DETAILED DESCRIPTION

[0016] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the present application.

[0017] The embodiment of the present application provides a power cover plate matched with a coupling structure, a type-1 cover plate, a type-2 cover plate and a type-3 cover plate; The right side of the type-1 cover plate is provided with a first locking structure; The left side of the type-2 cover plate is provided with a second locking structure coupled and locked with the first locking structure; The right side of the type-2 cover plate is provided with a third locking structure; The left side of the type-3 cover plate is provided with a fourth locking structure coupled and locked with the third locking structure; The top of the type-3 cover plate is provided with a threaded hole with a depth less than the thickness of the cover plate.

[0018] In the specific implementation of the embodiment, refer to Figure 1 Fig. 1 is a structural schematic diagram of a power cover plate matched with a coupling structure provided by the embodiment of the present application, comprising a type-1 cover plate, a type-2 cover plate and a type-3 cover plate; By providing specific locking structures on different types of cover plates, the mutual restriction and locking between the multiple cover plates are realized by using the coupling and locking relationship between the structures. The first locking structure on the right side of the type-1 cover plate is coupled with the second locking structure on the left side of the type-2 cover plate, and the third locking structure on the right side of the type-2 cover plate is coupled with the fourth locking structure on the left side of the type-3 cover plate, forming a closely connected whole.

[0019] Install the type-1 cover plate according to the designed position, and ensure that the first locking structure on the right side thereof faces the correct direction and corresponds to the installation position of the type-2 cover plate. Install the type-2 cover plate beside the type-1 cover plate, so that the second locking structure on the left side of the type-2 cover plate is accurately butted and coupled with the first locking structure of the type-1 cover plate, and the preliminary connection is completed. Then, adjust the third locking structure on the right side of the type-2 cover plate to match the installation position of the type-3 cover plate. Install the type-3 cover plate, so that the fourth locking structure on the left side thereof is coupled and locked with the third locking structure of the type-2 cover plate. Thus, the three cover plates are closely connected through the locking structures on the sides.

[0020] Only the threaded hole with a depth less than the thickness of the cover plate provided on the top of the type-3 cover plate can be used to cooperate with a special anti-theft hook, further enhancing the anti-theft performance.

[0021] It should be noted that the type-1 cover plate, the type-2 cover plate and the type-3 cover plate shown in Figure 1 are only a preferred embodiment, and in other embodiments, the locking structures of the type-1 cover plate, the type-2 cover plate and the type-3 cover plate can adopt other structures.

[0022] It should be noted that the specific locking structures between the cover plates can be selected when applied. For example: The hook type locking structure is provided with a hook protruding outward on the right side of the first cover plate as a first locking structure, which is similar to an inverted "L" type, and the end of the hook has a certain curvature to facilitate clamping. The second locking structure is a matching slot on the left side of the second cover plate, which is matched with the hook. The depth and width of the slot are adapted to the size of the hook. During installation, the hook of the first cover plate is aligned with the slot of the second cover plate, and the hook is smoothly inserted into the slot to achieve close fitting and limit the relative displacement of the two cover plates in the horizontal direction. Similarly, the hook is provided on the right side of the second cover plate as a third locking structure, and the slot is provided on the left side of the third cover plate as a fourth locking structure to complete the connection between the subsequent cover plates.

[0023] The magnetic type locking structure is provided with a strong magnet embedded on the right side of the first cover plate as a first locking structure, and an iron sheet or a magnetic material with opposite polarity and capable of close adsorption is installed on the left side of the second cover plate as a second locking structure. According to the principle of magnetic attraction between opposite poles, when the two cover plates are close to each other, they are automatically adsorbed and attached, generating a large adsorption force to stably connect the two cover plates. For the right side of the second cover plate and the left side of the third cover plate, similar magnet and iron sheet (or magnetic material) combination is also adopted as the third and fourth locking structures, respectively, to realize the magnetic attraction locking between multiple cover plates. This structure is easy to install and has a certain degree of concealment, and is not easy to be damaged.

