Description

Technical Field

[0001] This invention relates to the field of oil and gas extraction equipment technology, and more specifically, to a power catwalk. Background Technology

[0002] In oil and gas extraction, power catwalks are conveying equipment used in the drilling and production field. They transport drilling tools from the ground to the drilling platform from low to high, and vice versa. Currently, most catwalks on the market are hydraulically driven. This type of hydraulic drive is prone to problems such as oil leaks in summer and slow speeds in winter. Furthermore, hydraulic pipelines are complex to install, occupy a large amount of space, and are inconvenient to maintain. During use, the hydraulic power source and pipelines are constantly in a state of vibration and friction, resulting in severe wear.

[0003] In existing technologies, to address the problems associated with hydraulically driven catwalks, an electric drive system has been proposed as a replacement. However, electric drives also present several issues, such as the need for a large driving force in the catwalk itself, necessitating a high-power drive mechanism, resulting in a bulky overall size. Furthermore, the high-power electric drive structure increases overall cost and hinders maintenance. These problems prevent the rational application of electric drives in catwalks. Summary of the Invention

[0004] The technical problem to be solved by this invention is: how to reduce the driving force in a power cat track.

[0005] The present invention provides a power catwalk, including a base, a lifting arm, a boom beam and a ramp, one end of the ramp being connected to one end of the base, the other end of the ramp being used to connect to a drilling platform, and one end of the lifting arm being hinged to the base.

[0006] An electric drive mechanism is provided on the base, and the electric drive mechanism is driven to drive the lifting arm to rotate relative to the base.

[0007] The lifting arm is provided with a sliding mechanism, and the sliding mechanism is movably connected to the lifting arm. The base is also provided with a drive mechanism, which is drivenly connected to the sliding mechanism and is used to drive the sliding mechanism to reciprocate on the lifting arm.

[0008] One end of the cloud beam is hinged to the sliding mechanism, the other end of the cloud beam is used to contact the ramp, and the cloud beam is used to support the drilling tools.

[0009] Optionally, the sliding mechanism comprises a sliding body and a roller rotationally connected with the sliding body, the lifting arm is provided with a track matched with the roller, the track is arranged along the length direction of the lifting arm, the roller is rollingly connected in the track, and the driving mechanism is drivingly connected with the sliding body.

[0010] Optionally, the driving mechanism is an electric winch, both ends of a rope of the electric winch are wound around two pulleys respectively, and the two pulleys are connected with the sliding mechanism.

[0011] Optionally, the electric driving mechanism is an electric telescopic cylinder, both ends of the electric telescopic cylinder are hingedly connected with the base and the lifting arm respectively.

[0012] Optionally, a wheel is rotationally connected with one end of the cloud beam for contacting the ramp, and the ramp is provided with a slide rail matched with the wheel.

[0013] Optionally, the cloud beam is provided with a power assembly and a shuttle vehicle, the power assembly is drivingly connected with the shuttle vehicle, and the shuttle vehicle is driven to reciprocate along the length direction of the cloud beam to push the drilling tool to the drilling platform.

[0014] Optionally, the power assembly comprises an electric motor, a driving wheel, a driven wheel and a chain, the electric motor is drivingly connected with the driving wheel, the driven wheel is drivingly connected with the driving wheel through the chain, and the shuttle vehicle is connected with the chain.

[0015] Optionally, the cloud beam is provided with a groove for accommodating the drilling tool, and the groove is provided with a pipe discharging mechanism for pushing the drilling tool out of the groove.

[0016] Optionally, one end of the ramp is hingedly connected with one end of the base, and the ramp is of a segmented structure, the ramp comprises a plurality of slope bodies, and the slope bodies are sequentially detachably connected.

[0017] Optionally, the cloud beam is provided with a stop lever mechanism on both sides in the length direction, and the stop lever mechanism is used for preventing the drilling tool from falling off the cloud beam.

