Description

TECHNICAL FIELD

BACKGROUND

[0002] Traditional elevator control cabinets have significant limitations in structural design and functional implementation principles, making it difficult to meet diversified application requirements.

[0003] Unreasonable layout principle, low space utilization: Traditional control cabinets mostly adopt single-layer or simple double-layer layout, and do not design hierarchical logic based on module function correlation and space adaptability, do not fully utilize vertical space, resulting in cabinet volume redundancy, and cannot adapt to narrow installation scenes.

[0004] Lack of expansion structure, difficult to upgrade functions: Lack of standardized expansion connection principle, when adding functions such as earthquake monitoring and remote monitoring, the original cabinet structure needs to be damaged or the entire cabinet needs to be replaced, which essentially means that the modular connection logic of "basic module + expansion module" has not been established.

[0005] Single installation structure, poor scene adaptability: Only rely on ground fixed installation principle, do not design switchable installation support structure, cannot meet special installation needs such as wall hanging, and limit the installation location selection range.

[0006] Defective heat dissipation principle, high operation and maintenance cost: The heat generating components such as frequency conversion modules are designed with shells, and no directional heat dissipation flow channel is formed, and the heat is easy to accumulate; at the same time, the fans and other vulnerable parts do not adopt independent quick release structure, and need to disassemble the associated modules during maintenance, which violates the design principle of "vulnerable parts are maintained separately".

[0007] Low function integration, poor system coordination: The functions such as power supply optimization of electric reactors and noise reduction of contactors need external equipment, and the built-in structure is not designed based on the principle of "function integration in expansion space", resulting in messy system wiring and occupying additional space.

Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them.

[0042] In the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connection", "fixing" and the like should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrated; it can be mechanical connection, or electrical connection; it can be direct connection, or indirect connection through intermediate medium, or internal communication of two elements or interaction relationship between two elements.

[0043] In the present application, unless otherwise explicitly specified and limited, the first feature "on" or "under" the second feature can be direct contact between the first and second features, or indirect contact between the first and second features through an intermediate medium. Moreover, the first feature "above", "over" and "on" the second feature can be directly above or obliquely above the first feature, or only indicate that the horizontal height of the first feature is higher than that of the second feature. The first feature "below", "under" and "under" the second feature can be directly below or obliquely below the first feature, or only indicate that the horizontal height of the first feature is less than that of the second feature.

[0044] As Figures 1-12 shown, the present application realizes the expandable compact elevator control function by the following structural principle design, and the specific technical scheme is as follows:

[0045] 1. Overall structural framework and partition principle

[0046] The core structure is a standard cabinet body 1, which is divided into a top region and a bottom region based on the principle of "centralization of basic control functions". The bottom region is used to install modules with large heat dissipation and high heat dissipation requirements, and the top region is used to install modules with high operation frequency and convenient maintenance, forming a "partition by function characteristics" layout logic. At the same time, at least two outer walls (such as top + bottom, left side + right side) of the standard cabinet body 1 are designed with expansion installation structure, and the detachable assembly of the expansion cabinet is realized based on the principle of "standard interface connection". In addition, mounting components are configured, and the wall-mounted and floor-mounted installation are compatible based on the principle of "switchable support structure".

[0047] 2. Conventional function module and multi-layer layout principle

[0048] The conventional functional modules include a frequency conversion module 2, a master control module 3, a power module 4, and a functional safety module 5, and a multi-layer layout is designed based on the principle of “module interaction near distance + space vertical utilization”:

[0049] The three-layer layout principle of the bottom area is as follows:

[0050] The fixing plate 11 of the frequency conversion module 2 serves as a bottom support, and a support column 12 is arranged on the surface of the fixing plate 11. The height of the support column 12 is designed based on the principle of “shortest path of signal interaction between the master control module 3 and the frequency conversion module 2”, so as to ensure that the distance between the two modules can avoid signal interference and shorten the connection cable. The master control module 3 is fixed at the top end of the support column 12, forming a double-layer structure of “master control module 3 - frequency conversion module 2 electronic board”. Further, the frequency conversion module 2 adopts a shell-free design (removing the redundant shell to reduce space occupation), and the heat sink 13 directly adheres to the side of the electronic board away from the master control module 3, forming a three-layer layout of “master control module 3 - frequency conversion module 2 electronic board - heat sink 13” — this design not only conforms to the heat dissipation principle of the heat sink 13 facing outward, but also fully utilizes the bottom space through vertical layering.

