Description

Technical Field

[0001] This application relates to the field of photovoltaic power plant technology, and more specifically, to a connecting bracket and a photovoltaic power plant. Background Technology

[0002] As a representative of renewable energy, photovoltaic (PV) power plants have become an important part of the modern energy structure due to their clean, environmentally friendly, and renewable advantages. However, PV panels are constantly exposed to the elements, easily accumulating dust and dirt, which affects power generation efficiency. To address this issue, PV cleaning robots have emerged. These robots utilize cleaning devices such as roller brushes to easily remove dirt from the surface of PV modules, ensuring their high-efficiency power generation.

[0003] During the process of the photovoltaic cleaning robot cleaning back and forth on the photovoltaic modules, it is necessary to set up connecting brackets such as parking spaces or reversing positions at the ends of the photovoltaic module array. Since the frames of photovoltaic modules have different specifications, the connecting brackets need to be customized based on the corresponding frame specifications, which makes it impossible to mass-produce the connecting brackets and the cost is high.

[0004] Therefore, how to improve the versatility of the connecting bracket to reduce manufacturing costs is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a connecting bracket to improve the versatility of the connecting bracket and reduce manufacturing costs;

[0006] Another objective of this application is to provide a cable tray assembly and a photovoltaic power station having the aforementioned connecting bracket.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] The first aspect of this application provides a connecting bracket, including a bracket body for connecting to the frame of a photovoltaic module and a first limiting part, a second limiting part and a third limiting part connected to the bracket body;

[0009] The support body includes a first support base and a first bending portion and a second bending portion disposed on the first support base and capable of bending. When the first bending portion is in a bent state, a first clamping groove is formed between it and the first limiting portion, clamping both sides of the frame in a first direction. When the second bending portion is in a bent state, a second clamping groove is formed between it and the second limiting portion, clamping both sides of the frame in a second direction.

[0010] A third clamping groove is formed between the first support base and the third limiting part, clamping the frame along a third direction. The first direction, the second direction, and the third direction are not parallel to each other, and the third direction is the arrangement direction of the upper and lower sides of the frame.

[0011] In one possible implementation, the support body includes a first support body and a second support body that are detachably connected;

[0012] The first bracket base, the first bent portion, and the second bent portion are all disposed on the first bracket body, which is used to be arranged on the lower side of the frame.

[0013] The third limiting part is disposed on the second bracket body, which is used to be arranged on the upper side of the frame.

[0014] In one possible implementation, the first support body is provided with a first connecting part, and the second support body is provided with a second connecting part, and the first connecting part and the second connecting part are snapped together and fixed along the third direction.

[0015] In one possible implementation, one of the first connecting part and the second connecting part is an adjusting buckle, and the other is an adjusting slot;

[0016] The adjusting buckle includes a buckle body, and the adjusting slot includes a slot body for engaging with the buckle body. Along the third direction, the number of at least one of the buckle body and the slot body is at least two.

[0017] In one possible implementation, both the first connecting portion and the second connecting portion are multiple portions arranged at intervals along the second direction.

[0018] In one possible implementation, the first bending portion includes a plurality of first bending teeth arranged along the second direction;

[0019] And / or,

[0020] The second bending portion includes a plurality of second bending teeth arranged along the first direction.

[0021] In one possible implementation, the first clamping slot is used to clamp a first frame body of the frame, and the second clamping slot is used to clamp a second frame body of the frame, wherein the first frame body and the second frame body are two frame bodies connected to the frame;

[0022] And / or,

[0023] The first direction, the second direction, and the third direction are perpendicular to each other.

[0024] In one possible implementation, both the first bending portion and the second bending portion are disposed at the first end of the first support body, and the third limiting portion is disposed at the first end of the second support body;

[0025] The second ends of the first support body and the second support body are provided with target body connecting parts, which are used to fix the target body.

[0026] In one possible implementation, the target body is a limiting member, which is used to limit the movement of the photovoltaic cleaning robot;

[0027] or,

[0028] The target body is a support member, which is used to support the first support body and the second support body;

[0029] or,

[0030] The target body is a bridge frame, which is a connector that connects the gaps between the photovoltaic modules to form the walking path of the photovoltaic cleaning robot.