[0024] The mortise and tenon type locking structure is provided with a protruding tenon on the right side of the first cover plate as a first locking structure, which can be rectangular, trapezoidal or other shapes, and has a certain length and width. The second locking structure is a mortise eye on the left side of the second cover plate, which is matched with the tenon. The internal size of the mortise eye precisely fits the tenon to ensure close fitting after insertion without obvious shaking. The mortise and tenon structure relies on its shape and size to achieve mechanical connection, which can effectively resist external force pulling in the horizontal and vertical directions. Similarly, the tenon is provided on the right side of the second cover plate as a third locking structure, and the mortise eye is provided on the left side of the third cover plate as a fourth locking structure, and so on to complete the connection of the entire cover plate system. The stability of the mortise and tenon structure enhances the anti-theft performance.

[0025] Through the mutual coupling of the locking structures between multiple cover plates, it becomes extremely difficult for any cover plate to be removed alone. The depth of the threaded hole on the top of the third cover plate is less than the thickness of the cover plate, making it difficult for ordinary tools to directly remove the third cover plate. Due to the depth limitation, conventional removal methods such as socket wrench cannot be used normally, further enhancing the anti-theft performance.

[0026] In another embodiment provided by the present application, when the number of second cover plates exceeds one, the first locking structure is the same as the third locking structure, and the second locking structure is the same as the fourth locking structure.

[0027] In the embodiment, when the number of the second type of cover plates exceeds one, the first locking structure is the same as the third locking structure, and the second locking structure is the same as the fourth locking structure. Since the first locking structure is the same as the third locking structure, and the second locking structure is the same as the fourth locking structure, the plurality of second type of cover plates can be sequentially and smoothly connected.

[0028] Specifically, the first locking structure on the right side of the first type of cover plate can be coupled and locked with the second locking structure on the left side of the first second type of cover plate, and the third locking structure on the right side of the first second type of cover plate can be coupled and locked with the second locking structure on the left side of the second second type of cover plate, and so on, so as to realize the continuous connection of the plurality of second type of cover plates. The third locking structure on the right side of the last second type of cover plate is coupled and locked with the fourth locking structure on the left side of the third type of cover plate, forming a complete connection whole. At the same time, the threaded hole with a depth smaller than the thickness of the cover plate on the top of the third type of cover plate is still matched, enhancing the overall anti-theft performance.

[0029] Since the first locking structure is the same as the third locking structure, and the second locking structure is the same as the fourth locking structure, the connection mode of the plurality of second type of cover plates is unified, and it is not necessary to distinguish the locking structures in different positions, greatly simplifying the installation process, improving the installation efficiency, and reducing the probability of errors due to structural confusion in the installation process. This structure design makes it possible to flexibly increase the number of second type of cover plates according to actual needs, and only needs to be installed in sequence according to the unified connection mode, without the need for additional adjustment of the locking structure, enhancing the applicability and expansibility of the scheme in different scenarios. The unified locking structure makes the maintenance work more convenient. When a second type of cover plate needs to be replaced, since the locking structures are the same, the replacement process is simple and easy to operate, without the need for special tools or complex operations, reducing the time and cost of maintenance.

[0030] Since the shape of the plurality of cover plates is just matched with the shape of the cover well, the transverse movement between the cover plates is limited, and therefore, the longitudinal movement of the cover plates can be limited by the stepped surface, achieving the purpose of limiting the movement of the cover plates. As a whole, the cover plates will be difficult to move as a whole.

[0031] It should be noted that the left side of the first type of cover plate or the right side of the third type of cover plate can also be provided with a locking structure coupled with the cover well, to ensure that the whole cover plate is locked on the cover well.

