Description

Technical Field

[0001] This application relates to the field of power system operation and maintenance technology, and in particular to a grid sealing device, its usage method, and a drone. Background Technology

[0002] To ensure the safety of transmission line inspection and maintenance operations, insulating nets must be installed below the work area or on both sides of the conductors. The nets form a physical protective barrier to prevent workers from accidentally falling and tools and materials from falling and damaging the facilities below, while also avoiding secondary damage to the transmission lines themselves during the operation.

[0003] Traditionally, workers use aerial work platforms or climb towers to reach the conductor, secure the insulated mesh with a traction rope to the conductor, and then manually drag the rope to unfold the mesh along the conductor. When encountering obstacles, such as vibration dampers or spacers on vertical double-split lines, 2-3 workers are required to work together. For example, one person can hold the conductor, another can use specialized tools to lift the mesh or temporarily remove the obstacle, and the third can continue to drag the mesh across the obstacle before resuming operations. Even if there are technologies that utilize automated devices for mesh installation, these devices are often complex in structure, rarely have the ability to cross obstacles, and require personnel to go outside the work area for installation, thus posing certain risks during use. Summary of the Invention

[0004] This application proposes a net sealing device to effectively solve the technical problems of low efficiency, complex structure and imperfect function in net sealing operations in related technologies.

[0005] This application also proposes a method of using the above-mentioned sealing device.

[0006] This application also proposes a drone that includes the aforementioned netting device.

[0007] The first aspect of this application provides a netting device, including: a frame, a drive wheel component, a driven wheel component, and an obstacle avoidance mechanism;

[0008] The drive wheel assembly is mounted on the frame and is used to travel on the conductor;

[0009] The driven wheel component is positioned relative to the driving wheel component to cooperate in pressing the wire;

[0010] The obstacle avoidance mechanism is mounted on the frame and is used to drive the driven wheel component to move, so that the driven wheel component can switch between the clamping position of the clamping wire and the avoidance position of the obstacle.

[0011] Furthermore, the obstacle avoidance mechanism includes a drive assembly, a first slider, a second slider, a guide plate, and a rocker arm component;

[0012] A track groove is formed on the guide plate, and the first slider and the second slider are slidably disposed in the track groove in sequence.

[0013] The driven wheel component is mounted on the second slider;

[0014] The driving component is used to drive the first slider to move;

[0015] The first slider is connected to the second slider via the rocker component, so that the second slider can drive the driven wheel component to the pressing position or the avoidance position.

[0016] Furthermore, the trajectory groove includes a straight segment and a curved segment, one end of the straight segment is connected to one end of the curved segment, the pressing position is set at a position relatively close to the other end of the straight segment, and the avoidance position is set at a position relatively close to the other end of the curved segment.

[0017] Furthermore, when in the clamping position, the axis of the driven wheel component extends perpendicularly to the extension direction of the straight segment;

[0018] And / or, when in the avoidance position, the axis of the driven wheel component extends parallel to the extension direction of the straight segment.

[0019] Furthermore, the driving assembly includes a driving member and a lead screw, the first slider is connected to the lead screw in a transmission manner, and the driving member is used to drive the lead screw to rotate, thereby driving the first slider to move.

[0020] Furthermore, the drive assembly includes a guide shaft arranged parallel to the lead screw, the guide shaft being used to guide the movement of the first slider.

[0021] Furthermore, multiple sets of driven wheel components and obstacle avoidance mechanisms are provided in a one-to-one correspondence, and multiple drive wheel components are provided, with each drive wheel component located between two adjacent driven wheel components.

[0022] Furthermore, each of the obstacle avoidance mechanisms is used to drive the movement of each of the driven wheel components, so that the driven wheel components move synchronously or sequentially.

[0023] As can be seen from the above technical solutions, the embodiments of this application have at least the following beneficial effects: the drive wheel component moves autonomously and unfolds the sealing net, and the driven wheel component is in the pressing position, which can cooperate with the drive wheel component to hug and press the conductor, ensuring stable movement on the conductor. When encountering obstacles, the driven wheel component is adjusted to the avoidance position in time through the obstacle avoidance mechanism, so as to realize the autonomous crossing of obstacles such as spacers, vibration dampers, and connecting pipes, breaking through the limitation of existing devices that cannot cross obstacles, improving the sealing efficiency, and ensuring operational safety.

