Description

Technical Field

[0001] The invention relates to the technical field of power distribution safety, and in particular to an interlocking intelligent identification plate for a power distribution system. Background Art

[0002] The distribution cabinet is a common electrical equipment used to control the on and off of various circuit systems and to provide protection, etc. One or more switches are installed in the distribution cabinet to control the on and off of the circuit. When the switch needs to be opened or closed, you only need to manually control the switch handle.

[0003] In the prior art, the interlocking device and the display screen can be used to lock or open the cabinet door according to the closing and opening state of the switch. When the interlocking device further locks the cabinet door, it plays a role in enhancing safety, is more intelligent, and can realize central control. At the same time, the display screen is set on the cabinet door to display various information in a timely manner, such as displaying warning information prohibiting closing the switch, avoiding the problem of mistaken hanging or removing the sign, and the information update is faster and richer. The existing interlocking device is integrated with the lock core of the cabinet door and interacts with each other. In the interlocking state, if the cabinet door cannot be opened, there will be no erroneous operation such as closing and opening the switch. However, sometimes multiple control modules and multiple circuits are set in the cabinet body. When the demand is only that one of the switches cannot be closed, there is also a demand to close or repair other control modules. The interlocking device prevents the cabinet door from opening, which will affect the related operations of other circuits, resulting in inconvenience in use and potential safety hazards. The existing interlocking device is essentially to prevent the cabinet door from opening by mistake, and cannot directly prevent the switch from being operated by mistake. It is inconvenient to use and has a relatively single scope of application.

[0004] In the prior art, the problem of being unable to prevent the switch from misoperation needs to be solved. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an interlocking intelligent sign for a power distribution system in view of the above-mentioned technical deficiencies, which solves the problem in the prior art that the switch cannot be prevented from misoperation.

[0006] The technical solution adopted by the present invention is: to provide an interlocking intelligent identification plate for a power distribution system, wherein a switch is arranged in a cabinet, a cabinet door can be opened and closed and arranged at the front end of the cabinet, and a display screen is arranged at the front end of the cabinet door; an interlocking device is arranged at the front part of the cabinet, and the interlocking device comprises:

[0012] A linear drive unit is arranged on the positioning block, a moving end of the linear drive unit acts on the positioning member, and the positioning member is moved and arranged on the positioning block by the linear drive unit.

[0013] To further optimize the technical solution, the locking member includes two relatively arranged locking portions, each of which is a semicircular structure and is used to be locked on the switch handle. The switch handle moves with one of the locking portions, and the switch handle passes between the two locking portions.

[0014] Further optimizing the technical solution, the middle part of the cabinet door has an installation window, and further comprising:

[0015] A mounting seat, arranged in the mounting window, and the display screen is arranged on the mounting seat;

[0016] The interlocking block is arranged on the mounting seat and is located in the cabinet. The side of the interlocking block has a locking groove. When the cabinet door is closed, the vertical guide rod and / or the horizontal guide rod are inserted into the locking groove.

[0017] Further optimization of this technical solution also includes:

[0018] A stop edge is arranged on the front side of the side wall of the installation window, and the front end of the installation seat abuts against the inner wall of the stop edge;

[0019] There are a plurality of buckles, which are arranged at the rear side of the side wall of the installation window along annular intervals, and the buckles are clamped at the rear end of the installation seat.

[0020] To further optimize the technical solution, there are two interlocking devices, both of which are arranged at the front of the cabinet, and the side of the interlocking block has a plurality of the positioning grooves, which are used for plugging with the horizontal guide rod or the vertical guide rod.

[0021] To further optimize this technical solution, there are four interlocking devices, and all four interlocking devices are arranged at the front of the cabinet body and are distributed in a "field" grid pattern. The side surface of the interlocking block has a plurality of clamping grooves, and the clamping grooves are used for plugging and setting with the horizontal guide rod or the vertical guide rod.

[0022] To further optimize this technical solution, when the two horizontal guide rods are coaxial, the opposite ends of the two horizontal guide rods are magnetically connected.