[0018] Compared with the prior art, the power catwalk has the following technical effects:

[0019] The application drives the lifting arm to rotate relative to the base by setting the electric drive mechanism on the base as the power of the lifting arm, that is, the lifting arm can be driven to lift up and drop down relative to the base, which replaces the hydraulic drive mode in the prior art, and avoids the problems such as oil leakage, complex structure, large space occupation and inconvenience in maintenance caused by the hydraulic drive mode. In use, during the process of conveying the drilling tool to the drilling platform by the power catwalk, one end of the ramp is connected with the base, and the other end can be lapped on the drilling platform. Since the cloud beam is hinged with the lifting arm through the sliding mechanism, the sliding mechanism can also reciprocate on the lifting arm, that is, when the power catwalk is in the initial position, the cloud beam and the lifting arm can be arranged in parallel on the base relative to the base. At this time, the drilling tool can be placed on the cloud beam, the driving mechanism arranged on the base is started, the sliding mechanism is driven to move towards the hinge between the lifting arm and the base, correspondingly, the sliding mechanism drives the cloud beam to move, one end of the cloud beam is in contact with the ramp, which can be specifically an active connection mode such as sliding connection or rolling connection, and the movement of the sliding mechanism on the lifting arm promotes the movement of one end of the cloud beam along the ramp upwards. When the sliding mechanism approaches or will reach the hinge between the lifting arm and the base, the electric drive mechanism is started to drive the lifting arm to rotate relative to the base, that is, the lifting action. Since the hinge point between the cloud beam and the lifting arm is close to the rotation point of the lifting arm when the lifting arm lifts, that is, the force bearing point of the lifting arm bearing the weight of the drilling tool is close to the rotation point, the driving force required by the electric drive mechanism to drive the lifting arm is relatively minimum, which is more labor-saving. When the lifting arm rotates to a certain angle to meet the actual required height and angle, the driving mechanism is started again to drive the sliding mechanism to move away from the hinge between the lifting arm and the base, that is, to drive it to ascend along the lifting arm, correspondingly, the sliding mechanism drives the lifting of the end of the cloud beam hinged with the sliding mechanism, and the opposite end of the cloud beam continues to move upwards along the ramp until reaching the drilling platform. At this time, the cloud beam is also close to parallel with the drilling platform, which facilitates the conveying of the drilling tool to the drilling platform. Conversely, by the cooperation of the electric drive mechanism and the driving mechanism, the drilling tool can be conveyed back to the base labor-savingly and stably. Through the above structure, the original hydraulic drive mode is replaced by the electric drive mechanism, the problems caused by the hydraulic drive are avoided, the driving force of the electric drive mechanism is minimized, the sliding or rolling of the sliding mechanism driven by the driving mechanism is more labor-saving, and then a smaller power electric drive mechanism can be used to realize the conveying of the drilling tool, which reduces the cost and makes the structure more compact. The electric drive mechanism and the driving mechanism are arranged on the base, which is convenient for maintenance, and the application of electric drive on the catwalk is realized.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or embodiment. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or embodiments in a suitable manner.

[0038] To solve the above technical problems, as shown in Figures 1 to 5 The embodiment of the present application provides a power catwalk, which comprises a base 200, a lifting arm 300, a cloud beam 400 and a ramp 100, one end of the ramp 100 is connected with one end of the base 200, the other end of the ramp 100 is used for connecting with a drilling platform 800, one end of the lifting arm 300 is hinged with the base 200, wherein,

[0039] The base 200 is provided with an electric drive mechanism 600, the electric drive mechanism 600 is drivingly connected with the lifting arm 300, and is used for driving the lifting arm 300 to rotate relative to the base 200;

[0040] The lifting arm 300 is provided with a sliding mechanism 500, and the sliding mechanism 500 is movably connected to the lifting arm 300;

[0041] The base 200 is further provided with a driving mechanism 700, which is drivingly connected with the sliding mechanism 500 and used to drive the sliding mechanism 500 to reciprocate on the lifting arm 300.

[0042] One end of the cloud beam 400 is hingedly connected with the sliding mechanism 500, and the other end of the cloud beam 400 is used to contact the ramp 100, and the cloud beam 400 is used to place drilling tools.

[0043] In the embodiment, the electric driving mechanism 600 provided on the base 200 is used as the power of the lifting arm 300, so that the lifting arm 300 can be driven to rotate relative to the base 200, that is, the lifting arm 300 can be driven to lift up and fall down relative to the base 200, which replaces the hydraulic driving mode in the prior art and avoids the problems of oil leakage, complex structure, large space occupation and inconvenience in maintenance caused by the hydraulic driving mode.