[0024] A second aspect of this application provides a method for using a sealing device, comprising the following steps:

[0025] Adjust the driven wheel component to the avoidance position;

[0026] The sealing device is attached to the conductor, enabling the drive wheel component to move on the conductor;

[0027] The obstacle avoidance mechanism drives the driven wheel component to move, so that the driven wheel component reaches the pressing position, and the drive wheel component travels on the guide wire;

[0028] When the driven wheel component encounters an obstacle, the obstacle avoidance mechanism drives the driven wheel component to move, so that the driven wheel component reaches the avoidance position;

[0029] The drive wheel component continues to move until the driven wheel component crosses the obstacle, at which point the obstacle avoidance mechanism drives the driven wheel component to move, causing the driven wheel component to return to the pressing position;

[0030] Repeat the above steps to complete the net sealing operation.

[0031] A third aspect of this application provides a drone, including a netting device as described in the first aspect of this application.

[0032] It is easy to understand that the method of using the net sealing device in the second aspect embodiment of this application and the drone in the third aspect embodiment of this application both have the same technical effects as the net sealing device in the first aspect embodiment, and therefore will not be described again.

[0051] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0052] See Figures 1 to 8 As shown, an embodiment of the first aspect of this application discloses a net sealing device, including a frame 100, a drive wheel component 200, a driven wheel component 300, and an obstacle avoidance mechanism 400;

[0053] A drive wheel assembly 200 is mounted on the frame 100 and is used to travel on the conductor 600; a driven wheel assembly 300 is disposed relative to the drive wheel assembly 200 to cooperate in pressing the conductor 600; an obstacle avoidance mechanism 400 is mounted on the frame 100 and is used to drive the driven wheel assembly 300 to move so that the driven wheel assembly 300 can switch between a pressing position that presses the conductor 600 and a avoidance position that avoids the obstacle 500.

[0054] In the embodiments of this application, the drive wheel component 200 moves autonomously and unfolds the sealing net. The driven wheel component 300 is in a pressing position and can cooperate with the drive wheel component 200 to hug and press the conductor 600, ensuring stable movement on the conductor 600. When encountering an obstacle 500, the obstacle avoidance mechanism 400 adjusts the driven wheel component 300 to an avoidance position in time, realizing autonomous crossing of obstacles 500 such as spacers, vibration dampers, and connecting pipes. This breaks through the limitation of existing devices being unable to cross obstacles, improves the sealing net efficiency, and ensures operational safety.

[0055] It should be noted that the drive wheel component 200 is mounted on the frame 100, enabling the device to move autonomously on the conductor 600. The driven wheel component 300 cooperates with the drive wheel component 200 to clamp and press the conductor 600. The obstacle avoidance mechanism 400 drives the driven wheel component 300 to move, allowing it to switch between a clamping position that presses the conductor 600 and a yielding position that avoids the obstacle 500, ensuring that the device's movement and obstacle-crossing functions are both realized. Under normal conditions, the drive wheel component 200 moves on the conductor 600, and the driven wheel component 300 cooperates with the drive wheel component 200 to clamp the conductor 600. When it is about to encounter an obstacle 500, the obstacle avoidance mechanism 400 drives the driven wheel component 300 to move to avoid the obstacle 500. At this time, the drive wheel component 200 continues to move until the driven wheel component 300 crosses the obstacle 500, and then the obstacle avoidance mechanism 400 drives the driven wheel component 300 to return to its original position and clamp the conductor 600.

[0056] In some embodiments, the drive wheel component 200 includes a power component and a drive wheel, the power component driving the drive wheel to rotate to achieve movement. Exemplarily, at least two drive wheel components 200 are spaced apart to ensure smooth movement. The driven wheel component 300 is adapted to the drive wheel component 200, thereby applying forces to opposite sides of the conductor 600 to achieve clamping and pressing. The pressing position and the avoidance position can be obtained by adaptively adjusting the drive mode of the obstacle avoidance mechanism 400 and the movement path of the driven wheel component 300, based on the actual structural dimensions of the sealing device, the specifications of the conductor 600 in the actual application site, and the structural dimensions of the obstacle 500 to be crossed, thereby ensuring the clamping effect on the conductor 600 and the compatibility with the obstacle 500.