DETAILED DESCRIPTION

[0037] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0038] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0039] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0040] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0041] like Figure 1-9As shown, an interlocking intelligent signboard for a power distribution system, wherein a switch is arranged in a cabinet 1, a cabinet door 101 can be opened and closed and is arranged at the front end of the cabinet 1, and a display screen 2 is arranged at the front end of the cabinet door 101; it includes an interlocking device 3, which is arranged at the front of the cabinet 1, and the interlocking device 3 includes: a vertical guide rod 302, which is arranged on the cabinet 1 for horizontal movement; a horizontal guide rod 303, which is arranged on the cabinet 1 for vertical movement, and the horizontal guide rod 303 and the vertical guide rod 302 are perpendicular to each other and are staggered front and back; a positioning block 304, which is vertically slidably arranged on the vertical guide rod 302, and horizontally slidably arranged on the horizontal guide rod 303, after the vertical guide rod 302 and the horizontal guide rod 303 slide, the positioning block 304 is driven to move; a clamping member 305, which is arranged on the positioning block 304 and is used to clamp the switch handle.

[0042] When in use, the vertical guide rod 302 drives the positioning block 304 to move horizontally on the horizontal guide rod 303, and the horizontal guide rod 303 drives the positioning block 304 to move vertically on the vertical guide rod 302. The positioning block 304 can be moved to the switch position in a plane, and the locking piece 305 can be connected to the switch handle to block and limit the path of the switch handle opening and closing up and down, or it can be inserted and abutted on the switch handle to limit excessive movement of the switch handle and avoid misoperation.

[0043] The clamping member 305 can be a conventional structure such as a movable mechanical clamp, a "V"-shaped fork frame, etc., which clamps the switch handle to limit movement.

[0044] The vertical guide rod 302 and the horizontal guide rod 303 can be driven by an existing linear reciprocating drive mechanism, such as a screw mechanism. The ends of the vertical guide rod 302 and the horizontal guide rod 303 are respectively installed on a slider 301, and two screw mechanisms are set. The screws are driven to rotate by a servo motor, and the screws drive the slider 301 to move, thereby realizing the movement of the vertical guide rod 302 and the horizontal guide rod 303; the linear reciprocating drive structure can also adopt a gear rack structure, the rack is fixed to the front end of the cabinet 1 horizontally or vertically, the output end of the motor drives the gear to rotate, and the gear and the rack are meshed, so that the motor can be translated horizontally or vertically, and the vertical guide rod 302 and the horizontal guide rod 303 can follow the movement of the motor. It can also be driven by existing technologies such as timing belt drive mechanisms and electric telescopic rods, which are existing technologies and will not be described in detail in this application.

[0045] When only one vertical guide rod 302 and one horizontal guide rod 303 are arranged in the cabinet 1, the two ends of the vertical guide rod and the horizontal guide rod 303 can be slidably arranged on both sides of the cabinet 1, respectively, and the cabinet 1 is more stable when the span is larger.

[0046] When multiple switches are arranged in the cabinet 1, the multiple switches can be protected separately. The switches may be arranged horizontally or vertically. Therefore, the setting form of the vertical guide rod 302 and the horizontal guide rod 303 can be selected according to the arrangement of the multiple switches. For example, when multiple switches are arranged horizontally at intervals, a horizontal guide rod 303 and multiple vertical guide rods 302, as well as multiple positioning blocks 304 can be set, and the positioning blocks 304 correspond to the switches one by one.

[0047] In order to ensure smooth movement of the positioning block 304, when the positioning block 304 is sleeved and slidably disposed on the vertical guide rod 302 and the horizontal guide rod 303, rolling contact can be achieved through a ball structure, etc., to reduce resistance.

[0048] Furthermore, the clamping member 305 is movably arranged on the positioning block 304, and the clamping member 305 moves closer to or away from the switch handle after moving. The interlocking device 3 also includes: a linear drive unit 306, which is arranged on the positioning block 304. The moving end of the linear drive unit 306 acts on the clamping member 305, and the clamping member 305 is movably arranged on the positioning block 304 through the linear drive unit 306. The clamping member 305 includes two clamping parts 3051 arranged opposite to each other. The clamping parts 3051 are semicircular structures. The clamping parts 3051 are used to clamp on the switch handle. The switch handle moves with one of the clamping parts 3051, and the switch handle passes between the two clamping parts 3051.