[0032] The plurality of cover plates are matched with each other, and the weight of the plurality of cover plates is concentrated together, so that the originally independent cover plates become a whole. The system achieves the purpose of turning zero into one, further overcomes the disadvantage of light weight of the traditional cover plate, and achieves a certain anti-theft function. By changing the type of the manhole, the anti-theft performance of the system is further improved. In the whole, the 1-type cover plate and the 2-type cover plate are not designed with a traditional manhole, and the two types of cover plates cannot be opened by simply pulling like the traditional cover plate. In the whole, the 3-type cover plate (opening plate) is designed with a manhole, and can be opened only under the condition that a specific threaded ring is used by the operating personnel, so as to achieve the purpose of being unable to open the cover plate without tools.

[0033] In another embodiment provided by the present application, the right side of the 1-type cover plate is designed as a ladder with a narrow upper part and a wide lower part, and a concave surface with a first width value and a first thickness value is arranged on the upper part of the right side to form the first locking structure; The left side of the 2-type cover plate is designed as a ladder with a wide upper part and a narrow lower part, and a convex projection with a width not greater than the first width value and a thickness not greater than the first thickness value is arranged on the upper part of the left side to form the second locking structure; The right side of the 2-type cover plate is designed as a ladder with a narrow upper part and a wide lower part, and a concave surface with a second width value and a second thickness value is arranged on the upper part of the right side to form the third locking structure; The left side of the 3-type cover plate is designed as a ladder with a wide upper part and a narrow lower part, and a convex projection with a width not greater than the second width value and a thickness not greater than the second thickness value is arranged on the upper part of the left side to form the fourth locking structure.

[0034] In the specific implementation of the present embodiment, the coupling and locking of the cover plates of different types are achieved through the precise matching of the stepped concave-convex structures, and the stable connection is formed by the complementarity of the structural forms.

[0035] The right side of the 1-type cover plate is designed as a ladder with a narrow upper part and a wide lower part, and a concave surface with a first width value and a first thickness value is arranged on the upper part of the right side to form the first locking structure; The left side of the 2-type cover plate is designed as a ladder with a wide upper part and a narrow lower part, and a convex projection with a width not greater than the first width value and a thickness not greater than the first thickness value is arranged on the upper part of the left side to form the second locking structure, and the two can be tightly engaged through concave-convex matching to limit the relative displacement in the horizontal and vertical directions.

[0036] Meanwhile, the right side of the 2-type cover plate is designed as a ladder with a narrow upper part and a wide lower part, and a concave surface with a second width value and a second thickness value is arranged on the upper part of the right side to form the third locking structure, and the left side of the 3-type cover plate is designed as a ladder with a wide upper part and a narrow lower part, and a convex projection with a width not greater than the second width value and a thickness not greater than the second thickness value is arranged on the upper part of the left side to form the fourth locking structure, and the locking is also completed through concave-convex matching.

[0037] When the number of the 2-type cover plates is more than one, the first width value is equal to the first width value; and the first thickness value is equal to the second thickness value.

[0038] Since the first locking structure and the third locking structure are both upper-narrow lower-wide stepped concaves (only the size may be different), the second locking structure and the fourth locking structure are both upper-wide lower-narrow stepped convexes (the size is matched with the corresponding concave), the sequential connection of multiple 2-type cover plates can be realized, and finally a complete locking whole from 1-type to multiple 2-type and then to 3-type is formed, in combination with the threaded hole design at the top of the 3-type cover plate, the anti-theft performance is further strengthened.

[0039] Referring to Figure 2 is a structural schematic diagram of a 1-type cover plate provided by an embodiment of the present application, referring to Figure 3 is a structural schematic diagram of a 2-type cover plate provided by an embodiment of the present application; referring to Figure 4 is a structural schematic diagram of a 3-type cover plate provided by an embodiment of the present application. Figure 2 GB1 in the figure is a 1-type cover plate, Figure 3 GB2 in the figure is a 2-type cover plate, Figure 4 GB3 in the figure is a 3-type cover plate.

[0040] The 1-type cover plate keeps the main body structure of 1000mm (long) x 500mm (wide) x 50mm (thick) unchanged, a "concave" surface is formed by extending the right edge of the cover plate outward by 30mm, and the thickness of the concave surface is 25mm.