[0057] Furthermore, the obstacle avoidance mechanism 400 drives the driven wheel component 300 to move, enabling the driven wheel component 300 to avoid the obstacle 500 at a preset time, ensuring that the device can smoothly overcome obstacles, and in normal operation, it can cooperate with the drive wheel component 200 to ensure the stability of the walking operation. For example, the obstacle avoidance mechanism 400 can drive the driven wheel component 300 through a transmission mechanism such as a linkage transmission structure, a crank-rocker transmission structure, a cam transmission structure, or a guide-limit transmission structure, so that the driven wheel component 300 can move according to a preset motion path to switch between a pressing position and an avoidance position.

[0058] Understandably, the drive wheel component 200 provides the power for movement, enabling the device to autonomously travel along the guide wire 600 and deploy the sealing net without manual traction, thus improving the efficiency of the sealing operation. The driven wheel component 300 works in conjunction with the drive wheel component 200 to press the guide wire 600, forming a stable clamp to ensure that the device does not slip or deviate while moving on the guide wire 600, ensuring operational stability. The obstacle avoidance mechanism 400 can drive the driven wheel component 300 to switch to an obstacle avoidance position, enabling autonomous crossing of obstacles 500 such as spacers and vibration dampers, overcoming the limitations of existing devices that cannot overcome obstacles. Through the coordinated operation of various components, the work process is simplified, manual intervention is reduced, the risks of working at heights are lowered, and the safety and continuity of the sealing operation are ensured.

[0059] Furthermore, a control device can be configured to control the drive wheel component 200 and the obstacle avoidance mechanism 400, enabling the device to move under preset commands and promptly drive the driven wheel component 300 to avoid obstacles 500. In some embodiments, the control device can be controlled by a technician to perform the operation. In other embodiments, sensors can be configured accordingly to form a control system with the control device to achieve automated operation. It is understood that in this embodiment, the device ensures stable movement on the conductor 600 through the cooperative clamping design of the drive wheel component 200 and the driven wheel component 300. Combined with the rapid connection with the insulating mesh and the automated movement and unfolding function, a complete and efficient operation link is formed, thus surpassing the operation effect of traditional manual operation and automated devices in related technologies.

[0060] The following will combine Figures 1 to 8 The sealing device disclosed in the embodiments of this application will be explained and described in detail.

[0061] It is understood that the sealing device in this embodiment of the application is mounted on the conductor 600 for operation. Therefore, in order to make the overall structure of the device simpler and to make the driven wheel component 300 switch between the pressing position of pressing the conductor 600 and the avoidance position of avoiding the obstacle 500 more accurate, the structural design of the obstacle avoidance mechanism 400 is the key to achieving the above effects.

[0062] In some embodiments of this application, reference is made to Figure 1 , Figures 6 to 8The obstacle avoidance mechanism 400 includes a drive assembly 410, a first slider 420, a second slider 430, a guide plate 440, and a rocker arm 450. A track groove 441 is formed on the guide plate 440, and the first slider 420 and the second slider 430 are slidably disposed in the track groove 441. A driven wheel 300 is disposed on the second slider 430. The drive assembly 410 is used to drive the first slider 420 to move. The first slider 420 is connected to the second slider 430 through the rocker arm 450, so that the second slider 430 can drive the driven wheel 300 to reach the pressing position or the avoidance position.

[0063] Understandably, the track groove 441 of the guide plate 440 provides sliding guidance for the first slider 420 and the second slider 430. The drive assembly 410 drives the first slider 420 to move along the track groove 441. The first slider 420 drives the second slider 430 to slide synchronously through the rocker arm component 450, thereby driving the driven wheel component 300 mounted on the second slider 430 to move. The degree of freedom of movement of the first slider 420 is affected by the drive assembly 410 and the track groove 441 of the guide plate 440. Therefore, the first slider 420 mainly plays the role of transmitting driving force. Based on this, through the coordinated arrangement of the rocker arm component 450, the first slider 420 and the second slider 430, the degree of freedom of movement of the second slider 430 is affected by the track groove 441 of the rocker arm component 450 and the guide plate 440, which makes the degree of freedom of movement of the driven wheel component 300 set in the second slider 430 higher and the movement path design more flexible. On the basis of simplifying the structural design of the drive component 410, the position design of the pressing position and the avoidance position is more flexible, ensuring that the pressing and avoidance actions are accurate and reliable, while improving obstacle crossing efficiency and flexibility.