[0031] The connecting bracket provided in this application has a first bent portion and a second bent portion on the first bracket base, both of which can be bent. When installing the connecting bracket onto the frame of a photovoltaic module, the first and second limiting portions can be first attached to the corresponding positions on the photovoltaic module, and then the first and second bent portions are bent, such that the first limiting portion and the first bent portion are clamped to both sides of the frame along a first direction, the second limiting portion and the second bent portion are clamped to both sides of the frame along a second direction, and the first bracket base and the third limiting portion are clamped to the upper and lower sides of the frame along a third direction. Since the first, second, and third directions are not parallel to each other, the clamping action with the frame of the photovoltaic module in three directions ensures the relative fixation of the connecting bracket and the photovoltaic module. The first and second bending portions can be bent along the width of the photovoltaic module frame in the first and second directions, so that a first clamping groove and a second clamping groove with corresponding width can be formed based on the corresponding frame specifications, so as to ensure that it can be used on photovoltaic modules of that specification, improve the versatility of the connecting bracket, and thereby reduce the manufacturing cost of the connecting bracket.

[0032] A second aspect of this application provides a photovoltaic power plant, including the connection bracket described above.

[0033] The photovoltaic power station provided in this application has all the technical effects of the aforementioned connection bracket, and will not be described in detail here. Attached Figure Description

[0060] This application discloses a connecting bracket to improve the versatility of the connecting bracket and reduce manufacturing costs;

[0061] This application also discloses a cable tray assembly and a photovoltaic power station having the above-mentioned connecting bracket.

[0062] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0063] like Figure 2 and Figure 3 As shown in the embodiment of this application, the connecting bracket includes a bracket body for connecting to the frame of the photovoltaic module 100, and a first limiting part 212, a second limiting part 230, and a third limiting part 224 connected to the bracket body. It should be noted that the first limiting part 212, the second limiting part 230, and the third limiting part 224 can be designed as an integral structure with the bracket body, or they can be fixed to the bracket body by a detachable fixing method, as long as the positional relationship with the bracket body remains unchanged.

[0064] like Figure 8 and 9 As shown, the support body includes a first support base portion 211 and a first bending portion 213 and a second bending portion 214 disposed on the first support base portion 211. The first bending portion 213 and the second bending portion 214 are bendable, that is, before the connecting support is installed on the photovoltaic module 100, the first bending portion 213 and the second bending portion 214 are in an unbent state, so as to facilitate the selection of the bending position according to the requirements to match the width of the frame of the photovoltaic module 100.

[0065] For example, when the first bent portion 213 and the second bent portion 214 are not bent, they can be in the same plane as the first support base portion 211. When bent, the bent portions of the first bent portion 213 and the second bent portion 214 can be at a certain angle to the first support base portion 211 depending on the bending angle. For example, they can be at a right angle. Of course, the angle can be greater than 90° or less than 90°. Those skilled in the art can choose the specific angle according to actual needs.

[0066] Please combine Figure 3 When the first bent portion 213 is in a bent state, a first clamping groove is formed between it and the first limiting portion 212, clamping both sides of the frame along the first direction. That is, the bent portion formed after the first bent portion 213 is bent forms a first clamping groove between it and the first limiting portion 212. The width of the first clamping groove can be controlled by controlling the position of the bending point of the first bent portion 213, so that the first limiting portion 212 and the bent portion 213 are respectively attached to both sides of the frame along the first direction.

[0067] When the second bent portion 214 is in a bent state, a second clamping groove is formed between it and the second limiting portion 230, clamping both sides of the frame along the second direction. That is, the bent portion formed after the second bent portion 214 is bent forms a second clamping groove between it and the second limiting portion 230. The width of the second clamping groove can be controlled by controlling the position of the bending point of the second bent portion 214, so that the second limiting portion 230 and the bent portion 214 are respectively attached to both sides of the frame along the second direction.

[0068] A third clamping groove is formed between the first support base portion 211 and the third limiting portion 224, clamping the frame along a third direction. The third direction refers to the arrangement direction of the upper and lower sides of the frame. The first support base portion 211 and the third limiting portion 224 are respectively clamped on the upper and lower sides of the frame. Since the distance between the upper and lower sides of the frame of photovoltaic modules 100 of different specifications is relatively uniform, even if the distance between the first support base portion 211 and the third limiting portion 224 is not adjustable, it can still meet the connection requirements of most photovoltaic modules 100.