[0049] When in use, the linear drive unit 306 controls the locking member 305 to move away from the switch handle to avoid the switch following the movement of the positioning block 304. The switch handle can be locked when it is close to the switch handle to achieve limit positioning to prevent misoperation, making the locking limit of the switch handle more accurate and avoiding the switch handle from moving when it needs to be prevented from misoperation.

[0050] The linear drive unit 306 may be a linear motor module or the like.

[0051] The locking member 305 includes two relatively arranged locking parts 3051 in the shape of a semicircle, which can be half-enclosed and clamped on the switch handle, so as to better clamp and fix the switch handle. At the same time, it can drive the switch handle to move and electrically control the opening and closing of the switch to deal with emergencies, etc., and the switch can be lowered to cut off the power without opening the cabinet door 101.

[0052] When it is necessary to cut off the power, the positioning block 304 moves to the switch handle, and the linear drive unit 306 drives the locking piece 305 to approach the switch handle. The switch handle passes between the ends of the two locking parts 3051 and enters between the two locking parts 3051. Then the positioning block 304 descends, so that the upper locking part 3051 is clamped on the switch handle. At this time, the linear drive unit 306 drives the locking piece 305 to move away from the switch, and the positioning block 304 moves downward at the same time, so that the switch handle can be pulled down to cut off the power. When it is necessary to move the switch handle from small to upward to close the switch and turn on the power, the lower clamping part 3051 is used to clamp it on the switch handle, and then the linear drive unit 306 and the positioning block 304 are moved together. After the closing is completed, the clamping member 305 can keep the switch handle clamped to prevent power failure, or it can be lowered, and the lower clamping member 305 can move the switch handle. The switch handle can be withdrawn from between the two clamping members 305, and then the clamping member 305 is away from the switch handle.

[0053] The distance between the ends of the two locking parts close to the switch handle can be greater than or equal to the diameter of the switch handle, or slightly smaller than the switch handle. When the switch handle enters or exits between the two locking parts, the locking member 305 can avoid it by deformation, but after the switch handle is locked into the locking part, it moves with the locking member 305.

[0054] Furthermore, the cabinet door 101 has an installation window 1011 in the middle, and also includes: a mounting seat 4, which is arranged in the installation window 1011, and the display screen 2 is arranged on the mounting seat 4; an interlocking block 5, which is arranged on the mounting seat 4 and is located in the cabinet body 1, and the side of the interlocking block 5 has a locking groove 501. When the cabinet door 101 is closed, the vertical guide rod 302 and / or the horizontal guide rod 303 are inserted into the locking groove 501.

[0055] When in use, when the cabinet door 101 is closed, the vertical guide rod 302 and / or the horizontal guide rod 303 can be plugged into the locking groove 501 on the interlocking block 5 to prevent the cabinet door 101 from being opened by mistake on site, so as to play a protective role, which is independent of the original lock body structure between the cabinet door 101 and the cabinet body 1, and the protective role is more stable. The lock body structure of the cabinet door 101 is the prior art.

[0056] A plurality of positioning slots 501 may be provided on the side of the interlocking block 5, for example, a vertical positioning slot 501 may be provided on the vertical side, and after the cabinet door 101 is closed, the vertical guide rod 302 moves and is correspondingly inserted into the vertical positioning slot 501 for limiting, thereby preventing the cabinet door 101 from being opened by mistake in a state where the closing of the switch is prohibited, etc. A horizontal positioning slot 501 may also be provided on the horizontal side, and the horizontal guide rod 303 may be correspondingly inserted into the horizontal positioning slot 501, thereby enhancing stability, preventing the cabinet door 101 from being opened by slightly too much force, and preventing misoperation.

[0057] When the vertical guide rod 302 is inserted into the clamping groove 501, the position of the vertical guide rod 302 can be set to correspond to the position of the electric switch. The interlocking block 5 makes a spatial avoidance according to the actual position requirements, and still can operate the electric switch by controlling the movement of the horizontal guide rod 303 and using the clamping member 305.

[0058] Further, it also includes: a retaining edge 1012, which is arranged on the front side of the side wall of the installation window 1011, and the front end of the mounting seat 4 abuts against the inner wall of the retaining edge 1012; a plurality of buckles 1013, which are arranged at intervals along a ring on the rear side of the side wall of the installation window 1011, and the buckles 1013 are clamped to the rear end of the mounting seat 4.