[0064] In some specific embodiments, refer to Figures 6 to 8 The trajectory groove 441 includes a straight segment 4411 and a curved segment 4412. One end of the straight segment 4411 is connected to one end of the curved segment 4412. The pressing position is set at a position relatively close to the other end of the straight segment 4411, and the avoidance position is set at a position relatively close to the other end of the curved segment 4412.

[0065] It is understandable that the design of the straight segment 4411 ensures that the driven wheel component 300 can smoothly avoid obstacles 500 of various sizes, improving compatibility. The design of the curved segment 4412 ensures the flexibility of the avoidance position, thereby simplifying the overall design of the obstacle avoidance mechanism 400 and adapting to the space requirements of high-altitude wire 600 operations.

[0066] In some embodiments, the first slider 420 and the second slider 430 are sequentially arranged along the path from the pressing position to the avoidance position. The first slider 420 moves only on the straight segment 4411, while the second slider 430 can move on both the straight segment 4411 and the curved segment 4412. During the process of the driven wheel component 300 switching from the pressing position to the avoidance position, the drive component 410 first drives the first slider 420 and the second slider 430 to move synchronously on the straight segment 4411. Then, when the second slider 430 reaches the junction of the straight segment 4411 and the curved segment 4412, the first slider 420 continues to move downward under the driving force of the drive component 410. At this time, based on the guiding effect of the track groove 441 and the action of the rocker arm component 450, the second slider 430 continues to move along the curved segment 4412. By limiting the end position of the first slider 420's movement stroke on the straight segment 4411, the end point of the second slider 430's movement stroke is defined. This position corresponds to the position of the driven wheel component 300, which is the avoidance position. When the driven wheel component 300 switches from the avoidance position to the pressing position, the first slider 420 drives the second slider 430 to move through the rocker component 450 until the driven wheel component 300 contacts and presses the wire 600. This position corresponds to the pressing position. At this time, the drive component 410 can lock or continuously output power to ensure the effect of pressing the wire 600.

[0067] Exemplary, in some embodiments, reference is made to Figures 2 to 5 When in the clamping position, the axis of the driven wheel component 300 extends perpendicularly to the extension direction of the straight section 4411, ensuring that the clamping force is applied evenly to the conductor 600, enhancing the synergistic clamping effect with the drive wheel component 200, preventing the device from slipping or deviating when moving on the conductor 600, and ensuring operational stability.

[0068] Exemplary, in some embodiments, reference is made to Figures 2 to 5 When in the avoidance position, the axis of the driven wheel component 300 extends parallel to the direction of the straight section 4411. Understandably, guided by the trajectory of the curved section 4412, the driven wheel component 300 slides from its pressing position (where its axis is perpendicular to the straight section 4411) along the curved section 4412 to the avoidance position. Simultaneously, its axis adjusts to be parallel to the straight section 4411, thus reducing the space occupied by the driven wheel component 300 and smoothly avoiding various obstacles 500 such as spacers and vibration dampers. This eliminates the need for manual assistance in lifting the net or dismantling obstacles 500, reducing manpower input, avoiding secondary damage to the transmission lines during operation, significantly improving the efficiency of the netting operation, simplifying the control logic of the obstacle avoidance mechanism 400, reducing the device failure rate, and improving the safety of high-altitude operations.

[0069] In some specific embodiments, refer to Figures 6 to 8The drive assembly 410 includes a drive member 411 and a lead screw 412. The first slider 420 is connected to the lead screw 412. The drive member 411 drives the lead screw 412 to rotate, thereby moving the first slider 420. It can be understood that the first slider 420 and the lead screw 412 form a transmission connection. The drive member 411 drives the lead screw 412 to rotate, and the rotational motion of the lead screw 412 is converted into linear motion of the first slider 420, causing the first slider 420 to slide along the track groove 441. This, in turn, links the second slider 430 through the rocker arm component 450, enabling the driven wheel component 300 to switch between the pressing position and the obstacle avoidance position, providing stable power for obstacle avoidance.