[0069] The first, second, and third directions are not parallel to each other. The connecting bracket disclosed in this embodiment can limit the photovoltaic module 100 in the first, second, and third directions. Since the three directions are not parallel to each other, it can be ensured that the connection between the connecting bracket and the photovoltaic module 100 will not fail in any direction in space. Furthermore, the first, second, and third directions can be designed to be perpendicular to each other, so that the connecting bracket and the photovoltaic module 100 can be fixedly limited in three mutually perpendicular directions in space.

[0070] The connecting bracket disclosed in this application embodiment has a first bending portion 213 and a second bending portion 214 provided on the first bracket base portion 211. The first bending portion 213 and the second bending portion 214 can be bent. When installing the connecting bracket on the frame of the photovoltaic module 100, the first limiting portion 212 and the second limiting portion 230 can be attached to the corresponding positions of the photovoltaic module 100 firstly, and then the first bending portion 213 and the second bending portion 214 are bent, so that the first limiting portion 212 and the first bending portion 213 are clamped on both sides of the frame along the first direction, the second limiting portion 230 and the second bending portion 214 are clamped on both sides of the frame along the second direction, and the first bracket base portion 211 and the third limiting portion are clamped on the upper and lower sides of the frame along the third direction.

[0071] Since the first, second, and third directions are not parallel to each other, the clamping action between the connecting bracket and the frame of the photovoltaic module 100 in these three directions ensures the relative fixation of the connecting bracket and the photovoltaic module 100, preventing large relative movement within space and avoiding connection failure. The first bending portion 213 and the second bending portion 214 can be bent along the width of the frame of the photovoltaic module 100 in the first and second directions, so that a first clamping groove and a second clamping groove with corresponding width can be formed based on the corresponding frame specifications, ensuring that it can be used on photovoltaic modules 100 of that specification, improving the versatility of the connecting bracket, and thereby reducing the manufacturing cost of the connecting bracket.

[0072] like Figure 2 As shown in a specific embodiment of this application, the support body may include a first support body 210 and a second support body 220 that are detachably connected. By designing the first support body 210 and the second support body 220 to be detachably connected, the width of the third clamping groove can be adjusted according to the distance between the upper and lower sides of the frame of the photovoltaic module 100, further improving the versatility of the connection support.

[0073] like Figure 8 and Figure 9 As shown, the first support base portion 211, the first bent portion 213, and the second bent portion 214 are all disposed on the first support body 210, that is, the first support base portion 211, the first bent portion 213, and the second bent portion 214 are part of the first support body 210. The first support body 210 is used to be arranged on the lower side of the frame.

[0074] To improve the strength of the frame of the photovoltaic module 100, a corresponding flange is usually provided on the lower side of the photovoltaic module 100 to increase the width of the frame and ensure its strength, so as to provide safe and effective support for the power generation part of the photovoltaic module 100.

[0075] In this embodiment, the first support body 210 with the first bending portion 213 and the second bending portion 214 is arranged on the lower side of the photovoltaic module 100. This allows the adaptability of the first bending portion 213 and the second bending portion 214 to bend the first bending portion 213 and the second bending portion 214 according to the width of the bottom flange of the frame, so as to meet the installation requirements and make the first clamping groove and the second clamping groove clamp on the flange at the corresponding position of the frame.

[0076] The third limiting part 224 is disposed on the second bracket body 220, which is arranged on the upper side of the frame. This arrangement allows the distance between the third limiting part 224 and the first bracket base part 211 to be adjusted according to the distance between the upper and lower sides of the frame. In specific installation, the first bracket body 210 can be arranged on the lower side of the frame, and the second bracket body 220 can be arranged on the upper side of the frame. Then, the first bracket body 210 and the second bracket body 220 can be fixed by fasteners.

[0077] like Figure 8 and Figure 11 As shown, in order to ensure the stability of the first support body 210 and the second support body 220, in this embodiment, the first support body 210 is provided with a first connecting part 215, and the second support body 220 is provided with a second connecting part 223. The first connecting part 215 and the second connecting part 223 are snapped together and fixed in a third direction.