[0059] During use, the mounting seat 4 is clamped between the retaining edge 1012 and the buckles 1013, realizing a fixed installation on the cabinet door 101 that can be disassembled violently, and the display screen 2 is exposed for information display. When an accident occurs, and at the same time there are remote control failures, system failures, etc., resulting in the vertical guide rod 302 being inserted into the clamping groove 501 and unable to be remotely controlled to withdraw, after unlocking the original lock body of the cabinet door 101 on site, the cabinet door 101 still cannot be safely opened for emergency operations such as maintenance. At this time, the cabinet door 101 can be violently pulled, the buckles 1013 are deformed or broken, etc., the cabinet door 101 is disconnected from the mounting seat 4, the cabinet door 101 is opened, and the inside of the cabinet body 1 is exposed. The mounting seat 4 and the interlocking block 5 are fixed in the middle of the front end of the cabinet body 1. The operator can perform emergency operations on the electric switch inside the cabinet body 1 from the surrounding spaced space, and the components affecting the operation can be violently removed. The display screen 2 and some circuit control systems, etc. can be installed in the interlocking block 5 or on the mounting seat 4, and can be relatively completely retained, reducing the loss of violent disassembly. At the same time, it is convenient to still use the display screen 2 for information display and remote control, etc. after the system is restored, to help the on-site personnel record, guide or warn, etc.

[0060] The buckle 1013 can be a conventional structure such as an "L" shape, and can be composed of a thin iron sheet or plastic, etc.

[0061] Further, there are two interlocking devices 3, and both of the two interlocking devices 3 are arranged at the front part of the cabinet body 1. The side surface of the interlocking block 5 has a plurality of clamping grooves 501, and the clamping grooves 501 are used for being inserted and arranged with the horizontal guide rod 303 or the vertical guide rod 302.

[0062] During use, the two interlocking devices 3 can be arranged up and down or left and right, or can be arranged diagonally, and can perform protective operations on multiple electric switches.

[0063] Further, there are four interlocking devices 3, and all four interlocking devices 3 are arranged at the front part of the cabinet body 1 and are distributed in a "field" grid. The side surface of the interlocking block 5 has a plurality of clamping grooves 501, and the clamping grooves 501 are used for being inserted and arranged with the horizontal guide rod 303 or the vertical guide rod 302.

[0064] In use, the four interlocking devices 3 are distributed in a "tian" character grid at the four corner positions. An installation frame 102 can be arranged at the front of the cabinet body 1. The linear reciprocating drive mechanism for driving the vertical guide rods 302 and the horizontal guide rods 303 to move can be installed in the installation frame 102 and installed at the front of the cabinet body 1 as an independent module, which is convenient for installation. The interlocking block 5 can include four sides. The clamping grooves 501 on the left and right sides can be inserted into the vertical guide rods 302, and the clamping grooves 501 on the upper and lower sides can be inserted into the horizontal guide rods 303.

[0065] Furthermore, after the two horizontal guide rods 303 are coaxially aligned, the opposite ends of the two horizontal guide rods 303 are magnetically connected. After the two vertical guide rods 302 are coaxially aligned, the opposite ends of the two vertical guide rods 302 are magnetically connected.

[0066] In use, when four interlocking devices 3 are provided, the two opposite horizontal guide rods 303 on the left and right sides can be coaxially aligned during movement. At this time, the two positioning blocks 304 on the two horizontal guide rods 303 can move on the two horizontal guide rods 303, and a linear reciprocating drive mechanism is required to cooperate with them to achieve long-span linear drive. For example, a rack and pinion structure can be used, and the rack can be laid from the left side to the right side of the cabinet body 1 in the left-right direction. After the two horizontal guide rods 303 are coaxially butted, magnetic attraction is beneficial to improving the coaxiality of the butting position and facilitating the sliding of the positioning block 304. For example, a permanent magnet 601 can be installed at the end of the left horizontal guide rod 303, and a non-magnetic iron 602 can be installed at the end of the right horizontal guide rod 303, etc., to improve the coaxial stability through magnetic attraction.

[0067] Similarly, the coaxiality between the vertical guide rods 302 on the upper and lower sides can also be improved through magnetic attraction, making the position adjustment of the two positioning blocks 304 in the vertical direction more free.