[0041] The 2-type cover plate keeps the main body structure of 1000mm (long) x 500mm (wide) x 50mm (thick) unchanged, a "concave" surface is formed by extending the right edge of the cover plate outward by 30mm, and a convex is formed by collecting the left edge of the cover plate inward by 30mm, and the thickness of the concave surface is 25mm.

[0042] The 3-type cover plate keeps the main body structure of 1000mm (long) x 500mm (wide) x 50mm (thick) unchanged, a convex is formed by collecting the left edge of the cover plate inward by 30mm, and the thickness of the convex is 25mm.

[0043] The installation and cooperation instruction of the power cover plate cooperation system is as follows: the construction personnel first place the type 1 cover plate (starting plate), and make the type 1 cover plate abut against the wall of the well circle, then the construction personnel place a plurality of type 2 cover plates (cooperation plates), and need to ensure that the convex surface extension of the type 2 cover plate is closely cooperated with the concave surface extension of the type 1 cover plate, the concave surface extension of the type 2 cover plate is cooperated with the convex surface extension of another type 2 cover plate, and the cooperation between the type 2 cover plates is repeated above operation steps. The last plate is placed by the construction personnel, that is, the type 3 cover plate (opening plate), the convex surface extension of the type 3 cover plate is cooperated with the concave surface of the type 2 cover plate, and the type 3 cover plate is closely cooperated with the wall of the well circle. The convex surface and the concave surface between the three types of cover plates are closely cooperated with each other, and several separate cover plates are integrated into a unit. The cover plate cannot be easily lifted, and a locking effect is achieved.

[0044] The design of the stepped concave-convex structure enables mechanical engagement when the cover plates are connected, and the stepped shape of the upper narrow lower wide and the upper wide lower narrow can effectively resist the vertical pulling and the horizontal prying. Compared with the ordinary plane connection, the contact area is larger and the stress is more uniform, which greatly improves the anti-damage ability of the overall structure. The size limitation of the concave surface and the convex (the convex size is not greater than the corresponding concave surface) ensures the accurate alignment during connection, and the close cooperation can be achieved without complex adjustment during installation, which reduces the installation error. At the same time, the guiding effect of the stepped structure makes the installation more smooth, and improves the construction efficiency. Good scalability and compatibility: when the number of type 2 cover plates needs to be increased, the uniform stepped concave-convex structure ensures the consistency of the connection, and the length of the cover plate can be flexibly expanded and the different installation scenes can be compatible by adjusting the size of the concave surface and the convex according to the actual demand.

[0045] In another embodiment provided by the present application, the right side surface of the type 1 cover plate is designed as an inclined surface with the upper narrow lower wide and the first angle, constituting the first locking structure; The left side surface of the type 2 cover plate is designed as an inclined surface with the upper wide lower narrow and the first angle, constituting the second locking structure; The right side surface of the type 2 cover plate is designed as an inclined surface with the upper narrow lower wide and the second angle, constituting the third locking structure; The left side surface of the type 3 cover plate is designed as an inclined surface with the upper wide lower narrow and the second angle, constituting the fourth locking structure.

[0046] In the specific implementation of the present embodiment, referring to Figure 5 Another structure diagram of the power cover plate cooperating with the coupling structure provided by the embodiment of the present application; The coupling and locking of the cover plates of different types are realized by the complementary cooperation of the inclined surfaces with different slopes, and the stable connection is formed by the fitting characteristics of the inclined surfaces.

[0047] The right side of the 1st cover plate is a slope with a first angle, which is narrow at the top and wide at the bottom, serving as a first locking structure; the left side of the 2nd cover plate is a slope with the same first angle, which is wide at the top and narrow at the bottom, serving as a second locking structure, and the slopes of the two are consistent, which can be closely fitted and limit the relative displacement in the horizontal and vertical directions through the interaction between the slopes.

[0048] Meanwhile, the right side of the 2nd cover plate is a slope with a second angle, which is narrow at the top and wide at the bottom, serving as a third locking structure; the left side of the 3rd cover plate is a slope with the second angle, which is wide at the top and narrow at the bottom, serving as a fourth locking structure, and the same slope makes the two slopes also accurately fit and lock.