[0078] Furthermore, one of the first connecting part 215 and the second connecting part 223 is an adjusting buckle, and the other is an adjusting slot. For example, the first connecting part 215 is an adjusting buckle, and the second connecting part 223 is an adjusting slot; of course, the first connecting part 215 can also be designed as an adjusting slot, and the second connecting part 223 can be designed as an adjusting buckle. During installation, the adjusting buckle is inserted into the adjusting slot. If the distance between the upper and lower sides of the frame is small, the distance between the third limiting part 224 and the first bracket base part 211 needs to be small, and the adjusting buckle needs to be inserted into the adjusting slot to a deeper depth; if the distance between the upper and lower sides of the frame is large, the distance between the third limiting part 224 and the first bracket base part 211 needs to be large, and the adjusting buckle needs to be inserted into the adjusting slot to a shallower depth. In this embodiment, through the cooperation of the adjusting buckle and the adjusting slot, the stability of the first bracket body 210 and the second bracket body 220 after fixation can be ensured without affecting the adaptability of the connecting bracket, and the mutual deflection of the two can be prevented.

[0079] The adjusting buckle includes a buckle body and an adjusting slot including a slot body for engaging with the buckle body. Along the third direction, the number of at least one of the buckle body and the slot body is at least two. When the number of at least one of the buckle body and the slot body is more than two, the distance between the third limiting part 224 and the first support base part 211 can be adjusted by adjusting the engaging position of the buckle body and the slot body to match the distance between the upper and lower sides of the frame.

[0080] For example, there can be at least two snap-fit ​​bodies, while there is only one snap-fit ​​slot body. The snap-fit ​​slot body can selectively engage with one of the snap-fit ​​bodies. If the distance between the upper and lower sides of the frame is small, the distance between the third limiting part 224 and the first support base part 211 needs to be small, so the snap-fit ​​body positioned lower can be inserted into the snap-fit ​​slot body. If the distance between the upper and lower sides of the frame is large, the distance between the third limiting part 224 and the first support base part 211 needs to be large, so the snap-fit ​​body positioned higher can be inserted into the snap-fit ​​slot body. It should be noted that when there is only one snap-fit ​​slot body, the adjusting slot needs to be provided with clearance grooves at both ends along the third direction of the slot body to accommodate the snap-fit ​​body and ensure the sliding range of the snap-fit ​​body.

[0081] Alternatively, at least two slots can be designed, while only one latching body can be designed, allowing the latching body to selectively engage with one of the slots. If the distance between the top and bottom sides of the frame is small, the distance between the third limiting part 224 and the first support base part 211 needs to be small, allowing the latching body to be inserted into the upper slot. If the distance between the top and bottom sides of the frame is large, the distance between the third limiting part 224 and the first support base part 211 needs to be large, allowing the latching body to be inserted into the lower slot.

[0082] Alternatively, two or more snap-fit ​​bodies and slot bodies can be provided, with at least one snap-fit ​​body selectively engaging with at least one slot body. For example... Figure 14 As shown, if the distance between the top and bottom sides of the frame is small (i.e., the thickness of the photovoltaic module is small), then the distance between the third limiting part 224 and the first bracket base part 211 needs to be small. The buckle body can be inserted into the upper slot, meaning that adjusting the buckle requires inserting it into the adjustment slot to a deeper depth. Figure 15 As shown, if the distance between the top and bottom sides of the frame is large (i.e., the thickness of the photovoltaic module is large), then the distance between the third limiting part 224 and the first bracket base part 211 needs to be large. The buckle body can be inserted into the lower slot body, that is, to adjust the buckle, it needs to be inserted into the shallower depth of the adjustment slot.

[0083] like Figure 8 and Figure 11 As shown, the first connecting portion 215 is disposed on the first limiting portion 212. The first support base portion 211 and the first limiting portion 212 can be arranged perpendicularly to cover the two right-angled sides of the frame, respectively. The first support base portion 211 and the first limiting portion 212 can be an integral structure, and the first connecting portion 215 and the first limiting portion 212 can also be an integral structure. The first support body 210 can be processed by die stamping, reducing processing methods and significantly saving costs.

[0084] The second support body 220 may include a fourth limiting part 222. Both the first limiting part 212 and the fourth limiting part 222 are used to fit against the outer side of the frame, and a second connecting part 223 is disposed on the fourth limiting part 222. After the first connecting part 215 and the second connecting part 223 are inserted and engaged, the fourth limiting part 222 and the first limiting part 212 are on the same plane. The fourth limiting part 222 and the third limiting part 224 may be arranged vertically to cover the two right-angled sides of the frame, respectively. The fourth limiting part 222 and the third limiting part 224 may be an integral structure. The second support body 220 can be processed by die stamping, reducing processing methods and significantly saving costs.