[0044] In use, during the process of conveying the drilling tools to the drilling platform 800 by the power catwalk, one end of the ramp 100 is connected with the base 200, and the other end can be lapped on the drilling platform 800. Since the cloud beam 400 is hingedly connected with the lifting arm 300 through the sliding mechanism 500, the sliding mechanism 500 can also reciprocate on the lifting arm 300, that is, in the initial position of the power catwalk, as shown in Figure 2 , it is a planar structural schematic view of the initial state of the power catwalk, and the cloud beam 400 and the lifting arm 300 can be arranged in parallel relative to the base 200 on the base 200;

[0045] At this time, the drilling tools can be placed on the cloud beam 400, and the driving mechanism 700 provided on the base 200 is started to drive the sliding mechanism 500 to move towards the hinged position of the lifting arm 300 and the base 200 (as shown in Figure 2 , the sliding mechanism 500 moves in the left direction, that is, the X-axis is reversed), accordingly, as shown in Figure 3 , the sliding mechanism 500 drives the cloud beam 400 to move, one end of the cloud beam 400 contacts the ramp 100, which can be specifically an active connection mode such as sliding connection or rolling connection, and with the movement of the sliding mechanism 500 on the lifting arm 300, the one end of the cloud beam 400 moves upward along the ramp 100 to perform the first lifting action of the cloud beam 400;

[0046] When the sliding mechanism 500 approaches or will reach the hinged position of the lifting arm 300 and the base 200, as shown in Figure 4 , the lifting arm 300 performs the lifting action, and the electric driving mechanism 600 is started to drive the lifting arm 300 to rotate relative to the base 200, that is, Figure 4When the boom rotates counterclockwise, which is the lifting action, the hinge point between the boom 400 and the lifting arm 300 is close to the rotation point of the lifting arm 300 when it is lifted. In other words, the load-bearing point of the lifting arm 300 that bears the weight of the drill bit is close to its rotation point. At this time, the driving force required for the electric drive mechanism 600 to drive the lifting arm 300 is relatively minimal, which is more labor-saving.

[0047] When the hoisting boom 300 rotates to a certain angle, meeting the actual required height and angle, such as Figure 5 As shown, during the second lifting of the cloud beam 400, the drive mechanism 700 is activated to drive the sliding mechanism 500 away from the hinge point between the lifting arm 300 and the base 200, that is, to drive it to rise along the lifting arm 300. Correspondingly, the sliding mechanism 500 drives the end of the cloud beam 400 that is hinged to the sliding mechanism 500 to rise, and the other end of the cloud beam 400 continues to move upward along the ramp 100 until it reaches the drilling platform 800. At this time, the cloud beam 400 is also close to being parallel to the drilling platform 800, which makes it convenient to remove the drill bit and transport it to the drilling platform 800.

[0048] Conversely, through the cooperation of the electric drive mechanism 600 and the drive mechanism 700, the drill bit can be transported back to the base 200 from the drill platform 800 with ease and stability. This structural design not only replaces the original hydraulic drive with the electric drive mechanism 600, avoiding potential problems caused by hydraulic drives, but also minimizes the driving force of the electric drive mechanism 600. Simultaneously, the drive mechanism 700's driving of the sliding mechanism 500 requires less effort, allowing for the use of a lower-power electric drive mechanism 600 to transport the drill bit. This reduces costs, results in a more compact structure, and facilitates maintenance by mounting both the electric drive mechanism 600 and the drive mechanism 700 on the base 200, achieving a clever and rational application of electric drive on the catwalk.

[0049] It is understood that the base 200, lifting arm 300, cloud beam 400, and ramp 100 can all be designed as elongated structures to accommodate the shapes of drilling tools used in oil and gas extraction (mostly long cylindrical tubes and long rod-shaped structures). Furthermore, the drilling platform 800 is generally located at a height above the ground or horizontal plane. The connection between the ramp 100 and the drilling platform 800 can be achieved through abutment, snap-fit, or detachable connection. For example, one end of the ramp 100 is connected to the drilling platform 800 via a pin for easy assembly and disassembly.

[0050] It should be noted that in practical applications, multiple pipe racks 210 can be set on both sides of the base 200 to hold the drill bit to be transported, and a pipe inlet mechanism 220 can be set between the pipe rack 210 and the base 200. The pipe inlet mechanism 220 can be a pushing structure controlled by an electric cylinder, which facilitates pushing the drill bit on the pipe rack 210 onto the cloud beam 400 in the initial state of this power catwalk.