[0049] When the number of 2nd cover plates exceeds one, the first angle is equal to the second angle.

[0050] Since the shape of the assembled cover plates is exactly matched with the shape of the cover plate well, the transverse movement between the cover plates is limited, and therefore, the longitudinal movement of the cover plates can be limited through the slope, achieving the purpose of limiting the movement of the cover plates, and the cover plates as a whole will be difficult to move as a whole.

[0051] Since the first locking structure and the third locking structure are slopes with different slopes but are both narrow at the top and wide at the bottom, and the second locking structure and the fourth locking structure are both slopes wide at the top and narrow at the bottom (adapted to the corresponding slope), the connection of multiple 2nd cover plates can be realized, and finally a complete locking whole from the 1st to the multiple 2nd and then to the 3rd is formed, and combined with the threaded hole design at the top of the 3rd cover plate, the anti-theft performance is further strengthened.

[0052] The slope with the same slope has a good guiding effect, and during installation, it is not necessary to accurately align, but only to roughly fit the slope, which can be automatically adjusted to a perfect fitting state under the action of pressure, reducing the installation difficulty and error and improving the construction efficiency. The physical locking of the slope structure makes it difficult to pry with simple tools, and the existence of the slope increases the resistance when prying. The continuous connection of multiple cover plates forms a chain protection, further improving the anti-theft level.

[0053] In another embodiment provided by the present application, the length of the 1st cover plate, the 2nd cover plate and the 3rd cover plate are the same; The width of the 1st cover plate, the 2nd cover plate and the 3rd cover plate are the same; The height of the 1st cover plate, the 2nd cover plate and the 3rd cover plate are the same.

[0054] In the specific implementation of the present embodiment, the 1st cover plate, the 2nd cover plate and the 3rd cover plate are completely the same in length, width and height. This means that the outer dimensions of each type of cover plate are completely consistent, and only the locking structure (slope and form) of the side surface is different.

[0055] The three cover plates keep the main body structure unchanged with a length of 1000 mm, a width of 500 mm and a thickness of 50 mm.

[0056] The unified length, width and height enable the connected cover plates to form a whole structure with regular appearance and smooth transition. The adjacent cover plates do not have height difference or size misplacement at the edges and surfaces, reducing the structural weak points caused by inconsistent sizes and improving the overall load bearing capacity and deformation resistance. The same size reduces the production cost.

[0057] In another embodiment provided by the application, a pull hook with a thread at one end and a pull ring at the other end is further included. The thread hole is matched with the thread.

[0058] In the specific implementation of the embodiment, based on the size-unified bevel locking structure cover plate scheme, a pull hook with a thread at one end and a pull ring at the other end is newly added, and the thread of the pull hook is matched with the thread hole at the top of the 3-type cover plate. This design further improves the function of the cover plate system, which not only retains the stable connection of the original cover plates through the unified size and bevel locking structure, but also provides convenience for the installation, disassembly and maintenance of the cover plates by matching the pull hook with the thread hole, without affecting the overall anti-theft performance.

[0059] From the connection and operation logic, the cover plates of different types are still tightly connected and form a stable whole by relying on the unified length, width and height and the bevel locking structure on the side. The function of the pull hook is mainly reflected in the scene where the 3-type cover plate needs to be moved or adjusted. When the 3-type cover plate needs to be installed or disassembled, the thread end of the pull hook is screwed into the thread hole at the top of the 3-type cover plate, and the pull ring is used to exert a pulling force or a pushing force, which is convenient for operation. In daily use, the pull hook can be removed, and the thread hole at the top of the 3-type cover plate can still cooperate with the special anti-theft bolt to play an anti-theft role, realizing the combination of functionality and safety.