[0085] To further improve the fixing and limiting effect, the first connecting part 215 and the second connecting part 223 can both be multiple parts arranged at intervals along the second direction. The second direction is the extension direction of the connecting bracket, and can also be understood as the arrangement direction between the two sets of photovoltaic modules to be connected.

[0086] like Figure 8 and Figure 9 As shown, the first bending portion 213 includes a plurality of first bending teeth arranged along a second direction. The second bending portion 214 may also include a plurality of second bending teeth arranged along a first direction. Each first bending tooth and each second bending tooth may also be processed by a die stamping process. In this embodiment, both the first bending portion 213 and the second bending portion 214 are configured to include a plurality of bending teeth. Since the first bending teeth and each second bending tooth have a smaller width dimension, they are easier to bend, which facilitates bending the first bending portion 213 and the second bending portion 214 during installation.

[0087] Furthermore, since both the first bending portion 213 and the second bending portion 214 are configured to include multiple bending teeth, the number of bending teeth (first bending teeth and each of the second bending teeth) required for bending can be selected according to needs. In particular, the number of first bending teeth is important.

[0088] like Figure 12 and Figure 13 As shown, the first clamping groove is used to clamp the first frame body 101 of the frame, and the second clamping groove is used to clamp the second frame body 102 of the frame. The first frame body 101 and the second frame body 102 are two frame bodies connected to the frame, that is, the first frame body 101 and the second frame body 102 are two frame bodies that are perpendicular to each other.

[0089] like Figure 12As shown, when the flange widths of the first frame body 101 and the second frame body 102 are large, when installing the connecting bracket on the frame of the photovoltaic module 100, the first limiting part 212 and the second limiting part 230 can be attached to the corresponding positions of the photovoltaic module 100 firstly, and then all the second bending teeth can be bent according to the first flange width of the first frame body 101 to achieve the limiting fixation between the connecting bracket and the first frame body 101; then the first bending teeth that can correspond to the second frame body 102 can be bent (due to the different first flange widths, the number of first bending teeth corresponding to the second frame body 102 is different. The larger the first flange width, the more first bending teeth corresponding to the first frame body 101 there are, and the first bending teeth corresponding to the first frame body 101 cannot be limited and fixed to the second frame body 102 by bending) to achieve the limiting fixation between the connecting bracket and the second frame body 102.

[0090] When the flange width of the first frame body 101 and the second frame body 102 is large, the bending position of the first bending tooth and the second bending tooth is closer to their tooth root.

[0091] like Figure 13 As shown, when the flange widths of the first frame body 101 and the second frame body 102 are small, the installation process of the connecting bracket is the same as the above installation process, and will not be repeated. When the flange widths of the first frame body 101 and the second frame body 102 are small, the bending positions of the first bending tooth and the second bending tooth are farther from their tooth roots.

[0092] Any two adjacent first bending teeth are separated by a first bending tooth groove, and any two adjacent second bending teeth are separated by a second bending tooth groove. It should be noted that the lengths of the first and second bending teeth can be equal, unequal, or partially equal and partially unequal; the widths of the first and second bending tooth grooves can be equal, unequal, or partially equal and partially unequal; the number of first and second bending teeth can be equal or unequal.

[0093] In addition, the width of the first bending tooth groove and the width of the second bending tooth groove do not need to be too large, as long as they can separate the bending teeth and allow each bending tooth to be bent individually.

[0094] In one specific embodiment of this application, the first bending portion 213 and the second bending portion 214 are both disposed at the first end of the first support body 210, and the third limiting portion 224 is disposed at the first end of the second support body 220. That is, the first end of the connecting bracket is connected to the frame of the photovoltaic module.

[0095] The second support body 220 has a second support base 221 parallel to the first support base 211 of the first support body 210. The second support base 221 is used to support the walking wheels of the photovoltaic cleaning robot. The second support base 221 can be located on the same plane as the third limiting part 224, but it needs to have a larger width than the third limiting part 224 to facilitate the passage of the photovoltaic cleaning robot.