[0051] The three-layer layout principle of the top area is as follows:

[0052] A vertical module mounting plate 14 is arranged at the top of the standard cabinet body 1, and based on the principle of “high-frequency operation module facing outward”, the functional safety module 5 is installed on the side of the module mounting plate 14 facing the cabinet door 15, which is convenient for daily inspection and operation. The power module 4 is divided into a power module one 16 and a power module two 17, and based on the safety principle of “power module away from the operation area”, the power module one 16 is installed on the side of the module mounting plate 14 away from the cabinet door 15, and the power module two 17 is directly fixed to the inner wall of the standard cabinet body 1 away from the cabinet door 15, forming a three-layer layout of “functional safety module 5 - power module one 16 - power module two 17”, which not only avoids the interference of the power module on the operation module, but also maximizes the utilization of the vertical space at the top.

[0053] 3. Extension installation structure and extension cabinet adaptation principle

[0054] The principle of the extension installation structure is as follows:

[0055] The expansion mounting hole 6 and the incoming line hole 7 are opened on the outer wall (left and right upper and lower side walls) of the standard cabinet body 1; the expansion mounting hole 6 is designed based on the principle of "standardized bolt connection", ensuring that different types of expansion cabinets can be fixed through unified fasteners, realizing "one hole fitting multiple cabinets"; the incoming line hole 7 is designed based on the principle of "cable hidden layout", providing the connection cable of the expansion cabinet and the internal module of the standard cabinet body 1 to pass through, avoiding the exposure of the cable and preventing the cable from being worn.

[0056] Expansion cabinet adaptation principle:

[0057] The expansion cabinet includes a top expansion cabinet 8, a bottom expansion cabinet 9, a left expansion cabinet 10, and a right expansion cabinet, and the adaptation logic is based on the principle of "matching function requirements and installation location characteristics":

[0058] The bottom expansion cabinet 9 is designed based on the principle of "heavy components facing down", and the top of the bottom expansion cabinet 9 is designed with a fixing structure matching the bottom expansion mounting hole 6 of the standard cabinet body 1, and is connected stably through fasteners; at the same time, the bottom of the bottom expansion cabinet 9 is provided with a ground installation hole 10, which not only satisfies its own fixation but also shares the overall weight, and is suitable for installing heavy components such as reactors 26 and filters 27;

[0059] The top expansion cabinet 8 is designed based on the principle of "light components facing up", and the bottom is provided with a fixing structure matching the top expansion mounting hole 6 of the standard cabinet body 1, and the top is reserved for installing components — ensuring that after expansion, it can still be adapted to wall-mounted installation based on the principle of "switchable support structure", and is suitable for installing light modules such as I / O communication boards;

[0060] The left expansion cabinet 10 / right expansion cabinet is designed based on the principle of "high-frequency maintenance components facing the side", and the side is provided with a fixing structure matching the corresponding side expansion mounting hole 6 of the standard cabinet body 1, and is suitable for installing components such as DTU modules 25 that need to be frequently checked, and facilitates side door maintenance.

[0061] 4. Heat dissipation structure principle and quick release maintenance design

[0062] Directional heat dissipation channel principle:

[0063] The side plate, back plate and baffle 18 of the standard cabinet body 1 form a closed air duct — the air duct is designed based on the principle of "air flow directionally flowing through heating components", allowing only cold air to enter from the lower part of the cabinet body, flowing through the radiator 13 and then being discharged from the upper part, avoiding air flow short circuiting and causing heat dissipation failure; the function of the baffle 18 is to guide the air flow to flow through the radiator 13, strengthening the heat exchange efficiency.