[0060] The setting of the pull hook provides a convenient stress point for the installation, disassembly and movement of the 3-type cover plate. During installation, the position of the 3-type cover plate can be easily adjusted through the pull ring to make it precisely docked with the adjacent cover plate; during maintenance or disassembly, the 3-type cover plate can be separated from other cover plates more labor-savingly by using the pull hook, which reduces the operation difficulty, especially in the case of small space or heavy weight of the cover plate, the advantage is more obvious. The pull hook is only used when operation is needed, which ensures the safety of the cover plate system.

[0061] In another embodiment provided by the application, the 1-type cover plate, the 2-type cover plate and the 3-type cover plate are all composed of unsaturated resin matrix mixed with high-strength aggregate.

[0062] In the specific implementation of the embodiment, the type 1 cover plate, the type 2 cover plate and the type 3 cover plate are all composed of an unsaturated resin matrix mixed with high-strength aggregate.

[0063] The unsaturated resin matrix has good formability and adhesion, and can firmly combine the high-strength aggregate (such as quartz sand, basalt particles, etc.) to form a composite cover plate with certain toughness and high strength. The material properties are compatible with the uniform size, bevel locking structure and pull hook design of each cover plate: On the one hand, the high strength of the material ensures that the bevel locking structure can withstand a large force without deforming or being damaged when coupled and locked, ensuring the stability of the connection. On the other hand, the corrosion resistance and aging resistance of the unsaturated resin can prolong the service life of the cover plate and adapt to different use environments. At the same time, the cooperation of the pull hook and the threaded hole of the type 3 cover plate can safely realize the movement and adjustment of the cover plate under the support of the material strength, and will not cause damage to the threaded hole or the connection part of the pull hook due to insufficient material strength.

[0064] Another embodiment of the present application provides a method for using a coupling structure matched power cover plate, which is applied to any of the coupling structure matched power cover plates in the above embodiments, and refers to Figure 6 is a flowchart of a method for using a coupling structure matched power cover plate according to an embodiment of the present application. The method comprises the following steps: Step S1, installing the type 1 cover plate; Step S2, coupling and locking the second locking structure on the left side of the type 2 cover plate with the first locking structure on the right side of the type 1 cover plate, and installing the type 2 cover plate; Step S3, coupling and locking the fourth locking structure on the left side of the type 3 cover plate with the third locking structure on the right side of the type 2 cover plate, and installing the type 3 cover plate.

[0065] In the specific implementation of the embodiment, the complementarity and uniformity of the bevel locking structures on the sides of the cover plates of different types make each installation step precise and stable. The type 1 cover plate serves as the starting basis and provides a mounting reference for the type 2 cover plate. The type 2 cover plate is coupled with the right side bevel of the type 1 cover plate through the left side bevel, which not only fixes itself but also provides a connection basis for the type 3 cover plate. The type 3 cover plate is coupled with the right side bevel of the type 2 cover plate through the left side bevel to complete the assembly of the entire system.

[0066] First, place the type 1 cover plate in the predetermined installation position to ensure stable placement and accurate position. Since the sizes of the cover plates are uniform, the installation position of the type 1 cover plate will directly determine the installation accuracy of the subsequent cover plates, so it needs to be carefully adjusted to ensure that the first locking structure on the right side is facing the correct installation direction, preparing for connection with the type 2 cover plate. During installation, a level or other tool can be used to check the levelness of the type 1 cover plate to ensure stable placement. Pick up the Type 2 cover plate, and align the second locking structure on the left side with the first locking structure on the right side of the Type 1 cover plate. Because the two locking structures are adapted and the length, width and height of each cover plate are consistent, the left side of the Type 2 cover plate can be smoothly and tightly coupled with the right side of the Type 1 cover plate. At this time, the Type 2 cover plate is fixed under the support of the Type 1 cover plate. Check the position and stability of the Type 2 cover plate to ensure that it is firmly connected with the Type 1 cover plate without looseness or misalignment. Align the fourth locking structure on the left side of the Type 3 cover plate with the third locking structure on the right side of the Type 2 cover plate. Adjust the position of the Type 3 cover plate with the help of the hook, so that the two sides are accurately fitted. Apply pressure to complete the coupling and locking, and achieve the installation of the Type 3 cover plate. Then, unscrew the hook and screw the anti-theft bolt into the threaded hole at the top of the Type 3 cover plate to further reinforce the Type 3 cover plate and complete the installation of the entire cover plate system.