[0096] The second ends of the first support body 210 and the second support body 220 are provided with target body connecting portions for fixing the target body. The target body connecting portion may include a first mounting hole 2111 formed on the first support body 210, which may be formed on the first support base portion 211. The target body connecting portion may also include a second mounting hole 2211 formed on the second support body 220, which may be formed on the second support base portion 221. The target body connecting portion may also include a fastening bolt 260. The target body is clamped between the first support body 210 and the second support body 220, and after the first mounting hole 2111 and the second mounting hole 2211 are aligned with the fixing holes on the target body, the fastening bolt 260 is inserted to achieve locking.

[0097] When the first support body 210 and the second support body 220 are changed, the distance between the first support base 211 and the second support base 221 can be matched by padding the target body with a corresponding thickness or stacking a corresponding number of pads, thereby reducing the gap between the target body and the first support base 211 and the second support base 221.

[0098] like Figure 4 and Figure 5 As shown, the target body can be a limiting member 250, which is used to limit the movement of the photovoltaic cleaning robot. For the photovoltaic modules at the tail end, the limiting member 250 can be set to restrict the extreme position of the photovoltaic cleaning robot and prevent it from falling off the photovoltaic modules. When the connecting bracket is equipped with the limiting member 250, the connecting bracket is a reversing bracket, and the photovoltaic cleaning robot can change its walking direction at this point.

[0099] like Figure 6 and Figure 7 As shown, the target body can also be a support member 270. The support member 270 is used to support between the first support body 210 and the second support body 220 to support the second end of the connecting bracket and prevent the second end from deforming.

[0100] The target body can also be a bridge frame, which is a connector that connects the photovoltaic modules 100 to form the walking path of the photovoltaic cleaning robot. That is, the second end of the connecting bracket can be connected to the corresponding position of the bridge frame to realize the connection between the bridge frame and the photovoltaic modules.

[0101] like Figure 2 As shown, the second limiting part 230 is detachably fixed between the first support body 210 and the second support body 220. The second limiting part 230 may include a sleeve and a limiting plate disposed on the sleeve. After the second limiting part 230 is disposed between the first support body 210 and the second support body 220, it can be locked by fasteners 240 passing through the first support body 210, the sleeve, and the second support body 220 respectively. It should be noted that a third mounting hole 2112 for the fastener 240 to pass through can be provided on the first support base part 211, and a fourth mounting hole 2212 for the fastener 240 to pass through can be provided on the second support base part 221. In this embodiment, the second limiting part 230 is designed as a detachable connection structure, which makes it easier to install the connecting support.

[0102] Both the first support body 210 and the second support body 220 can be made of galvanized magnesium-aluminum sheet, reducing the types of materials used in the connecting bracket and ensuring both corrosion resistance and strength. Furthermore, except for fasteners, all components of the connecting bracket can be made of galvanized magnesium-aluminum sheet.

[0103] like Figure 1 As shown in the illustration, this application also discloses a photovoltaic power station, which includes the connecting brackets as described above. The edges of the photovoltaic modules can be connected to the corresponding bridge frame via three connecting brackets. The three connecting brackets can be a first connecting bracket 200a located on the first side of the photovoltaic module, a second connecting bracket 200c located on the second side of the photovoltaic module, and a third connecting bracket 200b located on the middle side of the photovoltaic module. It should be noted that the scenario with three connecting brackets is suitable for photovoltaic cleaning robots with three sets of wheels; if the photovoltaic cleaning robot has two sets of wheels, then the third connecting bracket 200b is not required. For photovoltaic modules at the tail end of the discharge line, the connecting brackets can serve as reversing brackets, allowing the photovoltaic cleaning robot to change its walking direction at this location.

[0104] As indicated in this application and claims, unless the context clearly indicates otherwise, the words "a," "an," "a," and / or "the" are not specifically singular and may include the plural. Generally, the terms "comprising" and "including" only indicate the inclusion of expressly identified steps and elements, which do not constitute an exclusive list, and the method or apparatus may also include other steps or elements. An element defined by the phrase "comprising an..." does not exclude the presence of other identical elements in the process, method, product, or apparatus that includes the element.

[0105] In the description of this application, unless otherwise expressly defined, terms such as "setup," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this application in conjunction with the specific content of the technical solution.

[0106] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0107] This document uses specific examples to illustrate the principles and implementation methods of this application. The descriptions of the embodiments above are only for the purpose of helping to understand the method and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of the claims of this application.