[0051] Optionally, such asFigure 1 and Figure 6 As shown in the figure, the sliding mechanism 500 comprises a sliding body 510 and a roller 520 rotatably connected with the sliding body 510, the lifting arm 300 is provided with a track matched with the roller 520, the track is arranged along the length direction of the lifting arm 300, the roller 520 is rollingly connected in the track, and the driving mechanism 700 is drivingly connected with the sliding body 510.

[0052] Specifically, the roller 520 is rotatably connected with the sliding body 510 through a pin shaft, forming a structure similar to a trolley, for reciprocating movement in the lifting arm 300, and the track of the lifting arm 300 can be arranged as a semi-closed track, which can meet the movement of the sliding mechanism 500 and limit it from disengaging, which is not limited here. Figure 6 As shown in the figure, it is a view of the sliding mechanism 500 towards the positive direction of the X axis, that is, the side of the sliding mechanism 500 hinged to the girder 400, the sliding body 510 is provided with a hinge part 530 for hinging with the girder 400, which can also be hinged with the girder 400 through a pin shaft, and the side of the lifting arm 300 where the hinge part 530 is hinged to the girder 400 is a hollow structure, facilitating the passage of the girder 400 and the hinge part 530 when the sliding mechanism 500 reciprocates on the lifting arm 300.

[0053] In this embodiment, the sliding mechanism 500 is arranged in the form of a trolley structure with the sliding body 510 rotatably matched with the roller 520, and a corresponding track is arranged on the lifting arm 300, which is more labor-saving when the driving mechanism 700 drives the sliding body 510 to reciprocate along the track, thereby reducing the driving force required when the sliding body 510 drives the girder 400 to lift.

[0054] Alternatively, as shown in the figures, Figure 1 and Figure 6 The driving mechanism 700 is an electric winch, both ends of the lifting arm 300 are respectively provided with a pulley 310, both ends of the rope of the electric winch are respectively wound around the two pulleys and connected with the sliding mechanism 500.

[0055] Specifically, the rope of the electric winch is connected with the sliding body 510, and the electric winch is provided with two winding wheels, or one winding wheel is divided into two parts, that is, two sections of the rope can be extended, one section of the rope is wound around the pulley 310 at one end of the lifting arm 300 (as shown in the figure), and the other section of the rope is wound around the pulley 310 at the other end of the lifting arm 300. Figure 6The rope is connected to one end of the sliding body 510 after passing through the pulley 310 at the top end of the lifting arm 300, and the other section of the rope is connected to the other end of the sliding body 510 after passing through the pulley at the other end of the lifting arm 300, that is, the sliding mechanism 500 can be driven to reciprocate on the lifting arm 300 through the forward and reverse rotation of the electric winch, so that the sliding body 510 can approach the hinge point of the lifting arm 300 and the base 200 to the maximum, that is, the rotation point of the lifting arm 300 relative to the base 200, thereby further reducing the lifting force of the electric drive mechanism 600, and the power demand can be met through the electric drive.

[0056] In the embodiment, the driving mechanism 700 is set as an electric winch, and the pulleys 310 are arranged at the two ends of the lifting arm 300. The rope of the electric winch cooperates with the pulleys 310, and the sliding mechanism 500 can be driven to reciprocate on the lifting arm 300 through the forward and reverse rotation of the electric winch, thereby driving the cloud beam 400 to rise and fall. By taking the electric winch as the driving mechanism 700, maintenance is facilitated, and the driving is more labor-saving and stable and reliable through cooperation with the pulleys 310.

[0057] Optionally, as shown in Figure 1 and Figure 7 The electric drive mechanism 600 is an electric telescopic cylinder, and the two ends of the electric telescopic cylinder are respectively hinged to the base 200 and the lifting arm 300.

[0058] Specifically, the telescopic end of the electric telescopic cylinder is arranged at a position on the lifting arm 300 close to the hinge end of the lifting arm 300 and the base 200, and the fixed end of the electric telescopic cylinder, that is, the cylinder body, is hinged to the base. In this way, a small-size and low-power electric telescopic cylinder can be selected to drive the lifting arm 300 to rotate and lift, and the cylinder body of the electric telescopic cylinder is hinged to the base 200, so that the structure is more stable.