[0067] Referring to Figure 7 is the installation schematic diagram of the coupled cover plate provided by the embodiment of the present application.

[0068] When placing the cover plate, first place the Type 1 cover plate (starting plate). The installer ensures that the Type 1 cover plate hot-dip galvanized folded flat iron 90° cover frame 1 is tightly attached to the well wall. After placing the starting plate, place the Type 2 cover plate (cooperating plate). The worker ensures that the Type 1 cover plate hot-dip galvanized folded flat iron 45° "convex" cover frame 2 cooperates with the Type 2 cover plate hot-dip galvanized folded flat iron 45° "concave" cover frame 4. The cooperation between the subsequent cooperating plates needs to ensure that the Type 2 cover plate hot-dip galvanized folded flat iron 45° "convex" cover frame 5 and the Type 2 cover plate hot-dip galvanized folded flat iron 45° "concave" cover frame are tightly cooperated. Finally, place the Type 3 cover plate (opening plate). The construction worker ensures that the Type 3 cover plate hot-dip galvanized folded flat iron 45° "concave" cover frame cooperates with the Type 2 cover plate hot-dip galvanized folded flat iron 45° "convex" cover frame.

[0069] After completing the placement of the cover plate, the rubber plug needs to be inserted into the threaded opening hole 7 of the Type 3 cover plate to ensure that there is no accumulation of sundries and water to block the opening hole during daily operation.

[0070] During daily operation, the rubber plug is always inserted into the threaded opening hole of the Type 3 cover plate. When there is a maintenance plan or an emergency that requires the power cover plate to be opened, a special threaded ring needs to be used. The threaded ring cooperates with the opening hole thread, and then the worker pulls the cover plate to open it.

[0071] The step-by-step installation process clearly defines the operation object and connection relationship of each step, so that the installer can complete the installation of each cover plate step by step. The type 1 cover plate serves as a reference to provide accurate positioning reference for the type 2 cover plate, and the type 2 cover plate provides accurate guidance for the installation of the type 3 cover plate. In addition, the uniform size and matching bevel locking structure of each cover plate greatly reduce the probability of misalignment during installation, and improve the installation accuracy of the entire system. The step-by-step locking method gradually transfers the connection force between each cover plate, forming a whole force system, which enhances the stability and anti-deformation ability of the entire cover plate system. Based on the threaded hole provided only on the third cover plate, the difficulty of theft and opening is increased, and the safety is improved. It can effectively prevent the cover plate from loosening, shifting or being stolen, and ensure the safety of the cover plate system during use, and is suitable for scenes with high safety requirements such as roads and municipal facilities.

[0072] In another embodiment provided by the present application, when the number of type 2 cover plates exceeds one, the first locking structure is the same as the third locking structure, and the second locking structure is the same as the fourth locking structure; Before coupling and locking the fourth locking structure on the left side of the type 3 cover plate with the third locking structure on the right side of the type 2 cover plate and installing the type 3 cover plate, the method further comprises: In another embodiment provided by the present application, when the number of type 2 cover plates exceeds one, the first locking structure is the same as the third locking structure, and the second locking structure is the same as the fourth locking structure;

[0073] In the specific implementation of the present embodiment, when the number of type 2 cover plates exceeds one, since the first locking structure is the same as the third locking structure, and the second locking structure is the same as the fourth locking structure, multiple type 2 cover plates can be connected in sequence. The uniformity of the locking structure enables the subsequent type 2 cover plates to be seamlessly connected with the installed type 2 cover plates. The type 1 cover plate serves as a starting reference, and after the first type 2 cover plate is connected thereto, the remaining type 2 cover plates are sequentially coupled by means of the same locking structure, forming a continuous intermediate connection section, and finally connected with the type 3 cover plate to form a complete and stable cover plate system. The high strength of the material ensures the stability of the connection of multiple type 2 cover plates, and the uniform size ensures the smoothness of the installation process.