[0064] Fan module quick release principle:

[0065] Fan module 19 is fixed with fan mounting plate 20, installed in the rear of frequency conversion module 2 in "tilt embedded mode" - the tilt angle is designed based on the principle of "air flow evenly covers the surface of radiator 13", ensuring that the fan module 19 air can fully act on the radiator 13; The lower end of the fan mounting plate 20 is fixed by insertion, and the upper end is connected by hand screw - based on the principle of "easy disassembly of wearing parts", the fan mounting plate 20 can be pulled out by removing the hand screw, realizing the replacement of the fan module 19 without disassembling other modules.

[0066] 5. Installation assembly and cabinet door structure principle

[0067] Dual-mode installation principle:

[0068] The installation assembly includes installation support one 21 (top) and installation support two 22 (bottom), both of which are detachably connected by fasteners - when mounted on the wall, the support serves as an intermediate connection between the standard cabinet body 1 and the wall, based on the principle of "symmetrical support and uniform stress", ensuring that the cabinet is fixed vertically; When installed on the ground, the support can be removed to be directly fixed through the bottom of the standard cabinet body 1, realizing the design logic of "support switching to installation mode switching".

[0069] Cabinet door convenient disassembly principle:

[0070] The upper end of the cabinet door 15 is connected to the standard cabinet body 1 by hand screw, and the lower end is provided with a slot 23 and cooperates with a limiting column 24 of the standard cabinet body 1 - the cooperation between the slot 23 and the limiting column 24 is based on the principle of "positioning and guiding", ensuring accurate alignment when installing the cabinet door 15; The hand screw design is based on the principle of "tool-free disassembly", allowing the cabinet door 15 to be removed without professional tools during routine maintenance, improving operational convenience.

[0071] 6. Integration principle of optional modules

[0072] The optional modules in the expansion cabinet are installed based on the principle of "functionally adaptive expansion space", realizing the coordination of function and structure:

[0073] DTU module 25 installation principle:

[0074] Including DTU electronic board and backup power supply, it is installed on the left and right sides of the standard cabinet body 1 - based on the principle of "side space not affecting the main heat dissipation flow channel", avoiding occupying the core expansion space at the top / bottom; When there is no space on the left and right sides, it can be installed in other positions by lengthening the communication cable, based on the principle of "signal transmission not limited by distance", ensuring that the remote monitoring function is realized normally;

[0075] I / O communication board expansion principle:

[0076] Installed in the expansion cabinet and in communication connection with the main control module 3, based on the "interface expansion" principle, through the addition of a communication interface, the functions of earthquake monitoring, elevator power failure self-power generation and the like are realized in superposition, without the need to modify the original line in the standard cabinet body 1;

[0077] Installation principle of the reactor 26 and the filter 27:

[0078] Preferentially installed in the bottom expansion cabinet 9, based on the dual principles of "heavy component load-bearing adaptation" and "distancing from high-frequency signal module to prevent interference", both the load-bearing capacity of the bottom expansion cabinet 9 is utilized, and electromagnetic interference to the main control module 3 and the like is avoided;

[0079] Design principle of the noise reduction box 28:

[0080] Containing a contactor inside, with sound-absorbing structure on the inner wall —— based on the "acoustic noise reduction" principle, the sound-absorbing cotton absorbs the noise of the contactor in operation, and the sealed box body prevents the noise from being transmitted outside; the plug-in cable connection is adopted, based on the "quick disassembly and assembly" principle, facilitating the separate removal during maintenance.

[0081] The following explains the specific implementation process of the present application in combination with the structural principle:

[0083] Installation support assembly: based on the "symmetrical support" principle, the installation support one 21 is fixed to the top of the standard cabinet body 1, and the installation support two 22 is fixed to the bottom, ensuring that the supports are aligned with the center line of the standard cabinet body 1, and avoiding the stress deviation when hung on the wall;

[0084] Cabinet body wall hanging fixation: according to the wall hanging hole position marking of the installation support one 21 and the installation support two 22, the wall surface is drilled, and the supports are fixed to the wall surface through expansion bolts —— based on the "uniform stress" principle, the symmetry of the bolt distribution is ensured, and the inclination of the cabinet body is prevented;