[0059] In the embodiment, the electric drive mechanism 600 is set as an electric telescopic cylinder and is respectively hinged to the base 200 and the lifting arm 300. Since the lifting arm 300 is hinged to the base 200, the lifting arm 300 can be driven to rotate relative to the base 200 through the extension and retraction of the electric telescopic cylinder, that is, to rise and fall. The structure is simple, reasonable in design, easy to implement, and the electric telescopic cylinder is easy to maintain and accurately controlled, so that the overall structure is more reliable and stable.

[0060] Optionally, as shown in Figures 1 to 4 and Figure 11 One end of the cloud beam 400 used to contact the ramp 100 is rotatably connected with a wheel 440, and the ramp 100 is provided with a sliding rail matched with the wheel 440.

[0061] Specifically, in use, one end of the cloud beam 400 is connected to the ramp 100 by rolling connection of the wheels 440 and the slide rail. When the cloud beam 400 is lifted to a certain height, the wheels 440 can slide over the top end of the ramp 100, that is, the end pointed by the positive direction of the Z axis in the drawing, as shown in the figure. The bottom surface of the cloud beam 400, that is, the surface pointed by the negative direction of the Z axis in the drawing, is in contact with the ramp 100 for sliding connection and can also support the cloud beam 400 for lifting and falling movements. Figure 5 As shown in the figure, the bottom surface of the cloud beam 400, that is, the surface pointed by the negative direction of the Z axis in the drawing, is in contact with the ramp 100 for sliding connection and can also support the cloud beam 400 for lifting and falling movements.

[0062] In the embodiment, by using the wheels 440 and the slide rail, the friction and resistance between the cloud beam 400 and the ramp 100 during lifting and falling are reduced, the movement is more smooth and stable, and a smaller driving force can be used to drive the lifting and falling of the cloud beam 400.

[0063] Optionally, as shown in the figures, Figure 1 , Figure 4 and Figures 8 to 11 , the cloud beam 400 is provided with a power assembly and a shuttle vehicle 410. The power assembly is drivingly connected to the shuttle vehicle 410 and used to drive the shuttle vehicle 410 to reciprocate along the length direction of the cloud beam 400 to push the drilling tool to the drilling platform 800.

[0064] Specifically, one end of the shuttle vehicle 410 towards the drilling platform 800 is provided with an arc-shaped part matched with the drilling tool, which facilitates abutting with the end of the drilling tool and stably pushes the drilling tool to move towards the drilling platform 800.

[0065] In the embodiment, by providing the power assembly and the shuttle vehicle 410 on the cloud beam 400, when the drilling tool is transported, the drilling tool is placed on the cloud beam 400. The power assembly drives the shuttle vehicle 410 to push one end of the drilling tool to move towards the drilling platform 800, which facilitates transferring the drilling tool to the drilling platform 800, is convenient to operate, and improves the work efficiency.

[0066] Optionally, as shown in the figures, Figure 1 , Figure 4 and Figures 8 to 11 , the power assembly includes an electric motor 421, a driving wheel 422, a driven wheel 423, and a chain 424. The electric motor 421 is drivingly connected to the driving wheel 422. The driven wheel 423 is drivingly connected to the driving wheel 422 through the chain 424. The shuttle vehicle 410 is connected to the chain 424.

[0067] Specifically, the driving wheel 422 is arranged on the cloud beam 400 close to one end of the sliding mechanism 500, the driven wheel 423 is arranged on the cloud beam 400 close to one end of the ramp 100, the circumferences of the driving wheel 422 and the driven wheel 423 are provided with teeth matched with the chain 424, and the electric motor 421 can rotate forward and reversely to drive the shuttle vehicle 410 to make reciprocating motion on the cloud beam 400. Of course, it needs to be pointed out that the structure of the power assembly can also be a gear and rack structure for driving the shuttle vehicle 410 or a steel wire rope for driving the shuttle vehicle 410 to move, which is not limited here.

[0068] In the embodiment, the shuttle vehicle 410 connected with the chain 424 can make reciprocating motion on the cloud beam 400 through forward and reverse rotation of the electric motor 421 to push the drilling tools, and can return to the original position after pushing, which is simple in structure, reasonable in design, easy to realize and convenient to operate.