[0074] During installation, place the type 1 cover plate at the predetermined installation position, adjust it to be stable and accurate in position, ensure that the first locking structure on the right side is correctly oriented, and prepare for subsequent connection. The level can be used to check the levelness. Install the first type 2 cover plate: pick up the first type 2 cover plate, align the second locking structure on the left side with the first locking structure on the right side of the type 1 cover plate, complete the coupling and locking, and check the stability. For each remaining 2-type cover plate, align the second locking structure on the left side with the third locking structure on the right side of the installed 2-type cover plate, and then apply pressure to complete the coupling and locking. Check the connection between each installed 2-type cover plate and the previous one to ensure that there is no looseness or misalignment until all 2-type cover plates are installed. Align the fourth locking structure on the left side of the 3-type cover plate with the third locking structure on the right side of the last 2-type cover plate, adjust the position to fit accurately, and apply pressure to complete the coupling and locking. Then unscrew the hook and screw the anti-theft bolt into the threaded hole for reinforcement, completing the entire system installation. By increasing the installation steps of the remaining 2-type cover plates, the system can flexibly increase the number of 2-type cover plates according to actual needs, adapt to different lengths of installation scenarios, and greatly improve the applicability and expandability of the scheme.

[0075] In another embodiment provided by the present application, the method further comprises: Decouple and lock the fourth locking structure on the left side of the 3-type cover plate from the third locking structure on the right side of the 2-type cover plate, and remove the 3-type cover plate; In turn, decouple and lock the second locking structure on the left side of the rightmost 2-type cover plate, and in turn remove the rightmost 2-type cover plate; Remove the 1-type cover plate.

[0076] In the specific implementation of this embodiment, the disassembly scheme of the cover plate is the reverse operation of the installation process, and the core principle is based on the uniformity of the locking structures of various types of cover plates and the reversibility of the connection.

[0077] The disassembly process follows the logic from back to front, i.e., first remove the last installed 3-type cover plate, then in turn remove the rightmost 2-type cover plate, and finally remove the starting 1-type cover plate. This sequence not only avoids damaging other cover plates or the installation foundation during disassembly, but also takes advantage of the characteristics of the locking structure to easily decouple by targeted force.

[0078] In specific implementation, first remove the 3-type cover plate. Screw the threaded end of the hook into the threaded hole at the top of the 3-type cover plate to ensure a firm connection. Apply an outward pulling force to the ring to gradually separate the fourth locking structure on the left side of the 3-type cover plate from the third locking structure on the right side of the last 2-type cover plate, and decouple and lock. After complete separation, hold the ring to move the 3-type cover plate to the designated storage location and unscrew the hook. Take down the rightmost 2-type cover plate: for the rightmost 2-type cover plate, apply an outward pulling force to make it translate, so that the second locking structure on its left side decouples from the third locking structure on the right side of the previous 2-type cover plate. After taking down this 2-type cover plate, follow the same method to sequentially operate on the remaining 2-type cover plates from right to left. Each time a cover plate is taken down, check its separation from the previous cover plate to ensure that there is no residual connection, until all 2-type cover plates are taken down. Finally, apply an appropriate external force (such as translation or lifting) to the 1-type cover plate to separate it from the installation base (if there is a fixed connection). Since the 1-type cover plate is only connected to the first 2-type cover plate, and the first 2-type cover plate has already been taken down, the 1-type cover plate has no other connection constraints and can be directly moved to the designated storage location, completing the entire disassembly process.

[0079] The locking structure is arranged to allow the cover plates to be disassembled in an orderly manner from the 3-type cover plate to the 2-type cover plate and then to the 1-type cover plate, improving the anti-theft performance.

[0080] The above describes the preferred embodiments of the present application. It should be noted that those skilled in the art can make several improvements and refinements without departing from the principles of the present application, and these improvements and refinements are also considered within the scope of protection of the present application.