[0070] In other embodiments, the drive component 410 may also be configured as a commonly used linear transmission component such as a slider linear module mechanism, a gear transmission lifting mechanism, or a telescopic lifting mechanism, so as to achieve the effect of driving the first slider 420 to move. This will not be described in further detail here. The specific structural composition of the drive component 410 can be adaptively adjusted according to actual usage requirements.

[0071] In some embodiments, the drive assembly 410 includes a guide shaft 413, which is arranged parallel to the lead screw 412. The guide shaft 413 is used to guide the movement of the first slider 420. The guide shaft 413 constrains and guides the movement direction of the first slider 420, so that the first slider 420 moves stably along a straight line, avoiding slider deflection and jamming, and ensuring smooth and reliable transmission and obstacle avoidance actions.

[0072] In some specific embodiments, refer to Figures 1 to 8 Multiple sets of driven wheel components 300 and obstacle avoidance mechanisms 400 are correspondingly provided, and multiple drive wheel components 200 are provided, with each drive wheel component 200 located between two adjacent driven wheel components 300. It can be understood that the multiple sets of driven wheel components 300 and drive wheel components 200 are staggered to achieve multi-point clamping, thereby increasing the contact area with the conductor 600, achieving a more stable grip and preventing slippage, ensuring reliable movement of the sealing device on the conductor 600, improving the stability of the device in high-altitude wind-induced vibration and swaying environments, and ensuring operational safety.

[0073] In some embodiments, the obstacle avoidance mechanism 400 drives three driven wheel components 300 and two drive wheel components 200 to clamp and press the conductor 600 together, ensuring that the device moves stably on the conductor 600 and providing structural support for the smooth implementation of the netting operation.

[0074] Understandably, based on the independent cooperation and multi-round collaborative work of multiple obstacle avoidance mechanisms 400, the control method of the obstacle avoidance mechanism 400 can be adaptively adjusted to meet the usage requirements of different working conditions.

[0075] In some embodiments, each obstacle avoidance mechanism 400 is used to drive each driven wheel component 300 to move, so that each driven wheel component 300 moves synchronously. It can be understood that by adopting the obstacle-crossing method of synchronous avoidance, the obstacle 500 can be crossed quickly and in one go, with high obstacle-crossing efficiency and stronger continuity of netting operation.

[0076] In some embodiments, each obstacle avoidance mechanism 400 is used to drive each driven wheel component 300 to move, so that each driven wheel component 300 moves in sequence. It can be understood that by adopting the obstacle-avoiding and obstacle-crossing method in sequence, it can be ensured that some driven wheel components 300 always hold the guide wire 600 tightly, so that the device will not lose support, ensuring stable walking and more reliable operation.

[0077] The second aspect of this application discloses a method of using a sealing device. This method of using the sealing device can be the same as the method of using the sealing device described in the first aspect of this application. (Refer to...) Figures 1 to 5 The method of using the sealing net device includes the following steps:

[0078] Adjust the driven wheel component 300 to the avoidance position;

[0079] The sealing device is attached to the conductor 600, so that the drive wheel component 200 can move on the conductor 600;

[0080] The obstacle avoidance mechanism 400 drives the driven wheel component 300 to move, so that the driven wheel component 300 reaches the pressing position, and the drive wheel component 200 travels on the guide wire 600;

[0081] When the driven wheel component 300 encounters an obstacle 500, the obstacle avoidance mechanism 400 drives the driven wheel component 300 to move, so that the driven wheel component 300 reaches the avoidance position;

[0082] The drive wheel component 200 continues to move until the driven wheel component 300 crosses the obstacle 500. The obstacle avoidance mechanism 400 then drives the driven wheel component 300 to move, causing the driven wheel component 300 to return to the pressed position.

[0083] Repeat the above steps to complete the net sealing operation.

[0084] It is understandable that the sealing device can be mounted on the conductor 600 by technicians or by drone.

