented from falling further, thereby achieving a stable connection between the shearing device and the working water tank 70.

[0070] It should be noted that the specific connection methods between the clamping mechanism 20 and the shearing mechanism 30 and the support frame 12 are not limited. They can be fixedly connected or can be raised and lowered along the height direction.

[0071] In one specific embodiment, the shearing device further includes a hoisting fixture disposed on the top of the limiting frame. The hoisting fixture can be used for hoisting by a workshop crane so that the workshop crane can hoist the shearing device into the working water tank 70.

[0072] It should be noted that the hoisting fixtures may or may not be removed during the shearing process.

[0073] The specific material of the limit frame is not limited. For example, if the limit frame is made of stainless steel, the use of stainless steel can better ensure the structural stability of the shearing device during shearing.

[0074] In one embodiment, please refer to Figures 1 to 3 The shearing device also includes a guide member 50 and a collection box. The guide member 50 and the collection box are located on the side of the shearing mechanism 30 away from the clamping mechanism 20. The collection box has a collection cavity, which is open on the side closest to the clamping mechanism 20. The guide member 50 has a guide slope 50a, one end of which extends to the shearing mechanism 30, and the other end extends to the opening of the collection cavity. This allows for better guidance of the sheared material into the collection cavity.

[0075] Specifically, both the guide member 50 and the collection box are located on the side of the shearing mechanism 30 opposite to the clamping mechanism 20. In fact, along the height direction, the clamping mechanism 20 is located on the top side of the shearing mechanism 30, while the guide member 50 and the collection box are located on the bottom side. Therefore, after the shearing mechanism 30 has finished shearing the material, the sheared material will fall onto the guide member 50 under its own gravity. Guided by the guide member 50, it moves along the guide slope 50a into the collection chamber, thus completing the collection.

[0076] It is understandable that the guide slope 50a is an inclined surface that is inclined relative to the horizontal plane, which facilitates the movement of the material after shearing into the collection chamber.

[0077] The collection box can be movably mounted on the support body 10, so that after the collection in the collection chamber is completed, the collection box can be moved to facilitate the removal of the sheared material.

[0078] In one specific embodiment, the shearing device further includes monitoring equipment and a hook mounted on the support body 10, with the collection box suspended from the support body 10 via the hook. When the operator monitors the completion of the shearing process via the monitoring equipment, the collection box can be lifted above the water surface via the hook to complete the collection.

[0079] In one embodiment, the shearing device further includes a housing assembly with a mounting cavity, in which the support body 10, the clamping mechanism 20, and the shearing mechanism 30 are all disposed. The mounting cavity is closed circumferentially and at the bottom. This provides a more stable shearing environment.

[0080] Specifically, the specific structural form of the shell assembly is not limited, as long as it can form a closed space around the perimeter and bottom.

[0081] For example, the housing assembly is a sealed water tank. Around the periphery of the sealed water tank, three of its circumferential sides and the bottom are enclosed shells, while the other circumferential side of the sealed water tank is provided with an openable and closable sealed door. The shearing device also includes a remote control mechanism 60 and a cylinder, which is controlled by the remote control mechanism 60 to drive the sealing door to open and close.

[0082] It should be noted that the specific material of the shell components can be determined based on the specific circumstances. For example, using stainless steel for the shell components can improve structural strength and prevent rusting during underwater operation.

[0083] In one embodiment, please refer to Figure 14 The shearing device also includes a remote control mechanism 60, which includes a power unit connected to the shearing mechanism 30 to provide power to the shearing mechanism 30. This enables remote control of the shearing mechanism 30 to shear the material to be sheared.

[0084] Specifically, the remote control mechanism 60 is a mechanism located away from the clamping mechanism 20 and the shearing mechanism 30, and it can be used to control the shearing mechanism 30 to cut.

[0085] In related technologies, the cutting tools cannot be operated remotely. When cutting pipes removed from the research reactor, the pipes are radioactive, which can easily cause harm to the operators.

[0086] By employing a remote control mechanism 60, the clamping mechanism 20 and the shearing mechanism 30 can be easily placed in deeper water. Operators do not need to perform close-range shearing; they can operate remotely, which can effectively achieve underwater shearing, reduce the radiation dose received by operators, and facilitate operation.

[0087] It should be noted that the remote control mechanism 60 may also include other structures.

[0088] For example, the remote control mechanism 60 includes a monitoring display, operation buttons, a small air compressor, and a pneumatic-hydraulic interface. The monitoring display is connected to the lighting and camera mechanism of the shearing device, allowing real-time display of the shearing status of the shearing mechanism 30. The small air compressor provides air to the cylinders that open and close the sealing door of the housing assembly, and the power unit provides power to the shearing mechanism 30, such as hydraulic pressure. The operation buttons control the shearing, the opening and closing of the sealing door, and the system power supply. By setting up the remote control mechanism 60, protection functions such as remote start / stop and automatic power-off in abnormal situations can be effectively achieved.

[0089] In one specific embodiment, the second driving component includes a servo motor and a transmission rod. The servo motor drives the second clamping member 221 to rotate via the transmission rod. The servo motor can be positioned above the water surface and transmit power to the second clamping member 221 via the transmission rod. Thus, by setting the rotation amount of the servo motor, the feed amount of the material to be cut can be controlled, thereby controlling the cutting length of the material to be cut.

[0090] In one specific embodiment, the mounting base 11 is a 40mm thick steel plate with a rust-proof surface treatment, which enables it to adapt well to the underwater operating environment.

[0091] In one specific embodiment, the third driving component 31 is a special hydraulic cylinder for shearing machines, which has advantages such as large thrust and can complete the shearing of high-strength pipes.