[0069] Optionally, as shown in Figure 4 and Figure 11 , the cloud beam 400 is provided with a groove for accommodating the drilling tools, and the groove is provided with a pipe discharging mechanism 430 for pushing the drilling tools out of the groove.

[0070] Specifically, the groove is a V-shaped groove arranged on the upper surface of the cloud beam 400, that is, the side indicated by the positive direction of the Z axis in the drawing, which is more convenient for accommodating the drilling tools. Further, the pipe discharging mechanism 430 is arranged on the two inner side walls of the V-shaped groove and is designed as two groups for simultaneously pushing the two ends of the drilling tools in the length direction. More specifically, the pipe discharging mechanism 430 can be designed as a structure in which the top plate is driven to extend and retract by an electric cylinder, and mounting holes for mounting the electric cylinder and the top plate are arranged on the inner side walls of the V-shaped groove. Under the driving of the electric cylinder, the top plate can push the drilling tools out, which is convenient for taking the drilling tools out of the groove of the cloud beam 400. It needs to be pointed out that the pipe discharging mechanism 430 is generally used in the process of conveying the drilling tools from the drilling platform 800 to the ground or a horizontal surface, that is, when the cloud beam 400 is parallelly attached to the base 200 in the initial state of the power catwalk and the drilling tools are taken out of the cloud beam 400, at this time, the pipe discharging mechanism 430 can push the drilling tools out of the groove on the cloud beam 400 to the pipe rack 210 on the two sides of the base 200.

[0071] In the embodiment, the pipe discharging mechanism 430 is arranged to facilitate the operation of taking the drilling tools out of the cloud beam 400 in the process of conveying the drilling tools from the drilling platform 800 to the ground or a horizontal surface, which is convenient to use and improves the work efficiency.

[0072] Optionally, the cloud beam 400 is provided with a stop lever mechanism on both sides in the length direction, which is used to prevent the drill from falling off the cloud beam 400.

[0073] Specifically, the stop lever mechanism is arranged on both sides of the cloud beam 400 in the length direction, that is, on both sides of the groove, to prevent the drill on the cloud beam 400 from falling off the side, and the stop lever mechanism can also be designed as a structure in which the electric cylinder control rod is extended and retracted. When the pipe discharging mechanism 430 needs to be used, the electric cylinder control rod of the stop lever mechanism is retracted to push the drill out of the groove by the pipe discharging mechanism 430. During the transportation of the drill on the cloud beam 400, the electric cylinder control rod of the stop lever mechanism is extended to stop the drill from falling off.

[0074] In this embodiment, the stop lever mechanism is arranged to effectively prevent the drill from falling off the cloud beam 400 during the transportation of the drill on the cloud beam 400, thereby making the overall structure more reasonable and improving the safety in use.

[0075] Optionally, as shown in Figure 1 and Figure 2 , one end of the ramp 100 is hinged to one end of the base 200, and the ramp 100 is a segmented structure. The ramp 100 includes a plurality of slope bodies which are detachably connected in sequence to form the ramp 100.

[0076] Specifically, the hinged ends of the ramp 100 and the base 200 are provided with hinge seats which are hinged by a pin shaft. The structures of the plurality of slope bodies can be the same and are designed in a segmented manner along the length direction of the ramp 100. In actual application, a suitable number of slope bodies can be selected for assembly to form the ramp 100 according to the height of the drilling platform 800 and in combination with the relative position and angle of the base 200 and the drilling platform 800. The lifting angle of the lifting arm 300 and the position of the sliding mechanism 500 can be adjusted to adapt to the drilling platform 800 of different heights, so that one catwalk can adapt to the drilling platform 800 of different heights, and the application range is wider.

[0077] In this embodiment, the ramp 100 is arranged in a segmented structure to adapt to the drilling platform 800 of different heights, thereby improving the application range of the catwalk. Moreover, the ramp 100 is hinged to the base 200. When the drill conveying operation is not performed, the ramp 100 can be relatively rotated relative to the base 200 and is wholly buckled on the base 200, so that the catwalk is in the form of a nearly cuboid structure, thereby making the overall structure more compact and facilitating the transportation between sites.

[0078] Although the present disclosure discloses as above, the protection scope of the present disclosure is not limited to this. The person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present disclosure.