[0085] In some embodiments, the active drive wheel component 200 of the device is hoisted onto the conductor 600 by a drone, eliminating the need for personnel to climb towers at heights or use aerial work platforms for installation. This solves the safety hazards and cumbersome installation problems associated with existing technologies that require personnel to go outside the lines for installation. After being hoisted, the device can quickly connect to the insulating mesh, autonomously moving and unfolding the mesh via the active drive wheel component 200, forming a complete automated operation chain of hoisting, clamping, connecting, moving, obstacle crossing, and mesh sealing, thus improving mesh sealing efficiency.

[0086] The sealing device of this application is described in detail below with reference to a specific embodiment. It should be noted that the following embodiment is merely an exemplary description and should not be construed as limiting the embodiments of this application.

[0087] See Figures 1 to 8 As shown, the netting device of this embodiment includes two drive wheel components 200 as active walking wheels, three driven wheel components 300 as driven wheels, three obstacle avoidance mechanisms 400, and an electrical control box containing a power supply and control device. It also includes a frame 100 and a drone hook mounted on the frame 100.

[0088] In practical use, the two active wheels of the sealing device can be mounted onto the conductor 600 via a drone. The obstacle avoidance mechanism 400 drives the three driven wheels to clamp and press the conductor 600 tightly. After the sealing device is installed, the insulating net is connected to the hook of the device. The sealing device can then cross the obstacle 500 to move to the designated location and complete the sealing operation.

[0089] In some specific embodiments, the obstacle avoidance mechanism 400 is the core component for completing automated barrier sealing operations in the barrier sealing device of this application. The obstacle avoidance mechanism 400 mainly consists of a motor (actually a drive component 411), a lead screw 412, a guide shaft 413, a guide plate 440, a first slider 420, a second slider 430, and a rocker arm component 450. The motor drives the lead screw 412, which in turn drives the first slider 420 and the second slider 430 within the guide plate 440 to move up and down within the track groove 441. The first slider 420 is the main moving component and is connected to the lead screw 412 via a thread, while the second slider 430 is not threaded to the lead screw 412. The rocker arm component 450 connects the first slider 420 and the second slider 430. When the second slider 430 descends to the bottom of the first slider 420's travel range, the lead screw 412 continues to rotate, driving the first slider 420 to continue moving downwards. Through the transmission of the rocker arm component 450 and the guidance of the track groove 441, the second slider 430 can continue to move and reach the avoidance position, thereby avoiding obstacles 500 on the conductor 600, such as the spacer bar of the vertical double-split conductor 600 or the anti-vibration hammer and splicing pipe on the single conductor 600. This not only overcomes the limitation of existing devices being unable to overcome obstacles, but also improves the efficiency of net sealing and ensures operational safety.

[0090] The drone according to the third aspect of this application includes: the net sealing device according to the first aspect of this application.

[0091] In some embodiments, the sealing device of this application is equipped with a hanging ring. The drone hooks onto the hanging ring to attach the sealing device to the drone, which then transports the sealing device and attaches it to the conductor 600 to perform the sealing operation. The drone-mounted design eliminates the need for personnel to climb towers, use aerial work platforms, or install on overhead lines. The drone can precisely attach the device's active wheels to the conductor 600, significantly reducing the risk of personnel working at heights, simplifying the installation process, and improving operational convenience.

[0092] It is easy to understand that the method of using the net sealing device in the second aspect embodiment of this application and the drone in the third aspect embodiment of this application both have the same technical effects as the net sealing device in the first aspect embodiment, and therefore will not be described again.

[0093] In the description of this application, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.

[0094] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, unless otherwise stated, "multiple" means two or more. It should be noted that the term "and / or" used herein is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, or B alone. Similarly, at least one of A or B can also represent: A alone, A and B simultaneously, or B alone.

[0095] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0096] In the foregoing description of this specification, references to terms such as "one embodiment," "another embodiment," or "some embodiments" indicate that a specific feature, structure, material, or characteristic described in connection with an embodiment or example is included in at least one embodiment or example of this application. In the description of this specification, specific features, structures, materials, or characteristics may be combined in any suitable manner in one or more embodiments or examples.
